[0003] For example, Chinese patent CN206808976U discloses a file rack comprising several shelves, each shelf mainly consisting of a base plate, a left upright plate, and a right upright plate; the shelves are stacked vertically; the top of the left and right upright plates of each shelf are respectively provided with left and right sliding grooves, and the left and right sides of the base plate are respectively provided with left and right sliding blocks, the positions of which correspond to the positions of the left and right sliding grooves at the top of the left and right upright plates of the shelf below; the left and right sliding blocks of the upper shelf are respectively embedded in the left and right sliding grooves at the top of the left and right upright plates of the lower shelf, and can slide relative to each other. In this utility model, the shelves can slide relative to each other, making it more convenient to pull out the corresponding shelf when searching for and retrieving files.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in its use, such as the inability to adjust the spacing between multiple trays, resulting in a waste of space due to the inability to dynamically adjust the spacing based on space utilization. Therefore, we propose a space-saving fixed file rack. Utility Model Content

[0006] The purpose of this invention is to provide a space-saving fixed file rack to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a space-saving fixed file rack, comprising:

[0008] The frame and the through groove are provided. The through groove is formed on the inner wall of the frame and is connected to the outside. Multiple sliding plates are slidably connected in the through groove, and one end of each sliding plate extends into the inner cavity of the frame. Multiple support plates are fixedly connected to one end of each sliding plate, and the support plates are located on the inner wall of the frame and slidably connected to the frame. Multiple sliding grooves are formed on one side of each sliding plate. Multiple first extrusion blocks and multiple second extrusion blocks are slidably connected in the multiple sliding grooves. A first threaded rod and a second threaded rod are threadedly connected to the first extrusion block and the second extrusion block, respectively.

[0009] Multiple first rotating slots are respectively opened in multiple sliding plates and connected to the outside. Multiple first connecting rods are rotatably connected in the multiple first rotating slots, and the two ends of the first connecting rods are respectively fixed to one end of a first threaded rod and a second threaded rod.

[0010] Multiple drive components are located within multiple slide plates and are used to drive the corresponding two first connecting rods to rotate.

[0011] Based on the above structure, the through groove, slide plate, and support plate ensure that multiple slide plates can slide along the through groove, respectively driving multiple support plates to slide. The first extrusion block, second extrusion block, and slide groove ensure that multiple first extrusion blocks and multiple second extrusion blocks can slide in multiple slide grooves respectively. The first rotating groove, first connecting rod, first threaded rod, and second threaded rod ensure that the first connecting rod can rotate in the first rotating groove. When the first connecting rod rotates, the two ends of the first connecting rod can drive the first threaded rod and the second threaded rod to rotate respectively, so that the first extrusion block and the second extrusion block are respectively acted by the threads of the first threaded rod and the second threaded rod, moving away from each other by the same distance or closer to each other by the same distance. The drive component ensures that the user can drive the corresponding two first connecting rods to rotate through the drive component.

[0012] In the above technical solution, the driving component further includes:

[0013] Two first gear slots are respectively opened on the inner wall of two first rotating slots. A first bevel gear and a second bevel gear are rotatably connected in the first gear slots, and the first bevel gear is fixed to the periphery of the first connecting rod.

[0014] Two second gear slots are formed inside the slide plate and are respectively connected to two first gear slots. A third bevel gear and a fourth bevel gear are rotatably connected in the second gear slots and mesh with each other. One end of the third bevel gear passes through the inner wall of the second gear slot and extends into the first gear slot to be fixed to the second bevel gear.

[0015] The second rotating groove is opened inside the slide plate and is connected to the two second gear grooves. A second connecting rod is rotatably connected inside the second rotating groove, and the two ends of the second connecting rod extend into the two second gear grooves respectively and are fixed to the two fourth bevel gears respectively.

[0016] The third rotating groove is formed inside the slide plate and is connected to the second rotating groove. A rotating rod is rotatably connected inside the third rotating groove, and one end of the rotating rod extends into the second rotating groove and is fixed to one end of the second connecting rod. The other end of the rotating rod passes through the inner wall of the third rotating groove and extends to the outside to be rotatably connected to the slide plate.

[0017] A fixing component is located on the periphery of the rotating rod and is used to fix the rotating rod.

[0018] In this technical solution, it is ensured that when the user adjusts the tray to a suitable position, the user can fix the tray in place.

[0019] In the above technical solution, the fixing component further includes:

[0020] A threaded groove is formed on the circumference of the rotating rod, and a threaded sleeve is threadedly connected to the threaded groove.

[0021] In this technical solution, it is ensured that the rotating rod will not be affected by external factors and will not rotate.

[0022] In the above technical solution, one end of the third bevel gear is rotatably connected to the first gear groove.

[0023] In this technical solution, it is ensured that when the third bevel gear rotates, one end of the third bevel gear can rotate normally within the first gear slot.

[0024] In the above technical solution, the second bevel gear and the third bevel gear are further coaxially connected.

