Utility model content
In order to solve problem above, the utility model provides a kind of air door for mine, can by what must be installed on air door Form is replaced by a pressure relief window that can flexibly open, and can reach the effect of visual window, and and can reaches convenient and opens air door Purpose.
The technical solution of the utility model is as follows:A kind of air door for mine, is provided with visual window on the air door, it is described can The upper end of form is hinged on the window frame of air door, visual window automatic shutter component is provided with the air door, the visual window is certainly Dynamic shutter device includes the magnetic lock being arranged on window frame, in the adaptation opening position installation with magnetic lock of visual window There is locking plate, the locking plate is engaged with magnetic lock.
Technical solutions of the utility model also include:Spring seal strip, the elasticity are installed on the inner surface of the window frame Magnetic lock mounting hole is provided with sealing strip.
Technical solutions of the utility model also include:The flush of the magnetic lock and elastic sealing strip, the lock Stator is concordant with visual window edge.
Technical solutions of the utility model also include:The magnetic lock is permanent magnet, and the locking plate is magnetic material.
Technical solutions of the utility model also include:The magnetic lock is at least two in the same installation frame of window frame It is individual, interval between adjacent magnetic locking piece be present.
Technical solutions of the utility model also include:The visual window automatic shutter component includes electromagnetic locking circuit, described Magnetic lock is electromagnet, and the electromagnet is connected into electromagnetic locking circuit, and the locking plate is magnetic material.
Technical solutions of the utility model also include:The electromagnetic locking circuit includes the conducting block being arranged on window frame, institute State conducting block to electrically connect with electromagnet, the conductive number of blocks at least two is adjacent in the same installation frame of window frame Be provided with the interval that length is L between conducting block, the visual window to have length with the corresponding position of conductive block gap be L's Conductive bar.
Technical solutions of the utility model also include:Window handle is installed on the visual window.
The beneficial effects of the utility model are:A kind of air door for mine provided by the utility model, is let out using fluid communication Principle is pressed, air door visual window is changed to appropriately sized pressure relief window into, the upper end of pressure relief window is fixed on air door with folding, is easy to unload Window is pressed to open.
Influenceed by negative pressure, pressure relief window is usually in shutoff device;When needing pedestrian or being open to traffic, it need to only be opened lock is strengthened, Visual window is overcome the magneticaction between magnetic lock and locking plate visual window will be blown open, connects air door by suction function Inside and outside both sides, pressure difference is eliminated, so as to realize that the convenient of air door is opened, after pressure difference eliminates, visual window is gradually returned by Action of Gravity Field Fall, the magneticaction between magnetic lock and locking plate locks visual window, turns off reinforcement lock.
The air door can easily realize door opening, can realize the big air door of convenient unlatching negative pressure, facilitate pedestrian to drive a vehicle, The generation that air door squeezes the person's of hurting sb.'s feelings accident is avoided, improves the security of air door.Such air door is transformed on existing air door, Input cost is few.In addition, and not by air door set-point spacial influence, it is not necessary to the door opening device such as cylinder is installed, effectively section Spending is saved.
