Description

Technical Field

[0001] This invention relates to the field of polyurethane-sealed rock wool sandwich panels, specifically to a polyurethane-sealed rock wool sandwich panel. Background Technology

[0002] Rock wool sandwich panels are sandwich panels made of rock wool, fully utilizing the unique properties of the rock wool core material. By combining the rock wool core material with a polyurethane foam interlayer, excellent thermal insulation and weather resistance are achieved. This technology includes key steps such as sandwich panel preparation, edge sealing, cutting and shaping, and external surface coating to ensure that the sandwich panels provide reliable thermal insulation and structural support after installation, while also possessing aesthetic and durable appearance characteristics, making them suitable for various building applications.

[0003] Polyurethane-sealed rock wool sandwich panels are a widely used thermal insulation material in the construction industry. During installation, nails are typically used to fix the sandwich panels to the supporting structure; however, this fixing method easily damages both the sandwich panels and the nails, making disassembly difficult. Nailing the sandwich panels penetrates the insulation layer, leading to decreased insulation performance and increased heat conduction, thus weakening the insulation effect. Furthermore, the use of nails can damage the structure of the sandwich panels, especially if used improperly or excessively, causing them to detach, deform, or crack. It also affects the moisture-proof performance of the sandwich panels, leading to moisture penetration problems. Once sandwich panels are fixed with nails, they are generally difficult to disassemble and reuse, and disassembly will damage both the sandwich panels and nails, making them unsuitable for reuse. Over time, the nails will be affected by oxidation, corrosion, or other environmental factors, leading to decreased stability and requiring regular inspection and maintenance. Using nails extensively on sandwich panels weakens their structural stability, making them more susceptible to wind, rain, snow, or other external environmental factors. In addition, nailing can damage the outer surface coating of the sandwich panel, thus affecting its aesthetics.

[0004] In view of the above, in order to overcome the above technical problems, the present invention designs a polyurethane-sealed rock wool sandwich panel, which solves the above technical problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that improper or excessive use of nails will damage the structure of the sandwich panel, and it is particularly easy to cause the sandwich panel to fall off, deform or break; using nails to fix the sandwich panel makes it difficult to disassemble and reuse it, and disassembly will cause damage to the sandwich panel and nails, and it is not suitable for reuse.

[0006] To address the above problems, the present invention provides the following technical solution:

[0007] A polyurethane edge-sealed rock wool sandwich panel provided by the present invention includes a plate body, and also includes a locking mechanism and an adjusting mechanism. The locking mechanism is installed on one side of the plate body, and the adjusting mechanism is installed on the other side of the plate body. The displacement of the locking mechanism expanding outward through the fixed rod is converted into the horizontal displacement of the sliding cylinder and then into the extrusion of the partition board by the rotating rod, so as to clamp and fix the partition board and the baffle. The adjusting mechanism converts the force pulled by the adjusting rope into the rotational force of the rotating cylinder, and the rotating rotating cylinder squeezes the fixed rod in the locking mechanism, making the side surface of the fixed rod and the fixed cylinder consistent, so as to realize the separation between the partition board and the baffle.

[0008] The combined design of the locking mechanism and the adjusting mechanism is adopted to ensure the height fixation between the two plate bodies. The locking mechanism clamps the partition board and the baffle through the coordinated action of the sliding cylinder and the rotating rod, preventing loosening and shaking between them, thereby improving the stability between the plate bodies. Through the adjusting mechanism, the separation distance between the plate bodies can be easily adjusted. The force of the adjusting rope is converted into the rotational force of the rotating cylinder, making the side surface of the fixed rod in the locking mechanism and the fixed cylinder consistent, thus realizing the separation between the partition board and the baffle. This makes the installation and maintenance of the plate body more flexible and convenient. Through the interaction between the locking mechanism and the adjusting mechanism, it can be ensured that the clamping between the edge-sealed plates is very firm, thereby improving the overall stability and strength of the plate body. The design of the fixed cylinder and the fixed rod makes the locking mechanism have good stability and can maintain the clamping state of the plate under the action of vibration or external forces.

