Abstract
The utility model discloses an automatic closing apparatus of a leakage protector. A unidirectional bearing is arranged on the eccentric output shaft of a motor; the unidirectional bearing is fixedly provided with a cantilever; for the arrangement of the unidirectional bearing, the eccentric output shaft is driven by the motor at only one direction without reverse rotation, and thereby the cantilever fixedly arranged on the eccentric shaft can only do unidirectional rotation movement; when the cantilever does unidirectional circumference rotation movement, a connecting rod is driven to do reciprocating motion, a handle is driven to do reciprocating motion back and forth, and thereby tripping and closing are achieved; and the connecting rod is connected with the handle through a high strength extension spring, repeat closing of a breaker is flexibly controlled by the extension spring to guarantee reliability, and faults such as closing failure and handle break for repeat closing not in place caused by assembling error and part processing error are prevented. According to the automatic closing apparatus of a leakage protector, the unidirectional bearing is employed to allow only unidirectional rotation of the cantilever without reverse rotation, maloperation is prevented, assembling of the unidirectional bearing is simpler and more convenient than a jump ring, and simultaneously, use of the unidirectional bearing is reliable without falling off.
Description
Technical field
The utility model relates to the closing device on a kind of earth leakage protective device, particularly 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
It is simple that the purpose of this utility model provides a kind of assembling, the automatic closing device of service-strong earth leakage protective device.
The utility model solves the problems of the technologies described above by following technical proposals:
A kind of automatic closing device of earth leakage protective device comprises motor, and the eccentric output shaft of motor connects unilateral bearing, and 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.
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.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, a kind of automatic closing device of earth leakage protective device comprises motor 2, and the eccentric output shaft 3 of motor 2 connects unilateral bearing 5, and unilateral bearing 5 is provided with cantilever 6, and cantilever 6 is hinged with an end of connecting rod 10, and the other end of connecting rod 10 connects handle 14.Axle sleeve 4 is installed earlier on the eccentric output shaft 3, unilateral bearing 5 is installed on axle sleeve 4 then again.Hinged by screw 7, back-up ring 8 and lock-screw 9 between cantilever 6 and the connecting rod 10.Extension spring 12 is fixedly arranged on the connecting rod 10, and extension spring 12 is fixing with the Handle axis 13 on the handle 14 by locking nut 11, thereby is connected with handle 14.
The automatic closing device is installed on the earth leakage protective device body 1; 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 3 rotates; eccentric output shaft 3 drives cantilever 6 and carries out unidirectional circumference rotation; cantilever 6 drivening rods 10 move forward or backward; thereby driving handle 14 moves forward or backward; as long as displacement is appropriate before and after designing circle diameter that cantilever turns over and handle; just can carry out automatic closing so that connecting rod 10 drives handle 14; connecting rod is connected by the high strength extension spring with handle, and 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 5 is installed on eccentric output shaft 3 and the cantilever 6, make cantilever 6 to rotate to a direction, avoided misoperation.
