Description

Composite mute door

Technical Field

The invention relates to a door plate, in particular to a composite silent door.

Background

In the life, we can often use various doors, but many doors are all set towards the silence direction at present, people like quiet rest environment in the life, and the door plant is the carrier that isolated two spaces were used, but the door plant is when the preparation, can not with ground, accomplish complete sealed between the door frame, so can produce great gap in many times, because there are more gaps, so hardly reach the effect of real silence, people can only improve on the door plant material, but the effect is general, if set up joint strip in the gap, then can lead to the door plant to produce the friction noise when the switch door, consequently can only be as far as possible less gap, and can not really accomplish sealedly.

Disclosure of Invention

The composite mute door adopts a simple structure, can effectively realize sealing, does not have any friction sound when the door is opened and closed, and has the best mute effect of the door panel.

The invention is realized by the following technical scheme: a composite silent door comprises a door plate, a sealed air bag body is arranged in the door plate, an annular groove is arranged on the outer wall surface of the door plate in a surrounding manner, a hollow sealing strip is embedded in each surface of the annular groove, when the sealing strip is in a natural state, the outer wall surface of the air bag body is flush with the outer wall surface of the door panel, an air outlet pipe and an air return pipe are arranged on the air bag body and face each sealing strip, the other ends of the air outlet pipe and the air return pipe are connected and sealed, the air in the air bag body is extruded into the sealing strip by extruding the air bag body, a door handle is arranged outside the door plate, the inner side end of the door handle is arranged opposite to the air bag body, one end of the air bag body penetrates through the door plate and extends out of the door plate, the extending end of the sealing strip contacts with the inner side surface of the door handle, the inner side surface of the door handle extrudes the protruding end of the air bag body, and when the air bag body is extruded, all the sealing strips are inflated and bulge out of the outer side surface of the door panel.

As a preferable technical scheme, the outer diameter of the air outlet pipe is smaller than that of the air return pipe, and the air return pipe is provided with a one-way valve which can only return air and cannot give out air, so that when the air bag body is extruded by the door handle, the air can be given out by the air outlet pipe with a small outer diameter, and the door handle can be slowly reset to play a silencing effect.

As the preferred technical scheme, the gasbag body is the gasbag body that has elastic deformation resilience ability, the sealing strip is the elastic sealing strip that has deformation resilience ability, and the one end of each sealing strip all bonds on the bottom surface of annular groove.

As the preferred technical scheme, the air bag body comprises an air bag main body part and an extrusion convex part, a through hole is formed in the door plate, the extrusion convex part penetrates through the through hole and extends out of the door plate, and a sealed air storage cavity is formed in the whole air bag body.

Preferably, an arc-shaped concave part is arranged at the outer side end of the extrusion convex part, and when the door handle is reset, one end of the door handle extrudes the air bag body and is buckled in the arc-shaped concave part.

The invention has the beneficial effects that: according to the invention, only one improvement is needed to be carried out on the door panel, so that the door panel has a very good sealing effect, the sealing capability of the closed door panel is improved, the silencing effect of the door panel is further improved, and the structure is very simple.

Detailed Description

As shown in fig. 1, the composite silent door comprises a door panel 1, a sealed air bag body 8 is arranged in the door panel 1, an annular groove is arranged on the outer wall surface of the door panel 1 in a surrounding mode, a hollow sealing strip 2 is embedded into each surface of the annular groove, the sealing strip protrudes outwards in fig. 1, the door wrench is in a reset state, the air bag body can be extruded by the reset door handle to bulge the sealing strip, and the door body is in a closed state, so that the aim of silent sealing is fulfilled.

As shown in fig. 3, when the sealing strip 2 is in a natural state, the outer wall surface of the sealing strip is flush with the outer wall surface of the door panel 1, the door handle is in an open state, the door panel is opened at the moment, the gas in the sealing strip enters the air bag body again, the sealing strip retracts, the door panel can be normally opened at the moment, the sealing strip cannot be in contact friction with an external object, and the situation of noise is avoided;

as shown in fig. 2, an air outlet pipe 4 and an air return pipe 3 are arranged on the air bag body 8 and face each sealing strip 2, the other ends of the air outlet pipe 4 and the air return pipe 3 are connected and sealed, the air in the air bag body 8 is extruded into the sealing strips 2 by extruding the air bag body 8, a door handle 7 is arranged outside the door panel 1, the inner side end of the door handle 7 faces the air bag body 8, one end of the air bag body 8 penetrates through the door panel 1 and extends out of the door panel 1, the extending end of the air bag body contacts with the inner side surface of the door handle 7, the inner side surface of the door handle 7 extrudes the protruding end of the air bag body 8, and when the air bag body 8 is extruded, all the sealing strips 2 are inflated and.

Wherein, the external diameter of outlet duct 4 is less than the external diameter of muffler 3, the speed of giving vent to anger is less than the speed of returning the gas, all install a check valve 5 on the outlet duct 4, can extrude the gasbag body after the door handle is closed, make the internal gas of gasbag slowly extrude and enter into in the sealing strip, the sealing strip expands after admitting air, when giving vent to anger, only give vent to anger by the outlet duct and slowly extrude gas and enter into in the sealing strip, its purpose makes the door handle withdraw the back at the staff, can not reset fast, the door handle can contact with the gasbag body when resetting, then slowly extrude the gasbag body, slowly extrude the internal gas of gasbag in the sealing strip, its purpose plays the purpose of door handle silence, make the door handle put down back and convex gasbag body flexible contact, increase the silence effect, then slowly resume extrusion gasbag body, it is. And when the door handle was opened the back, the gasbag body lost the extrusion, was returned the gas by the muffler this moment for the gas in the sealing strip returns the gasbag internally fast, makes the sealing strip reset again, and the gasbag body resets, and the sealing strip can not contact with outside object this moment, also can not produce the condition of friction noise when the switch door yet, consequently withdraws sealed spacing power fast after pressing down the door wrench, also can not produce the friction contact sound when promoting the door yet.

In this embodiment, the airbag body 8 is the airbag body 8 with elastic deformation restorability, the sealing strip 2 is the elastic sealing strip with deformation restorability, one end of each sealing strip is bonded on the bottom surface of the annular groove, the airbag body 8 includes an airbag main body portion 81 and an extrusion convex portion 82, a through hole is provided on the door panel 1, the extrusion convex portion 82 passes through the through hole and extends out of the door panel 1, a sealed gas storage cavity is provided inside the entire airbag body 8, an arc-shaped concave portion 83 is provided at an outer side end of the extrusion convex portion 82, when the door handle is reset, one end of the door handle 7 extrudes the airbag body and buckles into the arc-shaped concave portion 83, as shown in fig. 4.