[0025] In this technical solution, it is ensured that the second bevel gear and the third bevel gear can rotate stably.

[0026] In the above technical solution, furthermore, the two ends of the second connecting rod are rotatably connected to the two second gear slots respectively.

[0027] In this technical solution, it is ensured that when the second connecting rod rotates, both ends of the second connecting rod can rotate normally in the two second gear slots respectively.

[0028] In the above technical solution, one end of the rotating rod is rotatably connected to the second rotating groove.

[0029] In this technical solution, it is ensured that when the rotating rod rotates, one end of the rotating rod can rotate normally within the second rotating groove.

[0030] In the above technical solution, the threads on the first threaded rod and the second threaded rod have opposite directions of rotation, and the threads on the first threaded rod and the second threaded rod have the same pitch.

[0031] In this technical solution, it is ensured that when the first threaded rod and the second threaded rod rotate, the first extrusion block and the second extrusion block will be subjected to the opposite threads of the first threaded rod and the second threaded rod, respectively, and will move closer to each other by the same distance or further away from each other by the same distance.

[0032] The beneficial effects of this utility model are:

[0033] 1. This space-saving fixed filing rack, through its through slots, sliding plates, and trays, ensures that multiple sliding plates can slide along the through slots, driving multiple trays to slide. Through its first pressing block, second pressing block, and sliding groove, it ensures that multiple first pressing blocks and multiple second pressing blocks can slide within multiple sliding grooves. Through its first rotating groove, first connecting rod, first threaded rod, and second threaded rod, it ensures that the first connecting rod can rotate within the first rotating groove. When the first connecting rod rotates, its two ends can respectively drive the first and second threaded rods to rotate, causing the first and second pressing blocks to be acted upon by the threads of the first and second threaded rods, moving them away from or closer to each other by the same distance. Through its driving component, it ensures that the user can drive the corresponding two first connecting rods to rotate. This solves the problem of the filing rack's inability to adjust the spacing between multiple trays during use, resulting in wasted space due to the inability to dynamically adjust the spacing based on space utilization.

[0034] 2. This space-saving fixed file rack, through the setting of a third rotating groove and a rotating rod, ensures that the rotating rod can rotate within the third rotating groove. Through the setting of a fixing component, it ensures that the user can fix the rotating rod within the third rotating groove and prevent it from rotating due to external influences.

Multiple first extrusion blocks 5 and multiple second extrusion blocks 6 are slidably connected in the multiple sliding grooves 23 respectively. First threaded rods 9 and second threaded rods 10 are threadedly connected in the first extrusion blocks 5 and the second extrusion blocks 6 respectively.

[0051] Multiple first rotating grooves 7 are respectively opened in multiple sliding plates 3 and connected to the outside. Multiple first connecting rods 8 are rotatably connected in the multiple first rotating grooves 7, and the two ends of the first connecting rods 8 are respectively fixed to one end of the first threaded rod 9 and the second threaded rod 10.

[0052] Multiple drive components are located within multiple slide plates 3 and are used to drive the corresponding two first connecting rods 8 to rotate.

[0053] Example 2:

[0054] This embodiment provides a space-saving fixed file rack, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a driving component:

[0055] Two first gear slots 11 are respectively opened on the inner walls of two first rotating slots 7. A first bevel gear 12 and a second bevel gear 13 are rotatably connected in the first gear slots 11, and the first bevel gear 12 is fixed to the periphery of the first connecting rod 8.

[0056] Two second gear slots 14 are formed inside the slide plate 3 and are respectively connected to two first gear slots 11. A third bevel gear 15 and a fourth bevel gear 16 are rotatably connected inside the second gear slots 14 and mesh with each other. One end of the third bevel gear 15 passes through the inner wall of the second gear slot 14 and extends into the first gear slot 11 to be fixed to the second bevel gear 13.

[0057] The second rotating groove 17 is opened in the slide plate 3 and is connected to the two second gear grooves 14. The second rotating groove 17 is rotatably connected to the second connecting rod 18, and the two ends of the second connecting rod 18 extend into the two second gear grooves 14 respectively and are fixed to the two fourth bevel gears 16 respectively.

[0058] The third rotating groove 19 is opened in the slide plate 3 and is connected to the second rotating groove 17. A rotating rod 20 is rotatably connected in the third rotating groove 19. One end of the rotating rod 20 extends into the second rotating groove 17 and is fixed to one end of the second connecting rod 18. The other end of the rotating rod 20 passes through the inner wall of the third rotating groove 19 and extends to the outside to be rotatably connected to the slide plate 3.

[0059] A fixing component is located on the periphery of the rotating rod 20 and is used to fix the rotating rod 20.

