Description

Technical Field

[0001] This invention belongs to the field of furniture equipment technology, and specifically relates to an adjustable cabinet with concealed connectors. Background Technology

[0002] The cabinet body is the basic unit that makes up a furniture cabinet. It is generally composed of a top panel, shelves, a bottom panel, left and right side panels, and a back panel, all assembled with connectors. Currently, the mainstream connection method uses three-in-one or four-in-one connectors to connect the panels. However, this method exposes parts of the connector structure, affecting the internal appearance of the cabinet. If concealed connectors were used instead of three-in-one or four-in-one connectors, the cabinet would be non-adjustable and would have lower strength and durability.

[0003] In response, patent document CN211632431U discloses a concealed movable connector for cabinet shelves, including a male fastener and a female fastener. Both the male and female fasteners are straight strips. One side of the female fastener has a groove corresponding to the male fastener, and the other side of the female fastener is fixedly connected to the side of the cabinet shelf. After the male and female fasteners are connected, the male fastener can slide relative to the female fastener within the groove, thereby allowing the cabinet shelf to move forward and backward. The concealed connecting fastener for cabinet shelves provided by this invention has a simple structure, is easy to manufacture, and effectively simplifies the connection between the cabinet shelf and the cabinet body. After installation, it transforms a traditional fixed shelf into a movable shelf, enabling forward and backward sliding. Furthermore, the components are hidden after installation, ensuring a clean and aesthetically pleasing cabinet appearance. However, the base plate in this solution cannot be moved, making it impossible to install support feet underneath (making height adjustment inconvenient after installation), thus making it unsuitable for uneven ground. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a cabinet that can conceal connectors while allowing for adjustable support leg height.

[0005] The objective of this invention can be achieved through the following technical solution: an adjustable cabinet with concealed connectors, comprising:

[0006] The main body is provided with at least one top plate, a bottom plate, a back plate and at least two side plates. The top plate, side plates and bottom plate are connected in sequence and enclose a U-shaped frame. The back plate is set inside the frame and is snapped with the top plate, side plates and bottom plate respectively. The bottom plate and top plate extend away from the back plate, and the extension distance of the bottom plate is less than the extension distance of the top plate.

[0007] The movable panel is movably connected to two side panels via a connecting assembly. It includes a first movable panel, which is positioned at a greater distance from the ground than the base plate. When the first movable panel moves along the width of the side panels to abut against the back panel, it covers the exposed surface of the base plate.

[0008] In the aforementioned adjustable cabinet with a concealed connector, the side panel is provided with a support foot near the ground, wherein the extension distance of the base plate is less than the distance from the support foot to the back panel, so that the support foot is exposed in the human's field of vision.

[0009] In the aforementioned adjustable cabinet with a concealed connector, the support leg includes a fixed part and an adjustable part. The fixed part is movably connected to the adjustable part and is connected to the side panel. The height of the support leg can be adjusted by connecting the fixed part and the adjustable part at different heights.

[0010] In the aforementioned adjustable cabinet with a concealed connector, when the first movable plate moves toward the back panel and abuts against the back panel, the side of the first movable plate facing the bottom plate is attached to the bottom plate so that the bottom plate provides support for the first movable plate.

[0011] In the aforementioned adjustable cabinet with a concealed connector, a kick plate is provided on the side of the first movable plate facing the human body, and a human body sensor switch is also provided on the side of the kick plate facing the human body.

[0012] In the aforementioned adjustable cabinet with a concealed connector, an extension plate is provided on the side of the first movable plate facing the human body. The extension plate is located above the kick plate. The side of the extension plate facing the ground is provided with a mounting groove that extends along the length of the extension plate.

[0013] In the aforementioned adjustable cabinet with a concealed connector, a storage box is provided on the side of the first movable plate facing the ground for accommodating electrical appliances or miscellaneous items.

[0014] In the aforementioned adjustable cabinet with a concealed connector, the movable plate further includes a second movable plate and a third movable plate. The second movable plate is located in the middle of the frame and is movably connected to the side plate via a connecting component. The third movable plate is located below the top plate and is movably connected to the side plate via a connecting component. When the third movable plate moves along the width direction of the side plate to abut against the back plate, it covers the exposed surface of the top plate facing the ground.

[0015] In the aforementioned adjustable cabinet with a concealed connector, the connecting assembly includes a shelf pin and a shelf groove. The shelf pin is located on the side of the two side panels facing the movable panel, and the shelf groove is located on both sides of the movable panel facing the side panels. The shelf pin is engaged in the shelf groove and forms a sliding connection with the shelf groove.

[0016] In the aforementioned adjustable cabinet with a concealed connector, the shelf pins are provided in at least two sets, with at least two in each set. The two shelf pins are arranged horizontally in a straight line, and one of the shelf pins is provided with a receiving groove for the light wire to pass through.

[0017] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0018] 1. By setting a base plate with an extension distance less than the distance from the support legs to the back panel, and simultaneously setting a first movable plate that is movably connected to the side panel, and allowing the first movable plate to move along the width of the side panel until it abuts against the back panel, thus covering the exposed surface of the base plate, the base plate improves the connection strength of the main body and ensures the stability of the cabinet. It also provides the cabinet with operating space for adjusting the support legs, thus increasing the application range of the cabinet. Furthermore, the movable plate hides the exposed parts of the connectors on the base plate under the first movable plate, resulting in a flat and aesthetically pleasing interior space for the cabinet.

