Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe technology, specifically to a leak-proof spliced ​​corrugated pipe. Background Technology

[0002] A corrugated pipe is a tubular component with a periodic corrugated wall structure, possessing flexibility, extensibility, or bending characteristics. It is used to compensate for displacement, absorb vibration, or transport media. Leak-proof spliced ​​corrugated pipes are tubular components that combine flexible compensation and strong sealing performance through a segmented splicing structure, and are used to transport fluids or gases.

[0003] The existing method of splicing corrugated pipes is mostly to align and then insert them. Once the corrugated pipe is deformed, gaps are easily generated at the splice, which will eventually lead to leakage of gas or liquid inside the pipe.

[0004] Therefore, a leak-proof spliced ​​corrugated pipe is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a leak-proof spliced ​​corrugated pipe to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof spliced ​​corrugated pipe, comprising a corrugated pipe, A sealing unit is placed outside the bellows. The sealing unit includes a sealing component and a leak-proof component. The sealing component is used to wrap and seal the connection between the two bellows, and the leak-proof component is used to prevent the sealing component from leaking. An auxiliary unit is placed inside the sealing unit. The auxiliary unit is used to seal and insert the two bellows together. When the two bellows are spliced, the two bellows can be sealed and inserted under the restriction of the auxiliary unit. With the cooperation of the sealing unit, the external sealing sleeve of the connection can be applied to avoid gaps at the bellows connection that could lead to gas and liquid leakage.

[0007] Preferably, the sealing assembly includes a collar, an air bladder is connected inside the collar, a connecting pipe is connected to the outer wall of the collar, and a cap is fitted on the outer wall of the connecting pipe.

[0008] Preferably, the air-leakage prevention component includes a cross plate, a square rod is slidably connected inside the cross plate, a frustum plate is connected to the end of the square rod, a spring is sleeved on the outer wall of the square rod, and a frustum groove is formed on the inner wall of the connecting pipe.

[0009] Preferably, the outer wall of the frustum disc is adapted to fit the inside of the frustum groove, and the frustum disc is slidably disposed inside the connecting pipe. Under the constraint of the frustum disc and the frustum groove, gas leakage inside the airbag can be avoided.

[0010] Preferably, one end of the spring is connected to the bottom of the frustum, and the end of the spring away from the frustum is connected to the side of the cross plate near the frustum. Under the elastic action of the spring, the frustum that is not pushed by the gas can be reset.

[0011] Preferably, the cross plate is placed inside the connecting pipe, and the outer wall of the cross plate is connected to the inner wall of the connecting pipe. With the support of the cross plate, the frustum can slide stably inside the connecting pipe.

[0012] Preferably, the auxiliary unit includes a sealing main ring, and a sealing secondary ring is connected to the outer wall of the sealing main ring.

[0013] Preferably, there are four sealing sub-rings, which are equidistantly distributed on the outer wall of the sealing main ring. The sealing main ring is sleeved with the bellows. Under the constraint of the equidistantly distributed sealing sub-rings, the sealing performance of the bellows splicing can be further improved.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, when splicing corrugated pipes, first insert two pipes, then put on the collar, remove the connecting pipe cap, and connect the air pump supply pipe. During inflation, the gas pushes the frustum disc to compress the spring, causing it to disengage from the frustum groove of the connecting pipe, and the airbag expands to fill the splice joint; after inflation, the spring returns to its original position, causing the frustum disc to lock into the frustum groove to prevent air leakage, and the cap is replaced to further ensure a seal. To deflate, simply push the frustum disc. This structure prevents deformation and leakage through airbag sealing and also prevents air leakage to maintain a tight fit. 2. In this invention, when inserting two corrugated pipes, the sealing main ring and the equally spaced sealing sub-rings on the outer wall are placed at the corrugation spacing at the end of the first corrugated pipe, and then the second corrugated pipe is inserted. The sealing main ring and sub-rings form a multiple seal. Even if one ring fails slightly, the others can still seal. The multiple sets of settings further improve the splicing sealing performance and prevent leakage during transportation. Attached Figure Description

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0023] Example 1 Reference Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides a leak-proof spliced ​​corrugated pipe, including a corrugated pipe 1. Sealing unit 2, the sealing unit 2 is placed outside the bellows 1, the sealing unit 2 includes a sealing component and an air leakage prevention component, the sealing component is used to wrap and seal the connection between the two bellows 1, and the air leakage prevention component is used to prevent the sealing component from leaking. Auxiliary unit 3 is placed inside sealing unit 2 and is used to seal and insert the two bellows 1.

