[0027] like Figures 1 to 5As shown, an ecological lightweight partition board comprises a partition board 1 and two sets of guide rails 4, the front and rear outer walls of the two sets of guide rails 4 are fitted to the front and rear inner walls of the upper and lower ends of the partition board 1, a groove is provided inside the partition board 1, a driving mechanism 2 for driving the partition board 1 to slide between the two sets of guide rails 4 is provided inside the groove, two sets of positioning mechanisms 6 are provided inside the driving mechanism 2, and a protective mechanism 3 is installed inside the driving mechanism 2; specifically, the driving mechanism 2 can be disassembled during use, thereby reducing the quality of subsequent partition boards 1 during installation and disassembly, and thus facilitating subsequent staff to install and disassemble the ecological partition board 1, thereby improving the practicality of the device; the positioning mechanism 6 is used to tighten the internal disassembly part of the driving mechanism 2, so that the driving mechanism 2 is not easy to disconnect during use, thereby improving the stability of the subsequent driving mechanism 2 during use.
[0028] like Figures 1 to 3 As shown, the driving mechanism 2 includes two groups of fixed plates 202, a positioning plate 205, a fixed sleeve 201 and a fixed block 206. The upper and lower surfaces of the partition board 1 are provided with card grooves. The two groups of positioning plates 205 are respectively slidably connected to the inside of the two groups of card grooves of the partition board 1. The right inner wall of the partition board 1 is provided with a positioning groove. The fixed block 206 is installed in the groove of the partition board 1. A bearing 207 is provided inside the fixed block 206. A fixing rod 208 is installed on the inner wall of the bearing 207. A bevel gear 1 209 is installed on the outer surface of the fixing rod 208. The external teeth of the bevel gear 1 209 are meshed and connected with the bevel gear 2 210. The side of the bevel gear 210 away from the bevel gear 1 209 is installed on the fixed sleeve 201. On one side of the near fixing rod 208, the external thread of the fixing rod 208 is connected with two sets of sliders 211, and the opposite sides of the two sets of sliders 211 are respectively installed on the adjacent sides of the two sets of positioning plates 205. The left and right inner walls of the two sets of guide rails 4 are provided with card grooves, and the two sets of fixing plates 202 are respectively slidably connected to the two sets of card grooves of the two sets of guide rails 4. The adjacent sides of the two sets of fixing plates 202 are provided with card grooves, and the positions of the internal card grooves of the two sets of fixing plates 202 are respectively located on the moving paths of the two sets of positioning plates 205. The opposite sides of the two sets of fixing plates 202 are provided with directional pulleys 203, and the two sets of directional pulleys 203 include rollers 204. The opposite sides of the two sets of rollers 204 respectively abut against the inner walls of the opposite sides of the two sets of guide rails 4;
[0029] Specifically, by rotating the two sets of fixing sleeves 201, the bevel gear 210, the bevel gear 1 209 and the fixing rod 208 drive the two sets of sliders 211 to slide inside the grooves of the partition board 1, so that the two sets of sliders 211 push the two sets of positioning plates 205 to move during the movement, and the opposite ends of the two sets of positioning plates 205 are respectively clamped in the slots of the two sets of fixing plates 202, and then the partition board 1 is pushed to drive the two sets of fixing plates 202 and the two sets of directional pulleys 203 to slide inside the two sets of guide rails 4, so that the partition board 1 is moved to the installation area, thereby completing the installation of the partition board 1; by rotating the fixing sleeve 201, the two sets of positioning plates 205 are driven to move, so that the two sets of fixing plates 202 and the two sets of positioning plates 205 can be disconnected during use, thereby reducing the quality of the subsequent partition board 1 during the installation and removal process, and making it easier for subsequent staff to install and remove the ecological partition board 1, thereby improving the practicality of the device.
[0030] At the same time, the fixing plate 202 and the positioning plate 205 can be disassembled, so that the driving mechanism 2 can be disassembled and replaced when damaged, thereby reducing the replacement cost consumed by subsequent staff in the process of replacing the driving mechanism 2, thereby improving the practicality of the device.
[0031] like Figure 2 and Figure 5 As shown, grooves are provided on the front and rear inclined surfaces of the two sets of guide rails 4, and silicone pads 5 are glued to the inside of the two sets of grooves of the two sets of guide rails 4; specifically, multiple sets of silicone pads 5 are respectively abutted against the front and rear inclined surfaces of the upper and lower ends of the partition board 1 on one side away from the adjacent set of guide rails 4, so that multiple sets of silicone pads 5 disconnect the two sets of guide rails 4 and the partition board 1, thereby avoiding as much as possible the friction between the front and rear inclined surfaces of the upper and lower ends of the partition board 1 and the front and rear inclined surfaces of the two sets of guide rails 4 when the subsequent staff pushes the partition board 1 to move, causing the partition board 1 to make noise during the movement.
