Technical field
The present invention relates to a kind of advertisement support frames, and in particular to a kind of municipal road management automatic lifting Fast Installation advertisement
Support frame, more particularly to a kind of municipal road management automatic lifting Fast Installation advertisement for capableing of Fast Installation and replacement billboard
Support frame.
Background technique
The continuous development of advertising sector is also further promoted while not reading and improve with living standard, wherein present
The two sides of life Zhong highway can all be provided with a large amount of billboard, and billboard can be propped up using support tube
Support, so as to which billboard to be supported to certain height, can further facilitate driving vehicle to see to reach and publicize widely
Purpose, wherein since billboard is fixedly mounted on support tube during present billboard installation, due to needing
Advertisement canvas is set on billboard, so pacifying so as to convenient to advertisement canvas with regard to needing to climb to the top of support tube
Dress, and due to the replacement of ad content so with regard to needing frequently to replace advertisement canvas, so just needing worker couple
Advertisement canvas carries out frequent replacement operation, although using manually replacement installation can be carried out to advertisement canvas, there is also
Following problems:
Since support tube has certain height so operation under the high-level environment of worker is just needed, due to high-level
Operation can have certain risk in environment, so certain falling hazard will be caused to worker, and in high altitude operation
In the case where due to job space limitation, and need for advertisement canvas to be fixed on billboard, so replacement advertisement canvas
Certain trouble is brought, the inefficiency of advertisement canvas replacement is further caused.
It is therefore necessary to design a kind of municipal road management automatic lifting Fast Installation advertisement support frame, to solve above-mentioned skill
Art problem.
Summary of the invention
The object of the present invention is to overcome the problems of the prior art, and it is fast to provide a kind of municipal road management automatic lifting
