TECHNICAL FIELD

[0001] The utility model relates to the technical field of file compact shelving, and specifically relates to a damp-proof device of file compact shelving. BACKGROUND

[0002] Compact shelving generally refers to compact shelving, and the compact shelving is a new type of storage device suitable for storing books, archives, shelves, archival financial vouchers, and goods in government offices, enterprise and institution libraries, archives rooms, sample rooms, etc. Compared with traditional bookshelves, shelves, and archival shelves, the compact shelving has a large storage capacity, saves space, and has more traditional characteristics. The compact shelving mainly comprises a track, a base, a stand (a plate type), a shelf, a hanging plate, a side leaning plate, a back leaning plate, a top plate, a dustproof plate, a guard plate, a door plate, a transmission mechanism, an anti-toppling device, a shockproof device, a dustproof device, a rat-proof device, a brake, a buffer, a catalog card, and a transmission device, and a sealing device.

[0003] The paper archives in the file compact shelving have a risk of moisture for a long time of use, and the archives that are damp are prone to mold. People usually use other devices to prevent the compact shelving from being damp. The existing damp-proof method, such as the patent document with the announcement number CN212299706U, directly prevents the file cabinet from being damp through the hot air method. However, the compact cabinet involves multiple cabinet bodies, and only one hot air mechanism cannot dry and prevent the multiple cabinet bodies from being damp. Setting multiple hot air mechanisms has the problem of high cost. Therefore, a new damp-proof device of file compact shelving is proposed to facilitate the damp-proof of the multiple cabinet bodies of the compact shelving. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims to provide a damp-proof device of file compact shelving to solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme.

[0006] A moisture-proof device for a mobile filing cabinet includes fixed plates fixedly connected to the top surfaces of two cabinets of the mobile filing cabinet that are far apart from each other. A flexible spring tube is fixedly connected between the fixed plates. The flexible spring tube has an outer sleeve and an inner sleeve that are slidably fitted together. The inner sleeve and the outer sleeve cooperate to support the flexible spring tube. The flexible spring tube itself can expand and contract. The far ends of the inner sleeve and the outer sleeve are respectively fixedly connected to the corresponding fixed plates. The other end of the inner sleeve is inserted into the outer sleeve and slidably connected. Each cabinet of the mobile filing cabinet is fixedly connected to a rigid pipe that communicates with it. The rigid pipe is fixedly connected to the corresponding section of the flexible spring tube through a pipe joint and communicates with it. A connecting pipe is also connected to the flexible spring tube through a pipe joint. The connecting pipe is connected to the air outlet of a drying and moisture-proof box. The drying and moisture-proof box is fixedly connected to one of the cabinets of the mobile filing cabinet. A fan is fixedly installed inside the air inlet of the drying and moisture-proof box. An electric heating grid is fixedly connected inside the air outlet of the drying and moisture-proof box.

[0007] As a further embodiment of this utility model: the middle part of the drying and moisture-proof box is fixedly connected with an installation groove, and the part of the installation groove located inside the drying and moisture-proof box has a ventilation opening.

[0008] As a further embodiment of this utility model: a matching placement frame is slidably connected in the mounting groove, and a matching wire mesh frame is placed in the placement frame. The inner extension of the placement frame is larger than the ventilation opening, so that the wire mesh frame can be confined within the placement frame and the mounting groove to form a fixed placement effect. The wire mesh frame is filled with a desiccant.

[0009] As a further embodiment of this utility model: a hanging rod is fixedly connected to the top surface of the placement frame, the top end of the hanging rod extends out of the top of the mounting groove and is fixedly connected to a connecting plate, and electric telescopic rods are fixedly connected to the four corners of the bottom surface of the connecting plate, and the electric telescopic rods are fixedly connected to the side wall of the drying and moisture-proof box.

[0010] As a further improvement of this utility model: a plug seat is fixedly connected to the inner side of the top of the rigid tube, and a plug head adapted to the plug seat is provided below the plug head. A spring is provided below the plug head, and the bottom end of the spring abuts against the support mesh plate. The support mesh plate is fixedly connected to the inner wall of the rigid tube, and the spring is supported by the support mesh plate to keep the rigid tube unobstructed.

[0011] As a further embodiment of this utility model: the bottom surface of the plug is fixedly connected to a star-shaped column, the star-shaped column is slidably connected inside the rigid tube, the top end of the spring abuts against the bottom surface of the star-shaped column, and the bottom surface of the star-shaped column is provided with a groove for spring positioning. The star-shaped column can guide the movement of the plug and allow for ventilation.

[0012] As a further improvement of this utility model: the fan, electric heating grid and electric telescopic rod are all externally connected to a power source and a switch.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a fan to blow air and an electric heating grid to heat it. The hot air enters the spring hose through a connecting pipe, and then flows through a rigid pipe into each mobile shelving unit. The air inside the mobile shelving unit is discharged through the gaps in the unit itself, thus creating a hot air drying and moisture-proof effect. During use, the spring hose can extend and retract and is supported by an outer sleeve and an inner sleeve that can slide against each other, so that ventilation and connection can be maintained during the movement of the mobile shelving unit. This allows multiple mobile shelving units to be dried and moisturized simultaneously using a single drying and moisture-proof box.

