DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-4A road curve crash barrier shown in the figure includes a support base 1, which is fixed at the curve of the road. A support side plate 2 is installed on one side wall of the support base 1, and support rods 3 are respectively slidably clamped on the support side plates 2. The number of support rods 3 is four, which are evenly distributed on the support side plates 2. A fixed base 5 is installed at one end of the support rod 3, and a buffer assembly 6 is installed on the fixed base 5. A buffer spring 4 is arranged on the side wall of the support rod 3. When the crash barrier is hit by a vehicle, the vehicle first contacts the buffer assembly 6, and the fixed base 5 is driven to move by the buffer assembly 6, so that the buffer spring 4 can be compressed to absorb the impact force. A supporting cross plate 8 is fixedly installed on one side wall of the fixed base 5, and limiting blocks 9 are respectively installed on the top outer walls of the supporting cross plate 8. A clamping side plate 12 is installed on one side wall of the support side plate 2, and support shafts 13 are respectively slidably clamped on the clamping side plates 12. The support shafts 13 When the vehicle is in a state of being moved backwards, the stopper 14 is moved back and forth, and ...

[0022] In this embodiment, a fixed side plate 15 and a fixed side plate 2 16 are respectively installed on one side wall of the supporting side plate 2, a buffer plate 18 is rotatably connected to the fixed side plate 15, a support block 17 is rotatably connected to the fixed side plate 2 16, a guide column 21 is installed on one side wall of the support block 17, a support block 2 19 is rotatably connected to the buffer plate 18, a guide sleeve 20 is installed on one side wall of the support block 2 19, the guide sleeve 20 is slidably engaged with the guide column 21, and a buffer spring 22 is arranged on the side wall of the guide column 21. When the fixed base 5 drives the buffer spring 1 4 to be compressed to a certain extent, the fixed base 5 will contact the buffer plate 18, thereby driving the buffer plate 18 to rotate, so that the buffer plate 18 can drive the guide sleeve 20 to slide on the guide column 21, thereby driving the buffer spring 22 to be compressed, and the impact force can be further absorbed by the buffer spring 22.

[0023] In this embodiment, guide blocks 23 are respectively installed on the side walls of the guide column 21 , and the guide blocks 23 are slidably engaged with the guide sleeve 20 . The guide blocks 23 can limit the guide sleeve 20 to prevent the guide sleeve 20 from falling off the guide column 21 .

[0024] In this embodiment, the buffer assembly 6 includes a buffer base plate 601, which is clamped with the fixed base 5. An energy absorption box 602 is installed on one side wall of the buffer base plate 601, a protective panel 603 is installed on one side wall of the energy absorption box 602, and fixing bolts 7 are installed on the fixed base 5. The fixed base 5 is connected to the buffer base plate 601 through the fixing bolts 7. When the vehicle hits the buffer assembly 6, it first contacts the buffer base plate 601. When the buffer spring 1 4 and the buffer spring 2 22 are compressed into place, the energy absorption box 602 will collapse, thereby further absorbing the impact force, which is beneficial to improving the anti-collision effect of the crash barrier.

[0025] Working principle of the utility model: The utility model is a road bend crash barrier. When the crash barrier is hit by a vehicle, the vehicle first contacts the buffer component 6, so that the buffer component 6 can drive the fixed base 5 to move, so that the buffer spring 4 can be compressed to absorb the impact force;

[0026] When the fixed base 5 moves, it will drive the supporting cross plate 8 to move backward. During the process of the supporting cross plate 8 moving backward, the limit block 9 will drive the T-shaped limit plate 11 to rise. Whenever the T-shaped limit plate 11 passes through a limit block 9, the support spring 14 will drive the T-shaped limit plate 11 to descend, so that it can limit the limit block 9, thereby limiting the fixed base 5, and avoiding the buffer spring 4 from rebounding immediately after being compressed, thereby preventing the buffer spring 4 from rebounding and causing a secondary impact on the car. After the accident is handled, by pulling the T-shaped limit plate 11, it will no longer limit the limit block 9, so that the buffer spring 4 can drive the fixed base 5 to rebound to its original position.

[0027] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
