Description

Technical Field

[0001] The present invention belongs to the technical field of building decoration, and in particular relates to a modular wall decoration device. Background Art

[0002] As the architectural decoration industry continues to demand more efficient and environmentally friendly construction, modular wall decoration devices are becoming a key research area due to their advantages such as ease of installation, rapid construction, and reduced environmental pollution. However, existing modular wall decoration devices still have some shortcomings in terms of structural design, adaptability, and construction flexibility, which hinder their widespread application and performance.

[0003] After searching, a modular wall and decoration method with publication number CN108049590B was found, with a publication date of December 11, 2018. This patent simplifies the construction process and increases the construction speed by setting up a modular wall system including an installation layer, a decoration layer, a keel support device and a connection structure. However, in this technical solution, the connection structure relies on fixings to achieve the connection between the installation layer and the keel support device, which may lead to high requirements for the flatness of the wall during the installation process, and the adaptability is subject to certain limitations under complex wall conditions. In addition, this solution does not fully consider the decoration requirements of different wall angles or special-shaped walls, which has formed certain constraints on its application in diverse scenarios.

[0004] After searching, a modular assembly device for architectural decoration with the publication number CN115370062B was found, and the publication date was June 23, 2023. This patent realizes the angle adjustment function of the fixed corner seat by setting up a modular assembly device including an assembly top plate and a fixed corner seat, using a flip axis to adapt to the decoration requirements of different wall angles. However, in this technical solution, although the design of the flip axis provides angle adjustment capability, its structure is relatively complex, which may increase manufacturing costs and installation difficulty. At the same time, this solution mainly focuses on the support and fixation of the assembly top plate, and fails to fully solve the problem of rapid connection and disassembly between the decorative components and the wall, which has a certain impact on its construction efficiency and the reusability of the device.

[0005] The above-mentioned issues indicate that existing modular wall decoration devices still have room for improvement in terms of adaptability to complex wall conditions, rapid connection and disassembly capabilities, and structural simplification. Therefore, the present invention provides a novel modular wall decoration device designed to improve the device's adaptability to diverse wall conditions, optimize the connection structure for rapid installation and disassembly, and simplify the overall design to reduce manufacturing and construction costs, thereby meeting the demand for efficient, flexible, and environmentally friendly decorative devices in the architectural decoration field. Summary of the Invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a modular wall decoration device.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a modular wall decoration device, comprising a supporting unit and a decorative unit, the decorative unit being installed on one side and the bottom of the supporting unit, the decorative unit comprising a fixing mechanism and an adjustment mechanism installed on one side of the upper end face edge of the fixing mechanism, connecting mechanisms being arranged on both sides of the bottom of the fixing mechanism, and limiting mechanisms being arranged on both sides of the lower end face edge of the fixing mechanism.

[0008] Preferably, the fixing mechanism includes a base plate and a embedding groove arranged in the inner cavity of the base plate, a clamping groove is provided on one side of the inner end surface of the embedding groove, a filter screen is provided at the bottom position of the embedding groove, the bottom of the base plate and the guide holes arranged around the bottom thereof, because the bottom of the inner cavity wall of the base plate is a concave structure, the staff can pour the construction glue from top to bottom into the inner cavity of the regulating cylinder, after the glue is received in the clamping groove, it passes downward through the bottom of the filter screen, and the glue continues to accumulate in the inner cavity of the base plate. When the liquid level exceeds the opened guide hole, the liquid will pass through the inner cavity of the guide hole and pour downward from the middle position along the bottom position of the outer end surface of the base plate into the single decorative panel, and the decorative panel will simultaneously pass through the opened guide hole inner cavity and be vertically adhered to the single decorative panel. At this time, the decorative panels are arranged in four groups in the single decorative panel, and the liquid spreads from the middle to the surrounding areas, so that the liquid can better adhere to and supplement the wall surface in the single decorative panel from the middle to the surrounding areas.

