Refrigerator door sealing strip capable of being disassembled and assembled

Abstract

The invention discloses a refrigerator door sealing strip capable of being disassembled and assembled. The refrigerator door sealing strip involves a door body and a box body, the side, close to the box body, of the door body is provided with an inserting groove, a bottom plate is arranged on the side wall, close to the box body, of the door body, an inserting block is arranged in the middle of the lower surface of the bottom plate, supporting strips are arranged on the upper surface of the bottom plate, a magnetic strip installation block is arranged at one ends of the supporting strips, oneend of the magnetic strip installation block is in contact with the box body, a magnetic strip is installed inside the magnetic strip installation block, a first air bag block is arranged on the sidewall of the magnetic strip installation block, a first air bag is installed inside the first air bag block, a second air bag block is arranged on the side wall of the first air bag block, a second airbag is arranged inside the second air bag block, and one end of the second air bag block is connected with the bottom plate. According to the refrigerator door sealing strip, the structure is simple,the design is novel, the anti-collision performance of the door sealing strip is excellent, the phenomenon that cracking and damage are generated at joints of four frame edges due to long-term door opening and closing collision is avoided, disassembling and assembling are convenient, the sealing performance is good, and the refrigerator door sealing strip is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of refrigerator door seals, in particular to a detachable refrigerator door seal. Background technique [0002] Existing refrigerator door seals are made of soft polyvinyl chloride (PVC) material through an extruder to extrude a strip-shaped rubber sleeve, cut to length, install a magnetic strip, and weld the rubber sleeve. Its shape is a square frame. The cross-section of the strip rubber sleeve is irregular and different frame-shaped. The upper part of the rubber sleeve is provided with a convex wedge for snapping into the edge groove of the refrigerator door along the length of the rubber sleeve. There is a rectangular cavity and several special-shaped cavities inside. ; The rectangular cavity is located on the upper outside of the cross section, and is used to place the magnetic strip, and the other special-shaped cavities are left empty. [0003] The existing magnetic strip installation process and rub...

AI Technical Summary

Problems solved by technology

[0003] The existing magnetic strip installation process and rubber sleeve welding process mainly rely on manual operation, with a low degree of automation. The four corner welds of the door seal are easy to crack due to the collision of the door opening and closing during use, resulting in the leakage of cold air in the box.
