Description

Technical Field

[0001] This utility model relates to the field of exhibition hall display technology, and in particular to a multi-section expandable exhibition hall display device. Background Technology

[0002] In the current exhibition and display field, traditional exhibition display devices typically employ fixed sizes and structural designs, making it difficult to change the screen size, splicing method, and display scale after installation. This fixed format presents numerous limitations when facing exhibitions of varying sizes and diverse content requirements. For example, in large exhibitions, insufficient screen size leads to incomplete information display, while in small exhibitions, oversized display devices result in resource waste and negatively impact the display effect. To address these issues, a multi-section, expandable exhibition display device has emerged. Through modular design, this device allows for flexible adjustment of the display scale and splicing method according to actual exhibition needs, effectively enhancing the adaptability and flexibility of exhibition displays.

[0003] In existing technologies, exhibition hall display devices are typically composed of multiple frames spliced ​​together, with the screen mounted on the frames to form an overall display structure. Traditional screen installation methods often use bolts or clips for fixing, requiring each screen to be aligned and secured during installation, and each screen to be loosened during disassembly. This process is cumbersome, especially when a particular screen needs to be maintained or replaced individually, often requiring the removal of surrounding screens or frames, resulting in low installation and disassembly efficiency.

[0004] When an exhibition hall display device is composed of multiple frames, the screens are tightly connected, making it difficult to disassemble a single screen using traditional fixing methods. Maintenance requires complete or large-area disassembly, which not only increases the difficulty of operation but also easily damages other screens or frames, affecting the stability and reliability of the display device. Therefore, a multi-section, expandable exhibition hall display device is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-section expandable exhibition hall display device, which aims to solve the problems in the prior art where it is difficult to independently disassemble and maintain a single screen, and the need for overall or large-area disassembly leads to cumbersome operation, low maintenance efficiency, and easy damage to surrounding components.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-section expandable exhibition hall display device, including a frame, a back plate in contact with the inner side of the frame, movable slots respectively opened on both sides of the back plate, a screen fixedly connected to the front of the back plate, a handle fixedly connected to the back of the back plate, a limit slot opened on the inner side of the handle, and a positioning component and a quick-release component respectively provided between the back plate and the frame.

[0007] The quick-release component includes a pressing plate. A towing rope is fixedly connected to the front surface of the pressing plate. The end of the towing rope movably penetrates through the back surface of the back plate and extends to the inner wall of the movable slot. An insertion block is fixedly connected to the end of the towing rope. The insertion block is located on the inner wall of the movable slot. The insertion block is elastically connected to the inner wall of the movable slot through spring A. Limit blocks are respectively fixedly connected to both sides of the pressing plate. The limit blocks are adapted to the limit slots. The limit blocks are elastically connected to the inner wall of the limit slots through spring B. Insertion slots are respectively formed on the inner walls of both sides of the frame. The outer side of the insertion block is inserted into the inner wall of the insertion slot.

[0008] As a further description of the above technical solution: The positioning component includes four dovetail sliders, with two as a group. The two groups of dovetail sliders are respectively fixedly connected to both sides of the back plate. A dovetail groove is formed on the front surface of the frame. The number of the formed dovetail grooves is the same as that of the dovetail sliders. The outer wall of the dovetail slider is slidably connected to the inner wall of the dovetail groove.

[0009] As a further description of the above technical solution: Sliders are respectively fixedly connected to the top and bottom of the insertion block. A sliding groove is formed on the inner wall of the movable slot. The insertion block is slidably connected to the inner wall of the sliding groove through the slider.

[0010] As a further description of the above technical solution: One end of spring A is fixedly connected to the inner wall of the movable slot, and the other end of spring A is fixedly connected to the side surface of the insertion block.

[0012] As a further description of the above technical solution: The pressing plate is in a "C" shape.

[0013] As a further description of the above technical solution: A fixed pulley is fixedly connected to the inner wall of the back plate. The surface of the towing rope contacts the surface of the fixed pulley.

[0014] As a further description of the above technical solution: Extension plates are respectively fixedly connected to the four peripheries of the outer side of the frame. Threaded holes are formed on the surfaces of the extension plates. Bolts are threadedly connected to the formed threaded holes of the extension plates.

