Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing technology, and in particular to a screw-on structure for a panel and a crossbeam. Background Technology

[0002] In fields such as architectural decoration, exhibition equipment, and furniture, the connection between panels and beams often needs to meet the requirements of being fast, stable, aesthetically pleasing, and reliable.

[0003] However, the existing method has obvious drawbacks: First, screw fixing requires tools and has low installation efficiency. The screw holes can also damage the appearance and the surface of the panel and crossbeam can be easily damaged during disassembly and assembly. Second, the snap-on connection improves the installation speed, but there is a gap between the snap and the slot. After vibration or long-term use, it is easy to loosen, shake, or even produce abnormal noise, resulting in insufficient stability.

[0004] Therefore, there is an urgent need in this field for a new type of connection structure that can enable quick assembly and disassembly of the panel and the crossbeam, and also provide high rigidity and stability after locking, effectively solving the problems of loosening and abnormal noise. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a rotating connection structure between the panel and the crossbeam, which not only enables quick assembly and disassembly and reduces manufacturing and maintenance costs, but also has the advantages of reliable connection and wide applicability.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A rotary joint structure for a panel and a crossbeam is disclosed. The crossbeam has an upward-opening rotary joint groove. The groove walls on both sides are respectively provided with a first convex arc strip and a first concave arc strip extending along the axial direction of the crossbeam. An elastic rod is inserted into the first concave arc strip. The lower end face of the panel is provided with a rotary joint boss that can be screwed into or out of the rotary joint groove. The screw joint boss has a second concave arc strip and a second convex arc strip on both sides. When the screw joint boss is screwed into the rotary joint groove, the second concave arc strip and the first convex arc strip form a hinge structure through arc surface contact. The second convex arc strip is pressed against the elastic rod, and the lower end face of the panel abuts against the upper surface of the crossbeam to restrict the downward rotation of the panel.

[0008] Furthermore, the cross-sections of the first convex arc strip and the second concave arc strip are both C-shaped, and the radius of the arc surface of the first convex arc strip is equal to the radius of the arc surface of the second concave arc strip.

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

[0010] Furthermore, a transition slope is provided between the upper left surface and the upper right surface, which smoothly connects with the upper left surface and the top of the first convex arc strip respectively; a gap is left between the left side wall of the panel and the transition slope to avoid interference with the left side wall of the panel when the screw-on boss is screwed into the screw-on groove.

[0011] Furthermore, the first convex arc strip and the first concave arc strip are respectively disposed on the left and right sides of the screw joint groove, the screw joint boss is disposed on the lower left side of the panel, and the second concave arc strip and the second convex arc strip are respectively located on the left and right sides of the screw joint boss.

[0012] Furthermore, the rotating boss includes an integrally formed hinge strip and a limiting strip with different heights, the height of the hinge strip being greater than the height of the limiting strip; the hinge strip is located to the left of the limiting strip, the second concave arc strip is formed to the left of the hinge strip, and the second convex arc strip is formed to the right of the limiting strip.

[0013] Furthermore, the first convex arc strip and the first concave arc strip are arranged to pass through the crossbeam along its axial direction; the second convex arc strip and the second concave arc strip pass through the rotating boss of the panel along the crossbeam along its axial direction.

[0014] Furthermore, a baffle portion extends downward from the side end of the panel away from the crossbeam.

[0015] Furthermore, the elastic rod is made of rubber or silicone material.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] First, quick assembly and disassembly: By screwing in and out the screw-in boss and screw-in groove, the panel and crossbeam can be quickly installed and disassembled. The whole process does not require any tools, which greatly improves construction efficiency and is especially suitable for occasions that require frequent assembly and disassembly.

[0018] Secondly, the connection is reliable: after the screw-in boss is screwed into the screw-in groove, the second convex arc strip is pressed against the elastic rod, eliminating the gap between the screw-in boss and the screw-in groove, thus avoiding abnormal noise caused by shaking, loosening and other problems.

