Testing wire instrument having multi-wire winding and unwinding functions and high stability

Abstract

The invention discloses a testing wire instrument having multi-wire winding and unwinding functions and high stability. The testing wire instrument comprises a rotating shaft, a shaft bracket fixatorand a housing; the shaft bracket fixator is arranged at one end of the rotating shaft in an embedded manner and is movably connected with the rotating shaft; the housing is arranged on one side of theshaft bracket fixator; the housing and the shaft bracket fixator are welded; a gear column is arranged on one side of the rotating shaft; the gear column is arranged at the side wall of the rotatingshaft in an embedded manner and is in interference fit with the rotating shaft; and a wire winding disc is arranged on one side of the gear column, is arranged at the side wall of the gear column in an embedded manner and is engaged with the gear column through a gear. The testing wire instrument is provided with the rotating shaft as a core rotating component, the rotating shaft can brake the wire winding disc in the wire winding process by the cooperation of a crank handle and a handle shaft, and the testing wire instrument is overhead entirely, so that the wire winding efficiency is improved advantageously; and the housing acts as a supporting depending assembly, so that wire winding and unwinding are free without excessive constraint, and simple operation of the wire winding and unwinding is realized.

Description

technical field [0001] The invention relates to the technical field of wire take-ups, in particular to a test wire take-up and high stability of multi-wire retraction. Background technique [0002] With the current rapid development and the popularization and expansion of electric power, the industrial life is much more convenient, and the wire as the carrier of power transmission has become an indispensable tool. When in use, the wire is often stored in a reel for easy carrying and use. [0003] However, the current take-ups have the following defects: one is that the existing take-ups are bulky and unfavorable for carrying. Single-wire coiling is possible, that is, only one wire can be used each time, which prevents workers from carrying multiple wire take-ups to distinguish between electric types. Three existing wire take-ups should be manually coiled so that It does not have a brake, and the brake is a key component for the stability of the solid wire take-up and pay-of...

[0003] However, the current take-ups have the following defects: one is that the existing take-ups are bulky and unfavorable for carrying. Single-wire coiling is possible, that is, only one wire can be used each time, which prevents workers from carrying multiple wire take-ups to distinguish between electric types. Three existing wire take-ups should be manually coiled so that There is no brake, and the brake is a key component for the stability of the solid wire take-up and pay-off. Without a brake, the stop of the wire take-up is uncontrollable when the equipment is in use. The stop during the take-up process needs to be controlled
