A locking device and a fixed-node robot

Abstract

The present disclosure provides a locking device and a fixed-node robot, comprising: a lock case, a rocker arm and a contact arm, the rocker arm and the contact arm are both arranged in the lock case, and in the lock case There is a locked state and an unlocked state inside; the connecting rod has a long strip-shaped through hole, and the rocker arm is slidably arranged in the long strip-shaped through hole; the push rod is connected with the rocker arm and is at least partially arranged on the Outside the lock housing, the rocker arm can be pushed to slide in the elongated through hole to break away from the locked state; the actuator, connected to the connecting rod, can drive the connecting rod to move along its extending direction , so that the rocker arm is out of the locked state. The present disclosure can avoid the phenomenon of mis-opening under the condition of relatively large impact force.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the technical field of firefighting, and more specifically, relate to a locking device and a fixed-node robot. Background technique [0002] At present, an electromagnet is used as the actuator in the opening switch of the robot. When the electromagnet is inactive, the magnetic core is kept at the initial position by the pressure of a coil spring. When the electromagnet is energized and closed, the magnetic core Overcome the spring pressure and move from the initial position to the end position, and the distance from the initial position to the end position is the action execution distance. [0003] One end of the magnetic core is connected to the switch structure. When the electromagnet is energized, the magnetic core compression spring moves from the initial position to the final position, and the magnetic core will drive the switch to open. When the electromagnet is powered off, the magnetic...

Problems solved by technology

[0004] This kind of electromagnet has a defect in use and cannot be used in the occasion where the inertial force acts. Since the magnetic core of the electromagnet only relies on the elastic force of a coil spring to keep it in the initial position, the elastic force of the spring is very limited. , when the electromagnet receives a relatively large momentary impact such as a collision, the core of the electromagnet can easily overcome the elastic force of the spring under the action of inertial force, causing the switch to be opened by mistake
