Description

Technical Field

[0001] The utility model relates to the technical field of sealing devices, and particularly relates to a high-sealing strip. Background Art

[0002] A sealing strip is a product that seals something to make it not easy to open and plays roles such as shock absorption, waterproofing, sound insulation, heat insulation, dust prevention, and fixation. Sealing strips are made of various materials such as rubber, paper, metal, and plastic.

[0003] The published patent No. CN209180354U discloses a high-sealing strip, which can ensure and enhance the sealing effect, has high sealing performance; requires a small pre-tightening force when achieving the sealing effect; can also avoid cracking due to large local stress and affecting the performance of the refrigerator; and has a simple structure and is easy to install and connect. However, during the use of this sealing strip, during long-term use, it often causes the distance between the sealing strips to increase due to stretching, affecting the sealing effect. For this reason, we propose a high-sealing strip. Content of the Utility Model

[0004] Aiming at the problems in the prior art, the utility model provides a high-sealing strip.

[0005] The technical solution adopted by the utility model to solve its technical problems is a high-sealing strip, which includes a sealing groove. A sealing card slot is opened at the top end of the sealing groove, and a sealing strip main body is inserted into the inside of the sealing card slot. The top end of the sealing strip main body is fixedly connected to the middle of a sealing fitting strip, and the top end of the sealing fitting strip is fixedly connected to the bottom end of a first fixing strip;

[0006] The top surface of the top end of the sealing groove is fixedly connected with a top fitting strip, and the end of the sealing strip main body is fixedly connected with a friction fitting strip.

[0007] By adopting the above technical solution, first, the bottom fixing strip at the bottom end of the sealing groove is fixed to one end of the refrigerator door leaf, and then the first fixing strip at the top end of the sealing fitting strip is fixedly connected to the other side of the door leaf. During the process of opening the refrigerator door, when the sealing strip main body is inserted into the inside of the sealing card slot, the expansion joint contracts and the sealing strip main body deforms to insert into the sealing card slot. After being completely inserted, the reset sealing strip is reset to drive the whole sealing strip main body to return to its original state. After insertion, the friction fitting strip and the top fitting strip are respectively attached to the sealing strip main body and the sealing fitting strip, so that the sealing strip completely cuts off the interval area.

[0008] Specifically, a plurality of expansion joints are opened on the inner side wall of the sealing strip main body.

[0009] By adopting the above technical solution, a telescopic joint is used to provide a certain deformation space for the overall insertion of the sealing strip and facilitate subsequent resetting, so that the overall sealing strip can be conveniently retracted and reset to maintain good sealing performance.

[0010] Specifically, a bottom fixing strip is fixedly connected to the bottom end of the sealing groove.

[0011] By adopting the above technical solution, the sealing groove is fixed to one side wall through the bottom fixing strip.

[0012] Specifically, a reset sealing strip is fixedly connected to the side of the sealing strip body away from the telescopic joint.

[0013] By adopting the above technical solution, the reset sealing strip enables the sealing strip body to maintain the plugging sealing performance of the sealing strip within a certain service life.

[0014] Compared with the prior art, the present utility model has the following beneficial effects:

[0015] Through the design of the sealing groove, sealing clamping groove, sealing fitting strip, sealing strip body, telescopic joint, friction fitting strip, top fitting strip and reset sealing strip in the technical solution of the present application, first, the bottom fixing strip at the bottom end of the sealing groove is fixed to one end of the refrigerator door leaf, and then the first fixing strip at the top end of the sealing fitting strip is fixedly connected to the other side of the door leaf. During the process of opening the refrigerator door, when the sealing strip body is inserted into the sealing clamping groove, the telescopic joint contracts and the sealing strip body deforms to insert into the sealing clamping groove. After being completely inserted, the reset sealing strip is reset to drive the whole sealing strip body to return to its original state. After insertion, the friction fitting strip and the top fitting strip are respectively attached to the sealing strip body and the sealing fitting strip, so that the sealing strip completely separates the spaced area.
