Description

Technical Field

[0001] This invention relates to the field of wall panel technology, specifically to an environmentally friendly, low-carbon, stone-wood-plastic composite prefabricated wall panel. Background Technology

[0002] Wall panels are an important part of interior decoration. They are mainly made of materials such as PVC, polymer, wood-plastic, stone-plastic, calcium silicate board, and MDF. In recent years, with the popularization of the concept of environmentally friendly decoration, environmentally friendly and low-carbon stone-wood-plastic wall panels have been widely used.

[0003] Traditional wall panel installation methods typically involve installers cutting the panels on-site and smoothing the edges. Since wall panels are usually installed on walls, and the aesthetics of the front of the panels need to be ensured after installation, interlocking fasteners need to be installed on the wall and the back of the panels beforehand.

[0004] However, wall panels typically have a large installation area. Installing fasteners on the back of the entire wall panel would be cumbersome, inefficient, and time-consuming. Summary of the Invention

[0005] The purpose of this invention is to provide an environmentally friendly, low-carbon, stone-wood-plastic prefabricated wall panel to solve the technical problems of cumbersome installation and long construction time in the existing wall panel technology.

[0006] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0007] An environmentally friendly, low-carbon, stone-wood-plastic prefabricated wall panel includes a wall panel body and fasteners. Several wall panel bodies are laid along the wall surface, and the fasteners are located between the wall surface and the wall panel bodies. The wall panel bodies are connected to the wall surface and adjacent wall panel bodies through the fasteners.

[0008] The wall panel body has a slot on its side. The fastener includes an installation plate that is set between two adjacent wall panel bodies. The two sides of the installation plate engage with the two slots on both sides to make the adjacent wall panel bodies splice into one piece.

[0009] The mounting plate is connected to the wall via a connecting plate and a fixing plate. The mounting plate and the connecting plate are connected perpendicularly. The connecting plate is placed in the gap between two adjacent wall panel bodies. The connecting plate and the fixing plate are connected perpendicularly. The fixing plate is placed in the gap between the wall panel body and the wall surface and is fixedly connected to the wall surface.

[0010] Furthermore, an extension plate is fixedly connected to one side of the fixing plate, and a groove is provided on the side of the extension plate near the wall panel body. The groove is provided with fixing nails for fixing the clips, so that the fixing nails do not protrude from the fixing plate.

[0011] Furthermore, a sealing plate is provided between the wall panel body near the side wall and the side wall, and a connecting structure for connecting the sealing plate and the wall panel body is provided between the sealing plate and the adjacent wall panel body, and a supporting structure for connecting the sealing plate and the back wall is provided between the sealing plate and the back wall.

[0012] The connection structure includes a first clamping plate and a second clamping plate. The first clamping plate is fixedly connected to the side of the sealing plate near the wall panel body, and the second clamping plate is hinged to the side of the wall panel body near the sealing plate.

[0013] The support structure includes a female buckle fixedly connected to the back wall and a male buckle disposed on the back of the sealing plate, as well as a telescopic rod fixedly connected between the male buckle and the sealing plate;

[0014] When the sealing plate moves towards the back, the first clamping plate applies a backward pressing force to the second clamping plate, causing the second clamping plate to rotate towards the wall panel body until the male and female buckles engage, completing the connection between the sealing plate and the back wall. At the same time, the first clamping plate passes over the second clamping plate, eliminating the pressing force on the second clamping plate, allowing the second clamping plate to return to its initial state and drive the sealing plate to move towards the front. The telescopic rod is then stretched to support the sealing plate, and the first and second clamping plates mutually limit each other.

[0015] Furthermore, a limiting groove is provided on the front side of the first card plate, and a limiting block is fixedly connected to the back of the second card plate;

[0016] When the sealing plate moves towards the back, it causes the second card plate to rotate towards the wall panel body, thereby placing the limiting block in the corresponding slot. After the first card plate passes the second card plate, the second card plate returns to its original state. Then, the sealing plate moves towards the front until the limiting block is engaged in the limiting slot, completing the installation of the sealing plate and realizing the limiting block's limitation on the first card plate.

