Abstract
A soundproof insulating automatic sealing device for doors and windows is characterized in that the device in a side groove of a door/window and a movable seal strip form a four-link mechanisms together with links; when the door/window opens, sealing is not required, the four-link mechanism is at the upper limit under the action of springs, the movable seal strip is hidden in the side groove, a largest gap forms between the door/widow and a door/window frame, and no sealing action produces; when the door/widow gradually closes, sealing is required, the movable seal strip is pushed by a contact to move down to the lower limit of the four-link mechanism, the movable seal strip extends out of the side groove, a smallest gap forms between the door/window and the door/window frame, and sealing is achieved.
Description
Affiliated technical field
The present invention relates to the sealing device in a kind of door and window periphery gap, especially can automatic-sealed.
Background technology
At present, known door and window sealing strip, major part is rubber seal, is fixed on door and window peripheral, is compressed and is reached sealing purpose by door and window and doorframe and window frame, poorly sealed, can leakage sound.Seal tight after, can cause again that weather strip is damaged fast or door and window push-and-pull is motionless, resistance is large.
Summary of the invention
In order to overcome poorly sealed that existing door and window sealing strip exists, or the deficiency that weather strip is soon damaged or door and window push-and-pull is motionless, resistance is large, the invention provides a kind of automatic sealing device.This automatic sealing device can not only automatic-sealed, and sealing performance is high, door and window moving resistance is little.
The technical solution adopted for the present invention to solve the technical problems is: be provided with groove at door and window peripheral, movable weather strip is housed in groove, groove and movable weather strip are unified into a movable quadric chain by connecting rod.Door and window is opened, and while not needing to seal, the back-moving spring of movable weather strip one end, pushes movable weather strip to upper limit position in groove; At this moment door and window and doorframe and window frame gap maximum.When door and window is closed, need to seal time, the contact of the movable weather strip other end, gradually contacts door frame-edge quadric chain is pushed to lower position, and at this moment gap minimum between door and window and doorframe and window frame, plays sealing effectiveness.Like this when door window, spring is shifted movable weather strip onto between upper limit position, door and window and doorframe and window frame gap and is become resistance large, that door and window does not bring because of weather strip while moving, while closing the doors and windows, contact is pushed into lower position by movable weather strip automatically, reaches sealing purpose.
The invention has the beneficial effects as follows: the door and window resistance of motion is little, automatic-sealed, good sealing effect, the life-span is long, simple in structure.
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is that door and window of the present invention is opened movable weather strip and is in upper limit position sectional drawing.
Fig. 2 is that door and window of the present invention is closed movable weather strip and is in lower position sectional drawing.
1. door and window lateral grooves in figure, 2. spring, 3. connecting rod, 4. movable weather strip, 5. contact, 6. doorframe and window frame.
The specific embodiment:
In Fig. 1, when movable weather strip (4) deadweight is born door and window and opened by connecting rod (3).Contact (5) does not have External Force Acting, movable weather strip (4) is pushed into upper limit position by spring (2), at this moment gap maximum between door and window lateral grooves (1) bottom and doorframe and window frame (6), because of without hermetic resistance, door and window motion is free and relaxed.
In Fig. 2, when door and window is closed gradually, contact (5) contacts doorframe and window frame gradually, spring (2) is compressed, movable weather strip (4) is pushed to lower position, at this moment door and window lateral grooves (1) bottom direct with doorframe and window frame (6) between gap minimum, reach sealing effectiveness.
Claims (2)
1. a tolerant noise-insulating warm-keeping door and window automatic sealing device, in door and window lateral grooves, is equipped with respectively spring, connecting rod, movable weather strip, contact.It is characterized in that: door and window lateral grooves, connecting rod, movable weather strip form movable quadric chain.
2. tolerant noise-insulating warm-keeping door and window automatic sealing device according to claim 1, is characterized in that: movable weather strip opens and closes.Produce motion by spring thrust and contact pressure, play automatic-sealed effect.
