Description

Technical Field

[0001] This utility model relates to the field of storage cabinet technology, and in particular to a file cabinet. Background Technology

[0002] Currently, for filing cabinets requiring locking, the cabinet doors are normally locked, and files can be stored when the doors are opened. Most of these cabinets use an automatic pop-up opening mechanism, where the door quickly opens via a spring or electromagnetic device after the user completes authentication (such as scanning a code or entering a password). While this design achieves rapid opening, it also has significant drawbacks:

[0003] Loud noise: The impact force when the cabinet door pops open is strong, which can easily generate a lot of noise, especially in places where a quiet environment is required, affecting the people around.

[0004] Safety hazard: The cabinet door opens too quickly. If the user is close enough, they may not be able to avoid it and may collide with their body (such as head, arm, etc.), posing a risk of personal injury.

[0005] Hygiene issues: Users need to manually push the door back when closing it, and frequent contact with the door handle or surface by multiple people can easily become a medium for the spread of bacteria and viruses, especially increasing the risk of contact infection during flu season.

[0006] To address the aforementioned issues, it is imperative to optimize the opening and closing structure of the filing cabinet doors. This would ensure convenience while reducing noise, eliminating safety hazards, and minimizing direct user contact, thereby enhancing the safety, comfort, and hygiene of the filing cabinet.

[0046] 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.

[0047] The purpose of this utility model is to provide a filing cabinet to solve the problems existing in the prior art. It uses a door opening and closing mechanism to control the opening and closing of the door panel and a door lock mechanism to lock the door panel. The door panel can be opened and closed at a set speed without human contact, which can reduce the impact of noise and personal injury caused by the sudden opening of the door panel, and reduce direct contact with users, thereby improving the safety, comfort and hygiene of the filing cabinet.

[0048] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] like Figures 1-10 As shown, this utility model provides a filing cabinet, including at least one storage compartment 2. When more than one number of storage compartments 2 are provided, different storage compartments 2 can be connected and expanded horizontally and vertically (e.g., Figure 10 As shown), after adding the frame and other structures, it forms the complete storage cabinet 1 (as shown). Figure 1 and Figure 2 As shown, the volume of a single storage compartment 2 and the size of the storage cabinet 1 are set according to actual needs. Different storage compartments 2 can have the same volume, or they can be planned as storage compartments 2 of different lengths and widths to facilitate the storage of files of different sizes. The storage compartment 2 includes a compartment body 22, a door panel 21, a door lock mechanism 23, and a door opening and closing mechanism 24. Each panel constituting the compartment body 22 can be used independently or shared with the compartment body 22 of adjacent storage compartments. The compartment body 22 is used to store files and has an access port for storing and retrieving files. The door panel 21 is hinged to one side of the access port. This "one side" can be the top, side, or bottom; that is, the opening and closing method of the door panel 21 is not limited to left-opening or right-opening, but can also be top-opening or bottom-opening. The embodiment provided in this utility model uses the common left-opening method. The door panel 21 is used to close the access port to ensure the security of stored files. The door lock mechanism 23 is used to lock the door panel 21 and the compartment 22. The door lock mechanism 23 can be a magnetic structure, maintaining magnetic attraction after the door is closed to ensure the door panel 21 is locked; or it can be a bolt structure, using an electric telescopic rod to lock the bolt. The door opening and closing mechanism 24 includes a connecting rod 241, a linear guide structure 242, and a linear drive structure 243. The first end of the connecting rod 241 is hinged to the door panel 21, and the second end is hinged to the movable part of the linear guide structure 242. The fixed part of the linear guide structure 242 is connected to the compartment 22, and the movable part is also connected to the linear drive structure 243. The linear drive structure 243 can be a telescopic cylinder type drive structure or a linear module type drive structure.

[0050] When the linear drive structure 243 is activated, it can push the movable part to move linearly relative to the fixed part, and at the same time, drive the connecting rod 241 to swing. At this time, the connecting rod 241 is the first side, the distance between the hinge position of the connecting rod 241 on the door panel 21 and the door hinge is the second side, and the distance between the door hinge and the movable part is the third side. The first side, the second side and the third side form a variable triangle. The included angle between the second side and the third side is the opening angle of the door panel 21. Therefore, by adjusting the size of this included angle, the opening and closing of the door panel 21 can be controlled.

