Existing tire balancing machines typically consist of a balancing machine body and a fixing mechanism mounted on the machine body. The fixing mechanism is installed around the main shaft and usually includes a mounting plate and a mounting seat for mounting and fixing the tire to be tested.

[0003] The existing main shaft and fixing mechanism are located at a certain height above the ground. When loading and unloading the tire to be tested, the tire needs to be manually lifted to align with the main shaft and fixing mechanism before it can be installed on the tire balancer. Due to the large weight of car tires, it is time-consuming and laborious for workers to move the tires up and down for a long time, which is inconvenient for the testing operation.

[0004] Therefore, the inventors have provided a tire balancer for automobile maintenance in order to solve the above problems. Utility Model Content

A lifting bracket is slidably connected to the balancing machine body on the same side as the main shaft. A driving structure for driving the lifting bracket to slide vertically is provided inside the balancing machine body. The lifting bracket includes a driven plate slidably connected to both sides of the balancing machine body and driven by the driving structure, a connecting frame disposed on the driven plate for supporting the tire, and a handle fixed to the end of the connecting frame.

[0007] Furthermore, the connecting frame includes a fixed sleeve fixedly connected to the driven plate, a driven sleeve fixedly connected to both ends of the bottom of the handle, and a slide rod fixedly connected to the end of the driven sleeve and sliding within the fixed sleeve.

[0008] Furthermore, the driven sleeve is provided with an inclined plate on its outer side, one end of which can abut against the ground, and the other end is provided with a hook that can hook onto the driven sleeve.

[0009] Further, the inner side of the driven sleeve is fixedly connected with a support plate, and a support roller for supporting the tire is rotatably connected to the support plate.

[0010] Further, a baffle plate is further included, and the bottom of the baffle plate is fixedly connected to the connection between the driven sleeve and the handle.

[0011] Further, vertical sliding grooves are formed on both sides of the balancing machine body, and a connecting piece is fixedly connected between the driven plates on the inner side of the balancing machine body.

[0012] Further, the connecting piece is a sleeve ring, the driving structure includes a screw rod rotatably connected to the balancing machine body and vertically arranged, a driving motor arranged in the balancing machine body, and a transmission gear arranged between the output shaft of the driving motor and the screw rod, and the sleeve ring is internally provided with an internal thread engaged with the screw rod.

[0013] The principle and effect of the present application are as follows:

[0014] Compared with the prior art, the tire to be detected can be placed on the connecting frame of the lifting support, and after being placed, the driven plate of the lifting support is driven to rise and fall by the driving structure, so that the tire can be lifted and lowered synchronously, and after the tire is aligned with the main shaft and the fixing structure on the main shaft, the tire on the connecting frame can be pushed onto the main shaft and fixed by the fixing structure, thereby replacing manual carrying, solving the problem that the traditional automobile tire balancing machine needs to manually lift the tire when loading and unloading the tire to be detected, and the worker needs to carry the tire to be detected up and down for a long time, which is time-consuming and laborious and inconvenient for detection operation.
