The invention discloses a locking device, which includes a main body, a slide block and a locking assembly. A locking groove for accommodating a switch block is recessed on the abutment plane of the main body. The locking groove has a first groove wall and a second groove wall opposite to each other. , a guide hole is opened on the second groove wall, and the installation groove in the main body communicates with the locking groove through the guide hole. , the end of the slider extending into the locking groove can press the switch block against the first groove wall, when the slider moves to the unlocked position, the slider is separated from the switch block, and the locking component is connected with the slider, which can Lock the slider in the locked position. By setting the slider and the locking component, moving the slider can press the switch block tightly, and operating the locking component can lock the slider in the locked position to prevent the slider from moving, thereby ensuring that the switch block is locked in place In the locking groove of the locking device, the switch block can be effectively prevented from being arbitrarily moved to improve safety.
Description
technical field [0001] The invention relates to the technical field of switchgear, in particular to a locking device. Background technique [0002] At present, in the maintenance process of elevators and other equipment, maintenance personnel need to disconnect the working circuit in advance, and toggle the dial of the main switch of the working circuit to the disconnected position (the main switch has a disconnected position and a closed position) during operation, so that Provide a safe and reliable working environment for maintenance personnel. However, if there is no warning sign or locking device at the main switch, once other workers close the circuit without knowing it, it is likely to cause danger, even casualties, and there is a very large safety hazard. [0003] At present, there are mainly two types of warning structures set at the main switch: the first is to set up a signboard, which is hung on the main switch with a nylon rope, or temporarily fixed with insula...
