Description

Technical Field

[0001] This utility model relates to the field of advertising light box technology, specifically to a column-mounted advertising light box that is easy to assemble and connect. Background Technology

[0002] Column-mounted advertising light boxes are widely used in shopping malls, subway stations, outdoor plazas, and other locations to display advertising information. However, in current technology, the assembly of column-mounted light boxes requires multiple sets of screws, making it impossible to directly snap the frame together. This makes it difficult to quickly and accurately position the light box, easily leading to installation deviations and affecting the advertising display effect.

[0003] To address the aforementioned issues, Chinese patent CN222545904U discloses a quick-installation column-wrapping light box. By incorporating a snap-fit ​​component and a fixing component, it solves the problem of low installation efficiency caused by the need for multiple sets of screws during the splicing of column-wrapping light boxes, which prevents the direct snap-fitting of two frames.

[0004] However, this method is not entirely reliable. The engagement of the insert plate and the second mounting plate requires precise alignment, and any deviation can lead to installation inconvenience, especially when visibility is limited or when working at heights. Therefore, a column-mounted advertising light box that is easy to assemble and connect is needed to solve the problem of difficulty in quickly and accurately positioning the light box and the occurrence of installation deviations. Utility Model Content

[0005] This utility model provides a column-mounted advertising light box that is easy to assemble and connect, in order to solve at least one of the above-mentioned technical problems.

[0006] The technical solution adopted by this utility model is as follows: a column-mounted advertising light box that is easy to assemble and connect, including multiple adjacent advertising surfaces, with a first frame, a second frame and an intermediate connector between two adjacent advertising surfaces, the intermediate connector having a first limiting protrusion and a second limiting protrusion respectively cooperating with the first frame and the second frame; the first frame and the second frame having a clamping groove for connecting a canvas on the side near the intermediate connector, the edge of the canvas having an elastic clamping strip that cooperates with the clamping groove.

[0007] Preferably, the advertising surface further includes a back panel, which is connected to the first frame via a snap-fit ​​fastener.

[0008] Preferably, the intermediate connector is connected to the first and second frames via fasteners.

[0009] Preferably, the intermediate connector is provided with at least one guide groove along its length, the cross-section of the guide groove is T-shaped, and the inner walls of the first frame and the second frame are provided with T-shaped protrusions that match the guide groove, the T-shaped protrusions being slidably fitted into the guide groove.

[0010] Preferably, the intermediate connector is provided with anti-loosening teeth between itself and the first frame and the second frame, and the inner walls of the first frame and the second frame are provided with grooves that engage with the anti-loosening teeth.

[0011] Preferably, the anti-loosening teeth have a serrated structure and are evenly distributed along the width direction of the intermediate connector.

[0012] Preferably, the inner wall of the clamping groove is provided with anti-slip texture.

[0013] Preferably, the elastic clip is made of an elastic material, the opening width of the clamping groove is smaller than the thickness of the elastic clip, and the anti-slip texture is a transverse wave shape or a dot matrix protrusion.

[0014] Preferably, the ends of the first limiting protrusion and the second limiting protrusion are square or arc-shaped.

[0015] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows: By setting an intermediate connector with a first limiting protrusion and a second limiting protrusion between adjacent advertising surfaces, and aligning it with the grooves of the first and second frames, a quick snap-fit ​​splicing is achieved, greatly simplifying the splicing process and significantly improving installation efficiency. Simultaneously, this precise fit allows for quick and accurate positioning of the lightbox, effectively avoiding installation deviations and significantly enhancing the advertising display effect. Furthermore, the cooperation between the clamping groove of the intermediate connector and the elastic clips on the canvas firmly fixes the canvas, ensuring the advertising display effect, and overall achieving convenient assembly and connection of the advertising lightbox and stable installation of the canvas. In addition, the elastic pressing design of the clamping groove and the elastic clips allows for convenient canvas replacement without tools.

[0016] In a preferred embodiment of this utility model, the advertising back panel and the first frame are connected by a plug-in buckle. The plug-in buckle connection is simple and convenient to operate. In actual maintenance of advertising light boxes, maintenance personnel only need to press the buckle lightly to connect and disassemble the back panel and the first frame without additional tools. This facilitates later maintenance of the light box, replacement of the canvas or electronic components, etc., thereby improving maintenance efficiency.

