Technical Field

[0001] The present application relates to the technical field of light box billboards, and in particular to a light box billboard that is convenient for replacing advertising cloth. Background Art

[0002] A billboard is a signaling tool used in a pull system to initiate the next production step or to move work-in-progress to a downstream process. The term "signal" means "signal board" or "signal board" in Japanese. It generally refers to any outdoor media used to convey advertising messages. The size of the media varies depending on the specific environment.

[0003] However, in actual applications, most existing light box billboards are usually installed at a higher height when in use in order to increase the display range. However, when replacing the advertising cloth, high-altitude operations make it inconvenient to replace the advertising cloth, resulting in limitations. At the same time, high-altitude operations also lead to certain risks, which is not conducive to promotion and use.

[0004] Therefore, those skilled in the art provide a light box billboard that is convenient for replacing advertising cloth to solve the problems raised in the above background technology. Utility Model Content

[0018] The following will be combined with the Figure 1-3 The technical solution of the present invention is clearly and completely described. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0019] The embodiment of the present application discloses a light box billboard that is convenient for replacing advertising cloth, referring to Figure 1-3 The top side of the mounting base 1 is fixedly connected with a column 2, a cavity is opened inside the column 2, and vertical holes are opened on the front and rear sides of the column 2. A transmission block 3 is slidably sleeved on the outer side of the column 2, and the transmission block 3 is slidably connected to the inner walls of the two vertical holes. The bottom side wall of the cavity is fixedly connected with a motor 4, and the output shaft of the motor 4 is fixedly connected with a screw rod 5. The screw rod 5 is spirally connected to the transmission block 3, and the right side of the transmission block 3 is fixedly connected with an advertising box 6; by setting the transmission block 3, the output shaft of the motor 4 drives the screw rod 5 to rotate, the screw rod 5 drives the transmission block 3 to move downward, and the transmission block 3 drives the advertising box 6 to move downward, thereby lowering the height of the advertising box 6, so that workers can replace the advertising cloth. At the same time, the adjustability of the advertising box 6 can be conveniently applied to workers of different heights, thereby effectively improving the convenience of operation and avoiding the occurrence of danger.

[0020] In the present application, a first fixing frame 7 is fixedly connected to the inner wall of the rear side of the advertising box 6, and a second fixing frame 8 is slidably connected to the inner wall of the rear side of the advertising box 6. A screw rod 9 is rotatably connected to the center of the right side of the advertising box 6, and the screw rod 9 is spirally connected to the second fixing frame 8. The front sides of the first fixing frame 7 and the second fixing frame 8 are clamped with the two cloth shafts of the external advertising cloth; by setting the screw rod 9, when the advertising cloth is replaced, the screw rod 9 is twisted, and when the screw rod 9 rotates, it drives the second fixing frame 8 to gradually move closer to the first fixing frame 7, so that the advertising cloth can be easily removed, avoiding the inconvenience of disassembly due to the long distance between the two ends of the advertising cloth.

[0021] In this application, a support wheel 12 is installed on the left side of the advertising box 6, and the support wheel 12 is in contact with the right side of the column 2; by setting the support wheel 12, when the advertising box 6 moves downward, the center of gravity of the entire advertising box 6 shifts to the right. At this time, the support wheel 12 can prevent the connection between the transmission block 3 and the advertising box 6 from being deformed, thereby providing a certain degree of protection for the advertising box 6.

[0022] In the present application, two guide rods 10 are fixedly connected to the right inner wall of the advertising box 6, and both guide rods 10 are slidably connected to the second fixed frame 8; by setting the guide rods 10, when the second fixed frame 8 slides left or right, the two guide rods 10 cooperate with each other to enable the second fixed frame 8 to maintain horizontal movement to avoid deviation.

[0023] In this application, four angled support frames 11 are fixedly connected to the top side of the mounting base 1, and the four angled support frames 11 are respectively fixedly connected to the four sides of the column 2; by setting the angled support frames 11, the four angled support frames 11 cooperate with each other to reinforce and support the column 2 from four sides, thereby improving the overall stability.

[0024] The standard parts used in this utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0025] The implementation principle of the light box billboard for facilitating the replacement of advertising cloth in the embodiment of the present application is as follows: when in use, the output shaft of the motor 4 drives the screw rod 5 to rotate, the screw rod 5 drives the transmission block 3 to move downward, and the transmission block 3 drives the advertising box 6 to move downward, thereby lowering the height of the advertising box 6 to facilitate workers to replace the advertising cloth. At the same time, the adjustability of the advertising box 6 can be conveniently adapted to workers of different heights, thereby effectively improving the convenience of operation and avoiding the occurrence of danger. When replacing the advertising cloth, the screw rod 9 is twisted, and when the screw rod 9 rotates, it drives the second fixing frame 8 to gradually move closer to the first fixing frame 7. This makes it easy to remove the advertising cloth and avoids the inconvenience of disassembly caused by the long distance between the two ends of the advertising cloth. When the advertising box 6 moves downward, the center of gravity of the entire advertising box 6 shifts to the right. At this time, the support wheel 12 can prevent the connection between the transmission block 3 and the advertising box 6 from deformation, thereby providing a certain protection for the advertising box 6. When the second fixing frame 8 slides left or right, the two guide rods 10 cooperate with each other to keep the second fixing frame 8 moving horizontally to avoid deviation. The four angled support frames 11 cooperate with each other to reinforce and support the column 2 from four sides, thereby improving the overall stability.

[0026] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection. "Up," "down," "left," and "right" are only used to indicate relative positional relationships. When the absolute positions of the objects being described change, the relative positional relationships may also change.

[0027] Secondly: The drawings of the disclosed embodiments of the present invention only involve structures related to the disclosed embodiments. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of the present invention can be combined with each other.
