Abstract

The invention discloses a locking assembly of a switching device. The locking assembly comprises a first clamping element (26), a fastening element (36) and an operating element (30). The clamping element is detachably fixed onto an operating shaft (16) of the switching device and can rotate along with the operating shaft; the fastening element is provided with a fastening groove and can move between an unlocking position and a locking position, and the fastening groove can be clamped with the clamping element fixed onto the operating shaft to stop the operating shaft from rotating when the fastening element is located at the locking position; and the operating element is connected with the fastening element, and can be controlled so that the fastening element is driven to move between the unlocking position and the locking position. Only one component is required to be replaced so that the locking assembly with the structure can be mounted in switching devices with various sizes.

Description

technical field [0001] The present invention relates to a lock assembly, in particular to a lock assembly of a switch device, and also to a switch device with the above lock assembly. Background technique [0002] Existing switch devices generally include a handle and an operating shaft fixedly connected to the handle. The handle is rotated between the opening position and the closing position to drive the operating shaft to rotate, thereby controlling the closing and opening of the switching device. Generally, in order to prevent misoperation, a locking device is also designed to lock the handle in the opening position, or lock the handle in the closing position. However, at present, when the locking device is produced, the dimensions of each component need to be designed according to the switch devices of different specifications, which leads to high production cost and difficult processing. Contents of the invention [0003] The object of the present invention is to pr...
