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 modular electrical cabinets, in particular to a torque-limiting booster lock for a chassis. The booster lock includes a lock rod and a lock cap. The front end of the lock cap is provided with a lock port for matching with a locking hook on the chassis. The lock rod is threaded with a screw sleeve, and the screw sleeve is also equipped with a force-limiting spring, a pressure Plate, transmission plate, rotatable screw cap and output sleeve, there is a baffle wall between the two ends of the screw cap, the baffle wall is provided with a transparent mounting hole, and a transmission steel ball is assembled in the mounting hole, and the pressing plate and The transmission piece is arranged on both sides of the baffle wall, wherein the transmission piece is matched with the screw sleeve to prevent rotation and is provided with a ball groove corresponding to the steel ball, and the force-limiting spring top is installed between the side of the pressing piece away from the steel ball and the screw sleeve , the output sleeve is provided with a locking hook pushing structure for cooperating with the locking hook on the corresponding chassis to push the chassis, and the screw sleeve is provided with a transmission structure for driving the output sleeve to move forward, the invention solves the problem of the existing lock The problem of poor booster's boosting ability and unlimited boosting force.

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...
