[0036] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, but cannot be understood as limiting the present application.

[0037] Combine the following Figure 1-Figure 10 The box door according to the embodiment of the present application is described.

[0038] The door of the embodiment of the present application comprises a handle 1 and a door end cover 2. The handle 1 is connected to the door end cover 2, and a gripping space 29 for fingers to enter is defined between the handle 1 and the door end cover 2. The gripping space 29 is provided with a first opening on one side in the first direction. A limiting space 210 is provided on the door end cover 2, and the limiting space 210 is located on the side of the gripping space 29 away from the first opening in the first direction, and at least a part of the handle 1 fits in the limiting space 210.

[0039] According to the cabinet door of the embodiment of the present application, after the handle 1 is connected to the door body end cover 2, a gripping space 29 is formed between the two, and the user's fingers can be inserted into the gripping space 29 from the first opening to achieve gripping and pulling of the handle 1. Among them, by providing a limiting space 210 for at least part of the handle 1 to cooperate with on the door body end cover 2, and the limiting space 210 is located on the side of the gripping space 29 away from the first opening in the first direction, when the handle 1 is pulled, the handle 1 will press the inner wall surface of the limiting space 210, and the inner wall surface of the limiting space 210 further achieves support and limitation of the handle 1. Therefore, even if the handle 1 is a plastic extrusion part, it can effectively ensure that there is sufficient connection strength between the handle 1 and the door body end cover 2, and the handle 1 is not easily deformed when pulled.

[0040] It should be noted that the door end cover 2 is arranged at the upper end of the box door and extends in the horizontal direction. In the first direction, which is the height direction, the first opening is the upper end opening of the holding space 29.

[0041] For ease of understanding, Fig. 9 The direction indicated by the arrow Z is the first direction of the box according to the embodiment of the present application. Fig. 9The direction indicated by the arrow X is the second direction of the box according to the embodiment of the present application. Fig. 9 The direction indicated by the middle arrow Y is the third direction of the box according to the embodiment of the present application.

[0042] In some embodiments, Figure 6 As shown, the handle 1 is a plastic extrusion extending along the second direction, the second direction is perpendicular to the first direction, and the size of the limiting space 210 in the second direction is greater than or equal to the size of the holding space 29 in the second direction.

[0043] At this time, the outer surface of the handle 1 can be designed as a metal texture, which has a high aesthetic appearance and reduces the manufacturing cost of the handle 1. In addition, by setting the size of the limiting space 210 in the second direction to be greater than or equal to the size of the holding space 29 in the second direction, the contact area between the inner wall surface of the limiting space 210 and the handle 1 is larger, the supporting and limiting effect of the handle 1 is better, and the connection strength between the handle 1 and the door end cover 2 is higher, which effectively avoids defects such as flash seams caused by deformation of the handle 1.

[0044] Specifically, both the limiting space 210 and the holding space 29 extend along the second direction, and the size of the limiting space 210 in the second direction is greater than the size of the holding space 29 in the second direction.

[0045] In some embodiments, Figure 3 As shown, the door end cover 2 includes a partition 21 that separates the gripping space 29 from the limiting space 210 , and a first limiting groove 13 is provided on the side of the handle 1 facing the door end cover 2 , and the partition 21 fits in the first limiting groove 13 .

[0046] The cooperation between the partition plate 21 and the first limiting groove 13 effectively improves the positioning of the handle 1 on the door end cover 2, ensuring the installation accuracy of the handle 1 on the door end cover 2. At the same time, the cooperation between the two makes the connection between the handle 1 and the door end cover 2 tighter and more reliable.

[0047] Specifically, the first limiting groove 13 extends along the second direction and penetrates the handle 1. In order to improve the structural strength of the handle 1, a rectangular cavity extending along the second direction and penetrating the handle 1 is provided in the handle 1, and a reinforcing rib is provided in the cavity. The two ends of the reinforcing rib in the height direction are respectively connected to the upper and lower inner wall surfaces of the rectangular cavity, and the reinforcing rib divides the rectangular cavity into a first sub-cavity and a second sub-cavity arranged along the third direction (i.e., the front-back direction).

