Technical Field

[0001] This application relates to the field of locker technology, and in particular to a filing cabinet. Background Technology

[0002] Filing cabinets are storage furniture used to classify, securely store, and manage large amounts of paper documents, files, or other items. They are an indispensable infrastructure in modern offices and organizational management.

[0003] The filing cabinet includes a main body with doors that rotate on both sides. The doors include a first door and a second door. A dustproof baffle is installed along the inner edge of the first door. The dustproof baffle is typically fixed to the first door. When the first door is closed, the inner edge of the second door abuts against the outer surface of the dustproof baffle.

[0004] Regarding the aforementioned technologies, when closing the cabinet door, the first cabinet door must be closed first, followed by the second cabinet door. Conversely, when opening the cabinet door, the second cabinet door must be opened first, making it inconvenient for staff to open and close the filing cabinet. Utility Model Content

[0005] To facilitate the opening and closing of the filing cabinet by staff, this application provides a filing cabinet.

[0006] The filing cabinet provided in this application adopts the following technical solution: A filing cabinet includes a cabinet body, a first cabinet door hinged to one side of the cabinet body, and a second cabinet door hinged to the other side of the cabinet body and cooperating with the first cabinet door; a dustproof baffle is movably installed on the side of the first cabinet door near the second cabinet door; a hinge assembly is provided between the first cabinet door and the dustproof baffle; the hinge assembly includes a hinge seat installed on the first cabinet door, a movable member vertically rotatably installed on the hinge seat and used to connect the dustproof baffle, and a drive torsion spring installed on the hinge seat and driving the movable member to rotate; the drive torsion spring drives the dustproof baffle installed on the movable member to always have a tendency to rotate inward.

[0007] By adopting the above technical solution, the filing cabinet consists of a main body, a first cabinet door, and a second cabinet door, facilitating the storage and retrieval of documents. A dustproof baffle is movably installed on the first cabinet door to prevent dust from entering the cabinet. A hinged assembly allows the dustproof baffle to rotate, with a torsion spring driving the baffle to always rotate inwards. When the operator opens the first cabinet door, the dustproof baffle rotates inwards, allowing for smooth opening of the first cabinet door without obstruction from the second cabinet door. It also facilitates closing the first cabinet door when the second cabinet door is closed, making it convenient for staff to open and close the cabinet doors.

[0008] Optionally, the hinge base includes a hinge base plate, a hinge shaft mounted on the hinge base plate, and a mounting protrusion arranged on the side of the hinge base plate for fixing the hinge shaft; the movable component includes a rotating sleeve rotatably sleeved on the hinge shaft, a movable block connected to the rotating sleeve, and a fixing block connected to the movable block for connection and fixing of the dustproof baffle; both ends of the rotating sleeve abut against the mounting protrusion, and the rotating sleeve has arrangement holes for arranging the drive torsion spring.

[0009] By adopting the above technical solution, the specific structure of the hinge base and the movable component is disclosed. The hinge base, composed of the hinge base plate, hinge shaft, and mounting protrusion, provides a stable mounting foundation for the movable component. The mounting protrusion can fix the hinge shaft. The movable component, composed of the rotating sleeve, movable block, and fixed block, can rotate on the hinge shaft. The mounting protrusions at both ends of the rotating sleeve ensure the stability of the dustproof baffle's rotation and reduce the probability of slippage. The arrangement holes in the rotating sleeve facilitate the arrangement of the drive torsion spring, allowing the drive torsion spring to drive the dustproof baffle to flip inward.

[0010] Optionally, the hinge base plate is provided with a limiting baffle on the side opposite to the hinge shaft to limit the moving part from overturning inward.

[0011] By adopting the above technical solution, a limiting baffle is set on the side of the hinge base plate facing away from the hinge shaft, which can limit the rotation range of the moving parts, prevent the dustproof baffle from rotating excessively inward, and ensure that the dustproof baffle rotates at a predetermined angle and range, which facilitates the opening and closing of the cabinet door.

[0012] Optionally, the drive torsion spring is sleeved on the hinge shaft, the drive torsion spring having a first torque arm for abutting the movable member, and the drive torsion spring having a second torque arm for abutting the hinge base plate.

[0013] By adopting the above technical solution, the dustproof baffle of the filing cabinet can be made to flip inward by the first torque arm of the drive torsion spring, and the second torque arm abuts against the hinged base plate so that the drive torsion spring has a stabilizing effect.

