Abstract
Description
Technical Field
[0001] This utility model relates to the field of water supply and drainage pipeline technology, specifically a building water supply and drainage pipeline. Background Technology
[0002] Building water supply and drainage pipes are important systems in building engineering responsible for water supply and sewage discharge.
[0003] Existing building water supply and drainage pipes generally use socket or threaded connections during the connection process. For socket connections, the pipes are first heat-fused and then inserted, or glue is applied to the outer surface of the pipes before insertion. For threaded connections, polyethylene tape needs to be wrapped around the threads before rotating the pipe. Both connection methods are relatively cumbersome, time-consuming, and labor-intensive, increasing the workload of workers. Furthermore, it is inconvenient to disassemble, repair, or replace the pipes later. Therefore, there is a need to provide a building water supply and drainage pipe that can solve the above problems.

[0023] 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.
[0024] Please see Figure 1-5 A building water supply and drainage pipe includes a first pipe 1 and a second pipe 2. The interface end of the first pipe 1 is provided with a middle protruding ring 101. An outer groove 102 is opened on the outer side of the middle protruding ring 101, and an inner groove 103 is opened on the inner side of the middle protruding ring 101. The interface end of the second pipe 2 is provided with an outer protruding ring 201 for inserting into the outer groove 102, and an inner protruding ring 202 for inserting into the inner groove 103 is provided on the inner side of the interface end of the second pipe 2. A fastening component is provided on the outer surface of the joint between the first pipe 1 and the second pipe 2.
[0025] The fastening assembly includes a first fixing collar 3 and a second fixing collar 4. The first fixing collar 3 is fixedly sleeved on the outer surface of the interface end of the first pipe 1, and the second fixing collar 4 is fixedly sleeved on the outer surface of the interface end of the second pipe 2.
[0026] The outer convex ring 201 and the inner convex ring 202 are provided with an intermediate groove 203. The intermediate convex ring 101 is inserted into the intermediate groove 203. The outer surface of the outer convex ring 201 is provided with a clearance groove that cooperates with the outer wall of the outer groove 102. When it is necessary to connect pipe 1 and pipe 2, the interface ends of pipe 1 and pipe 2 are aligned and inserted, so that the outer convex ring 201 and the inner convex ring 202 are respectively inserted into the outer groove 102 and the inner groove 103. At this time, the intermediate convex ring 101 is inserted into the intermediate groove 203. The operation is simple, time-saving and labor-saving.
[0027] The outer groove 102 is equipped with a first sealing ring 5, and the inner groove 103 is equipped with a second sealing ring 6. By setting the first sealing ring 5 and the second sealing ring 6, when the outer protruding ring 201 and the inner protruding ring 202 are inserted into the outer groove 102 and the inner groove 103 respectively, they can effectively contact and squeeze the first sealing ring 5 and the second sealing ring 6, ensuring the sealing performance after the connection of the first pipe 1 and the second pipe 2, and achieving double waterproofing.
[0028] The first fixing collar 3 and the second fixing collar 4 are both arranged with several protrusions. The protrusion of the first fixing collar 3 has a through hole 301. The protrusion of the second fixing collar 4 has a shaft 401. The front end of the shaft 401 passes through the through hole 301 and has an external thread on its outer surface. The front end of the shaft 401 is connected to a fastening nut 402 through the external thread. When the first pipe 1 and the second pipe 2 are aligned and inserted, the shaft 401 on the second fixing collar 4 will pass through the through hole 301 on the first fixing collar 3, and the fastening nut 402 can be rotated and installed, so that the fastening nut 402 presses the first fixing collar 3, ensuring the stability of the connection between the first pipe 1 and the second pipe 2.
[0029] Among them, strip-shaped protrusions 7 are arrayed on the outer surface of pipe 1 and pipe 2. By setting strip-shaped protrusions 7, the structural stability of pipe 1 and pipe 2 can be effectively increased, and the strip-shaped protrusions 7 can effectively reduce the wear on the outer surface of pipe 1 and pipe 2.
[0030] The working principle is as follows: when it is necessary to connect pipe 1 and pipe 2, align the interface ends of pipe 1 and pipe 2 and insert them, so that the outer protruding ring 201 and the inner protruding ring 202 are inserted into the outer slot 102 and the inner slot 103 respectively, and at this time the middle protruding ring 101 is inserted into the middle slot 203. The operation is simple, time-saving and labor-saving.
[0031] Furthermore, after pipe 1 and pipe 2 are aligned and inserted, the shaft 401 on the second fixing collar 4 will pass through the through hole 301 on the first fixing collar 3, thereby allowing the fastening nut 402 to be rotated and installed. This causes the fastening nut 402 to press the first fixing collar 3, ensuring the stability of the connection between pipe 1 and pipe 2. In addition, by setting a first sealing ring 5 and a second sealing ring 6, when the outer convex ring 201 and the inner convex ring 202 are inserted into the outer groove 102 and the inner groove 103 respectively, they can effectively contact and squeeze the first sealing ring 5 and the second sealing ring 6, ensuring the sealing performance after the connection between pipe 1 and pipe 2, and achieving double waterproofing.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
