Description

Technical Field

[0001] This utility model relates to the field of library exhibitions, specifically a rotating exhibition bookshelf for libraries. Background Technology

[0002] Library exhibition bookshelves are furniture designed specifically for libraries, bookstores, offices, and private studies. They aim to provide efficient and aesthetically pleasing solutions for book storage and display. Beyond storage, they also serve multiple functions such as display and categorization, making them an indispensable part of libraries. The "Rotating Portable Bookshelf for Libraries" disclosed in Chinese patent application number "201922020430.0" represents an increasingly mature technology. This utility model patent mentions that "by using ball bearing grooves, limiting plates, movable chambers, and movable balls, the edges of the chassis can be supported and limited when the chassis, rotating plate, and top plate rotate, thereby giving the chassis higher stability and flexibility during rotation, further reducing the risk of spin-induced rotational damage." The difficulty in rotating the bookshelf makes it more convenient to use. However, this exhibition bookshelf also has the following drawbacks: While the rotating bookshelf can indeed be controlled by the movable ball bearings in conjunction with the base and turntable, this structure makes it difficult to implement electromechanical control of the bookshelf's rotation, thus affecting its ease of use. Therefore, it is necessary to provide an exhibition bookshelf that can automatically control its rotation and improve its ease of use. In addition, while the bookshelf does achieve a dehumidification effect through its moisture absorption holes, the dehumidification effect achieved solely through the aforementioned structure is not significant enough. Therefore, it is necessary to provide an exhibition bookshelf that can improve dehumidification and drying effects and enhance its practicality. Utility Model Content

[0036] Please see Figure 2 - Figure 5 The base plate 103, the support plate 106, and the top plate 108 are all made of polyethylene plastic.

[0037] In one specific embodiment, the base plate 103, the receiving plate 106, and the top plate 108 made of polyethylene plastic can reduce their weight, thereby improving the ease of rotation and adjustment.

[0038] Working principle: In use, the servo motor 1052 in the transmission mechanism 105 is first started to drive the second bevel gear 1053 to rotate. The second bevel gear 1053 meshes with the first bevel gear 1051, which in turn drives the first bevel gear 1051 and the base plate 103 at its upper end to rotate. This, in turn, drives the first connecting shaft 104, the second connecting shaft 107, the supporting plate 106, and the top plate 108 to rotate. This allows for automatic adjustment of the rotation angle of the exhibition bookshelf, improving its ease of use. At the same time, the honeycomb holes 202 on the surface of the partitions 201 between the base plate 103, the supporting plate 106, and the top plate 108 provide ventilation. The desiccant packs 203 inside the partitions 201 further ensure that the inside of the exhibition bookshelf is dry, thus preventing the books from getting damp. Meanwhile, the lighting mechanism 109 provides illumination for the exhibition bookshelf, thereby enhancing its practicality.
