When the display terminal detects windy, different windproof treatments are carried out according to the wind level: when the wind measured by the wind sensor is smaller, such as 1-4 stages, the brake mechanism in the winding shaft 12 and the brake mechanism on the threaded sleeve 24 are in a closed state, at the moment, the support rod 2 of the display terminal is reset only by virtue of the self-adaptive locking mechanism 5, when the support rod 2 is bent under the action of wind force, a deformation force inserted into the damping ring 15 through the conical limiting block generates a driving source for resetting the support rod 2, and the restoring force can be provided through elastic deformation of the structure due to smaller wind force; when wind is large, for example, 5-7 stages, a brake mechanism on the threaded sleeve 24 is opened, at the moment, the supporting rod 2 is bent by the large wind to drive the adjusting rope to move upwards, so that the driving sleeve 23 is driven to move downwards, the linkage rod 19 is spread, wind force is stored in the shrinkage framework 13, and after the wind force is small, the shrinkage framework 13 is shrunk to drive the adjusting rope 11 to reset; the two action modes do not need to provide external force drive, the windproof effect can be realized by only using wind power, the structure is simple, and the energy is saved; when the wind power is large, for example, in the 8-13 level, at this time, the brake mechanism in the winding shaft 12 and the brake mechanism on the thread sleeve 24 are both in an open state, and meanwhile, the winding shaft 12 acts, and the effect of resetting the display terminal is achieved by pulling the adjusting rope 11. Because be provided with the spacer pin on one of a plurality of articulated bars, simultaneously, be provided with the spacing groove on corresponding joint nest, consequently, when articulated bar takes place to crookedly, drive articulated bar takes place to rotate along self axis to make screen 1 can rotate certain angle, preferably 90 degrees, so that screen 1 receives wind-force influence minimum, after wind-force reduces, articulated bar 7 resets again, spacing groove and spacer pin cooperation drive screen 1 again around the opposite direction rotation of articulated bar axis reset, thereby reach the automatic re-setting effect.
As can be seen from the above description, according to the self-adaptive media publishing system, since the display terminal is provided with the wind-proof devices with different levels according to the wind force in the environment, the display terminal can be more suitable for the environment, and meanwhile, in the provided wind-proof devices, the initial installation position of the device can be selected according to the installed environment, so that the universality of the equipment is further improved; meanwhile, the locking mechanism is creatively arranged into a structure with the shape capable of being changed according to the wind power, and more restoring force can be provided while energy is stored; further, through setting up spacer pin, spacing groove on the articulated pole to set up the spacing groove into space three-dimensional structure, make the articulated pole when receiving the strong wind influence to take place to bend, can take place to rotate along the articulated pole axis, and then will screen 1's less atress face changes the great direction of wind-force. Compared with the existing windproof advertising device, the windproof advertising device is novel in structure, scientific in setting, energy-saving and higher in universality.
