Description

Technical Field

[0001] This utility model relates to the field of filing cabinet technology, and in particular to a storage cabinet. Background Technology

[0002] In offices, archives, and corporate document rooms, file storage cabinets are core equipment for storing paper documents and archives, and their performance directly affects the storage security and lifespan of the documents.

[0003] Currently available file storage cabinets still have shortcomings in actual use: poor moisture-proof performance. Most storage cabinets rely solely on the cabinet's own sealing or built-in desiccant for passive moisture protection. Passive moisture protection requires frequent replacement of the desiccant, which not only increases maintenance costs but also makes it difficult to quickly expel accumulated moisture in high humidity seasons (such as the rainy season), which can easily lead to mold growth on paper documents, paper aging and brittleness, and in severe cases, damage to important documents.

[0004] The aforementioned problems make existing file storage cabinets insufficient to meet the needs of long-term secure file storage, and there is an urgent need for a reliable moisture-proof file storage cabinet. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a moisture-proof file storage cabinet.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a moisture-proof file storage cabinet, comprising a cabinet body, a drive motor fixedly mounted on the top wall of the cabinet body, the output shaft of the drive motor penetrating vertically through the top wall of the cabinet body and extending into the interior of the cabinet body, and an exhaust fan blade coaxially fixedly connected to the output shaft via a coupling; a ventilation hole penetrating into the interior is provided on the back wall of the cabinet body near the bottom edge, and a sliding groove is vertically provided on the left and right sides of the ventilation hole on the back wall of the cabinet body; a moisture-proof sealing plate is slidably connected between the inner walls of the two sliding grooves, the moisture-proof sealing plate can slide up and down along the inner wall of the sliding groove to block or open the ventilation hole, and the outer surface of the moisture-proof sealing plate... The surface is fitted with a pin to limit its sliding position. The interior of the storage cabinet body is fixedly equipped with layered partitions along the horizontal direction. A cabinet door is hinged to one side wall of the storage cabinet body. An anti-collision component is provided on the side wall of the cabinet door facing the storage cabinet body. The anti-collision component includes a cylindrical sleeve, and the cylindrical sleeve and the cabinet door are detachably connected by a disassembly assembly. A sliding cylinder is slidably connected to the inner wall of the cylindrical sleeve along its axis. A buffer spring is fixedly connected to one end face of the sliding cylinder. A rod-through hole seat is fixedly connected to the end face of the cylindrical sleeve away from the sliding cylinder. The other end of the buffer spring is fixedly connected to the side of the rod-through hole seat facing the sliding cylinder, and an anti-collision guard plate is fixedly connected to the end face of the sliding cylinder away from the buffer spring.

[0007] Preferably, a rubber pad is fixedly connected to the inner wall of the cylindrical sleeve, and when the sliding cylinder slides along the inner wall of the cylindrical sleeve, its outer circumferential surface is in close contact with the surface of the rubber pad.

[0008] Preferably, a guide positioning rod is fixedly connected to one end face of the sliding cylinder near the buffer spring along the axial direction of the buffer spring. The guide positioning rod is coaxially disposed inside the buffer spring, and the guide positioning rod slides synchronously along the inner wall of the through-rod round hole seat when the sliding cylinder slides along the inner wall of the cylindrical sleeve.

[0009] Preferably, a support reinforcing rod is fixedly connected in the horizontal direction to the side wall of the anti-collision guard plate away from the sliding cylinder. The cross-section of the support reinforcing rod is trapezoidal and its larger end is fixedly connected to the wall of the anti-collision guard plate.

[0010] Preferably, the disassembly assembly includes a square card holder, which is vertically fixed to the side wall of the storage cabinet door facing the main body of the storage cabinet. A connecting block is fixedly connected to the end face of the cylindrical sleeve away from the anti-collision guard plate. The connecting block can be slidably inserted into the inner wall of the square card holder in the horizontal direction to realize the detachable connection between the cylindrical sleeve and the square card holder.

[0011] Preferably, a reinforcing plate is fixedly connected to the outer wall of the square card holder, and the side of the reinforcing plate away from the square card holder is fixedly connected to the wall of the cabinet door, and the reinforcing plate, the square card holder, and the cabinet door together form a triangular support structure.

[0012] Preferably, the top and bottom of the inner wall of the square card holder are fixedly connected with positioning blocks, and the top and bottom of the connecting blocks are respectively provided with positioning slots. When the connecting block is slid into the inner wall of the square card holder, the positioning block slides into the interior of the positioning slot in the vertical direction to limit the horizontal sway of the connecting block.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, the exhaust blades are driven by a motor to actively accelerate the airflow inside the cabinet, quickly expelling humid air. This, combined with the ventilation holes on the back of the cabinet, achieves efficient dehumidification. At the same time, the moisture-proof sealing plate in the sliding channel can close the ventilation holes when dehumidification is not needed, preventing external humid air from entering. The dustproof mesh on the inner wall of the ventilation holes also prevents dust from entering the cabinet with the air and contaminating the documents. This forms a triple moisture-proof mechanism of active exhaust dehumidification, passive sealing moisture-proofing, and dustproof protection. It can stably maintain a dry environment inside the cabinet without the need for frequent replacement of desiccant, significantly reducing the risk of mold and aging of paper documents and extending the service life of documents. It is especially suitable for document storage scenarios in high humidity areas or during the rainy season.

