[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example: Figure 1-4 As shown, the utility model provides a drop-proof packaging carton, including a box frame 1, the top and bottom ends of the box frame 1 are provided with box plates 2, the inner sides of the box plates 2 are provided with sealing grooves 10, the top of the box frame 1 is movably inserted into the sealing groove 10, the inside of the box plate 2 is provided with a mounting groove 3, the inside of the mounting groove 3 is rotatably connected with a rotating rod 4, the outer side of the rotating rod 4 is fixedly connected with a rotating plate 5, both ends of the rotating plate 5 are rotatably connected with connecting rods 6, the inner walls of the mounting grooves 3 are slidably clamped with movable plates 7, the ends of the connecting rods 6 away from each other are rotatably connected to the corresponding movable plates 7, the side of the movable plate 7 away from the connecting rod 6 is fixedly connected with a clamping block 8, both sides of the box frame 1 are clamped with clamping grooves 9, and the clamping blocks 8 are movably inserted in the clamping grooves 9.

[0019] One end of the rotating rod 4 away from the box frame 1 extends to the outside of the box frame 1 and is fixedly connected with a knob 12 .

[0020] By adopting the above technical solution and providing the knob 12 , it is convenient to better rotate and adjust the rotating rod 4 , thereby facilitating the removal of the box plate 2 from the outer side of the box frame 1 .

[0021] A torsion spring 11 is arranged between the side of the knob 12 close to the box frame 1 and the box frame 1. The torsion spring 11 is movably sleeved on the outside of the A Zi rotating rod 4. One end of the torsion spring 11 is fixedly connected to the rotating rod 4, and the other end of the torsion spring 11 is fixedly connected to the box frame 1.

[0022] By adopting the above technical solution and setting the torsion spring 11, when the rotating rod 4 is no longer subjected to the rotational force, the rotating rod 4 can be reset. At the same time, the elastic force of the torsion spring 11 can be used to make the clamping block 8 more secure when inserted into the inside of the clamping slot 9.

[0023] Handle grooves 13 are provided on both sides of the box frame 1 .

[0024] By adopting the above technical solution and providing the handle groove 13, fingers can be inserted into the handle groove 13 to facilitate better picking up and placing of the carton.

[0025] The outer sides of the box plates 2 are all fixedly connected with buffer pads 14 .

[0026] By adopting the above technical solution and providing the buffer pad 14, when the top surface or the ground of the carton hits the ground during the falling process, the impact force generated can be buffered, thereby preventing the goods from being damaged when falling.

[0027] The side of the buffer pad 14 away from the box plate 2 is fixedly connected with an anti-skid pad 15 .

[0028] By adopting the above technical solution and providing the anti-skid pad 15, the anti-skid property and stability of the box can be improved.

[0029] One side of the clamping block 8 is provided with an inclined surface.

[0030] By adopting the above technical solution, by providing a slope on one side of the clamping block 8, when the clamping block 8 contacts the box frame 1, it is easier to push the clamping block 8 to move inward, thereby making it more convenient to install the box plate 2 on the box frame 1.

[0031] Working principle: When assembling the carton, after gluing the four faces of the box frame 1, the box plate 2 is placed over the opening of the box frame 1, and the two sides of the box frame 1 are inserted into the corresponding sealing grooves 10, and the box plate 2 is used to reinforce the faces of the box frame 1. When installing the box plate 2, when the clamping block 8 is connected to the box frame 1, the clamping blocks 8 on both sides are pushed inward at the same time, and one end of the connecting rod 6 is pushed to move synchronously, and the other end of the connecting rod 6 is limited by the rotating plate 5, and at the same time, the connecting rod 6 is pushed. The rotating rod 4 and the rotating plate 5 rotate, and the torsion spring 11 generates a torsion force. When the clamping block 8 moves to the position corresponding to the clamping block 8 and the clamping slot 9, the elastic force of the torsion spring 11 is used to push the rotating plate 5 to rotate in the opposite direction, so that the clamping block 8 is inserted into the inside of the clamping slot 9, thereby fixing the relative position of the box frame 1 and the box plate 2, and completing the sealing of the box frame 1. Similarly, by rotating the knob 12, the clamping block 8 is pulled out from the inside of the clamping slot 9, and the restriction on the vertical movement of the box plate 2 is released, so that the box frame 1 is opened conveniently;

[0032] When the top surface or the ground of the carton hits the ground during the falling process, the impact force generated can be buffered by the buffer pad 14, thereby preventing the goods from being damaged when falling.

[0033] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
