Detailed Description
For a better understanding of the present invention, embodiments thereof are explained in detail below with reference to the accompanying drawings.
As shown in the attached drawings 1 to 3, the height-limiting warning road signboard comprises a signboard body 1, wherein a height-limiting warning board 2, an electronic screen 3 and a servo motor 4 are arranged on the back surface of the signboard body 1. The rear end of limit for height warning sign 2 is connected with the body of rod 21, the latter half of the body of rod 21 is provided with rack 22, and the body of rod 21 transversely sets up the intermediate position at the tablet body 1 the back the place ahead of tablet body 1 is provided with the confession the sliding sleeve 11 that the body of rod 21 passed, sliding sleeve 11 are annular through-hole, and the body of rod 21 can slide in sliding sleeve 11. A bracket 12 for supporting the rear end of the rod body 21 is arranged behind the back of the card body 1, the cross section of the bracket 12 is a C-shaped groove, and the rod body 21 can slide in the bracket 12.
The servo motor 4 is connected with a gear 5 matched with the rack 22 in a driving way. The gear 5 is located above the rod 21 and engages with the rack 22 on the rod 21. The servo motor 4 is fixed on the back of the card body 1 through a fixing frame, and an output shaft of the servo motor can be directly in driving connection with the gear 5 or can be connected through a gear set or a transmission belt.
