Abstract
Description
Technical Field
[0001] The utility model relates to the field of connecting pipes, in particular to a bathroom connecting pipe with good sealing performance. Background Art
[0002] The connecting pipe refers to the pipe used to connect the water inlet pipe and pipeline of bathroom products. In order to improve the explosion-proof performance of the connecting pipe, a layer of corrugated pipe or braided layer is usually set on the surface.
[0003] In order to improve the water tightness of the connection between the connecting pipe and the pipeline, a sealing ring is generally placed at the connection. However, due to the high water pressure in the connecting pipe and the sealing ring being easily damaged under the action of hot and cold water, the sealing of the connection between the connecting pipe and the pipeline is reduced and leakage occurs. The purpose of the utility model is to propose a new connecting pipe structure to solve the above technical problems. Utility Model Content
[0004] The utility model aims to provide a bathroom connecting pipe with good sealing performance to solve the problems mentioned in the background technology.
[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: including a tube body, a connecting cap, a supporting ring, a limiting rubber ring and a sealing ring, the connecting caps are located at both ends of the tube body, a thread that can be connected to the pipeline is opened on the inner side of the connecting cap, the supporting ring is located on the inner side of the connecting cap and surrounds the end of the tube body, a limiting groove is formed on the top surface of the supporting ring, the limiting rubber ring is placed on the supporting ring, located on the inner side and the outer side of the supporting ring, and several sealing rings with different diameters are placed between the limiting rubber rings, the centers of the sealing rings coincide and the hardness of the sealing rings is less than the hardness of the supporting rings.
[0006] To optimize the above technical solution, further measures are taken: grooves that can accommodate the limiting rubber ring are formed on the inner and outer sides of the support ring respectively, and the limiting rubber ring is prevented from running on the support ring by providing the grooves on the support ring.
[0007] As a further improvement to the above technical solution: it also includes a disc spring, which is placed on the limiting groove to resist the sealing ring. When the sealing ring is worn, the compressed disc spring can bulge so that the sealing ring is close to the pipe to ensure the sealing of the connection.
[0008] As a further improvement of the technical solution: the surface of the disc spring is wrapped with rubber, the purpose of which is to improve the sealing of the contact parts between the disc spring and the limiting rubber ring and the sealing ring. The rubber can deform to fill the gap and block the passage of liquid, thereby improving water tightness.
[0009] As an improvement to the above-mentioned technical solution: the cross-section of the limiting groove is V-shaped, and the V-shaped structure can reduce the movement of the disc spring and reduce the displacement.
[0010] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:
[0011] The utility model provides a bathroom connecting pipe with good sealing performance, which adopts a mutually independent sealing ring and a limiting rubber ring to cooperate with each other to achieve the sealing of the connecting pipe and the pipeline connection. When a local sealing ring is defective, the sealing rings are independent of each other to ensure that the intact sealing ring can still work stably to ensure the sealing performance. At the same time, the continuous squeezing of the disc spring can also cause the defective part of the sealing ring to deform, which can reduce the defective area and reduce leakage.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] Example
[0019] See also Figure 1-3 The utility model provides a bathroom connecting pipe with good sealing performance, comprising a pipe body 1, a connecting cap 2, a supporting ring 3, a limiting rubber ring 4, a sealing ring 5 and a disc spring 6.
[0020] The connecting caps 2 are located at both ends of the pipe body 1 , and threads that can be connected to the pipe are formed on the inner side of the connecting caps 2 . The connecting caps 2 can be connected and fixed to the pipe through the threaded connection.
[0021] The support ring 3 is located inside the connection cap 2 and surrounds the end of the tube body 1 . A limiting groove 301 is formed on the top surface of the support ring 3 . The cross section of the limiting groove 301 is V-shaped.
[0022] The limiting rubber ring 4 is placed on the support ring 3, located inside and outside the support ring 3. The inside and outside of the support ring 3 are respectively formed with grooves 302 that can accommodate the limiting rubber ring 4. The grooves 302 can limit the limiting rubber ring 4 to prevent the limiting rubber ring 4 from shifting.
[0023] Several sealing rings 5 with different diameters are placed between the limiting rubber rings 4. The centers of the sealing rings 5 coincide with each other and the hardness of the sealing rings 5 is less than that of the supporting ring 3. The limiting rubber ring 4 can clamp the sealing ring 5 through the hardness difference.
[0024] The disc spring 6 is placed on the limiting groove 301 to press against the sealing ring 5 , and the surface of the disc spring 6 is wrapped by rubber.
[0025] Working principle: Connect the connection cap 2 to the pipeline, and the disc spring 6 will squeeze the limit rubber ring 4 and the sealing ring 5 to make them close to the end of the pipeline, so as to prevent water from leaking through the gap between the connection cap 2 and the pipeline and causing dripping.
[0026] When a sealing ring 5 is damaged, the adjacent sealing rings 5 are independent of each other and thus can still play a water-isolating role to prevent water from flowing through. In addition, the disc spring 6 can continue to apply pressure to the sealing ring 5. When the sealing ring 5 is partially damaged, the sealing ring 5 can be squeezed down by the disc spring 6 and fit tightly against the pipe, which helps to reduce the defect and prevent water from flowing through.
[0027] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
