[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0018] Reference Figures 1-4 This embodiment of the present invention provides a multi-directional quick connection device for advertising display stands, comprising: The support mechanism 100 includes a display panel 110, an adjustment component 120 disposed on the outside of the display panel 110, and a support component 130 disposed at the bottom of the adjustment component 120; The connecting mechanism 200 includes a housing 210 movably sleeved at the connection between the adjusting component 120 and the supporting component 130, a bearing 220 fixedly installed on the outside of the housing 210, and a lever 230 hinged to the inner cavity of the bearing 220.

[0019] The modular connection between the display panel 110 and the support structure is achieved through the coordinated arrangement of the bearing mechanism 100 and the connecting mechanism 200. The linkage design between the adjustment component 120 and the support component 130 makes the overall structure highly adaptable. The movable sleeve structure of the housing 210 allows the device to be flexibly adjusted under different working conditions. The hinged design of the bearing seat 220 and the lever 230 provides a convenient operating interface, which significantly improves the convenience of the display stand assembly and the reliability of the connection.

[0020] Specifically, the connecting mechanism 200 also includes a positioning insertion hole 240 opened on the outside of the bearing seat 220, an expansion tube head 250 fixedly installed on the outside of the housing 210, and an anti-slip ring 260 fixedly installed on the inner wall of the housing 210.

[0021] The positioning socket 240 forms a standardized expansion interface, which facilitates the implementation of additional functions. The expansion tube head 250 enhances the compatibility of the connection mechanism 200, making it adaptable to various specifications of display rack components. The anti-slip ring 260 is fixedly installed on the inner wall, which effectively increases the frictional resistance of the connection part and prevents unexpected sliding during use.

[0022] Furthermore, the adjustment assembly 120 includes a bracket 121, a damping bushing 122 hinged to the top of the bracket 121, and a hole seat 123 fixedly installed on the outside of the bracket 121 and movably engaged with the display panel 110. The back of the display panel 110 is provided with a protrusion connected to the hole seat 123. The adjustment assembly 120 also includes a rotating shaft 124 hinged to the bottom of the bracket 121, and a plug rod 125 fixedly installed at the bottom of the rotating shaft 124. The end of the plug rod 125 is movably inserted into the upper half of the cavity of the housing 210 to form an axial sliding fit.

[0023] Among them, the bracket 121, as the basic load-bearing component, ensures the overall rigidity of the structure. The hinged design of the damping bushing 122 enables the display panel 110 to have a fine-tuning function. The snap-fit ​​between the hole seat 123 and the protrusion on the back of the display panel 110 enables quick positioning and installation. While ensuring connection strength, it provides flexible angle adjustment capability. The hinged structure of the rotating shaft 124 enables the bracket 121 to have multi-directional rotational freedom. The axial sliding fit between the insertion rod 125 and the inner cavity of the housing 210 forms a stable guiding mechanism, which not only ensures connection accuracy but also allows for appropriate displacement compensation.

[0024] Preferably, the support assembly 130 includes a support leg 131, a support head 132 fixedly mounted on the top of the support leg 131, a locking block 133 fixedly mounted on the top of the support head 132, and a locking groove 134 opened on the outside of the locking block 133. The locking block 133 is elastically deformable and engages with the lower half of the inner cavity of the housing 210 to form a radial constraint mechanism. The support assembly 130 also includes a support crossbar 135 fixedly mounted on the inside of the support leg 131, and a support rope 136 fixedly mounted on the outside of the support crossbar 135.

[0025] Among them, the support leg 131 and the support head 132 form a stable basic support structure. The elastic snap-fit ​​design of the locking block 133 enables quick locking with the housing 210. The setting of the slot 134 and the cooperation of the radial constraint mechanism ensure the anti-torsion performance of the connection part. While ensuring quick assembly and disassembly, it provides reliable mechanical support. The support crossbar 135 enhances the structural linkage between the support legs 131. The setting of the support rope 136 provides additional tension support and effectively disperses the load stress.

[0026] Furthermore, the protrusion of the paddle 230 and the slot 134 form a detachable snap-fit ​​engagement to achieve a mechanical interlock function. The inner cavity of the positioning socket 240 is configured as a standard insertion station, which is suitable for the axial insertion of the external support wire, thereby forming a bidirectional limiting effect on the paddle 230 to prevent its unexpected displacement.

[0027] The detachable engagement of the lever 230 and the slot 134 forms a clear mechanical interlock indication, while the standard insertion design of the positioning socket 240 standardizes the limit operation. The bidirectional limit mechanism effectively prevents the lever 230 from accidentally disengaging. This structural design simplifies the operation process while ensuring the reliability of the connection.

[0028] In use, firstly, the protrusion on the back of the display panel 110 is quickly engaged with the hole seat 123 of the adjustment component 120 to complete the initial installation of the display unit. Then, the insertion rod 125 is inserted axially into the upper part of the inner cavity of the housing 210 to form a sliding fit. At the same time, the elastic locking block 133 of the support component 130 automatically engages with the lower part of the inner cavity of the housing 210 to form a radial constraint. After the protrusion of the lever 230 and the slot 134 complete the mechanical interlock, the support steel wire is inserted through the positioning insertion hole 240 to achieve bidirectional limiting and fixing. Finally, other display rack components are connected through the expansion tube head 250 to form a complete display system.

[0029] In summary, the coordinated operation of the supporting mechanism 100 and the connecting mechanism 200 constructs a modular display stand connection system. The linkage design of the display panel 110 and the adjustment component 120 not only ensures the flexible adjustment of the display angle, but also achieves stable axial positioning through the precise sliding fit between the insertion rod 125 and the housing 210. The support component 130 adopts a unique design that combines an elastic snap-fit ​​mechanism with radial constraints, so that the snap-fit ​​block 133 and the housing 210 form a reliable and quick locking mechanism. Together with the three-dimensional support network formed by the support crossbar 135 and the support rope 136, the deformation resistance of the overall structure is significantly improved. The innovative design of the connecting mechanism 200's paddle 230 mechanical interlocking system, in conjunction with the standardized positioning socket 240, enables quick assembly and disassembly while effectively preventing accidental disengagement through a two-way limiting mechanism.
