The end of the movable rod 5 far away from the spring 4 is hemispherical, the movable rod 5 and the sleeve 3 form a relative sliding structure, the central axis of the rotating shaft 11 is parallel to the transverse central axis of the mounting plate 10, the rotating shaft 11 and the mounting plate 10 form a relative rotating structure, a gap is respectively reserved between the operating plate 12 and the upper cover 7 and the movable frame 8, and the operating board 12 is provided with 2 groups, the roller 17 is sleeved outside the mounting rod 16, and the roller 17 and the mounting rod 16 form a relative rotation structure, so that the operation panel 12 can be rotated, when the roller 17 onto which the operation panel 12 is rotated is brought into contact with the movable lever 5 and continues to apply pressure, the movable rod 5 can be made to slide into the interior of the sleeve 3, so that the roller 17 can pass over the movable rod 5, snap into the second groove 6, and the roller 17 can rotate at the outer side of the mounting rod 16 in the operation process, so that excessive friction is avoided;

the cross sectional shape of sealing member 9 is "mouth" font, and sealing member 9 constitutes relative sliding structure with upper cover 7, and sealing member 9 is the rubber material, the side sectional shape of briquetting 13 is the ellipse, and the relative operating panel 12's of briquetting 13 longitudinal central axis symmetric distribution, when making pivot 11 rotate, can make briquetting 13 rotate together, and make the longer internal diameter of briquetting 13 rotate to the direction of perpendicular to activity frame 8, make briquetting 13 constantly suppress activity frame 8 downstream, and then make sealing member 9 constantly slide down, until sealing member 9 is laminated with first recess 2's bottom completely, seal all around.

The working principle is as follows: when the airtight clamping structure for the household small square barrel is used, as shown in fig. 1 and 5, the sealing member 9 on the upper cover 7 is aligned with the first groove 2 on the square barrel main body 1 to be pressed and simultaneously rotate two sets of operation plates 12 downwards, the operation plates 12 can be manually rotated through the rotary connection between the rotating shaft 11 and the mounting plate 10 and the elasticity of the coil spring 14, so that the longer inner diameter of the pressing block 13 rotates towards the direction vertical to the movable frame 8, and the pressing block 13 continuously applies pressure to the movable frame 8 downwards, as shown in fig. 2 and 3, through the sliding connection between the sealing member 9 and the first groove 2, when the movable frame 8 is pressed downwards by the pressing block 13, the sealing member 9 can be continuously moved downwards, and along with the continuous rotation of the operation plate 12, the roller 17 on the operation plate 12 is contacted with the movable rod 5, and through the sliding connection between the movable rod 5 and the sleeve 3, the elasticity of the spring 4 and the contact surface of the movable rod 5 and the roller 17 are hemispherical, so that when the roller 17 continues to rotate along with the operating panel 12 to apply pressure to the movable rod 5, the movable rod 5 can slide into the sleeve 3, and further the roller 17 can cross the movable rod 5 and move to the other side of the movable rod 5, and meanwhile, through the rotating connection between the roller 17 and the mounting rod 16, the roller 17 can move through rotation in the process of contacting with the movable rod 5, thereby avoiding easy damage to the device itself, at this time, the movable rod 5 loses the pressure of the roller 17, under the elastic action of the spring 4, the movable rod 5 slides out of the sleeve 3 again, the operating panel 12 is released, under the elastic action of the coil spring 14, the roller 17 rotates in the opposite direction until the roller 17 is clamped into the second groove 6, and as compared with the coil spring 14, the spring 4 is not easy to deform, at the moment, under the condition of no human action, the roller 17 cannot enable the movable rod 5 to slide into the sleeve 3, so that the position of the roller 17 is fixed, the position of the operation plate 12 is fixed, clamping is completed, and in the whole operation process, the friction force between the devices is small, so that the devices cannot be used continuously due to the fact that the devices are not damaged easily when the devices are used for a long time;

as shown in fig. 3 and 4, after the square barrel body 1 and the upper cover 7 are fastened, the operation plate 12 drives the pressing block 13 to have a longer inner diameter perpendicular to the movable frame 8, so that the pressing effect of the pressing block 13 on the movable frame 8 is maximized, and the sealing element 9 is tightly attached to the bottom of the first groove 2, thereby ensuring the air tightness in the square barrel body 1, avoiding the circulation of air between the inside and the outside, ensuring the storage tightness of the objects in the square barrel body 1, and when the square barrel body needs to be opened, the two sets of operation plates 12 are rotated upwards at the same time, under the enough pressure of manual operation, the roller 17 presses the movable rod 5 again to enter the sleeve 3, so that the roller 17 can cross the movable rod 5, thereby limiting the operation plates 12 is released, and further fixing between the square barrel body 1 and the upper cover 7 is released, and the upper cover 7 is taken down from the square barrel body 1.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
