Description

Technical Field

[0001] This utility model relates to the field of light box technology, specifically to a wind-resistant reinforced light box. Background Technology

[0002] Light boxes are used to display product advertisements and convey product information to people. We often see light boxes on the roadside. The structure of these light boxes is mostly simple, generally consisting of a frame, advertising cloth and light tubes. Light tubes are installed inside the frame, and advertising cloth printed with advertising information is wrapped on the outside of the frame. When encountering strong winds, the advertising cloth of existing light boxes often cannot withstand the impact of strong winds and will dent and tear.

[0003] Chinese patent document CN217655651U discloses a stable wind-resistant lightbox. By placing an acrylic sheet inside the frame, the transparent acrylic sheet directly contacts and supports the advertising cloth. When subjected to strong winds, the support of the acrylic sheet greatly reduces the dent of the advertising cloth, improving the stability of the advertising frame and the quality of the advertisement. The transparent acrylic sheet is fixed by a support clamp, which facilitates installation and subsequent maintenance.

[0004] In the above scheme, the support clamp is directly and rigidly connected to the transparent stabilizing plate by bolts. As a result, the vibration and impact energy cannot be effectively absorbed or buffered under wind load, thus generating significant stress concentration at the bolt connection. Over time, the transparent stabilizing plate is very prone to cracks or even breakage due to repeated stress cycles, affecting structural safety and service life. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a wind-resistant and reinforced light box.

[0006] The technical solution of this utility model is as follows: A wind-resistant and reinforced light box includes a main frame and an advertising cloth, as well as a mounting frame and elastic elements. The support frame is set inside the main frame. Multiple transparent support plates that are connected to the advertising cloth and support the advertising cloth in use are inserted and installed on the side of the support frame. There are two elastic elements, which are respectively set on one side of the transparent support plate and connected to the support frame.

[0007] Preferably, the support frame includes transverse support rods and longitudinal support rods, which are connected in a cross-shaped arrangement. Both the transverse and longitudinal support rods are connected to the elastic element and the transparent support plate.

[0008] Preferably, both the transverse support rod and the longitudinal support rod have mounting grooves on their sides, and the width of the mounting grooves is less than the sum of the thicknesses of the two elastic elements and the transparent support plate.

[0009] Preferably, one end of the transparent support plate is tapered.

[0010] Preferably, the end face projection shape of the transparent support plate is T-shaped.

[0011] Preferably, nuts are provided on the sides of both the transverse support rod and the longitudinal support rod, and bolts extending into the elastic element are provided on the inner side of the nuts.

[0012] Preferably, a pressure plate is provided at the end of the bolt, and the pressure plate is connected to the elastic element.

[0013] Preferably, the side of the elastic element is provided with a connecting groove, and when the elastic element and the pressure plate are installed together, the pressure plate is accommodated in the connecting groove.

[0014] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: This utility model, by inserting and installing the transparent support plate on the side of the connecting frame, connects the elastic element to the connecting frame on both sides of the transparent support plate, and limits the transparent support plate in the connecting frame. When the transparent support plate supports the advertising cloth, it absorbs the vibration and impact brought by the wind load, thereby protecting the transparent support plate and ensuring the stability and reliability of the transparent support plate in supporting the advertising cloth under the condition of thermal expansion and contraction.

[0016] Example 1, as Figure 1-4As shown, this utility model proposes a wind-resistant reinforced lightbox, including a main frame 1 and an advertising cloth 2, as well as a mounting frame and elastic elements 8. The support frame is located inside the main frame 1 and consists of transverse support rods 3 and longitudinal support rods 4. The transverse support rods 3 and longitudinal support rods 4 are connected in a cross shape inside the main frame 1, making the main frame 1 have a grid-like arrangement. This increases the number of support positions inside the main frame 1, thereby improving the wind resistance of the advertising cloth 2. Transparent support plates 9 are inserted and installed on the sides of both the transverse support rods 3 and the longitudinal support rods 4, which are connected to the advertising cloth 2 and support the advertising cloth 2 in use. There are multiple elastic elements 8, and each pair of elastic elements 8 is connected to the advertising cloth 2. Each set consists of two elastic elements 8, each set being installed on one side of the transparent support plate 9 and connected to the horizontal support rod 3 or the vertical support rod 4. The elastic elements 8 are made of materials such as rubber, silicone, or closed-cell foam and are used to absorb vibrations and impacts from wind loads during use to protect the transparent support plate 9. When the plate expands due to heat, it will compress the elastic elements 8. When it cools and contracts, the rebound force of the elastic elements 8 can maintain the clamping state, ensuring the stability and reliability of the transparent support plate 9 under thermal expansion and contraction. The transparency of the transparent support plate 9 should be such that it does not block light. Tempered glass, acrylic sheet, and polycarbonate sheet can be selected for use. Acrylic sheet is the best choice for improving on-site installation convenience.

[0017] In an optional embodiment, both the transverse support rod 3 and the longitudinal support rod 4 are provided with mounting grooves 10 on their sides. The width of the mounting groove 10 is less than the sum of the thicknesses of the two elastic members 8 and the transparent support plate 9. When the two elastic members 8 are installed inside the mounting groove 10, the elastic members 8 are compressed and contracted through the cooperation between the transparent support plate 9 and the mounting groove 10, so that the transparent support plate 9 is limited inside the mounting groove 10 by the elastic members 8. When the advertising cloth 2 is connected to the main frame 1, the advertising cloth 2 contacts the end of the transparent support plate 9 and further limits the transparent support plate 9, so that the transparent support plate 9 provides stable support for the advertising cloth 2 inside the mounting groove 10.

