[0002] In the current field of architectural decoration, composite decorative panels have been widely used in the decoration of various places such as internal and external walls, floors and ceilings due to their unique aesthetics and practicality. Composite decorative panels are usually made of multiple materials through a specific process, aiming to provide higher durability, better decorative effects and more economical maintenance costs.

[0003] The patent with publication number CN213868684U discloses a composite decorative panel for building decoration, including a decorative panel body, a high-density board, a card block and a pressure strip. A groove is provided on the top of the decorative panel body, and a pressure strip is fixedly connected to the top of the decorative panel body. The pressure strip is connected to the inside of the groove by inlaying. A card slot is provided on the outside of the groove, and the card block is embedded in the inside of the card slot. The composite decorative panel for building decoration solves the problem that the traditional composite decorative panel has a short service life by providing a groove on the top of the decorative panel body and combining the corresponding pressure strip. The pressure strip is inlaid in the groove between the decorative panel bodies, so that the connection gap between the adjacent decorative panel bodies can be sealed, which greatly improves the sealing performance of the decorative panel when in use. No matter it is moisture or water, it cannot penetrate into the connection of the decorative panel body. The overall structure is simple, easy to install, and the service life is well extended. It is highly practical.

[0004] In the above technical solution, the decorative panel is directly installed on the external wall. When the decorative layer pattern needs to be replaced or the decorative layer is old and not beautiful after long-term use, it is often necessary to disassemble the entire panel, which is relatively cumbersome.

[0005] The present application provides a composite decorative panel, which is used to solve the problem that the decorative panel in the prior art is directly installed on the external wall, and when the decorative panel needs to be replaced, it needs to be completely disassembled, which is relatively cumbersome.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: A composite decorative panel, including: a back panel, a mounting frame, a decorative panel body, a first fixing component, and a second fixing component. The back panel includes a first end face; the mounting frame is arranged around the edge of the first end face, the mounting frame includes a first wall panel and a second wall panel that are arranged oppositely, and a third wall panel and a fourth wall panel that are arranged oppositely, and the mounting frame is formed by connecting the first wall panel, the third wall panel, the second wall panel, and the fourth wall panel in sequence and enclosing them end to end; the decorative panel body is arranged in the mounting frame; the first fixing component includes a plug-in slot, a plug-in plate, a plug-in rod, and a spring, the plug-in slot is provided on the first wall panel and the third wall panel, the notch of the plug-in slot is located on the first wall panel, and the extension direction of the plug-in slot is the same as the extension direction of the third wall panel; the plug-in slot includes a first slot wall, the first slot wall is away from the interior of the mounting frame, a pin hole penetrating the first slot wall is provided on the first slot wall, the pin hole includes a first opening and a second opening that are arranged oppositely, and the first opening faces the interior of the mounting frame;

[0007] The latch rod is slidably arranged in the pin hole in the extension direction of the pin hole; the spring is sleeved on the latch rod and is located in the pin hole; the head of the plug plate has a transition slope; when the board body of the plug plate abuts against the latch rod, the spring is elastically deformed, and the latch rod is passed through the first opening to fix the decorative plate body; when there is a gap between the board body of the plug plate and the latch rod, the latch rod is passed through the second opening, and the end of the latch rod close to the first opening is located in the pin hole; the second fixing component cooperates with the first fixing component to fix the decorative plate body in the installation frame.

[0008] In the embodiment of the present application, the decorative plate body can be detachably fixed by the first fixing component and the second fixing component without the need for overall disassembly. Specifically, the decorative plate body is fixed by the elastic deformation of the latch rod and the spring through the cooperation of the plug slot and the plug plate. When the plug plate is fully plugged into the plug slot, that is, when the body of the plug plate abuts against the latch rod, the spring produces elastic deformation, the latch rod is inserted into the first opening, and abuts against the decorative plate body. The decorative plate body is quickly fixed by the friction between the latch rod and the decorative plate body; when the plug plate is detached from the plug slot, there is a gap between the body of the plug plate and the latch rod, and the spring performs elastic recovery so that the latch rod is inserted into the second opening and has no contact with the decorative plate body, which is conducive to the rapid disassembly of the decorative plate body. In summary, the efficiency of disassembling and replacing the decorative plate body can be improved, the replacement process can be simplified, the problem of cumbersome replacement of existing decorative plates is effectively solved, and the maintainability of the decorative plate is improved.

Since the diameter of the limit ring is larger than the diameter of the first hole segment and the third hole segment, a physical barrier can be formed to prevent the latch rod from excessively moving in the pin hole, ensuring that the latch rod will not move out of the pin hole.

