[0024] The following will combine the accompanying drawings of the specification to give a detailed explanation and description of the protective packaging box provided by the present utility model.

[0025] This embodiment specifically discloses a protective packaging box, as Figure 1 and 2 shown, which includes a box body 1, a circumferential fixing mechanism 2, and an axial fixing mechanism 3. The box body 1 includes a base 11 and a box cover 12. The box cover 12 covers the base 11 and is hermetically connected to the base 11. The base 11 is used to support the circumferential fixing mechanism 2, the axial fixing mechanism 3, and the packaged object. Both the base 11 and the box cover 12 are in the shape of a cuboid. A sealing groove 111 is circumferentially formed on the edge of the base 11, and a sealing strip is provided in the sealing groove 111. The box cover 12 is snapped into the sealing groove 111 and pressed on the sealing strip. The box cover 12 and the base 11 are locked by a lock 14, so that the lower edge of the box cover 12 is pressed tightly on the sealing strip, enabling the entire protective packaging box to be waterproof and dustproof, and preventing water and dust from entering the interior of the box body 1 and affecting the packaged object. Preferably, the lock 14 is a stainless steel spring lock. A plurality of locks 14 can be evenly arranged circumferentially on the box body 1. In this embodiment, the number of locks 14 is 12. Five locks 14 are arranged on each of the left and right sides of the box body 1, and the locks 14 on both sides are symmetrically arranged. One lock 14 is arranged at each of the front and rear ends of the box body 1, and the two locks 14 at the front and rear ends are in corresponding positions.

[0026] As Figure 2 shown, the circumferential fixing mechanism 2 is arranged inside the box body 1. The circumferential fixing mechanism 2 includes one or more hoop clamps 21 arranged along the length direction of the box body 1. The packaged object is placed inside the box body 1 along the length direction of the box body 1, and the length direction of the box body 1 is parallel to the axial direction of the packaged object. The number of hoop clamps 21 can be set according to the length of the packaged object. Usually, the number of hoop clamps 21 is set to be multiple, and multiple hoop clamps 21 are arranged along the axial direction of the packaged object and surround the packaged object, with good fixing effect. As Figure 2 and 3 shown, the hoop clamp 21 includes an upper half hoop clamp 211 and a lower half hoop clamp 212. The lower half hoop clamp 212 is fixed on the base 11. The lower half hoop clamp 212 is fixedly connected to the base 11 through a bracket. The bracket is arranged below the lower half hoop clamp 212 to support the lower half hoop clamp 212. The bottom of the bracket is fixedly connected to the base 11 by bolts or welded to the base 11. The upper half hoop clamp 211 is detachably connected to the lower half hoop clamp 212. The inner surfaces of both the upper half hoop clamp 211 and the lower half hoop clamp 212 are arc-shaped. The inner surfaces of the upper half hoop clamp 211 and the lower half hoop clamp 212 refer to the surfaces in contact with the packaged object.

[0027] Optionally, as Figure 3As shown in the figure, the upper half hoop 211 and the lower half hoop 212 are detachably connected by a bolt and nut assembly. Both ends of the lower half hoop 212 are provided with first connection ears 213, and both ends of the upper half hoop 211 are provided with second connection ears 214. A bolt 4 is rotatably or fixedly connected to the first connection ear 213. The bolt 4 can be fixedly connected to the first connection ear 213. At this time, the first connection ear 213 and the second connection ear 214 are horizontally arranged, and the bolt 4 is fixedly mounted on the first connection ear 213 perpendicular to the first connection ear 213. The bolt 4 can also be rotatably connected to the first connection ear 213. As Figure 3 shown in the figure, a fixed seat 6 is provided on the upper surface of the first connection ear 213. A rotating shaft 61 is fixed inside the fixed seat 6. The rotating shaft 61 is arranged along the length direction of the box body 1. The bottom end of the bolt 4 is sleeved on the rotating shaft 61 and rotates around the rotating shaft 61. A through hole for the bolt 4 to pass through is formed on the first connection ear 213. A nut 5 is threadedly connected to the bolt 4 and is located above the second connection ear 214. The upper half hoop 211 is placed downward from above the lower half hoop 212. If the bolt 4 is rotatably connected to the first connection ear 213, the angle of the bolt 4 is adjusted by rotating the bolt 4 around the rotating shaft 61 so that the through hole on the second connection ear 214 is sleeved on the bolt 4. Connecting the nut 5 from the top of the bolt 4 can realize the connection between the upper half hoop 211 and the lower half hoop 212, and then hold the packaged object tightly. The connection form in which the bolt 4 is rotatably connected to the first connection ear 213 can be applied to more sizes and specifications of packaged objects, such as irregular cylindrical packaged objects, which can be slightly adjusted according to the shape of the product, and the fixation is more firm, reducing the shock during the transportation of the packaged object.

[0028] As Figure 3 shown in the figure, a handle is provided at the vertex of the outer surface of the upper half hoop 211, which is convenient for the staff to hold and lift the upper half hoop 211 and place it above the lower half hoop 212.

