[0002] High-voltage distribution cabinet refers to electrical products with voltage levels ranging from 3.6kV to 550kV, which are used for switching, controlling or protecting the power generation, transmission, distribution, power conversion and consumption of power systems. They mainly include high-voltage circuit breakers, high-voltage disconnectors and earthing switches, high-voltage load switches, high-voltage automatic reclosers and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices and high-voltage switch cabinets. For safety reasons, the electrical cabinets are equipped with door locks.

[0003] The locking shaft of the existing high-voltage electrical cabinet still has some defects. The design of the opening and closing mechanism of most electrical cabinet door locks is relatively complex, resulting in relatively slow and discontinuous opening and locking actions, and a high failure rate, which reduces the overall performance of the electrical cabinet door lock. For this reason, we propose a locking shaft for the high-voltage electrical cabinet. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The control function of the door lock is realized by the button, top block, first spring, first inclined surface, control block, second inclined surface and lock tongue. The structure is simple and not prone to malfunction. It only needs to press the button to drive the control block to move down, thereby driving the lock tongue to squeeze the lock buckle.

[0013] 2. The automatic reset function of the control block is realized by the baffle and the second spring. When the control block moves downward, the second spring is compressed. When the button is released, the control block is reset under the reaction force of the second spring. BRIEF DESCRIPTION OF THE DRAWINGS