[0015] As a further description of the above technical solution: Both the limit slot and the limit block are in a "T" shape. Both sides of the pressing plate are slidably connected to the inner wall of the limit slot through the limit blocks.

[0016] As a further description of the above technical solution: The number of the formed dovetail grooves is the same as that of the dovetail sliders.

[0017] This utility model has the following beneficial effects:

A limiting groove 12 is provided on the inner side of the handle 6. Extension plates 5 are fixedly connected to the outer perimeter of the frame 1. The extension plates 5 are used to connect multiple frames 1, so that multiple frames 1 can form a larger display frame structure to meet the display needs of different sizes of exhibition halls. Threaded holes are provided on the surface of the extension plates 5. The threaded holes are used to cooperate with bolts 3 to realize the connection of the frame 1 with other frames 1. Bolts 3 are connected to the threaded holes of the extension plates 5. The bolts 3 are used to firmly connect multiple frames 1 together by cooperating with the threaded holes. Positioning components and quick-release components are respectively provided between the back plate 4 and the frame 1.

[0031] Reference Figure 4 , Figure 5, the quick-release component includes a pressing plate 10. The pressing plate 10 is in a "U" shape and is used for an operator to apply force to press, so as to drive the traction rope 18 to pull the insertion block 8 to move. The front surface of the pressing plate 10 is fixedly connected with the traction rope 18. The traction rope 18 is used to transmit the pulling force of the pressing plate 10 and drive the insertion block 8 to move. The end of the traction rope 18 movably penetrates through the back surface of the back plate 4 and extends to the inner wall of the movable groove. The end of the traction rope 18 is fixedly connected with an insertion block 8. The insertion block 8 is used to insert into the slot 16 of the frame 1 to realize the fixation of the back plate 4 and the screen 2. A fixed pulley 11 is fixedly connected to the inner wall of the back plate 4. The fixed pulley 11 is used to change the direction of the pulling force of the traction rope 18, so that the traction rope 18 can pull the insertion blocks 8 on both sides of the back plate 4 to approach each other. The surface of the traction rope 18 contacts the surface of the fixed pulley 1,. The movable groove is used to accommodate components such as the insertion block 8 and the spring A7 and provide a moving space for them. The insertion block 8 is located on the inner wall of the movable groove. The insertion block 8 is elastically connected to the inner wall of the movable groove through the spring A7. The spring A7 provides a reset elastic force for the insertion block 8, so that it can automatically insert into the slot 16 to fix the back plate 4 and the screen 2. One end of the spring A7 is fixedly connected to the inner wall of the movable groove, and the other end of the spring A7 is fixedly connected to the side surface of the insertion block 8. Sliders 9 are fixedly connected to both the top and bottom of the insertion block 8. The sliders 9 cooperate with the sliding grooves on the inner wall of the movable groove to ensure the stable sliding of the insertion block 8 without deviation. The inner wall of the movable groove is provided with sliding grooves, and the insertion block 8 is slidably connected to the inner wall of the sliding groove through the limiting block 14.

[0032] Refer to Figure 5 , Figure 6 , limiting blocks 14 are respectively fixedly connected to both sides of the pressing plate 10. The limiting blocks 14 cooperate with the limiting grooves 12 to ensure the stability and guiding property of the sliding of the pressing plate 10. The limiting blocks 14 are adapted to the limiting grooves 12. Both the limiting grooves 12 and the limiting blocks 14 are in a "T" shape. Both sides of the pressing plate 10 are respectively slidably connected to the inner wall of the limiting groove 12 through the limiting blocks 14. The limiting blocks 14 are elastically connected to the inner wall of the limiting groove 12 through the spring B13. The spring B13 provides a reset elastic force for the pressing plate 10, so that the pressing plate 10 can automatically reset after being pressed. One end of the spring B13 is fixedly connected to the inner wall of the limiting groove 12, and the other end of the spring B13 is fixedly connected to the back surface of the limiting block 14. Slots 16 are respectively opened on both inner walls of the frame 1. The slots 16 cooperate with the insertion blocks 8 to ensure the stability of the screen 2 after installation. The outer side of the insertion block 8 is inserted into the inner wall of the slot 16.

