Description

Technical Field

[0001] This invention relates to the field of interior decoration building materials technology, and in particular to a quick-installation energy-saving lightweight interior partition wall panel and its assembly method. Background Technology

[0002] Interior partition wall panels are a core building material for modern architectural interior decoration and spatial functional zoning, widely used in various interior settings such as offices, residences, commercial spaces, and hotels. However, many traditional interior partition wall panels currently on the market have numerous drawbacks:

[0003] 1. Conventional wall panels have a simple structure, poor sound insulation, heat insulation and energy saving performance, and are prone to deformation, cracking and unevenness of the panel surface after long-term use, resulting in a short service life.

[0004] 2. Some lightweight wall panels have problems such as insufficient structural strength and poor wear resistance and corrosion resistance, making it difficult to balance lightweight and structural stability.

[0005] 3. Conventional indoor partition wall panels mostly adopt a fixed assembly, welding or bolt-locking installation structure. After the overall installation is completed, the structure is solidified, the formed state is uniform, and it does not have the ability to be flexibly adjusted.

[0006] Therefore, a quick-installation, energy-saving, lightweight interior partition wall panel is provided to solve the above problems. Summary of the Invention

[0007] This invention addresses the shortcomings of existing technologies by providing a quick-installation, energy-saving, lightweight indoor partition wall panel. The main body of the wall panel adopts a honeycomb lightweight core material structure. The honeycomb hollow structure significantly reduces the overall weight of the wall panel, effectively reducing the load-bearing pressure on building floors. At the same time, the honeycomb cavities form a natural sound and heat insulation layer, effectively blocking indoor and outdoor noise and reducing temperature conduction. It has excellent heat preservation, energy saving, and sound insulation and noise reduction effects. In addition, the main body of the wall panel is also equipped with connectors, which can be flexibly adjusted, effectively solving the problems mentioned in the background technology.

[0008] The technical solution adopted by the present invention to solve the above problems is as follows:

[0009] A quick-installation, energy-saving, lightweight interior partition wall panel includes a main panel, which is an integrated prefabricated sandwich composite structure. The sandwich composite structure includes a core material, a panel attached to the front of the core material, and a back panel attached to the back of the core material. The core material is a lightweight honeycomb hollow structure. The panel is a galvanized steel sheet with a spray-coated film structure. The back panel is a roller-coated sheet. The panel, core material, and back panel are bonded together using an environmentally friendly special adhesive through a high-pressure hot-pressing process, resulting in a tight interlayer bond. The upper end of the main panel is equipped with a connector, which includes a hanging rail and a hanging plate. The main panel is installed at the lower end of the hanging plate, and the hanging plate can slide and rotate at the lower end of the hanging rail.

[0010] The hanging plate is equipped with a positioning component, which includes a rotatable handle, a locking gear at the upper end of the hanging plate, and a locking block on one side of the hanging plate. When the handle is turned, the locking gear can move upward, the locking block can move to one side and rotate.

[0011] A sleeve is fixedly connected to the upper end of the hanging plate, and a square slider is rotatably connected to the outer surface of the sleeve. The square slider is slidably connected to the inner wall of the hanging rail.

[0012] The inner wall of the sleeve is provided with an inner shaft that can move up and down. The locking gear is fixed to the upper end of the outer surface of the inner shaft. The inner wall of the hanging rail is fixed with two locking racks that cooperate with the locking gear.

[0013] The inner wall of the hanging plate is provided with a movable guide seat, and a sliding pin is fixedly connected to the lower end of the inner shaft. The inner wall of the guide seat is provided with a slanted keyway that cooperates with the sliding pin. One end of the guide seat is provided with a rotatable long shaft. A locking block is fixedly connected to one end face of the long shaft. The inner wall of the hanging plate is provided with a locking groove that cooperates with the locking block.

[0014] The inner wall of the hanging plate is also provided with a rotatable drive cylinder. A cam is fixedly connected to the outer surface of the drive cylinder, and a long pin is fixedly connected to the lower end of the guide seat. A short arc groove, an arc-shaped inclined groove, and a long arc groove are opened on the outer surface of the cam to cooperate with the long pin.

