Technical Field

[0001] The utility model relates to the technical field of tires, in particular to a high-load-bearing solid tire. Background Art

[0002] Solid tires are a type of tire that corresponds to pneumatic tires. Their carcass is solid, without cords as a skeleton, and does not need to be inflated, so no inner tube or airtight layer is required. The earliest tire was a solid tire.

[0003] Existing solid tires are used on vehicles that carry a lot of cargo. When the vehicle is driving, the tires are in contact with the ground. Due to the weight of the vehicle and cargo, and the small tire load-bearing capacity, the tires are very easy to deform, which is very dangerous to drive. In order to improve it, a high-load-bearing solid tire is proposed. Summary of the invention

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4A high-load-bearing solid tire comprises a tire body 1, a wheel hub 2 and a supporting member 3. The wheel hub 2 and the supporting member 3 are both provided with a mounting groove 4, a mounting frame 5 is provided in the mounting groove 4, an extrusion groove 6 is provided on the mounting frame 5, a limiting rod 7 is provided in the extrusion groove 6 through an extrusion mechanism, a limiting hole connected with the mounting groove 4 and corresponding to the limiting rod 7 is provided on the wheel hub 2 and the supporting member 3, a pressing hole 8 corresponding to the limiting rod 7 is provided on the mounting frame 5, a bearing block 10 and a bearing column 11 are respectively installed on the two corresponding mounting frames 5 through a positioning mechanism, a compression groove is provided on the bearing block 10, the bearing column 11 extends into the compression groove, and a buffer mechanism for buffering is provided in the compression groove.

[0022] The extrusion mechanism includes an extrusion spring 16 installed in the extrusion groove 6, and the two ends of the extrusion spring 16 are elastically connected to the outer wall of the limiting rod 7 and the inner wall of the extrusion groove 6 respectively. The extrusion spring 16 realizes the extrusion operation of the limiting rod 7, and can be squeezed into the positioning hole. With the help of the pressing hole 8, the limiting rod 7 in the positioning hole can be squeezed out and returned to the extrusion groove 6, thereby releasing the fixed connection of the mounting frame 5 relative to the mounting groove 4.

[0023] The positioning mechanism includes a positioning rod 12 installed on the supporting block 10 and the supporting column 11, a connecting groove 9 is provided on the mounting frame 5, and a positioning groove 15 is provided on the inner wall of the connecting groove 9. With the help of the positioning rod 12 and the positioning groove 15, the supporting block 10 and the supporting column 11 are positioned and installed with the mounting frame 5.

[0024] The buffer mechanism includes two movable plates 13 installed in the compression groove, and a compression spring 14 is elastically connected between the two movable plates 13. When the weight of the vehicle is transmitted to the tire body 1 during vehicle driving, the wheel hub 2 squeezes the bearing column 11 and other components inward, and the bearing column 11 is elastically hindered from descending by the compression spring 14, thereby alleviating the gravity of the bearing column 11 being squeezed.

[0025] The vertical cross-sectional view of the mounting groove 4 is T-shaped, and the vertical cross-sectional view of the mounting frame 5 is H-shaped. The above-mentioned status quo can be processed and formed by relying on existing technical equipment. After the components of the above-mentioned status quo are connected, they have a limiting operation in a certain direction, and the mounting frame 5 can only move horizontally to complete the connection with the mounting groove 4.

[0026] The cross-sectional views of the compression groove and the movable plate 13 are both square, and the outer wall of the movable plate 13 and the inner wall of the compression groove are both polished. The square structure ensures that the movable plate 13 cannot rotate in the compression groove, and the polishing process ensures smoothness, which facilitates the removal and replacement of the movable plate 13 and the compression spring 14 from the compression groove.

[0027] When the utility model is used, during the driving process of the vehicle, when the weight of the vehicle is transmitted to the tire body 1, the wheel hub 2 presses the bearing column 11 and other components inwardly, and the bearing column 11 is hindered from descending by the elasticity of the compression spring 14, thereby alleviating the gravity of the bearing column 11 being squeezed.

[0028] After the elastic potential energy of the compression spring 14 decays, it needs to be replaced. The replacement steps are as follows: insert a finger or a pressing rod-like component into the pressing hole 8, and then squeeze the limit rod 7 to compress the compression spring 16 and disengage it from the positioning hole, and then release the fixed installation of the mounting frame 5 in the mounting groove 4, and move the mounting frame 5 horizontally to disengage it from the mounting groove 4, thereby driving the supporting block 10 and the supporting column 11 and other components to disengage from the mounting groove 4. After the mounting frame 5 is disassembled, it is easy to disengage from the supporting block 10 and the supporting column 11. In the disengaged state, the movable plate 13 in the compression groove together with the compression spring 14 can be shaken off, the movable plate 13 and the compression spring 14 can be replaced, and the above components can be reinstalled.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
