Description
Technical Field
[0001] The utility model relates to the technical field of housing construction engineering, in particular to a portable PVC pipe fitting. Background Art
[0002] PVC materials play a major role in building materials. With the development of the times, various materials are being updated. Previously, when drainage pipes passed through the floor slab, generally holes were reserved. During the construction of the pipes passing through the floor slab, the interfaces were all loose joints. Using ordinary pipe fittings was convenient for construction, but the subsequent treatment of the holes and the waterproofing of the holes were rather cumbersome. Now, in order to avoid hole and waterproof treatment. Generally, a water stop joint pipe is pre-buried, and there is no need to deal with the hole problem later. However, due to the limited distance between floors, each floor and the PVC pipe interface must have a fixed joint, and the construction of the fixed joint is difficult and the quality cannot be guaranteed. Leakage at the interface is also likely to occur later. Summary of the Utility Model
[0003] The purpose of the utility model is to solve the problems of difficult construction during the connection of existing PVC pipes at the fixed joint and easy leakage at the interface later, and to propose a portable PVC pipe fitting.
[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0005] A portable PVC pipe fitting includes a first half pipe with an interface branch pipe installed on the side, and a second half pipe clamped to the first half pipe. A clamping interface is provided between the first half pipe and the second half pipe, and glue is applied inside the clamping interface.
[0006] Further, the clamping interface includes a clamping convex block provided on the first half pipe and a clamping concave block provided on the second half pipe corresponding to the clamping convex block, and glue is applied to the contact surface between the clamping convex block and the clamping concave block.
[0007] Further, an anti-blocking ring is provided inside the second half pipe.
[0008] Further, the inner diameter of the anti-blocking ring corresponds to the inner diameter of the external connecting pipe.
[0009] Further, the radial width of the anti-blocking ring at one end close to the medium flow direction is smaller than the width at the end far from the medium flow direction.
[0010] Further, the side wall of the anti-blocking ring close to the inner wall of the first half pipe or the second half pipe is a vertical surface, and the side wall of the anti-blocking ring close to the center is an arc surface.
[0011] Further, the anti-blocking ring includes an outer ring, and the cross section of the outer ring is in an inverted V shape.
[0012] Further, the outer ring is of a rigid structure.
[0013] Furthermore, the outer ring is an elastic structure.
[0014] Furthermore, an inner ring is arranged inside the outer ring. The inner ring is a rigid structure, and a chamfer is arranged at the bottom of the outer wall of the outer ring.
[0015] Compared with the prior art, the present utility model provides a portable PVC pipe fitting, which has the following beneficial effects:
[0016] When the portable PVC pipe fitting of the present utility model is used, first buckle the second half pipe at the interfaces of the two outer connecting pipes, then buckle the first half pipe at the interfaces of the two outer connecting pipes and engage with the second half pipe. Glue is applied for sealing between the first half pipe, the second half pipe and the outer connecting pipe.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0029] Refer to Figures 1-8 , a portable PVC pipe fitting of the present invention includes a first half pipe 1 with an interface branch pipe 101 installed on the side, and a second half pipe 2 clamped to the first half pipe 1. The interface branch pipe 101 is provided with a cover for connecting to an external pipe. The first half pipe 1 and the second half pipe 2 are obtained by cutting a pipe clamp along the axial direction into two semi-circular pipes. The inner diameters of the first half pipe 1 and the second half pipe 2 correspond to the outer diameter of the outer connecting pipe 5. A clamping interface 3 is processed between the side walls of the first half pipe 1 and the second half pipe 2. When in use, directly buckle the first half pipe 1 and the second half pipe 2 between two outer connecting pipes 5, and apply glue between the first half pipe 1, the second half pipe 2 and the outer connecting pipe 5, and inside the clamping interface 3 for bonding and sealing.
[0030] The clamping interface 3 includes a clamping projection 301 provided on the first half pipe 1 and a clamping recess 302 provided on the second half pipe 2 corresponding to the clamping projection 301. Glue is applied to the contact surface between the clamping projection 301 and the clamping recess 302. Specifically, as Figure 3 shown, from a top view angle, the left side of the clamping projection 301 is recessed outward from the first half pipe 1, and the right end protrudes inward from the first half pipe 1. The left end of the clamping recess 302 protrudes outward from the first half pipe 1, and the right side is recessed inward from the first half pipe 1. And the sizes of the clamping projection 301 and the clamping recess 302 are the same, so that the clamping projection 301 and the clamping recess 302 are clamped together.
