SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that not enough among the above-mentioned prior art is directed against, provide a developments elasticity rotatory belt guardrail, can be when the vehicle strikes the guardrail, effectually let out the striking strength to realize the flexonics, avoid causing huge damage to the vehicle.
In order to solve the technical problem, the utility model discloses a technical scheme is: a dynamic elastic rotary belt guardrail comprises two roller units which are oppositely arranged and a belt which is erected on the two roller units; the two roller units are arranged on the inner sides of the two ends of the belt in a penetrating manner to tighten the belt; the belt can rotate along with the rotation of the roller unit; two the roller unit is vertical cartridge at the road edge, and constitutes road guardrail with the belt.
The dynamic elastic rotating belt guardrail comprises a vertical rod fixedly inserted on the ground and a roller coaxially sleeved on the vertical rod, wherein the positions of the vertical rod, which are close to the upper end and the lower end, are respectively sleeved with a bearing, and the outer rings of the two bearings are abutted against the inner wall of the roller; the belt is arranged on the roller in a lapping mode.
Above-mentioned developments have rotatory belt guardrail of elasticity, the roller have a plurality of protruding stupefied on the surface, every protruding stupefied all lays along the axial of roller, and is a plurality of protruding stupefied evenly lays along the circumferencial direction of roller, the inboard of belt is seted up many recesses that supply protruding stupefied embedding on the surface.
Above-mentioned developments have rotatory belt guardrail of elasticity, the width of belt is greater than the length of protruding stupefied.
The dynamic elastic rotary belt guard, the belt and the roller can be made of elastic materials.
Above-mentioned rotatory belt guardrail of developments elasticity, the pole setting is close to position department cover of lower extreme and is equipped with a saucer, the upper end demountable installation of pole setting has the end cover, saucer and end cover carry out the belt about spacing.
Compared with the prior art, the utility model has the following advantage: the utility model discloses an utilize the belt rotation to let out the strength of vehicle striking, can prevent effectively that huge rigidity from taking place to the vehicle and strikeing, can effectively protect car and navigating mate.
The technical solution of the present invention is further described in detail by the accompanying drawings and examples.

Detailed Description
As shown in fig. 1, 2 and 3, a dynamic elastic rotating belt 2 guard rail comprises two roller units 1 which are oppositely arranged and a belt 2 which is arranged on the two roller units 1; the two roller units 1 penetrate through the inner sides of the two ends of the belt 2 to tighten the belt 2; the belt 2 can rotate along with the rotation of the roller unit 1; two roller units 1 are vertically inserted at the edge of a road and form a road guardrail with a belt 2.
During the in-service use, when the vehicle from oblique rear striking to belt 2 on, can drive belt 2 rotatory to let out the impact strength, and utilize the flexibility of belt 2, can reduce the rigidity impact to the car, thereby protected car and navigating mate.
The roller unit 1 comprises a vertical rod 3 which is inserted and fixed on the ground and a roller 4 which is coaxially sleeved on the vertical rod 3, bearings 5 are respectively sleeved at the positions, close to the upper end and the lower end, of the vertical rod 3, and the outer rings of the two bearings 5 are abutted to the inner wall of the roller 4; the belt 2 is set up on the roller 4.
By arranging the bearing 5, the roller 4 can be effectively helped to rotate, so that the belt 2 can rotate in time when being impacted.
The surface of the roller 4 is provided with a plurality of convex ridges 6, each convex ridge 6 is arranged along the axial direction of the roller 4, the convex ridges 6 are uniformly arranged along the circumferential direction of the roller 4, and the inner side surface of the belt 2 is provided with a plurality of grooves 7 for embedding the convex ridges 6.
Through setting up protruding stupefied 6 and recess 7, can let meshing between belt 2 and the roller 4, prevent that sliding friction from appearing.
The width of the belt 2 is larger than the length of the convex edge 6. The width of the belt 2 is made to be larger than the length of the convex edge 6, so that the belt 2 can be hung on the convex edge 6 by the convex edge 6 embedded into the groove 7, and the trend that part of the belt 2 moves downwards is offset.
Both the belt 2 and the roller 4 may be made of an elastic material. The elastic material is rubber. The roller 4 is also made of an elastic material in order to absorb the impact and restore the original shape when the roller 4 is hit.
The position department cover that pole setting 3 is close to the lower extreme is equipped with a saucer 8, the upper end demountable installation of pole setting 3 has end cover 9, saucer 8 and end cover 9 are spacing about carrying on belt 2. The end cover 9 is screwed on the end surface of the top end of the upright rod 3 through a bolt in the middle.
The utility model discloses during the use, lay a set ofly in bank along road extending direction at the edge of road 2 guardrails of dynamic elasticity rotatory belt, when the vehicle meets accident and will dash out the road, the guardrail can carry out the flexibility to the vehicle and block.
The above, only be the utility model discloses a preferred embodiment, it is not right the utility model discloses do any restriction, all according to the utility model discloses the technical entity all still belongs to any simple modification, change and the equivalent structure change of doing above embodiment the utility model discloses technical scheme's within the scope of protection.
