AI Technical Summary
The existing wooden door frame has poor mute effect, and the rubber strip is prone to aging and only one piece is set up. After a long time, the buffering, shock absorption and mute sound insulation effects are greatly reduced, and the rubber strip is prone to fall off, making maintenance and replacement complicated.
A double silent door frame structure is designed. By adding two closed frames to the existing door frame, combined with the partition grooves set on the closed frame, when the door leaf is closed, the contact position between the door leaf and the door frame forms a multiple snap fit method, which enhances the sound insulation function of the entire door body, and through structural optimization, the stability of the door frame is ensured.
Through the double clamping fitting method, the sound insulation effect of the door body is significantly enhanced, the silent weakening problem of aging of a single rubber strip is avoided, and the stability of the door frame is ensured through structural optimization, simplifying the maintenance and replacement process.

[0023] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated. Example
[0024] like Figures 1 to 3 As shown, a double silent door frame structure includes an outer frame 1. In order to realize the installation of the entire door frame on the wall of a house, a first mounting groove 11 is provided on the front end face of the outer frame 1, and a second mounting groove 32 is provided on the rear part of the second main body 300 for contact installation with the mounting part of the wall.
[0025] The outer frame 1 includes an outer frame body 100, and a first extension section 102 is provided at the rear side of the outer frame body 100; a first connection cavity 101 is formed between the first extension section 102 and the rear side of the outer frame body 100; and the first closed frame 2 is fixed in the first connection cavity 101. In this solution, the fixing method of the first closed frame 2 includes but is not limited to rivets, glue bonding, and other fixing methods.
[0026] The first closed frame 2 is built inside the outer frame 1, and the outer end surface of the first closed frame 2 is provided with a first partition groove 21; specifically, the first closed frame 2 includes a first main body 200, and the first protrusion 201 is integrally provided on the right side of the front end of the first main body 200; the first protrusion 201 is located in the first connecting cavity 101. The first partition groove 21 is located on the front end surface of the first main body 200. In this solution, in order to achieve a stable connection between the first closed frame 2 and the outer frame 1 and the second closed frame 3, a first connecting cavity 101 is provided to be embedded therewith.
[0027] The second closed frame 3 is built inside the first closed frame 2, and the outer end surface of the second closed frame 3 is provided with a second partition groove 31. The second closed frame 3 includes a second main body 300, and a second connecting cavity 301 is provided in the middle of the front end of the second main body 300; the second main body 300 is partially embedded in the second connecting cavity 301; a second protrusion 302 is provided on the right side of the front end of the second main body 300, and the second protrusion 302 is embedded in the first connecting cavity 101 and contacts the first protrusion 201. In this solution, the second partition groove 31 is located on the left side of the front end of the second main body 300.
[0028] By adding two closing frames to the existing door frame and combining the partition grooves set on the closing frames, when the door leaf is closed, the contact position between the door leaf and the door frame forms a multiple snap-fitting mode, thereby enhancing the sound insulation function of the entire door body. Specifically, during use, sealing strips or the same conventional accessories can be installed in the first partition groove 21 and the second partition groove 31 for shock absorption and noise enhancement. In this solution, a double snap-fitting is adopted, which further eliminates the gap between the edge of the door leaf and the door frame, and improves the sound insulation effect of the entire door body.
