Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated power pipes, in particular to a high-strength MPP rotary corrugated power pipe. Background Art

[0002] Corrugated power pipes are mainly used to cover power transmission lines, and they protect power transmission lines in complex environments. Since they are in complex environments for a long time, power corrugated pipes are required to have corresponding structural bearing capacity to prevent the wires inside from being damaged or even torn due to stress.

[0003] The existing corrugated power pipe is inconvenient to splice in actual use, mainly because the two ends of the power corrugated pipe are relatively smooth, and the actual combination connection needs to contact other connectors, which makes it inconvenient to connect the corrugated power pipe.

[0004] Based on this, we propose the high-strength MPP rotary corrugated power tube. Utility Model Content

[0012] With the above structure, the volute spring is arranged to conveniently and directly drive the pressing plate to be pressed in the arc groove.

[0013] A telescopic rod is fixedly connected to an inner wall of one side of the locking seat, and a spring is sleeved on an outer wall of the telescopic rod.

[0014] With the above structure, the arrangement of the telescopic rod makes it convenient to install and fix the spring.

[0015] The outer wall of the telescopic rod is rotatably connected with a connecting plate, and one end of the connecting plate is rotatably connected to the pressing plate.

[0016] With the above structure, the telescopic rod and the pressing plate are connected via the connecting plate, so that the pressing plate can be directly driven to move when the telescopic rod moves.

[0032] In this embodiment, through the cooperation between the female head 2 and the male head component 3, it is convenient to assemble two or more high-strength MPP corrugated power tubes. The cooperation between the two locking mechanisms 7 in the male head component 3 and the slide groove 18 and the arc groove 10 in the female head 2 facilitates the male head component 3 to be directly fixed in the female head 2.

[0033] The locking mechanism 7 comprises a locking seat 11 fixedly connected to the connecting sleeve 4 , and an opening is formed on one outer wall of the locking seat 11 , and a pressing plate 12 is rotatably connected to the inner wall of the opening.

[0034] In this embodiment, an adjustable pressing plate 12 is provided on the locking seat 11 , thereby facilitating the fixing of the locking seat 11 in the arc-shaped groove 10 .
