Description

Technical Field

[0001] The utility model relates to the technical field of assembled background walls, in particular to an overhead connection structure of a background wall. Background Art

[0002] Background wall has good decorative effect on the wall, and can also play a role in protecting the wall, which is deeply loved by people. The traditional background wall is a kind of home decoration art that decorates the family living room TV, sofa, entrance, bedroom, etc. With its novel conception and advanced technology, it not only meets the decoration needs of consumers, but also reflects the owner's unique artistic aesthetic style, making it a perfect combination of business and art.

[0003] Traditional background walls are made by adding wooden strips and base boards to make them overhead. First, the wooden strips need to be treated with fireproofing and anti-corrosion, and then the base is leveled with wooden strips, and then the boards are sealed to make an overhead layer on the wall. If the design requires a larger overhead layer, the wooden base is not firm and needs to be reinforced. This method is cumbersome to install, time-consuming and labor-intensive, and tests the manual ability of the on-site craftsman, which is not conducive to prefabricated decoration; some background walls are mostly integral structures, which are very inconvenient to transport and disassemble. The integral background walls are not convenient to replace, and the existing background walls are mostly decorative and have a relatively single function, which cannot meet people's needs; when the background wall needs to hang a large board, the base is often welded steel frame to create an overhead base. This method has high labor and material costs, and requires special workers to carry out construction. It is difficult to customize and it is difficult to meet the needs of the owner.

[0004] To solve the above problems, a Chinese patent with application number 202220727911.4 discloses a middle support assembly for a concave-convex background wall. The middle support assembly disclosed above includes a fixing part connected to the wall and an adjusting part connected to the wall panel. The fixing part is provided with an insertion groove, and the adjusting part includes an insertion strip, one end of the insertion strip is inserted into the insertion groove along a direction non-parallel to the wall, and the other end is connected to the wall panel. A Chinese patent with application number 202210323679.2 discloses a concave-convex background wall. The above-disclosed background wall includes a background wall panel and a connecting structure for installing the background wall panel to the wall. The background wall panel includes a main board and a secondary board parallel to each other, and the main board is provided with a TV mounting hole; the connecting structure includes a supporting assembly for connecting the main board and the wall, and a wall-attached assembly for connecting the secondary board and the wall; the wall-attached assembly includes an edge trimming mounting piece, and the edge trimming mounting piece includes a connecting plate connected to the wall, and a secondary insertion plate connected to the connecting plate, and the end of the secondary plate is provided with a secondary groove for inserting the secondary insertion plate.

[0005] In the above-mentioned prior art disclosed, the connection and fixation of the background wall panel to the wall is achieved by the connection cooperation between the fixing part and the adjusting part, and the overhead width of the background wall panel can be changed by adjusting the insertion distance between the adjusting part and the fixing part. However, the adjustable overhead width range in the above-mentioned scheme is relatively small, and when the size of the adjusting part and the fixing part is changed to increase the adjustment width, the connection strength between the adjusting part and the fixing part will be reduced, which may easily cause the connection between the adjusting part and the fixing part to break, thereby causing the background wall panel to fall off.

DETAILED DESCRIPTION

[0027] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-Figure 7 As shown, a background wall overhead connection structure includes a wall 1 and a background wall decorative panel 2 overhead mounted on the wall 1, a plurality of connection structures 3 for connecting the wall 1 and the background wall decorative panel 2 are arranged between the wall 1 and the background wall decorative panel 2, the connection structure 3 includes a fixing member 4 and an adjusting member 5, at least one extension member 6 for increasing the overhead width of the background wall decorative panel 2 is arranged between the fixing member 4 and the adjusting member 5, the fixing member 4 is connected to the wall 1, and the adjusting member 5 is connected to the background wall decorative panel 2; both ends of the extension member 6 are provided with a plug strip 602 respectively connected to the fixing member 4 and a plug groove 601 connected to the adjusting member 5.

[0029] Furthermore, the background wall decorative panel 2 is arranged parallel to the wall 1 , and an overhead space is formed between the background wall decorative panel 2 and the wall 1 . The connecting structure 3 is located in the overhead space, and the background wall decorative panel 2 and the wall 1 are connected and fixed by the connecting structure 3 .

