AI Technical Summary
During the transportation process, the existing plastic packaging boxes for metal parts transport have severe shaking due to excessive quality of the items, which increases wear of the metal parts, and the locking structure cannot meet the needs of high-weight items.
A plastic packaging box for transportation of metal parts is designed, using hinges to connect the main body and the box cover, and a plastic pad is installed at the four corners to cushion and shake. The box is equipped with an inner liner and a soft rubber layer to absorb shock. The lock is composed of a pin, a wrench, an elastic member, a bump and a limiting groove, which enables a firm connection through simple structure and operation.
Through the buffering effect of the soft rubber layer and plastic pad, the box is less shaken during transportation and handling, the wear of metal parts is reduced, and a firmer connection is achieved through the improved locking structure to ensure the safe transportation of metal parts.

Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of packaging boxes, and in particular to a plastic packaging box for transporting metal parts. Background Art
[0002] Plastic packaging boxes for transporting metal parts are efficient and safe packaging solutions made of high-strength plastic materials. They are lightweight, durable, easy to clean and affordable. They comply with international logistics standards and are easy to stack and carry. They are widely used in multiple industrial fields, providing reliable protection for the safe transportation of metal parts.
[0003] Since plastic packaging boxes for transporting metal parts are used to transport metal parts, the high mass of the items being transported may cause severe shaking during transportation, making the box unstable and increasing the wear of the metal parts.
[0004] On the other hand, the locks of common plastic packaging boxes only use a simple connection structure, which often cannot meet the required connection requirements when facing heavy items such as metal parts. Summary of the invention
[0005] In view of the above problems existing in the prior art, a plastic packaging box for transporting metal parts is now provided.
[0006] The specific technical solutions are as follows:
[0007] A plastic packaging box for transporting metal parts is designed, comprising a main body and a box cover, wherein hinges are provided on one side of the main body and the box cover, the hinges respectively fix the main body and the box cover, the box cover is connected to the main body through the hinges, plastic pads are provided at four corners of the main body and the box cover, the plastic pads are fixedly connected to the main body and the box cover, handles are provided at both ends of the main body, the handles are fixedly connected to the main body, and a lock is provided on one side of the main body and the box cover away from the hinge, and the upper and lower parts of the lock are respectively connected to the main body and the box cover.
[0008] Preferably, an inner liner is provided in the main body, the inner liner is fixedly connected to the main body, a soft rubber layer is provided between the inner liner and the main body, the soft rubber layer is fixedly connected to the inner liner, and the soft rubber layer is higher than the main body and the inner liner.
[0009] Preferably, a groove is provided on one side of the box cover close to the main body.
[0010] Preferably, the lock is composed of a latch, a wrench, an elastic member, a protrusion and a limiting groove, wherein the protrusion is arranged in the limiting groove, and the elastic member is fixedly connected to the wrench.
[0011] Preferably, the hinge is fixedly connected to the main body and the box cover by a fastener.
[0012] The above technical solution has the following advantages or beneficial effects:
[0013] 1. Through the coordination of the main body, liner, soft rubber layer and plastic pad, the soft rubber layer can buffer and unload the fluctuations generated during transportation from the inside, and the plastic pad can buffer the outside, thereby reducing the shaking of the box during transportation and handling, thereby reducing the wear on metal parts.
[0014] 2. Through the coordination of the provided latch, wrench, elastic member, protrusion and limit groove, when the box cover is closed, the upper and lower parts of the lock intersect, and the wrench is rotated by force at this time, and is affected by the limit groove and the protrusion. When it is rotated to a certain angle, the latch can be inserted into each other. After the latch is inserted, the elastic member pulls the wrench back to its original position to lock the lock to complete the fixation. When the packaging box needs to be opened, it can be unlocked by simply pulling the wrench. Through the above structure, a more secure connection method can be achieved with simple structure and operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.
[0024] Reference Figure 1-4 A plastic packaging box for transporting metal parts comprises a main body 1 and a box cover 2, wherein a hinge 9 is provided on one side of the main body 1 and the box cover 2, the hinge 9 fixes the main body 1 and the box cover 2 respectively, the box cover 2 is connected to the main body 1 through the hinge 9, plastic pads 4 are provided at the four corners of the main body 1 and the box cover 2, the plastic pads 4 are fixedly connected to the main body 1 and the box cover 2, handles 8 are provided at both ends of the main body 1, the handles 8 are fixedly connected to the main body 1, a lock 3 is provided on the side of the main body 1 and the box cover 2 away from the hinge 9, the upper and lower parts of the lock 3 are respectively connected to the main body 1 and the box cover 2, through the above structure, the shaking of the box during transportation and handling can be reduced, thereby reducing the wear on the metal parts and a more secure connection method can be achieved with a simple structure and operation.
[0025] Furthermore, an inner liner 5 is provided in the main body 1, and the inner liner 5 is fixedly connected to the main body 1. A soft rubber layer 6 is provided between the inner liner 5 and the main body 1, and the soft rubber layer 6 is fixedly connected to the inner liner 5. The soft rubber layer 6 is higher than the main body 1 and the inner liner 5. By adding the soft rubber layer 6 in the interlayer, shock absorption can be performed from the inside.
[0026] Furthermore, a groove 7 is provided on one side of the box cover 2 close to the main body 1. By inserting the part of the soft rubber layer 6 that is higher than the main body 1 and the inner liner 5 into the groove 7, it can play the role of a sealing rubber ring to prevent the metal parts from getting wet.
[0027] Furthermore, the lock 3 is composed of a latch 301, a wrench 302, an elastic member 303, a protrusion 304 and a limiting groove 305, wherein the protrusion 304 is arranged in the limiting groove 305, and the elastic member 303 is fixedly connected to the wrench 302.
