Safe mailbox device

Abstract

The invention discloses a safe mailbox device. The safe mailbox device comprises a base and an accommodating bin, wherein the accommodating bin is arranged in the base and penetrates through front andback. A first arc-opening groove is arranged in the middle end of the bottom side wall of the accommodating bin. A left sliding-moving groove and a right sliding-moving groove are oppositely and correspondingly arranged on the top of the left side wall of the accommodating bin and the upper part of top of the right side wall of the accommodating bin. A through groove is formed in the top side wall of the accommodating bin, and the through groove is connected with the left sliding-moving groove and the right sliding-moving groove. A base plate capable of sliding and moving up and down is arranged in the accommodating bin. A protruding lower block is arranged at the middle end of the bottom part of the base plate, and a second arc-opening groove is arranged in the bottom part of the protruding lower block. According to the safe mailbox device, the structure is reasonable, operation is simple, carrying is convenient, clamping of the mailbox is safe and stable, skewing of the mailbox doesnot occur, following code-spraying operation is conveniently achieved, mailbox with different sizes can be clamped at the same time, clamping fixing cost of the mailbox is significantly reduced, andthe convenient mailbox device is suitable for popularization and usage.

Description

technical field [0001] The invention relates to the technical field of mailboxes, in particular to a safe mailbox device. Background technique [0002] The mailbox is an important carrier for the post office to receive mail.

[0002] The letterbox is an important carrier for the post office to receive mail. Before the letterbox is put into use, the surface of the letterbox will be marked with a code to better count and identify the letterboxes. Most of the existing letterboxes are cylindrical, and the cylindrical letterbox It also includes a variety of letter boxes with different diameters. When spraying the letter boxes, it is usually necessary to fix the letter boxes in order to better complete the inkjet operation. However, the existing fixing devices can no longer meet the needs of fixing various letter boxes with different diameters. But only the letterboxes of the same diameter can be fixed, which reduces the coding work of the letterboxes. Therefore, the existing fixing devices can no longer meet the existing use requirements.