[0014] In this invention, the buffer spring in the anti-collision component can generate a reverse elastic force through compression when a collision occurs, directly weakening the impact energy. The rubber pad on the inner wall of the cylindrical sleeve can further buffer the sliding impact force of the sliding cylinder. Together with the guide positioning rod, it limits the buffer spring and the sliding cylinder, preventing lateral deformation of the spring and swaying of the cylinder, ensuring a stable buffering effect.

[0015] In this invention, the assembly and disassembly components achieve quick and detachable connection between the anti-collision components and the cabinet door through the sliding engagement of the square card holder and the connecting card block. Installation and disassembly can be completed without professional tools, which facilitates the daily inspection, replacement and maintenance of the anti-collision components and improves maintenance efficiency.

The output shaft of the drive motor 2 passes through the top wall of the cabinet body 1 vertically and extends into the interior of the cabinet body 1. The output shaft is coaxially connected to an exhaust vane 3 via a coupling. The exhaust vane 3 is located at the upper part of the interior of the cabinet body 1 to ensure effective ventilation of the interior space. A ventilation hole 5 is provided on the back wall of the cabinet body 1 near the bottom edge, extending into the interior. A dustproof mesh is provided on the inner wall of the ventilation hole 5 to prevent external dust from entering the cabinet. A sliding groove 6 is vertically provided on the left and right sides of the ventilation hole 5 on the back wall of the cabinet body 1. The inner walls of the two sliding grooves 6 are smoothed to reduce sliding resistance. A moisture-proof sealing plate 7 is slidably connected between the inner walls of the two sliding channels 6. The moisture-proof sealing plate 7 is made of plastic and has a moisture-proof film attached to its surface. The moisture-proof sealing plate 7 can slide up and down along the inner wall of the sliding channel 6 to block or open the ventilation hole 5. The outer surface of the moisture-proof sealing plate 7 is fitted with a pin to limit its sliding position. The pin is made of metal and can pass through the moisture-proof sealing plate 7 and be inserted into a pre-set hole in the side wall of the sliding channel 6 for fixation. A layered partition 4 is fixedly installed horizontally inside the main body of the storage cabinet 1. The layered partition 4 can be set to multiple layers according to the needs of document storage.

The edge of the cabinet door 8 is provided with a sealing strip to enhance the airtightness of the cabinet.

[0019] A collision protection component is installed on the side wall of the storage cabinet door 8 facing the main body 1. The collision protection component includes a cylindrical sleeve 10, which is made of metal tubing with a smooth inner wall. The cylindrical sleeve 10 and the storage cabinet door 8 are detachably connected via a disassembly assembly. A sliding cylinder 11 is slidably connected to the inner wall of the cylindrical sleeve 10 along its axis. The outer diameter of the sliding cylinder 11 is matched with the inner diameter of the cylindrical sleeve 10 to ensure sliding stability. A buffer spring 12 is fixedly connected to one end face of the sliding cylinder 11 by welding. The buffer spring 12 is a metal spring with good elastic recovery capability. A rod-through hole seat 13 is fixedly connected to the end face of the cylindrical sleeve 10 away from the sliding cylinder 11 by welding. The center hole of the rod-through hole seat 13 is collinear with the axis of the cylindrical sleeve 10. The other end of the buffer spring 12 is fixedly connected to the side of the through-rod round hole seat 13 facing the sliding cylinder 11 by welding. A crash guard 15 is bolted to the end face of the sliding cylinder 11 away from the buffer spring 12. The crash guard 15 is made of metal sheet with rounded corners to prevent sharp edges from damaging documents. A rubber pad is bonded to the inner circumference of the cylindrical sleeve 10. The rubber pad has a certain elasticity to provide cushioning. When the sliding cylinder 11 slides along the inner wall of the cylindrical sleeve 10, its outer circumferential surface is in close contact with the surface of the rubber pad. A guide positioning rod 14 is welded to the end face of the sliding cylinder 11 near the buffer spring 12 along the axis of the buffer spring 12. The guide positioning rod 14 is made of metal round rod with a diameter smaller than the inner diameter of the buffer spring 12. The guide positioning rod 14 is coaxially arranged inside the buffer spring 12, and when the sliding cylinder 11 slides along the inner wall of the cylindrical sleeve 10, the guide positioning rod 14 simultaneously slides along the inner wall of the through-rod round hole seat 13. A support reinforcing rod 16 is fixedly connected to the side wall of the anti-collision guard plate 15 away from the sliding cylinder 11 in the horizontal direction by welding. The support reinforcing rod 16 is made of metal rod, and its cross-section is trapezoidal. The larger end of the trapezoid is fixedly connected to the wall of the anti-collision guard plate 15 to enhance the connection strength.

