[0004] The purpose of the utility model is to solve the technical problems in the above background, and to propose a jacking mechanism and a multi-layer driven lifting device for a stage.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a lifting mechanism and a multi-layer driven lifting device for a stage, comprising a lifting frame, a control panel fixedly installed on the side of the lifting frame, and lifting devices are provided on both side surfaces of the lifting frame, and the lifting device comprises two through slots, the two through slots are provided on both side surfaces of the lifting frame, and vertical rods are fixedly installed between the inner walls at both ends of the two through slots, and three slides are slidably connected on the surfaces of the two vertical rods, wherein a first bearing plate, a second bearing plate and a third bearing plate are fixedly installed between every two of the slides, and four connecting rods are fixedly installed between the first bearing plate and the second bearing plate and between the second bearing plate and the third bearing plate. The setting of the slides and the vertical rods has the effect of limiting the position of the moving direction of the first bearing plate, the second bearing plate and the third bearing plate.

[0006] Preferably, four cylinders are fixedly mounted on the bottom surface of the lifting frame, two extension plates are fixedly mounted on both side surfaces of the first bearing plate, the output end of the cylinder is fixedly connected to the extension plate, and the cylinder is electrically connected to the control panel. The arrangement of the cylinder and the extension plate has the effect of driving the first bearing plate to move.

The setting of the hinge plate plays an effect of driving the slider to move inside the slide groove.

[0008] Preferably, a protective device is provided on the side of the lifting frame, and the protective device includes two vertical slots, the two vertical slots are opened on the side of the lifting frame, and a protective plate is slidably connected between the two vertical slots. The setting of the protective plate plays an effect of protecting the control panel.

[0009] Preferably, a groove is provided on the side of the protective plate, a displacement plate is slidably connected inside the groove, a plug rod is fixedly installed on the surface of the displacement plate, and a plurality of plug holes are evenly provided on the side of the lifting frame.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, a lifting device is provided. When the device needs to be used, the cylinder is first controlled to start through the control panel, and the cylinder starts to drive the extension plate to move. The extension plate movement drives the first bearing plate to move. The first bearing plate movement drives the hinged plate to move. The hinged plate movement pulls the two slide blocks to move in the direction of approaching each other inside the slide groove. At the same time, the movement of the first bearing plate also drives the slide plate to move on the surface of the vertical rod while also driving the connecting rod to move. The movement of the connecting rod drives the second bearing plate to move. The movement of the second bearing plate drives the connecting rod to move. The movement of the connecting rod drives the third bearing plate to move. When the third bearing plate, the first bearing plate and the second bearing plate move to a suitable height, the cylinder can be controlled to close again through the control panel. Through the cooperation of the above structure, the device adopts a jacking method to replace the previous traction form of wire rope + pulley, which effectively improves the stability and reliability of the lifting platform.

[0013] 2. In the utility model, by setting a protective device, when it is necessary to protect the control panel, first slide the displacement plate to make the displacement plate move inside the groove. The movement of the displacement plate inside the groove will squeeze the spring, so that the spring is compressed. At the same time, the movement of the displacement plate inside the groove also drives the insertion rod to move. The movement of the insertion rod causes it to move out of the inside of the insertion hole. The insertion rod and the insertion hole are separated, so that the protective plate loses its limit in the vertical groove. At this time, the protective plate can be moved to make the protective plate move inside the vertical groove. When the position of the protective plate inside the vertical groove completes covering the control panel, the displacement plate is released, and the resilience of the spring is used to reinsert the insertion rod into the corresponding insertion hole to fix the position of the protective plate inside the vertical groove at this time. Through the cooperation of the above structure, the protective plate can protect the control panel, thereby avoiding accidental touching of the control panel and causing safety accidents.
