Description

Technical Field

[0001] The invention belongs to the technical field of advertising equipment, and in particular relates to an advertising display stand. Background Art

[0002] Advertising display stands are a commonly used type of advertising equipment for advertising and product display. Previous advertising display stands have been structurally imperfect, with drawbacks such as complex structure, difficulty in production, poor stability, easily damaged accessories, excessive material consumption, and high production costs. CN215495933u discloses a display stand, which is a representative example of previous display stands. Its structure reveals that the profiles used for its main components, such as the top frame, bottom frame, left frame, right frame, and rear support, are all single-cavity profiles. This type of profile is structurally unstable, has poor torsional resistance, and is prone to deformation and damage. Furthermore, the assembly of the display board requires additional fixings on the main frame, resulting in a complex structure and cumbersome, labor-intensive, and time-consuming production. Furthermore, the connection between the main frame and the rear support frame requires multiple holes in the frame, significantly reducing strength and increasing production difficulty. Some display stands use beveled butt joints for their frames, which require a 45-degree bevel to be machined first. However, this can only be done piece by piece, making the processing and assembly more time-consuming and labor-intensive. After assembly, the frames are less compact and tighter, and are prone to defects such as butt joint gaps and uneven surfaces. Furthermore, most previous display stands can only display one specification of sign, resulting in a limited range of applications. To address the problems and shortcomings of previous advertising display stands, we have independently developed an advertising display stand that uses a new double-cavity profile. All major components use the same profile, and all major components are flat-jointed. This not only reduces the difficulty of manufacturing and processing, but also effectively avoids waste of raw materials, reducing production costs by over 30%, which can greatly improve the company's production efficiency. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an advertising display stand which has a compact structure, is easy to assemble, has strong stability, saves raw materials, has low cost, and can be assembled with billboards of various specifications.

The outer shapes of the external connector and the internal connector are similar to the first assembly cavity and the second assembly cavity, respectively.

[0009] Moreover, the built-in connectors are divided into Type A built-in connectors and Type B built-in connectors. The Type A built-in connectors and Type B built-in connectors are respectively arranged between the upper frame of the display board and the left side frame and the right side frame, and between the lower frame of the display board and the right side frame and the left side frame. The structures of Type A built-in connectors and Type B built-in connectors are mirror images, and are both composed of an inner connecting block with a first nut assembly groove and a screw hole formed thereon, and an outer connecting block with a second nut assembly groove and a screw hole formed thereon. The inner connecting block is integrally formed inside and the outer connecting block is integrally formed outside. The joint of the inner connecting block and the outer connecting block symmetrically forms a U-shaped limiting groove with an arc-shaped ridge formed therein. The outer shapes of the inner connecting block and the outer connecting block are similar to the inner shapes of the first assembly cavity and the second assembly cavity, respectively.

[0010] Moreover, the corner connector is composed of a horizontal tube body, a vertical tube body and reinforcing ribs, all of which are provided with assembly tube cavities. The horizontal tube body and the vertical tube body are vertically intersected and integrated into one body.

DETAILED DESCRIPTION

[0048] The present invention will be further described in detail below through specific examples. The following examples are only illustrative and not restrictive, and the scope of protection of the present invention cannot be limited thereto.

[0049] An advertising display stand includes a display stand body 1, a support frame 3, a display board, a hinged connecting plate 2, and a split hinged connector. The hinged connecting plate and the split hinged connector are both connected between the display stand body and the support frame. The display stand body and the support frame are hingedly connected in a herringbone pattern. The display board is disposed in the upper middle portion of the display stand body. The display board has a certain degree of elasticity.