[0024] When two bellows 1 are spliced ​​together, under the constraint of the auxiliary unit 3, the two bellows 1 can be sealed and inserted. With the cooperation of the sealing unit 2, an external seal can be applied to the connection to prevent gaps from forming at the connection of the bellows 1, which could lead to gas and liquid leakage.

[0025] Example 2 Reference Figure 3 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiment, as follows: The sealing assembly includes a collar 21, an airbag 22 is connected inside the collar 21, a connecting tube 23 is connected to the outer wall of the collar 21, and a cap 24 is fitted on the outer wall of the connecting tube 23. The air-leakage prevention component includes a cross plate 25, a square rod 26 is slidably connected inside the cross plate 25, a frustum plate 27 is connected to the end of the square rod 26, a spring 28 is sleeved on the outer wall of the square rod 26, and a frustum groove 29 is opened on the inner wall of the connecting pipe 23.

[0026] The outer wall of the frustum plate 27 is fitted with the inside of the frustum groove 29, and the frustum plate 27 and the connecting pipe 23 are slidably arranged inside. Under the restriction of the frustum plate 27 and the frustum groove 29, gas leakage inside the airbag 22 can be avoided.

[0027] One end of the spring 28 is connected to the bottom of the frustum 27, and the other end of the spring 28 away from the frustum 27 is connected to the side of the cross plate 25 near the frustum 27. Under the elastic action of the spring 28, the frustum 27, which is not pushed by the gas, can be reset.

[0028] The cross plate 25 is placed inside the connecting tube 23, and the outer wall of the cross plate 25 is connected to the inner wall of the connecting tube 23. With the support of the cross plate 25, the frustum disk 27 can slide stably inside the connecting tube 23.

[0029] When splicing two bellows 1, insert the two bellows 1 together, then place the collar 21 on the outside of the bellows 1, remove the cap 24 from the outer wall of the connecting pipe 23, and thread the air pump supply pipe to the connecting pipe 23. The air pump supplies air to the collar 21 and the inside of the airbag 22. The air pushes the frustum disc 27, which drives the square rod 26 to slide inside the cross plate 25, compressing the spring 28 fitted on the outer wall of the square rod 26. At this time, the outer wall of the frustum disc 27 is no longer fitted with the frustum groove 29 opened on the inner wall of the connecting pipe 23, allowing the airbag 22 to be inflated and filled at the splice of the two bellows 1. After inflation, filling, and sealing are completed, the air no longer pushes the frustum disc 27. Under the elastic action of the spring 28, the frustum disc 27 returns to its original position and fits onto the inner wall of the frustum groove 29. Under its restraint, the airbag 22 can be prevented from deflating, thus avoiding poor sealing. After inflation, the cap 24 and connecting tube 23 are fitted together to further prevent gas leakage from the airbag 22. When deflating the airbag 22, simply push the frustum plate 27 towards the cross plate 25. This structure can seal the joint of the two bellows 1, preventing deformation of the bellows 1 from causing gaps at the joint. Furthermore, this structure provides anti-leakage protection for the airbag 22, ensuring that the airbag 22 remains in close contact with and filled against the outer wall of the bellows 1.

[0030] Example 3 Reference Figure 5 and Figure 6 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as detailed below: The auxiliary unit 3 includes a sealing main ring 31, and a sealing sub-ring 32 is connected to the outer wall of the sealing main ring 31.

[0031] There are four sealing sub-rings 32, which are equidistantly distributed on the outer wall of the sealing main ring 31. The sealing main ring 31 is sleeved with the bellows 1. Under the constraint of the equidistantly distributed sealing sub-rings 32, the splicing sealing performance of the bellows 1 can be further improved.

[0032] When two bellows 1 are fitted together, the sealing main ring 31 and the sealing secondary ring 32 are fitted at the corrugation spacing of the end of the first bellows 1, and then the end of the first bellows 1 is inserted into the interior of the second bellows 1. Under the constraint of the sealing main ring 31 and the sealing secondary ring 32, the insertion point can be sealed again. Since the sealing secondary rings 32 are equidistantly distributed on the outer wall of the sealing main ring 31, under its constraint, multiple sealing secondary rings 32 form a multiple sealing barrier. Even if one ring fails slightly, the other rings can still maintain the seal, greatly reducing the risk of leakage. Multiple sets of sealing main rings 31 and sealing secondary rings 32 further improve the sealing performance of the bellows 1 splice and avoid splice leakage. This structure can provide auxiliary sealing for two spliced ​​bellows 1 to avoid leakage during transportation, and under the constraint of the sealing secondary rings 32, the sealing performance is further improved.

[0033] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
