Description

Technical Field

[0001] The utility model relates to the technical field of off-road tire processing, in particular to a fixing frame for off-road tire processing. Background Art

[0002] Off-road tires are designed for driving in the wild. Different from urban tires and sports tires, they are mainly divided into three types: road tires, all-terrain tires and mud tires. Each has its specific application scenarios and advantages. The off-road tire processing fixture is a device used to fix off-road tires for processing. The design of the fixture should take into account the particularity and processing requirements of off-road tires to ensure the stability and safety of the tires during processing.

[0003] Common tire processing fixing frames are generally limited on the left and right sides by clamping plates when in use, such as announcement CN 213290018 U, a fixing frame for automobile tire processing, including an operating table, an adjustment mechanism and clamping plates to fix the tire.

[0004] However, in this method, when fixing the off-road tire, the clamping plate is used to clamp the off-road tire, which may easily cause the clamping plate to block both sides of the tire, making it inconvenient to process the surface of the tire. In addition, only fixing both sides of the tire with the clamping plate may easily cause the surface of the tire to deform, reducing the accuracy of tire processing and failing to meet the working requirements of tire processing. Therefore, a fixing frame for off-road tire processing is proposed. Utility Model Content
