Abstract
The utility model provides a jump and detain indicating device for circuit breaker. Its characterized in that: press surface (211) one end be connected with that the slope sets up and with glide plane (22) that hasp (3) correspond. It is longer that the dropout stroke of indicating device's hasp is buckled in the jump of mainly having solved present circuit breaker, causes the problem of braking distance overlength. The utility model provides a jump and detain indicating device for circuit breaker, including the casing, swing joint has the button of instruction on the casing, is equipped with operating device and contact system in the casing, still including corresponding instruction button and the hasp that sets up, indicate be equipped with on the button be used for with the first boss of hasp lock complex, first boss top and hasp support the press surface of interference fit, press surface one end is connected with glide plane that the slope sets up and that correspond with the hasp. Be equipped with the glide plane on the press surface, reduced the length of press surface under the unchangeable condition of first boss maximum breadth to having reduced the dropout stroke, having reduced braking distance, it is more stable to make the circuit breaker use.
Description
Technical field
This utility model relates to field of circuit breakers, and a kind of tripping for chopper indicates device.
Background technology
Chopper has structure advanced person, dependable performance, the breaking capacity feature such as small and exquisite strong, aesthetic in appearance; overload and the short-circuit protection of making illumination, distribution line and the equipment of office building, house and similar building are used, and can act also as circuit infrequently make-break operation and are used with conversion.Existing chopper is provided with anticreep tripping instruction device mostly, and it includes snap close and the instruction button matched, but the dropout stroke of current snap close is longer, causes poor stop.
Utility model content
In order to overcome the deficiency of background technology, this utility model provides a kind of tripping for chopper to indicate device, and the dropout stroke of the snap close mainly solving the tripping instruction device of present chopper is longer, the problem causing poor stop.
This utility model be the technical scheme is that
A kind of tripping for chopper indicates device, including housing, it is connected with instruction button on described housing, the instruction button being correspondingly provided with in described housing and snap close, described instruction button is provided with for fastening, with described snap close, the first boss coordinated, described first boss top compresses the press surface coordinated with described snap close, and described press surface one end connects that be obliquely installed and corresponding with described snap close sliding surface.
Described sliding surface is arcwall face.
Described snap close upper end is provided with the pressure arm of inverted "L" shaped, is provided with and compresses face with described press surface by press-fit bottom described pressure arm.
Described housing bottom is provided with by the power transmission shaft of circuit breaker operation mechanism drive activity, is correspondingly provided with the second boss bottom described snap close with described power transmission shaft, and described power transmission shaft top is pressed in the bottom end face of described second boss.
Described first boss upper surface is additionally provided with the retaining wall corresponding with described pressure arm front end.
Described pressure arm is provided with the holding tank corresponding with described first boss.
The beneficial effects of the utility model are: this utility model provides a kind of tripping for chopper to indicate device, including housing, instruction button it is connected with on housing, operating mechanism and contact system it is provided with in housing, also include instruction button and the snap close being correspondingly arranged, instruction button is provided with for fastening, with snap close, the first boss coordinated, and the first boss top compresses the press surface coordinated with snap close, and press surface one end connects that be obliquely installed and corresponding with snap close sliding surface.Press surface is provided with sliding surface, decreases the length of press surface, thus decreases dropout stroke, decrease braking distance in the case of the first boss Breadth Maximum is constant, makes chopper use more stable.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings: as shown in the figure, a kind of tripping for chopper indicates device, including housing 1, it is connected with instruction button 2 on described housing 1, the instruction button 2 being correspondingly provided with in described housing 1 and snap close 3, described instruction button 2 is provided with for fastening, with described snap close 3, the first boss 21 coordinated, described first boss 21 top compresses the press surface 211 coordinated with described snap close 3, and described press surface 211 one end connects that be obliquely installed and corresponding with described snap close 3 sliding surface 22.Other structures of chopper, such as tripping mechanism, contact system etc. are prior art, repeat no more, this utility model provides a kind of tripping for chopper to indicate device, including housing, instruction button it is connected with on housing, operating mechanism and contact system it is provided with in housing, also include instruction button and the snap close being correspondingly arranged, instruction button is provided with for fastening, with snap close, the first boss coordinated, first boss top compresses the press surface coordinated with snap close, and press surface one end connects that be obliquely installed and corresponding with snap close sliding surface.Press surface is provided with sliding surface, decreases the length of press surface, thus decreases dropout stroke, decrease braking distance in the case of the first boss Breadth Maximum is constant, makes chopper use more stable.
In this utility model, as it can be seen, described sliding surface 22 is arcwall face.Snap close is slidably matched with sliding surface, withholds the process of the first boss or to leave the process operation of the first boss more steady at snap close, it is simple to use.
In this utility model, as it can be seen, described snap close 3 upper end is provided with the pressure arm 31 of inverted "L" shaped, it is provided with bottom described pressure arm 31 and compresses face with described press surface 211 by press-fit.Pressure arm is arranged to the shape of inverted L-shaped, it is simple to force, cut-offs rapidly, and using effect is good.
In this utility model, as shown in the figure, it is provided with by the power transmission shaft 43 of circuit breaker operation mechanism drive activity bottom described housing 1, pin of i.e. threading off with described power transmission shaft 43(bottom described snap close 3) it is correspondingly provided with the second boss 32, described power transmission shaft 43 top is pressed in the bottom end face of described second boss 32.
In this utility model, as it is shown in figure 5, described first boss 21 upper surface is additionally provided with the retaining wall 25 corresponding with described pressure arm 31 front end.After pressure arm is withheld and put in place, can be realized spacing by retaining wall, simple in construction, assembling is stable.
In this utility model, as it can be seen, described pressure arm 31 is provided with the holding tank 33 corresponding with described first boss 21.After pressure arm is withheld and put in place, the first projection section can fall in holding tank, and structure is compacter.
Embodiment is not construed as restriction of the present utility model, but any based on spirit improvements introduced of the present utility model, all should be within protection domain of the present utility model.