[0018] In an optional embodiment, one end of the transparent support plate 9 is tapered, which is used to place the elastic element 8 inside the mounting groove 10 first and install one end of the pressure plate 7 between the two elastic elements 8 into the mounting groove 10 during use, making the installation of the transparent support plate 9 more convenient.

[0019] In this embodiment, mounting grooves 10 are provided on the sides of the transverse support rod 3 and the longitudinal support rod 4. During installation, two elastic members 8 are first placed inside the mounting groove 10, and a transparent support plate 9 is inserted between the two elastic members 8 into the mounting groove 10. When the transparent support plate 9 is placed inside the mounting groove 10, it cooperates with the mounting groove 10 to apply pressure to the elastic members 8, so that the two elastic members 8 initially limit the transparent support plate 9 in the mounting groove 10. Subsequently, when the advertising cloth 2 is installed on the main frame 1, the advertising cloth 2 and the transparent support plate 9... The end contact and constraint on the position of the transparent support plate 9 in the mounting groove 10 make the installation of the transparent support plate 9 more convenient. At the same time, when the transparent support plate 9 acts as a back support for the advertising cloth 2, the elastic element 8 can effectively absorb the vibration and impact generated by the wind load, thereby protecting the transparent support plate 9 from damage. The elastic element 8 is located on both sides of the transparent support plate 9, which allows the transparent support plate 9 to maintain stable and reliable support for the advertising cloth 2 under thermal expansion and contraction, ensuring the wind resistance effect of the advertising cloth 2 under wind load conditions.

[0020] Example 2, as Figure 4 As shown, the present invention proposes a wind-resistant reinforced light box. Compared with the first embodiment, the difference in this embodiment is that the end face projection shape of the transparent support plate 9 is T-shaped, which is used to increase the contact area between the transparent support plate 9 and the advertising cloth 2 during use, thereby further improving the wind resistance of the advertising cloth 2 and increasing the strength of the transparent support plate 9.

[0021] In this embodiment, the transparent support plate 9 has a T-shaped projection shape on its end face, which makes the contact area between the transparent support plate 9 and the advertising cloth 2 large after installation. As a result, when the wind blows towards the advertising cloth 2, the transparent support plate 9 provides large-area support for the advertising cloth 2, thereby improving the wind resistance of the advertising cloth 2.

[0022] Example 3, as Figure 2-3 As shown, the wind-resistant reinforced light box proposed in this utility model differs from Embodiment 1 in that nuts 6 are welded to the sides of both the transverse support rod 3 and the longitudinal support rod 4. Bolts 5 extending towards the elastic element 8 are installed on the inner side of the nuts 6. A pressure plate 7 is provided at the end of the bolt 5. The pressure plate 7 is connected to the elastic element 8 and is used to increase the area on which the bolt 5 and the nut 6 apply force to the elastic element 8 during use, thereby increasing the area on which the transparent support plate 9 is pressed and limited, and thus improving the stability of the transparent support plate 9 installed between the two elastic elements 8.

[0023] In an optional embodiment, the side of the elastic member 8 is provided with a connecting groove 11. When the elastic member 8 and the pressure plate 7 are installed together, the pressure plate 7 is accommodated in the connecting groove 11. This is to prevent the thickness of the elastic member 8 from decreasing during use, so that the pressure plate 7 applies pressure to the elastic member 8 on the inside of the connecting groove 11 and causes the pressure plate 7 to drive the elastic member 8 to press and fix the transparent support plate 9, making the installation of the transparent support plate 9 more stable.

[0024] In this embodiment, by tightening the bolt 5 in the nut 6, the end of the bolt 5 moves toward the elastic member 8, thereby causing the bolt 5 to apply pressure to the pressure plate 7 inside the connecting groove 11, and the pressure plate 7 transmits the pressure to the elastic member 8, so that the pressure plate 7 drives the elastic member 8 to squeeze the transparent support plate 9 over a large area, so that the transparent support plate 9 is fixed inside the transverse support rod 3 and the longitudinal support rod 4, thereby improving the stability of the installation of the transparent support plate 9.

[0025] In this invention, the transverse support rod 3 and the longitudinal support rod 4 are arranged in a cross shape inside the main frame 1, and mounting grooves 10 are provided on the sides of the transverse support rod 3 and the longitudinal support rod 4. During installation, two elastic members 8 are first placed inside the mounting groove 10, and a transparent support plate 9 is inserted between the two elastic members 8 into the mounting groove 10. When the transparent support plate 9 is placed inside the mounting groove 10, it cooperates with the mounting groove 10 to apply pressure to the elastic members 8, so that the two elastic members 8 initially limit the transparent support plate 9 in the mounting groove 10. At the same time, the bolt 5 is tightened in the nut 6, so that the end of the bolt 5 moves towards the elastic member 8, thereby causing the bolt 5 to apply pressure to the pressure plate 7 inside the connecting groove 11, and causing the pressure plate 7 to transmit the pressure to the elastic member 8, so that the pressure plate 7 drives the elastic member 8 to... The transparent support plate 9 is compressed over a large area, fixing it to the inside of the transverse support rod 3 and the longitudinal support rod 4. Subsequently, when the advertising cloth 2 is installed onto the main frame 1, the advertising cloth 2 contacts the end of the transparent support plate 9, constraining the position of the transparent support plate 9 within the mounting groove 10, making the installation of the transparent support plate 9 more convenient. At the same time, the transparent support plate 9 supports the back of the advertising cloth 2, and the elastic element 8 can effectively absorb the vibration and impact generated by the wind load, thereby protecting the transparent support plate 9 from damage. Furthermore, the elastic element 8 is located on both sides of the transparent support plate 9, allowing the transparent support plate 9 to maintain stable and reliable support for the advertising cloth 2 even under thermal expansion and contraction, ensuring the wind resistance effect of the advertising cloth 2 under wind load conditions.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
