[0025] The door structure includes a frame 1, a panel 3 and a handle 2 with a hand-grip groove 21 at the front. The door structure of this embodiment only shows the panel 3, the frame 1 and the handle 2. Of course, it also includes other components for being rotatably connected to the box body. This part can refer to the existing technology and will not be repeated here.

[0026] The handle 2 is located at the front side of the frame plate 1. A shelf 11 is provided on the front wall of the frame plate 1 for the handle 2 to be placed thereon. A limiting strip 22 is provided at the bottom of the handle 2. An embedding groove 111 is provided on the surface of the shelf 11 for the limiting strip 22 to be embedded therein. Of course, it is also possible that the bottom of the handle 2 is provided with an embedding groove 111, and the surface of the shelf 11 is provided with a limiting strip 22 that can be embedded in the embedding groove 111. The cooperation between the embedding groove 111 and the limiting strip 22 can also limit the handle 2 in the front-rear direction, so that when the door is opened, a backward force is generated on the handle 2 to offset the lever force when the door is opened.

[0027] In this embodiment, the handle 2 extends in the left-right direction, and the embedding groove 111 and the limiting strip 22 both extend in the left-right direction.

[0028] The shelf 11 is arranged near the top of the frame 1, so that the handle 2 is at a higher position, and the user can touch the handle 2 and open the door without bending or bending too much. In addition, a plurality of ribs 211 for increasing friction resistance are arranged on the front wall surface of the hand grip groove 21 of the handle 2, and the ribs 211 extend in the left-right direction, and are used to increase the friction between the hand and the handle 2.

[0029] The panel 3 is attached to the front wall of the frame 1, and the panel 3 can be a glass panel 3. The top wall of the panel 3 is located above the table top of the shelf 11, so that the frame 1 will not be exposed and can be covered by the panel 3, further improving the aesthetics of the door structure. The part of the handle 2 placed on the shelf 11 is against the rear wall of the panel 3. Due to the cooperation of the embedded groove 111 and the limit strip 22 between the frame 1 and the handle 2, the bottom of the handle 2 will not have a tendency to move forward, so it will not generate force on the panel 3.

[0030] The handle 2 is connected to the frame plate 1 through a connecting piece. In this embodiment, a first connecting portion 23 is provided on the rear wall of the handle 2, a through hole 12 is provided on the frame plate 1 for the first connecting portion 23 to pass from front to back, and a second connecting portion 13 is provided on the rear wall of the frame plate 1.