[0051] This invention changes the non-active door opening and closing method in the prior art. It uses the door opening and closing mechanism 24 to control the opening and closing of the door panel 21 and the door lock mechanism 23 to lock the door panel 21. Thus, the opening and closing action of the door panel 21 can run at a set speed without human contact. This can reduce the impact of noise and personal injury caused by the sudden opening of the door panel 21, and reduce direct contact with users to avoid cross-infection of diseases, thereby improving the safety, comfort and hygiene of the storage cabinet 1.

[0052] In one implementation, such as Figure 4 and Figure 5 As shown, the compartment 22 adopts a rectangular cabinet structure, which includes a top plate, a bottom plate, a back plate, and two side plates. The bottom plate is provided with a straight guide structure 242. When installing, a slot can be made in the bottom plate so that the straight guide structure 242 can be placed in the slot, reducing the space occupation and the impact on other compartments 22. To ensure the enclosure, a baffle 25 can also be provided to cover the slot.

[0053] In one implementation, such as Figure 5 and Figure 6 As shown, the linear guide structure 242 includes a slider 2421 and a guide plate 2422. A first groove 24221 is formed on the guide plate 2422. The slider 2421 is slidably disposed in the first groove 24221. The cross-sectional shape of the first groove 24221 is consistent with the cross-sectional shape of the guide plate, for example, both adopting a T-shaped structure or a dovetail structure. The guide plate 2422 is fixedly connected to the base plate. In this example, the guide plate 2422 is located in the groove of the base plate. The guide plate 2422 is set parallel to the side panel of the rectangular cabinet structure and extends from the rear panel to the access port, ensuring that the slider 2421 has sufficient sliding distance in the first groove 24221 of the guide plate 2422.

[0054] In one implementation, such as Figure 5 and Figure 6 As shown, the linear guide structure 242 also includes a cover plate 2423, which covers the first slide groove 24221 to seal it and prevent dust and other contaminants from affecting the sliding of the slider 2421 within the first slide groove 24221. To ensure that the slider 2421 drives the connecting rod 241 and provides the connecting rod 241 with suitable room for movement, the side of the cover plate 2423 is also provided with a strip groove for the connecting rod 241 to move.

[0055] In one implementation, such as Figure 5 and Figure 6As shown, the linear drive structure 243 includes a motor 2431, a lead screw 2432, and a rotating support 2433. The slider 2421 has an internal thread that matches the lead screw 2432. The slider 2421 is threadedly connected to the lead screw 2432. When the lead screw 2432 rotates, the slider 2421 is restricted by the first groove 24221 and can only move linearly, not rotate. Therefore, the rotation of the lead screw 2432 can be converted into linear movement of the slider 2421. The rotating support 2433 is located at both ends along the length of the first groove 24221. In practice, the rotating support 2433 can be located inside the first groove 24221 or on the outer top surface of the first groove 24221, and fixed by welding, screws, or other methods. The lead screw 2432 is arranged along the length of the first slide groove 24221 and is rotatably connected to the rotating support 2433. Under the support of the rotating support 2433, the lead screw 2432 only rotates circumferentially and is limited to axial movement. The end of the lead screw 2432 away from the door panel 21 is connected to the motor 2431. The motor 2431 is fixed to the back panel of the rectangular cabinet structure by a bracket 2434. The bracket 2434 can be a bent plate to facilitate the fixation of the motor 2431.

[0056] The motor 2431 is fixed to the rear panel of the rectangular cabinet structure, facilitating maintenance and repair. Additionally, a maintenance door 6 can be installed at the rear of the storage cabinet 1. Opening the maintenance door 6 allows for maintenance of the controller, wiring, etc., of the storage cabinet 1. The maintenance door 6 is equipped with a mechanical lock 7. Since the maintenance door 6 generally does not require remote control or frequent opening, a common lock structure is sufficient for the mechanical lock 7. Furthermore, using a rear-mounted maintenance door 6 reduces the space occupied at the front, thereby increasing the number of storage compartments 2 and maximizing the utilization of the storage cabinet 1's space.

