Technical Field

[0001] The utility model relates to the technical field of display racks, in particular to a display rack connection structure. Background Art

[0002] The disc-shaped display rack is usually a disc-shaped layer board mounted on a support column, and can rotate freely. Therefore, a support seat for supporting the layer board needs to be installed on the support column.

[0003] In the prior art, the support seat is first sleeved onto the support column in a sleeve-type manner, and then slid to the position provided with threads, and the support seat is screwed to make it cooperate with the threads to achieve installation and fixation on the support column. Since the support seat itself also needs to provide a load-bearing function, the thread accuracy between it and the support column is required to be high to ensure that the display stand as a whole will not shake easily, which has the disadvantages of high product accuracy requirements and complex processing. At the same time, due to the threaded connection, it is inconvenient for users to disassemble and assemble. Utility Model Content

[0023] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0024] refer to Figures 1 to 6 As shown, the utility model discloses a display rack connection structure, including a support column 1, a support sleeve 2 and a layer board 3;

[0025] The side wall of the support sleeve 2 is provided with a fracture 21, so that the radial cross section of the support sleeve 2 is C-shaped, and the peripheral surface of the support sleeve 2 is provided as a first conical surface 22 which is smaller at the top and larger at the bottom;

[0026] A through hole 31 is provided on the layer plate 3, and the inner wall of the through hole 31 is provided as a second conical surface 32 matching the first conical surface 22;

[0027] See also Figure 6 When the product is assembled, the support sleeve 2 is put from the side of the support column 1 to the preset installation position on the support column 1 through the elastically expanded fracture 21 and is fixedly connected to the support column 1. The end of the support column 1 passes through the through hole 31 and makes the second conical surface 32 of the through hole 31 fit with the first conical surface 22. The mutual compression of the second conical surface 32 on the first conical surface 22 makes the support sleeve 2 and the layer board 3 fit tightly, and the three form a set of layer board components; then the support columns 1 of multiple groups of layer board components are connected to obtain a complete display stand.

[0028] Through the above scheme, the utility model can use the fracture 21 of the support sleeve 2 to directly put the support sleeve 2 from the side of the support column 1 to the preset installation position and fix it, without the need to slide the support sleeve 2 for a long distance and twist the support sleeve 2, and the operation is more convenient and quick; after the through hole 31 of the layer plate 3 is aligned with the support column 1 and inserted, it is directly pressed down to the position of the support sleeve 2, and the pressure of the second conical surface 32 on the first conical surface 22 can make the support sleeve 2 and the layer plate 3 fit tightly, completing the assembly of the three, and the reverse operation can be performed for disassembly; the utility model realizes the rapid disassembly and assembly of the layer plate 3 without the aid of tools, and can be assembled by one person, which is convenient, time-saving and labor-saving; the layer plate 3 can rotate freely on the support sleeve 2, so that the user can adjust the direction of the layer plate 3 conveniently.

[0029] Specific embodiments of the present utility model are shown below.

[0030] A circle of limiting ring groove 23 is arranged on the upper end circumference of the above-mentioned first cone surface 22, and a plurality of notches 33 are arranged on the upper end of the through hole 31. Undercuts 34 are arranged in the notches 33. The undercuts 34 are hooked in the limiting ring groove 23 to limit the upward movement of the layer plate 3 relative to the support sleeve 2, thereby playing an upward axial limiting function.

[0031] Furthermore, the upper end circumference of the first conical surface 22 is arranged as a circle of guide bevel surface 24 located above the limiting ring groove 23 , and the guide bevel surface 24 extends to the end surface of the support sleeve 2 , so as to facilitate the compression deformation of the undercut 34 when the layer plate 3 is put into the support sleeve 2 .

[0032] At the same time, the width of the above-mentioned undercut 34 is less than or equal to the width of the break 21. When the layer board 3 needs to be removed, the layer board 1 only needs to be rotated so that one undercut 34 is aligned with the break 21, and the user only needs to break the other undercuts 34 to quickly remove the layer board 3. For example, in this embodiment, there are three undercuts 34, see Figure 4 and Figure 5 In actual operation, the user only needs to break open the two inverted buckles 34, which is more convenient for single-person operation.

[0033] In addition, a circle of limiting convex ring 25 is provided at the bottom of the circumference of the first conical surface 22. The limiting convex ring 25 can receive the layer plate 3 and play a downward axial limiting function.

[0034] The support sleeve 2 can be fixed on the support column 1 by screws or rivets to further improve the stability of the structure. In addition, the support sleeve 2 and the support column 1 can also be fixed by glue.

[0035] Furthermore, a mounting hole 26 is provided on the circumferential surface of the support sleeve 2 (ie, on the first conical surface 22 ) for passing a screw or a rivet.

[0036] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
