Description

Technical Field

[0001] The present invention relates to the field of furniture, and in particular to a handle and a door structure. Background Art

[0002] Currently, furniture handles are typically secured to the outside of the door panel using screws. During use, the screws alone provide the handle's fastening force. After repeated door openings, the screws can become loose and easily fall off. Using screws to secure the handle to the door panel also increases the manufacturing process.

[0003] Some existing furniture products require ventilation, such as shoe cabinet doors, stove cabinet doors, and tatami mat doors. The common method for these applications is to install ventilation nets on the door panels, which affects the overall coordination of the product and increases the manufacturing process. Furthermore, the handles on existing furniture door panels do not have the function of closing the ventilation holes. Some ventilation handles only have the function of ventilation. During humid rainy weather, moisture can seep into the cabinet through the holes. Summary of the Invention

[0037] The present invention provides a handle and door structure to solve the problem of easy detachment of furniture handles in the prior art.

[0038] Example 1

[0039] like Figures 1 to 12 As shown, the handle includes an inner cover 10, which is arranged on the inner side of the door panel 50. Figure 6 and Figure 7 As shown, the inner cover body 10 includes a mounting portion A11, a stop portion A12, and a hand-pull portion 13. The mounting portion A11 is an annular structure, and the outer periphery of the mounting portion A11 is embedded in the mounting hole 51 of the door panel 50; the mounting portion A11 is provided with a stop portion A12 at one end facing the inner side of the door panel 50, and the stop portion A12 is in contact with the inner side surface of the door panel 50; the mounting portion A11 is provided with a hand-pull portion 13 at one end facing the outer side of the door panel 50, and the hand-pull portion 13 extends out from the mounting hole 51.

[0040] like Figure 6 and Figure 7 As shown, in this embodiment, in order to ensure that the outer periphery of the mounting portion A11 can be firmly embedded in the mounting hole 51 of the door panel 50, a plurality of protrusions B111 are provided on the outer peripheral surface of the mounting portion A11 along its axial direction. The plurality of protrusions B111 are distributed along the circumference of the mounting portion A11, and the protrusions B111 are in contact with the inner wall surface of the mounting hole 51.

[0041] like Figure 6 and Figure 7 As shown, in this embodiment, in order to prevent the inner cover body 10 from rotating under force during the pulling and closing process, a protruding column 121 is provided on the side of the stop part A12 facing the door panel 50. The protruding column 121 is symmetrically arranged and inserted into the corresponding positioning hole 52 on the door panel 50.

[0042] The inner cover 10 is arranged on the inner side of the door panel 50, and the mounting portion A11 of the inner cover 10 is embedded in the mounting hole 51 of the door panel 50, and the hand-pull portion 13 extends from the mounting hole 51. When the handle is pulled to open the door, the hand-pull portion 13 is arranged on the inner cover 10, and the direction of the force acting to pull the door is the same as the installation direction of the inner cover 10. Each time the door is pulled, the mounting portion A11 of the inner cover 10 is more tightly embedded in the mounting hole 51 of the door panel, making the handle less likely to fall off. At the same time, there is no need to use screws to fix the handle, which simplifies the process and does not require the use of tools during the installation process, thereby improving installation efficiency.

[0043] like Figures 1 to 5 As shown, the handle further includes an outer cover 30, which is disposed on the outer side of the door panel 50. Figure 8 and Figure 9As shown, the outer cover body 30 includes a mounting portion B31, a stop portion B32, and a shielding portion 33. The mounting portion B31 is an annular structure, and the outer periphery of the mounting portion B31 is embedded in the mounting hole 51 of the door panel 50; the mounting portion B31 is provided with a stop portion B32 at one end facing the outside of the door panel 50, and the stop portion B32 is in contact with the outer side surface of the door panel 50; the shielding portion 33 is provided on the inner side of the annular structure of the mounting portion B31, and a through hole 37 is formed between the shielding portion 33 and the inner peripheral surface of the mounting portion B31, and the hand-pull portion 13 extends from the through hole 37.

[0044] like Figure 8 and Figure 9 As shown, in order to ensure that the outer periphery of the mounting portion B31 can be firmly embedded in the mounting hole 51 of the door panel 50, a plurality of protrusions C311 are provided on the outer periphery of the mounting portion B31 along its axial direction. The plurality of protrusions C311 are distributed along the circumference of the mounting portion B31, and the protrusions B111 are in contact with the inner wall surface of the mounting hole 51.

