Abstract

The utility model relates to a double-power source changeover switch operating device with mechanical interlocking. The utility model is characterized in that a motor is installed between two plastic shell circuit breakers which are installed on a base board; a cam, a clamping plate, a cover plate and a twist grip which are fixedly provided with guide posts are respectively sheathed on a motor shaft; a swinging arm which is provided with a positioning hole and one end of which is fixed on the base board through a positioning pin is plugged in the side of the clamping plate through the cover plate; a convex plate is fixed on the twist grip; besides, a limit switch is fixed on the base board. The utility model not only has the advantages of simple structure, small size and low cost, but also has the characteristics that self mechanical interlocking structure can be flexibly operated, has an accurate action and can effectively avoid misoperation.

Description

The double power supply converting switch operator of band mechanical interlocking

The utility model belongs to H01H class technology, particularly relates to a kind of double power supply converting switch operator with mechanical interlocking.

At present, in the known duplicate supply switched system, generally all adopting two breaker of plastic casing to carry out power supply switches, and control adopts two electric operators breaker of plastic casing to be carried out the operation of division and combination too, in order to guarantee to have only a breaker of plastic casing to close, except electrical interlock, structure also to be arranged than the complicated mechanical interlock, complex structure so not only, but also have the big and high deficiency of cost of volume.Simultaneously, owing to adopt two electric operators that breaker of plastic casing is controlled,, promptly may cause the power failure phenomenon again so its mechanical interlocking is slipped up when moving sometimes easily.

The purpose of this utility model be to overcome the deficiency in the known technology and provide a kind of simple in structure, cost is low, only adopt an electric operator just can use double power supply converting switch operator with the band mechanical interlocking of standby conversion always to breaker of plastic casing.

The purpose of this utility model is achieved in that

Two breaker of plastic casing are installed on base plate of the present utility model, a motor is installed on the base plate between two breaker of plastic casing, be respectively installed with cam, clamping plate, cover plate and rotary handle by the motor shaft on the motor, on cam, be fixed with guide pillar, have the swing arm of location hole at clamping plate limit plug-in mounting by cover plate, the other end of swing arm is installed in base plate by alignment pin, is fixed with flange on rotary handle, also is fixed with limit switch on base plate.

The utility model has following accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the end view of Fig. 1;

Fig. 3 is the utility model work structuring schematic diagram under power supply commonly used;

Fig. 4 is the utility model work structuring schematic diagram under stand-by power supply.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

See figures.1.and.2, breaker of plastic casing 16 and breaker of plastic casing 17 are packed on the base plate 15, motor 14 is installed on the base plate between two breaker of plastic casing, on the motor shaft of this motor, be set with cam 2, clamping plate 9, cover plate 10 and rotary handle 20 successively, work as motor action, cam, clamping plate, cover plate rotate simultaneously with motor shaft is online.Be fixed with guide pillar 8 on above-mentioned cam, the clamping plate limit under cover plate respectively is fitted with swing arm 12, swing arm 6, and the other end of swing arm 12 is packed on the base plate by alignment pin 13; The other end of swing arm 6 also is packed on the base plate by alignment pin 5, between described swing arm and the alignment pin for movingly.In addition, be shaped on

location hole

19,18 respectively in swing arm 12 and swing arm 6, swing arm can accessiblely on alignment pin freely swing.Be fixed with

flange

7,11 respectively on the both sides of rotary handle, for making the motor location of stopping the rotation, also be fixed with limit switch 1, limit switch 3 and limit switch 4 on base plate, cam and flange are controlled limit switch in out of phase.

Operation principle of the present utility model is:

With reference to Fig. 3, it is that power supply breaker of plastic casing 16 commonly used is in the closing position state diagram.When two breaker of plastic casing all were in gate-dividing state, motor 14 was received the order that turns clockwise, and cam 2 turns clockwise simultaneously, turn round with cam, guide pillar 8 phase places change, and guide pillar progresses in the location hole 19 of swing arm 12, and guide pillar drive swing arm 12 is that rotate in the center of circle with alignment pin 13 like this.Breaker of plastic casing 16 operating grips are contained in the middle of the swing arm 12, so when swing arm 12 is center of circle rotation with alignment pin 13, drive breaker of plastic casing 16 operating grip translations, breaker of plastic casing 16 closes from assigning to gradually, at this moment flange 11 pushes up on the action bars of limit switch 1, limit switch 1 contact disjunction, motor 14 outages, motor stops operating.

With reference to Fig. 4, it is that power supply breaker of plastic casing 16 commonly used is in the sub-gate position configuration state, stand-by power supply breaker of plastic casing 17 is in the closing position state diagram.Motor 14 is received and is rotated counterclockwise order, and cam 2 is rotated counterclockwise simultaneously, and with the cam running, guide pillar 8 changes with cam phase, and it is that rotate in the center of circle with alignment pin 5 that guide pillar drives swing arm 6.Breaker of plastic casing 17 operating grips are contained in the middle of the swing arm 6, so when swing arm 6 is center of circle rotation with alignment pin 5, drive breaker of plastic casing 17 operating grip translations, breaker of plastic casing 17 closes from assigning to gradually, at this moment flange 7 pushes up on the action bars of limit switch 4, limit switch 4 contact disjunctions, motor 14 outages, motor stops operating.

Advantage and the good effect that the utlity model has are: because the utility model only adopts An electric operator just can be controlled moulding the shell breaker, so it has not only structure The advantage simple and volume is little and cost is low, but also have the mechanical interlocking structure that makes itself Not only simple but also use flexibly, characteristics that action has avoided fault phenomenon to take place accurately and effectively.

Claims

1. double power supply converting switch operator with mechanical interlocking, be by base plate, breaker of plastic casing, motor, limit switch, cam, alignment pin, swing arm, flange, guide pillar, clamping plate, cover plate is formed, it is characterized in that: two breaker of plastic casing are installed on base plate of the present utility model, a motor is installed on the base plate between two breaker of plastic casing, be respectively installed with cam by the motor shaft on the motor, clamping plate, cover plate and rotary handle, on cam, be fixed with guide pillar, have the swing arm of location hole at clamping plate limit plug-in mounting by cover plate, the other end of swing arm is installed in base plate by alignment pin, on rotary handle, be fixed with flange, on base plate, also be fixed with limit switch.
