Description

Technical Field

[0001] This utility model relates to the field of document cabinet technology, specifically to an assembled multi-layer document cabinet. Background Technology

[0002] Document cabinets are needed to store documents, providing protection and facilitating later retrieval and browsing.

[0003] Existing document cabinets are all fixed structures, and the overall internal space size and shape are fixed. When storing documents, most folders contain relatively few files, and the thickness of the folders themselves results in the folders being wider at one end, with an overall cross-section of a triangular structure. Since the folders need to be arranged in one direction for easy retrieval, when storing them in existing document cabinets with rectangular internal space, it is easy to cause an untidy phenomenon where the outer end is tightly packed and the inner end is empty, which is also a waste of storage space.

[0004] An existing patent (publication number: CN220024519U) discloses a prefabricated multi-layer document cabinet, which designs a file storage shell with a fan-shaped horizontal cross section. When placing documents, the wider end of the file shell faces outward. Because the file storage shell has a fan-shaped structure, multiple folders can be arranged in a fan-shaped distribution, which can save space for folders with a lot of triangular structures.

[0005] However, the above technical solutions still have certain drawbacks. When a user needs to access a document, the document needs to be rotated to the cabinet door position each time. After storing a certain number of documents, the weight of the entire device increases. Since the entire device needs to be rotated every time a document is accessed, it is inconvenient for the user and is time-consuming and labor-intensive. In addition, the documents in the device are stored in a relatively enclosed space with poor ventilation, which may cause the internal storage space to become damp. Therefore, a prefabricated multi-layer document cabinet is proposed. Utility Model Content

[0006] Therefore, the purpose of this utility model is to provide a prefabricated multi-layer document cabinet to solve the technical problems mentioned in the background.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated multi-layer document cabinet, comprising a lower support base body, a fixed base fixedly installed on the upper surface of the lower support base body, multiple rolling steel balls installed on the top of the fixed base, and the same supporting top ring installed on the multiple rolling steel balls, an annular groove corresponding to the multiple rolling steel balls and the supporting top ring being opened on the top of the fixed base, a base plate being snapped onto the top of the supporting top ring, a fixed column fixedly connected to the center of the upper surface of the base plate, a top plate fixedly connected to the top of the fixed column, several partitions fixedly installed between the top plate and the base plate, and one side of the several partitions being fixedly connected to the outer wall of the fixed column, a rotating column fixedly connected to the center of the top of the top of the top plate, a first gear fixedly connected to the top of the rotating column, several ventilation holes being opened on the top plate, a supporting column being connected to the center of the top of the first gear through a bearing, the top of the supporting column being fixedly connected to the bottom of another fixed base, the fixed base and the document storage mechanism being configured as a stacked structure, and a moving component being provided on the upper surface of the fixed base and outside the document storage mechanism.

[0008] As a preferred technical solution of the assembled multi-layer document cabinet of this utility model, the movable component includes a fixing ring fixedly installed on the upper surface of each group of fixed bases. The fixing ring is disposed on the outside of the partition. An arc-shaped fixing plate is fixedly connected to the top of the fixing ring. A notch is opened on one side of the arc-shaped fixing plate. A storage chamber is opened inside the arc-shaped fixing plate, and an arc-shaped movable plate is disposed inside the storage chamber.

[0009] As a preferred technical solution of the assembled multi-layer document cabinet of this utility model, each group of arc-shaped fixing plates is fixedly connected to a fixing plate on the outside, a motor is fixedly installed on the upper surface of the fixing plate, and a second gear is fixedly connected to the output end of the motor, the second gear meshing with the first gear.

[0010] As a preferred technical solution of the assembled multi-layer document cabinet of this utility model, the upper surface of the fixing ring is provided with an arc-shaped sliding groove, and the arc-shaped moving plate is slidably connected to the arc-shaped sliding groove.

[0011] As a preferred technical solution of the assembled multi-layer document cabinet of this utility model, one end of the outer side of the arc-shaped moving plate is connected to a rotating shaft through a bearing, and a rotating block is fixedly installed at the other end of the rotating shaft. A hook is fixedly connected to the outer side of the rotating block, and a retaining ring matching the hook is fixedly installed at one end of the outer side of the arc-shaped fixed plate.