[0015] A first pulley is fixedly connected to one side of the outer surface of the drive cylinder, a connecting cylinder is rotatably connected to the inner wall of the hanging plate, a second pulley is fixedly connected to the outer surface of the connecting cylinder, the first pulley and the second pulley are connected by a belt, a spline tooth is provided on the outer surface of the long shaft, and a spline groove that mates with the spline tooth is opened on the inner wall of the connecting cylinder.

[0016] A cross groove is provided on one end face of the handle, and a drive shaft is fixedly connected to the other end of the handle. The drive shaft is slidably connected to the inner wall of the drive cylinder. A convex key is provided on the inner wall of the hanging plate, and a missing key groove that matches the convex key is provided on the outer surface of the handle.

[0017] A retaining pad is rotatably connected to the outer surface of the drive shaft, and a spring that cooperates with the retaining pad is also fitted on the outer surface of the drive shaft.

[0018] An assembly method for a quick-installation energy-saving lightweight interior partition wall panel includes the following steps:

[0019] S1. Precast integral main panel: It adopts lightweight honeycomb hollow structure core material, galvanized steel plate spray coating panel, and roller coated back panel. It uses environmentally friendly special adhesive and high pressure hot pressing process to composite and solidify the three into an integrated sandwich composite structure main panel.

[0020] S2. Assemble the sliding and rotating connecting parts: Assemble the connecting parts consisting of the hanging rail and the hanging plate at the upper end of the main body plate, and integrate the pre-installed positioning components inside the hanging plate; realize the sliding and rotating cooperation between the hanging plate and the hanging rail through the sleeve and the square slider, assemble the locking rack inside the hanging rail, and assemble the inner shaft with the locking gear inside the hanging plate through the spline sliding assembly.

[0021] S3. Assembly linkage locking structure: A guide seat with a slanted keyway and a long shaft with a locking block are assembled inside the hanging plate. The guide seat and the lower end sliding pin of the inner shaft are linked and engaged. A drive cylinder with a cam is assembled inside the hanging plate. The guide seat reciprocates and slides through the engagement of the cam and the lower end long pin of the guide seat.

[0022] S4. Assembly handle limiting structure: The handle with cross groove is connected to the drive cylinder through the drive shaft spline. A retaining washer and a return spring are installed on the outside of the drive shaft. The handle is limited in normal state by using the keyway notch of the handle and the convex keyway of the hanging plate.

[0023] S5. On-site hoisting and positioning: Fix the hoisting rail to the indoor ceiling, and fix the assembled main body panel to the lower end of the hoisting plate to complete the overall hoisting and pre-installation of the wall panel;

[0024] S6. Wall panel unfolding and locking: Press and turn the handle to drive the cam to slide the guide seat. On the one hand, it drives the inner shaft and locking gear to move upward and engage with the locking rack to lock the position of the hanging panel. On the other hand, it drives the locking block to insert into the locking groove of the adjacent hanging panel. At the same time, the locking block is driven to rotate and lock through the belt pulley drive, so as to realize the integrated fixed unfolding of multiple wall panels.

