Description

Technical Field

[0001] This invention relates to the field of architectural decoration technology, specifically to a Great Wall panel and its connecting structure. Background Technology

[0002] As a common wall decoration material, the ease of installation, the strength of the connection, and the adaptability to curved surfaces are important technical indicators for Great Wall panels. Existing connection methods for Great Wall panels mostly use screw fixing or simple snap-fit ​​connections, which suffer from low installation efficiency, poor adaptability to non-flat wall surfaces, and difficulties in disassembly and maintenance. For example, when installing on curved walls, traditional rigid connection structures are difficult to fit tightly, resulting in excessively large seams or uneven installation. Furthermore, while existing connection methods achieve rapid installation, they often fail to balance the strength of the connection with the ease of disassembly. Summary of the Invention

[0003] To overcome the above-mentioned technical problems, the present invention provides a Great Wall panel and its connecting structure, which can achieve rapid positioning, installation and disassembly, adapt to curved surface installation and ensure a firm connection.

[0004] To achieve the above objectives, the present invention provides a Great Wall panel connection structure, the connection structure comprising: Two flexible connecting parts are respectively set on one side of one Great Wall panel and on the other side of another Great Wall panel that is adjacent to and connected to one Great Wall panel; A snap-fit ​​assembly is disposed on top of one of the flexible connectors; The mounting slot assembly is disposed on top of another of the flexible connectors and is matched and connected with the snap fastener; A disassembly assembly, one end of which is connected to the latching assembly, and the other end of which is disposed on the top of the front side of a flexible connection near the latching assembly, for adjusting the latching assembly to disengage from the mounting slot assembly; A magnetic attraction component is disposed in the middle of the two flexible connecting parts.

[0005] Preferably, the snap-fit ​​assembly includes: A wedge-shaped clamp head is provided perpendicularly to the flexible connecting part and outwardly, and the front end of the wedge-shaped clamp head is provided with a guide slope. Two elastic locking tongues are provided, with one end of each elastic locking tongue symmetrically disposed within the cavity of the wedge-shaped locking head, and the other ends of each elastic locking tongue partially protruding from the upper and lower surfaces of the wedge-shaped locking head, respectively.

[0006] Preferably, the mounting slot assembly includes: A through groove is provided within the flexible connecting part and is matched and connected with the wedge-shaped clamp head to accommodate the wedge-shaped clamp head; Two slots are respectively disposed on the upper and lower walls of the through groove and are locked to two elastic locking tongues.

[0007] Preferably, the disassembly assembly includes: Two linkage rods, one end of each linkage rod is inserted into the wedge-shaped locking head and respectively contact and connect with the bottom ends of the two elastic locking tongues; The L-shaped unlocking push rod has its vertical rod extending through the top of the front of one of the flexible connecting parts. The vertical rod of the L-shaped unlocking push rod is connected to the other end of the two linkage rods. When the L-shaped unlocking push rod is pushed towards the wedge-shaped locking head, it pushes the elastic locking tongue out of the slot along with the linkage rod, thereby achieving quick disassembly.

[0008] Preferably, the disassembly assembly further includes a reset spring, which is disposed at the bottom of the crossbar of the L-shaped unlocking push rod to ensure that the L-shaped unlocking push rod automatically resets after being pushed.

[0009] Preferably, the magnetic attraction component includes multiple sets of spaced permanent magnets, the magnetic poles of the permanent magnets are arranged in an alternating NSNS pattern, and the magnetic poles of the magnetic attraction components on the two flexible connecting portions are arranged in opposite directions.

[0010] Preferably, the permanent magnet is made of neodymium iron boron magnet.

[0011] Preferably, the flexible connection is made of a composite material of polyurethane elastomer and glass fiber, and is bent and deformed along the width direction.

[0012] A second aspect of the present invention provides a Great Wall panel, the Great Wall panel comprising: Great Wall panel body; The connection structure includes: Two flexible connecting parts are respectively set on one side of one Great Wall panel and on the other side of another Great Wall panel that is adjacent to and connected to one Great Wall panel; A snap-fit ​​assembly is disposed on top of one of the flexible connectors; The mounting slot assembly is disposed on top of another of the flexible connectors and is matched and connected with the snap fastener; A disassembly assembly, one end of which is connected to the latching assembly, and the other end of which is disposed on the top of the front side of a flexible connection near the latching assembly, for adjusting the latching assembly to disengage from the mounting slot assembly; A magnetic attraction component is disposed in the middle of the two flexible connecting parts.

[0013] Preferably, the Great Wall panel body 1 includes: The decorative part is located on the front side of the Great Wall panel body 1; Microporous sound-absorbing material is disposed within the decorative part.

