Description

Technical Field

[0001] This utility model relates to the field of graphic display board fixing technology, specifically a graphic display board fixing frame. Background Technology

[0002] In the field of modern information display, graphic display boards serve as an important medium for conveying information and are widely used in exhibitions, bulletin boards, and event promotions. To ensure the stable display of graphic display boards, a fixed frame serves as its supporting structure, typically composed of rods and connectors. The display board is secured by constructing the main frame to achieve effective information presentation. While existing graphic display board fixed frames primarily function to provide support for the display board, many issues remain that require improvement in structural design and practical application.

[0003] Currently, traditional graphic display board fixing frames generally suffer from the following shortcomings: First, their structural stability is poor. Most use linear supports or simple frame structures, lacking geometrically stable designs such as triangles, making them prone to swaying or even tipping over when subjected to external impacts or wind. Second, they lack bottom counterweights and anti-slip designs. Most frames use stones to weigh down their four corners to further ensure stability, but the weight of the stones is fixed and cannot be flexibly adjusted, making it difficult to adapt to different wind conditions or ground environments. Furthermore, the stones must be carried separately when transporting the entire frame, increasing the transportation burden; and exposed stones are not only unsightly but may also cause imbalance due to accidental displacement, thus weakening stability. Therefore, a new graphic display board fixing frame is urgently needed to solve these problems. Utility Model Content

[0004] In view of the shortcomings of the prior art mentioned in the background, the present invention provides a fixed frame for graphic display boards.

[0005] This utility model overcomes the above technical problems by adopting the following technical solution:

[0006] A graphic display board fixing frame includes a base rod, a crossbar fixedly connected to one side of the outer wall of the base rod, and the other end of the crossbar fixedly connected to another base rod. A first rotating seat and a second rotating seat are fixedly connected to the top outer wall of the base rod respectively. A first rotating column is rotatably connected to one side of the first rotating seat, and a second rotating column is rotatably connected to one side of the second rotating seat. A first support rod is fixedly connected to the outer circumference of the first rotating column, and a second support rod is fixedly connected to the outer circumference of the second rotating column. A display board is fixedly connected to one side of the first support rod, and a locking rod is fixedly connected to the end of the second support rod away from the second rotating column. A locking groove that mates with the locking rod is provided at one end of the first support rod. The base rod, the second support rod, and the first support rod form a triangular structure.

[0007] Preferably, a horizontal column is fixedly connected to one side of the outer wall of the first support rod, and the other end of the horizontal column is fixedly connected to one side of the outer wall of another first support rod. A handle is fixedly connected to the circumferential outer wall of the horizontal column.

[0008] Preferably, a base plate box is fixedly connected to the bottom outer wall of the base rod. The base plate box contains clean water. A water injection hole is opened on the top outer wall of the base plate box. A sealing plug is snapped into the water injection hole. An elastic strip is fixedly connected to the top outer wall of the sealing plug. The other end of the elastic strip is fixedly connected to the top outer wall of the base plate box. A drain pipe is inserted into one side outer wall of the base plate box. A sealing cap is threaded to one end of the drain pipe.

[0009] Preferably, a fixed seat is fixedly connected to one outer wall of the base rod, and a rotating shaft is rotatably connected to both inner walls of the fixed seat. A fixed column is fixedly connected to the outer circumference of the rotating shaft, and a roller is fixedly connected to the bottom end of the fixed column. A baffle for limiting the rotation of the fixed column is fixedly connected to the inner top wall of the base rod.

[0010] Preferably, the bottom outer wall of the base plate box is fixedly connected to an anti-slip plate, and the bottom outer wall of the anti-slip plate is provided with anti-slip grooves distributed at equal intervals.

[0011] Preferably, a limiting plate for rotating and limiting the second support rod is fixedly connected to the top outer wall of the base plate box, and one side of the limiting plate abuts against one side outer wall of the second support rod.

[0012] Preferably, the interior of the first rotating seat is provided with a threaded hole and a through hole, the through hole and the threaded hole are connected, and a threaded rod is threadedly connected in the threaded hole. The two ends of the threaded rod are respectively fixedly connected to a limit post and a rotating block. The outer circumferential wall of the limit post abuts against the outer wall of one side of the first support rod, and the diameter of the limit post is larger than the diameter of the threaded rod.

