Description

Technical Field

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

[0002] In many regions, especially those with humid climates, daily storage presents numerous challenges. Traditional storage cabinets lack adequate sealing, allowing humid air to easily penetrate and cause stored items such as clothing, books, food, and valuable collectibles to become damp, moldy, or damaged. Furthermore, for certain items requiring a dry and airtight storage environment, such as certain medications, electronic components, and precision instrument parts, ordinary storage cabinets cannot meet their storage requirements, thus affecting the quality and lifespan of these items. With the improvement of people's living standards and increased awareness of proper item preservation, developing a storage cabinet that can effectively cope with humid environments and meet the needs for dry and airtight storage is particularly urgent. Utility Model Content

[0005] The drawer body includes a drawer body suitable for storing items and a drawer panel fitted to the front side of the drawer body, the drawer panel including a sealing ring.

[0006] A drawer box forming a first cavity, wherein the drawer body is adapted to be retractably received in the first cavity along its depth direction, the first cavity including a first opening for the drawer body to enter and exit, and the drawer box being relatively fixed to the cabinet assembly;

[0007] A retaining mechanism adapted to provide force along the pulling direction of the drawer body so that the sealing ring is tightly against the first cavity opening to maintain a sealed environment in the first cavity.

[0008] Preferably, the sealing ring includes a mounting ring and at least one sealing lip connected to the mounting ring. The sealing lip has a crescent-shaped, C-shaped, or U-shaped cross-section. The sealing lip includes an opening, or the sealing lip cooperates with the mounting ring to form an opening. The opening is disposed away from the first cavity opening, and the sealing lip is deformed by compression from the first cavity opening.

[0009] The mounting ring is the basic support structure of the sealing ring, while the sealing lip is the key part to achieve the sealing function. When the drawer body is pushed into the first cavity of the drawer box, the opening of the first cavity will exert a squeezing effect on the sealing lip. The sealing lip will deform so that it can fit tightly against the edge of the opening of the first cavity, filling the tiny gaps, thereby effectively preventing air from entering the first cavity from the gap between the opening and the drawer panel, creating a sealed environment inside the drawer unit.

[0010] Preferably, the first cavity has an expanding trend from the inside out. This expanding trend allows for more even and forceful compression of the sealing lip by the first cavity during the drawer body's insertion, enabling the sealing lip to better fill the gap between the cavity and the drawer panel, thus enhancing sealing performance. Alternatively, the first cavity includes an inwardly extending sealing ring adapted to abut against the sealing ring. At least a portion of the sealing lip is disposed in close contact with the first cavity.

[0011] Preferably, the thickness of the sealing lip gradually decreases from the inside to the outside. The thinner outer part is more likely to deform when squeezed, which can fit more closely to the contour of the first cavity and further improve the sealing fit.

At the same time, it is equipped with a retaining mechanism to ensure that the sealing ring always keeps in close contact with the first cavity opening, maintaining a good sealing state and ensuring that the stored items are always in a dry and suitable environment.

[0039] Second, by using drawer boxes independent of the cabinet body, the drawer boxes ensure structural integrity and sealing during manufacturing. Compared to storage boxes constructed from the cabinet body, this effectively reduces gaps caused by installation deviations. Furthermore, the independent drawer box remains relatively fixed to the cabinet components. Even if the cabinet body shakes to some extent during drawer operation, the drawer box remains relatively stable, ensuring a good fit between the sealing ring on the drawer panel and the first cavity of the drawer box, thus maintaining excellent sealing performance.