[0017] Furthermore, the telescopic rod includes a sleeve fixedly connected to the male buckle and a connecting rod disposed inside the sleeve and fixedly connected to the sealing plate. At least one side of the inner wall of the sleeve is fixedly connected with a plurality of first limiting teeth. The connecting rod is fixedly connected with a plurality of second limiting teeth at positions corresponding to the first limiting teeth. The plurality of second limiting teeth are concentrated at the end of the connecting rod away from the sealing plate. The first limiting teeth are provided with a downward inclined first inclined surface on the side near the connecting rod, and the second limiting teeth are provided with an upward inclined second inclined surface on the side near the sleeve.

[0018] In the initial state, all the connecting rods are set inside the sleeve. When the connecting rods are subjected to a forward external force, the second limiting tooth squeezes the first limiting tooth to deform it, thereby continuously moving forward past the first limiting tooth until the front side of the sealing plate and the front side of the wall panel body are on the same horizontal plane. At the same time, the first limiting tooth restricts the second limiting tooth from moving backward.

[0019] Furthermore, the female buckle includes a fixing frame with an opening on the front side, and the male buckle includes a connecting block fixedly connected to the sleeve and an insert block fixedly connected to the back of the connecting block, with deformation blocks fixedly connected to both sides of the insert block;

[0020] After the insert block enters the fixed frame through the opening, it continues to be pressed backward, causing the deformable block to deform and enter the fixed frame. Afterward, the deformable block returns to its original shape, and the side walls of the fixed frame on both sides of the opening limit the deformable block.

[0021] Furthermore, the diameter of the end of the insert near the sleeve is larger than the diameter of the end away from the sleeve, and the diameters of both ends of the insert are smaller than the opening diameter.

[0022] Furthermore, the vertical cross-section of the deformable block is set to a fan shape, one side of the deformable block is on the same horizontal plane as the front side of the insert block, the other side of the deformable block is in contact with the outer surface of the insert block, and the deformable block is made of elastic material.

[0023] Furthermore, there are blocks on both sides inside the fixed frame. The blocks are in close contact with the front side of the inner wall of the fixed frame, and a return spring is fixedly connected between the blocks and the inner wall of the fixed frame.

[0024] When the insert block is inserted into the fixed frame, it compresses the stop block, causing the return spring to be compressed. After the insert block passes the stop block, the return spring rebounds, causing the stop block to move towards the connecting block, thereby limiting the insert block and preventing it from moving forward. At this time, the back of the sleeve is in close contact with the front side of the fixed frame, restricting the insert block from moving backward.

[0025] Furthermore, a slider is fixedly connected to the front side of the stop block, and a groove is provided on the front side of the inner wall of the fixed frame. The slider slides left and right inside the groove, thereby limiting the movement direction of the stop block.

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

[0027] This invention uses clips to snap two wall panels onto both sides of the clips to complete the installation. This eliminates the need to install fasteners on the back of the wall panels or on the wall where the panels are to be installed, making the construction simple and avoiding extensive damage to the original wall surface, thus improving installation efficiency.

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Traditional wall panel installation methods typically involve on-site cutting and smoothing of the panels by installers. Since wall panels are usually installed on a wall, and the aesthetics of the front of the panel after installation need to be ensured, interlocking fasteners must be installed on the wall surface and the back of the panel beforehand. However, wall panels generally cover a large area, and installing fasteners on the entire back of the panel is cumbersome and inefficient. Therefore, developing a wall panel that is easy to install is essential.

[0043] like Figure 1 As shown, the present invention provides an environmentally friendly, low-carbon stone-wood-plastic prefabricated wall panel, which is mainly installed by using a clip 2 to clip two wall panel bodies 1 onto both sides of the clip 2.

[0044] The environmentally friendly and low-carbon stone-wood-plastic prefabricated wall panel includes a wall panel body 1 and a fastener 2. Several wall panel bodies 1 are laid along the wall surface, and the fastener 2 is located between the wall surface and the wall panel body 1. The wall panel body 1 is connected to the wall surface and the adjacent wall panel body 1 through the fastener 2.

