Abstract
The utility model relates to a check valve for footwear, which comprises a valve body and a ball body. The ball body is arranged in the valve body; the upper and lower ends of the valve body are coaxially and fixedly provided with an upper cover and a lower cover respectively; the upper cover and the lower cover are both provided with through-holes; and the diameter of the ball body is greater than that of the upper part of the valve body so as to seal the valve body. The check valve for footwear is embedded into the sunken position of a sole for playing the double roles in water proofing and ventilation. When the wearer treads water, because of the effect of the water pressure, the ball body moves upwards to seal the valve body for achieving the function of sealing; When the wearer lifts his legs off the ground, because the effect of gravity, the ball body moves downwards to open the valve body for playing the role in water drainage and ventilation; and the check valve for footwear is particularly suitable for mountaineering shoes or military shoes.
Description
Technical field
The utility model belongs to the footwear of daily living article, especially a kind of footwear one-way valve.
Background technique
Shoes are indispensable daily necessitiess that people walk, and people are in when walking, and pin is to-and-fro motion in footwear, can produce air pressure in the footwear body, along with the rising of air pressure can cause the rising of temperature, thus can breed bacteria in pin, fungi etc., and pin is damaged.For this reason, some uppers of a shoe are provided with through hole, to reduce footwear internal air pressure, ventilation and heat; And the ventilation effect of upper of a shoe is relatively poor.In addition, this through hole can't be prevented entering of sealing in ventilative, understand harmful foot and shoes equally.Especially climbing boot or military footwear, it is had relatively high expectations to ventilative and waterproof, and existing footwear construction can't have the waterproof and breathable function concurrently.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, footwear one-way valve of having the waterproof and breathable function concurrently is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of footwear one-way valve comprises valve body and spheroid, and spheroid places in the valve body, at coaxial loam cake and the lower cover of being fixed with of the upper/lower terminal of valve body, loam cake and under cover the uniform through hole that is shaped on, the diameter of spheroid greater than valve body top to seal valve body.
And, the uniform claw that is shaped on the loam cake inner edge at loam cake and the valve body place of installing.
And, in the inner edge curls inward at lower cover and the valve body place of installing strengthening sleeve is housed.
Advantage of the present utility model and beneficial effect are:
The footwear one-way valve that the utility model is related, peace are embedded in the sole recess and play waterproof and ventilative double action.The wearer because the effect of hydraulic pressure moves on the spheroid and seals valve body, reaches the effect of sealing when stepping on water; When the wearer lifts the pin built on stilts, because the effect of gravity, spheroid moves down opens valve body, plays the effect that sluices with ventilative, is particularly suitable for climbing boot or military footwear.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to the structure sectional view.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of footwear one-way valve is made of loam cake 1, valve body 4, lower cover 6, spheroid 5, and the coaxial upper/lower terminal that is packed in valve body of loam cake and lower cover is built-in with a spheroid at valve body, and the diameter of this spheroid can be sealed valve body top.Loam cake and under cover the uniform through hole 2,7 that is shaped on, this through hole is made is shaped as shapes such as circular hole (as present embodiment), elliptical aperture.The uniform claw 3 that is shaped on the loam cake inner edge at loam cake and the valve body place of installing, this claw is used to assemble the usefulness of this one-way valve in sole.
In order to improve the soundness of one-way valve, strengthening sleeve 8 is housed in the inner edge curls inward at lower cover and the valve body place of installing.
Working principle of the present utility model is:
Will be at one or more this one-way valve of sole recess peace embedding, loam cake is in the footwear body, and lower cover maintains an equal level at sole and with sole or is more lower slightly.When the wearer when stepping on water, because the effect of hydraulic pressure moves on the spheroid and seals valve body to reach the effect of sealing; When the wearer lifts the pin built on stilts, because the effect of gravity, spheroid moves down opens valve body, plays the effect that sluices with ventilative.
Claims (3)
1. a footwear one-way valve comprises valve body and spheroid, and spheroid places in the valve body, it is characterized in that: at coaxial loam cake and the lower cover of being fixed with of the upper/lower terminal of valve body, loam cake and under cover the uniform through hole that is shaped on, the diameter of spheroid greater than valve body top to seal valve body.
2. footwear one-way valve according to claim 1 is characterized in that: the uniform claw that is shaped on the loam cake inner edge at loam cake and the valve body place of installing.
