Description

Junction box fastening wrench

Technical Field

The utility model relates to the field of railway combined transportation, in particular to a wrench.

Background

At present, after the junction box and the cable are preliminarily connected, an operator extrudes a rubber sealing ring into a hole of a certain amount of aluminum alloy studs by the aid of pushing force of hands under the condition that no special tool is available, meanwhile, a locking nut is provided with a threaded buckle of the studs, and finally, the rubber sealing ring is compressed by a fastening nut until the sealing requirement is met. It has the following disadvantages: the hand cannot provide continuous rotary pushing force; the low temperature has great influence on the compression amount of the rubber part; the aluminum alloy threaded fastener has low strength, and the resilience of the initial several fasteners easily causes the threaded fastener to crack; the aluminum alloy studs of the through holes are locked on the junction box body by sealant at one time by manufacturers, and when the aluminum alloy studs are damaged, the EOC junction box is scrapped; the one-time assembly qualification rate cannot be ensured.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a junction box fastening wrench which can provide continuous rotating pushing pressure for a nut in the assembly of a junction box and a cable, thereby avoiding the jumping of an aluminum alloy threaded buckle and avoiding the damage of outsourcing materials under the condition of not increasing the cost.

The utility model mainly comprises a first clamping piece and a second clamping piece.

The clamping device comprises a first clamping piece, a second clamping piece, a connecting hole and a clamping piece, wherein the two ends of the first clamping piece and the two ends of the second clamping piece are both provided with closed surfaces, the closed surface at one end of the first clamping piece and the closed surface at one end of the second clamping piece are both provided with connecting holes, and the closed surface at one end of the first clamping piece and the closed surface at one end of the second clamping piece are rotatably connected. One end of the first clamping piece and the middle part of the inner side of the second clamping piece are provided with semi-conical toothed holes.

In the using process of the utility model, after the junction box and the cable are primarily connected, the junction box is fixed on the bench vice, an operator holds the fastening wrench by hand, the tapered toothed hole of the wrench is meshed with the outside of the locking nut by opening and closing the wrench, and the operator holds the wrench by hand to press two ends of the wrench and rotates the wrench until the nut is fastened to meet the requirements.

Compared with the prior art, the utility model has the following advantages:

(1) providing a continuous rotational biasing force;

(2) unnecessary damage to components caused by external factors and the like is avoided;

(3) the working efficiency is improved.
