Description

Technical Field

[0001] This utility model relates to the field of light box technology, and in particular to a light box with a stable support structure. Background Technology

[0002] The main components of a lightbox include the outer shell, internal structure, light source, reflective film and diffusion film, and control panel. These components work together to provide a stable, uniform, and soft lighting effect to meet the needs of various scenarios. Some lightboxes have lightbox cloth inside, also known as advertising cloth, which can be used as an advertising lightbox.

[0003] Existing light boxes using light box fabric typically employ a clamping method to tighten the fabric. However, the clamped fabric is prone to damage after prolonged use, affecting its tension and causing some adverse effects on users. To address the shortcomings of existing technologies, we propose a light box with a stable support structure. Utility Model Content

[0004] The main purpose of this utility model is to provide a lightbox with a stable support structure, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A lightbox with a stable support structure includes a lightbox body, a base rotatably connected to the bottom of the lightbox body, a limit frame detachably installed on the top of the lightbox body, a through hole on one side of the top of the limit frame, a cover plate slidably connected to the outside of the limit frame, an elastic rubber column fixedly connected to the bottom of the inner wall of the through hole of the limit frame, a connecting column fixedly connected to the top of the elastic rubber column, a fixed column rotatably connected to the top of the connecting column, a first octagonal column detachably installed on the bottom of the inner wall of the lightbox body, a second octagonal column movably sleeved on the outer side of one end of the first octagonal column, four sets of movable sleeves evenly rotatably connected to the outer circumference of the second octagonal column, an adjusting screw threadedly connected to one end of each movable sleeve, a fixed frame detachably installed on one end of the adjusting screw, and a rotating rod rotatably connected inside the fixed frame.

[0007] Preferably, the top of the light box body abuts against the bottom of the cover plate, and one side of the bottom of the cover plate is connected through to one end of the fixing column.

[0008] Preferably, the inner wall of the light box body is slidably connected to the outer side of the fixing frame, and the height of the fixing frame is the same as the height of the inner wall of the light box body.

[0009] Preferably, four sets of grooves are evenly formed around the outer side of the second octagonal column, and a lamp tube can be detachably installed inside the grooves formed in the second octagonal column.

[0010] Preferably, one end of the adjusting screw passes through one side of the second octagonal column, and the bottom of the second octagonal column abuts against the bottom of the inner wall of the light box body.

[0011] Preferably, the inside of the through hole in the limiting frame is slidably connected to the outside of the connecting post, and the inside of the through hole in the limiting frame is inserted into the outside of one end of the fixing post.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this utility model, the adjustable screw moves on the movable sleeve to drive the fixed frame to drive the rotating rod to support the fabric of the light box. The degree of support is adjustable, no additional clamping structure is required, which reduces damage to the fabric of the light box. It can effectively support the fabric of the light box, and the overall surface is flat and more beautiful.

[0014] 2. In this utility model, after the cover plate is pulled up to lift the fixing column and the connecting column, the cover plate is rotated to open on the light box body. Then, the fixing frame is moved towards the second octagonal column and the second octagonal column is pulled to drive the limiting frame to detach from the light box body. The light box cloth attached to the rotating rod can be easily disassembled and assembled, and the operating space is larger, making it more convenient for staff to operate.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figures 1-4As shown, a lightbox with a stable support structure rotates by turning the movable sleeve 10 on the second octagonal column 9. The rotating movable sleeve 10 drives the adjusting screw 11 to move on the movable sleeve 10 via a thread. The adjusting screw 11 drives the fixed frame 12 to move and the rotating rod 13 to move, adjusting the distance between the fixed frame 12 and the second octagonal column 9. Thus, the adjusting screws 11 on the four sets of movable sleeves 10 around the outer side of the second octagonal column 9 all drive the fixed frame 12 to drive the rotating rod 13. The four sets of rotating rods 13 work together to support the lightbox cloth inside the lightbox body 1. Then, the lamp tube 14 is turned on to illuminate the lightbox cloth inside the lightbox body 1. The adjusting screw 11, in conjunction with the fixed frame 12 and the rotating rod 13, supports the lightbox cloth more evenly inside the lightbox body 1.

[0022] When the adjusting screw 11 moves on the movable sleeve 10 to drive the fixed frame 12 and the rotating rod 13 to support the light box fabric, the rotating rod 13 rotates on the fixed frame 12 when the light box fabric is supported, preventing excessive friction between the rotating rod 13 and the light box fabric from damaging the light box fabric. When the fixed frame 12 is pushed by the adjusting screw 11 inside the light box body 1, the height of the fixed frame 12 is the same as the height of the inner wall of the light box body 1. The light box body 1 restricts the movement of the fixed frame 12 inside the light box body 1, so that the fixed frame 12 stably drives the rotating rod 13 to move inside the light box body 1 to support the light box fabric.

[0023] Example 2, as Figures 2-4 As shown, a lightbox with a stable support structure is opened by pulling the cover plate 4. The cover plate 4 drives the fixed column 7 and the connecting column 6 to stretch the elastic rubber column 5 until the connecting column 6 and the fixed column 7 are separated from the through hole opened by the limiting frame 3. Then, pulling the cover plate 4 drives the fixed column 7 to rotate on the connecting column 6, thereby opening the cover plate 4 on the lightbox body 1. Then, by loosening the movable sleeve 10, the adjusting screw 11 is moved into the second octagonal column 9. The adjusting screw 11 drives the fixed frame 12 and the rotating rod 13 to move towards the second octagonal column 9 until the top of the fixed frame 12 is no longer restricted by the inner wall of the lightbox body 1. This pulls the second octagonal column 9, causing the movable sleeve 10, the adjusting screw 11, the fixed frame 12 and the rotating rod 13 to move upward and separate from the lightbox body 1. The second octagonal column 9 is then removed from the lightbox body 1, completing the removal of the second octagonal column 9, the movable sleeve 10, the adjusting screw 11, the fixed frame 12 and the rotating rod 13.

[0024] It should be noted that this utility model is a light box with a stable support structure. In use, the cover plate 4 is moved upward to pull the fixed column 7, which in turn drives the connecting column 6 to stretch the elastic rubber column 5. Then, the cover plate 4 is rotated to drive the fixed column 7 to rotate on the connecting column 6. Then, the movable sleeve 10 is turned to drive the adjusting screw 11 to drive the fixed frame 12 to drive the rotating rod 13 to retract towards the second octagonal column 9 and pull the second octagonal column 9 away from the light box body 1, thereby removing the second octagonal column 9, movable sleeve 10, adjusting screw 11, fixed frame 12 and rotating rod 13, making it convenient to disassemble and assemble the light box cloth on the outside of the rotating rod 13.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
