Pulling assisting locker and case bracket and cabinet that use locker

Abstract

The invention relates to the field of locking equipment, particularly to a pulling assisting locker and a case bracket and a cabinet that use the locker. The pulling assisting locker includes a locking base, the front end of the locking base is provided with a fork head, a locking pin shaft is arranged on the fork head, and a pulling assisting supporting structure used for being matched with an outer side face of a lock hook of a corresponding locking piece with the lock hook to assist in outward pulling of a corresponding case is also arranged on the fork head in a position behind the locking pin shaft. In a using process, when locking is needed, an original cooperative relation of the locking piece and the locking pin shaft can be maintained, but when pulling assistance is needed, the pulling assisting supporting structure is matched with the lock hook of the locking piece with the lock hook, thereby forming a fulcrum of the locking piece, and pulling out the case, since a pulling assisting supporting structure pin shaft is arranged separately, the pin shaft is free of restriction of a locking function, and is arranged in an most appropriate position so as to avoid interference, and in general, the pulling assisting locker provided by the invention can be used in cooperation with a handle having the locking piece with the lock hook to realize a pulling assisting function.

Description

technical field [0001] The invention relates to the field of locking devices, in particular to a pull-out locking device, a chassis bracket and a cabinet using the locking device. Background technique [0002] The locking device is a relatively common fixing device, which is widely used on the chassis of airborne instruments and cabinets. [0003] Lockers have different categories according to the actual application environment and application occasions. For example, the swing lock disclosed in the Chinese patent specification with the publication number CN201162757Y and the anti-loosening lock for aviation disclosed in the Chinese patent application specification with the publication number CN103062169A are two different types of locks respectively. [0004] In addition to the lockers disclosed in the above patent specification or patent application specification, there is also a more commonly used locker in the prior art, that is, a B-type locker. [0005] Type B locking...

AI Technical Summary

Problems solved by technology

[0006] In the actual application process, not all the B-type handles produced by electronic equipment manufacturers are standard handles. , the handle locking part will lock the pin shaft of the locking device in the hook shape of the locking part, and the pull-out function cannot be realized

E.g image 3 As shown in the handle, the lower end of the locking member 61 is provided with a locking hook 62. If the traditional standard B-type locking device is still used, the locking hook will interfere with the pin shaft, which will eventually lead to the failure of the extraction.