[0025] S7. Wall panel storage and reset: Rotate the handle in the opposite direction to reset all the structures in linkage, so that the locking gear and locking block are unlocked synchronously, releasing the overall locking of the wall panel, and the wall panel can be slid and rotated to the vertical storage state.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] During use, the matching hanging rail is fixed to the indoor ceiling. The wall panel body slides along the hanging rail via a top hanging plate and a square slider. Relying on the rotational structure of the sleeve and the square slider, the wall panel can move left and right along the hanging rail, while also supporting overall rotation and swing, achieving flexible positioning and retraction adjustment to adapt to different indoor layout renovation needs. For daily use and adjustment, the operator can use a special tool to connect to the cross groove of the wall panel handle. After pressing the handle to release the limit lock, rotating the handle will drive the internal drive cylinder, cam, and belt drive structure to operate synchronously. On one hand, the cam linkage guides the seat to move, driving the inner shaft and locking gear to move upward, so that the locking gear and the inner locking rack of the hanging rail are precisely engaged. The system precisely engages, positioning and limiting individual wall panels to prevent displacement and loosening. Simultaneously, it drives the long shaft and locking block to extend laterally, inserting the locking block into the locking groove of adjacent wall panels. Through spline transmission, the locking block rotates and misaligns, achieving interlocking and fixing multiple wall panels. This allows the unfolded panels to form a unified, tightly fitted, and secure partition structure. When adjusting interior space, merging zones, or expanding storage, simply rotate the handle in the opposite direction to disengage the locking gears and lock block, unlocking the wall panels. The panels can then be freely moved and rotated, folded, and returned to their original positions, quickly completing spatial layout modifications. After operation, the handle automatically resets and locks under spring action, effectively preventing structural misoperation and ensuring safety. The overall wall panel adopts a honeycomb lightweight sandwich composite structure, integrally formed by high-pressure hot pressing, resulting in a tight and stable interlayer bond that is not prone to delamination and cracking. It is lightweight and does not increase the load on the building floor, making it suitable for low-load-bearing scenarios such as old buildings and light steel structures, as well as various indoor scenarios such as offices, residences, shopping malls, and hotels. The honeycomb hollow structure has excellent sound and heat insulation performance, effectively blocking noise and reducing heat conduction. Combined with an integrated sealing structure, it avoids the problems of air leakage and heat transfer from traditional wall panel gaps, resulting in outstanding energy-saving and noise-reducing effects. Featuring a galvanized steel sheet with a spray-coated film design, this product is wear-resistant, rust-proof, aesthetically pleasing, and scratch-resistant. The back panel offers excellent protection, and the overall structure boasts high strength and resistance to deformation, completely resolving the drawbacks of traditional wall panels such as loosening, shaking, deformation, and cracking, significantly extending its service life. Furthermore, its quick-installation structure eliminates the need for complex tools and cumbersome procedures, making installation convenient and quick. It is also repeatedly adjustable and reusable, eliminating the need to remove or replace wall panels during space renovations, effectively reducing material waste and significantly lowering labor and material costs for interior decoration, layout modifications, and subsequent maintenance. Balancing structural stability, spatial flexibility, energy efficiency, practicality, and cost-effectiveness, it offers exceptional overall value. Attached Figure Description

Detailed Implementation

[0036] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0037] like Figures 1-7 As shown, this invention provides a quick-installation energy-saving lightweight interior partition wall panel, including a main panel 1. The main panel 1 is an integrated prefabricated sandwich composite structure, which includes a core material, a panel attached and fixed to the front of the core material, and a back panel attached and fixed to the back of the core material. The core material is a lightweight honeycomb hollow structure. The panel is a galvanized steel sheet with a spray-coated film structure. The back panel is a roller-coated sheet. The panel, core material, and back panel are bonded together using an environmentally friendly special adhesive and cured into a single unit through a high-pressure hot-pressing process, resulting in a tight interlayer bond. The upper end of the main panel 1 is provided with a connector, which includes a hanging rail 3 and a hanging plate 2. The main panel 1 is installed at the lower end of the hanging plate 2, and the hanging plate 2 can slide and rotate at the lower end of the hanging rail 3.

[0038] like Figures 1-5As shown, the wall panel utilizes a honeycomb-shaped lightweight modified core material. The honeycomb hollow structure significantly reduces the overall weight of the wall panel, effectively alleviating the load-bearing pressure on building floors and making it suitable for various old buildings, light steel structures, and other low-load-bearing scenarios. Simultaneously, the honeycomb cavities form a natural sound and heat insulation layer, effectively blocking indoor and outdoor noise and reducing temperature conduction, resulting in excellent thermal insulation, energy saving, and sound insulation and noise reduction effects. The honeycomb core material has excellent structural mechanical properties, evenly distributing loads and effectively preventing bending, deformation, and cracking of the wall panel over long-term use. Combined with a galvanized steel sheet with a spray-coated panel, the overall structure boasts high strength and rigidity, is wear-resistant, rust-proof, and scratch-resistant, significantly extending its service life. The front-coated steel sheet has a smooth surface. It is aesthetically pleasing and has a good decorative effect. The roller-coated back panel has excellent adhesion and strong protection. The three-layer composite structure combines lightweight, structural strength, energy saving, sound insulation, decoration and protection, making it widely applicable to various indoor space partitioning scenarios such as offices, residences, shopping malls, and hotels. It is used in a wide range of applications. It is composite and cured into one piece through a high-pressure hot-pressing process, with tight interlayer bonding, no loosening or gaps, and excellent overall structural stability, making it less prone to delamination and cracking. Through the set connecting parts, namely the hanging rail 3 and the hanging plate 2, the main plate 1 is fixed to the lower end of the hanging plate 2, and the hanging rail 3 is fixed to the ceiling. The hanging plate 2 can slide and rotate at the lower end of the hanging rail 3, which can be flexibly adjusted according to needs.

