Outer one-way adjustable telescopic corrugated pipe

Abstract

The invention discloses an external one-way adjustable telescopic bellows, comprising a first fixing piece and a second fixing piece, a telescopic bellows device is arranged between the first fixing piece and the second fixing piece, and the telescopic bellows The pipe device includes a bellows, a limit piece, a transmission bearing and a transmission rod. The body of the bellows is provided with a limit piece, and the edge of the limit piece is provided with a third fixed ear extending outward. The third fixed lug is provided with a second shaft hole, and both sides of the second shaft hole are provided with second fixed holes, and the transmission bearing is matched with the first shaft hole and the second shaft hole respectively, The transmission rod is installed in the transmission bearing, and one end of the transmission rod is connected with the screw hole; the present invention aims to provide an external one-way adjustable telescopic bellows with high safety, convenient transportation, telescopic and dislocation installation. Tube.

Description

technical field [0001] The present invention relates to the technical field of corrugated pipes, in particular to the external one-way adjustable telescopic corrugated pipes. Background technique [0002] Traditional straight bypass pipes are mostly used for temporary connection of pipelines during pipeline maintenance, while pipelines are disconnected during maintenance, the distance between the two pipes is unpredictable, and the center of the pipe hole is also unclear Whether it is aligned or not, the maintenance personnel must carry the straight bypass pipes of various sizes on the car and transport them to the emergency repair place before going out for maintenance. Due to the heavy weight of these bypass pipes, the moving process is laborious and laborious, which will increase the number of maintenance personnel The work is difficult, and the quantity is large, taking up a lot of space, and transportation is troublesome. [0003] If a metal expansion joint is used ins...

[0002] Traditional straight bypass pipes are mostly used for temporary connection of pipelines during pipeline maintenance, while pipelines are disconnected during maintenance, the distance between the two pipes is unpredictable, and the center of the pipe hole is also unclear Whether it is aligned or not, the maintenance personnel must carry the straight bypass pipes of various sizes on the car and transport them to the emergency repair place before going out for maintenance. Due to the heavy weight of these bypass pipes, the moving process is laborious and laborious, which will increase the number of maintenance personnel The work is difficult, and the quantity is large, taking up a lot of space, and transportation is troublesome

[0003] If a metal expansion joint is used instead of a straight bypass pipe in the maintenance process, although the distance between the two pipes can be solved, the weight of the metal expansion joint is also relatively large, it is troublesome to use and adjust, and it cannot be misplaced; use stainless steel bellows When replacing the straight bypass pipe, although the stainless steel bellows has good flexibility and can be used in misplaced positions, its cost is high, and it is easy to deform seriously after being compressed, so the safety cannot be guaranteed
