Detailed implementation mode

[0028] Next, a specific embodiment of the present invention will be elaborated in detail with reference to the accompanying drawings.

[0029] Refer to the attached Figures 1 - 10 , a movable filing cabinet based on convenient use, including an aluminum alloy bottom plate 101, a back plate 102 and two side plates 103 are fixedly connected on the bottom plate 101, a cabinet top 11 is slidably connected between the tops of the two side plates 103, the middle parts of the bottom plate 101, the back plate 102 and the cabinet top 11 all adopt a multi-stage slide rail nesting design, realizing axial expansion and contraction through high-precision linear guide rails, locking the tracks step by step when expanding, and realizing self-centering nesting when overlapping. The cabinet top 11, the bottom plate 101, the back plate 102 and the two side plates 103 together form a cabinet body 1 for placing documents. To facilitate the movement of the cabinet body 1, a plurality of universal wheels 10 are installed at the bottom of the bottom plate 101.

[0030] A partition component is arranged in the cabinet body 1 to divide the cabinet body 1 into a plurality of cabinet units convenient for placing project documents (hereinafter collectively referred to as: documents). Specifically: a plurality of telescopic frames 171 are fixedly connected between the two side plates 103, and the cabinet body 1 is divided into placing cavities 172 with the same unit storage capacity through the telescopic frames 171. A telescopic partition 17 is also fixedly connected between the side plates 103, so as to form a top cabinet cavity 170 in the cabinet body 1, and the top cabinet cavity 170 and the placing cavity 172 have different storage capacities.

[0031] Generally, the top cabinet cavity 170 and the placement cavity 172 can meet the placement requirements of a conventional number of documents. When the number of documents is large, the device can meet the placement requirements by adjusting the telescopic partition 17, the telescopic frame 171, and the bottom plate 101. Specifically: An electric push rod 16 is installed on the outer wall of the back plate 102. The telescopic end of the electric push rod 16 is fixedly connected to the movable end of the back plate 102 through a lug, aiming to drive the back plate 102 to extend through the movement of the telescopic end of the electric push rod 16, and the distance between the two side plates 103 is controlled to increase, thereby driving the cabinet top 11, the telescopic partition 17, and the telescopic frame 171 to all extend horizontally, achieving the effect of increasing the storage volume of the top cabinet cavity 170 and the placement cavity 172 to meet the placement requirements of a large number of documents.

[0032] Considering the placement requirements of documents of different sizes, the device is realized through hierarchical storage management. Specifically: The setting of the placement cavity 172 can meet the placement requirements of most conventional-sized documents, and the larger-sized documents are placed in the adjustable top cabinet cavity 170.

[0033] The adjustability of the top cabinet cavity 170 is realized by adjusting the height of the cabinet top 11. The cabinet top 11 is slidably connected to the top of the cabinet body 1. Sliding the cabinet top 11 upward causes the longitudinal height of the inner cavity of the top cabinet cavity 170 to extend, and the longitudinal height of the top cabinet cavity 170 increases, thereby meeting the placement requirements of larger-sized documents.

[0034] In the above, after the cabinet top 11 is adjusted to the appropriate height, it needs to be fixed. The device realizes this by setting a locking component on the cabinet top 11, specifically including adjusting members 12 fixedly connected to both ends of the cabinet top 11. The adjusting members 12 are L-shaped and follow the movement of the cabinet top 11. Locking members 14 are slidably connected to the ends of the adjusting members 12. A wedge-shaped block 141 is provided at the end of the locking member 14. Pressure springs 15 are compressed between the wedge-shaped block 141 and the adjusting members 12. Clamping members 13 are fixedly connected to the side plates 103. A plurality of pin holes 131 are formed in the clamping members 13. The wedge-shaped block 141 can be locked in the pin holes 131. The adjusting members 12, the locking members 14, the wedge-shaped block 141, the clamping members 13, and the pin holes 131 constitute a locking structure.

[0035] In the initial state, the wedge block 141 is locked in the pin hole 131 at the bottom of the clamp 13, and the cabinet top 11 is pulled upward. The adjusting member 12, the locking member 14 and the wedge block 141 are all subjected to an upward pulling force. The inclined surface of the wedge block 141 and the pin hole 131 are squeezed and moved. The wedge block 141 first retreats backward and then moves upward. The pressure spring 15 is deformed, and the height adjustment of the cabinet top 11 is completed. The wedge block 141 and the adjacent pin hole 131 are automatically engaged and locked again. Then the pressure spring 15 is reset and the wedge block 141 is locked in the pin hole 131, thereby completing the fixation of the adjusted height of the cabinet top 11, thereby meeting the placement requirements of larger files.

