Abstract
The utility model relates to a universal wheel means of a whole plastic support body, which comprises the support body. The support body is provided with an inner cavity filled with sport balls (and supporting balls). The periphery of the inner cavity is provided with the continuous or intermittent external thread used for being engaged with the stop sleeve of a helical sleeve. The approximal surface of the support body and the supported object is provided with a mounting hole. The universal wheel means of whole plastic support body has the advantages of simple structure, less parts, low cost and easy fabrication.
Description
The utility model relates to universal wheel unit, in particular, relates to a kind of universal wheel unit of overall plastic stake body.
Cardan wheel is a kind of mobile device that is widely used in utensil, article, and multiple structure is arranged.But the number of parts that generally all exists component devices is many, and most of part adopts that metallic material is manufactured, problem such as when cost height, set-up cost.
The purpose of this utility model provides a kind of universal wheel unit of overall plastic stake body; It is not only simple in structure, and cost is significantly less than existing product, and it is easier to make simultaneously, uses more conveniently, and the life-span is more permanent.
The utility model adopts following technical scheme to realize: three part designs such as the support in the former cardan wheel, housing, riveting pin axle are become a part stake body, and make with plastic injection-moulded, inner chamber at stake body is equipped with the inner housing that is used to install fulcrum ball and sport ball, is rotary with the stop cover on stake body.Specifically, the universal wheel unit of the overall plastic stake body that provides according to the utility model, comprise stake body, described stake body has inner chamber to lay sport ball, described stake body inner chamber periphery is provided with continuously or is interrupted outside thread and is used to mesh rotation set stop cover, and the adjacent surface of described stake body and institute's carrying object is provided with mounting hole.For improving the rolling alerting ability, the less fulcrum ball of a plurality of diameters also also is housed in described inner chamber body can be cooperated with the sport ball rolling.
In the universal wheel unit of the overall plastic stake body that provides according to the utility model, be provided with between described stake body inner chamber and described fulcrum ball, the sport ball and use the inner housing of making than high-abrasive material, one end of described inner housing is provided with attaching parts can captive joint with described stake body, and described inner housing another port is provided with the structure that prevents that described sport ball from coming off.Described inner housing is that sheet metal is stamped to form, and is provided with lug an end, and described lug bends and fixes being connected of inner housing and stake body by being located at through hole on the described stake body, is provided with the sport ball retaining means that bending forms in the other end.
In the universal wheel unit of the overall plastic stake body that provides according to the utility model, supported muscle is divided into two or more cavitys in the adjacent end face of described stake body and institute's carrying object.Described stake body adopts engineering plastics or plastic alloy injection molded, can be circle, rectangle, ellipse and other shape at the contact surface outer contour of stake body and institute's carrier.
Described stake body is provided with the spherical groove identical with the fulcrum ball number with described fulcrum ball adjacent surface, perhaps is provided with to be suitable for flat annular of fillet or the circular arc ring raceway that fulcrum ball rolls betwixt.
The universal wheel unit of the overall plastic stake body that enforcement the utility model provides, can simplified structure, reduce parts, thereby reduce manufacturing cost greatly, as can be seen, number of parts has reduced 1/3rd than traditional cardan wheel from embodiment, and vital parts adopts plastics to make, cost reduces, and is easy to manufacture, has wide market outlook.
Below in conjunction with drawings and Examples, further specify characteristics of the present utility model, in the accompanying drawing:
Fig. 1 is the structural representation of an embodiment of universal wheel unit of the present utility model.
Fig. 2 is the structural representation of inner housing among Fig. 1 embodiment;
Fig. 3 is the structural representation of Fig. 1 embodiment medium-height trestle body.
Fig. 4 is the plan structure figure of Fig. 1 embodiment medium-height trestle body.
An embodiment as the universal wheel unit of overall plastic stake body of the present utility model, as shown in Figure 1, comprise stake body 1, be contained in stake body 1 inner chamber fulcrum ball 2 and with fulcrum ball 2 sport ball 3 that cooperates etc. that rolls, between stake body 1 and a plurality of fulcrum ball 2 and sport ball 3, be provided with inner housing 4, place at stake body 1 outer and to be processed with continuously or the screw thread 5 that is interrupted, be used for stop cover 6 and screw on and screw off.On the adjacent surface of stake body 1 and institute's carrying object, be provided with mounting hole 7.
As shown in Figure 2, the inner housing 4 that metal between stake body 1 inner chamber and fulcrum ball 2, sport ball 3 or high-abrasive material are made is stamped to form for sheet metal, be provided with an end lug 10 as with the attaching parts of stake body 1, described lug 10 fixes being connected of inner housing and stake body by being located at 8 bendings of through hole on the described stake body, be provided with the sport ball barrier sheet 9 that bending forms in the other end, also can increase baffle ring, promptly go into the stake body periphery, block sport ball 3 and deviate from by the button climbers.
As shown in Figure 3 and Figure 4, stake body 1 is divided into two or more cavitys with the adjacent end face 11 interior supported muscle of institute's carrying object, with material saving on the proof strength basis.As other embodiment of the present utility model, stake body 1 can be provided with the spherical groove identical with the fulcrum ball number with the fulcrum ball adjacent surface, can save fulcrum ball, perhaps be provided with and be suitable for flat annular of fillet or the circular arc raceway that fulcrum ball rolls betwixt, to be applicable to the situation of filling fulcrum ball.
In other embodiment of the present utility model, can not have inner housing between stake body 1 and sport ball, the fulcrum ball, and adopt spheroid directly to contact with stake body.
In other embodiment of the present utility model, contact surface 11 outer contours of 1 carrier of stake body can be circle, rectangle, ellipse and other shape.
