Abstract
The utility model provides a wheel for a roller. The wheel is simple in structure, impact resistant, and long in service life, and has an elastic buffering function, and comprises an outer wheel support, an inner wheel shaft and a supporting stand between the outer wheel support and the inner wheel shaft. The supporting stand supports the outer wheel support and the inner wheel shaft, the supporting stand is of an annular waved face structure, the waved face comprises wave crests and wave troughs, and the wave crests and the wave troughs are distributed in the radial direction of the wheel from the outer side of the inner wheel shaft to the inner side of the outer wheel support in a round spreading mode.
Description
Technical field
The utility model relates to the roller wheel, relates in particular to the wheel on roller for luggage.
Background technology
existing roller wheel, comprise outer wheel carrier, be provided with bracing frame between interior wheel shaft and outer wheel carrier and interior wheel shaft, bracing frame supports outer wheel carrier and interior wheel shaft, wherein bracing frame has the column reinforcing rib structure that plane ring plate structure is also arranged, but these two kinds all exist defective, the bracing frame of column reinforcing rib structure is when wheel is stressed, bracing frame is stressed or the most stressed near the column reinforcement of vertical direction by two of lower ends by the column reinforcement of the vertical direction in lower end, stressed comparatively concentrated, easily cause stressed that or two column reinforced ribs fractures, and the bracing frame of plane ring plate structure is when stressed, stress point also concentrates on a vertical curve, same stressed comparatively concentrating easily ruptured, and the bracing frame of these two kinds of structures can not produce deformation and come shock absorbing power when stressed, the function that does not possess elastic buffer.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of simple in structure, roller wheel with better elastic buffer function, shock-resistant, long service life is provided.
In order to solve the problems of the technologies described above, technical solution of the present utility model is such: a kind of roller wheel, comprise between outer wheel carrier, interior wheel shaft and outer wheel carrier and interior wheel shaft and be provided with bracing frame, bracing frame supports outer wheel carrier and interior wheel shaft, support frame as described above is the planar structure of annular wave, described wavy surface includes crest and trough, and distribution is dispersed to outer wheel carrier inboard rounded in described crest and the trough outside along the wheel radial direction from interior wheel shaft.
the beneficial effects of the utility model are: in above-mentioned technical solution, bracing frame is the planar structure of annular wave, described wavy surface includes crest and trough, distribution is dispersed to outer wheel carrier inboard rounded in described crest and the trough outside along the wheel radial direction from interior wheel shaft, this structure is when wheel is stressed, on the stress point of bracing frame may drop on that decline corrugated that crest to a trough is linked to be or trough to a crest be linked to be rising corrugated (being not in the vertical direction of the crest of bracing frame lower end or trough), and crest and the rounded structure of dispersing distribution of trough on bracing frame annular corrugated, make every section decline corrugated or rising corrugated all be the trapezoidal faces structure, and this trapezoidal faces structure is narrow near the interior shaft position of taking turns, put wide near the foreign steamer chord position, so just make the stressed comparatively even of bracing frame, stress point comparatively disperses, thereby easy fracture not, the stress point of bracing frame also may drop on a rising corrugated and decline corrugated (be bracing frame lower end have a crest or trough in the vertical direction) simultaneously, the stress point of bracing frame more disperses like this, more difficult fracture, and annular wavy bracing frame can be realized certain elastic deformation and not affect whole intensity when stressed, crest and the gradient between trough that its elastic deformation process is stressed corrugated flatten slow, extend to horizontal direction on rising corrugated or decline corrugated, so the roller that the utility model provides has simple in structure with wheel, has better elastic buffer function, shock-resistant, the characteristics of long service life.
Description of drawings
Fig. 1 is the roller that provides of the utility model with the integral structure schematic diagram of wheel.
Fig. 2 is the roller that provides of the utility model with the integral structure part sectional view of wheel.
The specific embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, the utility model provides a kind of roller wheel, comprise between outer wheel carrier 1, interior wheel shaft 2 and outer wheel carrier 1 and interior wheel shaft 2 and be provided with bracing frame 3, bracing frame 3 supports outer wheel carrier 1 and interior wheel shaft 2, support frame as described above 3 is the planar structure of annular wave, described wavy surface includes crest 4 and trough 5, distribution is dispersed to outer wheel carrier 1 inboard rounded in described crest 4 and trough 5 outside along the wheel radial direction from interior wheel shaft 2, and this roller has characteristics simple in structure, as to have better elastic buffer function, shock-resistant, long service life with wheel.
As shown in Figure 1 and Figure 2, crest 4 and trough 5 on the bracing frame 3 of the planar structure of described annular wave evenly distribute along the wheel circumference direction, the bracing frame 3 of this crest 4 and the trough 5 planar structures of well-distributed annular wave is stressed more even, and production and processing is more convenient.
Claims (2)
