Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides a double safety lock plastic safety box through improvement. The technical solution of the present utility model is as follows:

[0024] As Figures 1-3 shown, a double safety lock plastic safety box includes a box body 1, a cover plate 2 is hinged on the box body 1, and further includes;

[0025] Card slots 13, two card slots 13 are opened in the box body 1. The cross-section of the card slot 13 is in an "L" shape. The card slots 13 are located on the left and right sides of the box body 1. Two connection slots 14 are opened in the cover plate 2. Two worm gears 15 and two worm wheels 17 are respectively rotatably connected in the two connection slots 14. The worm gear 15 meshes with the worm wheel 17. Two connection shafts 18 are respectively fixedly connected to the two worm wheels 17. Two clamping rods 19 are respectively fixedly connected to the two connection shafts 18. The cross-section of the clamping rod 19 is in an "L" shape. By inserting the clamping rod 19 into the card slot 13, the left and right sides of the cover plate 2 are fixed to the box body 1, making the connection between the cover plate 2 and the box body 1 more firm and improving the practicability of the device.

[0026] Furthermore, as Figure 1 shown, a groove 4 is opened on the cover plate 2. A handle 5 is rotatably connected in the groove 4. The cross-section of the handle 5 is in a "return" shape. When storing, the handle 5 is inserted into the groove 4, reducing the occupied area of the handle 5 and making the device convenient for storage.

[0027] Furthermore, as Figure 1 and Figure 3 shown, four bases 3 are fixedly connected to the box body 1. The bases 3 are located at the bottom of the box body 1, preventing the box body 1 from directly contacting the ground and playing a certain moisture-proof effect. Two knobs 16 are respectively fixedly connected to the two worm gears 15.

[0028] Furthermore, as Figures 1-3 shown, two fixing seats 6 are fixedly connected to the box body 1. The top of the fixing seat 6 is flush with the top of the box body 1. Two clamping seats 7 are fixedly connected to the cover plate 2. The bottom of the clamping seat 7 is flush with the bottom of the cover plate 2. The cross-section of the clamping seat 7 is in an "L" shape.

[0029] Furthermore, as Figure 2As shown, four sliding grooves 8 are respectively provided on the two fixed seats 6. The two adjacent sliding grooves 8 are symmetrical about the snap-fit ​​seat 7. Four sliders 9 are slidably connected in the four sliding grooves 8 respectively.

[0030] Furthermore, such as Figure 1 and Figure 3 As shown, four springs 10 are fixedly connected to the four sliders 9 respectively, and the four springs 10 are fixedly connected to the four slide grooves 8 respectively. Four connecting plates 11 are rotatably connected to the four sliders 9 respectively, and two clamping plates 12 are fixedly connected to the four connecting plates 11 respectively. By inserting the clamping plates 12 into the clamping seats 7, one side of the cover plate 2 is fixed to the box body 1, while the other two sides of the cover plate 2 are fixed by the clamping rods 19. The last side of the cover plate 2 is hinged to the box body 1, so that the cover plate 2 is fixed to the box body 1 on all four sides, thereby ensuring that the device is more stable and firm when moving.

[0031] The specific working method is as follows: Rotate the cover plate 2 so that the bottom of the cover plate 2 fits against the top of the box 1. Then rotate the connecting plate 11, causing the locking plate 12 to rotate. While rotating the connecting plate 11, push the slider 9 upward, causing the connecting plate 11 to move. When the connecting plate 11 rotates 180 degrees, the locking plate 12 is located above the locking seat 7. Then release the connecting plate 11. Under the action of the spring 10, the slider 9 moves downward, causing the connecting plate 11 and the locking plate 12 to move downward, embedding the locking plate 12 into the locking seat 7. Inside the receiving seat 7, the fixing seat 6 and the locking seat 7 are fixed, thus completing the fixation of one side of the cover plate 2. Then, the knob 16 is turned to drive the worm gear 15 to rotate. Since the worm gear 15 meshes with the worm wheel 17, the worm wheel 17 starts to rotate, driving the connecting shaft 18 and the locking rod 19 to rotate, so that the locking rod 19 is embedded in the locking groove 13. The other two sides of the cover plate 2 are fixed by the locking rod 19, thus completing the locking of the cover plate 2, so that the cover plate 2 is firmly attached to the box 1, improving the practicality of the device.
