Description

Technical Field

[0001] The utility model relates to the technical field of book dustproof devices, in particular to a book dustproof device for a library. Background Art

[0002] Libraries are institutions that collect, organize, and preserve books and materials for reading and reference. Established as early as 3000 BC, libraries have the potential to preserve human cultural heritage, develop information resources, and contribute to social education. However, books left unread for extended periods of time accumulate a significant amount of dust, requiring library staff to regularly clean the dust. Currently, manual dust removal is commonly performed, using vacuum cleaners to absorb dust from books. However, when cleaning books placed high up, the vacuum cleaner must be lifted upwards, significantly consuming manual effort and resulting in low efficiency. In order to solve the above technical problems, the patent document with announcement number CN214555602U discloses a dust-proof device for library books, which drives shaft 1 to rotate through motor 1. Shaft 1 can drive shaft 2 to rotate by cooperating with bevel gear 1 and bevel gear 2. Shaft 1 and shaft 2 can drive the brush cylinder on the L-shaped plate to rotate. The dust on the books can be cleaned by the brush cylinder, thereby saving manual labor, improving work efficiency, and ensuring comprehensive cleaning of the books.

[0003] In existing libraries, bookshelves are mostly arranged in parallel. To effectively utilize the space, the distance between adjacent bookshelves is often only enough to accommodate two or three people. However, the existing technology occupies a large area, is not conducive to installation and improvement in existing libraries, and can only clean books on one side. Utility Model Content

[0004] The utility model mainly provides a library book dustproof device, which solves the problems that the prior art occupies a large area as a whole, is not conducive to installation and improvement in the existing library, and can only clean one side of the book.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A library book dustproof device comprises two connecting mechanisms detachably connected to horizontal partitions of a bookshelf, each connecting mechanism being provided with a support frame, a left-right displacement mechanism being detachably connected between the two support frames, a rectangular frame being provided on the left-right displacement mechanism, a lifting plate being slidably connected to the front and rear sides of the rectangular frame, a lifting mechanism being provided on the rectangular frame for driving the lifting plate to move up and down, a vertical brush roller being provided on the inner side of each lifting plate, a vertical power mechanism being provided on the lifting plate for driving the vertical brush roller to rotate, a horizontal brush roller being provided between the two lifting plates, and a horizontal power mechanism being provided on each lifting plate for driving the horizontal brush roller to rotate; one end of a telescopic dust suction tube being connected to the rectangular frame, the other end of the telescopic dust suction tube being connected to an external vacuum cleaner. The other end of the telescopic dust suction tube is connected to the external vacuum cleaner, so that dust generated during cleaning can be absorbed by the external vacuum cleaner. Both the vertical and horizontal brush rollers can utilize a rotating shaft with a cylindrical brush mounted on it. The only difference between the two is the mounting direction and position of the shaft. The shaft can be installed in the corresponding position using any existing mounting connection method, as long as it does not affect its rotation. Both the vertical and horizontal power mechanisms can utilize an electric motor in conjunction with existing transmission components to transmit power to the corresponding shaft, driving the corresponding rotation. The length of the vertical brush roller is selected and designed based on specific practical needs. Existing transmission components include gears, transmission belts, and transmission chains. During use, the left and right displacement mechanisms are installed between the two support frames, and then the connecting mechanism is installed and connected to the horizontal partition of the bookshelf; during the cleaning process, the external vacuum cleaner is connected to the other end of the telescopic vacuum tube, and then the lifting plate is driven down by the lifting mechanism to make the vertical brush roller and the horizontal brush roller drop to corresponding positions, so that the vertical brush roller is located on both sides of the book, and the horizontal brush roller is located on the upper side of the book, and the vertical brush roller is driven to rotate by the vertical power mechanism, and the horizontal brush roller is driven to rotate by the horizontal power mechanism, and the rectangular frame is driven to move in conjunction with the left and right displacement mechanisms, so as to clean the upper side and both sides of the book, and then the external vacuum cleaner is used in conjunction with the rectangular frame to absorb the cleaned dust.By adopting the structure of the present application, the two sides of the book can be cleaned by the vertical brush rollers on both sides, and the upper side of the book can be cleaned by the horizontal brush roller on the upper side, effectively increasing the cleaning surface, and the dust generated by cleaning can be absorbed by the cooperation of an external vacuum cleaner; at the same time, the lifting plate is driven by the lifting mechanism, thereby driving the vertical brush roller and the horizontal brush roller to move up and down, and the corresponding components can be raised toward each other when cleaning is not required, so that some components enter the rectangular frame, increasing the space on the lower side, thereby facilitating the taking and placing of books, and when cleaning is required, the vertical brush roller and the horizontal brush roller can be lowered to the corresponding position, so that the vertical brush roller is located on both sides of the book and the horizontal brush roller is located on the upper side of the book; the rectangular frame can be driven to move by the left and right displacement mechanism, thereby driving the vertical brush roller and the horizontal brush roller to move to clean the books; at the same time, the present application detachably connects each component to the horizontal partition of the bookshelf through a connecting mechanism, so as to clean the books on the lower side, and effectively reduces the space occupied by the installation compared with the prior art, and the connecting mechanism can be directly installed on the existing bookshelf, thereby effectively reducing the cost.

[0007] Furthermore, the connecting mechanism includes a transverse plate, with side brackets provided on the front and rear sides of the transverse plate. The side brackets are provided with clamping assemblies for clamping the transverse partitions. The support frame is provided on the underside of the transverse plate. When in use, the clamping assemblies clamp the transverse partitions of the bookshelf, thereby fixing them to the underside of the transverse partitions and achieving stability of all components. The structure is simple and practical.

