Description

Technical Field

[0001] This utility model belongs to the field of corrugated pipe technology, and in particular relates to a corrugated pipe that is easy to disassemble. Background Art

[0002] A bellows is a tubular elastic sensing element made of foldable corrugated sheets connected along the folding and stretching direction. Bellows are widely used in building construction, factory production, and instrumentation. Its main purpose is as a measuring element in pressure measuring instruments. It is elastic and converts pressure into displacement or force.

[0003] Chinese utility model patent CN221743451U discloses a corrugated pipe that is easy to install and disassemble. The pipe includes a corrugated pipe body, an insert tube at the left end, and an installation groove at the right end. Several anti-slip strips are provided on the outer wall of the corrugated pipe body near both ends. A slider is symmetrically provided on the outer wall of the insert tube. A groove is provided in the installation groove corresponding to the slider. A rubber gasket is provided on the outer wall of the insert tube near its outer end. This easy-to-install and disassemble corrugated pipe allows adjacent corrugated pipe bodies to be quickly assembled and installed by inserting the insert tube with the slider into the groove in the installation groove. The rubber gasket and the arc-shaped groove help ensure a tight fit between adjacent corrugated pipe bodies, increasing the sealing at the connection. The fixing bolts enhance the overall stability of the installation, and removing the fixing bolts facilitates disassembly and reassembly.

[0004] However, the above-mentioned device has the following technical problems in actual use:

[0005] 1. When assembling two adjacent corrugated pipes, the above-mentioned device inserts the wiping tube on the end of one corrugated pipe into the end of the other corrugated pipe, and then uses a fixing bolt to lock and fix the two. However, there is no protective device for the inserted tube on the outside of the end of the corrugated pipe. If the inserted tube is deformed or worn by external impact, it is easy to deform. The deformed inserted tube cannot guarantee that it can be stably inserted into the end of the other corrugated pipe, thus affecting the subsequent stable assembly of the two adjacent corrugated pipes.

[0006] Second, in addition, the two adjacent corrugated pipes are only connected and fixed by fixing bolts. When the two corrugated pipes deform, the fixing bolts will shift or deform, making it difficult to disassemble the corrugated pipes manually. Utility Model Content

[0007] This invention provides a bellows that is easy to disassemble, aiming to solve the problem mentioned in the background art where the device lacks a protective device for the insert at the end of the bellows. When the bellows (the end with the insert) is impacted before assembly, the insert will deform or wear, which will affect the insertion of the insert into the end of the other bellows, thus affecting the assembly between two adjacent bellows. In addition, in the above device, two adjacent bellows are only fixed by a fixing bolt. When the connection is impacted, the fixing bolt may be displaced or deformed, thus affecting the disassembly of the bellows.

[0008] This utility model is implemented as follows: a corrugated pipe that is easy to disassemble includes: a corrugated pipe body, an extension tube integrally formed and fixedly installed on one end of the corrugated pipe body, and a protective sleeve movably installed on the extension tube; a connecting mechanism disposed at both ends of the corrugated pipe body, and each having: a locking component disposed on the outside of the extension tube, with the protective sleeve sleeved on the outside of the locking component; and a insertion component disposed on the other end of the corrugated pipe body. When two adjacent corrugated pipe bodies are assembled, the protective sleeve moves along the extension tube to one side of the locking component, and the extension tube on one end of the corrugated pipe body is inserted into the insertion component on the other end of the corrugated pipe body. The insertion component and the locking component... The components are detachably connected. In this scheme, when assembling two adjacent bellows bodies, the protective sleeve on one end of the bellows body is first moved to one side of the extension tube through the connection of external and internal threads, exposing the locking component. Then, the extension tube is inserted into the end of the other bellows body with the insertion component, so that the insertion block is inserted into the first locking groove. After the insertion block moves to its end along the first locking groove, one side of the bellows body is rotated so that the insertion block enters the second locking groove. At this time, the threaded hole and the through hole are in the same position, and the end of the other bellows body abuts against the side of the protective sleeve. Then, the threaded section of the locking bolt is threaded through the through hole and connected to the threaded hole to complete the assembly of the two adjacent bellows bodies.

[0009] It should be explained that when the bellows body in this device is not in use, the protective sleeve can be rotated to the extension tube position outside the corresponding locking component by using the thread engagement between the external and internal threads. The protective sleeve protects the end of the extension tube, preventing deformation or wear of the extension tube due to external impact, thereby avoiding the problem of the extension tube becoming unusable.

[0010] In addition, in this device, when two adjacent bellows bodies are assembled, the connection between the bellows bodies is fixed by the cooperation between the insertion block and the first locking groove (second locking groove), and the connection between the locking bolt and the threaded hole is strengthened to prevent separation or deformation between the two adjacent bellows bodies and ensure the stability of subsequent assembly.

