Description

Technical Field

[0001] This invention relates to the field of mobile shelving technology, and more particularly to a moisture-proof and dust-proof mobile shelving for protecting paper documents. Background Technology

[0002] Mobile shelving is a type of high-density equipment for centralized management of items. Due to its advantages such as good confidentiality, strong sealing, high space utilization, and convenient access, mobile shelving is commonly used to store paper documents.

[0003] Patent application CN211795176U, published on October 30, 2020, discloses a mobile shelving unit for urban construction archives management. The unit includes a mobile shelving body, handles, a pulley fixing block, and pulleys. Sliding tracks are installed on the inner walls of both sides of the mobile shelving body, and shelves are connected to the internal pulleys of the sliding tracks. Dividers are installed above each shelf, and labels are provided on the outer rear side of each shelf. Handles are installed on both sides of the mobile shelving body, and door frames are installed on the outer rear side of the mobile shelving body. Dustproof glass is installed on the inner side of each door frame, and door handles are provided on the outer rear side of each door frame. A first rotating rod is provided on the outer side of each door frame.

[0004] The aforementioned patents cannot dry the inside of the mobile shelving unit. When the mobile shelving unit is opened, the moisture that enters is not easily removed, and the documents are easily damaged by the moisture. Moreover, the aforementioned patents do not have a dust removal function, and dust easily accumulates inside the mobile shelving unit, causing the documents to become dusty and affecting their usability. Therefore, we have designed a moisture-proof and dust-removing mobile shelving unit for paper document protection that dries the inside of the mobile shelving unit and has a dust removal function to solve the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the above-mentioned patents that cannot dry the inside of the mobile shelving unit and do not have a dust removal function, the present invention provides a moisture-proof and dust-removing mobile shelving unit for protecting paper documents that can dry the inside of the mobile shelving unit and has a dust removal function.

[0006] A moisture-proof and dust-proof mobile shelving unit for protecting paper documents includes an outer shell, hinges, doors, shelves, and a vacuum cleaner. Hinges are symmetrically hinged on the upper and lower parts of the left front side of the outer shell, and doors are installed between the hinges. Shelves are installed from top to bottom on the left and right sides of the inner wall of the outer shell, and vacuum cleaners are connected to each shelf. The unit also includes a drying mechanism and a ventilation mechanism. The inner top wall of the outer shell is provided with a drying mechanism for drying the paper documents on the shelves, and the rear wall of the outer shell is provided with a ventilation mechanism for exchanging air between the inside and outside of the outer shell.

[0007] Furthermore, the drying mechanism includes a dryer, a first circular hood, a hose, an air supply pipe, a slide rail, a slider, and spray heads. The dryer is installed on the top wall of the inner shell, and the bottom of the dryer is the air outlet. The first circular hood is installed at the bottom of the dryer, and a hose is installed at the bottom of the first circular hood. The hose is connected to the first circular hood, and part of the hot air from the dryer enters the hose through the first circular hood. The bottom end of the hose is connected to the air supply pipe, which has high rigidity. The air supply pipe is connected to the hose, and spray heads are evenly connected from top to bottom at the bottom of the air supply pipe. Each spray head corresponds to a shelf, and the spray head is located above and behind the corresponding shelf. A slide rail is installed from top to bottom on the rear side of the inner wall of the outer shell. The slide rail and shelf are distributed alternately. Slider blocks are slidably connected inside the slide rail, and each slider is connected to the air supply pipe.

[0008] Furthermore, the ventilation mechanism includes a second circular cover, a first fixed rod, a limiting block, a first toothed rod, a first gear, and a rotating handle. Both the left and right sides of the outer shell have ventilation holes, which are evenly distributed from top to bottom. The first gear is rotatably connected to the middle of the rear wall of the outer shell, and the rotating handle is connected to the rear side of the first gear. Limiting blocks are installed on both the left and right sides of the rear wall of the outer shell. The first toothed rod is slidably connected between the limiting blocks on the left side, and the first toothed rod is also slidably connected between the limiting blocks on the right side. The two first toothed rods are located on the left and right sides of the first gear, respectively, and both first toothed rods mesh with the first gear. A first fixed rod is installed on each first toothed rod from top to bottom, and a second circular cover is connected to each first fixed rod. Each second circular cover corresponds to a ventilation hole on the outer shell, and the second circular cover blocks the corresponding ventilation hole on the outer shell.

