Convenient-to-replace advertising board device

Abstract

One or more embodiments of the specification provide a convenient-to-replace advertising board device. The advertising board device comprises a main board body, a plurality of sub-board bodies are adjacently arranged in the main board body, a printing cavity is slidably connected to the front end in the sub-board body at the top row, a remote printer is arranged in the printing cavity, and a display cavity is slidably connected to the front end in the sub-board body below the printing cavity. The remote printer receives a remote printing signal to start to print a new hard paper sheet, meanwhile, the printing cavity is triggered and pushed out, the display cavity at the topmost end is triggered and pushed out, the hard paper sheet falls off, a weight sensor is triggered, a display cavity at the adjacent lower side is correspondingly triggered and pushed out, an abutting block is driven to abut against the hard paper sheet again to form a new complete advertising board through splicing, meanwhile, a movable lock catch is connected between a perspective plate and the display cavity, a telescopic column body is fixedly supported at the bottom end of the main board body, and a telescopic mechanism is arranged in the telescopic column body to facilitate adjustment and maintenance.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of billboard equipment, and in particular, to a billboard device that is easy to replace. Background technique [0002] Billboards are the inevitable product of the commodity society, and can play the role of conveying information and promoting commodities. However, existing billboard devices, especially large outdoor billboard devices, are often single in form and simple in function. They are usually designed as a single upright support frame, so that a large billboard with a whole face is fixed on the top of the support frame, so that when replacing and maintaining , it is necessary to manually climb to a high place to replace the entire large billboard, which is obviously a waste of manpower and material resources, time-consuming and labor-intensive operation, and there is a certain risk factor, and the production, transportation, installation, recycling and other processes ...

AI Technical Summary

Problems solved by technology

However, existing billboard devices, especially large outdoor billboard devices, are often single in form and simple in function. They are usually designed as a single upright support frame, so that a large billboard with a whole face is fixed on the top of the support frame, so that when replacing and maintaining , it is necessary to manually climb to a high place to replace the entire large billboard, which is obviously a waste of manpower and material resources, time-consuming and labor-intensive operation, and there is a certain risk factor, and large billboards are in the process of production, transportation, installation, recycling, etc. Both have the problems of difficult operation and high cost, and the core concept of billboards is to attract people's attention and attention, and this traditional display and replacement form is often not enough to further enhance the viewing and attractiveness of billboards. force
