Problems solved by technology

For example, the authorized announcement number is CN200985704Y, which discloses a silent and anti-collision invisible door closer, which includes an automatic door closing assembly and an opening and closing linkage assembly. The door leaf magnet and the door frame magnet at the relative position on one side of the door attract each other, and the opening and closing door linkage assembly includes a pair of door leaf magnetic oil cylinder and door frame magnetic push rod respectively installed on the side of the door leaf and the door frame away from the door leaf axis. It can play a very good mute and airtight effect, but its structure is complicated, the cost is high, and it is only suitable for use in public places, and it is not suitable for ordinary home decoration

Embodiment 1

[0029] As shown in the accompanying drawings, a silent, smoke-proof, and dust-proof door includes a door panel 1 and a door frame 5 matched with the door panel 1. The door frame 5 includes a door panel step 51 and a door frame base 52 arranged perpendicularly to each other; the door panel A protruding elastic sealing strip 512 is provided on the step surface 511 of the step 51 that is adjacent to the surface of the door panel 1 . A groove is disposed on the side of the step surface 511 close to the door frame base 52 , and the elastic sealing strip 512 is disposed in the groove. The elastic sealing strip 512 is a whole strip or a plurality of strips arranged evenly along the height direction of the door panel 1 from top to bottom. The elastic sealing strip 512 used in this embodiment is a rubber strip. The width of the elastic sealing strip 512 is 1 / 10 of the width of the step surface 511 . The side surface of the door panel 1 facing the direction of the door frame base 52 a...

Embodiment 2

[0032] The difference from the first embodiment above is that the width of the elastic sealing strip 512 is 1 / 3 of the width of the step surface 511 . The surface of the elastic sealing strip 512 facing the door panel 1 is a wave-shaped surface. The side surface of the door panel 1 facing the direction of the door frame base 52 and the surface of the door panel 1 facing the direction of the step surface 511 form an included angle of 92 degrees.

Embodiment 3

[0034] The difference from the above embodiments is that the width of the elastic sealing strip 512 is 1 / 5 of the width of the step surface 511 .

[0035] The door of the invention has the advantages of simple structure, small joints, convenient processing, low cost, and good mute, smoke-proof and dust-proof effects.

Abstract

The invention belongs to the field of doors, and in particular relates to a muting, smoke-proof and dustproof door which is low in cost and has good sealing and muting effects. The muting, smoke-proof and dustproof door comprises a door panel and a doorframe matched with the door panel, wherein the doorframe comprises a door panel blocking step and a doorframe base which are vertical to each other; and raised elastic sealing strips are arranged on the door panel blocking step and the blocking step surface which is attached to the surface of the door panel. A groove is formed on one side, which is close to the doorframe base, of the blocking step surface, and the elastic sealing strips are arranged in the groove. When the door is closed, the door panel directly collides with the elastic sealing strips which are firmly fixed, so that the noise generated by collision is effectively prevented, and the elastic sealing strips are closely attached to the door panel to achieve a good hermetic closure effect.

Description

technical field [0001] The invention belongs to the field of doors, and in particular relates to a mute, smoke-proof and dust-proof door with low cost and good sealing and mute effects. Background technique [0002] Our living environment is full of all kinds of doors. Ordinary door panels and door frames have poor airtightness and loud opening and closing noise. I believe everyone has had such an experience. When you accidentally close the door with force, you will be frightened by a bang. , or if there is dust or smoke outside or inside the house, smoke and dust will also enter the cracks in the door. There are many good quiet or dust-proof doors on the market today that utilize modern technology. For example, the authorized announcement number is CN200985704Y, which discloses a silent and anti-collision invisible door closer, which includes an automatic door closing assembly and an opening and closing linkage assembly. The door leaf magnet and the door frame magnet at t...
