[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0022] Referring to Figures 1 to 4 , a convenient opening and closing air hatch cover, including cabin body 1, the top end of cabin body 1 is hinged with top cover 2, the surface of top cover 2 is provided with locking mechanism 3, because the specific structure and working principle of locking mechanism 3 are the prior art known to the staff in the field, and too much elaboration is not made here, the inner wall of cabin body 1 is fixedly connected with track 4, the inside of track 4 is slidably connected with sliding seat 5, the side of sliding seat 5 is fixedly connected with sliding rod 7, the outer surface of sliding seat 5 is hinged with pull rod 6, the upper inner wall of track 4 is rotatably connected with shaft 8, the lower surface of shaft 8 is fixedly connected with hook 9, the lower surface of hook 9 is inclined surface, the end of pull rod 6 away from sliding seat 5 is hinged in the middle of the lower surface of top cover 2, sliding rod 7 is slidably connected in the inside of track 4, the outer surface of sliding rod 7 is provided with groove 11, hook 9 is clamped in the inside of groove 11, the outer surface of shaft 8 is sleeved with torsional spring 10, one end of torsional spring 10 is fixedly connected on the outer surface of shaft 8, the other end of torsional spring 10 is fixedly connected on the inner wall of track 4;

[0023] Push top cover 2 upwards, top cover 2 is turned up and opened upwards, simultaneously, it will drive pull rod 6 to rotate, pull rod 6 synchronously drives sliding seat 5 to slide in the inside of track 4, along with the amplitude of top cover 2 opening increasing, sliding seat 5 slides upwards, until sliding rod 7 contacts hook 9, because the bottom of hook 9 is inclined design, so sliding rod 7 will push hook 9 to rotate around shaft 8, and extrude torsional spring 10, after sliding rod 7 is moved up to a certain position, torsional spring 10 rebounds and drives shaft 8 to rotate, thereby makes hook 9 to be clamped in groove 11, makes to limit and fix sliding seat 5, thereby reaches the effect of supporting top cover 2, avoids the situation of top cover 2 falling caused by forgetting to support, improves the safety.

[0024] Referring to Figure 2 , Figure 3 and Figure 5 , the bottom inner wall of track 4 is provided with oil cylinder 12, the top end of oil cylinder 12 movably penetrates plug rod 13, the outer surface of oil cylinder 12 is fixedly connected with oil pipe 14, the end of oil pipe 14 away from oil cylinder 12 is fixedly connected with bellows 15, the outer surface of bellows 15 is sleeved with spring 16, both ends of spring 16 are fixed on the outer surface of bellows 15.

[0025] When the top cover 2 is closed, the sliding seat 5 will collide with the top end of the plug rod 13, extruding the plug rod 13 to slide in the oil cylinder 12, thereby extruding the silicone oil to enter the corrugated pipe 15 through the oil pipe 14, and also stretching the spring 16, achieving the buffering effect, avoiding the situation that the edge is rolled up when the top cover 2 directly closes the cabin body 1.

[0026] When the top cover 2 is opened, the user first opens the locking mechanism, and then pushes the top cover 2 upwards, and the top cover 2 is turned upwards to open, and at the same time, the pull rod 6 is rotated, and the pull rod 6 synchronously drives the sliding seat 5 to slide in the inside of the track 4, and as the opening range of the top cover 2 increases, the sliding seat 5 slides upwards until the sliding rod 7 contacts the hook 9, and since the bottom of the hook 9 is designed to be inclined, the sliding rod 7 will push the hook 9 to rotate around the shaft rod 8 and extrude the torsional spring 10, and when the sliding rod 7 moves to a certain position, the torsional spring 10 rebounds to drive the shaft rod 8 to rotate, thereby making the hook 9 clamped in the groove 11, so as to limit and fix the sliding seat 5, thereby achieving the effect of supporting the top cover 2, avoiding the situation that the top cover 2 is dropped due to forgetting to support, and improving the safety, and when the top cover 2 is closed, the hook 9 is opened outward, and as the sliding seat 5 slides down, the sliding seat 5 will collide with the top end of the plug rod 13, extruding the plug rod 13 to slide in the oil cylinder 12, thereby extruding the silicone oil to enter the corrugated pipe 15 through the oil pipe 14, and also stretching the spring 16, achieving the buffering effect, avoiding the situation that the edge is rolled up when the top cover 2 directly closes the cabin body 1.

[0027] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
