Description

Technical Field

[0001] The utility model relates to the field of cabinet door assembly, in particular to a door frame and a cabinet door. Background Art

[0002] The doors used in existing disinfection cabinets typically consist of a door frame and a door panel, which is secured to the door frame with screws. This assembly process inevitably involves aligning the screw holes between the door frame and the door panel. Due to the small size of the screw holes, this alignment process is time-consuming and labor-intensive, reducing door panel assembly efficiency. Utility Model Content

[0003] Based on this, it is necessary to provide a door frame and cabinet door to address the problem of low door panel assembly efficiency.

[0004] A door frame comprises two transverse beams, two longitudinal beams and a positioning plate;

[0005] Both ends of the crossbeam are provided with a first clip, and both ends of the longitudinal beam are provided with a first slot. The two longitudinal beams are arranged side by side and spaced apart, and the two crossbeams are arranged side by side and spaced apart between the two longitudinal beams, so that the two crossbeams and the two longitudinal beams form a positioning cavity, and the first clip is clipped into the corresponding first slot, and the positioning plate is fixed in the positioning cavity to limit the door panel in the opening direction of the positioning cavity.

[0006] The crossbeam of the present invention includes a first enclosure and a first limiting plate. The first enclosure is used to enclose and form the positioning cavity. The first limiting plate is located in the positioning cavity. The edge of the first limiting plate is fixed on the surface of the first enclosure so that the positioning plate fits with the first limiting plate.

[0007] The longitudinal beam of the present invention includes a second enclosure plate and a second limiting plate. The second enclosure plate is used to enclose and form the positioning cavity. The second limiting plate is located in the positioning cavity. The edge of the second limiting plate is fixed on the surface of the second enclosure plate so that the positioning plate and the second limiting plate fit together.

[0008] The edge of the positioning plate of the present invention contacts the first enclosure plate and the second enclosure plate at the same time.

[0009] In the present invention, the first clip is arranged on the first enclosure plate, and the first slot is arranged on the second limiting plate.

[0010] In the present invention, a second clip is further provided on the first enclosure plate, and a second slot is further provided on the longitudinal beam, and the second clip is clipped in the second slot.

[0011] The longitudinal beam of the present invention also includes a connecting plate and a third limiting plate, both of which are located in the positioning cavity, and the third limiting plate and the second enclosure plate are opposite and spaced apart, and both side edges of the connecting plate are respectively fixed on the third limiting plate and the second enclosure plate, and the second slot is located on the third limiting plate.

[0012] In the present invention, the second limiting plate and the connecting plate are arranged opposite to each other, and the third limiting plate is located between the second limiting plate and the connecting plate.

[0013] A cabinet door comprises the door frame and door panel, wherein the door panel is at least partially located in the positioning cavity, the edge of the door panel contacts the two transverse beams and the two longitudinal beams at the same time, and the door panel is attached to the positioning plate.

[0014] The door panel of the present invention is adhered to the positioning plate, or the door panel is fixed to the positioning plate by screws.

[0015] The beneficial effects of the utility model are:

[0016] The door panel can be adhered to the positioning plate or fixed to the positioning plate with screws to complete the assembly of the door panel on the door frame. When the door panel and positioning plate need to be fixed with screws, once the door panel enters the positioning cavity, the door panel can be positioned in the width and height directions of the door frame through two crossbeams and two longitudinal beams. At the same time, the door panel can also be positioned in the normal direction through the positioning plate. As a result, the door panel has only a single installation position on the door frame, thereby ensuring the alignment of the screw holes on the door panel and the screw holes on the positioning plate. Because the above-mentioned screw hole alignment method does not directly align smaller screw holes, it can reduce the difficulty and workload of aligning the screw holes, speeding up the assembly of screws and door panels.

[0031] Example:

[0032] This embodiment provides a cabinet door, including a door frame and a door panel 5 .

[0033] See also Figure 2 and Figure 3 The door frame of this embodiment includes two horizontal beams 1, two longitudinal beams 2, and a positioning plate 3. The horizontal beams 1 and longitudinal beams 2 are perpendicular to each other. The horizontal beams 1 extend in the width direction of the door frame, and the longitudinal beams 2 extend in the height direction of the door frame. The two longitudinal beams 2 are arranged side by side and spaced apart, and the two horizontal beams 1 are arranged side by side and spaced apart between the two longitudinal beams 2. Thus, the two horizontal beams 1 and the two longitudinal beams 2 enclose a positioning cavity 4.

