[0002] As a crucial structure for displaying advertising content, the design and use of billboard frames play a crucial role in the advertising industry. They not only carry the task of conveying advertising information, but also directly affect brand image and marketing effectiveness.

[0003] However, current billboard frames are rigidly structured in practical applications. Many are custom-made to specific billboard sizes and shapes, making them difficult to adjust or modify once they are built. This rigidity limits the versatility and adaptability of billboard frames, making them difficult to meet diverse advertising needs. Therefore, we propose a novel billboard frame. Utility Model Content

[0004] (1) Technical problems solved

[0019] (3) Beneficial effects

[0020] Compared with the prior art, the present invention provides a method with the following beneficial effects:

[0021] 1. This utility model achieves flexible adjustment of the billboard frame length by providing a right extension mechanism. The threaded connection between the screw rod and the mother cylinder in the right extension mechanism allows the right upper frame to move left and right relative to the left upper frame by simply turning the screw rod, thereby adjusting the horizontal length of the billboard. This design is not only simple to operate, but also offers a wide adjustment range, meeting the display requirements of advertising content of different sizes. Furthermore, the provision of a telescopic spring not only provides stable guidance and support for the upper slider, but also, to a certain extent, cushions and adjusts the impact force of the right upper frame during movement, ensuring a smooth and safe adjustment process.

[0022] 2. The present invention achieves flexible adjustment of the billboard frame width by providing left and right width extension mechanisms. The left and right width extension bars are slidably connected to the interior of the left and right upper frames, respectively. By sliding the left and right width extension bars outward or inward, the vertical position of the left and right lower frames relative to the left and right upper frames can be conveniently adjusted, thereby achieving vertical width adjustment of the billboard frame. In addition, the left and right limiting clamping rods, which are threadedly connected to the interior of the left and right concave blocks, can be rotated to press the left and right width extension bars against the bars after they have slid to the desired position, thereby securing the left and right lower frames and ensuring that the billboard frame remains stable at the adjusted width.

[0034] The utility model provides a technical solution:

[0035] See also Figures 1 to 5 The billboard frame includes a left upper frame 1, which is characterized in that a right extension mechanism 2 is provided on the right side of the left upper frame 1.

[0036] The right extension mechanism 2 includes a telescopic spring 21, an upper slide rod 22 is fixedly installed on the right end of the telescopic spring 21, and a right upper frame 23 is fixedly installed on the right end of the upper slide rod 22. Through the elastic action of the telescopic spring 21, the right upper frame 23 can slide and support smoothly on the left upper frame 1, thereby enhancing the flexibility and stability of the billboard frame.

[0037] The right extension mechanism 2 also includes a left basic block 24, a mother cylinder 25 is fixedly installed on the outer side of the left basic block 24, a screw rod 26 is connected to the internal thread of the mother cylinder 25, a bearing 27 is fixedly installed on the right end of the screw rod 26, and a right basic block 28 is fixedly installed on the right side of the bearing 27. By rotating the screw rod 26, the right upper frame 23 can be accurately extended or shortened relative to the left upper frame 1, thereby enhancing the practicality and flexibility of the billboard frame.

[0038] Furthermore, the telescopic spring 21 is fixedly installed inside the left upper frame 1. Through the elastic support of the telescopic spring 21, the vibration and impact force generated when the right upper frame 23 moves can be effectively absorbed and adjusted, thereby improving the stability and durability of the billboard frame.

[0039] Furthermore, the upper slide bar 22 is slidably connected to the left upper frame 1. By setting a precision sliding component, not only the stability and accuracy of the upper slide bar 22 during the sliding process are ensured, but also the stability and reliability of the billboard frame during length adjustment are significantly improved.

[0040] Furthermore, the left foundation block 24 is fixedly mounted on the top of the left upper frame 1 , and the left upper frame 1 provides a mounting position for the left foundation block 24 .

[0041] Furthermore, the right foundation block 28 is fixedly mounted on the top of the right upper frame 23 , and the right upper frame 23 provides a mounting position for the right foundation block 28 .

[0042] Furthermore, a left width extension mechanism 3 is provided at the bottom of the left upper frame 1. The left width extension mechanism 3 includes a left width extension bar 31 slidably connected to the inside of the left upper frame 1. A left lower frame 32 is fixedly installed at the lower end of the left width extension bar 31. The left upper frame 1 is slidably connected to the left width extension bar 31, which ensures the stability and accuracy of the left width extension bar 31 during the sliding process, making the width adjustment smoother and more reliable.

