Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe technology, and more specifically, to an anti-detachment corrugated pipe. Background Technology

[0002] A bellows is a tubular elastic sensing element made of foldable corrugated sheets connected along the folding and expansion direction. It mainly includes metal bellows, bellows expansion joints, bellows heat exchange tubes, diaphragms, and metal hoses, and is widely used in petrochemical, instrumentation, aerospace, chemical, power, water conservancy, metallurgical and other industries. When bellows are connected using a direct insertion structure, the sockets and spigots of adjacent bellows are directly inserted.

[0003] A search revealed that Chinese patent CN219841202U discloses an anti-detachment corrugated pipe. In this structure, when adjacent pipes are inserted into each other, the elastic teeth of the spigot section are squeezed by the compression part of the socket section and can enter the location of the slot and form a snap-fit ​​with the slot, which can improve the connection efficiency of the pipes and prevent the pipes from detaching after docking.

[0004] However, in actual use, due to the lack of a guiding and positioning structure, it is difficult for operators to quickly and accurately align the two parts during the insertion process of the socket section and the spigot section. It is often necessary to repeatedly adjust the position of the pipe to complete the insertion, which significantly increases the installation time and operation difficulty. Moreover, the anti-detachment relies solely on the single engagement of the elastic teeth and the groove, which is weak against external forces and has poor anti-detachment effect. In view of this, this utility model proposes an anti-detachment corrugated pipe. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anti-detachment corrugated pipe to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an anti-detachment corrugated pipe, comprising a corrugated pipe body, wherein both ends of the corrugated pipe body are integrally formed with a spigot portion and a socket portion, and the spigot portion and socket portion of two adjacent corrugated pipe bodies can be inserted into each other.

[0007] Preferably, a guide anti-detachment structure is provided at the connection between the spigot and the socket. The guide anti-detachment structure includes a mounting ring, which is fixed to the outer wall of the corrugated pipe body and close to the spigot. Two guide rods are fixedly installed on the outer wall of the mounting ring. Both guide rods are L-shaped and symmetrically distributed on the outer wall of the mounting ring with the corrugated pipe body as the axis. The guide rods are connected to a limit nut by external thread. The surface of the guide rods is provided with an external thread groove. The limit nut is threaded to the guide rod through the external thread groove. The guide anti-detachment structure also includes two guide blocks, which are fixed to both sides of the outer wall of the socket. The guide blocks are provided with guide through holes for the guide rods to pass through.

[0008] Preferably, one end of the socket is integrally formed in a ring shape with a plurality of elastic teeth, and the inner wall of the receiving part is provided with a limiting groove adapted to the elastic teeth structure. Each elastic tooth is composed of an elastic arm connected to the socket and a limiting protrusion provided at the free end of the elastic arm.

[0009] Preferably, the outer surface of the socket portion is provided with a plurality of embedding grooves, and a rubber sealing ring is fixedly embedded in the interior of each of the plurality of embedding grooves, and the outer wall of the rubber sealing ring can be fitted to the inner wall of the socket portion.

[0010] The technical effects and advantages of this utility model are as follows: By setting up a guide and anti-detachment structure, and using the guide cooperation of the L-shaped guide rod and the guide block, the spigot and socket can be quickly inserted and positioned without repeated adjustment and alignment, which greatly improves the ease of installation. At the same time, the guide rod position can be firmly fixed by the thread lock of the limit nut and the threaded groove of the guide rod, which prevents the two inserted bellows from loosening due to lateral displacement, and effectively enhances the connection stability. By integrally molding elastic teeth and embedding rubber sealing rings in the spigot, the elastic arms of the elastic teeth can drive the limiting protrusions to engage with the limiting grooves in the socket, forming an axial mechanical limit to prevent the spigot from axially dislodging from the socket. At the same time, the rubber sealing ring can tightly fit the inner wall of the socket, significantly improving the sealing performance of the bellows connection and preventing leakage of the conveyed medium.

[0016] 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.

[0017] As attached Figure 1-4 The corrugated pipe shown includes a corrugated pipe body 1, with a spigot 2 and a socket 3 integrally formed at both ends of the corrugated pipe body 1, and the spigot 2 and socket 3 between two adjacent corrugated pipe bodies 1 can be inserted into each other.

[0018] Specifically, in this structure, when two corrugated pipe bodies 1 are connected, the insertion part 2 at one end of one corrugated pipe body 1 can be inserted into the socket part 3 of the other corrugated pipe body 1 to achieve the connection operation of the two adjacent corrugated pipe bodies 1.