[0050] The display stand body is composed of a top frame 7, a bottom frame 4, a left frame 5, a right frame 9, an upper display frame 8, a lower display frame 10, corner connectors 6, and built-in connectors. The top frame, bottom frame, left frame, and right frame are located in the upper, lower, left, and right corners, respectively. The corner connectors are located at the four corners and connected to form a rectangular frame. The upper display frame is horizontally arranged in the upper part of the rectangular frame, and the lower display frame is horizontally arranged in the lower part of the rectangular frame. The built-in connectors are connected between the upper display frame, the lower display frame, the left frame, and the right frame (the left and right here refer to the left and right positions of the human body when facing the front of the display stand, and the left and right mentioned later without separate explanation are the same).

[0051] The support frame is composed of a bottom beam 47, a left support rod 49, a right support rod 45, and corner connectors 46 and 50. The bottom beam is located in the center of the bottom, the left support rod and the right support rod are located on the left and right sides, and the corner connectors are located between the bottom beam and the left support rod and the right support rod to connect them as a whole.

[0052] Its innovation lies in the following: the top frame, bottom frame, left frame, right frame, upper and lower frames of the display board, bottom beam, left and right support rods are all cut and made from a completely new double-cavity profile. This new double-cavity profile consists of a base plate 11, sidewalls, a spacer 14, and an L-shaped stopper 17. The base plate is centered, the sidewalls and L-shaped stoppers are connected in sequence and symmetrically on either side, and the spacer and base plate are parallel and located in the middle of the sidewalls, forming a single double-cavity tubular component. The outer side of the spacer forms a first assembly cavity 12, and the inner side forms a second assembly cavity 15. The sidewalls have an outer wall section 13 outside the spacer and an inner wall section 16 inside the spacer. The spacer is formed in the middle of the profile to act as a reinforcement rib, stabilizing the profile structure, enhancing torsional resistance, and preventing deformation and damage. The spacer is longer than the base plate. In this embodiment, the reinforcement rib is 11 mm long, while the base plate is 9.58 mm long. The first assembly cavity is assembled correspondingly with the external connector of the lower hinged body and the internal connection block of the built-in connector; the second assembly cavity is used for assembling correspondingly with the external connection block of the built-in connector; the second assembly cavity can also be used to assemble a display board, which can be directly embedded in the second assembly cavity without the need to set up additional display board assembly components, thereby reducing the complexity of the product structure.

[0053] When assembling the upper and lower frames of the display board, the inner connecting blocks of the built-in connecting parts are inserted into the first assembly cavities of the upper and lower frames of the display board, and the outer connecting blocks of the built-in connecting parts are inserted into the second assembly cavities of the left and right frames. At this time, the L-shaped limiting parts are just embedded in the U-shaped limiting groove between the inner and outer connecting blocks of the built-in connecting parts, limiting the outward expansion of the left and right frames, effectively ensuring that the display stand is connected tightly, seamlessly, stably and firmly.

[0054] The split hinged connector is divided into a left split hinged connector and a right split hinged connector. The left and right split hinged connectors are mirror images of each other, each consisting of an upper hinged body 51 and lower hinged bodies 44 and 48. The upper hinged body is fixed to the upper back of the left and right frames of the display stand, respectively, and the lower hinged body is fixed to the top of the left and right support rods, respectively. The upper and lower hinged bodies can be hingedly connected or disassembled as needed. They are hingedly connected when displayed and can be disassembled for easy packaging and storage when stored.

[0055] The upper hinge body consists of a hinge plate 19 with a central screw hole 20, a stop bar 18 on the outer end, a thickened portion 24 on the inner surface of the outer end, a hinge connecting block 22 with a hinge axis 23, and a reinforcing rib 21. The hinge plate and hinge connecting block are integrally connected, with the reinforcing rib located between them. The thickened portion ensures a tight, smooth, and gap-free connection between the hinge plate and the display frame. The stop bar prevents twisting and deformation of the hinge plate, ensuring a secure connection.

