Description

Technical Field

[0001] This invention belongs to the field of book storage technology, and specifically relates to a library book storage device. Background Technology

[0002] Traditional book storage methods rely heavily on manual labor to shelving books one by one to fixed heights. For taller shelves, staff need ladders or other climbing equipment, which is not only time-consuming and labor-intensive but also poses safety hazards. While lower shelves can solve these problems, they result in low storage space utilization. Furthermore, existing bookshelf structures are relatively fixed, making it difficult to flexibly adjust book locations according to actual needs. When it's necessary to centrally organize or move books from a specific area, manual handling of each book is often required, leading to low efficiency. Summary of the Invention

[0003] In view of the problems mentioned in the background art above, the present invention provides a library book storage device to solve the problems that when storing books, the higher bookshelves require staff to climb up to operate, which is not only time-consuming and laborious, but also poses certain safety hazards, while the lower bookshelves have low storage space utilization. At the same time, when organizing or moving books, manual handling of each book is often required, which is inefficient.

[0004] The technical solution adopted in this invention is as follows:

[0005] A library book storage device includes a storage rack and a book storage machine. The storage rack includes a main frame with several vertical plates and a placement plate. Book stands are detachably mounted on the placement plate. The vertical plates of the main frame are provided with support beams corresponding to the placement plates. A placement cabinet for placing the book storage machine is provided on one side of the main frame. The book storage machine includes a base with rollers. Two stands are mounted on the base. A mounting plate, a first rotating shaft, a second rotating shaft, and a support mechanism are installed between the two stands. The support mechanism is used to support the placement plates. A first drive wheel is mounted on the first rotating shaft, and a second drive wheel is mounted on the second rotating shaft. The support mechanism is slidably mounted on the stands. A chain is installed between the first drive wheel and the second drive wheel, and both ends of the chain are connected to the support mechanism. A drive assembly with a built-in power supply is mounted on the mounting plate. The drive assembly is drivenly connected to the second rotating shaft. A foot pedal control switch is mounted on the mounting plate for controlling the drive assembly.

[0006] Based on the above technical solution, the present invention has made the following improvements:

[0007] Furthermore, the longitudinal section of the placement plate is trapezoidal, and the four corners of the placement plate are chamfered. The top of the supporting beam is provided with a placement groove that matches the placement plate. The placement plate placed in the placement groove is more stable and will not cause the books on it to fall off.

[0008] Furthermore, the front end of the placement plate has two opposing slots, into which the bookshelf is secured. The bookshelf is easy to disassemble and install, facilitating its removal from the placement plate for storage and transportation.

[0009] Furthermore, the upright frame has a cross groove, and sliding grooves are formed on both sides of the upright frame. The supporting mechanism includes two supporting plates and rolling components. The rolling components include a mounting base and a roller base frame. Several rollers are installed on each roller base frame. The mounting base is located in the cross groove, and the roller base frame is located in the sliding groove. One end of the supporting plate is fixedly connected to the mounting base in the cross groove. A traction rod is connected between the two rolling components. Both ends of the chain are fixedly connected to the traction rod. The supporting plate has a positioning block that matches the end face of the placement plate. When the upright frame contacts the front end of the main frame, the positioning block coincides with the front end of the placement plate placed in the placement groove. The supporting plate moves by sliding in the sliding groove through the rolling components, which has good stability and the included angle between the supporting plate and the upright frame is not easily changed. At the same time, the positioning block positions the placement plate, making it easier to match the placement plate with the placement groove when placing books.

[0010] Furthermore, the second transmission wheel is rotatably mounted on the second rotating shaft via a speed-reducing mechanism. The speed-reducing mechanism includes a first ratchet unit and a second ratchet unit. The first ratchet includes an inner ratchet ring, a fixed ring, and a first pawl. The first pawl is mounted on the fixed ring via an elastic element. The fixed ring is fixedly mounted on the second rotating shaft. The inner ratchet ring is coaxially and fixedly connected to the second transmission wheel. The fixed ring is located in the inner ratchet ring, and the first pawl engages with the inner ratchet ring.

[0011] The second ratchet unit includes a ratchet and a connecting cylinder that are fixedly connected. The ratchet is coaxially connected to the second transmission wheel through the connecting cylinder. A force-applying rod is hinged on the upright. One end of the force-applying rod is provided with a second pawl and a support plate, and the other end is provided with a first foot pedal. A tension spring is connected between the support plate and the upright. When the tension spring is in its initial state, the second pawl engages with the ratchet.

[0012] When the first pawl on the fixed ring engages the inner ratchet ring, driving the second transmission wheel to rotate, it can drive the carrying mechanism to rise via the chain. When the carrying mechanism rises, the second pawl does not restrict the ratchet's rotation; when the second pawl disengages from the ratchet, the first pawl does not restrict the inner ratchet ring's rotation. After placing the book-containing shelf on the main frame, rotating the force lever disengages the second pawl from the ratchet, allowing the carrying mechanism to be quickly lowered by hand without the need for a motor. This improves efficiency and reduces the use of the drive components, thereby reducing power consumption within the drive components and extending the book storage machine's lifespan.