[0010] In some possible implementations, the spring is located between the stop ring and the third hole segment, and the radius of the spring is smaller than the radius of the stop ring and larger than the radius of the third hole segment. In this way, the spring can be stably restrained between the stop ring and the third hole segment, preventing the spring from failing in its reset function due to unreliable assembly, thereby improving the durability of the composite decorative panel. In addition, this can also simplify the assembly process of the spring, allowing the operator to easily assemble the latch rod and the spring into place, thereby improving the efficiency and accuracy of assembly.

When the decorative plate body is installed in the installation frame, each plug-in rod is plugged into the first plug-in hole corresponding thereto.

[0012] In this way, the second fixing assembly has a simple structure and is easy to use. Thus, on the one hand, the efficiency of disassembly and installation of the decorative panel body can be improved; on the other hand, the production process of the composite decorative panel can be simplified, thereby facilitating the large-scale production of the composite decorative panel.

[0013] In some possible implementations, a second plug hole is provided on the decorative plate body at a position corresponding to the pin hole, and when the plate body of the plug plate abuts against the plug rod, the plug rod is plugged into the second plug hole. In this way, physical locking can be achieved, which can effectively prevent the decorative plate body from moving or falling off due to external forces, and improve the stability of the decorative plate body.

[0014] In some possible implementations, there are multiple pin holes, latch rods, and springs, multiple pin holes are arranged in one-to-one correspondence with multiple latch rods, each latch rod is arranged in its corresponding pin hole, multiple springs are arranged in one-to-one correspondence with multiple latch rods, multiple springs are arranged in one-to-one correspondence with multiple pin holes, each spring is sleeved on its corresponding latch rod and located in its corresponding pin hole. In this way, multi-point fixation can be performed, which can improve the stability of the fixation of the decorative plate body.

[0015] In some possible implementations, the plug plate is an elastic member; a pull-out groove is provided on the surface of the third wall plate and the back plate, and the pull-out groove is connected to the plug-in groove; the composite decorative panel further includes a sealing cover, which is used to cover the pull-out groove.

[0035] The back plate 1 includes a first end surface 11; the first end surface 11 is the surface of the back plate 1 facing away from other objects. The mounting frame 2 is arranged around the edge of the first end surface 11. The mounting frame 2 and the back plate 1 can be fixedly connected by screw connection, clamping, bonding, welding, etc.; or the mounting frame 2 and the back plate 1 are integrally formed.

[0036] The installation frame 2 includes a first wall panel 21 and a second wall panel 22 that are arranged opposite to each other, and a third wall panel 23 and a fourth wall panel 24 that are arranged opposite to each other. The installation frame 2 is formed by connecting the first wall panel 21, the third wall panel 23, the second wall panel 22, and the fourth wall panel 24 in sequence end to end and enclosing each other; the decorative panel body 3 is arranged in the installation frame 2.

[0037] See also Figure 3 Combined with Figure 4 and Figure 5The first fixing assembly 4 includes a plug-in slot 41, a plug-in plate 42, a latch rod 43, and a spring 44. The plug-in slot 41 is provided on the first wall plate 21 and the third wall plate 23. The notch of the plug-in slot 41 is located on the first wall plate 21, and the extension direction of the plug-in slot 41 is the same as the extension direction of the third wall plate 23. Exemplarily, the first wall plate 21 can be the top plate of the mounting frame 2. Of course, the present application is not limited thereto. In other embodiments, the first wall plate 21 can also be the bottom plate of the mounting frame 2. In this case, the friction between the plug-in plate 42 and the plug-in slot 41 can be used to overcome the weight of the plug-in plate 42 itself, or the plug-in plate 42 can be detachably connected to the mounting frame 2 through other structures to overcome the weight of the plug-in plate 42 itself.

[0038] See also Figure 5 Combined with Figure 6 The plug-in slot 41 includes a first slot wall 411, which faces away from the interior of the installation frame 2. A pin hole 412 is formed on the first slot wall 411 and penetrates the first slot wall 411. The pin hole 412 includes a first opening 4124 and a second opening 4125 that are arranged opposite to each other. The first opening 4124 faces the interior of the installation frame 2.

[0039] The latch rod 43 is slidably arranged in the pin hole 412 in the extension direction of the pin hole 412; the spring 44 is sleeved on the latch rod 43 and is located in the pin hole 412; the head of the plug plate 42 has a transition slope 421; when the body of the plug plate 42 abuts against the latch rod 43, the spring 44 is elastically deformed, and the latch rod 43 is inserted into the first opening 4124 to fix the decorative plate body 3; when there is a gap between the body of the plug plate 42 and the latch rod 43, the latch rod 43 is inserted into the second opening 4125, and the end of the latch rod 43 close to the first opening 4124 is located in the pin hole 412; the second fixing component 5 cooperates with the first fixing component 4 to fix the decorative plate body 3 in the installation frame 2.

