The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic structural view of a sleeved flexible-wing antiglare shield according to an embodiment of the present invention; FIG. 2 is a bottom side view of a flexible shade wing provided by embodiments of the present invention; FIG. 3 is a schematic diagram of components provided by an embodiment of the present invention; FIG. 4 is a bottom side view of a sleeved flexible-wing antiglare shield according to an embodiment of the present invention. Referring to fig. 1 to 4, the dazzle prevention plate includes: the flexible shading wing 1, the upright post 2 and the bottom plate 3; the flexible shading wings 1 are connected double wings, and a cavity column sleeve 4 is arranged in the middle; the root of the upright post 2 is welded with an upright post hole 5 on the bottom plate 3; the stud 2 is inserted through the bottom hole 6 of the hollow sleeve 4.

Wherein, the upright post 2 is welded with the upright post hole 5 on the bottom plate 3 to form a supporting upright post with stronger wind load resistance and torsion resistance; the top end of the upright post 2 is inserted from the bottom hole 6 of the cavity post sleeve 4, so that the dazzling prevention purpose can be realized for vehicles on lanes on two sides through the flexible shading wings 1, the influence of vehicle light which is prevented from being driven from the opposite side can be realized during driving at night, and the safety is greatly improved.

The flexible light-shielding wing 1 is made of a flexible material having a certain toughness and capable of bending with wind to a certain extent, and has the properties of acid and alkali corrosion resistance, ultraviolet resistance, aging resistance, freezing resistance and heat resistance. For example: rubber, and the like. Therefore, the flexible shading wing 1 can be bent to a certain extent along with wind when strong wind blows, so that wind resistance damage is reduced, and formation of resonance waves between plate bodies can be avoided. And the double wings and the cavity column sleeve 4 in the flexible shading wing 1 are integrally formed through a mould, and pigment can be added during production, so that the color spraying treatment on the outer surface of the flexible shading wing at the later stage is avoided. Secondly, the upright post 2 and the bottom plate 3 are made of metal materials with the same material quality, so that welding is facilitated; when the upright post 2 and the bottom plate 3 are made of metal materials, the hot galvanizing corrosion prevention treatment is required according to the highway facility specification. The column 2 and the bottom plate 3 may be formed integrally by molding a hard material such as resin of the same material in one step.

Further, the upright post 2 is a hollow tube which is gradually enlarged from top to bottom and has an oval or polygonal cross section.

It should be noted that, the upright column 2 is set to be a hollow tube with an oval or polygonal cross section, which is gradually enlarged from top to bottom, so that the overall strength is high, and the cavity can absorb a large part of road vibration waves, thereby eliminating the hidden danger of damage to the flexible wing anti-glare panel caused by the vibration waves. And secondly, the flexible shading wing 1 of the anti-dazzle plate has better supporting resistance when being attacked by strong wind at the front, and has stronger torsion resistance when being attacked by strong wind at the side surface. Furthermore, the cross section of the upright post hole 5 on the bottom plate 3 is set to be the same as that of the upright post 2, and the upright post hole 5 is slightly larger than the root part of the upright post 2, so that the root part of the upright post 2 can be inserted into the upright post hole 5 for annular welding.

In addition, during actual installation, the narrow end of the elliptic cross section of the upright post 2 is in the same direction as the road, the two wings of the flexible shading wing 1 form an angle of 90 degrees with the road, when the flexible shading wing 1 is attacked by strong wind on the side, one side is stressed and bent, when the flexible shading wing 1 is attacked by strong wind on the front side, the two sides are stressed and bent synchronously, and compared with the traditional antiglare shield, the flexible shading wing has a better wind discharging effect.

Further, the cavity column sleeve 4 is a cavity column sleeve which is gradually enlarged from top to bottom and the cross section of which is oval or polygonal. It should be noted that, the cavity column sleeve 4 is also set to be gradually enlarged from top to bottom, and the cross section of the cavity column sleeve is an oval or polygonal cavity column sleeve, so that the inner cavity of the cavity column sleeve 4 is matched with the outer wall of the upright post 2, and thus, various destructive forces received by the rigid upright post 2 are transmitted to the two wings of the flexible shading wing 1 through the cavity column sleeve 4, and further, the destructive forces are completely released. .

