Description

Technical Field

[0001] The utility model application relates to the technical field of pipe inserts, in particular to a crack-resistant and leak-proof pipe insert. Background Art

[0002] Pipe fittings are a general term for components in piping systems that perform functions such as connection, control, direction change, diversion, sealing, and support. Inserts can reinforce and seal the connection between pipe fittings and water pipes. They are generally made of metal, glass, wood, fiber, paper, rubber or other materials. Therefore, inserts are installed between most water pipes and pipe fittings.

[0003] Most of the current multi-bundle pipe body inserts can only achieve sealing or reinforcement performance. For many water pipes and pipe fittings that are not installed in a temperature environment, the water pipes and pipe fittings will shrink when in a low temperature environment. However, when the shrinkage ratio of the water pipes and pipe fittings is inconsistent, gaps will appear between the water pipes and the pipe fittings or the pipe body on the outer side will crack, which greatly reduces the practicality of the pipe insert. Summary of the invention

[0004] In order to solve the problem that the existing pipe inserts do not have anti-cracking performance, the utility model provides an anti-cracking and anti-leakage pipe insert to solve the above problem.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A crack-resistant and leak-proof pipe insert comprises a pipe fitting 1 and a connecting water pipe, wherein a pipe fitting 2 is fixedly passed through one side of the pipe fitting, the connecting water pipe is sleeved on the pipe fitting 1 or the pipe fitting 2, a buffer rubber pad 1 is fixedly provided on the inner surface of the pipe fitting 1, a buffer rubber pad 2 is fixedly provided on the outer surface of the pipe fitting 2, an auxiliary support plate is fixedly provided on the outer surface of the pipe fitting 1 near the two ends, a support plate is fixedly provided on the outer surface of the end of the connecting water pipe, and a sealing reinforcement plate is fixedly provided on the side of the support plate near the pipe fitting 1 or the pipe fitting 2, and a reinforcement connection groove cooperating with the sealing reinforcement plate is provided inside the pipe fitting 1 and the auxiliary support plate.

[0007] Furthermore, the outer surface of the buffer rubber pad is fitted with the inner surface of the connecting water pipe or the inner surface of the connecting water pipe is fitted with the outer surface of the second pipe fitting, and the side of the connecting water pipe is welded and fixed to the pipe fitting on the inner wall side of the first pipe fitting or the side of the second pipe fitting.

[0008] Furthermore, the lengths of the buffer rubber pad 1 and the buffer rubber pad 2 are both equal to the length between the support plate and the end of the connecting water pipe.

[0009] Furthermore, the sealing reinforcement plate and the reinforcement connection groove are both configured as mutually matching rings, and the buffer rubber pad 1 and the buffer rubber pad 2 are respectively configured as hollow cylinders that match the pipe fitting 1 and the pipe fitting 2.

[0010] Furthermore, the length of each of the sealing reinforcement plates is equal to the length of the reinforcement connection groove, and the thickness of the two sealing reinforcement plates is greater than the thickness of the reinforcement connection groove.

[0011] Furthermore, the sealing reinforcement plate and the reinforcement connection groove are bonded and fixed, and the sealing reinforcement plate and the inner and outer ring walls of the reinforcement connection groove are non-contact plug-in.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] In the utility model, by using the buffer rubber pad structured when connecting the water pipe and the pipe fitting one or the pipe fitting two, when the water pipe and the pipe fitting are cooled, they will produce expansion and contraction deformation, and the buffer rubber pad one or the buffer rubber pad two can be pulled by extrusion or stretching, so as to avoid the formation of gaps or direct cracks, and avoid mutual extrusion between the water pipe and the pipe fitting, thereby solving the problem that the existing pipe fitting inserts do not have crack resistance, and improving the safety and service life of the pipe fitting inlays when in use.

[0020] Reference Figure 1 , Figure 2 and Figure 3 A crack-resistant and leak-proof pipe insert comprises a pipe 1 and a connecting water pipe 5. A pipe 2 is fixed through the side of the pipe 1. The connecting water pipe 5 is sleeved on the pipe 1 or the pipe 2. A buffer rubber pad 3 is fixed on the inner surface of the pipe 1. A buffer rubber pad 4 is fixed on the outer surface of the pipe 2. The outer surface of the buffer rubber pad 3 fits the inner surface of the connecting water pipe 5 or the inner surface of the connecting water pipe 5 fits the outer surface of the pipe 2. The side of the connecting water pipe 5 fits the inner wall of the pipe 1 or the side of the pipe 2. The pipe fitting 1 on the side is welded and fixed, an auxiliary support plate 9 is fixed to the outer surface of the pipe fitting 1 near the end of the pipe fitting 2, a support plate 6 is fixed to the outer surface of the end of the connecting water pipe 5, the lengths of the buffer rubber pad 1 3 and the buffer rubber pad 2 4 are both equal to the length from the support plate 6 to the end of the connecting water pipe 5, and a sealing reinforcement plate 7 is fixed to the side of the support plate 6 near the pipe fitting 1 or the pipe fitting 2, and the pipe fitting 1 and the auxiliary support plate 9 are both provided with reinforcement connection grooves 8 that cooperate with the sealing reinforcement plate 7.

[0021] Specifically, when pipe fitting 1, pipe fitting 2 or connecting water pipe 5 shrinks and deforms when exposed to cold, when the deformation of pipe fitting 1 and pipe fitting 2 is greater than the deformation of connecting water pipe 5, buffer rubber pad 1 3 or buffer rubber pad 2 4 will be squeezed; when the deformation of pipe fitting 1 and pipe fitting 2 is less than the deformation of connecting water pipe 5, buffer rubber pad 1 3 or buffer rubber pad 2 4 will be pulled, thereby protecting pipe fitting 1, pipe fitting 2 and connecting water pipe 5 to avoid gaps or cracks.

[0022] As an optimization solution, Figure 3 As shown, the sealing reinforcement plate 7 and the reinforcement connection groove 8 are both configured as mutually matching rings, the buffer rubber pad 1 3 and the buffer rubber pad 2 4 are respectively configured as hollow cylinders that match the pipe fitting 1 and the pipe fitting 2 2, the length of each sealing reinforcement plate 7 is equal to the length of the reinforcement connection groove 8, the thickness of the two sealing reinforcement plates 7 is greater than the thickness of the reinforcement connection groove 8, the sealing reinforcement plate 7 and the reinforcement connection groove 8 are bonded and fixed, and the inner and outer ring walls of the sealing reinforcement plate 7 and the reinforcement connection groove 8 are non-contact plug-in.

[0023] Specifically, the connection between pipe fitting 1 and the connecting water pipe 5 or between pipe fitting 2 and the connecting water pipe 5 is reinforced by the sealing reinforcement plate 7 and the reinforcement connecting groove 8, so that the connection between the two is more firm and stable, and the remaining deformation space prevents the sealing reinforcement plate 7 from being deformed by cold and causing extrusion force to act in the reinforcement connecting groove 8.