[0059] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0060] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0061] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0062] Example 1

[0063] like Figure 1-8The described storage cabinet includes a cabinet body 5 assembly and three drawer units 1 housed within the cabinet body 5 assembly. In the accompanying drawings, the drawer units 11 are shown in different sizes, all uniformly labeled as 1. The drawer units 1 of different sizes employ the same retaining mechanism 4. The sealing structure is adaptively adjusted according to the size of the drawer box 3. It is understood that specific dimensional parameters do not constitute a limitation of the invention. The drawer unit 1 includes a drawer body 2, a drawer box 3, and a retaining mechanism 4. The drawer body 2 includes a drawer main body 21 suitable for storing items and a drawer panel 22 mounted on the front side of the drawer body 21. The drawer box 3 forms a first cavity 31. The drawer body 2 is adapted to be pull-outably housed in the first cavity 31 along its depth direction. The first cavity 31 includes a first opening 311 for the drawer body 2 to enter and exit. The drawer box 3 remains relatively fixed to the cabinet body 5 assembly. The drawer panel 22 includes a sealing ring 23. The retaining mechanism 4 is adapted to provide force along the pulling direction of the drawer body 2, causing the sealing ring 23 to press tightly against the first opening 311, thereby maintaining a sealed environment in the first cavity 31.

[0064] In this embodiment, the sealing ring 23 includes a mounting ring 231 and a sealing lip 232 connected to the mounting ring 231. The sealing lip 232 has a crescent-shaped cross-section. The drawer panel 22 includes an outer panel 222 and an inner panel 223 disposed opposite to each other. A handle 225 is disposed on the outer surface for gripping. The inner panel 223 is disposed facing the cavity opening and has a mounting groove 224 protruding inward. The mounting ring 231 is adapted to be embedded in the mounting groove 224. The drawer body 21 includes a front end plate 213 disposed facing the drawer panel 22. The front end plate 213 is adapted to connect to the inner panel 223. The front end plate 213 includes an annular edge 2132, which is adapted to cooperate with the mounting groove 224 to limit the mounting ring 231. There is a clearance groove between the mounting ring 231 and the annular edge 2132 for the sealing lip 232 to extend out. The sealing lip 232 has an opening that is fitted to the mounting ring 231. The opening is positioned away from the first cavity 311, and the sealing lip 232 is deformed by the compression of the first cavity 311.

[0065] When the drawer body 2 is pushed into the first cavity 31 of the drawer box 3, the first cavity opening 311 exerts a squeezing effect on the sealing lip 232. The sealing lip 232 deforms, allowing it to tightly fit the edge of the first cavity opening 311, creating a sealed environment inside the drawer unit 1. In the sealed state, the inner panel 223 is adapted to abut against the first cavity opening 311, and the sealing ring 23 extends completely into the first cavity opening 311. The first cavity opening 311 has an expanding trend from the inside out. This expanding trend makes the squeezing of the sealing lip 232 by the first cavity opening 311 more uniform and powerful during the process of pushing the drawer body 2 in. The sealing lip 232 can better fill the gap between the cavity opening and the drawer panel 22, enhancing the sealing performance.

[0066] In this embodiment, the drawer body 21 has a main cavity 211 with an upper opening, the front end plate 213 has a secondary cavity 2131, the drawer panel 22 has an extended cavity 221, and the inner panel 223 encloses and forms an extended cavity 2231. The secondary cavity 2131 is connected to the extended cavity 2231, thereby increasing the storage space and improving storage efficiency.

[0067] In this embodiment, the retaining mechanism 4 includes a first slide rail 41, a second slide rail 42, and a return spring (not shown in the figure). The first slide rail 41 is fixed to the left and right sides of the first cavity 31, and the second slide rail 42 is disposed on the left and right sides of the drawer body 21. The first slide rail 41 and the second slide rail 42 slide in cooperation along the pulling direction of the drawer body 2, and are symmetrically distributed to ensure that the force is even when the drawer is pulled out, reducing shaking and improving the user experience. The return spring is suitable for driving the first slide rail 41 and the second slide rail 42 to move closer to each other, thereby driving the sealing ring 23 to fit tightly against the first cavity opening 311. Under the premise of ensuring sealing, the sliding cooperation of the slide rails allows the drawer body 2 to be smoothly pulled out in the drawer box 3, making operation easy. At the same time, the return spring can apply force along the depth direction of the drawer box 3, resulting in a good sealing effect.

