DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] like Figures 1 to 9 As shown, the present invention provides an airtight fresh-keeping box with a convenient lid opening, comprising a box body 1 and a box cover 2, wherein a mounting seat 3 extends downward from the bottom edge of the box cover 2, a mounting groove 4 is provided on the outer side of the mounting seat 3, a sealing member is arranged in the mounting groove 4, and when the box cover 2 is buckled on the box body 1, the sealing member is squeezed on the inner wall of the box body 1 to achieve sealing between the two, a hinged portion 5 is provided on one side of the box body 1, a flip cover 6 is hinged on the hinged portion 5, a top block 61 extends inwardly from the middle of the bottom of the flip cover 6, a vertical channel 51 is provided in the middle area of ​​the hinged portion 5, a lifting block 7 is installed in the vertical channel 51, the box cover 2 is located below the flip cover 6 and above the lifting block 7; when the flip cover 6 is flipped upward, the top block 61 rotates to contact the bottom surface of the lifting block 7 and pushes the lifting block 7 to rise, and finally the box cover 2 is lifted upward by the top surface of the lifting block 7 to separate the box cover 2 from the box body 1.

[0023] On the basis of the above scheme, the area below the flip cover 6 on the box cover 2 is provided with a vent hole 21, and the bottom surface of the flip cover 6 is correspondingly provided with a sealing rod 62. When the flip cover 6 is closed, the sealing rod 62 is inserted into the vent hole 21 to achieve sealing.

[0024] In addition, a concave operating groove 22 is provided on the top surface of the box cover 2, and the front end of the flip cover 6 is located in the operating groove 22. A space for inserting fingers is reserved between the bottom surface of the flip cover 6 and the top surface of the operating groove 22.

[0025] In addition, the hinged parts 5 on both sides of the vertical channel 51 are vertically provided with sliding grooves 52, and the bottom of the lifting block 7 is upwardly opened with two left and right deformation grooves 71, and the two sides of the bottom surface of the lifting block 7 protrude outward to form limit blocks 72. After the bottom of the lifting block 7 is pressed inwardly and deformed, it is inserted into the vertical channel 51 from top to bottom and is inserted into the sliding groove 52 through the limit blocks 72 on both sides to guide the lifting.

[0026] Furthermore, hinge columns 53 extend outwardly from the left and right sides of the hinge portion 5 , and hinge plates 63 extend correspondingly from the two sides of the flip cover 6 . The hinge plates 63 are provided with hinge holes 631 for the hinge columns 53 to be inserted into.

[0027] like Figures 4 to 6 As shown, when it is necessary to open, a finger is inserted into the space between the bottom surface of the flip cover 6 and the top surface of the operating slot 22, and the flip cover 6 is pulled up. The top block 61 at the bottom of the flip cover 6 rotates synchronously, and the top block 61 contacts the bottom surface of the lifting block 7 and pushes the lifting block 7 to rise. The top surface of the lifting block 7 contacts the bottom surface of the box cover 2, and the box cover 2 is pushed up by the top block 61. The lifting force is greater than the friction force of the seal pressing on the inner wall of the box body 1, thereby achieving smooth separation of the box cover 2 and the box body 1.

[0028] Similarly, when food needs to be put in and the cover needs to be closed, it is only necessary to put the cover 2 on the top surface of the box body 1, the bottom surface of the cover 2 contacts the lifting block 7, press the cover 2 down, the cover 2 pushes the lifting block 7 to slide downward, the bottom of the lifting block 7 drives the top block 61 to rotate, and the flip cover 6 flips down synchronously, finally realizing that the cover 2 is closed on the box body 1 and the flip cover 6 flips and closes in place.
