Background

In industrial production, many processes require insulation from the outside air, and therefore have high requirements for a sealing structure. The sealing strip is a product which seals an object, is not easy to open, and has the effects of shock absorption, water resistance, sound insulation, heat insulation, dust prevention, fixation and the like. The sealing strip is made of various materials such as rubber, paper, metal, plastic and the like. It can be used for automobiles, doors and windows, cabinets, containers and the like. But in the actual use, it is relatively poor to door and window sealed effect, still leaves certain clearance after closing. In addition, the self-locking of opening and closing structure can not be realized to conventional sealing strip, and when receiving the exogenic action, the leakproofness easily suffers destruction.

In order to solve the defects of the prior art, people have long searched for and put forward various solutions. For example, the chinese patent document discloses a sealing strip [201320440298.9] that includes a connecting portion, a first lip, and a second lip. One end of the first lip edge and one end of the second lip edge are respectively connected with two ends of the connecting part, and the other ends of the first lip edge and the second lip edge are free ends. Wherein the difference between the lengths of the first and second lips is 0-5 mm.

The problem that the sealing effect of the sealing strip is poor is solved to a certain extent by the scheme, but the scheme still has a lot of insufficiencies, for example, when external force is received, the problem that the sealing performance is easy to damage and the like is solved.
