Description

Technical Field

[0001] This utility model relates to the field of profile technology, and in particular to a lightbox profile and a nine-grid advertising lightbox. Background Technology

[0002] Profiles are typically connected using planar contact, but this method limits the contact area between the profile body and its corresponding components. According to the principle of friction, the magnitude of friction is related to the contact area and the coefficient of friction. With a fixed coefficient of friction, the limited contact area results in relatively low friction between the profile body and its corresponding components. This makes the profile body prone to spontaneous movement under external forces or during long-term use, affecting the stability and reliability of the entire structure and potentially leading to safety accidents. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides a light box profile and a nine-square grid advertising light box. By setting a wavy groove on the second connecting boss, the wavy groove increases the contact area between the profile body and the corresponding parts, increases the friction between the profile body and the corresponding parts, reduces the risk of the profile body moving on its own, and ensures that the connection between the profile body and the corresponding parts is more secure.

[0004] When installing the profile bodies together, adjust them along the length of the profile bodies until they are installed in the corresponding positions.

[0005] Accordingly, this utility model proposes a lightbox profile, which includes: a profile body;

[0006] One side of the profile body extends outward to form a snap-fit ​​portion, the snap-fit ​​portion including a plurality of first connecting bosses, each of the first connecting bosses having a first snap-fit ​​boss;

[0007] The bottom of the profile body on the opposite side of the snap-fit ​​portion extends outward to form a connecting portion. The connecting portion includes a plurality of second connecting bosses, each of which is recessed to form a wavy groove.

[0008] In some specific embodiments, the top of the profile body on the opposite side of the snap-fit ​​portion is recessed inward to form a snap-fit ​​groove, and the end face of the snap-fit ​​groove is provided with a second snap-fit ​​protrusion.

[0009] In some specific embodiments, the profile body has a hollow cavity.

[0010] In some specific embodiments, a connecting plate is provided on the profile body, and the connecting plate is distributed along the length direction of the profile body.

[0011] In some specific embodiments, the light box profile is made of metal or plastic.

[0012] This utility model also proposes a nine-square grid advertising light box, which includes multiple of the above-mentioned profile bodies, and the multiple profile bodies are spliced ​​together to form a nine-square grid.

[0013] The beneficial effects of this utility model are:

[0014] This invention features a wave-shaped protrusion on the second connecting protrusion of the lightbox profile. The wave-shaped groove increases the contact area between the profile body and the corresponding component, increases the friction between the profile body and the corresponding component, reduces the risk of the profile body moving on its own, and ensures a more secure connection between the profile body and the corresponding component. Furthermore, this invention includes a snap-fit ​​part with two first snap-fit ​​protrusions. These two first snap-fit ​​protrusions can snap into the positions of the corresponding components, making the connection between the corresponding components and the profile body more secure. This effectively withstands various external forces, such as wind and vibration, experienced by the doors and windows during use, ensuring the structural stability and service life of the door and window frame.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Figure 1 A schematic diagram of the structure of the light box profile in this utility model is shown. Figure 2 A cross-sectional view of the lightbox profile of this utility model is shown. Figure 3 It shows Figure 2 Enlarged view of point A in the image. Figure 4 The diagram shows a front view of the nine-grid advertising lightbox of this invention. The lightbox profile includes: a profile body 1; a snap-fit ​​portion 11 extending outward from one side of the profile body 1, the snap-fit ​​portion 11 including a plurality of first connecting protrusions 111, each first connecting protrusion 111 having a first snap-fit ​​protrusion 1111; and a connecting portion 12 extending outward from the bottom of the other side of the profile body 1 opposite to the snap-fit ​​portion 11, the connecting portion 12 including a plurality of second connecting protrusions 121, each second connecting protrusion 121 having a wavy groove 122 recessed therein. The snap-fit ​​portion 11 includes two first connecting protrusions 111, each first connecting protrusion 111 having a first snap-fit ​​protrusion 1111, the two first snap-fit ​​protrusions 1111 being located on opposite sides of the two first connecting protrusions 111, and the two first snap-fit ​​protrusions 1111 being aligned with the straight line of the center of the snap-fit ​​portion 11. The two first engaging protrusions 1111 can engage with the corresponding components, making the connection between the corresponding components and the profile body 1 more secure. This effectively withstands various external forces encountered by the doors and windows during use, such as wind and vibration, ensuring the structural stability and service life of the door and window frame. The second connecting protrusion 121 is provided with a wavy groove 122. When the wavy groove 122 is connected to the corresponding component, it increases the contact area between the profile body 1 and the corresponding component, increases the friction between the profile body 1 and the corresponding component, reduces the risk of the profile body 1 moving on its own, and ensures a more secure connection between the profile body 1 and the corresponding component.

