Abstract
Description
Technical Field
[0001] The utility model relates to the technical field, in particular to a vehicle tire expander. Background Art
[0002] Tires are an important part of vehicles. They directly affect the safety of vehicle driving and braking, so they need to be maintained regularly. When repairing or replacing vehicle tires, the traditional method is to use a crowbar to pry open the tire bead, and then repair the inner tube and cushioning strip. Because the force of manually moving the crowbar is limited, this operation method is only suitable for small-sized tires. At the same time, inserting the crowbar into the tire bead will also limit the actual operating space, which brings a lot of inconvenience to repair and replacement.
[0003] Scheme CN203126417U discloses a tire bead expander, including a bracket, a tire bead lower hook is provided at the lower part of the bracket, a pressure lever is connected to the upper part of the bracket, and a tire bead upper hook is provided on the pressure lever. When in use, the tire bead lower hook and the tire bead upper hook are hooked on both sides of the tire bead respectively, and the tire bead can be expanded by pressing down the pressure lever. The operation is simple and labor-saving. In addition, there is no tool to block the tire expansion part, which brings a lot of convenience to maintenance and replacement. However, this scheme requires the tire bead lower hook to be hooked on the tire bead, which requires lifting the tire first and then inserting the tire bead lower hook from the bottom into the tire bead. In reality, truck tire maintenance and replacement are very common, and most truck tires are large in size and very heavy, which is difficult for one person to lift. Therefore, when this scheme is applied to large tires, it is laborious, difficult, and inconvenient to operate. Utility Model Content
