Technical Field

[0001] This utility model relates to the field of run-flat tire technology, specifically a run-flat tire. Background Technology

[0002] With the rapid development of the motorcycle and electric bicycle industry, the number of motorcycles and electric bicycles used for transportation in my country is increasing day by day. Improving tire performance and developing safe, durable and convenient tires is now imperative. Traditional tires use nylon cord as the tire carcass material, which is easily punctured during use. Once punctured, riders must push their bikes to a repair shop, which is time-consuming and laborious.

[0003] Existing run-flat tires can only be driven slowly when they burst and have zero air pressure, and the range is only a few kilometers, which greatly reduces the tire's efficiency. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, this utility model provides a run-flat tire, which solves the problem that existing run-flat tires can only be driven slowly when a blowout occurs and the air pressure is 0, and the driving distance is only a few kilometers, which greatly reduces the tire's usage efficiency.

[0006] (II) Technical Solution

[0007] To achieve the above, this utility model provides the following technical solution: a run-flat tire, comprising a body and wheel teeth:

[0008] The main body has a through mounting opening on its front side, and a reinforcing rod is provided inside the main body;

[0009] The gear teeth have a fixing plate inside, and fixing rods are provided on both the upper and lower surfaces of the fixing plate. A connecting plate is provided on the top of each fixing rod.

[0010] The gear teeth are arranged around the outer wall of the main body, and the main body and the gear teeth are combined into a whole, which can effectively support the main body and prevent the main body from sinking.

[0011] Optionally, two reinforcing rods are provided, and reinforcing teeth are arranged laterally at equal intervals on the inner side of both reinforcing rods. The cross-section of the reinforcing teeth is triangular. The reinforcing teeth interlock, which can effectively achieve the supporting effect of the main body and the protective effect of the main body, and at the same time effectively increase the puncture resistance of the main body.

[0012] Optionally, a steel strip is provided directly below the reinforcing rod. The steel strip is made of steel wire cord twisted together with a certain degree of twist, which can further enhance the puncture resistance of the main body and increase its puncture resistance.

[0013] Optionally, the main body is provided with a top column inside, and a top rod is embedded inside the top column. The outer ends of the two top rods are respectively in contact with two steel strips. A buffer spring is provided inside the top column. One end of the two top rods embedded in the top column is connected to the upper and lower ends of the buffer spring. This can effectively achieve the supporting effect of the main body while also achieving the buffering effect of the main body, further preventing the main body from denting.

[0014] Optionally, the outer surface of the gear teeth is provided with a wear-resistant layer, which may be made of polyurethane and butadiene rubber. Reinforcing ribs are provided below the wear-resistant layer to effectively increase the wear resistance of the gear teeth.

[0015] Optionally, the reinforcing rib is provided in two parts. The lower surface of the reinforcing rib has support blocks arranged at equal intervals in a convex shape. The upper surface of the other reinforcing rib has support blocks arranged at equal intervals in a convex shape. The support blocks engage with each other, which can effectively strengthen the interior of the main body and prevent the interior of the main body from sinking.

[0016] Optionally, the top of the connecting plate is provided with a buffer, the top of which contacts the bottom of the reinforcing rib, which can effectively achieve a buffering effect on the interior of the main body.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a run-flat tire with the following advantages:

[0019] 1. This utility model uses reinforcing rods, reinforcing teeth, steel belts, and top columns. When the main body is in motion, the two reinforcing rods interlock with each other. The longer the motion, the stronger the interlocking between the two reinforcing rods becomes, thereby achieving the effect of supporting the internal structure of the main body and preventing it from cracking. The steel belt can effectively improve the flexibility of the main body and enhance its comfort.

[0020] 2. This utility model uses a top rod and a buffer spring. During the driving process, the top rod supports the interior of the main body, while the buffer spring buffers the two top rods, thereby reducing the pressure on the main body during driving and further achieving the effect of preventing the main body from bursting.

[0021] 3. This utility model uses reinforcing ribs, a buffer, support block one, and support block two. During the driving process, the support blocks one and support block two of the two reinforcing ribs mesh with each other. When they mesh, they can effectively increase the tensile strength of the wheel teeth and increase the service life of the wheel teeth. When the main body drives the wheel teeth, the buffer can effectively achieve the buffering effect on the wheel teeth and avoid the phenomenon of wheel teeth breaking. Attached Figure Description

[0029] 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.