[0045] The wall panel body 1 has a slot 204 on its side. The fastener 2 includes an installation plate 201 disposed between two adjacent wall panel bodies 1. The two sides of the installation plate 201 are engaged with the two slots 204 on both sides so that the adjacent wall panel bodies 1 are spliced ​​together as one unit.

[0046] Mounting plate 201 is connected to the wall via connecting plate 203 and fixing plate 202. Mounting plate 201 and connecting plate 203 are vertically connected. Connecting plate 203 is set in the gap between two adjacent wall panel bodies 1. Connecting plate 203 and fixing plate 202 are vertically connected. Fixing plate 202 is set in the gap between wall panel body 1 and the wall and is fixedly connected to the wall.

[0047] This embodiment uses a clip 2 to snap the two wall panel bodies 1 onto both sides of the clip 2 to complete the installation. It eliminates the need to install fasteners on the back of the wall panel or on the wall where the wall panel needs to be installed, making the construction simple and avoiding large-scale damage to the original wall surface, thus improving installation efficiency.

[0048] Step 1: Install clip 2, fix the fixing plate 202 to the wall where the wall panel needs to be installed by fixing nail 207, complete the fixing of clip 2, and make clip 2 perpendicular to the ground;

[0049] Step 2: Place the wall panel body 1, placing the wall panel body 1 to be installed on both sides of the clip 2;

[0050] Step 3: Install the wall panel body 1, so that the slot 204 on the wall panel body 1 engages with the mounting plate 201 on the clip 2, so that the mounting plate 201 limits the front and rear direction of the wall panel body 1, and the installation of the wall panel body 1 is completed.

[0051] If the fixing plate 202 is directly fixed to the wall, the fixing nail 207 will protrude from the fixing plate 202, affecting the installation of the wall panel body 1. In order to solve this problem, the present invention provides the following preferred embodiment: an extension plate 205 is fixedly connected to one side of the fixing plate 202, and a groove 206 is provided on the side of the extension plate 205 near the wall panel body 1. The groove 206 is provided with fixing nails 207 for fixing the clip 2, so that the fixing nails 207 will not protrude from the fixing plate 202.

[0052] In actual use, the fixing nail 207 is fixed in the groove 206 on the extension plate 205, which is convenient for construction. At the same time, the nail head of the fixing nail 207 will not protrude and will not affect the installation of the wall panel body 1, so that the front side of the wall panel body 1 after installation is on the same horizontal plane.

[0053] In actual construction, the walls on both sides of the wall to be installed are often also walls. Since the wall panel body 1 is of a fixed size, after the wall panel body 1 is installed close to one side of the wall, there will be a gap between the other side of the wall and the installed wall panel body 1. Even if the wall panel body 1 can be cut, when installing the last wall panel body 1, in order to make the connection between the last two wall panel bodies 1 more secure, it is also necessary to snap the slot 204 on the wall panel body 1 with the installation plate 201.

[0054] like Figure 6 As shown, if the size of the last wall panel body 1 matches the reserved spacing perfectly, so that there is no gap between the last wall panel body 1 and the adjacent wall panel body 1, then due to the presence of the mounting plate 201, the last wall panel body 1 cannot be snapped into the mounting plate 201 to complete the installation.

[0055] like Figure 7 As shown, if the size of the last wall panel body 1 is made too small in order to snap it into the mounting plate 201 for installation, then after the installation is completed, there will still be a gap between the last wall panel body 1 and the side wall, making the wall panel body 1 not securely installed and not aesthetically pleasing.

[0056] Therefore, securely installing the last wall panel body 1 of suitable size within the spacing is currently an unsolvable problem. To address this, the present invention provides the following preferred embodiment: Figure 2 As shown, a sealing plate 3 is provided between the wall panel body 1 near the side wall and the side wall. A connecting structure 4 for connecting the sealing plate 3 and the wall panel body 1 is provided between the sealing plate 3 and the adjacent wall panel body 1. A support structure for connecting the sealing plate 3 and the back wall is provided between the sealing plate 3 and the back wall. The sealing plate 3 is connected to the back wall through the support structure, and the sealing plate 3 is connected to the adjacent wall panel body 1 through the connecting structure 4.

