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.

[0019] Please see Figure 1-4 This utility model provides a technical solution for a circuit board production storage box:

[0020] according to Figure 1-4 As shown, it includes a U-shaped lower box 1 and a U-shaped upper box 2. The U-shaped upper box 2 is slidably connected to both sides of the U-shaped lower box 1. A lower fixing plate 4 is fixedly provided at the bottom of the U-shaped lower box 1, and an upper fixing plate 5 is fixedly provided at the top of the U-shaped upper box 2. Multiple positioning grooves are equidistantly provided on the surfaces of the lower fixing plate 4 and the upper fixing plate 5. Two slots 16 are provided on both sides of the U-shaped lower box 1, and a U-shaped side plate 6 is inserted between the two slots 16 on the same side.

[0021] Specifically, the storage box consists of a U-shaped lower box 1 and a U-shaped upper box 2 that are slidably connected. The internal space can be adjusted according to the size of the circuit board, making it suitable for storing circuit boards of different sizes. At the same time, U-shaped side plates 6 are provided on both sides of the U-shaped lower box 1 for protection, effectively limiting and fixing the stored circuit boards and improving the stability of the circuit board placement.

[0022] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, T-shaped grooves 7 are provided on both sides of the U-shaped lower box 1, and T-shaped sliders 9 are slidably connected inside the two T-shaped grooves 7. The T-shaped sliders 9 are fixedly connected to the inner walls of the U-shaped upper box 2.

[0023] A trapezoidal lead screw 8 is rotatably connected between the top and bottom of the two T-shaped slides 7. The trapezoidal lead screw 8 is threadedly connected to the middle of the T-shaped slider 9. A transmission mechanism is provided between the two trapezoidal lead screws 8.

[0024] The transmission mechanism includes a transmission shaft 11, a first bevel gear 12, and a second bevel gear 13. A cavity 10 is provided at the bottom of the U-shaped lower housing 1. The transmission shaft 11 is rotatably connected to both sides of the inner wall of the cavity 10. The first bevel gear 12 is fixedly installed at both ends of the transmission shaft 11. The bottom ends of the two trapezoidal lead screws 8 extend into the cavity 10 and are fixedly installed with the second bevel gear 13. The second bevel gear 13 meshes with the corresponding first bevel gear 12. A circular rotating block 14 is fixedly installed at one end of the transmission shaft 11 through the cavity 10.

[0025] Specifically, the transmission mechanism drives two trapezoidal lead screws 8 to rotate synchronously. The rotation of the trapezoidal lead screws 8 drives the T-shaped slider 9 to rise and fall inside the T-shaped slide groove 7. The movement of the T-shaped slider 9 drives the movement of the U-shaped upper box 2, which facilitates the adjustment of the height of the circuit board between the U-shaped lower box 1 and the U-shaped upper box 2.

[0026] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, each of the four slots 16 has a through groove 18 at its top, and each of the two U-shaped side plates 6 has a threaded hole 15 on both sides of its top.

[0027] Specifically, the U-shaped side plate 6 is easily fixed in the set position of the slot 16 by the cooperation of the gasket 19 and the locking bolt 17.

[0028] Both sides of the U-shaped upper box 2 are provided with lifting slots 3.

[0029] Specifically, the opening of the lifting slot 3 facilitates the handling of the storage box.

[0030] Working principle: This utility model discloses a circuit board production storage box. When using this storage box to store circuit boards, firstly, the distance between the U-shaped lower box 1 and the U-shaped upper box 2 is adjusted according to the size of the circuit board. Then, the circular rotating block 14 is manually rotated, which drives the transmission shaft 11 to rotate. The rotation of the transmission shaft 11 drives the first bevel gear 12 to rotate. The first bevel gear 12 meshes with the second bevel gear 13, thereby driving the trapezoidal screw 8 to rotate. The rotation of the trapezoidal screw 8 drives the T-shaped slider 9 to rise and fall. The rise and fall of the T-shaped slider 9 drives the rise and fall of the U-shaped upper box 2, so that the distance between the U-shaped lower box 1 and the U-shaped upper box 2 is adapted to the height of the circuit board. Next, the circuit board is placed in the positioning groove between the lower fixing plate 4 and the upper fixing plate 5 for fixation. Then, the U-shaped side plate 6 is manually pushed so that the inner wall of the U-shaped side plate 6 contacts the side of the circuit board. Finally, the locking bolt 17 is threadedly connected to the threaded hole 15 to ensure the stability of the placed circuit board.
