Abstract

The utility model relates to a door with a concealed ventilation air passage. The door is characterized by comprising a door base, a movable door plate and two pairs of parallelogram mechanisms arranged at the upper and lower ends of the movable door plate, wherein a cavity is formed in the middle of the door base; the movable door plate can move in the cavity; the ventilation air passage is formed in a gap between the movable door plate and the door base; a shielding plate for obstructing visual lines is arranged on the back surface of the door base; and under the control of the parallelogram mechanisms, the movable door plate moves in the cavity of the door base parallelly, and the gap between the movable door plate and the door base can be controlled, namely air quantity can be controlled. The door has the advantages that: the ventilation air passage is formed by the gap between the door base and the movable door plate, all decoration effects can be reflected on the whole surface of the movable door plate, and the concealed ventilation air passage cannot be easily perceived by strangers. During ventilation, conditions in a room cannot be seen at any angle outside the door.

Description

A kind of door with hidden ventilating air passage

Technical field

The utility model relates to the facility in the building, especially about a kind of door that can ventilate.

Background technology

At present, known newly-built premises has no longer been made the transom window of door top.Sleep in evening or latent close thing need be shut door, then just no longer convection current of room air.Fresh air is difficult to be unfavorable for people's health in the inlet chamber.Industry for this reason utility model two kinds of air doors that have shutter: a kind of is on common door, to offer little shutter, and blinds is with certain oblique angle setting, can guarantee to ventilate and can not allow the stranger to see the situation of the indoor overwhelming majority.Another kind of then be common door adorn outdoors one as the lavatory door have blinds the door, can allowing air flow.But said two kinds of utility models have following shortcoming: the one, and people outdoors can see the situation (seeing Fig. 9 and Figure 10) in the room from certain angle.Next is that profile is indecency, and it is the lavatory that the existence of shutter can let the stranger take for this room.Also have a bit, if do not come round wind, but uncontrollable, said nothing of the size of control ventilation.Disclosed utility model patent document (patent No. CN200410052028.6) attempts to change said shortcoming, may stand on the stool but ignored the stranger, from half-open door top, sees indoor situation from top to down.And should technology use shutter, the yet size of uncontrollable ventilation is not so still solve the technical problem fully yet.

Disclosed utility model patent document (patent No. CN200910139992.5) changes above-mentioned prior art not enough (seeing Figure 11 and Figure 12); Set up decoration boss 9 in the front of common door; Be provided with the inside and outside cavity 91 of communication chamber in the boss, this cavity constitutes ventilating air passage; But it is dull that its weak point is a cam pattern, has only a small amount of pattern available, and the picture on surface of door is general the same with the picture of interior decoration as the important decorative cover of interior decoration, and it is selective to need multiple pattern.

Summary of the invention

In order to overcome the deficiency of prior art, the purpose of the utility model is from another angle such door to be provided: concealed with ventilating air passage, and can decorate any pattern on the surface of door.

The utility model is achieved in that

It comprises Men Ji, movable doorboard and is arranged on the movable doorboard two secondary parallel-crank mechanisms at two ends up and down; One end of first pole of parallel-crank mechanism is hinged with the door base; The other end and roller are hinged, and this roller can roll in the guide groove of movable doorboard, and an end and the movable doorboard of second pole of parallel-crank mechanism are hinged; The other end and roller are hinged, and this roller can roll in the guide groove of Men Ji; The middle part of first pole and second pole is hinged each other; Door base middle part is a cavity, and movable doorboard can move in cavity, and movable doorboard forms ventilating air passage with the gap of door base; The basic back side of door is provided with the shield of block vision;

Men Ji is provided with strut rail, and strut rail is provided with screw pair, and wherein an end of screw rod is connected on the movable doorboard, and rotating screw bolt moves movable doorboard, the size of control ventilating air passage.

Parallel-crank mechanism control under, movable doorboard is parallel move in the cavity of Men Ji, can control the gap length of movable doorboard and door base, just controls the size of ventilation.

The beneficial effect of the utility model is:

One, ventilating air passage is that gap by Men Ji and movable doorboard forms, and various decorative effects can be embodied on the monoblock face of movable doorboard, and looking does not almost have unusual part with conventional door, is difficult for letting the stranger perceive and has hidden ventilating air passage.

Two, can allowing air flow, also can stop circulation of air, also can control the size of ventilation.

Three, under the situation of ventilating, people outdoors can't see the situation in the room from any angle.

The specific embodiment

See Fig. 1-Fig. 5, the utility model is divided into a base 1 and movable doorboard 2 with door, two secondary parallel-crank mechanisms 3 is set two ends up and down at movable doorboard,

One end of first pole 31 of parallel-crank mechanism is hinged with door base 1; The other end and roller 4 hinged (seeing Fig. 1 and Fig. 7); This roller can roll in the guide groove 21 of movable doorboard; One end and the movable doorboard 2 of second pole 32 of parallel-crank mechanism are hinged, and the other end and roller 4 are hinged, and this roller can roll in the guide groove 11 of Men Ji; The middle part of first pole 31 and second pole 32 is hinged each other;

Basic 1 middle part of door is a cavity 19, and movable doorboard 2 can move in cavity 19, and movable doorboard forms ventilating air passage 12 (see figure 8)s with the gap of door base;

The basic back side of door is provided with the shield 15 of block vision; Visible from line 17, people outdoors can't see the situation in the door from any angle.

When the face 26 of movable doorboard overlapped with the face 16 of door base, ventilating air passage was closed.At this moment, indoor and outdoor is stuffy, also can play soundproof effect.

The strut rail 13 of door base is provided with screw pair 14, and wherein an end of screw rod 18 is connected on the movable doorboard 2, and rotating screw bolt 18 moves movable doorboard 2, the size of control ventilating air passage.The screw thread of screw rod 18 is a multiple thread, mainly is the characteristics of utilizing the multiple thread helical pitch long, can the fast moving movable doorboard.

The user needs only a rotating screw bolt 18 slightly, and under the control of parallel-crank mechanism 3, movable doorboard 2 is parallel moving in the cavity 19 of door base 1, can control a movable doorboard and the basic gap length of door, just controls the size of ventilation.