[0009] The locking mechanism includes a partition board, a fixed cylinder, a sliding groove, a sliding cylinder, a compression spring, a concave groove, a fixed rod, a sliding ball and a rotating rod. The partition board is fixedly installed on the side of the plate body. A stable groove is provided on the partition board. The fixed cylinder is fixedly installed on the side of the partition board. The cross-sectional shape of the front end of the fixed cylinder is an isosceles trapezoid. The isosceles trapezoid fixed cylinder has a larger contact area when installed with the adjusting mechanism, thus improving the stability between the fixed cylinder and the adjusting mechanism. A sliding groove is provided inside the fixed cylinder, and a sliding cylinder is slidably installed inside the sliding groove. The cross-sectional shape of both ends of the sliding cylinder is "soil" shape. The "soil" shape sliding cylinder has a larger side contact area, improving the contact between both ends of the sliding cylinder and the inner surface of the fixed groove, providing more friction force, thereby increasing the clamping force. The front end of the "soil" shape sliding cylinder is clamped with a compression spring. Concave grooves are provided at both ends of the side surface of the fixed cylinder. The left end of the concave groove is rotatably installed with a fixed rod. A sliding ball is slidably installed at the front end of the fixed rod. The right end of the groove is rotatably installed with a rotating rod.

[0010] Through the coordinated action of components such as the partition, fixed cylinder, and sliding groove, the locking mechanism ensures stable fixation between the partition and the baffle. The sliding cylinder, with its "V"-shaped cross-section and compression spring design, provides stability during sliding, effectively preventing shaking and loosening of internal parts. This also contributes to a more compact component layout and improved overall performance. The compression spring provides additional compressive force, enhancing the clamping effect between the plates and improving the overall stability and strength of the plate. The fixed cylinder's front end has an isosceles trapezoidal cross-section, reducing friction during installation and allowing for quick positioning, thus reducing installation complexity and time and improving production efficiency. The locking mechanism design ensures the stability and compactness of the internal components. The coordinated action of components such as the sliding cylinder, fixed rod, and sliding ball ensures they are not easily affected by external impacts or vibrations during use, extending component lifespan. The fixed rod is installed within the "U"-shaped fixed groove, ensuring stable positioning within a certain range and achieving stability of the locking mechanism. Meanwhile, the concave fixing groove can effectively fix the fixing rod, reducing the risk of the fixing rod falling off or moving due to external impact or vibration, and improving the safety of the locking mechanism.

[0011] The cross-sectional shape of the fixing rod is "L". The short side of the "L"-shaped fixing rod slides on the groove of the "E"-shaped sliding cylinder. The "L"-shaped fixing rod and the "E"-shaped sliding cylinder cooperate to make the connection of the fixing rod in the groove of the sliding cylinder firm. A limit groove is opened on the side of the fixing cylinder.

[0012] The fixed rod has an "L"-shaped cross-section, with its short side sliding between the "E"-shaped sliding cylinders, providing additional stability. During sliding, the "L"-shaped fixed rod rotates stably, ensuring a secure lock and clamping of the plates. Furthermore, the triangular shape at the front end of the fixed rod provides a larger contact area during compression, allowing the fixed rod to be more stably compressed by the adjusting mechanism, improving the efficiency of pressure transmission and ensuring the stability of the plates under different conditions. Limiting grooves are provided on the sides of the fixed cylinders, further enhancing control. These grooves limit the range of motion of the fixed rod, ensuring precise positioning and secure fixing between the plates when needed. Additionally, the interaction between the fixed rod and the sliding cylinders reduces friction and energy loss, making the locking mechanism more efficient. This design improvement enhances the overall system performance and stability.

[0013] The cross-sectional shape of the limiting groove is convex, and the upper end of the convex limiting groove is arc-shaped. The sliding ball and the limiting groove are interference-fitted, which enables the sliding ball to slide between the fixed rods, reduces the friction between the sliding ball and the fixed rods, and plays a stabilizing role for the sliding cylinder during the sliding process.

