Problems solved by technology
[0003] In the switchgear of power transmission and distribution equipment, it is often necessary to perform locking operations on the opening and closing positions. The existing locking operation handles generally include a handle and an operating end with an operating mechanism. For the pressing cap behind the handle, when operating, press the pressing cap with your hand, and the operating mechanism will unlock to rotate the handle. With the existing structure, since the pressing cap must be pressed and the handle must be rotated during operation, the operation is time-consuming and laborious. Very inconvenient

The invention discloses a switch cabinet mechanical locking handle which comprises a cylindrical shell. An operating rotating shaft is arranged in the shell with the operating end extending out of the shell, a section of guide groove is formed in the circumferential surface of the shell, and an operating rod perpendicular to the operating rotating shaft extends out of the shell from the guide groove and can rotate in a notch of the guide groove to drive the operating rotating shaft to rotate. The portion, extending out of the shell, of the operating rod is sleeved with a lock sleeve which can move back and forth along the operating rod, the periphery of the front end of the lock sleeve is provided with a tapered conical head part, the lock sleeve is further provided with a spring mounting hole, and after a compression spring is installed in the spring mounting hole of the lock sleeve, the conical head part of the lock sleeve is compressed in the guide groove. By the adoption of the structure, the switch cabinet mechanical locking handle is convenient to operate with less effort, high in reliability, reliable in quality and capable of being used in cooperation with a microcomputer lock, operation with ease is achieved, positioning is performed in a one-step mode, and performance is greatly improved.
Description
[0001] technical field [0002] The invention relates to a component used in power transmission and distribution equipment, in particular to a mechanical locking handle of a switch cabinet. Background technique [0003] In the switchgear of power transmission and distribution equipment, it is often necessary to perform locking operations on the opening and closing positions. The existing locking operation handles generally include a handle and an operating end with an operating mechanism. For the pressing cap behind the handle, when operating, press the pressing cap with your hand, and the operating mechanism will unlock to rotate the handle. With the existing structure, since the pressing cap must be pressed and the handle must be rotated during operation, the operation is time-consuming and laborious. Very inconvenient Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a mechanical locking handle of the switchgea...
