Abstract
The utility model discloses an electric drive device for a residue leakage integrated protector, which comprises a motor and a one-way mechanism, wherein the motor comprises an output shaft; the one-way mechanism comprises a gear, a plug and a return spring, the gear is fixed on the output shaft of the motor, the plug is used for being inserted into the tooth space of the gear, and the reset spring is used for providing return elasticity for the plug. The electric drive device disclosed by the utility model effectively reduces the integral size and enhances the stability and the reliability of work by adopting the one-way mechanism with a more unique structure.
Description
Technical field
The utility model belongs to earth leakage protective device structure-design technique field, is specifically related to a kind of electric driver for the residue leakage comprehensive protector.
Background technology
Circuit breaker is widely used in the distribution system, traditional circuit breaker needs manually operation to remove to carry out closing operation when carrying out feed motion, if also there is electric arc in circuit breaker inside or when breaking down, operate manually dangerous property, so need electric operator to come driving handle, carry out breaking-closing operating.Electric driver in the conventional electric actuator, structure are comparatively complicated, and cost is higher, and easily breaks down, and still has the improvements of needing badly.
Summary of the invention
The purpose of this utility model provides comparatively compact and reasonable of a kind of structure, effectively reduces overall volume and improves the electric driver that is used for the residue leakage comprehensive protector of work stability and reliability.
The technical scheme that realizes the utility model purpose is: a kind of electric driver for the residue leakage comprehensive protector, comprise motor and one-way mechanism, and described motor comprises output shaft; Described one-way mechanism comprises the gear that is fixed on the motor output shaft, be used for inserting described gear teeth groove plug and be used to described plug that the back-moving spring of reseting elasticity is provided.
In the such scheme, described one-way mechanism also comprises the clutch seat and is used for the cover plate of gland on the clutch seat; Described clutch seat is provided with for the gear grooved of accommodating motor output shaft and gear and the clutch slot that is communicated with this gear grooved; Described plug and back-moving spring are arranged in this clutch slot.
In the such scheme, a side of described plug is connected on the gear teeth or teeth groove of gear, and another side is arranged in clutch slot.
In the such scheme, a side of each gear teeth is blocking surfaces on the described gear, and the another side is the arc shaped sliding surface.
The utility model is owing to adopting the comparatively unique one-way mechanism of structure, thereby effectively reduces overall volume and improve the reliability of work.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a kind of structural representation of one-way mechanism in the electric driver shown in Figure 1.
Be labeled as shown in the accompanying drawing: motor 1, output shaft 11, one-way mechanism 2, gear 21, the gear teeth 211, teeth groove 212, blocking surface 2111, arc shaped sliding surface 2112, plug 22, back-moving spring 23, clutch seat 3, gear grooved 31, clutch slot 32, cover plate 4.
Embodiment
(embodiment 1)
Fig. 1 and Fig. 2 have shown a kind of embodiment of the present utility model, and wherein Fig. 1 is a kind of structural representation of the present utility model; Fig. 2 is a kind of structural representation of one-way mechanism in the electric driver shown in Figure 1.
The present embodiment is a kind of electric driver for the residue leakage comprehensive protector, sees illustrated in figures 1 and 2ly, comprises motor 1 and one-way mechanism 2, and described motor 1 comprises output shaft 11.
Described one-way mechanism 2 comprises the gear 21 that is fixed on motor 1 output shaft 11, be used for inserting the teeth groove 212 of described gear 21 plug 22, be used to described plug 22 that back-moving spring 23, the clutch seat 3 of reseting elasticity is provided and be used for the cover plate 4 of gland on the clutch seat;
Described clutch seat is provided with for the gear grooved 31 of accommodating motor 1 output shaft 11 and gear 21 and the clutch slot 32 that is communicated with this gear grooved 31; Described plug 22 and back-moving spring 23 are arranged in this clutch slot 32.
One side of described plug 22 is connected on the gear teeth 211 or teeth groove 212 of gear 21, and another side is arranged in clutch slot 32.
For the ease of one-directional rotation, in the present embodiment, a side of each gear teeth 211 is blocking surfaces 2111 on the described gear 21, and the another side is arc shaped sliding surface 2112.
The present embodiment in use, if when motor output shaft 11 rotates along default one-directional rotation direction, plug 22 will slip over from arc shaped sliding surface 2112, until fall in the next teeth groove 212, each gear teeth 211 and plug 22 will can not hinder gear 21 to rotate; If during motor output shaft 11 default one-directional rotation direction backward rotation, plug 22 will be connected on the blocking surface 2111 of the gear teeth 211, stop gear 21 to rotate.
Obviously, above-described embodiment of the present utility model only is for the utility model example clearly is described, and is not to be restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all execution modes exhaustive.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection range of the present utility model.
