Description

Technical Field

[0001] The utility model relates to the technical field of circuit breaker production, in particular to an installation tool for a moving contact mechanism of a circuit breaker. Background Art

[0002] A circuit breaker is a switching device that can close, carry and interrupt current under normal circuit conditions. It is an important component of the moving contact mechanism circuit breaker.

[0003] like Figure 4 As shown, in the prior art, the moving contact mechanism includes a moving bracket 101, a spring 105 installed inside the moving bracket 101, a rotating groove 103 provided on the inner wall of the moving bracket 101, a rotating shaft 102 rotatably installed in the rotating groove 103, and a moving contact 104 provided on the rotating shaft 102. When installing the moving contact mechanism, the rotating shaft 102 needs to be inserted into the rotating groove 103. During this process, the rotating shaft 102 will compress the spring 105. However, it is difficult to directly compress the spring 105 with the strength of the hand, so a manual press is used for assistance. However, during the pressing process, since the moving contact mechanism is directly placed on the manual press, the moving contact mechanism will be offset, resulting in a pressing failure. Multiple attempts are often required, and the installation efficiency is extremely low. In addition, the pressure head of the manual press is difficult to align with the moving contact 104, and it is easy to press the wrong position, thereby causing damage to the moving contact mechanism and affecting its quality. Utility Model Content

[0004] The purpose of the utility model is to provide an installation tool for a moving contact mechanism of a circuit breaker to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an installation tool for a moving contact mechanism of a circuit breaker, comprising a manual press and a positioning tool movably placed on the manual press, a positioning groove being provided on the top of the positioning tool, a plurality of slots being provided inside the positioning tool, and a plurality of the slots being connected to the positioning groove, and a limiting block being fixedly connected to the top of the positioning tool.

[0006] As a preferred solution of the utility model, a stopper for blocking the positioning tooling is fixedly installed on the manual press.

[0007] As a preferred solution of the utility model, a protrusion is provided on one side of the stopper, and a groove matching with the protrusion is provided on the side of the positioning tool close to the stopper.

[0008] As a preferred solution of the utility model, the stopper is fixed to the manual press by screws.

[0009] As a preferred solution of the utility model, the positioning fixture and the stopper are both made of steel.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model can limit the moving contact mechanism through the positioning tooling, limit blocks, slots and positioning grooves to prevent it from shifting, and then the rotating shaft can be easily pressed into the rotating groove by using a manual press, which greatly improves the installation efficiency and does not cause damage to the moving contact mechanism, thereby ensuring the quality of the moving contact mechanism. At the same time, the positioning tooling can be blocked by the set block, thereby positioning the moving contact mechanism placed on the positioning tooling, making it easier for the pressure head of the manual press to align with the moving contact mechanism.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1 to 4The utility model provides a technical solution: an installation tool for a moving contact mechanism of a circuit breaker, comprising a manual press 1, and a positioning tool 2 movably placed on the manual press 1, a positioning groove 4 is provided on the top of the positioning tool 2, the positioning groove 4 is adapted to the moving contact mechanism, and the moving contact mechanism can be inserted into the positioning groove 4, thereby limiting the moving contact mechanism to prevent it from deflecting, and then the manual press 1 can be used to easily press the rotating shaft 102 into the rotating groove 103, which greatly improves the installation efficiency, and by As for the limiting effect of the positioning tool 2 on the moving contact mechanism, the pressure head of the manual press 1 can accurately find the force application position without causing damage to the moving contact mechanism. A plurality of slots 8 are provided inside the positioning tool 2, and the slots 8 are used to avoid the moving contact 104, and a plurality of slots 8 are connected to the positioning slot 4. A limiting block 5 is fixedly connected to the top of the positioning tool 2, and the limiting block 5 is used to be inserted into the empty slot on the rear side of the moving bracket 101, thereby limiting the moving contact mechanism and preventing lateral displacement between the moving contact mechanism and the positioning tool 2.

[0019] Among them, a stopper 3 for blocking the positioning tooling 2 is fixedly installed on the manual press 1. The stopper 3 is used to block the positioning tooling 2, so as to position the moving contact mechanism placed on the positioning tooling 2, making it easier for the pressure head of the manual press 1 to align with the moving contact mechanism.

[0020] Among them, a protrusion 6 is provided on one side of the stop block 3, and a groove 7 matching with the protrusion 6 is provided on the side of the positioning tool 2 close to the stop block 3. When the moving contacts 104 at both ends are installed, after adjusting the position of the positioning tool 2, a small part of the positioning tool 2 will be in a suspended state, and then the set protrusion 6 cooperates with the groove 7 to avoid one end of the positioning tool 2 from tilting up during use, thereby ensuring its stability.

[0021] The stopper 3 is fixed to the manual press 1 by screws, and the stopper 3 is conveniently disassembled and assembled by screws.

[0022] Among them, the positioning fixture 2 and the stopper 3 are both made of steel. The steel is heavy, so it is not easy to shift during use. It is also strong and not easy to be damaged, and has a long service life.