[0013] By adopting the above structure, this utility model has the following advantages compared with the prior art: The triangular stable structure formed by the base rod, the first support rod, and the second support rod effectively improves the overall stability of the frame and prevents the display board from shaking or tipping over due to external forces. At the same time, the bottom plate box at the bottom of the base rod can be filled with water to increase the counterweight. Combined with the bottom anti-slip plate and anti-slip groove, it further enhances the anti-tipping ability and ground friction. Moreover, the limiting plate at the top of the bottom plate box abuts against the second support rod, which not only restricts its excessive rotation and ensures the accuracy of the triangular structure angle, avoiding the instability of the frame caused by the support angle deviation, but also facilitates the staff to quickly and easily connect and fix the first support rod and the second support rod, improving the installation efficiency of the entire fixed frame.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 7In this embodiment of the utility model, a graphic display board fixing frame includes a base rod 21. A crossbar 22 is fixedly connected to one outer wall of the base rod 21, and the other end of the crossbar 22 is fixedly connected to another base rod 21. A first rotating seat 4 and a second rotating seat 9 are fixedly connected to the top outer wall of the base rod 21. A first rotating column 3 is rotatably connected to one side of the first rotating seat 4, and a second rotating column 14 is rotatably connected to one side of the second rotating seat 9. A first support rod 1 is fixedly connected to the outer circumferential wall of the first rotating column 3, and a second support rod 14 is fixedly connected to the outer circumferential wall of the second rotating column 14. The support rod 10 has a display panel 2 fixedly connected to one side of the first support rod 1, and a locking rod 11 fixedly connected to the end of the second support rod 10 away from the second rotating column 14. One end of the first support rod 1 has a slot that cooperates with the locking rod 11. The bottom rod 21, the second support rod 10 and the first support rod 1 form a triangular structure. The bottom rod 21, the first support rod 1 and the second support rod 10 constitute a triangular stable structure. By utilizing the geometric stability of the triangle, the frame can be effectively resisted from shaking caused by external forces, ensuring that the display panel 2 remains stable during use and preventing it from tipping over due to collisions or wind.

[0024] Furthermore, a horizontal column 12 is fixedly connected to one side of the outer wall of the first support rod 1, and the other end of the horizontal column 12 is fixedly connected to one side of the outer wall of another first support rod 1. A handle 13 is fixedly connected to the circumferential outer wall of the horizontal column 12 to facilitate the displacement of the entire fixed frame.

[0025] Furthermore, a base plate box 5 is fixedly connected to the bottom outer wall of the base rod 21. The base plate box 5 contains clean water. A water injection hole is opened on the top outer wall of the base plate box 5. A sealing plug 7 is snapped into the water injection hole. An elastic strip 8 is fixedly connected to the top outer wall of the sealing plug 7. The other end of the elastic strip 8 is fixedly connected to the top outer wall of the base plate box 5. A drain pipe 6 is inserted into one side outer wall of the base plate box 5. A sealing cap is threaded to one end of the drain pipe 6. Workers can inject clean water into the base plate box 5. When injecting water, the sealing plug 7 is opened. The elastic strip 8 is connected to the sealing plug 7 to prevent loss. The weight of the water can increase the counterweight at the bottom of the frame and improve the anti-overturning ability, which is suitable for outdoor windy scenes.

[0026] Furthermore, a fixed seat 19 is fixedly connected to one outer wall of the base rod 21. A rotating shaft 27 is rotatably connected to both inner walls of the fixed seat 19. A fixed column 24 is fixedly connected to the outer circumference of the rotating shaft 27. A roller 20 is fixedly connected to the bottom end of the fixed column 24. A baffle 25 for limiting the rotation of the fixed column 24 is fixedly connected to the inner top wall of the base rod 21. When the staff needs to move the frame, they pull the roller 20 down. At this time, the fixed column 24 at the top of the roller 20 will rotate with the rotating shaft 27 until the roller 20 contacts the ground. During the process of pulling the roller 20, the baffle 25 can effectively limit the rotation angle of the fixed column 24, avoiding the situation where the roller 20 rotates excessively and cannot make vertical contact with the ground.