[0068] In this embodiment, the drawer body 21 is provided with several partitions 212 to divide it into several independent storage areas, which avoids the mixing of items, makes it convenient for users to quickly find the items they need, greatly improves the utilization efficiency of storage space, and makes storage more orderly and efficient.

[0069] In this embodiment, the cabinet 5 assembly includes a cabinet 5 and a door frame assembly. The cabinet 5 includes a second cavity 55 with a second opening. The door frame assembly includes a support frame 6 and a face frame 7 adapted to cover the support frame 6. The support frame 6 includes a first main frame 61 and a first crossbeam 62 supported by the second opening. The first crossbeam 62 is adapted to divide the first main frame 61 to form a plurality of mounting openings 63. The drawer box 3 is inserted into the second cavity 55 through the mounting openings 63. The support frame 6 cooperates with the cabinet 5 to jointly support the drawer box 3.

[0070] In this embodiment, the first main frame 61 includes a first vertical rod 611 suitable for support along the height direction of the cabinet 5 and a first horizontal rod 612 suitable for support along the width direction of the cabinet 5. The left and right sides of the drawer box 3 are provided with a first stop plate 32 and a first guide rail 33. The first vertical rod 611 includes a second stop plate 613 and a first guide groove 614. The first guide rail 33 and the first guide groove 614 slide to guide the drawer box 3 into the cabinet 5. The first stop plate 32 and the second stop plate 613 abut to indicate that the installation is in place.

[0071] In this embodiment, the support frame 6 and the panel are adapted to be inserted and fastened along the depth direction of the cabinet 5. The panel 7 includes a second main frame 71 and a second crossbeam 713. The second main frame 71 extends toward the first main frame 61 with a plurality of first male buckles 714. The first main frame 61 includes a first female buckle adapted to engage with the first male buckle 714. The first crossbeam 62 extends toward the second crossbeam 713 with a plurality of second male buckles 621. The second crossbeam 713 includes a second female buckle adapted to engage with the second male buckle 621. The second main frame 71 includes a second vertical rod 711 and a second horizontal rod 712. A plurality of latches 34 are provided on the upper and lower sides of the drawer box 3. The latches 34 are adapted to engage with the second horizontal rod 712 or the second crossbeam 713, which not only improves the stability of the drawer box 3 installation, but also enhances the vertical support force and prevents the drawer box 3 from sagging and deforming.

[0072] In this embodiment, the cabinet 5 includes a top plate 51, a bottom plate 52, a back plate 53, and two side plates 54. The top plate 51, bottom plate 52, and side plates 54 together form a second cavity. The back plate 53 is provided with a support member 531 suitable for supporting the drawer box 3. The top plate 51, bottom plate 52, and side plates 54 each include a second guide post 56. The first vertical rod 611 and the first horizontal rod 612 are respectively provided with a second guide groove 615 and a second stop plate 613. The second guide post 56 and the second guide groove 615 are slidably engaged to guide the support frame 6 to be inserted into the second cavity. The second stop plate 613 abuts against the guide post to indicate that the installation is in place. The stop plate and the guide post are relatively fixedly connected. The first vertical rod 611 includes an opening area that allows some of the guide post to communicate with the first stop plate 32. The relatively fixed connection between the drawer box 3 and the cabinet 5 improves the overall integrity of the connection and helps to maintain stability when the drawer body 2 is pulled out.