[0014] The combination of a convex-shaped limiting groove and a superior arc-shaped upper end achieves an interference fit between the sliding ball and the limiting groove, helping to reduce friction between the sliding ball and the fixed rod, thus improving the stability and performance of the entire locking mechanism. Less friction extends the service life of components, and the interference fit and stable interaction between the sliding ball and the limiting groove ensure the sliding cylinder remains stable during sliding. This stability is crucial for ensuring the position of internal components does not change, especially under vibration or impact conditions. The superior arc-shaped upper end and the interference fit design provide more precise position control. Reduced friction and improved stability mean that the locking mechanism components experience less wear and damage, thus requiring less maintenance. This helps reduce maintenance costs and downtime. The limiting groove also allows for precise control of the position of the buffer assembly, enabling adjustment of the clamping force between the plates to adapt to different application requirements.

[0015] The sliding ball is slidably mounted on the upper end of the convex-shaped limiting groove. A stabilizing rod is rotatably mounted on the lower end of the sliding ball. The cross-sectional shape of the stabilizing rod is Y-shaped. The Y-shaped stabilizing rod limits the sliding ball and reduces friction between the stabilizing rod and the sliding ball. A connecting rod is fixedly mounted on the lower end of the Y-shaped stabilizing rod. A buffer cylinder is fixedly mounted on the lower end of the connecting rod. A buffer spring is engaged between the buffer cylinder and the connecting rod.

[0016] The combination of a convex-shaped limiting groove and a Y-shaped stabilizer bar provides better limiting effect, ensuring the sliding ball moves within its permissible range of motion. This improvement in limiting and stability helps prevent unwanted component swaying and shaking, thus maintaining the overall stability of the plate. The Y-shaped stabilizer bar design not only provides better limiting but also reduces friction between the stabilizer bar and the sliding ball. This helps improve the efficiency of the locking mechanism, reduce energy loss, and also extend the service life of components. The combined design of the connecting rod, buffer cylinder, and buffer spring provides cushioning and shock absorption. It protects the internal components of the plate from damage when subjected to external impacts or vibrations. By reducing friction and providing shock absorption, this improvement helps reduce the maintenance requirements of the mechanism. This reduces maintenance costs and downtime, improving the economics of the plate.

[0017] The rotating rod has the same shape as the fixed rod. A limiting block is rotatably installed at the front end of the rotating rod. The cross-sectional shape of the limiting block is "T". The "T"-shaped limiting block allows the rotating rod to move within a specified range. At the same time, the "T"-shaped limiting block firmly connects the two plates. The other end of the "T"-shaped limiting block is slidably installed on the groove on the side of the edge sealing plate.

[0018] The shape of the rotating rod matches that of the fixed rod, improving the interchangeability of components and making them easier to maintain and replace. The "T"-shaped limit block design provides stable limit control. It ensures that the rotating rod moves within its permissible range of motion and prevents movement beyond the specified range. By sliding the "T"-shaped limit block onto the groove on the side of the edge banding plate, the locking mechanism can be more securely connected to the edge banding plate. This ensures a stable connection between the edge banding portion of the plate and the locking mechanism, making it less susceptible to external impacts or vibrations. This limit block design provides more precise position control, helping to ensure accurate positioning of the plate. This design also helps improve the durability of the locking mechanism by reducing friction and wear between mechanism components, extending the service life of the mechanism.