[0032] like Figure 2 and Figure 5 As shown, rubber rings 7 are bonded to the outer surfaces of the two groups of rollers 204, and multiple groups of guide grooves are provided on the outer surfaces of the two groups of rubber rings 7. The opposite sides of the two groups of rubber rings 7 are respectively in contact with the inner walls of the opposite sides of the two groups of guide rails 4; specifically, multiple groups of guide grooves are provided on the outer surfaces of the rubber rings 7, so that the air squeezed by the rubber rings 7 during rotation floats along the multiple groups of guide grooves to both sides of the rollers 204, and then the two groups of rubber rings 7 are respectively installed on the outer surfaces of the two groups of rollers 204, so as to avoid the two groups of rollers 204 from making loud noises during the subsequent sliding of the partition board 1 inside the two groups of guide rails 4, thereby improving the comfort of subsequent staff when installing the partition board 1.
[0033] like Figure 2 and Figure 5 As shown, the two sets of positioning mechanisms 6 include two sets of iron sheets 601 and two sets of magnetic blocks 602. The inner walls of the opposite sides of the two sets of fixed plates 202 are provided with grooves. The two sets of iron sheets 601 are respectively installed inside the grooves of the two sets of fixed plates 202. The opposite sides of the two sets of positioning plates 205 are provided with card slots. The two sets of magnetic blocks 602 are respectively installed inside the card slots of the two sets of positioning plates 205. The positions of the two sets of iron sheets 601 are respectively located on the moving paths of the two sets of magnetic blocks 602. Specifically, through the opposite sides of the two sets of positioning plates 205, When one side is attached to the inner wall of the opposite side of the two sets of fixed plates 202, the opposite sides of the two sets of magnetic blocks 602 are respectively adsorbed on the adjacent sides of the two sets of iron sheets 601, thereby allowing the two sets of positioning mechanisms 6 to limit the positions of the two sets of positioning plates 205 inside the card slots of the two sets of fixed plates 202, thereby minimizing the subsequent sliding of the two sets of positioning plates 205 inside the card slots of the two sets of fixed plates 202 during use, thereby improving the stability of the subsequent positioning plates 205 when they are clamped inside the card slots of the fixed plates 202.
[0034] like Figure 4 As shown, the protection mechanism 3 includes a spring telescopic rod 301 and a protection cover 302, the protection cover 302 is slidably connected to the inner wall of the groove of the fixed sleeve 201, the spring telescopic rod 301 is installed at the bottom of the inner wall of the groove of the fixed sleeve 201, the side of the spring telescopic rod 301 away from the inner wall of the fixed sleeve 201 is installed on the side of the protection cover 302 close to the fixed rod 208, and the side of the protection cover 302 away from the spring telescopic rod 301 and the side of the fixed sleeve 201 away from the fixed rod 208 are kept parallel; specifically, the side of the protection cover 302 away from the spring telescopic rod 301 and the side of the fixed sleeve 201 away from the fixed rod 208 are kept parallel. One side remains parallel, so that the protective mechanism 3 blocks the inside of the groove of the fixed sleeve 201, thereby minimizing the possibility that dust and debris enter the groove of the fixed sleeve 201 during the subsequent idle process, causing the subsequent staff to be unable to insert the driving tool into the groove of the fixed sleeve 201; by pushing the driving tool, the protective cover 302 pushes the spring telescopic rod 301 for compression, and the driving tool is inserted into the groove of the fixed sleeve 201, thereby minimizing the possibility that the driving tool cannot be inserted into the groove of the fixed sleeve 201 when the subsequent protective mechanism 3 blocks and protects the inside of the groove of the fixed sleeve 201.
[0035] In summary: by rotating the two sets of fixed sleeves 201, the bevel gear 210, the bevel gear 1 209 and the fixed rod 208 are triggered to drive the two sets of sliders 211 to slide inside the groove of the partition board 1, so that the two sets of sliders 211 can push the two sets of positioning plates 205 to move during the movement, and the opposite ends of the two sets of positioning plates 205 are respectively clamped in the grooves of the two sets of fixed plates 202, and then the partition board 1 is pushed to drive the two sets of fixing plates 202 and the two sets of directional pulleys 203 to slide inside the two sets of guide rails 4, so that the partition board 1 is moved to the installation area, thereby completing the installation of the partition board 1; by rotating the fixed sleeve 201, the two sets of positioning plates 205 are driven to move, so that the two sets of fixing plates 202 and the two sets of positioning plates 205 can be disconnected during use, thereby reducing the quality of the subsequent partition board 1 during the installation and disassembly process.
[0036] At the same time, by keeping the side of the protective cover 302 away from the spring telescopic rod 301 and the side of the fixed sleeve 201 away from the fixed rod 208 parallel, the protective mechanism 3 blocks the interior of the groove of the fixed sleeve 201, thereby minimizing dust and debris from entering the groove of the fixed sleeve 201 during the subsequent idle process, which may cause the subsequent staff to be unable to insert the driving tool into the groove of the fixed sleeve 201; by pushing the driving tool, the protective cover 302 pushes the spring telescopic rod 301 to be compressed, and the driving tool is inserted into the groove of the fixed sleeve 201, thereby minimizing the subsequent protection mechanism 3 from being unable to insert the driving tool into the groove of the fixed sleeve 201 when the protective mechanism 3 blocks the interior of the groove of the fixed sleeve 201 for protection.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
