Utility model content
For the deficiency that prior art exists, the purpose of this utility model is the residual current circuit breaker providing a kind of electricity theft prevention and screw to get rusty.
For achieving the above object, the utility model provides following technical scheme: a kind of residual current circuit breaker, comprise lower house and upper shell, described lower house is provided with binding post, described upper shell is provided with the through hole corresponding with binding post, corresponding installing hole is provided with between described upper shell and lower house, fixed screw is provided with in described installing hole, described upper shell is provided with the cover plate hinged with it, described cover plate covers through hole and installing hole, and described upper shell is provided with the fixed mechanism keeping cover plate for sealing through hole and installing hole.
Further, described fixed mechanism comprises the projection be arranged on upper shell, and described cover plate is provided with the groove passed for projection, and described projection top is provided with through hole.
Further, described upper shell is provided with the depressed part for placing cover plate, and described depressed part sidewall and cover plate exist gap near side, hinged place.
Further, described upper shell is provided with integrated convex axle with it, and described cover plate is provided with the axis hole coordinated with convex axle.
Further, described upper shell is provided with arc convex portion, described upper shell is hinged with the transparency cover coordinated with arc convex portion.
Further, described transparency cover is provided with shifting block away from hinged side, and described shifting block protrudes upper shell surface.
Further, described upper shell is provided with the LED light for showing keying.
Compared with prior art, the utility model has the advantage of: by the cover plate of covering through hole hinged on housing and installing hole, and cover plate realizes fixing by fixed mechanism, avoid dust impurity to drop and remain on installing hole and binding post, avoid on the one hand producing stealing electricity phenomenon and dangerous electrification, avoid screw to get rusty on the other hand and cause the situation being difficult to dismantle to occur.

Embodiment
Referring to figs. 1 through Fig. 2, the utility model residual current circuit breaker embodiment is described further.
A kind of residual current circuit breaker, comprise and upper shell 2, be provided with binding post 3, upper shell 2 is provided with the through hole 4 corresponding with binding post 3, upper shell 2 and between be provided with corresponding installing hole 5, fixed screw 6 is provided with in installing hole 5, upper shell 2 is provided with the cover plate 7 hinged with it, cover plate 7 covers through hole 4 and installing hole 5, upper shell 2 is provided with the fixed mechanism keeping cover plate 7 to seal through hole 4 and installing hole 5, fixed mechanism comprises the projection 8 be arranged on upper shell 2, and cover plate 7 is provided with the groove 9 passed for projection 8, and projection 8 top is provided with through hole 10.
Like this by the cover plate 7 of hinged covering through hole 4 and installing hole 5 on housing, time under cover plate 7 is covered, projection 8 passes from groove 9, there is certain friction with the conflict of groove 9 inwall in projection 8 on the one hand, play the effect of partial fixing cover plate 7, on the other hand by arranging through hole 10 at projection 8 top, at through hole 10 lead sealing bar can be set or lockset fixes cover plate 7, avoid dust impurity to drop and remain on installing hole 5 and binding post 3, avoid on the one hand producing stealing electricity phenomenon and dangerous electrification, avoid screw to get rusty on the other hand and cause the situation being difficult to dismantle to occur.
Wherein upper shell 2 is provided with the depressed part 11 for placing cover plate 7, depressed part 11 inwall is provided with the convex axle 12 be wholely set with it, cover plate 7 is provided with the axis hole coordinated with convex axle 12, gap is there is in depressed part 11 sidewall and cover plate 7 near side, hinged place, be convenient to the upset of cover plate 7, avoid cover plate 7 itself and depressed part 11 inwall when overturning to conflict and occur the phenomenon of clamping stagnation, and cover plate 7 realizes hinged by convex axle 12 integrated on upper shell 2, be convenient to processing, without the need to additionally arranging rotating shaft, save parts and cost.
Wherein upper shell 2 is provided with arc convex portion 13, upper shell 2 is hinged with the transparency cover 14 coordinated with arc convex portion 13, so in use may be used for mark, arc convex portion 13 places the note with mark, such as this circuit breaker is used for kitchen, again by covering transparency cover 14 and avoid the note of the inside to occur dropping or fuzzy by moisture or other dirty lanes, cause the situation being difficult to see clearly, well note is protected again when guaranteeing the content of inner note, be convenient to people to circuit breaker for where carrying out Fast Classification and identification, arc convex portion 13 and transparency cover 14 are close to the note inside avoiding and are occurred that mobile or fold causes situation about not seeing to occur simultaneously.
And transparency cover 14 is provided with shifting block 15 away from hinged side, shifting block 15 protrudes upper shell 2 surface, shifting block 15 better can be caught like this to be opened by transparency cover 14, operate more easily laborsaving when transparency cover 14 opened by needs.
Wherein upper shell 2 is provided with the LED light 16 for showing keying, arranges by LED light 16 keying showing circuit breaker, and then is convenient for people to learn what state circuit breaker is at present faster, simply bluntly to understand.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
