Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing technology, and in particular to a snap-fit ​​structure between a panel and a crossbeam. Background Technology

[0002] In fields such as architectural decoration and furniture manufacturing, the connection between panels and beams is a crucial link, and its method directly affects assembly efficiency, cost, and applicability.

[0003] Existing connection methods have significant shortcomings: bolt and screw connections are cumbersome, require specialized tools, and are inefficient; snap-fit ​​connections involve disassembling easily damaged parts and suffer from poor reliability after repeated use. Many structures require additional fasteners or complex accessories, demanding high machining precision, increasing costs, and hindering mass production. Furthermore, traditional structures have fixed dimensions, making it difficult to adapt to panels and beams of varying thicknesses, limiting their applicability. Cross-application scenarios require redesign, further increasing costs. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a snap-fit ​​structure for the panel and the crossbeam, which is not only efficient and convenient to assemble and disassemble, but also has the advantages of simple structure, low cost and wide application scenarios.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A hinged structure for a panel and a crossbeam is disclosed. The crossbeam has an upward-opening hinged groove, and the two side walls of the groove are respectively provided with a first convex arc strip and a first concave arc strip extending along the axial direction of the crossbeam. The lower end of the panel is provided with a hinged platform, and the two sides of the hinged platform are respectively provided with a second concave arc strip and a second convex arc strip. The first convex arc strip and the second concave arc strip form a hinged structure through arc surface contact. The first concave arc strip and the second convex arc strip are in arc surface contact for limiting the panel in the transverse direction of the crossbeam. The lower surface of the panel abuts against the upper surface of the crossbeam to restrict the panel from rotating downward.

[0007] Furthermore, the swivel table has an integrally formed hinge strip and a limiting strip, the second concave arc strip is located on the side of the hinge strip facing the crossbeam, and the second convex arc strip is located on the side of the limiting strip facing away from the crossbeam.

[0008] Furthermore, the cross-sections of the first convex arc strip and the second concave arc strip are both C-shaped, and the height of the hinge strip is greater than the height of the limiting strip. When the panel is installed in place, the side wall of the hinge strip below the opening of the second concave arc strip is adjacent to the groove wall of the swivel groove below the first convex arc strip.

[0009] Furthermore, the upper surface of the crossbeam includes an upper left surface and an upper right surface that is lower in height than the upper left surface. The upper surface of the panel is flush with the upper left surface, the swivel groove is located on the upper right surface, and the lower surface of the panel abuts against the upper right surface.

[0010] Furthermore, the first convex arc strip and the first concave arc strip are located on the left and right groove walls of the swivel groove, respectively. The left side of the panel faces the crossbeam. The swivel platform is located at the lower left end of the panel. The second concave arc strip and the second convex arc strip are located on the left side of the hinge strip and the right side of the limiting strip, respectively.

[0011] Furthermore, a transition slope is provided between the upper left surface and the upper right surface. The transition slope smoothly connects with the top of the upper left surface and the top of the first convex arc strip, respectively. A gap is provided between the left side wall of the panel and the transition slope to prevent interference between the left side wall of the panel and the transition slope when the screw fastener is rotated into the screw fastener groove.

[0012] Furthermore, the radius of the first convex arc strip is equal to the radius of the second concave arc strip, and the radius of the first concave arc strip is equal to the radius of the second convex arc strip; the first convex arc strip and the first concave arc strip are both arranged to penetrate through the crossbeam axially, and the second convex arc strip and the second concave arc strip are both arranged to penetrate through the panel along the crossbeam axially.

[0013] Furthermore, the panel has a downwardly extending baffle at the side end facing away from the crossbeam.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] First, assembly and disassembly are highly efficient and convenient: Through the arc-shaped hinge structure of the first convex arc strip and the second concave arc strip, the panel can rotate around the hinge axis to achieve screwing in and screwing out, without relying on fasteners such as bolts and screws. During assembly, only rotating the panel is required to complete the fixation, and during disassembly, rotating in the opposite direction is sufficient to separate the panels, which greatly improves the installation efficiency and is especially suitable for mass production or rapid on-site construction scenarios.

[0016] Secondly, the structure is simple and the cost is low: the screw groove, screw platform and convex and concave arc strips can all be integrally formed by mold. For example, the crossbeam is formed by extrusion molding and the panel is formed by injection molding or stamping. No additional fasteners or complex accessories are required, which reduces processing and material costs and is suitable for large-scale industrial production.

[0017] Third, it has a wide range of applications: by adjusting the size and position of the convex and concave arc strips, it can be adapted to panels and beams of different thicknesses, and is suitable for various scenarios such as ceilings, cabinets, tables, and wall decorations.

A gap is provided between the left side wall of the panel 2 and the transition slope 14 to prevent interference between the left side wall of the panel 2 and the transition slope 14 when the screw fastening table 21 rotates and screws into the screw fastening groove 11.
