Wherein, described fulcrum ball inhibiting device is provided in a side of the circular arc ring raceway or the flat ring raceway of fillet of described inner housing shoulder; Described fulcrum ball inhibiting device also can be provided in a side of a plurality of well-distributed ball recess that are spaced from each other of placing fulcrum ball that are respectively applied for of described inner housing shoulder.
Wherein, described sport ball restraint device is hollow reducing of well-distributed flange of inner housing cylinder lower port or flangeless hollow reducing.
Wherein, the connection mode of described stake body and described inner housing is that inner housing side or bottom are provided with the button pin, buckle into to be located at endoporus on the stake body, also can be, justify smooth surface in the described stake body and are connected with described inner housing cylindrical smooth surface flush fit; Also can be, described inner housing cylindrical be provided with annular or be interrupted annular boss, can buckle into the corresponding endoporus of stake body; Also can be, on described inner housing outside face, make boss or retaining pawl or reticulate pattern or straight burr, it is embedded stake body and integral molded plastic moulding, or the connection mode of described stake body and described inner housing be to fix with screw or rivet or cementation method.
Another object of the present invention is achieved in that a kind of method of making universal wheel unit of structure, it is characterized in that, may further comprise the steps: 1) make inner housing with the metallic material punching press; 2) make stake body with engineering plastics or plastic alloy injection moulding; 3) make the stop cover with engineering plastics or plastic alloy injection moulding; 4) with selected connection mode sectional shelf-unit body and inner housing; 5) in inner housing, pack into fulcrum ball and sport ball; 6) inner housing sport ball restraint device is worked; 7) the stop cover is installed.
Implement universal wheel unit provided by the invention and manufacture method, owing to simplified the structure of cardan wheel, part reduces, and cooperates and adopts injection molding, and cost reduces, and manufacturing equipment and operation reduce, and assembling is a kind of universal wheel unit that is worthy to be popularized easily.
Below in conjunction with accompanying drawing, further specify the present invention, in the accompanying drawing:
Fig. 1 is the structure cutaway view of an embodiment of universal wheel unit of the present invention.
Fig. 2 is an inner housing structural representation among Fig. 1 embodiment.
Fig. 3 is the structural representation of Fig. 1 embodiment medium-height trestle body.
Fig. 4 is the plan structure scheme drawing of Fig. 1 embodiment medium-height trestle body.
In the one embodiment of the present of invention shown in Fig. 1-Fig. 4, different with the prior art cardan wheel is that stake body of design 1 replaces connecting panel of the prior art, connect rivet and housing, and employing engineering plastics and plastic alloy injection mo(u)lding, less fulcrum ball 6 and a larger-diameter sport ball 5 of a plurality of identical sizes are housed in the cavity of stake body 1, for improving the wear resisting property of stake body, between stake body and fulcrum ball and sport ball, be embedded with one and can contain inner housing 2 fulcrum ball 6 and sport ball 5 and that adopt metal sheet stamping to become, be provided with reducing flanging 9 as sport ball restraint device (Fig. 2) at the edge of opening place of inner housing 2, be used for blocking sport ball 5, outside the cavity of stake body 1, place and be provided with continuously or intermittent screw thread 8, be used for stop cover 7, the following rotation, when sport ball lands, whole cardan wheel can be in ground surface, when rotation stop cover 7 covers sport ball, realize stop, rotate its turnover amount and realize adjustable height.Stop cover 7 also adopts engineering plastics or plastic alloy to make.From Fig. 1 as seen, universal wheel unit of the present invention only is made up of 5 parts, and than structure decrease 3-4 part of traditional cardan wheel, and to adopt plastics be raw material, makes the cost of this device reduce a lot.
As shown in Figure 3 and Figure 4, stake body 1 adopts engineering plastics or plastic alloy injection mo(u)lding, faces face mutually at itself and supported object and offers cavity, in other words is reinforced muscle and is divided into a plurality of cavitys, so that in proof strength simultaneously, reduces quantity of plastics.
As shown in Figure 2, be provided with a circular arc ring raceway of placing fulcrum ball, be used to fit in a plurality of fulcrum balls that annular places and roll betwixt, also can be arranged to the flat ring raceway of fillet at the shoulder of inner housing 2; Also can be made into ball recess spaced apart from each other and place fulcrum ball, can reduce the usage quantity of fulcrum ball.Be provided with the hollow reducing of flange of even branch at the mouth cylinder place of inner housing bottom, also can be designed to flangeless hollow reducing; The fixing means that is embedded in inner housing in the stake body chamber can adopt to make near the brace rod of stake body and be no less than 1 through hole, and correspondingly goes out lug button pin in the punching out of the bottom of inner housing, passes described through hole and curved being buckled on the dividing plate; Can also on the inner housing outside face, make boss, retaining pawl, reticulate pattern or straight burr profile, with the stake body integral molded plastic together; The bossy body that can also make annular or other than ring type boss or other shape on the inner housing periphery is stuck in the stake body chamber; Can also adopt the size of stake body chamber and the friction tight method that is dimensioned to of inner housing cylindrical are linked together; Can also adopt inner housing is connected with the method for stake body chamber with screw or rivet; Can also the method that inner housing sticks in the stake body chamber be connected with glue special, can also go out the riveted joint of flange hole and stake body flange in the bottom of inner housing.
Because the present invention optimizes the universal wheel unit structure, its Fabrication procedure can simplify, and as an embodiment of the inventive method, its manufacturing process can be realized like this: with the inner housing punch forming and carry out surface treatment; Stake body and the injection mo(u)lding of stop cover; Embed in the stake body inner housing also affixed; Pack in inner housing fulcrum ball and sport ball are with the edge flanging reducing constrained motion ball of inner housing bottom; Screw on the stop cover.Wherein, the moulding inner housing comprises following operation: cut material, blanking also stretches, cut flanged lip, stretching, dash button pin, electroplating surface.
