Description

Technical Field

[0001] The present invention relates to the technical field of filing cabinets, in particular to a filing cabinet. Background Art

[0002] Filing cabinets, which are cabinets used to store archival materials, are more traditional equipment for storing archives, usually referring to boxes with lids and cabinets with doors.

[0003] Existing file storage equipment, especially filing cabinets, mainly include the following common categories: drawer-type filing cabinets, door-type filing cabinets, and combined drawer and door filing cabinets. Combined filing cabinets are generally composed of drawers at the bottom, usually equipped with roller slides. The drawers are pulled outward to store and access hanging file folders or boxed files placed in them. The upper part is a double-door design. After opening the door, the file boxes or file folders placed on the shelves or racks can be directly accessed.

[0004] Filing cabinets are generally inconvenient to access files at high places. When accessing files, staff members of average height need to ask for help from tall colleagues or find stools, ladders and other stepping objects to assist in accessing, making the file access process cumbersome and time-consuming.

[0005] In addition, during the process of accessing files on high floors of the filing cabinet, since the cabinet structure is not equipped with a dedicated temporary storage platform, users must hold on to supports with one hand to maintain balance when climbing ladders or stepping on objects. After taking the files with the other hand, they are often forced to adopt unstable postures such as clamping under the armpits and pressing against the chest to temporarily fix the files. Continuing to operate in this state can easily cause the user to step on air and fall, increase the probability of the cabinet overturning and the files falling.

[0006] In addition, in the storage process of existing filing cabinets, when users place thinner or insufficient file boxes into the filing cabinet, due to the lack of effective lateral limiting devices, the file boxes can only rely on their own gravity to remain upright, which can easily lead to the formation of suspended areas between the file boxes and the front and rear edges of the shelves. Slight vibrations or pulling of adjacent files can easily cause domino-style tipping. The tilted file boxes in the filing cabinet will be squeezed for a long time, causing the file covers to wear and the bindings to deform.

The contents mentioned in the following embodiments are all based on the accompanying drawings.

[0025] Various exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0026] The present invention is a file management cabinet. Existing file cabinets are generally inconvenient to access files at high places when in use. When accessing files, it is necessary to ask for help from tall colleagues or find stools, ladders and other stepping objects to assist in access, making the file access process cumbersome and time-consuming.

[0027] When accessing files on high floors of filing cabinets, users must hold onto supports with one hand to maintain balance when climbing ladders or stepping on objects. After taking files with the other hand, they are often forced to adopt unstable postures such as clamping under the armpits and pressing against the chest to temporarily fix the files. Continuing to operate in this state can easily cause the user to step on empty space and fall, increasing the probability of the cabinet overturning and files falling.

[0028] As an embodiment, the present invention includes a cabinet body 1, which includes a main storage chamber 2, an auxiliary storage chamber 3 and a side storage chamber 4.

The ladder-type platform 14 slides out along the shape of the sliding rod 11, and rotates at the turning point of the sliding rod 11 when the ladder-type platform 14 moves out. , so that the angle of the ladder-type step 14 can be adjusted after sliding out, and a movable pushing block 19 is provided on the other side of the sliding sleeve 12. The pushing block 19 is L-shaped, and a rail-shaped guide rod 20 is fixedly connected to one side of the inner wall of the side storage chamber 4 close to the partition frame 7. The rail-shaped guide rod 20 is divided into three parts: an intermediate end 201, a guide end 202 and an entry end 203. The intermediate end 201 is close to the inner wall of the side storage chamber 4, and the guide end 202 is located on both sides of the intermediate end 201. The two guide ends 202 are close to the partition frame 7, and the entry end 203 is located on both sides of the two guide ends 202. The entry end 203 gradually approaches the inner wall of the side storage chamber 4 from the position where the guide end 202 is connected, and is fixed to the inner wall of the side storage chamber 4. The bottom of the pushing block 19 contacts the rail-shaped guide rod 20 and slides in accordance with the shape of the rail-shaped guide rod 20, and the pushing block 19 cooperates with the rail-shaped guide rod 20; A working groove 34 is provided on the front of the cabinet 1. The working groove 34 is square. The working groove 34 is provided on the front of the cabinet 1 between the main storage chamber 2 and the side storage chamber 4, so that the support plate 35 can slide out in the working groove 34.

