Description

Technical Field

[0001] The utility model belongs to the field of tires, in particular to a mother-and-child anti-skid tire. Background Art

[0002] Tires are rubber products installed on vehicle wheels for shock absorption, support and traction. They are an important part of vehicle driving and have a significant impact on vehicle performance and safety.

[0003] However, the existing tires are relatively fixed in form. When the tire surface is worn out and damaged due to long-term use and cannot be used, it needs to be replaced as a whole, which has high cost and is inconvenient for personnel to use. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a mother-and-child anti-skid tire to solve the problems mentioned in the above background technology.

[0005] A mother-child anti-skid tire comprises a main body, a mother tire, and a child tire arranged at the periphery of the mother tire; a connecting mechanism arranged between the mother tire and the child tire; and an anti-skid mechanism arranged on the outer surface of the child tire.

[0006] Preferably, the inner diameter of the sub-tire is smaller than the outer diameter of the mother tire.

[0007] Preferably, the connection mechanism comprises a plurality of recessed slots arranged on the outer surface of the mother tire and a plurality of raised blocks arranged on the inner surface of the child tire.

[0008] Preferably, the number of the recessed card slots is the same as the number of the raised card blocks, the depth of the recessed card slots is greater than the height of the raised card blocks, and the recessed card slots and the raised card blocks are both inclined.

[0009] Preferably, the anti-slip mechanism includes a plurality of tire patterns arranged on the outer surface of the sub-tire, tire patterns arranged between the tire patterns, and longitudinal patterns arranged on the outer surface of the tire patterns.

[0010] Preferably, the tire pattern body is a diamond-shaped trapezoidal body, and the tire pattern is a bidirectional herringbone trapezoidal body.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The utility model can stably connect the mother tire and the sub-tire together through the connecting mechanism, increase the diameter of the tire, reduce the energy consumption of the vehicle, and easily connect the mother tire and the sub-tire by inflating and deflating the mother tire. It is easy to disassemble and assemble. When the sub-tire is damaged, only a partial replacement is required instead of a complete replacement, which reduces the use cost and is convenient for personnel to use.

[0013] 2. The utility model can improve the stability of the vehicle when driving on icy and snowy roads through the anti-skid mechanism, reduce skidding, increase ground contact friction, reduce braking distance, and improve vehicle driving stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] As attached Figure 1 To Attachment Figure 3 As shown:

[0024] Embodiment 1: The utility model provides a mother-and-child anti-skid tire, comprising a main body 1, including a mother tire 101, and a child tire 102 arranged on the periphery of the mother tire 101; a connecting mechanism 2, arranged between the mother tire 101 and the child tire 102; and an anti-skid mechanism 3, arranged on the outer surface of the child tire 102, wherein the outer surface of the child tire 102 is provided with two stripes, one side is wide and the other side is narrow, so as to facilitate the staff to distinguish between left and right.

[0025] Specifically, the inner diameter of the sub-tire 102 is smaller than the outer diameter of the mother tire 101, which can ensure that when the sub-tire 102 is installed on the mother tire 101 and the mother tire 101 is fully inflated, the sub-tire 102 will not slip, fall off or be misplaced, thereby improving the connection stability between the mother tire 101 and the sub-tire 102.

[0026] Furthermore, the connection mechanism 2 includes a plurality of recessed slots 202 disposed on the outer surface of the mother tire 101 , and a plurality of raised blocks 201 disposed on the inner surface of the child tire 102 .

[0027] Furthermore, the number of the recessed card grooves 202 and the raised card block 201 is the same, the depth of the recessed card grooves 202 is greater than the height of the raised card block 201, and the recessed card grooves 202 and the raised card block 201 are both inclined, wherein the recessed card grooves 202 and the raised card block 201 are both at a 45-degree angle to the tire plane, thereby increasing the separation resistance after the mother tire 101 and the sub-tire 102 are connected, improving the safety and stability of the device after connection, and facilitating personnel use. By making the depth of the recessed card grooves 202 greater than the height of the raised card block 201, the recessed card grooves 202 will completely wrap the raised card block 201 after the mother tire 101 has sufficient air pressure, further improving the connection stability between the mother tire 101 and the sub-tire 102.

[0028] As can be seen from the above, when in use, the mother tire 101 can be deflated first, and then the sub-tire 102 can be put on the mother tire 101, so that the concave groove 202 is engaged with the convex block 201, and then the mother tire 101 is fully inflated. The mother tire 101 will gradually expand due to the filling of gas to prop up the sub-tire 102, thereby connecting the mother tire 101 and the sub-tire 102 together. By assembling the sub-tire 102 on the mother tire 101, the diameter of the assembled tire is larger than the diameter of the original mother tire 101, thereby reducing the fuel consumption of the vehicle. When it is necessary to disassemble the sub-tire 102, it is only necessary to deflate the mother tire 101. The mother tire 101 will shrink synchronously due to the loss of gas, so that the concave groove 202 automatically disengages from the convex block 201, and the sub-tire 102 can be easily disassembled and removed. The disassembly and assembly are convenient. When the sub-tire 102 is damaged due to long-term driving of the vehicle, it is only necessary to remove the sub-tire 102 and replace it. There is no need to replace the entire tire, which reduces the cost of use and is convenient for personnel to use.

[0029] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the anti-skid mechanism 3 includes a plurality of tire patterns 302 arranged on the outer surface of the sub-tire 102, a tire pattern 301 arranged between the tire patterns 302, and a longitudinal pattern 303 arranged on the outer surface of the tire patterns 302.

[0030] Specifically, the tire pattern 302 is a diamond-shaped trapezoid, and the tire pattern 301 is a bidirectional herringbone trapezoid, wherein the tire pattern 302 is a trapezoid with a small upper bottom surface and a large lower bottom surface, and the tire pattern 301 is a trapezoid with a large upper bottom surface and a small lower bottom surface.

[0031] As can be seen from the above, when a vehicle is traveling on an icy or snowy road, the two-way herringbone trapezoidal tread pattern 301 can allow ice and snow to slide out through the inclined surface of the trapezoidal body when entering the tread pattern 301, thereby preventing ice and snow from completely filling the tread pattern 301 and reducing slippage. The diamond tread body 302 with a longitudinal pattern 303 can increase the contact area between the tire and the ground when the vehicle brakes, increase ground friction, reduce braking distance, and improve vehicle driving safety.

[0032] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