[0017] 3. As a preferred embodiment of this utility model, the intermediate connecting piece is connected to the first frame and the second frame by fasteners, which further enhances the connection stability and ensures that the structure of the light box will not loosen or deform due to vibration, external impact or other factors during long-term use, thereby extending the service life of the light box.

[0018] 4. In a preferred embodiment of this utility model, the guide groove of the intermediate connector has a T-shaped cross-section, which slides and engages with the T-shaped protrusions on the inner walls of the first and second frame sides. During the splicing process, the T-shaped protrusions align with the T-shaped cross-section, providing auxiliary positioning and guidance. This facilitates precise positioning of the advertising surface during installation, allowing for easy adjustment of its position to perfectly match the surrounding environment, making the entire installation process efficient and precise. Furthermore, the guide groove limits the range of motion of the T-shaped protrusions within a certain range, enhancing the stability and adjustability of the connection, further improving splicing accuracy and stability, effectively avoiding installation deviations, and ensuring the structural precision of the lightbox.

[0019] 5. As a preferred embodiment of this utility model, anti-loosening teeth and grooves are provided between the intermediate connector and the frame. They mesh with each other to effectively prevent the connection from loosening due to vibration, external impact, etc. during long-term use of the light box, thereby enhancing the connection stability and ensuring the long-term stability and reliability of the light box structure.

[0020] In addition, the anti-loosening teeth are designed in a serrated shape and are evenly distributed along the width of the middle connector, increasing the contact area and friction with the groove. Since the serrated and evenly distributed anti-loosening teeth can provide more uniform and effective anti-loosening resistance, they can better cope with external forces in all directions compared with other shapes or distribution methods. Therefore, they can further improve the anti-loosening effect, ensure the reliability of the connection, and ensure the long-term stable operation of the light box.

[0021] In a preferred embodiment of this invention, the inner wall of the clamping groove is provided with anti-slip texture to increase the friction with the elastic clips at the edge of the canvas, making the canvas installation more secure and ensuring the integrity and stability of the advertising image during lightbox display. The elastic clips are made of elastic material, and the opening width of the clamping groove is smaller than its thickness. During installation, the elastic clips deform elastically and embed into the clamping groove, which, together with the anti-slip texture on the inner wall, greatly improves the firmness of the canvas installation and ensures the advertising display effect.

[0022] As a preferred embodiment of this utility model, the square or arc-shaped structure at the ends of the first and second limiting protrusions facilitates the installation and positioning of the advertising surface. The square structure provides a more stable limiting effect, while the arc-shaped structure can reduce bumps and damage during installation. Choosing the appropriate end structure according to different needs improves the convenience of installation and the reliability of the structure. Attached Figure Description

[0041] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0042] 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. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0045] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "aspect," or "specific example" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0046] Example 1

[0047] like Figure 1-4As shown, a first frame 11, a second frame 12, and a middle connector 13 are provided between two adjacent advertising surfaces 1. The middle connector 13 has a first limiting protrusion 131 and a second limiting protrusion 132 that respectively cooperate with the first frame 11 and the second frame 12. During installation, the first limiting protrusion 131 and the second limiting protrusion 132 on the middle connector 13 are directly aligned with the grooves of the first frame 11 and the second frame 12, achieving quick snap-fit ​​splicing, greatly simplifying the splicing process, and significantly improving installation efficiency. At the same time, this precise fit can quickly and accurately position the lightbox, effectively avoiding installation deviations and significantly improving the advertising display effect. The first frame 11 and the second frame 12 have clamping grooves 17 for connecting the canvas 3 on the side near the middle connector 13, and the edge of the canvas 3 is provided with elastic clips 31 that cooperate with the clamping grooves 17. The elastic clamping strip 31 is made of elastic material. The opening width of the clamping groove 17 is smaller than the thickness of the elastic clamping strip 31. When the canvas 3 needs to be clamped, the elastic clamping strip 31 must first be compressed to cause elastic deformation. With the elastic clamping strip 31 in its deformed state, the canvas 3 is placed into the clamping groove 17. Once the external force is released, the elastic clamping strip 31 will return to its original shape due to its own elastic restoring force. During this process, the elastic clamping strip 31 applies a continuous clamping force to the canvas 3, thereby firmly fixing the material in the clamping groove 17. The inner wall of the clamping groove 17 is provided with anti-slip texture 171, which is a horizontal wave shape or a dot matrix of raised areas, further increasing the friction between the elastic clamping strip 31 and the clamping groove 17, preventing the canvas 3 from moving, enhancing the stability of the canvas 3 connection, and improving the advertising display effect.

