Abstract
The utility model discloses a countercurrent self weight closing ventilating window, and relates to the field of ventilating windows. The problems such as the complex structure of a ventilating window and easy deformation of a countercurrent ventilating window under a coal mine currently are solved. The countercurrent self weight closing ventilating window comprises a window frame and a window shield. The inside of the window frame is provided with a first ventilating window opening and a second ventilating window opening, the top end of the first ventilating window opening is connected with a first wind shield through a hinge in a movable mode, and a first over opening prevention baffle which prevents the wind shield from being over opened is arranged on the inner side of the periphery of the first window opening. The top end of the second ventilating window opening is connected with a second wind shield through a hinge in a movable mode, and a second over opening prevention baffle which prevents the wind shield from being over opened is arranged on the inner side of periphery of the second ventilating window opening. The countercurrent self weight closing ventilating window is simple in structure, easy to manufacture and capable of blocking up reverse wind currents.
Description
Technical field
The utility model relates to a kind of vent window, is specifically related to a kind of adverse current deadweight locking vent window.
Background technology
Colliery Mine coal and Gas Outburst regulation, air duct, ditch and drag conveyor road etc. by the reverse throttle pier must be provided with reverse partition apparatus.The reverse throttle vent window has all been settled reverse partition apparatus under the coal mine at present, but existing countercurrent ventilating window is that the four directions is to opening, the upper end, lower end, the left side that are the countercurrent ventilating window are provided with verge board, during ventilation then each locational verge board be opened, then each locational verge board is closed and stop reverse distinguished and admirable in the time of against the wind, complex structure, technical requirements is higher; The verge board of the left and right and lower end of countercurrent ventilating window need to arrange anti-opening apparatus, loses if do not prevent can not in time closing when opening apparatus then easily causes the verge board of the left and right and lower end of countercurrent ventilating window to run into against the wind to stop reverse distinguished and admirable function; Simultaneously in use verge board is yielding, can not effectively stop reverse distinguished and admirablely after the four sides verge board closure of countercurrent ventilating window, needs often to change verge board, wastes time and energy, and also increases cost of production.
The utility model content
The purpose of this utility model is in order to overcome deficiency of the prior art, provides a kind of simple in structure, easy to manufacture and can in time block reverse distinguished and admirable adverse current deadweight locking vent window.
For achieving the above object, the utility model provides a kind of adverse current deadweight locking vent window to comprise window frame and verge board, be provided with ventilation window one and ventilation window two in the described window frame, the top of ventilation window one is flexibly connected by hinge and verge board one, and ventilation window one peripheral inboard is provided with and prevents that the anti-mistake that verge board is crossed out from opening baffle plate one; The top of ventilation window two is flexibly connected by hinge and verge board two, and ventilation window two peripheral inboards are provided with and prevent that the anti-mistake that verge board is crossed out from opening baffle plate two.
The top of described ventilation window one is flexibly connected by two hinges and verge board one, and the top of ventilation window two is flexibly connected by two hinges and verge board two.
The beneficial effects of the utility model: adverse current deadweight locking vent window of the present utility model has saved prevented opening apparatus, simple in structure, easy to manufacture; Run into reverse when distinguished and admirable adverse current deadweight locking vent window realize cutting off reverse distinguished and admirable function because of the timely autoshutdown verge board of self gravitation effect, effectively improve the ability that mine is combated a natural disaster; Verge board is not yielding, has prolonged application life widely, has reduced maintenance cost, has saved cost of production.
Below in conjunction with accompanying drawing adverse current deadweight locking vent window of the present utility model is described further.
Description of drawings
Front view when Fig. 1 is the utility model ventilation;
Fig. 2 is A-A cut-away view among the utility model Fig. 1;
Front view when Fig. 3 is the utility model contrary wind;
Fig. 4 is B-B cut-away view among the utility model Fig. 3.
Among the figure: 1, window frame, 2, verge board, 3, ventilation window one, 4, ventilation window two, 5, hinge, 6, verge board one, 7, prevented opening baffle plate one, 8, verge board two, 9, prevented opening baffle plate two.
The specific embodiment
As shown in Figure 1 and Figure 2, the adverse current deadweight locking vent window of present embodiment comprises window frame 1 and verge board 2, be provided with ventilation window 1 and ventilation window 24 in the window frame 1, the top of ventilation window 1 is flexibly connected by two hinges 5 and verge board 1, and ventilation window one 3 peripheral inboards are provided with and prevent that verge board 2 from crossing the anti-mistake of opening and opening baffle plate 1.
As shown in Figure 3, Figure 4, the top of ventilation window 24 is flexibly connected by two hinges 5 and verge board 28, and ventilation window 24 peripheral inboards are provided with and prevent that verge board 2 from crossing the anti-mistake of opening and opening baffle plate 29.
Thereby when verge board 2 run into reverse when distinguished and admirable because of self gravitation and reverse distinguished and admirable effect so that 2 times backwardnesss of verge board open baffle plate 1 near the anti-mistake of preventing opening apparatus on the window frame 1 and prevented opening baffle plate 28 and realize in time cutting off reverse distinguished and admirable function; When verge board 2 during normal the ventilation verge board 2 under forward distinguished and admirable effect, raised and guaranteed the air proper flow of down-hole.
Claims (2)
