Abstract
Description
Technical Field
[0001] The utility model relates to the field of pipe fittings, and more specifically, to a pipe fitting. Background Art
[0002] Pipe fittings can form pipelines through which liquids pass. Since the pipelines are long, it is difficult to connect them with integrated pipe fittings, but a large number of adapters and connectors are needed for connection. The quality of connectors and adapters greatly affects the sealing of the pipelines. Once the sealing fails, water will leak.
[0003] The end strength of existing pipe fittings is insufficient, and there is an urgent need for a pipe fitting that can improve the quality of the pipe fitting end, thereby improving the connection quality and reducing the probability of water leakage. Summary of the invention
[0004] The utility model overcomes the shortcomings of the existing pipe fitting ends that are insufficient in strength and easy to be damaged resulting in connection failure, and provides a pipe fitting that can improve the quality of the pipe fitting ends, thereby improving the connection quality and reducing the probability of water leakage.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0006] A pipe fitting comprises a pipe body and a rim, wherein the rim is arranged at the end of the pipe body, the inner wall diameter of the rim is the same as the diameter of the rest of the pipe body, the outer wall of the rim is provided with a first reinforcement part and a second reinforcement part arranged along the circumferential direction of the rim, the first reinforcement part is arranged at the end of the rim, the first reinforcement part is arranged in the middle of the rim, a valley part with a thickness lower than that of the two reinforcement parts is formed between the first reinforcement part and the second reinforcement part, and the side walls and the valley part of the first reinforcement part and the second reinforcement part form a positioning seat for a positioning clamp.
[0007] The clamp can provide radial pressure to the pipe fitting at various locations in the circumferential direction, so that the pipe fitting and the plug-in pipe fitting fit more closely, thereby reducing the probability of water leakage.
[0008] Because the connection method between the pipe fitting and other pipe fittings is that the other pipe fittings are inserted into the rim, the diameter of the inner wall of the rim is set to be the same as the diameter of the pipe body, so as to achieve direct plug-in.
[0009] Due to the influence of the material, the rim will shrink during production and the accuracy will also be affected. By providing the first reinforcement part and the second reinforcement part, the above can be avoided and the roundness of the rim can be maintained.
[0010] Since the thickness of the edge is lower than the rest of the tube body, the first reinforcement part and the second reinforcement part are provided as reinforcement ribs to strengthen the strength of the end, thereby avoiding sealing failure caused by end damage and avoiding uneven force that affects the service life.
[0011] Thirdly, by providing the first reinforcement part, the second reinforcement part and the valley part, the clamp can be fully positioned, making the clamp easier to install, maintaining the coaxiality of the clamp and the edge, eliminating the stress caused by the coaxiality deviation, and increasing the radial pressure.
[0012] Preferably, the cross section of the first reinforcement portion is rectangular.
[0013] Preferably, the second reinforcement portion includes an annular convex ring arranged in the circumferential direction and a group of convex points arranged at equal intervals on the annular convex ring, wherein the group of convex points includes a plurality of convex points, and the height of the convex points is higher than the surface of the rim. The friction force is increased by the structure, making it easier to plug the two pipes.
[0014] Preferably, the edge of the mouth is provided with a reinforcement convex point below the convex point group in the length direction, and the reinforcement convex point is larger than the convex point. The structure further improves the overall strength, and the reinforcement convex point is used to disperse the stress of the edge of the mouth.
[0015] Preferably, the cross section of the second reinforcement portion is circular.
[0016] Preferably, spherical protrusions are arranged at equal intervals on the second reinforcement part. The friction force is increased by the structure to avoid slipping.
[0017] Preferably, the second reinforcement portion is provided with a plurality of arc-shaped grooves with connected edges.
[0018] Preferably, the width of the valley portion is adapted to the width of the clamp. The above structure improves the coaxiality between the clamp and the edge, eliminates the stress caused by the coaxiality deviation, and increases the radial pressure.