[0008] Furthermore, the clamping assembly includes a clamping cylinder mounted on the side bracket, with an L-shaped clamping plate disposed at the inner end of the clamping cylinder. With this structure, the two clamping cylinders can each drive the respective L-shaped clamping plates to move inward, thereby allowing the upper horizontal surfaces of the two L-shaped clamping plates to be hung on the horizontal partitions of the bookshelf. The two clamping cylinders then continue to drive the two L-shaped clamping plates to move inward until the vertical surfaces of the L-shaped clamping plates stably clamp the front and rear side surfaces of the horizontal partitions. The method of first hanging and then clamping can reduce the difficulty of installation for the staff; when the L-shaped clamping plates are hung, their upper horizontal surfaces are no longer connected to the upper side surfaces of the horizontal partitions, allowing them to move relative to each other.

[0009] Furthermore, the left-right displacement mechanism includes a displacement screw rotatably connected to the two support frames, a displacement guide rod fixedly connected between the two support frames, and a first motor disposed on either support frame for driving the displacement screw to rotate; a displacement block is threadedly connected to the displacement screw, and the displacement block is slidably connected to the displacement guide rod; and the rectangular frame is detachably connected to the displacement block. The first motor can use any transmission component known in the art to transmit power to the displacement screw, as long as it can drive the displacement screw to rotate. The rectangular frame can be detachably connected to the displacement block using any detachable connection method known in the art, as long as it can be fixed to the displacement block. With this structure, the displacement screw can be driven to rotate by the first motor, so that the displacement block is displaced by the displacement screw when limited by the displacement guide rod. During the displacement process, the displacement block can also drive the rectangular frame, which is detachably connected to it, to displace. The detachable connection between the rectangular frame and the displacement block allows the connection mechanism and the left-right displacement mechanism to be installed first, followed by the rectangular frame, thereby enabling step-by-step installation and reducing installation difficulty.

[0010] Furthermore, the lifting mechanism includes a linear slide rail provided on the rectangular frame, a second motor provided on the rectangular frame, and a lifting block provided on the lifting plate; the lifting plate is provided on the linear slide rail, and the output end of the second motor is provided with a lifting screw extending through the rectangular frame, and the lifting screw is threadedly connected to the lifting block. The output end of the second motor extends through the rectangular frame and is fixedly connected to the lifting screw, and a shaft seal can be used to achieve sealing with the rectangular frame. With this structure, the lifting screw can be driven to rotate by the second motor, so that the lifting plate can cooperate with the lifting block to drive the corresponding components to move up and down when the linear slide rail is limited, thereby achieving lifting movement.

[0011] Furthermore, the lifting plate includes an outer plate disposed on the linear slide rail, a distance adjustment assembly disposed on the outer plate, an inner plate disposed on the distance adjustment assembly, the vertical brush roller and the vertical power mechanism disposed on the inner plate, and the transverse brush roller and the transverse power mechanism disposed on the outer plate. The motor of the vertical power mechanism can be disposed on the outer side of the inner plate, and the motor of the transverse power mechanism can be disposed on the outer side of the outer plate or on the top of the outer plate, thereby avoiding affecting the cleaning of the front and back sides of the books. The motor of the transverse power mechanism can be driven to the rotating shaft of the transverse brush roller using components such as a transmission belt or a transmission chain. With this structure, the position of the inner plate can be adjusted through the distance adjustment assembly, thereby achieving adjustment of the distance between the two inner plates, thereby accommodating cleaning of books of different widths and avoiding a large distance between the vertical brush roller and the books, which would result in a reduced cleaning effect. Furthermore, since the transverse brush roller is mounted on the outer plate, it does not affect the adjustment of the inner plate and can move up and down with the outer plate.

[0012] Furthermore, the distance adjustment assembly includes an adjustment screw threadedly connected to the outer plate and an adjustment guide rod slidably connected to the outer plate. The inner end of the adjustment screw is rotatably connected to the inner plate, and the inner end of the adjustment guide rod is fixedly connected to the inner plate. With this structure, the distance between the inner plates can be adjusted by rotating the adjustment screw, thereby cooperating with the adjustment guide rod. The adjustment structure is simple and practical.

[0013] Furthermore, the invention comprises two transverse brush rollers, which are arranged between the two outer plates on opposite sides of the inner plate. With this structure, the two transverse brush rollers are arranged between the two outer plates on opposite sides of the inner plate, which can effectively avoid the situation where the transverse brush roller is arranged on one side and the upper side of the book is not thoroughly cleaned, or the upper side of the book is not cleaned.

[0014] Beneficial effects: With the structure of the present application, the two sides of the book can be cleaned by the vertical brush rollers on both sides, and the upper side of the book can be cleaned by the horizontal brush roller on the upper side, which effectively increases the cleaning surface and can absorb the dust generated by cleaning with the cooperation of an external vacuum cleaner; at the same time, the lifting plate is driven by the lifting mechanism, thereby driving the vertical brush roller and the horizontal brush roller to move up and down, and the corresponding components can be raised toward each other when cleaning is not required, so that some components enter the rectangular frame, increasing the space on the lower side, thereby facilitating the taking and placing of books, and when cleaning is required, the vertical brush roller and the horizontal brush roller can be lowered to the corresponding position, so that the vertical brush roller is located on both sides of the book and the horizontal brush roller is located on the upper side of the book; the rectangular frame can be driven to move by the left and right displacement mechanism, thereby driving the vertical brush roller and the horizontal brush roller to move to clean the books; at the same time, the present application detachably connects each component to the horizontal partition of the bookshelf through a connecting mechanism, thereby cleaning the books on the lower side, and effectively reduces the space occupied by the installation compared to the prior art, and the connecting mechanism can be directly installed on the existing bookshelf, thereby effectively reducing the cost.
