[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown in the figure, the present invention provides a hoisting structure for a hoisting screen, including a frame 1, a lead screw 2, a motor 3, and a moving block 4. The lead screw 2 is rotatably connected to the inside of the frame 1, the motor 3 is fixedly connected to the inside of the frame 1, and the output end of the motor 3 is fixedly connected to the top of the lead screw 2. The moving block 4 is threadedly connected to the surface of the lead screw 2. The front side of the frame 1 is provided with a moving hole 5 corresponding to the lead screw 2. The front side of the frame 1 is provided with a placement plate 6, the rear side of the placement plate 6 is fixedly connected to the front side of the moving block 4, and the left and right sides of the rear side of the placement plate 6 are fixedly connected with lifting extension clamping devices 7.

[0022] refer to Figure 1 and Figure 4 The lifting and extending clamping device 7 includes a first double-headed electric cylinder 701, two connecting blocks 702, two lifting arms 703, two extension boxes 704, a cavity 705, two electric cylinders 706, and two clamping plates 707. The first double-headed electric cylinder 701 is fixedly connected to the rear side of the placement plate 6. The two connecting blocks 702 are respectively fixedly connected to the two output ends of the first double-headed electric cylinder 701. The two lifting arms 703 are respectively located at the top and bottom of the placement plate 6 and in front of the two connecting blocks 702. 703 is slidably connected to the inside of the placement plate 6, and the rear side of the lifting arm 703 is fixedly connected to the front side of the connecting block 702. Two extension boxes 704 are fixedly connected to the top and bottom of the two lifting arms 703 respectively. Cavities 705 are opened inside the two extension boxes 704. Two electric cylinders 706 are fixedly connected to the inside of the cavities 705 of the two extension boxes 704 respectively, and their output ends pass through and extend out of the front side of the extension box 704. Two clamping plates 707 are fixedly connected to the output ends of the two electric cylinders 706 respectively.

[0023] The above solution allows for the adjustment of dimensions by setting up a lifting and extending clamping device 7, which can clamp and position placement frames 8 of different sizes as needed.

[0024] refer to Figure 1 and Figure 2 A placement frame 8 is provided on the front side of the placement plate 6. The top and bottom of the placement frame 8 are in contact with the top and bottom of the two oppositely arranged extension boxes 704, and the front side of the placement frame 8 is in contact with the rear surface of the clamping plate 707.

[0025] The above solution is adopted: by setting up the placement frame 8, the screen 14 that needs to be hoisted can be placed, thereby improving the stability of the screen 14 within the placement frame 8.

[0026] refer to Figure 3 The left and right sides of the placement frame 8 are fixedly connected to clamping boxes 9. The clamping boxes 9 have a placement cavity 10 inside, and the placement cavity 10 is equipped with a clamping mechanism 11 and a driving mechanism 12.

[0027] By adopting the above solution, by setting up a clamping box 9, a placement cavity 10, a clamping mechanism 11 and a driving mechanism 12, the screen 14 set in the placement frame 8 can be positioned by the mechanism set in the clamping box 9, thereby improving the stability of the screen 14 in the placement frame 8.

[0028] refer to Figure 3 The clamping mechanism 11 includes two transmission blocks 1101, two clamping blocks 1102, and two tension springs 1103. The two transmission blocks 1101 are respectively disposed on both sides inside the placement cavity 10. The two clamping blocks 1102 are respectively fixedly connected to the side of the two transmission blocks 1101 near the placement frame 8, and the other side of the clamping blocks 1102 extends through and into the inner side of the placement frame 8. The two tension springs 1103 are respectively fixedly connected to the side of the two transmission blocks 1101 near the placement frame 8, and the other end of the tension springs 1103 is fixedly connected to the inside of the placement cavity 10. The surface of the transmission block 1101 is provided with a transmission hole 13, which is used in conjunction with the drive mechanism 12.