[0009] Preferably, the adjustment mechanism includes an adjustment cylinder and a clamping piece arranged at the top position of the outer end surface of the adjustment cylinder, the other side of the clamping piece is connected to a glue injection cylinder, both sides of the glue injection cylinder are fitted with the outer end surface of the adjustment cylinder through a support rod, a glue injection tube is installed at the bottom position of the glue injection cylinder, the other end of the glue injection tube is inserted into the outer end surface of the substrate, and the auxiliary glue is poured into the inner cavity of the glue injection cylinder from top to bottom. When sliding downward along the inner cavity of the substrate, very little glue will directly fall into the single decorative board, and most of the remaining auxiliary glue can be mixed with the building glue in the inner cavity of the substrate. After the liquid level of the mixed liquid is higher than the guide hole, it tilts downward. Pour it into a single decorative board so that the decorative board can be moistened with the auxiliary glue first while being adhered by the mixed glue, thereby strengthening the adhesion effect and improving the installation success rate, ensuring that the decorative board and the wall can obtain sufficient and uniform glue supply in the early stage, which is conducive to the rapid fixation and long-term stability of the decorative board. The decorative board can obtain more comprehensive adhesion support in the initial installation stage, which improves the installation success rate. When the mixed glue is poured into the decorative board, it can evenly cover the decorative board and the wall. This uniform covering method is conducive to the overall stability and installation quality of the decorative board, and improves the installation speed and firmness of the decorative board.

[0010] Preferably, the bottom of the adjustment tube is inserted and fitted into the inner cavity of the snap-fit ​​groove, so that the outer end wall of the adjustment tube is in contact with the inner cavity wall of the snap-fit ​​groove, and the other end of the glue injection tube is inserted into the outer end surface of the base plate. Preferably, the connection mechanism includes a first connecting tube and an assembly tray arranged on the inner end surfaces of multiple groups of first connecting tubes. A second connecting tube is vertically arranged in the middle position of the assembly tray, so that decorative panels falling downward due to gravity can be temporarily stored in the inner cavity of the base plate. When the staff needs to install multiple decorative panels in a single decorative panel, the second connecting tube is blocked, allowing the decorative panels to enter the inner cavity of the single decorative panel through the four groups of first connecting tubes, thereby achieving the effect of installing multiple decorative panels. When only a single decorative panel needs to be installed in a single decorative panel, the blocked second connecting tube is released, allowing the construction glue, auxiliary glue, and decorative panel to fall directly from the second connecting tube into the single decorative panel. By releasing the blocked second connecting tube, the construction glue, auxiliary glue, and decorative panel fall directly into the decorative panel, ensuring the accurate placement of the decorative panel. This precise installation method avoids waste of decorative panels, improves the success rate of installation, and ensures that each decorative panel can obtain sufficient adhesive adhesion, which is conducive to the firm installation and long-term stability of the decorative panels.

[0011] Preferably, the upper end surfaces of the first connecting tube and the second connecting tube are vertically inserted into the inner cavity of the guide hole, so that the connecting mechanism and the fixing mechanism become a whole.

[0012] Preferably, a limiting mechanism is clamped between the two groups of the first connecting tubes, and the limiting mechanism includes a limiting outer ring and a base arranged at the bottom position of the inner cavity wall of the limiting outer ring, and inner clamps are vertically arranged on both sides of the upper end surface of the base.

[0013] Preferably, the support unit includes a mounting frame and a sliding horizontal frame installed horizontally in the inner cavity of the mounting frame, the inner cavity of the mounting frame is vertically installed with a storage tube, and a track is arranged horizontally in the middle position of the sliding horizontal frame to adapt the entire device to be installed to the wall, and the two ends of the track are fixedly connected to fixed support points, so that the sliding horizontal frame can slide parallel to the upper end surface of the track with the opened lower cavity as the fulcrum, so that the entire device can be moved to the required accurate position.

[0014] The outer end surface of the wall is fitted through the middle interval of the connecting mechanism and the limiting mechanism, so that when the entire device moves, the inner end surfaces of the two sets of inner clips can clamp the outer end surface of the wall, thereby maintaining the stability of the device in the moving state.

[0015] The staff places the decorative panel to be installed into the inner cavity of the device from the top of the placement tube. Since the placement tube passes vertically downward through the inner cavity of the series ring, the series ring is stably clamped by the provided positioning frame and the horizontal insertion rod to maintain its stability during installation.

[0016] Preferably, the mounting frame includes an assembly frame and positioning frames arranged on both sides of the outer end surface of the assembly frame. The relatively arranged positioning frames are connected by transverse penetrating rods, a series ring is arranged between the two groups of transverse penetrating rods, and a positioning cross block is arranged transversely between the assembly frame and the positioning frame.