[0036] In order to improve the storage space utilization rate of the top cabinet cavity 170 and the placement cavity 172 in the present device and eliminate the invalid gaps caused by the loose arrangement of files, the following settings are made: a slide groove is opened on the side panel 103, and a telescopic member 110 is slidably connected to the slide groove through a connecting rod 113. The connecting rod 113 is fixedly connected to both sides of the telescopic member 110. The ends of the connecting rod 113 are rotatably connected to a ball 112, and the ball 112 directly contacts the slide groove on the side panel 103. A telescopic spring 111 is compressed between the slide groove of the side panel 103 and the telescopic member 110, so as to stabilize the telescopic member 110 in the slide groove of the side panel 103 by the elastic coefficient of the telescopic spring 111.

[0037] The telescopic part of the telescopic member 110 is fixedly connected to a sorting plate 18, and a force storage spring 19 is compressed between the sorting plate 18 and the side plate 103. The sorting plate 18 is built into the top cabinet cavity 170 and the placement cavity 172. The purpose is to dynamically compensate for the thickness change caused by the increase or decrease of files through an elastic mechanism composed of the telescopic member 110, the sorting plate 18, and the force storage spring 19, without manual adjustment, so that the files can be kept in a dense state, thereby improving the space utilization of the top cabinet cavity 170 and the placement cavity 172.

[0038] According to the background technology, when the files are closely arranged in the cabinet, the static friction between the files is too large. Manual extraction will cause the adjacent files to be displaced when a single file is extracted. Therefore, the present device abandons this manual extraction method and solves this problem with the following method: a slide plate 28 is fixedly connected to the cabinet top 11 through a fixed column 29, a slideway 281 is opened on the back of the slide plate 28, a sliding member 27 is slidably connected in the slideway 281, a telescopic column 26 is fixedly connected to the end of the sliding member 27, a telescopic portion of the telescopic column 26 is fixedly connected to a telescopic rod 25, and the telescopic end of the telescopic rod 25 is fixedly connected to a fixed rod 22, and the telescopic partition 17 is a telescopic double-layer plate structure, and its upper and lower plates A gap is reserved between the two plates to form a space cavity. A gap is also reserved between the telescopic partition 17 and the back plate 102 for non-contact assembly. The fixed rod 22 penetrates and slides in the space cavity between the upper and lower plates of the telescopic partition 17 and extends to the outside. The fixed rod 22, the telescopic rod 25, the telescopic column 26 and the sliding member 27 can constitute a movable push plate structure to achieve a directional push-out action of the file. The fixed rod 22, the telescopic rod 25, the telescopic column 26 and the sliding member 27 are pushed left and right and move synchronously, which means that the push plate structure first positions the target file, and then the fixed rod 22 is pulled forward, and the telescopic rod 25 and the telescopic column 26 are all controlled to move forward to achieve the effect of pushing the target file forward, so that the file is easy to take after it is exposed from the cabinet.

[0039] The above steps only realize the ejection of the file from the cabinet by mechanical linkage. However, in the process of manual removal, the problem of the displacement of adjacent files cannot be avoided. Based on this, the following settings are made: a connecting column 2 is fixedly connected to the side panel 103, and a limiting rod 221 is fixedly connected to the telescopic part of the connecting column 2. The ends of the limiting rod 221 are slidably connected to both sides of the fixed rod 22. A handle 21 is fixedly connected to the limiting rod 221 to prevent the displacement of adjacent files. The two limiting rods 221 are detachably connected at one end close to the fixed rod 22 by a pull rope 23 and a second pin 24, in order to facilitate the installation of the two limiting rods 221 and stabilize them on the fixed rod 22. A gap is reserved between the two limiting rods 221, in order to reserve a limited activity space for the target file to be ejected.

[0040] As the fixing rod 22 moves left and right, the connecting column 2, the limit rod 221 and the handle 21 move synchronously. After the fixing rod 22 locks the target file, the gap between the two limit rods 221 is exactly parallel to the file. The fixing rod 22 is pulled forward, and the fixing rod 22 slides forward at the bottom of the two limit rods 221. The telescopic rod 25 and the telescopic column 26 are both controlled to move forward, and the target file is ejected from the gap between the two limit rods 221. The adjacent file is restricted by the handle 21 and does not produce any associated displacement, thereby improving the efficiency of the device in extracting files.