[0029] The above solution is adopted: by setting a clamping mechanism 11, the clamping mechanism 11 can contact the outer frame of the screen 14 after passing through the placement frame 8 and clamp it, thereby fixing the screen 14 stably inside the placement frame 8.

[0030] refer to Figure 3The drive mechanism 12 includes an I-beam frame 1201, a second double-headed electric cylinder 1202, two lifting blocks 1203, and two push columns 1204. The I-beam frame 1201 is fixedly connected to the right side inside the placement cavity 10, the second double-headed electric cylinder 1202 is fixedly connected to the left side of the I-beam frame 1201, the two lifting blocks 1203 are respectively fixedly connected to the two output ends of the second double-headed electric cylinder 1202, and the two push columns 1204 are respectively fixedly connected to the rear side of the two lifting blocks 1203. The push columns 1204 are inserted into the inside of the transmission hole 13, and the surface of the push columns 1204 is in contact with the inner wall of the transmission hole 13.

[0031] By adopting the above solution, the clamping mechanism 11 can be moved by setting the driving mechanism 12, thereby improving the assembly flexibility of the screen 14 and the placement frame 8.

[0032] refer to Figure 2 and Figure 3 The frame 8 is equipped with a screen 14. The left and right sides of the screen 14 are in contact with the surfaces of the clamping blocks 1102 that run through the sides. The front side of the screen 14 is in contact with the rear side of the clamping plate 707.

[0033] The above solution is adopted: by setting the screen 14, the screen 14 can be positioned behind the placement frame 8 by the clamping block 1102, and then the front side of the screen 14 can be positioned by the clamping plate 707, thus preventing the screen 14 from moving within the placement frame 8.

[0034] The screen 14 to be hoisted is placed inside the placement frame 8. During assembly, the second electric cylinder 706 is activated, which drives the two lifting blocks 1203 to move closer to each other. As the lifting blocks 1203 move, they drive the push column 1204 to move. The push column 1204, in turn, presses against the inner wall of the transmission hole 13 on the surface of the transmission block 1101, thereby moving the transmission block 1101 away from the placement frame 8. As the transmission block 1101 moves, it drives the clamping block 1102 to move, simultaneously stretching the tension spring 1103. This completes the assembly of the screen 14 with the placement frame 8. The second double-headed electric cylinder 1202 is then activated again, and the movement of the clamping block 1102 clamps and positions the two sides of the screen 14. The assembled placement frame 8 is then placed in front of the placement plate 6. 8. During installation, the first double-headed electric cylinder 701 needs to be activated first, which drives the two lifting arms 703 to move. Then, the placement frame 8 can be placed in front of the placement plate 6. Then, the electric cylinder 706 is activated, which drives the clamping plate 707 to extend. At this time, the first double-headed electric cylinder 701 can be activated again, which drives the two lifting arms 703 to descend. Then, the top and bottom of the placement frame 8 can be clamped. After clamping, the electric cylinder 706 can be activated again, which drives the clamping plate 707 to retract. Then, the clamping plate 707 contacts the front of the screen 14, thus completing the positioning and installation of the placement frame 8. Then, the motor 3 can be activated, which drives the lead screw 2 to rotate. Then, the rotation of the lead screw 2 drives the threaded moving block 4 to move. Then, the moving block 4 can drive the placement plate 6 to move, thereby moving the screen 14.

[0035] In summary, the hoisting structure of this suspended screen, through the coordinated use of frame 1, lead screw 2, motor 3, moving block 4, moving hole 5, placement plate 6, lifting extension clamping device 7, placement frame 8, clamping box 9, placement cavity 10, clamping mechanism 11, drive mechanism 12, transmission hole 13 and screen 14, solves the problem that the suspended screen needs to be regularly inspected after use to ensure normal operation. However, the inspection process requires disassembly, which is cumbersome and reduces the efficiency of the inspection.

Furthermore, the specific composition and principle of the power supply of the motor, the first double-headed electric cylinder, the second double-headed electric cylinder, and the electric cylinder are clear to those skilled in the art, and therefore will not be described in detail.
