[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Embodiment 1: This embodiment is used to solve the problem that the direct illumination of vehicle driving lights affects the full coverage of anti-glare shielding that cannot be achieved only by a guardrail with a fixed height.

[0029] Please refer to Figure 1 - Figure 8 As shown in, this embodiment is a foldable road construction anti-glare device, including a combined base 1 and a bottom anti-glare structure arranged above the combined base 1. Columns 2 are arranged on both sides of the upper end of the combined base 1, and the bottom anti-glare structure is installed on the outer sides of both ends of the columns 2. The bottom anti-glare structure includes an upper grid 3 and a lower grid 4, and anti-glare curved rods 5 are vertically installed on both the upper grid 3 and the lower grid 4;

[0030] The top of the bottom anti-glare structure is hinged with a top anti-glare structure. The top anti-glare structure includes a folding bottom frame 6 and a folding top frame 7. Both the folding bottom frame 6 and the folding top frame 7 are vertically installed with additional curved rods 8. The combined base 1 includes a base platform 11 provided on the ground, and a support boss 13 connected to the bottom anti-glare structure is installed on the base platform 11.

[0031] Both the upper grid frame 3 and the lower grid frame 4 are right trapezoid structures and are inserted into each other. The upper grid frame 3 and the lower grid frame 4 together form a square frame structure. An inclined insertion rod 31 is installed at the lower end of the upper grid frame 3, an inclined insertion slot 41 matching the inclined insertion rod 31 is opened at the upper end of the lower grid frame 4, and a limit block for blocking the inclined insertion rod 31 is installed at the bottom of the lower grid frame 4 corresponding to the inclined insertion slot 41.

[0032] The upper end of the column 2 extends to the outside of the folding bottom frame 6 and is installed with a locking rod 21 through it. The locking rod 21 penetrates through the column 2 and is inserted into the folding bottom frame 6. The lower end of the folding bottom frame 6 is hinged to the upper grid frame 3 through a hinge, and an adsorption rod 61 that fits with the upper grid frame 3 is installed at the other end of the folding bottom frame 6 corresponding to the hinge.

[0033] Basic principle: Please refer to Figure 1 - Figure 3 As shown in the figure, replace and install this anti-glare device with the original road guardrail. At this time, the combined base 1 constitutes the base part of the guardrail, and the grid structure constitutes the enclosure part of the guardrail, and the enclosure part provides an anti-glare function.

[0034] During specific use: When applied to the installation on a slope section, set the entire anti-glare device in the original place of the road guardrail. At this time, set the additional height of the top anti-glare structure according to the traffic flow direction of the road. The specific operation is as follows: First, the folding bottom frame 6 and the folding top frame 7 in the top anti-glare structure are jointly flipped above the bottom anti-glare structure, and the two sides are inserted and locked by using the locking rod 21. At this time, the top anti-glare structure composed of the folding bottom frame 6 and the folding top frame 7 is vertically overlapped on the upper grid frame 3 and the lower grid frame 4, constituting an anti-glare range that is twice the initial height. At this time, no matter which direction the vehicle is driving on either side of the road, a full-range anti-glare effect for the blocked area is obtained, and thus the anti-glare setting of the anti-glare device on the slope section is completed.

[0035] It should also be supplemented and explained that: According to actual needs, when setting the top anti-glare structure, it is also possible to set whether to add the folding bottom frame 6 and the folding bottom frame 7. That is, when the folding bottom frame 6 is flipped above the upper grid frame 3, it is possible to choose not to install the folding bottom frame 7. And for the initial installation of the guardrail, according to the traffic flow direction, select the orientation of the inclined insertion slot 41 on the lower grid frame 4 / the folding bottom frame 6, so that the inclined insertion slots 41 on the lower grid frame 4 and the folding bottom frame 6 are arranged away from the traffic flow direction, so that when the vehicle is moving forward, the state changes from the glare state to the anti-glare state, thereby reducing the glare effect of the oncoming vehicle's lights.

[0036] In summary, it can be adaptively set according to the traffic flow direction, and the comprehensive anti-glare purpose is achieved by setting the bottom anti-glare normally and adding a folding anti-glare structure at the top.

