Abstract
The utility model discloses a dual-purpose vehicle wheel which can be used on stairways and the flat ground. The utility model comprises a combined cam-shaped main wheel which is formed by connecting three cam blocks into a whole, wherein each of the cam blocks of the main wheel is connected with a large and a small auxiliary wheels by shafts. The utility model has the advantages of simple structure and convenient use, and not only can be used on the flat ground but also can be used on the stairways.
Description
The utility model relates to a kind of wheel.
Common wheel only is applicable to level walking, can not adapt to the upper and lower of ladder, existing these cat ladder wheels, and complex structure uses, installs inconvenience.
The purpose of this utility model is to provide a kind of can be suitable for ladder, the level land is dual-purpose, and ladder simple in structure, the dual-purpose wheel in level land.
Technical solution of the present utility model is:
One species stage, the dual-purpose wheel in level land, the difference of itself and prior art is: comprise the compound cam shape main wheel that is fused by three cam bits, all be connected with small one and large one two accessory whorls by axle on each cam bit of main wheel.
The utility model is simple in structure, and use, easy for installation both had been suitable for the level land and has used, and can be applicable to that again upper and lower ladder uses.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the configuration diagram of an embodiment of the utility model.
Fig. 2 is the A-A view of Fig. 1.
Fig. 3 is the B-B view of Fig. 1.
One species stage, the dual-purpose wheel in level land comprise the compound cam shape main wheel 1 that is fused by three cam bits, and three cam bits of main wheel 1 are connected with big accessory whorl 3,3a, 3b and little accessory whorl 2,2a, 2b by axle 4,4a, 4b and axle 5,5a, 5b respectively.Three cam bits rectangular distribution on whole main wheel.
Principle of work of the present utility model is: when wheel rolled on ladder, main wheel 1 forwarded the complete moving angle of D point for wheel to from the C point, and it is the full traverse of wheel to the difference of the distance in axle center that the D point deducts the C point to the distance in axle center, is equal to or greater than the height of a ladder.Wheel constantly changes position of the fulcrum in main wheel 1 rotation process, accessory whorl 2,3 revolves round the sun thereupon, and when accessory whorl 2,3 touched terraced ground or stepped wall, rotation formed friction of rolling and raises and make it light laborsaving while revolving round the sun for accessory whorl 2,3, finish the rising of a ladder, constantly circulation constantly upwards.
When roll in the ladder below, principle is same as described above, switched in opposite.
When on the level land, rolling, be leading by the big accessory whorl on any two cam bits on the main wheel 1 respectively, little accessory whorl supports rotation for the back and advances, and main wheel 1 is a support.
