Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
- 6 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of ventilation of the convenient sealing of underground ventilation
Window, including main casing 1, sealing plate 3, head rod 6, support spring 8, rotation gear 10 and hollow bore 12, on main casing 1
Grid through hole 2 is set, and main casing 1 is connected with the first rotation axis 4,3 bottom of sealing plate is internally provided with the first rotation axis
4, and the surface of sealing plate 3 is provided with and places groove 5, the length and width of sealing plate 3 is more than the length and width of grid through hole 2
Degree, and sealing plate 3 and the angular range of horizontal plane are 0-90 °, and the inclination of sealing plate 3 can be so adjusted according to actual conditions
Angle, so as to ensure optimal ventilation effect, places second connecting rod 13 that is internally provided with of groove 5, places groove 5 positioned at close
The centre position of sealing plate 3, and the length for placing groove 5 is more than the length of head rod 6, so when sealing plate 3 fully opens,
In it is horizontal positioned when, head rod 6 can be completely embedded into place groove 5 in, shadow will not be caused to the movement of sealing plate 3
Ring, head rod 6 is connected with 7 and second connecting rod 13 of rack, and the top of rack 7 is provided with fixinig plate 701, and fixinig plate
So it is to ensure that spirit can be carried out between rack 7 and head rod 6 to be flexibly connected between 701 and head rod 6