[0057] The connection structure 4 includes a first card plate 401 and a second card plate 402. The first card plate 401 is fixedly connected to the side of the sealing plate 3 near the wall panel body 1, and the second card plate 402 is hinged to the side of the wall panel body 1 near the sealing plate 3.

[0058] The support structure includes a female buckle 501 fixedly connected to the back wall and a male buckle 502 disposed on the back of the sealing plate 3, as well as a telescopic rod 503 fixedly connected between the male buckle 502 and the sealing plate 3.

[0059] When the sealing plate 3 moves towards the back, the first clamping plate 401 applies a backward pressing force to the second clamping plate 402, causing the second clamping plate 402 to rotate towards the wall panel body 1 until the male buckle 502 and the female buckle 501 are engaged, completing the connection between the sealing plate 3 and the back wall. At the same time, the first clamping plate 401 passes over the second clamping plate 402, eliminating the pressing force on the second clamping plate 402, allowing the second clamping plate 402 to return to its initial state, and driving the sealing plate 3 to move towards the front. The telescopic rod 503 is then stretched to support the sealing plate 3, and the first clamping plate 401 and the second clamping plate 402 mutually limit each other.

[0060] In practical use, when the distance between the last installed wall panel body 1 and the side wall is less than the width of a whole wall panel body 1, the second clip 402 is fixed to the side of the last wall panel body 1 near the side wall via a hinge. The sealing plate 3 is then cut on-site to fit the distance, i.e., the width after the first clip 401 and the second clip 402 are engaged. The female buckle 501 is first fixed to the wall on the back of the sealing plate 3 using adhesive or fixing nails. The male buckle 502 and the telescopic rod 503 are then fixed to the back of the sealing plate 3, corresponding to the female buckle 501. At the corresponding position, the sealing plate 3 is held in place by an external suction cup, causing it to move towards the back. At this time, the second clamping plate 402 rotates towards the wall panel body 1 under the pressure of the first clamping plate 401. As the sealing plate 3 continues to move towards the back, when it moves towards the female buckle 501 under external force, the male buckle 502 and female buckle 501 are engaged. Simultaneously, the sealing plate 3 passes over the second clamping plate 402, after which the second clamping plate 402 returns to its original position, and the sealing plate 3 moves forward, causing the telescopic rod 503 to extend. The telescopic rod 503 provides support for the sealing plate 3, completing the installation of the sealing plate 3. Due to the limiting effect of the first clamping plate 401 and the second clamping plate 402, the sealing plate 3 and the adjacent wall panel body 1 are limited.

[0061] Relying solely on the first card plate 401 and the second card plate 402 to connect the sealing plate 3 and the adjacent wall panel body 1 provides insufficient support and connection for both. To further address this issue, such as... Figure 2 As shown, the first card plate 401 has a limiting groove 403 on its front side, and the second card plate 402 has a limiting block 404 fixedly connected to its back.

[0062] When the sealing plate 3 moves towards the back, the second card plate 402 rotates towards the wall panel body 1, thereby placing the limiting block 404 in the corresponding slot 204. After the first card plate 401 passes the second card plate 402, the second card plate 402 returns to its original state. Then, the sealing plate 3 moves towards the front until the limiting block 404 is engaged in the limiting groove 403, completing the installation of the sealing plate 3 and realizing the limiting block 404 limiting the first card plate 401.

[0063] In actual use, when the second card plate 402 rotates towards the wall panel body 1, the limiting block 404 is placed in the corresponding card slot 204. When the sealing plate 3 moves forward, the limiting block 404 is engaged in the limiting groove 403, thereby improving the connection between the first card plate 401 and the second card plate 402.

