Detailed Description

The following provides a detailed description of the present invention with reference to the accompanying drawings, which is provided to further explain the constitution of the present invention in detail.

The automatic flag-shaking device for avoiding vehicles for road maintenance comprises a base 1, wherein an adjusting pad 2 is arranged on the upper portion of the base 1, a speed reducer 7 is fixedly connected to the upper portion of the adjusting pad 2 through a bolt 5, a motor 6 is connected to the right end of the speed reducer 7, the left end of the speed reducer 7 is connected with a transmission shaft 13 through an elastic coupling 8, a gland 14 is fixedly connected to the periphery of the middle portion of the transmission shaft 13 through a first screw 15, a bearing 9 is arranged in the gland 14, a rocker 27 is fixedly connected to the left end of the transmission shaft 13, a first round nut 12 is arranged on one side of the rocker 27, the lower end of the rocker 27 is connected with a swing rod 26 through a pin shaft 16, a slider 20 is arranged at the left end of the pin shaft 16, a second round nut 31 is arranged on one side of the slider 20, the lower end of the swing rod 26 is connected, a red flag 29 is arranged on the adjustable flagpole 30, and a set screw 28 is arranged at the top of the swing rod 26; an elastic washer 3 and a flat washer 4 are sequentially and tightly connected between the adjusting pad 2 and the bolt 5; a first washer 10 and a backstop washer 11 are sequentially and fixedly connected between the first round nut 12 and the rocker arm 27; the pin shaft 16 is fixedly connected with the rocker arm 27 through a conical end set screw 17 and a flat end set screw 18; the periphery of the pin shaft 16 is sleeved with a spacer bush 21; in order to prevent the slide block 20 and the swing rod 26 from axially moving, a second washer 19 is tightly connected between the second round nut 31 and the slide block 20; in order to prevent the swing link 26 from moving axially, a third washer 22 is tightly connected between the second screw 23 and the hinge seat 24.

The adjusting pad 2 is used for centering adjustment of the speed reducer 7 and the transmission shaft 13, and after centering, the adjusting pad is fastened on the base 1 by using the bolt 5, the elastic washer 3 and the flat washer 4;

the slider 20 can rotate on the pin 16 and can slide in the sliding groove of the swing rod 26.

The working principle is as follows: when a motor start button is pressed down, power is transmitted to the transmission shaft 13 from the motor 6 arranged on the base 1 through the speed reducer 7 in a speed reduction mode, the rocker arm 27 is fixed on the transmission shaft 13 through key connection, and the transmission shaft 13 drives the rocker arm 27 to do circular motion around the transmission shaft 13 through rotating on the two support bearings 9. When the rocker arm 27 rotates from the right side to the left side of the lower end, that is, the rocker arm 27 rotates clockwise by a certain angle, the slider 20 connected to the rocker arm 27 also rotates clockwise by the same angle, and simultaneously drives the swing rod 26 to swing back to the left side from the right side; the flag pole 30 drives the red flag 29 to complete a go-round along with the swing rod 26, when the swing arm 27 rotates from the left end to the right end of the upper part, that is, the swing arm 27 rotates clockwise by a certain angle, the slider 20 connected to the swing arm 27 also rotates clockwise by the same angle, and simultaneously drives the swing rod 26 to swing from the left to the right, the flag pole 30 drives the red flag 29 to complete a go-round along with the swing rod 26, and at this time, the swing arm 27 just rotates for a circle. That is, when the swing arm 27 rotates for one circle, the slider 20 connected to the swing arm 27 also rotates for one circle, and simultaneously drives the swing rod 26 to swing back and forth once; the flag pole 30 is installed on the swing rod 26, and the flag pole 30 drives the red flag 29 to swing back and forth along with the swing rod 26. When the swing arm 27 continues to rotate, the flag pole 30 drives the red flag 29 to continue to swing left and right, so that the red flag 29 automatically swings. The length of the flag pole 30 is adjusted by tightening the screw 28.

The details of the present invention not described in detail are the prior art, and those skilled in the art can derive the present embodiment and the prior art and modify the present embodiment to obtain other embodiments. Therefore, the scope of the present invention should be determined based on the claims.