[0031] An anti-blocking ring 4 is installed inside the second half pipe 2. The outer diameter value of the anti-blocking ring 4 is the same as the inner diameter values of the first half pipe 1 and the second half pipe 2. Half of the anti-blocking ring 4 is fixedly connected to the second half pipe 2, and the other half is exposed outside the second half pipe 2 and is fixedly glued to the first half pipe 1. When the medium flows through, it is used to prevent foreign objects from getting stuck at the end of the outer connecting pipe at the connection, so that the medium in the pipeline can pass smoothly and prevent the pipeline from being blocked.
[0032] The inner diameter of the anti-blocking ring 4 corresponds to the inner diameter of the outer connecting pipe 5 to avoid forming a step between the anti-blocking ring 4 and the end of the outer connecting pipe 5, reducing the accumulation and jamming of foreign objects.
[0033] The radial width of the anti-blocking ring 4 near the end where the medium comes from is smaller than that at the end away from the direction where the medium comes from. Generally speaking, pipeline installation is mainly divided into vertical connection, horizontal connection and inclined connection. Taking vertical connection as an example, the medium mainly flows from top to bottom. The top end of the anti-blocking ring 4 is located at the end close to the direction where the medium comes from, and the width of the top end of the anti-blocking ring 4 is smaller than that of the bottom end. Preferably, the top end is a pointed tip.
[0034] The side wall of the anti-blocking ring 4 close to the inner wall of the first half pipe 1 or the second half pipe 2 is a vertical plane, which is vertical in the axial direction and annular in the radial direction. In this way, it can be closely attached to the inner walls of the first half pipe 1 and the second half pipe 2, increasing the effective contact area. The side wall of the anti-blocking ring 4 close to the center is an arc surface, specifically as Figure 6 , and the arc surface reduces the accumulation of foreign objects.
[0035] The anti-blocking ring 4 includes an outer ring 401, and the cross-section of the outer ring 401 is an inverted V shape. In this application, the pointed part of the outer ring 401 faces the direction where the medium comes from, including the cases of vertical, horizontal and inclined installation. While ensuring the anti-blocking effect, the hollow outer ring 401 can reduce the material consumption.
[0036] The outer ring 401 is a rigid structure. For example, the outer ring 401 is a metal ring, a fiberglass ring, a rigid plastic ring or other rigid material structures. The main function is that when docking the first half pipe 1 and the second half pipe 2, it can maintain a good original shape and is not easy to deform, so as to maintain the anti-blocking effect.
[0037] The outer ring 401 can also be an elastic structure, which has an elastic deformation effect. The outer ring 401 of the elastic structure has a good contact effect with the first half pipe 1, the second half pipe 2 and the outer connecting pipe 5. After applying glue, with the bonding effect of the glue, an excellent sealing effect is achieved.
[0038] An inner ring 402 is installed inside the outer ring 401. The inner ring 402 is a rigid structure. By using the inner ring 402 to support the outer ring 401, the outer ring 401 is not easy to deform while having a good sealing effect.
[0039] A chamfer 403 is machined at the bottom of the outer wall of the outer ring 401, which is convenient for the first half pipe 1 and the second half pipe 2 to be slid and clamped together.
[0040] Working principle: When in use, first apply glue on the outer wall of the end of the outer connecting pipe 5, the inner walls of the two ends of the second half pipe 2, and the bottom of the anti-blocking ring 4. Align the anti-blocking ring 4 with the end of the lower outer connecting pipe 5, and then clamp the second half pipe 2 between the two outer connecting pipes 5, so that the bottom end of the anti-blocking ring 4 is docked with the lower outer connecting pipe 5.
[0041] Next, apply glue on the inner walls at both ends of the first half pipe 1, on the outer wall of the other half of the anti-blocking ring 4, on the inner wall of the clamping projection 301, and on the outer wall of the clamping recess 302. The following two methods can be selected to achieve docking with the second half pipe 2:
[0042] Method 1: Align the heights of the first half pipe 1 and the second half pipe 2, and then move the first half pipe 1 radially. Directly clamp the first half pipe 1 on the two outer connecting pipes 5, and use extrusion or gently tap with a rubber hammer to make the clamping projection 301 and the clamping recess 302 be clamped and adhesively fixed together.
[0043] Method 2: Directly put the first half pipe 1 on one of the lower outer connecting pipes 5, align the clamping projection 301 and the clamping recess 302, and then push the first half pipe 1 axially (it can also be tapped and moved with a rubber hammer) to make the clamping projection 301 and the clamping recess 302 be slidably connected together and finally completely clamped together. In this process, the rounded corner 403 enables the first half pipe 1 to slide smoothly from bottom to top, avoiding abutment and jamming between the inner wall of the first half pipe 1 and the outer wall of the outer ring 401.
[0044] Just select the above installation method according to the actual installation environment.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
