Device for automatically detecting surface bending resistance of supporting rod of intelligent advertising board

Abstract

The invention relates to the technical field of advertising media, and discloses a device for automatically detecting the surface bending resistance of a supporting rod of an intelligent advertising board. The device comprises a shell, the interior of the shell is movably connected with a rotating lead screw, and the rotating lead screw is connected with an automatic detection mechanism and an automatic anti-rust agent spraying mechanism. After a supporting rod is placed in the device, the rotating lead screw begins to rotate, the rotating lead screw rotates to drive a rod pressing block below the supporting rod to move upwards, at the moment, the rod pressing block presses the supporting rod tightly, pressure continues to be increased, if the supporting rod is bent at the moment, the rod pressing block inclines, the liquid level in the rod pressing block inclines, at the moment, a buoyancy ball in the rod pressing block can move upwards to drive an alarm contact to be in contact with an alarm contact point because of buoyancy increase caused by the increase of the contact volume of the surface and the liquid, and the alarm starts to give an alarm, so that the function of automatically detecting whether the bending resistance of the advertising board supporting rod is qualified or not is achieved.

Description

technical field [0001] The invention relates to the technical field of advertising media, in particular to a device for automatically detecting the bending resistance of the support rod surface of an intelligent billboard. Background technique [0002] In today's social development, advertising media is an inevitable development trend. Through the information interaction of advertisements, it can effectively promote products, increase the popularity of products, and at the same time attract more consumers to buy. At present, the main advertising media The methods include the use of billboards, the display of LED screens and the dissemination of leaflets, the most frequent of which is the use of billboards. [0003] However, when billboards are currently used, the bending strength of the billboards will not meet the standard, which will cause the billboards to bend due to external force during use. The most important thing is that the billboards are oppressed in rainy and sno...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a device for automatically detecting the bending resistance of the support rod surface of an intelligent billboard, which is equipped with automatic detection of the bending strength of the billboard support rod and automatic spraying of antirust agent to prevent the surface of the support rod from being damaged. The advantage of oxidation solves the problem that the bending strength of the billboard is not up to the standard, which leads to the breakage in the later use and the cumbersome and cost-wasting problems of manual spraying of anti-rust agent