[0060] In operation, the user manually rotates the rotating rod 20, causing one end of the rod 20 to rotate the second connecting rod 18 within the second rotating groove 17. This causes the second connecting rod 18 to rotate the two fourth bevel gears 16 within the two second gear grooves 14. When the two fourth bevel gears 16 rotate, they respectively drive the two third bevel gears 15 within the two second gear grooves 14, which in turn drive the two second bevel gears 13 within the two first gear grooves 11. The two second bevel gears 13 then drive the two first bevel gears 12 within the two first gear grooves 11. When the two first bevel gears 12 rotate, they respectively drive the two first bevel gears 13 within the two first gear grooves 11. The two first connecting rods 8 rotate within the two first rotating slots 7. When the first connecting rods 8 rotate, the two ends of the first connecting rods 8 will respectively drive the first threaded rod 9 and the second threaded rod 10 to rotate, so that the first pressing block 5 and the second pressing block 6 are respectively subjected to the opposite threads of the first threaded rod 9 and the second threaded rod 10, moving them closer to each other by the same distance or further away from each other by the same distance. When the two first pressing blocks 5 and the two second pressing blocks 6 are far apart to a position where they cannot move, the two first pressing blocks 5 and the two second pressing blocks 6 will be tightly pressed against the inner wall of the through slot 2, fixing the slide plate 3 in the through slot 2 and preventing it from moving. This ensures that when the user adjusts the tray 4 to a suitable position, the user can fix the tray 4 in place.

[0061] Example 3:

[0062] This embodiment provides a space-saving fixed file rack, which, in addition to the technical solutions of the above embodiments, also has the following technical features, the fixing components including:

[0063] The threaded groove 21 is formed on the circumference of the rotating rod 20, and a threaded sleeve 22 is threadedly connected to the threaded groove 21.

[0064] In use, the user rotates the threaded sleeve 22 by hand, causing the threaded sleeve 22 to move towards the frame 1 under the action of the threaded groove 21. This makes the threaded sleeve 22 tightly pressed against the frame 1, fixing the rotating rod 20 in the third rotating groove 19 so that it cannot rotate, ensuring that the rotating rod 20 will not be affected by external factors and will not rotate.

[0065] Example 4:

[0066] This embodiment provides a space-saving fixed file rack, which, in addition to the technical solution of the above embodiment, also has the following technical features: one end of the third bevel gear 15 is rotatably connected to the first gear groove 11.

[0073] Specifically, it is ensured that when the second connecting rod 18 rotates, both ends of the second connecting rod 18 can rotate normally within the two second gear slots 14 respectively.

[0074] Example 7:

[0075] This embodiment provides a space-saving fixed file rack, which, in addition to the technical solution of the above embodiment, also has the following technical features: one end of the rotating rod 20 is rotatably connected to the second rotating groove 17.

[0076] Specifically, it is ensured that when the rotating rod 20 rotates, one end of the rotating rod 20 can rotate normally within the second rotating groove 17.

[0079] Specifically, when the first threaded rod 9 and the second threaded rod 10 rotate, the first pressing block 5 and the second pressing block 6 will be subjected to the opposite threads of the first threaded rod 9 and the second threaded rod 10, respectively, and will move closer to each other by the same distance or further away from each other by the same distance.

[0080] In use, the user slides multiple trays 4 by hand, causing each tray 4 to drive multiple slide plates 3 to slide along the through groove 2. When the tray 4 moves to the appropriate position, the user rotates the rotating rod 20 by hand, causing one end of the rotating rod 20 to drive the second connecting rod 18 to rotate within the second rotating groove 17. This causes the second connecting rod 18 to drive two fourth bevel gears 16 to rotate within the two second gear grooves 14. When the two fourth bevel gears 16 rotate, they will drive two third bevel gears 15 to rotate within the two second gear grooves 14. This causes the two third bevel gears 15 to drive two second bevel gears 13 to rotate within the two first gear grooves 11. This causes the two second bevel gears 13 to drive two first bevel gears 12 to rotate within the two first gear grooves 11. When the two first bevel gears 12 rotate, they will drive two first connecting rods 8 to rotate within the two first rotating grooves 7. When the first connecting rod 8 rotates, the first connecting rod... The two ends of the connecting rod 8 will drive the first threaded rod 9 and the second threaded rod 10 to rotate respectively, so that the first pressing block 5 and the second pressing block 6 are subjected to the opposite threads of the first threaded rod 9 and the second threaded rod 10 respectively, moving them closer to each other by the same distance or further away from each other by the same distance. When the two first pressing blocks 5 and the two second pressing blocks 6 are far apart to a position where they cannot move, the two first pressing blocks 5 and the two second pressing blocks 6 will be tightly pressed against the inner wall of the through groove 2, fixing the slide plate 3 in the through groove 2 and preventing it from moving. This ensures that when the user adjusts the tray 4 to a suitable position, the user can fix the tray 4, allowing the user to adjust the spacing between multiple trays 4. Then, the user rotates the threaded sleeve 22 by hand, so that the threaded sleeve 22 is subjected to the thread of the threaded groove 21 and moves towards the frame 1, so that the threaded sleeve 22 is tightly pressed against the frame 1, fixing the rotating rod 20 in the third rotating groove 19 and preventing it from rotating, ensuring that the rotating rod 20 will not be affected by external factors and will not rotate.