[0064] Although the telescopic rod 503 supports the sealing plate 3, the sealing plate 3 still experiences inward concavity when subjected to external pressure. If the telescopic rod 503 could be stretched but not compressed even under external force, the above problem could be solved. However, ensuring that the telescopic rod 503 can only be stretched and not compressed is the key challenge. Therefore, this invention provides the following preferred embodiment: Figure 5 As shown.

[0065] The telescopic rod 503 includes a sleeve 504 fixedly connected to the male buckle 502 and a connecting rod 505 disposed inside the sleeve 504 and fixedly connected to the sealing plate 3. At least one side of the inner wall of the sleeve 504 is fixedly connected to a plurality of first limiting teeth 506. The connecting rod 505 is fixedly connected to a plurality of second limiting teeth 507 at positions corresponding to the first limiting teeth 506. The plurality of second limiting teeth 507 are concentrated at the end of the connecting rod 505 away from the sealing plate 3. The first limiting teeth 506 are provided with a downward inclined first inclined surface on the side near the connecting rod 505, and the second limiting teeth 507 are provided with an upward inclined second inclined surface on the side near the sleeve 504.

[0066] In the initial state, all the connecting rods 505 are located inside the sleeve 504. When the connecting rods 505 are subjected to a forward external force, the second limiting tooth 507 squeezes the first limiting tooth 506 to deform it, thereby continuously moving forward past the first limiting tooth 506 until the front side of the sealing plate 3 and the front side of the wall panel body 1 are on the same horizontal plane. At the same time, the first limiting tooth 506 restricts the second limiting tooth 507 from moving backward.

[0067] By providing a first limiting tooth 506 and a second limiting tooth 507, in the initial state, the connecting rod 505 is entirely located inside the sleeve 504, which shortens the distance between the sealing plate 3 and the male buckle 502. This allows the sealing plate 3 to completely pass over the second clamping plate 402 when the male buckle 502 is connected to the female buckle 501, without affecting the second clamping plate 402 returning to its original position. When the sealing plate 3 is pulled forward, due to the presence of the first and second inclined surfaces, the connecting rod 505 can move forward simply by deforming the first limiting tooth 506 and the second limiting tooth 507. When the sealing plate 3 is subjected to a backward compressive force, the presence of the first limiting tooth 506 restricts the connecting rod 505 from moving backward, thereby supporting the sealing plate 3 and preventing the sealing plate 3 from denting.

[0068] The following provides a detailed explanation of the specific structures of male snap fastener 502 and female snap fastener 501. For example... Figure 4 and Figure 5 As shown, the female buckle 501 includes a fixing frame 508, and the fixing frame 508 has an opening 509 on the front side. The male buckle 502 includes a connecting block 510 fixedly connected to the sleeve 504 and an insert block 511 fixedly connected to the back of the connecting block 510. Deformation blocks 512 are fixedly connected to both sides of the insert block 511.

[0069] When the insert block 511 enters the fixed frame 508 through the opening 509, and the insert block 511 is pressed backward, the deformable block 512 deforms and enters the fixed frame 508. After that, the deformable block 512 returns to its original shape, and the side walls of the fixed frame 508 on both sides of the opening 509 limit the deformable block 512.

[0070] When the sealing plate 3 moves backward, the insert block 511 first enters the fixed frame 508 through the opening 509. As the sealing plate 3 moves backward, the inner wall of the opening 509 squeezes the deformable block 512, causing it to deform and enter the fixed frame 508. Afterward, the deformable block 512 loses the squeezing force of the inner wall of the opening 509 and returns to its original shape. Then, the inner wall of the opening 509 limits the deformable block 512, preventing the insert block 511 from detaching from the fixed frame 508.

[0071] To facilitate faster insertion of the insert 511 into the fixing frame 508, the diameter of the end of the insert 511 closest to the sleeve 504 is larger than the diameter of the end furthest from the sleeve 504, and the diameters of both ends of the insert 511 are smaller than the diameter of the opening 509. This makes it easier for the male buckle 502 and the female buckle 501 to engage, simplifying the operation and saving installation time.