[0033] Refer to Figure 3, the positioning component includes a dovetail slider 15, which is mutually adapted to the dovetail groove 17 for achieving the preliminary positioning and guiding of the back plate 4 and the screen 2. The number of dovetail sliders 15 is four, with every two as a group. The two groups of dovetail sliders 15 are respectively fixedly connected to both sides of the back plate 4. A dovetail groove 17 is formed on the front surface of the frame 1, which is used to cooperate with the dovetail slider 15 to achieve the sliding installation and positioning of the back plate 4 and the screen 2. The number of dovetail grooves 17 formed is the same as the number of dovetail sliders 15, and the outer wall of the dovetail slider 15 is slidably connected to the inner wall of the dovetail groove 17.

[0034] Working principle: Align the extension plates 5 of multiple frames 1, and the threaded holes on the extension plates 5 correspond to each other. The extension plate 5 of the frame 1 is the key connecting part, and the threaded holes are used to cooperate with the bolts 3 to achieve the connection between the frames 1.

[0035] Pass the bolt 3 through the threaded hole and gradually tighten it to firmly connect each frame 1 together. The bolt 3 meets the display requirements of exhibition halls of different scales through the cooperation with the threaded hole. After the frame 1 is installed, the screens 2 contact each other, and the back plate 4 is located inside the frame 1 to improve the display effect.

[0036] Installation steps of the screen 2: Align the dovetail slider 15 on the back plate 4 with the dovetail groove 17 on the front surface of the frame 1. The dovetail slider 15 is mutually adapted to the dovetail groove 17 for achieving the preliminary positioning and guiding of the back plate 4 and the screen 2. Push the back plate 4 to make the dovetail slider 15 slide along the dovetail groove 17 until the back plate 4 fits the frame 1. At this time, the back plate 4 is located inside the frame 1, the screen 2 is located on the front surface of the frame 1 and the screens 2 contact each other. During the installation process of the back plate 4, the insertion block 8 automatically inserts into the slot 16 on the inner walls of both sides of the frame 1 under the action of the spring A7. The spring A7 provides a reset elastic force for the insertion block 8 to enable it to automatically fix the back plate 4 and the screen 2. The cooperation between the insertion block 8 and the slot 16 ensures the stability of the screen 2 after installation.

[0037] Disassembly steps of the screen 2: The operator grasps the handle 6 on the back surface of the back plate 4. The handle 6 facilitates the operator to apply force and is convenient for disassembly operations. Press the pressing plate 10 inside the handle 6. The pressing plate 10 is in a "匚" shape, and the limiting blocks 14 on both sides of it slide in the limiting groove 12 while squeezing the spring B13. The limiting block 14 cooperates with the limiting groove 12 to ensure the stability and guiding property of the sliding of the pressing plate 10. The spring B13 provides a reset elastic force for the pressing plate 10. The pressing plate 10 pulls the traction rope 18. One end of the traction rope 18 is connected to the pressing plate 10, and the other end is connected to the insertion block 8. Its surface contacts the fixed pulley 11 on the inner wall of the back plate 4. The fixed pulley 11 changes the pulling direction of the traction rope 18 to make the traction rope 18 pull the insertion blocks 8 on both sides of the back plate 4 to approach each other.

[0038] The insert 8 overcomes the elastic force of the spring A7 and moves into the inner side of the movable groove on both sides of the back plate 4 until the insert 8 separates from the slots 16 on both sides of the frame 1. The movable groove is used to accommodate the insert 8, spring A7 and other components, providing them with space to move. The sliders 9 at the top and bottom of the insert 8 cooperate with the sliding grooves on the inner wall of the movable groove to ensure that the insert 8 slides stably and does not deviate.

[0039] Push the handle 6 to move the back panel 4 and screen 2 forward. The dovetail slider 15 on the back panel 4 slides along the dovetail groove 17 of the frame 1 until the dovetail slider 15 separates from the dovetail groove 17, at which point the screen 2 can be removed.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
