Abstract
The utility model relates to a ventilation gas bag used in a shoe. The gas bag comprises an outer packing body of the gas bag, a T-shaped seal cover and two exhaust pipes, wherein the outer packing body is formed by a columnar casing part and a parabolic raised structure at the top end; the exhaust pipes are arranged on the same plane; the included angle between each exhaust pipe and the part of the columnar casing part, which intersects the exhaust pipe, is 90 degrees; the T-shaped seal cover is arranged at the lower part of the outer packing body of the gas bag; and a semicircular annular groove on the bottom side of the column body of the T-shaped seal cover is tightly matched with a projecting ring on the bottom side of the columnar casing part. The utility model has the benefits that the ventilation gas bag can prevent the inside compressed air from flowing out, has high air compression ratio and strong air flow; the shape of the gas bag after being compressed is matched with that of a heel, the structure is stable, the damping and massaging effects can be performed; the ventilation gas bag is made of pure rubber so that the use life is longer; and the ventilation gas bag has small structure, lighter weight and wider application range.
Description
Technical field
The utility model relates in a kind of footwear and is used to the parts of taking a breath, and uses Air change vesicle in specifically a kind of footwear.
Background technology
Air entry and exhaust outlet are communicated in air intake passage respectively to existing common footwear and the exhaust passage also is communicated with the footwear external world, shoes lumen respectively with respectively being provided with on the Air change vesicle, and air intake passage and exhaust passage are respectively equipped with breather cheek valve and exhaust check valve, as shown in Figure 2.For the sewage that prevents the footwear outside and dust by the reverse air bag that enters in exhaust passage, the aperture of exhaust passage is provided with smaller, is very easy to be stopped up by dust, just needs air bag to have than atmospheric pressure punching press from inside to outside could to recover conducting in case stop up; The piston cylinder operator that existing air bag generally is made up of pneumatophore and spool, pneumatophore bottom are provided with air entry and the exhaust outlet that inner chamber is communicated with, and spool is inserted in the pneumatophore and with airtight and is slidingly matched; Piston structure directly influences exhaust effect because air-tightness is relatively poor, so accuracy of manufacture requirement is very high, and service life is not long; In order to keep good stable, all pneumatophores all will partly be bumped in the heel of a shoe usually, after this part air bag intracavity space is difficult for extruding during walking, scavenging efficiency is low, in a single day the exhaust passage is stopped up by dust simultaneously, the compression ratio of air bag is lower, air pressure is low, is difficult to wash open the exhaust passage of obstruction.
The utility model content
At above defective, the utility model provides in the high footwear of a kind of simple in structure, long service life, compression ratio and use Air change vesicle, has the defective of this type of aspect with the solution prior art.
For achieving the above object, the utility model is by the following technical solutions:
Use Air change vesicle in a kind of footwear, comprise the outer inclusion of air bag, T shape seal cover and two blast pipes, the outer inclusion of described air bag is made up of the parabolic bulge-structure of cylindrical shell part and top, and described blast pipe is arranged at same horizontal plane and becomes 90 ° with cylindrical shell part intersection area angle respectively; The outer inclusion bottom of described air bag is provided with T shape seal cover, and described T shape seal cover is the cylindrical structure of discoid projection, and its upper end is provided with the capital end cambered surface that is the shape that sink; The semicircle shape annular groove that one circle is the shape that sink is set in the annulus of described T shape seal cover cylinder bottom side, and this groove and cylindrical shell part bottom side bulge loop carry out airtight being connected.
The utility model beneficial effect is: be the sagging circle shape groove of semicircle by the bottom annulus and carry out airtight the cooperation with outer inclusion bottom bulge loop, can prevent that the internal compression air from flowing out, the air compression ratio is big, air-flow anxious; Shape after the compression is consistent with calcaneal profile, and structure is firm, have the damping massage effect; The employing gum is made, and service life is longer; Structure is small and exquisite, lighter weight, the scope of application are wider.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is a cross-sectional view of using Air change vesicle in the described footwear of the utility model embodiment;
Fig. 2 is a structural representation of using Air change vesicle in the existing general footwear.
Among the figure: 1, the outer inclusion of air bag; 2, cylindrical shell part; 3, T shape seal cover; 4, blast pipe; 5, bulge loop; 6, semicircle shape annular groove; 7, capital end cambered surface.
The specific embodiment
Shown in Fig. 1-2, use Air change vesicle in the described footwear of the utility model embodiment, comprise and adopt the outer inclusion 1 of the integrated air bag of rubber injection mold, T shape seal cover 3 and two blast pipes 4 respectively, the outer inclusion 1 of described air bag is made up of the parabolic bulge-structure of cylindrical shell part 2 and top, and these cylindrical shell part 2 sides are provided with two blast pipes 4 and intersect and keep being communicated with cylindrical shell; Described blast pipe 4 is arranged at same horizontal plane and becomes 90 ° with cylindrical shell part 2 intersection area angles respectively; Outer inclusion 1 bottom of described air bag is provided with T shape seal cover 3, and this T shape seal cover 3 is inverted and is installed on outer inclusion 1 bottom side of air bag, and described T shape seal cover 3 is the cylindrical structure of discoid projection, and its upper end is provided with the capital end cambered surface 7 that is the shape that sink; The semicircle shape annular groove 6 that one circle is the shape that sink is set in the described T shape seal cover 3 cylinder bottom side annulus, and this groove carries out airtight the cooperation to prevent that air bag internal compression air from overflowing with cylindrical shell part 2 bottom side bulge loops 5; Described T shape seal cover 3 cylinder capital end cambered surfaces 7 and the paraboloidal inboard cambered surface in air bag outsourcing body 1 top, this two places cambered surface is the minute surface symmetry mutually.With compare with the structure of Air change vesicle in the existing general footwear, this airbag structure is the circle shape groove that semicircle sink by the bottom annulus to carry out airtight the cooperation bottom outer inclusion, can prevent that the outflow of internal compression air, air compression ratio are big, air-flow suddenly; Shape after the compression is consistent with calcaneal profile, and structure is firm, have the damping massage effect.