[0041] In order to eliminate the invalid cavity caused by the loose arrangement of the files, the present device is implemented by setting the sorting plate 18, the force storage spring 19 and the telescopic member 110 in the above process. However, when the files stored in the top cabinet cavity 170 are saturated, due to the existence of the sorting plate 18, the friction between the adjacent files in the top cabinet cavity 170 increases and the files are closely arranged. When the files are extracted, there is a problem that the friction is too large and it is difficult to eject the files through the fixed rod 22. Therefore: the front end of the fixed rod 22 is fixedly connected to a rotating member 33, and the rear end of the fixed rod 22 is fixedly connected to a rotating ring 34 A first pulley 35 is fixedly connected to the back plate 102, a second pulley 36 is fixedly connected to the telescopic member 110, a positioning rod 311 is fixedly connected to the side of the back plate 102 away from the sorting plate 18, a winding rod 32 with a thin rope 3 wound around it is rotatably connected to the positioning rod 311, a torsion spring 31 is compressed between the winding rod 32 and the end of the positioning rod 311, the thin rope 3 passes through the rotating ring 34, bypasses the first pulley 35 and the second pulley 36, and the free end of the thin rope 3 is fixed on the sorting plate 18, and the thin rope 3 is fixed in length.

[0042] After the fixed rod 22 moves to locate the target file, it pulls the rotating member 33 forward to drive the fixed rod 22 to move forward. In order to facilitate the ejection of the file from the cabinet, the rotating member 33 is rotated, and the fixed rod 22 and the rotating ring 34 are controlled to rotate synchronously. The rotation of the rotating ring 34 makes the thin rope 3 bend and straighten, and then the thin rope 3 generates a pulling force, which acts on the sorting plate 18 through the transmission of the first pulley 35 and the second pulley 36, so that the sorting plate 18 retreats, the storage spring 19 deforms, and the telescopic end of the telescopic member 110 retreats. Synchronously, the winding rod 32 rotates, and the torsion spring 31 deforms, thereby The pulling force causes the sorting plate 18 to retreat a distance, thereby reducing the tight pressure on the documents, and then the rotating member 33 is pulled forward, driving the fixed rod 22, the telescopic rod 25, the telescopic column 26 and the sliding member 27 to move forward in a linked manner, forming a thrust to push the documents out, and the documents can be taken out from the gap between the two limit rods 221. After taking the documents, the rotating member 33 is rotated in the opposite direction, driving the rotating ring 34 of the fixed rod 22 to return to its original position, and the thin rope 3 is folded in the opposite direction to return to its original position, thereby canceling the pulling force on the thin rope 3, and under the action of the torsion spring 31 and the storage spring 19, the winding rod 32 and the sorting plate 18 are both returned to their original position.

[0043] The purpose of setting the sorting board 18 in this device is to tightly press the documents to make the force evenly distributed and eliminate the invalid gaps between the documents. According to experience, the sorting board 18 should tightly press the documents in the middle. However, when adjusting the height of the cabinet top 11 according to the size of the documents for adaptation, the sorting board 18 should synchronously adjust its height to adapt to the documents and then achieve tight pressing in the middle. According to common sense, if the displacement height of the cabinet top 11 is constantly twice the displacement distance of the sorting board 18, the sorting board 18 can constantly press the documents in the middle. Based on this, the following solution is made: On one side of the cabinet top 11 close to the sorting board 18, two rack groups are fixedly connected. The rack group includes a first rack 4 and a second rack 43 fixedly connected to the cabinet top 11. The first rack 4 and the second rack 43 are placed relatively parallel. Both rack groups are placed on both sides of the telescopic member 110. On both sides of the telescopic member 110, gears 41 are rotatably connected through fixing members 42. The gears 41 are meshed with the adjacent first rack 4 and second rack 43. The second rack 43, the first rack 4, the gear 41, and the fixing member 42 can form a distance reduction mechanism, meaning that the displacement distance of the cabinet top 11 makes the displacement distance of the sorting board 18 decrease proportionally through the distance reduction mechanism. When the cabinet top 11 moves up a certain distance, it drives the first rack 4 and the second rack 43 to move up the same distance, and then drives the gear 41 to rotate and move up by half the distance. Due to the existence of the connecting rod 113 and the ball 112, the telescopic member 110 can move up by half the distance in the chute of the side plate 103. The upward movement stroke of the sorting board 18 is half of the stroke of the cabinet top 11, resulting in the synchronous adjustment of the movement of the sorting board 18 to the movement of the cabinet top 11 to adapt to documents of different sizes and then always produce an effect of tightly pressing in the middle.

[0044] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
