Plastic-strip door bottom seal strip capable of elastically opening and closing

Abstract

The invention discloses a plastic-strip door bottom seal strip capable of elastically opening and closing. The rubber-strip door bottom seal strip comprises a fixed plate (1), a rotating plate (2), a spring strip (3), a plastic strip (4), and a sill retainer (5). According to the rubber-strip door bottom seal strip, the fixed plate is provided with a hook pivot and a fixed plate groove; the rotating plate is provided with a rotating hook, a rotating plate groove, and a plastic plate groove; the sill retainer is a cylindrical plastic member; the plastic strip is fixedly connected to the lower edge of the rotating plate; the rotating hook of the rotating plate is inserted into the hook pivot and rotatably connected with the fixed plate; one end of the spring strip is inserted into the fixed plate groove and connected with the fixed plate by riveting; the other end of the spring strip is embedded into the rotating plate groove and connected with the rotating plate by riveting. When the rubber-strip door bottom seal strip is in use, the sill retainer is fixed to the lower portion of a door frame, and the fixed plate is fixedly connected to the bottom of a door leaf; the rotating plate tilts up and opens under the action of the spring strip, the plastic strip separates from the ground, and the door leaf is opened; the sill retainer contacts with the rotating plate and rotates down to close by overcoming elasticity of the spring strip, the plastic strip is in closed contact with the ground, and the door leaf is closed. Therefore, the rubber-strip door bottom seal strip is applicable to fitly contact with the grounds with any smoothness.

Description

technical field [0001] The invention relates to a door bottom sealing device, specifically refers to a rubber plate type door bottom which is installed at the bottom of the door leaf and is used to prevent outdoor sandstorms and insects from entering the room through the bottom seam of the door and does not hinder the door leaf from opening and closing freely. sealing strip. Background technique [0002] There are two types of door bottom sealing strips: rubber plate type and brush type. In the prior art, the rubber plate type door bottom sealing strip is fixed at the bottom of the door through strips. Because the ground is not flat enough, and the bottom surface of the door is not parallel to the ground, it causes The rubber plate and the ground of the rubber plate type door bottom sealing strip are either too tight to scrape the ground, hindering the door leaf from opening and closing freely; or there is a gap between the too loose and the ground, which loses the function ...

[0002] There are two types of door bottom sealing strips: rubber plate type and brush type. In the prior art, the rubber plate type door bottom sealing strip is fixed at the bottom of the door through strips. Because the ground is not flat enough, and the bottom surface of the door is not parallel to the ground, it causes The rubber plate and the ground of the rubber plate type door bottom sealing strip are either too tight to scrape the ground, hindering the door leaf from opening and closing freely; or there is a gap between the too loose and the ground, which loses the function of effectively preventing outdoor sandstorms and insects from entering the room; therefore, the prior art There are problems and deficiencies that it is difficult to make close contact with the ground with different flatness