[0030] The adjusting member 5 is movably connected to the fixing member 4. By adjusting the distance between the adjusting member 5 and the wall 1, the distance between the background wall decorative panel 2 and the wall 1 can be adjusted, thereby realizing the overhead setting of the background wall decorative panel 2. At the same time, by inserting at least one extension member 6 between the fixing member 4 and the adjusting member 5 to increase the overhead width of the background wall decorative panel 2, the increase in the overhead width of the background wall decorative panel 2 is achieved while ensuring that the strength of the connecting structure 3 is not reduced.

[0031] Specifically, the plug strip 602 and the plug slot 601 on the extension piece 6 are both arranged along the length direction of the extension piece 6, and the setting direction of the plug strip 602 is opposite to the opening direction of the plug slot 601, and the plug strip 602 and the plug slot 601 are both located on the center line of the extension piece 6.

[0032] The fixing member 4, the adjusting member 5 and at least one extension member 6 are located on the same straight line. Furthermore, the fixing member 4, the extension member 6 and the adjusting member 5 are connected and arranged in sequence. By arranging the fixing member 4, the adjusting member 5 and the extension member 6 on the same straight line, the connection strength of the entire connection structure 3 is ensured, thereby ensuring the connection and support function for the background wall decorative panel 2.

[0033] The side wall of the plug-in strip 602 is provided with a friction pattern 603 for increasing the connection strength between the extension piece 6 and the fixing piece 4, and the inner wall of the plug-in slot 601 is also provided with a friction pattern 603 for increasing the connection strength between the extension piece 6 and the adjusting piece 5. Furthermore, the friction pattern 603 can be a concave-convex pattern, and the friction pattern 603 is arranged along the length direction of the plug-in strip 602 and the plug-in slot 601.

[0034] A reinforcing rib 604 for improving the structural strength of the extension member 6 is disposed in the plug-in slot 601 . The reinforcing rib 604 is disposed at the bottom of the plug-in slot 601 .

[0035] A connecting groove 401 adapted to the plug-in strip 602 is formed on the fixing member 4 , and the connecting groove 401 is arranged along the length direction of the fixing member 4 .

[0036] Specifically, the fixing member 4 includes a bottom plate connected to the wall 1, a first side plate connected to the bottom plate non-parallel, and a second side plate connected to the bottom plate non-parallel, and at this time, a first insertion groove 511 can be formed between the bottom plate, the first side plate and the second side plate. The bottom plate, the first side plate and the second side plate are integrally formed, and the bottom plate, the first side plate and the second side plate are preferably hollow inside and provided with a support plate structure to reduce material costs while ensuring strength. The bottom plate can be connected to the wall 1 in any way. In the present application, the bottom plate includes a glue connection part and a nail connection part. The glue connection part and the first side plate and the second side plate form the above-mentioned connection groove 401. The glue connection part is provided with a glue groove on the side close to the wall 1 for filling adhesive so that the bottom plate and the wall 1 are glued together, and the nail connection part is connected to the wall 1 by screws. In order to improve the strength of the screw connection, a reinforcement plate is preferably provided in the hollow nail connection part. The reinforcement plate only needs to be non-perpendicular to the wall 1. When the screw is fixed, the screw passes through the front plate of the nail connection part away from the wall 1, the reinforcement plate, and the back plate of the nail connection part close to the wall 1 in sequence and then is inserted into the wall 1.

[0037] A first connecting pattern 402 is formed on the groove wall of the connecting groove 401 and abuts against the friction pattern 603 on the plug-in strip 602. Furthermore, the first connecting pattern 402 is formed on the first side panel and / or the second side panel, and the first connecting pattern 402 is arranged along the length direction of the first side panel and / or the second side panel. When the plug-in strip 602 is plugged into the connecting groove 401, the friction pattern 603 abuts against the first connecting pattern 402, thereby increasing the friction between the plug-in strip 602 and the groove wall of the connecting groove 401, and improving the connection strength between the plug-in strip 602 and the connecting groove 401.