[0019] The adjustment mechanism includes a baffle, a limiting cylinder, a rotating cylinder, an adjustment groove, a rotating groove, an adjustment rope, and a stop block. The baffle is installed on the side of the plate. The side of the baffle has an array of limiting cylinders. The rotating cylinder is rotatably installed on the side of the limiting cylinder. An adjustment groove is provided at the center of the rotating cylinder. The adjustment groove is elliptical in shape. The elliptical adjustment groove can reduce the friction with the fixed rod during rotation. At the same time, it provides better squeezing force for the locking mechanism during rotation, so that the two plates are separated. The side of the rotating cylinder has a rotating groove. An adjustment rope is installed on the rotating groove. The stop block is fixedly installed on the side of the baffle. When the length of the adjustment rope is pulled to half the circumference of the rotating cylinder, the stop block will fix the adjustment rope.

[0020] The elliptical adjustment groove design reduces friction with the fixed rod, providing smoother movement during the rotation of the adjustment mechanism. This helps ensure the reliability and stability of the locking mechanism. The elliptical adjustment groove also allows the rotating cylinder to provide better clamping force during rotation. This facilitates the separation of the two plates, making them easier to disengage and reducing the workload during maintenance or adjustment. Rotation grooves are provided on the sides of the rotating cylinder, providing an additional way to reduce friction with the adjustment rope. The elliptical adjustment groove and adjustment rope design simplify the operation of the adjustment mechanism, making it easier to use and allowing for easy adjustment of the clamping force between the plates as needed. Precise control of the adjustment mechanism can be achieved by adjusting the length of the adjustment rope to meet the clamping requirements of different application scenarios. This design helps reduce friction and wear, improving the durability of the locking mechanism and extending its service life. When the length of the adjustment rope reaches half the circumference of the rotating cylinder, the stopping block prevents further pulling, ensuring the stability of connection or separation and preventing accidental disengagement. This improves safety in the workplace and application. The presence of the stopping block prevents excessive pulling of the adjustment rope, thus preventing unnecessary stress or damage to the locking mechanism or connecting components.

[0021] The limiting cylinder has a funnel-shaped cross-section. The funnel-shaped limiting cylinder and the fixed cylinder cooperate to provide guidance for the locking mechanism. The fixed cylinder reduces the friction of the limiting cylinder during the sliding process. At the same time, the limiting cylinder has the function of limiting and rotating the rotating cylinder.

[0022] The funnel-shaped limiting cylinder acts as a guide for the fixed cylinder, meaning that during assembly or adjustment, the limiting cylinder helps guide the fixed cylinder into the correct position. Because the funnel shape reduces the contact area between the limiting cylinder and the fixed cylinder, friction is reduced. This allows the locking mechanism to move more smoothly, facilitating installation. The guiding and friction-reducing properties contribute to improved reliability of the locking mechanism, reducing the risk of component wear and mechanism damage. This improves assembly accuracy, reduces incorrect installation, and saves time and labor costs. The fixed cylinder also reduces friction on the limiting cylinder during sliding.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. This invention designs a locking mechanism; the design of the locking mechanism ensures stable fixation between the plates. The locking mechanism, through the funnel-shaped limiting cylinder, helps reduce friction between internal parts, improves installation efficiency, and reduces friction and improves stability, meaning that the parts of the mechanism are less susceptible to wear and damage. The locking mechanism effectively fixes the fixing rod through the concave groove, reducing the risk of the fixing rod falling off or moving due to external impact or vibration, and improving the safety of the locking mechanism.

[0025] 2. This invention designs a sliding ball and a stabilizing bar; the combination of the sliding ball and the stabilizing bar provides a limiting function, ensuring that the sliding ball moves within its allowed range of motion, thereby maintaining the stability of the plate. This helps prevent unnecessary component swaying and shaking, and the sliding ball also reduces friction with the stabilizing bar, improving the efficiency of the mechanism and reducing energy loss.

[0026] 3. This invention employs an adjustment mechanism that precisely controls the clamping force or connection state by adjusting the rope length. This provides highly precise adjustment performance to meet the needs of various applications. Furthermore, by introducing components such as a limit cylinder and a stop block, the reliability and stability of operation are improved, ensuring the stability and consistency of connection or separation. The adjustment mechanism with the stop block prevents further pulling when the adjusted rope length reaches a specific position, thereby enhancing safety in the workplace and applications.

