AI Technical Summary
When the existing guide wheel rim is squeezed, it is easy to cause gaps between the tire edge and the rim rim rim, resulting in gas leakage and frequent injection.
A high-sealing guide wheel rim is designed, and by providing a sealing structure at the rim, including a locking groove formed by extending around and bending inwardly from the edge of the rim, and a sealing groove arranged along the slot, ensuring that the tire edge is closely matched and sealed with the ring rim rim.
The high sealing of the guide wheel is achieved, which reduces the possibility of gas leakage, extends the tire's gas volume holding time, and reduces the frequency of pumping.

Abstract
Description
Technical Field
[0001] The utility model relates to, in particular to a guide wheel steel ring with high sealing performance. Background Art
[0002] At present, in some transportation scenarios, goods are generally transported with the help of carts and trailers. For some heavy equipment, they also have their own wheel sets for easy movement. The wheels on general carts or heavy equipment with integrated wheel sets are generally guide wheels or steering wheels. In order to have a certain shock absorption effect, the guide wheels of heavy equipment usually include steel rims and tires arranged on the steel rims. After inflation, the edge of the tire is pressed against the rim of the steel rim due to the effect of the air pressure in the tire to achieve sealing. However, such a structure is prone to cause a gap between the edge of the tire and the rim of the steel rim when the guide wheel is squeezed, resulting in air leakage. Therefore, after a period of use, the air volume of the tire will be greatly reduced, and frequent inflation is required. Utility Model Content

[0014] 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.
[0015] At present, in some transportation scenarios, goods are generally transported with the help of carts and trailers. For some heavy equipment, they also have their own wheel sets for easy movement. The wheels on general carts or heavy equipment with integrated wheel sets are generally guide wheels or steering wheels. In order to have a certain shock absorption effect, the guide wheels of heavy equipment usually include steel rims and tires arranged on the steel rims. After inflation, the edge of the tire is pressed against the rim 2 of the steel rim due to the action of the air pressure in the tire to achieve sealing. However, such a structure is prone to cause a gap between the edge of the tire and the rim 2 of the steel rim when the guide wheel is squeezed, resulting in air leakage. Therefore, after a period of use, the air volume of the tire will be greatly reduced, and frequent inflation is required. For this reason, we propose the following technical solutions:
[0016] A guide wheel steel ring with high sealing performance comprises a base body 1 arranged in a circle, wheel rims 2 are arranged at both ends of the base body 1, a sealing structure is arranged at the wheel rim 2, the sealing structure comprises a groove 6 formed by extending the edge of the wheel rim 2 in all directions and then bending and extending inward, and sealing grooves 7 arranged in a circle along the groove 6 are arranged on the inner walls on both sides of the groove 6.
[0017] The edge of the tire is designed to match the rim 2 of the steel rim. When installing the tire, the edge of the tire is inserted into the slot 6, and the corresponding part of the tire is inserted into the sealing slot 7. After being inflated, a highly sealed structure is formed, which makes the tire less likely to leak.
[0018] According to a preferred technical solution, the rim 2 includes a first connection portion 3 formed by bending and extending the end of the base 1 in a direction away from the central axis of the base 1, the edge of the first connection portion 3 is bent and extended toward the outer end to form a second connection portion 4, the edge of the second connection portion 4 is tilted toward the outer end to form a third connection portion 5, and the slot 6 is formed between the edge of the third connection portion 5 and the second connection portion 4 after being bent inward.
[0019] According to a preferred technical solution, the connection between the first connection part 3 and the base body 1 is arranged in an arc transition, the connection between the second connection part 4 and the first connection part 3 is arranged in an arc transition, and the connection between the third connection part 5 and the second connection part 4 is arranged in an arc transition.
[0020] According to a preferred technical solution, a chrome-plated layer is provided on the surface of the steel ring.
[0021] According to a preferred technical solution, the surface of the steel ring is sprayed with a sandblasting layer, and the surface roughness of the steel ring is increased by sandblasting, so that when the decorative paint is sprayed on, the decorative paint can adhere firmly and is not easy to fall off.
