Abstract
The utility model relates to a manual operation mechanism of a circuit breaker, comprising a bottom plate (7), a rotary shaft (6) which is arranged on the bottom plate and used for connecting with an operating handle and a crank arm (4) which is connected with the rotary shaft (6). The utility model is characterized in that the bottom plate (7) is rotatablely connected with a rotary plate through a rotary plate shaft (1). The crank arm (4) is provided with a bar-shaped long slot (5). The rotary plate (9) is inserted in the long slot (5). The utility model has the advantages of small manually operating friction, simple structure and lower production cost.
Description
The utility model relates to a kind of operating mechanism of circuit breaker.
In the prior art, the manual-operating mechanism of circuit breaker comprises base plate, be arranged at the rotating shaft that being used on the base plate be connected with operating grip, the connecting lever that is connected with described rotating shaft, described connecting lever is connected with bar-shaped trough on the slide plate, and slide plate can be slided up and down by the manipulation of connecting lever on base plate.The kind of drive of track slide plate is required great effort during manual operation because the friction of slide plate edge and guide rail makes operating physical force increase.
The purpose of this utility model is to provide the manual-operating mechanism of the little circuit breaker of a kind of frictional force.
The technical solution of the utility model is: the manual-operating mechanism of circuit breaker comprises base plate, be arranged at the rotating shaft that being used on the base plate be connected with operating grip, the connecting lever that is connected with described rotating shaft, be connected with finger plate rotationally by the finger plate axle on the described base plate, have the bar shaped elongated slot on the described connecting lever, described finger plate is inserted in this elongated slot.
The utility model compared with prior art has following advantage:
Because slide plate changes finger plate into, and be connected by rotating shaft between finger plate and the base plate, so its frictional force greatly reduces, its structure also becomes simply, can reduce production costs.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing 1 is a structural front view of the present utility model;
Accompanying drawing 2 is a left view of the present utility model; Wherein:
[1]. the finger plate axle; [2]. roller; [3]. roller; [4]. connecting lever; [5]. elongated slot; [6]. rotating shaft; [7] base plate; [8] breaker operator handle; [9]. finger plate;
Embodiment: referring to accompanying drawing 1 and accompanying drawing 2, the manual-operating mechanism of circuit breaker comprises base plate [7], be arranged at the rotating shaft [6] that being used on the base plate [7] be connected with operating grip, the connecting lever [4] that is connected with described rotating shaft [6], described base plate [7] is gone up and is connected with finger plate [9] rotationally by finger plate axle [1], have bar shaped elongated slot [5] on the described connecting lever [4], described finger plate [9] is inserted in this elongated slot [5].Also can be the another kind of structure that equivalence is replaced: have bar shaped elongated slot [5] on the described finger plate [9], described connecting lever [4] be inserted in this elongated slot [5].Described finger plate [9] is provided with roller [3], and this roller [3] is positioned at described elongated slot [5], and roller [3] and the cell wall of described elongated slot [5] be to roll and be connected, and can reduce the frictional force between connecting lever [4] and the elongated slot [5].Described finger plate [9] is provided with upper and lower two rollers [2], and breaker operator handle [8] is positioned between these two rollers [2].The end of described finger plate [9] is rotationally with base plate [7] and is connected.The manual operation handle drives connecting lever [4] rotation by rotating shaft [6], by the roller [3] on the drive finger plate of the elongated slot [5] on the connecting lever [4] [9], make finger plate [9] wraparound flap axle [1] rotation, drive the operating grip [8] of circuit breaker again by the pair roller [2] on the finger plate [9], circuit breaker is carried out actuating.
Claims (4)
1. the manual-operating mechanism of a circuit breaker, comprise base plate [7], be arranged at the rotating shaft [6] that being used on the base plate [7] be connected with operating grip, the connecting lever [4] that is connected with described rotating shaft [6], it is characterized in that: described base plate [7] is gone up and is connected with finger plate [9] rotationally by finger plate axle [1], have bar shaped elongated slot [5] on the described connecting lever [4], described finger plate [9] is inserted in this elongated slot [5].
The manual-operating mechanism of 2 circuit breakers according to claim 1 is characterized in that: described finger plate [9] is provided with roller [3], and this roller [3] is positioned at described elongated slot [5], and roller [3] and the cell wall of described elongated slot [5] are to roll and are connected.