[0039] The hanging plate 2 is equipped with a positioning component, which includes a rotatable handle 4. The upper end of the hanging plate 2 is equipped with a locking gear 21, and a locking block 31 is equipped on one side of the hanging plate 2. When the handle 4 is rotated, the locking gear 21 can move upward and the locking block 31 can move to one side and rotate.

[0040] like Figures 2-4 As shown, existing fixed partition wall panels cannot be rotated or moved after construction, and can only permanently divide fixed areas, making it difficult to adapt to the current multifunctional and dynamic use needs of interior spaces. In daily use scenarios, when users need to adjust the size of the interior space, merge partitions, change the layout, or temporarily expand the space, traditional wall panels can only be modified by disassembling the whole, re-cutting, and reinstalling. This is not only cumbersome and time-consuming, but also prone to damage to the wall panels and waste of materials, significantly increasing the cost of space renovation and maintenance. At the same time, traditional spliced ​​partition wall panels rely on simple splicing structures, resulting in poor overall connection stability. The splicing gaps are prone to loosening and misalignment, and the sound insulation and heat insulation energy-saving effects are not good. The overall structural integrity cannot be guaranteed, and long-term use is prone to deformation and shaking. It is difficult to meet the multiple use needs of space flexibility, structural stability, and energy-saving practicality. The industry urgently needs a new type of lightweight partition wall panel that can be flexibly retracted, easy to install, and has overall stability.

[0041] By using the positioning components, namely the locking gear 21 and the locking block 31, when the locking gear 21 moves upward, it can mesh with the locking rack 22, thereby limiting and fixing the hanging plate 2. That is, the hanging plate 2 will not move at the lower end of the hanging rail 3. The locking block 31 can be inserted into the adjacent locking groove 32 when it moves to one side. When the locking block 31 rotates, it can be misaligned with the locking groove 32. At this time, multiple partition wall panels can be fixed as a whole, which is the unfolded state.

[0042] This wall panel abandons the traditional fixed installation structure, featuring rotation and translation functions. It can freely switch between fully unfolded and folded states according to the needs of different interior scenarios. Without disassembling and reconstructing the wall panel structure, it can quickly complete layout adjustments such as interior space partitioning, expansion, and merging, perfectly adapting to the dynamic space usage needs of offices, commercial spaces, and homes, significantly improving interior space utilization and scenario adaptability. When the wall panel is fully unfolded, multiple partitioned wall panels can be quickly locked into a single integrated structure using a dedicated positioning component, effectively solving the problems of loose gaps, insecure splicing, and easy shaking and deformation of traditional spliced ​​wall panels. The precise positioning structure provides stable fixation, significantly improving the overall load-bearing capacity and deformation resistance of the wall panel, ensuring long-term use. The product boasts superior structural stability and enhanced safety during installation. Its quick-installation design, combined with lightweight substrate, eliminates the need for complex tools and cumbersome procedures, making installation, adjustment, and storage simple and convenient, effectively shortening the construction cycle. Furthermore, it is reusable and adjustable, eliminating the need to remove or replace wall panels during space modifications, thus avoiding material waste and significantly reducing labor and material costs associated with interior space layout modifications and maintenance. The lightweight design of the wall panels minimizes their weight and load, placing no additional burden on the building's floor slab and making them suitable for most interior decoration scenarios. Simultaneously, the integrated, stable structure effectively optimizes the wall panel's sealing performance, reducing air leakage and heat transfer issues, improving indoor sound and heat insulation, achieving energy conservation and consumption reduction, and balancing practicality and energy efficiency for higher overall value.