[0057] In one implementation, such as Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, the door lock mechanism 23 includes a lock body 231, a bolt 232, and an electromagnet 233. The lock body 231 is installed on the door panel 21 and rotates with the door panel 21. When the door panel 21 is closed, the bolt 232 can engage and lock with the lock opening 2211 on the cabinet body 22. The lock body 231 is provided with a second slide groove 2311, and the rectangular cabinet structure is provided with a third slide groove 221 corresponding to the position of the second slide groove 2311. The bolt 232 is slidably disposed in the second slide groove 2311, and after the door panel 21 is closed, the bolt 232 can slide in the third slide groove 221. That is to say, after the door panel 21 is closed, the bolt 232 can slide in both the second slide groove 2311 and the third slide groove 221 simultaneously. An electromagnet 233 is installed inside the lock body 231, which is made of ferromagnetic material or has a ferromagnetic part that can be magnetically attracted to the electromagnet 233. By controlling whether the electromagnet 233 is energized, the position of the bolt 232 can be adjusted using the electromagnet 233. The third slide groove 221 is provided with a lock opening 2211. When the bolt 232 is adjusted to a suitable position, the height of the bolt 232 matches the height of the lock opening 2211, allowing the bolt 232 to move laterally along the lock opening 2211. With the cooperation of the door opening and closing mechanism 24, when the bolt 232 is adjusted to a suitable height, the door opening and closing mechanism 24 is activated, and the connecting rod 241 pushes the door panel 21, realizing the opening action.

[0058] In one implementation, such as Figure 7 and Figure 9As shown, the latch 232 includes a T-shaped head end 2321 and a straight tail end 2322. The length direction of the straight tail end 2322 is parallel to the length direction of the horizontal arm of the T-shaped head end 2321. The third slide groove 221 adopts a T-shaped groove. The T-shaped head end 2321 is used to slide in conjunction with the T-shaped groove. When the T-shaped head end 2321 enters the T-shaped groove from the lock opening 2211, the T-shaped head end 2321 can slide within the T-shaped groove. The T-shaped head end 2321 cannot disengage from the T-shaped groove at any other position in the T-shaped groove except for the lock opening 2211, thereby locking the opening direction of the latch 232. The flat end 2322 is used to abut against the return spring 234. The direction of the force exerted by the return spring 234 on the flat end 2322 is opposite to the direction of the force exerted by the electromagnet 233 on the flat end 2322. When the electromagnet 233 is not energized, the return spring 234 pushes the flat end 2322 against the first limiting structure, so that the locking tongue 232 is kept in the first set position, which is the locked position (the position where the T-shaped head end 2321 cannot pass through the lock opening 2211). When the electromagnet 233 is energized, the magnetic attraction of the electromagnet 233 can overcome the elastic force of the return spring 234, so that the flat end 2322 abuts against the second limiting structure opposite to the first limiting structure. At this time, the locking tongue 232 is in the second set position, which is the open position (the position where the T-shaped head end 2321 can pass through the lock opening 2211). In this example, there are two reset springs 234. The two reset springs 234 abut against the two ends of the I-shaped tail 2322 respectively. At the same time, the two ends of the I-shaped tail 2322 are provided with circular grooves, which can be used to limit the radial position of the reset springs 234 and prevent the reset springs 234 from shifting when applying force.

[0059] In one implementation, such as Figure 9 As shown, the side of the T-shaped head end 2321 near the lock opening 2211 is a downward sloping surface 23211, and the corresponding T-shaped groove extends vertically. The lock opening 2211 has an edge for abutting against the sloping surface 23211. When closing the door, the latch 232 gradually moves towards the third slide groove 221. As the latch 232 moves towards the third slide groove 221, the edge remains in contact with the sloping surface 23211, pushing the latch 232 upwards and through the lock opening 2211. After passing through the lock opening 2211, the flat end 2322 of the latch 232 is acted upon by the return spring 234, causing the latch 232 to move downwards as a whole. At this point, the T-shaped head end 2321 enters the T-shaped groove.

[0060] The door lock mechanism 23 of this utility model is equipped with an electromagnet 233 and a return spring 234. The electromagnet 233 can use its magnetic attraction to the latch 232 and the return spring 234 can use its pushing force to adjust the position of the latch 232, so that the latch 232 can smoothly reach the lock mouth 2211 and open smoothly under the action of the door opening and closing mechanism 24. During the closing process, the latch 232 can use the cooperation between the inclined surface 23211 of the latch 232 and the edge of the lock mouth 2211 to make the latch 232 automatically enter the lock mouth 2211 and lock under the pushing force of the return spring 234. The locking process and the door panel 21 after locking are stable and reliable. Moreover, the locked door panel 21 does not need to consume extra energy before waiting for the next opening, realizing low power consumption door opening and closing action.

