Description

Technical Field

[0001] This utility model relates to the field of library technology, specifically a high-position book retrieval auxiliary device for libraries. Background Technology

[0002] Because libraries have a large collection of books, and their bookshelves are usually quite high, librarians typically need to use ladders or footstools to access books on the upper shelves. This method has the following drawbacks: poor safety, as frequent climbing up and down ladders increases the risk of slips and falls, especially on slippery surfaces, when the ladder legs are not fully extended, or when the center of gravity is unstable due to moving books; and low efficiency, as retrieving a single book requires repeated movement and climbing of the ladder, making the process cumbersome and time-consuming. Furthermore, traditional ladders cannot assist in holding books, limiting the number of books librarians can retrieve at a time by hand, significantly increasing labor intensity and time costs.

[0003] CN216577826U discloses a library book retrieval aid device, including a fixed block. An L-shaped tube is fixedly connected to the right side wall of the fixed block, and a thicker cylinder is fixedly connected to the bottom of the L-shaped tube. A movable groove is formed on the left side wall of the fixed block, communicating with the interior of the L-shaped tube. A movable block is disposed within the movable groove. A blind hole is formed on the right side wall of the movable block, and a round tube is disposed within the blind hole. The right end of the round tube is fixedly connected to the right inner wall of the movable groove, and a pull rope is fixedly connected to the left inner wall of the blind hole. This utility model... The interaction between the pull rope and the clamping block allows the pull rope to move the moving block to the right, thus clamping the book. However, the pull rope is manually pulled by the staff to achieve clamping. This means that the staff needs to hold the entire device with one hand to maintain balance and pull the pull rope with the other hand to clamp the book. On the one hand, the strength of manual pulling is limited, and the book may slip due to insufficient clamping force. On the other hand, if the height is too high, it is difficult to hold the device steadily with one hand and it is difficult to accurately align the book, making it impossible to safely retrieve the book from a high position.

[0004] Based on this, a high-level book retrieval auxiliary device for libraries is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a high-position book retrieval auxiliary device for libraries to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A library high-position book retrieval auxiliary device includes a mounting base, and a clamping component is provided on the upper surface of the mounting base; The clamping assembly includes a clamping base, on one side of which a pair of clamping plates are slidably disposed. The two clamping plates are symmetrically arranged with one end located on the outside of the clamping base. A baffle is fixedly connected to the middle of each adjacent side of the two clamping plates. A motor is fixedly connected to one side of the clamping base. A threaded rod is disposed in the middle of the clamping base and driven by the motor. A slider is threaded to one end of the threaded rod. Several guide rods are symmetrically disposed at both ends of the slider. One end of each guide rod is rotatably connected to one side of the adjacent slider. Several rotating seats are disposed on the adjacent side of each of the two clamping plates and are rotatably connected to one end of the adjacent guide rod.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: a limit assembly is provided between the clamping plate and the clamping seat.

[0008] In one alternative: the limiting component includes a sliding groove, which is respectively opened on the upper and lower sides of the clamping seat. A sliding post is provided on the upper and lower sides of one end of each of the two clamping plates, and each sliding post is slidably connected to the inner side of the adjacent sliding groove.

[0009] In one alternative: both clamping plates are provided with a number of anti-slip strips on adjacent sides of the outer side of the clamping seat.

[0010] In one alternative: a battery compartment is provided on one side of the mounting base and a storage battery is installed inside.

[0011] In one alternative: the lower end of the mounting base is provided with an adjustment component.

[0012] In one alternative embodiment: the adjustment assembly includes a fixed tube, the upper end of which is fixedly connected to the lower end of the mounting base, a slide rod slidably connected to the lower end of the fixed tube, a handle fixedly connected to the lower end of the slide rod, an operation button provided on one side of the handle, a spring provided on the inner side of the upper end of the slide rod, a pressing post fixedly connected to one end of the spring, and a plurality of limiting holes arrayed on one side of the fixed tube, the pressing post being slidably connected to adjacent limiting holes.

[0013] In one alternative: the operation buttons are electrically connected to the battery and the motor, respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model replaces the traditional manual pull-rope structure with an electrically driven clamping assembly. A motor drives the threaded rod to rotate, which in turn moves the slider. A guide rod precisely controls the synchronous opening and closing of the two clamping plates, achieving stable and reliable clamping of books. The clamping force, provided by the motor, is constant and sufficient, effectively preventing books from slipping due to human fatigue or inconvenient operation. Simultaneously, the anti-slip strips on the outer side of the clamping plates and the baffles on the inner side work together to increase friction with the book surface and provide lateral restraint, further ensuring clamping stability and minimizing the risk of damage to the books.