[0043] A sleeve 19 is fixedly connected to the upper end of the hanging plate 2. A square slider 18 is rotatably connected to the outer surface of the sleeve 19. The square slider 18 is slidably connected to the inner wall of the hanging rail 3.

[0044] like Figures 2-5 As shown, the square slider 18 can slide left and right on the inner wall of the hanging rail 3, so that the hanging plate 2 can move left and right at the lower end of the hanging rail 3. It is rotatably connected to the square slider 18 through the sleeve 19, so that the hanging plate 2 can also rotate at the lower end of the hanging rail 3, that is, it can rotate to the vertical state to retract.

[0045] The inner wall of the sleeve 19 is provided with an inner shaft 20 that can move up and down. The locking gear 21 is fixedly connected to the upper end of the outer surface of the inner shaft 20. The inner wall of the hanging rail 3 is fixedly connected with two locking racks 22 that cooperate with the locking gear 21.

[0046] like Figure 3 and Figure 6 As shown, the inner shaft 20 and the sleeve 19 are connected by a spline. The inner shaft 20 can slide up and down on the inner wall of the sleeve 19. When the inner shaft 20 does not rotate, it can restrict the rotation of the sleeve 19, the hanging plate 2, the main plate 1, etc. When the inner shaft 20 and the locking gear 21 are in the lowest position, they can be misaligned with the locking rack 22. That is, at this time, the locking gear 21 will not mesh with the locking rack 22, and the square slider 18, the hanging plate 2, etc. can move left and right. When the inner shaft 20 and the locking gear 21 move upward and mesh with the locking rack 22, it can restrict the left and right movement and rotation of the locking gear 21 and the inner shaft 20, thereby fixing the position of the hanging plate 2 and the main plate 1.

[0047] The inner wall of the hanging plate 2 is provided with a movable guide seat 17, and the lower end of the inner shaft 20 is fixedly connected to a sliding pin 23. The inner wall of the guide seat 17 is provided with a slanted keyway 24 that cooperates with the sliding pin 23. One end of the guide seat 17 is provided with a rotatable long shaft 25. The locking block 31 is fixedly connected to one end face of the long shaft 25. The inner wall of the hanging plate 2 is provided with a locking groove 32 that cooperates with the locking block 31.

[0048] like Figures 4-6 As shown, the guide seat 17 and the long shaft 25 can slide left and right on the inner wall of the hanging plate 2. The long shaft 25 is rotatably connected to the inner wall of the guide seat 17. When the guide seat 17 moves left and right, it can drive the long shaft 25 and the locking block 31 to move left and right, and the long shaft 25 can also rotate, that is, drive the locking block 31 to rotate; the installation and shape of the guide seat 17 and the sliding pin 23 are as follows. Figure 6 As shown, when the guide seat 17 moves to the right, the inner shaft 20 and the locking gear 21 can be driven to move upward through the cooperation of the inclined keyway 24 and the sliding pin 23. That is, the locking gear 21 moves upward to mesh with the locking rack 22, thus fixing the position of the hanging plate 2. At the same time, when the guide seat 17 moves to the right, it can also drive the long shaft 25 and the locking block 31 to move to the right synchronously. When the locking block 31 moves to the right, it can be inserted into the locking groove 32 of the adjacent hanging plate 2. The shape of the locking groove 32 is as follows. Figure 4 As shown, when the locking block 31 is inserted into the locking groove 32, the long shaft 25 rotates, which can cause the locking block 31 to rotate and misalign with the outlet of the locking groove 32. In other words, it can prevent the locking block 31 from separating from the locking groove 32, thus enabling the integral fixing of multiple partition wall panels.

[0049] The inner wall of the hanging plate 2 is also provided with a rotatable drive cylinder 11. A cam 12 is fixedly connected to the outer surface of the drive cylinder 11. A long pin 13 is fixedly connected to the lower end of the guide seat 17. A short arc groove 14, an arc-shaped inclined groove 15 and a long arc groove 16 that cooperate with the long pin 13 are opened on the outer surface of the cam 12.

