Description

Technical Field

[0001] The utility model belongs to the technical field of shunts, in particular to an alloy shunt which does not require resistance repair. Background Art

[0002] The shunt is actually a low-value resistor. The shunt is used to measure current. It is made based on the principle that voltage is generated across the resistor when DC current passes through it. It can pass large currents through precise resistors. When current flows through the shunt, when DC current passes through, a voltage drop is generated, which is displayed by the DC ammeter.

[0003] Currently, alloy shunts that do not require repair are mostly fixed by bolts. However, when the bolts are disassembled for repair, they may be thread-slipped, making it impossible to fix them accurately, resulting in poor use effect.

[0004] For example, a shunt in the prior art Chinese patent document (application announcement number CN209647839U) has a resistance adjustment slot added to the resistor plate to facilitate the shunt resistance adjustment, and the resistance adjustment is simple. At the same time, two first flat pads or connecting columns are set at the first through hole to ensure the stability of the resistance value of the shunt after the connection circuit when in use. The processing technology is simple, the material is small, the quality is small, and the yield rate is high. The prior art has the following problem: it is mostly fixed by bolts, but when disassembling and repairing, the bolts will have slipped threads, resulting in inaccurate fixation, resulting in poor use effect.

[0005] Therefore, in view of this situation, there is an urgent need to design and produce alloy shunts that do not require resistance repair to meet the needs of practical use. Utility Model Content

[0006] The utility model aims to provide an alloy shunt which does not require resistance repair, so as to solve the problems raised in the background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an alloy diverter that does not require resistance repair, comprising an alloy diverter body used as an alloy diverter that does not require resistance repair, a first clamping block is clamped on the side of the alloy diverter body, an end of the first clamping block away from the alloy diverter body is fixedly connected to a limiting plate, a base is provided on the lower side of the alloy diverter body, a second clamping block is clamped on the side of the first clamping block, an end of the second clamping block away from the first clamping block is fixedly connected to a second rack slidably connected to the base, and a side of the second rack is meshed with a circular gear rotatably connected to the base.

[0008] Preferably, a first rack slidably connected to the base is meshed on the side of the circular gear, and a third return spring is welded to one end of the second rack away from the second clamping block.

[0009] Preferably, the third return spring is welded to the inside of the base, and the second return spring is welded to the side of the first rack.

[0010] Preferably, the second return spring is welded to the inside of the base, and a pressing block is welded to one end of the first rack away from the second return spring.

[0011] Preferably, a first limiting block is clamped on the side of the pressing block, and a connecting block with a hexagonal cross-section is installed on the upper side of the base.

[0012] Preferably, the bottom side of the first limiting block is clamped with the second limiting block having a hexagonal groove, and a first return spring is welded inside the base.

[0013] Preferably, a first fixing plate slidably connected to the base is welded to a side of the first return spring, and the second limiting block is clamped with the connecting block.

[0014] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0015] The alloy diverter without repair resistance drives the first rack to move downward by squeezing the pressing block, drives the circular gear to rotate, drives the second rack and the second clamping block to move by the rotation of the circular gear, and clamps the first clamping block to the alloy diverter body. The pressing block is released, and the second reset spring extends upward to drive the first rack to move upward, drives the circular gear to rotate, drives the second rack and the second clamping block to move, clamps and fixes the first clamping block, and then clamps the first limit block and the pressing block, so that it is not necessary to screw and fix by bolts, avoids thread slippage, and makes the fixation more stable.

[0016] At the same time, the first return spring blocks and pushes the first fixing plate to move, thereby fixing the alloy diverter body. BRIEF DESCRIPTION OF THE DRAWINGS
