Description

Switch storage spring remover

technical field

The utility model patent relates to a disassembler, in particular to a switch energy storage spring disassembler.

Background technique

In the prior art, when disassembling and assembling the energy storage spring of the circuit breaker, the spring needs to be stretched before disassembling and assembling. The current general method is to force the spring to stretch by inserting several large screwdrivers into the spring gap. This method seems simple, but excessive force or instability during the process may cause spring deformation and damage. After inserting the screwdriver into the gap, you have to pay attention to the danger that the screwdriver may fly out of the gap. The whole process is time-consuming and laborious and also poses a certain safety hazard.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a switch energy storage spring disassembler with reasonable structure, easy assembly, convenient transportation, low cost and wide application range.

In order to achieve the above purpose, the utility model adopts the following technical solutions: the switch energy storage spring disassembler includes a main rod, an active part, a screw and a buckle plate, and the two ends of the main rod are provided with external threads in opposite directions; There are two active parts, which are respectively matched with the external threads of the two ends of the main rod; the active part is connected with the lower pinch plate, and the upper pinch plate is matched with the lower pinch plate; the upper pinch plate and the lower pinch plate The board is composed of two semicircular gussets and fixed by screws.

As a preference: both the main rod and the active part are made of fine steel.

As a preference: one end of the main rod is provided with an outer hexagonal end.

The beneficial effect of the utility model is that the manufacturing cost of the device is not high, and the transportation is very convenient because it can be disassembled. The structure is simple, non-professionals can assemble without problem, and it is safe and reliable. It is applicable to energy storage springs of various sizes and has a wide application range.

detailed description

Below in conjunction with embodiment the utility model is described further. The description of the following embodiments is only used to help understand the utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made to the utility model, and these improvements and modifications also fall into the protection of the claims of the utility model. within range.

Referring to Fig. 1, this switch energy storage spring remover includes a main rod 1, an active part 2, a screw 3 and a buckle plate 4, and the two ends of the main rod 1 are provided with external threads in opposite directions; the active part 2 There are two, which are respectively matched with the external threads of the two ends of the main rod 1; the active part 2 is connected with the lower pinch plate 5, and the upper pinch plate 4 is matched with the lower pinch plate 5; the upper pinch plate 4 and the The lower gusset 5 is composed of two semicircular gussets and fixed by screws 3 . Both the main rod 1 and the active part 2 are made of fine steel. One end of the main rod 1 is provided with an outer hexagonal end.

The utility model is mainly buckled on the energy storage spring through the upper pinch plate 4 and the lower pinch plate 5, and then the two sections of the upper pinch plate 4 and the lower pinch plate 5 are separated by rotating the main rod 1 to stretch the spring, so that the force of spring contraction Beared by the upper pinch plate 4 and the lower pinch plate 5, the positioning shafts at both ends of the spring can be removed or installed.

The utility model uses steps as follows:

(1) First adjust the distance between the buckle plates according to the spring specification, buckle the upper buckle plate 4 and the lower buckle plate 5 on the energy storage spring, and tighten the screw 3 to fix the spring.

(2) Turn the main rod 1 to separate the two sections of the upper pinch plate 4 and the lower pinch plate 5, so that the spring is stretched.

(3) Disassemble the spring positioning shaft.