[0072] To make the insertion of the deformable block 512 into the fixing frame 508 smoother, such as Figure 5As shown, the deformable block 512 has a fan-shaped vertical cross-section. One side of the deformable block 512 is on the same horizontal plane as the front side of the insert block 511, and the other side of the deformable block 512 is in contact with the outer surface of the insert block 511. The deformable block 512 is made of an elastic material. This fan-shaped outer surface of the deformable block 512 makes it easier to enter the opening 509.

[0073] In order to make the fixing frame 508 more secure in limiting the insertion block 511 and prevent the sealing plate 3 from shaking back and forth, the fixing frame 508 is further provided with a stop block 513 on both sides inside. The stop block 513 is close to the front side of the inner wall of the fixing frame 508, and a return spring 514 is fixedly connected between the stop block 513 and the inner side wall of the fixing frame 508.

[0074] When the insert 511 is inserted into the fixed frame 508, it presses the stop 513, which compresses the return spring 514. After the insert 511 passes the stop 513, the return spring 514 rebounds, causing the stop 513 to move towards the connecting block 510, thereby limiting the insert 511 and preventing it from moving forward. At this time, the back of the sleeve 504 is close to the front of the fixed frame 508, restricting the insert 511 from moving backward.

[0075] The rebound force of the return spring 514 automatically moves the stop block 513 between the insert block 511 and the inner wall of the fixing frame 508, limiting the insert block 511 and preventing it from moving backward. At the same time, the back of the sleeve 504 is close to the front of the fixing frame 508, restricting the insert block 511 from moving backward and improving the fixing effect of the insert block 511.

[0076] The stop block 513 moves left and right under the pressure of the insert block 511 and the rebound force of the return spring 514. However, during the left and right movement, the stop block 513 may deviate in the up and down and forward and backward directions. To solve this problem, this embodiment provides a specific solution: a slider 515 is fixedly connected to the front side of the stop block 513, and a groove 516 is provided on the front side of the inner wall of the fixed frame 508. The slider 515 slides left and right inside the groove 516, thereby limiting the movement direction of the stop block 513. By providing the slider 515 and the groove 516, the movement of the stop block 513 can be limited, improving the stability of the stop block 513's movement.

A fixing nail (207) for fixing the clip (2) is provided inside the groove (206) so that the fixing nail (207) will not protrude from the fixed plate (202). A sealing plate (3) is provided between the wall panel body (1) near the side wall and the side wall. A connecting structure (4) for connecting the sealing plate (3) and the wall panel body (1) is provided between the sealing plate (3) and the adjacent wall panel body (1). A supporting structure for connecting the sealing plate (3) and the back wall is provided between the sealing plate (3) and the back wall. The connection structure (4) includes a first card plate (401) and a second card plate (402). The first card plate (401) is fixedly connected to the sealing plate (3) on the side near the wall panel body (1), and the second card plate (402) is hinged to the wall panel body (1) on the side near the sealing plate (3). The support structure includes a female buckle (501) fixedly connected to the back wall and a male buckle (502) set on the back of the sealing plate (3), as well as a telescopic rod (503) fixedly connected between the male buckle (502) and the sealing plate (3). When the sealing plate (3) moves toward the back, the first clamping plate (401) applies a backward pressing force to the second clamping plate (402), causing the second clamping plate (402) to rotate toward the wall panel body (1) until the male buckle (502) and the female buckle (501) are engaged, completing the connection between the sealing plate (3) and the back wall. At the same time, the first clamping plate (401) passes over the second clamping plate (402) and eliminates the pressing force on the second clamping plate (402), allowing the second clamping plate (402) to return to its initial state and drive the sealing plate (3) to move toward the front. The telescopic rod (503) is stretched to support the sealing plate (3), and the first clamping plate (401) and the second clamping plate (402) limit each other.