[0012] As a preferred technical solution of the assembled multi-layer document cabinet of this utility model, a torsion spring is fixedly installed between the rotating block and the outer side of the arc-shaped moving plate, and the torsion spring is sleeved on the outer wall of the rotating shaft.

[0013] As a preferred technical solution of the assembled multi-layer document cabinet of this utility model, an upper support base body is fixedly installed on the top of the uppermost support column, and a fixing box is fixedly installed between the upper support base body and the lower support base body and on the outside of each group of motors.

[0014] In summary, the present invention has the following main advantages:

[0015] 1. This utility model starts the motor of the required storage layer, drives the second gear and the meshing first gear to rotate synchronously, thereby driving the rotating column to rotate, which in turn drives the document storage mechanism to rotate. Then, the document storage chamber to be stored or retrieved is rotated to the opening for storage and retrieval. By rotating the layers, there is no need to manually rotate the entire device, which saves time and effort and improves the practicality of the device.

[0016] 2. This utility model has multiple ventilation holes in the top plate, and each layer of document storage mechanism has a certain spacing, which greatly improves the ventilation of the device, so that the document storage cavity is always in a ventilated environment, avoiding internal moisture and thus preventing damage to the documents.

[0017] 3. The utility model utilizes a rotating block to disengage the hook fixed to it from the fixing ring, thereby releasing the limiting position between the arc-shaped moving plate and the arc-shaped fixed plate. At this point, the arc-shaped moving plate is pushed into the storage chamber within the arc-shaped fixed plate, opening a notch on one side of the arc-shaped fixed plate to facilitate document access. After the user has accessed the document, the arc-shaped moving plate is pushed back into its original position, and the hook and fixing ring provide initial limiting and fixing for the arc-shaped moving plate. Its limiting structure is simple and convenient for users. Simultaneously, by storing the arc-shaped moving plate in the storage chamber within the arc-shaped fixed plate, there is no need to open it outwards, making it more convenient to use in narrow and confined spaces and improving the usability of the device.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] A type of prefabricated multi-layer document cabinet, such as Figure 1-4As shown, the system includes a lower support body 100. A fixed base 110 is fixedly installed on the upper surface of the lower support body 100. Multiple rolling steel balls 120 are installed on the top of the fixed base 110, and a common support top ring 130 is installed on each of the multiple rolling steel balls 120. An annular groove corresponding to the multiple rolling steel balls 120 and the support top ring 130 is opened on the top of the fixed base 110. A base plate 140 is snapped onto the top of the support top ring 130. A fixed post 150 is fixedly connected to the center of the upper surface of the base plate 140. A top plate 160 is fixedly connected to the top of the fixed post 150. Several partitions 170 are fixedly installed between the top plate 160 and the base plate 140, and one side of each partition 170 is fixedly connected to the outer wall of the fixed post 150. The top center of the top plate 160 is fixedly connected to the base plate 140. A rotating column 180 is fixedly connected to the top of the rotating column 180, and a first gear 190 is fixedly connected to the top of the rotating column 180. Several ventilation holes are provided on the top plate 160. A support column 1940 is connected to the top center of the first gear 190 through a bearing. The top of the support column 1940 is fixedly connected to the bottom of another fixed base 110. The fixed base 110 and the document storage mechanism are arranged in a stacked structure. A moving component 200 is provided on the upper surface of the fixed base 110 and outside the document storage mechanism. A fixed plate 1910 is fixedly connected to the outer side of each set of arc-shaped fixed plates 220. A motor 1920 is fixedly installed on the upper surface of the fixed plate 1910. A second gear 1930 is fixedly connected to the output end of the motor 1920. The second gear 1930 meshes with the first gear 190.

[0030] When a user needs to access a document, the motor 1920 for the required storage layer is activated, driving the second gear 1930 to rotate. This, in turn, drives the first gear 190, which meshes with the second gear, to rotate. This, in turn, drives the rotating column 180, which is fixedly connected to the bottom of the first gear 190, to rotate as well. This, in turn, rotates the document storage mechanism, which includes a base plate 140, a fixed column 150, a top plate 160, and a partition 170. By designing a document storage cavity with a fan-shaped horizontal cross-section, documents are placed with the wider end facing outwards. Because of the fan-shaped structure, multiple folders can be arranged in a fan-shaped distribution, effectively saving space for folders with many triangular structures. The document storage chamber that needs to be stored or retrieved can be rotated to the notch for storage or retrieval. By rotating in layers, the entire device can be rotated manually without manual intervention, which saves time and effort and improves the practicality of the device. At the same time, the top plate 160 has multiple ventilation holes, and each layer of the document storage mechanism has a certain spacing, which greatly improves the ventilation of the device, ensuring that the document storage chamber is always in a ventilated environment and preventing the documents from getting damp and being damaged. The supporting top ring 130 has a groove, and the bottom of the base plate 140 has a matching locking block. The top of the fixed base 110 has an annular groove corresponding to the multiple rolling steel balls 120 and the supporting top ring 130, which further reduces the frictional resistance when the document storage mechanism rotates.

