The specific embodiment

Adjoint embodiment is described in detail as follows the utility model architectural feature and other effect, purpose:

Consult Figure 1 and Figure 2, the design of the utility model castor supporting structure, this castor mainly is made up of members such as wheel seat 1, brake gear 2 and rollers 3, wherein:

Wheel seat 1, as shown in Figures 1 and 2, it is the sheet pedestal of the approximate Jiong shape of a formation, it comprises a horizontal top board 11 and two side plates 12 that extended by these top board 11 both sides downwards, make two side plates 12 respectively offer a guide groove 121 in symmetric position place, the preceding bottom of pedestal, and two side plates 12 all on its plate body the select location place offer a plurality of knock holees 122 and a pivoted hole 123, and two side plates, 12 upper ends are each other apart from greater than distance between the bottom, make top board 11 be provided with a perforation 111 in centre, and one annular groove 112 is arranged in these 111 peripheral punching presses of boring a hole, get bearing in the annular groove 112 a plurality of steel balls 113 are arranged, perpendicularly in the upper end of this perforation 111 be provided with a rotating shaft 13, make the upper end shaft car of rotating shaft 13 that thread is arranged, thus must be affixed with the board screw lock, the hypomere shaft then is shaped to a corner post 131 (being illustrated as hexagon prism), make the back slotting wedging perforation 111 of corner post 131 in a nested last steel ball ring plate 14, make steel ball ring plate 14 can with steel ball 113 corrals in annular groove 112 to be built into a swivel bearing, the end of corner post 131 then extends perforation 111 bottoms for a fixed gear plate 15 riveted joint location, and between this fixed gear plate 15 and top board 11, be folded with a packing ring 151, making packing ring 151 inner rings be with a plurality of steel balls 152 to be built into another swivel bearing, so is that wheel seat 1 can be utilized on two swivel bearings, following clamping and depend on rotating shaft 13 rotation neatly;

Brake gear 2, as Fig. 1 and shown in Figure 3, it is one to be located in wheel seat 1 both sides side plate 12 in-to-in engine devices, formed by members such as two interlock plates 21, a brake catch 22 and two pedals 23, make two interlock plates 21 offer an axis hole 211 in the position of relative pivoted hole 123, offer the chute 212 of a curved arc shape in the position of relative guide groove 121, position with respect to each knock hole 122 convexes with positioning convex point 213 again, offers a caulking groove 214 in the top ends chosen place of two interlock plates 21; This brake catch 22 is the lamellar bodies with the moulding of metal sheet integrated punching, respectively dash in the front end both sides of lamellar body and to be provided with the lug 221 suitable with caulking groove 214, and the dual-side of lamellar body respectively protrudes out and forms a fin 222, make the end end face of lamellar body then arrange the retaining tooth 223 that is the curved arc shape again towards being provided with one, the flute profile of this retaining tooth 223, radian and fixed gear plate 15 are complementary, and for example shown in Figure 4, brake catch 22 each side revolves lock in the rear end plate body a brake shoes 224, and makes two pedals 23 be welded in the both side ends of two interlock plates 21 respectively;

Roller 3, as Fig. 1 and shown in Figure 3, it cooperates members such as an axle sleeve 31, a bolt 32 and a nut 33 and is located in the wheel seat 1, make roller 3 when assembling, this axle sleeve 31 placed the chute 212 of the core wheel of roller 3 and two interlock plates 21 in regular turn and stretched and placed guide groove 121, make roller 3 can be subjected to brake gear 2 the guiding of two interlock plates 21 and in guide groove 121 spacing moving (as shown in Figure 4), make bolt 32 insert from an end of axle sleeve 31, and stretch out with nut 33 sealedly from other end, roller 3 firmly is assembled in wheel seat 1.

By above-mentioned structure and the design of stack-mounted spatial relationship, the utility model do " castor supporting structure " design when practical operation, its pedal 23 by the device 2 that touches on the brake is down operated that reaching stops and is stopped action or discharge to stop and stops state (meaning promptly selected be positioned at a side pedal of eminence position and operate), be illustrated in figure 4 as castor and be in the state of not stopping and stopping, at this moment, the operator can step on the pedal 23 in left side down, make two interlock plates 21 utilize the pivoted hole 123 that is coupling mutually with wheel seat 1 to be the axle center with axis hole 211 places, to the anticlockwise direction turn, and when the 21 conter clockwise turns of two interlock plates, this chute 212 can follow guide groove 121 slippage to the right by pushing tow axle sleeve 31, force bolt 32 interlock rollers 3 to be passed in the lump thus to the right, make the axle center of the core wheel of roller 3 and rotating shaft 13 approaching, this core wheel shift motion can effectively reduce roller 3 and stop turn moment under the state in stopping.

And after the 21 conter clockwise turns of two interlock plates, this brake catch 22 that is positioned at two interlock plates, 21 upper ends also can interlock turn left, make the whole gear tooth 223 of brake catch 22 upper ends be advanced into mutual interlocking pattern (as shown in Figure 5) towards fixed gear plate 15, simultaneously, two brake shoes 224 of brake catch 22 rearward end also are resisted against the wheel face of roller 3 downwards because of angular relationship.So far, be to make roller 3 fully be subjected to the conflict of brake shoes 224 and reach to stop and stop state, and wheel seat 1 can not rotate also because of the mutual interlock of whole gear tooth 223 and fixed gear plate 15 obtains strong fix.

Otherwise, if being script to stop, desire stops state caster wheel when release, the operator can step on the pedal 23 on right side down, make brake gear 2 can comply with above-mentioned action reversed start, make brake catch 22 remove the state that touches with roller 3 and fixed gear plate 15, and make roller 3 follow guide groove 121 reduction of spondylolisthesis to the left, so, castor then must be replied original active state.

Moreover, the utility model is to make wheel seat 1 can guarantee that it is in the steady status in the stopping time of stopping, except the previous core wheel shift motion of addressing, (reduce turn moment), it has increased by catch 22 stop the stopping structure of position of can guaranteeing to brake again, the fin 222 that utilizes this brake catch 22 respectively to protrude out moulding in its both sides is exactly reached, it mainly is that the overall width of order brake catch 22 in two fins, 222 places is slightly larger than the internal face width of wheel seat 1 in two side plates, 12 upper ends, so, after 22 turns of two interlock plates, 21 primings brake catch, this two fin 222 promptly can form friction with two side plates, 12 internal faces and touch, the position of stopping of stopping of the catch 22 of can guaranteeing to brake.

Speech in addition, two interlock plates 21 of this brake gear 2 set positioning convex point 213 on its outer panel face, it can provide brake gear 2 to stop action or remove and stop when stopping state in reaching to stop, and forms corresponding chimeric and reach locating effect with the knock hole 122 of wheel seat 1.Only, the above only is preferred embodiment of the present utility model, when not limiting the scope that the utility model is implemented,, all should still belong to the scope that the utility model is contained so all simple and equivalences of doing according to the utility model claim scope and specification sheets change or modify with this.
