Description

Technical Field

[0001] This utility model relates to the field of signage technology, specifically a large sign that is easy to replace. Background Technology

[0002] In the process of modern urbanization, large signage serves as an important information transmission tool, widely used in various fields such as commercial advertising and public information display. With the diversification of market demands and increasing efficiency requirements, how to achieve rapid replacement and maintenance of large signage has become a significant challenge for the industry.

[0003] Traditionally, the installation and replacement of large signs have relied on manual labor, which is not only time-consuming and labor-intensive, but also poses safety hazards, especially in high or hard-to-reach locations. Furthermore, the lack of effective mechanical assistance makes the dismantling of old signs and the installation of new ones complex and prone to damage, impacting work efficiency and cost control. This is particularly problematic in scenarios requiring frequent content updates, such as shopping mall promotions and exhibitions, where traditional methods are clearly insufficient to meet the demands of rapid market response. Therefore, this paper proposes a new type of large sign that is easy to replace. Utility Model Content

The output end of the drive motor is connected to a drive sprocket via a reducer. The drive sprocket and the transmission sprocket are connected by a transmission chain. The sign frame is also equipped with a tension wheel. The movable frame has a mounting slot on one side, and an electric telescopic rod is fixedly installed on one side of the movable frame. The output end of the electric telescopic rod is connected to a clamping plate. By setting a lead screw, transmission sprocket, drive motor, and drive sprocket inside the sign frame, the drive motor can drive the lead screw to rotate during use, thereby moving the movable frame. When in use, one end of the sign is inserted into the mounting slot, and the sign can be pushed out of the sign frame by pushing the movable frame, making it convenient and effortless to remove the sign. The sign is also clamped in the mounting slot and clamped by the clamping plate, which also makes it convenient to pull the sign into the sign frame when installing the sign. The above structure facilitates the replacement of the sign and improves the practicality of the device.

[0006] Preferably, auxiliary rollers are installed on both the upper and lower sides of the movable frame, and there are multiple auxiliary rollers.

[0007] Preferably, a conductive track is fixedly installed inside the sign frame, and a conductive block is fixedly connected to one side of the movable frame. The conductive block is slidably installed inside the conductive track.

[0008] Preferably, the conductive block is electrically connected to the electric telescopic rod.

[0009] Preferably, a cover plate is provided on one side of the sign frame, and a limiting bolt is inserted inside the cover plate.

[0010] Preferably, a threaded hole is provided on one side of the sign frame, and the limiting bolt is threaded into the inside of the threaded hole.
