DETAILED DESCRIPTION

[0021] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0022] like Figure 1-5 As shown, the utility model is a lunch box with an adjustable internal space, comprising a box body 1 and a frame body 2, wherein an insert ring 11 is fixedly installed on the inner wall of the box body 1, a retractable plate 23 is slidably connected inside the frame body 2, a first insert block 21 is fixedly installed on one side of the frame body 2, a first insert rod 22 is provided below the first insert block 21, a second insert block 24 is fixedly installed on one side of the retractable plate 23, a second insert rod 25 is provided below the second insert block 24, a plurality of insert rings 11 are fixedly installed around the inside of the box body 1, the first insert block 21 and the second insert block 22 are ... the inner wall of the box body 1, and the first insert block 21 and the second insert block 22 are fixedly installed on the inner wall of the box body 1. The insert ring 11 is slidably connected, and the first inserting block 21 and the second inserting block 24 drive the first inserting rod 22 and the second inserting rod 25 at the bottom thereof to be inserted into the inserting ring 11. Through the frame 2 and the shrinking plate 23, a partition can be formed inside the box body 1. At the same time, the shrinking plate 23 is slidably connected to the frame 2, and the width of the shrinking frame 2 and the shrinking plate 23 can be freely adjusted. The frame 2 and the shrinking plate 23 can be inserted into the inserting ring 11 horizontally or vertically, which can facilitate the adjustment of the internal space of the box body 1 more conveniently, and is suitable for placing different foods in the lunch box.

[0023] A limiting plate 3 is fixedly provided on one side of the outer side of the box body 1, a limiting groove 31 is provided on the limiting plate 3, a limiting block 32 is provided inside the limiting groove 31, a shifting block 33 is provided at the outer end of the limiting block 32, and a first spring 34 is provided at the bottom of the limiting block 32. When the box body needs to be closed, the upper part of the box body 1 is connected to the cover plate 12 by hinge rotation. By rotating the upper cover plate, a clamping plate 14 is fixedly installed on the side of the cover plate 12, and a clamping block 15 is symmetrically provided at the bottom of the clamping plate 14. The clamping block 15 matches the limiting block 32, and the clamping plate 14 on the cover plate 12 drives the clamping block 15 to move to the limiting groove 31, and the clamping block 15 can When the block 15 slides in the limit groove 31 and slides downward, the limit block 32 can be squeezed. A slide groove 35 is provided inside the limit plate 3, and the slide groove 35 is slidably connected to the limit block 32. One end of the spring 34 is fixedly connected to the inner wall of the slide groove 35, and the other end is fixedly connected to the bottom of the limit block 32. The limit block 32 can slide inside the slide groove 35. When the limit block 32 is squeezed, the first spring 34 can be squeezed. When the block 15 moves to the bottom, the limit block 32 can lock it to prevent the cover 12 from opening due to collision during the transportation of the lunch box, thereby causing the meal inside to fall.

[0024] In the above solution, a handle 13 is fixedly provided above the cover plate 12 to facilitate the transportation of the box body 1.

[0025] In the above scheme, a second spring 36 is provided at the bottom of the limit groove 31, and a push block 37 is provided on the top of the second spring 36. When the cover needs to be opened, by pulling the outer push block of the limit plate 3, the push block can squeeze the first spring 34, drive the limit block 32 to move inward, and release the restriction on the card block 15. At the same time, in the process of locking the card block 15, the second spring 36 at the bottom can be squeezed. When the card block 15 is released from the restriction, the second spring 36 returns to its original state and can push the push block 37 at the top. The push block 37 can push the card block 15 outward, which is convenient for releasing the restriction between the card plate 14 and the limit plate 3 and opening the box body 1.

[0026] Working principle:

[0027] This kind of lunch box has an adjustable internal space. During operation, the box body 1 is divided according to the required food. The box body 1 can be divided horizontally or vertically by inserting the first plug block 21 and the second plug block 24 into the plug ring 11, so as to maximize the space utilization of the box body 1. After the food is placed, the box body 1 is closed by closing the cover 12. The block 14 at the bottom of the cover 12 can be embedded in the limiting groove 31. The limiting block 3 completes the locking effect of the cover 12, so as to prevent the cover 12 from falling off and the food from spilling to the outside of the box body 1 when the box body 1 encounters a collision, thereby preventing the waste of resources.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
