Description

Technical Field

[0001] This utility model relates to the field of building decoration technology, specifically a lightweight polyvinyl chloride composite board. Background Technology

[0002] In the functional design of contemporary open-plan offices, exhibition halls, and multi-functional halls, the need for low-height partitions is becoming increasingly prominent, in addition to the requirement for complete separation. Taking open-plan offices as an example, employees need to maintain a spacious environment for communication and collaboration while also dividing workstations at low heights to avoid visual interference between adjacent workstations, without compromising the overall sense of openness. In exhibition halls hosting small themed exhibitions, low-height partitions are needed to divide different exhibit areas, guiding visitor flow while ensuring the continuity of the overall exhibition space and avoiding the disruption of the exhibition atmosphere caused by high partitions. In multi-functional halls hosting training sessions or small meetings, low-height partitions can be used to divide group discussion areas, ensuring the relative independence of each group while allowing instructors to observe the dynamics of each area, thus improving interaction efficiency.

[0003] In existing technologies, some public spaces use fixed low-height partitions. Once installed, these partitions cannot be adjusted in height or hidden away according to usage needs. When the space needs to be restored to a fully open state, the fixed partitions become an obstacle to the spatial layout and cannot meet the need for on-demand switching. At the same time, they are not adaptable to different scenarios, as the height and width of fixed low-height partitions are fixed and cannot be adapted to different scenarios. Furthermore, some fixed low-height partitions use heavy materials, which, even at a low height, can bring a sense of oppression to the space and destroy the transparent atmosphere of the open space.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide a lightweight polyvinyl chloride composite sheet to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a lightweight polyvinyl chloride composite sheet, including an outer sheet, a fixed frame fixedly connected inside the outer sheet, a lead screw rotatably connected to one side of the inner wall of the outer sheet, a moving block threadedly connected to the outer wall of the lead screw, a first push plate fixedly connected to one side of the moving block, racks fixedly connected to the outer wall of the left side near the top and the outer wall of the right side near the bottom of the first push plate, a first gear meshing with the bottom end of the left rack and the top end of the right rack, a first connecting rod fixedly connected to the outer wall of each first gear away from the first push plate, a second connecting rod rotatably connected to the end of the first connecting rod away from the first gear, a second gear fixedly connected to the end of the second connecting rod away from the first connecting rod, a lifting plate slidably connected to the inner wall of the outer sheet, a second push plate slidably connected to one side of the lifting plate, racks fixedly connected to the outer wall of the left side near the top and the outer wall of the right side near the bottom of the second push plate, the bottom end of the left rack and the top end of the right rack of the second push plate meshing with the second gear.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-7This utility model provides a technical solution: a lightweight polyvinyl chloride composite board, including an outer board 1, a fixed frame 2 fixedly connected inside the outer board 1, a lead screw 3 rotatably connected to one side of the inner wall of the outer board 1, a movable block 4 threadedly connected to the outer wall of the lead screw 3, and a first push plate 5 fixedly connected to one side of the movable block 4. When the user rotates the lead screw 3, because the movable block 4 is threadedly connected to the lead screw 3 and limited by the inner wall of the outer board 1, the movable block 4 moves horizontally in a straight line along the axis of the lead screw 3, thereby driving the first push plate 5 to slide horizontally synchronously. A rack 6 is fixedly connected to the outer wall near the top on the left side and near the bottom on the right side of the first push plate 5. A first gear 7 is meshed between the bottom end of the left rack 6 and the top end of the right rack 6. When the first push plate 5 moves, the horizontal movement is transmitted to the first gear 7 through the rack 6, causing the first gear 7 to rotate. Each first gear 7 is fixedly connected to the outer wall on the side away from the first push plate 5. There is a first connecting rod 8. The end of the first connecting rod 8 away from the first gear 7 is rotatably connected to a second connecting rod 9. The end of the second connecting rod 9 away from the first connecting rod 8 is fixedly connected to a second gear 10. The first connecting rod 8 converts the rotational motion of the first gear 7 into an oscillating motion and transmits it to the second connecting rod 9. The second connecting rod 9 transmits the oscillating motion of the first connecting rod 8 to the second gear 10, driving the second gear 10 to rotate. The inner wall of the outer plate 1 is slidably connected to a lifting plate 12. One side of the lifting plate 12 is slidably connected to a second push plate 11. The outer wall of the second push plate 11 near the top on the left side and near the bottom on the right side are also fixedly connected to racks 6. The bottom end of the rack 6 on the left side of the second push plate 11 and the top end of the rack 6 on the right side are both meshed with the second gear 10. The second push plate 11 converts the rotational motion of the second gear 10 into a horizontal linear motion, directly pushing the lifting plate 12 to perform a vertical lifting motion. The lifting plate 12 achieves spatial separation through vertical lifting.

