Including brake pedal 4 and the brake shoes to link therewith, the pedal 4 is hinged on rear side of installation portion and is upturned 20 °~30 °,
Angle can specifically be tilted and be set to 20 °, and it is connected to brake shoes by being arranged on the linkage in installation portion center, institute
State linkage to be hinged under pedal 4, including torsion spring is provided between pedal 4 and the linkage, the brake shoes is positioned at walking
Wheel rear side place on the upper side.By the linkage of pedal 4 and bar linkage structure, brake shoes easily can be pressed in walking wheel surface, by rubbing
Wiping power makes road wheel stop operating, and linkage is arranged on installation portion center, and Stability Analysis of Structures is durable in use；Can be by torsion spring
Linkage is set back rapidly after unclamping pedal 4, prevent it is stuck, it is convenient to brake next time；Meanwhile pedal 4 is hinged on peace
On rear side of dress portion and it is upturned 20 °~30 °, conveniently tramples and braked, found according to experiment, the tilting angle of pedal 4 is less than
20 ° of brakes are too laborious, and again bad more than 30 ° to trample, 20 °~30 ° of angle is the most convenient and strength-saving, and will not hinder on castor
The devices such as the dolly just installed, it is optimal angular range.
Preferably, the installation portion includes top plate 16, backing plate 17, intermediate plate 18 and the drain pan set gradually from top to bottom
19, top plate 16, backing plate 17, intermediate plate 18 and drain pan 19 are fixed as one by rivet, backing plate 17, intermediate plate 18 and the edge of drain pan 19
Center is provided with same central groove, and linkage is with regard in centrally disposed groove；Drain pan 19 is set to downwardly projecting cylindrical shell,
The rounded insertion in its bottom surface, the trundle bracket are arranged on drain pan 19.Trundle bracket is equipped with annular recessed including lower edges
The circular bearing plate in portion, the downside of intermediate plate 18 are provided with recess corresponding with recess, between the recess and recess on the upside of bearing plate, under
Some balls are equipped between the recess and drain pan 19 of side.A plectane is provided with the downside of bearing plate, trundle bracket is fixed by screw rod
Under plectane.By such structure, trundle bracket can is around longitudinally rotating, so as to be conveniently steered.