[0073] Example 2

[0074] like Figure 9-10 As shown, a storage cabinet differs from Embodiment 1 in that its retaining mechanism includes a first magnetic body 43 and a second magnetic body 44. The drawer body 21 includes a drawer back panel 214, a first cavity bottom 312 is provided within a first cavity 31, the first magnetic body 43 is located in the middle of the drawer back panel 214, and the second magnetic body 44 is located at the cavity bottom. When the drawer body 21 is pushed inwards to near the first cavity bottom 312, the second magnetic body 44 is adapted to attract the first magnetic body 43, thereby holding the drawer body 21 in place and providing continuous pressure to the sealing ring 23. This ensures that the sealing ring 23 is tightly fitted against the first cavity opening 311, avoiding frictional wear in traditional mechanical structures and extending service life.

[0075] Example 3

[0076] like Figure 11-13As shown, a storage cabinet, compared to embodiment 1, differs in that the holding mechanism includes a control unit 45, a transmission unit, and a locking unit. The control unit includes a handle 451 and a rotating shaft 452 pivotally connected to the drawer panel 22. The handle 451 rotates parallel to the drawer panel 22, and the rotating shaft 452 is perpendicularly disposed through the center of the drawer panel 22. A bearing 482 suitable for supporting the rotating shaft 452 is disposed on the inner side of the drawer panel 22. One end of the rotating shaft 452 is suitable for connecting to the handle 451, and the other end of the rotating shaft 452 is suitable for connecting to the transmission unit. The locking unit includes a first locking part 46 and a second locking part 47. The first locking part 46 protrudes into the first cavity 31 adjacent to the first cavity opening 311, and is disposed perpendicular to the drawer body 2's pull-out direction. The first locking part 46 includes a first locking ramp 461, and the second locking part 47 includes a second locking ramp 471. The control unit 45 drives the second locking ramp 471 to abut against the first locking ramp 461 through the transmission unit to restrict the drawer body 2 from moving along its pulling direction, thereby keeping the first cavity 31 in a sealed environment.

[0077] In this embodiment, when the handle 451 is positioned vertically, the locking unit remains locked. When the handle 451 is positioned horizontally, the locking unit is released, and the drawer body 2 can be pulled out. It can be understood that the handle 451 replaces the pull handle 225 in Embodiment 1, but also serves to drive the second locking part 47 to move.

[0078] In this embodiment, the first locking part 46 is provided along the length direction of the first cavity 311. The first locking part 46 is respectively provided on both sides of the first cavity 31, and the second locking part 47 extends retractably through both sides of the drawer body 21. Track grooves 215 are provided on both sides of the drawer body 21, and the second locking part 47 slides with the track grooves 215, and the second locking part 47 does not disengage from the track grooves 215.

[0079] In this embodiment, the transmission assembly includes a transmission arm 481 connected to the rotating shaft 452, and two second locking portions 47 are hinged to the two ends of the transmission arm 481 in opposite directions.

[0080] Example 4

[0081] like Figure 14-18 As shown, a storage cabinet differs from embodiment 3 in that the first locking part 46 is arranged along the height direction of the first cavity 311, the first locking part 46 is located at the bottom of the first cavity 31, and the first locking inclined surface 461 is formed at its top. The bottom of the drawer body 21 is provided with a limiting groove 215, and the second locking part 47 extends retractably through the limiting groove 215 to the bottom of the drawer body 21.

[0082] In this embodiment, the drawer panel 22 is recessed inward to form an operating cavity 226 for the handle 451 to be flipped outward. The left and right sides of the handle 451 are pivotally connected to the drawer panel 22 via rotating shafts 452. The transmission mechanism includes two transmission arms 481 and a connecting rod 483. One end of the transmission arm 481 is connected to the rotating shaft 452, and the other end of the transmission arm 481 is connected to the connecting rod 483. One end of the second locking part 47 is connected to the middle of the connecting rod 483, and the other end of the second locking part 47 forms a second locking slope 471. When the handle 451 is flipped outward, it drives the transmission mechanism to rise, thereby causing the second locking slope 471 to separate from the first locking slope 461. When the handle 451 is parallel to the drawer panel 22 and completely received in the operating cavity 226, the locking unit remains locked.

[0083] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