[0009] Furthermore, it also includes an adjustment mechanism for driving the spray head to move left and right to expand the drying area. The adjustment mechanism includes a loop, a double helix rod, a second gear, a motor, and a first fixed ring. The first fixed ring is installed on the bottom wall of the outer casing, and the motor is installed inside the first fixed ring. The left end of the output shaft of the motor is keyed to the second gear. The loop is installed on the bottom slider. The double helix rod is rotatably connected to the bottom side of the outer casing. The loop and the double helix rod are threadedly connected. The second gear is installed on the left side of the double helix rod, and the two second gears mesh with each other.

[0010] Furthermore, it also includes a rotating mechanism for adjusting the airflow direction entering the housing. The rotating mechanism includes a second fixed ring, a first baffle, a transmission component, and an air collecting duct. The second fixed rings are symmetrically installed in front and behind on both sides of the inner wall of the housing. The first baffle is rotatably connected between two adjacent second fixed rings in the horizontal direction. The transmission component is wound around two adjacent first baffles in the vertical direction. Air collecting ducts are installed from top to bottom on both sides of the inner wall of the housing. Each air collecting duct corresponds to a ventilation hole on the housing. The air collecting ducts on the left are all located to the right of the corresponding ventilation hole on the left side of the housing, and the air collecting ducts on the right are all located to the left of the corresponding ventilation hole on the right side of the housing.

[0011] Furthermore, it also includes a swing mechanism for driving the first baffle to rotate inward and outward. The swing mechanism includes a third gear, a second rack, a second fixed rod, a third fixed rod, a spring, and a limiting rod. At least four sets of third fixed rods are evenly installed from top to bottom on both the left and right sides of the rear side of the inner wall of the outer shell. The third fixed rods on the left and right sides are staggered. A second fixed rod is slidably connected between each set of third fixed rods. A limiting rod is rotatably connected to the inner end of each second fixed rod. The air supply pipe slides left and right to squeeze the limiting rod. A spring is wound around each of the second fixed rods. The inner and outer ends of the springs are respectively connected to the limiting rod and the third fixed rod. A second rack is connected to the outer end of each second fixed rod. A third gear is fixedly connected to the rear end of the first baffle that is close to the second rack. The third gear meshes with the adjacent second rack.

[0012] Furthermore, it also includes a control mechanism for removing the drying dead corners inside the outer shell. The control mechanism includes a fixed block, a fixed shaft, and a second baffle. Two fixed blocks are installed on the upper rear side of the inner wall of the outer shell. The two fixed blocks are located on the left and right sides of the dryer, respectively. A fixed shaft is installed on each fixed block, and a second baffle is rotatably connected to each fixed shaft. Both second baffles are inclined inward and downward.

[0013] Furthermore, it also includes torsion springs, with torsion springs wrapped around both the upper and lower parts of the limiting rod. The inner and outer ends of the torsion springs are respectively connected to the limiting rod and the second fixing rod of the outer shell. The elastic coefficient of the torsion spring is much greater than that of the spring.

[0014] The beneficial effects are:

[0015] 1. The dryer outputs hot air to dry the inside of the outer shell. The dryer also inputs some hot air into the first circular hood and sprays it out from the nozzle through the hose and air supply pipe, thereby drying the paper documents on the shelf, preventing the paper documents from getting damp and helping to keep the paper documents intact.

[0016] 2. When the vacuum cleaner is working, it sucks up dust, which helps keep the inside of the casing clean;

[0017] 3. The second circular cover moves downwards and separates from the ventilation holes on the outer shell. The outer shell can use the ventilation holes on the outer shell to exchange air inside and outside, thereby deodorizing the inside of the outer shell and helping to prevent paper documents from producing odors.

[0018] 4. The left and right movement of the slider drives the air supply pipe to move left and right, which in turn drives the spray head to move left and right, which can expand the drying area and improve the drying effect.

[0019] 5. After the air enters the shell through the air collection duct, people move the first baffle from the inside out. The first baffle rotates outward, which in turn causes the lower first baffle to rotate inward and outward through the transmission component. This can adjust the airflow direction entering the corresponding ventilation hole on the shell and speed up the airflow, which helps to enhance the ventilation effect.

[0020] 6. The rotation of the third gear drives the first baffle to rotate, thus eliminating the need for manual rotation of the first baffle, saving manpower and simplifying operation;

[0021] 7. By rotating the second baffle inward, hot air is concentrated along the inner wall of the second baffle, which can dry the area directly below the first circular cover, eliminating the drying dead corners inside the shell and facilitating the complete drying of the inside of the shell.

