Description

Technical Field

[0001] The utility model belongs to the technical field of semi-solid tires, in particular to a semi-solid tire which is easy to disassemble and assemble. Background Art

[0002] Semi-solid tires, also known as semi-hollow tires or filled tires, are a type of tire between solid tires and pneumatic tires. The interior is not completely solid, but uses special fillers or structural designs to achieve better shock absorption and comfort than solid tires, while being more resistant to punctures and wear than pneumatic tires. Semi-solid tires need to be installed on the outside of the rim. The rim provides a certain amount of support for the tire and improves the transition connection with the internal rotating mechanism. However, in order to improve the tightness of the connection with the rim, the common semi-solid tire has a structure that makes it inconvenient to disassemble and assemble. It often requires greater strength and the use of additional tools to disassemble and assemble the semi-solid tire, which will cause some problems.

[0003] First, when a tire is damaged, worn, or needs to be replaced, the disassembly and assembly process is too complicated and time-consuming, which will prolong the downtime for maintenance and affect the normal use efficiency of the vehicle or equipment. Difficult disassembly and assembly may require more manpower and increase the labor intensity of maintenance personnel, and may also lead to additional safety risks due to improper operation.

[0004] Secondly, in emergency situations, such as when a tire suddenly breaks or fails, if it is difficult to disassemble and assemble, it will be difficult to quickly carry out a temporary replacement, which may cause greater economic losses or delay the execution of important tasks.

[0005] In summary, the semi-solid tire that is not easy to disassemble and assemble has some problems in use, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