[0045] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0046] like Figure 1 , 2 As shown in Figures 3 and 4, the polyurethane-sealed rock wool sandwich panel provided by the present invention includes a panel 1, a locking mechanism 2, and an adjusting mechanism 3. The locking mechanism 2 is installed on one side of the panel 1, and the adjusting mechanism 3 is installed on the other side of the panel 1. The locking mechanism 2 converts the outward displacement of the fixed rod 27 into the horizontal displacement of the sliding cylinder 24, and converts the horizontal displacement of the sliding cylinder 24 into the pressure of the rotating rod 29 on the partition 21, thereby clamping and fixing the partition 21 and the baffle 31. The adjusting mechanism 3 converts the pulling force of the adjusting rope 36 into the rotational force of the rotating cylinder 33. The rotating cylinder 33 presses the fixed rod 27 in the locking mechanism 2, so that the fixed rod 27 is aligned with the side of the fixed cylinder 22, thereby separating the partition 21 and the baffle 31. Through the cooperation between the locking mechanism 2 and the adjusting mechanism 3, the fixation between the two panels 1 can be ensured, thereby improving the stability between the panels 1.

[0047] When two plates come into contact, due to the combined design of the locking mechanism 2 and the adjusting mechanism 3, the height between the two plate bodies 1 is ensured to be fixed. The locking mechanism 2 clamps the partition plate 21 and the baffle plate 31 through the coordinated action of the sliding cylinder 24 and the rotating rod 29, preventing loosening and shaking between them, thus improving the stability between the plate bodies 1. Through the adjusting mechanism 3, the separation distance between the plate bodies 1 can be easily adjusted. The force of the adjusting rope 36 is converted into the rotational force of the rotating cylinder 33, making the fixed rod 27 in the locking mechanism 2 align with the side of the fixed cylinder 22, thus achieving the separation between the partition plate 21 and the baffle plate 31. This makes the installation and maintenance of the sandwich panel more flexible and convenient. Through the interaction of the locking mechanism 2 and the adjusting mechanism 3, it can be ensured that the clamping between the edge sealing plates is very firm, thus improving the overall stability and strength of the sandwich panel. The design of the fixed cylinder 22 and the fixed rod 27 makes the locking mechanism 2 have good stability and can maintain the clamping state of the plates under the action of vibration or external forces.

[0048] As Figure 2 , 5 , 6, 7, 8, and 13 show that the locking mechanism 2 includes a partition plate 21, a fixed cylinder 22, a sliding groove 23, a sliding cylinder 24, a compression spring 25, a fixed groove 26, a fixed rod 27, a sliding ball 28, and a rotating rod 29. The partition plate 21 is fixedly installed on the side of the plate body 1. A stable groove 211 is provided on the partition plate 21. The fixed cylinder 22 is fixedly installed on the side of the partition plate 21. The cross-sectional shape of the front end of the fixed cylinder 22 is an isosceles trapezoid. When the fixed cylinder 22 is installed with the adjusting mechanism 3, it can reduce the friction during installation and can quickly find the installation position during the installation process. A sliding groove 23 is provided inside the fixed cylinder 22. The sliding cylinder 24 is slidably installed inside the sliding groove 23. The cross-sectional shapes of both ends of the sliding cylinder 24 are in the shape of "tu". The "tu"-shaped sliding cylinder 24 has a stabilizing effect during the sliding process and has a stable and compact effect on the internal parts. The front end of the "tu"-shaped sliding cylinder 24 is clamped with a compression spring 25. A fixed groove 26 is provided on the side of the fixed cylinder 22. The cross-sectional shape of the fixed groove 26 is in the shape of "concave". The fixed rod 27 is rotatably installed inside the "concave"-shaped fixed groove 26. The sliding ball 28 is slidably installed at the front end of the fixed rod 27. The rotating rod 29 is rotatably installed at the other end of the fixed cylinder 22.

