Description

Technical Field

[0001] The invention relates to an inflator nozzle for tires, balls, life buoys, air cushions and other products, which is essentially an air intake one-way valve, and in particular to a new British air nozzle, which can be used in various types of products with an inflator nozzle structure. Background Art

[0002] In contemporary society, the use of air nozzles is very popular, and the British air nozzle is one of them, which is commonly found on bicycle inner tubes.

[0003] Because the air tightness of the British gas valve is not as good as that of the American gas valve and the French gas valve, and the rubber tube is prone to aging and failure, causing air leakage, it is used less and less and gradually withdraws from the stage of history. Summary of the invention

[0004] Aiming at the defects of poor air tightness of British gas nozzles and easy aging and failure of rubber tubes, the inventor has invented an improved new British gas nozzle after long-term research and experiments, which completely solves the defects of poor air tightness of British gas nozzles, easy aging and failure of rubber tubes, and air leakage. Compared with American gas nozzles and French gas nozzles, it also has the advantage of no air leakage when the inflation connector is unplugged, which is particularly suitable for occasions where precise inflation pressure is required or the inflation volume is small.

[0005] The present invention specifically adopts the following scheme:

[0006] A new type of British gas nozzle, including a gas nozzle body, a core body, and a leather tube. The new type of British gas nozzle also includes an inner top screw. The gas nozzle body is a tubular structure. The outer cone surface provided in the middle section of the core body matches the inner cone surface provided in the middle section of the inner hole of the gas nozzle body. The leather tube is made of elastic material, which is sleeved outside the core body and clamped between the gas nozzle body and the core body. The inner top screw is provided with an outer thread matching the inner thread of the gas nozzle body. A vent is provided in the center of the inner top screw. The inner top screw and the core body are arranged longitudinally in the gas nozzle body front and back, the inner top screw is close to the outside, and the core body is close to the inside. A vent is also provided in the center of the core body and is connected with the vent of the inner top screw. The vent in the center of the core body is wrapped and closed by the leather tube. The manufacturing materials of the leather tube include elastic plastic and rubber, usually high elastic rubber, silicone rubber, fluororubber, and latex.

[0007] Rotate the inner top screw to move it inward, and the outer conical surface of the core body presses against the inner conical surface of the air nozzle body, compressing the leather tube to form the first air seal.

[0008] The novel English-style gas nozzle also includes a sealing cover, and the outer cylindrical surface of the corresponding gas nozzle body is provided with an external thread matching the internal thread of the sealing cover.

[0009] The sealing cover is provided with a circular or annular sealing gasket, which is lined in the sealing cover and sandwiched between the air nozzle body and the sealing cover. The sealing gasket is made of elastic material, and the materials used to make the sealing gasket include elastic plastic and rubber, usually high elastic rubber, silicone rubber, and fluororubber. The sealing gasket is in the shape of a circular gasket or annular gasket.

[0010] When the sealing cover is tightened, the sealing gasket sandwiched between the air nozzle body and the sealing cover is compressed to form a second air seal.

[0011] The outer thread surface of the gas nozzle body is coated with an elastic sealing material and is sandwiched between the outer thread of the gas nozzle body and the inner thread of the cover. The elastic sealing material is usually elastic polytetrafluoroethylene.

[0012] When the sealing cap is tightened, the elastic sealing material sandwiched between the external thread of the gas nozzle body and the internal thread of the sealing cap is compressed to form a third gas seal.

[0013] The air nozzle body is installed in a hole opened for the inflated object on the thin wall. One end of the inner side of the air nozzle body is enlarged into a disc shape, and together with the clamping nut sleeved outside it, the thin wall of the inflated object is sandwiched in the middle. The inflated objects include tires, balls, lifebuoys, hovercrafts, and functional air cushions. That is, the application objects of the new British air nozzle include tires, balls, lifebuoys, hovercrafts, and functional air cushions. The functional air cushion refers to air cushion products such as inflatable mattresses, inflatable seat cushions, and air cushion shoes.

[0014] A sealing gasket is sandwiched between the air nozzle body and the thin wall of the inflated object, or between the thin wall of the inflated object and the compression nut. The sealing gasket is made of elastic plastic or rubber, usually high elastic rubber, silicone rubber, or fluororubber.

[0015] The inflated object may also be designed to be in the shape of a sleeve that is recessed inwards or protrudes outwards at the location where the novel English gas nozzle is installed, and the installation of the novel English gas nozzle is completed by inserting the novel English gas nozzle into the sleeve.

[0016] The tubular part of the core body and the leather tube is sleeved together, and has a wavy outer surface to enhance air tightness, and is provided with at least one radial vent hole; the radial vent holes of the core body are connected to its central vent hole; the port on the outward side of the central vent hole is provided with an internal thread for removing the core body.

[0017] The cross-sectional shape of the outer end of the inner top screw is matched with the end shape of the corresponding tightening tool, and is used to screw the inner top screw into the inner hole of the air nozzle body and press the core body inward along the axial direction. Specifically, the shapes of the inner top screw end include inner square, inner square, inner hexagon, outer square, outer square, and outer hexagon.

[0018] The orifice portion of the outer end of the air nozzle body is not provided with an internal thread, and has an internal hexagonal cross section, which fits with another tightening tool with a corresponding external hexagonal end shape, and is used to stop the air nozzle body from rotating when tightening the compression nut.

[0019] The core body and the inner top screw may also be an integral structure, and the outer circumferential surface of the corresponding core body is provided with an outer thread matching the inner thread of the air nozzle body. In this case, the new English air nozzle can only form an air sealing structure.

[0020] The advantages of the present invention are:

[0021] 1. Compared with the traditional British gas nozzle, the new British gas nozzle of the present invention has three air seals from the inside to the outside, and has better air tightness.

[0022] 2. The leather tube, sealing gasket and sealing spacer of the present invention are made of high-elastic rubber, silicone rubber or fluororubber and are not prone to aging and failure.

[0023] 3. Compared with the American gas nozzle and the French gas nozzle, the present invention has the advantage of preventing air from escaping the moment the inflation connector is unplugged, and is particularly suitable for occasions requiring precise inflation pressure or a small inflation volume.

[0024] 4. The invention has a light structure, reliable operation, simple corresponding manufacturing process, low cost, and is convenient for large-scale production and popular use. BRIEF DESCRIPTION OF THE DRAWINGS