[0037] Embodiment 2: This embodiment is used to solve the problem of how to stably set the bottom structure when the anti-glare device is applied to the installation of road guardrails.

[0038] Please refer to Figure 3 、 Figure 6 and Figure 8 As shown in the figure, a folding road construction anti-glare device in this embodiment includes a placement groove 12 opened on a base 11 for inserting a support boss 13. An installation cover 15 is covered and installed on the support boss 13. The support boss 13 and the installation cover 15 jointly open a locking hole 14 horizontally. A vertical insertion hole 18 perpendicular to the locking hole 14 is opened longitudinally on the support boss 13. A longitudinal rod 16 is inserted into the vertical insertion hole 18, and a transverse rod 17 corresponding to the locking hole 14 is inserted on the longitudinal rod 16;

[0039] Please refer to Figure 3 and Figure 8 As shown in the figure, the bottom anti-glare structure and the top anti-glare structure are jointly arranged above the combined base 1. The base 11 in the combined base 1 is installed in the middle of the road through concrete, and then the support boss 13 is clamped in the base 11 to complete the pre-installation of the entire support structure. Then, according to the actual anti-glare requirements, the bottom anti-glare structure and the top anti-glare structure are jointly installed according to the orientation requirements of the inclined slots 41 on the lower net rack 4 / folding bottom rack 6;

[0040] During installation: First, the combined clamping installation of the installation cover 15 is carried out, and the longitudinal rod 16 and the transverse rod 17 are used together to complete the locking and fixing between the installation cover 15 and the support boss 13. Since the lower net rack 4 is connected to the installation cover 15, after the locking installation of the installation cover 15 is completed, the orientation setting of the bottom anti-glare structure including the lower net rack 4 is determined, avoiding the problem of the disadvantage that the integrated guardrail structure cannot be adjusted in direction.

[0041] Combining Embodiment 1 and Embodiment 2, it can not only use the method of adaptively setting the bottom anti-glare structure and the top anti-glare structure according to the traffic flow direction, so that the two-way traffic flows on both sides of the guardrail are not affected by the light, and combine the normal setting of the bottom anti-glare and the addition of a folding anti-glare structure at the top to achieve the comprehensive anti-glare purpose; but also use the detachable split anti-glare structure setting, which can be adaptively adjusted according to the driving direction during installation. The two cooperate to form an effective anti-glare function for the road guardrail, with simple assembly and convenient adjustment.

[0042] The process and principle of the present utility model are as follows:

[0043] Step 1: First, perform the combined clamping installation of the mounting cover 15, and use the longitudinal rod 16 and the transverse rod 17 together to complete the locking and fixing between the mounting cover 15 and the supporting boss 13. Since the lower grid 4 is connected to the mounting cover 15, after completing the locking installation of the mounting cover 15, the orientation of the bottom anti-glare structure including the lower grid 4 is determined, avoiding the problem of the integrated guardrail structure being unable to adjust the direction and having disadvantages in use;

[0044] Step 2: Apply it to the installation on the slope section. Set the entire anti-glare device in the original position of the road guardrail. At this time, set the additional height of the top anti-glare structure according to the traffic flow direction of the road. The specific operation is as follows: First, the folding bottom frame 6 and the folding top frame 7 in the top anti-glare structure are jointly flipped above the bottom anti-glare structure, and the locking rod 21 is used to complete the insertion and locking on both sides. At this time, the top anti-glare structure composed of the folding bottom frame 6 and the folding top frame 7 is vertically overlapped on the upper grid 3 and the lower grid 4, forming an anti-glare range with twice the initial height;

[0045] Step 3: When setting the top anti-glare structure, it is also possible to set whether to add the folding bottom frame 6 and the folding top frame 7. That is, when the folding bottom frame 6 is flipped above the upper grid 3, it is possible to choose not to install the folding top frame 7. And for the initial installation of the guardrail, according to the traffic flow direction, select the orientation of the inclined slot 41 on the lower grid 4 / folding bottom frame 6, so that the inclined slots 41 on the lower grid 4 and the folding bottom frame 6 are arranged away from the traffic flow direction, so that during the vehicle driving forward stage, the state changes from the glare state to the anti-glare state, thereby reducing the glare effect of the oncoming vehicle lights.
