Description

Technical Field

[0001] The utility model relates to the technical field of puncture-proof tires, in particular to a puncture-proof wheel tire. Background Art

[0002] Tires are circular, elastic rubber products that roll onto the ground and are typically mounted on metal rims. They support the vehicle's body, cushion external impacts, maintain contact with the road, and ensure vehicle performance. Tires are often used in complex and demanding conditions, enduring various deformations, loads, forces, and high and low temperatures during driving.

[0003] In the prior art, except for some special tires that can withstand punctures from harder objects and metals, ordinary tires are generally made mainly of rubber, and the rubber texture of the outer tire is relatively hard. In order to increase its strength during driving, a filling layer is set inside the outer tire, and the main part of the filling layer is elastic filling composed of elastic material, which is used to increase the toughness of the tire and improve the driving comfort of the vehicle. However, a certain amount of heat will be generated under long-term use, which will easily soften the outer tire. At this time, when the tire passes over a poor road surface, it is easy for the outer tire to be penetrated by sharp stones and other debris, and then it is easy for the inner tube to be punctured after the foreign object penetrates the tire, affecting the driver's driving. At the same time, it is generally not easy to observe the foreign object in time after the tire is punctured, so it is easy for the driver to drive after the outer tire is damaged without discovering it in time, which can easily affect driving safety. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a puncture-resistant wheel tyre to solve the technical problems mentioned in the above background technology.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A puncture-proof wheel tire comprises an outer carcass, an inner connecting ring fixedly connected therein, a gap being left between the outer peripheral side of the inner connecting ring and the circumferential side wall inside the outer carcass to form a cavity, positioning rings being fixedly connected to both side walls in the cavity, a counterweight baffle being slidably connected between the two positioning rings, and a gap being left between the bottom side of the counterweight baffle and the circumferential side wall inside the outer carcass.

[0007] In a preferred example, the present invention can be further configured as follows: water is injected into the cavity, and the liquid level of the water in the cavity is higher than the counterweight baffle.

[0008] In a preferred example, the present invention can be further configured as follows: a first steel mesh ring is fixedly embedded in the circumferential side wall of the outer carcass, and a second steel mesh ring is fixedly embedded in the outer circumferential side of the inner connecting ring.

[0009] In a preferred example, the present invention can be further configured as follows: both side walls of the cavity are fixedly connected to supporting rubber plates, and a number of elastic rings are embedded in the supporting rubber plates.

[0010] In a preferred example, the present invention can be further configured as follows: the counterweight baffle is arranged in an arc shape, and the curvature of the counterweight baffle is the same as the curvature of the outer carcass.

[0011] In a preferred example, the present invention can be further configured as follows: an arcuate groove is provided on the side wall of the counterweight baffle, and the counterweight baffle is slidably connected to the positioning ring through the arcuate groove.

[0012] In summary, the present invention has at least one of the following beneficial technical effects:

[0013] 1. This puncture-resistant wheel tire can always face the ground with the bottom side of the weighted baffle during use, blocking foreign objects on bumpy roads, thereby preventing sharp foreign objects from piercing the outer carcass and damaging the inner tube. At the same time, a certain amount of water can be injected. If the outer carcass is pierced by a sharp object, the water will flow out through the hole, making it easier for the driver to observe whether the tire is damaged, thereby improving driving safety.

[0014] 2. This puncture-resistant wheel tire has a cooling effect due to the water injected into the cavity. The circumferential sidewalls of the cavity are smooth and therefore less affected by rotation, preventing the water from rotating with the tire carcass. Furthermore, the resistance of the water further stabilizes the counterweight baffle, preventing it from rotating due to the rotation of the wheel. Furthermore, if a foreign object is inserted into the tire carcass, the water will flow outward through the hole where the foreign object was inserted, making it easier for the driver to inspect the tire for damage.

[0015] 3. This puncture-resistant wheel cover has a support rubber plate and an elastic ring to protect the sidewalls within the cavity, thereby improving the support stability of the sidewalls. The elastic ring is made of steel wire and, after being embedded in the support rubber plate, improves the rigidity and stability of the support rubber plate.

[0016] 4. In this puncture-proof wheel tire, the edges of the top and bottom side walls of the arc-shaped groove are in contact with and slidably connected to the positioning ring, and a certain gap is left between the inner side walls of the arc-shaped groove and the positioning ring, thereby reducing the friction between the counterweight baffle and the positioning ring, reducing the shaking caused by the rotation of the outer tire body, and at the same time, water can enter this part of the gap, thereby further reducing friction and improving stability.

