Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] The purpose of this utility model is to provide a board fastener and an art board to solve the problems existing in the prior art, reduce transportation costs, and facilitate on-site production of art boards.
[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.
[0031] This utility model provides a plate fixing component, including: a profile 1 and a corner connector 2. The inner side of the profile 1 is constructed with a limiting groove 11 extending along its own length direction. The inner side refers to the side of the profile 1 facing the plate when assembling the art board. The limiting groove 11 is used for inserting the edge of the plate. Both ends of the profile 1 are constructed with connecting holes 17. At least two connecting parts are constructed on a corner connector 2, and one connecting part corresponds to one connecting hole 17. The connecting part can be inserted and locked in the connecting hole 17.
[0032] The panel fastener provided by this utility model is used to edge the panels used to construct art panels. It abandons the traditional method of welding the panels to the profile 1, and the method of edge-wrapping the panels using the panel fastener is more convenient. It eliminates the need for factory prefabrication and allows for on-site assembly. This also enables separate packaging of the panels, profile 1, and corner connector 2 during transportation, facilitating transport and allowing for the on-site cutting of panels and profile 1 to any size, enabling rapid production of art panels of any size on-site. Furthermore, since welding is not required, the defect of uneven stress caused by welding leading to localized deformation of the art panel is eliminated.
[0033] In some embodiments, the connecting part includes two strips 21, which are spaced apart and can be inserted into the connecting hole 17. In the inserted state, the opposite sides of the two strips 21 are pressed against the inner wall of the connecting hole 17 to achieve the connection part being locked in the connecting hole 17.
[0034] Specifically, the opposite sides of the two strips 21 are the outer surfaces. The two opposing inner walls of the connecting hole 17 are used to contact the outer surfaces of the strips 21. When the strips 21 are not inserted into the connecting hole 17, the ends 22 of the two strips 21 are flush. The distance between the ends 22 of the outer surfaces of the two strips 21 is smaller than the lateral dimension of the connecting hole 17. This is to facilitate the insertion of the strips 21 into the connecting hole 17. The maximum distance between the outer surfaces of the two strips 21 is greater than the lateral dimension of the connecting hole 17. This is to facilitate the pressing of the strips 21 against the inner wall of the connecting hole 17 after insertion. The maximum distance 24 between the outer surfaces of the two strips 21 and the ends 22 of the outer surfaces of the strips 21 are smoothly transitioned. This is to facilitate the insertion of the strips 21 into place.
[0035] This embodiment provides a specific method for locking and fixing the connecting part and the connecting hole 17 after they are inserted. It can be understood that the locking in this embodiment is similar to the interference fit connection method.
[0036] It should be noted that the profile 1 and the corner connector 2 are usually made of metal. Therefore, the two strips 21 in the corner connector 2 usually have a certain degree of elasticity, which is conducive to the elastic deformation of the two strips 21 and their insertion into the connecting hole 17, as well as the pressing of the strips 21 against the inner wall of the connecting hole 17 after insertion.
[0037] In some embodiments, a stepped structure 25 is constructed at the maximum distance 24 between the outer surfaces of the two slats 21, with the upper stepped surface 26 extending to the end 22 of the slat 21 and the lower stepped surface 27 extending to the initial end 23 of the slat 21.
[0038] The stepped structure 25 in this embodiment can be regarded as a "barb". Unlike a "barb", which is usually needle-shaped, the stepped structure 25 of this application has a prismatic structure, which is used to prevent the strip 21 from moving out of the connecting hole 17.
[0039] In some embodiments, the present invention includes four profiles 1 and four corner connectors 2. The four profiles 1 are respectively used to be disposed on the four sides of the plate, and the ends of the four profiles 1 are connected end to end by the four corner connectors 2 to form a closed ring structure.
[0040] The sheet metal fastener provided in this embodiment is suitable for edge wrapping of rectangular sheet metal.
[0041] Of course, other examples may include five profiles 1 and five corner connectors 2, which is suitable for edge wrapping a pentagonal structure of sheet metal.
[0042] In some embodiments, the profile 1 has a through hole extending through the length direction, and the through hole forms two side holes 16 and a central hole 15 along the width direction. The ends of the two side holes 16 form connecting holes 17. The inner surface of the profile 1 has a groove 13 extending through the profile 1 along the length direction. The groove 13 and the central hole 15 are connected, and the limiting groove 11 and the central hole 15 form a limiting groove 11.
[0043] This embodiment defines a specific construction form for the connecting hole 17 and the limiting groove 11.
[0044] In some embodiments, a partition 14 extending along the length of the profile 1 is provided between the central hole 15 and the side hole 16.
[0045] In this embodiment, the partition 14 has a limiting function to improve the connection stability between the strip 21 and the plate.
[0046] In some embodiments, two limiting plates 12 extending into the through hole are fixedly connected to the two edges of the slot 13. Both limiting plates 12 extend along the length direction of the through hole, and the two limiting plates 12 and the two partitions 14 are respectively disposed on the same plane.
[0047] In some embodiments, the two slats 21 gradually move away from each other along the direction from the initial end 23 to the end 22.
[0048] This embodiment is beneficial to further improve the clamping force between the strip 21 and the inner wall of the connecting hole 17.
[0049] In some embodiments, such as Figure 5 As shown, the corner connector 2 includes not only the strip 21, but also a connector body 28 for integrating all the strips. The inner side of the connector body 28 is provided with a slot 29 for inserting the corner of the board and for limiting the insertion of the board.
[0050] Understandably, the ultimate purpose of setting the slot on the connector body 28 is actually to improve aesthetics, such as... Figure 2 As shown, after the slot is set, the edge of the plate is inserted into the limiting groove on the inside of the profile, and the corner is inserted into the slot on the inside of the connector body 28. This helps to achieve seamless connection between the profile and the corner connector 2, or to minimize the gap between the two, thereby improving the aesthetics.
[0051] The dimensions of the connector body 28 need to be compatible with the cross-sectional dimensions of the profile, so that the outer surface of the connector body 28 and the outer surface of the profile are on the same plane.
[0052] Example 2
[0053] This utility model provides an art board, including a board and the board fixing component described in Embodiment 1. In the assembled state, the edge of the board is inserted into the limiting groove 11 inside the profile 1, and any two adjacent profiles 1 are connected and fixed by a corner connector 2.
[0054] This embodiment possesses all the advantages of Embodiment 1, and will not be repeated here.
[0055] In some embodiments, the sheet material is typically an aluminum sheet, and the aluminum sheet and sheet fasteners constitute an artistic aluminum sheet.
[0056] During on-site assembly, cut the boards and profiles to the appropriate length and width as needed, then insert the edges of the boards into the limiting grooves of the profiles, and use corner connectors to connect any two profiles until all the profiles are connected into a closed ring structure. This completes the assembly process of the art board.
[0057] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