[0019] 2. By setting adjustable support feet at the bottom of the side panels, the cabinet body can maintain its stability on uneven ground by adjusting the four support feet, effectively expanding the application scenarios of the cabinet.

[0020] 3. When the first movable plate moves towards the back plate and comes into contact with the back plate, the side of the first movable plate facing the bottom plate is in close contact with the bottom plate, so that the bottom plate supports the first movable plate, increasing the bearing area of ​​the first movable plate, while avoiding damage to the connecting components due to excessive force, effectively improving the service life of the connecting components and the cabinet.

[0021] 4. By setting an installation groove on the side of the outer extension plate facing the ground for the installation of light strips, the cabinet can be fitted with light strips of different colors according to user needs, which enriches the night vision effect of the cabinet and improves the appearance of the cabinet.

[0022] 5. By setting a receiving groove on the shelf pin to allow the light wire to pass through, the exposed light wire in the storage space of the cabinet is avoided, making the cabinet more neat and beautiful. At the same time, solid shelf pins are set to support the movable board, preventing the shelf pin from being damaged due to the excessive weight of the movable board. While enriching the function of the shelf pin, it also ensures the connection strength between the shelf pin and the movable board, thereby ensuring the stability of the movable board when it is pushed and pulled.

Detailed Implementation

[0030] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0031] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0032] like Figures 1 to 6 As shown in the figure, an adjustable cabinet with concealed connectors provided in this embodiment of the invention includes a top plate 110, a bottom plate 120, a back plate 130, a side plate 140, a first movable plate 210, a second movable plate 220, a third movable plate 230, a connecting component 300, and a support leg 400.

[0033] An adjustable cabinet with concealed connectors includes a body 100, at least one top plate 110, a bottom plate 120, a back plate 130, and at least two side plates 140. The top plate 110, side plates 140, and bottom plate 120 are sequentially connected and enclose a U-shaped frame. The back plate 130 is located on the inner side of the frame away from the human body and engages with the top plate 110, side plates 140, and bottom plate 120. The bottom plate 120 and top plate 110 extend away from the back plate 130, and the extension distance of the bottom plate 120 is less than that of the top plate 110, providing operating space for adjusting the support legs 400, thereby increasing the application range of the cabinet. In addition, the connection between the bottom plate 120 and the side plates 140 and back plate 130 effectively improves the connection strength of the body 100, ensuring the stability and support strength of the frame.

[0034] The movable panel 200 is movably connected to two side panels 140 via a connecting assembly 300. It includes a first movable panel 210, which is positioned higher than the bottom panel 120. When the first movable panel 210 moves along the width of the side panel 140 to abut against the back panel 130, it covers the exposed surface of the bottom panel 120, thus hiding the exposed portion of the connector 500 beneath the first movable panel 210. This results in a flat and aesthetically pleasing interior space for the cabinet.

[0035] Specifically, such as Figure 1 , Figure 4 As shown, in this embodiment, the cabinet body 100 is composed of loose panels, including a rectangular top panel 110, a bottom panel 120, a back panel 130, and two rectangular side panels 140. The back panel 130 and the side panels 140 extend vertically to form the height of the cabinet. The bottom panel 120 is horizontally positioned on the side panel 140 closest to the ground and is connected to the side panel 140 via a connector 500 (a three-in-one connector or a four-in-one connector). The top panel 110 is horizontally positioned on the side panel 140 furthest from the ground. On the side, the top plate 110, the side plate 140, and the bottom plate 120 are connected to the side plate 140 via connectors 500 (three-in-one connectors or four-in-one connectors), so that the top plate 110, the side plate 140, and the bottom plate 120 are enclosed to form a U-shaped frame. Furthermore, the top plate 110, the bottom plate 120, and the side plate 140 have grooves on their sides facing the inside of the frame. The back plate 130 is fitted into the grooves to form the body 100. By using connectors 500 (three-in-one connectors or four-in-one connectors), the connection between the various panels of the body 100 can be made more stable and firm.

[0036] In this embodiment, both the top plate 110 and the bottom plate 120 extend away from the back plate 130. The extension distance of the bottom plate 120 is less than that of the top plate 110, so that the front end of the bottom of the body 100 is connected to the bottom of the side plate 140, providing operating space for the adjustment of the support foot 400.

[0037] Preferred, such as Figures 1 to 2 As shown, in this embodiment, the extension distance of the base plate 120 is less than the distance from the support foot 400 to the back plate 130, so that the support foot 400 can be fully exposed in the human field of vision, making it convenient for the operator to adjust the height of the support foot 400, thereby improving the applicability of the cabinet.

[0038] In this embodiment, the side plate 140 is provided with a plurality of support feet 400 near the ground. Preferably, four support feet 400 are provided, arranged in pairs at the bottom of a single side plate 140. Each support foot 400 includes a fixing part 410 and an adjusting part 420. The fixing part 410 and the adjusting part 420 are movably connected. The fixing plate is connected to the side plate 140. By connecting the fixing part 410 and the adjusting part 420 at different heights, the height of the support foot 400 can be adjusted.

[0039] In this embodiment, the outer wall of the fixing part 410 is connected to the side plate 140. One end of the adjusting part 420 extends into the fixing part 410 and is movably connected to the fixing part 410, while the other end extends toward the ground and contacts the ground. By engaging the outer walls of the fixing part 410 and the adjusting part 420 at different heights, the height of the supporting feet 400 can be adjusted, so that the body 100 can maintain the stability of the bottom on uneven ground by adjusting the four supporting feet 400, effectively expanding the application scenarios of the cabinet.
