The invention relates to the technical field of door gaskets, in particular to a soft and hard door gasket, and solves the problem of unstable sealing performance due to the fact that the deformationprocess of a door gasket is in a random state during occlusion in the prior art. The soft and hard door gasket comprises a door gasket body made of hard modified plastic, an I-shaped sealing end is arranged at one end of the door gasket body, the sealing end comprises two transverse sections made of the hard modified plastic, and a vertical section between the two transverse sections is made of soft modified plastic and is of an arc-shaped structure which is bent towards one side of the door gasket body; two arc-shaped linkage blocks which are symmetrically distributed and made of hard plasticare arranged between the two transverse sections and the vertical end; and a wavy anti-collision layer made of the soft modified plastic is arranged on the side face, deviating from the door gasket body, of the vertical section. According to the soft and hard door gasket, by means of the anti-collision layer, a stable deformation guiding process is achieved during meshing, and better sealing performance is achieved.
本发明涉及门封条技术领域,尤其涉及一种软硬门封条,解决了现有技术中的门封条因为在咬合时形变过程呈随机状态,导致密封性能不稳定的问题。一种软硬门封条,包括由硬质改性塑料制成的门封条本体,门封条本体的一端设有呈工字型的密封端,密封端包括由硬质改性塑料制成的两个横向段,两个横向段之间的竖向段由软性改制塑料制成的呈向门封条本体一侧弯曲的弧形结构,两个横向段与竖向端之间设有呈对称分布的由硬质塑料制成的两个呈弧形的联动块;竖向段背离门封条本体的一侧面设有由软性改制塑料制成的呈波浪形的防撞层。本发明通过防撞层在咬合时具有稳定的形变导向过程,具有更好的密封性。
