Description

Technical Field

[0001] This invention relates to the field of archive rack technology, and in particular to a moisture-proof archive rack for archive management. Background Technology

[0002] As vital information carriers, the long-term security of archives relies heavily on a dry and well-ventilated environment. However, existing moisture-proof archive racks for archival management present numerous unresolved issues in practical applications. To maximize space utilization, archive boxes are often densely stacked on the shelves. This stacking method directly obstructs airflow between the boxes, allowing moisture from the outside environment to easily accumulate in the enclosed spaces, making it difficult for it to dissipate naturally. This leads to problems such as damp and softened paper, blurred handwriting, and even mold growth. Furthermore, the densely stacked boxes compress each other, making them difficult to remove and cumbersome. While some archive racks attempt to improve ventilation by separating the boxes with partitions, the lack of stable support makes the boxes susceptible to displacement and wear on the edges. Summary of the Invention

[0003] The main objective of this invention is to provide a moisture-proof file rack for file management, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A moisture-proof file rack for file management includes a file management rack.

Two sets of support plates are fixedly disposed at the front end of the fixing plate corresponding to the position of the positioning rod. A first guide cylinder is fixedly disposed on the front side of each of the two sets of support plates. A first triangular opening is opened at the rear side of each of the two sets of first triangular openings. Two sets of movable openings are disposed between the two sets of first triangular openings. A second guide cylinder is fixedly disposed at the front end of the fixing plate near the two sets of support plates. Four sets of second triangular openings are opened at the front side of the second guide cylinder. A circular opening is opened at the front side of the cavity sleeve corresponding to the position of the positioning rod.

[0006] Preferably, a shielding frame is fixedly installed at the upper end of the file management rack near the rear side, an air-gathering pipe is fixedly installed inside the shielding frame, a drying fan is fixedly installed at the upper end of the air-gathering pipe, a main air pipe is fixedly installed at the lower end of the air-gathering pipe, three sets of branch air pipes are fixedly installed on both sides of the main air pipe, and an air vent is opened at the front of the six sets of branch air pipes. Several sets of air guide grooves are opened at the upper end of the placement plate, and several sets of air guide plates are fixedly installed inside the several sets of air guide grooves.

[0007] Preferably, several sets of partition plates are evenly distributed laterally on the upper side of the placement plate, and the sliding grooves on both sides of the several sets of partition plates are staggered.

[0008] Preferably, the U-shaped frame is slidably disposed between two adjacent sets of partition plates, the front side of the U-shaped frame is inclined at the square groove position and is made of elastic deformable material, and the positioning film is made of rubber.

[0009] Preferably, the cavity sleeve is assembled by splicing, the positioning rod is adapted to the circular opening, the positioning rod is set in a vertical position, and the damping spring plate elastically presses against the front end of the rotating shaft, and the rotating shaft and the cavity sleeve are set for damped rotation.

[0010] Preferably, the two sets of movable openings are adapted to the positioning rod, the tips of the upper and lower sets of the four sets of second triangular openings correspond to the positions of the two sets of movable openings, and the tips of the other two sets of the four sets of second triangular openings correspond to the inner positions of the two sets of first triangular openings.

[0011] Preferably, the main air tube is fixedly installed on the inner side of the inner partition, the six sets of branch air tubes are respectively fixedly installed on the rear side of the six sets of placement plates, the air inlet corresponds to the position of the air guide groove, and the air guide plate structure is arc-shaped and upwardly set.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. When placing the file box, first insert the file box into the two sets of U-shaped brackets between the two adjacent sets of partitions. Push the positioning rod backward through the round opening, compressing the spring. The vertically positioned positioning rod passes between the two corresponding sets of movable openings on the rear side. The positioning rod moves backward and contacts the second triangular opening on the upper and lower sides. The inclined surface of the second triangular opening causes the positioning rod and the rotating shaft to rotate clockwise. When the bottom of the second triangular opening is reached, resistance is generated. After releasing the file box, the compressed spring pulls the positioning rod towards the first guide cylinder, where it contacts the inclined surface of the first triangular opening. The guide rotates to the bottom of the first triangular opening, aligning the positioning rod with the inclined surfaces of the second triangular openings on both sides. Simultaneously, the positioning rod is confined within the first guide cylinder by the first triangular opening. The confined positioning rod positions the file box within the partition plate. When removing the file box, push the desired file box. Similarly, the positioning rod contacts and rotates with the second triangular openings on both sides. With the push of the spring, it is guided by the two sets of first guide cylinders to the positions of the two movable openings, automatically releasing the positioning rod. The springs can then push the two sets of U-shaped frames and file boxes outwards individually for easy access and use by the operator.

