Embodiment Construction

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] A kind of tightening handcart crank handle for 35kV handcart switch cabinet, such as figure 1 As shown, it includes a crank 1 and a crank 2 that are rotatably connected. The end of the crank 2 away from the crank 1 is provided with an outer wire sleeve 3 parallel to the crank 1. The crank 1, the crank 2 and the outer wire sleeve 3 are integrally formed. "Z"-shaped structure, easy to rotate with one hand, the operation is more c...

Abstract

The invention discloses a handcart crank handle for 35kV handcart-type switch cabinets that can be tightened, including a crank handle and a crank handle that are rotatably connected. The end of the crank handle facing away from the crank handle is provided with an outer wire sleeve parallel to the crank handle. When the crank handle is rotated, the crank handle will also revolve around the outer thread sleeve while rotating relative to the crank handle, thereby driving the outer thread sleeve to rotate. The outer wire sleeve includes at least two outer wire claws, each of which is elastically connected to the crank. When no external force is applied, the diameter of the free end of the outer wire sleeve formed by the outer wire claws is larger than the diameter of the part near the crank. The threaded connection is provided with an inner wire sleeve, and the inner wall is crimped and fitted with the operating head of the handcart-type switch cabinet. When using, the outer wire sleeve is set on the outside of the operating head, and then the inner wire sleeve is rotated to make the outer wire claw press the outer wall of the operating head. At this time, the operator needs to rotate the crank handle instead of pressing axially at the same time. The invention not only has the advantages of simple structure, quick operation and labor saving, but also shortens the operation time and avoids damage to the personnel of the equipment.

Description

technical field [0001] The invention relates to the technical field of handcart-type switch cabinets, in particular to an elasticated handcart crank handle used in a 35kV handcart-type switch cabinet. Background technique [0002] The handcart-type switch cabinet includes a cabinet body, and an upper door, a middle door and a lower door are arranged in front of the cabinet body; the characteristic is that a detachable baffle is arranged in the cabinet, and the baffle connects the circuit breaker room, The busbar compartment and the cable compartment are separated; the baffle is provided with a hole for inserting the moving contact of the integrated current transformer; the busbar compartment of the cabinet is provided with circuit breakers, transformers, transformers, arresters and other components. The car track is on the ground, far from the static contact of the isolation plug, and the latter handcart track is in the middle of the switch cabinet, which is closer to the st...
