Description
Technical Field
[0001] The utility model relates to the technical field of plumbing installation, and particularly relates to an anti - detachment pipe - clamping sleeve joint. Background Art
[0002] The low - temperature floor radiant heating technology was introduced into China for use at the end of the 1980s and the beginning of the 1990s. Initially, it was mainly applied to some special places and high - end residences. With the development of technology and the accumulation of application experience, this heating method has gradually become popular and mature. At the beginning of the 21st century, with the rapid development of the domestic economy and the acceleration of the urbanization process, the low - temperature floor radiant heating, as an energy - efficient, comfortable and environmentally friendly heating method, has been more widely used.
[0003] At present, the low - temperature floor radiant heating system in China has been widely promoted in many cities and regions. Especially in some cold regions and northern cities, it has been favored by more and more families and enterprises. This heating method radiates heat through floor or wall heat - dissipation plates, which can effectively improve the comfort of indoor air, reduce air convection and dust suspensions in the traditional heating system, and also has a positive effect on improving indoor air quality.
[0004] In the floor heating system, the heat - collecting and distributing device - the manifold is particularly important. The floor heating manifold is responsible for distributing the hot water transported from the heat source to the floor heating pipes at each heating end and collecting the return water that has released heat in each floor heating pipe and returning it to the heat source. This requires connecting the floor heating pipes and the manifold. Currently, ordinary retaining rings and nuts are used to connect the floor heating pipes and the manifold. When connecting, the lock nut needs to be tightened forcefully. If the lock nut is not tightened tightly enough, there is a possibility of detachment. Once detached, it will cause water leakage at the connection point. In terms of probability, the more connection points there are, the greater the possibility of leakage. However, the connection between the floor heating pipes and the manifold cannot be reduced. Therefore, it is an inevitable measure to improve the connection reliability between the floor heating pipes and the manifold. Summary of the Invention
[0005] Based on the above - mentioned existing technology, the utility model provides an anti - detachment pipe - clamping sleeve joint. The joint has a simple structure and is convenient to use, which can greatly improve the connection reliability between the floor heating pipes and the manifold, and avoid water damage caused by water leakage at the connection between the floor heating pipes and the manifold.
[0006] The technical solution adopted to achieve the above object of the utility model is as follows:
[0007] An anti - detachment ferrule - type joint, comprising a joint body, an elastic snap ring and a locking nut. One end of the joint body is provided with an inner interface and an outer interface. An annular abutting groove is formed between the inner interface and the outer interface. The outer interface is provided with an external thread. The elastic snap ring includes an elastic snap ring body and a plurality of clamping strips evenly distributed circumferentially along the elastic snap ring body. One end of each clamping strip is connected to one end face of the elastic snap ring body. The other end of each clamping strip is provided with a pressing inclined surface. The inner side wall of each clamping strip is provided with a first anti - detachment tooth. The outer side wall of the elastic snap ring body on the side facing away from the clamping strips is provided with a first annular inclined surface. The suspended end of the outer interface is provided with a second annular inclined surface. One end of the inner wall of the locking nut is provided with a third annular inclined surface. The elastic snap ring is locked by the locking nut. The pressing inclined surfaces of the clamping strips cooperate with the second annular inclined surface, and the first annular inclined surface cooperates with the third annular inclined surface.
[0008] The outer side wall of the described clamping strip is parallel to the axis of the elastic snap ring body. The angle between the pressing inclined surface on the clamping strip and its outer side wall is an obtuse angle. The angle between the first annular inclined surface and the outer side wall of the elastic snap ring body is an obtuse angle. The angle between the second annular inclined surface and the outer side wall of the outer interface is an acute angle. The angle between the third annular inclined surface and the inner side wall of the locking nut is an obtuse angle.
[0009] The length of the described inner interface is greater than the length of the outer interface.
[0010] The outer side wall of the inner interface is provided with a first annular protrusion evenly distributed along its axis. The suspended end of the outer side wall of the inner interface is provided with a second anti - detachment tooth.
[0011] Both ends of the inner side wall of the described elastic snap ring body are respectively provided with a second annular protrusion.
[0012] Compared with the prior art, the beneficial effects and advantages of the present utility model are as follows:
[0013] 1. Through the cooperation of the locking nut and the elastic snap ring, the locking nut can lock the elastic snap ring. Since the elastic snap ring has elasticity and is provided with a circle of clamping strips, and the clamping strips are provided with anti - detachment teeth, the anti - detachment teeth can hold against the floor heating pipe, preventing the floor heating pipe from slipping downward, thus achieving the purpose of anti - detachment.