[0034] See also Figure 6 , wherein both ends of the crossbeam 1 are provided with a first buckle 11, see Figure 5, both ends of the longitudinal beam 2 are provided with a first card slot 21. Accordingly, the door frame of this embodiment has four first buckles 11 and four first card slots 21, and the four first buckles 11 and the four first card slots 21 correspond one to one. Figure 4 The first buckle 11 can be snapped into the corresponding first slot 21 so that the end of the crossbeam 1 can be connected to the end of the longitudinal beam 2 to maintain the stability of the door frame structure.

[0035] See also Figure 2 The positioning plate 3 is fixed in the positioning cavity 4, and the opening directions of the positioning plate 3 and the positioning cavity 4 are substantially perpendicular. Figure 1 The door panel 5 is at least partially located within the positioning cavity 4, and at this time, the edge of the door panel 5 simultaneously contacts the two crossbeams 1 and the two longitudinal beams 2, thereby positioning the door panel 5 in both the width and height directions of the door frame. In addition, the door panel 5 is also attached to the positioning plate 3, thereby also positioning the door panel 5 in its normal direction, that is, the direction of the opening of the positioning cavity 4.

[0036] The door panel 5 can be adhered to the positioning plate 3 or fixed to the positioning plate 3 by screws. If the door panel 5 and the positioning plate 3 need to be fixed by screws, as long as the door panel 5 enters the positioning cavity 4 and is positioned by the positioning plate 3 and the positioning cavity 4, the screw holes on the door panel 5 and the screw holes on the positioning plate 3 can be aligned, thereby reducing the workload of aligning the screw holes and speeding up the assembly of the screws and the door panel 5.

[0037] See also Figure 5 and Figure 6 In this embodiment, the crossbeam 1 includes a first enclosure 12 and a first limiting plate 13, and the longitudinal beam 2 includes a second enclosure 22 and a second limiting plate 23, wherein the positioning cavity 4 is formed by two first enclosures 12 and two second enclosures 22. The first limiting plate 13 is substantially perpendicular to the first enclosure 12, and the edge of the first limiting plate 13 is fixed to the surface of the first enclosure 12. The second limiting plate 23 is substantially perpendicular to the second enclosure 22, and the edge of the second limiting plate 23 is fixed to the surface of the second enclosure 22. Since the first limiting plate 13 and the second limiting plate 23 are both located in the positioning cavity 4, the positioning plate 3 can be simultaneously attached to the first limiting plate 13 and the second limiting plate 23. Accordingly, the positioning plate 3 can be adhered and fixed to the first limiting plate 13 and the second limiting plate 23, or can be fixed to the first limiting plate 13 and the second limiting plate 23 by screws.

[0038] See also Figure 1 When the door panel 5 is located in the positioning cavity 4, the edge of the door panel 5 is attached to the first enclosure panel 12 and the second enclosure panel 22. Figure 2The edge of the positioning plate 3 contacts both the first and second panels 12, 22 at the same time, so that the positioning plate 3 has only one installation position within the positioning cavity 4. Therefore, when the positioning plate 3 needs to be fixed to the first and second limiting plates 13, 23 by screws, the positioning plate 3 only needs to enter the positioning cavity 4 to ensure that the screw holes on the positioning plate 3 can be aligned with the screw holes on the first and second limiting plates 13, 23, reducing the difficulty of screw hole alignment and improving the assembly speed of the positioning plate 3.

[0039] In this embodiment, the first buckle 11 is provided on the first enclosure plate 12 , and the first slot 21 is provided on the second limiting plate 23 .

[0040] In order to further increase the connection strength between the crossbeam 1 and the longitudinal beam 2, see Figure 6 The first panel 12 is further provided with a second buckle 14, see Figure 5 , a second slot 24 is also provided on the longitudinal beam 2, see Figure 4 The second buckle 14 is engaged with the second slot 24 .

[0041] For details, see Figure 5 In this embodiment, the longitudinal beam 2 further includes a connecting plate 25 and a third limiting plate 26. The connecting plate 25 and the third limiting plate 26 are also located within the positioning cavity 4. The connecting plate 25 is substantially perpendicular to the second enclosure 22, so that the second limiting plate 23 and the connecting plate 25 are disposed opposite each other. The third limiting plate 26 and the second enclosure 22 are disposed opposite each other and spaced apart. The two side edges of the connecting plate 25 are respectively fixed to the third limiting plate 26 and the second enclosure 22. The third limiting plate 26 is located between the second limiting plate 23 and the connecting plate 25, and the second retaining groove 24 is located on the third limiting plate 26.

[0042] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
