DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] See also Figures 1 to 6 A silent and soundproof wooden door comprises a door cover 1, a soundproof door body 2 is rotatably mounted on the door cover 1, an observation window 4 is inlaid and mounted on the soundproof door body 2, and when the soundproof door body 2 is in a closed state, sound can be well isolated.

[0026] Preferably, the observation window 4 may be double-layer vacuum glass, which facilitates observation while ensuring the sound insulation effect of the entire device.

[0027] A first rotating rod 9 and a second rotating rod 11 are rotatably mounted inside the soundproof door body 2, a connecting ring 8 is fixedly mounted on one side of the first rotating rod 9, and a mounting plate 7 is fixedly mounted on the connecting ring 8;

[0028] A fixing plate 6 is fixedly installed on the soundproof door body 2, and a shielding cover 3 is fixedly installed between the fixing plate 6 and the mounting plate 7;

[0029] The shielding cover 3 is a fan-shaped structure (similar to the structure of a folding fan and an accordion cover). The shielding cover 3 is adapted to the size and shape of the observation window 4. By changing the angle between the fixing plate 6 and the mounting plate 7, the shielding area can be changed.

[0030] A rotating block 12 is fixedly mounted on the other end of the second rotating rod 11 , and the first rotating rod 9 and the second rotating rod 11 are fixedly connected via a connecting rod 10 .

[0031] When a person is inside the room, the rotating block 12 is rotated, and the rotation of the rotating block 12 is transmitted to the connecting ring 8 through the first rotating rod 9 and the second rotating rod 11, so that the mounting plate 7 rotates, driving the shielding cover 3 to move, and the shielding adjustment activity can also be performed inside the room.

[0032] The first rotating rod 9 and the second rotating rod 11 are both hollow structures. A sliding rod 14 is slidably installed inside the soundproof door body 2. A limiting wheel 15 is fixedly installed on one end of the sliding rod 14 away from the second rotating rod 11. A limiting ring 13 is fixedly installed inside the connecting ring 8, and the limiting wheel 15 is adapted to the limiting ring 13.

[0033] The teeth on the limiting wheel 15 can cooperate with the grooves on the limiting ring 13, so that the shielding cover 3 is stably in a fully open or fully closed state.

[0034] When the limiting wheel 15 is inside the limiting ring 13 , since the sliding rod 14 can only slide but not rotate, the connecting ring 8 cannot rotate, so that the area of ​​the shielding cover 3 shielding the observation window 4 remains stable.

[0035] The sliding rod 14 is located inside the first rotating rod 9 and the second rotating rod 11 , the axis of the sliding rod 14 is in the same straight line as the axis of the first rotating rod 9 and the second rotating rod 11 , and both ends of the sliding rod 14 are exposed from the connecting ring 8 and the rotating block 12 respectively.

[0036] When the mounting plate 7 needs to be rotated, when the operator is outside the room, the limiting wheel 15 can be separated from the limiting ring 13 by pulling out the sliding rod 14. When the operator is inside the room, the sliding rod 14 can be moved outward to separate the limiting wheel 15 from the limiting ring 13, thereby facilitating observation and adjustment activities.

[0037] It is worth noting that when the operator is inside the room and moves the sliding rod 14 outward, even if the limiting wheel 15 has been separated from the limiting ring 13, the tail end of the sliding rod 14 is always partially exposed from the rotating block 12.

[0038] A slider 16 is fixedly mounted on the sliding rod 14 , and a fixing bar 17 is fixedly mounted inside the soundproof door body 2 . The fixing bar 17 is provided with a sliding groove for the slider 16 to slide.

[0039] The fixing bar 17 and the connecting rod 10 are on the same plane. Since the rotation angle of the connecting rod 10 is relatively limited, the movement of the connecting rod 10 will not affect the fixing bar 17 and the sliding rod 14 during adjustment activities.

[0040] When the sliding rod 14 is moved, the slider 16 moves on the corresponding sliding groove. The existence of the sliding groove can ensure that the sliding rod 14 will only move in a straight line. On the other hand, the movement distance of the sliding rod 14 can be limited, which is convenient for controlling the movement distance of the limiting wheel 15.

[0041] A lifting frame 5 is fixedly mounted on the soundproof door body 2, and the lifting frame 5 is adapted to the mounting plate 7. The lifting frame 5 can support the mounting plate 7 when the shielding cover 3 is completely closed, thereby ensuring the stability of the closed state.

[0042] The workflow of the utility model is divided into two scenarios when the shielding cover 3 needs to be adjusted.

[0043] When a person is outside the room, the sliding rod 14 is pulled out to separate the limiting wheel 15 from the limiting ring 13. At this time, the mounting plate 7 is manually rotated, and the angle between the fixing plate 6 and the mounting plate 7 changes, so that the blocked area of ​​the observation window 4 can be changed, making it easier to observe the interior of the room.

[0044] At the same time, driven by the first rotating rod 9, the second rotating rod 11 and the connecting rod 10, the rotating block 12 will also rotate.

[0045] When the observation is completed or the observation window 4 needs to be fully exposed, the sliding rod 14 is reinserted to make the limiting wheel 15 contact the limiting ring 13, thereby making the mounting plate 7 stably maintained in a horizontal or approximately vertical state, so that the area of ​​the observation window 4 blocked by the shielding cover 3 remains stable.

[0046] When a person is inside the room, the sliding rod 14 moves outward, and the limiting wheel 15 can be separated from the limiting ring 13. Then the rotating block 12 is rotated, which can drive the mounting plate 7 to rotate, and the same adjustment effect can be achieved.

[0047] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
