[0005] The purpose of this utility model is achieved through the following technical solution: a metal packaging box with a shock-absorbing buffer layer, including a lid and a box body, both of which are made of aluminum alloy. The lid is rotatably mounted on the box body, and the lid and the box body are closed by a lock. The closed lid and the box body form a receiving cavity. Buffer pads are fixed on the inner walls of the receiving cavity, and a buffer block is also included. The buffer block is used to separate the receiving cavity. Positioning holes are provided on the buffer pads located at the bottom of the box body. There are several positioning holes arranged in a matrix. The bottom of the buffer block is provided with an installation hole, and a positioning pin is inserted into the installation hole. The buffer block is fixed to the corresponding buffer pad by inserting the positioning pin into the positioning hole.

[0006] Preferably, the buffer pad has the same structure as the buffer block. The buffer pad is one of pearl cotton, EVA foam, or silicone. The buffer pad is covered with cotton cloth, and the cotton cloth on the buffer pad is fixed to the inner wall of the receiving cavity with glue.

[0007] Preferably, a vent hole is provided at the center of the box cover. The vent hole is a countersunk through hole with its larger end away from the receiving cavity. A waterproof and breathable membrane is installed inside the vent hole.

[0008] Preferably, it also includes a dust cover, on the inner arc surface of which a plastic tube is fixed. The plastic tube consists of two sections with different outer diameters. The smaller diameter plastic tube is away from the dust cover and can be detachably installed at the larger end of the vent hole. The larger diameter plastic tube has an air exchange hole.

[0009] Preferably, the small-diameter plastic tube has a shrinkage slit, and the shrinkage slit is a plurality of such slits evenly distributed along the axis of the plastic tube. The shrinkage slit is narrowed by inserting the small-diameter plastic tube into the vent hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: By fixing the buffer block to different positions on the bottom buffer pad with positioning pins, the receiving cavity is divided into chambers of different sizes for placing parts of different specifications. The structure is simple and the size of the chambers can be easily changed. Moreover, the structure is stable after the buffer block is fixed and is not easy to move. This avoids the parts being moved due to the increase in the size of the chamber, which could cause collisions. It is suitable for transporting parts of multiple specifications at the same time.

[0018] like Figure 1-3As shown, a metal packaging box with a shock-absorbing buffer layer includes a lid 1 and a body 2. Both the lid 1 and the body 2 are made of aluminum alloy. The lid 1 is rotatably mounted on the body 2. The lid 1 and the body 2 are closed by a latch 3, forming a receiving cavity. Buffer pads 4 are fixed on the inner walls of the receiving cavity, and buffer blocks 5 are also included. The buffer blocks 5 are used to divide the receiving cavity. Positioning holes 6 are provided on the buffer pads 4 at the bottom of the body 2. There are several positioning holes 6 arranged in a matrix. The bottom of the buffer blocks 5 is provided with mounting holes, and positioning pins 7 are inserted into the mounting holes. The buffer blocks 5 are fixed to the corresponding buffer pads 4 by inserting the positioning pins 7 into the positioning holes 6. The positioning pins 7 fix the buffer blocks 5 at different positions on the bottom buffer pads 4, thereby dividing the receiving cavity into chambers of different sizes for placing parts of different specifications. The structure is simple, the chamber size can be easily changed, and the structure of the fixed buffer blocks 5 is stable and not easy to move, avoiding the collision caused by the displacement of the placed parts due to the increase in the size of the chamber. It is suitable for transporting parts of multiple specifications at the same time.

[0019] In this embodiment, as Figure 3 As shown, the buffer pad 4 and the buffer block 5 have the same structure. The buffer pad 4 is made of pearl cotton, EVA foam or silicone. The buffer pad 4 is covered with cotton cloth 8. The cotton cloth 8 on the buffer pad 4 is fixed to the inner wall of the receiving cavity with glue, which effectively prevents the parts from being deformed due to impact during the delivery process and improves the reliability of the delivered parts.

[0020] In this embodiment, as Figure 1 , 2 As shown in Figure 4, a vent hole 9 is provided at the center of the cover 1. The vent hole 9 is a countersunk through hole, with the larger end of the vent hole 9 away from the receiving cavity. A waterproof and breathable membrane 10 is installed inside the vent hole 9 to prevent the humid environment inside the receiving cavity from causing corrosion on the surface of the parts.

[0021] In this embodiment, as Figure 4 As shown, it also includes a dust cover 11. A plastic tube 12 is fixed on the inner arc surface of the dust cover 11. The plastic tube 12 consists of two sections with different outer diameters. The smaller diameter plastic tube 12 is away from the dust cover 11. The smaller diameter plastic tube 12 is detachably installed at the larger end of the vent hole 9. The larger diameter plastic tube 12 is provided with a ventilation hole 13, which reduces the risk of dust falling into the vent hole 9 and clogging the waterproof and breathable membrane 10.

[0022] In this embodiment, as Figure 4 As shown, a shrinkage slit 14 is provided on the small-diameter plastic tube 12. There are several shrinkage slits 14 and they are evenly distributed along the axis of the plastic tube 12. The shrinkage slit 14 narrows the small-diameter plastic tube 12 when it is inserted into the vent hole 9. The shrinking plastic tube 12 generates an expansion force, thereby firmly fixing it in the vent hole 9 and reducing the risk of detachment.

[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
