[0030] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0032] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0033] like Figures 1 to 6 As shown, the lifting mechanism of the polygonal panel of the present invention includes: a support assembly 1, a plurality of screw lifting assemblies 2 and a drive assembly 3. The support assembly 1 has a first support member 101 for supporting the polygonal panel, and the plurality of screw lifting assemblies 2 are connected to the support assembly 1. The plurality of screw lifting assemblies 2 work simultaneously to control the synchronous rise and synchronous descent of the support assembly 1 as a whole. The drive assembly 3 includes a motor 31 and a transmission belt 32. The transmission belt 32 is simultaneously connected to the plurality of screw lifting assemblies 2 with a transmission. The motor 31 drives the plurality of screw lifting assemblies 2 to work simultaneously through the transmission belt 32. When the output shaft of the motor 31 rotates in the forward direction, it can drive the support assembly 1 to rise synchronously as a whole; when the output shaft of the motor 31 rotates in the reverse direction, it can drive the support assembly 1 to descend synchronously as a whole.

[0034] That is to say, the lifting mechanism adopts only one driving source, and drives multiple screw lifting assemblies 2 to move through the transmission belt 32 to synchronously lift the polygonal panel, thereby improving the synchronization of different positions of the polygonal panel when being lifted.

[0035] The support assembly 1 also includes: a second support member 102 and a support plate 103. The support plate 103 is connected to multiple screw jacking assemblies 2. Multiple first support members 101 are arranged at the edges of the support plate 103, and the second support member 102 is arranged in the middle of the support plate 103. The first support member 101 corresponds to the edge of the polygonal panel, and the second support member 102 corresponds to the middle of the polygonal panel. The second support member 102 assists the multiple first support members 101 to jointly support the polygonal panel. The multiple screw jacking assemblies 2 are spaced apart and enclosed into a shape that matches the shape of the polygonal panel. For example, the upper end of the first support member 101 is provided with a support step surface 1011 for abutting the edge of the polygonal panel. When the polygonal panel falls on the first support member 101, the edge of the panel will be limited by the side wall of the support step surface 1011, preventing the polygonal panel from shifting or falling on the support assembly 1 during operation. For example, the number of the second support member 102 is one, the number of the first support members 101 is twelve, and three first support members 101 are provided on each side of the support plate 103. Of course, the number of the first support members 101 is not limited thereto.

[0036] Specifically, the drive assembly 3 is mounted on the base plate 4. A drive mounting plate 41 is provided on the base plate 4, and the motor 31 is mounted on the drive mounting plate 41. The polygonal panel can be in the shape of a quadrilateral, a pentagon, a hexagon, etc. The number of screw jacking assemblies 2 matches the number of sides of the polygonal panel. The screw jacking assembly 2 includes a screw rod 21 and a lifting nut 22, and the screw rod 21 and the lifting nut 22 are threadedly connected. The lower end of the screw rod 21 is movably connected to the base plate 4, and the upper end of the screw rod 21 passes through the support plate 103, and the lifting nut 22 is fixedly connected to the support plate 103. A mounting hole is provided on the base plate 4, and a connecting block 7 is installed in the mounting hole. The lower end of the screw rod 21 is connected to the connecting block 7 through a bearing 8. That is, the screw rod 21 is rotatable and is not fixed. The driving assembly 3 also includes: multiple transmission wheels 33 and multiple idler wheels 34. The idler wheels 34 are rotatably connected to the base plate 4. The transmission wheels 33 are installed at the lower end of the screw rod 21. The transmission belt 32 is wound around the transmission wheels 33 and the idler wheels 34 to realize belt transmission.

[0037] For example, in a quadrilateral panel, there are four sets of screw jacking assemblies 2, which are respectively arranged at the four corner areas of the base plate 4. For example, there are five transmission wheels 33 and four idler wheels 34. The output end of the motor 31 faces downward, one transmission wheel 33 is connected to the output shaft of the motor 31, and the remaining four transmission wheels 33 are respectively connected to the four sets of screw jacking assemblies 2. The four idler wheels 34 are respectively installed near the four sets of screw jacking assemblies 2. The five transmission wheels 33 are respectively recorded as transmission wheels a, b, c, d, and e, and the four idler wheels 34 are respectively recorded as idler wheels A, B, C, and D. The transmission wheels a, b, c, d, and e are arranged in a clockwise direction, and the idler wheels A, B, C, and D are arranged in a clockwise direction. The transmission belt 32 then passes around the transmission wheel a, idler wheel A, transmission wheel b, transmission wheel c, idler wheel B, idler wheel C, transmission wheel d, transmission wheel e, and idler wheel D in turn. When the motor 31 drives the transmission wheel a to rotate, the transmission belt 32 can drive the transmission wheels b, c, d, and e to rotate at the same time, thereby driving the four sets of screw lifting assemblies 2 to move simultaneously.

[0038] Specifically, the transmission wheel 33 is connected to the screw rod 21. When the transmission wheel 33 rotates, it can drive the screw rod 21 to rotate. When the screw rod 21 rotates, the lifting nut 22 is moved up and down through the thread. Therefore, this embodiment improves the mounting structure of the lower end of the screw rod 21 to facilitate the rotation of the screw rod 21. When the lifting nut 22 moves up and down, it can drive the support plate 103 to move up and down. When the transmission belt 32 is driven, the idler wheel 34 will also rotate. Therefore, the idler wheel 34 and the base plate 4 are also movably connected. The lower end of the idler wheel connector 10 is inserted into the base plate 4 and is fixed to the base plate 4 by threads. The upper end of the idler wheel connector 10 is located outside the base plate 4 and is rotationally connected to the idler wheel 34.

[0039] For example, the base plate 4 is also provided with a guide assembly 5, which is used to guide the up and down movement of the support assembly 1. The guide assembly 5 includes a guide post 51 and a guide block 52. The guide block 52 is slidably connected to the guide post 51, and the guide post 51 is fixedly connected to the base plate 4. The upper end of the guide post 51 extends through the support plate 103, and the guide block 52 is fixedly connected to the support plate 103. When the support plate 103 moves up and down driven by the screw lifting assembly 2, the guide block 52 also slides up and down on the guide post 51. For example, four sets of screw lifting assemblies 2 are located in the four corners of the support plate 103, and four sets of guide assemblies 5 are evenly distributed in the middle of the support plate 103. Due to the large size of the panel, the support plate 103 of this embodiment is also large. The provision of the guide assembly 5 can improve the stability of the support plate 103 during up and down movement. For example, the support plate 103 is provided with multiple weight-reducing holes 1031. The reduced weight of the support plate 103 further improves its stability during up and down movement.

[0040] Working process:

[0041] The polygonal panel is transported to the top of the lifting mechanism. The motor 31 is then activated, driving the drive belt 32 to rotate the multiple drive wheels 33 and idler wheels 34, causing the screw 21 to rotate. As the screw 21 rotates, the lifting nut 22 drives the support plate 103 upward. Simultaneously, the guide block 52 slides upward on the guide post 51. Once the first and second support members 101, 102 contact the polygonal panel, the support assembly 1 continues to move upward, lifting the polygonal panel. When the polygonal panel reaches the specified height, the motor 31 stops.

[0042] In summary, the lifting mechanism of the present invention, through structural improvements, is suitable for lifting polygonal panels. Through the cooperation of a motor 31 and a transmission belt 32, the synchronous rotation of multiple screw rods 21 can be achieved, thereby achieving synchronous lifting of different positions of the support plate 103, which is beneficial to improving the synchronization and stability when lifting different positions of the polygonal panel.
