Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, new to this practicality below in conjunction with accompanying drawing
Type is described in further detail.
As shown in Figure 1-2, the embodiment that this utility model provides, a kind of brake device for electrical machinery with hand switch, its
Including coil holder 10, connect the collar 20, disc brake assembly 30 and motor top cover 40, described coil holder 10 and motor top cover 40 respectively
Be connected to the described connection collar 20 top and bottom, and form the inner chamber of a closing, described disc brake assembly 30 be arranged at described in
Intracavity, described motor top cover 40 is provided centrally with shaft hole.
Being provided with magnet exciting coil 11 in described coil holder 10, described coil holder 10 is provided centrally with through hole, in described through hole
The activity of being provided with is interspersed in the movable compression leg 13 of described through hole, and described movable compression leg 13 upper end is stretched out described through hole and passes through pin
It is hinged with toggle switch 16.Described movable compression leg 13 lower end is provided with outwardly round platform 14, and described through-hole wall is provided with
Inwardly projecting annular chuck 12, described movable compression leg 13 periphery is arranged with back-moving spring 15, described back-moving spring 15 lower end with
Described round platform 14 upper surface abuts, and described back-moving spring 15 upper end abuts with described annular chuck 12 lower surface.
Described annular chuck 12 upper surface is provided with elastic washer 17.Wherein, elastic washer 17 can be to toggle switch 16
Play the effect of buffer protection.
Described disc brake assembly 30 includes upper brake block 31, brake disc 32 and the lower brake block 33 arranged from top to bottom, institute
State brake disc 32 and be provided centrally with transmission articulation 34.Wherein, the rotating shaft of motor is connected through shaft hole with transmission articulation 34.
Described coil holder 10 is provided with O-ring seal 21 with described connection between the collar 20；Described motor top cover 40 is with described
Connect and be provided with O-ring seal 21 between the collar 20.Wherein, O-ring seal 21 can improve the seal of inner chamber, prevents in inner chamber
Brake fluid spill.
Described coil holder 10 is provided with screwed hole, and described motor top cover 40 upper surface is provided with corresponding with described screwed hole
Threaded post, bolt coordinates through described screwed hole with described threaded post makes described coil holder 10 be fixed on described motor top cover 40.
Described upper brake block 31 and lower brake block 33 are provided with and the escape groove of described threaded post corresponding matching.Wherein, keep away
Allow groove can not only avoid threaded post, also can prevent brake block 31 and lower brake block 33 from rotating.
As it is shown on figure 3, due to pin to toggle switch 16 bottom surface distance Q more than pin to toggle switch 16 side away from
From P, so: when described toggle switch 16 is horizontally disposed with, described toggle switch 16 drives described round platform 14 to stretch in described through hole
And it is movable to limit described movable compression leg 13, brake gear is closed；When described toggle switch 16 is vertically arranged, stir out
Closing 16 and be not intended to described movable compression leg 13 activity, brake gear is in opening.
When brake gear is closed, owing to the round platform 14 of movable compression leg 13 stretches in through hole, and movable compression leg
13 can not be up and down, so upper brake block can not be pressed for 31 times by movable compression leg 13, thus with transmission articulation 34 transmission
The machine shaft connected will not be by restriction campaign.When brake rotating shaft is in opening, owing to movable compression leg 13 will not be fixed,
Movable compression leg 13 can move up and down, and brake gear is by circuit control.
This utility model, by arranging movable compression leg 13 and toggle switch 16, enables installation motor of the present utility model to exist
Normal operation is continued after the malfunctioning power-off of brake gear；Meanwhile, user can also the most actively close brake gear, makes
With flexibly.
Above disclosed only this utility model preferred embodiment, can not limit this utility model with this certainly
Interest field, the equivalent variations therefore made according to this utility model claim, still belong to the scope that this utility model is contained.