Detailed Implementation

[0041] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0042] Example 1

[0043] A type of moisture-proof and dust-proof mobile shelving unit for protecting paper documents, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it includes an outer shell 1, hinges 2, doors 3, shelves 4, vacuum cleaners 41, drying mechanisms 5, and ventilation mechanisms 6. There are two hinges 2, which are respectively hinged to the upper and lower parts of the front left wall of the outer shell 1. The door 3 is installed between the two hinges 2. Four shelves 4 are installed from top to bottom between the left and right sides of the inner wall of the outer shell 1. Vacuum cleaners 41 are connected to each shelf 4. The drying mechanism 5 is provided on the inner top wall of the outer shell 1, and the ventilation mechanism 6 is provided on the rear wall of the outer shell 1.

[0044] like Figure 2 , Figure 5 and Figure 6 As shown, the drying mechanism 5 includes a dryer 51, a first circular cover 52, a hose 53, an air supply pipe 54, a slide rail 55, a slider 56, and a spray head 57. The dryer 51 is installed on the inner top wall of the outer casing 1, and the bottom of the dryer 51 is the air outlet. The first circular cover 52 is fixed to the bottom of the dryer 51, and a hose 53 is fixed to the bottom of the first circular cover 52. The hose 53 is connected to the first circular cover 52, and part of the hot air from the dryer 51 enters the hose 53 through the first circular cover 52. The air supply pipe 54 is fixed to the hose 55. At the bottom of pipe 53, air supply pipe 54 has high rigidity and is connected to flexible hose 53. Three spray heads 57 are fixedly connected from top to bottom at the lower part of air supply pipe 54. Each spray head 57 is connected to air supply pipe 54. Each spray head 57 corresponds to a shelf 4. The spray head 57 is located above and behind the corresponding shelf 4. Four slide rails 55 are welded from top to bottom on the rear side of the inner wall of outer shell 1. The slide rails 55 are distributed alternately with the shelf 4. Each slide rail 55 has a slider 56 slidably connected inside. The slider 56 is connected to air supply pipe 54.

[0045] like Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, the ventilation mechanism 6 includes a second circular cover 61, a first fixing rod 62, a limiting block 63, a first gear 64, a first gear 65, and a rotating handle 66. The outer casing 1 has four ventilation holes on both the left and right sides, evenly distributed from top to bottom. The first gear 65 is rotatably connected to the middle of the rear wall of the outer casing 1. The rotating handle 66 is welded to the rear side of the first gear 65. Limiting blocks 63 are symmetrically welded to the upper and lower parts of both sides of the rear wall of the outer casing 1. There are two first gears 64, one of which slides... One first gear 64 is slidably connected between the two limiting blocks 63 on the left and the other first gear 64 is slidably connected between the two limiting blocks 63 on the right. The two first gears 64 are located on the left and right sides of the first gear 65 respectively. The first gears 64 mesh with the first gear 65. Four first fixing rods 62 are welded from top to bottom on each first gear 64. A second circular cover 61 is fixed to each first fixing rod 62. Each second circular cover 61 corresponds to a ventilation hole on the outer shell 1. The second circular cover 61 blocks the corresponding ventilation hole on the outer shell 1.

