Description

Technical Field

[0001] The utility model relates to the technical field of highway traffic safety, and specifically discloses a novel highway traffic safety protection device. Background Art

[0002] On expressways or roads, many traffic accidents occur every year where vehicles collide with guardrails, causing personal injuries, vehicle and guardrail repairs, and economic losses.

[0003] The existing guardrails are made of iron and are inelastic. This rigid guardrail has strong protective capabilities, but when it collides with a car, it cannot absorb the collision kinetic energy, cannot buffer and release the impact force, and cannot offset the impact force. The safety protection effect is poor, which often causes the disintegration of large vehicles and loss of control, or serious injuries or even death. Therefore, a new type of highway traffic safety protection device is needed to solve this problem. Utility Model Content

[0006] In order to facilitate the provision of buffer force by the first buffer spring, the second buffer spring and the third buffer spring, as a preferred new type of highway traffic safety protection device of the utility model, the upper end of the first buffer spring is fixedly connected to the fixed frame, the lower end of the first buffer spring is fixedly connected to the first sleeve, the upper end of the second buffer spring is fixedly connected to the second sleeve, the lower end of the second buffer spring is fixedly connected to the fixed frame, the upper end of the third buffer spring is fixedly connected to the first sleeve, and the lower end of the third buffer spring is fixedly connected to the second sleeve.

[0007] In order to reduce impact damage, as a preferred novel highway traffic safety protection device of the utility model, a sponge pad is provided on the outer wall of the anti-collision plate.

[0012] The novel highway traffic safety protection device cooperates with a connecting shaft, a first sleeve, a second sleeve, a connecting rod, a first buffer spring, a second buffer spring and a third buffer spring. When impacted, the anti-collision plate drives the first sleeve and the second sleeve to slide opposite to each other along the connecting shaft through the connecting rod, thereby compressing the first buffer spring and the second buffer spring and stretching the third buffer spring. The first buffer spring, the second buffer spring and the third buffer spring are used for buffering to reduce the damage to the vehicle. When impacted, the anti-collision plate rotates along the connecting shaft through the connecting rod, the first sleeve and the second sleeve to further relieve the impact force, reduce the damage to the vehicle and the anti-collision plate, and have a good protection effect.
