Technical Field
The invention relates to a bulletproof tire structure, and belongs to the technical field of safety tires.
Background
The prior bulletproof tire is basically characterized in that other supports such as a bulletproof support body or a bulletproof inner tube and the like are arranged in the pneumatic tire, and after a bullet in the tire is punctured or the tire is burst in driving and punctured and leaks, the other supports (hereinafter collectively referred to as the support body) such as the bulletproof support body or the bulletproof inner tube and the like in the tire can replace the pneumatic tire to play a role in supporting the weight of a vehicle body and ensure that the tire does not slip, thereby achieving the aim of enabling the vehicle to continue driving. The situation that the supporting body in the existing bulletproof tire slides left and right along the binding surface of the rim in the actual use process can cause the dynamic balance of the safety tire to be poor and the controllability to be reduced during high-speed running.
In order to ensure that the supporting body cannot slide left and right in the using process, the conventional method is to hoop the supporting body on the rim by adopting a mode of increasing pretightening force. Alternating force and alternating acceleration that the actual vehicle driving process produced, vehicle vibration that the road surface is uneven leads to, the expend with heat and contract with cold that ambient temperature change leads to all can lead to supporter inner circle material because of sliding distance is big, and friction heating up and ageing, the tension reduces, and the supporter still can be along rim binding face horizontal slip, can not get back to the rim center automatically. Therefore, the prior art still has the defects and needs to be further improved.
Disclosure of Invention

In order to achieve the purpose, the invention adopts the following technical scheme:
a bulletproof tire structure of the present invention includes a tire; one or more centering and positioning nails are arranged on both sides of the support body in the tire; the support body is contacted with the inner edge of the bottom of the tire on the inner side of the rim through the centering and positioning nails on the two sides so as to keep the support body always positioned on the center line of the rim.
In the bulletproof tire structure, the centering positioning nail is a component made of elastic flexible materials or a compression deformation elastic component which can recover to an initial state after external force is released.
In the bulletproof tire structure, the centering positioning nail is of a columnar structure or a sheet structure; the columnar structure is cylindrical or polygonal columnar; the interior of the columnar structure or the sheet structure is a hollow structure or a solid structure.
In the bulletproof tire structure, the support body is an annular structure formed by splicing one or more fan-shaped support units through bolts at a Z-shaped interface; the section of the fan-shaped supporting unit is in an I-shaped steel rail shape, one or more positioning holes are formed in two sides of a lower wing plate of the I-shaped steel rail, and centering positioning nails are installed in the positioning holes.
In the bulletproof tire structure, the Z-shaped interface is formed by butting connecting notches arranged on different side surfaces of two ends of the fan-shaped supporting unit; the connecting notch is provided with a bolt hole.
The tire is an inflatable tire.
Due to the adoption of the technical scheme, compared with the prior art, the invention adopts the technology of additionally arranging the centering positioning nail on the side surface of the support body. The centering and positioning nails are arranged on the side surface of the support body, so that the assembly of the bulletproof tire is not influenced, in the inflation use process, the centering and positioning nails absorb pressure and vibration generated in the left-right sliding process of the support body, the left-right automatic centering of the support body is realized, and the support body is always positioned in the center of the rim. The invention has the characteristics of simple structure, convenient installation, good dynamic balance performance and the like, can be used for vehicles with the requirements of bulletproof performance and air leakage prevention, and has better effect.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
A bulletproof tire structure of the present invention, as shown in fig. 1 and 2, includes a tire 1; the tire 1 is a pneumatic tire, and one or more centering pins 3 are arranged on two sides of a support body 2 in the tire 1; the support body 2 is contacted with the inner edge 5 of the bottom of the tire on the inner side of the rim 4 through the centering nails 3 on two sides so as to keep the support body 2 always positioned on the center line 6 of the rim. The centering and positioning nail 3 is made of elastic flexible material or is a compression deformation elastic component, and can be restored to the initial state after external force is released. The centering and positioning nail 3 is of a columnar structure or a sheet structure; the interior of the columnar structure or the sheet structure is a hollow structure or a solid structure; the section of the columnar structure is circular or polygonal.
The supporting body 2 is formed by splicing one or more fan-shaped supporting units 7 shown in FIG. 4 into a ring-shaped structure shown in FIG. 3 through bolts 9 at Z-shaped interfaces 8; the section of the fan-shaped supporting unit 7 is in an I-shaped steel rail shape, one or more positioning holes 10 are formed in two sides of a lower wing plate of the I-shaped steel rail, and centering positioning nails 3 are installed in the positioning holes 10; the Z-shaped interface 8 is formed by butting connecting notches 11 arranged on different side surfaces of two ends of the fan-shaped supporting unit 7; the connecting gap 11 is provided with a bolt hole 12.
