Mail packaging box capable of avoiding secondary impact

Abstract

The invention relates to the technical field of mail packaging, and discloses a mail packaging box capable of avoiding secondary impact. The mail packaging box capable of avoiding secondary impact comprises a square box body, wherein an open end is arranged on one side of the box body, mounting shafts are mounted at the edges on the periphery of the open end, and each side face on the periphery of the open end is provided with two landing plates. The two adjacent landing plates on every two adjacent side faces are both installed on the mounting shaft between the two adjacent landing plates. Through the arrangement of the landing plates, when one edge of the box body touches the ground, the landing plates on the two sides of the edge touching the ground extend out to make contact with the ground, then the landing plate with the short extending distance slowly retracts, the side face of the box body slowly descends until the landing plates are completely retracted, and then the side face of the box body makes contact with the ground at the moment; and in this way, stable placement of the box body is achieved, secondary impact generated when the side face touches the ground again after the edge touches the ground is avoided, and the damage probability of objects in the mail is lowered.

Description

technical field [0001] The invention relates to the related technical field of mail packaging, in particular to a mail packaging box capable of avoiding secondary impact. Background technique [0002] The development of the e-commerce industry has greatly promoted the development of the express delivery industry. However, at this stage, the service quality of the express delivery industry varies. During the transportation of mail, violent treatment of mail occurs from time to time. Second, in the process of unloading and sorting, the mail is often thrown on the ground, which will cause impact on the items in the package and easily damage the items in the package. The packing box of the mail is generally square, and it will be damaged when the mail is thrown out. During the process, when the side of the packaging box touches the ground, the ground only impacts the mail once, and when the edge of the mail packaging box touches the ground, since only the corners touch the groun...

[0002] The development of the e-commerce industry has greatly promoted the development of the express delivery industry. However, at this stage, the service quality of the express delivery industry varies. During the transportation of mail, violent treatment of mail occurs from time to time. Second, in the process of unloading and sorting, the mail is often thrown on the ground, which will cause impact on the items in the package and easily damage the items in the package. The packing box of the mail is generally square, and when the mail is thrown out and whereabouts During the process, when the side of the box is in contact with the ground, the ground only impacts the mail once, and when the edge of the mail box touches the ground, only the corners touch the ground, the box is unstable, and the box will continue to Flipping to one side in contact with the ground, resulting in two impacts on the mailed item, namely: one impact on the edge and the second impact on the side, so, after the mail is thrown out, the number of impacts on the item caused by the edge It is greater than the number of impacts caused by the direct contact of the surface of the mail with the ground. In order to solve the problem of two impacts caused by the edge landing on the ground, the present invention is proposed
