Puncture-proof tires

Abstract

The present invention provides a puncture-proof tire, which belongs to the technical field of automobile tires, and is intended to solve the problem that the existing automobile inner tube is a single inflatable airbag. Once the airbag is punctured, the entire tire loses its function and needs to be removed for repair, which affects the normal driving of the vehicle. It includes a rubber tire and a valve nozzle, the valve nozzle is arranged on the rubber tire and is connected to the rubber tire, and is characterized in that a high-pressure air distribution pipe is arranged on the outer ring of the rubber tire, and a plurality of rubber bladders are arranged on the high-pressure air distribution pipe, and the rubber bladders are connected to the high-pressure air distribution pipe. By arranging a plurality of rubber bladders on the outer ring of the inner tube, the rubber bladders and the rubber tire are inflated respectively through the valve nozzles arranged on the rubber tire, each rubber bladder serves as an independent air storage space, and a plurality of rubber bladders form a protective layer. When one of the rubber bladders is punctured, the remaining rubber bladders can still provide support force, so that the vehicle can drive normally.

Description

Technical Field

[0001] The invention relates to the technical field of automobile tires, in particular to puncture-proof tires. Background Art

[0002] At present, cars, as a common means of transportation, provide convenience for people's travel. As an important component of some vehicle tires, automobile inner tubes have a great impact on the normal driving of cars. Vehicles often have problems with tires being punctured and leaking during driving. Existing automobile inner tubes are mostly single-layer structures. Once the inner tube is punctured and the tire is leaking, it is necessary to remove the wheel and remove the inner tube to repair the tire, otherwise the vehicle will lose its ability to drive normally; tire removal and repairing require relatively professional tools and certain operating experience, and it is difficult for ordinary people to repair the inner tube by themselves. When encountering the problem of inner tube puncture and leaking in remote areas, if the tire cannot be repaired in time, it will have a great impact on the travel time, and even dangerous situations where people are trapped. Summary of the invention

[0012] The rubber tire 1, the rubber bladder 2, the high-pressure air distribution pipe 3, the valve mouth 4, the mounting tube 41, the inflation nozzle 42, the valve core 43, the diverter 44, the first air guide pipe 45, and the second air guide pipe 46. DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0014] like Figure 1 to Figure 2As shown, the puncture-proof tire comprises a rubber tire 1 and a valve 4, characterized in that a high-pressure air distribution pipe 3 is provided on the rubber tire 1, and the valve 4 is fixedly arranged on the high-pressure air distribution pipe 3 and communicated with the high-pressure air distribution pipe 3; a plurality of rubber bladders 2 are provided on the high-pressure air distribution pipe 3, and the rubber bladders 2 are communicated with the high-pressure air distribution pipe 3; the valve 4 comprises a mounting tube 41, an inflation nozzle 42, a valve core 43, a diverter 44, a first air guide pipe 45 and a second air guide pipe 46; the valve core 43 is placed in the inflation nozzle 42, the inflation nozzle 42 is rotatably arranged in the mounting tube 41, the diverter 44 is fixedly arranged in the mounting tube 41, and the bottom end of the inflation nozzle 42 and the diverter 46 are connected. 4; a first air vent is provided at the bottom of the inflation nozzle 42, two second air vents are provided in the diverter 44, one end of the first air guide tube 45 is placed in one of the second air vents, and the second air vent and the first air guide tube 45 are interference fit; the second air guide tube 46 is placed at the bottom of the diverter 44 and communicated with the other second air vent; the mounting tube 41 is placed on the high-pressure air distribution tube 3, the bottom of the mounting tube 41 is located in the high-pressure air distribution tube 3, the top of the mounting tube 41 is located outside the high-pressure air distribution tube 3, and the second air guide tube 46 is located in the high-pressure air distribution tube 3; the front end of the first air guide tube 45 passes through the high-pressure air distribution tube 3 and is communicated with the rubber tire 1.

[0015] Furthermore, the rubber bladder 2 includes a bladder body and a connecting nozzle disposed on the bladder body, and the bladder body and the connecting nozzle are connected; a round hole matching the connecting nozzle is provided on the high-pressure air distribution pipe 3, and the bladder body is connected to the high-pressure air distribution pipe 3 through the connecting nozzle.

[0016] When in use, the inflation nozzle 42 is rotated to connect the first vent hole with the second vent hole connected to the second air duct 46, and the inflation nozzle 42 is inflated. The gas passes through the valve core 43, the first vent hole, the second vent hole and the second air duct 46 and enters the high-pressure air distribution pipe 3. The high-pressure air distribution pipe 3 inflates several connected rubber bladders 2 to make the rubber bladders 2 become independent air bags with a relatively high air pressure inside. After the rubber bladders 2 are completely inflated, the inflation nozzle 42 is rotated to connect the first vent hole with another second vent hole, and the high-pressure gas enters the tire 1 through the second vent hole and the first air duct 45 to complete the inflation of the tire 1. After the inflation is completed, the pressure in the rubber bladder 2 and the high-pressure air distribution pipe 3 is greater than the pressure in the tire 1, and the rubber bladder 2 provides support for the outer tire; after all the inflation is completed, the gas volume in the high-pressure air distribution pipe 3 is much smaller than the gas volume in the tire 1 and the rubber bladder 2, and the tire 1 and the rubber bladder 2 expand and contact and squeeze each other; the diameter of the high-pressure air distribution pipe 3 remains unchanged, and when the high-pressure gas in the high-pressure air distribution pipe 3 leaks, it will not be deformed due to pressure, and will not affect the normal operation of the tire.

[0017] The design of the present invention is to arrange multiple rubber bladders on the outer ring of the inner tube, and to inflate the rubber bladders and the rubber tire respectively through the valve nozzles arranged on the rubber tire. Each rubber bladder serves as an independent air storage space, and several rubber bladders form a protective layer. When one of the rubber bladders is punctured, the remaining rubber bladders can still provide support force, so that the vehicle can run normally.

[0018] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