[0056] The lower hinged body is composed of a hinge seat 25, an external connector 26, and an internal connector 28. The hinge seat is on the top, the external connector is on the lower outside, and the internal connector is on the lower inside, which are made into one piece. An assembly groove 27 corresponding to the partition plate is formed between the external connector and the internal connector. The external connector and the internal connector have shapes similar to the first assembly cavity and the second assembly cavity, respectively. The inner edge of the hinge seat is flush with the outer and inner connectors, and the outer and front edges of the hinge seat bottom surface are larger than the outer and inner connector top surfaces. The width of the larger edge is the wall thickness of the profile, and the rear edge is larger than the front edge by a certain width. A step surrounded on three sides is formed between the hinge seat and the external and inner connectors. When the external and inner connectors are inserted into the first and second assembly cavities of the left and right support rods, the front, inner, and outer surfaces are exactly flush, and the rear side protrudes slightly by a certain width. The rear side protrudes slightly by a certain width, so that the axis hole on the hinge seat can be moved back appropriately, and the hinge is not easy to slip after the hinge is connected to the hinge seat (the front and back here are opposite to the front and back of the display stand).

[0057] Built-in connectors are categorized as Type A and Type B. Type A and Type B connectors are located between the upper frame and the left and right sides of the display, respectively, and between the lower frame and the right and left sides of the display. Both Type A and Type B connectors are structurally identical, consisting of an inner connecting block 29 with a first nut mounting groove 30 and a screw hole 35, and an outer connecting block 32 with a second nut mounting groove 34 and a screw hole 36. The inner connecting block is integrally formed on the inside, while the outer connecting block is formed on the outside. The symmetrical junction of the inner and outer connecting blocks forms a U-shaped retaining groove 31 with an arcuate ridge 33. The outer and inner connecting blocks have similar shapes to the inner and second mounting cavities, respectively. (Here, "inside" and "outside" refer to the longitudinal or transverse centerline of the display stand, with "inside" being closer to the center and "outside" being farther from the center.) The U-shaped retaining groove has three curved ridges on its inner bottom surface, located in the middle and at both ends. These ridges allow the outer connecting block (the male connecting block) of the built-in connector to fit smoothly into the second assembly cavity of the left and right frames during assembly. The first and second nut assembly slots are used to pre-install nuts.

[0058] The corner connector consists of a transverse tube 38, a vertical tube 40, and reinforcing ribs 39, all with mounting lumens 37. The transverse and vertical tubes intersect at right angles, forming a single unit. Ribs are located between the transverse and vertical tubes, and the intersection of the two tubes is rounded. The internal shape of the mounting lumen is similar to that of the new dual-lumen profile. This similarity allows for direct insertion and connection between the left and right side frames and the corner connector.

[0059] The upper and lower display frames share the same structure, with oblong positioning adjustment holes 41 formed at both ends of their backs. These holes allow for fine-tuning of the gaps between the left and right sides and the ends of the upper and lower display frames, eliminating assembly gaps and ensuring a seamless, tight structure and a smooth, aesthetically pleasing appearance. The built-in connectors at both ends of the upper and lower display frames can be rotated 180 degrees and interchanged with each other.

[0060] The left and right frames are mirror images of each other, with one to three lower positioning screw holes 43 formed on the lower portion of the upper back surface, and one to three upper positioning screw holes 42 formed on the upper portion of the upper back surface. The upper positioning screw holes are oblong in shape. In this embodiment, there are three lower and upper positioning screw holes, and the spacing between the screw holes can be five centimeters or ten centimeters as needed. The three upper and lower positioning screw holes can be used to assemble display boards of various specifications. The upper and lower positioning screw holes can also be used to adjust different heights to meet the visual needs of different audiences to ensure that the display has the best visual effect; the upper positioning screw holes are oblong in shape, which can adjust the gap between the upper frame of the display board and the display board to ensure that the display board is installed tightly, seamlessly, firmly and stably.

[0061] The bottom plate, first side wall plate, second side wall plate, and partition plate are all rounded at their connection points. The outer rounded corners can make the product appearance smooth and beautiful, while the inner rounded corners can increase the strength.