[0040] In this way, the decorative plate body 3 can be detachably fixed by the first fixing component 4 and the second fixing component 5 without the need for overall disassembly. Specifically, the decorative plate body 3 is fixed by the elastic deformation of the latch rod 43 and the spring 44 through the cooperation between the plug slot 41 and the plug plate 42. When the plug plate 42 is fully plugged into the plug slot 41, that is, the body of the plug plate 42 abuts against the latch rod 43, the spring 44 produces elastic deformation, the latch rod 43 penetrates the first opening 4124 and abuts against the decorative plate body 3, and the decorative plate body 3 is quickly fixed by the friction between the latch rod 43 and the decorative plate body 3; when the plug plate 42 is detached from the plug slot 41, there is a gap between the body of the plug plate 42 and the latch rod 43, and the spring 44 performs elastic recovery so that the latch rod 43 penetrates the second opening 4125 and has no contact with the decorative plate body 3, which is conducive to the rapid disassembly of the decorative plate body. In summary, the efficiency of disassembling and replacing the decorative panel body 3 can be improved, the replacement process can be simplified, the problem of cumbersome replacement of existing decorative panels can be effectively solved, and the maintainability of the decorative panels can be improved.

[0041] See also Figure 3 Combined with Figure 4 In some embodiments, the second fixing assembly 5 includes a plurality of plug-in rods 51, which are arranged on the surface of the decorative plate body 3 facing the fourth wall plate 24, and a plurality of first plug-in holes 52 are provided on the fourth wall plate 24, and the plurality of first plug-in holes 52 are arranged one by one corresponding to the plurality of plug-in rods 51. When the decorative plate body 3 is installed in the installation frame 2, each plug-in rod 51 is plugged into the first plug-in hole 52 corresponding thereto. Here, "plurality" means greater than or equal to two.

[0042] In this way, the second fixing component 5 has a simple structure and is easy to use. In this way, on the one hand, the disassembly and installation efficiency of the decorative panel body 3 can be improved; on the other hand, the production process of the composite decorative panel can be simplified, thereby facilitating the large-scale production of the composite decorative panel. Of course, the present application is not limited to this. In other embodiments, the plug-in rod 51 can be provided on the fourth wall panel 24, and the first plug-in hole 52 can be provided on the decorative panel body 3. In some other embodiments, the first fixing component 4 and the second fixing component 5 can have the same structure. The first fixing component 4 and the second fixing component 5 are symmetrically arranged about the central axis of the mounting frame 2.

[0043] See also Figure 5 Combined with Figure 6In some embodiments, the pin hole 412 includes a first hole segment 4121, a second hole segment 4122, and a third hole segment 4123. The second hole segment 4122 is located between the first hole segment 4121 and the third hole segment 4123. The first hole segment 4121 has a second opening 4125. The radius of the second hole segment 4122 is greater than the radius of the first hole segment 4121 and the radius of the third hole segment 4123. A limiting ring 431 is provided on the rod body of the latch rod 43 located in the second hole segment 4122. Specifically, the limiting ring 431 and the latch rod 43 are an integrally formed part. It is understandable that in other embodiments, the limiting ring 431 and the latch rod 43 can also be fixed by bonding or the like. The radius of the limiting ring 431 is greater than the radius of the first hole segment 4121 and the radius of the third hole segment 4123. Since the diameter of the limiting ring 431 is larger than the diameters of the first hole section 4121 and the third hole section 4123 , a physical barrier can be formed to prevent the latch rod 43 from excessively moving in the pin hole 412 , thereby ensuring that the latch rod 43 does not move out of the pin hole 412 .

[0044] See also Figure 5 In some embodiments, the spring 44 is located between the limiting ring 431 and the third hole segment 4123, and the radius of the spring 44 is smaller than the radius of the limiting ring 431 and larger than the radius of the third hole segment 4123. In this way, the spring 44 can be stably limited between the limiting ring 431 and the third hole segment 4123, preventing the reset function of the spring 44 from failing due to unreliable assembly, thereby improving the durability of the composite decorative panel. In addition, this can also simplify the assembly process of the spring 44, so that the operator can easily combine the latch rod 43 and the spring 44 in place, thereby improving the efficiency and accuracy of assembly. Of course, the present application is not limited thereto. In other embodiments, the spring 44 can also be located between the limiting ring 431 and the first hole segment 4121, one end of the spring 44 is fixedly connected to the limiting ring 431, and the other end is fixedly connected to the inner wall surface of the second hole segment 4122. In some other embodiments, the limiting ring 431 can also be not provided, and one end of the spring 44 can be fixedly connected to the latch rod 43 and the inner wall surface of the pin hole 412.

