Description
Technical Field
[0001] This utility model belongs to the field of corrugated pipe technology, and in particular relates to a metal corrugated pipe that is easy to install. Background Technology
[0002] In the field of rapid installation technology for metal corrugated pipes, metal corrugated pipes are key compensation components in pipeline systems. Their installation efficiency and reliability directly affect project progress and long-term operational safety. As the industrial sector increases its requirements for construction cycle, cost control and automation level, the limitations of traditional installation methods are becoming increasingly apparent. Traditional corrugated pipe installation relies on welding, flange bolt tightening, and other processes, requiring professional welders and multiple tools. The installation of a single interface can take 1-2 hours. It is prone to installation failure or sealing failure due to misalignment. Precise calibration is required during installation, which increases the dependence on the skills of the construction personnel. It is impossible to limit the rotation or lateral displacement of the pipe. Therefore, a metal corrugated pipe that is easy to install is proposed. Utility Model Content

[0007] Furthermore, the disassembly assembly includes a second connecting pipe, which is located at the end of the bellows away from the second chuck. A groove is formed at the center of the outer surface of the second connecting pipe. A fixing plate is welded to the side of the second connecting pipe near the bellows. The fixing plate is rectangular, and the outer ring of the fixing plate is curved on the side near the second connecting pipe. The inner wall of the fixing cover has the same diameter as the outer diameter of the fixing plate. Fixing posts are welded to the four corners of the side of the fixing plate away from the second connecting pipe. Tension springs are fitted on the outer surfaces of the four fixing posts.

Pressure plates 213 are welded to all four sides of the inner wall of the cavity of the fixing cover 214. The fixing cover 214 is a regular quadrangular cone cover. The pressure plates 213 are proportionally progressive to the inner wall of the fixing cover 214. The connecting port 215 is... Four cylinders 212 penetrate the inner edge of the 15th ring, each corresponding to a pressure plate 213. Four thrust springs 2115, sleeved on the outside of the cylinders 212, are connected to the outer wall of the connecting pipe 215.

[0017] The disassembly assembly 22 includes a second connecting port 221, which is located at the end of the bellows 111 away from the second chuck 2110. A groove 222 is formed at the center of the outer surface of the second connecting port 221. A fixing plate 227 is welded to the side of the second connecting port 221 near the bellows 111. The fixing plate 227 is a rectangular plate, and the outer ring of the fixing plate 227 near the second connecting port 221 is curved. The inner wall of the fixing cover 214 has the same diameter as the outer diameter of the fixing plate 227.

Tension springs 223 are fitted onto the outer surface of each of the four fixing posts 225. A base plate 224 is welded to the end of each of the four fixing posts 225 away from the fixing plate 227. One end of each of the four tension springs 223 is welded to the base plate 224. A conical slip ring 226 is provided on the side of the fixing plate 227 closest to the base plate 224. The side of the conical slip ring 226 away from the fixing plate 227 is welded to the base plate 224. The inner edge is slidably connected to the outer surface of the four fixed posts 225. Both sides of the conical slip ring 226 are curved. The ends of the four tension springs 223 away from the chassis 224 are connected to the curved surface of the conical slip ring 226. The side of the chassis 224 away from the fixed plate 227 is welded to the end of the bellows 111 away from the chuck 2110. The inner wall of the conical slip ring 226 is slidably connected to the outer surface of the chassis 224 away from the bellows 111. Specifically, when the groove is limited by the cylinder, the bottom of the conical slip ring is pushed to... The fixed plate presses the conical slip ring against the side conical column, causing the side conical column to move outward. Then, the fixed cover is pushed back to disengage the groove one from the limit of the cylinder one. After pulling out the connecting pipe two, the conical slip ring will be pulled back by the tension spring. The spring elasticity provides a continuous preload to increase the tension on the conical slip ring during movement, reducing wear and breakage risk, extending the service life of components, and reducing rust on bolts, springs, and other components during installation, which affects the normal operation of the equipment and greatly increases the maintenance cost of the equipment.
[0018] A specific application of this embodiment is as follows: During use, moving the fixing cover 214 towards the chuck 2110 compresses the thrust spring 2111. The folding cover 211, under pressure, compresses and stores force. Simultaneously, as the fixing cover 214 moves, the groove 2113 slides on the outer surface of the protrusion 2112. The groove 2113, through the protrusion 2112, provides a certain degree of limitation and guidance for the movement trajectory of the fixing cover 214. Furthermore, the movement of the fixing cover 214 causes several pressure plates 213 to move synchronously. At this time, several thrust springs 2115 release their constraint force, which simultaneously drives cylinder 212 to move away from each other. Then, the connecting port 221 on another bellows 111 is inserted into connecting port 215, causing the fixing plate 227 to contact connecting port 215. The fixing cover 214 is then released, allowing it to return to its original position under the thrust of the thrust springs 2111. At this point, the fixing cover 214 is outside the fixing plate 227. Simultaneously, during the resetting process of the fixing cover 214, multiple pressure plates 213 move synchronously. However, at this time, the pressure plates 213... Multiple cylinders 212 are compressed, causing them to move closer together. Simultaneously, multiple pressure plates 213 embed into grooves 222. The cylinders 212, through these grooves, mechanically lock the connecting pipe joint 221, reducing loosening of the connection. Protected by the fixing cover 214 and fixing plate 227, the corrugated pipe installation port receives multiple layers of protection through physical isolation and structural reinforcement, resisting external impacts and frictional wear, preventing scratches or structural deformation of the corrugated pipe surface. This is achieved with the folding cover 211. The protection reduces the risk of rust and damage to the second thrust spring 2111 caused by rainwater. During the resetting process of the fixed cover 214, the inclined surfaces of the two side cones 216 will contact the arc surface of the fixed plate 227. At the same time, the two side cones 216 will move away from each other under the force and compress and contract the first thrust spring 217. Meanwhile, the fixed cover 214 continues to advance. At this time, the side cones 216 will be embedded between the conical slip ring 226 and the fixed plate 227 under the rebound force of the first thrust spring 217, which will further reinforce the limiting of the second connecting pipe 221.
[0019] When disassembly is required, move the retaining cover 214 towards the chuck 2110. With the pressure from the pressure plate 213 removed, the thrust spring 2115 will quickly return the cylinder 212 to its original position. Then, pull the connecting pipe 221 out of the connecting pipe 215. Simultaneously, move the conical slip ring 226 towards the retaining plate 227, causing the two thrust springs 217 to be compressed and pushed back together with the side conical column 216. After releasing the conical slip ring 226, the tension spring 2116... The tension of spring 223 moves towards the chassis 224. The elastic force of spring 223 provides a continuous preload to increase the connection stability of tapered slip ring 226. The tapered surface of tapered slip ring 226 can quickly press the side tapered column 216 back, reducing wear and extending service life. Sealing rings are provided on the side of connecting pipe port 221 away from the fixed plate 227 and on the side of connecting pipe port 1 215 away from the chuck 2110 to improve the following performance of the moving ring, reduce frictional resistance and reduce leakage points.
