The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Fig. 1～Fig. 6, a kind of universal rolling wheel body, the joint portion 2 of the first rotating shaft 11 pivotal joints that comprise supporter 1, extend by axial line along above-below direction on supporter 1, the roller 3 of the second rotating shaft 12 pivotal joints on joint portion 2 extending along horizontal direction by axial line, be provided with the stop mechanism with braking position and brake off position between joint portion 2 and roller 3.Stop mechanism comprises by extend the pedal 4 of the 3rd rotating shaft pivotal joint on joint portion 2 along horizontal direction, on supporter 1, have the first groove 6, on pedal 4, there is positioning unit 5, when stop mechanism is under braking position, positioning unit 5 is inserted in the first groove 6, when stop mechanism is under brake off position, positioning unit 5 and the first groove 6 are separated.
The second rotating shaft 12 departs from the axial line of the first rotating shaft 11.In the present embodiment, the first groove 6 is positioned at the rear side of the first rotating shaft 11, thereby makes the moulding of front side of supporter 1 more complete, attractive in appearance.Positioning unit 5 and the second rotating shaft 12 lay respectively at the both sides of the axial line of the first rotating shaft 11.Thereby when stop mechanism is under braking position, the second rotating shaft 12 is positioned at the front side of the axial line of the first rotating shaft 11.Universal rolling wheel body as a kind of in this is arranged at the front portion of shopping cart, conventionally on shopping cart, there is shopping bag, after shopping cart is folding, likely in shopping bag, there are article, now stop mechanism can be placed under braking position, the trailing wheel of i.e. the second rotating shaft 12 and shopping cart relative away from, thereby a kind of universal rolling wheel body can be preferably forms and supports the article in shopping cart and shopping cart with together with the trailing wheel of shopping cart.
Stop mechanism comprises the bearing pin 9 that is fixed on pedal 4 one ends, is opened in a plurality of the second grooves 10 on roller 3, a plurality of the second grooves 10 distribute and take on the circumferencial direction that the axial line of the second rotating shaft 12 is the center of circle, on pedal 4, there is pedal position 14, one side of bearing pin 9 line between the axle center of the 3rd rotating shaft 13 and the axle center of the second rotating shaft 12, the opposite side of pedal position 14 line between the axle center of the 3rd rotating shaft 13 and the axle center of the second rotating shaft 12.Positioning unit 5 is formed towards the direction of axis line extension of the first rotating shaft 11 by the part of pedal position 14.
Direction of axis line at bearing pin along the second rotating shaft 12 is slidably arranged on joint portion 2, pedal has the first inclined-plane on 4 one ends, on bearing pin, there is the second inclined-plane, when stop mechanism is under braking position, under the mating reaction on the first inclined-plane and the second inclined-plane, thereby bearing pin is ejected and inserted in the second groove 10.
Between pedal 4 and joint portion 2, be provided with spring 7, when stop mechanism is under braking position, the projection of spring 7 on pedal 4 is between the 3rd rotating shaft 13 and bearing pin 9, and when stop mechanism is under brake off position, the 3rd rotating shaft 13 is at spring 7 between the projection on pedal 4 and bearing pin 9.No matter stop mechanism is under braking position or under brake off position, and spring 7 can both play the effect of stabilized conditions.One end of spring 7 and the schematic diagram of pedal 4 in fitting process.
Pedal 4 with between joint portion 2, be provided with when stop mechanism by braking position to forbid in the process of brake off position conversion pedal 4 relative to joint portion 2 stop gears that rotate.As shown in Figure 3, stop gear comprises the engagement section being fixed on joint portion 2.The pedal position of pedal 4 14 is upwards lifted, and is that stop mechanism is placed in to braking position, and the pedal position of pedal 4 14 is stepped on downwards, is that stop mechanism is placed in to brake off position.
Those of ordinary skill in the art will be appreciated that, above embodiment is only for the present invention is described, and be not used as the restriction to a kind of universal rolling wheel body of the present invention, as long as within the scope of the connotation of a kind of universal rolling wheel body of the present invention, the variation of the above embodiment, modification all will be dropped within the scope of the claim of a kind of universal rolling wheel body of the present invention.