[0026] The following will explain the present utility model in detail with reference to the accompanying drawings
[0027] The structure of the anti - detachment pipe ferrule joint provided in this embodiment is as Figures 1 - 3 shown, including a joint body 1, an elastic retaining ring 8 and a lock nut 14
[0028] One end of the joint body 1 is provided with an inner interface 2 and an outer interface 3. The length of the inner interface 2 is greater than that of the outer interface 3, and an annular abutting groove 4 is formed between the inner interface 2 and the outer interface 3. The outer interface 3 is provided with an external thread, and the suspended end of the outer interface 3 is provided with a second annular inclined surface 5. The included angle between the second annular inclined surface 5 and the outer side wall of the outer interface 3 is an acute angle. The outer side wall of the inner interface 2 is provided with first annular protrusions 6 evenly distributed along its axial direction, and the suspended end of the outer side wall of the inner interface 2 is provided with second anti-disengagement teeth 7. The first annular protrusions 6 and the second anti-disengagement teeth 7 further press the floor heating pipe 16 to further prevent the floor heating pipe 16 from detaching from the joint body.
[0029] As Figures 4 - 5 shown, the elastic retaining ring 8 includes an elastic retaining ring body 9 and a plurality of clamping strips 10. The plurality of clamping strips 10 are evenly distributed circumferentially along the elastic retaining ring body 9. One end of each clamping strip 10 is connected to one end face of the elastic retaining ring body 9, and the outer side wall of the clamping strip 10 is parallel to the axis of the elastic retaining ring body 9. The other end of each clamping strip 10 is provided with a pressing inclined surface 11. The included angle between the pressing inclined surface 11 on each clamping strip 10 and its outer side wall is an obtuse angle, and the pressing inclined surfaces 11 on each clamping strip 10 cooperate with the second annular inclined surface 5. The inner side wall of each clamping strip 10 is provided with first anti-disengagement teeth 12, and the first anti-disengagement teeth 12 can hold against the floor heating pipe 16 to prevent the floor heating pipe 16 from detaching, achieving the purpose of anti-disengagement.
[0030] On the side of the outer side wall of the elastic retaining ring body 9 facing away from the clamping strips 10, there is a first annular inclined surface 13. The included angle between the first annular inclined surface 13 and the outer side wall of the elastic retaining ring body 9 is an obtuse angle. At both ends of the inner side wall of the elastic retaining ring body 9, there are second annular protrusions, and the second annular protrusions can further press the floor heating pipe.
[0031] One end of the inner wall of the lock nut 14 is provided with a third annular inclined surface 15. The first annular inclined surface 13 cooperates with the third annular inclined surface 15. The included angle between the third annular inclined surface 15 and the inner side wall of the lock nut 14 is an obtuse angle.
[0032] The usage method of the above anti-disengagement pipe clamp type joint is as follows:
[0033] 1. Push the floor heating pipe 16 into the elastic retaining ring 8. Each clamping strip 10 is forced to expand. The floor heating pipe 16 passes through the inner hole of the elastic retaining ring 8. As Figure 6 shown, at this time, pull the floor heating pipe 16 in the reverse direction. The floor heating pipe 16 has a force to detach from the elastic retaining ring 8. Due to the elasticity of the elastic retaining ring 8, the anti-disengagement teeth of the elastic retaining ring 8 hold against the floor heating pipe 16 to prevent the floor heating pipe 16 from detaching, thereby achieving the purpose of anti-disengagement;
[0034] 2. Slip the lock nut 14 onto the floor heating pipe 16, as Figure 4 shown;
[0035] 3. Bring the end of the floor heating pipe 16 that is closer to the elastic retaining ring 8 into contact with the abutting groove 4 of the joint body 1, as Figure 5 shown;
[0036] 4. Push the lock nut 14. The lock nut 14 pushes the elastic retaining ring 8 to move towards the joint body 1. When the lock nut 14 comes into contact with the joint body 1, rotate the lock nut 14. The lock nut 14 continues to push the elastic retaining ring 8 towards the joint body. When the pressing inclined surfaces 11 of the clamping strips on the elastic retaining ring 8 are in abutting connection with the second annular inclined surface 5, and the first annular inclined surface 13 is in abutting connection with the third annular inclined surface 15, continue to rotate the lock nut 14 until the lock nut 14 can no longer rotate. At this time, the lock nut 14 locks the elastic retaining ring 8. Since the first anti-detachment teeth 12 are provided on the clamping strips 10 of the elastic retaining ring 8, the pressing inclined surfaces 11 of the clamping strips 10 are in abutting connection with the second annular inclined surface 5, the first annular inclined surface 13 is in abutting connection with the third annular inclined surface 15, annular protrusions are provided on the joint body 1 and the elastic retaining ring body 9, and the elastic retaining ring 8 has elasticity, the floor heating pipe 16 can be reliably connected to the joint body 1. Even if the lock nut 14 is loosened to a certain extent, the floor heating pipe 16 will not come out. In this way, water leakage at the connection between the floor heating pipe and the manifold can be prevented, and water damage can be avoided.