[0049] When the locking mechanism 2 contacts the adjusting mechanism 3, the locking mechanism 2 ensures stable fixation between the partition 21 and the baffle 31 through the coordinated action of components such as the partition 21, the fixed cylinder 22, the sliding groove 23, and the sliding cylinder 24. The sliding cylinder 24 has an "earth"-shaped cross-section and a compression spring 25, which makes the sliding cylinder 24 stable during sliding, effectively preventing the shaking and loosening of the internal parts of the sandwich panel. At the same time, this also helps to make the part layout more compact and improve the overall performance. The use of the compression spring 25 provides additional compression force, enhances the clamping effect between the plates 1, and improves the stability and strength of the overall sandwich panel. The front end cross-section of the fixed cylinder 22 is an isosceles trapezoid, which reduces friction during installation and allows for quick location of the correct installation position, reducing installation complexity and time, and improving production efficiency. The design of the locking mechanism 2 ensures the stability and compactness of the internal parts. The coordinated action between components such as the sliding cylinder 24, the fixed rod 27, and the sliding ball 28 ensures that they are not easily affected by external impacts or vibrations during use, thereby extending the service life of the components. A fixing rod 27 is installed within the concave fixing groove 26, which ensures that the fixing rod 27 is stably positioned within a certain range, thus achieving the stability of the locking mechanism. At the same time, the concave fixing groove 26 effectively fixes the fixing rod 27, reducing the risk of the fixing rod 27 falling off or moving due to external impact or vibration, and improving the safety of the locking mechanism.

[0050] like Figure 7 and 8 As shown, the cross-sectional shape of the fixing rod 27 is "L" shaped. The short side of the "L" shaped fixing rod 27 slides between the "E" shaped sliding cylinders 24. When the "E" shaped sliding cylinders 24 slide, they play a role in stabilizing the rotation of the fixing rod 27. The front end of the fixing rod 27 is triangular. When the fixing rod 27 is squeezed, the triangular front end has a larger contact area to squeeze the adjusting mechanism 3, making the fixing rod 27 more stable when squeezed. The side of the fixing cylinder 22 is provided with a limit groove 271.

[0051] When the fixing rod 27 in the locking mechanism 2 has an "L"-shaped cross-section, its short side slides between the "U"-shaped sliding cylinders 24, providing additional stability. During sliding, the "L"-shaped fixing rod 27 rotates stably, ensuring the secure locking and clamping of the plate 1. Furthermore, the triangular shape at the front end of the fixing rod 27 provides a larger contact area during compression, allowing the fixing rod 27 to be more stably compressed by the adjusting mechanism 3, improving the efficiency of compression force transmission and ensuring the stability of the sandwich panel under different conditions. The side of the fixing cylinder 22 has a limiting groove 271, which further increases control capability. The limiting groove 271 can be used to limit the range of motion of the fixing rod 27, thereby ensuring precise positioning and secure fixing between the plates 1 when needed. In addition, the interaction between the fixing rod 27 and the sliding cylinder 24 reduces friction, lowers energy loss, and makes the locking mechanism more efficient. This design improvement enhances the overall system performance and stability.

[0052] like Figure 5 As shown, the cross-sectional shape of the limiting groove 271 is convex, and the upper end of the convex limiting groove 271 is arc-shaped, so that the sliding ball 28 and the limiting groove 271 are interference fit, and the sliding ball 28 slides between the fixed rod 27, reducing the friction between the sliding ball 28 and the fixed rod 27, and playing a stabilizing role for the sliding cylinder 24 during the sliding process.

