Technical Field

The invention relates to the technical field of door seals, in particular to a soft and hard door seal.

Background

The door strip of paper used for sealing is installed and is used for buffering the door and close the striking and improve the common door body auxiliary product of sealing performance on the door, and its sealing performance not only receives the influence of product material, more directly receives the influence of product structure.

At present, most door strip of paper used for sealing can set up the anticollision layer that is used for buffering the striking at the tip, and when the door was closed, the mutual interlock of anticollision layer on two door bodies to this realizes sealed purpose, and anticollision layer easily takes place deformation, and at the interlock in-process, deformation state is random state usually, leads to sealing performance unstable, consequently, need further improve the door strip of paper used for sealing, has better sealed effect with the guarantee.

Disclosure of Invention

The invention aims to provide a soft and hard door seal strip, which solves the problem that the sealing performance of the door seal strip in the prior art is unstable because the deformation process is in a random state during occlusion.

In order to achieve the purpose, the soft and hard door seal provided by the invention comprises a door seal body made of hard modified plastics, wherein an I-shaped sealing end is arranged at one end of the door seal body, the sealing end comprises two transverse sections made of the hard modified plastics, a vertical section between the two transverse sections is of an arc structure which is made of the soft modified plastics and is bent towards one side of the door seal body, and two arc-shaped linkage blocks which are symmetrically distributed and made of the hard plastics are arranged between the two transverse sections and the vertical end;

the end part of the door seal body, which is positioned at one side of the sealing end, is provided with a fixed block made of hard modified plastics, and two sides of the end part of the fixed block, which faces the vertical section, are provided with cushion blocks made of soft modified plastics and respectively connected with the two linkage blocks;

and a wavy anti-collision layer made of soft modified plastic is arranged on one side surface of the vertical section, which is far away from the door seal body.

Preferably, the two end faces of the impact layer are respectively in contact with the two transverse sections.

Preferably, the middle part of the cushion block is provided with an oval through hole along the length direction.

Preferably, a connecting section made of flexible modified plastic is arranged between the door seal body and the sealing end.

The invention has the following beneficial effects:

the anticollision layer is receiving when the extrusion, and vertical section can be to sealing strip body one side bending, and at this moment, two horizontal sections can be close to each other to let the anticollision layer be tight trend of clamp, make the deformation on anticollision layer have the guidance quality, have better sealed effect.
