Connecting device

Abstract

The invention relates to the technical field of power equipment maintenance tools, in particular to a connecting device which comprises a chuck base and a sliding block, a static chuck is arranged atthe upper end of the chuck base, a guide hole is formed in the lower end of the chuck base, the sliding block penetrates through the guide hole and can slide in the guide hole in a reciprocating mode,the upper end of the sliding block is connected with a movable chuck, and the movable chuck and the static chuck can be matched to clamp an object. A through hole is formed in the sliding block in the axial direction, a screw rod is arranged in the through hole, the upper end of the screw rod is rotatably connected with the sliding block, a locking key is hinged to the side wall of the chuck base, locking threads are arranged on the side, facing the screw rod, of the upper end of the locking key, and a locking key spring is arranged between the lower end of the locking key and the chuck base.Therefore, the locking thread of the locking key deflects towards the screw rod in a natural state and is in threaded engagement with the screw rod; and the connecting device is convenient to operate, firm and reliable in connection, capable of greatly shortening the operation time for connecting or loosening the clamped object, simple and small in structure and suitable for construction in a narrow space.

Description

technical field [0001] The invention relates to the technical field of power equipment maintenance tools, in particular to a connection device. Background technique [0002] In recent years, people have higher and higher requirements for the reliability of power supply. Power companies are using various methods to shorten construction and emergency repair time to ensure continuous power supply to customers. In power system construction, connecting devices are often used to repair conductors or wiring There are two main types of connection devices commonly used at present: screw compression type and spring compression type, each of which has its own advantages and disadvantages. The screw-type contact surface is fastened and reliable, but the operation time is long. The spring compression type greatly shortens the operation time, but due to the aging and damage of the spring, there will be problems that the contact surface is not fastened and reliable. Therefore, at present...

Problems solved by technology

The spring compression type greatly shortens the operation time, but due to the aging and damage of the spring, there will be problems that the contact surface is not fastened and reliable

Therefore, at present, many connection devices adopt the screw compression type, but this method uses the operator to rotate the insulating rod, so that the wire clamp part of the connection device moves upward with the bolt to clamp the wire. 8CM, whether it is the operation process of tightening the wire clamp to clamp the wire or the operation process of unscrewing the wire clamp to exit the wire, the time of rotating tightening or loosening is too long, and more than half of the row distance is invalid stroke, which leads to the use of screw The labor intensity of the maintenance operators of the compression connection device is strong, it is very inconvenient, the assembly and disassembly efficiency is low, and time-consuming and laborious