[0015] 2. This utility model provides an installation groove on the drying and moisture-proof box, and places a desiccant in the installation groove, so that it can play the function of air intake and dehumidification during hot air drying and moisture-proofing, thereby further improving the hot air drying and moisture-proofing effect.

[0016] 3. In this utility model, the desiccant is placed inside the mesh frame, which is placed inside the placement frame. The placement frame is slidably connected to the mounting groove. The connecting plate and the hanging rod can be driven by an electric telescopic rod to raise and lower the placement frame in the mounting groove, thus facilitating the lifting and lowering of the mesh frame. This allows the mesh frame to be lowered during ventilation to dehumidify the air, and the mesh frame to be raised to the upper part of the mounting groove when there is no ventilation, thereby isolating the desiccant inside the mesh frame and preventing the desiccant from quickly becoming ineffective when not in use.

[0017] 4. In this utility model, the desiccant is placed inside the mesh frame, which is placed inside the placement frame. The placement frame is slidably connected to the installation groove. The electric telescopic rod drives the connecting plate and the hanging rod to raise and lower the placement frame in the installation groove, so that the placement frame can be completely lifted out of the installation groove, making it easy to remove the mesh frame and replace the desiccant.

[0018] 5. In this utility model, the rigid tube diverts the air inside the spring hose, and the spring presses the plug against the plug seat to form an elastic seal, thereby creating a pressurized ventilation effect. This avoids the effect of a large reduction in ventilation volume in the rigid tube far from the air inlet position of the connecting pipe, so that the thermal ventilation effect of each cabinet is similar.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figs. 1-2 In this embodiment of the utility model, a moisture-proof device for a mobile filing cabinet includes a fixed plate 1 fixedly connected to the top surface of two cabinets of the mobile filing cabinet that are far apart from each other. A spring hose 2 is fixedly connected between the fixed plates 1. The spring hose 2 has an outer sleeve 3 and an inner sleeve 4 that are slidably sleeved together. The inner sleeve 4 and the outer sleeve 3 cooperate to support the spring hose 2. The spring hose 2 itself can expand and contract. The ends of the inner sleeve 4 and the outer sleeve 3 that are far apart from each other are respectively fixedly connected to the corresponding fixed plates 1. The other end of the inner sleeve 4... The end is inserted into the outer sleeve 3 and slidably connected. Each cabinet of the filing mobile shelving is fixedly connected to a rigid pipe 5 that communicates with it. The rigid pipe 5 is fixedly connected to the corresponding section of the spring hose 2 through the pipe joint 6 and communicates with it. The spring hose 2 is also connected to a connecting pipe 7 through the pipe joint 6. The connecting pipe 7 is connected to the air outlet of the drying and moisture-proof box 9. The drying and moisture-proof box 9 is fixedly connected to one of the cabinets of the filing mobile shelving. A fan 10 is fixedly installed inside the air inlet of the drying and moisture-proof box 9. An electric heating grid 11 is fixedly connected inside the air outlet of the drying and moisture-proof box 9.

[0028] Air is blown by a fan 10 and heated by an electric heating grid 11. The hot air enters the spring hose 2 through the connecting pipe 7. The hot air entering the spring hose 2 is then distributed to each mobile shelving unit through the rigid pipe 5. The air inside the mobile shelving unit is discharged through the gaps in the mobile shelving unit itself, thus creating a hot air drying and moisture-proof effect. When in use, the spring hose 2 can be extended and retracted and is supported by the outer sleeve 3 and inner sleeve 4, which can slide against each other. This allows the mobile shelving unit to maintain a ventilated connection during movement, making it convenient to use a drying and moisture-proof box 9 to simultaneously apply hot air to the cabinets of multiple mobile shelving units.

[0029] Please see Figs. 2-5 A mounting groove 12 is fixedly connected through the middle of the drying and moisture-proof box 9, and a ventilation opening 13 is provided in the part of the mounting groove 12 located inside the drying and moisture-proof box 9.

[0030] A matching placement frame 14 is slidably connected inside the mounting slot 12. A matching mesh frame 15 is placed inside the placement frame 14. The inner extension of the placement frame 14 is larger than the vent 13, so that the mesh frame 15 can be confined within the placement frame 14 and the mounting slot 12, forming a fixed placement effect. The mesh frame 15 is filled with a desiccant 16.

[0031] A hanging rod 17 is fixedly connected to the top surface of the placement frame 14. The top end of the hanging rod 17 extends out of the top of the mounting groove 12 and is fixedly connected to a connecting plate 18. Electric telescopic rods 19 are fixedly connected to the four corners of the bottom surface of the connecting plate 18. The electric telescopic rods 19 are fixedly connected to the side wall of the drying and moisture-proof box 9.

[0032] An installation slot 12 is provided on the drying and moisture-proof box 9, and a desiccant 16 is placed in the installation slot 12, so that it can play the function of air intake and dehumidification during hot air drying and moisture-proofing, thereby further improving the hot air drying and moisture-proofing effect.

