Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to an anti-detachment type of pipe. Background Technology

[0002] Throughout the progress of human civilization, pipeline systems have always played a crucial role. From their initial use in transporting basic resources such as water and gas, to their widespread application in various fields such as industrial production and urban construction, their importance is self-evident. Among numerous connection technologies, the anti-detachment connector, as an important connection component, is at the forefront of pipeline connection technology development. It focuses on solving the most critical problem in pipeline connections—preventing detachment—and acts as a stabilizing "joint" in various pipeline systems.

[0003] In existing pipework connections, spring clips and other locking mechanisms are used to connect the pipes together during the connection process. However, over long-term use, these spring clip structures are easily susceptible to corrosion and rust due to frequent exposure to various environmental conditions. This corrosion and rust not only reduce the stability and durability of the spring clip structure but can also lead to functional failure, thus affecting the normal operation of the entire equipment. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-detachment type pipe, which aims to solve the problem that common pipe clamping structures in the prior art are prone to corrosion and rust after long-term use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-detachment receiving pipe, comprising: a receiving pipe and a receiving plug, wherein the receiving plug can be inserted into the receiving pipe and tightly fit against the inner wall of the receiving pipe;

[0006] The receiving pipeline includes a connecting pipeline, the inner wall of which has a concave groove, and a sealing element is installed inside the concave groove;

[0007] The connector includes a connector pipe, an inclined connecting section, and a sealing pipe arranged sequentially from the end closest to the connector pipe to the end furthest from the connector pipe. The diameter of the sealing pipe is larger than that of the connector pipe. The outer circumferential surface of the sealing pipe is tightly fitted with the inner wall of the sealing element. The inclined connecting section is used to connect the connector pipe and the sealing pipe. An anti-disengagement element is provided on the outer circumferential surface of the connector pipe. The anti-disengagement element is located at the connection between the connector pipe and the inclined connecting section. The top of the anti-disengagement element is higher than the end face of the sealing pipe, so that when the connector pipe is inserted into the connector pipe, the anti-disengagement element abuts against the sealing element.

[0008] As a preferred embodiment of the present invention, the receiving pipe further includes a first inclined pipe, a first connecting pipe, a second inclined pipe, a second connecting pipe, a third inclined pipe, and a third connecting pipe arranged sequentially from the end near the wiring pipe to the end away from the wiring pipe. The first inclined pipe is used to connect the wiring pipe and the first connecting pipe, the second inclined pipe is used to connect the first connecting pipe and the second connecting pipe, and the third inclined pipe is used to connect the second connecting pipe and the third connecting pipe.

[0009] As a type of anti-detachment receiving pipe according to this utility model, preferably, the diameter of the first connecting pipe is larger than the diameter of the second connecting pipe, and the diameter of the second connecting pipe is larger than the diameter of the third connecting pipe.

[0010] As a type of anti-detachment receiving pipe according to this utility model, preferably, the plug of the plug pipe is bent inward to form a bent section, and the bent section is adapted to the third inclined pipe.

[0014] As a type of anti-detachment receiving pipe according to this utility model, preferably, the anti-detachment component can also be two rectangular elastic plates arranged at intervals on the outer periphery of the plug pipe. The two rectangular elastic plates are connected to the outer periphery of the plug pipe at opposite ends, and the two rectangular elastic plates extend outward toward the sealing component at opposite ends.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This anti-detachment type connector pipe allows the connector plug to be inserted into the connector pipe, and the sealing pipe and the inner wall of the sealing element are tightly fitted to achieve a sealing structure inside the connector pipe.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figure 1-3 The present invention provides the following technical solution: a non-detachable receiving pipe, comprising: a receiving pipe 1 and a receiving plug 2, the receiving plug 2 being able to be inserted into the receiving pipe 1 and tightly fitted to the inner wall of the receiving pipe 1, the receiving pipe 1 comprising a wiring pipe 10, the inner wall of the wiring pipe 10 being provided with a concave groove 101, the concave groove 101 being provided with a sealing element 11, the sealing element 11 being a sealing ring disposed in the concave groove 101.

[0025] The receiving pipe 1 also includes a first inclined pipe 12, a first connecting pipe 13, a second inclined pipe 14, a second connecting pipe 15, a third inclined pipe 16, and a third connecting pipe 17 arranged sequentially from the end near the connecting pipe 10 to the end away from the connecting pipe 10. The first inclined pipe 12 is used to connect the connecting pipe 10 and the first connecting pipe 13, the second inclined pipe 14 is used to connect the first connecting pipe 13 and the second connecting pipe 15, and the third inclined pipe 16 is used to connect the second connecting pipe 15 and the third connecting pipe 17. The inclined pipes and connecting pipes are arranged alternately to form a wave-shaped flow channel structure, which effectively reduces the impact force during the fluid transportation process.