[0031] Please refer to this carefully. Figure 1 , Figure 4 , Figure 5 as well as Figure 6 As shown, the movable component 200 includes a fixing ring 210 fixedly installed on the upper surface of each fixed base 110. The fixing ring 210 is located on the outside of the partition 170. An arc-shaped fixing plate 220 is fixedly connected to the top of the fixing ring 210. A notch is opened on one side of the arc-shaped fixing plate 220. A storage chamber is opened inside the arc-shaped fixing plate 220, and an arc-shaped movable plate 230 is provided in the storage chamber. An arc-shaped sliding groove 211 is opened on the upper surface of the fixing ring 210. The arc-shaped movable plate 230 is slidably connected to the arc-shaped sliding groove 211. A rotating shaft is connected to one end of the outer side of the arc-shaped movable plate 230 through a bearing. A rotating block 250 is fixedly installed on the other end of the rotating shaft. A hook 260 is fixedly connected to the outer side of the rotating block 250. A retaining ring 240 matching the hook 260 is fixedly installed on one end of the outer side of the arc-shaped fixing plate 220. A torsion spring 270 is fixedly installed between the rotating block 250 and the outer side of the arc-shaped movable plate 230. The torsion spring 270 is sleeved on the outer wall of the rotating shaft.

[0032] When a user needs to open a document storage compartment of a certain layer, rotating the rotating block 250 causes the hook 260 fixed to it to disengage from the fixing ring 210. It is worth noting that the torsion spring 270 is initially in a wound state. When the rotating block 250 rotates and the hook 260 disengages from the fixing ring 210, the torsion spring is further wound, releasing the limiting position between the arc-shaped moving plate 230 and the arc-shaped fixed plate 220. At this time, the arc-shaped moving plate 230 is pushed into the storage chamber within the arc-shaped fixed plate 220, opening the notch on one side of the arc-shaped fixed plate 220, thus facilitating user access. When accessing documents, the curved sliding groove 211 guides the movement of the curved moving plate 230, making its movement more stable. After the user has finished accessing the document, the curved moving plate 230 is pushed back into place, and the hook 260 and the fixing ring 210 are used to initially limit and fix the curved moving plate 230. The limiting structure is simple and convenient for users. At the same time, the curved moving plate 230 is stored in the storage chamber inside the curved fixing plate 220 without having to open it outwards, which makes it more convenient to use in some narrow and confined spaces and improves the practicality of the device.

[0033] Please refer to this carefully. Figure 1 and Figure 4 As shown, the upper support column 1940 is fixedly installed with an upper support body 1950, and a fixing box 1960 is fixedly installed between the upper support body 1950 and the lower support body 100 and on the outside of each motor 1920.

[0034] The motor 1920 is hidden by setting up a mounting box 1960, and a control panel for the motor 1920 is set on the mounting box 1960 for easy operation of the device.

[0035] In use, when a user needs to access a document, they activate the motor 1920 for the layer to be accessed, which drives the second gear 1930 to rotate. This, in turn, drives the first gear 190, which meshes with the second gear, to rotate. This, in turn, drives the rotating column 180, which is fixedly connected to the bottom of the first gear 190, to rotate as well. This, in turn, drives the document storage mechanism to rotate, allowing the document storage chamber to be accessed or retrieved to be rotated to the opening. By rotating the layers, the entire device can be rotated manually, saving time and effort and improving its practicality. At the same time, the top plate 160 has multiple ventilation holes, and each layer of the document storage mechanism has a certain spacing, which greatly improves the ventilation of the device. This ensures that the document storage chamber is always in a ventilated environment, preventing the internal moisture from damaging the documents. Any parts of the device not mentioned herein are the same as or can be implemented using existing technologies.