[0020] The assembly includes a square bracket 9, made of bent metal sheet. The square bracket 9 is vertically fixed to the side wall of the storage cabinet door 8 facing the main body 1 of the storage cabinet, using welding or bolting. A connecting block 17 is welded to the end of the cylindrical sleeve 10 away from the anti-collision guard plate 15. The shape of the connecting block 17 matches the inner wall shape of the square bracket 9, and it can slide horizontally into the inner wall of the square bracket 9 to achieve a detachable connection between the cylindrical sleeve 10 and the square bracket 9. A reinforcing fixing plate 91, made of metal sheet, is welded to the outer wall of the square bracket 9. The side of the reinforcing fixing plate 91 away from the square bracket 9 is welded or bolted to the wall of the storage cabinet door 8. The reinforcing fixing plate 91, the square bracket 9, and the storage cabinet door 8 together form a triangular support structure to improve connection stability. The top and bottom of the inner wall of the square card holder 9 are fixedly connected by welding with positioning blocks 92. The positioning blocks 92 are made of metal blocks. The top and bottom of the connecting block 17 are respectively provided with positioning slots 18. The shape of the positioning slots 18 is adapted to the shape of the positioning blocks 92. When the connecting block 17 slides into the inner wall of the square card holder 9, the positioning blocks 92 slide into the interior of the positioning slots 18 in the vertical direction to limit the horizontal sway of the connecting block 17.

[0021] Working principle When storing documents in a moisture-proof manner, if dehumidification is required inside the main body 1 of the storage cabinet, start the drive motor 2. The output shaft of the drive motor 2 drives the exhaust blades 3 to rotate around the axis. During the rotation of the exhaust blades 3, the airflow inside the main body 1 of the storage cabinet will be accelerated, so that the humid air inside will be discharged from the ventilation hole 5. The dustproof mesh on the inner wall of the ventilation hole 5 can prevent external dust from entering the cabinet with the air in the opposite direction. When dehumidification is not required, slide the moisture-proof sealing plate 7 down along the sliding groove 6 until the moisture-proof sealing plate 7 completely covers the ventilation hole 5. At this time, insert the pin through the moisture-proof sealing plate 7 and into the hole on the side wall of the sliding groove 6 to fix the moisture-proof sealing plate 7, preventing external humid air from entering the main body 1 of the storage cabinet from the ventilation hole 5. At the same time, the sealing strip on the edge of the cabinet door 8 can further enhance the sealing of the cabinet and reduce the intrusion of moisture.

[0022] When the cabinet door 8 is hit by an external object, the anti-collision guard plate 15 will first come into contact with the object. The impact force generated by the collision will push the anti-collision guard plate 15 to move closer to the cabinet door 8. The anti-collision guard plate 15 will drive the sliding cylinder 11 to slide along the inner wall of the cylindrical sleeve 10. During the movement of the sliding cylinder 11, the buffer spring 12 will be compressed. The buffer spring 12 will generate a reverse elastic force due to compression. This elastic force can offset part of the impact force. At the same time, the rubber pad on the inner wall of the cylindrical sleeve 10 will rub against the outer circumference of the sliding cylinder 11 and generate a buffering effect, further weakening the impact force. The guide positioning rod 14 will slide synchronously with the sliding cylinder 11 along the inner wall of the through rod hole seat 13. This can prevent the buffer spring 12 from undergoing lateral deformation during compression and also prevent the sliding cylinder 11 from shaking when sliding. The support reinforcement rod 16 on the anti-collision guard plate 15 can enhance the structural strength of the anti-collision guard plate 15 and prevent the anti-collision guard plate 15 from deforming due to collision.

[0023] When installing the anti-collision component, align the connecting clip 17 with the opening of the square card seat 9 and slide it horizontally until the positioning clip 92 slides into the positioning slot 18. At this time, the connecting clip 17 is confined within the square card seat 9, thus fixing the anti-collision component to the cabinet door 8. The reinforcing fixing plate 91 on the outside of the square card seat 9 enhances the connection strength between the square card seat 9 and the cabinet door 8 through a triangular support structure, preventing the square card seat 9 from falling off under force. When it is necessary to disassemble the anti-collision component for maintenance, pull the anti-collision guard plate 15 away from the square card seat 9 to drive the connecting clip 17 out of the square card seat 9, thus completing the disassembly. The operation is convenient.
