[0002] In the optical communication packaging industry, lifting mechanisms are commonly used equipment. The existing lifting mechanisms are driven by linear cylinders or motors to lift the tray. The problems are: 1. The output torque is small under limited volume, and the stability is poor and the service life is short when dealing with many high-load application scenarios. 2. The movement stroke of the linear lifting mechanism is determined by the stroke of the piston, and sufficient operating space needs to be reserved in the equipment, and the equipment has high space requirements. Summary of the invention

[0003] In view of the above-mentioned existing technical problems, the utility model provides a rotary lifting mechanism, which is suitable for high-load application scenarios, has good stability and occupies less space.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions: a rotary lifting mechanism, comprising a cylinder fixing seat, a rotary cylinder, a groove fixing plate and a guide rail; an opening for a cylinder air inlet interface is left on one side of the cylinder fixing seat; the rotary cylinder is installed in the cylinder fixing seat, and the cylinder air inlet interface is connected to the rotary cylinder through the opening, and the main shaft of the rotary cylinder is tightened and connected to the eccentric wheel through a tightening block, and the eccentric wheel is connected to the U-shaped groove; the groove fixing plate is fixedly connected to the slider mounting plate, and the bottom of the slider mounting plate is fixedly connected to the U-shaped groove, and the groove fixing plate, the slider mounting plate and the U-shaped groove form an integrated structure; the guide rail is fixed on the top of the cylinder fixing seat, and the U-shaped groove is slidably arranged on the guide rail; the rotary cylinder rotates to drive the eccentric wheel to rotate, and the slider mounting plate and the U-shaped groove have an up and down displacement difference in the guide rail driven by the eccentric wheel, thereby driving the groove fixing plate to move up and down.

[0005] The utility model further provides that a proximity switch fixing seat is installed on the drag groove fixing plate, a proximity switch is installed on the proximity switch fixing seat, and an upper sensing sheet is connected to one side of the slider mounting plate.

[0006] Furthermore, in the utility model, a sensor fixing bracket is connected to one side of the cylinder fixing seat, and a photoelectric sensor is installed on the sensor fixing bracket.

[0007] Furthermore, the utility model provides that rectangular, circular and elongated installation holes are reserved on the ditch fixing plate.

[0008] Furthermore, the utility model provides that the cylinder fixing seat is a frame structure, with an installation space for the rotating cylinder reserved in the center, and a support seat formed at the bottom and a mounting hole reserved therein.

[0009] The beneficial effect of adopting the above technical solution is that the utility model adopts a rotary cylinder to drive the lifting movement of the drag groove fixing plate. Compared with the existing linear cylinder or motor, it can generate a larger output torque in a smaller volume, which enables the utility model to cope with many high-load application scenarios, and the rotary cylinder converts rotary motion into linear motion, so that the space it occupies is much smaller than the traditional linear cylinder and motor combination, and it is more suitable for use in applications with limited space.
