Abstract

A kind of inflation footwear, it is made up of rubber soled shoes, charge valve, inflation sebific duct, O-ring seal; Charge valve is made of large, medium and small cylinder, and in, the axis of big column is vertical configuration, axis little, big column is concentric shape, one thin neck section is arranged and be provided with radially through hole on this thin neck section at the connecting portion of large and small cylinder; In, the center of big column is provided with the central through hole of UNICOM, and the through hole of central through hole and thin neck section is UNICOM's shape; In its sole of rubber soled shoes, be provided with passage, be provided with communication passage and extraneous through hole at the arch of the foot position of sole; On its thin neck section of charge valve, be with the O-ring seal of control inflation sebific duct air inlet; Be connected with in the passage that places sole that the inflation sebific duct of charge valve coincide; When the inflation sebific duct unaerated in the passage, the elasticity of sole is constant all the time; After the through hole by its thin neck section of charge valve injected the inflation sebific duct with pressed gas, dilated inflation sebific duct will make the elasticity of sole change.

Description

A kind of inflation footwear

Affiliated technical field

The utility model relates to a kind of footwear, especially can change a kind of footwear of its elastic stage after the sole inflation.

Background technology

As everyone knows, everyone needs to wear footwear for we, and along with different purposes people propose different functional requirements again to footwear.For example, the students of liking playing basketball is just liked the footwear that flexible and its elasticity of a kind of sole can change according to different requirements again.Though someone has released the invention with spring sole, owing to can't regulate its elasticity, invention fails to obtain people's extensive approval.Based on so a kind of consideration, but the present invention release a kind of have the inflation sebific duct and its inner gas pressure as its flexible sole of inflation tyre regulated at will.Find no the invention of identical structure by retrieval.

Summary of the invention

The objective of the invention is: release the footwear that a kind of its sole can arbitrarily be inflated.

A kind of inflation footwear, it is made up of rubber soled shoes (1), charge valve (2), inflation sebific duct (3), O-ring seal (4);

In its sole of rubber soled shoes (1) (11), be provided with the passage (13) of annular, be provided with in the side at its arch of the foot position of sole (11) and be used for communication passage (13) and extraneous through hole (12);

The overall structure of charge valve (2) is made of big column (21), middle cylinder (22), small column (23), and the axis that the axis of the axis of middle cylinder (22) and big column (21) is vertical configuration, small column (23) is concentric shape with the axis of big column (21), a thin neck section (24) is arranged and be provided with radially through hole (27) on this thin neck section (24) at the connecting portion of big column (21) and small column (23); Be provided with central through hole (25) and central through hole (26) successively at the center of middle cylinder (22) and big column (21), and central through hole (25), central through hole (26) and through hole (27) are UNICOM's shape;

Inflation sebific duct (3) one end is opening-like, the other end is closed, and its openend tightly is enclosed within on the big column (21);

O-ring seal (4) is placed on the thin neck section (24), and is hedged off from the outer world by flexible sebific duct (3) inner chamber of will inflating of the method for airtight through hole (27).

Beneficial effect of the present invention: to a kind of footwear that people provide a kind of elasticity of its sole to regulate, these footwear provide bigger facility for people's sports.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model structural representation.

Fig. 2 is that F---F is to view.

Fig. 3 is its structure enlarged drawing of the part shown in the I among Fig. 2.

Among each figure, 1, rubber soled shoes, 11, sole, 12, through hole, 13, passage, 2, charge valve, 21, big column, 22, middle cylinder, 23, small column, 24, thin neck section, 25, central through hole, 26, central through hole, 27, through hole, 3, the inflation sebific duct, 4, O-ring seal.

The specific embodiment

The utility model as shown in Figure 1 is made up of rubber soled shoes (1), charge valve (2), inflation sebific duct (3), O-ring seal (4); As shown in Figure 3, on its big column of charge valve (2) (21) that an end of inflation sebific duct (3) tightly is enclosed within; O-ring seal (4) is placed on the thin neck section (24), and by its elastic restoring force through hole (27) is sealed, and makes the inner chamber and the external world of inflation sebific duct (3) be isolated shape; As shown in Figure 2, the charge valve (2) that tightly is with inflation sebific duct (3) and O-ring seal (4) on it respectively places in the through hole (12) of sole (11), and what inflation sebific duct (3) was coincide places in the passage (13).

During inflation sebific duct (3) unaerated in placing passage (13), the elasticity of its sole of rubber soled shoes (1) (11) is exactly himself intrinsic elasticity of sole (11); When people will change the elasticity of sole (11), at first, the central through hole of using in the air tube insertion charge valve (2) of inflating (25) to basketball; Then by inflator to central through hole (26) injection pressure gas, this pressed gas by through hole (27) will be placed on the thin neck section (24) O-ring seal (4) jack-up and to inflation sebific duct (3) the unidirectional gas that is injected with pressure, in the middle of the process of this lasting air inlet, inflation sebific duct (3) constantly expands, and the passage (13) that is subjected to the expansive force effect just can change the elasticity of sole (11).As the air pressure that changes in the tire, the elasticity that just can change tire is the same.

In addition, consider the injection effect of air inlet, charge valve (2) adopts elastomeric material to be made as, and the aperture size of its central through hole of charge valve (2) (25) is less than the external diameter of air tube.

Claims (1)

1, a kind of inflation footwear is characterized in that: it is made up of rubber soled shoes (1), charge valve (2), inflation sebific duct (3), O-ring seal (4); In its sole of rubber soled shoes (1) (11), be provided with passage (13), be provided with communication passage (13) and extraneous through hole (12) in the side at sole (11) arch of the foot position; Inflation sebific duct (3) coincide places passage (13).
