Letter box device convenient to use

Abstract

The invention discloses a letter box device convenient to use. The letter box device convenient to use comprises a pedestal and surrounding devices which are distributed on the top end face of the pedestal at equal intervals. The bottom of the pedestal is fixedly provided with a flexible cushion. The part, under each surrounding device, of the pedestal is internally provided with a drive cavity which extends towards the front side, wherein the rear side of the drive cavity communicates with a first hollow cavity which extends leftwards and rightwards, the part, on the front side of the first hollow cavity, of the pedestal is internally provided with a second hollow cavity, and a partition plate is arranged between the first hollow cavity and the second hollow cavity. The inner top of the front side of each first hollow cavity is provided with a guide groove, and each guide groove is internally provided with a first sliding frame which extends downwards. The letter box device convenientto use is simple in structure, installation of a plurality of surrounding cylinders can be achieved, it does not need to change the surrounding cylinder after one surrounding cylinder is wound, timeand labor are saved, and the efficiency is improved; and in addition, it does not need to additionally arrange a drive device, the manufacturing cost is reduced, and meanwhile the purchasing cost is reduced for an enterprise.

Description

technical field [0001] The invention relates to the field of letterbox processing, in particular to a convenient letterbox device. Background technique [0002] The exterior of the letterbox body needs to be painted, so that the exterior of the letterbox can be more beautiful and corrosion resistant. When it is necessary to paint around the letterbox body, workers usually manually move and rotate the letterbox body, which is laborious. There is also a machine that automatically wraps the cabinet through the wrapping device. The existing wrapping device often only wraps a single wrap, and the work efficiency is low. After wrapping one wrap, the mailbox box needs to be disassembled, and then continue wrapping, which is a waste of man-hours and low in efficiency. Low, in addition, if you want to install more surround devices, you need to install additional drive devices, which increases the cost and is very inconvenient to use.