[0011] Preferably, the locking assembly includes: two first locking grooves formed on the outer wall of the extension tube, one end of which extends to the end of the extension tube away from the corrugated pipe body, and the other end extends along the outer wall of the extension tube towards the corrugated pipe body. A second locking groove is also formed on the outer wall of the extension tube corresponding to the end of the extension tube near the corrugated pipe body, and the first and second locking grooves are L-shaped. The insertion assembly includes: an insertion block fixed to the inner wall of the end of the corrugated pipe body corresponding to the first locking groove, the insertion block and the first locking groove being transitionally fitted. In this embodiment, a locking assembly is provided at the end of the extension tube away from the corrugated pipe body to which it is connected. Includes: a first locking groove formed on the outer wall of the extension tube, one end of which is connected to the end of the extension tube and the other end extends towards the corrugated tube body. A second locking groove is also formed on the outer wall of the extension tube corresponding to the end of the extension tube near the corrugated tube body. The second locking groove and the first locking groove are perpendicular to each other. When two adjacent corrugated tube bodies are assembled, the extension tube is inserted into the end of the other corrugated tube body, and at the same time, the insertion block is inserted into the first locking groove. After the extension tube is gradually inserted into the end of the corrugated tube body, the insertion block moves gradually along the first locking groove and moves closer to the second locking groove. When the insertion block moves to the end of the first locking groove, one side of the corrugated tube body is rotated so that the insertion block moves into the second locking groove, thereby preventing the two adjacent corrugated tube bodies from separating.

[0012] Preferably, a threaded hole is provided on the outer wall of the end of the extension tube away from the corrugated pipe body, and a through hole is provided on the outer wall of the other end of the corrugated pipe body corresponding to the threaded hole. A locking bolt passes through the through hole, and the threaded section of the locking bolt is threaded into the threaded hole. In this scheme, when the insert block moves into the second locking groove, the position of the through hole and the position of the threaded hole are aligned with each other. After the threaded section of the locking bolt passes through the through hole and is threaded into the threaded hole, the assembly between the two adjacent corrugated pipe bodies can be completed. Conversely, when disassembly is required, simply remove the locking bolt, rotate one side of the corrugated pipe body, move the insert block into the first locking groove, and then pull out the corrugated pipe body to complete the disassembly of the two adjacent corrugated pipe bodies.

[0013] Preferably, there are two first locking grooves, which are symmetrically distributed on the outside of the extension tube, and two threaded holes, which are symmetrically arranged on the outside of the extension tube. The threaded holes and the second locking grooves are positioned correspondingly. In this solution, there are two locking components in the device, which are symmetrically distributed on both sides of the extension tube. The purpose is to ensure uniform force distribution, avoid deformation of the extension tube, and increase the stability.

[0014] Preferably, the extension tube has an external thread on its outer wall on one side of the locking assembly, and the protective sleeve has an internal thread on its inner circumferential wall. The external thread and the internal thread are threaded together. In this embodiment, the protective sleeve has an internal thread on its inner circumferential wall near the corrugated pipe body, and the extension tube on one side of the second locking groove has an external thread along its length. The external thread extends toward the corrugated pipe body. When the protective sleeve is rotated, the screw connection between the internal thread and the external thread allows the protective sleeve to be fitted onto the outside of the locking assembly (or moved to one side of the locking assembly).

[0015] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a corrugated pipe that is easy to disassemble.

[0016] 1. When the bellows body in this device is not in use, the protective sleeve can be rotated to the extension tube position outside the corresponding locking component by using the thread engagement between the external and internal threads. The protective sleeve protects the end of the extension tube to prevent deformation or wear caused by external impact, thereby avoiding the problem of the extension tube becoming unusable.

[0017] 2. In this device, when two adjacent bellows bodies are assembled, the connection between the bellows bodies is fixed by the cooperation between the insert block and the first locking groove (second locking groove), and the connection between the locking bolt and the threaded hole is strengthened to prevent separation or deformation between the two adjacent bellows bodies and ensure the stability of subsequent assembly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Please see Figure 1-5 This utility model provides a technical solution: a corrugated pipe that is easy to disassemble, comprising: a corrugated pipe body 1, an extension tube 11 integrally formed and fixedly installed on one end of the corrugated pipe body 1, and a protective sleeve 12 movably installed on the extension tube 11; a connecting mechanism 2, which is disposed at both ends of the corrugated pipe body 1, and respectively having: a locking component 21 disposed on the outside of the extension tube 11, and the protective sleeve 12 sleeved on the outside of the locking component 21; and a insertion component 22 disposed on the other end of the corrugated pipe body 1. When two adjacent corrugated pipe bodies 1 are assembled, the protective sleeve 12 moves along the extension tube 11 to one side of the locking component 21, and the extension tube 11 on one end of the corrugated pipe body 1 is inserted into the insertion component 22 on the other end of the corrugated pipe body 1. The insertion component 22 and the locking component 21 are detachably connected.

