[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] This embodiment provides an internally adjustable enclosure box, such as... Figures 1-5 As shown, the enclosure box includes a placement shell 1, a shock-absorbing structure 2 installed at the bottom of the inner cavity of the placement shell 1, an enclosure box body 3 installed on the shock-absorbing structure 2, and an adjustment structure 4 installed on the enclosure box body 3.

[0024] The shock-absorbing structure 2 includes two sets of fixed plates 21 symmetrically installed at the bottom of the inner cavity of the housing 1. Crossbars 22 are symmetrically installed on the corresponding side walls of the two sets of fixed plates 21. A first spring 23 is installed on the fixed plate 21 and outside the crossbar 22. A first sliding sleeve 24 connected to the first spring 23 is slidably installed on the outer wall of the crossbar 22. A movable rod 26 is rotatably installed on the first sliding sleeve 24. The other ends of the four sets of movable rods 26 are rotatably installed with a mounting bracket 27. The shock-absorbing structure 2 also includes fixed cylinders 28 installed at the four corners of the bottom of the inner cavity of the housing 1 and a second spring 210 sleeved on the outside of the fixed cylinders 28. An inner rod 29 connected to the bottom of the enclosure box body 3 is slidably installed on the inner wall of the fixed cylinders 28.

[0025] When in use, the precision instrument is placed in the fence box body 3, and the fence box body 3 is sealed by the box cover. When the fence box body 3 is transported, the fence box body 3 is provided on the four groups of inner rods 29 and the mounting frame 27, so that the shock absorption function of the fence box body 3 is realized. When the placing shell 1 is shaken and vibrated, the fence box body 3 is driven to move up and down on the mounting frame 27 and the inner rod 29 under the shaking condition. The inner rod 29 slides up and down on the inner wall of the fixed cylinder 28. The mounting frame 27 drives the movable rod 26 to move. The movable rod 26 is driven by the connecting frame 25, and then the first sliding sleeve 24 slides on the cross rod 22. The first sliding sleeve 24 extrudes the first spring 23. At the same time, the fence box body 3 compresses the second spring 210. Therefore, the first spring 23 and the second spring 210 buffer and absorb the vibration force of the fence box body 3. The problem that the precision instrument in the fence box is damaged due to the vibration of the fence box under the shaking condition when the precision instrument is packaged and transported by the existing fence box is avoided. Therefore, the shock absorption protection effect of the precision instrument in the fence box body 3 is realized, and unnecessary loss is reduced.

[0026] In the embodiment, the connecting frame 25 is installed on the first sliding sleeve 24. The end of the movable rod 26 away from the mounting frame 27 is rotationally connected with the connecting frame 25 through a through hole. The front and rear sides of the mounting frame 27 are connected with the bottom of the fence box body 3. The inner cavity of the placing shell 1 is slidingly connected with the outside of the fence box body 3. The outer wall of the cross rod 22 and located at the center is provided with a support sleeve 211 connected with the bottom of the inner cavity of the placing shell 1.

[0027] The support sleeve 211 is provided. When the cross rod 22 is bent due to the heavy weight of the fence box body 3, the support sleeve 211 can provide support for the center of the cross rod 22, so that the bending of the cross rod 22 due to the weight is avoided.

[0028] In the embodiment, the lower end of the second spring 210 is connected with the bottom of the inner cavity of the placing shell 1. The upper end of the second spring 210 is connected with the bottom of the fence box body 3. The lower end of the inner rod 29 is provided with a limiting piece 291.

[0029] The limiting piece 291 is provided. When the inner rod 29 slides up and down in the fixed cylinder 28, the limiting piece 291 can avoid the inner rod 29 from being separated from the fixed cylinder 28, so that the stable operation of the fixed cylinder 28 is ensured.