[0019] See Figure 1 , Figure 2 , Figure 5 , Figure 6 The front side of the outer panel 1 is fixedly connected to a protrusion 13. The protrusion 13 has slots 14 on both sides near the top and bottom. The rear side of the outer panel 1 has a sliding groove 17. The inner wall of the sliding groove 17 is slidably connected to buckles 15 on both sides near the top and bottom. The outer wall of the buckle 15 is fitted with a spring 16. When two outer panels 1 need to be spliced, the protrusion 13 of one panel is aligned with the sliding groove 17 of the other panel and pushed in. The side of the protrusion 13 contacts the arc-shaped end of the buckle 15, squeezing the buckle 15 to slide inward. At this time, the spring 16 on the outer wall of the buckle 15 is compressed. When the slot 14 on the protrusion 13 is aligned with the buckle 15, the spring 16 releases its elastic potential energy, pushing the buckle 15 outward. The arc-shaped end of the buckle 15 is inserted into the slot 14, completing the splicing and fixing of the outer panel 1. The buckles 15 on the upper and lower sides are symmetrically distributed, so that the force at the splicing point is balanced and the panels are prevented from shaking.

[0020] See Figure 6 A groove is provided on one side of the outer plate 1, and one end of the lead screw 3 extends into the groove. A hexagonal groove is provided at the end of the lead screw 3 near the groove. When it is necessary to drive the lead screw 3 to rotate, an external tool is inserted into the hexagonal groove of the lead screw 3, and rotational force is applied by the tool.

[0021] See Figure 3 , Figure 4 The outer wall of the first push plate 5 is slidably connected to the inner wall of the outer plate 1 to ensure the stability of the first push plate 5 during movement. The first push plate 5 is restricted to a fixed horizontal movement trajectory and will not shift left or right or tilt up or down due to the force during transmission, ensuring that the lifting action is continuous and smooth without jamming.

[0022] See Figure 6 The two buckles 15 have an arc-shaped end that is adjacent to each other. The arc-shaped end of the buckle 15 is adapted to the slot 14, which facilitates the quick snapping and separation between adjacent external panels 1. When the arc-shaped end of the buckle 15 contacts the protrusion 13, the arc-shaped surface can convert the thrust during splicing into a lateral component force, making it easier for the buckle 15 to be squeezed and slid into the sliding groove 17. No extra force is needed to align or press, and the splicing time of a single panel can be shortened to within a few seconds, greatly improving the operating efficiency.

[0023] See Figure 6 One end of the spring 16 is fixedly connected to the inner wall of the outer plate 1, and the other end of the spring 16 is fixedly connected to the outer wall of the buckle 15, providing elastic restoring force for the buckle 15. When adjacent plates separate, the buckle 15 is pushed back into the sliding groove 17 by the protrusion 13, at which time the spring 16 is in a compressed state. After the protrusion 13 is completely dislodged, the spring 16 immediately pushes the buckle 15 back to the initial position, so that the buckle 15 is always in the ready-to-engage state, avoiding the buckle from being stuck in the sliding groove 17 and thus failing to engage properly during the next splicing.

[0024] See Figure 1 , Figure 2 , Figure 7The outer panel 1 and the lifting panel 12 are made of lightweight polyvinyl chloride composite material, and their outer walls are smooth. The lightweight polyvinyl chloride composite material can reduce the weight of the outer panel 1 and the lifting panel 12, reduce the load pressure on the components, and extend the service life of the equipment. Polyvinyl chloride composite material has excellent waterproof and moisture-proof properties and is resistant to acid and alkali corrosion. Even in the clean and humid environment of the exhibition hall tea area and multi-functional hall, it is not easy to mold, deform or rust. At the same time, the surface is not easy to adhere to stains. With the smooth outer wall, it can be cleaned with a damp cloth every day. There is no need for regular sanding, painting or other maintenance, which reduces maintenance costs. Compared with glass, which is easy to break, and metal, which is hard and easy to be hit and injured, lightweight polyvinyl chloride composite material has good toughness and strong impact resistance. Even if it is hit by people or objects, it is not easy to break or produce sharp edges. It is especially suitable for public spaces with frequent traffic, reducing safety hazards.

[0025] Working principle: When the drive screw 3 rotates, the moving block 4 moves horizontally along the axis of the screw 3, causing the first push plate 5 to slide synchronously. The first push plate 5 rotates by meshing the first gear 7 with the rack 6. The first gear 7 drives the first connecting rod 8 to swing, and transmits power to the second gear 10 through the second connecting rod 9 to make it rotate. The second gear 10 then pushes the second push plate 11 to move horizontally by meshing with the rack 6 on the second push plate 11, and finally drives the lifting plate 12 to rise and fall vertically along the inner wall of the outer plate 1 to achieve spatial separation.

[0026] During assembly, the protrusion 13 of one board is pushed into the sliding groove 17 of another board. The protrusion 13 presses the buckle 15, causing the spring 16 to compress. When the groove 14 and the buckle 15 are aligned, the spring 16 pushes the buckle 15 into the groove 14 to complete the fixation. When separating, the operation is reversed. Furthermore, the lightweight polyvinyl chloride composite material of the outer board 1 and the lifting board 12 has the advantages of weight reduction, durability, and safety.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
