Description

Technical Field

[0001] This invention belongs to the technical field of traffic signal light devices, specifically a temporary traffic signal light device. Background Technology

[0002] Traffic lights are signals that direct traffic flow and generally consist of red, green, and yellow lights. A red light indicates that passage is prohibited, a green light indicates that passage is permitted, and a yellow light indicates a warning. Traffic lights are divided into: motor vehicle traffic lights, non-motor vehicle traffic lights, pedestrian crossing traffic lights, directional indicator lights (arrow traffic lights), lane traffic lights, flashing warning traffic lights, and road and railway level crossing traffic lights.

[0003] During some road repairs, the original traffic lights cannot be used. To ensure orderly and safe traffic flow, temporary traffic lights are usually used. However, temporary traffic lights are designed to temporarily direct traffic. Their small size results in a narrow field of vision, making it easy for vehicles in a queue to have their view blocked by vehicles in front. This can lead to vehicles behind in the queue not being able to see the yellow light countdown in time and blindly following the vehicles in front of them to rush through the intersection. This can easily cause collisions with vehicles that are starting quickly from the perpendicular streetlights, threatening the safety of vehicles and people. Therefore, to address the above problems, a temporary traffic light device needs to be designed. Summary of the Invention

[0027] In Embodiment 2, based on Embodiment 1, a threaded shaft 16 is threadedly connected to the bottom of the first lifting square sleeve 4. The threaded shaft 16 is located inside the inverted L-shaped lifting square sleeve 6, and the bottom of the threaded shaft 16 is fixedly connected to the output end of the motor 13. The main lifting component includes first vertical grooves 17 formed on both sides of the first lifting square sleeve 4. First sprockets 18 are rotatably connected to the top and bottom of the two first vertical grooves 17. A first chain 19 is installed between the two first sprockets 18 inside the first vertical groove 17. First fixing blocks 20 are fixedly connected between the two first chains 19 and the upper parts of both sides of the fixed square sleeve 3, and the two first chains 19 are fixedly connected to the lower parts of both sides of the second lifting square sleeve 5. All parts are fixedly connected by a second fixing block 1901; the driven lifting component includes a second vertical groove 21 opened on both sides of the second lifting square sleeve 5, a second sprocket 22 rotatably connected to the top and bottom of the two second vertical grooves 21, a second chain 23 installed between the two second sprockets 22 inside the second vertical groove 21, the second chain 23 is fixedly connected to the upper part inside the first lifting square sleeve 4 by a third fixing block 24, and the two second chains 23 are fixedly connected to the lower part of the surface of the inverted L-shaped lifting square sleeve 6 by a fourth fixing block 25, so that the first lifting square sleeve 4, the second lifting square sleeve 5 and the inverted L-shaped lifting square sleeve 6 can be lifted and adjusted synchronously;

[0028] The motor 13 is started to rotate the threaded shaft 16. The rotation of the threaded shaft 16 causes the first lifting square sleeve 4 to move upward on its surface. The upward movement of the first lifting square sleeve 4 causes the first chain 19 to rotate through the first fixing block 20 and the two first sprockets 18. The rotation of the first chain 19 causes the second lifting square sleeve 5 to move upward through the second fixing block 1901. The upward movement of the second lifting square sleeve 5 causes the second chain 23 to rotate through the third fixing block 24 and the two second sprockets 22. The rotation of the second chain 23 causes the inverted L-shaped lifting square sleeve 6 to move upward through the fourth fixing block 25. Finally, the first lifting square sleeve 4, the second lifting square sleeve 5 and the inverted L-shaped lifting square sleeve 6 rise synchronously to adjust the height.

[0029] In Example 3, based on Example 2, the transmission component includes a third vertical groove 26 formed on one side of the inverted L-shaped lifting square sleeve 6. A first gear 27 is rotatably mounted on the lower part of the third vertical groove 26. A first rack 28 is fixedly mounted on one side inside the second lifting square sleeve 5. The first gear 27 meshes with the first rack 28. A third sprocket 29 is fixedly connected to one side of the first gear 27. A fourth sprocket 30 is rotatably connected to the top of the third vertical groove 26. A third chain 31 is installed between the third sprocket 29 and the fourth sprocket 30. A first bevel gear 34 is fixedly connected to one side of the fourth sprocket 30. The rotational folding transmission component includes a rotational connection... The rotating shaft 32 on the upper part of the third vertical groove 26 has a second bevel gear 33 that meshes with the first bevel gear 34 at its end inside the third vertical groove 26. The upper end of the inverted L-shaped lifting square sleeve 6 has a slot 35. One end of the rotating shaft 32 extends into the slot 35 and is fixedly connected to the third bevel gear 36. Both sides of the slot 35 are rotatably connected to the connecting shaft 37 that is fixedly connected to the upper part of the folding arm 7. One end of the connecting shaft 37 inside the slot 35 is fixedly connected to the fourth bevel gear 38 that meshes with the third bevel gear 36, so that the folding arm 7 can be effectively rotated and unfolded.

