[0023] Reference Figure 1 , Figure 2 and Figure 4The utility model provides an embodiment: an iron-plastic packaging box that is easy to open, including a packaging box body 1, a top cover plate 3 is rotatably connected to the top of the packaging box body 1, and the rear end of the top cover plate 3 is connected to the upper side of the rear end of the packaging box body 1 through a plurality of tension springs 8. The inner sides of the packaging box body 1 are rotatably connected with a placing plate frame 2, and the inner sides of the packaging box body 1 are provided with limited sliding grooves 12, and the inner sides of the limited sliding grooves 12 are slidably connected with a traction slider 10, and the inner side of the traction slider 10 is fixedly connected with a lifting rod 9, and both sides of the traction slider 10 are equipped with a Unicom exhibition The opening component, the upper front end of the packaging box body 1 is fixedly connected with a connecting box body 5, and a quick opening component is installed inside the connecting box body 5. The connecting expansion component includes a fixing seat 14 located on both sides of the traction slider 10, and the inside of the fixing seat 14 is rotatably connected with a linkage push rod 13, and the outer sides of the linkage push rod 13 are respectively rotatably connected to the inner side of the placement plate frame 2, and the inner upper sides of the limiting sliding groove 12 are fixedly connected with magnetic blocks 15. The upper and lower sides of the traction slider 10 are provided with adsorption grooves 11, and the outer sides of the magnetic blocks 15 are respectively magnetically attracted to the inside of the adsorption grooves 11;

[0024] The lifting rod 9 is pulled upward to make the traction slider 10 slide inside the limiting sliding groove 12. As the traction slider 10 moves upward, the inner side of the linkage push rod 13 is lifted upward by the fixing seat 14, so that the angle between the linkage push rod 13 and the inner side of the placement plate frame 2 changes, so that the placement plate frames 2 on both sides slide outward at the same time, so that the placement plate frames 2 are unfolded, and the upper adsorption groove 11 contacts the outer side of the upper magnetic block 15, so as to stabilize, put the harder objects into the interior of the packaging box body 1, and the softer objects into the interior of the placement plate frame 2, and place them separately, press the lifting rod 9 downward, and pull the placement plate frame 2 back into the interior of the packaging box body 1 through the linkage push rod 13, and the lower adsorption groove 11 contacts the lower magnetic block 15, so as to stabilize, and place the hard objects and the soft objects separately, thereby improving the utilization effect of the internal space of the packaging box and the protection of the soft objects.

[0025] Reference Figure 2 , Figure 3 and Figure 5 The quick opening assembly includes a push rod 4 located on both sides of the connecting box body 5, the inner sides of the push rod 4 are fixedly connected to the limited position fixing block 17, the inner sides of the limited position fixing block 17 are connected through the extrusion spring 16, the front end of the top cover plate 3 is fixedly connected to the front side fixing block 6, the bottom end of the front side fixing block 6 is fixedly connected to the limited position fixing frame 18, the outer lower sides of the limited position fixing block 17 are respectively correspondingly slidably connected to the inner sides of the connecting box body 5, and the protrusions of the limited position fixing block 17 are engaged with the notches of the limited position fixing frame 18;

[0026] When the top cover 3 is opened, the pushing rods 4 on both sides are pressed inwardly at the same time. As the pushing rods 4 are pushed, the limiting fixing blocks 17 are moved inwardly at the same time, so that the notch of the limiting fixing frame 18 is disengaged from the snap-in of the limiting fixing block 17, and the tension spring 8 generates a pulling force outward on the top cover 3, thereby separating the limiting fixing frame 18 from the interior of the connecting box body 5, opening and flipping the top cover 3, closing the top cover 3, and inserting the limiting fixing frame 18 into the interior of the connecting box body 5. The bottom inclined surface of the limiting fixing frame 18 contacts the inclined surface of the limiting fixing block 17, and the limiting fixing block 17 is squeezed inwardly at the same time. When the snap-in of the limiting fixing block 17 contacts the notch of the limiting fixing frame 18, the extrusion spring 16 generates a thrust on the limiting fixing block 17, thereby fixing it in the interior of the limiting fixing frame 18, completing the fixation, making the opening and closing of the packaging box more convenient, and improving the efficiency of opening and closing the packaging box.

[0027] Reference Figure 1 , a screen printing plate 7 is fixedly connected to the middle of the top of the top cover plate 3;

[0028] When the box body needs to be printed and marked, the mark is printed on the surface of the screen printing plate 7, thereby preventing the box body from being damaged due to printing.

[0029] Working principle: When opening the top cover 3, the push rods 4 on both sides are pressed inward at the same time, and the limit fixing block 17 is moved inward at the same time as the push rods 4 are pushed, so that the notch of the limit fixing frame 18 is separated from the snap-in of the limit fixing block 17, and the tension spring 8 generates an outward pulling force on the top cover 3, so that the limit fixing frame 18 is separated from the inside of the connecting box body 5, and the top cover 3 is opened and turned over, and it is pulled upward by the lifting rod 9, so that the traction slider 10 is in the limit sliding groove As the traction slider 10 moves upward, the inner side of the linkage push rod 13 is lifted upward through the fixed seat 14, so that the angle between the linkage push rod 13 and the inner side of the placement plate frame 2 changes, so that the placement plate frames 2 on both sides slide outward at the same time, so that the placement plate frames 2 are unfolded, and the upper adsorption groove 11 contacts the outer side of the upper magnetic block 15, so as to stabilize, put harder objects into the packaging box body 1, and put softer objects into the placement plate frame 2, and place them separately.
