[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0019] like Figure 1 and Figure 2As shown, a rotatable sign includes: a sign body 1 and a fixed surrounding frame 2. The fixed surrounding frame 2 is disposed around the outer periphery of the sign body 1, leaving space between the sign body 1 and the sign body 1 for rotation. Preferably, the sign body 1 is a rectangular parallelepiped structure with rounded corners. The fixed surrounding frame 2 is adapted to the rectangular structure of the sign body 1, also having a rounded corner, to give the sign a unified and aesthetically pleasing appearance.

[0020] like Figure 2 and Figure 3 As shown, a rotating shaft 3 is provided along the centerline of the sign body 1, which is the centerline along the length direction of the sign body 1. The first end of the rotating shaft 3 is rotatably connected to the fixed surrounding frame 2, and the second end passes through the fixed surrounding frame 2 and extends into a transmission box 4 fixedly provided on the fixed surrounding frame 2.

[0021] like Figure 4 As shown, a worm gear 5 is sleeved on the second end of the rotating shaft 3. The worm gear 5 is disposed in a transmission case 4 and meshes with a worm 6 also disposed in the transmission case 4. A shaft 7 is inserted into the center of the worm 6. One end of the shaft 7 extends to the outside of the transmission case 4. A winding disc 8 is provided on the section of the shaft 7 disposed outside the transmission case 4.

[0022] like Figures 1 to 3 As shown, a drawstring 9 is wound around the drum 8, with both ends of the drawstring 9 extending downward below the drum 8. Pulling the ends of the drawstring 9 can cause the drum 8 to rotate in different directions. Preferably, the ends of the drawstring 9 are connected together, and a counterweight 10 is mounted on the drawstring 9, which can slide along the drawstring 9. The counterweight 10 keeps the drooping portion of the drawstring 9 upright, reducing any swaying of the drawstring 9 caused by external factors.

[0023] A connecting plate 11 is provided at one end of the fixed surrounding frame 2; a connecting hole 12 is provided on the connecting plate 11. The sign can be fixedly connected to the wall through the connecting plate 11 and the connecting hole 12.

[0024] When in use, by pulling the pull rope 9 to one side, the winding disc 8 is driven to rotate, the winding disc 8 drives the worm 6 to rotate through the shaft 7, the worm 6 drives the worm wheel 5 to rotate, and the worm wheel 5 drives the sign body 1 to rotate through the rotating shaft 3, thereby realizing the rotation and flipping of the sign.

[0025] The signboard at a high position can be turned over at a low position by the hanging pull rope 9. Compared with the rotating signboard of the electric mechanical mechanism, the structure is simpler, the production cost is lower, and the applicability is wider.

[0026] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.

[0027] Finally, it should also be understood that certain technical features in the embodiments may not be necessary for solving specific technical problems, and thus these technical features may be absent or omitted without affecting the solution of the technical problem or the formation of a technical solution; moreover, the features, elements and / or functions of one embodiment may be appropriately combined, coupled or coordinated with the features, elements and / or functions of one or more other embodiments, unless the combination, coupling or coordination is obviously not feasible.
