Description

A kind of municipal road management automatic lifting Fast Installation advertisement support frame

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 Fast installing advertisement support frame can be provided with a support top plate in first support plate, be arranged in the support top plate There is the first bull wheel of rotation, so as to can further drive described first to draw by the rotation of first bull wheel The lifting of rope can further make institute so as to be correspondingly connected with using first drawstring later on the fixed base The second support plate is stated to slide on first drawstring, so as to guarantee the normal sliding to second support plate, and The second drawing can be provided on second bull wheel by being provided with the second bull wheel of rotation in the support top plate Rope, so as to which second support plate lifting can be further driven to by the sliding of second drawstring, so as to Second support plate can further facilitate after being elevated on ground replaces advertisement canvas, avoids worker and exists Danger caused by advertisement canvas is replaced under high altitude environment, and the connection screw thread of rotation is provided in first support plate Axis, so as to which further second support plate can be fixed by the rotation of the connection screw thread axis, thus Prevent second support plate from unstable problem, and the control that can be distinguished by the rotating bar occurring in high vacancy The lifting and fixation for making second support plate, are controlled so as to further facilitate using the rotating bar, and The rotation of the third drawstring can be further driven to by the synchronous rotation of the third bull wheel, so as to It is further strained and fixed in second support plate using the third drawstring to what advertisement canvas synchronized, to keep away Trouble caused by artificial fixation of advertisement canvas is exempted from, to further increase working efficiency.

The invention is realized by the following technical scheme:
