Abstract

The invention relates to the field of cabinet locking equipment and especially relate to an anti-loose locker and a cabinet carriage and a rack using the same locker. The anti-loose locker comprises a locker pedestal and a locking member. The locking member is provided with a locking pin shaft. The locking pin shaft comprises a rear surface used for adapting to a latch hook for hooking. The locking member is in guiding slide cooperation with the locker pedestal in a front-back direction through a connection part, and an elastic piece used for providing backward elastic force to the locking member is arranged between the locking member and the locker pedestal. The elastic piece is arranged between the locking member and the locker pedestal, so that the elastic force is generated between the locking member and the locker pedestal, and provides pretightening force in locking so as to eliminate a contact gap between the locking member and the locker pedestal, so that a carriage is prevented from loosing and influencing the locking effect of a cabinet.

Description

technical field [0001] The invention relates to the field of case locking equipment, in particular to an anti-loosening locker and a case bracket and a cabinet using the locker. Background technique [0002] The airborne equipment in the aviation field generally adopts a modular chassis structure, and the chassis is fixed in the corresponding equipment compartment. In order to make it have a certain impact resistance and vibration resistance, it is often reinforced with corresponding components. The locking device is the most commonly used component for fixing the airborne equipment chassis at present. [0003] For example, the Chinese patent whose application publication number is CN 104883851 A and whose publication date is 2015.09.02 discloses a pull-out locking device and a chassis bracket and a cabinet using the locking device. The locking device belongs to the class B lock The locking device includes a locking device base, the fork is fixedly assembled on the front en...