[0014] Optionally, there are two hinge seats, which are arranged symmetrically on the inner edge of the first cabinet door, and the movable parts are arranged in a one-to-one correspondence with the hinge seats.

The first cabinet door 2 and the second cabinet door 3 are connected to the side wall panels 12 by hinges.

[0033] Reference Figure 1 and Figure 2A dustproof baffle 4 is movably installed on the side of the first cabinet door 2 near the second cabinet door 3. In this embodiment, the dustproof baffle 4 is a square baffle with a width not exceeding 4 cm and a thickness not exceeding 5 mm. A hinge assembly 5 is provided between the first cabinet door 2 and the dustproof baffle 4. The hinge assembly 5 includes a hinge seat 51 installed on the first cabinet door 2, a movable part 52 vertically rotatably installed on the hinge seat 51 for connecting the dustproof baffle 4, and a drive torsion spring 53 installed on the hinge seat 51 for driving the movable part 52 to rotate. The drive torsion spring 53 drives the dustproof baffle 4 installed on the movable part 52 to always have a tendency to rotate inward. The hinge seat 51 is installed on the inner edge of the first cabinet door 2.

[0034] Reference Figure 2 and Figure 3 The hinge base 51 includes a hinge base plate 511, a hinge shaft 512 for mounting the hinge base plate 511, and mounting protrusions 513 arranged on the side of the hinge base plate 511 for fixing the hinge shaft 512. In this embodiment, there are two mounting protrusions 513, which are symmetrically arranged on the side of the hinge base plate 511, one above the other. The movable component 52 includes a rotating sleeve 521 disposed on the hinge shaft 512, a movable block 522 connected to the rotating sleeve 521, and a fixing block 523 connected to the movable block 522 and for connecting and fixing the dustproof baffle 4. The two ends of the rotating sleeve 521 abut against the mounting protrusions 513, and the rotating sleeve 521 has arrangement holes 5211 for arranging the drive torsion spring 53.

[0035] Reference Figure 3 and Figure 4 The drive torsion spring 53 is sleeved on the hinge shaft 512. The drive torsion spring 53 has a first torsion arm 531 for abutting against the movable part 52 and a second torsion arm 532 for abutting against the hinge base plate 511. The dust cover 4 of the filing cabinet has a tendency to flip inward by abutting against the first torsion arm 531 of the drive torsion spring 53, and the second torsion arm 532 abutting against the hinge base plate 511 makes the drive torsion spring 53 have a stabilizing effect.

[0036] Reference Figure 4 When the first cabinet door 2 is opened, in order to prevent the dustproof baffle 4 from overturning inward, a limiting baffle 54 is provided on the side of the hinge base plate 511 facing away from the hinge shaft 512 to limit the inward overturning of the movable part 52. The limiting baffle 54 is perpendicular to the hinge base plate 511 and is connected to the mounting protrusion 513. The limiting baffle 54 and the mounting protrusion 513 together form a movable groove for the movable part 52 to rotate.

[0037] Reference Figure 1Two hinge seats 51 are provided on the inner edge of the first cabinet door 2. The two hinge seats 51 are arranged symmetrically vertically, and the movable part 52 is arranged in a one-to-one correspondence with the hinge seats 51.

The first handle part 23 has a first operating groove for the operator to open and close the cabinet door, and the second handle part 33 has a second operating groove for the operator to open and close the cabinet door.

[0042] Combination Figures 1 to 7The implementation principle of a filing cabinet according to an embodiment of this application is as follows: A reversible dustproof baffle 4 is installed on the first cabinet door 2. The cabinet door can be flipped through the cooperation of the hinge seat 51, the movable part 52, and the drive torsion spring 53. When the first cabinet door 2 is opened, the dustproof baffle 4 disengages from the abutting protrusion 111 of the top cabinet panel 11 and flips inward at a certain angle under the action of the drive torsion spring 53, thereby avoiding interference from the second cabinet door 3 during the opening and closing process. When the cabinet door is closed, the top inner side of the dustproof baffle 4 abuts against the abutting protrusion 111 of the top cabinet panel 11, so that the dustproof baffle 4 returns from the inward flipped state to the horizontal state, which just covers the gap between the first cabinet door 2 and the second cabinet door 3, effectively playing a dustproof role. Meanwhile, the first ball-head spring plunger 22 and the second ball-head spring plunger 32 engage with the plunger locking groove 112 of the top cabinet plate 11, and together with the first handle part 23 and the second handle part 33, enable the operator to conveniently and reliably complete the opening and closing of the cabinet door.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
