Abstract
Description
Technical Field
[0001] This utility model belongs to the field of light box technology, specifically relating to a collision-resistant corner connection structure for light boxes. Background Technology
[0002] In today's market environment where light boxes are widely used, whether it is an outdoor light box used for advertising on a busy street or an indoor light box used for product display in a shopping mall or store, the corner parts of the light box are often connected by connecting components to ensure the structural stability and strength of the light box.
[0003] Existing technologies, such as the utility model with publication number CN211264872U, disclose a corner connector for a lightbox. This patent uses a corner base, an extension portion, two first connecting portions, and two second connecting portions. The two first connecting portions and two second connecting portions are located at both ends of the corner base, and the included angle between the two first connecting portions and the two second connecting portions is 90°. The included angle between the extension direction of the extension portion and the extension directions of the two first connecting portions and the two second connecting portions is 135°. A T-shaped groove is provided in the middle of the extension portion, and the two sides of the extension portion form a clamping groove with the base. However, due to its sharp corners, during installation and daily use, especially in places with dense crowds, there may be collisions between people and the lightbox, posing a significant threat to personal safety.
[0004] Furthermore, in places like markets and train stations where people and goods travel side by side, when the corner of the lightbox is hit by goods or luggage, the outer shell of the lightbox is very likely to crack or deform. This not only seriously affects the safety of the lightbox, but may also damage key components such as internal lighting elements and circuits, thus causing the lightbox to malfunction and significantly increasing maintenance and time costs.

[0044] Example 1
[0045] A preferred embodiment, such as Figure 1 As shown, a collision-resistant corner connection structure for a lightbox includes a lightbox frame 1 and a corner body 2. The lightbox frame 1 has multiple positioning grooves 11 for mating with connecting posts 221 of the corner body 2. The corner body 2 includes a protective part 21 and a connecting part 22. The protective part 21 is provided on the outside of the corner body 2. The protective part 21 has a buffer layer 212 and a protective shell 211. The buffer layer 212 is used to absorb external impact forces, and the protective shell 211 is used to protect the corner body 2. The buffer layer 212 is made of elastic material and can absorb and disperse collision impact forces, effectively reducing collision damage. The protective shell 211 can prevent the lightbox frame 1 from directly bearing external collision forces, avoiding deformation and damage to the lightbox frame 1 due to direct force. Figure 2 As shown, the buffer layer 212 is detachably connected to the protective housing 211. When the buffer layer 212 is damaged due to long-term use or accidental damage, it can be easily replaced, reducing maintenance costs.
[0046] like Figure 3As shown, the connecting part 22 has a slot 222 that connects to the canvas fixing member 14 and a connecting post 221 that connects to the positioning groove 11 of the lightbox frame 1. The connecting post 221 is used to connect with the positioning groove 11 of the lightbox frame 1 to achieve quick installation of the corner body 2 and the lightbox frame 1. The canvas fixing member 14 can be a support post, hook, or snap-on structure, etc. The corner body 2, by setting the slot 222 that connects to the canvas fixing member 14, can meet different canvas installation requirements and expand the applicability of the lightbox corner. The corner body 2, through the connection post 221 and the side fastener 2211, connects with the positioning groove 11 of the lightbox frame 1 to ensure a stable connection between the lightbox frame 1 and the corner body 2, ensuring the stability of the overall structure of the lightbox. The lightbox frame 1 is also provided with a canvas groove 12 and a pressure cover 13, which fixes the canvas and makes the canvas installation more stable, preventing the canvas from falling off or loosening.
[0047] Example 2
[0048] like Figure 4 As shown, the buffer layer 212 at the corner of the light box differs from the buffer layer 212 in Embodiment 1, which is a buffer airbag structure with honeycomb-shaped air chambers on its surface. When subjected to external impact, the honeycomb-shaped air chambers can quickly absorb and disperse the impact force by utilizing the compressibility of gas and the elasticity of rubber, effectively reducing damage to the light box shell.
[0049] Example 3
[0050] like Figure 5 As shown, the buffer layer 212 at the corner of the lightbox differs from the buffer layer 212 in Embodiment 1, which is a buffer sponge structure. The pores inside the sponge can deform, thereby absorbing and dispersing the impact force. The sponge material is lightweight and inexpensive, making it suitable for lightbox designs that are sensitive to weight and cost.
[0051] Example 4
[0052] like Figure 6 As shown, the buffer layer 212 at the corner of the lightbox differs from that in Embodiment 1. The buffer layer 212 consists of an outer layer and an inner layer, with multiple buffer springs connecting the outer and inner layers. The buffer springs absorb and disperse the impact force through their own compression and extension, and their elastic restoring force can offset the collision force to a certain extent, protecting the internal structure of the lightbox.
[0053] Example 5
[0054] like Figure 7 As shown, Figure 8 As shown, the protective housing 211 at the corner of the lightbox differs from that in Embodiment 1. The protective housing 211 is composed of multiple interconnected modular segments. By adjusting the angle between the modular segments, it can be flexibly adjusted according to the installation environment of the lightbox, making it suitable for corners of irregularly shaped lightboxes.
[0055] Example 6
[0056] like Figure 9 As shown, a protective housing 211 with the lightbox corner design described in Embodiments 1-5 differs from Embodiment 1. The protective housing 211 includes a sleeve 213 and a receiving block 214 that slides circumferentially along the sleeve 213. A connecting post 221 is connected to the side wall of the receiving block 214, and a slot 222 is located on the upper part of the receiving block 214. The sleeve 213 enhances the structural strength of the protective housing 211, and the receiving block 214 is used for the sleeve 213 to engage with the connecting post 221. By sliding and adjusting the position of the receiving block 214 on the sleeve 213, it can adapt to different angles of the lightbox corner, further expanding the applicable range of the lightbox corner design.

[0058] 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.
[0059] 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.
