[0020] 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.

[0021] Please see Figures 1-5 As shown, a packaging wooden box with a replaceable bottom plate includes a bottom plate 1 and a side plate 2 disposed above the bottom plate 1. The side plate 2 has a first cavity 11 inside and two second cavities 13 communicating with the first cavity 11 inside. A control mechanism is disposed inside the first cavity 11. Two grooves 12 are disposed on the lower end face of the side plate 2. The inner walls of the two grooves 12 are respectively provided with mounting grooves 14 communicating with the two second cavities 13. A locking mechanism is disposed between the second cavities 13 and the mounting grooves 14.

[0022] refer to Figure 4 and Figure 5 As shown, the control mechanism includes a gear 25 rotatably connected inside the first cavity 11. The first cavity 11 is provided with two racks 16 that mesh with the gear 25. The front and rear end faces of the two racks 16 are fixedly connected with slide bars 17. The front and rear inner walls of the first cavity 11 are provided with slide grooves 15 that match the slide bars 17. The outer wall of the side plate 2 is rotatably connected with a knob 24 that is fixedly connected to the gear 25.

[0023] It should be noted that by rotating the knob 24, the knob 24 drives the gear 25 to rotate. The gear 25 meshes with the rack 16, thereby driving the two racks 16 to move relative to or in opposite directions. The racks 16 drive the slide bar 17 to move inside the slide groove 15, making the movement of the rack 16 more stable.

[0024] refer to Figure 4 and Figure 5As shown, the second cavity 13 is slidably connected to a connecting rod 18 that is fixedly connected to a rack 16. The placement groove 14 is slidably connected to a locking plate 19 that is fixedly connected to the other end of the connecting rod 18. The inner wall of the first cavity 11 is provided with a slot 21. The slot 21 is slidably connected to a slide rod 22 that is fixedly connected to the connecting rod 18. The outer wall of the slide rod 22 is provided with a spring 23 located between the connecting rod 18 and the first cavity 11. The upper end face of the bottom plate 1 is fixedly connected with a plurality of buckles 8 corresponding to the groove 12. The top of the inner wall of the buckle 8 abuts against the locking plate 19. The inner wall of the groove 12 away from the placement groove 14 is provided with a slot 20 that matches the locking plate 19.

[0025] It should be noted that: when the side plate 2 is placed on the upper surface of the bottom plate 1, the buckle 8 enters the interior of the groove 12. The connecting rod 18 is pressed by the spring 23, causing the connecting rod 18 to move inside the second cavity 13, thereby driving the clamping plate 19 to move inside the placement groove 14, so that the clamping plate 19 enters the groove 12. One end of the clamping plate 19 passes through the buckle 8 and enters the clamping groove 20, which facilitates the fixing of the buckle 8, and thus facilitates the fixing of the bottom plate 1 and the side plate 2. The connecting rod 18 drives the sliding rod 22 to slide inside the slot 21, making the movement of the connecting rod 18 more stable, while preventing the spring 23 from deviating.

[0026] refer to Figure 2 and Figure 3 As shown, there are four side panels 2. One end of the side panel 2 is fixedly connected to a T-shaped strip 9. The inner wall of the side panel 2 is provided with a T-shaped groove 10 that matches the T-shaped strip 9. The upper end face of the rear side panel 2 is movably connected to a cover plate 3 via a hinge 7. The front end face of the cover plate 3 is fixedly connected to an L-shaped plate 5. The front end face of the front side panel 2 is fixedly connected to a fixing plate 4. The outer walls of the fixing plate 4 and the L-shaped plate 5 are both provided with lock holes 6.

[0027] It should be noted that: by inserting adjacent T-shaped strips 9 into the interior of T-shaped grooves 10, the adjacent side plates 2 are more secure and easy to disassemble and assemble. The cover plate 3 is movably connected above the side plate 2 by hinges 7, making it easy to flip the cover plate 3. The lock holes 6 of the fixing plate 4 and the L-shaped plate 5 are aligned to make it easy to fix the cover plate 3.

[0028] Working principle: Adjacent T-shaped strips 9 are inserted into the T-shaped groove 10, connecting adjacent side plates 2. Rotating knob 24 clockwise causes gear 25 to rotate clockwise. Gear 25 meshes with rack 16, causing the two racks 16 to move relative to each other, which in turn causes connecting rod 18 and locking plate 19 to move relative to each other, allowing locking plate 19 to fully enter the mounting groove 14. Simultaneously, spring 23 is compressed. Then, side plates 2 are placed on the upper surface of bottom plate 1, allowing buckle 8 to enter the groove 12. Loosen the knob 24, and the spring 23 will press the connecting rod 18, causing the connecting rod 18 to move inside the second cavity 13. This will move the locking plate 19 into the groove 12, and at the same time, reset the knob 24 and the rack 16. The locking plate 19 passes through one end, through the buckle 8, and into the slot 20, which facilitates the fixing of the buckle 8. This, in turn, facilitates the fixing of the bottom plate 1 and the side plate 2. When disassembling, simply turn the knob 24 clockwise again to disengage the locking plate 19 from the buckle 8, and the bottom plate 1 can be disassembled, making the operation more convenient.