In addition, the inner aperture, the taper and the height of the cavity column sleeve 4 are the same as the diameter, the taper and the height of the outer wall of the upright post 2, the cavity column sleeve 4 is sleeved downwards from the upper end of the upright post 2 during installation, when the cavity column sleeve is close to the bottom of the upright post 2, the contact surface between the inner wall of the cavity column sleeve 4 and the outer wall of the upright post 2 can be tightly attached by slightly applying force, and the cavity column sleeve is more beneficial to detachment.

Furthermore, a limiting hole 7 is longitudinally arranged on the cavity column sleeve 4; a limiting pin hole 8 is longitudinally arranged on the upright post 2; the position of the limiting hole 7 corresponds to that of the limiting pin hole 8, and the limiting hole 7 is connected with the limiting pin hole 8 through a limiting pin 9.

It should be noted that a plurality of limiting holes 7 are longitudinally arranged on the cavity column sleeve 4, a plurality of limiting pin holes 8 are longitudinally arranged on the column 2, and the limiting holes 7 correspond to the limiting pin holes 8 in position and are the same in number. After the hollow column sleeve 4 is sleeved into the upright column 2, the limiting hole 7 is connected with the limiting pin hole 8 through the limiting pin 9; the aim is to further avoid that when the flexible shading wing 1 is in a strong wind environment, the cavity column sleeve 4 horizontally swings on the upright column 2, so that the installation direction of the flexible shading wing 1 deviates; another object is that the flexible shade wing 1 will expand or contract slightly due to the change of air temperature, so as to control the over-displacement in the longitudinal direction.

In addition, a flat pad (not shown in the figure) can be arranged on the contact surface of the limit pin 9 and the cavity column sleeve 4. Because the cavity column sleeve 4 and the upright post 2 are of a cone structure gradually changing from top to bottom, the length of each limiting pin 9 is different and corresponds to the installation part of the limiting pin, and the length of each limiting pin 9 is slightly larger than the thickness of the cavity column sleeve 4 sleeved with the upright post 2, so that the contact surfaces of flat pads at two ends of each limiting pin 9 and the outer wall of the limiting hole 7 on the cavity column sleeve 4 cannot be too tight, and the cavity column sleeve 4 can also conform to the physical changes of the flexible shading wings 1 when the flexible shading wings expand when heated and contract when cooled.

Furthermore, the root parts of the two wings of the flexible shading wing 1, which are connected with the cavity column sleeve 4, are gradually thinned outwards. Therefore, the outer edges of the two sides of the flexible shading wing 1 are bent to a certain extent along with the direction of the incoming wind, so that the wind resistance is reduced, and the purposes of weakening the wind attack strength and prolonging the service life are achieved.

Further, a plunger 10 is connected to the top end of the upright post 2. So that rain, snow and moisture can be prevented from entering the cavity of the upright post 2 and corroding the upright post 2.

Further, the bottom plate 3 is also provided with bolt holes 11. Thus, the bottom plate 3 can be mounted on the base by bolts, so that the antiglare shield is more firmly mounted.

The complete work flow of the invention can be as follows: firstly, inserting the bottom end of an upright post 2 into an upright post hole 5 of a bottom plate 3, and circumferentially welding, and ensuring that the longitudinal center line of the upright post 2 is vertical to the plane of the bottom plate 3; then the upright post 2 is inserted into the bottom hole 6 of the hollow post sleeve 4, the narrow end of the oval cross section of the upright post 2 is in the same direction with the road, and the two wings of the flexible shading wing 1 form an angle of 90 degrees with the road; then, inserting a limit pin 9 into a limit hole 7 longitudinally arranged on the cavity column sleeve 4 and a limit pin hole 8 on the upright post 2; then the lower end of the plunger 10 is inserted into the hole at the top end of the upright post 2 and fastened, and finally the bolt hole 11 on the bottom plate 3 is fixed on the base by using a bolt.

