[0028] like Figures 1 to 6As shown, the specific embodiment of the utility model provides a recyclable turnover box with locking protection, including a box body 1 and a box cover 2 arranged on the box body 1, a connecting plate 3 is fixedly connected to the box body 1, and a protrusion 4 is fixedly connected to the box cover 2; a locking component for connecting the box cover 2 and the box body 1 is provided between the connecting plate 3 and the protrusion 4, and the box cover 2 can be locked on the box body 1 by setting the locking component, so that the turnover box can achieve locking protection, the locking component includes a clamping block 5 fixedly connected to the protrusion 4, and the clamping block 5 is provided with a notch, a stopper 6 is provided in the connecting plate 3, and a connecting rod 7 is fixedly connected to the stopper 6; it also includes an unlocking component arranged in the connecting plate 3 for opening the box cover 2, by setting the unlocking component, the box cover 2 locked at the top of the box body 1 can be opened, thereby unlocking the turnover box with locked protection, which is convenient for use, and the unlocking component includes a threaded rod 8 arranged in the connecting plate 3, a push plate 9 is threadedly connected to the threaded rod 8, and a baffle 10 is fixedly connected to the end of the connecting rod 7.

[0029] like Figure 2 , Figure 5 and Figure 6 As shown, specifically, a plurality of hinge blocks 11 are fixedly installed on the box body 1, and the plurality of hinge blocks 11 are rotatably connected to the box cover 2. A rotating shaft 12 is rotatably connected between the hinge blocks 11 and the box cover 2. When the box cover 2 is buckled on the top of the box body 1 for locking, the box cover 2 is rotated so that the box cover 2 rotates with the rotating shaft 12 as the axis and under the cooperation of the hinge blocks 11, so that the protrusion 4 on the box cover 2 gradually approaches the connecting plate 3, and then the box cover 2 is gradually buckled on the top of the box body 1. The rotating shaft 12 is provided There is a torsion spring 13, and the elastic shafts at both ends of the torsion spring 13 are tightly attached to the box cover 2 and the box body 1 respectively. A limiting ring 14 is fixedly installed in the box body 1, and the elastic shaft at one end of the torsion spring 13 passes through the limiting ring 14. In the process that the box cover 2 is gradually buckled on the top of the box body 1, the elastic shafts at both ends of the torsion spring 13 are acted upon by force under the rotation of the box cover 2, thereby generating a reaction force. The setting of the limiting ring 14 limits the elastic shaft of the torsion spring 13, thereby maintaining the stability of the torsion spring 13.

[0030] like Figures 2 to 6As shown, specifically, a groove 15 is provided in the connecting plate 3, and the stopper 6 is slidably connected to both sides of the groove 15, one end of the block 5 and both sides of the block 6 are inclined at the same angle, and in the process of the box cover 2 being buckled onto the top of the box body 1, the block 5 on the protrusion 4 gradually enters the groove 15 and contacts the block 6, and the block 5 applies pressure to the block 6.

When the stop block 6 is disengaged from the groove 15, the stop block 6 pushes the connecting rod 7 to move, and the connecting rod 7 drives the limit plate 16 to move, so that the moving limit plate 16 applies pressure to the spring 17 to cause it to contract and generate a reaction force, until the inclined surfaces of the block 5 at both ends gradually disengage from the inclined surfaces on the stop block 6, and the stop block 6 is engaged into the notch on the block 5 under the reaction force of the spring 17, so that the stop block 6 completes the engagement and limiting of the block 5, that is, the box cover 2 is locked in the box body 1.

[0031] like Figures 2 to 6 As shown, specifically, the push plate 9 is slidably connected in the connecting plate 3, and the push plate 9 is tightly attached to the baffle 10, the threaded rod 8 is rotatably connected to the connecting plate 3, and one end of the threaded rod 8 is fixedly connected to a connecting block 18, and the connecting block 18 is provided with a hexagonal rotating groove, one side of the connecting block 18 is provided with a rotating block 19 adapted to the hexagonal rotating groove, and the rotating block 19 is fixedly connected with a rotating handle 20. When it is necessary to open the box cover 2 buckled on the box body 1, the staff takes out the carried rotating block 19 and inserts it into the hexagonal rotating groove in the connecting block 18, and then rotates the rotating handle 20 to drive the threaded rod 8 to rotate, so that the push plate 9 on the threaded rod 8 moves in the connecting plate 2, and the moving push plate 9 pushes the baffle 10 to move, so that the baffle 10 drives the connecting rod 7 The box cover 2 is then opened and the box body 1 is unlocked, and the connecting rod 7 drives the stopper 6 to move and disengage from the notch on the card block 5, until the stopper 6 is completely disengaged from the card block 5, and the card limit on the card block 5 is cancelled, that is, the box cover 2 is no longer locked in the box body 1. At this time, the box cover 2 is rotated and opened with the rotating shaft 12 as the axis under the reaction force of the torsion spring 13, so that the turnover box can be used after the box cover 2 is opened. A lifting handle 21 is provided on the box body 1. The setting of the lifting handle 21 is convenient for lifting the turnover box. After the box cover 2 automatically pops open, the rotating block 19 is rotated in the reverse direction to rotate the threaded rod 8, so that the push plate 9 moves in the reverse direction to reset, and the reaction force generated by the spring 17 will also push the limit plate 16 to move and reset, that is, push the connecting rod 7 and the stopper 6 to move and reset, and then the rotating block 19 can be taken out and collected.
