Abstract

The utility model relates to a streamline body and eccentricity retaining universal wheel, which comprises a flat rolling ball. The rolling ball is fixed between the both sides of a support frame through a shaft, the support frame is provided with a retaining member which is positioned between the support frame and the rolling ball and is used for controlling a rolling wheel to stop or rotate, the shaft has an eccentric distance with the middle line of the support frame, and the rolling ball and a contact surface contact in a surface mode. When an object needs to stop, a retaining state can be kept; the utility model has the characteristics of flexible operation and high stability.

Description

Fairing Camlock cardan wheel

The utility model relates to a kind of universal rolling wheel, particularly a kind of fairing Camlock universal rolling wheel.

Existing universal rolling wheel comprises not to be had the axle universal rolling wheel and a universal rolling wheel is arranged, and is made up of the bracing frame on a roller, roller top substantially.Do not have the axle universal rolling wheel and block wheel easily, it is not too convenient to turn round; Have a universal rolling wheel and ground to adopt point to contact, object is not too steady in moving; When the object needs are static, can not maintain the lock status.

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, proposes a kind of fairing Camlock cardan wheel, and roller contacts with contact surface employing face, when object needs can to maintain the lock status when static, have go slick, the characteristics of good stability.

The utility model comprises the roller of a flats, and roller disposes a locking piece by axle and support phase configuration between roller and the support, and a support and a base plate link, and dispose ball between support and the base plate, and axle has an eccentric distance with the support center line.

Fig. 1 is a lateral plan of the present utility model.

Fig. 2 is a cutaway view of the present utility model.

Fig. 3 is the constructional drawing of locking piece (8).

Fig. 4 is another embodiment of the present utility model.

Fig. 5 is the cutaway view of another embodiment.

Below in conjunction with accompanying drawing structural principle of the present utility model and principle of work are done detailed explanation.

Referring to Fig. 1,2, the utility model comprises the roller (11) of a flats, roller (11) is fixed between the both sides of support (5) by axle (10), and can rotate around axle (10), support (5) links by rivet (1) and a base plate (2) and last pearl bowl (3), disposes pearl bowl (3) between base plate (2) and the support (5), and support (5) top downside disposes down pearl bowl (7); Dispose ball (4), (6) respectively between upper and lower pearl bowl (3), (7) and the support (5); Support (5) is gone up by attaching parts (9) configuration one locking piece (8); Locking piece (8) is positioned between support (5) and the roller (11), and an end can rotate around attaching parts (9), and an other end of locking piece (8) can be stuck on the axle (10); Axle (10) has an eccentric distance L with the center line of support (5).

Optimum dimension of the present utility model is: eccentric distance L=9～24 millimeter; Height h=50～200 millimeter of axle (10); Diameter D=50～200 of roller (11) millimeter.

Referring to Fig. 3, locking piece (8) is " colluding " shape, and the one end can be fixed on the support (5), and the other end can be stuck on the axle (10).

Referring to Fig. 4,5, remove base plate (2) among this embodiment, directly go up configuration one screw rod (12) on last pearl bowl (3) top and rivet (1).

During use, the utility model is fixed on the object by base plate (2) or screw rod (12).When the object needs are mobile, promote object, roller (11) can rotate around axle (11) under the effect of external force; Simultaneously, support (5) also can rotate around rivet (1), turns to function thereby finish.When object fixedly the time, pull locking piece (8), it is stuck on the axle (10), then roller (11) is stuck.

The utlity model has following characteristics:

(1) roller (11) is face with ground or other contact surface and contacts good stability;

(2) do not need when mobile available locking piece (8) locking when object;

(3) axle (10) has an eccentric distance with the center line of support (5), is the streamline shape, has not only overcome card wheel problem, and has had attractive in appearance, generous characteristics.