Another installation method can be as follows: firstly, the bottom end of an upright post 2 corresponds to an upright post hole 5 in a bottom plate 3, the upright post hole is inserted into the upright post hole for circumferential welding, and the bottom plate 3 is fixed on a base through bolts; then, a bottom hole 6 at the bottom of the cavity column sleeve 4 is downwards sleeved on the outer wall of the upright post 2 from the top end of the upright post 2, so that the inner cavity of the cavity column sleeve 4 is ensured to be tightly attached to the outer wall of the upright post 2, a limiting hole 7 longitudinally arranged on the cavity column sleeve 4 is enabled to be consistent with a hole position of a limiting pin hole 8 longitudinally arranged on the upright post 2 at intervals, the oval narrow end of the cross section of the upright post 2 is ensured to be in the same direction as a road, and the two wings of the flexible shading wing 1 form an angle of 90 degrees with the road; then, the limiting pins 9 with different lengths are respectively inserted into the limiting pins for fixing, and finally, the lower end of the plunger 10 is inserted into the hole at the top end of the upright post 2, so that all parts are installed.

The description needs to be shown, and is verified: when the wind direction and the shading surface of the anti-dazzle plate form an included angle of more than 15 degrees and less than 90 degrees, resistance is generated; when the included angle is 25-55 degrees, the resistance is the largest; when the included angle is smaller than 25 degrees and larger than 55 degrees, the wind resistance of the shading surface is gradually weakened. The traditional anti-dazzle plate is easy to damage mainly due to overt strong wind attack, hidden resonance waves and vibration waves, weak wind and excessive fatigue of the middle lower part of a plate body caused by driving airflow in vehicle running, and the result is physical damage caused by various comprehensive factors; another hidden injury to the base of a glare shield of metallic material is damage from salt and alkali etching. Secondly, the installation form of the anti-dazzle plates with a plurality of anti-dazzle plates on the same cross beam frame is common at present, the whole body of the common anti-dazzle plate is of a hard rigid structure, approximate or same resonance frequency is easy to generate under the action of weak wind and vibration waves, and in addition, the mutual transmission of various stresses on the cross beam is difficult to release; and because the weight of the steel plate series anti-dazzle plate monomer is larger, and a plurality of plate bodies are connected, the stress and the stress are concentrated on the root, and the series damage is easily caused.

In addition, when vehicles run in opposite directions on respective lanes at night, the irradiation distance of the high beam of the vehicles is long, and the included angle between the light source of the high beam and the sight line of drivers and passengers in the vehicles running on the opposite roads is less than 8 degrees, glare pollution is the strongest. At this time, two vehicles traveling at high speed enter an absolutely dangerous place instantaneously for several seconds, and the distance is 50 to 300 meters. Therefore, the glare pollution to the car lights can be effectively eliminated by arranging the glare shield which forms an angle of 90 degrees with the road direction, has an interval of one meter and one seat and has the minimum width of not less than 150mm in the isolation belt of the expressway. Even in the strong wind night weather, although the flexible shading wings can bend to a certain extent along with the direction of the incoming wind, no matter the front surface or the side surface of the flexible shading wings encounters the incoming wind, the shading included angle can be completely ensured to be larger than 8 degrees, and the effect of shading glare pollution can be fully exerted.

It is worth to be noted that the invention is provided with the upright post, the bottom plate and the flexible shading wing, and the upright post and the bottom plate are welded to form the supporting upright post with stronger wind load resistance and torsion resistance; the upright post is sleeved in the cavity post sleeve of the flexible shading wing, and the upright post and the flexible shading wing are matched with each other, so that the wind resistance damage can be weakened, and the formation of resonance wave between plate bodies can be avoided. Secondly, the upright post is arranged into a hollow pipe which is gradually enlarged from top to bottom and has an oval or polygonal cross section, so that the damage of vibration waves generated by the friction between the vehicle tire and the road surface can be eliminated; and the production process is simple and the equipment investment is low.

Thirdly, limiting holes are longitudinally formed in the cavity column sleeve, and limiting pin holes are longitudinally and correspondingly formed in the upright column and connected through limiting pins; on one hand, the horizontal swing of the cavity column sleeve on the upright column when the flexible shading wing is in a strong wind environment can be avoided, so that the installation direction of the flexible shading wing is deviated; on the other hand, the cavity column sleeve which can conform to the flexible shading wing expands or contracts in hot and cold environments. In addition, the invention has simple structure, light weight, low price, convenient installation and transportation and can greatly reduce the cost of labor, transportation and materials.
