[0008] Preferably, the front surface of the box door is longitudinally provided with limiting slide grooves near both sides, the front surface of the box door is fixedly installed with side baffles on both sides of the upper end of the limiting slide grooves, and gears are movably installed between the side baffles.

[0009] Preferably, a support plate is fixedly installed on the bottom of the flashing warning light, a No. 2 rack is fixedly installed on the upper surface of the support plate and located behind both sides, and a limiting slide is fixedly installed on the rear surface of the No. 2 rack.

[0010] Preferably, the limiting slide is embedded in the limiting slide groove, the flashing warning light is movably connected to the box door through the limiting slide, and the No. 2 rack is engaged with the gear.

[0011] Preferably, the lower end of the No. 1 rack extends between the side baffles on both sides of the limiting slide groove, and the No. 1 rack is also engaged with the gear.

[0012] Preferably, the front end of the side baffle is fixed to the telescopic pull rod, and the bottom of the support plate is in contact with the supporting plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the utility model, a telescopic pull rod, a box door and a strobe warning light are arranged to cooperate with each other. When the staff uses the telescopic pull rod to move the sound and light alarm to the designated position on the highway, the telescopic end of the telescopic pull rod is pressed downward. At this time, the No. 1 rack descends, and the continuously descending No. 1 rack drives the gear of the box door to rotate. The rotating gear drives the No. 2 rack of the strobe warning light to move upward. When the telescopic end of the telescopic pull rod is fully retracted, the strobe warning light rises to the highest position, so that the strobe warning light can be used normally. If the staff needs to move the sound and light alarm again, the telescopic end of the telescopic pull rod is pulled out, and the strobe warning light will be lowered and placed. This can prevent the strobe warning light from being damaged during the movement. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The rear surface of both sides of the telescopic end of the telescopic pull rod 5 and the upper part thereof are fixedly installed with a No. 1 rack 501, the rear surface of the No. 1 rack 501 and the upper part thereof are fixedly installed with a connecting block 502, the rear surface of the lower end of the telescopic pull rod 5 is fixedly installed with a supporting plate 503, the telescopic pull rod 5 is movably connected to the box door 8 through the supporting plate 503, the No. 1 rack 501 is fixed to the telescopic end of the telescopic pull rod 5 through the connecting block 502, and the No. 1 rack 501 can drive the gear 803 to rotate when it is lifted up and down; the front surface of the box door 8 and the two sides thereof are longitudinally provided with a limiting slide groove 801, the front surface of the box door 8 and the upper ends of the limiting slide groove 801 are fixedly installed with side baffles 802, and a gear 803 is movably installed between the side baffles 802, and the rotating gear 803 can prompt the No. 2 rack 902 Lifting; a support plate 901 is fixedly installed at the bottom of the flashing warning light 9, and a second rack 902 is fixedly installed on the upper surface of the support plate 901 and located at the rear of both sides. A limiting slide 903 is fixedly installed on the rear surface of the second rack 902. The cooperation of the limiting slide 903 and the limiting slide groove 801 can assist the vertical lifting of the flashing warning light 9; the limiting slide 903 is embedded in the limiting slide groove 801, and the flashing warning light 9 is movably connected to the box door 8 through the limiting slide 903, and the second rack 902 is engaged with the gear 803; the lower end of the No. 1 rack 501 extends between the side baffles 802 on both sides of the limiting slide groove 801, and the No. 1 rack 501 is also engaged with the gear 803; the front end of the side baffle 802 is fixed to the telescopic pull rod 5, and the bottom of the support plate 901 is in contact with the support plate 503.

[0023] It should be noted that the present invention is a sound and light alarm for highways. When in use, after the staff uses the telescopic pull rod 5 to move the sound and light alarm to the designated position on the highway, the telescopic end of the telescopic pull rod 5 is pressed downward. At this time, the No. 1 rack 501 drops, and the continuously dropping No. 1 rack 501 drives the gear 803 of the box door 8 to rotate, and the rotating gear 803 drives the No. 2 rack 902 of the flashing warning light 9 to move upward. When the telescopic end of the telescopic pull rod 5 is fully retracted, the flashing warning light 9 rises to the highest position, so that the flashing warning light 9 can be used normally. If the staff needs to move the sound and light alarm again, the telescopic end of the telescopic pull rod 5 is pulled out, and the flashing warning light 9 will be lowered and placed. This can prevent the flashing warning light 9 from being damaged due to extending above the chassis 1 during the movement.
