Abstract

The invention provides a locking device and mainly solves the difficult detachment and low reliability problems of the traditional locking device. The locking device comprises a threaded rod, a lock catch and a lock wheel, wherein the lock wheel consists of a threaded sleeve, a lock wheel retainer ring, a spring and a lock sleeve; one end of the threaded rod is provided with a fixed hole fixed with equipment, while the other end is provided with the lock wheel retainer ring to prevent the lock wheel from falling off; the lock catch and the lock wheel are both provided with sawteeth; and the lock catch sawteeth are meshed with the lock wheel sawteeth to prevent looseness caused by factors such as shock impact. When the locking device is unlocked for maintenance and replacement, a longitudinal force along the direction of the central axis of the threaded rod can be applied to unlock the sawtooth-meshed parts; and therefore, the locking device is simple in operation and avoids the use of tools.

Description

technical field [0001] The invention relates to a locking device, in particular to a high-strength fast locking and disengaging locking device. Background technique [0002] For equipment that works in a more complex environment, especially equipment that often moves or generates vibrations, such as electronic equipment and precision instruments installed on airplanes and trains, it is necessary to fix the working position to ensure that the equipment is not affected by vibration and inertia. Factors such as location changes affect performance. Because the change of the working position may lead to failure, damage to the circuit, and even the destruction of the entire device or system in severe cases. [0003] While ensuring that the position is fixed, this type of equipment also needs to be easy to disassemble, so that the staff can perform security inspection, maintenance, and replacement of the fixed equipment. [0004] At present, for the fixing of this type of equipme...
