Abstract

The utility model relates to a special wrench for a circuit breaker operating mechanism, which belongs to the technical field of hand tools and can effectively solve the problem that the circuit breaker operating mechanism is not easy to operate in a place with a narrow inner space. It includes a handle, an extension arm and a fixed platform, the handle, the extended arm and the fixed platform are located on the same plane and the handle and the fixed platform are parallel, and the two ends of the extended arm are respectively connected to one end of the handle and one end of the fixed platform, The angle between the extension arm and the handle and the angle between the extension arm and the fixed table range from 10° to 150°; A detachable sleeve head is sheathed on the post. The utility model has a simple structure, and the maintenance work inside the operating mechanism of the circuit breaker can be transferred to the outside operation, which reduces the danger points on the maintenance site and greatly improves the work efficiency.

Description

The circuit breaker operation mechanism special spanner

Technical field

The utility model relates to a kind of special spanner, especially a kind of circuit breaker operation mechanism special spanner.

Background technology

At present, circuit breaker operation mechanism internal overhaul work, as change minute, the task such as closing coil, common spanner is difficult to insert into the inner section, the operating personnel does not have suitable instrument, brings inconvenience for the service work of operating mechanism.On the one hand, increase the operation dangerous spot, easily squeezed wound, the service work personnel's that damage hand; On the other hand, expend a large amount of manpowers and valuable time, reduced service work efficient.

The utility model content

The purpose of this utility model is to provide a kind of circuit breaker operation mechanism special spanner, and this spanner can effectively solve in narrow and small place, circuit breaker operation mechanism inner space does not allow easy-operating problem.

In order to address the above problem, the utility model is by the following technical solutions: the circuit breaker operation mechanism special spanner, comprise handle, extension arm and fixed station, it is characterized in that, described handle, extension arm and fixed station are positioned at same plane and handle is parallel with fixed station, be connected an end with an end of handle respectively and be connected in the two ends of described extension arm with fixed station, the angle that described extension arm becomes with handle is 10 ° to 150 ° with the angular range that extension arm becomes with fixed station; Described fixed station bottom surface is provided with a collet head shank, is equipped with dismountable collet head on the described shank.

Further, described collet head can be yi word pattern.

Further, described collet head can also be cross.

Further, described collet head also can be interior hexagon.

The beneficial effects of the utility model are: this specific purpose tool is simple in structure, on the one hand owing to having increased by two turnings, when having satisfied the spanner lever principle, service work with circuit breaker operation mechanism inside changes peripheral operation over to again, thereby make the operating personnel can avoid mechanism and squeeze the threat of hindering, damaging, reduced the dangerous spot of Overhaul site; On the other hand, this spanner also has been equipped with multiple sleeve, applicable to the various bolts in circuit breaker operation mechanism inside, nut, provides convenience to service work and greatly to have improved operating efficiency.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the collet head of the first embodiment of the present utility model;

Fig. 3 is the collet head of the second embodiment of the present utility model;

Fig. 4 is the collet head of the 3rd embodiment of the present utility model.

Among the figure: 1 handle, 2 extension arms, 3 fixed stations, 4 collet head shanks, 5 collet heads.

The specific embodiment

As shown in Figure 1.The spanner of this utility model comprises handle 1, extension arm 2 and fixed station 3, described handle 1, extension arm 2 and fixed station 3 are positioned at same plane and handle 1 is parallel with fixed station 3, the two ends of described extension arm 2 are connected with the end that an end of handle 1 is connected with fixed station respectively, and described extension arm 2 is 10 ° to 150 ° with the angle of 1 one-tenth on handle with extension arm 2 and the angular range of 3 one-tenth of fixed stations; Described fixed station 3 bottom surfaces are provided with a collet head shank 4, are equipped with dismountable collet head 5 on the described shank.

Such as Fig. 2, Fig. 3 and shown in Figure 4, described collet head 5 forms a cover by yi word pattern, each one of cross and interior hexagon.

A kind of implementation size of spanner is provided here, and collet head shank 4 length are 50mm, and the length of collet head 5 is 100mm, and fixed station 3 is the square of 50mm for the length of side, and the vertical range between fixed station 3 and the handle 1 is 70mm.

When using this special spanner to carry out the circuit breaker operation mechanism maintenance, specifically use step as follows:

1, opens the circuit breaker operation mechanism shell;

2, according to screw (mother) type that will rotate, select and the assembly wrench collet head;

3, hold the special spanner handle, collet head is firmly beaten on the screw that will rotate (mother).Alternatively up and down firmly uses this spanner that screw (mother) is unloaded in mechanism;

4, overhaul or changed the circuit breaker operation mechanism inner part;

5, the screw (mother) that unloads is screwed install and install the circuit breaker operation mechanism shell;

6, site clearing, service work finishes.

The above is preferred embodiment of the present utility model; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also are regarded as protection domain of the present utility model.