[0050] like Figures 6-7As shown, a support seat is fixed to the outer surface of the long pin 13, and the support seat is fixed to the inner wall of the guide seat 17, which is equivalent to the long pin 13 being fixed to the lower end of the guide seat 17; the drive cylinder 11 is rotatably connected to the inner wall of the hanging plate 2, and when the drive cylinder 11 rotates, it can drive the cam 12 to rotate. The installation and shape of the cam 12 and the long pin 13 are as follows. Figure 7 As shown, when the long pin 13 engages with the short arc groove 14, the position of the long pin 13 can be locked, so that the long pin 13, guide seat 17, long shaft 25, locking block 31, etc. are in the leftmost locked position, that is, the corresponding locking gear 21 is in the bottom stable position and the locking block 31 is stable inside the hanging plate 2; similarly, when the long pin 13 engages with the long arc groove 16, the long pin 13, guide seat 17, long shaft 25, locking block 31, etc. can be in the rightmost locked position, that is, the corresponding locking gear 21 can be in the top stable position and stably engage with the locking rack 22, and the locking block 31 is in the right position, that is, stable inside the locking groove 32, and will not disengage from the locking groove 32; when the drive cylinder 11, cam When cam 12 rotates in the forward direction, it allows the long pin 13 to slide from the inner wall of the short arc groove 14 into the inner wall of the arc-shaped inclined groove 15. When the drive cylinder 11 and cam 12 continue to rotate, they allow the long pin 13, guide seat 17, long shaft 25, locking block 31, etc. to move to the right. When cam 12 rotates to the point where the long pin 13 enters the inner wall of the long arc groove 16, the long pin 13, guide seat 17, long shaft 25, locking block 31, etc. move to the top position to the right and no longer move to the right. When the drive cylinder 11 and cam 12 continue to rotate, they no longer drive the long pin 13, locking block 31, etc. to move to the right. When the drive cylinder 11 and cam 12 rotate in the reverse direction, they allow the long pin 13, long shaft 25, etc. to move to the left and reset to the initial state.

[0051] A first pulley 29 is fixedly connected to one side of the outer surface of the drive cylinder 11. A connecting cylinder 27 is rotatably connected to the inner wall of the hanging plate 2. A second pulley 30 is fixedly connected to the outer surface of the connecting cylinder 27. The first pulley 29 and the second pulley 30 are connected by a belt. A spline tooth 26 is provided on the outer surface of the long shaft 25. A spline groove 28 that mates with the spline tooth 26 is provided on the inner wall of the connecting cylinder 27.

[0052] like Figure 6As shown, when the drive cylinder 11 rotates, it can drive the first pulley 29, the second pulley 30, and the connecting cylinder 27 to rotate synchronously. Through the provided spline teeth 26 and spline groove 28, when the long pin 13 and long shaft 25 move to the right, causing the spline teeth 26 to insert into the inner wall of the spline groove 28, the drive cylinder 11 and connecting cylinder 27, when rotating, can drive the spline teeth 26, long shaft 25, and locking block 31 to rotate synchronously, even if the locking block 31 moves to the right into the locking groove 32 and then rotates out of position. Through the mutual cooperation of the cam 12 and the long pin 13, and the spline teeth 26 and spline groove 28, when the drive cylinder 11, cam 12, and first pulley 29 rotate synchronously in the forward direction, the engagement of the cam 12 and the long pin 13 allows the long pin 13 to slide from the short arc groove 14 into the arc-shaped groove. When the long pin 13 slides into the inner wall of the long arc groove 16, the long pin 13, long shaft 25, locking block 31, etc. can move to the top position to the right, that is, the locking block 31 enters the inner wall of the locking groove 32, that is, the spline tooth 26 is inserted into the inner wall of the spline groove 28. At this time, when the drive cylinder 11, cam 12, first pulley 29, second pulley 30, connecting cylinder 27, etc. continue to rotate, they can drive the long shaft 25, locking block 31, etc. to rotate. Even if the locking block 31 is misaligned with the locking groove 32, it prevents the locking block 31 from disengaging from the locking groove 32. When the drive cylinder 11, cam 12, etc. rotate in the opposite direction, the locking block 31 can be rotated back to the horizontal state, that is, it can disengage from the locking groove 32. At this time, the long pin 13, long shaft 25, etc. will move to the initial state to the left.

