Description

Technical Field

[0001] The present application relates to the technical field of locking devices, and in particular to a cage-type locking plate. Background Art

[0002] Currently, in high-speed train designs, much equipment is located in an equipment compartment beneath the train. This compartment is isolated from the passenger compartment and has equipment compartment doors on both sides. While the train is running, the doors are closed. They are opened for routine equipment maintenance. The closing and opening of the doors are controlled by a door lock. When the door lock is closed, the latch engages the strike plate, creating a locked state. At the same time, the strike plate must withstand the load transmitted by the latch. When the door lock is rotated, the latch rotates and disengages from the strike plate, creating an open state. Due to the high speeds and complex equipment of high-speed trains, the strike plate bears significant loads, necessitating a high level of space within the equipment compartment. Conventional strike plates struggle to meet these space and strength requirements.

[0003] Therefore, in order to meet actual needs, a cage-type locking plate is now provided. Summary of the Invention
