Embodiment Construction

[0017] The technical scheme of the present invention will be described in further detail below in conjunction with accompanying drawing and embodiment:

[0018] Such as figure 1 As shown, this kind of sealing strip with double sealing effect includes a sealing strip base 6 and a sealing part 2. The sealing strip is a hollow structure made of elastic material. The section of the sealing strip along the center line is an equilateral pentagon One side of the sealing strip is used as the sealing strip base 6, and the bottom surface of the sealing strip base 6 is processed with a glue groove 7 for installing the sealing strip. At the intersection of the two sides on one side of the strip top 4, a protruding sealing lip 5 along the center line of the sealing strip is provided. The upper edge of the sealing lip 5 is lower than the top 4 of the sealing strip, and the sealing lip 5 faces The length of the outer protrusion is the same as the width of the side of the sealing strip. The...

Abstract

The invention discloses a sealing strip with a dual-sealing effect. The sealing strip comprises a sealing strip base portion (6) and a sealing portion (2). The sealing strip is characterized in that the section of the sealing strip along the center line is an equilateral pentagon. One side face of the sealing strip serves as the sealing strip base portion (6), and the top of the sealing strip baseportion (6) exactly faces a sealing strip top portion (4). A sealing lip edge (5) which is outwards convex along the center line of the sealing strip is arranged on the point of the intersection between the sealing strip base portion (6) and the two side faces of one side of the sealing strip top portion (4), and the upper edge of the sealing lip edge (5) is lower than the sealing strip top portion (4). The sealing strip can achieve the dual sealing. In addition, the sealing strip is of a special structure and can achieve the sealing in the process that sliding doors and windows are closed inthe double directions.

Description

technical field [0001] The invention relates to a sealing strip with double sealing effects, which belongs to the technical field of sealing. Background technique [0002] For the concave door and window structure, only designing a layer of sealing strips on the inside cannot completely block the accumulation of rainwater in the groove on the outside; It is very likely that due to the increased compression, the sealing strip will be seriously deformed and the reliability will be reduced. Contents of the invention [0003] The present invention is designed to provide a sealing strip with double sealing effect for the purpose of improving the sealing effect of the sealing structure. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] This kind of sealing strip with double sealing effect includes a sealing strip base 6 and a sealing part 2, and is characterized in that: the section of the sealing strip along the cent...