[0048] The advertising surface 1 also includes a back panel 2, which is connected to the first frame 11 via a snap-fit ​​buckle 21. The snap-fit ​​buckle 21 connection is simple and convenient to operate; simply press the buckle 21 lightly to firmly clamp the interface, achieving the connection between the back panel 2 and the first frame 11 without additional tools. In actual advertising lightbox maintenance, maintenance personnel can also easily disassemble the back panel from the first frame by simply pressing the buckle 21, facilitating later maintenance, canvas replacement, or electronic component replacement within the lightbox, thereby improving maintenance efficiency. In addition, the intermediate connector 13 is connected to the first frame 11 and the second frame 12 via fasteners 19. This further enhances the connection's stability, ensuring that the structure will not loosen or deform due to vibration, external impact, or other factors during long-term use, thus extending the lightbox's lifespan.

[0049] Specifically, such as Figure 1 , Figure 2As shown, the ends of the first limiting protrusion 131 and the second limiting protrusion 132 are either square or arc-shaped. While facilitating the installation and positioning of the advertising surface, the square structure provides a more stable limiting effect, while the arc-shaped structure can reduce bumps and damage during installation. Choosing the appropriate end structure according to different needs improves the convenience of installation and the reliability of the structure.

[0050] Example 2

[0051] like Figure 5 , Figure 6 As shown, unlike Embodiment 1, the intermediate connector 13 has two guide grooves 134 along its length. The cross-section of the guide grooves 134 is T-shaped. The inner walls of the first frame 11 and the second frame 12 are provided with T-shaped protrusions 1211 that match the guide grooves 134. During the splicing process, the T-shaped protrusions align with the T-shaped cross-section, playing an auxiliary positioning and guiding role. The T-shaped protrusions 1211 are slidably fitted into the guide grooves 134. On the one hand, this facilitates the precise positioning of the advertising surface during installation, allowing for easy adjustment of the advertising surface's position to perfectly match the surrounding environment, making the entire installation process efficient and precise. On the other hand, the guide grooves 134 limit the range of motion of the T-shaped protrusions 1211 within a certain range, enhancing the stability and adjustability of the connection parts, further improving the splicing accuracy and stability, effectively avoiding installation deviations, and ensuring the structural precision of the lightbox.

[0052] Example 3

[0053] like Figure 7 , Figure 8 As shown, a hook 2 for a clothes hanger, differing from embodiment 1, has anti-loosening teeth 133 between the intermediate connecting member 13 and the first frame 11 and the second frame 12. The inner walls of the first frame 11 and the second frame 12 have grooves 114 that engage with the anti-loosening teeth 133. Under the action of these grooves 114, the anti-loosening teeth 133 are restricted to a certain angular range. When a certain external force is generated, the grooves 114 lock the anti-loosening teeth 133 in that position. The mutual engagement effectively prevents the connection from loosening due to vibration, external impact, etc., during long-term use of the lightbox, enhancing the connection stability and ensuring the long-term stability and reliability of the lightbox structure.

[0054] In addition, the anti-loosening teeth 133 are designed in a serrated shape and are evenly distributed along the width direction of the intermediate connector 13, which increases the contact area and friction with the groove 114. Since the serrated and evenly distributed anti-loosening teeth 133 can provide more uniform and effective anti-loosening resistance, compared with other shapes or distribution methods, they can better cope with external forces in all directions, thus further improving the anti-loosening effect, ensuring the reliability of the connection, and ensuring the long-term stable operation of the light box.

[0056] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0057] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
