While these exemplary embodiments are described in sufficient detail to enable those skilled in the art to practice the utility model, it is to be understood that other embodiments may be realized and that various changes to the utility model may be made without departing from the spirit and scope of the utility model. The following more detailed description of the embodiments of the utility model is not intended to limit the scope of the utility model, as claimed, but is merely illustrative and not limiting of the utility model's features and characteristics in order to set forth the best mode of carrying out the utility model and to sufficiently enable those skilled in the art to practice the utility model. Accordingly, the scope of the utility model is limited only by the attached claims.
As shown in fig. 1-5, the utility model provides a sound insulation door frame, which comprises a side door pocket 1, wherein the side door pocket 1 is sleeved on a wall body 2 at a door opening, and is matched with a door plate 3 to seal the door opening. The side door pocket 1 comprises door pocket lines 11 fixed on two sides of the wall body 2, the door pocket lines 11 are fixed on two sides of the wall body 2, and the door pocket lines 11 vertically extend downwards to the floor along the wall body 2. The door pocket line 11 comprises a fixed plate and baking enamel, one side of the fixed plate is attached and fixed with the wall body 2, and the baking enamel is attached to the surface of the other side. One end of the door pocket line 11 extends inwards from the wall body 2 side to form a protruding part 12, and an opening 13 is formed in the middle of the protruding part 12. The door pocket line 11 includes a first pocket line 111 fixed to the wall body 2 on the closed side of the door panel 3, and a second pocket line 112 fixed to the opposite side of the first pocket line 111. One ends of the first and second sets of wires 111 and 112 each protrude from the wall 2 side. The first set of wires 111 extend less than the second set of wires 112. The ferrule 14 is secured to the protruding end portions of the first set of wires 111 and the second set of wires 112. The clamping sleeve 14 is clamped in the clamping groove 15 of the door pocket plate 4 to fix the door pocket plate 4.
The door pocket plate 4 is connected to the opening 13, and the door pocket plate 4 is fixed to the protruding portion 12 of the door pocket line 11 by a snap-fit manner. The door pocket plate 4 is equipped with the straight line wire casing near door plant 3 one side, and two right angle faces of straight line wire casing are fixed respectively first rubber strip 41 and second rubber strip 42. The first rubber strip 41 and the second rubber strip 42 extend vertically downward to the floor. In the closed state of the door panel 3, the first rubber strip 41 and the second rubber strip 42 are in contact with the door panel 3. In this state, the first rubber strip 41, the second rubber strip 42, the door pocket plate 4 and the door panel 3 are combined to form a first cavity 43. The sound wave passes through the sound insulation door frame and needs to pass through the first rubber strip 41, the first cavity 43 and the second rubber strip 42 in sequence, and part of vibration energy of the sound wave can be absorbed by the first rubber strip 41 and the second rubber strip 42 in the process; in addition, when the sound waves enter the first cavity 43, part of the sound waves are reflected back and forth between the first rubber strip 41 and the second rubber strip 42 in the first cavity 43, and the sound wave energy is again lost. Therefore, the sound insulation door frame can effectively reduce the penetration capacity of sound waves from the door gap and improve the sound insulation effect. The first cavity 43 serves to increase sound reflection to reduce noise and further improve the tightness of the wooden door and the door frame.
A gap 5 exists between the door pocket plate 4 and the wall body 2, and foaming glue 51 is filled at two sides of the gap 5. The boundary of the foam 51 is sealed with a third rubber strip 52 and a fourth rubber strip 53. The third rubber strip 52 and the fourth rubber strip 53 are fixed on one side of the door pocket plate 4, and the top ends of the third rubber strip and the fourth rubber strip are pressed against the wall body 2. The third rubber strip 52, the fourth rubber strip 53, the door pocket plate 4 and the wall body 2 together form a second cavity 54. The second cavity 54 has the same sound insulation principle as the first cavity 43, and mainly absorbs and dissipates sound waves penetrating from the door frame body, thereby improving the sound insulation effect. The second cavity 54 can enable the foaming glue 51 to form a bridge cut-off, cuts off a sound transmission path and effectively improves the sound insulation effect.
The door pocket plate 4 comprises a first pocket plate 44 and a second pocket plate 45, and the connection between the first pocket plate 44 and the second pocket plate 45 is provided with mutually matched clamping claws 46. The claws 46 on the first and second set of plates 44, 45 are snap-fit together. The first set of plates 44 and the second set of plates 45 are connected in a staggered manner such that the aforementioned right angle slot 47 is formed between the first set of plates 44 and the second set of plates 45. The first rubber strip 41 and the second rubber strip 42 are respectively connected to two right angle faces of the right angle wire groove 47. When the door panel 3 is closed, the outer right angle edge of the door is just pressed against the first rubber strip 41 and the second rubber strip 42 in the right angle edge groove to form a right angle wire groove 47.
And (3) sound insulation detection:
and a sound insulation door frame finished product is taken and installed on the door, a sound source is emitted in a room, and sound collection is carried out outside the room door. And a door frame sealed by a common rubber strip is taken, and collection, detection and comparison are carried out under the same condition.
Test results:
from the above test data, it can be seen that the inventive door frame has a significant improvement in sound insulation.
The utility model and its embodiments have been described above by way of illustration and not limitation, and the utility model is illustrated in the accompanying drawings and described in the drawings in which the actual structure is not limited thereto. Therefore, if one of ordinary skill in the art is informed by this disclosure, the structural mode and the embodiments similar to the technical scheme are not creatively designed without departing from the gist of the present utility model.
