Abstract

The invention relates to a door with a concealed ventilation air passage, and its special feature is that it includes a door base, a movable door panel and two pairs of parallelogram mechanisms arranged at the upper and lower ends of the movable door panel; the middle part of the door base is a cavity, and the movable door panel It can move in the cavity, and the gap between the movable door panel and the door base forms a ventilation air passage; the back of the door base is equipped with a shield to block the line of sight; under the control of the parallelogram mechanism, the movable door panel moves in the cavity of the door base, which can be controlled The size of the gap between the movable door panel and the door base is to control the amount of ventilation. The beneficial effect of the present invention is that: the ventilation air passage is formed by the gap between the door base and the movable door panel, and various decorative effects can be reflected on the entire surface of the movable door panel, making it difficult for outsiders to notice that there is a hidden ventilation air passage. In the ventilation, the situation inside the room cannot be seen from any angle outside the door.

Description

Doors with concealed ventilation channels

technical field

The present invention relates to facilities in buildings, in particular to a ventilating door.

Background technique

At present, in the known newly-built houses, the air window above the door is no longer made. If you need to close the door for sleeping or secret matters at night, the indoor air will no longer convect. It is difficult for fresh air to enter the room, which is not conducive to people's health. For this reason, the industry has invented two kinds of ventilation doors with louvers: one is that there are small louvers on the ordinary door, and the louvers are set at a certain oblique angle, which can ensure ventilation and prevent outsiders from seeing most of the indoor situation. . The other is to install a louvered door like a toilet door outside the ordinary door to allow air to circulate. But described two kinds of inventions have following shortcoming but: the one, the people outside the door can see the situation in the room from a certain angle (seeing Fig. 9 and Fig. 10). The second is the unsightly appearance. The presence of shutters will make outsiders mistakenly think that this room is a toilet. Another point is that if you don't want to ventilate, but you can't control it, let alone control the amount of ventilation. The published invention patent document (Patent No. CN200410052028.6) tries to change the above-mentioned shortcoming, but ignores that outsiders can stand on the stool and see the indoor situation from top to bottom from above the half-open door. And this technology has also used blinds, also can't control the size of ventilation, so still do not solve described technical problem fully.

The published invention patent document (patent number CN200910139992.5) changes the above-mentioned deficiencies in the prior art (see Figure 11 and Figure 12), and adds a decorative boss 9 on the front of the ordinary door. Cavity 91, which constitutes a ventilation airway; but its disadvantage is that the pattern of the boss is monotonous, and there are only a few patterns to choose from, and the surface pattern of the door is an important decorative surface of the interior decoration, which is generally the same as the painting of the interior decoration. , need to have a variety of patterns to choose from.

Contents of the invention

In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide such a door from another angle: the air duct is concealed, and any pattern can be decorated on the surface of the door.

The present invention is achieved like this:

It includes a door base, a movable door panel and two pairs of parallelogram mechanisms arranged at the upper and lower ends of the movable door panel; one end of the first pole of the parallelogram mechanism is hinged with the door base, and the other end is hinged with a roller, which can move in the direction of the movable door panel. Rolling in the groove, one end of the second pole of the parallelogram mechanism is hinged to the movable door panel, and the other end is hinged to the roller, which can roll in the guide groove of the door base; the middle parts of the first pole and the second pole are hinged to each other ;The middle part of the door base is a cavity, and the movable door panel can move in the cavity, and the gap between the movable door panel and the door base forms a ventilation air passage; the back of the door base is equipped with a shield to block the sight;

There is a crosspiece on the door base, and a screw pair on the crosspiece. One end of the screw rod is connected to the movable door panel. Turning the screw rod moves the movable door panel to control the size of the ventilation air passage.

Under the control of the parallelogram mechanism, the movable door panel moves in parallel in the cavity of the door base, which can control the size of the gap between the movable door panel and the door base, that is, the size of the ventilation volume.

The beneficial effects of the present invention are:

1. The ventilation air passage is formed by the gap between the door base and the movable door panel. Various decorative effects can be reflected on the entire surface of the movable door panel. It seems that there is almost no abnormality with the traditional door, and it is difficult for outsiders to detect hidden dangers. ventilation airway.

2. It can let the air circulate, can also block the air circulation, and can also control the amount of ventilation.

3. In the case of ventilation, people outside the door cannot see the situation in the room from any angle.

Detailed ways

As shown in Fig. 1-Fig. 5, the present invention divides the door into a door base 1 and a movable door panel 2, and two pairs of parallelogram mechanisms 3 are arranged at the upper and lower ends of the movable door panel,

One end of the first pole 31 of the parallelogram mechanism is hinged with the door base 1, and the other end is hinged with the roller 4 (see Figure 1 and Figure 7). The roller can roll in the guide groove 21 of the movable door panel. One end of the two poles 32 is hinged to the movable door panel 2, and the other end is hinged to the roller 4, which can roll in the guide groove 11 of the door base; the middle parts of the first pole 31 and the second pole 32 are hinged to each other;

The middle part of the door base 1 is a cavity 19, the movable door panel 2 can move in the cavity 19, and the gap between the movable door panel and the door base forms a ventilation air passage 12 (see Figure 8);

The back of the base of the door is provided with a shutter 15 that blocks the line of sight; it can be seen from the connection line 17 that people outside the door cannot see the situation inside the door from any angle. the

When the face 26 of the movable door panel coincided with the face 16 of the door base, the ventilation air passage was closed. At this time, there is no ventilation indoors and outdoors, and it can also play a sound insulation effect.

The crosspiece 13 of the door base is provided with a screw pair 14, wherein one end of the screw rod 18 is connected on the movable door panel 2, and the screw rod 18 is rotated to move the movable door panel 2 to control the size of the ventilation air passage. The screw thread of screw rod 18 is multi-start thread, mainly utilizes the feature that multi-start thread lead is long, can move movable door panel rapidly. the

As long as the user rotates the screw 18 a little, under the control of the parallelogram mechanism 3, the movable door panel 2 moves in parallel in the cavity 19 of the door base 1, and the gap between the movable door panel and the door base can be controlled, that is, the amount of ventilation can be controlled. .
