Abstract

A universal wheel comprises a wheel seat and a wheel foot, and a wheel is arranged on the lower shaft of the wheel foot. The universal wheel is characterized in that a longitudinally rotating bearing is fixed on the wheel seat; more than one fixing hole for fixing the wheel seat on a case is formed on the back of the wheel seat; and a rivet fixed in the center of the upper part of the wheel foot is inserted into the bearing to fix the wheel seat and the wheel foot together. The structure of the universal wheel is simple because parts used in the structure are reduced, so that the disassembly and the assembly of the universal wheel are simple and the cost is saved.

Description

Cardan wheel

Technical field

The utility model relates to a kind of cardan wheel, and this cardan wheel is mainly used in case and bag.

Background technology

Therefore trolley luggage can make the luggage rolling move ahead because the bottom has roller, thereby has saved people's muscle power.Cardan wheel is because can rotate to either direction, and is easy to use, so also be widely used in case and bag.But work the device that rotates directive effect between wheel seat and the caster in the cardan wheel that existing case and bag use and be the hoodle circle, its structure as shown in fig. 1, in being arranged on by hoodle 30, the hoodle circle constitutes between bowl 20, the outer bowl 10, hoodle 30 rotates along its plane, internally bowl 20 and outer bowl 10 cause wearing and tearing, thereby case and bag also can produce the degree of wear that vertically extruding strengthens inside and outside bowl, the service life of reducing cardan wheel to the hoodle circle simultaneously.And this cardan wheel need scribble lubricating oil in hoodle circle periphery, and lubricating oil rolls between hoodle during use, and greasy dirt leaks out easily, and the noise that the friction of rolling between hoodle produces is big, and wheel is dumb when rotating.For addressing the above problem, in being 200720194849.2 Chinese patent, the patent No. mentioned a kind of cardan wheel that is used for case and bag, adopt the bearing that vertically rotates to replace the hoodle circle in this cardan wheel, but the structure of its whole cardan wheel some complexity also, dismounting is all inconvenient.

Summary of the invention

The utility model provides a kind of cardan wheel, and purpose is to solve the prior art problem, provide a kind of cardan wheel of simple in structure, easy accessibility, and this cardan wheel degree of wear is little, obtains service life prolonging.

The utility model technical scheme that adopts of dealing with problems is:

Cardan wheel includes wheel seat, caster, and the caster lower shaft is provided with wheel, it is characterized in that: be fixed with the bearing of vertical rotation on the described wheel seat, its wheel seat back side offers and is no less than 1 the fixed orifice that is used for wheel seat is fixed on the case and bag bottom; Caster upper end central part is fixed with rivet, and rivet inserts in the bearing wheel seat and caster are fixed together.

The beneficial effects of the utility model: this cardan wheel has reduced the part that uses in the total, not only makes the dismounting of cardan wheel become simpler, has also saved cost.

Description of drawings

Fig. 1 is the cardan wheel structural representation of prior art;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is the cutaway view of wheel seat;

Fig. 4 is the back view of wheel seat;

Fig. 5 is the cutaway view of caster.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Cardan wheel described in Fig. 2, Fig. 3, Fig. 4, Fig. 5 includes wheel seat 1, caster 2, and caster 2 lower shaft are provided with wheel 3.Be fixed with the bearing 5 of vertical rotation on the described wheel seat 1, wheel seat 1 back side offers and is no less than 1 the fixed orifice 4 that is used for wheel seat is fixed on the case and bag bottom, has offered 4 fixed orifices 4 in the present embodiment.Caster 2 upper end central parts are fixed with rivet 6, and rivet 6 inserts in the bearing 5 wheel seat 1 and caster 2 are fixed together.

When being installed on the case and bag in the cardan wheel, wheel 3 in advance axle be located at caster 2 bottoms, earlier 6 rivetings of the rivet on the caster 2 being advanced in the bearing 5 on the wheel seat 1 is fixed together caster 2 and wheel seat 1, thereby the fixed orifice 4 that again connecting element is passed successively the case and bag bottom and wheel seat 1 back side is fixed together wheel seat 1 and case and bag bottom, and the whole erection process finishes.The unloading process of its cardan wheel is opposite with above-mentioned installation process.

Whole cardan wheel part is few, simple in structure, not only makes the dismounting of cardan wheel become simpler, has also saved cost.

Claims

1. cardan wheel includes wheel seat, caster, and the caster lower shaft is provided with wheel, it is characterized in that: be fixed with the bearing of vertical rotation on the described wheel seat, its wheel seat back side offers and is no less than 1 the fixed orifice that is used for wheel seat is fixed on the case and bag bottom; Caster upper end central part is fixed with rivet, and rivet inserts in the bearing wheel seat and caster are fixed together.