[0024] The present invention will be described in further detail below with reference to the accompanying drawings.

[0025] Example:

[0026] Reference Figure 1-Figure 5 The utility model discloses a puncture-proof wheel tire, including an outer carcass 1, an inner connecting ring 2 is fixedly connected to the outer carcass 1, a gap is left between the outer peripheral side of the inner connecting ring 2 and the peripheral side wall inside the outer carcass 1 to form a cavity 3, and two side walls in the cavity 3 are fixedly connected to positioning rings 4, and a counterweight baffle 5 is slidably connected between the two positioning rings 4, and a gap is left between the bottom side of the counterweight baffle 5 and the peripheral side wall inside the outer carcass 1.

[0027] In this embodiment, when the vehicle is traveling, the outer carcass 1 will rotate, and the vehicle generally travels at a slow speed on bumpy roads. At this time, although the outer carcass 1 is rotating, due to the weight of the counterweight baffle 5, and the fact that the counterweight baffle 5 is slidably connected to the positioning ring 4, gravity will cause the counterweight baffle 5 to always be located below the cavity 3, and the bottom side of the counterweight baffle 5 will always face the ground. After a sharp foreign object is inserted into the outer carcass, the counterweight baffle 5 will block the sharp foreign object, preventing the sharp foreign object from piercing the outer carcass 1 and damaging the inner tube, thereby causing tire leakage and affecting vehicle driving.

[0028] In a further preferred embodiment of the present invention, Figure 1-5 As shown, water is injected into the cavity 3 , and the liquid level of the water in the cavity 3 is higher than the counterweight baffle 5 .

[0029] In this embodiment, the water injected into the cavity 3 can play a cooling role, and the peripheral side walls in the cavity 3 are smooth and therefore less affected by the rotation, thereby preventing the water from rotating with the rotation of the outer carcass 1. In addition, the resistance of the water further stabilizes the counterweight baffle 5, preventing the counterweight baffle 5 from rotating due to the rotation of the wheel. At the same time, if the outer carcass 1 is pierced by a foreign object, the water will flow outward along the hole where the foreign object is inserted, thereby making it convenient for the driver to observe whether the tire is damaged.

[0030] In a further preferred embodiment of the present invention, Figure 2-3 As shown, a first steel mesh ring 6 is fixedly embedded in the circumferential side wall of the outer carcass 1 , and a second steel mesh ring 7 is fixedly embedded in the outer circumferential side of the inner connecting ring 2 .

[0031] In this embodiment, the first steel mesh ring 6 and the second steel mesh ring 7 are provided to provide a certain support force for the outer carcass 1, reducing the degree of deformation in the cavity 3, thereby causing the counterweight baffle to shake violently, affecting the protection of the outer carcass 1.

[0032] In a further preferred embodiment of the present invention, Figure 2 As shown, both side walls of the cavity 3 are fixedly connected with supporting rubber plates 8 , and a number of elastic rings 9 are embedded in the supporting rubber plates 8 .

[0033] In this embodiment, the supporting rubber plate 8 and the elastic ring 9 are provided to protect the side walls inside the cavity 3, thereby improving the support stability of the side walls of the cavity 3. The elastic ring 9 is made of steel wire, and after being embedded in the supporting rubber plate, the rigidity and stability of the supporting rubber plate are improved.

[0034] In a further preferred embodiment of the present invention, Figure 4As shown, the counterweight baffle 5 is arranged in an arc shape, and the curvature of the counterweight baffle 5 is the same as the curvature of the outer carcass 1 .

[0035] In this embodiment, the curvature of the counterweight baffle 5 is the same as that of the outer carcass 1, so that the bottom side wall of the counterweight baffle 5 and the peripheral side wall of the cavity 3 form a consistent shielding, avoiding the reduction of the shielding area due to the difference in curvature, thereby affecting the shielding of the outer carcass 1.

[0036] In a further preferred embodiment of the present invention, Figure 5 As shown, an arcuate groove 10 is provided on the side wall of the counterweight baffle 5 , and the counterweight baffle 5 is slidably connected to the positioning ring 4 through the arcuate groove 10 .

[0037] In this embodiment, the edges of the top side wall and the bottom side wall of the arc groove 10 are in contact with and slidingly connected to the positioning ring 4, and a certain gap is left between the inner side wall of the arc groove 10 and the positioning ring 4, thereby reducing the friction between the counterweight baffle 5 and the positioning ring 4, and reducing the shaking caused by the rotation of the outer carcass 1. At the same time, water can also enter this part of the gap, thereby further reducing friction and improving stability.

[0038] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