[0029] Optionally, shock pads are provided on the inner surfaces of both the upper half hoop 211 and the lower half hoop 212. Preferably, the shock pads are made of felt. The shock pads reduce the shock impact on the packaged object during transportation. At the same time, the frictional force formed by the shock pads after the upper half hoop 211 and the lower half hoop 212 press the packaged object also helps with the axial fixation of the packaged object.

[0030] As Figure 2 shown in the figure, the axial fixing mechanism 3 is fixed on the base 11. The axial fixing mechanism 3 includes a front blocking mechanism 31 and a rear blocking mechanism 32 arranged along the length direction of the box body 1. The front blocking mechanism 31 is fixed in front of the circumferential fixing mechanism 2, and the rear blocking mechanism 32 is fixed behind the circumferential fixing mechanism 2. The packaged object is clamped from the front and back to prevent the packaged object from sliding back and forth. The circumferential fixing mechanism 2 and the axial fixing mechanism 3 fix the packaged object in all directions, preventing the packaged object from moving relative to the box body 1 during transportation and generating shock.

[0031] Optionally, as Figure 2 shown, one of the front blocking mechanism 31 and the rear blocking mechanism 32 is a blocking plate fixed perpendicular to the base 11. The blocking plate can be fixed to the base 11 through a horizontal connecting plate. The connecting plate is fixedly connected to the base 11 by bolts and nuts. Preferably, a reinforcing rib is provided between the blocking plate and the connecting plate to enhance the blocking and supporting effect of the blocking plate. The other of the front blocking mechanism 31 and the rear blocking mechanism 32 includes a fixed base 321 and a blocking rod 322. The fixed base 321 is fixed on the base 11. A threaded hole is provided on the fixed base 321, and the axial direction of the threaded hole is along the length direction of the box body 1. The blocking rod 322 is threadedly connected to the fixed base 321, that is, the blocking rod 322 is provided with an external thread and is a lead screw structure. The distance between the blocking rod 322 and the blocking plate can be adjusted by rotating the blocking rod 322, thereby adjusting the clamping degree of the packaged object.

[0032] Optionally, a hand wheel 323 is fixed to the end of the blocking rod 322 far from the circumferential fixing mechanism 2, which is convenient for rotating the blocking rod 322. The end of the blocking rod 322 close to the circumferential fixing mechanism 2 can be set to have a larger end face area to increase the contact area with the packaged object.

[0033] In this embodiment, the front blocking mechanism 31 is a blocking plate, and the rear blocking mechanism 32 includes a fixed base 321 and a blocking rod 322. The number of the front blocking mechanism 31 is one, and the number of the rear blocking mechanism 32 is two. The two rear blocking mechanisms 32 are arranged at intervals along the width direction of the box body 1.

[0034] Optionally, lifting rings 15 are symmetrically provided on both sides of the base 11 and the box cover 12, which can realize the lifting of the box body 1 and the packaged object inside. Preferably, the number of the lifting rings 15 on the box cover 12 is 4, with two on each side; the number of the lifting rings 15 on the base 11 is 6, which are symmetrically distributed on both sides of the base 11, with three on each side. The distances between the lifting rings among the three lifting rings on the same side can be the same or different, and the 6 lifting rings 15 are used simultaneously. The lifting rings 15 on the box cover 12 are used for the separate lifting of the box cover 12. The 6 lifting rings 15 on the base 11 are used for the lifting of the base when it is empty and the overall lifting of the protective packaging box after placing the packaged object.

[0035] Optionally, as Figure 2 shown, vertical guide rods 13 are provided at the four corners of the base 11, which play a guiding role when the box cover 12 is lowered and installed on the base 11 by hoisting, facilitating the alignment of the lower edge of the box cover 12 with the sealing groove 111 and reducing the alignment difficulty.

[0036] Optionally, an anti-static paint layer is provided on the outer surfaces of the box cover 12 and the base 11 to achieve the anti-corrosion and anti-rust functions of the box body 1 itself.

[0037] Optionally, a grounding post is provided on the box body 1. The grounding post can be arranged on the base 11 for grounding to protect the protective packaging box and the packaged item inside.

[0038] The usage method of the protective packaging box of this application is as follows:

[0039] Lift the base 11 to the designated platform, then place the packaged item on the lower half hoop 212 and make the front end face of the packaged item contact the front blocking mechanism 31. Place the upper half hoop 211 on the upper half hoop 211 and the packaged item. The through hole on the second connecting ear 214 is sleeved on the bolt 4. Connect the nut 5 to the bolt 4 but do not tighten it. Rotate the blocking rod 322 so that its front end abuts against the rear end face of the packaged item. The blocking plate and the blocking rod 322 clamp the packaged item. At this time, tighten the nut 5. The upper half hoop 211 and the lower half hoop 212 tightly hold the packaged item circumferentially, and the packaged item is firmly fixed in the box body 1. Lift and install the box cover 12 so that the lower edge of the box cover 12 is clamped into the sealing groove 111 of the base 11. Lock all the latches 14, and the lower edge of the box cover 12 presses the sealing strip. Then, lift the protective packaging box and the packaged item inside to another designated position.
