Description of drawings
Fig. 1 is the braking mechanism exploded view of the utility model one pin dual brake;
Fig. 2 is the interior cross-sectional view of braking mechanism ratchet sleeve of the utility model one pin dual brake;
Fig. 3 is the schematic perspective view after the braking mechanism of the utility model one pin dual brake is assembled;
The specific embodiment
As shown in the figure, the braking mechanism of one pin dual brake, comprise the ratchet sleeve 2 that contains pedal 1, ratchet sleeve 2 left and right sides have fastened braking top 6 respectively, can rotate relatively between ratchet sleeve 2 and the braking top 7, axletree 11 runs through ratchet sleeve 2 and braking top 6, ratchet sleeve 2 left and right sides inwalls are connected with retracing spring 7 respectively, retracing spring 7 other ends are connected braking top 6 inwalls, be provided with the ratchet 5 of band centre hole in the ratchet sleeve 2, axletree 11 passes the centre hole of ratchet 5, ratchet 5 both sides axial sections are provided with the bottom and are the brake groove on inclined-plane, several serration grooves of evenly arranging on ratchet 5 midcircumferential planes, the ratchet sleeve inwall is provided with the moving tooth axle, be with on the moving tooth axle with the moving tooth axle can counterrotating moving tooth 4, moving tooth 4 matches with the serration groove, be connected with retracing spring 3 between ratchet sleeve 2 inwalls and the moving tooth 4, ratchet 5 left and right sides are respectively equipped with brake pin 8, brake pin 8 passes braking top 6, be with retracing spring 9 on the brake pin 8, brake pin 8 two ends cooperate with brake groove and wheel upper locking groove on the ratchet 5 respectively, and brake is sold on 8 and is with axle sleeve 10.
This brake principle of work is as follows:
When pressing down pedal 1, ratchet sleeve 2 rotations, driving ratchet 5 by moving tooth 4 rotates, 7 elongations of extension spring 3 and retracing spring in ratchet 2 rotation processes, make brake pin 8 skid off the brake groove by the inclined-plane, retracing spring 9 shrinks, brake pin 8 one ends stretch out axle sleeve 10, and an end that stretches out axle sleeve 10 inserts the lock slots of wheel, realizes brake.
When pin left pedal 1, extension spring 3 and retracing spring 7 shrank, and pedal 1 is returned to the home position, and moving tooth 1 skids off the serration groove by the rotation of moving tooth axle, falls into next serration groove.
When pressing down pedal 1 once more, ratchet sleeve 2 rotations drive ratchet 5 by moving tooth 4 and rotate, extension spring 3 and retracing spring 7 elongations in ratchet 2 rotation processes, make brake pin 8 slip into next brake groove, retracing spring 9 elongations, brake pin 8 is removed brake near wheel one end separating wheel lock slots.
When pin left pedal 1, extension spring 3 and retracing spring 7 shrank, and pedal 1 is returned to the home position, and moving tooth 1 skids off the serration groove by the rotation of moving tooth axle, falls into next serration groove.
Repeat the above-mentioned action of trampling stretcher 1 that presses down, promptly repeated locking, this process of release the lock wheel.