[0053] A cross groove 5 is provided on one end face of the handle 4, and a drive shaft 8 is fixedly connected to the other end of the handle 4. The drive shaft 8 is slidably connected to the inner wall of the drive cylinder 11. A protruding keyway 7 is provided on the inner wall of the hanging plate 2, and a missing keyway 6 that matches the protruding keyway 7 is provided on the outer surface of the handle 4.

[0054] like Figure 4 As shown, the drive shaft 8 and the drive cylinder 11 are connected by a spline. The drive shaft 8 can slide left and right on the inner wall of the drive cylinder 11, and when the drive shaft 8 rotates, it can cause the drive cylinder 11 to rotate. The handle 4 facilitates the control of the rotation of the drive shaft 8 and the drive cylinder 11. The keyway 6 and the keyway 7 restrict the handle 4 when they are engaged, thus preventing the handle 4, drive shaft 8, and drive cylinder 11 from rotating accidentally. In use, by inserting the cross handle into the cross groove 5 and pressing the handle 4 to move it to the right, the handle 4 is disengaged from the keyway 7. At this time, rotating the cross handle will drive the handle 4, drive shaft 8, and drive cylinder 11 to rotate.

[0055] A retaining pad 9 is rotatably connected to the outer surface of the drive shaft 8, and a spring 10 that cooperates with the retaining pad 9 is also fitted on the outer surface of the drive shaft 8.

[0056] like Figure 4As shown, the baffle 9 can slide left and right on the inner wall of the hanging plate 2. One end of the spring 10 is fixed to the baffle 9, and the other end of the spring 10 is fixed to the inner wall of the hanging plate 2. The spring 10 always exerts a leftward driving force on the baffle 9 and the drive shaft 8. Even if the drive shaft 8 and the handle 4 are in the leftmost position under normal conditions, that is, under normal conditions, the keyway 6 and the convex keyway 7 are stably engaged, limiting the rotation of the handle 4, the drive cylinder 11, the cam 12, etc.

[0057] An assembly method for a quick-installation energy-saving lightweight interior partition wall panel includes the following steps:

[0058] S1. Precast integral main body panel 1: The main body panel 1 is made of lightweight honeycomb hollow structure core material, galvanized steel sheet spray-coated panel, and roller-coated back panel. The three are combined and cured into an integrated sandwich composite structure using environmentally friendly special adhesive and high-pressure hot pressing process.

[0059] S2. Assemble the sliding and rotating connecting parts: Assemble the connecting parts consisting of the hanging rail 3 and the hanging plate 2 on the upper end of the main plate 1. Integrate the pre-installed positioning components inside the hanging plate 2. The sliding and rotating cooperation between the hanging plate 2 and the hanging rail 3 is realized through the sleeve 19 and the square slider 18. The locking rack 22 is assembled on the inner side of the hanging rail 3. The inner shaft 20 with the locking gear 21 is slidably assembled inside the hanging plate 2 through the spline.

[0060] S3. Assembly linkage locking structure: A guide seat 17 with a slanted keyway 24 and a long shaft 25 with a locking block 31 are assembled in the hanging plate 2. The guide seat 17 is linked with the sliding pin 23 at the lower end of the inner shaft 20. A drive cylinder 11 with a cam 12 is assembled in the hanging plate 2. The guide seat 17 reciprocates and slides through the cooperation of the cam 12 with the long pin 13 at the lower end of the guide seat 17.

[0061] S4. Assembly handle 4 limiting structure: The handle 4 with cross groove 5 is connected to the drive cylinder 11 through the drive shaft 8 spline. The retaining pad 9 and the return spring 10 are assembled on the outside of the drive shaft 8. The handle 4 with missing keyway 6 and the hanging plate 2 with protruding keyway 7 are used to limit the handle 4 in normal state.

