Abstract
A labor-saving motor brake comprises a magnet yoke, a braking disc, a releasing plate, a sliding ball and a braking handle. An oblique channel and a straight channel are arranged on the back side of the magnet yoke. A solenoid coil and a spring are buried in the magnet yoke. One end of the spring is exposed on the front side of the magnet yoke. An armature is placed on the front side of the magnet yoke concentrically. The braking disc is arranged on the front side of the armature concentrically. The appearance of the releasing plate is defined by an arc side larger than a semicircle arc and a straight side. The top of the arc side corresponds to a straight channel. The releasing plate is connected with the braking disc through a screw which penetrates through the magnet yoke and the armature. An L-shaped releasing arm which extends outwards from the top of the arc side along the straight channel diameter and covers the upper portion of an oblique channel is arranged on the releasing plate. The releasing arm, the oblique channel and the straight channel define a sliding channel. A radial thread through hole formed above the oblique channel is formed in the releasing arm. The sliding ball is arranged in the sliding channel. The head portion of the braking handle is connected with the thread through hole in a thread mode. The head portion is provided with threads longer than the thread through hole. The labor-saving motor brake is simple in structure, labor is saved in operation, operation is convenient, and working efficiency is greatly improved.

Traditional electromotor brake is handle type or screw-type, when manual release, to draw three handles simultaneously or twist three screws, exert oneself greatlyr, debugging and maintenance and maintenance process are made troubles.
Summary of the invention
Based on this, for above-mentioned technical problem, provide a kind of laborsaving electromotor brake.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A laborsaving electromotor brake, comprising:
Yoke, the straight way that the rear side of described yoke has chute and the footpath that is connected with this chute extends internally, the external diameter of described chute reduces from front to back gradually, and is embedded with electromagnetic coil and spring in described yoke, and one end of described spring is exposed to the front side of described yoke;
Can be under the attraction of described electromagnetic coil backward lateral movement or under the elastic force of described spring the armature of lateral movement forward, described armature is positioned at the front side of described yoke with one heart;
Brake disc, described brake disc is positioned at the front side of described armature with one heart;
Be positioned at one heart the release board of the rear side of described yoke, the profile of described release board is greater than the arc-shaped edges of semi-circle and a straight flange by one and surrounds and form, the top of described arc-shaped edges is corresponding with described straight way, described release board is in transmission connection by screw and the described brake disc through described yoke and armature, on described release board, there is the L shaped release arm that stretches out from described arc-shaped edges top along described straight way footpath and be placed on described chute top, described release arm and described chute and straight way surround and form a slideway, and described release arm is provided with a radially tapped through hole that is positioned at described chute top,
Sliding pearl, described sliding pearl is located in described slideway;
Brake handle, the head of described brake handle is threaded with described tapped through hole, and this head has the screw thread of being longer than described tapped through hole length.
Described armature and brake disc are provided with a circle dirt-proof boot outward.
The utility model is simple in structure, easy to use, when maintenance has a power failure, the moving brake handle of layback drives release board to be subjected to displacement to rear side backward, and then can drive brake disc to leave motor end face, and braking is removed, simultaneously, brake handle is screwed in above-mentioned slideway from tapped through hole, the sliding pearl in slideway is moved in slideway, sliding pearl is snapped in straight way, make break maintain braking relieving state, without manpower, continue to force in brake handle, and the moment of brake handle is shorter, more laborsaving convenience.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments the utility model, be elaborated:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side-looking structural representation of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, a kind of laborsaving electromotor brake, comprises yoke 1100, armature 1200, brake disc 1300, release board 1400, sliding pearl 1500 and brake handle 1600.
The straight way 1120 that the rear side of yoke 1100 has chute 1110 and the footpath that is connected with this chute 1110 extends internally, the external diameter of chute 1110 reduces from front to back gradually, and in yoke 1100, be embedded with electromagnetic coil 1700 and spring 1800, one end of spring 1800 is exposed to the front side of yoke 1100.
Armature 1200 is positioned at the front side of yoke 1100 with one heart, and it can lateral movement or lateral movement forward under the elastic force of spring 1800 backward under the attraction of electromagnetic coil 1700.
Brake disc 1300 is positioned at the front side of armature 1200 with one heart, can by and motor end face between produce frictional force and pass to motor shaft and make motor braking.
Sliding pearl 1500 is located in above-mentioned slideway.
The head of brake handle 1600 is connected with tapped through hole screw thread 1411, and it has longer shank, and its head has the screw thread of being longer than tapped through hole 1411 length, and brake handle 1600 can be screwed in above-mentioned slideway from tapped through hole 1411.
When the electromagnetic coil 1700 in yoke 1100 is switched on, under the effect of electromagnetic force, armature 1200 is attracted to yoke 1100, and brake disc is released, and in releasing state, meanwhile, spring 1800 is pushed in compressive state by armature 1200.
When motor breaks down power-off, electromagnetic coil 1700 dead electricity, armature 1200, no longer by magnetic attraction, under the restoring force effect of spring 1800, makes armature 1200 tops to brake disc 1300, makes motor braking.
When maintenance has a power failure, can carry out manual release by brake handle 1600, braking is removed.
Particularly, the moving brake handle 1600 of layback drives release board 1400 to be subjected to displacement to rear side backward, and then can drive brake disc 1300 to leave motor end face, and braking is removed.
, brake handle 1600 is screwed in above-mentioned slideway from tapped through hole 1411 meanwhile, the sliding pearl 1500 in slideway is moved in slideway, sliding pearl 1500 is snapped in straight way 1120, make break maintain braking relieving state, without manpower, continue to force in brake handle 1600, laborsaving convenience.
Be understandable that, outside armature 1200 and brake disc 1300, be provided with a circle dirt-proof boot 1999, to prevent that dust from entering.
But, those of ordinary skill in the art will be appreciated that, above embodiment is only for the utility model is described, and be not used as restriction of the present utility model, as long as within the scope of connotation of the present utility model, to the above embodiment's variation, modification, all will drop within the scope of claims of the present utility model.