[0015] 2. This utility model, through the adjustment components consisting of a fixed tube, sliding rod, pressing column and limiting hole, allows users to quickly adjust the length of the entire device to easily adapt to bookshelves of different heights. The operation buttons are integrated on the handle, enabling one-handed operation while standing, completely eliminating the need to climb ladders, significantly improving the safety and efficiency of book retrieval operations, and greatly reducing the labor intensity of staff.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In one embodiment, such as Figures 1-5 As shown, a library high-position book retrieval auxiliary device includes a mounting base 1, and a clamping component is provided on the upper surface of the mounting base 1; The clamping assembly includes a clamping base 2. A pair of clamping plates 11 are slidably disposed on one side of the clamping base 2. The two clamping plates 11 are symmetrically arranged and one end is disposed on the outside of the clamping base 2. A baffle 15 is fixedly connected to the middle of the adjacent side of the two clamping plates 11. A motor 16 is fixedly connected to one side of the clamping base 2. A threaded rod 17 is disposed in the middle of the clamping base 2 and is driven by the motor 16. The motor 16 is model JGA25-370. The entire device is made of aluminum alloy and weighs between 1.5 and 2 kg. It is lightweight and convenient for one-handed use. A slider 18 is threadedly connected to one end of the threaded rod 17. Several guide rods 19 are symmetrically arranged at both ends of the slider 18. One end of each guide rod 19 is rotatably connected to one side of the adjacent slider 18. Several rotating seats 20 are disposed on the adjacent side of the two clamping plates 11 and are rotatably connected to one end of the adjacent guide rod 19. In this embodiment, when it is necessary to clamp a book, pressing the operation button 6 starts the motor 16. The motor 16 reduces the speed and increases the torque through its built-in reducer, driving the threaded rod 17 to rotate smoothly. The slider 18, which is threaded to the threaded rod 17, moves forward or backward in a straight line. When the slider 18 moves, it pushes or pulls the guide rod 19, which is hinged to both ends of the slider 18. The other end of the guide rod 19 is hinged to the rotating seat 20 fixed on the clamping plate 11, thereby converting the linear motion of the slider 18 into the opposite or opposite motion of the two clamping plates 11, realizing the function of clamping or releasing the book. The baffle 15 set in the middle of the clamping plate 11 can block the spine of the book when clamping, preventing the book from tilting and slipping.

[0024] In one embodiment, such as Figure 3 As shown, a limiting component is provided between the clamping plate 11 and the clamping seat 2. The limiting component works in cooperation with the sliding groove 13 on the clamping seat 2 through the sliding post 14 on the clamping plate 11.

[0025] In one embodiment, such as Figure 3 As shown, the limiting component includes a slide groove 13, which is respectively opened on the upper and lower sides of the clamping base 2. Each of the two clamping plates 11 has a sliding post 14 on one of its upper and lower sides. Each sliding post 14 is slidably connected to the inner side of the adjacent slide groove 13. When the clamping plate 11 is driven to move by the guide rod 19, the sliding post 14 slides along the inner side of the slide groove 13. The slide groove 13 provides precise guidance and limitation for the movement of the clamping plate 11, ensuring that it can only slide smoothly along the predetermined trajectory without deviation or twisting, thereby ensuring that the two clamping plates 11 can always be accurately aligned with the book and achieve stable clamping.

[0026] In one embodiment, such as Figure 2As shown, each of the two clamping plates 11 is provided with a number of anti-slip strips 12 on an adjacent side outside the clamping seat 2 to improve the friction when clamping the book.

[0027] In one embodiment, such as Figure 2 As shown, a battery compartment is provided on one side of the mounting base 1 and a storage battery 10 is installed inside to provide power for starting the motor 16.

[0028] In one embodiment, such as Figure 1 As shown, the lower end of the mounting base 1 is provided with an adjustment component for adjusting the book lifting height.

[0029] In one embodiment, such as Figure 5 As shown, the adjustment assembly includes a fixed tube 3, the upper end of which is fixedly connected to the lower end of the mounting base 1. A slide rod 4 is slidably connected to the lower end of the fixed tube 3, and a handle 5 is fixedly connected to the lower end of the slide rod 4. An operation button 6 is provided on one side of the handle 5. A spring 7 is provided on the inner side of the upper end of the slide rod 4, and a pressing post 8 is fixedly connected to one end of the spring 7. Several limiting holes 9 are arrayed on one side of the fixed tube 3. The pressing post 8 is slidably connected to the adjacent limiting hole 9. In use, the pressing post 8 is pressed down to overcome the elastic force of the spring 7 and exit from the current limiting hole 9. At this time, the user can pull the handle 5 up or down to make the slide rod 4 slide freely in the fixed tube 3. When the device is adjusted to the required height, the pressing post 8 is released, and the spring 7 will push it into the limiting hole 9 corresponding to the position, thereby realizing the relative fixation between the slide rod 4 and the fixed tube 3 and completing the height adjustment.

[0030] In one embodiment, such as Figure 2 As shown, the operation button 6 is electrically connected to the battery 10 and the motor 16 respectively, which facilitates the control of the operation button 6.

[0031] The above embodiment discloses a high-position book retrieval auxiliary device for libraries. The user first adjusts the device length according to the bookshelf height, then presses the pressing post 8 on the handle 5 to disengage it from the limiting hole 9. Next, the user pulls the handle 5 to extend and retract the sliding rod 4 within the fixing tube 3 to a suitable position. Releasing the pressing post 8 allows it to engage with the new limiting hole 9 under the action of the spring 7, completing the fixation. Subsequently, the user holds the handle 5 to lift the device, aligning the two open clamping plates 11 with the target book. Pressing the operation button 6 activates the battery 10, which powers the motor 16. The motor 16 drives the threaded rod 17 to rotate, causing the slider 18 to move towards the book. The slider 18 pushes two sets of guide rods 19, forcing the two clamping plates 11 to close together along the track of the sliding groove 13. The anti-slip strips 12 and baffles 15 securely clamp the sides of the book. To retrieve the book, the device can be retracted directly. To place the book, pressing the operation button 6 again reverses the motor 16, opening the clamping plates 11, and the book is safely placed in the target position.

[0032] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
