The hatch cover body is installed inside the mounting frame, and the hatch cover body is connected to the mounting frame through a connecting shaft. A handwheel is arranged on the front surface of the hatch cover body, and a threaded rod penetrates through the inside of the hatch cover body. The threaded rod is connected to the handwheel, and a connecting rod is installed on the outer side of the other end of the threaded rod. A fixing block is connected to the outer wall of the connecting rod. A movable block is slidably connected to the upper part of the back surface of the hatch cover body, and first moving rods are abutted against both sides of the outer wall of the movable block. The first moving rods are slidably connected to the hatch cover body, and a chute is formed in the middle of the back surface of the hatch cover body. A second moving rod is slidably connected to the middle of the back surface of the hatch cover body, and a spring is connected to the sliding end of the second moving rod. The other end of the spring is connected to one side of the inner wall of the chute.
[0007] Preferably, a sealing ring is sleeved on the outer wall of the hatch cover body.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.
[0019] Refer to Figures 1-3, An inclined hatch cover, comprising a hatch cover body 1 and a mounting frame 5. The hatch cover body 1 is installed inside the mounting frame 5, and the hatch cover body 1 is connected to the mounting frame 5 through a connecting shaft 2. A sealing ring 3 is sleeved on the outer wall of the hatch cover body 1. By setting the sealing ring 3, it mainly enhances the sealing performance after the hatch cover body 1 is closed. A handwheel 4 is arranged on the front of the hatch cover body 1, and a threaded rod 6 penetrates through the inside of the hatch cover body 1. The threaded rod 6 is connected to the handwheel 4, and a connecting rod 7 is installed on the outer side of the other end of the threaded rod 6. A fixing block 8 is connected to the outer wall of the connecting rod 7. A movable block 9 is slidably connected above the back of the hatch cover body 1, and both sides of the outer wall of the movable block 9 are abutted against a first moving rod 10. The first moving rod 10 is slidably connected to the hatch cover body 1, and a chute 12 is opened in the middle of the back of the hatch cover body 1. A second moving rod 11 is slidably connected to the middle of the back of the hatch cover body 1, and a spring 13 is connected to the sliding end of the second moving rod 11. The second moving rod 11 is distributed on the movement track of the fixing block 8. The fixing block 8 rotates as the connecting rod 7 rotates, so as to be able to push the second moving rod 11 on the movement track, so that the second moving rod 11 and the connecting rod 7 are both horizontally abutted against the inside of the mounting frame 5, completing the closing work of the hatch cover body 1. The other end of the spring 13 is connected to one side of the inner wall of the chute 12;
[0020] The maximum distance between the connecting rod 7 and the hatch cover body 1 is 1 cm, and the connecting rod 7 forms a rotating structure with the hatch cover body 1 through the threaded rod 6. The threaded rod 6 is in threaded connection with the hatch cover body 1, so as to drive the connecting rod 7 to move closer to or away from the back of the hatch cover body 1. The fixing block 8 is in a triangular structure, and the fixing blocks 8 are distributed on both sides of the outer wall of the connecting rod 7 in a staggered manner. After the fixing block 8 rotates with the connecting rod 7, it can push the second moving rod 11, and one side of it is in a wedge shape, which is convenient for adjusting the moving distance of the second moving rod 11. The movable block 9 and the first moving rod 10 both form an elastic structure with the back of the hatch cover body 1 through elastic members. After the connecting rod 7 releases the abutment against the movable block 9, the movable block 9 and the first moving rod 10 can complete the reset work by themselves under the elastic action of the elastic members.
[0021] Working principle: When in use, first, the staff opens the hatch cover body 1. During this period, the staff manually rotates the handwheel 4, so that the connecting rod 7 rotates with the rotation of the threaded rod 6. Therefore, the fixed block 8 on the outer wall of the connecting rod 7 releases the abutting effect on the second moving rod 11, so that the second moving rod 11 is reset under the driving action of the spring 13 and no longer plugs into the inner side of the mounting frame 5. Then people pull the hatch cover body 1, and it rotates around the connecting shaft 2 until it is horizontal. Then continue to rotate the handwheel 4, which continues to drive the threaded rod 6 to rotate, so that the threaded rod 6 drives the connecting rod 7 to rotate until it is vertical, and the abutting work on the movable block 9 can be completed. Then the movable block 9 moves upward, and the movable block 9 pushes the first moving rods 10 on both sides to move toward both sides, which is convenient for abutting on the surface of the mounting frame 5, playing a role in supporting the hatch cover body 1, so that the inclined hatch cover will not close due to its own gravity and move downward.
[0022] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
