Description

Technical Field

[0001] The present invention relates to the technical field of tires, in particular to an injection-type solid rubber tire. Background Art

[0002] A tire is a circular, elastic rubber product that rolls against the ground and is mounted on various vehicles or machinery. Pneumatic tires are a type of tire. Early pneumatic tires used rubber-coated canvas as the tire body. Tires are often used in complex and harsh conditions, enduring various deformations, loads, forces, and high and low temperature conditions during driving. Therefore, tires must have high load-bearing capacity, traction performance, and cushioning properties. They also require high wear resistance and flex resistance, as well as low rolling resistance and heat buildup. In existing technologies, some rubber tires are first formed by injecting the rubber tire raw material into a mold and cooling it, and then welding the rubber tire to the rim.

[0003] For example, Chinese patent publication number CN204870381U discloses a utility model providing a combined rubber solid wheel comprising a rim, a rubber layer, and a hard rubber core arranged sequentially from the outside to the inside of the rim. An annular protrusion is provided on each side of the rim ring, and at least two rows of hook-shaped protrusions are provided on the outer surface of the rim ring. The hard rubber core has a circular cross-section and includes an annular deformation gap within the hard rubber core. The deformation gap gradually expands from the opening toward the inside. The rubber layer is wrapped around the outside of the hard rubber core and compresses the deformation gap to form a tread. The addition of the hook-shaped protrusions to the tire effectively prevents lateral slippage and prevents the tire from falling off the rim. The deformation gap designed into the core also allows for timely release of heat within the tire, while also improving its overall elastic performance.

[0004] However, the above device still has the following shortcomings: since the tires are often driven on various complex surfaces, the tires are severely worn after long-term use and need to be disassembled for replacement, but it is troublesome to remove the solid rubber wheel from the rim, and the tire will be damaged by vibration when encountering bumpy ground during driving, thereby reducing the service life of the rim. Summary of the Invention

[0008] A further improvement of the technical solution of the present invention is that the annular strip is fixedly mounted on one side outer wall of the annular seat, and nuts are fixed on both side outer walls of the solid rubber inner tube.

[0010] A further improvement of the technical solution of the present invention is that a receiving ring is fixedly installed on the bottom of the metal connecting plate, and an annular groove is opened on the inner wall of the receiving ring, and the annular groove is adapted to the annular strip.

[0011] A further improvement of the technical solution of the present invention is that a rubber damping block is fixedly mounted on the inner wall of the protection groove, and a rebound frame is fixedly mounted on the outer wall of the rubber damping block.

[0012] A further improvement of the technical solution of the present invention is that: a pinball is fixedly mounted on the inner wall of the rebound frame, the rebound frame is made of foam, and the pinball is made of propylene-based elastomer.

[0013] A further improvement of the technical solution of the present invention is that a connecting column is fixedly installed on one side outer wall of the rebound frame, and the material of the connecting column is polyurethane.

[0014] A further improvement of the technical solution of the present invention is that a protective outer tire is fixedly mounted on the outer wall of the solid rubber inner tire, a rubber anti-skid block is fixedly mounted on the outer wall of the protective outer tire, and an anti-skid groove is opened on the outer wall of the protective outer tire.

[0015] Due to the adoption of the above technical solution, the present invention has the following technical advancements compared to the prior art:

[0016] 1. The present invention provides an injection-type solid rubber tire. The solid rubber inner tube is obtained by injecting rubber tire raw materials into a mold and cooling and molding the tire under the interaction of a solid rubber inner tube, a connecting mechanism, an annular seat, a metal connecting plate, an annular strip, a nut, a screw, and an annular groove. At this time, the solid rubber inner tube is sleeved on the outer side of the rim, and then the metal connecting plate is moved to align the screw with the nut. At the same time, the annular groove on the upper receiving ring is clamped on the annular strip. Then, the screw is turned to fix the metal connecting plate on the solid rubber inner tube. The metal connecting plate fixes the rim, thereby connecting the rim and the solid rubber inner tube. The tire has the advantage of convenient assembly and disassembly.

[0017] 2. The present invention provides an injection-type solid rubber tire. Through the interaction of the stainless steel ring, the protective groove, the rubber damping block, the bouncing ball, the rebound frame, and the connecting column, when the tire encounters bumps on an uneven ground, the rubber solid inner tube itself can buffer the vibration. At the same time, when the rubber solid inner tube encounters bumps, it will squeeze the rubber damping block, the rubber damping block will squeeze the rebound frame, and the rebound frame will squeeze the bouncing ball and the connecting column. The materials of the rebound frame, the bouncing ball, and the connecting column are all elastic, and when subjected to vibration, they can cooperate with the rubber damping block to buffer the vibration, thereby protecting the rim inside the stainless steel ring, increasing the service life of the rim, and having the advantage of convenient protection of the rim.

[0018] 3. The present invention provides an injection-type solid rubber tire. Through the interaction of the protective outer tire, rubber anti-skid blocks, and anti-skid grooves, the protective outer tire can reduce the friction between the rubber solid inner tire and the ground, thereby increasing the service life of the tire. The rubber anti-skid blocks can increase the contact area between the protective outer tire and the ground, making the tire less likely to slip. Moreover, the obliquely arranged anti-skid grooves can further increase the friction force, thereby increasing the driving safety of the vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

The rubber anti-skid blocks 48 arranged on the protective outer tire 47 can protect the outer tire 47 from increasing the contact area with the ground, making the tire less likely to slip. Moreover, the anti-skid grooves 49 arranged obliquely can further increase the friction between the protective outer tire 47 and the ground, thereby increasing the driving safety of the vehicle.

[0036] The working principle of the injection type solid rubber tire is described in detail below.

The service life of the rim 1 is increased, and it has the advantage of conveniently protecting the rim 1. The protective outer tire 47 arranged on the outside of the rubber solid inner tube 2 can reduce the friction between the rubber solid inner tube 2 and the ground, thereby increasing the service life of the rubber solid inner tube 2. The rubber anti-skid blocks 48 arranged on the protective outer tire 47 can protect the outer tire 47 from increasing the contact area with the ground, making the tire less likely to slip, and the anti-skid grooves 49 arranged obliquely can further increase the friction between the protective outer tire 47 and the ground, thereby increasing the safety of automobile driving.

[0038] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made based on the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
