Embodiment Construction

[0024] Examples of torque-limiting booster locks for chassis, such as Figure 2-12 As shown, the booster lock includes a lock rod 11, a screw sleeve 12, a screw cap 13, a transmission steel ball 14, a transmission piece 15, a pressing piece 16, a force limiting spring 17, a spring support sleeve 18, an output sleeve 19, a transmission Seat 20, ball 21, pushing spring 22, drive sleeve 23, lock cap 24 and lock seat 25.

[0025] The front end of the locking rod 11 is provided with a hinge hole and a threaded section is provided between the two ends.

[0026] The position between the two ends of the screw sleeve 12 is provided with an internal thread segment, which corresponds to the thread segment on the lock bar 11, and the screw sleeve 12 is exactly through the connection between its internal thread segment and the thread segment of the lock bar 11. Cooperate and threadedly assembled on the lock rod 11, because both of them are not all provided with threads, so the rear end of...

Abstract

The invention relates to the field of modularized electrical cabinet, and in particular relates to a torque-limiting boosting locker for a case. The boosting locker includes a lock rod and a lock cap, wherein a lock opening matched with a lock hook on the caser is arranged at the front end of the lock cap; a thread sleeve is assembled on the lock rod in a threaded manner; a force-limiting spring, a press plate, a transmission plate, a rotary turncap and an output sleeve are also assembled on the thread sleeve; a baffle wall is arranged between two ends of the turncap, and provided with a installing through hole in which a transmission steel ball is assembled; the press plate and the transmission plate are respectively arranged on two sides of the baffle wall; the transmission plate is matched with the thread sleeve and provided with a ball groove corresponding to the steel ball; the force-limiting spring is propped between one side, away from the steel ball, of the press plate and the thread sleeve; the output sleeve is provided with a lock hook push-press structure matched with the lock hook on the corresponding case for pushing the case; the thread sleeve is provided with a transmission structure for driving the output sleeve to move forwards. The torque-limiting boosting locker overcomes the problems that the existing locker is poor in boosting capability, and cannot limit force in boosting.

Description

technical field [0001] The invention relates to the field of modular electrical cabinets, in particular to a torque-limiting booster locker for a cabinet. Background technique [0002] With the development of modularization and miniaturization of various electronic equipment, electronic equipment cabinets have been widely used in electronic equipment cabinets (electrical cabinets). In the specific use process, in order to realize the overall loading, unloading and replacement, the electronic equipment chassis is introduced through the electrical connector provided at the rear end and the adapter connector provided in the cabinet to realize the introduction of the electronic equipment chassis. It is required that the electronic equipment case must have a reliable fixing mechanism when it is assembled on the cabinet. [0003] figure 1 Shown is a common locking device used for locking electronic equipment chassis in the prior art. The locking device includes a lock base 51, a...