[0046] Initially, the second circular cover 61 blocks the corresponding ventilation holes on the outer shell 1. When paper documents need to be stored, people first turn to open the door 3, then place the paper documents on the designated shelf 4, and then turn to close the door 3, thus completing the storage of the paper documents. Because the second circular cover 61 blocks the corresponding ventilation holes on the outer shell 1, the door 3 seals the outer shell 1, thus preventing external moisture and dust from entering the outer shell 1, achieving basic moisture and dust protection functions. When the door 3 is opened, external moisture and dust enter the door 3, damaging the paper documents. In order to ensure the integrity of the paper documents, it is necessary to dry and remove dust from the inside of the outer shell 1 in a timely manner. When the dryer 51 is turned on, it outputs hot air to dry the inside of the outer casing 1. The dryer 51 also directs some of the hot air into the first circular hood 52, and through the hose 53 and air supply pipe 54, the hot air is sprayed out from the nozzle 57 to dry the paper documents on the shelf 4, preventing them from getting damp and ensuring their integrity. When it is necessary to clean the inside of the outer casing 1, the vacuum cleaner 41 is turned on to remove the dust, keeping the inside of the outer casing 1 clean. After cleaning, the vacuum cleaner 41 is turned off. Due to prolonged use, odors may easily develop inside the outer casing 1, so it needs to be cleaned periodically. Ventilation is provided to the outer casing 1. When ventilation is needed, the handle 66 is turned clockwise, causing the first gear 65 to rotate clockwise. This causes the right-side first gear 64 to slide downwards, which in turn causes the right-side first fixing rod 62 to move the second circular cover 61 downwards, disengaging it from the corresponding ventilation hole on the right side of the outer casing 1. The clockwise rotation of the first gear 65 causes the left-side first gear 64 to move upwards, which in turn causes the left-side second circular cover 61 to move upwards, disengaging it from the corresponding ventilation hole on the left side of the outer casing 1. This allows for air exchange between the inside and outside of the outer casing 1 through the corresponding ventilation holes, effectively deodorizing the outer casing 1. To prevent paper documents from producing odors, when ventilation of the outer casing 1 is not required, rotate the handle 66 counterclockwise, causing the first gear 65 to rotate counterclockwise. This causes the first toothed rod 64 on the right to slide upward, which in turn causes the second circular cover 61 on the right to move downward through the first fixing rod 62 on the right, blocking the corresponding ventilation hole on the right side of the outer casing 1. The first gear 65 rotates counterclockwise, causing the first toothed rod 64 on the left to slide downward. This causes the second circular cover 61 on the left to move downward through the first fixing rod 62 on the left, blocking the corresponding ventilation hole on the left side of the outer casing 1. At this time, the outer casing 1 stops exchanging air with the outside air. Then, release the handle 66.

[0047] Example 2

[0048] Based on Example 1, such as Figure 2 , Figure 9 and Figure 10As shown, it also includes an adjustment mechanism 7, which includes a loop 71, a double helix rod 72, a second gear 73, a motor 74, and a first fixing ring 75. The first fixing ring 75 is welded to the bottom wall of the outer casing 1. The motor 74 is installed inside the first fixing ring 75. The left end of the output shaft of the motor 74 is keyed to the second gear 73. The loop 71 is fixed to the bottom slider 56. The double helix rod 72 is rotatably connected to the lower bottom of the outer casing 1. The loop 71 and the double helix rod 72 are threadedly connected. The left side of the double helix rod 72 is welded to the second gear 73, and the two second gears 73 mesh with each other.

[0049] To improve the drying effect and expand the drying area, the spray head 57 can be moved left and right. At this time, the motor 74 can be started. The output shaft of the motor 74 rotates, which drives the second gear 73 at the front to rotate, which in turn drives the second gear 73 at the rear to rotate, which in turn drives the double helical rod 72 to rotate, which in turn drives the loop 71 to move left and right. The left and right movement of the loop 71 drives the slider 56 to move left and right, which drives the air supply pipe 54 to move left and right, which in turn drives the spray head 57 to move left and right. This can expand the drying area and improve the drying effect. When the inside of the outer shell 1 is dried, the dryer 51 can be turned off.

[0050] like Figure 2 , Figure 11 and Figure 12 As shown, it also includes a rotating mechanism 8, which includes a second fixed ring 81, a first baffle 82, a transmission assembly 83, and an air collecting duct 84. Eight second fixed rings 81 are symmetrically installed on the left and right sides of the inner wall of the outer shell 1, front and back. A first baffle 82 is rotatably connected between two adjacent second fixed rings 81 in the horizontal direction. A transmission assembly 83 is wound around two adjacent first baffles 82 in the vertical direction. The transmission assembly 83 consists of two pulleys and a flat belt. The two pulleys are respectively connected to two adjacent first baffles 82 in the vertical direction, and the flat belt is wound around two adjacent pulleys. Four air collecting ducts 84 are fixed from top to bottom on the left and right sides of the inner wall of the outer shell 1. Each air collecting duct 84 corresponds to a ventilation hole on the outer shell 1. The air collecting ducts 84 on the left are all located to the right of the corresponding ventilation hole on the left side of the outer shell 1, and the air collecting ducts 84 on the right are all located to the left of the corresponding ventilation hole on the right side of the outer shell 1.

