A kind of luggage case of climbing stairs
Technical field
The present invention relates to a kind of instrument that can be used for travelling outdoors and carry luggage, be specifically related to a kind of luggage case of climbing stairs.
Background technology
At present, people go out whilst on tour with luggage nothing more than be exactly with luggage case or the back of the body knapsack, yet the place that station or overline bridge etc. have stair certainly will to be arrived when going away, this moment, luggage case just became a huge burden, carrying is very inconvenient when walking stair, violent vibrations also may damage some fragile articles in the chest, so just greatly reduce the efficient of trip and the happiness sense of travelling; And back of the body knapsack has just been said nothing of, although be not subjected to the impact of ground surface or terrain, at every moment allows the heavy burden state that lays oneself open to, and is very tiring.
Summary of the invention
Goal of the invention: the present invention provides a kind of purpose to be not to be subjected to the influence of topography in order to solve the deficiencies in the prior art, and the luggage case of labour-saving climbing stairs.
Technical scheme: in order to realize the foregoing invention purpose, the technical solution used in the present invention is:
A kind of luggage case of climbing stairs comprises casing, and described bottom half is provided with rotation driving wheel group, and described rotation driving wheel group is connected to bottom half by main shaft.
Described rotation driving wheel group is comprised of three supports, and the angle between the adjacent stent is 120 °, is provided with reinforcement between the support, and the end away from main shaft on the support is equipped with driving wheel;
Described bottom half is provided with the brake groove, and when the casing stop motion was upright, a driving wheel in the rotation driving wheel group dropped on and in the brake groove casing is not subjected to displacement and slides;
Described bottom half also is provided with feet.
Beneficial effect: compared with prior art, the present invention has had knapsack concurrently and has not been subjected to the laborsaving of the impact of landform and luggage case, the gravity of having used chest self when stopping does not block wheel and can run chaotically, and topples over for the accident that prevents center of gravity departs to cause, and has filled in the outer part a feet under chest.
Description of drawings
Fig. 1 is structural representation of the present invention.
1-rotation driving wheel group, 2-main shaft, 3-driving wheel, the 4-groove that brakes, the 5-feet.
The specific embodiment
The present invention will be described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of luggage case of climbing stairs comprises casing, and bottom half is provided with rotation driving wheel group 1, and rotation driving wheel group 1 is connected to bottom half by main shaft 2.Rotation driving wheel group 1 is comprised of three supports, angle between the adjacent stent is 120 °, be provided with reinforcement between the support, end away from main shaft 2 on the support is equipped with driving wheel 3, bottom half is provided with brake groove 4, when the casing stop motion was upright, a driving wheel 3 in the rotation driving wheel group 1 dropped on and in the brake groove 4 casing is not subjected to displacement and slides, and bottom half also is provided with feet 5.Three wheels will substitute work by turns when stair climbing, allow stair climbing also become as though walking upon flat ground.Then when chest is stopped, whole chest has to topple over and becomes uprightly, and one of them wheel of two groups all just in time has been crushed in the brake groove about then having, and luggage case just has been fixed like this, again displacement slip.