[0033] The desiccant 16 is placed inside the wire mesh frame 15, which is placed inside the placement frame 14. The placement frame 14 is slidably connected to the mounting groove 12. The connecting plate 18 and the hanging rod 17 can be driven by the electric telescopic rod 19 to raise and lower the placement frame 14 within the mounting groove 12, thus facilitating the lifting and lowering of the wire mesh frame 15. This allows the wire mesh frame 15 to be lowered during ventilation to dehumidify the air, and the wire mesh frame 15 to be raised to the upper part of the mounting groove 12 when there is no ventilation, thereby isolating the desiccant 16 inside the wire mesh frame 15 and preventing the desiccant 16 from quickly becoming ineffective when not in use.

[0034] The desiccant 16 is placed inside the wire mesh frame 15, which is placed inside the placement frame 14. The placement frame 14 is slidably connected to the mounting groove 12. The connecting plate 18 and the hanging rod 17 can be driven by the electric telescopic rod 19 to raise and lower the placement frame 14 in the mounting groove 12, so that the placement frame 14 can be completely lifted out of the mounting groove 12, making it easy to remove the wire mesh frame 15 and replace the desiccant 16.

[0035] Please see Fig. 6 A plug seat 20 is fixedly connected to the inner side of the top of the rigid tube 5. A plug head 21 that is adapted to the plug seat 20 is provided below the plug head 21. A spring 22 is provided below the plug head 21. The bottom end of the spring 22 abuts against the support mesh plate 23. The support mesh plate 23 is fixedly connected to the inner wall of the rigid tube 5. The support mesh plate 23 supports the spring 22 and keeps the rigid tube 5 unobstructed.

[0036] The bottom surface of the plug 21 is fixedly connected to the star-shaped column 8, which is slidably connected inside the rigid tube 5. The top of the spring 22 abuts against the bottom surface of the star-shaped column 8. The bottom surface of the star-shaped column 8 is provided with a groove for positioning the spring 22. The star-shaped column 8 can guide the movement of the plug 21 and allow ventilation.

[0037] The rigid pipe 5 diverts the air inside the spring hose 2, and the spring 22 presses the plug 21 against the plug seat 20 to form an elastic seal, thereby creating a pressurized ventilation effect. This avoids the effect of a large reduction in ventilation volume in the rigid pipe 5, which is far from the air intake position of the connecting pipe 7, and makes the thermal ventilation effect of each cabinet similar.

[0038] The fan 10, electric heating mesh 11 and electric telescopic rod 19 are all externally connected to power sources and switches.

[0039] The working principle of this utility model is as follows:

[0040] In use, air is blown by the fan 10 and heated by the electric heating grid 11. The hot air enters the spring hose 2 through the connecting pipe 7. The hot air entering the spring hose 2 is then distributed to each mobile shelving unit through the rigid pipe 5. The air inside the mobile shelving unit is discharged through the gaps in the mobile shelving unit itself, thus creating a hot air drying and moisture-proof effect. During use, the spring hose 2 can extend and retract and is supported by the outer sleeve 3 and inner sleeve 4, which can slide against each other. This allows the mobile shelving unit to maintain a ventilated connection during movement, making it convenient to use one drying and moisture-proof box 9 to simultaneously perform hot air moisture-proofing on multiple mobile shelving units. During hot air drying and moisture-proofing, the hot air is dried by the desiccant 16, which also serves as an intake dehumidifier, further improving the hot air drying and moisture-proofing effect. When the rigid tube 5 is diverted, the air pressure inside the spring hose 2 increases. The increased air pressure squeezes the plug 21, thereby compressing the spring 22 through the sliding cross column 8. This allows air to enter the rigid tube 5 through the gap between the plug 21 and the plug seat 20. The air then continues to pass through the cross column 8 and the support mesh plate 23, and finally enters the cabinet of the filing cabinet through the rigid tube 5, thus performing hot air drying and moisture prevention.

[0041] In use, the desiccant 16 is placed inside the mesh frame 15, which is placed inside the placement frame 14. The placement frame 14 is slidably connected to the mounting groove 12. The connecting plate 18 and the hanging rod 17 can be driven by the electric telescopic rod 19 to raise and lower the placement frame 14 within the mounting groove 12, thus facilitating the lifting and lowering of the mesh frame 15. This allows the mesh frame 15 to be lowered during ventilation to dehumidify the air, and the mesh frame 15 to be raised to the upper part of the mounting groove 12 when there is no ventilation, thereby isolating the desiccant 16 inside the mesh frame 15 and preventing the desiccant 16 from quickly becoming ineffective when not in use.

[0042] In use, the desiccant 16 is placed inside the mesh frame 15, which is placed inside the placement frame 14. The placement frame 14 is slidably connected to the mounting groove 12. The connecting plate 18 and the hanging rod 17 can be driven by the electric telescopic rod 19 to raise and lower the placement frame 14 in the mounting groove 12, so that the placement frame 14 can be completely lifted out of the mounting groove 12, making it easy to remove the mesh frame 15 and replace the desiccant 16.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