[0061] In one implementation, such as Figure 7 As shown, the door lock mechanism 23 also includes a guide post 235. One end of the guide post 235 is connected to the middle of the flat-bottomed tail end 2322. For example, the middle of the flat-bottomed tail end 2322 has a through hole, and the guide post 235 is inserted into the through hole for fixation. Alternatively, the guide post 235 can be connected to the bottom surface of the flat-bottomed tail end 2322 by welding or other methods, in which case the flat-bottomed tail end 2322 does not need to have a through hole. The other end of the guide post 235 is slidably connected to the shaft hole 2312 in the lock body 231. The shaft hole 2312 guides the guide post 235, further ensuring the accuracy of the movement position of the bolt 232.

[0062] In one embodiment, a control module is also included. The control module is electrically connected to the electromagnet 233 and the motor 2431 respectively. After receiving the unlocking signal, the control module controls the electromagnet 233 to attract the bolt 232, so that the bolt 232 moves upward. At the same time, it controls the motor 2431 to rotate to push the door panel 21 to rotate and open the door.

[0063] In one embodiment, the storage cabinet 1 is provided with casters 5 at its bottom, which allows the storage cabinet 1 to be easily moved to the desired location. The casters 5 can be ferrules, which can support the storage cabinet 1 and limit its position after the ferrules are locked.

[0064] In one embodiment, the system also includes a Bluetooth positioning module 3 and a human body sensor light 4. Both the Bluetooth positioning module 3 and the human body sensor light 4 are located on the top of the storage cabinet 1. The Bluetooth positioning module 3 is fixed behind the human body sensor light 4. The Bluetooth positioning module 3 is used to determine the relative position of the storage cabinet 1 and the mobile terminal. Specifically, the Bluetooth positioning module 3 communicates with the Bluetooth signal of the mobile terminal (e.g., a mobile phone) carried by the person accessing the documents to determine whether the mobile terminal is within the Bluetooth coverage range of the Bluetooth positioning module 3. Only within the Bluetooth coverage range of the Bluetooth positioning module 3 can the door be opened, thereby increasing the security of the equipment.

[0065] A document, approximately 2-3 pages long, requires relatively little space when rolled up. A storage compartment 2 measuring 12cm high x 13cm wide x 35cm deep is sufficient. More storage compartments 2 can be set up in a single storage cabinet 1, while controlling the cabinet's footprint. In this example, a single storage cabinet 1 has 72 storage compartments 2, and two storage cabinets 1 have 144 storage compartments 2, which basically meets daily storage needs.

[0066] When personnel accessing documents (especially those retrieving documents, who can directly open door panel 21 without using Bluetooth positioning module 3 for personnel location and identification) enter the designated security area covered by Bluetooth positioning module 3 on storage cabinet 1, they can access documents. The process is as follows: When personnel enter the designated security area and are within the sensing range of human body sensor 4, the human body sensor 4 lights up. Personnel accessing documents then operate via a mobile terminal (e.g., a mobile phone), sending a switch command to the server. The background management program detects this via Bluetooth positioning module 3. Once the personnel accessing the files are within the designated secure area and pass the security check, the backend server initiates an unlocking command. This command is transmitted to the control module via Bluetooth positioning module 3. Upon receiving the unlocking command, the control module opens the door lock mechanism 23 of the corresponding storage compartment 2, simultaneously driving the corresponding opening / closing mechanism 24 to open the door panel 21 of the corresponding storage compartment 2, allowing files to be stored or retrieved. Then, the opening / closing mechanism 24 activates again (the activation time can be set, for example, automatically starting the closing action after 20 seconds of opening, or it can be activated again via a mobile terminal) to automatically close the door panel 21. Additionally, an ultraviolet disinfection lamp can be installed. After the door is closed, the ultraviolet disinfection lamp in storage compartment 2 is turned on and performs disinfection for a certain period of time. After disinfection is complete, the ultraviolet disinfection lamp is turned off.

[0067] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
