DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 3 The utility model provides a technical solution: a corrugated beam guardrail, comprising a cylindrical welding part 2, an arc-shaped connecting piece 4, a sliding rod 9 and a metal cylinder 11. The arc-shaped connecting piece 4 is attached to the left side of the corrugated beam guardrail 3. The upper and lower sides of the right end of the cylindrical welding part 2 are horizontally installed with a metal cylinder 11 through a plurality of bolts. The front ends of the two metal cylinders 11 are penetrated with an elliptical slide groove 12. Two sliding rods 9 are provided. The right ends of the two sliding rods 9 are both installed with a connecting head 8. The two connecting heads 8 are symmetrically installed with arc-shaped rubber blocks 7. The two sliding rods 9 are respectively slidably inserted into the two metal cylinders 11. The left sides of the front ends of the two sliding rods 9 are penetrated and fixed with a metal pin 10. The right ends of the two metal cylinders 11 are welded with a fixed sleeve 15. The left ends of the two fixed sleeves 15 are both installed with a spring 14. The left ends of the two springs 14 are connected with a movable sleeve 13. This design solves the problem that the corrugated beam guardrail in the original device has limited energy absorption and will rupture once excessive absorption occurs.

[0020] As the first embodiment of the utility model: the cylindrical welding part 2 is welded to the right end of the column 1. The added cylindrical welding part 2 facilitates the horizontal installation of the two metal cylinders 11. A plurality of second oval head rivets 6 are fixed through the arc-shaped connecting piece 4 and the corrugated beam guardrail 3. The added plurality of second oval head rivets 6 enable the arc-shaped connecting piece 4 and the corrugated beam guardrail 3 to be installed and fixed. A first oval head rivet 5 is provided through the cylindrical welding part 2, the arc-shaped connecting piece 4 and the corrugated beam guardrail 3. The added first oval head rivet 5 facilitates the installation and fixation between the cylindrical welding part 2, the arc-shaped connecting piece 4 and the corrugated beam guardrail 3.

[0021] The arc surfaces of the two arc-shaped rubber blocks 7 are both in contact with the arc-shaped connecting piece 4. The two added arc-shaped rubber blocks 7 can assist the arc-shaped connecting piece 4 and the corrugated beam guardrail 3, and then when the corrugated beam guardrail 3 absorbs the impact force of the car, the force transmitted by it is dispersed. Two metal pins 10 are respectively inserted and slidably arranged in the two elliptical slide grooves 12, and two movable sleeves 13 are respectively slidably sleeved on the annular side surfaces of the two metal cylinders 11, and the two movable sleeves 13 are respectively welded to the two metal pins 10. Through the two added metal pins 10, when the arc-shaped rubber block 7 and the connecting head 8 drive the slide bar 9 to move to the left, the movable sleeve 13 is driven to move with it, so that the spring 14 can be stretched, so that the spring 14 absorbs the force transmitted by it.

[0022] As the second embodiment of the utility model: in actual use, the corrugated beam guardrail 3 absorbs the impact force of the car, and at the same time transmits it to the two arc-shaped rubber blocks 7 and the two connecting heads 8 through the arc-shaped connecting piece 4, so that the two connecting heads 8 can drive the two sliding rods 9 to slide to the left in the two metal tubes 11, and then drive the two metal pins 10 to move to the left in the two elliptical slide grooves 12, thereby pulling the two movable sleeves 13 to move to the left outside the two metal tubes 11. In this process, the two springs 14 can be stretched, so that the two springs 14 can absorb and disperse the force transmitted by them.

[0023] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