[0013] Furthermore, two columns are installed on the base, and two uprights are slidably fitted onto the two columns respectively. A crossbar is installed between the two uprights, and a pry bar is hinged to the base. One end of the pry bar is located below the crossbar, and the other end is equipped with a second foot pedal. The support plate is moved to the position of the support beam by the drive assembly, and then the columns are raised and lowered slightly by the pry bar. This can be used to place the placement plate on the support beam, avoiding the situation where the placement plate falls instantly after being transported to the support beam by the motor, causing books to vibrate and scatter. The position of the placement plate can be corrected by raising and lowering the columns slightly by the pry bar.

[0014] Furthermore, a fixed wheel frame is installed at the rear end of the base, and a movable wheel frame slides through the front end of the base. A locking screw for securing the movable wheel frame is installed on the base. Rollers are installed on the fixed wheel frame, and casters are installed on the movable wheel frame. The distance between the rollers and casters can be adjusted to improve the stability of the book storage machine, making it less likely to tip over during use. When the book storage machine is not in use, the fixed and movable wheel frames can be retracted into the base to reduce space occupation and facilitate storage.

[0015] Furthermore, a handrail is installed on the stand to facilitate moving the book storage machine.

[0016] The beneficial effects of this invention are:

[0017] During book storage, the books can be placed on the support structure before being arranged, reducing the workload for staff and making book storage more convenient. After the books are arranged, they can be placed on the main shelf using the book storage machine, which eliminates the height restrictions of staff and makes it easier to place books at a higher position, increasing the height of the main shelf and thus increasing the storage capacity and space utilization. When organizing or moving books, they can be moved along with the placement board or lowered in height, which can greatly improve the efficiency of handling and organizing.

Detailed Implementation

[0030] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] like Figure 1 , Figure 8 , Figure 9 As shown, a library book storage device includes a storage rack and a book storage machine 3. The storage rack includes a main frame 1 with several vertical plates and a placement plate 12. Book stands 13 are detachably installed on the placement plate 12. The vertical plates of the main frame 1 are provided with support beams 11 corresponding to the placement plate 12. The placement plate 12 is placed on the support beams 11, which are used to store books. The longitudinal section of the placement plate 12 is trapezoidal, and the four corners of the placement plate 12 are chamfered 121 to facilitate the placement of the placement plate 12 between the vertical plates of the main frame 1. The top of the support beam 11 is provided with a placement groove 111 that matches the placement plate 12. After the placement plate 12 is placed in the placement groove 111, it cannot slide, thus preventing the books from falling when the placement plate 12 is accidentally pushed. The placement plate 12 has two oppositely arranged slots 122 at its front end. The book stand 13 is inserted into the slots 122. When the placement plate 12 needs to be stacked and moved, the book stand 13 can be pulled out along the slots 122, and then the placement plate 12 and the book stand 13 can be stacked separately.

[0033] like Figure 1 , Figure 2 , Figure 7 As shown, a cabinet 2 for placing the book storage machine 3 is provided on one side of the main frame 1. The book storage machine 3 includes a base 31 with rollers, two uprights 33 are mounted on the base 31, a fixed wheel frame 321 is installed at the rear end of the base 31, and a movable wheel frame 322 slides through the front end of the base 31. A locking screw 323 for fixing the movable wheel frame 322 is installed on the base 31. Rollers are installed on the fixed wheel frame 321, and casters are installed on the movable wheel frame 322. The distance between the rollers and casters can be adjusted by adjusting the length of the movable wheel frame 322 extending out of the base 31. Handrails 36 are installed on the uprights 33 to facilitate moving the book storage machine 3.

[0034] like Figure 2 , Figure 3 , Figure 6As shown, an installation plate is installed between two uprights 33, and there are a first rotating shaft 501, a second rotating shaft 502, and a bearing mechanism. A cross groove 331 is opened on the uprights 33, and sliding grooves 332 are opened on both sides of the uprights 33. The bearing mechanism includes two bearing plates 4 and a rolling assembly 41. The rolling assembly 41 includes a mounting base 411 and a roller base frame 412. Several rollers are installed on the roller base frame 412. The mounting base 411 is located in the cross groove 331, the roller base frame 412 is located in the sliding groove 332, and the rollers on the roller base frame 412 slide in contact with the groove wall of the sliding groove 332. One end of the support plate 4 is fixedly connected to the mounting base 411 within the cross groove 331. A traction rod 42 is connected between the two rolling components 41. Both ends of the chain 53 are fixedly connected to the traction rod 42. The support plate 4 is provided with a positioning block 43 that matches the end face of the placement plate 12. When the upright 33 contacts the front end of the main frame 1, the positioning block 43 coincides with the front end of the placement plate 12 placed in the placement groove 111. The support plate 4 is used to support the placement plate 12, and then books are stacked on the placement plate 12. A first drive wheel 51 is mounted on the first rotating shaft 501, and a second drive wheel 52 is mounted on the second rotating shaft 502. The bearing mechanism is slidably mounted on the upright frame 33. A chain 53 is installed between the first drive wheel 51 and the second drive wheel 52. The two ends of the chain 53 are connected to the bearing mechanism. A drive assembly 6 is mounted on the mounting plate. The drive assembly 6 contains a motor and a battery pack. The motor of the drive assembly 6 is connected to the second rotating shaft 502. A foot pedal control switch 63 is mounted on the mounting plate to control the drive assembly 6. The drive assembly 6 drives the second drive wheel 52 to rotate, which drives the chain 53 to move, thereby moving the bearing mechanism to transport the book-containing placement plate 12 to the bearing beam 11 of the main frame 1.

