[specific embodiment]
Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail:
As shown in Figure 1 to Figure 3, a kind of brake castor, comprise runner 1, the rotating shaft of runner 1 is provided with braking erecting frame 2, above runner 1 cylindrical, be hinged with brake pedal 3 on the braking erecting frame 2, braking erecting frame 2 is provided with by brake pedal 3 drives and moves to and the brake assemblies 4 of runner 1 outer circumference surface contact friction braking and the elastic reset spare 5 that brake assemblies 4 can be resetted, and elastic reset spare 5 is spring.Braking erecting frame 2 two sides are provided with braking mounting hole 21, be provided with guide rod 22 in the braking mounting hole 21, brake assemblies 4 comprises that two ends stretch to the braking mounting blocks 41 in the braking mounting hole 21 respectively, be provided with slipper 42 on the braking mounting blocks 41 above runner 1 cylindrical, slipper 42 can be displaced downwardly on runner 1 outer circumference surface runner 1 friction braking.Elastic component 5 is sleeved on the guide rod 22 and an end leans on braking mounting blocks 41.Brake pedal 3 is provided with the flanging 31 that can all braking mounting blocks 41 be depressed when brake pedal 3 when hinge rotates.
It also comprises buffer beam 6, the middle part of buffer beam 6 is hinged with castor erecting frame 7, buffer beam 6 one ends are provided with shock absorption device 8, the other end is hinged in the rotating shaft of runner 1, shock absorption device 8 comprises and is located on the castor erecting frame 7 and is pressed against damping erecting frame 81 on buffer beam 6 one ends, damping erecting frame 81 is provided with mounting hole 82 and passes mounting hole 82 and guide pillar 83 that traversing through end can be left behind by buffer beam 6, and buffer beam 6 is by the pulling block 61 which is provided with guide pillar 83 to be left behind.Be set with elastic component 84 on the guide pillar 83, be with between elastic component 84 and damping erecting frame 81 on the guide pillar 83 and can be pushed by elastic component 84 and slide balance elastic component 84 acts on the control apparatus 9 of the elastic force on its end face, elastic component 84 is spring.Control apparatus 9 comprises the following regulating part 91 that is located on the damping erecting frame 81 and the adjusted part 92 that is located at down regulating part 91 upper support elastic components 84 1 ends, following regulating part 91 is provided with adjustment hole 92, the aperture of adjustment hole 92 is provided with arc surface 93, and adjusted part 92 is provided with and stretches into the cambered surface projection 94 that relative arc surface 93 rolls in the time of being pushed by elastic component 84 in the adjustment hole 92.
Course of action: during braking, brake pedal 3 is stepped on, brake pedal 3 will rotate around the hinged hinge of itself and braking erecting frame 2, the rotation of brake pedal 3 will make flanging 31 will brake mounting blocks 41 and depress, braking mounting blocks 41 moves down extrusion spring, after slipper on it 42 is braked with runner 1 cylindrical friction and with runner 1, and loosen the brake 3, braking mounting blocks 41 will reset under the restoring force of spring and move, and pushing tow flanging 31 simultaneously resets brake pedal 3; When runner 1 when running into thrust, runner 1 will produce shaking force, shaking force will make buffer beam 6 rotate around the hinge of itself and castor erecting frame 7, guide pillar 83 is left behind, because the pulling force of guide pillar 83 does not pass through the axis of guide pillar 83, will make elastic component 84 like this is that axial force suffered on every circle of spring is not of uniform size, to be subjected to elasticity squeese pressure not of uniform size on the end face that adjusted part 92 is pushed by elastic component 84 like this, sphere projection 94 on the adjusted part 92 will be rolled with respect to following regulating part 91, the elastic force of coming the balance end face to be subjected to, make larger axis to the orientation of power relatively to lower slider, thereby the suffered axial force of balance elastic component makes spring shaft to even compression, prevents spring failure.
