Specific embodiments

[0018] Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution: a windshield;

[0021] This case aims to provide a windshield that is conducive to mobile installation. The existing windshield has a fixed structure, which is not conducive to buffering wind force and is not convenient for mobile installation;

[0022] Based on the above problems, the components in this case include a base 1. The base 1 is integrally concave. A windshield 2 is rotatably connected to the top of the base 1. An extension plate 3 is inserted into the upper side of the windshield. Telescopic rods 4 are installed on both sides of the rear end of the windshield 2. One end of the telescopic rod 4 is connected to a connecting seat 5. A positioning block 6 is provided at the front end of the connecting seat 5. Positioning holes 7 are vertically arranged at the rear end of the extension plate 3. The positioning block 6 penetrates through the windshield 2 and is inserted into the positioning holes 7. Positioning bolts 8 are inserted into both sides of the connecting seat 5 and the positioning block 6. Storage grooves 9 are provided on both sides of the top of the base 1. Support components are respectively connected to both sides of the rear end of the windshield 2 and the inner wall of the storage groove 9;

[0023] The support component includes: a shock absorber 10, a connecting rod 11, an adjusting rod 12, a rotating sleeve 13 and a connecting frame 14;

[0024] One end of the shock absorber 10 is rotatably connected to the inner wall of the storage groove 9. One end of the connecting rod 11 is connected to the other end of the shock absorber 10. One end of the adjusting rod 12 is inserted into the other end of the connecting rod 11. The rotating sleeve 13 is connected to the other end of the adjusting rod 12. The rotating sleeve 13 is rotatably connected to the rear side of the connecting frame 14. The front end of the connecting frame 14 is bolted to the rear end of the windshield 2;

[0025] It should be noted that before installing the windshield 2 screen applied to highway design, the extension plate 3 is retracted inside the windshield 2. At the same time, the windshield 2 will be folded on the top of the base 1. Components such as the shock absorber 10, the connecting rod 11 and the adjusting rod 12 will be placed inside the storage groove 9. The storage groove 9 is integrally T-shaped, which can make the above parts placed inside the storage groove 9. At the same time, the groove 16 provided on the top of the base 1 is deep enough to accommodate the rotating handle 15 and the connecting seat 5 inside the groove 16. At this time, the operator can conveniently move the whole device;

[0026] When the windshield needs to be installed, fix the base 1 on one side of the road, and screw out the windshield 2 from the top of the base 1. Then, adjust the length of the adjusting rod 12 by matching the pin holes with the pins. Then, connect the connecting frame 14 to the rear end of the windshield 2 with bolts. Then, pull out the extension plate 3 from the top of the windshield 2 to adjust the windshield area. Then, press the connecting seat 5 to insert the positioning block 6 into the positioning hole 7. Then, the operator turns the positioning bolt 8 with the rotary handle 15 to thread the positioning bolt 8 with the positioning screw hole, further increasing the fastening between the positioning block 6 and the positioning hole 7, so as to prevent the extension plate 3 from retracting back into the windshield 2. When the windshield 2 is affected by wind force, the shock damping damper 10, the connecting rod 11, the adjusting rod 12, the rotating sleeve 13 and the connecting frame 14 cooperate to buffer the wind force, so as to achieve the function of wind shielding;

[0027] During the construction process, multiple windshields need to be set up. For this purpose, a connecting block 18 and a connecting groove 17 are respectively arranged on both sides of the base 1. By inserting the two and inserting a connecting anchor bolt at the insertion part, it is convenient to connect multiple windshields, so as to increase the wind shielding effect;

[0028] Pin holes are vertically arranged on the outer side of the adjusting rod 12, and a pin is arranged at the connection between the connecting rod 11 and the adjustment. After the length adjustment of the adjusting rod 12 is completed, the position of the adjusting rod 12 can be fixed.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