[0045] For example, in Figure 5 In the illustrated embodiment, the number of the pin hole 412, the latch rod 43, and the spring 44 are all one. Of course, the present application is not limited thereto. In other embodiments, the number of the pin hole 412, the latch rod 43, and the spring 44 can also be multiple, multiple pin holes 412 are arranged in a one-to-one correspondence with multiple latch rods 43, each latch rod 43 is arranged in its corresponding latch hole 412, multiple springs 44 are arranged in a one-to-one correspondence with multiple latch rods 43, multiple springs 44 are arranged in a one-to-one correspondence with multiple pin holes 412, and each spring 44 is sleeved on its corresponding latch rod 43 and located in its corresponding latch hole 412. In this way, multi-point fixation can be performed, which can improve the stability of the fixation of the decorative plate body 3.

[0046] See also Figure 5 In some embodiments, a second plug hole 31 is provided on the decorative plate body 3 at a position corresponding to the pin hole 412. When the body of the plug plate 42 abuts against the plug rod 43, the plug rod 43 is plugged into the second plug hole 31. In this way, physical locking can be achieved, which can effectively prevent the decorative plate body 3 from moving or falling off due to external force, and improve the stability of the fixing of the decorative plate body 3.

[0047] See also Figure 7 In some embodiments, the plug plate 42 is an elastic member; a pull-out groove 231 is provided on the surface where the third wall plate 23 and the back plate 1 are stacked, and the pull-out groove 231 is connected to the plug-in groove 41; the composite decorative plate further includes a sealing cover 2311, and the sealing cover 2311 is used to cover the pull-out groove 231. Exemplarily, the sealing cover 2311 can be detachably fixedly connected to the installation frame 2, or can be rotatably connected to the third wall plate 23 through the cooperation of the rotating shaft and the shaft hole, and the rotation center line of the sealing cover 2311 is parallel to the extension direction of the third wall plate 23.

[0048] In this way, when multiple composite decorative panels are used in combination and the slot of the plug-in slot 41 on the first wall panel 21 is closed, the sealing cover 2311 can be opened to expose the pull-out slot 231, and the plug-in plate 42 can be pulled out by utilizing its elasticity to achieve disassembly of the decorative panel body 3.

[0049] See also Figure 8 In some embodiments, the decorative board body 3 includes: a board body 32, a thermal insulation layer 33 is arranged on the surface of the board body 32; a corrosion-resistant layer 34 is arranged on the surface of the thermal insulation layer 33; and a wear-resistant layer 37 is arranged on the surface of the corrosion-resistant layer 34. Exemplarily, the thermal insulation layer 33 can be a rock wool thermal insulation board or a hard foam polyurethane part. The corrosion-resistant layer 34 can be an epoxy acrylic resin part. The wear-resistant layer 37 can be a polyvinyl chloride resin part or an epoxy resin wear-resistant coating. In this way, the comprehensive performance of the decorative board body 3 can be improved, and the practicality and durability of the decorative board can be enhanced.

[0050] See also Figure 8 In some embodiments, a sound insulation layer 35 is provided between the corrosion-resistant layer 34 and the wear-resistant layer 37. For example, the sound insulation layer 35 may be a polyester fiber sound-absorbing board. In this way, the sound insulation effect of the decorative board body 3 may be improved, and the practicality of the decorative board may be further enhanced.

[0051] See also Figure 8 In some embodiments, a waterproof layer 36 is provided between the sound insulation layer 35 and the wear-resistant layer 37. For example, the waterproof layer 36 may be pearl cotton or a waterproof breathable membrane. In this way, the waterproof effect of the decorative board body 3 can be improved, and the practicality and durability of the decorative board can be enhanced.

[0052] It is necessary to explain that Figure 1 The method of using the system of the embodiment shown is as follows: fix the back panel 1 on an object such as a wall, a desktop or a wardrobe surface. Then, the plug rod 51 on the decorative panel body 3 cooperates with the first plug hole 52 on the fourth wall plate 24 of the installation frame 2 to preliminarily fix the decorative panel body 3. Then, the decorative panel body 3 is fixed by the plug slot 41, the plug plate 42, the plug rod 43 and the spring 44 in the first fixing component 4 through the insertion of the plug plate 42, the elastic deformation of the spring 44 and the second plug hole 31.

[0053] During the disassembly process, the plug plate 42 is first pulled out to separate it from the latch rod 43, the spring 44 returns to its original state, and the latch rod 43 switches from being inserted in the first opening 4124 to being inserted in the second opening 4125. Next, the constraint of the second fixing component 5 is released, that is, the plug rod 51 on the decorative plate body 3 is pulled out from the first plug hole 52 of the fourth wall plate 24, thereby releasing the decorative plate body 3. If the notch of the plug slot 41 is closed, the pull-out slot 231 can be exposed by opening the sealing cover 2311, and the plug plate 42 can be pulled out by utilizing the elasticity of the plug plate 42 to realize the disassembly of the decorative plate body 3.

[0054] The above describes the utility model and its implementation methods, which is not restrictive. What is shown in the full text is only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