[0019] Compared with the prior art, the beneficial effects of the utility model are:
[0020] (1) The first reinforcement part and the second reinforcement part are used to improve the end strength of the pipe fitting and the precision of the edge;
[0021] (2) The first reinforcement portion, the second reinforcement portion and the valley portion are used to position the clamp, thereby making the installation of the clamp easier. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Example:
[0032] A pipe fitting comprises a pipe body 1 and a rim 2, wherein the rim 2 is arranged at the end of the pipe body 1, the inner wall diameter of the rim 2 is the same as the diameter of the rest of the pipe body 1, the outer wall of the rim 2 is provided with a first reinforcement part 3 and a second reinforcement part 4 arranged along the circumferential direction of the rim 2, the first reinforcement part 3 is arranged at the end of the rim 2, the first reinforcement part 3 is arranged in the middle of the rim 2, a valley part 5 with a thickness lower than that of the two reinforcement parts is formed between the first reinforcement part 3 and the second reinforcement part 4, and the side walls of the first reinforcement part 3, the second reinforcement part 4 and the valley part 5 form a positioning seat for a positioning clamp.
[0033] In some embodiments, the pipe body 1 is a three-way pipe.
[0034] The clamp can provide radial pressure to the pipe in various places in the circumferential direction, so that the pipe and the plugged pipe fit more closely, thereby reducing the probability of water leakage. In some embodiments, the width of the valley 5 is adapted to the width of the clamp. The above structure improves the coaxiality of the clamp and the edge 2, eliminates the stress caused by the coaxiality deviation, and increases the radial pressure.
[0035] Because the connection method between the pipe fitting and other pipe fittings is that the other pipe fittings are inserted into the rim 2, the diameter of the inner wall of the rim 2 is set to be the same as the diameter of the pipe body 1, so as to be directly plugged in.
[0036] Due to the influence of the material, the rim 2 will shrink during production and the precision will also be affected. The above can be avoided by providing the first reinforcement part 3 and the second reinforcement part 4 to maintain the roundness of the rim 2.
[0037] Since the thickness of the rim 2 is lower than the rest of the tube body 1, the first reinforcement part 3 and the second reinforcement part 4 are provided as reinforcement ribs to strengthen the strength of the end portion, thereby avoiding sealing failure caused by end damage and avoiding uneven force that affects the service life.
[0038] Again, by providing the first reinforcement portion 3, the second reinforcement portion 4 and the valley portion 5, the clamp can be fully positioned, making the clamp easier to install, maintaining the coaxiality of the clamp and the edge 2, eliminating the stress caused by the coaxiality deviation, and increasing the radial pressure.
[0039] The cross section of the first reinforcement portion 3 is rectangular. Figure 1 As shown, in some embodiments, the second reinforcement portion 4 includes an annular convex ring 6 arranged in the circumferential direction and a group of convex points 7 arranged at equal intervals on the annular convex ring 6, and the group of convex points 7 includes a plurality of convex points, and the height of the convex points is higher than the surface of the rim 2. The friction force is increased by the structure, making it easier to plug the two tubes. In some possible embodiments, the rim 2 is further provided with a reinforcement convex point 8 below the convex point group 7 in the length direction, and the reinforcement convex point 8 is larger than the convex point. The structure further improves the overall strength, and the reinforcement convex point 8 is used to disperse the stress of the rim 2. Figure 2 As shown, in other embodiments, the second reinforcement portion 4 is provided with a plurality of arc-shaped grooves 9 with edges connected to each other.
[0040] Ginseng Figure 3 As shown, the cross section of the second reinforcement part 4 is circular. In some embodiments, spherical protrusions 10 are arranged at equal intervals on the second reinforcement part 4. The friction force is increased by the structure to avoid slipping.
[0041] The above-described embodiments are only preferred solutions of the present invention and are not intended to limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
