Description

At the bottom of the interlayer compression ventilation type rubber plastic footwear

Technical field: the utility model relates to daily footwear boots articles for use field, is specifically related to the architecture advances at the bottom of the rubber plastic footwear.

Background technology: existing footwear boots based article, although the animal's leather that has generally adopted japanning after the tanning is as lining, gas permeability and aesthetic property all improve greatly, but some the footwear boots superficial layer lap seam system too thick (as sneakers, ripple footwear etc.) or the leg of a boot are too dark, for quite a lot of groups of people especially as the young man, because of the very prosperity of its sweat gland, or reason such as amount of exercise is very big, still can feel that foot's perspiration is difficult to volatilize away, the footwear inner product is wet, make the wearer produce feeling suffocated sensations such as discomfort, snugness of fit far away can be fully up to expectations.

Summary of the invention: at the above-mentioned shortcoming of prior art, technical problem to be solved in the utility model be to provide a kind of periodic pressure that produces can utilize foot traffic the time to change to extract the wet gas in the footwear boots out footwear outer interlayer compression ventilation type rubber plastic footwear at the bottom of.

For this reason, technical solution of the present utility model is characterised in that: the main pressure-bearing position at sole is provided with the interlayer cavity body structure, the last aspect of this interlayer cavity body structure is a breathable hydrophily face, subsurface promptly is the rubber and plastic bottom surface, the rubber and plastic sidewall of this interlayer cavity body structure offers the one-way ventilating hole of linking up interlayer cavity inside/outside, also is provided with the air-permeable elastic supporting construction in described inside cavity.

Described main pressure-bearing position is forefoot position and heel position; Described breathable hydrophily face is the animal leather layer through the degreasing tanning that closely is cemented on the rubber and plastic sidewall; Described air-permeable elastic supporting construction is the uniform synthetic fibre tows pad of thickness.

Described one-way ventilating hole opening be positioned at cavity about on the two rubber and plastic sidewalls and on the heel, inside, one-way ventilating hole is provided with elastic membrane chip check valve.

When foot's walking movement, interlayer cavity body structure of the present utility model reduces volume because of being subjected to foot pressure, recovers volume because of removing to press; When cavity volume reduces, because the last aspect not animal leather layer through the degreasing tanning of japanning has absorbed moisture, have bigger air resistance, the gas of inside cavity can only discharge higher levels of humidity gas by on the two rubber and plastic sidewalls about sole and the one-way ventilating hole on the heel; And when cavity volume is recovered and expanded, because the check valve of establishing in one-way ventilating hole sealing, vacuum appears in the cavity, force cavity from thin degreasing not the pore of the animal leather layer of japanning with the gas inspiration inside cavity in the footwear boots ... thereby realize the circulation of bleeding with the outside pump drainage of moisture of footwear boots inside, and the moisture that can guarantee the outside can not enter in the cavity via the one-way ventilating hole and reach in the footwear, has improved the aridity in the footwear, has increased wearing comfortableness.

Description of drawings: now in conjunction with the accompanying drawings the utility model is explained.

Fig. 1 is the cross-sectional structure schematic diagram of the utility model midsole cavity.

Fig. 2 is the schematic perspective view of the utility model embodiment.

The specific embodiment: as shown in Figure 1: at the bottom of a kind of interlayer compression ventilation type rubber plastic footwear, it is characterized in that: the main pressure-bearing position at sole is provided with interlayer cavity 1, the last aspect of this interlayer cavity 1 is a breathable hydrophily face 2, subsurface promptly is the rubber and plastic bottom surface, offer the one-way ventilating hole 4 of linking up interlayer cavity 1 inside/outside on the rubber and plastic sidewall 3 of this interlayer cavity 1, also be provided with air-permeable elastic supporting construction 5 in described cavity 1 inside.

Described breathable hydrophily face 2 is the animal leather layers through the degreasing tanning that closely are cemented on the rubber and plastic sidewall 3; Described air-permeable elastic supporting construction 5 is the uniform synthetic fibre tows pads of thickness.

4 inside, one-way ventilating hole are provided with the valve block of flexible sheet 6 as check valve, and when external pressure was big, flexible sheet 6 was with 7 sealings of the air flue in the one-way ventilating hole 4; When internal pressure was big, flexible sheet 6 was unlocked at an easy rate, mediation air flue 7 and one-way ventilating hole 4.

As shown in Figure 2: described main pressure-bearing position is forefoot position and heel position, shows respectively as the hydrophilic film at the hydrophily face 2-1 at forefoot position and heel position and 2-2; Described one-way ventilating hole 4 openings be positioned at cavity about (not shown) on (side only is shown) and the heel on the two rubber and plastic sidewalls.