[0062] S5. On-site hoisting and positioning: Fix the hoisting rail 3 to the indoor ceiling, and fix the assembled main body panel 1 to the lower end of the hoisting plate 2 to complete the overall hoisting and pre-installation of the wall panel;

[0063] S6. Wall panel unfolding and locking: Press and rotate handle 4 to drive cam 12 to drive guide seat 17 to slide. On the one hand, it drives inner shaft 20 and locking gear 21 to move upward and mesh with locking rack 22 to lock the position of hanging plate 2. On the other hand, it drives locking block 31 to insert into the locking groove 32 of adjacent hanging plate 2. At the same time, it drives locking block 31 to rotate and misalign and lock through belt drive to realize the integrated fixed unfolding of multiple wall panels.

[0064] S7. Wall panel storage reset: Rotate handle 4 in the opposite direction to reset all structures, so that locking gear 21 and locking block 31 are unlocked simultaneously, releasing the overall locking of the wall panel, and the wall panel can be slid and rotated to the vertical storage state.

[0065] In use, the matching hanging rail 3 is fixed to the indoor ceiling. The wall panel body slides with the hanging rail 3 through the top hanging plate 2 and the square slider 18. Relying on the rotation structure of the sleeve 19 and the square slider 18, the wall panel can move left and right along the hanging rail 3, while supporting overall rotation and swing, realizing flexible movement and retraction adjustment to adapt to different indoor layout renovation needs. During daily use and adjustment, the staff can use a special tool to connect to the cross groove 5 of the wall panel handle 4, press the handle 4 to release the limit lock, and then rotate the handle 4 to drive the internal drive cylinder 11, cam 12, and belt drive structure to operate synchronously. On the one hand, the cam 12 drives the guide seat 17 to move, driving the inner shaft 20 and the locking gear 21 upward. The movement allows the locking gear 21 to precisely mesh with the inner locking rack 22 of the hanging rail 3, completing the positioning and limiting of a single wall panel and preventing displacement and loosening. Simultaneously, it drives the long shaft 25 and locking block 31 to extend laterally, allowing the locking block 31 to insert into the locking groove 32 of the adjacent wall panel. Through spline transmission, the locking block 31 rotates and shifts, achieving interlocking and fixing between multiple wall panels. This allows the multiple wall panels to form an integrated, tightly joined, and secure partition structure. When it is necessary to adjust the interior space, merge partitions, or expand storage, simply rotate the handle 4 in the opposite direction to release the locking gear 21 from meshing and the locking block 31 from shifting, unlocking the wall panel's limiting state. The wall panel can then be freely moved and rotated. The wall panels rotate, fold, and return to their original positions, quickly completing spatial layout modifications. After operation, handle 4 automatically resets and locks under the action of spring 10, effectively preventing accidental structural movement and ensuring safety. The overall wall panel adopts a honeycomb lightweight sandwich composite structure, integrally formed through a high-pressure hot-pressing process. The interlayer bonding is tight and stable, not prone to delamination and cracking. It is lightweight and does not increase the load on the building floor, making it suitable for low-load-bearing scenarios such as old buildings and light steel structures, as well as various indoor scenarios such as offices, residences, shopping malls, and hotels. The honeycomb hollow structure has excellent sound and heat insulation performance, effectively blocking noise and reducing heat conduction. Combined with the integrated sealing structure, it avoids the problems of air leakage and heat transfer caused by gaps in traditional wall panels. The product boasts outstanding energy-saving and noise-reduction effects. The wall panel features a galvanized steel sheet with a spray-coated finish, making it wear-resistant, rust-proof, aesthetically pleasing, and scratch-resistant. The back panel offers excellent protection, and the overall structure is strong and resistant to deformation, completely solving the problems of traditional wall panels being prone to loosening, shaking, deformation, and cracking, significantly extending its service life. Furthermore, the product features a quick-installation structure, requiring no complex tools or cumbersome procedures for construction. Installation is convenient, the construction period is short, and it can be repeatedly adjusted and reused. Space renovations do not require the removal and replacement of wall panels, effectively reducing material waste and significantly lowering the labor and material costs for interior decoration, layout modifications, and subsequent maintenance. It balances structural stability, spatial flexibility, energy efficiency, practicality, and economic applicability, resulting in extremely high overall value.