[0033] Specifically, in this device, to ensure the sealing between two adjacent corrugated pipe bodies 1 after connection, a waterproof sealing ring can be fixedly installed at the end of the corrugated pipe body 1 with the insertion component 22. At the same time, a waterproof sealing ring is fixedly installed on the end of the protective sleeve 12 near the locking component 21. During assembly, the protective sleeve 12 is moved along the extension tube 11 to the end position near the end of the corrugated pipe body 1. Then, the extension tube 11 is inserted into the end of the other corrugated pipe body 1 with the insertion component 22, so that the end of the other corrugated pipe body 1 abuts against the end of the protective sleeve 12. The two waterproof sealing rings abut against each other, thereby achieving a waterproof sealing effect at the connection between two adjacent corrugated pipe bodies 1.

[0034] Furthermore, the locking assembly 21 includes two first locking grooves 211 formed on the outer wall of the extension tube 11, one end of which extends to the end of the extension tube 11 away from the corrugated tube body 1, and the other end extends along the outer wall of the extension tube 11 toward the corrugated tube body 1. The first locking grooves 211 are also connected to the second locking grooves 212 formed on the outer wall of the extension tube 11 near the end of the corrugated tube body 1. The first locking grooves 211 and the second locking grooves 212 are L-shaped. The insertion assembly 22 includes an insertion block 221 fixed to the inner wall of the end of the corrugated tube body 1 corresponding to the first locking grooves 211. The insertion block 221 and the first locking grooves 211 are in transitional fit.

[0035] Furthermore, a threaded hole 213 is provided on the outer wall of the end of the extension tube 11 away from the corrugated tube body 1, and a through hole 222 is provided on the outer wall of the other end of the corrugated tube body 1 corresponding to the threaded hole 213. A locking bolt 223 passes through the through hole 222, and the threaded section of the locking bolt 223 is threadedly connected to the threaded hole 213.

[0036] Specifically, in this device, the locking bolt 223 can also be replaced by another connection method, wherein the connection method is as follows:

[0037] An active cavity is formed inside the corrugated pipe body 1, and a through groove is formed on both the outer wall and the inner wall of the corrugated pipe body 1 to connect the active cavity (the inner diameter of the through groove is smaller than the inner cavity size of the active cavity). An insert rod is slidably arranged in the through groove, the insert rod passes through the active cavity, and one end extends to the outside of the corrugated pipe body 1 and a handle is fixed to its end, and the other end extends into the inner hole of the corrugated pipe body 1.

[0038] A limiting piece is fixed to the outer wall of the insert rod inside the movable cavity, and the limiting piece is located on the side near the inner hole of the bellows body 1. A return spring is provided on the limiting piece and the side near the outer wall of the bellows body 1, and the return spring is sleeved on the outside of the insert rod. When the insert rod is pulled outward, the limiting piece moves synchronously and squeezes the return spring. The end of the insert rod in the inner hole of the bellows body 1 moves into the movable cavity. When the insert rod and the threaded hole 213 are aligned, the insert rod is released. Under the rebound action of the return spring, the end of the insert rod is inserted into the threaded hole 213, thus completing the assembly between two adjacent bellows bodies 1. This method can avoid manual disassembly of the locking bolt 223 and also avoid the loss of the locking bolt 223.

[0039] Furthermore, two first locking grooves 211 are provided and are symmetrically distributed on the outside of the extension tube 11, and two threaded holes 213 are provided and are symmetrically disposed on the outside of the extension tube 11. The threaded holes 213 and the second locking grooves 212 are positioned corresponding to each other.

[0040] Furthermore, the extension tube 11 is provided with an external thread 31 on the outer wall of the locking component 21, and the protective sleeve 12 is provided with an internal thread 32 on the inner peripheral wall, and the external thread 31 and the internal thread 32 are threadedly connected.

[0041] Working principle and usage process of this utility model:

[0042] In this device, when assembling two adjacent bellows bodies 1, the protective sleeve 12 on one end of the bellows body 1 is first moved to one side of the extension tube 11 through the connection of the external thread 31 and the internal thread 32, exposing the locking component 21. Then, the extension tube 11 is inserted into the end of the other bellows body 1 with the insertion component 22, so that the insertion block 221 is inserted into the first locking groove 211. After the insertion block 221 moves to its end along the first locking groove 211, one side of the bellows body 1 is rotated so that the insertion block 221 enters the second locking groove 212. At this time, the threaded hole 213 and the through hole 222 are in corresponding positions, and the end of the other bellows body 1 abuts against the side of the protective sleeve 12. Then, the threaded section of the locking bolt 223 is threaded through the through hole 222 and then threaded into the threaded hole 213 to complete the assembly of the two adjacent bellows bodies 1.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
