Embodiment 2

[0028] Embodiment two, such as Figure 4 As shown, the cross-section of the elastic sealing part 1 can also adopt a semi-ellipse or ellipse shape, and the bottom of the cross-section is compositely connected with the connecting part 2 . During use, the area of ​​the sealing contact surface can be increased, so that the outer edge of the elastic sealing part is close to the crimping surface, forming better sealing and heat preservation effects.

Embodiment 3

[0029] Embodiment three, such as Figure 5 As shown, the cross section of the elastic sealing part 1 can adopt a trapezoidal shape with a narrow bottom and a wide top, and a notch 7 can also be provided at the upper end, and the bottom of the cross section is compositely connected with the connecting part 2 . During use, the area of ​​the sealing contact surface can be increased, so that the outer edge of the elastic sealing part is close to the crimping surface, forming better sealing and heat preservation effects.

Embodiment 4

[0030] Embodiment four, such as Figure 6 As shown, the cross-section of the elastic sealing part 1 can adopt a rectangle whose bottom width is equal to the width of the upper end, and a notch 7 can also be provided at the upper end, and the bottom of the cross-section is compositely connected with the connecting part 2 . During use, the area of ​​the sealing contact surface can be increased, so that the outer edge of the elastic sealing part is close to the crimping surface, forming better sealing and heat preservation effects.

Abstract

The invention provides a composite door and window sealing strip. The composite door and window sealing strip solves the problems that existing door and window sealing strips are poor in sealing performance and have poor a heat and sound insulation effect, the sealing performance under the low-temperature environment is reduced, and meanwhile right-angle corners are also seriously deformed. The composite door and window sealing strip comprises a connecting part used for being fixed in a door and window clamping groove and an elastic sealing part in composite connection with the connecting part, and the connecting part and the elastic sealing part are all strip-shaped sections; the composite door and window sealing strip is characterized in that the elastic sealing part is a solid thermoplastic elastomer, and the connecting part is strip-shaped thermoplastic plastic with a clamping end. According to the composite door and window sealing strip, through the improvement of the material andstructure of the sealing strip, the sealing, heat preservation and noise resistance performance is further improved, the service life is prolonged, and the low-temperature environment resistance is improved; the portions, at door and window corners, of the sealing strip can also be bent, so that the continuous sealing effect is achieved.

Description

technical field [0001] The invention relates to a door and window sealing component, in particular to a composite door and window sealing strip. Background technique [0002] At present, there are corresponding sealing devices on automobile doors and windows and building doors and windows, which can tightly seal the inside and outside of the doors and windows. This type of sealing device is mainly a strip-shaped sealing strip. The conventional sealing strip has a hollow cavity. It is rectangular or triangular. During use, with the help of the material and elasticity of the sealing strip itself, it deforms after being subjected to external pressure, shrinks into the cavity, compresses the contact surface, and seals the car windows and building doors and windows. Existing door and window sealing strips are mainly made of rubber or PVC, and have the following defects: high hardness and poor elasticity, which cannot achieve tight surface sealing, are not suitable for right-angle...
