A person skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0019] Example 1: A packaging structure for firecrackers, such as Figure 1-Figure 4 As shown, it includes a packaging box 1, which is open, and a plurality of fixing plates 2 are fixed to the bottom of the inner wall of the packaging box 1. The plurality of fixing plates 2 are evenly spaced, and the top of each fixing plate 2 is glued with two holders 3 by glue. The two holders 3 are symmetrically arranged, and a firecracker 31 is placed between the two holders 3 on the same fixing plate 2. A cover plate 32 is slidably connected to the upper part of the packaging box 1, and the cover plate 32 is used to increase the airtightness of the packaging box 1. A locking mechanism is provided on the packaging box 1, and a clamping mechanism is provided on the packaging box 1. The locking mechanism is used to lock the cover plate 32, reduce the moisture rate of the firecracker 31, and improve the sealing of the packaging box 1. The clamping mechanism is used to clamp the firecracker 31 to improve the stability of the firecracker 31 during transportation.

[0020] The holder 3 is made of rubber material and is used to limit the firecracker 31 .

[0021] The locking mechanism includes a sliding column 4, and two sliding columns 4 are slidably connected to the upper part of the packaging box 1. The two sliding columns 4 are symmetrically arranged. A horizontal spring 5 is provided between the sliding column 4 and the packaging box 1. The horizontal spring 5 is used to drive the sliding column 4 to reset. One end of the sliding column 4 is fixedly connected to a limiting frame 6, and the limiting frame 6 is provided with an inclined surface. The cover plate 32 will contact the inclined surface on the limiting frame 6, and the cover plate 32 is used to drive the limiting frame 6 to move.

[0022] The clamping mechanism includes an inclined block 7, and the bottom of the cover plate 32 is fixedly connected to the inclined block 7. The cover plate 32 is used to drive the inclined block 7 to move. The inclined block 7 is provided with an inclined surface. A lower pressure plate 8 is slidably connected to the inner wall of the packaging box 1. The top of the lower pressure plate 8 will contact the inclined surface of the inclined block 7, and the bottom of the lower pressure plate 8 will contact the firecracker 31.

Two vertical springs 9 are provided between the lower pressure plate 8 and the packaging box 1. The two vertical springs 9 are symmetrically arranged. The vertical springs 9 are used to drive the lower pressure plate 8 to reset.

[0023] Initially, the staff will place the firecrackers 31 one by one into the card seat 3, and the card seat 3 will limit the firecrackers 31 by the elasticity of the rubber. After the firecrackers 31 are placed, the staff will push the cover 32 to cover the open part of the packaging box 1. The cover 32 moves to contact the inclined surface on the limit frame 6 and pushes the two limit frames 6 in the direction away from each other. The two limit frames 6 move in the direction away from each other, driving the two sliding columns 4 to move in the direction away from each other. The horizontal spring 5 is compressed, and the cover 32 continues to move and separates from the limit frame 6. When the cam 32 is in the closed position, the two limit frames 6 move in a direction away from each other, and the two limit frames 6 move in a direction away from each other, and the two limit frames 6 will limit the cover plate 32. Through the above operation, the cover plate 32 can be conveniently locked, thereby reducing the moisture absorption rate of the firecracker 31 and improving the sealing of the packaging box 1. The movement of the cover plate 32 drives the inclined block 7 to move. The inclined surface of the inclined block 7 contacts the lower pressure plate 8 and squeezes the lower pressure plate 8 downward. The vertical spring 9 is compressed, and the lower pressure plate 8 moves downward and contacts the firecracker 31. Through the above operation, it is convenient to clamp the firecracker 31 and improve the stability of the firecracker 31 during transportation. When the firecracker 31 is needed to be used, the staff will move the two limit frames 6 in the direction away from each other, and the two limit frames 6 move in the direction away from each other, driving the two sliding columns 4 to move in the direction away from each other. The horizontal spring 5 is compressed, and the limit frame 6 no longer limits the cover plate 32. Then the staff pushes the cover plate 32 in the opposite direction, and the cover plate 32 no longer The opening of the packaging box 1 is covered to facilitate the removal of the firecrackers 31. After the cover plate 32 is opened, the staff releases the limit frame 6, the horizontal spring 5 will rebound and drive the two sliding columns 4 to move in the direction of approaching each other, and the two sliding columns 4 move in the direction of approaching each other, driving the two limit frames 6 to move in the direction of approaching each other. The cover plate 32 moves in the opposite direction, driving the inclined block 7 to move in the opposite direction. The inclined surface on the inclined block 7 no longer squeezes the lower pressure plate 8, and the vertical spring 9 will rebound and drive the lower pressure plate 8 to move upward, and the lower pressure plate 8 no longer clamps the firecrackers 31.

One side of the protective cover 10 is in contact with the cover plate 32. The cover plate 32 is used to drive the protective cover 10 to move. A reset spring 11 is provided between the protective cover 10 and the packaging box 1. The reset spring 11 is used to drive the protective cover 10 to reset.

[0025] Sandpaper 12 is also included. Two pieces of sandpaper 12 are fixed to the outer wall of the packaging box 1. The sandpaper 12 is used to facilitate the firing of the firecracker 31.

[0026] When the cover 32 is closed, the cover 32 moves to contact one side of the protective cover 10 and drives the protective cover 10 to move toward the direction close to the firecracker 31. The return spring 11 is stretched, and the protective cover 10 moves toward the direction close to the firecracker 31 to cover the gunpowder end of the firecracker 31, thereby improving the safety of the firecracker 31 during transportation. When the cover 32 is closed, the cover 32 moves in the opposite direction and disengages from the protective cover 10.