The partition 9 cooperates with the inner wall of the side storage chamber 4 to form a space. The sliding sleeve 12 is fixedly connected to a support block 15 on one side close to the rail-shaped guide rod 20, and a slide groove 16 is provided on the other side of the support block 15. The slide groove 16 is square, and a slider 17 is slidably connected to the slide groove 16. The slider 17 is square, so that the slider 17 can slide freely in the slide groove 16, and the slider 17 is limited so that the slider 17 can slide along the shape of the slide groove 16. A first spring 18 is provided between the slider 17 and the inner wall of the slide groove 16, and the push block 19 is fixedly connected to one side of the slider 17.

[0031] In this embodiment, when the ladder-type step 14 is pulled, the sliding sleeve 12 slides on the sliding rod 11 to drive the support block 15 on one side to move, thereby driving the pushing block 19 to move in accordance with the shape of the rail-shaped guide rod 20. When the movement begins, the pushing block 19 fits the entry end 203, and through the inclined entry end 203, the pushing block 19 is subjected to the extrusion force and gradually approaches the support block 15. The slider 17 inside the chute 16 is gradually pushed into the chute 16 by the pushing block 19, squeezing the spring, causing the spring to generate a reverse force. When the pulling is continued, the pushing block 19 fits the rail-shaped guide rod 20 and enters the guide end 202. At this time, the pushing block 19 pushes the slider 17 to reach the maximum value entering the slide groove 16. When the pulling is continued, the pushing block 19 enters the middle end 201. At this time, the pushing block 19 is separated from the guide end 202, so that the slider 17 is only subjected to the reverse force generated by the first spring 18 inside the slide groove 16, so that the pushing block 19 is close to the middle end 201 and fits the middle end 201, so that the pushing block 19 located at the middle end 201 can apply pressure to the folding arm push plate 31 on one side.

The plurality of insertion grooves 43 are evenly arranged in a straight line on the fixed plate 42, and a positioning frame 44 is sleeved on the fixed plate 42, and the bottom of the positioning frame 44 is fixedly connected to the connecting base 50, and the inserting plate 51 is fixedly connected to the bottom of the connecting base 50, and the bottom of the inner wall of the positioning frame 44 is fixedly connected to the inserting block 49, and the inserting block 49 is cylindrical , thereby cooperating with the insertion slot 43 to limit and fix the positioning frame 44, the insertion block 49 cooperates with the insertion slot 43 on the fixed plate 42, and a pushing plate 45 is slidably connected in the positioning frame 44. The pushing plate 45 is square, and both sides are fitted on both sides of the inner wall of the positioning frame 44 for sliding. A second spring 46 is provided between the pushing plate 45 and the top of the inner wall of the positioning frame 44, and four fixing slots 47 are opened at the bottom of the pushing plate 45. The four fixing slots 47 are evenly distributed at the bottom of the pushing plate 45, and guide wheels 48 are rotatably connected in the four fixing slots 47. The four guide wheels 48 are in contact with the top of the fixed plate 42. Multiple slide rails 5 are provided on both sides of the inner wall of the auxiliary storage chamber 3, and drawers 6 are slidably connected to the multiple slide rails 5. A long roll storage box 10 is placed in the side storage chamber 4, and the long roll storage box 10 is located on one side of the partition frame 7 and the placement plate 8.

