[0002] The magnetic sealing strip of the refrigerator is a sealing component installed on the edge of the refrigerator door. It is usually made of magnetic material. Its main function is to ensure that the refrigerator door can be closed tightly to maintain the low temperature environment inside the refrigerator, prevent cold air leakage, and save energy. At the same time, it can also effectively prevent external heat from entering the refrigerator and maintain the cooling effect inside the refrigerator.
[0003] Although the magnetic sealing strip of the refrigerator is very effective in maintaining the internal temperature of the refrigerator and preventing cold air leakage, in actual use, since the magnetic sealing strip is usually made of soft materials such as silicone, rubber, etc., it may wear, age, and crack after long-term use, resulting in a decrease in the sealing effect. As time goes by, the magnetism of the magnetic sealing strip may gradually weaken, affecting its adsorption force with the refrigerator body, and thus affecting the sealing effect.
[0004] Therefore, it is necessary to invent a magnetic sealing strip structure for a refrigerator to solve the above problems. Utility Model Content

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0024] The utility model provides Figure 1-6 A magnetic sealing strip structure for a refrigerator is shown, comprising a sealing strip 1, the sealing strip 1 ensures that the refrigerator door can be tightly closed, maintains a low temperature environment, prevents cold air leakage, saves energy, and maintains a cooling effect, the front of the sealing strip 1 is a pressure part 2, the pressure part 2 is provided with a groove 21 inside, a magnetic strip 24 is provided inside the groove 21, and a sealing frame 22 is provided around the inner side of the pressure part 2;
[0025] The back of the sealing strip 1 is a connecting part 3, and a placement groove 31 is opened on the back of the connecting part 3. Magnetic blocks 32 are embedded and installed at the four corners of the placement groove 31. The structural design of arranging magnetic blocks 32 at the four corners makes the sealing strip 1 and the refrigerator body have stronger adsorption force and extend the service life. A support bar 4 is vertically or horizontally arranged in the placement groove 31 and between every two magnetic blocks 32. Every two magnetic blocks 32 are connected by the support bar 4 to fix the position of the magnetic block 32 in the placement groove 31 on the back of the connecting part 3 to prevent the magnetic block 32 from falling.
[0026] Furthermore, in the above technical solution, the magnetic block 32 is an L-shaped structure, the support bar 4 is made of iron material, the support bar 4 is fixedly installed on the refrigerator, and the two ends of the support bar 4 are connected to the opposite ends of the corresponding two magnetic blocks 32.
[0027] Furthermore, in the above technical solution, convex strips 23 are fixedly installed on the outer walls of the sealing frame 22, and the convex strips 23 are used to resist the magnetic strips 24 in the grooves 21, and the sealing frame 22 seals the opening of the groove 21 of the pressure part 2 to prevent foreign matter, bacteria and water droplets from entering the grooves 21. The convex strips 23 are embedded and connected with the grooves 21 around the inner side of the sealing strip 1, and the sealing frame 22 and the convex strips 23 are both made of rubber.
[0028] Furthermore, in the above technical solution, the magnetic strip 24 is bonded to an inner wall of one side of the internal groove 21 of the pressure part 2, the outer edge of the magnetic strip 24 is in conflict with the edge of the convex strip 23, and sealant is applied at the connection between the sealing frame 22 and the pressure part 2, so that the sealing effect of the connection between the sealing frame 22 and the pressure part 2 is increased by the sealant.