[0013] 2. When the file box is inserted between the two sets of U-shaped shelves and pushed inward, the two sets of U-shaped shelves slide along the corresponding sliding grooves. The inclined position of the front of the U-shaped shelf and the positioning film move accordingly, moving to the inner position of the two sets of partitions. The positioning film at the inclined position of the U-shaped shelf is pushed and clamped on both sides of the file box by the partitions, thereby stabilizing the file box inserted between the two sets of partitions and reducing the shaking of the stored file box. At the same time, the partitions separate each set of file boxes, and the clamping of the two sets of positioning films reduces contact with the partitions, creating a certain gap between each set of file boxes and improving the overall ventilation.

[0014] 3. The drying fan blows air from the main air duct into the six sets of branch air ducts, which then blow the air through the vents into several sets of air guide slots on the placement plate. These air guide slots ventilate the bottom of the file boxes, creating an airflow channel that prevents moisture from accumulating and keeps the air around the file boxes dry. Additionally, several sets of air guide plates on the inside guide the airflow upwards, blowing it into the gaps between each set of file boxes, thus optimizing the drying and moisture-proofing of the file boxes.

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship as a relative relationship of orientation or position, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0019] Please see Figures 1-9 An embodiment of the present invention provides a moisture-proof file rack for file management, comprising a file management rack 1, an inner partition 2 fixedly disposed in the middle of the inner side of the file management rack 1, three sets of placement plates 3 fixedly disposed at both ends of the inner partition 2, six sets of dividing components 4 disposed on the upper side of the three sets of placement plates 3 near the two sides of the inner side of the file management rack 1, and a pushing component 5 disposed inside the rear side of each of the six sets of dividing components 4, a plurality of file boxes 6 disposed inside the file management rack 1 near the upper side of the placement plates 3, and a moisture-proof component 7 disposed inside the rear side of the file management rack 1, the dividing components 4 including a fixed component A square frame 41 is placed inside the file management shelf 1 near the upper side of the placement plate 3. Several sets of partition plates 42 are fixedly installed at the front end of the square frame 41. Two sets of sliding grooves 43 are opened on both sides of the several sets of partition plates 42. Two sets of U-shaped frames 44 are slidably installed between two adjacent sets of partition plates 42. A connecting plate 45 is fixedly installed on the rear side of the two sets of U-shaped frames 44. Square grooves 46 are opened at opposite ends of the front side of the two sets of U-shaped frames 44. Square spring pieces 47 are fixedly installed on the inner side of the two sets of square grooves 46. Positioning films 48 are fixedly installed at opposite ends of the front side of the U-shaped frames 44.

[0020] Several sets of partition plates 42 are evenly distributed horizontally on the upper side of the placement plate 3. The sliding grooves 43 on both sides of the several sets of partition plates 42 are staggered. The U-shaped frame 44 is slidably set between two adjacent sets of partition plates 42. The front side of the U-shaped frame 44 is inclined at the square groove 46 and is made of elastic deformable material. The positioning film 48 is made of rubber.

[0021] When the file box 6 is inserted between the two sets of U-shaped frames 44 and pushed inward, the two sets of U-shaped frames 44 slide along the corresponding sliding grooves 43, and the front tilt position of the U-shaped frame 44 and the positioning film 48 move accordingly, moving to the inner position of the two sets of partition plates 42. The positioning film 48 at the tilt position of the U-shaped frame 44 is pushed and clamped on both sides of the file box 6 by the partition plates 42, thereby stabilizing the file box 6 inserted between the two sets of partition plates 42 and reducing the shaking of the stored file box 6. At the same time, the partition plates 42 separate each set of file boxes 6, and the clamping of the two sets of positioning films 48 reduces contact with the partition plates 42, so that a certain gap is created between each set of file boxes 6, improving the overall ventilation.

