Description
Technical field
The utility model relates to a kind of earth leakage protective device.
Background technology
Notification number is the dual-purpose closing device of crank-type that the Chinese utility model of CN201522979 discloses a kind of residual current circuit breaker; this closing device utilizes the rotation of driven by motor crank; the reciprocating motion of crank drivening rod seesaws thereby drive handle, realizes tripping operation and the combined floodgate of earth leakage protective device.In this technical scheme, can only prevent its reversing to the rotation of direction in order to guarantee crank, adopt the eccentric shaft at motor to be with jump ring, block the connecting axle of crank and connecting rod by jump ring, crank can only rotate to a direction when rotating like this.But this mode at first is the assembling trouble of jump ring, and secondly in use, because crank rotates back and forth frequently, jump ring drops out easily, influences the use of closing device.
Summary of the invention
The purpose of this utility model provides a kind of earth leakage protective device with the automatic closing device, and its automatic closing device assembling is simple, uses reliably, in use can effectively avoid the generation of fault.
The utility model solves the problems of the technologies described above by following technical proposals:
A kind of earth leakage protective device with the automatic closing device; comprise the protector base; the protector base is provided with electronic circuit board; be provided with loam cake above the electronic circuit board, described protector base is provided with the automatic closing device, and the automatic closing device comprises motor; the eccentric output shaft of motor connects unilateral bearing; unilateral bearing is provided with cantilever, and an end of cantilever and connecting rod is hinged, and the other end of connecting rod connects handle.
On the described eccentric output shaft axle sleeve is installed, unilateral bearing is installed on the axle sleeve.
Described connecting rod is connected with handle by extension spring.
Described protector base is provided with the divide-shut brake indicating arm, is with spring on the divide-shut brake indicating arm, and loam cake is provided with the divide-shut brake indicator hole corresponding with the divide-shut brake indicating arm.
The utility model automatic closing device is installed unilateral bearing by the eccentric output shaft at motor, fixedly mount cantilever on the unilateral bearing, because the existence of unilateral bearing, can only and can't turn round to a direction rotation when the eccentric output shaft of driven by motor rotates like this, therefore the cantilever that is fixed on the eccentric shaft also can only unidirectionally rotate, in the unidirectional circumference rotation of cantilever, drivening rod moves back and forth, so just can drive the handle front-rear reciprocation movement, thereby realize tripping operation and combined floodgate, connecting rod is connected by the high strength extension spring with handle, extension spring soft readjustment circuit breaker is detained reliability again, avoids faults such as the button again that causes because of rigging error and part's machining errors close a floodgate failure or handle not in place fracture.The utility model adopts unilateral bearing to make that cantilever can only unidirectional rotation and can't turn round and prevent misoperation, and is more simple and convenient than jump ring in the time of the unilateral bearing assembling, simultaneously in use comparatively reliable, can not drop out.The protector base is provided with the divide-shut brake indicating arm simultaneously, divide-shut brake indicating arm lower end contacts with the rotating shaft of switch when the switch separating brake, the upper end is corresponding with the divide-shut brake indicator hole, when the earth leakage protective device separating brake disconnects, the switch rotating shaft ejects indicator hole with the divide-shut brake indicating arm, and at this moment protector is in the state that separating brake disconnects as can be seen; When earth leakage protective device closes a floodgate, the switch rotating shaft will no longer head on the divide-shut brake indicating arm, and the spring that is enclosed within like this on the indicating arm is withdrawn into indicating arm in the indicator hole, and at this moment protector is in the state of combined floodgate as can be seen; Adopt this mode to indicate the state of divide-shut brake, indicate relatively simple for structurely, move more stable.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, a kind of earth leakage protective device with the automatic closing device comprises protector base 1, and protector base 1 is provided with supply voltage device 5, electronic circuit board 11, be provided with loam cake 12 above the electronic circuit board 11, fixing by screw 13 between loam cake 12 and the protector base 1; Described protector base 1 is provided with the automatic closing device; the automatic closing device comprises motor 2, and the eccentric output shaft 21 of motor 2 connects unilateral bearing 4, and unilateral bearing 4 is provided with cantilever 6; cantilever 6 is hinged with an end of connecting rod 8, and the other end of connecting rod 8 connects handle 18.Axle sleeve 3 is installed earlier on the eccentric output shaft 21, on the axle sleeve 3 unilateral bearing 4 is installed then again.Hinged by back-up ring 9 and lock-screw 10 between cantilever 6 and the connecting rod 8; Be connected with extension spring 17 on the connecting rod 8, extension spring 17 is fixedlyed connected with handle 18 by locking nut 16.
When using earth leakage protective device; when owing to take place after trip phenomenon has taken place electric leakage or other fault; need carry out automatic closing; at this time motor 2 starts; driving eccentric output shaft 21 rotates; eccentric output shaft 21 drives cantilever 6 and carries out unidirectional circumference rotation; cantilever 6 drivening rods 8 move forward or backward; thereby driving handle 18 moves forward or backward; as long as it is appropriate to design the displacement that cantilever turns over before and after circle diameter and the handle; just can carry out automatic closing so that connecting rod 8 drives handle 18; connecting rod is connected by the high strength extension spring with handle; extension spring soft readjustment circuit breaker is detained reliability again, avoids faults such as the button again that causes because of rigging error and part's machining errors close a floodgate failure or handle not in place fracture.Close a floodgate into function signal when earth leakage protective device obtains, motor namely stops operating.Because unilateral bearing 4 is installed on eccentric output shaft 21 and the cantilever 6, make cantilever 6 to rotate to a direction, avoided misoperation.
In addition, protector base 1 is provided with divide-shut brake indicating arm 20, is with spring 19 on the divide-shut brake indicating arm 20, and loam cake 12 is provided with the divide-shut brake indicator hole corresponding with divide-shut brake indicating arm 20.Divide-shut brake indicating arm 20 lower ends contact with the rotating shaft of switch when the switch separating brake, the upper end is corresponding with the divide-shut brake indicator hole, when the earth leakage protective device separating brake disconnected, the switch rotating shaft ejected indicator hole with divide-shut brake indicating arm 20, and at this moment protector is in the state that separating brake disconnects as can be seen; When earth leakage protective device closes a floodgate, the switch rotating shaft will no longer head on divide-shut brake indicating arm 20, and the spring 19 that is enclosed within like this on the indicating arm 20 is withdrawn into indicating arm 20 in the indicator hole, and at this moment protector is in the state of combined floodgate as can be seen; Adopt this mode to indicate the state of divide-shut brake, indicate relatively simple for structurely, move more stable; And indicating arm directly do not contact with the divide-shut brake contact, and contact bounce shake and contact heating cause the indicating arm operation troubles when having avoided separating brake.