[0027] Furthermore, an anti-slip plate 15 is fixedly connected to the bottom outer wall of the base plate box 5. The bottom outer wall of the anti-slip plate 15 is provided with anti-slip grooves distributed at equal intervals. The anti-slip plate 15 at the bottom of the base plate box 5 is in close contact with the ground through the anti-slip grooves to increase friction and prevent the frame from sliding.

[0028] Furthermore, a limiting plate 23 for rotating and limiting the second support rod 10 is fixedly connected to the top outer wall of the base plate box 5. One side of the limiting plate 23 abuts against one side outer wall of the second support rod 10. The limiting plate 23 at the top of the base plate box 5 abuts against the second support rod 10, which not only restricts its excessive rotation and ensures the accuracy of the triangular structure angle, avoiding the instability of the frame caused by the support angle deviation, but also facilitates the workers to quickly snap and fix the first support rod 1 and the second support rod 10, improving the installation efficiency of the entire fixed frame.

[0029] Furthermore, the interior of the first rotating seat 4 is provided with a threaded hole and a through hole 26. The through hole 26 is connected to the threaded hole. A threaded rod 17 is threadedly connected to the threaded hole. The two ends of the threaded rod 17 are fixedly connected to a limit post 16 and a rotating block 18, respectively. The outer circumference of the limit post 16 is pressed against the outer wall of one side of the first support rod 1. After the frame is installed and clean water is injected into the base box 5, the operator can rotate the rotating block 18. The rotating block 18 drives the screw to rotate together. Through the threaded connection between the threaded rod 17 and the threaded hole, the threaded rod 17 can drive the limit post 16 to move horizontally together until the limit post 16 moves to one side of the first support rod 1. At this time, the outer circumference of the limit post 16 contacts the outer wall of one side of the first support rod 1, which can play a role in limiting and reinforcing the first support rod 1. The diameter of the limit post 16 is larger than the diameter of the threaded rod 17, which can play a limiting role and prevent the operator from excessively rotating the threaded rod 17, causing the limit post 16 to move out of the threaded hole and be lost.

[0030] Working principle: In this device, a rectangular basic frame is formed by welding the bottom rod 21 and the cross rod 22. When it is necessary to set up the display board, the operator rotates the first rotating column 3 and the second rotating column 14, so that the first support rod 1 and the second support rod 10 unfold around the rotating seat as the axis. The locking rod 11 at the end of the second support rod 10 is inserted into the locking groove of the first support rod 1. At this time, the bottom rod 21, the first support rod 1 and the second support rod 10 form a triangular stable structure. By utilizing the geometric stability of the triangle, the frame shaking caused by external forces can be effectively resisted, ensuring that the display board 2 remains stable during use and avoiding tipping over due to collision or wind.

[0031] When the staff needs to move the frame, they can pull down the roller 20. At this time, the fixed column 24 at the top of the roller 20 will rotate with the rotating shaft 27 until the roller 20 contacts the ground. During the process of pulling the roller 20, the baffle 25 can effectively limit the rotation angle of the fixed column 24, so as to avoid the roller 20 from rotating too much and failing to make vertical contact with the ground. When the entire frame reaches the designated position, the roller 20 is flipped up and stored. The anti-slip plate 15 at the bottom of the base box 5 is in close contact with the ground through the anti-slip groove, increasing the friction and preventing the frame from sliding. At the same time, the staff can inject clean water into the base box 5. When injecting water, the sealing plug 7 is opened. The elastic strip 8 connects the sealing plug 7 to prevent loss. The weight of the water can increase the counterweight at the bottom of the frame and improve the anti-overturning ability, which is suitable for outdoor windy scenes.

[0032] After the frame is installed and clean water is injected into the base box 5, the operator can rotate the rotating block 18. The rotating block 18 drives the screw to rotate as well. Through the threaded connection between the threaded rod 17 and the threaded hole, the threaded rod 17 can drive the limiting post 16 to move horizontally until the limiting post 16 moves to one side of the first support rod 1. At this time, the outer circumference of the limiting post 16 contacts the outer side of one side of the first support rod 1, which can limit and reinforce the first support rod 1. In addition, the limiting plate 23 at the top of the base box 5 presses against the second support rod 10, which can not only limit its excessive rotation and ensure the accuracy of the triangular structure angle, avoiding the instability of the frame caused by the support angle deviation, but also facilitate the operator to quickly snap and fix the first support rod 1 and the second support rod 10, improving the installation efficiency of the entire fixed frame.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