[0014] Through the above technical solutions, the Great Wall panel and its connecting structure, through the cooperation of buckles and slots, combined with the pre-positioning of the magnetic components, achieve rapid and precise alignment and installation of the Great Wall panel, significantly improving construction efficiency. The flexible connection design allows the Great Wall panel to bend within a certain range, thus adapting to the installation on non-planar walls such as arcs and cylinders, expanding application scenarios. The unique elastic locking tongue and slot locking structure achieve the convenience of "insert and lock" while ensuring the mechanical strength and reliability of the connection. The setting of the disassembly component enables tool-free one-click quick unlocking and disassembly, greatly facilitating later maintenance, replacement, or local adjustments. The setting of the magnetic components not only assists in initial positioning but also provides additional connection force in addition to mechanical locking, making the connection more stable and effectively eliminating abnormal noises caused by thermal expansion and contraction or slight deformation.

It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0017] like Figure 1 The diagram shown is a schematic representation of the structure of two adjacent Great Wall planks in a Great Wall plank connection structure according to an embodiment of the present invention. Figure 1In this design, the Great Wall panel connection structure may include two flexible connecting parts 2, a snap-fit ​​assembly 3, a mounting groove assembly 4, a disassembly assembly 5, and a magnetic suction assembly 6. Specifically, the two flexible connecting parts 2 are respectively disposed on one side of one Great Wall panel and the other side of another Great Wall panel adjacent to one Great Wall panel; the snap-fit ​​assembly 3 is disposed on the top of one flexible connecting part 2, and the mounting groove assembly 4 is disposed on the top of the other flexible connecting part 2 and is matched and connected with the snap-fit; one end of the disassembly assembly 5 is connected to the snap-fit ​​assembly 3, and the other end of the disassembly assembly 5 is disposed on the top of the front of one flexible connecting part 2 near the snap-fit ​​assembly 3, for adjusting the snap-fit ​​assembly 3 to disengage from the mounting groove assembly 4; and the magnetic suction assembly 6 is disposed in the middle of the two flexible connecting parts 2.

[0018] Through the above technical solutions, the flexible connection part of the Great Wall panel provides deformation capability to adapt to curved surface installation; the cooperation between the buckle and the mounting groove assembly is the core of achieving rapid mechanical connection; the disassembly assembly gives the structure reversibility and facilitates maintenance; the magnetic component achieves automatic pre-alignment and auxiliary fixation before mechanical connection. This structure integrates convenience, adaptability and reliability. During installation, the operator only needs to bring the two panels close together for adsorption and then push them in to complete the locking. Single person can operate efficiently, greatly improving installation efficiency, while ensuring the mechanical strength and disassembly of the connection, laying the foundation for standardized installation and reuse of the product.

[0019] like Figure 2 The diagram shown is a partial structural schematic of a snap-fit ​​assembly and a disassembly assembly for a Great Wall panel connection structure according to an embodiment of the present invention; Figure 2 In order to achieve the guiding connection and bidirectional locking of the snap-fit ​​assembly 3 and ensure the reliability of the connection, in one embodiment of the present invention, the snap-fit ​​assembly 3 may include a wedge-shaped snap-fit ​​head 31 and two elastic locking tongues 32. The wedge-shaped snap-fit ​​head 31 is arranged outward perpendicular to the flexible connection part 2, and the front end of the wedge-shaped snap-fit ​​head 31 is provided with a guide slope 311. One end of the two elastic locking tongues 32 is symmetrically arranged in the cavity of the wedge-shaped snap-fit ​​head 31, and the other end of the two elastic locking tongues 32 respectively partially protrudes from the upper surface and the lower surface of the wedge-shaped snap-fit ​​head 31. The guide slope 311 of the wedge-shaped snap-fit ​​head 31 can automatically correct minor deviations during initial insertion to achieve smooth insertion. The two elastic locking tongues 32 protrude from the upper and lower directions respectively to cooperate with the corresponding slots 42 on the upper and lower sides of the mounting slot assembly 4 for locking. During the insertion process, the two locking tongues are squeezed and contracted by the inner wall of the slot 42. After they are in place, they simultaneously spring open up and down to achieve bidirectional locking. The traditional one-way snap-fit ​​force is improved to two-way force, which significantly improves the resistance to pull-out force and torsional load, making the connection point more stable. It is suitable for application scenarios with certain load-bearing or vibration requirements, and effectively prevents the connection from loosening due to single-point failure.

