Description

Technical Field

[0001] The invention relates to the technical field of remote operating mechanisms for low-voltage electrical appliances, in particular to a flexible external cabinet operating mechanism for low-voltage electrical appliances. Background Art

[0002] At present, the external mechanisms of low-voltage electrical appliances are all connected by rigid shafts. For electrical cabinets that use external low-voltage electrical appliances, the center of the external mechanism and the center of the low-voltage electrical appliance operating shaft must be concentric to ensure smooth opening and closing of the cabinet door. If the external mechanism is too concentric or the opening center is eccentric, the cabinet door cannot be opened and closed smoothly.

[0003] In addition, the position of low-voltage electrical appliances in the cabinet is limited by the electrical layout, and the position may be too high or too low. The current rigid shaft connection method also limits the position outside the cabinet to be concentric with the center of the low-voltage electrical appliance operating axis. Therefore, sometimes the operating position outside the cabinet is too high or too low, which is not conducive to the operator to perform operations outside the cabinet. Summary of the invention