[0062] assembly:

[0063] 1. Before assembly, prefabricate nuts in the first and second nut assembly grooves of the built-in connector.

[0064] 2. Assemble the upper and lower display frames: Insert the left and right ends of the upper display frame into the Type A built-in connector and the Type B built-in connector respectively, and use screws through the oblong positioning adjustment holes, screw holes, and prefabricated nuts to connect and secure the built-in connector to the upper display frame. Insert the left and right ends of the lower display frame into the Type B built-in connector and the Type A built-in connector respectively, and similarly use screws through the oblong positioning adjustment holes, screw holes, and prefabricated nuts to connect and secure the built-in connector to the upper display frame.

[0065] 3. Assemble the display board frame: Install the Type A built-in connectors and the external connection blocks of the Type B built-in connectors at both ends of the assembled upper and lower display board frames into the second assembly cavities of the left and right frames respectively from the upper and lower ends of the left and right frames. Use screws to fix the lower display board frame to the corresponding lower positioning screw holes according to the required height.

[0066] 4. Assemble the top and bottom frames: Attach the corner connectors to the top and bottom frames, respectively. Then, connect the corner connectors to the left and right frames. Because the inner shape of the corner connectors' assembly cavities is similar to the outer shapes of the left and right frames, assembly is straightforward and very convenient.

[0067] 5. Assemble the support frame: install the upper hinges of the left split hinge and the right split hinge at the designed positions on the back of the left side frame and the right side frame respectively and fix them with screws; connect the bottom beam, left support rod and right support rod of the support frame through the corner connectors, and insert the lower hinges of the left split hinge and the right split hinge into the top of the left support rod and the right support rod respectively; connect and fix the two ends of the hinged connecting plate to the designed positions of the left side frame, right side frame and the left support rod and the right support rod respectively.

[0068] 6. Assemble the display board: Slightly lift the upper frame of the display board, slightly bend the display board, and install it into the second assembly cavity of the left and right frames. Push the display board downward and insert it into the second assembly cavity of the lower frame of the display board. Push the upper frame downward and clamp the display board with the second assembly cavity of the upper frame of the display board. Secure the upper frame with screws.

[0069] 7. Fine-tune the gaps between the left and right frames and the upper and lower frames of the display board: After completing the above assembly, if the gaps between the left and right frames and the upper and lower frames of the display board are too large, press the left and right frames inward with appropriate force, adjust the position of the screws in the oblong positioning adjustment holes, and then tighten the screws.

[0070] 8. Set up the display: After the display board is assembled, put the hinge seat and hinge together, stretch the display stand body and support frame from the bottom outward until the hinged connecting plate is straight, and the installation is complete.

[0071] Since the top frame, bottom frame, left frame, right frame, bottom beam, left support rod and right support rod of this advertising display stand are all made by cutting a new type of double-cavity profile, all the main components of one profile are easy to make, there is no scrap when cutting, saving raw materials and low production cost, and because all are flat-end connections, the whole bundle can be sawed when cutting, which greatly improves the cutting efficiency. The present invention is provided with a built-in connector, which makes the connection more convenient and more secure. The new double-cavity profile of the present invention has a trapezoidal shape and is provided with a partition plate therein. It has a beautiful appearance, a solid structure, is not easy to deform, and is not easy to damage. The new double-cavity profile of the present invention is provided with a first assembly cavity and a second assembly cavity, which are convenient for assembly and connection. The hinged plate of the present invention is provided with a limit strip, which can limit the rotation of the hinged plate after assembly and ensure a stable connection. The present invention is provided with an oblong positioning adjustment hole, which can avoid the occurrence of assembly gaps and has a smooth, round and beautiful appearance; it is provided with three lower positioning holes and three upper positioning holes, which can be used to assemble billboards of various specifications, and can also be adjusted to different heights to meet the visual needs of different audiences, so as to ensure that the display has the best visual effect.