[0019] Third, it reduces manufacturing and maintenance costs: By using elastic rods to compensate for tolerances and provide preload, the stringent requirements for machining accuracy of the convex and concave arc strips on the crossbeams and panels are reduced, decreasing machining difficulty and scrap rate. At the same time, the elastic rods have a simple structure, are inexpensive, and are easy to replace even when worn, effectively controlling manufacturing and maintenance costs.

[0020] Fourth, 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 cabinets, tables, and wall decorations.

The rotating boss 31 has a second concave arc strip 312 and a second convex arc strip 311 on both sides. When the rotating boss 31 is screwed into the rotating groove 11, the second concave arc strip 312 and the first convex arc strip 111 form a hinge structure through arc surface contact. The second convex arc strip 311 is pressed against the elastic rod 2, and the lower end face of the panel 3 abuts against the upper surface of the crossbeam 1 to restrict the downward rotation of the panel 3.

[0028] As described above, the cross-sections of the first convex arc strip 111 and the second concave arc strip 312 are both C-shaped, and the radius of the arc surface of the first convex arc strip 111 is equal to the radius of the arc surface of the second concave arc strip 312.

[0029] As described above, the upper surface of the crossbeam 1 includes an upper left surface 12 and an upper right surface 13 with a height lower than the upper left surface 12. The screw groove 11 is provided on the upper right surface 13. The upper surface of the panel 3 is flush with the upper left surface 12, and the lower surface of the panel 3 abuts against the upper right surface 13.

[0030] As described above, a transition slope 14 is provided between the upper left surface 12 and the upper right surface 13. The transition slope 14 smoothly connects with the upper left surface 12 and the top of the first convex arc strip 111 respectively. A gap is left between the left side wall of the panel 3 and the transition slope 14 to avoid interference with the left side wall of the panel 3 when the screw-on boss 31 is screwed into the screw-on groove 11.

[0031] As described above, the first convex arc strip 111 and the first concave arc strip 112 are respectively provided on the left and right sides of the screw-in groove 11, the screw-in boss 31 is provided on the lower left side of the panel 3, and the second concave arc strip 312 and the second convex arc strip 311 are respectively located on the left and right sides of the screw-in boss 31.

[0032] As described above, the rotating boss 31 includes an integrally formed hinge strip 32 and a limiting strip 33 of different heights. The height of the hinge strip 32 is greater than the height of the limiting strip 33. The hinge strip 32 is located to the left of the limiting strip 33. The second concave arc strip 312 is formed to the left of the hinge strip 32, and the second convex arc strip 311 is formed to the right of the limiting strip 33.

[0033] As described above, the first convex arc strip 111 and the first concave arc strip 112 are arranged to pass through the crossbeam 1 along the axial direction; the second convex arc strip 311 and the second concave arc strip 312 pass through the screw-on boss 31 of the panel 3 along the axial direction of the crossbeam 1.

[0034] As described above, a baffle portion 34 extends downward from the side end of the panel 3 away from the crossbeam 1.

[0035] As described above, the elastic rod 2 is made of rubber or silicone material.

[0036] The installation and removal steps for panel 3 are as follows:

[0037] During installation: Align the screw-in boss 31 at the lower end of panel 3 with the screw-in groove 11 of crossbeam 1, so that the opening of the second concave arc strip 312 on the hinge strip 32 faces the first convex arc strip 111 of the screw-in groove 11 and initially abuts against it. Then screw the screw-in boss 31 into the screw-in groove 11. During this process, the second convex arc strip 311 is pressed against the elastic rod 2 until the lower surface of panel 3 abuts against the upper right surface 13 of crossbeam 1, thus completing the installation of panel 3.

[0038] During disassembly: Rotate panel 3 upwards in the direction in which the screw-on boss 31 disengages from the screw-on groove 11 until the second concave arc strip 312 on panel 3 completely disengages from the first convex arc strip 111 on crossbeam 1, thus completing the disassembly of panel 3.
