It is equipped with torsional spring, which is arranged around trunnion axis, and end is fixedly connected respectively at trunnion axis with rotating casing, so that turning set
Pipe can set back after turning an angle around trunnion axis under the effect of the torque of torsional spring；The steel of the elastic mechanism
Pedestal is fixed on rotating casing, and be provided on closure length direction and trunnion axis it is axially vertical through slot, institute
The steel attachment base for stating elastic mechanism is passed through and should be cooperatively connected after slot with steel pedestal, to be steel attachment base and steel
Pedestal drives rotating casing rotation to provide surplus.
In the present invention, the preparation method of the resilient sleeve is：
1）Firstly, selecting symmetrical two pieces of stripe boards and two pieces of rectangular slabs, one piece of stripe board is bonded on a horizontal base plate, and
Two pieces of rectangular slabs and the both ends of the stripe board are adhesively fixed again afterwards, thus on horizontal base plate formed one "] " shape；
2）The spring of several equal lengths is bonded on the surface of another piece of stripe board, after bonding, by the two of the stripe board
End with "] " two pieces of rectangular slabs in shape are adhesively fixed, and make the spring free end of its surface bonding resist another piece "] " item in shape
The surface of shape plate, to form the internal bar shaped cavity that several springs are distributed with；
3）Natural rubber is melted in mixer, it is then filled into the bar shaped cavity by the opening of bar shaped cavity top
Interior, natural cooling is to form the internal strip-shaped rubber plate comprising spring；
4）The both ends of the strip-shaped rubber plate length direction are bonded together and form resilient sleeve.

The fixed sleeving clearance fit of variable information back can be around to make variable information board when by big wind blows
Lower fixed link rotates certain angle, and then reduces the wind surface of variable information board, reduces windage, improves wind resistance energy
Power；
Due to being equipped with resilient sleeve and rubber sleeve in the steel sleeve in elastic mechanism, and several cyclic annular gold are arranged on connecting column
Belong to plate, these annular metal sheets are adjacent to rubber sleeve, when encountering strong wind weather, will receive since variable information plate suqare is larger big
Windage, so that resistance is transmitted on connecting column by crossbeam, since connection column bottom is the cylinder for being threaded through steel pedestal
In shape channel, though position is defined but still has certain activity surplus, and upper part passes through ring-type under the action of the wind
Metal plate generates squeezing action to resilient sleeve and rubber sleeve, thus the whole micro inclination for generating certain angle, and then make can be changed
Advices plate also generates certain tilt angle, reduces the effect of wind-force；Since resilient sleeve is internally provided with spring, by crowded
Certain restoring force can be generated after pressure, so that annular metal sheet reset can be passed through after ensure that wind-force reduces；
Meanwhile coaxial relatively turnable rotating casing and trunnion axis are provided in firm banking, and between the two with torsion
Spring connection, after the steel pedestal in elastic mechanism is fixed on rotating casing, once wind-force is excessive, can make variable information board
Wind-force is passed into rotating casing by upper fixed link, connecting column, steel attachment base and steel pedestal, and then makes rotating casing gram
The elastic force for taking torsional spring turns an angle, and tilts variable information board, reduces wind surface；And make in wind-force reduction, torsional spring can band
Dynamic rotating casing sets back, to maintain the vertical of variable information board under normal condition；
2）In the present invention, in order to reduce the temperature under high temperature in variable information board, the shell of variable information board is arranged to have
The rectangle frame of rectangular ring cavity, and the curved reflection cover of arc is set to emit certain heat, curved reflection on top
Also there is gap, to reduce the transmitting of heat between cover and shell；The maintenance door of enclosure interior LED display panel and the back side
Between there is porous separator, so that the heat for enabling electronic device to generate is dissipated by shutter on demarcation plate and maintenance door
It sends out；In order to realize dust reduction capability, the second dust excluding plate of L-shaped first dust excluding plate and inverted L-shaped is set in maintenance door, this two
Block dust excluding plate forms the continuous inverted U-shaped channel being connected to shutter, and felt layers are arranged in this channel, to carry out to floating ash
Absorption, it is therefore prevented that most of dust enters enclosure interior by shutter；
3）In order to improve heat dissipation effect, column and lower fixed link are hollow tubular structure by the present invention, and the bottom of column is solid
It is scheduled on and is carried out in closed melt pit by cover board, be provided with exhaust fan in column, the air inlet of exhaust fan is by the cold sky in melt pit
Gas extraction is sent in column, and along the rectangular ring cavity that column and lower fixed link are sent to shell, and then by ventilative
Channel, which enters to have in cavity between LED display panel and demarcation plate, cools down to electronic component；In order to prevent in hole
Exhaust fan is flooded after water inlet, the position of exhaust fan can be arranged in the higher position of column internal ratio, but not depart from melt pit
Range.
