Description

Technical Field

[0001] This utility model relates to a door panel assembly and a storage cabinet. Background Technology

[0002] Lockers, as common storage devices in daily life, are widely used in homes, offices, and public places. The rationality of their structural design and ease of use directly affect user experience and the product's market competitiveness. However, existing plastic lockers generally have some problems with the connection structure between the door panel and the cabinet body.

[0003] For example, after prolonged use, door panels are prone to sagging, leading to a loose fit between the door panel and the cabinet body, resulting in loosening or excessive gaps. Furthermore, existing storage cabinet door hinge structures often use a circular L-shaped hinge with a hinge cover. This structure not only requires additional parts, increasing manufacturing costs, but also complicates the assembly process, impacting production efficiency. Simultaneously, the insufficiently tight fit between the hinge and the cabinet body can easily cause door panels to wobble or detach, reducing the overall stability and lifespan of the storage cabinet. Summary of the Invention

[0004] This utility model discloses a door panel assembly and a storage cabinet, which aims to solve the problems mentioned above.

[0005] The present invention adopts the following solution:

[0006] A door panel assembly includes a door panel body that can be installed on a cabinet, the body having an installation space disposed therein; it also includes a door hinge that is vertically movable within the installation space, the body having a through hole communicating with the installation space, one end of the door hinge being configured to extend out of the installation space through the through hole; and it further includes an elastic element and / or a snap-fit ​​block configured to securely connect the body to the cabinet.

[0007] In this embodiment of the utility model, the door panel assembly includes a spring that can drive one end of the door hinge to move outward toward the installation space; the elastic element is an elastic sheet disposed at one end of the door hinge, the elastic sheet can deform under external force, and the elastic sheet is provided with an outwardly protruding snap-fit ​​block.

[0008] In this embodiment of the utility model, a window is provided on the side wall of the main body, and the window can communicate with the installation space. A handle is provided around the door hinge, and the handle can be adapted to and connected to the window. Driving the handle provided at the window can drive the door hinge to move up and down.

[0009] In this embodiment of the present invention, a protruding ring is provided on the side wall of the door hinge, and a limiting rib is provided on the side wall of the installation space. The end face of the protruding ring can abut against the limiting rib to control the distance of the door hinge moving up and down.

[0010] In this embodiment of the utility model, a protruding post is arranged below the installation space, the lower end of the spring is sleeved on the outer periphery of the protruding post, the upper end of the spring is sleeved on the lower end of the door hinge, and the upper end of the spring can abut against the lower end face of the protruding ring.

[0011] This utility model also discloses another technical feature:

[0012] A storage cabinet includes the aforementioned door panel assembly and a cabinet body, wherein the door panel assembly is rotatably connected to the cabinet body.

[0013] In this embodiment of the utility model, the cabinet is provided with a plug hole, and one end of the door hinge can be inserted into and protrude from the plug hole. When the snap-fit ​​block is located inside the plug hole, the snap-fit ​​block abuts against the inner peripheral wall of the plug hole, which causes the elastic sheet to deform, so that the snap-fit ​​block retracts inward to allow the door hinge to pass through the plug hole. When the snap-fit ​​block is located outside the plug hole, the elastic sheet resets, causing the snap-fit ​​block to expand outward. The lower end face of the snap-fit ​​block can abut against the upper end face of the connecting hole, so that the door panel assembly and the cabinet can be rotatably connected together.

[0014] In this embodiment of the utility model, the insertion hole is a conical hole, the diameter of the conical hole on the side near the door hinge is larger than the diameter on the other side, one end of the door hinge is provided with a conical surface adapted to the conical hole, the snap-fit ​​block is configured to protrude from the conical surface, and the middle part of one end of the door hinge is provided with a clearance space to form when the elastic sheet deforms.

[0015] In this embodiment of the utility model, a notch is also included. When the door panel assembly is connected to the cabinet, the notch is configured to connect to the elastic sheet so that the elastic sheet can be driven to deform and the door hinge can be disassembled from the insertion hole, thereby realizing the separation of the door panel assembly from the cabinet.

[0016] In this embodiment of the present invention, a gap is formed between the through hole and the insertion hole in the axial direction, and a connecting ring is disposed in the gap. The connecting ring is located on the upper periphery of the through hole and is connected to the door panel assembly. The connecting ring is configured to fit the lower end face of the insertion hole. The side wall of the connecting ring is provided with the aforementioned notch. When the door panel assembly is in the closed state, the notch and / or window can be covered by the cabinet.

