Technical Field
[0001] This utility model relates to the field of pipe fittings, specifically to an anti-detachment structure. Background Technology
[0002] In piping systems, socket fittings are crucial components for connecting different pipes, and their stability and sealing are paramount. Traditional socket fitting connections often rely on threaded or flanged connections, but these methods are prone to loosening or leakage under prolonged use or external impact, affecting the normal operation of the piping system.
[0003] To address these issues, various anti-detachment structures have been explored to enhance the connection stability of socket fittings. However, most existing anti-detachment structures are complex, cumbersome to install, and their effectiveness is often compromised in actual use due to material aging and wear. Utility Model Content
[0004] The purpose of this invention is to provide an anti-detachment structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an anti-detachment structure, comprising a clamping block, wherein the clamping block is inserted into the tube body of the socket fitting body, one end of the clamping block is fixed to the surface of an elastic rubber ring, the elastic rubber ring is installed inside the socket fitting body, and a push ring is sleeved at the end of the socket fitting body, wherein the push ring pushes the clamping block to stretch the elastic rubber ring to produce elastic deformation.
[0006] Preferably, both ends of the socket fitting body are provided with side grooves on the outer ring surface. The side grooves are annular grooves, and multiple through holes are provided on the surface of the side grooves. The clamping blocks correspond one-to-one with the through holes. The clamping blocks are inserted into the through holes, and the end of the clamping block extending out of the through hole is provided with a bevel.
[0007] Preferably, both ends of the socket fitting body are provided with inner ring grooves on the inner ring surface, the elastic rubber ring is a circular ring plate, the two ends of the elastic rubber ring are respectively fixed on two parallel side walls of the inner ring groove, the clamping block is an arc-shaped strip, and the other end of the clamping block is fixed on the outer ring surface of the elastic rubber ring.
[0008] Preferably, the push ring is sleeved in the side groove, and the inner ring surface of the push ring has multiple slots, which are annular grooves. A rubber ring is sleeved and fixed on the surface of the side groove, and the rubber ring matches the slot, with the rubber ring inserted into the slot.
[0009] Preferably, the push ring is an "I"-shaped cylindrical tube with multiple insertion holes on its surface. These insertion holes are arranged circumferentially around the inner ring opening of the push ring. A limiting strip is inserted into the insertion hole. The length of the limiting strip is greater than the length of the push ring tube. One end of the limiting strip is fixed to the side wall of the side groove, and the other end of the limiting strip is fitted with a rubber sleeve. The rubber sleeve has a spherical structure and its diameter is larger than the diameter of the insertion hole.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] The anti-detachment structure proposed in this invention, through the combined action of the clamping block and the elastic rubber ring, can firmly clamp the delivery pipe and prevent it from loosening from the end of the socket fitting. Even after prolonged use or under external impact, it maintains connection stability and sealing. The design of the push ring, the rubber ring in the side groove, and the locking groove ensures reliable positioning of the push ring. When the push ring pushes the clamping block into the working state, the rubber sleeve passes through the insertion hole and blocks one side of the push ring, while the rubber ring is inserted into another locking groove, ensuring that the push ring does not move arbitrarily, thus guaranteeing the stable pushing of the clamping block and the firm clamping of the delivery pipe.

[0017] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0018] Please see Figures 1-4 This utility model provides a technical solution: an anti-detachment structure, including a clamping block 6, which is inserted into the tube body of the socket fitting body 1. Both ends of the socket fitting body 1 have side grooves 2 on their outer ring surfaces. The side grooves 2 are annular grooves, and multiple through holes 4 are formed on the surface of the side grooves 2. The clamping block 6 corresponds to each through hole 4. The clamping block 6 is inserted into the through hole 4. One end of the clamping block 6 extending out of the through hole 4 has a bevel 7. One end of the clamping block 6 is fixed to the surface of an elastic rubber ring 5. The elastic rubber ring 5 is installed inside the socket fitting body 1. Both ends of the socket fitting body 1 have inner ring grooves 3 on their inner ring surfaces. The elastic rubber ring 5 is a circular ring plate. Both ends of the elastic rubber ring 5 are respectively fixed to two parallel side walls of the inner ring groove 3. The clamping block 6 is an arc-shaped strip, and the other end of the clamping block 6 is fixed to the outer ring surface of the elastic rubber ring 5. The end of the socket fitting body 1 is fitted with a push ring 8, which pushes the clamping block 6 to stretch the elastic rubber ring 5 to produce elastic deformation.