[0017] Preferably, the sliding cross frame includes a frame body and a lower cavity opened in the middle position of the bottom of the frame body, and vertical insertion holes are opened on both sides of the bottom of the frame body. The frame body is horizontally inserted into the inner cavity of the assembly frame.

[0018] Compared with the prior art, the technical effect of the present invention is as follows: the entire device to be installed is adapted to the wall, and the two ends of the track are fixedly connected to fixed support points, so that the sliding cross frame can slide parallel to the upper end surface of the track with the opened lower cavity as a fulcrum, so that the entire device can be moved to the required accurate position, and the staff will place the decorative panel to be installed from the top of the placement tube into the inner cavity of the device, and because the placement tube passes vertically downward through the inner cavity of the series ring, the series ring is stably clamped by the arranged positioning frame and the horizontal insertion rod to maintain its stability during installation.

[0019] The staff can pour the construction adhesive from top to bottom into the inner cavity of the regulating cylinder. After being received in the card slot, the adhesive passes downward through the bottom of the filter screen. The adhesive continues to accumulate in the inner cavity of the substrate. When the liquid level exceeds the opened guide hole, the liquid will pass through the inner cavity of the guide hole and pour downward from the middle position along the bottom position of the outer end surface of the substrate into the single decorative panel. The decorative panel will also pass through the opened guide hole inner cavity and fit vertically downward into the single decorative panel. At this time, the decorative panels are arranged in four groups in the single decorative panel, and the liquid spreads from the middle to the surrounding areas, so that the liquid can better adhere to and supplement the wall surface in the single decorative panel from the middle to the surrounding areas.

[0020] Pour the auxiliary glue into the inner cavity of the glue injection cylinder from top to bottom. When sliding downward along the inner cavity of the base plate, very small amount of glue will directly fall into the single decorative board. Most of the remaining auxiliary glue can be mixed with the construction glue in the inner cavity of the base plate. After the liquid level of the mixed liquid is higher than the guide hole, it is poured downward into the single decorative board. When the decorative board is adhered by the mixed glue, it can be wetted by the auxiliary glue first, thereby enhancing the adhesion effect and improving the success rate of installation.

[0021] When only a single decorative panel needs to be installed in a single decorative panel, the blocked second connecting pipe is released, allowing the construction adhesive, auxiliary adhesive and decorative panel to drop directly from the second connecting pipe into the single decorative panel, ensuring that each decorative panel can obtain sufficient adhesive adhesion, which is conducive to the firm installation and long-term stability of the decorative panel.

[0029] The present invention provides a modular wall decoration device, which is combined with the following Figure 1 To the attached Figure 5 The specific embodiments of the present invention are described in detail. Figure 1 As shown, the device comprises a support unit 1 and a decorative unit 2. The support unit 1 is used to secure the device to the wall and enable overall movement. The decorative unit 2, through its internal structural design, facilitates the installation and attachment of decorative panels. The support unit 1 comprises a mounting frame 21, a sliding crossbeam 22, a track 23, and a storage tube 24. The decorative unit 2 includes a fixing mechanism 3, an adjustment mechanism 4, a connecting mechanism 5, and a limiting mechanism 6.

[0030] The fixing mechanism 3 is one of the core components of the decoration unit 2. Its main structure is as follows: Figure 2As shown. The fixing mechanism 3 includes a base plate 7, an embedding groove 8 is provided in the inner cavity of the base plate 7, a snap-in groove 9 is provided on one side of the inner end surface of the embedding groove 8, a filter screen 10 is provided at the bottom of the embedding groove 8, and a guide hole 11 is provided around the bottom of the base plate 7. The bottom of the inner cavity wall of the base plate 7 is a concave structure. This design allows the construction glue to be poured in from the top and filtered through the filter screen 10 before flowing into the inner cavity of the base plate 7. When the liquid level of the glue exceeds the guide hole 11, the glue will flow out along the guide hole 11 and cover the surface of the decorative board. In this process, the glue diffuses from the middle to the surrounding area, ensuring that a uniform adhesion layer is formed between the decorative board and the wall. The snap-in groove 9 is designed to accommodate the adjustment cylinder 12, and the outer end wall of the adjustment cylinder 12 fits tightly with the inner cavity wall of the snap-in groove 9, thereby achieving stable installation of the adjustment cylinder 12 in the fixing mechanism 3.