[0017] This utility model provides a door panel assembly and a storage cabinet, which has the following beneficial effects: First, by optimizing the door hinge structure and the design of the elastic plate, the problem of door panel sagging is effectively solved, improving the overall stability of the storage cabinet; Second, the door hinge is pre-installed in the door panel assembly, eliminating the need for additional accessories (such as door hinge covers), simplifying the assembly process and improving production efficiency; Third, the design of the elastic plate and the snap-fit ​​block improves the firmness of the connection between the door panel assembly and the cabinet body, significantly increasing the difficulty of accidental disassembly and intentional damage, ensuring that the door panel is not easily detached; Finally, the spring and the door hinge work concentrically, limiting the range of motion of the door hinge so that it can only move in the vertical direction, further improving the compactness and reliability of the assembly.

[0018] Specifically, when the locker is closed, the openings and windows are concealed by the cabinet body, preventing easy access by external tools and maintaining the locker's neat and aesthetically pleasing appearance. This design not only improves the user experience but also enhances the product's market competitiveness. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0028] Referring to the accompanying drawings, the storage cabinet includes a cabinet body 1 and a door panel assembly 3. A door frame 2 is provided on the cabinet body 1 for connection with the door panel assembly 3. The door panel assembly 3 consists of a door panel 4 and a door sub-panel 5, which are fixed together by fasteners, snap-fit ​​connections, or other means, forming an installation space 6 between them. The installation space 6 is located on the upper side of the door panel assembly 3. A through hole 7 is provided on the upper end of one side of the door sub-panel 5 (which connects to the door frame), and a window 8 is provided on the rear side wall, communicating with the installation space 6. The front side of the door sub-panel at the window is sealed by the door panel to form the installation space. A door hinge 9 is installed inside the door panel assembly 3, and the door hinge 9 is vertically movable within the installation space 6. One end of the door hinge 9 extends out of the installation space 6 through the through hole 7, and the other end is inserted into a insertion hole 17 on the cabinet body 1, thereby achieving a rotatable connection between the door panel assembly 3 and the cabinet body 1. Preferably, the insertion hole is located above and below the door frame.

[0029] The structural design of the door hinge 9 is one of the core features of this invention. One end of the door hinge 9 is provided with an elastic piece 10, which can fit tightly against the inner circumferential wall of the insertion hole, increasing the connection strength between the door hinge and the cabinet. Preferably, the elastic piece 10 protrudes outward to form a locking block 11. When the locking block is subjected to external force, such as during installation or disassembly, the elastic piece 10 deforms along with the locking block, causing the locking block 11 to retract inward, thereby reducing the outer contour dimension of the door hinge 9 at the locking block 11. This design allows the door hinge 9 to pass smoothly through the insertion hole 17. Under normal conditions, when the external force disappears, the elastic piece 10 returns to its original shape, and the locking block 11 expands outward and abuts against the upper circumferential surface of the insertion hole 17, ensuring a firm connection between the door panel assembly 3 and the cabinet 1. Furthermore, a clearance space 19 is formed in the middle of the door hinge 9 to provide sufficient room for the deformation of the elastic piece 10, preventing deformation from being hindered due to interference.

[0030] To facilitate the vertical movement of the door hinge 9, a handle 12 is provided on the periphery of the door hinge 9. This handle 12 is connected to the rear side wall of the door sub-panel 5 via a window 8. The handle can be a cylinder, and the window is a strip-shaped hole. The major diameter of the cylinder corresponds to the width of the strip-shaped hole, allowing the handle to move stably up and down within the window. When installing or removing the door panel assembly 3, the user can drive the door hinge 9 vertically by driving the handle 12. Specifically, a protruding ring 13 is provided on the periphery of the door hinge 9, and a limiting rib 14 is provided on the side wall of the installation space 6. The end face of the protruding ring 13 abuts against the limiting rib 14 to limit the vertical movement distance of the door hinge 9, preventing excessive movement that could lead to assembly failure. The limiting ribs can be arranged horizontally or vertically within the vertically distributed installation space, and the distance between the vertically distributed limiting ribs defines the movement range of the door hinge.

[0031] Furthermore, this invention includes a spring 15 within the installation space 6. One end of the spring 15 is fitted onto the protruding post 16 below the installation space 6, and the other end is fitted onto the lower end of the door hinge 9 and abuts against the lower end face of the protruding ring 13. The function of the spring 15 is to provide upward elastic support for the door hinge 9, ensuring that it maintains an upward tendency to move when no external force is applied. This design not only simplifies the installation process of the door hinge 9 but also improves the reliability of the connection between the door panel assembly 3 and the cabinet 1. Preferably, the spring, protruding post, through hole, insertion hole, and door hinge are coaxially configured.