[0030] When the inverted L-shaped lifting square sleeve 6 moves upward, it drives the first gear 27 to roll and rotate on the surface of the first rack 28. The rotation of the first gear 27 drives the third sprocket 29 to rotate. The rotation of the third sprocket 29 drives the first bevel gear 34 to rotate through the third chain 31 and the fourth sprocket 30. The rotation of the first bevel gear 34 drives the second bevel gear 33 to rotate, which in turn drives the rotating shaft 32 to rotate. The rotation of the rotating shaft 32 drives the third bevel gear 36 to rotate, which in turn drives the fourth bevel gear 38 to rotate. The rotation of the fourth bevel gear 38 causes the connecting shaft 37 to drive the folding arm 7 to rotate. The upward movement of the inverted L-shaped lifting square sleeve 6 also drives the folding arm 7 to move upward. At the same time, the folding arm 7 also rotates during the upward movement, eventually causing the folding arm 7 to rotate 90° and become horizontal.

[0031] In Example 4, based on Example 3, the telescopic transmission component includes a large-pitch threaded rod 39 rotatably connected to the middle of the folding arm 7. One end of the folding arm 7 has a square hollow groove structure. The telescopic arm 8 is movably inserted into the inside of the square hollow groove and threadedly connected to the large-pitch threaded rod 39. One end of the large-pitch threaded rod 39 extends into the inside of the slot 35 and is fixedly connected to a second gear 40. An arc-shaped rack 41 that meshes with the second gear 40 is fixedly connected to one side inside the slot 35, thereby enabling effective adjustment of the extension and unfolding of the telescopic arm 8.

[0032] When the folding arm 7 rotates, it drives the second gear 40 to rotate. The rotation of the second gear 40 causes the second gear 40 to roll on the surface of the arc rack 41. The rotation of the arc rack 41 drives the large-pitch threaded rod 39 to rotate. The rotation of the large-pitch threaded rod 39 causes the telescopic arm 8 to move rapidly on its surface and move out of the folding arm 7 to unfold. Finally, the telescopic arm 8 will rotate 90° with the folding arm 7 and become horizontal.

[0033] The moving part includes two slide rods 42 fixedly connected to one side of the folding arm 7, a moving block 43 slidably sleeved between the two slide rods 42, a moving block 43 fixedly connected to one end of one side of the moving plate 9, and a mounting block 44 fixedly connected between the other end of one side of the moving plate 9 and one end of the telescopic arm 8, so that the moving plate 9 can move effectively.

[0034] When the telescopic arm 8 is moved out of the folding arm 7 and unfolded, the movement of the telescopic arm 8 will drive the moving plate 9 to move through the mounting block 44. The movement of the moving plate 9 will drive the moving block 43 to move on the surface of the two slide bars 42. Finally, the moving plate 9, the mounting plate 10 and the four indicator lights 12 will rotate 90° with the telescopic arm 8 and the folding arm 7 and be in a horizontal position.

[0035] In Example 5, based on Example 4, the lifting transmission component includes a second rack 45 fixedly installed on one side of the folding arm 7, an n-shaped block 46 fixedly installed between one end of the moving block 43, a third gear 47 rotatably connected to the inner side of the n-shaped block 46 and meshing with the second rack 45, a fifth bevel gear 48 fixedly connected to one side of the third gear 47, a rotating pin 49 rotatably connected to the middle of the n-shaped block 46, a sixth bevel gear 50 fixedly connected to the inner end of the rotating pin 49 and meshing with the fifth bevel gear 48, and a seventh bevel gear 51 fixedly connected to the other end of the rotating pin 47; the lifting adjustment component includes four centrally symmetrical sliding grooves 52 formed on one side of the moving plate 9. The inner cavity groove 53 is opened in the middle of the movable plate 9. The interior of the four sliding grooves 52 is rotatably connected to the rotating screws 54. One end of each of the four rotating screws 54 extends into the interior of the inner cavity groove 53 and is fixedly connected to the eighth bevel gear 55. The four eighth bevel gears 55 are meshed with each other. The other end of one of the rotating screws 54 extends to the outside of one end of the movable plate 9 and is fixedly connected to the ninth bevel gear 56. The ninth bevel gear 56 is meshed with the seventh bevel gear 51. The surface of each rotating screw 54 is threaded with a movable slider 57. The four lifting rods 11 are rotatably connected between the ends of the four movable sliders 57 and the other side of the mounting plate 10, so as to effectively lift and adjust the mounting plate 10.

[0036] When the moving block 43 moves on the surface of the two sliding rods 42, it drives the n-shaped block 46 to move. The movement of the n-shaped block 46 drives the third gear 47 to roll and rotate on the surface of the second rack 45. The rotation of the third gear 47 drives the sixth bevel gear 50 to rotate through the fifth bevel gear 48. The rotation of the sixth bevel gear 50 drives the seventh bevel gear 51 to rotate through the rotating pin 49. The rotation of the seventh bevel gear 51 drives the ninth bevel gear 56 to rotate one of the rotating screws 54. The rotation of one of the rotating screws 54 drives the other three rotating screws 54 to rotate synchronously through the four eighth bevel gears 55. The rotation of the four rotating screws 54 causes the four moving sliders 57 to move relative to each other. The four relatively moving moving sliders 57 press against the four lifting rods 11, thereby pushing the mounting plate 10. Finally, the mounting plate 10 drives the four signal lights 12 to rise, making it easier for people to observe.

[0037] This temporary traffic signal device has lifting and extension / folding adjustment functions, and the lifting and extension / folding adjustments can be carried out synchronously, thereby increasing the visibility height and range of the traffic signal, which is conducive to improving the efficiency of traffic control and the safety of traffic at intersections. In addition, this temporary traffic signal device has a simple structural design, is convenient to use and operate, and is stable and reliable in adjustment. Its performance can meet the needs of temporary traffic control.
