[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Please refer to Figures 1-4, the present utility model provides a technical solution: a foam packing box, including a box body 1, an upper cover 101 is provided on the upper part of the box body 1, articles are placed inside the upper cover 101 and the box body 1 to protect the articles. An installation groove 102 is opened on the upper surface of the upper cover 101. The installation groove 102 is cylindrical as a whole. A rotating shaft 401 is rotatably connected to the middle of the installation groove 102. A guide plate 402 is fixedly connected to the outside of the rotating shaft 401. The guide plate 402 and the rotating shaft 401 are an integral body and rotate together. A guide groove 403 is opened on the surface of the guide plate 402. The guide groove 403 is arc-shaped as a whole. There are four guide grooves 403. When the guide plate 402 rotates, the guide groove 403 rotates accordingly. A chute is opened inside the upper cover 101. There are four chutes in total, one in each of the four directions. A first sliding bar 2 is slidably connected inside the horizontal chute. A first convex block 201 is fixedly connected to the top of the first sliding bar 2. The first sliding bar 2 and the first convex block 201 move together. The first convex block 201 contacts the guide groove 403. When the guide groove 403 rotates, the first convex block 201 can be made to move, and the first sliding bar 2 moves. The first sliding bar 2 is restricted by the horizontal chute and can only move along the direction of the horizontal chute. The moving directions of the two first sliding bars 2 are opposite. A second sliding bar 3 is slidably connected inside the vertical chute. A second convex block 301 is fixedly connected to the top of the second sliding bar 3. The second sliding bar 3 and the second convex block 301 move together. The second convex block 301 contacts the guide groove 403. When the guide groove 403 rotates, the second convex block 301 can be made to move, and the second sliding bar 3 moves. The second sliding bar 3 is restricted by the vertical chute and can only move along the direction of the vertical chute. The moving directions of the two second sliding bars 3 are opposite. When viewed from above, after the upper cover 101 is covered, when the guide plate 402 rotates clockwise, the first convex block 201 and the second convex block 301 move outwards, moving the first sliding bar 2 and the second sliding bar 3 outwards, and the upper cover 101 can be fixed. When the guide plate 402 rotates counterclockwise, the first convex block 201 and the second convex block 301 move inwards, moving the first sliding bar 2 and the second sliding bar 3 inwards, and the upper cover 101 can be removed. The guide plate 402 can only rotate 90 degrees each time. A first slot 202 is opened on the inner wall of the box body 1, and the first slot 202 is matched with the end of the first sliding bar 2. When the first sliding bar 2 moves outwards, it can be inserted into the first slot 202 to fix the upper cover 101. A second slot 302 is opened on the inner wall of the box body 1, and the second slot 302 is matched with the end of the second sliding bar 3. When the second sliding bar 3 moves outwards, it can be inserted into the second slot 302 to fix the upper cover 101. When in use, the first sliding bar 2 and the second sliding bar 3 move simultaneously.

[0021] Wherein, a rotating block 4 is fixedly connected to the top of the rotating shaft 401. By rotating the rotating block 4, the rotating shaft 401 can be rotated. There is a gap between the rotating block 4 and the installation groove 102, and a finger can reach in and rotate the rotating block 4.

[0022] Among them, a clamping strip 5 is slidably installed inside the upper cover 101. One side of the clamping strip 5 is fixedly connected to a spring 501, and the spring 501 is fixedly connected to the upper cover 101. A clamping hole is formed on the side surface of the rotating block 4, and the other side of the clamping strip 5 is matched with the clamping hole. There is only one clamping hole. When the first sliding strip 2 and the second sliding strip 3 are at the outermost side, the clamping hole is located at the corresponding position of the clamping strip 5. The clamping strip 5 can move left and right. The spring 501 moves the clamping strip 5 to the right, and the clamping strip 5 is inserted into the clamping hole, so that the rotating block 4 cannot rotate, the guiding plate 402 cannot rotate, and the first sliding strip 2 and the second sliding strip 3 cannot move. When the first sliding strip 2 and the second sliding strip 3 are not at the outermost side, the clamping strip 5 presses on the surface of the rotating block 4. Before use, the clamping strip 5 needs to be moved to the left to prevent the clamping strip 5 from affecting the rotation of the rotating block 4.

[0023] Among them, a mounting plate 404 is fixedly connected to the side wall of the mounting groove 102. The mounting plate 404 is rotatably connected to the rotating shaft 401. The mounting plate 404 plays a certain supporting role for the rotating shaft 401, making the structure of the rotating shaft 401 more stable.

[0024] Among them, the position of the horizontal sliding groove corresponds to that of the first slot 202, so that the first sliding strip 2 can smoothly slide into the first slot 202. The position of the vertical sliding groove corresponds to that of the second slot 302, so that the second sliding strip 3 can smoothly slide into the second slot 302.

[0025] Among them, the top of the rotating block 4 is flush with the top of the upper cover 101. When multiple boxes 1 are placed one above the other, the rotating block 4 will not affect the bottom of the upper box 1.

[0026] Working principle: When in use, after putting in the items, cover the upper cover 101, move the clamping strip 5 to the left, rotate the rotating block 4, the guiding plate 402 rotates, the guiding groove 403 rotates accordingly, the first convex block 201 and the second convex block 301 move outwards, move the first sliding strip 2 and the second sliding strip 3 outwards, the first sliding strip 2 is inserted into the first slot 202 internally, the second sliding strip 3 is inserted into the second slot 302 internally, fix the upper cover 101, release the clamping strip 5, the spring 501 moves the clamping strip 5 to the right, the clamping strip 5 is inserted into the clamping hole, and the rotating block 4 cannot rotate. When taking out the items, move the clamping strip 5 to the left and rotate the rotating block 4 in the reverse direction.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes and modifications can be made to these embodiments without departing from the principle of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
