[0030] A degradable integrated lunch box, comprising

[0031] The box body 100 is in the shape of a hollow body with an open top wall. A mounting cavity 110 is formed in a concave shape around the upper edge of the box body 100. An adjusting frame 120 is provided in the inner cavity of the mounting cavity 110 for sliding and lifting;

[0032] Two vertical rotating rods 200 are rotatably provided on the bottom wall of the inner cavity of the installation cavity 110, and a screw rod 210 is provided on the top of each rotating rod 200. A screw hole 220 threadedly connected to the rod body of the screw rod 210 is opened at the bottom of the adjustment frame 120, and a worm gear 230 is provided on the rod body of the rotating rod 200. A driving rod 240 is rotatably provided through the side wall of the box body 100, and the rod body of the driving rod 240 is located in the inner cavity of the installation cavity 110 and is provided with a worm 250 that meshes with the worm gear 230.

[0033] Furthermore, the overall shape of the adjustment frame 120 is consistent with the shape of the inner cavity of the installation cavity 110, and the inner and outer side walls of the adjustment frame 120 are respectively fitted with the inner side walls of the installation cavity 110, and a sealing layer is provided on the fitted side walls. The sealing layer has a certain elasticity, which will not hinder the height adjustment of the adjustment frame 120, and can also make the outer side wall of the adjustment frame 120 fit more closely with the inner side wall of the installation cavity 110, thereby reducing the entry of water stains.

[0034] Furthermore, the top of the adjusting frame 120 protrudes from the upper edge of the box body 100, and a box cover 130 adapted to the adjusting frame 120 is movably installed, and a buckle ear 160 is rotatably provided on the outer wall of the box cover 130, and a convex edge 170 that is buckled with the buckle ear 160 is protruded from the top outer wall of the adjusting frame 120, which is a common structure for buckling the lunch box cover and the box body. The box cover 130 can also be hinged to one side of the upper edge of the adjusting frame 120, and the remaining side edges of the box cover 130 are buckled with the buckle ear 160 and the convex edge 170. In this way, the lunch box is integrated as a whole, and the loss of the box cover 130 after opening is avoided.

[0035] Furthermore, a partition 140 is provided inside the box body 100, and the rod body of the driving rod 240 rotates and penetrates the side wall of the partition 140. The partition 140 is used to separate dishes. When the amount of dishes is large, after adjusting the height of the adjustment frame 120, the lunch box can store a large amount of one dish separately.

[0036] Furthermore, a sealing ring 150 is protruding from the bottom of the box cover 130, and the outer wall of the sealing ring 150 is tightly attached to the inner wall of the adjustment frame 120. The sealing ring 150 has a certain elasticity. When the box cover 130 is closed, the outer wall of the sealing ring 150 is tightly attached to the inner wall of the adjustment frame 120, thereby properly sealing the adjustment frame 120.

[0037] Furthermore, a storage groove 180 is formed inwardly at the top of the box cover 130, and a handle 190 is symmetrically provided on the inner wall of the storage groove 180. The embedded handle 190 does not hinder the stacking of multiple box bodies 100, and can facilitate the user to hold the handle 190 and carry the device.

[0038] Furthermore, a knob 260 is provided at the front end of the driving rod 240, and guide rods 270 parallel to the screw 210 are provided around the bottom wall of the inner cavity of the installation cavity 110. A limiting block 280 is provided at the top of each guide rod 270, and limiting guide holes 290 are opened around the bottom of the adjustment frame 120. The inner diameter of the lowermost end of the limiting guide hole 290 is equal to the outer diameter of the guide rod 270 and is smaller than the outer diameter of the limiting block 280. The limiting block 280 is always located in the inner cavity of the limiting guide hole 290, thereby limiting the height of the adjustment frame 120 and preventing the adjustment frame 120 from separating from the installation cavity 110.

[0039] It should be noted that the entire device is made of degradable material.

[0040] During specific use, the user drives the driving rod 240 to rotate through the knob 260, and drives the two screws 210 to rotate simultaneously through the worm 250 and the worm wheel 230, so as to adjust the height of the adjustment frame 120 inside the installation cavity 110, so that the user can adjust the overall storage capacity of the lunch box according to the amount of food, which is convenient for use.

[0041] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