[0023] Furthermore, the top of the side opposite to the snap-fit ​​part 11 of the profile body 1 is recessed inward to form a snap-fit ​​groove 13, and the end face of the snap-fit ​​groove 13 is provided with a second snap-fit ​​protrusion 131. In this embodiment, each of the two end faces of the snap-fit ​​groove 13 is provided with a second snap-fit ​​protrusion 131, and the two second snap-fit ​​protrusions 131 face inward to the inside of the snap-fit ​​groove 13. When the profile body 1 is snapped with the corresponding component, the corresponding component can move along the snap-fit ​​groove 13, and the two second snap-fit ​​protrusions 131 will abut against the position of the corresponding component. The two second snap-fit ​​protrusions 131 are snapped into the corresponding groove, making the connection between the corresponding component and the profile body 1 more secure, and can effectively withstand various external forces, such as wind and vibration, during the use of the door and window, ensuring the structural stability and service life of the door and window frame. Through this unique snap-fit ​​structure design, the assembly between the profile bodies 1 does not require the use of additional connectors and tools, which greatly improves the assembly efficiency and reduces the assembly cost.

[0024] Furthermore, the profile body 1 has a hollow cavity 10. The design of the hollow cavity 10 in the profile body 1 makes the profile relatively lightweight, reducing its weight without significantly reducing its strength, thus facilitating installation and debugging. The hollow cavity 10 can serve as a wiring channel for the equipment, concealing wires and cables inside the profile, resulting in a cleaner and more aesthetically pleasing appearance. It also prevents external interference and damage to the wires and cables, improving the safety and reliability of the equipment. During equipment operation, the profile generates heat. The presence of the hollow cavity 10 increases the surface area of ​​the profile, facilitating heat dissipation and improving its heat dissipation performance, ensuring the normal operation of the equipment.

[0025] Furthermore, a connecting plate 14 is provided on the profile body 1, and the connecting plate 14 is distributed along the length direction of the profile body 1. The connecting plate 14 is also made of aluminum alloy, the same material as the profile body 1, which ensures good welding performance and connection strength between the two, and avoids problems such as electrochemical corrosion caused by material differences. The four corners of the connecting plate 14 are designed with rounded corners, which can prevent cracks caused by stress concentration during processing and use, and improve the strength and reliability of the connecting plate 14.

[0026] It should be noted that the connecting plate 14 can be a straight plate of the same length as the profile body 1. A long straight plate can provide continuous support for the profile body 1, and when subjected to external force, it can evenly distribute the force across the entire profile, effectively reducing local stress concentration. Similarly, the connecting plate 14 can also be multiple straight plates of shorter length, reducing material waste and lowering manufacturing costs.

[0027] Furthermore, the material of the lightbox profile is either metal or plastic. In this embodiment, when the lightbox profile is metal, it can be aluminum alloy or other lightweight alloys. Aluminum alloys have advantages such as low density, high strength, and good corrosion resistance, which can meet the usage requirements of lightboxes in different environments. At the same time, its good processing performance makes it easy to manufacture profiles of various complex shapes. When the lightbox profile is plastic, the density of plastic is usually much lower than that of metal, making the plastic lightbox profile lighter. During installation and transportation, the lightweight plastic profile can reduce labor intensity and lower transportation costs. Simultaneously, for some lightboxes that need to be suspended or moved, such as advertising lightboxes and display lightboxes, the lightweight characteristic makes them easier to operate and install, improving ease of use. Plastic is a good insulating material with excellent electrical insulation properties. In lightboxes, using plastic profiles can effectively prevent safety problems such as current leakage and short circuits, improving the electrical safety of the lightbox.

[0028] This utility model also proposes a nine-square grid advertising light box 100, which includes multiple profile bodies 1 as described above, and the multiple profile bodies 1 are spliced ​​together to form a nine-square grid. In this embodiment, the nine-square grid advertising light box 100 includes eight profile bodies 1, and the eight profile bodies 1 are spliced ​​together to form a nine-square grid advertising light box. Nine light panels are installed in the nine-square grid advertising light box to form an aesthetically pleasing advertising light box.

[0029] In summary, this utility model, by setting a wave-shaped boss on the second connecting boss of the light box profile, can increase the contact area between the profile body and the corresponding component, increase the friction between the profile body and the corresponding component, reduce the risk of the profile body moving on its own, and ensure a more secure connection between the profile body and the corresponding component. Furthermore, by setting a snap-fit ​​part with two first snap-fit ​​bosses, this utility model can snap into the position of the corresponding component, making the connection between the corresponding component and the profile body more secure. This effectively withstands various external forces, such as wind and vibration, that the doors and windows experience during use, ensuring the structural stability and service life of the door and window frame.

[0030] Furthermore, the above description provides a detailed introduction to a lightbox profile and a nine-grid advertising lightbox provided by the embodiments of this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
