Member can as needed make the present embodiment the modification of not creative contribution after reading this specification, but as long as at this
It is all protected by Patent Law in the right of invention.
Embodiment：
As shown in Figure 1, a kind of novel closed door and window structure, including：Framework 1；With the fan body 2 of 1 phase of framework assembly；Set on frame
1 side of body and the hinge 3 for being used to connect framework 1 and fan body 2；It is assemblied in electric pushrod 4 of the framework 1 far from 2 side of fan body；With
And it is set to the hold-down mechanism 5 of 2 side of fan body, electric pushrod 4 is compressed for pushing fan body 2 to be turned on and off with respect to framework 1
Mechanism 5 is assembled with 4 phase of electric pushrod, and opposite framework 1 is closed closely under the action of electric pushrod 4 for fan body 2, and framework 1 is adopted
It is welded with 10mmQ235 steel plate assembly, fan body 2 is molded using 4mmQ235 steel plate rollings, and four of framework 1 and fan body 2 turn
It is excessive that angle is all made of circular arc, and hinge 3 is heavy hinge 3, in addition to the weight that can bear fan body 2, moreover it is possible to rotate freely, flexibly open
It closes；When door and window, electric pushrod 4 stretches out, and drives 5 activity of hold-down mechanism so that fan body 2 is opened, electronic to push away when closing the doors and windows
Bar 4 is retracted, and fan body 2 is closed with respect to framework 1, and hold-down mechanism 5 is so that 2 tight closure of fan body in framework 1, reaches enclosed moisture-resistant
Effect.
As shown in Figs. 1-3, hold-down mechanism 5 includes：It is assemblied in the sliding block 51 of 4 output shaft one end of electric pushrod；Set on framework 1
Two offsides, it is set to the briquetting 52 of two avris adjacent with hinge 3 of framework 1；Company between sliding block 51 and briquetting 52
Bar assembly 53；Support column 54 set on 2 side of fan body；Straight pin for connecting link assembly 53, briquetting 52 and sliding block 51
55；And one end is connected to sliding block 51, the other end is connected to the tension spring 56 of fan body 2；Support column 54 is used to support briquetting 52, slides
Block 51 and link assembly 53,1 side of framework offer the compression skewed slot 57 for 52 inlay card of briquetting；Sliding block 51 is cross, and
Four direction is equipped with the kidney slot 511 penetrated for straight pin 55, and fan body 2 and the contact surface innermost insert of framework 1 have fluid sealant
Item 6.
In the present embodiment, framework 1 is uniformly arranged respectively along the both sides of the pushing direction of electric pushrod 4 there are two briquetting
52, when electric pushrod 4 stretches out, band movable slider 51 travels forward, and tension spring 56 is compressed at this time, and link assembly 53 is driven to move,
So that briquetting 52 is skidded off out of compression skewed slot 57 along inclined-plane, after briquetting 52 unclamps in place, fan body 2 is driven to outwardly open, it is electronic
4 stopping of push rod acts, and breakdown action is completed；When electric pushrod 4 bounces back, fan body 2 is driven back to close, fan body 2 is closed in place
Afterwards, electric pushrod 4 is retracted with movable slider 51 under the action of 56 pulling force of tension spring, and briquetting is driven by sliding block 51 and link assembly 53
52 along the compression for compressing skewed slot 57, and after compressing in place, electric pushrod 4 is stopped, and closes window action and completes, since briquetting 52 is uniform
It is located at 1 liang of avris of framework so that briquetting 52 plays uniform pulling force to the surrounding of fan body 2, then is closely closed by sealing joint strip 6
It closes in framework 1, so that the door and window has good moisture seal performance.And it is inclined-plane to compress skewed slot 57 so that briquetting
52 the more can press the more tight in compression skewed slot 57, and wherein sealing joint strip 6 further strengthens the seal between fan body 2 and framework 1, draws
For spring 56 for during ensureing that fan body 2 closes or opens, briquetting 52 remains heeling condition, support column 54 to sliding block 51 with
And briquetting 52 and link assembly 53 are played a supporting role, and straight pin 55 is equipped in support column 54 so that sliding block 51 and pressure
Block 52 and link assembly 53 can be rotated with support column 54 for shaft, and then realized and driven briquetting 52 to fan by electric pushrod 4
The operation that body 2 is compressed, and 52 head of briquetting is designed for spherical roller, 52 rotation portion of briquetting is inlaid with self-lubricating copper sheathing
521, self-lubricating copper sheathing 521 has wear-resisting, low noise, high intensity, advantage with long service life so that briquetting 52 is compressing skewed slot
It is more smoothly when being moved in 57.
As depicted in figs. 1 and 2, link assembly 53 includes：For connecting the first connecting rod 531 with side pressing block 52；Pass through branch
Dagger 54 is set to 2 side of fan body and is connected to the second connecting rod 532 of sliding block 51；And connection first connecting rod 531 and second connects
Third connecting rod 533 between bar 532；One end of second connecting rod 532 is connected to by straight pin 55 in kidney slot 511, the other end
It is connected with third connecting rod 533 by straight pin 55, electric pushrod 4 is slided with movable slider 51, drives second connecting rod 532 to support
Column 54 rotates for shaft so that third connecting rod 533, first connecting rod 531 and briquetting 52 turn with the rotation of second connecting rod 532
It is dynamic, so that briquetting 52 is compressing sliding in skewed slot 57, action is turned off or on realize fan body 2.
As shown in Fig. 2, forming the mounting base 512 connected for electric pushrod 4 on sliding block 51, mounting base 512 is pushed away with electronic
4 output end of bar is connected by pin 513, and in order to which electric pushrod 4 is repaired or replaced, while electric pushrod 4 is equipped with behaviour
Make remote controler, and convenient for being used in the higher occasion of airtight door window installation site.
Identical in order to solve the problems, such as, the embodiment of the present invention additionally provides a kind of novel closed door and window, including above-mentioned implementation
Novel closed door and window structure in example.
A kind of novel closed door and window structure provided by the invention and door and window, operation principle or process are as follows：It is pushed away when electronic
When bar 4 stretches out, band movable slider 51 travels forward, and tension spring 56 is compressed at this time, drives link assembly 53 to move, so that briquetting 52
It is skidded off from compressing in skewed slot 57 along inclined-plane, after briquetting 52 unclamps in place, fan body 2 is driven to outwardly open, electric pushrod 4 stops dynamic
Make, breakdown action is completed；When electric pushrod 4 bounces back, fan body 2 is driven back to close, after fan body 2 is closed in place, in tension spring 56
Electric pushrod 4 is retracted with movable slider 51 under the action of pulling force, drives briquetting 52 oblique along compressing by sliding block 51 and link assembly 53
The compression of slot 57, after compressing in place, electric pushrod 4 is stopped, and closes window action and completes, since 1 liang of avris of framework is uniformly arranged
There is briquetting 52 and compress skewed slot 57 so that briquetting 52 plays uniform pulling force to the surrounding of fan body 2, then tight by sealing joint strip 6
Close closes in framework 1, so that the door and window has good moisture seal performance.