[0051] With the second circular cover 61 disengaging from the corresponding ventilation hole on the outer shell 1, allowing air exchange between the inside and outside of the outer shell 1, air enters the interior of the outer shell 1 through the air collection tube 84. Subsequently, the first baffle 82 is moved inward and outward. The first baffle 82 rotates outward and through the transmission component 83, causing the lower first baffle 82 to rotate inward and outward. This can adjust the airflow direction entering the corresponding ventilation hole on the outer shell 1, while accelerating the airflow speed, which is beneficial to enhancing the ventilation effect.

[0052] like Figure 2 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 As shown, it also includes a swing mechanism 9, which includes a third gear 91, a second rack 92, a second fixed rod 93, a third fixed rod 94, a spring 95, a limiting rod 96, and a torsion spring 97. Four sets of third fixed rods 94 are evenly installed from top to bottom on both the left and right sides of the rear inner wall of the outer casing 1. Two third fixed rods 94 form a group, and the third fixed rods 94 on the left and right sides are staggered. A second fixed rod 93 is slidably connected between each group of third fixed rods 94. A limiting rod 96 is rotatably connected to the inner end of each second fixed rod 93. The air supply pipe 54 slides left and right, compressing the limiting rod. Springs 95 are wound around the limiting rod 96 and the second fixed rod 93. The inner and outer ends of the springs 95 are connected to the limiting rod 96 and the third fixed rod 94, respectively. The outer end of the second fixed rod 93 is fixedly connected to the second toothed rod 92. The rear end of the first baffle 82, which is close to the second toothed rod 92, is fixedly connected to the third gear 91. The third gear 91 meshes with the second toothed rod 92. Torsion springs 97 are wound around both the upper and lower parts of the limiting rod 96. The inner and outer ends of the torsion springs 97 are connected to the limiting rod 96 and the second fixed rod 93, respectively. The elastic coefficient of the torsion spring 97 is much greater than that of the spring 95.

[0053] The leftward movement of the air supply duct 54 causes the left-side limiting rod 96 to move to the left, which in turn causes the right-side second fixed rod 93 to slide to the left. At this time, the right-side spring 95 is stretched, which in turn causes the right-side second gear 92 to move to the left. This, in turn, causes the right-side first baffle 82 to rotate inward through the right-side third gear 91. When the right-side second fixed rod 93 slides to its left limit, the right-side spring 95 is stretched to its limit. Subsequently, the leftward movement of the air supply duct 54 compresses the left-side limiting rod 96, causing the left-side limiting rod 96 to rotate. At this time, the left-side torsion spring 97 undergoes torsional deformation. Then, the air supply duct 54 passes over the left side. The limiting rod 96 continues to move to the left. At this time, the left torsion spring 97 resets, causing the left limiting rod 96 to reverse. The right spring 95 resets, causing the right second fixing rod 93 to slide to the right. The right second fixing rod 93 slides to the right, driving the right second gear 92 to move to the right. This, in turn, drives the right first baffle 82 to rotate outward through the right third gear 91. Similarly, during the movement of the air supply pipe 54 to the right, the left third gear 91 drives the left first baffle 82 to rotate outward. Therefore, there is no need to manually rotate the first baffle 82, which helps to save manpower and simplify operation.

[0054] like Figure 2 and Figure 18As shown, it also includes a control mechanism 10, which includes a fixing block 101, a fixing shaft 102, and a second baffle 103. Two fixing blocks 101 are welded to the upper rear side of the inner wall of the outer casing 1. The two fixing blocks 101 are located on the left and right sides of the dryer 51, respectively. A fixing shaft 102 is fixedly connected to each fixing block 101. A second baffle 103 is rotatably connected to each fixing shaft 102. Both second baffles 103 are inclined inward and downward.

[0055] Because the area directly below the first circular cover 52 is blocked by the first circular cover 52, it is not easy to be dried by hot air. In order to dry the area directly below the first circular cover 52, the second baffle 103 can be rotated inward, so that the hot air is concentrated along the inner wall of the second baffle 103, thereby drying the area directly below the first circular cover 52, eliminating the drying dead corners inside the outer shell 1, and facilitating the complete drying of the inside of the outer shell 1. Then, the second baffle 103 can be rotated inward and outward, so that the hot air is blown along the inner wall of the second baffle 103 to different areas inside the outer shell 1, thereby further expanding the drying area and further improving the drying efficiency.

[0056] It should be understood that the above description is for illustrative purposes only and is not intended to limit the invention. Those skilled in the art will understand that variations of the invention are included within the scope of the claims herein.
