Description

Technical Field

[0001] This utility model relates to the field of filing cabinet technology, specifically, to a filing management cabinet that facilitates quick retrieval of documents. Background Technology

[0002] High-density filing cabinets, also known as file storage systems, are storage devices specifically designed to store large amounts of documents, archives, or data. With the modernization of society, especially in industries such as business, education, and healthcare, the volume of archival data is increasing daily. Traditional archival storage methods (such as ordinary filing cabinets) are no longer sufficient to meet the requirements of efficient management due to limited space and inconvenient access.

[0003] The emergence of high-density filing cabinets was precisely to address this challenge. By optimizing space design, they significantly increase storage density. Traditional filing cabinets are typically fixed, while high-density filing cabinets employ a movable design. Using a track or caster system, multiple units of the cabinet can slide back and forth along a single track, thus saving considerable space. Their structure can be adjusted as needed, and can even be expanded on demand, offering high flexibility and adaptability.

[0004] However, most common high-density filing cabinets on the market lack a locking mechanism for individual cabinets, or the locking mechanism is too complex. When an individual cabinet is impacted by an external force, it will slide on the track due to the lack of a locking mechanism, causing adjacent cabinets to collide and documents to fall. Utility Model Content

[0005] The purpose of this utility model is to provide a file management cabinet that facilitates quick retrieval of files, and to solve the problem that existing dense file cabinets lack locking mechanisms, causing abnormal movement of the cabinet body after being impacted by external forces.

[0006] This utility model is achieved through the following technical solution: a file management cabinet for easy and quick retrieval, comprising a slide rail and multiple individual cabinets mounted on the slide rail. Each individual cabinet is provided with a drive unit for driving the individual cabinet to slide on the slide rail. The drive unit includes a crank handle, a drive shaft, a first toothed belt, a transmission shaft, a roller, and a second toothed belt. The drive shaft is mounted on the crank handle, the first toothed belt is sleeved on the drive shaft and the transmission shaft, and the second toothed belt is sleeved on the transmission shaft and the roller. The transmission shaft and the roller are both rotatably connected to the individual cabinet. The drive unit also includes a locking unit for locking the individual cabinet to prevent it from moving.

[0007] To better realize this utility model, the locking unit further includes a mating disc, a locking ring, and a control lever. The mating disc is mounted on the drive shaft, the locking ring is slidably connected to the single cabinet, and the control lever is inserted into the drive shaft. The control lever is connected to the locking ring, and the locking ring and the mating disc form a cooperation.

[0008] To better realize this utility model, it further includes a limit retaining group, which is used to limit the relative position of the control lever and the drive shaft to ensure that the locking ring is stably engaged or disengaged from the fitting plate.

[0009] To better realize this utility model, the limiting and retaining assembly further includes a fitting block and a spring. The fitting blocks are respectively installed at both ends of the spring. The fitting blocks are slidably connected to the control lever in a radial direction. The drive shaft is provided with two limiting ring grooves. The fitting blocks are embedded in the limiting ring grooves to limit the control lever.

[0010] To better realize this utility model, the end of the control lever is provided with a pull ring, the inner diameter of which is 30mm.

[0011] To better realize this utility model, the diameter of the pulley on the drive shaft is smaller than the diameter of the corresponding pulley on the transmission shaft, that is, the transmission ratio from the drive shaft to the transmission shaft is greater than 1.

[0012] To better realize this utility model, the single cabinet further includes a cabinet body, a shell, and a base. The base is slidably connected to the slide rail, the cabinet body is mounted on the base, the shell is mounted on the cabinet body, the drive shaft is rotatably connected to the shell, and the locking ring is slidably connected to the cabinet body.

[0013] To better realize this utility model, the base is further provided with a slider, the slider is embedded in the slide rail, and the slide rail is embedded in the base.

[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0015] (1) By setting a locking unit, the individual cabinet is locked. When the filing cabinet is idle, if the individual cabinet is hit by an external force or the crank is accidentally turned, the individual cabinet will not slide on the slide rail due to the action of the locking unit, thereby improving the stability of the entire filing cabinet.

[0016] (2) By setting a limit retaining group, this utility model makes the position of the operating rod stable, that is, improves the locking stability of the locking unit to the cabinet;

[0017] (3) By setting the control lever in the crank handle, the locking operation is more convenient. After each document is retrieved, the crank handle is driven to reset the individual cabinet. The locking operation can be completed by simply pulling the control lever. Unlocking is also only required by pressing. The structure is simple and easy to promote and use.

Detailed Implementation

[0025] 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.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Example 1:

[0028] This embodiment provides a file management cabinet that facilitates quick retrieval of documents, specifically as follows: Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, the device includes a slide rail 104 and multiple individual cabinets mounted on the slide rail 104. Each individual cabinet is equipped with a drive unit for sliding on the slide rail 104. The drive unit includes a crank handle 201, a drive shaft 208, a first toothed belt 203, a transmission shaft 202, a roller 204, and a second toothed belt 205. The drive shaft 208 is fixedly connected to the crank handle 201. The first toothed belt 203 is sleeved on the drive shaft 208 and the transmission shaft 202. The second toothed belt 205 is sleeved on the transmission shaft 202 and the roller 204. The transmission shaft 202 and the roller 204 are both rotatably connected to the individual cabinets. The drive unit also includes a locking unit for locking the individual cabinets to prevent them from moving.

