Blocking the door leaf of doorframe inner space, wherein door leaf is connected through the hinge on the medial surface of doorframe to pass through
Promotion door leaf is overturn to be opened, supply pedestrian or equipment to pass through, but after leaving because of pedestrian, forgets to close wind
Door, and causes Air escape branch to there are major safety risks, it is proposed that a kind of can the air door tool of Automatic-closing
Have very important significance.
[utility model content]
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, it is provided that a kind of can Automatic-closing
Air door, is utilized the contractility of spring to automatically reset, is also had by air door pedestrian, close air door in time, keep away
Exempt to cause Air escape branch, make ventilating system stable, reliable.
For achieving the above object, the utility model proposes a kind of can the air door of Automatic-closing, including doorframe,
Door head, main door leaf, hinge, pull bar fix seat, the first pull bar, the second pull bar and reset slide, described door
On frame, iron square hinge has a head, is provided with two main door leafs below described door head, and described main door leaf is symmetrical by hinge
The both sides being connected to doorframe, described doorframe is provided with pull bar and fixes seat, and described pull bar is fixed and is hinged with on seat
First pull bar, described first pull bar and one end chain connection of the second pull bar, the other end of described second pull bar
Being connected with reset slide, described reset slide is fixed on the top of main door leaf.
As preferably, described reset slide also includes that slide block, chute, spring and convex body, described slide block are positioned at
The inside of described reset slide, described slide block cross sectional shape is circular, and described slide block is provided with convex body, described
Convex body and second connecting rod chain connection, described slide block is fixed on one end of spring, and the other end of described spring is solid
It is scheduled on the top of the inside of reset slide, described reset slide offers chute.
As preferably, described convex body is inlaid in chute, and described convex body can move in chute.
As preferably, being provided with spring inside described reset slide, described spring is compressive state.
The beneficial effects of the utility model: compared with prior art, the one that this utility model provides can be automatic
The air door closed, owing to pedestrian is by, after air door, if forgetting to close in time air door, producing Air escape branch
Problem, by installing reset slide on the main door leaf of air door, is provided with compression spring, profit inside reset slide
The performance resetted with the compression of spring, pedestrian by after air door, spring reset drives the second pull bar, and second
Pull bar drives the first pull bar, fixes on seat owing to the first pull bar is fixed on pull bar, and main fan door is in the effect of pulling force
Lower realization closes so that after pedestrian is by air door, close air door in time, it is to avoid cause asking of Air escape branch
Topic, makes ventilating system stable, reliable.
Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.
[accompanying drawing explanation]
Fig. 1 is that this utility model is a kind of can the structural representation of air door of Automatic-closing；
Fig. 2 is that this utility model is a kind of can the structural representation of reset slide of air door of Automatic-closing.
[detailed description of the invention]
For making the purpose of this utility model, technical scheme and advantage of greater clarity, below by accompanying drawing and
Embodiment, is further elaborated to this utility model.However, it should be understood that tool described herein
