What is a kids potty pot

Kids potty pots are different in size from adult toilets, the most important being the width and height. Due to the child's health, it's too high and it's very tiring to sit on it; it's too wide, and it's inconvenient to open the two legs; the inner circle of the adult toilet is relatively large, and the child's butt is easy to fall and get stuck in it, which is not safe . So buying a suitable kids potty pot is very necessary. A suitable kids potty pot must not only be cute, but also have a safe material. Advantages of kids potty pot : 1. Economical and practical, strong practicability 2. Connect with adult toilet, easy to use 3. Comfortable and safe, easy to clean if accidentally soiled 4. Save you money from buying a child's spittoon 5. No need to spend extra time to clean the baby's poop Features of kids potty pot: 1. The chassis is made of non-toxic new PP material, strong and soft, and feels good! The seat cushion is soft and non-slip, not sticky to

What are the classification and characteristics of kids potty pot

More and more families are willing to buy special kids potty pot for their babies. It is not only economical and affordable, but also guarantees the safety of babies when they enter the toilet. Today, we will tell you about the classification and characteristics of kids potty pot . 1. Distinguish by style kids potty pot on the market can be divided into two categories, free-standing toilets and toilet seats used with household toilets, which can also be subdivided into the following styles. Let's start with the free-standing toilet. (1) Straddle toilet Let the baby sit with feet apart, it is easier for young babies to maintain balance. Generally, the front of the straddle toilet is equipped with a handle, which is convenient for the baby to hold when going to the toilet and avoid falling forward. However, there is a problem with the straddle toilet. When using it, you must take off your pants. It is only suitable for babies wearing open crotch pants. There are still many controvers

What is O-ring

O ring is a kind of rubber ring with a circular cross-section. Because its cross-section is O-shaped, it is called O-ring. It is the most widely used one in hydraulic and pneumatic transmission systems. Usually called O Ring in Taiwanese and Japanese companies. O ring is an annular rubber sealing ring with a circular cross-section. It is mainly used for mechanical parts to prevent the leakage of liquid and gaseous media under static conditions. In some cases. O-ring can also be used for axial reciprocating motion And the dynamic sealing element of low-speed rotating motion. According to different conditions, different materials can be selected to suit it. O-rings are usually selected as large cross-section O-rings as possible. In the case of the same gap, the volume of O-rings squeezed into the gap should be less than the maximum allowable value of squeezed into.  For different types of fixed sealing or dynamic sealing applications, o-ring seals provide designers with an effective and

Several factors affecting the sealing performance of O-rings

The following are 6 major factors that affect the sealing performance of O ring :  1. Movement speed When the movement speed is very low (<0.03m/s), the smoothness of the equipment operation and whether there is "creeping" phenomenon should be considered. When the moving speed is very high (>0.8m/s), the lubricating oil film may be destroyed, and the oil seal will not get good lubrication and friction and heat will cause the service life to be greatly reduced. It is recommended that polyurethane or rubber-plastic oil seals work within the speed range of 0.03m/s~0.8m/s. 2. Temperature Low temperature will reduce the elasticity of polyurethane or rubber-plastic oil seals, causing leakage, and even the entire oil seal becomes hard and brittle. High temperature will cause the volume of the oil seal to expand and soften, resulting in a rapid increase in friction resistance of the oil seal and a decrease in pressure resistance during movement. It is recommended that the conti

Causes, failure modes and solutions of O-ring seal failure

1. The main reason for the failure of O-ring seal (1) The sealing groove design is unreasonable; (2) O-ring is not compatible with the medium used; (3) The size of O-ring seal is incorrectly selected; (4) The O-ring seal cannot be sufficiently lubricated. In addition, because the force of the sealing ring is more complicated, some reasons are difficult to diagnose and judge. If necessary, test and study its material and use environment. 2. Common failure forms and solutions (1) O-rings are flat after use ①The main reason is that the material elasticity and heat resistance of the sealing ring are poor. After the O-ring is used in the working medium of the hydraulic system for a period of time, the sealing ring is often over-expanded and the pressing force increases. This is because in the production process of the seal ring, the rubber vulcanization is not complete enough, so under the action of pressure, the three sides of the seal ring section are pressed into a flat shape; ②The solu

CNC stands for Computer Numerical Controlled and is used to automate the machines tools for the production of components or products. The CNC machining involves end to end design of the component with CAD CAM systems. The CAD/CAM systems create commands which can automatically operate the CNC machines. Following is the process of CNC Machining : 1. Create a model/blue print of the component to be produced / machined 2. Create a process of flow of the raw material to the final component 3. Write CNC programs for the system for machining 4. Schedule a run time for the CNC machine 5. Check the quality of the raw materials to be used 6. Set up the CNC machine 7. Produce some samples of the components to be produced 8. Check the samples for quality and design 9. Adjust the settings based on the check on samples 10. Run the machine to produce with components with continuous quality checks 11. Final inspection There are numerous benefits of using CNC machines for production 1. You can achieve

What are the composition of the plastic injection molding

Although the structure of the mold may vary widely due to the variety and performance of plastics, the shape and structure of plastic products, and the type of injection machine, the basic structure is the same. The mold is mainly composed of pouring system, temperature control system, molding parts and structural parts. Among them, the pouring system and the molded parts are the parts that directly touch the plastic, and change with the plastic and the product. They are the most messy and the largest changes in the plastic mold, and require the highest processing finish and precision. The plastic injection molding  is composed of a movable mold and a fixed mold. The movable mold is installed on the movable template of the plastic injection molding machine, and the fixed mold is installed on the fixed template of the plastic injection molding machine. During plastic injection molding, the movable mold and the fixed mold are closed to form a pouring system and cavity. When the mold is o

Basic structure of injection mold

The structure of the plastic injection molding is determined by factors such as the form of the injection machine and the complexity of the part. Regardless of its complexity, all plastic injection molding can be divided into two parts: a movable mold and a fixed mold. The fixed mold is installed on the fixed template of the injection machine, and the movable mold is installed on the movable template of the injection machine. The moving and fixed molds close the molding cavity and pouring system during injection, and the moving and fixed molds are separated when the mold is opened, and the plastic parts are taken out. According to the role played by each part on the mold, it can be subdivided into the following parts: (1) Molded parts Molded parts are parts that make up the cavity in the designated and movable mold part. It is usually composed of punch (or core), die, insert, etc. (2) Pouring system The pouring system is the channel through which the molten plastic flows from the nozz

The importance of injection mold maintenance

As the most important molding equipment for the processing of injection molded products, injection molds are directly related to the quality of products. Moreover, since the mold occupies a large proportion of the production cost of injection molding processing enterprises, its service life directly affects the cost of injection molded products. Therefore, improving the quality of plastic injection molding, maintaining and maintaining them well, and prolonging their service life are important issues for injection molding product processing enterprises to reduce costs and increase efficiency.  Therefore, the maintenance of the plastic injection molding is very important, as follows: 1. The processing company should first equip each pair of molds with a resume card to record and count its use, care (lubrication, cleaning, rust prevention) and damage in detail. Based on this, it can find out which parts and components have been damaged and the degree of wear. Provide information materia