[0053] When the limiting groove 271 limits the sliding ball 28, the convex shape of the limiting groove 271, combined with the arc-shaped upper end, achieves an interference fit between the sliding ball 28 and the limiting groove 271. This helps reduce friction between the sliding ball 28 and the fixed rod 27, improving the stability and performance of the entire locking mechanism. Less friction extends the service life of components, and the interference fit and stable interaction between the sliding ball 28 and the limiting groove 271 keep the sliding cylinder 24 stable during sliding. This stability is crucial for ensuring that the position of the internal parts of the sandwich panel does not change, especially under vibration or impact conditions. The arc-shaped upper end and the interference fit design provide more precise position control. Reduced friction and improved stability mean that the components of the locking mechanism 2 are less susceptible to wear and damage, thus requiring less maintenance. This helps reduce maintenance costs and downtime. The limiting groove 271 also enables precise control of the position of the buffer assembly, allowing adjustment of the clamping force between the sandwich panels to meet different application requirements.

[0054] like Figure 6 , 8As shown in Figures 9 and 10, the sliding ball 28 is slidably mounted on the upper end of the convex-shaped limiting groove 271. A stabilizing rod 281 is rotatably mounted on the lower end of the sliding ball 28. The cross-sectional shape of the stabilizing rod 281 is Y-shaped. The Y-shaped stabilizing rod 281 can better limit the sliding ball 28 and reduce the friction between the stabilizing rod 281 and the sliding ball 28. A connecting rod 282 is fixedly mounted on the lower end of the Y-shaped stabilizing rod 281. A buffer cylinder 283 is fixedly mounted on the lower end of the connecting rod 282. A buffer spring 284 is engaged between the buffer cylinder 283 and the connecting rod 282.

[0055] The combination of the convex-shaped limiting groove 271 and the Y-shaped stabilizer bar 281 provides better limiting effect, ensuring that the sliding ball 28 moves within its permissible range of motion. This improvement in limiting and stability helps prevent unnecessary component swaying and shaking, thus maintaining the overall stability of the sandwich panel. The design of the Y-shaped stabilizer bar 281 not only provides better limiting but also reduces friction between the stabilizer bar 281 and the sliding ball 28. This helps improve the efficiency of the locking mechanism 2, reduce energy loss, and also extend the service life of the components. The combined design of the connecting rod 282, the buffer cylinder 283, and the buffer spring 284 provides cushioning and shock absorption. It protects the internal components of the sandwich panel from damage when subjected to external impacts or vibrations. By reducing friction and providing shock absorption, this improvement helps reduce the maintenance requirements of the mechanism. This reduces maintenance costs and downtime, improving the economics of the sandwich panel.

[0056] like Figure 5 , 6 As shown in Figure 12, the shape of the rotating rod 29 is consistent with the shape of the fixed rod 27. A limiting block 291 is rotatably installed at the front end of the rotating rod 29. The cross-sectional shape of the limiting block 291 is "T" shaped, and the other end of the "T" shaped limiting block 291 is slidably installed on the groove on the side of the sealing plate.

[0057] The shape of the rotating rod 29 matches that of the fixed rod 27, improving the interchangeability between components and making them easier to maintain and replace. The design of the "T"-shaped limit block 291 provides stable limit control. It ensures that the rotating rod 29 moves within its permissible range of motion and prevents movement beyond the specified range. By sliding the "T"-shaped limit block 291 onto the groove on the side of the edge banding plate, the locking mechanism 2 can be more securely connected to the edge banding plate. This ensures a stable connection between the edge banding portion of the sandwich panel and the locking mechanism 2, making it less susceptible to external impacts or vibrations. This limit block 291 design provides more precise position control, helping to ensure accurate positioning of the sandwich panel. This design also helps improve the durability of the locking mechanism because it reduces friction and wear between mechanism components, extending the service life of the mechanism.

