Composite sealed glue strip

Abstract

The invention discloses a composite sealing rubber strip, which includes a sealing part and a connecting part arranged on one side of the sealing part. The sealing part is composed of a wear-resistant surface layer wrapped with a sponge layer. The top end of the connecting part is inserted Installed in the sealing part, the lower end of the connecting part is provided with a barb; the sealing part of this product is composed of a wear-resistant surface layer wrapped with a sponge layer, which not only has low production cost, but also has good sealing performance. The requirements of dustproof and noise isolation, etc., and the top of the connecting part is plugged and installed in the sealing part, this design effectively strengthens the installation strength of the connecting part of the sealing strip, so that it is easy to insert and connect in the installation groove. In addition, this The product is provided with a barb at the lower end of the connecting part, so that the product is not easy to loose after being inserted, so that it can be widely used in the installation of doors and windows.

Description

technical field [0001] The invention relates to a sealing structure, in particular to a sealing structure used on doors and windows. Background technique [0002] At present, most of the doors and windows used rely on their own rigid contact for waterproofing. Due to manufacturing errors, long service life, and the influence of internal and external forces such as temperature and collision, the door body and frame of the door and window are deformed, reducing the waterproof performance of the door and window. Especially in the southern region, large gusts of water and typhoons are often encountered, causing a large amount of indoor water ingress, causing unnecessary troubles to users; in addition, when the door body and door frame of the door and window are closed, the collision sound is very loud, Form a kind of noise pollution to the environment. [0003] In order to solve the above problems, people usually use screws to fix the sealing strip on the frame of the door and ...

Problems solved by technology

[0002] At present, most of the doors and windows used rely on their own rigid contact for waterproofing. Due to manufacturing errors, long service life, and the influence of internal and external forces such as temperature and collision, the door body and frame of the door and window are deformed, reducing the waterproof performance of the door and window. Especially in the southern region, large gusts of water and typhoons are often encountered, causing a large amount of indoor water ingress, causing unnecessary troubles to users; in addition, when the door body and door frame of the door and window are closed, the collision sound is very loud, Noise pollution to the environment

[0003] In order to solve the above problems, people usually use screws to fix the sealing strip on the frame of the door and window. The sealing strip is usually directly injection molded from a single material, but in order to make the product have a longer service life and not easy to wear, it is usually required to be sealed The hardness of the rubber strip is high, and in order to make the sealing rubber strip achieve the purpose of good anti-leakage effect, the hardness of the sealing rubber strip is required to be low, so as to form surface contact with the contact body. In order to meet the above two requirements, the material The requirements are very high, resulting in higher costs, so the development of a sealant strip that is easy to install and has a lower cost has been put on people's research agenda.
