The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a one-way inflation valve, includes the valve body, the valve body be cylindricly, its outside is provided with the mounting panel of the radial extension of round, the inboard bottom plate of valve body open between two parties and have the centre bore, the centre bore be provided with the inflation hole all around, the bottom of the inboard bottom plate of valve body install the valve block of plugging up the inflation hole, the connecting rod at the upside middle part of valve block pass the centre bore fixed.

As a supplement to the technical scheme of the utility model, the valve body outside of mounting panel upside on open and to have the round caulking groove.

As right technical scheme a supplement, still include the shield, the one end of shield pass through the connecting strip and cup joint the go-between in the caulking groove and link to each other.

Furthermore, the inflation holes are fan-shaped and are evenly arranged around the central hole in four shapes.

Furthermore, the lower end of the valve body is axially provided with an inner groove, and the top surface of the inner groove is a conical surface and is matched with the upper end surface of the valve plate.

Furthermore, the inner hole at the upper end of the valve body is in a cone shape with a large upper end and a small lower end.

Furthermore, the other end of the dustproof cover is radially provided with a shifting plate, and one side of the shifting plate is provided with a plurality of anti-skid convex strips.

Has the advantages that: the invention relates to a one-way inflation valve which is simple in structure, few in parts, free of the use of a spring, good in sealing effect and capable of achieving one-way inflation by utilizing the elasticity of a valve plate, can be installed in an inflatable waterproof backpack and other inflatable articles, and is wide in application field.

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.

As shown in fig. 1-3. The utility model discloses embodiment relates to a one-way inflation valve, including valve body 1, valve body 1 be cylindricly, its outside is provided with the mounting panel 7 of the radial extension of round, the inboard bottom plate of valve body 1 open between two parties and have centre bore 6, centre bore 6 be provided with all around and aerify hole 14, the bottom of the inboard bottom plate of valve body 1 install the valve block 9 that will aerify the 14 shutoff of hole, connecting rod 5 at the upside middle part of valve block 9 pass centre bore 6 fixed.

With this patent the inflation valve install on aerifing waterproof knapsack, when using inflating apparatus or mouth to aerify towards valve body 1, the edge entering that the valve block 9 can be blown open to the air current, in case the air current stops, resumes the normal position under the elastic action of valve block 9, blocks up inflation hole 14, realizes self-sealing.

7 the valve body 1 outside of upside of mounting panel on open and to have the round caulking groove 3, still include shield 2, the one end of shield 2 link to each other through connecting strip 11 and the go-between 10 of cup jointing in caulking groove 3, caulking groove 3 conveniently carries out the axial spacingly to go-between 10, prevents that shield 2 from losing.
