Folding type pull-rod movable connecting assembly, folding brake pull-rod and using method of folding type brake pull-rod

Abstract

The invention discloses a folding brake pull-rod movable connecting assembly, a folding brake pull-rod and a using method of the folding brake pull-rod, and belongs to the technical field of power equipment operation tools. The brake pull-rod comprises a first insulating rod and a second insulating rod. The movable connecting assembly comprises a metal locking sleeve, a connecting plate, a firstmagnetic connector which is partially inserted and fixed in the first insulating rod, and a second magnetic connector which is partially inserted and fixed in the second insulating rod. One end of theconnecting plate is hinged with the first magnetic connector; the other end of the connecting plate is hinged with the second magnetic connector; when the brake pull rod is in a folding mode, the metal locking sleeve only sleeves the first insulating rod; when the brake pull rod is in an opening mode, the first insulating rod, the connecting plate and the second insulating rod are located on thesame straight line, the connecting end of the first insulating rod and the second insulating rod is sleeved with the metal locking sleeve in a spaced mode, the two ends of the metal locking sleeve arein magnetic connection with the first magnetic connector and the second magnetic connector respectively, and the movable connecting assembly is convenient to install, good in stability and high in safety.

[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 mainly used for opening and closing of high-voltage isolating switches and drop-out fuses, installation and removal of temporary grounding wires, and discharge Operation and handling of foreign objects on live bodies, as well as high-voltage measurement, testing, operations in direct contact with live bodies, and other operations. The currently used brake levers include fixed and dismountable types. The fixed type is a whole piece. Although it is easy to use, it is not easy to carry. The detachable brake lever is multi-section, and each section is connected by threads. Although it is convenient to carry, it is easy to lose, and it takes a long time to install, especially in the repair work. It takes a lot of time to install. Too fast and easy to damage the thread, resulting in failure to use normally. In the Chinese patent document with the authorized announcement number CN203026381, a foldable switch lever is disclosed. It consists of insulating rod one (1) and insulating rod two (2), connecting the shaft (3), being arranged on the locking buckle (4) between the insulating rod one (1) and the insulating rod two (2), the insulating rod one (1) and the insulating rod two (2) are connected by the connecting shaft (3), Insulation rod one (1) is provided with a connection protrusion (5), insulation rod two (2) is provided with a connection groove (6) matching with insulation rod one (1), and the lock (4) is fixed on the insulation rod At the junction of one (1) and insulating rod two (2), a safety hook (7) is provided on the lock (4)

When using the folding gate lever, straighten the folded gate levers and lock them with the locking device. When not in use, loosen the locks and fold them together, which saves time, is not easy to lose, and has strong stability, but The safety hook of the lock buckle is easy to wear after repeated dismantling, so that the buckle becomes loose and affects the stability of the brake lever. The brake lever is folded and cannot be used normally. At the same time, the brake lever is suddenly folded, and the bent part falls too fast and may hurt the user
