[0027] In one embodiment of the utility model, a snap box 21 is fixedly installed on the outside of the foam box 1, a long spring telescopic rod 22 is fixedly installed on the inside of the snap box 21, a long column 23 is fixedly installed on the inside of the long spring telescopic rod 22, a long wheel 24 is rotatably installed on the outside of the long column 23, a short spring telescopic rod 25 is fixedly installed on the end of the inner side of the snap box 21 away from the long spring telescopic rod 22, a short column 26 is fixedly installed on the inside of the short spring telescopic rod 25, a short wheel 27 is rotatably installed on the outside of the short column 26, a rotating shaft 28 is fixedly installed on the inside of the snap box 21, and a rotating shaft 28 is fixedly installed on the inside of the snap box 21. A Z-shaped block 29 is rotatably mounted on the outer side of the shaft 28, a short groove 210 is provided inside the buckle box 21, an L-shaped block 211 is slidably mounted inside the short groove 210, and a concave buckle 212 is fixedly mounted on the outer side of the foam box 1. When the foam plastic packaging boxes need to be stacked, the buckle box 21 is aligned with the concave buckle 212, and the L-shaped block 211 is manually pressed to slide up and down in the short groove 210. The long spring telescopic rod 22 and the short spring telescopic rod 25 are equidistantly arranged at the left and right ends of the buckle box 21 with the vertical center line of the buckle box 21 in the left and right directions as the central axis. A Z-shaped block 29 is slidably mounted on the outer side of the long wheel 24 and the short wheel 27, so that the Z-shaped block 29 rotates under the fixation of the rotating shaft 28, so that one side of the Z-shaped block 29 presses the short wheel 27, increasing the friction of the pressing, so that the Z-shaped block 29 is pressed more steadily, and the circular cross-sections of the long wheel 24 and the short wheel 27 are in the same horizontal plane. The rotating shaft 28 is coaxial with the center of the circular cross section of the Z-shaped block 29, and the buckle box 21, the long spring telescopic rod 22, the long column 23, the long wheel 24, the short spring telescopic rod 25, the short column 26, the short wheel 27, the rotating shaft 28, the Z-shaped block 29, the short groove 210, the L-shaped block 211 and the concave buckle 212 are provided in multiple groups, and the multiple groups of the buckle box 21, the long spring telescopic rod 22, the long column 23, the long wheel 24, the short spring telescopic rod 25, the short column 26, the short wheel 27, the rotating shaft 28, the Z-shaped block 29, the short groove 210, the L-shaped block 211 and the concave buckle 212 are mirrored with the vertical center line of the left and right directions of the foam box 1 The axis is mirror-set on the left and right sides of the foam box 1, so that the short column 26 prompts the short spring telescopic rod 25 to move downward, and further the other side of the Z-shaped block 29 is tilted upward, so that the concave buckle 212 presses the long wheel 24 and the long column 23, so that the long spring telescopic rod 22 falls to a suitable position, and then the L-shaped block 211 is released and pressed, so that the other side of the Z-shaped block 29 stops tilting and fits with the concave buckle 212, so that the foam plastic packaging boxes are aligned and fastened when stacked, and then it is not easy to shift when carrying the foam plastic packaging boxes. Conversely, when the foam plastic packaging boxes need to be unloaded, the L-shaped block 211 is pressed and moved again.
[0028] In one embodiment of the utility model, a fixing mechanism 3 is provided on the foam box 1, and a long groove 31 is provided on the foam box 1. A ball spring 32 is fixedly installed inside the long groove 31, and a ball column 33 is fixedly installed outside the ball spring 32. A support column 34 is fixedly installed outside the foam box 1. In order to make the foam plastic packaging box more stable, after the foam plastic packaging boxes are stacked, the support column 34 drops into the long groove 31, so that the support column 34 pushes the ball column 33 to move, and a circular hole 35 is provided on the support column 34. The ball column 33 is coaxial with the center of the circular cross section of the circular hole 35. The long groove 31, the ball spring 32, the ball column 33, the support column 34 and the circular hole 35 are provided in four groups, so that the ball column 33 squeezes the ball spring 32. When the circular hole 35 drops and aligns with the ball column 33, the ball spring 32 reversely squeezes the ball column 33, so that the ball column 33 is stuck into the circular hole 35, and then the foam plastic packaging boxes are more stable when they are stacked.
[0029] Working principle: when the foam plastic packaging boxes need to be stacked, the buckle box 21 is aligned with the concave buckle 212, and the L-shaped block 211 is manually pressed to slide up and down in the short groove 210, so that the Z-shaped block 29 rotates under the fixation of the rotating shaft 28, so that one side of the Z-shaped block 29 presses the short wheel 27, increasing the pressing friction, making the Z-shaped block 29 press more smoothly, so that the short column 26 prompts the short spring telescopic rod 25 to move downward, and further the other side of the Z-shaped block 29 is tilted upward, so that the concave buckle 212 presses the long wheel 24 and the long column 23, so that the long spring telescopic rod 22 falls to a suitable position, and then the L-shaped block 211 is released and pressed, so that the other side of the Z-shaped block 29 stops tilting and fits and snaps with the concave buckle 212, so that the foam plastic packaging boxes are aligned and fastened when stacked, and then it is not easy to shift when carrying the foam plastic packaging boxes. Conversely, when the foam plastic packaging boxes need to be unloaded, the L-shaped block 211 is pressed and moved again. In order to make the foam plastic packaging boxes more stable, after the foam plastic packaging boxes are stacked, the support column 34 drops into the long groove 31, so that the support column 34 pushes the spherical column 33 to move, so that the spherical column 33 squeezes the ball spring 32, and when the round hole 35 drops to align with the spherical column 33, the ball spring 32 squeezes the spherical column 33 in the opposite direction, so that the spherical column 33 is stuck into the round hole 35, thereby making the foam plastic packaging boxes more stable when stacked.
[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
