[0021] Below, the utility model is further described with reference to the accompanying drawings and specific embodiments:

[0022] See also Figure 1-3 According to an embodiment of the present invention, a lifting device for a special-shaped acrylic plate includes four universal wheels 1, which are respectively installed at the four corners of the bottom of a base plate 2. A support cylinder 3 is fixedly installed in the upper middle part of the base plate 2, and a drive box 4 is installed on the top of the support cylinder 3. A lifting mechanism 5 is installed in the drive box 4, and a lifting mechanism 6 is installed on the top of the lifting mechanism 5.

[0023] Among them, the universal wheel 1 facilitates the movement of personnel during use, the bottom plate 2 ensures the stability of the bottom of the device when lifting, and the lifting mechanism 5 is used to lift the lifting mechanism 6, which is used to adapt to various special-shaped acrylic panels.

[0024] In this embodiment, a lifting hole 7 is opened through the middle of the upper and lower parts of the driving box 4 and is connected to the support tube 3. A lifting rod 8 on the lifting mechanism 5 is arranged in the support tube 3. The top end of the lifting rod 8 passes through the lifting hole 7. A rack 9 is opened on the side of the lifting rod 8, and the rack 9 engages with the first gear 10 on the side.

[0025] The first gear 10 drives the rack 9 to move upward, thereby driving the lifting rod 8 to rise.

[0026] In this embodiment, the first gear 10 is fixedly mounted in the middle of the first rotating rod 11, and the two ends of the first rotating rod 11 are rotatably mounted on the inner wall of the drive box 4 through bearings. The second gear 12 is fixedly mounted on the first rotating rod 11, and the second gear 12 engages with the third gear 13 above it. The third gear 13 is fixedly mounted on the second rotating rod 14, and the two ends of the second rotating rod 14 pass through the side wall of the drive box 4 and are rotatably mounted through bearings.

[0027] The second rotating rod 14 drives the third gear 13 to rotate, the third gear 13 drives the second gear 12 to rotate, the second gear 12 drives the first rotating rod 11 to rotate, and the first rotating rod 11 drives the first gear 10 to rotate.

[0028] In this embodiment, a turning handle 15 is fixedly installed at one end of the second turning rod 14, and a ratchet 16 is fixedly installed at the other end of the second turning rod 14. When the ratchet 16 rotates clockwise, it engages with one side of the pawl 17. A spring 18 is fixedly connected between the other side of the pawl 17 and the baffle on the side wall of the drive box 4. The middle part of the pawl 17 is installed on the side wall of the drive box 4 through a rotating part.

[0029] The operator rotates the handle 15 to drive the second rotating rod 14 to rotate. The cooperation between the pawl 17 and the ratchet 16 prevents the second rotating rod 14 from reversing. The spring 18 resets the pawl 17 .

[0030] In this embodiment, a sealing box 19 on the lifting mechanism 6 is fixedly installed on the top of the lifting rod 8. A plurality of sliding holes 20 are opened through the top of the sealing box 19. A slide cylinder 21 is fixedly installed between the sliding holes 20 and the bottom of the sealing box 19. A vent 22 is opened through the bottom end of the slide cylinder 21 and is connected to the interior of the sealing box 19.

[0033] Among them, a part of the lifting rod 24 is lowered by the gravity exerted by the acrylic plate, thereby driving the sealing plug 23 below it to fall. Since the gas in the sealing box 19 is compressed, the compressed gas will lift up the other part of the sealing plug 23, thereby lifting the lifting rod 24, so that each group of rubber pads 25 can contact the special-shaped acrylic plate to ensure uniform force.

[0034] In specific application, first move the device to a suitable position through the universal wheel 1, and place the special-shaped acrylic plate on the rubber pad 25. At this time, a part of the lifting rod 24 is lowered by the gravity exerted by the acrylic plate, thereby driving the sealing plug 23 below it to descend. Since the gas in the sealing box 19 is compressed, the compressed gas will push up the other part of the sealing plug 23, thereby lifting the lifting rod 24, so that each group of rubber pads 25 can contact the special-shaped acrylic plate to ensure uniform force. Then the personnel rotates the handle 15 to drive the second rotating rod 14 to rotate, the second rotating rod 14 drives the third gear 13 to rotate, the third gear 13 drives the second gear 12 to rotate, the second gear 12 drives the first rotating rod 11 to rotate, the first rotating rod 11 drives the first gear 10 to rotate, the first gear 10 drives the rack 9 to move up, and the rack 9 drives the lifting rod 8 to rise, thereby lifting the special-shaped acrylic plate. The cooperation of the pawl 17 and the ratchet 16 prevents the second rotating rod 14 from reversing, thereby ensuring the stability of the lifting.
