Embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment, belongs to the scope of protection of the invention.
As shown in Figs. 1-3, the embodiment of the present invention provides a kind of breaker easy to safeguard, including shell 1, shell 1 it is interior
Portion is installed with breaker body 2, and the side of shell 1 is provided with cover board 3, and shell 1 and cover board 3 are made of insulating materials, from
And make it that the insulation performance of breaker body 2 is guaranteed, and reduces the situation for occurring leaking electricity, the both sides of 1 outer surface of shell
Offer card slot 4.
Both sides inside cover board 3 offer straight slot 5, and the first spring 6, the first bullet are fixedly connected with the inner wall of straight slot 5
One end of spring 6 is fixedly connected with trapezoid block 7, and the side of trapezoid block 7 through straight slot 5 and extends to the inside of card slot 4, and trapezoid block
7 side inside card slot 4 opens up grooved hole 8, and the inside of slot 8 is connected with retaining mechanism 9, by setting the first spring 6
With trapezoid block 7 and slot 8, it is set to lock mechanism 9 consequently facilitating the dismounting of cover board 3 and shell 1 so that cover board 3 is dismantled
Get up more to simplify and include fixing pipe 901 with labor-saving use, retaining mechanism 9, by setting retaining mechanism 9 so that lid
Plate 3 is connected the more firm of fixation with shell 1, and then reduces the situation that cover board 3 is separated from shell 1 and occur, fixing pipe
The side of 901 inner cavities is installed with second spring 902, and one end of second spring 902 is fixedly connected with movable block 903, activity
The side of block 903 is welded with check lock lever 904, and one end of check lock lever 904 sequentially passes through fixing pipe 901 and shell 1 and extends to groove
The inner side in hole 8, and one end of check lock lever 904 is set for arcwall face, is set by setting one end of check lock lever 904 for arcwall face,
Consequently facilitating slip of the check lock lever 904 on 7 inclined-plane of trapezoid block, makes it slide more smooth, the opposite side weldering of trapezoid block 7
Pull rod 905 is connected to, one end of pull rod 905 through fixing pipe 901 and extends to the outer surface of fixing pipe 901 and is welded with fixed block
906, the opposite side of trapezoid block 7 is welded with connecting rod 10, and one end of connecting rod 10 through cover board 3 and extends to the appearance of cover board 3
Face, makes it drive movable block 903 to be moved so that mobile movable block 903 stretches the second bullet by pulling out pull rod 905
Spring 902, so that drive check lock lever 904 move and it is spun off from the inside of slot 8, and then in the bullet of the first spring 6
Property under make its drive trapezoid block 7 moved so that the inside of mobile trapezoid block 7 to straight slot 5 is moved, and then is made trapezoidal
Block 7 is collapsible into the inside of straight slot 5, then it is resetted under the elasticity of the first spring 6 in releasing lever 905, Ran Houzai
In a like fashion by other trapezoid blocks 7 shrink carry out straight slot 5 inside, and then can by pull cover board 3 by its
Disassembled from shell 1, having made it easy to the later stage disassembles cover board 3 breaker body 2 is safeguarded so that open circuit
Device body 2 can be operated normally, so as to be stopped for breaker body 2 or the work of distribution provides stable work
Environment, the both sides on 1 inner wall of shell are installed with heat sink 11, and the side of heat sink 11 is installed with heat absorbing sheet 12,
The another both sides of 1 outer surface of shell offer equally distributed heat emission hole 13, by heat absorbing sheet 12 so as to by 2 work of breaker body
Heat caused by work imports the inside of heat sink 11, and heat is distributed by heat sink 11 from heat emission hole 13, passes through setting
Heat sink 11 and heat absorbing sheet 12 are so that it can be when breaker body 2 works, and the heat that is produced is from 13 row of heat emission hole
Go out, and then good working environment is provided at work for breaker body 2, the side of 2 outer surface of breaker body is fixed
Disconnect switch 14 is installed, one end of disconnect switch 14 extends to the outer surface of cover board 3.
Operation principle：When in use, it is made to drive movable block 903 to be moved by pulling out pull rod 905 so as to move
Dynamic movable block 903 stretches second spring 902, so as to drive check lock lever 904 move and it is detached from the inside of slot 8
Come, and then make under the elasticity of the first spring 6 it drive trapezoid block 7 to be moved so that mobile trapezoid block 7 is to straight slot 5
Inside is moved, and then trapezoid block 7 is collapsible into the inside of straight slot 5, then makes it in the first spring 6 in releasing lever 905
Elasticity under resetted, then again in a like fashion by other trapezoid blocks 7 shrink carry out straight slot 5 inside, into
And it can be disassembled from shell 1 by pulling cover board 3；By heat absorbing sheet 12 so as to when breaker body 2 is worked
The heat of generation imports the inside of heat sink 11, and heat is distributed by heat sink 11 from heat emission hole 13.
In summary：This, by setting the first spring 6 and trapezoid block 7 and slot 8, matches somebody with somebody it easy to the breaker safeguarded
Retaining mechanism 9 is closed consequently facilitating the dismounting of cover board 3 and shell 1 so that cover board 3, which removes, more to be simplified and labor-saving
Use, and then be easy to the later stage to disassemble cover board 3 and breaker body 2 is safeguarded so that breaker body 2 can be normal
Carry out operate, so as to be stopped for breaker body 2 or the work of distribution provides stable working environment.
Also, should be easy to the breaker of maintenance, by setting retaining mechanism 9 so that cover board 3 is connected fixation with shell 1
It is more firm, and then reduce the situation that cover board 3 is separated from shell 1 and occur, while shell 1 and cover board 3 are by insulating materials
It is made, so that the insulation performance of breaker body 2 is guaranteed, reduces the situation for occurring leaking electricity, is dissipated by setting
So that it can be when breaker body 2 works, the heat produced is discharged from heat emission hole 13 for backing 11 and heat absorbing sheet 12,
And then good working environment is provided at work for breaker body 2.