[0020] like Figure 3The diagram shown is a structural schematic of a mounting groove assembly for a Great Wall panel according to an embodiment of the present invention; in Figure 3 In order to achieve the locking engagement between the mounting slot assembly 4 and the snap-fit ​​assembly 3, and to ensure the overall stability of the Great Wall panel connection, in one embodiment of the present invention, the mounting slot assembly 4 may include a through slot 41 and two slots 42. The through slot 41 is disposed within the flexible connecting part 2 and is matched and connected to the wedge-shaped snap-fit ​​head 31 to accommodate the wedge-shaped snap-fit ​​head 31. The two slots 42 are respectively disposed on the upper and lower groove walls of the through slot 41 and are locked and connected to the two elastic locking tongues 32. The through slot 41 provides a precise track space for the insertion of the wedge-shaped snap-fit ​​head 31, ensuring a smooth and straight insertion process. The positions of the two slots 42 disposed on the upper and lower groove walls of the through slot 41 are precisely calculated to ensure that when the wedge-shaped snap-fit ​​head 31 is fully inserted, it is exactly aligned with the ends of the two elastic locking tongues 32. Preferably, the slots 42 can be designed as blind holes, through holes, or recesses. The symmetrical slots 42 serve as locking points, making the connection force distribution more uniform and improving the overall stability.

[0021] exist Figure 2 In order to facilitate the installation and disassembly of the Great Wall panel and enable convenient subsequent maintenance, in one embodiment of the present invention, the disassembly component 5 includes two linkage rods 51: a linkage rod 51 and an L-shaped unlocking push rod 52. One end of each linkage rod 51 is inserted into the wedge-shaped locking head 31 and is respectively connected to the bottom end of the two elastic locking tongues 32. The vertical rod 522 of the L-shaped unlocking push rod 52 extends out of the top of the front of a flexible connecting part 2. The vertical rod 522 of the L-shaped unlocking push rod 52 is connected to the other end of the two linkage rods 51. When the L-shaped unlocking push rod 52 is pushed to move towards the wedge-shaped locking head 31, it causes the linkage rod 51 to squeeze the elastic locking tongues 32 out of the slot 42, thereby achieving quick disassembly. When disassembly is required, push the L-shaped unlocking push rod 52. Its crossbar 521 drives the linkage rod 51 to move. The linkage rod 51 simultaneously acts on the roots of the two elastic locking tongues 32, forcing them to overcome their own elastic restoring force and move towards each other (i.e., the upper locking tongue retracts downward and the lower locking tongue retracts upward), so that their ends are simultaneously disengaged from the upper and lower slots 42. Once the locking tongues are disengaged, the locking state is immediately released, and the Great Wall plate can be pulled out and separated. This design simplifies the unlocking action to a single press, without the need for any tools, greatly simplifying the disassembly process and reducing the difficulty and cost of maintenance, replacement, or partial modification, truly realizing the product's quick and easy disassembly function.

[0022] exist Figure 2In order to achieve the reset of the disassembly component 5 and ensure the stability and reliability of the mechanism, in one embodiment of the present invention, the disassembly component 5 also includes a reset spring 53, which is set at the bottom of the crossbar 521 of the L-shaped unlocking push rod 52 to ensure that the L-shaped unlocking push rod 52 automatically resets after being pushed. When the disassembly operation is completed and the pushed L-shaped unlocking push rod 52 is released, the elastic potential energy stored in the reset spring 53 is released, and the L-shaped unlocking push rod 52 is automatically pushed back to the initial position. At the same time, the two elastic locking tongues 32 connected to the L-shaped unlocking push rod 52 through the linkage rod 51 also automatically return to the initial, slightly protruding pre-locking state under the combined action of their own elasticity and / or the force transmitted by the reset spring 53 through the linkage rod 51. This ensures that the disassembly mechanism can automatically reset after each use, preparing for the next installation and locking, avoiding installation failure due to the failure of the component to reset, improving the reliability and ease of use of the product, and avoiding problems that may be caused by human forgetting to reset.

[0023] exist Figure 1 In order to achieve precise positioning and sufficient adsorption capacity of adjacent panels during installation, in one embodiment of the present invention, the magnetic adsorption component 6 includes multiple sets of spaced permanent magnets 61. The magnetic poles of the permanent magnets 61 are arranged in an alternating NSNS pattern, and the magnetic poles of the magnetic adsorption components 6 on the two flexible connecting parts 2 are arranged in opposite directions. The alternating arrangement allows more effective NS magnetic pole pairs to be formed within a unit length, thereby maximizing the magnetic attraction force within a limited installation space and achieving stronger pre-adsorption. When the two panels are close together, due to the strictly opposite magnetic poles, a strong, directional attraction force is generated, which not only guides the two panels closer in the direction perpendicular to the panel surface, but also in the horizontal direction (the length and height direction of the panel), the misaligned magnetic poles generate a corrective force, guiding the two panels to slide to the precise position where the magnetic poles are aligned one-to-one. The self-alignment function greatly simplifies the alignment operation during installation, making it easier for the buckle to align with the slot 42, especially facilitating quick and accurate installation in situations with poor visibility or high-altitude operations, significantly improving the installation success rate and efficiency, and meeting more usage scenarios.

