The packaging box in the prior art is usually a general paper box and cannot effectively protect articles in the transportation process, so that the articles can be prevented from being worn and damaged by impact caused by bumping due to objective external reasons in the transportation process, the transported articles can not be kept in a horizontal state all the time when special articles are transported, and the problems that the articles in the box are inconvenient to take out and cannot be reused are solved.

When in use: firstly, the box cover 1 is opened, because the box cover 1 is rotatably connected to the box body 2 through the first rotating shaft 4, when the box cover 1 is opened, the box cover 1 drives the first rotating shaft 4 to rotate to draw a second traction rope 27 (as shown in fig. 10 and fig. 11) wound on the first rotating shaft 4, the second traction rope draws a pull plate 21 which is slidably connected to the synchronizing plate 11 through a fifth spring 23 downwards, and therefore the synchronizing plate 11 drives a limiting column 19 fixedly connected with the synchronizing plate to be disengaged from an inner gear ring 20 fixedly connected below a gear 25; because the gear 25 is rotationally connected to the carrying plate 5 and is connected with the sliding block 7-1 which is slidably connected in the carrying plate 5 through the rack 22, when the limiting column 19 is separated from the inner gear ring 20 which is fixedly connected below the gear 25, the limitation on the rotational freedom degree of the gear 25 is lost, and the fixed claw 7 which is fixedly connected to the sliding block 7-1 can slide in the limiting groove 5-1 together with the sliding block 7-1;

since the first rotating shaft 4 is further connected with a second rotating shaft 30 (as shown in fig. 13) through a second belt 28, a second transmission cylinder 29 rotationally connected with the case body 2 is arranged on the outer ring of the second rotating shaft 30, since the outer side of the second rotating shaft 30 and the inner side of the second transmission cylinder 29 are both provided with a stop 31, and the difference between the two stop 31 is 90 degrees, the second rotating shaft 30 can drive the second transmission cylinder 29 to rotate after rotating 90 degrees, so that the second transmission cylinder 29 can wind up the first traction rope 6, and the fixed claws 7 can be pulled apart (as shown in fig. 12, 13 and 14 combined with fig. 2), since the four fixed claw 7 cylinders are jointly engaged with the gear 25 through the rack 22 fixedly connected with the fixed claw 7 cylinders, when one fixed claw 7 is pulled apart, the other three fixed claws can synchronously move under the drive of the gear 25, so that the four fixed claws 7 can be completely opened after the case cover 1 is completely opened;

meanwhile, the first rotating shaft 4 is also connected with a first transmission cylinder 26 through a first belt 9, the first transmission cylinder 26 is rotatably connected in the box body 2, the inner side of the first transmission cylinder 26 is provided with a limiting block 10, the limiting block 10 is rotatably connected in the box body 2, and a part of the limiting block 10, which is positioned in the first transmission cylinder 26, is fixedly connected with a stop block 31 matched with the stop block 31 arranged in the first transmission cylinder 26, and in addition, the difference between the two stop blocks 31 is 90 degrees; therefore, the limiting block 10 can rotate synchronously with the first rotating shaft 4 after the box cover 1 is opened for a certain angle, the carrying plate 5 is jacked up under the driving of the box cover 1, and the carrying plate 5 is fixed by matching with the fixing groove 5-2 arranged below the carrying plate 5;

then, an article to be placed is placed in the center of the object carrying plate 5, the box cover 1 is closed, in the process of closing the box cover 1, the limiting block 10 can reset under the action of the torsion spring, and then the limiting block 10 is separated from the fixing groove 5-2 of the object carrying plate 5, meanwhile, the second transmission cylinder 29 can reset under the action of the torsion spring and the first spring 8 fixedly connected to the sliding block 7-1, so that the first traction rope 6 wound on the first transmission cylinder 26 resets, and at the moment, the fixing claw 7 can fix the article under the action of the first spring 8;

subsequently, the second pulling rope 27 is completely reset, the pulling plate 21 pushes the limiting column 19 into the inner gear ring 20 again under the action of the fifth spring 23, and the gear 25 is fixed under the action of the limiting column 19 because the pulling plate 21 is in sliding connection with the sleeve 14 arranged in the box through the pillar 24 and the spring, so that the fixing claw 7 meshed with the pulling plate through the rack 22 cannot move, and the object placed in the box cannot be separated from the fixing claw 7 under the action of external force;

in the process of transporting the article, because two pairs of balance frames 12 which are connected with the article carrying plate 5 and the synchronous plate 11 in a sliding way are arranged between the article carrying plate 5 and the synchronous plate 11, the article carrying plate 5 and the box body 2 are connected in a sliding way through a synchronous rod 16; so that the horizontal state can be maintained in the case 2 even if the articles are not uniformly put in; because the third spring 17 is arranged between the carrying plate 5 and the synchronous plate 11, the carrying plate 5 can absorb shock through the third spring 17 when the box body 2 jolts up and down, and because the carrying plate 5 is connected with the synchronous plate 11 in a vertical sliding manner through the balance frame 12, the carrying plate 5 can keep horizontal and vertical synchronous motion with the synchronous plate 11, and because the cross sleeve 13 is fixedly connected below the synchronous plate 11, the cross sleeve 13 is sleeved with the two connecting rods which are connected to the inner wall of the box body 2 in a sliding manner, and the second spring 15 is arranged between the cross sleeve 13 and the connecting rods, the horizontal and vertical shock absorption can be carried out through the second spring 15 when the carrying plate 5 and the synchronous plate 11 move synchronously;

that is to say, carry thing board 5 and can keep away from with box body 2 under the effect of second spring 15 and third spring 17, carry the shock attenuation, through with article with carry thing board 5 fixed connection, make article and carry thing board 5 synchronous motion to avoid producing relative motion and then avoid friction and striking to reach the effect of avoiding article to be worn and torn.

In the practical use process of the invention, the object can be effectively fixed on the object carrying plate 5 by the fixing claws 7 arranged on the object carrying plate 5, the limitation of the object by the fixing claws 7 is controlled by opening and closing the box cover 1 through the matching of the pull plate 21 connected with the first traction rope 6 and the second traction rope 27 and the fixing claws 7, the object carrying plate 5 is lifted and the object carrying plate 5 is limited at the initial position through the driving of the first rotating shaft 4 by the limiting block 5-1, so as to ensure that the object can be easily taken out when the box is opened, the object can still be ensured to be in the horizontal state when the object is uniformly placed by the balance frame 12 connected between the object carrying plate 5 and the synchronous plate 11, the object carrying plate 5 and the box body 2 keep a distance under the action of the second spring 15 and the third spring 17 for shock absorption, the object and the object carrying plate 5 are fixedly connected, so that the object and the object carrying plate 5 synchronously move to avoid the generation of relative movement and further avoid friction and collision, thereby achieving the effect of avoiding the articles from being worn.

As a further scheme of the invention: the fixing claws 7 are detachable fixing claws 7, so that the fixing claws can be conveniently matched with articles of different shapes.

As a further scheme of the invention: the fillet has been seted up to 1 right angle department of lid, can reduce the deformation that produces because of the collision when packing carton is collided.