[0048] In some embodiments, the handle 1 includes a handle portion 11 and a first connecting portion 12 arranged along a first direction and extending along a second direction, and the second direction is perpendicular to the first direction. Both ends of the handle portion 11 in the second direction are connected to the door end cover 2, and a gripping space 29 is defined between the handle portion 11 and the door end cover 2. The first connecting portion 12 is connected to the door end cover 2 and fits in the limiting space 210.

[0049] That is, at least part of the connection points between the door end cover 2 and the handle 1 are located below the holding space 29. Combined with the design that the handle portion 11 is connected to the door end cover 2 at both ends in the second direction, the left and right sides and the bottom side of the handle 1 have connection points connected to the door end cover 2. Therefore, when the handle 1 is pulled, the inner wall surface of the limiting space 210 and the three connection points jointly support the handle 1, and the door end cover 2 has a higher support reliability for the handle 1.

[0050] In some embodiments, Figure 2 , Figure 3 , Figure 7 and Fig. 9 As shown, the handle portion 11 is provided with a limiting hole 111 extending along the second direction, the limiting hole 111 is a special-shaped hole, and the door end cover 2 is provided with a baffle 26 at one end in the second direction, and the baffle 26 is provided with a limiting member 27 extending along the second direction on the side facing the handle portion 11, the cross-sectional outer contour of the limiting member 27 matches the cross-sectional outer contour of the limiting hole 111, the limiting member 27 is clearance-fitted in the limiting hole 111, and the baffle 26 abuts against the handle portion 11.

[0051] During specific assembly, firstly, the limiting hole 111 of the handle 1 is sleeved on the door end cover 2 until the handle 11 abuts against the baffle 26, then the first connection part 12 of the handle 1 is inserted into the limiting space 210, and finally the first connection part 12 is connected to the door end cover 2 to complete the installation of the handle 1 on the door end cover 2. At this time, the cooperation between the limiting hole 111 and the limiting member 27, and the abutment between the handle 1 and the baffle 26, ensure that the door end cover 2 initially positions the handle 1 in the first direction and the third direction, and the installation accuracy of the handle 1 on the door end cover 2 is high.

[0052] Specifically, Figure 7 As shown, the cross-sectional outer contour of the limiting hole 111 is generally a combination of a triangle and a rectangle, and the limiting member 27 includes three rectangular blocks for guiding and limiting, and the length directions of the three rectangular blocks are angled with each other. The limiting hole 111 is a through hole that passes through the handle portion 11.

[0053] In some embodiments, Figure 4 and Fig. 9As shown, the limiting space 210 is provided with a second opening on one side of the third direction, and the third direction, the second direction and the first direction are perpendicular to each other. The door end cover 2 includes a plurality of guide ribs 28, which are arranged at intervals along the circumference of the limiting space 210 and form part of the inner wall surface of the limiting space 210. The thickness of the guide ribs 28 at the second opening gradually increases toward the bottom wall surface of the limiting space 210.

[0054] That is, the second opening of the limiting space 210 is expanded, which facilitates the insertion of the first connecting part 12 into the limiting space 210. The guide rib 28 is more likely to be slightly deformed after being compressed, so that the first connecting part 12 and the limiting space 210 are pressed against the guide rib 28 after being in place. The guide rib 28 effectively eliminates the assembly tolerance of the door end cover 2, thereby realizing reliable limitation of the first connecting part 12 in the first direction and the second direction.

[0055] Specifically, Fig. 9 As shown, the partition 21 and multiple guide ribs 28 together constitute a limiting space 210. After the first connecting portion 12 is engaged in the limiting space 210, it also abuts against the lower surface of the partition 21 and the bottom surface of the limiting space 210, thereby further increasing the contact area between the first connecting portion 12 and the door end cover 2.