[0026] The diameter of the first connecting pipe 13 is greater than the diameter of the second connecting pipe 15, and the diameter of the second connecting pipe 15 is greater than the diameter of the third connecting pipe 17.

[0027] The outer wall of the sealing ring fits against the inner wall of the first inclined pipe 12 (e.g.) Figure 1 and Figure 2 As shown in the figure, ensure good sealing performance when the fluid passes through the connection to avoid leakage.

[0028] Please see Figure 1-3 The receiving plug 2 includes a plug pipe 20, an inclined connecting section 21, and a sealing pipe 22 arranged sequentially from one end near the receiving pipe 1 to the other end away from the receiving pipe 1. The diameter of the sealing pipe 22 is larger than that of the plug pipe 20, and the diameter of the plug pipe 20 is smaller than that of the sealing pipe 22 by at least 2 mm. The outer circumferential surface of the sealing pipe 22 is tightly fitted with the inner wall of the sealing element 11. The inclined connecting section 21 is used to connect the plug pipe 20 and the sealing pipe 22 to achieve guidance during insertion.

[0029] The plug of the plug pipe 20 is bent inward to form a bent section 201. The bent section 201 is adapted to the third inclined pipe 16. The bent section 201 facilitates the insertion of the plug pipe 20 into the receiving pipe 1. When the bent section 201 contacts the third inclined pipe 16, the plug pipe 20 cannot go deeper.

[0030] The plug conduit 20 and the wiring conduit 10 are intermittently fitted to facilitate the insertion of the plug conduit 20 into the wiring conduit 10. An anti-disengagement component 3 is provided on the outer circumference of the plug conduit 20. The anti-disengagement component 3 is located at the connection between the plug conduit 20 and the inclined connecting section 21. The anti-disengagement component 3 is a right-angled triangular block 31 arranged in a ring around the axis of the plug conduit 20 on the outer circumference of the plug conduit 20. The inclined surface of the right-angled triangular block 31 faces the insertion direction of the plug conduit 20, which facilitates the smooth entry of the right-angled triangular block 31 into the receiving conduit 1. The material used for the right-angled triangular block 31 is corrosion-resistant material.

[0031] The top of the right-angled triangular locking block 31 is higher than the end face of the sealing pipe 22. When the receiving plug 2 is inserted to the limit position, the vertical side of the right-angled triangular locking block 31 abuts against the end of the sealing element 11. The top of the right-angled triangular locking block 31 is chamfered. The chamfer design makes it easy for the right-angled triangular locking block 31 to be smoothly inserted into the wiring pipe 10 during the insertion process, and also prevents the right-angled triangular locking block 31 from damaging the sealing element 11.

[0032] Please see Figure 1-3 Working principle: When the connector 2 is inserted into the connector pipe 1, the bent section 201 of the connector pipe 20 is inserted into the wiring pipe 10. When the connector pipe 20 is inserted, the inclined surface of the right-angled triangular locking block 31 contacts the inner wall of the seal 11, causing the seal 11 to undergo elastic deformation. As the insertion depth increases, the right-angled triangular locking block 31 gradually passes over the step of the inner wall of the seal 11. When the preset position is reached, the seal 11 returns to its original shape, and its end face is tightly fitted with the vertical side of the right-angled triangular locking block 31, realizing axial limiting and anti-disengagement locking. At this time, the sealing pipe 22 is completely fitted with the inner wall of the seal 11, forming a double seal to prevent fluid leakage at the connection.

[0033] Example 2: Please refer to Figure 1 Unlike Embodiment 1, the anti-detachment component 3 is replaced by two rectangular elastic plates 32 spaced vertically on the outer periphery of the plug pipe 20. The two rectangular elastic plates 32 are connected to the outer periphery of the plug pipe 20 at opposite ends, and the two rectangular elastic plates 32 extend outward toward the sealing component 11 at opposite ends.

[0034] When the connector 2 is inserted into the connector pipe 1, the rectangular elastic plate 32 is squeezed by the inner wall of the seal 11 and undergoes elastic deformation, contracting radially along the connector pipe 20. After the rectangular elastic plate 32 passes the inner wall of the seal 11, the rectangular elastic plate 32 returns to its original shape under its own elasticity, and its end abuts against the end face of the seal 11, forming an axial limit to prevent the connector pipe 20 from accidentally coming out. The material used for the rectangular elastic plate 32 is a corrosion-resistant material.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