[0030] Example: Please refer to Figures 1 to 5 The present invention provides a technical solution: a run-flat tire, comprising a main body 1 and wheel teeth 2.

[0031] The main body 1 has an installation port 101 through the front, and a reinforcing rod 102 is provided inside the main body 1.

[0032] Gear 2, the inside of gear 2 is provided with a fixing plate 201, the upper and lower surfaces of the fixing plate 201 are provided with fixing rods 204, and the top of the fixing rods 204 is provided with a connecting plate 205;

[0033] The gear teeth 2 are arranged around the outer wall of the main body 1. The main body 1 and the gear teeth 2 are combined into a whole. When the main body 1 is in motion, the reinforcing rod 102 can strengthen the internal support of the main body 1 and prevent the main body 1 from denting. At the same time, the reinforcing rod 102 can effectively prevent the main body 1 from cracking.

[0034] Based on the above embodiments, this embodiment provides two reinforcing rods 102. The inner sides of the two reinforcing rods 102 are provided with reinforcing teeth 105 arranged horizontally at equal intervals. The cross-section of the reinforcing teeth 105 is triangular. The reinforcing teeth 105 mesh with each other. When the main body 1 is in motion, the two reinforcing rods 102 mesh with each other. The longer the driving process, the stronger the meshing between the two reinforcing rods 102 becomes, thereby achieving the effect of supporting the interior of the main body 1 and preventing the main body 1 from bursting.

[0035] Based on the above embodiments, in this embodiment, a steel strip 103 is provided directly below the reinforcing rod 102. The steel strip 103 is made of steel wire cord twisted together with a certain twist. The steel strip 103 can effectively improve the flexural resistance of the main body 1 and improve the comfort of the main body 1.

[0036] Based on the above embodiments, in this embodiment, the main body 1 is provided with a top column 104 inside, and a top rod 106 is embedded inside the top column 104. The outer ends of the two top rods 106 are respectively in contact with two steel strips 103. The top column 104 is provided with a buffer spring 107 inside, and one end of the two top rods 106 embedded in the top column 104 is connected to the upper and lower ends of the buffer spring 107. When the main body 1 is in motion, the top rods 106 support the interior of the main body 1, and the buffer springs 107 buffer the two top rods 106, thereby buffering the pressure on the main body 1 during the motion, thereby further achieving the anti-explosion effect of the main body 1.

[0037] Based on the above embodiments, in this embodiment, the outer surface of the gear tooth 2 is provided with a wear-resistant layer 202. The wear-resistant layer 202 can be made of polyurethane and butadiene rubber. A reinforcing rib 203 is provided below the wear-resistant layer 202. When the main body 1 is in motion, the wear amount of polyurethane is only 30-80 mm³, which is 3-5 times that of ordinary rubber. Its high strength and fatigue resistance can reduce the risk of cracks and fractures, and significantly extend the service life. At the same time, the wear amount of butadiene rubber is 80-140 mm³, which can balance wear resistance and tear resistance, thereby further achieving a wear-resistant effect on the main body 1 and preventing the main body 1 from wearing out.

[0038] Based on the above embodiments, this embodiment provides two reinforcing ribs 203. The lower surface of one reinforcing rib 203 has support blocks 207 arranged horizontally at equal intervals, and the support blocks 207 are arranged in a convex shape. The upper surface of the other reinforcing rib 203 has support blocks 208 arranged horizontally at equal intervals, and the support blocks 208 are arranged in a convex shape. The support blocks 207 and the support blocks 208 mesh with each other. During the operation of the main body 1, the support blocks 207 and the support blocks 208 of the two reinforcing ribs 203 mesh with each other. When they mesh, they can effectively increase the tensile strength of the gear teeth 2 and increase the service life of the gear teeth 2.

[0039] Based on the above embodiments, in this embodiment, the top of the connecting plate 205 is provided with a buffer 206. The top of the buffer 206 contacts the bottom of the reinforcing rib 203. When the main body 1 drives the gear 2 to move, the buffer 206 can effectively achieve the buffering effect on the gear 2 and prevent the gear 2 from bursting.