[0019] In use, sealing gaskets 14 are fixed inside both ends of the socket fitting body 1. After the socket fitting body 1 is screwed between the two conveying pipes, the end of the conveying pipe only squeezes the sealing gasket 14 to achieve a seal after the socket fitting body 1 and the conveying pipe are screwed together. Then, push the push ring 8 into the side groove 2. The push ring 8 pushes the clamping block 6 into the through hole 4 along the inclined surface 7. At this time, the clamping block 6 stretches the elastic rubber ring 5 and deforms. The elastic rubber ring 5 clamps between the clamping block 6 and the conveying pipe to increase the friction between the clamping block 6 and the conveying pipe. The clamping block 6 clamps the conveying pipe to prevent the conveying pipe from loosening from the end of the socket fitting body 1.
[0020] In the side groove 2, the inner ring surface of the push ring 8 is provided with multiple slots 9, which are annular grooves. A rubber ring 10 is fixedly fitted on the surface of the side groove 2. The rubber ring 10 matches the slot 9 and is inserted into the slot 9. The push ring 8 is an "I"-shaped round tube. The surface of the push ring 8 is provided with multiple insertion holes 11. The multiple insertion holes 11 are distributed circumferentially around the inner ring opening of the push ring 8. A limiting strip 12 is inserted into the inside of the insertion hole 11. The rod length of the limiting strip 12 is greater than the tube length of the push ring 8. One end of the limiting strip 12 is fixed to the side wall of the side groove 2. The other end of the limiting strip 12 is fitted with a rubber sleeve 13. The rubber sleeve 13 has a spherical structure and the diameter of the rubber sleeve 13 is greater than the diameter of the insertion hole 11.
[0021] When in use, if the push ring 8 does not press against the clamping block 6, the rubber ring 10 is stuck in a slot 9, and the rubber sleeve 13 is clamped inside the insertion hole 11, thus preventing the push ring 8 from detaching. When one end of the push ring 8 abuts against the side wall of the side groove 2, the rubber sleeve 13 passes through the insertion hole 11 and blocks one side of the push ring 8. The rubber ring 10 is inserted into another slot 9, thus limiting the push ring 8 and ensuring that the push ring 8 pushes the clamping block 6 stably, thereby ensuring that the clamping block 6 firmly clamps the conveying pipe, thus preventing the pipe fitting body 1 from detaching after the connection with the conveying pipe.
[0022] The procedure for using this anti-detachment structure is as follows: Place the push ring 8 (an "I"-shaped round tube) onto the end of the socket fitting body 1, ensuring that the inner ring surface of the push ring 8 fits snugly against the outer ring surface of the socket fitting body 1. Check if the inner ring surface of the push ring 8 has multiple slots 9, and place a fixing rubber ring 10 on the surface of the side groove 2, ensuring that the rubber ring 10 matches the slots 9. Locate multiple insertion holes 11 circumferentially distributed around the inner ring opening on the surface of the push ring 8. Insert the limiting strip 12 into the insertion holes 11, ensuring that the length of the limiting strip 12 is greater than the length of the push ring 8. Fix one end of the limiting strip 12 to the side wall of the side groove 2, and place a fixing rubber sleeve 13 (spherical structure) on the other end, ensuring that the diameter of the rubber sleeve 13 is greater than the diameter of the insertion hole 11. Fix sealing gaskets 14 inside both ends of the socket fitting body 1. Screw the socket fitting body 1 between the two delivery pipes, ensuring that the ends of the delivery pipes tightly press against the sealing gaskets 14 to achieve a seal. Check if the rubber ring 10 is stuck in a slot 9 and confirm that the rubber sleeve 13 is clamped inside the socket 11, achieving initial anti-dislodgement limiting of the push ring 8. Push the push ring 8 into the side groove 2, ensuring that the push ring 8 squeezes the clamping block 6 into the through hole 4 along the inclined surface 7. During this process, the clamping block 6 will stretch the elastic rubber ring 5 to produce elastic deformation. The elastic rubber ring 5 is clamped between the clamping block 6 and the delivery pipe, increasing the friction between the clamping block 6 and the delivery pipe. When one end of the push ring 8 abuts against the side wall of the side groove 2, check if the rubber sleeve 13 passes through the socket 11 and blocks one side of the push ring 8. At the same time, ensure that the rubber ring 10 is inserted inside another slot 9, achieving final limiting of the push ring 8 and ensuring that the push ring 8 stably pushes the clamping block 6. Check if the clamping block 6 firmly clamps the delivery pipe, ensuring that the delivery pipe will not loosen from the end of the socket fitting body 1. Confirm that the connection between the socket fitting body 1 and the delivery pipe is secure and there is no risk of leakage.
