A kind of shoes
Technical field
The present invention relates to a kind of shoes.
Background technology
Shoes are the necessitys in daily life, can play the effect of protection pin.In time walking in scree or sand heap, shoes are easily toward sinking, meanwhile, sand can enter into shoes inside from the opening part of shoes, under finally resting on sole, there is sand that people can be made to feel very uncomfortable in shoes, and can sole be galled, current processing mode only have shoes have been taken off after pour out sand, put on shoes again, very inconvenient, when especially walking in desert, sand everywhere, after entering sand in shoes, take off shoes and pour out sand, a few step sand of going further can enter into again in shoes, above-mentioned method cannot be dealt with problems completely, and sand temperature is higher, even more serious to the injury of sole.
Summary of the invention
The present invention is directed to prior art deficiency, provide a kind of shoes, it can while walking; sand in discharge shoes fast and automatically, protection sole, and its working method is continual; ventilate below shoes simultaneously, avoid pin sweat to accumulate, eliminate peculiar smell.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of shoes, comprise sole and vamp, described vamp comprises toe lasting and rear side, described sole sidewall is scalable, cavity is offered in described sole, described cavity inner bottom surface is provided with air bag, described air bag offers air admission hole and venthole, arc is provided with above described air admission hole, described arc offers one number service hole, mutually align with described air admission hole and be communicated with in described one number service hole, and described arc is by side, and to described one number service hole, arc is downward gradually, described sole upper side offers several apertures being communicated with described cavity, the trailing flank of described sole offers No. two through holes.
When sand enters in shoes, sand drops on arc by aperture, again along with the inclined-plane of arc is slipped in air bag, during walking, after shoes touch ground, and sole sidewall is scalable, by the impact of human bady gravitational, sole is squeezed contraction, air bag is crushed, gas is discharged from venthole with sand, after shoes leave ground, sole is upheld, negative pressure in air bag, gas is by being drawn in air bag outside air bag, sand now in shoes is inhaled in air bag, that is sand is on the one hand by the impact of gravity, be slipped in air bag from arcwall face, be inhaled in air bag by the impact of air bag negative pressure on the other hand.
In technique scheme, described No. two through holes are rotatably connected to capping.Capping is set, can prevents from splashing the water droplet come and enter in air bag, ensure in air bag always dry, avoid too moistly in shoes causing harmful effect to pin.
The present invention compared with prior art, has following beneficial effect: the present invention can while walking, the sand in discharge shoes fast and automatically; protection sole, and its working method is continual, ventilates below shoes simultaneously; avoid pin sweat to accumulate, eliminate peculiar smell.Capping is set, can prevents from splashing the water droplet come and enter in air bag, ensure in air bag always dry, avoid too moistly in shoes causing harmful effect to pin.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail: see Fig. 1, a kind of shoes, comprise sole 1 and vamp 2, described vamp 2 comprises toe lasting 21 and rear side 22, described sole 1 sidewall is scalable, sole 1 sidewall can adopt rubber or have flexible material and make, as long as enable sole flexible up and down.Cavity 3 is offered in described sole 1, described cavity 3 inner bottom surface is provided with air bag 4, air bag 4 can be fixed with cavity 3 inwall, prevent air bag 4 from moving left and right, described air bag 4 offers air admission hole 41 and venthole 42, air admission hole 41 and venthole 42 all can arrange check valve, air admission hole 41 only allows to enter, venthole 42 only allows away, arc 5 is provided with above described air admission hole 41, described arc 5 offers one number service hole 51, mutually align with described air admission hole 41 and be communicated with in described one number service hole 51, air bag 4 cannot move left and right, ensure that to align all the time with air admission hole 41 in one number service hole 51.And described arc 5 is by side, and to described one number service hole 51, arc is downward gradually, described sole 1 upper side offers several apertures 11 being communicated with described cavity 3, and sole 1 upper side offers several grooves 14, groove 14 edge is arc, all apertures 11 are all arranged in corresponding groove 14, arranging groove 14 can facilitate sand to drop in aperture, avoids sand to be pushed down cannot drop from aperture 11 by sole.The trailing flank of described sole 1 offers No. two through holes 12.
Described No. two through hole 12 places are rotatably connected to capping 13.Capping 13 is set, can prevents from splashing the water droplet come and enter in air bag 4, ensure in air bag 4 always dry, avoid too moistly in shoes causing harmful effect to pin.
When sand enters in shoes, sand drops on arc 5 by aperture 11, again along with the inclined-plane of arc 5 is slipped in air bag 4, during walking, after shoes touch ground, and sole 1 sidewall is scalable, by the impact of human bady gravitational, sole 1 is squeezed contraction, air bag 4 is crushed, gas is discharged from venthole 42 with sand, after shoes leave ground, sole 1 is upheld, negative pressure in air bag 4, gas is by being drawn in air bag 4 outside air bag 4, sand now in shoes is inhaled in air bag 4, that is sand is on the one hand by the impact of gravity, be slipped in air bag 4 from arc 5, be inhaled in air bag 4 by the impact of air bag 4 negative pressure on the other hand.
