Document Type and Number:
WIPO Patent Application WO/2023/274348
Kind Code:
A1
Abstract:
Provided is a lock device, comprising a lock latch (5) and at least two brake blocks (4). The lock latch (5) is provided with at least two brake parts. The brake parts on the lock latch (5) are provided corresponding to the brake blocks (4). Each brake block (4) is connected to a linkage member. The linkage member can drive each brake block (4) to rotate, so that the brake block (4) is abutted against or is separated from the brake part on the lock latch (5). The brake parts are symmetrically arranged on both ends of the lock latch (5) in the lock device. When the lock latch (5) is locked, the brake parts arranged on both ends of the lock latch (5) are in contact with a main shaft (6). The lock latch (5) is uniformly stressed, and is not distorted and deformed, so that the service life of the lock device is prolonged. The lock device can be used in different stress environments, so that the application range of the lock device is expanded. The lock latch (5) stressed on two sides can withstand a large dynamic impact test.
