Novel letter box device

Abstract

The invention discloses a novel letter box device. The novel letter box device comprises a vehicle frame body and a shell cover fixedly installed in the vehicle frame body. Leg pillars are fixedly installed at the four vertex corners of the bottom end face of the vehicle frame body, and antiskid pads are arranged at the bottom end faces of the leg pillars in an adhesive mode. A main cavity is formed in the shell cover. A drilling device is arranged in the position, on the left side of the main cavity, of the shell cover. The drilling device comprises a first sliding cavity formed in the shellcover and a sliding block arranged in the first sliding cavity in horizontal sliding fit and connection modes. A first through hole penetrating through the bottom end face of the shell cover is formedin the inner bottom wall of the left side of the first sliding cavity. A drilling pillar extending upwards is connected in the first through hole in a transitional fit mode. The novel letter box device is simple in structure and convenient to operate, the labor intensity of workers is relieved, the construction efficiency is improved, and the construction progress of letter box processing is greatly accelerated.

Description

technical field [0001] The invention relates to the technical field of letterbox processing, in particular to a novel letterbox device. Background technique [0002] After the letterbox body is produced, processed and shaped, text and pictures are usually marked on the outer surface of the letterbox, such as production date, product number, etc. The existing letterbox marking equipment has high manufacturing cost and single function. When it is necessary to carry out the drilling operation on the letter box body, additional drilling equipment needs to be purchased, thus increasing the equipment purchase cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new type of mailbox device, which can solve the above-mentioned problems in the prior art. [0004] The present invention is achieved through the following technical proposals: a novel letterbox device of the present invention includes a frame body and a she...