[0037] In this embodiment, the inserted files are limited by the inserting plate 51 to prevent the placed files from tilting. When the inserting plate 51 needs to be moved, the inserting plate 51 is pulled to drive the positioning frame 44 to move downward, thereby supporting the pushing plate 45 and squeezing the second spring 46 between the pushing plate 45 and the positioning frame 44, so that the second spring 46 generates a reverse force, which generates an upward thrust on the positioning frame 44. In the process of the positioning frame 44 being continuously pulled down, the insertion block 49 at the bottom of the inner wall of the positioning frame 44 moves out of the insertion groove 43. After the movement, the user can push the positioning frame 44 to slide on the fixed plate 42, thereby driving the bottom inserting plate 51 to move, so as to accommodate different numbers of files. When the files are used, when pushing the positioning frame 44, the guide wheel 48 at the bottom of the pushing plate 45 is rotated in contact with the top of the fixed plate 42, so that the positioning frame 44 can move smoothly. After moving to the appropriate position, by loosening the positioning frame 44, the positioning frame 44 is only subjected to the reverse force of the second spring 46, thereby pushing the positioning frame 44 to move upward, driving the insertion block 49 at the bottom of the inner wall of the positioning frame 44 to enter the insertion groove 43 on the fixed plate 42, thereby limiting and fixing the positioning frame 44 and fixing the bottom plug-in plate 51. When needed, the staff can pull the drawer 6 to slide on the slide rail 5 to place the file documents, and use the long roll storage box 10 to facilitate the placement of longer tools.

[0038] Working principle of the present invention: When in use, the cabinet door of the main storage chamber 2 can be opened to place files on the support plate 40. For accessing files at high places, the user can open the cabinet door of the side storage chamber 4 and pull out the ladder-type platform 14 in the side storage chamber 4. When pulling it out, the sliding sleeve 12 slides on the sliding rod 11, thereby limiting the trajectory of the ladder-type platform 14 when it is pulled out, and the ladder-type platform 14 is supported by the support seat 296 at the bottom, so that it is convenient for the user to step on it for access operations.

[0039] When pulling out, when the sliding sleeve 12 slides on the sliding rod 11, the pushing block 19 on one side is driven to push the folding arm push plate 31, so that the folding arm push plate 31 slides on the limit rod 30, and the connecting block 33 at the top of the limit rod 30 pushes the support plate 35 to slide out in the working groove 34, so as to facilitate the staff to place the files when accessing the files at high places. When the support plate 35 slides and is pulled out in the working groove 34, the two extension plates 38 on the support plate 35 are driven to rotate and expand, thereby increasing the placement area at the top of the support plate 35.

[0040] When placing files on the support plate 40, the baffle can be supported and limited by the plug plate 51. When placing files, the positioning frame 44 can be pulled and pushed to slide on the fixed plate 42 to adjust the position of the bottom plug plate 51 to cooperate with the user's operation.

[0041] The present invention has the following technical effects.

[0042] 1. The present invention utilizes the slide bar 11, the slide sleeve 12, the ladder-type platform 14, and the support assembly 29 to facilitate users to step on files at a high position in the filing cabinet when they need to access them, thereby increasing the operating height and assisting in accessing files. The limit rod 30, the folding arm push plate 31, the working groove 34, and the support plate 35 enable the support plate 35 to be extended when the staff pulls the ladder-type platform 14 for use, thereby assisting the staff in temporarily placing files when accessing files at a high position.

[0043] 2. The present invention utilizes the storage slot 36, the pin seat 37, and the extension plate 38. When the support plate 35 slides out in the working slot 34, the extension plate 38 is driven to rotate and expand, thereby expanding the receiving area on the top of the support plate 35, making it easier for users to place more files. The long roll storage box 10 is provided to facilitate users to place longer documents or tools used for accessing files.

[0044] 3. The present invention facilitates the extraction of air from the cabinet for dehumidification through the exhaust fan 22, placement frame 23, desiccant 24 and cover 26, thereby protecting the stored files and avoiding corrosion and damage to the files due to excessive humidity in the cabinet, while facilitating the replacement of the desiccant 24.

[0045] 4. The present invention provides lateral support and position limiting for stored files through the insert plate 51, thereby preventing the files from tilting. The position of the insert plate 51 is easily adjusted through the fixed plate 42, positioning frame 44, second spring 46 and insert block 49, thereby providing corresponding auxiliary support according to the different storage positions of the files.
