Abstract
The utility model discloses a universal wheel which comprises a middle plate, rolling wheels and a roller seat which is transversely penetrated on the bottom of the middle plate, wherein the middle plate and the roller seat are combined into integration, wheel shafts are arranged on the positions where the roller seat extends outside both sides of the middle plate and first buckling parts are respectively arranged on the outer walls of the two wheel shafts. A shaft hole is respectively and axially penetrated in the middle of each of the two rolling wheels, the inner walls of the shaft holes of the two rolling wheels are respectively provided with second buckling parts corresponding to the first buckling part and the two wheel shafts are respectively arranged in the shaft holes and are in slide fit with the two rolling wheels. The utility model has the advantages of large contact area of a rotary wheel and each wheel shaft, and simple manufacture technology; the stress area of each roller is enlarged, the utility model can bear large pressure and is not easy to damage and fall and the production cost is reduced.
Description
Technical field
The utility model belongs to a kind of cardan wheel that is applicable to tip-up seat.
Background technology
Be used for the cardan wheel on the moving articles such as tip-up seat, furniture at present, generally be by middle plate A, the axle sleeve B that establishes in the lower end of middle plate A, the metal wheel shaft C that on axle sleeve B, adorns, the runner D that installs respectively at two axle heads of metal wheel shaft B forms as shown in Figure 5, the runner of this cardan wheel and the area of contact of wheel shaft are little, the metal wheel shaft is yielding, middle plate and wheel shaft are the separation member package assembly, therefore make the area of thrust surface of runner little, it is little to bear pressure, fragile coming off, and the increase manufacture craft, increase productive costs.
Summary of the invention
It is big that the purpose of this utility model provides a kind of area of contact of roller and wheel shaft that can make, and bears big pressure, and roller is not allowed caducous cardan wheel.
The purpose of this utility model is to realize like this, it comprises middle plate, roller, also comprises the roller mount of plate bottom in laterally being placed through, and middle plate and roller mount are structure as a whole, it is wheel shaft that roller mount is stretched the position that places outside plate two sides, and the outer wall of great wheel arbor is respectively equipped with the first snapping portion; The centre of second wheel is axially run through an axis hole respectively, and the corresponding respectively first snapping portion of the shaft hole inner wall of second wheel is provided with the second snapping portion, and great wheel arbor places axis hole interior and the second wheel bearing fit respectively.
The utility model is because middle plate and roller mount are formed in one, and roller and roller mount upper whorl axial roll and cooperate that also area of contact is big, not only make runner can bear big pressure, be not easy damage and come off, and manufacture craft is simple, reduces production costs.
