Technical field
The present invention relates to a kind of indicating mechanism, relate in particular to a kind of three station indicating mechanisms of withdrawable circuit breaker.
Background technology
Withdrawable circuit breaker can be divided into two relatively independent parts, promptly breaker body with take out frame.Breaker body has connection, test and separates three different positions in taking out frame.At present, there is complex structure in three station indicating mechanisms of withdrawable circuit breaker, the problem of assembling trouble, and its state indication accuracy that connects, tests and separate three positions is relatively poor.
Summary of the invention
The objective of the invention is to the problems referred to above; A kind of three station indicating mechanisms of withdrawable circuit breaker are provided; Solving three station indicating mechanism complex structures of existing withdrawable circuit breaker, the problem of assembling trouble, with and the relatively poor problem of three location statuss indication accuracy.
The objective of the invention is to realize through following technical scheme:
A kind of three station indicating mechanisms of withdrawable circuit breaker comprise and take out the frame base that the said frame base of taking out is provided with planker; Said planker is driven by power set, and it can being arranged at of front and back slip be taken out on the frame base, and an end of planker is connected with positioning groove plate; Have chute on the said positioning groove plate, said chute is provided with three grades of location notchs, and is provided with the reference column that can move forward and backward along this chute in the chute; Said reference column is fixedly installed on an end of connecting rod; The other end of said connecting rod is provided with indicating device, and the middle of connecting rod has axis hole, its be fixedly installed on the fixed axis of taking out on the frame base and be rotatably assorted.
Further, said power set are screw mandrel, and said screw mandrel comprises and be fixed on the nut of taking out the screw rod on the frame base and being mated that said nut is fixedly connected with planker.
Further, said indicating device comprises indication piece and Pointing sign board, and said indication piece links to each other with connecting rod, has been arranged side by side three indication windows on the said Pointing sign board.
Further, said connecting rod and reference column are structure as a whole.
Further, said connecting rod is the strip slab construction.
Beneficial effect of the present invention is that three station indicating mechanisms of said withdrawable circuit breaker are simple in structure, are easy to realize, and are easy to assembly, and its three location statuss indication accuracy is high, has satisfied the requirement that the withdrawable circuit breaker location status accurately shows.

Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through embodiment.
Please referring to figs. 1 through shown in Figure 3, in present embodiment, a kind of three station indicating mechanisms of withdrawable circuit breaker; Comprise and take out frame base 1, the said frame base 1 of taking out is provided with planker 3, and said planker 3 is driven by power set; Said power set are screw mandrel, and said screw mandrel comprises and be fixed on screw rod of taking out on the frame base 17 and the nut 2 that is mated that said nut 2 is fixedly connected with planker 3; Said planker 3 can before and after slide be arranged at and take out on the frame base 1, and an end of planker 3 is connected with positioning groove plate 4, has chute on the said positioning groove plate 4; Said chute is provided with three grades of location notchs, and is provided with the reference column 9 that can move forward and backward along this chute in the chute, and said reference column 9 is fixedly installed on an end of connecting rod 5; Itself and connecting rod 5 are structure as a whole, and said connecting rod 5 is the strip slab construction, and its other end is provided with indicating device; Said indicating device comprises indication piece 6 and Pointing sign board 8, and said indication piece 6 links to each other with connecting rod 5, has been arranged side by side three indication windows on the said Pointing sign board 8; The middle of connecting rod 5 has axis hole 10, its be fixedly installed on the fixed axis of taking out on the frame base 1 and be rotatably assorted.
Operation principle of the present invention is: with after an end of screw rod 7 is connected, rotating operating handle drives screw rod 7 rotations with operating grip; Thereby make the nut 2 that is mated on the screw rod 7 move forward and backward, nut 2 is fixedly connected with planker 3, drives planker 3 and moves forward and backward; Thereby driving positioning groove plate 4 moves forward and backward; Because the chute of positioning groove plate 4 is provided with three grades of location notchs, the reference column 9 in positioning groove plate 4 chutes slides in chute, makes connecting rod 5 rotate around fixed axis; Indication piece 6 move left and right of drivening rod 5 other ends, thus the state of accomplishing three stations is indicated.
Above embodiment has just set forth basic principle of the present invention and characteristic; The present invention is not limited by the foregoing description; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various variations and change, and these variations and change all fall in the scope of the invention that requires protection.The present invention requires protection range to be defined by appending claims and equivalent thereof.