[0032] The insertion hole 17 is a key component on the cabinet 1 used to mate with the door hinge 9. It is designed as a tapered hole, with the diameter on the side closer to the door hinge 9 being larger than the diameter on the other side. Preferably, there are two insertion holes, one upper and one lower. The upper insertion hole mates with the door hinge, and the lower insertion hole mates with the lower door hinge 23. The lower door hinge can be directly connected to the door hinge structure, or it can have only one tapered surface that matches the lower insertion hole. A boss 24 is provided above the lower door hinge, creating a gap between the lower edge of the door panel assembly and the door frame. Correspondingly, one end of the door hinge 9 also has a tapered surface 18 that matches the tapered hole. The locking block 11 can protrude from the tapered surface 18, forming two narrow slits on the tapered surface. The sidewall of the door hinge between the two slits forms an elastic element. When the door hinge 9 is inserted into the insertion hole 17, the locking block 11 abuts against the inner peripheral wall of the insertion hole 17, causing the elastic plate 10 to deform and the locking block 11 to retract inward, thereby reducing the outer contour size of the door hinge 9 so that it can pass smoothly through the insertion hole 17. When the door hinge 9 is fully inserted, the locking block 11 is located outside the insertion hole 17. At this time, the elastic plate 10 returns to its original shape, and the locking block 11 expands outward and abuts against the upper peripheral surface of the insertion hole 17, ensuring that the rotational connection between the door panel assembly 3 and the cabinet 1 is stable and reliable. At the same time, the taper of the tapered surface and the tapered hole are the same.

[0033] Furthermore, this invention also incorporates a notch 21 to enhance the anti-accidental disassembly capability of the door panel assembly 3. When the door panel assembly 3 is connected to the cabinet body 1, the notch 21 connects to the elastic plate 10. The user can use a tool to drive the elastic plate 10 to deform, thereby disassembling the door hinge 9 from the insertion hole 17, thus separating the door panel assembly 3 from the cabinet body 1. For example, the user can use a screwdriver to poke the elastic plate. To further enhance the stability and ease of installation of the storage cabinet, this invention provides a connecting ring 20 within the gap 22 formed axially between the through hole 7 and the insertion hole 17. The connecting ring 20 is located on the upper periphery of the through hole 7 and is connected to the door panel assembly 3. The notch 21 is provided on the side wall of the connecting ring 20. When the door panel assembly 3 is in the closed state, both the notch 21 and the window 8 are blocked by the cabinet body 1, preventing easy operation by external tools and ensuring that the door hinge cannot be easily disassembled from the insertion hole. The upper end of the connecting ring on the door sub-panel is recessed to form a U-shaped notch. When disassembling the door panel assembly, you can use a flathead screwdriver to poke the elastic piece, causing the snap block to deform towards the door hinge axis, thereby allowing the door hinge to move downwards and disassemble the door panel assembly.

[0034] The assembly process of door panel assembly 3 is as follows: S1, pre-install the door hinge 9 and spring 15 inside the door sub-panel 5; S2, connect and fit the door panel 4 and the door sub-panel 5 together to form a body containing the installation space 6, so that the door hinge 9 and spring 15 are installed in the installation space 6; S3, after assembling the cabinet 1 in the normal order, put the door frame 2 on top; S4, insert the lower door hinge into the lower insertion hole. Before assembling the door hinge into the upper insertion hole, press the door hinge 9 down with the handle 12 until the upper end of the door hinge 9 is compressed below the through hole; S5, after aligning the through hole 7 and the insertion hole 17, release the handle 12 so that the door hinge 9 moves upward under the action of the spring 15 and is inserted into the insertion hole 17 of the door frame 2, completing the assembly action.

[0035] Through the above technical solutions, this utility model achieves efficient assembly and high stability of the storage cabinet. The design of the door hinge 9 and the elastic plate 10 significantly improves the firmness of the connection between the door panel assembly 3 and the cabinet body 1, while simplifying the assembly process. The concentric cooperation between the spring 15 and the door hinge 9 restricts the range of motion of the door hinge 9, allowing it to move only in the vertical direction, thereby improving the compactness and reliability of the assembly. In addition, the notch 21 and the window 8 are covered by the cabinet body 1 when the door panel assembly 3 is closed, which not only enhances the ability to prevent accidental disassembly, but also maintains the neatness and aesthetics of the storage cabinet's appearance.
