[0020] The door frame 1 and the outer wall of one side of the damper body 12 are both installed with support columns 14, and the cylinder body 15 is rotatably installed between the support columns 14. During the extension and retraction process of the cylinder body 15, the damper body 12 is controlled to open and close in cooperation with the support columns 14 and the hinge 11. During the extension and retraction process of the cylinder body 15, the damper body 12 is driven to rotate in a circle through the hinge 11 by the support columns 14, thereby achieving the purpose of controlling the opening and closing of the damper body 12.
[0021] Embodiment 2: A mine damper comprises a door frame 1, a fixed plate 2, a fixed block 16 and a connecting rope 26, hinges 11 are installed on the outer walls on both sides of the door frame 1, a damper body 12 is connected to the outer wall at one end of the hinge 11, an observation window 13 is embedded and installed inside the damper body 12, fixed plates 2 are installed on the outer walls on both sides of the damper body 12, a slide groove 21 is provided on the outer wall on one side of the fixed plate 2, a slider 22 is slidably installed inside the slide groove 21, a counterweight 23 is installed on the outer wall at one end of the slider 22, the counterweight 23 drives the lifting ring 25 to reset, a lifting ring 25 is installed on the outer wall at the upper end of the counterweight 23, and a fixed block 16 is installed on the outer wall on one side of the damper body 12.
[0022] The outer wall of the door frame 1 and the damper body 12 is installed with support columns 14, and the cylinder body 15 is rotatably installed between the support columns 14. As is well known to those skilled in the art, the damper body 12 device of the utility model also needs to provide the cylinder body 15 to make it work normally, and as is well known to those skilled in the art, the provision of the cylinder body 15 is commonplace, and it all belongs to conventional means or common knowledge, and will not be repeated here. Those skilled in the art can make any selection according to their needs or convenience.
