Title:
SHAFT LOCK AND MECHANICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/021737
Kind Code:
A1
Abstract:
A shaft lock and a mechanical device, which relate to the technical field of machinery, and aim to solve the problems in the prior art that the locking of a shaft lock structure is easy to shake due to vacant position and the locking is unstable. The shaft lock is used for locking a first part (50) and a second part (60); the shaft lock comprises a mounting assembly (10), a lock cylinder assembly (20), a locking structure (30) and an elastic assembly (40); the mounting assembly (10) is fixedly connected to the first part (50), the lock cylinder assembly (20) is movably connected to the mounting assembly (10), the locking structure (30) is provided on the second part (60), the locking structure (30) is adapted to the lock cylinder assembly (20), and the elastic assembly (40) is connected to the lock cylinder assembly (20); the elastic assembly (40) drives the lock cylinder assembly (20) to move from the first part (50) in a direction toward the second part (60), or drives the lock cylinder assembly (20) to move away from the second part (60); when the lock cylinder assembly (20) and the locking structure (30) are adapted to each other, the lock cylinder assembly (20) moves from the first part (50) in the direction toward the second part (60), and the longer the moving distance of the lock cylinder assembly (20), the smaller a gap between the lock cylinder assembly (20) and the locking structure (30). By means of the shaft lock, after the first part (50) and the second part (60) are locked, the following beneficial effects can be achieved: the vacant position is smaller, the locking is more stable, and relative shaking is not easy to occur.