2. The environmentally friendly, low-carbon stone-wood-plastic prefabricated wall panel according to claim 1, characterized in that, The first card plate (401) has a limiting groove (403) on its front side, and the second card plate (402) has a limiting block (404) fixedly connected to its back. When the sealing plate (3) moves to the back, the second card plate (402) rotates towards the wall panel body (1), so that the limiting block (404) is placed in the corresponding slot (204). After the first card plate (401) passes the second card plate (402), the second card plate (402) is restored to its original state. Then the sealing plate (3) moves to the front until the limiting block (404) is engaged in the limiting slot (403), thus completing the installation of the sealing plate (3) and realizing the limiting block (404) limiting the first card plate (401).

3. The environmentally friendly, low-carbon stone-wood-plastic composite prefabricated wall panel according to claim 2, characterized in that, The telescopic rod (503) includes a sleeve (504) fixedly connected to the male buckle (502) and a connecting rod (505) disposed inside the sleeve (504) and fixedly connected to the sealing plate (3). At least one side of the inner wall of the sleeve (504) is fixedly connected with a plurality of first limiting teeth (506). The connecting rod (505) is fixedly connected with a plurality of second limiting teeth (507) at positions corresponding to the first limiting teeth (506). The plurality of second limiting teeth (507) are concentrated at the end of the connecting rod (505) away from the sealing plate (3). The first limiting teeth (506) are provided with a first inclined surface that is inclined downward on the side near the connecting rod (505), and the second limiting teeth (507) are provided with a second inclined surface that is inclined upward on the side near the sleeve (504). In the initial state, all the connecting rods (505) are set inside the sleeve (504). When the connecting rods (505) are subjected to a forward external force, the second limiting tooth (507) squeezes the first limiting tooth (506) to deform it, thereby continuously passing the first limiting tooth (506) and moving forward until the front side of the sealing plate (3) and the front side of the wall panel body (1) are on the same horizontal plane. At the same time, the first limiting tooth (506) restricts the second limiting tooth (507) from moving backward.

4. The environmentally friendly, low-carbon stone-wood-plastic composite prefabricated wall panel according to claim 3, characterized in that, The female buckle (501) includes a fixing frame (508), the fixing frame (508) has an opening (509) on the front side, the male buckle (502) includes a connecting block (510) fixedly connected to the sleeve (504) and an insert block (511) fixedly connected to the back of the connecting block (510), and deformation blocks (512) are fixedly connected to both sides of the insert block (511). When the insert (511) enters the fixed frame (508) through the opening (509), the insert (511) is pressed backward, and the deformable block (512) deforms and enters the fixed frame (508). After that, the deformable block (512) returns to its original shape, and the side walls of the fixed frame (508) on both sides of the opening (509) limit the deformable block (512).

5. The environmentally friendly, low-carbon stone-wood-plastic composite prefabricated wall panel according to claim 4, characterized in that, The diameter of the end of the insert (511) near the sleeve (504) is greater than the diameter of the end away from the sleeve (504), and the diameters of both ends of the insert (511) are smaller than the diameter of the opening (509).

6. The environmentally friendly, low-carbon stone-wood-plastic composite prefabricated wall panel according to claim 5, characterized in that, The vertical cross section of the deformable block (512) is set to a fan shape. One side of the deformable block (512) is on the same horizontal plane as the front side of the insert (511). The other side of the deformable block (512) is attached to the outer surface of the insert (511). The deformable block (512) is made of elastic material.

7. The environmentally friendly, low-carbon stone-wood-plastic composite prefabricated wall panel according to claim 6, characterized in that, Both sides of the fixed frame (508) are provided with a stop block (513). The stop block (513) is close to the front side of the inner wall of the fixed frame (508), and a return spring (514) is fixedly connected between the stop block (513) and the inner side wall of the fixed frame (508). When the insert (511) is inserted into the fixed frame (508), it presses the stop (513), causing the return spring (514) to be compressed. After the insert (511) passes the stop (513), due to the rebound force of the return spring (514), the stop (513) moves towards the connecting block (510), thereby limiting the insert (511) and preventing it from moving forward. At this time, the back of the sleeve (504) is close to the front side of the fixed frame (508), restricting the insert (511) from moving backward.

8.
