The rotating rod and the sliding rod are hinged in the middle, and one end of the rotating rod is driven by a worm gear The mechanism is fixed, the other end is hinged with the carrier plate, one end of the sliding rod is hinged with the slider, and the other end is hinged with the carrier plate, the slider is set on the slide rail, the transmission motor is connected with the worm, and the slide rail is installed On one side of the bottom plate, the controller is connected to the transmission motor, and the hand push rod is connected to the bottom plate. This new type of lifting logistics trolley can quickly lift and lower the carrier plate, with high stability and high automation level.

Preferably, the rollers are universal wheels with self-locking function.

The beneficial effect of adopting the above technical solution is that the rollers with the structure of the utility model avoid random sliding of the logistics trolley, and have high safety and stability.

Preferably, the worm gear transmission mechanism in the lifting mechanism includes a worm and a worm gear, the worm gear meshes with the worm, and the helix angle of the worm is smaller than the equivalent friction angle between the meshing teeth of the worm and the worm gear.

The beneficial effects of adopting the above technical solutions are: the lifting mechanism of the utility model has a compact structure, high bearing capacity, self-locking capability, and high safety performance.

Preferably, limit blocks are provided on both sides of the slide rail.

The beneficial effect of adopting the above technical solution is that the limit block of the utility model structure can limit the moving distance of the slider, that is, limit the upper and lower limit heights of the carrier plate.

Preferably, the controller is provided with up and down buttons.

The beneficial effect of adopting the above technical solution is: the logistics trolley with the structure of the utility model can realize the lifting and lowering of the carrier board by pressing the up and down buttons, and has a high level of automation.