[0035] like Figures 3-5 As shown, the second transmission wheel 52 is rotatably mounted on the second rotating shaft 502 via a descent mechanism. The descent mechanism includes a first ratchet unit and a second ratchet unit. The first ratchet includes an inner ratchet ring 521, a retaining ring 522, and a first pawl 523. The first pawl 523 is mounted on the retaining ring 522 via an elastic element. The retaining ring 522 is fixedly mounted on the second rotating shaft 502. The inner ratchet ring 521 is coaxially and fixedly connected to the second transmission wheel 52. The retaining ring 522 is located within the inner ratchet ring 521, and the first pawl 523 engages with the inner ratchet ring 521. When the second rotating shaft 502 rotates clockwise, the first pawl 523 engages with the inner ratchet ring 521, which drives the second transmission wheel 52 to rotate clockwise, and then drives the bearing plate 4 to rise via the chain 53.

[0036] The second ratchet unit includes a ratchet 72 and a connecting cylinder 71 that are fixedly connected. The ratchet 72 is coaxially connected to the second transmission wheel 52 through the connecting cylinder 71. A force-applying rod 74 is hinged on the upright 33. One end of the force-applying rod 74 is provided with a second pawl 742 and a support plate 743, and the other end is provided with a first foot pedal 741. A tension spring 75 is connected between the support plate 743 and the upright 33. When the tension spring 75 is in its initial state, the second pawl 742 is engaged with the ratchet 72. During the upward movement of the bearing plate 4, the second pawl 742 hooks onto the ratchet 72, which can prevent the second transmission wheel 52 from rotating counterclockwise and prevent the bearing plate 4 from falling under the pressure of the weight of the books. Stepping on the first foot pedal 741 causes the force-applying rod 74 to rotate against the tension spring 75, allowing the second pawl 742 to disengage from the ratchet 72. Then, the bearing plate 4 can be pulled down without relying on the motor. During the downward movement of the bearing plate 4, the second transmission wheel 52 rotates counterclockwise, and the first pawl 523 does not restrict the inner ratchet ring 521. To facilitate pulling the support plate 4, a pull rope can be installed on the traction rod 42. When the height of the support plate 4 exceeds the area that the user can reach, it can be pulled by the pull rope without the need for the chain 53, thus avoiding getting dirt on the hands.

[0037] like Figure 7 , Figure 10 As shown, two columns 30 are installed on the base 31, and two uprights 33 are slidably fitted onto the two columns 30 respectively. A crossbar 34 is installed between the two uprights 33. A pry bar 35 is hinged to the base 31. One end of the pry bar 35 is located below the crossbar 34, and the other end is equipped with a second foot pedal 351. The pry bar 35 moves the placement plate 12 above the bearing beam 11, and the second foot pedal 351 is slowly released to lower the uprights 33 and place the placement plate 12 smoothly on the bearing beam 11. At the same time, if there is an error between the placement plate 12 and the placement slot 111 during the placement process, the pry bar 35 can be used to drive the columns 33 to rise and fall slightly to correct the error. During correction, the second foot pedal 351 is stepped on, and the pry bar 35 pries the crossbar 34 to drive the columns 33 to rise.

[0038] When storing books in the lower section of the storage rack, the placement plate 12 can be placed directly into the placement slot 111 on the supporting beam 11, and then the books can be placed directly on the placement plate 12. When storing books in the middle or upper section of the storage rack, it is too strenuous to directly move and place the books, so the book storage machine 3 can be used. When using the book storage machine 3, first step on the first foot pedal 741 to disengage the second pawl 742 from the ratchet 72, then pull the support plate 4 down to the lower zone. Next, place the placement plate 12, equipped with the book shelf 13, on the support plate 4, ensuring one side of the placement plate 12 contacts the positioning block 43. Then, place the books on the placement plate 12 on the support plate 4. The drive motor then rotates the second shaft 502 clockwise, causing the placement plate 12 to rise. Once the placement plate 12 reaches the target area and is at the same height as the support beam 11, push the book storage machine 3 to change the position of the placement plate 12 so that it aligns with the space between the storage shelf and the two vertical plates. Then, step on the second foot pedal 351, and the pry bar 35 pries the crossbar 34, causing the column 33 to rise and move the placement plate 12 above the support beam 11 (e.g., ...). Figure 10 As shown, push the book storage machine 3 forward so that the upright frame 33 contacts the front end of the main frame 1, and then release the second foot pedal 351 to slowly place the placement plate 12 into the placement slot 111 on the supporting beam 11 to complete the placement of books in the high zone.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
