The invention relates to a high-voltage self-locking brake pull-rod quick connecting piece. The high-voltage self-locking brake pull-rod quick connecting piece comprises a first pipeline, a first connecting pipe, a limiting pipe, a second pipeline, a second connecting pipe, a locking sleeve, an unlocking pipe and a plurality of locking balls. The locking balls are matched with the locking sleeve, the second connecting pipe is fixed to the designated position, connection of the first pipeline and the second pipeline is quickly and efficiently completed, meanwhile, the situation that the connecting position is loosened due to the fact that a brake pull-rod is frequently used for a long time is effectively avoided, and while the connection stability is guaranteed, the service life of the connecting piece is effectively prolonged, and the use efficiency of the brake pull-rod using the connecting piece is effectively improved; and by reducing the diameter of the end portion of a through groove, the situation that the second connecting pipe cannot be locked by the subsequent first connecting pipe due to the fact that the locking bead falls off from the inner wall of the first connecting pipe when the second connecting pipe is not locked by the first connecting pipe can be effectively prevented, and the use efficiency of the brake pull-rod using the connecting piece is further improved.
Description
technical field [0001] The invention relates to the technical field of brake rod connection, in particular to a high-pressure self-locking brake rod quick connector. Background technique [0002] Pulling lever, also known as insulating operating rod, insulating rod, high-voltage operating rod, commonly known as multi-purpose gram rod, high-voltage switching rod is an insulating tool used to operate live equipment in a short time, mainly used for high-voltage isolating switches and drop-off switches. The opening and closing of fuses, installation and removal of temporary grounding wires, discharge operations, handling of foreign objects on live bodies, as well as high-voltage measurement, testing, and operations in direct contact with live bodies. The current use of the brake lever includes fixing Type and detachable type, the fixed one is a whole piece, although it is convenient to use, but it is not easy to carry, the detachable one is multi-section type, and each section i...
