In order to achieve the above purpose, the utility model adopts the following technical scheme:

a novel highway anti-collision barrel comprises a barrel cover, a barrel body, a buffer block and a rotary fixing shaft; the barrel cover is buckled above the barrel body; a plurality of limiting holes are formed in the outer ring of the barrel body; the rotary fixing shafts penetrate through the limiting holes one by one and are fixed on the barrel body through fastening nuts; the buffer block is cylindrical and provided with a through rotating connecting hole, and is rotationally connected with the rotating fixed shaft through the rotating connecting hole;

the diameter of the rotating fixing shaft is smaller than that of the rotating connecting hole on the buffer block, so that the buffer block can freely rotate around the rotating fixing shaft;

the rotating fixing shaft is provided with a plurality of buffer blocks, each buffer block is not radially constrained on the rotating fixing shaft, and each buffer block can freely move up and down.

Furthermore, the locking mode of the fastening nut can be a double-nut locking mode, a spring gasket adding mode or a self-locking nut directly used.

Furthermore, the buffer block is made of polyurethane materials and is arranged in a honeycomb shape.

Furthermore, a warning reflective film is pasted on the outer circumference of the buffer block.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. the anti-collision barrel in the utility model is filled with sand or water, thereby increasing the self weight; through the rotatory fixed axle and the buffer block that set up, when the vehicle was because of unexpected striking anti-collision barrel, the vehicle at first can contact with the buffer block on the rotatory fixed axle for the buffer block takes place to rotate, thereby reaches the effect of unloading power.

2. The utility model discloses in through the cellular buffer block that sets up, the vehicle striking in-process plays certain buffering energy-absorbing effect, further improves the anticollision effect of anticollision bucket.

3. The utility model discloses in through the fastening nut, the rotatory fixed axle that set up, when the vehicle striking dynamics is great, at first can damage rotatory fixed axle and buffer block, if the staving is not damaged, only need to change buffer fixed axle and buffer block can, during installation buffer block and rotatory fixed axle, only need with the buffer block cluster on rotatory fixed axle, through fastening nut fixed rotatory fixed axle can, effectively realize cyclic utilization and install fast.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, a novel highway anti-collision barrel comprises a barrel cover 5, a barrel body 6, a buffer block 1 and a rotary fixing shaft 2. The barrel cover 5 is buckled above the barrel body 6; the outer ring of the barrel body 6 is provided with a plurality of limiting holes 7, the rotating fixed shaft 2 passes through the limiting holes 7 and is fixed on the barrel body 6 through the fastening nuts 3, preferably, the fastening nuts 3 can be locked in a double-nut locking mode, a spring gasket adding mode or self-locking nuts and the like are directly used, so in the embodiment, the fastening nuts 3 are locked in a double-nut locking mode, the rotating fixed shaft 2 is fixed on the barrel body through the fastening nuts 4 arranged above the fastening nuts 3, the fastening nuts 3 are rotated clockwise to be screwed, and the fastening nuts 4 are rotated anticlockwise to be screwed.