[0022] The pushing component 5 includes a cavity sleeve 51 fixedly mounted at the center of the rear end of the connecting plate 45. A rotating shaft 52 is rotatably mounted inside the rear side of the cavity sleeve 51. A positioning rod 53 is fixedly mounted at the rear end of the rotating shaft 52. A damping spring 54 is damped between the rear end of the rotating shaft 52 and the inner wall of the cavity sleeve 51. A spring 55 is fixedly mounted on the outer side of the cavity sleeve 51 between the connecting plate 45 and the square frame 41. A fixing plate 56 is fixedly mounted on the rear inner wall of the square frame 41. The front end of the fixing plate 56 corresponds to the positioning rod. Two sets of support plates 57 are fixedly installed at position 53. A first guide cylinder 58 is fixedly installed on the front side of each set of support plates 57. A first triangular opening 59 is opened on the rear side of each set of first guide cylinders 58. Two sets of movable openings 510 are provided between the two sets of first triangular openings 59. A second guide cylinder 511 is fixedly installed at the front end of the fixed plate 56 near the two sets of support plates 57. Four sets of second triangular openings 512 are opened on the front side of the second guide cylinder 511. A round opening 513 is opened on the front side of the cavity sleeve 51 corresponding to the position of the positioning rod 53.

[0023] The cavity sleeve 51 is assembled. The positioning rod 53 is adapted to the round opening 513. The positioning rod 53 is set in a vertical position. The damping spring 54 is elastically pressed against the front end of the rotating shaft 52. The rotating shaft 52 and the cavity sleeve 51 are set to damped rotation. Two sets of movable openings 510 are adapted to the positioning rod 53. The tips of the upper and lower two sets of the four sets of second-order triangular openings 512 correspond to the positions of the two sets of movable openings 510. The tips of the other two sets of the four sets of second-order triangular openings 512 correspond to the inner positions of the two sets of first-order triangular openings 59.

[0024] When placing the file box 6, first insert the file box 6 into the two sets of U-shaped frames 44 between the two adjacent sets of partition plates 42. Push the positioning rod 53 backward through the round opening 513, compressing the spring 55. The vertically positioned positioning rod 53 passes between the two sets of movable openings 510 on the rear side. The positioning rod 53 moves backward and contacts the second triangular opening 512 on the upper and lower sides. The inclined surface of the second triangular opening 512 causes the positioning rod 53 and the rotating shaft 52 to rotate clockwise. When the bottom of the second triangular opening 512 generates resistance, the file box 6 is released. The compressed spring 55 pulls the positioning rod 53 towards the first guide cylinder 58 and contacts the inclined surface of the first triangular opening 59. The inclined plane guides the rotation to the bottom of the first triangular opening 59, so that the positioning rod 53 corresponds to the inclined surface of the second triangular opening 512 on the left and right sides. At the same time, the positioning rod 53 is restricted by the first triangular opening 59 in the first guide cylinder 58. The restricted positioning rod 53 positions the file box 6 in the partition plate 42. When the file box 6 is taken out, the required file box 6 is pushed. Similarly, the positioning rod 53 contacts and rotates with the second triangular opening 512 on both sides. With the push of the spring 55, it is guided by the two sets of first guide cylinders 58 to the positions of the two sets of movable openings 510, automatically releasing the positioning of the positioning rod 53. The spring 55 can then push the two sets of U-shaped frames 44 and the file box 6 outwards separately for easy access and use by the operator.

[0025] A shielding frame 71 is fixedly installed at the upper end of the file management shelf 1 near the rear side. An air-gathering pipe 72 is fixedly installed inside the shielding frame 71. A drying fan 73 is fixedly installed at the upper end of the air-gathering pipe 72. A main air pipe 74 is fixedly installed at the lower end of the air-gathering pipe 72. Three sets of branch air pipes 75 are fixedly installed on both sides of the main air pipe 74. A vent 76 is opened at the front of the six sets of branch air pipes 75. Several sets of air guide grooves 77 are opened at the upper end of the placement plate 3. Several sets of air guide plates 78 are fixedly installed inside the several sets of air guide grooves 77.