[0024] exist Figure 1 In order to ensure the stability of the material connection of the Great Wall panel and provide long-term effective strong magnetic force, in one embodiment of the present invention, the permanent magnet 61 is made of neodymium iron boron magnet. This material can provide stronger adsorption force in the same volume, and the volume of the magnet can be made smaller, which is beneficial to the structural design of the flexible connection part 2 without affecting its bending performance. At the same time, it can adapt to different indoor and outdoor temperature and humidity environments, ensuring that the magnetic force does not significantly decay during the service life of the Great Wall panel, and ensuring the long-term effective reliability of the magnetic adsorption component 6.

[0025] To ensure that the flexible connection part 2 can withstand tensile and corrosion resistance during long-term use, and to guarantee that the connection part can maintain reliable mechanical connection and sealing even when bent, in one embodiment of the present invention, the flexible connection part 2 is made of a composite material of polyurethane elastomer and glass fiber, which can bend and deform along the width direction. This composite material is made by a specific ratio and process, and has the characteristics of toughness, high elasticity, fatigue resistance, high rigidity, high tensile strength and dimensional stability. This allows the flexible connection part 2 to elastically bend around an axis parallel to the length direction of the Great Wall board (i.e., in the width direction of the board) under the action of external force, and to basically return to its original shape after the external force is removed. This allows the Great Wall board with this connection structure to fit tightly into non-planar substrates such as cylinders, curved walls, and corners, greatly expanding its application range.

[0026] A second aspect of the present invention provides a Great Wall panel, which includes a Great Wall panel body 1 and a connecting structure. The connecting structure may include two flexible connecting parts 2, a snap-fit ​​assembly 3, a mounting groove assembly 4, a disassembly assembly 5, and a magnetic suction assembly 6. The two flexible connecting parts 2 are respectively disposed on one side of one Great Wall panel and on the other side of another Great Wall panel adjacent to and connected to one Great Wall panel. The snap-fit ​​assembly 3 is disposed on the top of one flexible connecting part 2, and the mounting groove assembly 4 is disposed on the top of the other flexible connecting part 2 and is matched and connected with the snap-fit. One end of the disassembly assembly 5 is connected to the snap-fit ​​assembly 3, and the other end of the disassembly assembly 5 is disposed near a flexible connecting part 3. The top of the front of the connecting part 2 is used to adjust the buckle assembly 3 to disengage from the mounting groove assembly 4. The magnetic suction assembly 6 is set in the middle of the two flexible connecting parts 2, so that adjacent Great Wall panels can be quickly connected through the connection structure. The Great Wall panel has a complete connection structure integrating the flexible connecting part 2, buckle / slot 42 and magnetic suction assembly 6 on both sides. During construction, there is no need to prepare complicated connectors or carry out tedious on-site processing. This greatly reduces the technical difficulty and requirements of on-site construction, shortens the construction period, and ensures the standardization and high quality of the final installation effect. It is suitable for interior and exterior decoration projects that require rapid deployment, frequent layout changes, or application to complex curved surfaces.

[0027] To meet the decorative needs of Great Wall panels and accommodate more application scenarios, in one embodiment of the present invention, the Great Wall panel body 1 includes a decorative section and a microporous sound-absorbing material. The decorative section is disposed on the front side of the Great Wall panel body 1, and the microporous sound-absorbing material is disposed within the decorative section. The decorative section is responsible for providing aesthetically pleasing wood grain, stone grain, and other finishing effects. The microporous sound-absorbing material integrated into the decorative panel can be composed of a large number of micropores with a pore size of 0.1-0.3mm, which can effectively absorb noise in specific frequency bands, improve the acoustic comfort of the usage environment, and achieve significant sound absorption and noise reduction functions. This upgrades it from a single decorative material to a functional building material with acoustic functions, broadening its application in places with sound environment requirements such as conference rooms, offices, cinemas, and home theaters, and meeting the increasingly higher requirements of green buildings and healthy buildings for indoor environmental quality.

[0028] Through the aforementioned technical solutions, the Great Wall panel and its connecting structure, using the cooperation of snap-fit ​​and slots combined with the pre-positioning of the magnetic components, achieve rapid and precise alignment and installation of the Great Wall panel, significantly improving construction efficiency. The flexible connection design allows the Great Wall panel to bend within a certain range, thus adapting to installation on non-planar walls such as curved and cylindrical surfaces, expanding its application scenarios. The unique elastic locking tongue and slot locking structure achieves the convenience of "insert and lock" while ensuring the mechanical strength and reliability of the connection. The disassembly component allows for tool-free one-click quick unlocking and disassembly, greatly facilitating subsequent maintenance, replacement, or partial adjustments. The magnetic components not only assist in initial positioning but also provide additional connecting force beyond mechanical locking, making the connection more stable and effectively eliminating abnormal noises caused by thermal expansion and contraction or slight deformation.
