Detailed Description
In fig. 1, the invention is pre-buried in paved roads, and the rear baffle frame 4 is positioned on the same plane with the roads after being laid flat. The invention is composed of 6 parts of a front baffle frame 1, a support bearing 2, a rotating shaft 3, a rear baffle frame 4, a bayonet 5 and a triangular thorn cone 6. The front baffle frame 1 is connected with the rotating shaft 3 through a bearing, can radially rotate and can not move axially. The rear baffle frame 4 is connected with the rotating shaft 3 through a bearing, can radially rotate and can not move axially. The rotating shaft 3 is connected with the support bearing 2, can radially rotate and can not move axially. The front baffle frame 1 and the rear baffle frame 4 are overlapped on the rotating shaft 3, the bayonet lock 5 is arranged on a shaft sleeve connected with the front baffle frame 1 and the rotating shaft 3, and an included angle between the front baffle frame 1 and the rear baffle frame 4 is 120 degrees. The tailgate frame 4 freely falls on the bayonet 5, rises with the rotation of the front tailgate frame 1, and rotates along the rotation shaft 3. The triangular thorn cone 6 is connected with the rear baffle frame 4 and is locked by a stop block, and the angle is adjustable. The back baffle frame 4 is slightly heavier than the front baffle frame 1, when the back baffle frame 4 is parallel to the horizontal plane, the gravity center point is on the back baffle frame 4, the front baffle frame 1 is tilted under the action of the bayonet lock 5, the front baffle frame 1 is turned anticlockwise along with the work of the whole device, the whole gravity center moves along with the turning process, and finally the gravity center moves to the front baffle frame 1 through the rotating shaft 3, and the back baffle frame 4 is tilted under the action of the bayonet lock 5.
