Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments.
As shown in fig. 1, 2 and 3, in the embodiment of the present utility model: the mine roadway air door comprises a door frame 110, a first door plate 120 and a second door plate 130, wherein the first door plate 120 and the second door plate 130 are both rotatably connected to the door frame 110, the midpoint of the joint of the first door plate 120 and the second door plate 130 is set as a point A, the first door plate 120 and the second door plate 130 are centrally symmetrical about the point A, and a rotating mechanism is arranged between the first door plate 120 and the second door plate 130;
the rotating mechanism comprises a first connecting piece 140, a second connecting piece 150 and a third connecting piece 160, the top end of the first door plate 120 is connected with the first connecting piece 140, the top end of the second door plate 130 is connected with the second connecting piece 150, the third connecting piece 160 is connected between the first connecting piece 140 and the second connecting piece 150 through a rotating shaft, and the rotating mechanism drives the second door plate 130 to rotate in the opposite direction when the first door plate 120 rotates.
In the above, when the damper is opened, the first door panel 120 rotates clockwise with the connection point with the door frame 110 as an axis, so as to drive the left ends of the first connecting piece 140 and the third connecting piece 160 to rotate synchronously, and the third connecting piece 160 moves rightwards in the rotating process, so as to push the second connecting piece 150 to move rightwards, at this moment, the second door panel 130 receives thrust and rotates anticlockwise with the connection point with the door frame 110 as an axis, so as to drive the second connecting piece 150 to rotate synchronously, and when the damper is closed, the first door panel 120 rotates anticlockwise and drives the second door panel 130 to rotate clockwise through the pulling of the third connecting piece 160, and when the connection point of the first door panel 120 and the second door panel 130 is attached, the damper is closed.
The junction of the first door panel 120 and the second door panel 130 is provided in a mutually matched inclined shape.
Through the above design, when the first door panel 120 and the second door panel 130 are closed, the gap at the connection thereof can be reduced.
The first connecting member 140 has an "L" shape, wherein one end is connected to the first door panel 120, and the other end is connected to the third connecting member 160.
Through the above design, when the first connector 140 rotates clockwise along with the first door panel 120, the third connector 160 can be gradually pushed to the right, so as to achieve the purpose of driving the second connector 150 and the second door panel 130 to rotate.