[0045] like Figures 6 to 9 As shown, the mounting portion A11 and the mounting portion B31 are in a circular ring structure, and the shielding portion 33 is in a semicircular plate structure. The hand-pull portion 13 in this embodiment includes an arc plate 131, which is fixed to the end of the mounting portion A11 facing the outside of the door panel 50. An outer cover plate 132 and an inner cover plate 133 are provided on both axial sides of the arc plate 131. The arc plate 131, the outer cover plate 132, and the inner cover plate 133 form a hand-pull cavity of the hand-pull portion 13.

[0046] like Figure 8 and Figure 9 As shown, the arc outer surface of the shielding portion 33 is fitted with the inner surface of the mounting portion B, and a vent A34 is provided on the semicircular plate surface of the shielding portion 33; in this embodiment, an edge plate 38 is provided on the outer surface of the shielding portion 33, and the edge plate 38 is fitted with the inner surface of the mounting portion B.

[0047] like Figures 1 to 5 As shown, the handle also includes a breathable cover 20, as shown in FIG. Figure 10 and Figure 11As shown, the ventilation cover 20 is a circular plate-like structure. It is rotatably mounted within the mounting portion A11 and located on the side away from the handle portion 13. The ventilation cover 20 is provided with a ventilation hole B21 corresponding to the ventilation hole A34. Rotating the ventilation cover 20 can align the positions of the ventilation holes B21 and A34, thereby achieving ventilation for the furniture and allowing the handle to function as both an opening and closing handle and ventilation. During humid rainy weather, rotating the ventilation cover 20 can offset the ventilation holes B21 and A34, indirectly closing the ventilation holes A34 and preventing moisture from penetrating the cabinet body and causing mold and other problems. In dry weather, rotating the ventilation cover 20 can align the positions of the ventilation holes B21 and A34, indirectly opening the ventilation holes A34 and allowing air inside the cabinet to exchange with the outside air, thus facilitating the dissipation of odors within the cabinet.

[0048] In this embodiment, there are multiple air holes A34 and multiple air holes B21, which correspond one to one with the number of air holes A34.

[0049] like Figures 8 to 11 As shown, the central position of the breathable cover 20 is provided with a through hole 22, and the outer cover body 30 further includes a central column 35, which is provided on the shielding portion 33 and passes through the through hole 22. The central column 35 is a hollow structure, and a notch 351 is provided on the side wall of the central column 35. Figure 12 As shown, the handle also includes a fixing column 40, which is inserted into the center column 35. A flange 41 is provided at one end of the fixing column 40 away from the breathable cover 20. A plurality of protrusions A42 are provided on the outer surface of the fixing column 40 along its axial direction. The plurality of protrusions A42 are distributed along the circumference of the fixing column 40. The protrusions A42 are fitted with the inner wall surface of the through hole 22, and the protruding height of the protrusions A42 gradually increases in the direction approaching the flange 41.

[0050] When the fixing column 40 approaches the breathable cover 20, the protruding height of the raised portion A42 gradually increases in the direction approaching the flange 41, thereby stretching the center column 35 from the notch, increasing the outer diameter of the center column 35, and then squeezing the inner wall surface of the through hole 22, thereby increasing the resistance of the breathable cover 20 during rotation, and indirectly being able to adjust the tightness of the breathable cover 20 during rotation.

[0051] like Figures 8 to 11As shown, a positioning post 36 is provided on the side of the shielding portion 33 facing the vent cover 20. A positioning slot 23 is provided on the vent cover 20 at a position corresponding to the positioning post 36. When the vent cover 20 is rotated to the position where the vent hole A 34 and the vent hole B 21 align, the positioning post 36 is inserted into the positioning slot 23. A guide slot 24 is provided on the side of the vent cover 20 facing the positioning post. When the vent cover 20 rotates, the positioning post 36 moves within the guide slot 24. In this embodiment, to facilitate rotational adjustment of the vent cover 20, a knob plate 25 is provided on the side of the vent cover 20 away from the inner cover body 10. A rotation mark 26 indicating the rotation direction is also provided. A positioning mark 27 is provided to distinguish the rotational position of the vent cover 20.

[0052] Example 2

[0053] like Figures 13 to 15 As shown, the difference between this embodiment and embodiment 1 is that the number of the air hole B21 is one, and half of the air cover 20 are air holes B21. This solution can enhance the ventilation effect and reduce the manufacturing and installation accuracy of the air cover 20.
