Technical Field

[0001] The utility model relates to the technical field of sealing strips, in particular to a refrigerator sealing strip which is tightly connected and leak-proof. Background Art

[0002] The leak-proof refrigerator sealing strip is a rubber or silicone product with good sealing performance, which is used to prevent the cold air inside the refrigerator from leaking and the external heat from entering. It is usually installed between the refrigerator door and the cabinet to ensure that the refrigerator maintains a good sealing state during operation.

[0003] The installation of existing refrigerator sealing strips usually requires certain skills and experience. For people without installation experience, it may be difficult to replace the sealing strips by themselves. Once improperly installed, the refrigerator door may not close tightly. In addition, the existing refrigerator sealing strips are prone to accumulate dust and bacteria during use. If they are not cleaned and maintained regularly, the hygiene and sealing effect of the refrigerator may be affected. The gap of the existing refrigerator sealing strip structure is small, which is easy to hide dirt and grime, but it is not easy to clean.

[0004] Therefore, it is necessary to invent a refrigerator sealing strip that is tightly connected and leak-proof to solve the above problems. Utility Model Content

[0019] 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.

[0020] The utility model provides Figure 1-3A refrigerator sealing strip with tight connection and anti-leakage is shown, comprising a sealing strip 1. The overall structure of the sealing strip 1 is designed to provide good sealing performance to prevent the leakage of cold air inside the refrigerator and the entry of external heat. The sealing strip 1 is composed of four parts: a buffer part No. 1 2 and a buffer part No. 2 3, a leak-proof part 4 and a connecting part 5. This modular design allows the sealing strip to have high installation flexibility and maintenance convenience. The interiors of the buffer parts No. 1 2 and No. 2 3 are both hollow structures. The interior of the buffer part No. 1 2 is filled with a foam strip 6. The interior of the buffer part No. 2 3 is separated by a plurality of rubber strips. The hollow structure inside the buffer parts No. 1 2 and No. 2 3 and the filling of the foam strip 6 allow the sealing strip to have good elasticity and buffering performance, which can effectively absorb the impact force when the refrigerator door is closed and extend the service life of the sealing strip.

[0021] The leak-proof part 4 is L-shaped, located on the inner side of the back side of the sealing strip 1, and is used to engage with the raised part on the inner side of the refrigerator door panel. The connecting part 5 is T-shaped, located on the outer side of the back side of the sealing strip 1. The structural design of the leak-proof part 4 enhances the sealing effect of the connection with the refrigerator to prevent cold air leakage.

[0022] Furthermore, in the above technical solution, the foam strip 6 is made of polyurethane material, and the outer walls on both sides of the foam strip 6 are not completely tightly fitted with the inner walls on both sides of the No. 1 buffer part 2. The foam strip 6 made of polyurethane material has good wear resistance, corrosion resistance and aging resistance.

[0023] Furthermore, in the above technical solution, there is a certain gap between buffer part No. 1 2 and buffer part No. 2 3. This design allows the sealing strip to freely expand and contract during the closing process of the refrigerator door, thereby improving the sealing performance. Buffer part No. 1 2 is connected to the middle part of buffer part No. 2 3.

[0024] Furthermore, in the above technical solution, the front end of the connection part 5 is a solid rubber block, the rear end of the connection part 5 is a hollow structure, and the overall structure of the sealing strip 1 is made by one-piece molding. The one-piece molding process avoids the problems of loosening and falling off that may occur in the use of traditional sealing strips. This design of the connection part 5 makes the sealing strip easier to install and improves the sealing performance.

[0025] The utility model provides a refrigerator sealing strip that is tightly connected and leak-proof. When in use, its working process is as follows:

[0026] Preparation: Turn off the power of the refrigerator and make sure the refrigerator door is open. Prepare the new sealing strip and the required installation tools. Then remove the old sealing strip: Use a wrench or screwdriver to remove the old sealing strip from the gap between the refrigerator door and the cabinet, and be careful not to damage the refrigerator door and the cabinet during the removal process. Insert the No. 1 buffer 2 and No. 2 buffer 3 of the new sealing strip into the gap between the refrigerator door and the cabinet. Make sure that the position of the sealing strip is kept appropriate so that it is tightly connected to the contact surface of the refrigerator door and the cabinet. Insert one side of the notch of the leak-proof part 4 into the raised part on the inner side of the refrigerator door panel to ensure that the leak-proof part 4 fits tightly with the refrigerator door panel. Insert the T-shaped structure of the connecting part 5 into the gap between the refrigerator door and the cabinet to make it firmly connected with the other parts of the sealing strip 1. After the installation is completed, open the refrigerator door and observe whether the sealing strip fits tightly between the refrigerator door and the cabinet. Close the refrigerator door and press the sealing strip by hand to check its elasticity and buffering effect. If necessary, adjust the position of the sealing strip to ensure that it achieves a good sealing effect.

[0027] When the refrigerator is in operation, the No. 1 buffer part 2 and the No. 2 buffer part 3 of the sealing strip 1 can automatically adjust the buffering effect according to the opening and closing degree of the refrigerator door to prevent the refrigerator door from being subjected to excessive impact force. The leak-proof part 4 can fit tightly against the inner side of the refrigerator door panel to effectively prevent cold air leakage and external heat from entering. The connecting part 5 serves to fix the sealing strip 1 to ensure that the sealing strip 1 remains in a stable state during the entire use process. Since the material of the sealing strip 1 has good wear resistance and aging resistance, it can be used for a long time. And due to the structural design of the No. 1 buffer part 2 and the No. 2 buffer part 3 of the sealing strip 1, it is convenient to prevent dust and bacteria from accumulating inside the two, and it is convenient to clean and maintain regularly to maintain the sanitary condition and sealing effect of the refrigerator.

[0028] In short, the leak-proof refrigerator sealing strip effectively improves the sealing performance of the refrigerator, reduces cold air leakage, improves the energy utilization rate of the refrigerator, and ensures the sanitary condition inside the refrigerator through its unique design and materials.

[0029] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
