Embodiment 1

[0021] As shown in the drawings, a high-mute door frame includes a door panel step 1 and a door frame base 2, the door panel step 1 includes a step surface 11 facing the door body, and the door frame base 2 includes a step surface 11 connected to the base surface 21, the connection angle between the step surface 11 and the base surface 21 is provided with a rubber buffer mute strip 3, and the end of the rubber buffer mute strip 3 away from the step surface 11 is provided with a protrusion There is a first buffer block 31, and a second buffer slope 32 is provided at a position corresponding to the connection angle between the step surface 11 and the base surface 21 of the rubber buffer sound-absorbing strip 3 . The included angle between the step surface 11 and the base surface 21 is 98 degrees. The raised height of the first buffer block 31 is 3 mm.

Embodiment 2

[0023] The difference from the above embodiment is that the included angle between the step surface 11 and the base surface 21 is 95 degrees. The raised height of the first buffer block 31 is 5 mm.

Embodiment 3

[0025] The difference from the above embodiment is that the included angle between the step surface 11 and the base surface 21 is 100 degrees. The raised height of the first buffer block 31 is 1 mm.

[0026] The first buffer block 31 can buffer the door body for the first time, and decelerate the door body for the first time. The second buffer slope 32 can make the door body perform a second buffer deceleration before hitting the step. As the body keeps closing, the thickness of the second buffer slope in contact with the door body becomes larger and larger, the buffering effect is more obvious, and the mute effect is better. Moreover, the extrusion of the door body by the first buffer block 31 and the second buffer slope 32 greatly enhances the sealing performance of the door, and the effects of smoke prevention, dust prevention and sound insulation are better.

Abstract

The invention belongs to the field of doors, and particularly relates to a high-silence door frame. The high-silence door frame comprises a door sheet blocking step and a door frame base; the door sheet blocking step comprises a blocking step face facing a door body; the door frame base comprises a base face connected with the blocking step face; a rubber buffer silence strip is arranged in the connecting angle of the blocking step face and the base face; a protruding first buffer block is arranged at one end, far away from the blocking step face, of the rubber buffer silence strip; a second buffer slope is arranged at a position, corresponding to the connecting angle of the blocking step face and the base face, on the rubber buffer silence strip. The first buffer block plays a role in buffering the door body for the first time; by the second buffer slope, before running into the blocking step face, the door body is buffered for the second time and is decelerated; the door frame is excellent in silence effect. Due to pressure of the first buffer block and the second buffer block to the door body, sealing performance of a door is greatly improved, and the effects of preventing smoke and dust and insulating sounds are better.

Description

technical field [0001] The invention belongs to the field of doors, and in particular relates to a high-mute door frame. Background technique [0002] Most of the existing household main door frames are hollow metal frames. When the door is directly hit on the door frame when the door is closed, there will be a lot of noise. Some existing door frames are also equipped with some square mute strips. In the actual use process , its mute effect is not particularly good. Contents of the invention [0003] The purpose of the present invention is to provide a high mute door frame to solve the above problems. [0004] Above-mentioned technical purpose of the present invention is achieved through the following technical solutions: [0005] A high-mute door frame, comprising a door panel step and a door frame base, the door panel step includes a step surface facing the door body, the door frame base includes a base surface connected to the step surface, the step surface A rubber ...
