Description

One third of shoe pad

Technical Field

The utility model relates to the field of insoles, in particular to a one third insole.

Background

The comfort requirements of people on shoes are continuously improved, and the main factor affecting the comfort of the shoes is insoles, and the insoles in the prior art have better sweat-discharging and ventilation functions so as to ensure that no peculiar smell can occur. With the continuous change of requirements, half sole insoles (refer to the patent of the utility model with publication number CN 106307800A) suitable for high-heeled shoes appear on the market, and the problem that the insoles are easy to slide in the shoes is solved; an heightening insole placed at the heel.

The heightening insole placed at the heel is mostly provided with a plurality of holes in the inside so as to increase the air permeability, but the air permeable structure can still be improved to a certain extent.

Disclosure of Invention

The present utility model aims to solve the above drawbacks and to provide a third insole to solve the above problems mentioned in the background art.

The object of the utility model is achieved by:

a one third insole comprises a heel pad, wherein a ventilation channel with two ends communicated is arranged in the heel pad, a plurality of ventilation holes are uniformly formed in the upper end of the ventilation channel, a plurality of arc protrusions are uniformly arranged in the ventilation channel, and a damping air bag is arranged in the middle of the heel pad.

In the above description, the lower end of the heel pad is provided with a silica gel anti-slip layer.

In the above description, the lower end surface of the silica gel anti-slip layer is provided with anti-slip patterns.

Further in the above description, the outer side of the heel pad is provided with rounded corners.

The utility model has the beneficial effects that: when using, place this heel gasket in the shoes back heel department, can use, in the walking in-process, under the downforce of foot, the heel gasket is sunken, makes ventilative passageway collapse and is in closed state, simultaneously at the sunken in-process of heel gasket, the air in the ventilative passageway is discharged to outside from ventilative passageway one end export, when the foot lifts up, the heel gasket rebound is expanded and is made ventilative passageway resume unblocked state to at rebound in-process that expands, outside air backfills heel gasket and ventilative passageway, with this ventilative circulation that forms.

Detailed Description

The utility model is described in further detail below with reference to the drawings and the detailed description.

Referring to fig. 1-4, an embodiment of a third insole comprises a heel pad 1, wherein a ventilation channel 101 with two conducting ends is arranged in the heel pad 1, sixty ventilation holes 102 are uniformly formed in the upper end of the ventilation channel 101, six arc protrusions 2 are uniformly arranged in the ventilation channel 101, a damping air bag 3 is arranged in the middle of the heel pad 1, and a rounding corner is arranged on the outer side of the heel pad 1. The heel pad 1 is constructed of sponge rubber.

The lower extreme of heel pad 1 is provided with silica gel anti-skidding layer 4, and the lower terminal surface on silica gel anti-skidding layer 4 is equipped with anti-skidding line.

When the heel pad 1 is used, the heel pad 1 can be placed at the heel position in the shoe for use, in the walking process, under the downward pressure of the foot, the heel pad 1 is sunken, so that the ventilation channel 101 is collapsed to be in a closed state, meanwhile, in the sunken process of the heel pad 1, air in the ventilation channel 101 is discharged to the outside from an outlet at one end of the ventilation channel 101, when the foot is lifted, the heel pad 1 is rebound and expanded to enable the ventilation channel 101 to recover to an unblocked state, and in the rebound and expanded process, the heel pad 1 and the ventilation channel 101 are backfilled with outside air to form ventilation circulation.

The present utility model is not limited to the preferred embodiments, but is intended to be limited to the following description, and any modifications, equivalent changes and variations in light of the above-described embodiments will be apparent to those skilled in the art without departing from the scope of the present utility model.
