The handle of the breaker is characterized in that the lever assembling groove (2) comprises a left limit side wall and a right limit side wall; a left clamping protruding block (4) is arranged on the left limit side wall; a right clamping protruding block (5) is arranged on the right limit side wall; when a lever (3) is arranged in the lever assembling groove (2) in a plug-in mounting mode, a left wall body split body and a right wall body split body of the lever are respectively connected with the left clamping protruding block (4) and the right clamping protruding block (5) in a clamping mode; and the handle body (1) is connected with the lever (3) in a clamping mode. The handle of the breaker is simple in structure and low in cost. Due to the fact that the handle body is tightly connected with the lever in a clamping mode, assembling is simple and quick, and the breaking speed of the breaker is improved.
Description
Technical field
The utility model relates to the especially functional unit of circuit breaker of circuit breaker, is a kind of handle of circuit breaker specifically.
Background technology
Existing circuit breaker, its functional unit is the handle that exposes, realize closing a floodgate and sub-switching operation by reciprocal driving handle, as shown in Figure 1, described handle comprises one handle main body 1, and its end face that is positioned at circuit breaker is provided with lever fitting recess 2, between handle main body 1 and the lever 3 is to live in joining connection, handle only is to rely on the loam cake of circuit breaker to realize spacing to it, and such connected mode has following defective:
1, circuit breaker is in assembling process, because that handle main body is connected with lever is not tight, comes off easily, influences assembling speed and production efficiency;
2, in debug process, because handle main body is connected not closely with lever, make the operator touch light current easily, make uncomfortable;
3, circuit breaker in use because handle main body is connected with lever and does not closely have looseningly, making in the on/off switch process easy and breaker upper cover friction influences service behaviour and breaking speed.
The utility model content
At the defective that exists in the prior art, the purpose of this utility model is to provide a kind of handle of circuit breaker, and is simple in structure, with low cost, and simple and fast is assembled in handle main body and lever compact engaging, has improved the breaking speed of circuit breaker.
For reaching above purpose, the technical scheme that the utility model is taked is:
A kind of handle of circuit breaker comprises handle main body 1, and its middle part, lower surface that is positioned at circuit breaker is provided with a lever fitting recess 2, it is characterized in that:
Described lever fitting recess 2 comprises left limit sidewall and right limit sidewall, is provided with left clamping projection 4 at the left limit sidewall, is provided with right clamping projection 5 at the right limit sidewall,
In the time of in lever 3 is inserted into this lever fitting recess 2, its left and right sides wall body split engages with left clamping projection 4, right clamping projection 5, makes clamping connection between handle main body 1 and the lever 3.
On the basis of technique scheme, in lever fitting recess 2, be provided with a location projection 6, the end face that lever 3 is positioned at lever fitting recess 2 is provided with the detent 7 adaptive with locating convex block 6.
On the basis of technique scheme, the width on the limit, left side 8 in detent 7 left sides is less than the width of the right edge 9 on detent 7 right sides,
Spacing between locating convex block 6 and the left limit sidewall and the width on limit, left side 8 are adaptive,
Spacing between locating convex block 6 and the right limit sidewall and the width of right edge 9 are adaptive.
On the basis of technique scheme, locating convex block 6 and handle main body 1 are for dividing body structure, and the two is plugged on together.
On the basis of technique scheme, locating convex block 6 and handle main body 1 structure that is formed in one.
The handle of circuit breaker described in the utility model, simple in structure, with low cost, simple and fast is assembled in handle main body and lever compact engaging, has improved the breaking speed of circuit breaker.
The handle of circuit breaker described in the utility model does not need breaker upper cover just can locate, and in debug process, because handle is connected closely with lever, has avoided the personnel in the experiment to touch the sense of discomfort that light current causes.
Description of drawings
The utility model has following accompanying drawing:
The structural representation of the handle of Fig. 1 existing circuit breaker,
The structural representation of the handle of Fig. 2 circuit breaker of the present utility model,
The structural representation of handle main body among Fig. 3 Fig. 2,
The structure vertical view of lever among Fig. 4 Fig. 2.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Shown in Fig. 2,3,4, the handle of circuit breaker described in the utility model comprises:
Handle main body 1, its middle part, lower surface that is positioned at circuit breaker is provided with a lever fitting recess 2,
Described lever fitting recess 2 comprises left limit sidewall and right limit sidewall, is provided with left clamping projection 4 at the left limit sidewall, is provided with right clamping projection 5 at the right limit sidewall,
In the time of in lever 3 is inserted into this lever fitting recess 2, its left and right sides wall body split engages with left clamping projection 4, right clamping projection 5, makes clamping connection between handle main body 1 and the lever 3.
On the basis of technique scheme, in lever fitting recess 2, be provided with a location projection 6, the end face that lever 3 is positioned at lever fitting recess 2 is provided with the detent 7 adaptive with locating convex block 6.
In the time of in lever 3 is inserted into this lever fitting recess 2, locating convex block 6 inserts detent 7, and lever 3 can be accurately positioned in the lever fitting recess 2.
On the basis of technique scheme, the width on the limit, left side 8 in detent 7 left sides is less than the width of the right edge 9 on detent 7 right sides, spacing between locating convex block 6 and the left limit sidewall and the width on limit, left side 8 are adaptive, and the spacing between locating convex block 6 and the right limit sidewall and the width of right edge 9 are adaptive.Width difference by both sides has realized the fool proof design, and the assembly crewman can't oppositely insert lever 3 in the lever fitting recess 2, has improved fail safe, and has made that assembling process is simpler, accurate, high efficiency.
On the basis of technique scheme, locating convex block 6 and handle main body 1 are for dividing body structure, and the two is plugged on together.
