Document Type and Number:
WIPO Patent Application WO/2019/188150
Kind Code:
A1
Abstract:
The present invention pertains to a lock device for a graphite furnace, the lock device being provided with: a fixation part equipped with a lock unit; and a movement part which is set along a first direction so as to face the fixation part and which is equipped with a bolt unit. The movement part moves, in the first direction toward the fixation part, to the bolt unit, and is connected to the lock unit so that the lock device is brought into a lock state. The bolt unit provides, to the movement part, a first biasing force in the direction to the fixation part, and the lock unit releases connection with the bolt unit so that the lock device is brought into a lock release state. The bolt unit provides, to the movement part, a second biasing force in the direction away from the fixation part, and the movement part is separated from the fixation part in the first direction and moves to an initial position while the second biasing force is acting. In the lock device according to the present invention, thermal burns can be prevented because the movement part is automatically elastically separated during the lock release state.
