Technical Field

[0001] This utility model relates to the field of billboard frame technology, specifically to a billboard frame and a billboard. Background Technology

[0002] Billboards are visual display media that are placed in various corners of the city to convey advertising information. They exist in different forms, materials and designs in commercial districts, along highways, on building facades, etc., and are an important part of the urban landscape, while also playing an important commercial role.

[0003] A Chinese patent (CN110397341A) discloses a method for manufacturing a billboard frame for construction site fencing. The method involves manufacturing a stainless steel rectangular frame and then manufacturing the billboard, which is fitted to the rectangular frame. The billboard is fixed to the construction site fencing with an opening on the right side. The billboard is inserted into a movable rod and secured. The billboard, along with the movable rod, is inserted into the side-opening ∏ structure from the right-side opening. This invention provides a simple, convenient, standardized, and practical billboard manufacturing method for construction site fencing, offering advantages such as replaceability and cost savings on construction measures. Based on the billboard's design dimensions, a corresponding rectangular frame is manufactured using ∏-shaped stainless steel profiles. The upper and lower rods of the rectangular frame are welded and fixed to the left-side rod, forming the ∏ structure with an opening on the right side. The right-side rod of the rectangular frame is an independent movable rod, capable of being assembled with the ∏ structure to form the rectangular frame. The width between the two legs of the ∏-shaped stainless steel profile is 5mm, and the leg height is 20mm. The stainless steel material is 200 series stainless steel, and the thickness of the stainless steel profile is 2mm. The joints between the upper and lower rods of the Ώ structure and the independent movable rod are each designed with a 45-degree bevel.

[0004] In the existing technology, the frames of outdoor storefront billboards are mostly welded on-site, which is quite troublesome to install, or they are transported and hoisted for installation after being welded by the manufacturer.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a billboard frame, comprising: a keel 1 and a central rectangular frame 4. The keel 1 serves as the main supporting structure of the billboard frame, bearing the weight of the entire frame and securely fixing it in its installation position. Its design is robust and durable, resisting erosion from natural factors such as wind and rain, ensuring the stability of the billboard. The arrangement of the keel 1 is typically customized according to the size and shape of the billboard to meet different installation requirements.

[0022] A fixing rod 5 is provided on one side of the keel 1. There are multiple fixing rods 5, which are fixed to the keel 1. A central rectangular frame 4 is provided on the fixing rod 5 located in the middle of the keel 1, and edge rectangular frames 4 are provided on the fixing rods 5 located at both ends of the keel 1. The edge rectangular frames 3 are located on the periphery of the billboard frame, serving to define the boundary of the billboard and protect the internal frame. Together with the central rectangular frame 4, they form a complete advertising display area. The design of the edge rectangular frames 3 usually takes into account aesthetics and durability to enhance the overall visual effect and service life of the billboard.

[0023] The fixing rod 5 has a rod sleeve 6 on its outer side. The fixing rod 5 is set along the length of the keel 1 and is used to hang the edge rectangular frame 3 and the central rectangular frame 4. They are firmly fixed to the keel 1 by specific fixing methods such as welding, ensuring the stability and safety of the frame assembly. The number and position of the fixing rods 5 are reasonably configured according to the size and weight distribution of the billboard.

[0024] The top of the sleeve 6 is equipped with a pressure plate 7, and the fixing rod 5 has fixing ears 9 on both sides. The pressure plate 7, located at the top of the sleeve 6, is used to firmly press the edge rectangular frame 3 and the central rectangular frame 4 onto the fixing rod 5, preventing them from shaking or falling off during use. The pressure plate 7 is designed with sufficient rigidity and friction to ensure the stability of the frame assembly. A fixing screw 8 is located on one side of the keel 1, outside the fixing ear 9, and a locking nut 10 is located outside the fixing screw 8. The fixing screw 8 passes through the fixing ear 9 and engages with a corresponding structure on the sleeve 6 to lock the position of the pressure plate 7. By rotating the locking nut 10, the tightness of the fixing screw 8 can be adjusted, thereby achieving a secure fixation of the pressure plate 7 and the frame assembly. The design of the fixing screw 8 makes the assembly process simpler and faster.

[0025] During the billboard frame fabrication, the entire frame is divided into several edge rectangular frames 3 and several central rectangular frames 4 according to the billboard's dimensions. The disassembled frame is easier to transport. During on-site assembly, the keel 1 is fixed to the wall above the entrance using connecting plates 2 and expansion bolts. Then, the edge rectangular frames 3 and several central rectangular frames 4 are hung on the fixing rod 5. The rod sleeve 6 is then pushed so that the pressure plate 7 on the rod sleeve 6 abuts against the edge rectangular frames 3 or the central rectangular frames 4. Finally, the position of the pressure plate 7 is locked with the locking nut 10, thus assembling the frame without the need for on-site welding, making the entire billboard frame fabrication, transportation, and assembly more convenient.

[0026] There are multiple keels 1, with keels 1 installed at the top and bottom of the central rectangular frame 4. The multiple keels 1 are distributed along the billboard frame, forming a series of parallel support structures.

[0027] The top of the keel 1 is equipped with a connecting plate 2, which has through holes for connecting expansion bolts to the wall. The connecting plate 2 is used to connect the keel 1 to the wall above the door, and is fixed with expansion bolts to ensure that the keel 1 is stable and does not wobble. The design of the connecting plate 2 makes the installation process simpler, and also enhances the connection strength between the keel and the wall.

[0028] The fixing lug 9 has a through hole inside, located outside the fixing screw 8, for the fixing screw 8 to pass through. The through hole inside the fixing lug 9 is specifically designed for the fixing screw 8, ensuring that the screw can pass through smoothly and be fixed in the predetermined position.

[0029] There are multiple central rectangular frames 4, and the external dimensions of these multiple central rectangular frames 4 and the edge rectangular frames 3 match the dimensions of the billboard. The external dimensions of the multiple central rectangular frames 4 and the edge rectangular frames 3 are designed to match the dimensions of the billboard, meaning that the frame components can be perfectly assembled to fit the billboard's outline. Because the external dimensions of the central rectangular frames 4 and the edge rectangular frames 3 match the billboard dimensions, they can be flexibly combined and adjusted according to the specific dimensions and requirements of the billboard.

[0030] Example 2: Please refer to Figures 1-4 This utility model provides a technical solution: a billboard, including the billboard frame of Embodiment 1, with a covering material such as inkjet cloth installed on the outside of the billboard frame.

[0031] During the billboard frame fabrication, the entire frame is divided into several edge rectangular frames 3 and several central rectangular frames 4 according to the billboard's dimensions. The disassembled frame is easier to transport. During on-site assembly, the keel 1 is fixed to the wall above the entrance using connecting plates 2 and expansion bolts. Then, the edge rectangular frames 3 and several central rectangular frames 4 are hung on the fixing rod 5. The rod sleeve 6 is then pushed so that the pressure plate 7 on the rod sleeve 6 abuts against the edge rectangular frames 3 or the central rectangular frames 4. Finally, the position of the pressure plate 7 is locked with the locking nut 10, thus assembling the frame without the need for on-site welding, making the entire billboard frame fabrication, transportation, and assembly more convenient.

[0032] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
