DETAILED DESCRIPTION

[0024] 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.

[0025] See also Figure 1-7 The utility model provides a novel high-speed guardrail connector, including a connecting component 2 for connecting a column 1 and a beam 3.

[0026] The connecting assembly 2 includes: a mounting block 21, a positioning member 22 and a connecting member 24. The outside of the mounting block 21 is fixedly connected to the side of the connecting column 1. Positioning members 22 for positioning the connecting member 24 are provided on both sides of the mounting block 21. The inside of the mounting block 21 is provided with a connecting member 24 for connecting the crossbeam 3 and a buffer protection member 23 for buffering protection. The buffer protection member 23 is located on one side of the connecting member 24.

[0027] The outside of the mounting block 21 is fixedly connected to the side of the column 1 , a receiving groove 211 is formed on the top of the mounting block 21 , and a U-shaped groove 214 is formed on the groove wall of the receiving groove 211 .

[0028] The connecting member 24 includes: a limiting plate 241 and a connecting column 243. The outer portion of the limiting plate 241 is slidably connected to the groove wall of the accommodating groove 211. One side of the limiting plate 241 is fixedly connected to one end of the connecting column 243. The other end of the connecting column 243 is fixedly connected to the outer portion of the crossbeam 3. The outer portion of the connecting column 243 is slidably connected to the groove wall of the U-shaped groove 214.

[0029] The end of the connecting column 243 is fixedly connected to the outside of the beam 3, so that the connecting piece 24 and the beam 3 form a whole. The bottom of the limiting plate 241 is provided with an arc surface 242 that is convenient for inserting into the receiving groove 211. The limiting plate 241 is inserted into the receiving groove 211, and the receiving groove 211 limits the limiting plate 241, thereby achieving the limitation of the beam 3.

[0030] A square cavity 213 is provided inside the mounting block 21 . There are two groups of square cavities 213 symmetrically arranged on both sides of the U-shaped groove 214 . Circular through holes 212 are provided on both sides of the mounting block 21 . The circular through holes 212 are connected to the square cavities 213 .

[0031] The positioning member 22 includes: a limit block 222, a pull rod 225 and a limit seat 224. The outside of the limit block 222 is slidably inserted into the cavity wall of the square cavity 213. One side of the limit block 222 is provided with a slope 221. The other side of the limit block 222 is fixedly connected to one end of the pull rod 225, and the other end of the pull rod 225 is fixedly connected to one side of the limit seat 224.

[0032] The outside of the pull rod 225 is slidably inserted into the hole wall of the circular through hole 212 , and the outside of the pull rod 225 is also inserted into the inner ring of the return spring 223 , and the return spring 223 is located in the square cavity 213 .

[0033] Move the crossbeam 3 to allow the crossbeam 3 to drive the connecting column 243 and the limiting plate 241 to move, so that the limiting plate 241 is inserted into the accommodating groove 211, and at the same time, the outer part of the connecting column 243 slides into the U-shaped groove 214. When the connecting column 243 slides downward, the outer part of the connecting column 243 squeezes the inclined surface 221, thereby causing the limiting block 222 to retract into the square cavity 213. When the limiting block 222 retracts into the square cavity 213, the limiting block 222 will compress the return spring 223. When the connecting column 243 slides into the bottom of the U-shaped groove 214, the return spring 223 pushes the limiting block 222 to extend out of the square cavity 213. Under the obstruction of the limiting block 222 and the limiting plate 241, the connecting column 243 cannot be separated from the mounting block 21. In this way, the connection between the crossbeam 3 and the column 1 is completed. The whole process is quick and convenient without the need to use bolts.

[0034] The buffer protection member 23 includes: a buffer spring 231 and a movable plate 232, the two sides of the movable plate 232 are slidably connected to the two sides of the accommodating groove 211, the outside of the movable plate 232 is fixedly connected to one end of the buffer spring 231, and the other end of the buffer spring 231 is fixedly connected to the groove wall of the accommodating groove 211.

[0035] When the vehicle collides with the cross beam 3, the vehicle hits the cross beam 3, causing the cross beam 3 to push the limit plate 241 through the connecting column 243, and the limit plate 241 pushes the movable plate 232 to move in the direction of the buffer spring 231, so that the movable plate 232 compresses the buffer spring 231, and then the buffer spring 231 plays a role in buffering and absorbing energy to reduce the damage to the vehicle.

[0036] The working principle of the utility model is as follows: since the end of the connecting column 243 is fixedly connected to the outside of the cross beam 3, during installation, it is only necessary to move the cross beam 3 to allow the cross beam 3 to drive the connecting column 243 and the limiting plate 241 to move, so that the limiting plate 241 is inserted into the receiving groove 211, and at the same time, the outside of the connecting column 243 slides into the U-shaped groove 214. When the connecting column 243 slides downward, the outside of the connecting column 243 presses the inclined surface 221, thereby causing the limiting block 222 to retract into the square cavity 213. When the limiting block 222 retracts into the square cavity 213, the limiting block 222 will compress the reset spring 223, and when the connecting column 243 slides into the U-shaped groove 214, the limiting block 222 will compress the reset spring 223. When the vehicle is at the bottom of the groove, the return spring 223 pushes the limit block 222 to extend out of the square cavity 213. Under the obstruction of the limit block 222 and the limit plate 241, the connecting column 243 cannot be separated from the mounting block 21, so that the connection between the beam 3 and the column 1 is completed. The whole process is quick and convenient, and no bolts are required. When the vehicle collides with the beam 3, the vehicle hits the beam 3, so that the beam 3 pushes the limit plate 241 through the connecting column 243, and the limit plate 241 pushes the movable plate 232 to move in the direction of the buffer spring 231, so that the movable plate 232 compresses the buffer spring 231, and then the buffer spring 231 plays a role in buffering and energy absorption to reduce the damage to the vehicle.
