Description

Technical Field

[0001] This utility model relates to the field of pipe fittings, and in particular to a building waste discharge HPVC pipe fitting with a maintenance mechanism. Background Technology

[0002] HPVC pipe fittings are a type of pipe and connector widely used in building waste disposal systems. With their excellent physical and chemical properties, HPVC pipes have become an important material in building drainage, sewage discharge and wastewater treatment.

[0003] When using wastewater discharge pipes indoors, S-bends are usually connected to the wastewater discharge pipes to prevent odors from escaping. The water flow inside the S-bend isolates the odors, but this also increases the probability of blockage. Therefore, an inspection port is set at the bottom of the S-bend and sealed with a threaded cap. By opening the threaded cap, the inside of the S-bend can be inspected. However, this setting will create a depression at the bottom of the S-bend, which will cause impurities to accumulate at the connection between the threaded cap and the S-bend, thus increasing the likelihood of blockage and presenting a certain defect. Utility Model Content

[0004] The purpose of this utility model is to provide a building waste discharge HPVC pipe fitting with a maintenance mechanism to solve the problems mentioned in the background art.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] This utility model provides, for example Figure 1-3 The image shows a building waste discharge HPVC pipe fitting with a maintenance mechanism.

[0037] Example 1: Includes a waste discharge pipe fitting 1, a connecting pipe 2, a sealing cap 3, and an inner liner assembly 4. The waste discharge pipe fitting 1 has an inspection hole at its bottom. The connecting pipe 2 is fixedly connected to the bottom of the waste discharge pipe fitting 1 and is integrally injection molded with the waste discharge pipe fitting 1. The sealing cap 3 is threaded onto the outside of the connecting pipe 2. The inner liner assembly 4 is installed between the connecting pipe 2 and the sealing cap 3. The inner liner assembly 4 is used to cover and seal the inspection hole, thereby forming a smooth curved surface inside the waste discharge pipe fitting 1, thus reducing the possibility of garbage and impurities clogging the inside of the waste discharge pipe fitting 1.

[0038] Furthermore, the inner lining assembly 4 includes a seal 41, a limiting plate 42, and a drainage assembly 43. The seal 41 is slidably engaged inside the connecting pipe 2, and the top of the seal 41 matches the inner wall of the waste discharge pipe 1. The limiting plate 42 is fixedly connected to the bottom of the seal 41, so that the inside of the waste discharge pipe 1 forms a smooth curved surface. The limiting plate 42 is engaged between the connecting pipe 2 and the sealing cap 3, so that when the sealing cap 3 is connected to the connecting pipe 2, it can squeeze and lock the limiting plate 42, thereby ensuring the stability of the seal 41 installation. The drainage assembly 43 is disposed on the seal 41.

[0039] Furthermore, the inner liner assembly 4 also includes a limiting strip 44, a sliding groove 45, a rubber ring 46, and a sealing gasket 47. The limiting strip 44 is fixedly connected to the inside of the connecting pipe 2. The sliding groove 45 is opened on one side of the seal 41. The outer wall of the limiting strip 44 slides and engages with the inner cavity of the sliding groove 45. The limiting strip 44 allows the seal 41 to be installed at a specified angle, avoiding deviations in the installation angle of the seal 41, which would cause unevenness inside the waste discharge pipe 1. The rubber ring 46 is fixedly sleeved on the outside of the seal 41. An annular groove is opened on the inner wall of the connecting pipe 2. The outer wall of the rubber ring 46 slides and engages with the inner cavity of the annular groove. Thus, when the sealing cap 3 is removed, the rubber ring 46 can limit the seal 41, preventing the seal 41 from falling directly. The sealing gasket 47 is respectively set at the top and bottom of the limiting plate 42. The sealing gasket 47 can improve the sealing performance between the sealing cap 3 and the connecting pipe 2.

[0040] Example 2: Based on Example 1, the drainage assembly 43 includes a sealing block 431, a drainage hole 432, and a button 433. The top of the sealing member 41 is provided with a receiving groove that matches the sealing block 431. The drainage hole 432 is located at the bottom of the inner wall of the receiving groove. The button 433 is fixedly connected to the bottom of the sealing block 431. Thus, when the sealing cap 3 is removed, the sealing member 41 is still located in the connecting pipe 2, and the side of the bottom of the sealing block 431 is in contact with the bottom of the inner wall of the receiving groove, thereby preventing the wastewater inside the waste drain pipe 1 from flowing out directly. Then, the water basin is placed at the bottom of the waste drain pipe 1, and the sealing block 431 is lifted by the button 433, so that the wastewater inside the waste drain pipe 1 can slowly flow out from the drainage hole 432, thereby preventing the wastewater inside the waste drain pipe 1 from being discharged directly when the sealing cap 3 is removed.

[0041] Furthermore, the drainage assembly 43 also includes a first fixing block 434, a second fixing block 436, a guide rod 437, and a limiting spring 435. The first fixing block 434 is fixedly connected to the side of the button 433, the second fixing block 436 is fixedly connected to the inside of the drainage hole 432, the top of the guide rod 437 is fixedly connected to the second fixing block 436, the outer wall of the guide rod 437 is slidably inserted into the first fixing block 434, and the limiting spring 435 is slidably sleeved on the outside of the guide rod 437. The limiting spring 435 is located between the first fixing block 434 and the second fixing block 436. The limiting spring 435 can exert a downward force on the button 433 through the first fixing block 434, thereby causing the button 433 to drive the sealing block 431 to be stably positioned in the storage groove.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
