Spring 73 and motor housing 2 are sequentially connected, and one end that pressing lever 72 extends to inside motor housing 2 is fixedly installed with lower platen 74,
Reset spring 73 is squeezed when pushing pressing lever 72, so that elastic deformation occurs for reset spring 73, unclamps pressing lever
Pressing lever 72 is resetted using reset spring 73 when 72, drives lower platen 74 to synchronize down when pressing lever 72 declines
Drop, to be pushed down on to arrestment mechanism 8, so that arrestment mechanism 8 is rotated around support shaft 9, convenient for arrestment mechanism 8 and system
Moving plate 6 contacts, to generate the function of braking；
Wherein, the quantity of support shaft 9 is two, and two support shafts 9 are symmetrically mounted on the inner wall of motor housing 2, and two
A support shaft 9 is symmetrically distributed in the two sides of brake disc 6；
Wherein the side of brake disc 6 is fixedly mounted there are six equally distributed screw rod, and the outside of six screw rods and braking
The side pivot bush unit of disk fixed plate 5, the threaded one end that six screw rods extend to 5 other side of brake disc fixed plate are connected with spiral shell
Mother enables fast when braking to brake disc 6 convenient for brake disc 6 to be fixedly connected with brake disc fixed plate 5
Speed brakes machine shaft 4, prevents from relatively rotating between brake disc 6 and machine shaft 4；
As shown in figure 4, arrestment mechanism 8 includes guide plate 81, the side of guide plate 81 offers installation through-hole 82, and installation is logical
The internal activity in hole 82 is socketed with support shaft 9, and the top of guide plate 81 offers rectangular channel, and the fixed peace in bottom of rectangular inner cavity
There are two symmetrical guide rod 83, the external activities of two guide rods 83 to be socketed with rotor plate 84 for dress, 84 outer surface of rotor plate
Bottom is actively socketed in the rectangular channel at 81 top of guide plate, and the top of guide rod 83 is fixedly connected with compressed spring 85, guide rod 83
It is sequentially connected by compressed spring 85 and rotor plate 84, the top of rotor plate 84 offers mounting groove, and the inner wall of mounting groove is solid
Dingan County is equipped with rotation axis 86, the outside of rotation axis 86 and the bottom pivot bush unit of lower platen 74, and lower platen 74 drives rotation axis 86
When rotation, the spacing between rotor plate 84 and guide plate 81 can be smaller and smaller, convenient for enabling lower platen 74 normal
It moves along the vertical direction, and the position of support shaft 9 will not change, so friction pad 87 can play the work of extruding to brake disc 6
With to brake to brake disc 6, the bottom of guide plate 81 is fixedly installed with friction pad 87；
Wherein, the center of rotation axis 86 and installation through-hole 82 is the center line of installation through-hole 82 to 87 bottom of friction pad away from value
Between four times of distance value one lesser power is applied to friction pad 87 using lever principle can play braking to brake disc 6
Effect, saved labour；
Wherein, 87 bottom of friction pad is shaped to arc surface, convenient for allowing friction pad when arrestment mechanism 8 rotates
87 slowly contact with the side of brake disc 6, and brake disc 6 is reduced speed now under the action of frictional force, plays buffering
Effect.
When braking, pressing lever 72 is pushed first, so that elastic deformation occurs for reset spring 73, it is right using lower platen 74
Rotor plate 84 is squeezed, so that rotor plate 84 is rotated around rotation axis 86, is moved straight down when due to lower platen 74, and
It needs to move in a circle when arrestment mechanism 8 rotates, can not move along vertical direction, in order to guarantee that arrestment mechanism 8 can
As lower platen 74 moves down, so by being sequentially connected between rotor plate 84 and guide plate 81 using compressed spring 85,
When lower platen 74 decline when rotor plate 84 and guide plate 81 also with rotation, and to compressed spring 85 carry out stretch or
Compression, so that the distance between rotor plate 84 and guide plate 81 are constantly changing, rotation when, drives the progress of friction pad 87
Rotation, and lever principle is utilized, brake disc 6 can be braked by applying a lesser power to rotation axis 86, be saved
Labor cost, since the bottom of friction pad 87 is set as arc surface, so with friction pad 87 around support shaft 9 rotates when
It waits, arc surface starts contacting with the side of brake disc 6 slowly, and brakes to brake disc 6, and braking is unclamped after completing
Pressing lever 72, reset spring 73 restore to reset pressing lever 72 when deformation.
