Combined type locking device

Abstract

The invention provides a combined type locking device. The combined type locking device comprises a bottom seat (1), a long connection rod (2), a moderate connection rod (3), a short connection rod (4) and a hook rod (15), wherein the moderate connection rod (3) and the short connection rod (4) are respectively connected with the bottom seat (1), the long connection rod (2) is connected with the moderate connection rod (3), the hook rod (15) is connected with the long connection rod (2), a first sliding head (9) is arranged on the moderate connection rod (3), and a second sliding head (10) isarranged on the short connection rod (4). The combined type locking device can synchronously realize locking of a fixed structural member in the radial direction and the axial direction on the premiseof keeping operation steps unchanged, effectively avoids the problem that the fixed structural member is locally loosened, enables the fixed structural member to adapt to various vibration occasions,and prevents a loosening phenomenon from occurring.

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 ...

AI Technical Summary

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