[0056] In some embodiments, Figure 4 and Figure 5 As shown, the door end cover 2 includes an outer plate 22 and an inner rib plate 23 arranged in a first direction, and the inner surface of the outer plate 22 is provided with a convex strip 24 extending in the first direction, and the convex strip 24 and the inner rib plate 23 are arranged in a third direction at intervals, and the third direction, the second direction and the first direction are perpendicular to each other. The box door also includes a decorative cover 3, and the decorative cover 3 includes a limiting portion 31 and a second connecting portion 32 arranged in the first direction, and the side of the limiting portion 31 away from the second connecting portion 32 is provided with a first limiting groove 13, and the first limiting groove 13 extends in the second direction, and the convex strip 24 is fitted in the first limiting groove 13, and the second connecting portion 32 is connected to the inner rib plate 23.

[0057] During the specific installation, the limiting part 31 can be firstly sleeved on the convex strip 24 at the outer plate 22 through the first limiting groove 13, and then the second connecting part 32 can be driven to abut and connect with the inner rib plate 23, thereby completing the installation of the decorative cover 3 on the door end cover 2, and the installation of the decorative cover 3 is convenient.

[0058] Specifically, the decorative cover 3 is preferably a plastic extrusion, thereby ensuring that its outer surface has a metal texture while reducing its manufacturing cost. At this time, the decorative cover 3 extends along the second direction, and the first limiting groove 13 passes through the decorative cover 3 along the second direction. In addition, the outer plate 22 of the door end cover 2 is a horizontal top plate, and the inner rib plate 23 is generally a vertical plate connected to the outer plate 22 at the middle position in the third direction.

[0059] In some embodiments, Figure 5 As shown, a protrusion 25 is provided on the outer wall surface of the convex strip 24 , and in the first direction, at least a portion of the limiting portion 31 abuts against a surface of the protrusion 25 away from the second connecting portion 32 .

[0060] After the decorative cover 3 is connected to the door end cover 2, the upper surface of the limiting portion 31 is coplanar with the upper surface of the outer panel 22. At this time, when the decorative cover 3 is a plastic extrusion part with poor strength, the protrusion 25 realizes the upward support of the limiting portion 31, and effectively prevents the limiting portion 31 from deforming downward under the action of gravity and external force and generating a flash seam at the connection between the limiting portion 31 and the outer panel 22, thereby effectively ensuring the aesthetic appearance of the box door.

[0061] In some embodiments, Figure 1 and Fig.10 As shown, the second connecting portion 32 is located between the inner rib 23 and the handle portion 11 .

[0062] That is, the second connection portion 32 of the decorative cover 3 is hidden inside the handle portion 11 of the handle 1. At this time, the third fastener 6 used to connect the second connection portion 32 and the inner rib 23 is also hidden inside the handle portion 11, thereby effectively improving the appearance of the door at the handle 1.

[0063] In some embodiments, the handle portion 11 is connected to the inner rib plate 23 by clamping, bonding or a first fastener 4 at both ends in the second direction. And / or, the first connection portion 12 is connected to the inner rib plate 23 by clamping, bonding or a second fastener 5. And / or, the second connection portion 32 is connected to the inner rib plate 23 by clamping, bonding or a third fastener 6. In this way, the decorative cover 3 and the handle 1 can be reliably installed on the door end cover 2.

[0064] Specifically, the first fastener 4, the second fastener 5 and the third fastener 6 are all screws, which pass through both ends of the handle portion 11 and are threadedly connected to the inner rib plate 23. There are multiple screws passing through the handle portion 11 and are arranged at intervals along the second direction. The screw passes through the first connecting portion 12 and is threadedly connected to the inner rib plate 23. There are multiple screws passing through the first connecting portion 12 and are arranged at intervals along the second direction. The screw passes through the second connecting portion 32 and is threadedly connected to the inner rib plate 23. There are two screws passing through the second connecting portion 32 and are arranged at intervals along the second direction.