[0058] like Figure 2 , 4 As shown in 11, 14, and 16, the adjustment mechanism 3 includes a baffle 31, a limiting cylinder 32, a rotating cylinder 33, an adjustment groove 34, a rotating groove 35, an adjustment rope 36, and a stop block 37. The baffle 31 is installed on the side of the plate 1. The limiting cylinder 32 is arranged in an array on the side of the baffle 31. The rotating cylinder 33 is rotatably installed on the side of the limiting cylinder 32. The center of the rotating cylinder 33 has an adjustment groove 34. The adjustment groove 34 is elliptical in shape. The elliptical adjustment groove 34 can reduce the friction with the fixed rod 27 during rotation. At the same time, it provides better squeezing force for the locking mechanism 2 during rotation, making it easier to separate the two plates 1. The rotating groove 35 is provided on the side of the rotating cylinder 33. The adjustment rope 36 is installed on the rotating groove 35. The stop block 37 is fixedly installed on the side of the baffle 31. When the length of the adjustment rope 36 is pulled to half the circumference of the rotating cylinder 33, the stop block 37 will fix the adjustment rope 36.

[0059] When the elliptical adjusting groove 34 and adjusting rope 36 rotate, the design of the elliptical adjusting groove 34 reduces friction with the fixed rod 27, thus providing smoother movement during the rotation of the adjusting mechanism 3. This helps ensure the reliability and stability of the locking mechanism. The design of the elliptical adjusting groove 34 also allows the rotating cylinder 33 to provide better clamping force during rotation. This helps separate the two plates 1, making them easier to untie, thereby reducing the workload during maintenance or adjustment. The rotating cylinder 33 has a rotating groove 35 on its side, which provides an additional way to reduce friction with the adjusting rope 36. The design of the elliptical adjusting groove 34 and adjusting rope 36 simplifies the operation of the adjusting mechanism 3, making it easier to use and allowing for easy adjustment of the clamping force between the sandwich plates as needed. By adjusting the length of the adjusting rope 36, precise control of the adjusting mechanism 3 can be achieved to meet the clamping requirements of different application scenarios. This design helps reduce friction and wear, improves the durability of the locking mechanism, and extends the service life of the mechanism.

[0060] like Figure 14 and 15 As shown, the limiting cylinder 32 has a funnel-shaped cross-section. The funnel-shaped limiting cylinder 32 guides the fixed cylinder 22, and the fixed cylinder 22 reduces the friction of the limiting cylinder 32 during sliding. At the same time, the limiting cylinder 32 limits and rotates the rotating cylinder 33.

[0061] When the fixed cylinder 22 fixes the adjusting mechanism 3, the funnel-shaped limiting cylinder 32 acts as a guide for the fixed cylinder 22. This means that during assembly or adjustment, the limiting cylinder 32 helps guide the fixed cylinder 22 into the correct position. Because the funnel-shaped limiting cylinder 32 reduces the contact area with the fixed cylinder 22, friction is reduced. This allows the locking mechanism to move more smoothly, and the guiding and friction-reducing characteristics help improve the reliability of the locking mechanism, reducing the risk of parts wear and mechanism damage. This improves assembly accuracy, reduces incorrect installation, and saves time and labor costs. The fixed cylinder 22 also reduces friction on the limiting cylinder 32 during sliding.

[0062] During operation, when the two plates 1 come into contact, the partition 21 on the right side of the plates aligns with the fixed cylinder 22. The sliding groove 23 inside the fixed cylinder 22 contains a sliding cylinder 24. The pressing action of the fixed rod 27 causes the sliding cylinder 24 to move horizontally, simultaneously causing the rotating rod 29 to move vertically, thus fixing the rotating rod 29 to the partition 21. The stabilizing groove 211 limits the position of the limiting block 291. Simultaneously, the fixed cylinder 22 passes through the limiting cylinder 32 in the baffle 31. The rod 27 unfolds to limit and fix the baffle 31. The rotating cylinder 33 on the limiting cylinder 32 is driven to rotate by the pulling of the adjusting rope 36. The adjusting groove 34 in the middle of the rotating cylinder 33 rotates and squeezes the fixed rod 27. The sliding ball 28 at the lower end of the fixed rod 27 pushes the buffer cylinder 283 at the lower end. The buffer cylinder 283 plays a buffering role. The fixed rod 27 is parallel to the fixed cylinder 22, which can be quickly pulled out. The rotating rod 29 fixes the limiting block 291 to the partition 21 through the sliding cylinder 24.
