Description

Technical Field

[0001] This utility model relates to the field of library technology, specifically to a book anti-tipping limiter for libraries. Background Technology

[0002] In libraries, bookstores, archives, and home studies, bookshelves serve as the core carrier for storing and displaying books. The stability and neatness of the books on the shelves directly affect space utilization, borrowing convenience, and the overall aesthetics of the environment. When limiting the movement of books, bookshelves typically place the limiting plate on one side of the shelf, creating a barrier only at the end of the book arrangement (limiting lateral movement of books and preventing them from tipping over when the shelf is not full). However, when a single book is removed from the middle (especially in the area of ​​thick-spined social science books), the books on both sides lose their inner support, which can easily cause the entire row of books to tilt towards the side from which the book is being removed. To address this issue, the inventor has proposed a library book anti-tipping limiter. Utility Model Content

[0003] To address the problem that when a single book is removed from the middle, the books on either side lose their inner support, this utility model aims to provide a library book anti-tipping limiter.

Clamping plates 32 are slidably connected between the outer rings of the two vertical shafts 33. A rack 4 is fixedly connected to the center of the top of the mounting base 1, and guard plates 41 are symmetrically fixedly connected to the top of the mounting base 1 near the rack 4. A sliding seat 2 is slidably connected between the two guard plates 41. A connecting plate 44 is fixedly connected between the inner walls. A positioning shaft 43 is slidably inserted inside the connecting plate 44. A limiting plate 45 is fixedly connected to the outer ring of the positioning shaft 43 near the top. A spring 46 is fixedly connected to the top of the limiting plate 45 and sleeved on the outer ring of the positioning shaft 43. The other end of the spring 46 is fixedly connected to the connecting plate 44. A U-shaped seat 22 is slidably inserted at the top of the slide block 2. A blocking plate 26 is rotatably connected between the inner walls of the U-shaped seat 22. In its natural state, the spring 46 is in a slightly compressed state, providing a downward preload for the positioning shaft 43.

[0017] A square plate 23 is fixedly connected to the outer end of the U-shaped seat 22 near the bottom, and a screw 25 is rotatably connected to the bottom end of the square plate 23 near the center of one side.

[0018] By adopting the above technical solution, the screw 25 is a trapezoidal threaded screw, and a rotating handle is fixedly installed at the top of the square plate 23 for easy operation and rotation.

[0019] The outer end of the slide block 2 is fixedly connected to the top of the square plate 24, which is adapted to the square plate 23, and the square plate 24 is threadedly connected to the screw 25.

[0020] By adopting the above technical solution, a limit ring is set at the bottom of the screw 25 to position the maximum lifting height of the U-shaped seat 22.

[0021] The mounting base 1 has several positioning holes 42 at the top center that are adapted to the positioning shaft 43, and the positioning holes 42 and the positioning shaft 43 are on the same horizontal plane.

[0022] By adopting the above technical solution, the positioning hole 42 and the positioning shaft 43 are on the same vertical plane, ensuring that the positioning shaft 43 can be accurately inserted.

[0023] A gear 21 is rotatably connected to the side wall of the slide 2 near the bottom, and the gear 21 meshes with the rack 4.

[0024] By adopting the above technical solution, the gear 21 that meshes with the rack 4 is provided to facilitate the horizontal movement of the auxiliary slide 2.

[0025] The outer ring of the limit plate 45 is fixedly connected to a U-shaped actuating shaft.

[0026] The U-shaped actuating shaft is designed to facilitate the up-and-down movement of the limit plate 45 by adopting the above technical solution.

[0027] A screw 31 is rotatably connected to the bottom end of the base plate 3 near the center of one side, and the clamping plate 32 is rotatably connected to the screw 31 by a thread.

[0028] By adopting the above technical solution, a limiting disc is provided at the bottom of the vertical shaft 33 to limit the height of the lifting and lowering of the clamping plate 32.

[0029] Working principle: When using this device, firstly, by rotating the two screws 31, the threaded clamping plate 32 is lowered. Then, the clamping plate 32 and the base plate 3 are inserted between the two screws 31 and the front end of the bookshelf. Then, the two screws 31 are rotated in the opposite direction. At this time, the clamping plate 32, which is threadedly connected to it, will move upward and work with the base plate 3 to complete the clamping work of the bookshelf (rubber pads are symmetrically arranged at opposite ends of the clamping plate 32 and the base plate 3 to improve the stability of the clamping). This allows the device to be quickly installed on the bookshelf board. In use, by lifting the limiting plate 45 upwards, the fixedly connected positioning shaft 43 is raised (compressing the spring 46), thereby moving the positioning shaft 43 out of the positioning hole 42. Then, under the action of the gear 21 and the rack 4, the slide 2 is driven to move horizontally, making it easier to move the blocking plate 26 to the desired position (book retrieval position). Then, the force on the limiting plate 45 is released, allowing the positioning shaft 43 to be inserted into the positioning hole 42 to complete the positioning effect of the slide 2. Next, rotating the screw 25 can adjust the height of the U-shaped seat 22 and the blocking plate 26. Finally, flipping the blocking plate 26 can rotate it to the empty book position, thereby achieving the effect of supporting the books on both sides and preventing the books on both sides of the empty slot (book retrieval position) from tilting towards each other.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
