Problems solved by technology

[0003] However, due to the structural characteristics of traditional composite locking devices, especially structural parts similar to cylinders and round pipes, it is difficult to fix and lock them well and prevent them from rotating without changing the structure of the original parts.
Especially in the case of severe vibration, the fixed locking and anti-rotation capabilities of general locking devices are weaker, and most locking devices have complex structures, inconvenient operations, and poor anti-loosening performance

Abstract

The invention provides a composite locking device, comprising: a base (1), a long connecting rod (2), a middle connecting rod (3), a short connecting rod (4) and a hook rod (15); The rod (3) and the short connecting rod (4) are respectively connected to the base (1); the long connecting rod (2) is connected to the middle connecting rod (3); the hook rod (15) is connected to the long connecting rod (2) connection; the middle connecting rod (3) is provided with a first sliding head (9); the short connecting rod (4) is provided with a second sliding head (10). Under the condition of keeping the operation steps unchanged, the present invention can simultaneously realize the radial and axial locking of the fixed structural parts, effectively avoid the problem of local loosening of the fixed structural parts, and make the fixed structural parts adaptable to various vibration occasions and There will be no looseness.

Description

technical field [0001] The present invention relates to the field of mechanical locking devices, in particular to a compound locking device, especially a compound locking device of a cylindrical or similar cylindrical structure. Background technique [0002] A traditional rack compound locking device as disclosed in patent document CN201342578Y includes a locking seat, a locking cylinder, a piston, and a disc spring. The piston and a V-shaped seal are installed in the locking cylinder, and the locking cylinder is connected In the middle of the locking seat, one side of the locking seat is provided with a boss, and the two sides of the locking seat are equipped with screw rods that pass through the locking seat. The lower end of the screw rod is equipped with a disc spring and is fixed with a nut. On the frame, an adjusting screw is provided on the locking seat passing through the side of the boss, and the threaded end of the adjusting screw is in contact with the frame, and ...