[0029] When a document needs to be retrieved, the corresponding numbered individual cabinet is located. The cabinet is then moved using the drive mechanism, or adjacent individual cabinets are moved aside, separating the target cabinet from its neighbors. Specifically, the operator moves the crank handle 201, which drives the drive shaft 208. The drive shaft 208, through the first toothed belt 203, drives the transmission shaft 202 to rotate. The transmission shaft 202, through the second toothed belt 205, drives the roller 204 to rotate, thus moving the individual cabinet. The operator can then enter the gap to retrieve the required document. After retrieval, the individual cabinet is locked using the locking unit. When the filing cabinet is not in use, if an external force impacts the individual cabinet or the crank handle 201 is accidentally moved, the locking unit will prevent the individual cabinet from sliding on the slide rail 104. In extreme cases, such as during an earthquake, the filing cabinet will not easily slide, thus improving the overall stability of the filing cabinet.

[0030] Example 2:

[0031] This embodiment further expands the locking unit based on the above embodiment, specifically as follows: Figures 4-6 As shown, the locking unit includes a mating disc 207, a locking ring 206, and a control lever 209. The mating disc 207 is fixedly connected to the drive shaft 208, the locking ring 206 is slidably connected to the single cabinet, and the control lever 209 is inserted into the drive shaft 208. The control lever 209 is connected to the locking ring 206, and the locking ring 206 and the mating disc 207 form a cooperation.

[0032] When it is necessary to unlock the individual cabinet, press the operating lever 209 on the drive shaft 208. At this time, the operating lever 209 drives the locking ring 206 to slide on the individual cabinet until the locking ring 206 disengages from the mating plate 207. At this time, the locking ring 206 no longer limits the mating plate 207, and the crank 201 can rotate freely. When it is necessary to lock the individual cabinet, pull the operating lever 209. At this time, the operating lever 209 drives the locking ring 206 to engage with the mating plate 207. Since the locking ring 206 will not rotate, the mating plate 207 will also not rotate. This prevents the drive shaft 208 and the crank 201 from rotating, thus locking the crank 201 and preventing it from being accidentally moved. Since the drive shaft 208 cannot rotate, the first toothed belt 203, the transmission shaft 202, and the second toothed belt 205 will also be unable to rotate, thus locking the roller 204 and preventing the individual cabinet from moving accidentally.

[0033] Furthermore, it also includes a limiting and retaining assembly, which is used to limit the relative position of the control lever 209 and the drive shaft 208, ensuring that the locking ring 206 is stably engaged or disengaged from the fitting disc 207. The limiting and retaining assembly includes a fitting block 211 and a spring 212. The fitting blocks 211 are respectively installed at both ends of the spring 212. The fitting blocks 211 are slidably connected to the control lever 209 in a radial direction. The drive shaft 208 is provided with two limiting ring grooves 213. The fitting blocks 211 are embedded in the limiting ring grooves 213 to limit the control lever 209.

[0034] When the lever 209 is pulled or pressed, the locking block 211 is first forced back into the lever 209. At this time, the spring 212 is compressed, and then the lever 209 begins to move axially until the locking block 211 moves to another limiting ring groove 213. At this time, the locking block 211 is ejected under the action of the spring 212, so that the locking block 211 is embedded in the limiting ring groove 213. The operator will also hear a "ding" sound produced by the locking block 211 hitting the limiting ring groove 213. Then the lever 209 stops moving. Since the locking ring 206 locks the locking disc 207 with radial force, the lever 209 is not subjected to axial force. After the spring 212 pushes the locking block 211 into the limiting ring groove 213, the position of the lever 209 will be quite stable without the operator applying external force.

[0035] Furthermore, a pull ring 210 is provided at the end of the control lever 209, and the inner diameter of the pull ring 210 is 30mm. When the operator pulls the control lever 209, they can insert their fingers into the pull ring 210, which improves the ease of pulling and pressing the control lever 209.

[0036] Furthermore, the diameter of the pulley on the drive shaft 208 is smaller than the diameter of the corresponding pulley on the transmission shaft 202, meaning the transmission ratio from the drive shaft 208 to the transmission shaft 202 is greater than 1. This reduction in speed and torque is achieved by decreasing the force required to turn the crank 201, thus alleviating the workload of the workers.

[0037] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0038] Example 3:

[0039] This embodiment further expands upon the above embodiment regarding the single cabinet, specifically as follows: Figure 1 , Figure 3 , Figure 6 As shown, the single cabinet includes a cabinet body 101, a housing 102, and a base 103. The base 103 is slidably connected to the slide rail 104. The cabinet body 101 is mounted on the base 103, and the housing 102 is mounted on the cabinet body 101. The housing 102 has serial number markings and relevant category markings on its side for easy retrieval. The drive shaft 208 is rotatably connected to the housing 102, and the locking ring 206 is slidably connected to the cabinet body 101. The cabinet body 101 has multiple storage compartments on both sides for storing documents. The housing 102 conceals the drive unit, exposing only the crank handle 201; this maintains a neat and aesthetically pleasing appearance and protects the relevant parts.

[0040] Furthermore, a slider 105 is provided on the base 103, the slider 105 is embedded in the slide rail 104, and the slide rail 104 is embedded in the base 103. Through the double interlocking action, the connection stability between the individual cabinet and the slide rail 104 is enhanced, ensuring that the movement of the individual cabinet is smooth and fluid.

[0041] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