[0031] Adjustment mechanism 4 Figure 3 As shown, it mainly consists of an adjustment cylinder 12, a clamping part 13, a glue injection cylinder 14 and a glue injection tube 15. The bottom of the adjustment cylinder 12 is inserted and matched with the inner cavity of the clamping groove 9. The glue injection cylinder 14 is fitted with the outer end face of the adjustment cylinder 12 through a support rod. The glue injection tube 15 is installed at the bottom of the glue injection cylinder 14, and the other end of the glue injection tube 15 is inserted into the outer end face of the substrate 7. During actual use, the staff pours the auxiliary glue into the inner cavity of the glue injection cylinder 14, and the glue flows along the glue injection tube 15 into the inner cavity of the substrate 7 and mixes with the construction glue. The mixed glue accumulates in the inner cavity of the substrate 7. When the liquid level exceeds the guide hole 11, the glue pours downward onto the surface of the decorative board. This design ensures that the glue can wet the decorative board before adhesion, thereby improving the adhesion effect. The matching relationship between the adjustment cylinder 12 and the clamping groove 9 ensures the stability of the glue injection process, and is also convenient for disassembly and maintenance.

[0032] The structures of the connecting mechanism 5 and the limiting mechanism 6 are as follows: Figure 4 As shown, the connecting mechanism 5 includes a first connecting tube 16, a second connecting tube 17, and an assembly plate 18, and the limiting mechanism 6 includes a limiting outer ring 19 and an inner clip 20. The upper end surfaces of the first connecting tube 16 and the second connecting tube 17 are vertically inserted into the inner cavity of the guide hole 11, so that the connecting mechanism 5 and the fixing mechanism 3 form a whole. The assembly plate 18 is set on the inner end surface of the first connecting tube 16, and the second connecting tube 17 is set vertically in the middle position of the assembly plate 18. The limiting mechanism 6 is set between the two groups of first connecting tubes 16, and a base is set at the bottom of the inner cavity wall of the limiting outer ring 19. Inner clips 20 are set vertically on both sides of the upper end surface of the base. In actual operation, when multiple decorative panels need to be installed, the staff blocks the second connecting tube 17, allowing the decorative panels to pass through the four groups of first connecting tubes 16 and enter the inner cavity of a single decorative panel. When only a single decorative panel needs to be installed, the second connecting tube 17 is released, allowing the construction adhesive, auxiliary adhesive and decorative panel to fall directly from the second connecting tube 17 into the single decorative panel. The inner clip 20 of the limiting mechanism 6 clamps the outer end surface of the wall during the movement of the device to ensure the stability of the device during operation.

[0033] The structure of the support unit 1 is as follows Figure 5 As shown, the mounting frame 21 includes an assembly frame and positioning frames arranged on both sides of the outer end surface of the assembly frame. The positioning frames arranged opposite to each other are connected by transverse interpenetrating rods. A series ring is arranged between the two sets of transverse interpenetrating rods, and a positioning cross block is arranged transversely between the assembly frame and the positioning frame. The sliding cross frame 22 includes a frame body and a lower cavity opened in the middle position of the bottom of the frame body. Vertical interpenetrating holes are opened on both sides of the bottom of the frame body, and the frame body is transversely inserted into the inner cavity of the assembly frame. The two ends of the track 23 are fixedly connected to fixed support points. The sliding cross frame 22 slides parallel to the upper end surface of the track 23 with the lower cavity opened as a fulcrum, thereby achieving precise movement of the entire device. The storage tube 24 passes vertically downward through the inner cavity of the series ring. The series ring is stably clamped by the positioning frame and the transverse interpenetrating rods to maintain the stability of the storage tube 24 during installation. The staff places the decorative panel into the inner cavity of the device from the top of the storage tube 24, and the decorative panel is transported to the target position by the movement of the sliding cross frame 22.

