Description

Technical Field

[0001] The utility model relates to the technical field of automobile maintenance, in particular to a self-locking automobile maintenance lifting structure. Background Art

[0002] During maintenance, it is usually necessary to use a lifting platform to lift a car or other vehicle to a suitable height so as to carry out repair, maintenance and maintenance. There are two existing lifting platforms. One is to drive the car directly to the lifting platform, first limit the tires of the car to prevent the car body from moving, and then directly lift the entire car to a suitable height. The other is to lift the car body on the lifting platform, while the tires are not on the lifting platform, so that the tires can be easily removed.

[0003] However, the first type of lifting platform cannot be used to dismantle the tires of the car. During the second type of maintenance, once the heavier parts of the car are removed, the center of gravity of the car will change, and the center of gravity of the car on the lifting platform will be unevenly distributed, which will cause the entire car body to roll over and cause harm to the workers.

[0004] Based on this, the utility model designs a self-locking automobile maintenance lifting structure to solve the above problems. Utility Model Content
