Description

Technical Field

[0001] This utility model relates to the field of tire technology, specifically to an inflatable tire. Background Technology

[0002] The vast majority of existing tires are pneumatic tires. Their airtight layer or inner tube maintains the tire's shape and provides support after inflation. Currently, most tire airtight layer compounds use halogenated butyl rubber as the main gas barrier. Some tire manufacturers use dynamic vulcanized alloy films as the airtight layer, which offers advantages such as good airtightness and the ability to design a thinner, lighter layer, thus reducing tire weight and aligning with tire development trends. However, dynamic vulcanized alloy films have problems with poor adhesion to the tire carcass and significant differences in production processes compared to existing tire manufacturing. This necessitates large-scale modifications to tire production processes and equipment, meaning that production equipment for dynamic vulcanized alloy film airtight layers cannot be shared with halogenated butyl rubber airtight layer tires. Furthermore, dynamic vulcanized alloy film airtight layer tires are prone to air bubbles due to adhesion issues, resulting in high scrap rates. Additionally, the tire's inner ring needs support via steel wire rings, but these rings have poor deformation resistance, making tire assembly and disassembly inconvenient. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this invention is to provide an inflatable tire that solves the problems of poor adhesion of the vulcanized alloy film and the difficulty in disassembling the tire due to the steel wire ring.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic tire, comprising a tire, the tire including a carcass layer, a transition layer disposed on the inner side of the carcass layer, a gas barrier layer disposed on the inner side of the transition layer, a steel wire layer disposed on the outer side of the carcass layer, a tread layer disposed on the outer side of the steel wire layer, a steel mesh ring installed inside the tire, the steel mesh ring including a rubber tube and a steel wire mesh sleeve, the steel wire mesh sleeve being installed on the outer side of the rubber tube, the steel wire mesh sleeve being fixedly connected to the tire, and an inflation mechanism disposed inside the rubber tube.

[0005] Preferably, the transition layer is made of styrene-butadiene rubber, which can improve the connection strength between the gas barrier layer and the carcass layer.

[0006] Preferably, the gas barrier layer is made of a dynamic vulcanized alloy film, which can serve as the airtight layer of the tire.

[0007] Preferably, both the carcass layer and the tread layer are made of halogenated butyl rubber, which is a commonly used material for manufacturing tires.

[0008] Preferably, the inflation mechanism includes an inflation tube, an inflation tube fixedly connected inside the rubber tube, a support strip fixedly connected inside the inflation tube, two symmetrically distributed sliding pins slidably connected inside the support strip, a sealing cap fixedly connected to one end of each sliding pin, a spring provided on the outside of each sliding pin, the sealing cap slidably connected to the inflation tube, an external threaded ring fixedly connected to the outside of the inflation tube, the external threaded ring being connected to the inflation tube of the air pump via threads, and the sealing cap sealing the inflation tube.

[0009] Preferably, one end of the spring is fixedly connected to the support bar, the other end of the spring is fixedly connected to the sliding pin, and the external threaded ring is fixedly connected to the rubber tube. The spring can support the sliding pin through its elastic force.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model provides a dynamic vulcanized alloy film spanning the inner side of the tire carcass layer, with a rubber transition layer between the tire carcass layer and the dynamic vulcanized alloy film. The transition layer serves to bond the gas barrier layer to the tire carcass layer, reducing air bubbles between the tire carcass layer and the dynamic vulcanized alloy film during production, reducing defects, improving the durability of the finished product, and preventing delamination between the tire carcass layer and the dynamic vulcanized alloy film. This effectively improves the quality and yield of tires.

[0012] 2. This utility model adds a rubber tube, a wire mesh sleeve, and an inflation mechanism to the tire body. When disassembly is required, the gas inside the rubber tube can be released. After the gas is released, the rubber tube can deform. The deformation of the rubber tube and the wire mesh sleeve makes the tire easier to disassemble, thus making the tire easier to repair.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 A pneumatic tire includes a tire 10, which includes a carcass layer 3. A transition layer 2 is provided on the inner side of the carcass layer 3, and a gas barrier layer 1 is provided on the inner side of the transition layer 2. A steel wire layer 5 is provided on the outer side of the carcass layer 3, and a tread layer 6 is provided on the outer side of the steel wire layer 5. A steel mesh ring 4 is installed inside the tire 10. The steel mesh ring 4 includes a rubber tube 41 and a steel wire mesh sleeve 42. The steel wire mesh sleeve 42 is installed on the outer side of the rubber tube 41 and is fixedly connected to the tire 10. An inflation mechanism 7 is provided inside the rubber tube 41.

[0019] Please see Figure 1-3 The transition layer 2 is made of styrene-butadiene rubber. The transition layer 2 can improve the connection strength between the gas barrier layer 1 and the carcass layer 3. The gas barrier layer 1 is made of a dynamic vulcanized alloy film. The vulcanized alloy film can serve as the airtight layer of the tire 10. The carcass layer 3 and the tread layer 6 are both made of halogenated butyl rubber. Halogenated butyl rubber is a commonly used material for manufacturing tires 10.

[0020] Please see Figure 1-3 The inflation mechanism 7 includes an inflation tube 71. The inflation tube 71 is fixedly connected inside the rubber tube 41. The inflation tube 71 is fixedly connected inside the inflation tube 71. Two symmetrically distributed sliding pins 73 are slidably connected inside the support bar 72. A sealing cap 74 is fixedly connected to one end of the sliding pin 73. A spring 75 is provided on the outside of the sliding pin 73. The sealing cap 74 is slidably connected to the inflation tube 71. An external threaded ring 76 is fixedly connected to the outside of the inflation tube 71. The external threaded ring 76 can be connected to the inflation tube of the air pump through threads. The sealing cap 74 can seal the inflation tube 71. One end of the spring 75 is fixedly connected to the support bar 72. The other end of the spring 75 is fixedly connected to the sliding pin 73. The external threaded ring 76 is fixedly connected to the rubber tube 41. The spring 75 can support the sliding pin 73 through elastic force.

[0021] The specific implementation process of this utility model is as follows: When in use, the transition layer 2 acts to bond the gas barrier layer 1 and the carcass layer 3, reduce air bubbles between the carcass layer 3 and the dynamic vulcanized alloy film during production, reduce defects, improve the durability of the finished product, and prevent the carcass layer 3 from delaminating from the dynamic vulcanized alloy film.

[0022] When tire 10 needs to be disassembled, push the sliding pin 73. The sliding pin 73 moves the sealing cover 74 and compresses the spring 75. When the sealing cover 74 is disengaged from the inflation tube 71, the limitation on the inflation tube 71 can be released, thereby allowing the airflow inside the rubber tube 41 to be discharged. This makes the rubber tube 41 and the wire mesh sleeve 42 more flexible, making tire 10 easier to disassemble. After disassembly, gas is injected into the rubber tube 41. After the rubber tube 41 expands, the steel mesh ring 4 formed by the combination of the rubber tube 41 and the wire mesh sleeve 42 becomes rigid under the limiting action of the steel mesh sleeve 42, thus supporting the tire 10.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
