It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0043] The principle and structure of the present utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0044] The refrigerator door end cap is an important part of the refrigerator door, usually located at the upper or lower part of the refrigerator door, used to protect the refrigeration system and insulation layer inside the refrigerator, and also helps to enhance the overall aesthetics of the refrigerator. The refrigerator door end cap is usually made of materials such as plastic, metal or glass, among which plastic materials are widely used because of their advantages such as lightness, durability, easy processing and low cost. Materials such as metal and glass are used in certain specific cases because of their high strength, aesthetics and corrosion resistance. In the design and manufacturing process of the refrigerator door end cap, multiple factors need to be considered, such as the selection of materials, the rationality of the structure, the convenience of processing and installation, etc. At the same time, the refrigerator door end cap also needs to have certain waterproof, moisture-proof, corrosion-resistant and wear-resistant properties to ensure its stability and reliability in long-term use. At present, the refrigerator door end cap and the shaft sleeve 23 are fixed by screws and reinforcing iron on the market, and its disadvantages are: the reinforcing iron needs to be assembled in advance, and the back glue needs to be pasted and fixed in the end cap, and the manpower and material costs are high.

A shaft sleeve 23 is provided near the screw column 3 on the door end cover 1, and the shaft sleeve is integrally injection molded with the door end cover. The screw column 3 and the shaft sleeve 23 protrude toward the inner side of the door end cover 1, so that when the door end cover 1 is fixed to the refrigerator door, the protruding screw column 3 and the shaft sleeve 23 are hidden in the refrigerator door. Prevent the protrusion to the outside from affecting the opening and closing of the refrigerator door.

[0048] like Figure 7-9As shown, the door closer 2 is used in conjunction with the door end cover 1. The door closer 2 is provided with a mounting hole 21, and the position of the mounting hole 21 corresponds to the position of the screw column 3; the door closer 2 shaft is provided near the mounting hole 21, and the door closer 2 shaft can extend into the shaft sleeve 23 and be rotatably connected with the shaft sleeve 23. The door closer 2 is installed on the outside of the door end cover 1, so that the mounting hole 21 is aligned with the screw column 3, the door closer 2 shaft is rotatably connected with the shaft sleeve 23, and then the screw passes through the mounting hole 21 and is screwed into the screw column 3 for fixing.

[0049] The screw column 3 and the door end cover 1 are designed and processed as one piece, which solves the problem that the traditional installation method needs to assemble the reinforcing iron in advance and needs to stick the adhesive backing to fix it in the end cover, which has high labor and material costs.

[0050] like Figure 10-11 As shown, in a further embodiment, the refrigerator door end cover 1 device further comprises a reinforcing plate 5, on which a first fixing hole 51 corresponding to the door closer 2 axis and a second fixing hole 52 corresponding to the mounting hole 21 are provided.