[0019] In this embodiment, as shown in the appendix Figure 1 , 2 As shown in Figures 3 and 4, a guide anti-detachment structure is provided at the connection between the spigot part 2 and the socket part 3. The guide anti-detachment structure includes a mounting ring 4, which is fixed to the outer wall of the corrugated pipe body 1 and close to the spigot part 2. Two guide rods 5 are fixedly installed on the outer wall of the mounting ring 4. Both guide rods 5 are L-shaped and are symmetrically distributed on the outer wall of the mounting ring 4 with the corrugated pipe body 1 as the axis. The guide rods 5 are connected to the external threads of the limit nuts 6. The surface of the guide rods 5 is provided with external thread grooves. The limit nuts 6 are threaded to the guide rods 5 through the external thread grooves. The guide anti-detachment structure also includes two guide blocks 7, which are fixed to the two sides of the outer wall of the socket part 3 respectively. The guide blocks 7 are provided with guide through holes for the guide rods 5 to pass through.

[0020] Specifically, in this structure, when the spigot 2 at one end of one corrugated pipe body 1 is inserted into the socket 3 of another corrugated pipe body 1, in order to play a good role in insertion positioning and guidance and ensure that the spigot 2 is smoothly positioned and inserted into the socket 3, two symmetrically distributed L-shaped guide rods 5 can pass through the guide through hole to one side of the guide block 7. At this time, the positioning and guidance of the spigot 2 into the socket 3 can be realized, improving the convenience of insertion. After the L-shaped guide rod 5 passes through the guide hole to one side of the guide block 7, the limiting nut 6 is threaded onto the outside of the guide rod 5 through the external thread groove and rotated to one side of the guide block 7 to limit the position of the guide rod 5. Thus, the threaded limitation of the limiting nut 6 prevents the guide rod 5 from laterally disengaging from the guide block 7, thereby preventing the two corrugated pipe bodies 1 from loosening due to lateral displacement. This state is shown in the attached figure. Figure 4 As shown.

[0021] In this embodiment, as shown in the appendix Figure 1 , 2 As shown, one end of the insertion part 2 is integrally formed in a ring shape with several elastic teeth. The inner wall of the receiving part 3 is provided with a limiting groove 8 that is adapted to the elastic tooth structure. Each elastic tooth is composed of an elastic arm 9 connected to the insertion part 2 and a limiting protrusion 10 provided at the free end of the elastic arm 9.

[0022] Specifically, in this structure, when one end of the insertion part 2 is inserted into the interior of the socket part 3, under the elastic action of the elastic arm 9, the limiting protrusion 10 can be locked into the limiting groove 8 opened in the socket part 3, which serves to limit the insertion of the insertion part 2 and the socket part 3 and improve the anti-loosening effect. The elastic teeth in this structure can be integrally formed on the pipe and then formed by cutting the slits between the elastic teeth in a second cut.

[0023] In this embodiment, as shown in the appendix Figure 1 , 2 As shown, the outer surface of the socket 2 is provided with several embedding grooves, and a rubber sealing ring 11 is fixedly embedded in the interior of each of the several embedding grooves. The outer wall of the rubber sealing ring 11 can fit against the inner wall of the socket 3.

[0024] Specifically, in this structure, after one end of the spigot 2 is inserted into the interior of the socket 3, the rubber sealing ring 11 adheres to the inner wall of the socket 3, improving the sealing between the spigot 2 and the socket 3.

[0025] Working principle of this utility model: This application provides an anti-loosening corrugated pipe. In specific use, when two adjacent corrugated pipe bodies 1 are connected, when the spigot 2 of one corrugated pipe body 1 is aligned with the socket 3 of the other, the two L-shaped guide rods 5 on the mounting ring 4 on the side of the spigot 2 will pass through the guide through hole of the guide block 7 on the side of the socket 3, providing positioning guidance for the insertion and ensuring that the spigot 2 is smoothly inserted into the socket 3. At the same time, the elastic locking teeth at one end of the spigot 2 will, under the elastic action of the elastic arm 9, cause the limiting protrusion 10 at the free end to engage with the limiting groove 8 on the inner wall of the socket 3, forming a preliminary limit on the spigot 2 and the socket 3 after insertion, reducing the risk of loosening. After the L-shaped guide rod 5 has completely passed through the guide block 7, the limiting nut 6 is installed on the outside of the guide rod 5 through the external thread groove on the surface of the guide rod 5, and the limiting nut 6 is rotated to fit the side of the guide block 7. The position of the guide rod 5 is fixed by the thread limit, so as to prevent the guide rod 5 from laterally disengaging from the guide block 7, thereby preventing the two inserted bellows from loosening due to lateral displacement. After the spigot 2 is fully inserted into the socket 3, the rubber sealing ring 11 embedded in the groove on the outer surface of the spigot 2 will fit tightly against the inner wall of the socket 3, effectively improving the sealing performance of the connection between the two.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
