Description

Technical Field

[0001] This application relates to the technical field of billboards, and in particular to an adjustable billboard. Background Technology

[0002] Advertising, in essence, means to inform widely. It is a means of publicity that uses certain media to publicly and extensively convey information to the public for a specific purpose. A billboard is a signaling tool in a pull system, used to initiate the next production process or move work-in-process to the downstream process. The term "advertising" in Japanese means "signal" or "signal board," and broadly refers to all outdoor media that convey advertising information.

[0003] In existing technologies, most billboards have a fixed structure and cannot be height-adjusted. Furthermore, because they are placed outdoors, children playing with them can easily rotate the control rods, affecting the adjusted height and thus the billboard's visual appeal. Therefore, to solve these problems, this application provides an adjustable billboard. Utility Model Content

[0004] To address the issues of difficulty in height adjustment and the ease with which children can rotate the boom, this application provides an adjustable billboard.

[0005] This application provides an adjustable billboard, including a base. A support column is fixedly connected to the center of the upper surface of the base. A lifting groove is formed on one side of the inner side of the support column. A threaded rod is rotatably connected to one side of the inner side of the lifting groove, and the threaded rod extends into the interior of the base. A lifting plate is threadedly connected to one side of the outer wall of the threaded rod. A limit plate is fixedly connected to one side of the lifting plate. Telescopic rods are fixedly connected to both sides of the upper surface of the base corresponding to the support column. The billboard body is lifted and lowered to the upper surface of the base through the support column and the two telescopic rods.

[0006] Preferably, a fixing rod is fixedly connected to one side of the base, a first bevel gear is rotatably connected to one side of the fixing rod, and a second bevel gear is fixedly connected to one side of the threaded rod, with the first bevel gear and the second bevel gear meshing tightly.

[0007] Preferably, slots are provided on both sides of the side surface of the first bevel gear, and a pull rod is slidably connected to the inside of the base through the fixing rod. A locking block is fixedly connected to the outer wall of the pull rod on the side corresponding to the slot.

[0008] Preferably, a groove is provided on one side of the inside of the fixed rod, and a connecting plate is fixedly connected to the inside of the pull rod corresponding to the side of the groove.

[0009] Preferably, the outer wall of the pull rod is sleeved with an elastic member corresponding to one side of the connecting plate, and the outer wall of the base is slidingly connected with a rotating rod through the pull rod.

[0010] To sum up, the present application has the following beneficial technical effects:

[0011] 1. By pulling the rotating rod to drive the clamping block to insert into the clamping groove, the first bevel gear is driven to rotate by rotating the rotating rod, the second bevel gear is driven to rotate by the close meshing between the first bevel gear and the second bevel gear, and the threaded rod is driven to rotate in the lifting groove, the lifting plate is lifted along the inner wall of the lifting groove by the rotation of the threaded rod, so that the height of the advertising board body is adjusted; compared with the prior art, the height of the advertising board can be adjusted conveniently.

[0012] 2. The size of the connecting plate is matched with the size of the sliding groove, the elastic member is located on one side of the connecting plate and is not connected, the elastic potential energy generated by the compression of the elastic member pushes the connecting plate to reset, and then the pull rod and the first bevel gear are separated; compared with the prior art, the height of the advertising board is not affected by the rotation of the rotating rod by children.
