Technical Field

[0001] This utility model relates to the field of bookshelf technology, and in particular to a rotating bookshelf for use in public utility management offices. Background Technology

[0002] Public service management venues (such as government service centers, community service stations, and libraries) are important locations providing administrative services, information consultation, and cultural dissemination to the public, characterized by high foot traffic and diverse service needs. Installing bookshelves in these venues provides convenient reading resources for the public, such as policies and regulations, service guides, and popular science books, optimizing the service experience and improving space utilization. Rotating bookshelves, in particular, are widely used due to their efficient use of corner space and the engaging dynamic access options.

[0003] Currently, most rotating bookshelves used in public areas employ welding or bolting to fix the shelves, resulting in no adjustable shelf spacing. This design makes it difficult to accommodate books of different sizes, leaving large books unsuitable for storage. Therefore, this application proposes a rotating bookshelf for use in public utility management offices to solve the aforementioned problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-12 This utility model provides a technical solution: a rotating bookshelf for use in public utility management offices, including a bottom support frame 1, a moving wheel 2 at the lower end of the bottom support frame 1, a support column 3 fixedly connected to the upper end of the bottom support frame 1, an adjusting cylinder 11 fixedly connected to the upper end of the support column 3, a bottom fixing plate 9 and several adjusting support plates 10 above the bottom support frame 1, the upper end of the support column 3 passing through the bottom fixing plate 9 and fixedly connected to the bottom fixing plate 9, a through hole 23 on the adjusting support plate 10, the upper end of the adjusting cylinder 11 passing through several through holes 23 in sequence and fixedly connected to a top plate 15, an adjusting mechanism is provided inside the adjusting cylinder 11, a protective cylinder 17 is fixedly connected to the upper end of both the bottom fixing plate 9 and the adjusting support plate 10, the protective cylinder 17 is coaxially arranged with the adjusting cylinder 11, and four limiting frames 18 are fixedly connected to the outer wall of the protective cylinder 17, the limiting frames 18 are L-shaped and the four limiting frames 18 are arranged in a circular array;

[0030] The adjustment mechanism includes a rotating rod 13, the lower end of which is rotatably connected to the upper end of the support column 3. The upper end of the rotating rod 13 passes through the upper side wall of the adjustment cylinder 11 and the top plate 15 in sequence and is fixedly connected to an adjustment rotating plate 14. Two limiting slides 12 are opened on the side wall of the adjustment cylinder 11. Several adjustment plates 21 are provided inside the adjustment cylinder 11. Several adjustment threads 16 are opened on the rotating rod 13. Several adjustment plates 21 are threadedly connected to several adjustment threads 16 respectively. The pitch of several adjustment threads 16 gradually increases from bottom to top. The gradual pitch adjustment threads 16 are linked with the adjustment plates 21. By rotating the adjustment rotating plate 14, all adjustment support plates 10 can be moved in position synchronously, thereby realizing the height adjustment of several adjustment support plates 10, thereby improving the adaptability of the device and meeting the placement needs of some large books.

[0031] A rotating ring 20 is sleeved on the outer side of the adjusting cylinder 11. The left and right ends of the adjusting plate 21 pass through two limiting slides 12 and are fixedly connected to the inner sidewall of the rotating ring 20. A connecting frame 19 is rotatably connected to the outer side of the rotating ring 20. The outer sidewall of the connecting frame 19 is fixedly connected to the inner sidewall of the protective cylinder 17. Several adjusting support plates 10 can rotate independently, so that the device can meet the needs of multiple people to select books at the same time in different layers without causing interference.

[0032] The lower ends of the adjustable support plate 10, the bottom fixing plate 9 and the top plate 15 are all equipped with lighting lamps 22, equipment power supply 24 and lighting switches 25. The lighting lamps 22 are ring-shaped. The lighting lamps 22 enable the device to provide lighting for readers in dim environments, making it easier to find books.

[0033] A support frame 5 is provided above the bottom support frame 1, and a sliding frame 4 is fitted on the support column 3. The lower end of the sliding frame 4 passes through the upper side wall of the support frame 5 and is fixedly connected to the support frame 5. Two internal thread limiting grooves 8 are opened on the right side wall of the support column 3. A limiting bolt 7 is provided on the outer side of the sliding frame 4. The left end of the limiting bolt 7 passes through the right side wall of the sliding frame 4 and is threadedly connected to the internal thread limiting groove 8. When the device moves, the limiting bolt 7 passes through the side wall of the sliding frame 4 and cooperates with the internal thread limiting groove 8 on the upper side. At this time, the lower end of the support frame 5 does not contact the ground, and the moving wheel 2 facilitates the overall position movement of the device.

[0034] The lower end of the support frame 5 is fixedly connected to a contact rubber pad 6. After the bookshelf is moved to the designated position, the limiting bolt 7 passes through the side wall of the sliding frame 4 and cooperates with the internal thread limiting groove 8 at the lower position. The lower end of the contact rubber pad 6 contacts the ground, thereby using the support frame 5 to provide good support for the bookshelf and better prevent the bookshelf from tipping over. At the same time, the setting of the contact rubber pad 6 effectively prevents the device from scratching the ground.

[0035] Working principle: When the device moves, the limiting bolt 7 passes through the side wall of the sliding frame 4 and engages with the internal thread limiting groove 8 on the upper side. At this time, the lower end of the support frame 5 does not contact the ground, and the moving wheel 2 facilitates the overall movement of the device. After the bookshelf is fixed in position, the limiting bolt 7 passes through the side wall of the sliding frame 4 and engages with the internal thread limiting groove 8 on the lower side, so that the lower end of the contact rubber pad 6 contacts the ground. In this way, the support frame 5 provides good support for the bookshelf and can better prevent the bookshelf from tipping over. The device utilizes the combination of the limiting frame 18 and the protective cylinder 17 to provide a placement area for books. An adjustment mechanism is installed inside the adjustment cylinder 11, employing a gradually increasing pitch adjustment thread 16 linked to the adjustment plate 21. By rotating the adjustment plate 14, all adjustment support plates 10 can be moved synchronously, thereby achieving height adjustment of several adjustment support plates 10, thus improving the adaptability of the device and meeting the placement needs of some large-sized books. Several adjustment support plates 10 in the device can rotate independently, allowing the device to meet the needs of multiple people simultaneously selecting books at different levels without causing interference. The lighting 22 provides illumination for readers in dimly lit environments, facilitating book searching.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