[0038] The adjusting member 5 includes a first adjusting member 501 and a second adjusting member 502 . The second adjusting member 502 is arranged at the end of the background wall decorative panel 2 , and the first adjusting member 501 is arranged at the middle of the background wall decorative panel 2 .

[0039] A first connection strip 5011 matched with the insertion slot 601 is formed on the first adjusting member 501 , and a second connection pattern 5024 abutting against the friction pattern 603 is formed on the side surface of the first connection strip 5011 .

[0040] In cooperation with the connection groove 401, the first adjustment member 501 includes a first connection strip 5011. As long as the first connection strip 5011 can be inserted into the connection groove 401 in a direction not parallel to the wall 1, the distance between the wall panel and the wall 1 can be adjusted. In order to increase the contact area between the first connection strip 5011 and the connection groove 401 and to increase the connection strength between the two, the first connection strip 5011 is preferably a straight plate, and correspondingly, the first side plate and the second side plate of the fixing member 4 are arranged in parallel. At the same time, considering the convenience of adjustment, the present application inserts the first connection strip 5011 into the connection groove 401 in a direction perpendicular to the wall 1, so that the first side plate and the second side plate of the fixing member 4 are both perpendicularly connected to the bottom plate.

[0041] Of course, simply connecting the fixing member 4 and the first adjusting member 501 by plugging has the problem of low connection strength, so after adjusting the depth of the first adjusting member 501 inserted into the fixing member 4, the fixing screw is sequentially passed through the first side plate, the first connecting strip 5011 and the second side plate. At the same time, since several fixing members 4 and first adjusting members 501 are needed during use, the insertion depth of the first adjusting member 501 needs to be adjusted respectively. Usually, the insertion depth of all the first adjusting members 501 is adjusted and then fixed with the fixing screw, so as to avoid repeatedly disassembling and assembling the fixing screw when it is necessary to go back and repeatedly adjust a certain first adjusting member 501. At this time, in order to prevent the first adjusting member 501 from being moved by external force after adjusting the insertion depth, a first connecting pattern 402 is provided on the inner wall of the connecting groove 401, and a second connecting pattern 5024 is provided on the outer wall of the first connecting strip 5011. The first connecting pattern 402 and the second connecting pattern 5024 can be concave and convex patterns. The first connecting pattern 402 and the second connecting pattern 5024 abut against each other, which can increase the friction between the inner wall of the connecting groove 401 and the first connecting strip 5011.

[0042] A second connection strip 5021 matching with the insertion slot 601 is formed on the second adjusting member 502 , and a second connection pattern 5024 abutting against the friction pattern 603 is also formed on the side of the second connection strip 5021 .

[0043] Similarly, the second connecting strip 5021 on the second adjusting member 502 has the same structure as the first connecting strip 5011 on the first adjusting member 501, which will not be elaborated here. The difference is that the second adjusting member 502 also includes an extended edge 5023 abutting against the background wall decorative panel 2, and the end of the extended edge 5023 is provided with a short-circuited edge 5022 arranged parallel to the second connecting strip 5021.

[0044] Specifically, the extended edge 5023 is connected to the second connecting strip 5021, and the extended edge 5023 is parallel to the wall 1. When in use, the depth of the second connecting strip 5021 inserted into the plug slot 601 is adjusted, and after being fixed by screws, the background wall decorative panel 2 is abutted against the extended edge 5023, and it is preferably made flush with the side of the background wall decorative panel 2 away from the wall 1. In addition, since the short-connected edge 5022 is fixedly connected to the end face of the background wall decorative panel 2 by screws, it is not necessary to bear it, but in order to reduce the force on the screws, it is preferably also possible to abut the lower end face of the short-connected edge 5022 against the extended edge 5023.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.

[0046] Although this article uses more of the following terms: wall 1, background wall panel 2, connection structure 3, fixing member 4, connection groove 401, first connection pattern 402, adjusting member 5, first adjusting member 501, first connection strip 5011, second adjusting member 502, second connection strip 5021, short connection edge 5022, extended edge 5023, second connection pattern 5024, extension member 6, plug-in groove 601, plug-in strip 602, friction pattern 603, reinforcing rib 604, etc., it does not exclude the possibility of using other terms.
