Technical Field
[0001] This utility model relates to the field of corrugated pipe technology, and more specifically to a corrugated pipe connector that is easy to install. Background Technology
[0002] Metal bellows is a flexible pipe element made of thin-walled metal with a ring or spiral corrugated structure on its surface. It has both elastic deformation capacity and pressure bearing capacity. Its development originated from the demand for innovation in pipe connection technology during the 19th-century Industrial Revolution. It was initially used for sealing and compensation in equipment such as steam engines.
[0003] Since the 20th century, with the advancement of materials science and manufacturing processes, materials such as stainless steel and high-temperature alloys have been widely used in petrochemical, nuclear power, aerospace and other fields. Modern metal corrugated pipes, through the optimization of processes such as hydroforming and multi-layer welding, can not only effectively absorb the thermal expansion and contraction and mechanical vibration of pipeline systems, but also develop high-performance variants such as composite reinforced types, becoming an indispensable key component in modern industrial pipeline systems.
[0004] However, most existing corrugated pipes are installed using flange connections, which require rotating each fixing bolt individually. This process is cumbersome, time-consuming, and inconvenient for subsequent disassembly and maintenance. Therefore, there is an urgent need for a corrugated pipe connector that is easy to install.

[0025] The locking rod 304 includes a telescopic rod 3041, a spring 3042 movably sleeved on the surface of the telescopic rod 3041, and a beveled locking block 3043 fixedly connected to the bottom of the telescopic rod 3041. By providing a fixed locking ring 2 and a locking rod 304, it is beneficial to move the movable locking sleeve 3 when the bellows body 4 is subsequently disassembled and maintained, so that the locking rod 304 is squeezed into the interior of the movable locking sleeve 3, allowing the bellows body 4 to be quickly separated.
[0026] The connecting sleeve 1 has an annular groove 101 at the position of the movable sleeve fixing lock ring 2, and rectangular grooves 102 are provided on both sides of the surface of the connecting sleeve 1. By providing the fixing lock ring 2 and the locking rod 304, it is convenient to move the movable lock sleeve 3 when the corrugated pipe body 4 is subsequently disassembled and maintained. This allows the fixing lock ring 2 to move the movable lock sleeve 3, so that the locking rod 304 is squeezed into the interior of the movable lock sleeve 3, allowing the corrugated pipe body 4 to be quickly separated.

[0028] The working principle of this utility model:
[0029] First, when preparing to install and connect the corrugated pipe body 4, insert the installation connection groove 401 of the corrugated pipe body 4 into the two sides of the connecting sleeve 1. Then, rotate the fixing locking ring 2, so that the fixing locking ring 2 is restricted to rotate inside the annular slide groove 101 by the annular slide rail 202. At this time, the side threaded plate 203 rotates with the fixing locking ring 2. The rotation of the side threaded plate 203 causes the locking ring 301 to slide in the rectangular slide groove 102 by the locking rod 304 inside the rectangular hole 303. At this time, the spring 3042 on the surface of the telescopic rod 3041 pushes the inclined locking block 3043 away from the inside of the rectangular hole 303, so that the rectangular hole 3041... 3. Enter the installation connection groove 401 opened in the corrugated pipe body 4. At this time, the corrugated pipe body 4 is fixedly connected by the connecting sleeve 1. Then, when the corrugated pipe body 4 needs to be disassembled, the fixing lock ring 2 is rotated in the opposite direction, so that the fixing lock ring 2 drives the movable lock sleeve 3 restricted by the locking rod 304 to approach the position of the fixing lock ring 2. At this time, the inclined side lock block 3043 is squeezed by the edge of the connecting sleeve 1. At this time, the inclined side lock block 3043 pushes the spring 3042 into the rectangular hole 303. After the movable lock sleeve 3 is reset, the corrugated pipe body 4 can be pulled out through the inside of the connecting sleeve 1. At this time, the corrugated pipe body 4 can be disassembled.
