[0026] See also Figures 1 to 4 As shown, the utility model is a refrigerator center beam structure, including a center beam body 1. The center beam body 1 is designed as a symmetrical structure and adopts PET or PCM color plate. The purpose is, first, to avoid the need for spraying the existing center beam. The use of color plate can reduce the factory's environmental protection investment and the cost of spraying line construction, simplify the production process, reduce the number of workers, improve production efficiency, and thus reduce the cost of parts; second, the use of a symmetrical structure allows the door to be exchanged left and right, while reducing the variety of materials and reducing material maintenance costs. The left and right interchangeable universal center beam can increase the batch purchase quantity and reduce the purchase cost.

[0027] A U-shaped mounting groove 2 is provided along the length direction of the center beam body 1, and the two ends of the mounting groove 2 are respectively fixedly connected to the U-shaped reinforcing plate 3, and the top end of the U-shaped reinforcing plate 3 is vertically provided with a flange portion 30 of an integrated structure; the reinforcing plate 3 in the present application can be made of galvanized sheet material to solve the problem of rust on the existing reinforcing plate 3; the reinforcing plate 3 is designed as a U-shaped plate with a flange portion 30, which can improve the strength of the reinforcing plate 3, increase the contact area between the reinforcing plate 3 and the foam layer of the box body, and improve the function of the reinforcing plate 3 to grasp the foam layer, so that the reinforcing plate 3 and the foam layer are better integrated, and the ability of the center beam body 1 to resist impact and deformation is improved.

[0028] In this specific embodiment, at least two riveted positioning bosses 4 are provided on the inner bottom wall of the installation groove 2, and the riveted positioning bosses 4 are inserted and connected with the riveted recessed grooves 31 opened on the installation surface of the reinforcing plate 3, wherein the riveted positioning bosses 4 and the riveted recessed grooves 31 are both provided with riveted holes, and rivets are used in the riveted holes to keep the reinforcing plate 3 positioned and fixed in the installation groove 2; during the installation process of the reinforcing plate 3, it is convenient to quickly position the reinforcing plate 3 in the installation position through the riveted positioning bosses 4, so as to facilitate riveting and fixing, so that the positioning and installation of the reinforcing plate 3 are convenient.

[0029] In this specific embodiment, the width of the mounting groove 2 is set to be consistent with the width of the reinforcing plate 3, and the length of the reinforcing plate 3 is greater than 100 mm; in order to make the reinforcing plate 3 fit and install on the center beam body 1, the length of the reinforcing plate 3 is designed to be greater than 100 mm, which can improve the strength of the reinforcing plate 3.

[0030] In this specific embodiment, a plurality of threaded holes 32 with flanges are provided on the mounting surface of the reinforcing plate 3, and a through hole corresponding to the threaded holes 32 is provided on the mounting surface of the mounting groove 2; during the installation of the center hinge, the plurality of threaded holes 32 can be compatible with a variety of center hinges for screw fixing, thereby solving the problem that the existing center beam body 1 is not compatible with a variety of center hinges, resulting in a large variety of center beam bodies 1 and easy misinstallation.

[0031] In this specific embodiment, aluminum foil is clamped between the mounting surface of the reinforcing plate 3 and the mounting surface of the mounting groove 2. During the installation of the reinforcing plate 3, the aluminum foil can be pre-pasted on the mounting surface of the mounting groove 2, and then the reinforcing plate 3 is positioned and riveted to facilitate sealing the installation positions of the rivet holes and the threaded holes 32, thereby solving the defect that leakage of the existing center beam body 1 is difficult to clean.

[0032] In this specific embodiment, a process hole 34 is opened on the ear arm or flange portion 30 of the reinforcing plate 3 to solve the problem that the existing center beam body 1 made of color plate material and the center beam made of spray material are easily installed incorrectly. During the operation, the manual operation only needs to observe whether there is a process hole 34 on the reinforcing plate 3 to determine whether the beam to be installed is the center beam body 1 made of color plate material.

[0033] In this specific embodiment, a clearance groove 33 is formed between the top of the reinforcing plate 3 and the flange portion 30; this solves the problem of interference between the reinforcing plate 3 and other components, allowing the screws of other parts to be as close to the edge as possible, preventing the defect of warping of other components.

[0034] It should be understood that the reinforcing plate 3 in the present application is a symmetrical installation structure, and the reinforcing plates 3 symmetrically installed at both ends have the same shape, specifications and dimensions. This reduces the types of reinforcing plates 3, reduces mold costs, and reduces procurement costs through large-scale production, thereby improving the installation efficiency of the reinforcing plates 3.

[0035] The utility model has the advantages of low cost, simple process, high production efficiency, exquisite appearance, and error-proofing of left and right interchangeability. It also has the great advantages of preventing wrong installation, rust, liquid leakage, high versatility, and high anti-deformation strength.
