Detailed Description
The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings, in which preferred embodiments in the description are given by way of example only, and all other embodiments obtained by those skilled in the art without making any inventive effort are within the scope of protection of the present utility model.
As shown in fig. 1-4, the specific embodiment adopts the following technical scheme that the novel light-reflecting alarm device comprises a support frame 1 and a folding frame 2, wherein the folding frame 2 is connected between the two support frames 1, a reinforcing rib plate 13 is fixedly arranged on the support frame 1, the reinforcing rib plate 13 can improve the structural strength of the support frame 1, and light-reflecting alarm strips 11 are fixedly adhered to the front side wall and the rear side wall of the support frame 1, so that the warning can be fully provided for people through the light-reflecting characteristic of the light-reflecting alarm strips 11 under the condition of poor illumination;
It also comprises:
The four stress rods 3 are respectively arranged on the front side wall and the rear side wall of the two support frames 1 in a screwed manner through shafts and bearings, clamping grooves 4 are formed in the left stress rod 3, movable grooves 5 are formed in the front side wall and the rear side wall of the right stress rod 3, buffer strips 12 are fixedly bonded on the side walls of the stress rod 3, stress buffering can be provided when other objects collide with the protective railing through the buffering effect of the buffer strips 12, and limiting mechanisms 6 matched with the stress rods 3 are arranged on the front side wall and the rear side wall of the support frames 1;
The two connecting frames 7 are respectively clamped in the two clamping grooves 4, two movable blocks 8 are fixedly arranged on the connecting frames 7 through bolts, the movable blocks 8 are movably arranged in the movable grooves 5, and connecting plates 9 are fixedly arranged on the connecting frames 7 through bolts;
The two threaded rods 10 are respectively arranged on the two connecting plates 9 in a penetrating way through threads, and a plurality of threaded holes matched with the threaded rods 10 are distributed on the side wall of the right stress rod 3 at equal intervals;