[0034] In actual application, the staff first fixes the two ends of the track 23 to the fixed support points on the wall, and adjusts the position of the sliding cross frame 22 so that it is aligned with the target decoration area. Then the decorative panel is placed in the inner cavity of the storage tube 24, and the decorative panel slides down along the storage tube 24 to the inner cavity of the base plate 7 for temporary storage. The staff pours the construction glue into the inner cavity of the regulating cylinder 12. The glue flows into the inner cavity of the base plate 7 after being filtered through the filter 10 and overflows at the guide hole 11, covering the surface of the decorative panel. At the same time, the auxiliary glue is poured into the inner cavity of the glue injection cylinder 14. The glue flows into the inner cavity of the base plate 7 along the glue injection tube 15 and mixes with the construction glue before flowing out. If multiple decorative panels need to be installed, the second connecting tube 17 is blocked so that the decorative panel enters the inner cavity of a single decorative panel through the first connecting tube 16. If only a single decorative panel needs to be installed, the second connecting tube 17 is released so that the construction glue, auxiliary glue and decorative panel fall directly from the second connecting tube 17 into the single decorative panel. During the entire process, the inner clamping piece 20 of the limiting mechanism 6 clamps the outer end surface of the wall to ensure the stability of the device during operation.

[0035] In order to better enable relevant personnel in this technical field to fully understand and implement the present invention, the implementation principle of the present invention is further explained in detail below with reference to a specific application scenario.

[0036] In practical application, first secure the ends of the rails 23 to support points on the wall. Adjust the position of the sliding crossbar 22 to align it with the desired decorative area. Next, place the decorative panel into the device's inner cavity from the top of the mounting tube 24. The panel slides down the tube 24 and into the inner cavity of the base plate 7 for temporary storage. During this process, the mounting tube 24 vertically penetrates the inner cavity of the serial ring, and the positioning brackets and transverse crossbars provide a stable clamping force, ensuring that the mounting tube 24 remains stable during installation.

[0037] Next, the staff pours the construction glue into the inner cavity of the regulating cylinder 12. Because the bottom of the regulating cylinder 12 is inserted and fitted into the inner cavity of the snap-in groove 9, the glue flows along the snap-in groove 9 and is filtered through the filter 10 before entering the inner cavity of the base plate 7. When the glue liquid level exceeds the guide hole 11, the glue flows out through the guide hole 11 and covers the surface of the decorative board. This design utilizes the concave structure at the bottom of the inner cavity wall of the base plate 7 to allow the glue to diffuse from the center to the surrounding area, thereby ensuring a uniform adhesion layer between the decorative board and the wall. At the same time, auxiliary glue is poured into the inner cavity of the glue injection cylinder 14. The glue flows into the inner cavity of the base plate 7 along the glue injection tube 15 and mixes with the construction glue. The mixed glue accumulates in the inner cavity of the base plate 7. When the liquid level exceeds the guide hole 11, the glue pours downward onto the surface of the decorative board. This design of wetting first and then adhering effectively improves the adhesion between the decorative board and the wall, while ensuring the adequacy and uniformity of the glue supply during the initial installation stage.

[0038] When installing multiple decorative panels, workers block the second connecting tubes 17, allowing the decorative panels to pass through the four sets of first connecting tubes 16 and into the inner cavity of a single decorative panel. When installing only a single decorative panel, the second connecting tubes 17 are released, allowing the construction adhesive, auxiliary adhesive, and decorative panels to fall directly from the second connecting tubes 17 into the single decorative panel. This method ensures precise placement of the decorative panels, avoids material waste, and improves the success rate of installation.

[0039] Throughout the device's operation, the inner clips 20 of the limiting mechanism 6 clamp the outer end face of the wall. These clips are located on either side of the upper end face of the base at the bottom of the inner cavity wall of the limiting outer ring 19. Their vertical arrangement effectively clamps the wall, ensuring the stability of the device during movement. Furthermore, the sliding crossbar 22, using the lower cavity as a fulcrum, slides parallel to the upper end face of the track 23, ensuring precise movement of the entire device.

[0040] Through the above steps, this modular wall decoration device can achieve efficient adaptation to complex wall conditions. The design of the track 23 and sliding crossbeam 22 of the support unit 1 allows the device to be flexibly adjusted to meet the decorative needs of different wall angles and shapes. The coordinated operation of the fixing mechanism 3 and the adjustment mechanism 4 ensures rapid connection and secure adhesion between the decorative panel and the wall, while the design of the connecting mechanism 5 and the limiting mechanism 6 further optimizes the device's construction efficiency and reusability.

[0041] In summary, the present invention solves the problems of insufficient adaptability, poor construction flexibility and complex connection structure existing in the prior art through the reasonable layout and functional coordination of various components, and significantly improves the overall performance of the modular wall decoration device.