[0026] The main air pipe 74 is fixedly installed on the inner side of the inner partition 2, the six sets of branch pipes 75 are fixedly installed on the rear side of the six sets of placement plates 3, the air inlet 76 corresponds to the position of the air guide groove 77, and the air guide plate 78 is arc-shaped and set upward.

[0027] The drying fan 73 blows air from the main air duct 74 into the six sets of branch air ducts 75, and then through the air vents 76 into the several sets of air guide grooves 77 on the placement plate 3. The air guide grooves 77 ventilate the bottom of the file box 6. The air guide grooves 77 also suspend the bottom of the file box 6, creating an air circulation channel that prevents moisture from accumulating and keeps the air around the file box dry. In addition, the air guide plates 78 on the inside can guide the airflow upward and blow it into the gaps between each set of file boxes 6, thereby optimizing the drying and moisture-proofing of the file box 6.

[0028] Working principle: When placing the file box 6, first insert the file box 6 into the two sets of U-shaped frames 44 between the two sets of adjacent partition plates 42. Push the positioning rod 53 backward through the round opening 513, compressing the spring 55. The vertically positioned positioning rod 53 passes between the two sets of corresponding movable openings 510 on the rear side. The positioning rod 53 moves backward and contacts the second triangular opening 512 on the upper and lower sides. The inclined surface of the second triangular opening 512 causes the positioning rod 53 and the rotating shaft 52 to rotate clockwise. When the bottom of the second triangular opening 512 generates resistance, the file box 6 is released. The compressed spring 55 pulls the positioning rod 53 towards the first guide cylinder 58 and contacts the inclined surface of the first triangular opening 59. The inclined surface of the opening 59 guides the rotation to the bottom of the first triangular opening 59, so that the positioning rod 53 corresponds to the inclined surface of the second triangular opening 512 on the left and right sides. At the same time, the positioning rod 53 is restricted by the first triangular opening 59 in the first guide cylinder 58. The restricted positioning rod 53 positions the file box 6 in the partition plate 42. When the file box 6 is taken out, the required file box 6 is pushed. Similarly, the positioning rod 53 contacts and rotates with the second triangular opening 512 on both sides. With the push of the spring 55, it is guided by the two sets of first guide cylinders 58 to the positions of the two sets of movable openings 510, automatically releasing the positioning rod 53. The spring 55 can then push the two sets of U-shaped frames 44 and the file box 6 outwards separately for easy access by the operator. In use; additionally, when the file box 6 is inserted between the two sets of U-shaped frames 44 and pushed inward, the two sets of U-shaped frames 44 slide along the corresponding sliding grooves 43, and the front tilt position of the U-shaped frame 44 and the positioning film 48 move accordingly, moving to the inner position of the two sets of partition plates 42. The positioning film 48 at the tilt position of the U-shaped frame 44 is pushed and clamped on both sides of the file box 6 by the partition plates 42, thereby stabilizing the file box 6 inserted between the two sets of partition plates 42 and reducing the shaking of the stored file box 6. At the same time, the partition plates 42 separate each set of file boxes 6, and the clamping of the two sets of positioning films 48 reduces contact with the partition plates 42, so that a certain space is created between each set of file boxes 6. The gaps improve overall ventilation; secondly, the drying fan 73 blows air from the main air pipe 74 into the six sets of branch air pipes 75, and blows it into the several sets of air guide grooves 77 opened on the placement plate 3 through the air vents 76. The air guide grooves 77 are set to blow the air towards the lower side of the file box 6 for ventilation. The opening of the several sets of air guide grooves 77 makes the bottom of the file box 6 suspended, creating an air circulation channel, making it difficult for moisture to accumulate and keeping the air around the file box dry. In addition, several sets of air guide plates 78 are set on the inside to guide the airflow upward and blow it into the gaps between each set of file boxes 6, thereby optimizing the drying and moisture-proofing of the file box 6.

Their working principles are well-known technologies, and the appropriate model is selected according to actual use, so they will not be explained in detail.