[0043] Furthermore, the left width extension mechanism 3 also includes a left recessed block 33 fixedly mounted on the outside of the left upper frame 1. The internal thread of the left recessed block 33 is connected to a left limiting clamping rod 34. The left limiting clamping rod 34 is combined with the precise thread design to ensure that it can fit tightly with the left width extension strip 31 during rotation, effectively preventing the left lower frame 32 from shaking when subjected to force, thereby improving the overall stability of the billboard frame.

[0044] Furthermore, a right extension mechanism 4 is provided at the bottom of the right upper frame 23. The right extension mechanism 4 includes a right extension bar 41 slidably connected to the inside of the right upper frame 23. A right lower frame 42 is fixedly installed at the lower end of the right extension bar 41. The right extension bar 41 is slidably connected to the inside of the right upper frame 23, which improves the reliability of the billboard frame and makes the size of the billboard frame more stable.

[0045] Furthermore, the right extension mechanism 4 also includes a right recessed block 43 fixedly mounted on the outside of the right upper frame 23. The internal thread of the right recessed block 43 is connected to a right limiting clamping rod 44. Through the coordinated action of the right limiting clamping rod 44 and the right recessed block 43, the position of the right extension strip 41 can be fixed.

[0046] Furthermore, the right lower frame 42 is slidably connected to the inside of the left lower frame 32. By sliding the right lower frame 42 to the inside of the left lower frame 32, it is ensured that the right lower frame 42 slides smoothly and without jamming inside the left lower frame 32, making the width adjustment of the billboard frame more accurate and reliable.

[0047] When used specifically, the working principle of the utility model is as follows:

[0048] Length adjustment principle:

[0049] If the advertising content or display requirements change and the horizontal length of the billboard frame needs to be adjusted, this can be achieved by operating screw rod 26. One end of screw rod 26 is fixed to the right upper frame 23 via bearing 27 and right base block 28, while the other end is threaded into the interior of mother cylinder 25. Mother cylinder 25 is fixedly mounted on the left base block 24 at the top of the left upper frame 1, forming a stable support structure. When screw rod 26 is rotated in the forward direction, it extends outward from mother cylinder 25, pushing the right upper frame 23 to the right. Conversely, rotating screw rod 26 in the reverse direction causes the right upper frame 23 to move to the left. The movement of the right upper frame 23 causes the upper slide bar 22 fixed to it to slide within the left upper frame 1. The right end of the telescopic spring 21 is fixedly connected to the upper slide bar 22, while the left end is fixed to the left upper frame 1. The elastic action of the spring not only provides stable guidance and support for the upper slide bar 22, but also cushions and adjusts the impact of the movement of the right upper frame 23 to a certain extent, ensuring a smooth and safe adjustment process. In particular, the right lower frame 42 can also be slidably connected to the inside of the left lower frame 32. This design further enhances the flexibility and stability of the billboard frame in length adjustment, allowing the entire frame to be precisely adjusted according to advertising content of different sizes.

[0050] Width adjustment principle:

[0051] When the width of the billboard frame needs to be adjusted, it can be achieved by sliding the left extension bar 31 and the right extension bar 41. The left extension bar 31 and the right extension bar 41 are respectively slidably connected to the inside of the left upper frame 1 and the right upper frame 23, and their lower ends are respectively fixedly connected to the left lower frame 32 and the right lower frame 42. When the width of the billboard needs to be increased, the left extension bar 31 and the right extension bar 41 can be slid outward respectively so that the left lower frame 32 and the right lower frame 42 extend outward relative to the left upper frame 1 and the right upper frame 23; conversely, when the width needs to be reduced, the left extension bar 31 and the right extension bar 41 are slid inward. In order to ensure that the adjusted width remains stable, the left extension mechanism 3 and the right extension mechanism 4 are respectively provided with a left concave block 33 and a right concave block 43, and the left limit clamping rod 34 and the right limit clamping rod 44 are threadedly connected thereto. When the left extension bar 31 and the right extension bar 41 slide to the desired position, the left limit pressing rod 34 and the right limit pressing rod 44 are rotated so that they are respectively close to the left extension bar 31 and the right extension bar 41, thereby fixing the left lower frame 32 and the right lower frame 42, thereby ensuring that the billboard frame remains stable at the adjusted width.

[0052] In summary, the billboard frame realizes flexible adjustment of the billboard size through the ingenious design of the length and width adjustment mechanism, meets the diverse advertising display needs, and improves the versatility and adaptability of the billboard frame.

[0053] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention that solve essentially the same technical problems and achieve essentially the same technical effects are included within the scope of protection of the present invention.
