Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of 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.

[0025] Please refer to Figures 1-4, the present utility model provides a technical solution: an emergency traffic signal lamp, which includes a support box 8. A support cylinder 9 is connected to the top of the support box 8. An adjusting device 5 is arranged inside the support cylinder 9. The top of the adjusting device 5 is connected to a signal lamp main body 3. The top of the signal lamp main body 3 is connected to a support box 11. Extension slots 10 are formed on the four sides of the support box 11. An extension device 4 is arranged inside the support box 11. The extension device 4 includes a motor 401, two upper extension plates 403 and two lower extension plates 404. Pin rods 405 are connected to the top of the upper extension plate 403 and the bottom of the lower extension plate 404. The output shaft of the motor 401 is connected to a rotating block 406. Two linkage plates 402 are rotatably connected to the top and bottom of the rotating block 406 respectively. The other end of the linkage plate 402 is rotatably connected to the corresponding pin rod 405. The outer walls of the upper extension plate 403 and the lower extension plate 404 are respectively slidably connected to the inner walls of the extension slots 10, and the bottom of the upper extension plate 403 and the top of the lower extension plate 404 are in contact and slidably connected to each other. The top of the support box 11 is connected to an upper cover 2. The upper cover 2 is connected to an installation box 1. One side of the inner wall of the installation box 1 is fixedly installed with one side of the motor 401, and the output shaft of the motor 401 passes through the upper cover 2 and extends into the support box 11.

[0026] In the specific implementation manner, by setting the extension device 4, the output shaft of the motor 401 drives the rotating block 406 to rotate, and then through the hinged linkage plates 402, the rotating block 406 drives one end of the linkage plate 402 to move. When one end of the linkage plate 402 moves, the other end moves outward, so that the linkage plates 402 drive the upper extension plate 403 and the lower extension plate 404 to move outward respectively, so that the upper extension plate 403 and the lower extension plate 404 form a larger plane for shielding, avoiding the influence on the driver's observation due to attached sundries on the signal lamp in some harsh environments. And by setting the extension slots 10, the movement of the upper extension plate 403 and the lower extension plate 404 is more stable, avoiding deviation and causing jamming to affect the operation.

[0027] The adjusting device 5 includes a sliding rod 502. A connecting block 501 is connected to the top of the sliding rod 502. A moving groove is formed in the sliding rod 502, and a nut is embedded in the moving groove. A threaded rod 503 is in threaded connection with the nut. A rotating block 504 is connected to the bottom of the threaded rod 503. A first bevel gear 507 is connected to one side of the rotating block 504. A second bevel gear 508 is meshed with one side of the first bevel gear 507. A rotating rod 505 is connected to one side of the second bevel gear 508. A turntable 509 is connected to one end of the rotating rod 505. A crank 506 is rotatably connected to one side of the turntable 509. The top of the connecting block 501 is connected to the bottom of the signal lamp main body 3. The inner wall of the support cylinder 9 is in sliding connection with the outer wall of the sliding rod 502. A bearing is embedded at the bottom of the inner wall of the support cylinder 9, and the outer wall of the rotating block 504 is rotatably connected to the inside of the bearing. One end of the rotating block 504 extends into the support box 8. Another bearing is embedded on one side of the support box 8, and the outer wall of the rotating rod 505 is rotatably connected to the inside of the other bearing. A nut is embedded in the inner wall of the support cylinder 9, and a bolt 6 is in threaded connection with the nut. One end of the bolt 6 is in contact with the outer wall of the sliding rod 502. The bottom of the support box 8 is connected with a plurality of moving wheels 7, and all the plurality of moving wheels 7 are self-locking wheels.

[0028] Specific implementation manner: By providing the adjusting device 5, by shaking the crank 506, the crank 506 drives the turntable 509 to rotate, thereby driving the rotating rod 505 to rotate. The rotating rod 505 drives the second bevel gear 508 to rotate. The second bevel gear 508 drives the first bevel gear 507 to rotate. Then, the threaded rod 503 is driven to rotate by the rotating block 504. The sliding rod 502 moves upward through the nut embedded in the sliding rod 502, thereby driving the signal lamp main body 3 to move, so that the device can be adjusted in height as needed, avoiding the influence on viewing due to insufficient height in some special environments, thereby improving the practicability of the device. By providing the bolt 6, after the sliding rod 502 moves to the required position, it is fixed by rotating the bolt 6 to prevent the sliding rod 502 from sliding and affecting the use.

[0029] Working principle: During use, by setting the rotation of the crank 506, the crank 506 drives the turntable 509 to rotate, thereby causing the turntable 509 to drive the rotating rod 505 to rotate. Thus, the second bevel gear 508 drives the first bevel gear 507 to rotate. The first bevel gear 507 drives the threaded rod 503 to rotate, thereby causing the threaded rod 503 to drive the sliding rod 502 to move up and down, so that the signal lamp main body 3 moves up and down to realize the use in different environments. The output shaft of the motor 401 drives the rotating block 406 to rotate, and then the rotating block 406 drives one end of the linkage plate 402 to move, so that the other end of the linkage plate 402 drives the upper extension plate 403 and the lower extension plate 404 to move outwards, thereby forming a shielding plane to prevent sundries from adhering to the signal lamp in bad weather and affecting the driver's observation, thereby improving safety.
