Aforesaid a kind of damping castor, it is characterized in that: described control apparatus comprises the following regulating part that is located on the described damping erecting frame and is located at the described adjusted part of regulating part upper support elastic component one end down, described regulating part down is provided with adjustment hole, the aperture of described adjustment hole is provided with arc surface, and described adjusted part is provided with and stretches in the adjustment hole cambered surface projection of rolling with respect to described arc surface can be by described elastic member presses the time.
Aforesaid a kind of damping castor, it is characterized in that: described buffer beam is provided with the pulling block that blocks described guide pillar lower end.
Aforesaid a kind of damping castor is characterized in that: described elastic component is spring.
Aforesaid a kind of damping castor, it is characterized in that: the rotating shaft of described runner is provided with the braking erecting frame, be hinged with brake pedal on the described braking erecting frame above described runner cylindrical, described braking erecting frame is provided with by described brake pedal drive and moves to and the brake assemblies of runner outer circumference surface contact friction braking and the elastic reset spare that described brake assemblies can be resetted.
Aforesaid a kind of damping castor, it is characterized in that: described braking erecting frame two side is provided with the braking mounting hole, be provided with guide rod in the described braking mounting hole, described brake assemblies comprises that two ends stretch to the braking mounting blocks in the braking mounting hole respectively, be provided with slipper on the described braking mounting blocks above described runner cylindrical, described elastic reset spare is sleeved on the described guide rod and an end is shored the braking mounting blocks.
Aforesaid a kind of damping castor is characterized in that: described brake pedal is provided with the flanging that can all described braking mounting blocks be depressed when brake pedal when hinge rotates.
Aforesaid a kind of damping castor, it is characterized in that: described elastic reset spare is spring.
The beneficial effects of the utility model have: be provided with shock absorption device at runner, can make when rolling on the uneven road of runner, can the absorption portion shaking force, thereby reduce the application force to trundle bracket, reduce the shaking force of transportation goods, shock absorption device is provided with control apparatus, when castor is subjected to greater impact power, the drop-down guide pillar of buffer beam, elastic component is extruded, because buffer beam can rotate around the hinge with the castor erecting frame, therefore the pulling force that produces of buffer beam will be not can be by leading the axle center, the big side of squeese pressure one side that is subjected to of elastic component is little like this, the elastic force that causes acting on the control apparatus end face is inhomogeneous, the end that the adjusted part is subjected to big elastic force will descend regulating part to roll relatively, make the stressed bigger end of adjusted part relatively to lower slider, thereby one side dynamics that makes elastic component be subjected to big squeese pressure reduce, and spring is evenly shunk, can prevent that spring from owing to shrinking uneven the inefficacy, improving the service life of shock absorption device; Brake pedal and brake assemblies all are located at runner cylindrical top, drive brake assemblies when stepping on brake pedal like this and move on the runner cylindrical, with the runner braking, can not produce eccentric force, the safety performance height.

[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 damping castor, comprise buffer beam 6, the middle part handing-over of buffer beam 6 has 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, buffer beam 6 is provided with the pulling block 61 that blocks guide pillar 83 lower ends, and pulling block 61 blocks pulling block 61 lower ends, thereby buffer beam 6 is left behind guide pillar 83 by pulling block 61, be set with elastic component 84 on the guide pillar 83, elastic component 84 is spring.Between elastic component 84 and damping erecting frame 81, be with 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 of its end face.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 of rolling with respect to arc surface 93 in the time of being pushed by elastic component 84 in the adjustment hole 92.Because the suffered squeese pressures of elastic component 84 are by axis, thus elastic component 84 to act on the squeese pressure that adjusted part 92 end faces distribute inhomogeneous, adjusted part 92 is rolled relative arc surface 93, a stressed bigger end is tilted to down.
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, elastic reset spare 5 is sleeved on the guide rod 22 and an end is shored 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, when brake pedal 3 flanging 31 when hinge rotates will be depressed braking mounting blocks 41, drive slipper 42 and move on runner 1 outer circumference surface, make runner 1 friction braking.
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 the axial force received 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 balance elastic component 84 suffered axial forces make spring shaft to even compression, prevent spring failure.
