Built-in plug technology field

The utility model relates to a rubber connection product for flushing and sealing of a squatting toilet, which is called a rubber built-in plug for a squatting toilet.

Built-in plug background technology

At present, the flushing and sealing connection products on the general squatting pan are made of plastic material, which is not only simple in structure, short in service life, and poor in sealing performance, but also leaks due to the inability to tightly integrate with the pipeline and the squatting pan, or thermal expansion and contraction. phenomenon.

Built-in plug invention content

The purpose of the present invention is to provide a rubber built-in plug for flushing and sealing of a squatting pan, which fits closely with the squatting pan and the water inlet pipe, and will not cause a series of problems such as water leakage due to the lack of sealing, so that people can use it more assured more convenient.

The purpose of the present invention is achieved as follows: a rubber built-in plug for flushing and sealing of a squatting pan, which is characterized in that its shape adopts a large taper design, and the diameter of the water inlet of the squatting pan sintered at high temperature has a large deviation, and this structure But it can be applied to all kinds of squatting pan installation.

There are three external water-stop grooves on the outside of this product, which uses a small-cone design, which can ensure the sealing effect of various squatting pans, and it is more convenient to install than ordinary built-in plugs.

The inside of this product adopts an inverted cone design, which is opposite to the pressure of the inlet water. In this way, it can be tightly integrated with the pipe of the squatting pan, and its sealing performance is better.

detailed description

As shown in Figure 1, the rubber built-in plug of the squatting toilet has three water-stop grooves 1 on the outside, which adopts a conical design, and the inside adopts an inverted cone design 2.

The invention is made of high-quality natural rubber materials, which can effectively avoid thermal expansion and contraction and cracking. Even in winter or cold areas, it can maintain good elasticity. long lasting. There are three external water-stop grooves in the structure, and the taper design is used, which makes the installation more convenient and enhances the sealing performance. Moreover, the inner side of the built-in plug adopts an inverted vertebral design, which is opposite to the pressure of the inlet water. In this way, it can be tightly integrated with the pipe of the squatting pan, and its sealing performance is better.
