[0023] Specifically, such as Figure 6 As shown, the rear end of the connecting column 20 is connected to a movable support block 21, and the side of the movable support block 21 is connected to a reset elastic member 22. The rear end of the movable support block 21 is provided with a guide slide 23, and the movable support block 21 is slidably connected to the guide slide 23.

The push slider 16 is fixedly connected to the push plate 15. The push slider 16 is set at the bottom end of the push plate 15 and can slide on the outer side of the slide rail 17. By sliding, it spreads to both sides and squeezes the protective inner plate 27.

[0025] A guide adjustment assembly is provided on the inner side of the protective mat box 1, and the guide adjustment assembly includes a push plate 7, a guide block 9 is provided on the inner side of the push plate 7, and a threaded guide groove 11 is provided on the inner side of the guide block 9, and a retaining spring 12 is provided on the inner side of the threaded guide groove 11. The guide adjustment assembly is used to disperse the impact force during a collision; Specifically, such as Figure 7 As shown, the push plate 7 is fixedly connected to the upper and lower sides of the rear end of the contact baffle 3, and an inclined slide groove 8 is opened on the inner side of the push plate 7. The inclined slide groove 8 is used for sliding guidance of the guide block 9. After the contact baffle 3 is collided, it can approach the protective pad box 1, and then the guide block 9 slides obliquely rearward inside the inclined slide groove 8, adapting to the rotation adjustment of the threaded guide groove 11.

[0026] Specifically, such as Figure 7 As shown, a rotating support rod 10 is connected to the middle part of the inner side of the protective pad box 1, and threaded guide grooves 11 are provided on the upper and lower sides of the outer wall of the rotating support rod 10. The threaded guide grooves 11 are adapted to the guide blocks 9. A retaining spring 12 is connected to the outer side of the rotating support rod 10. The rotating support rod 10 is connected to the rotating rod with the threaded guide grooves 11 as a rotating shaft. The retaining spring 12 on the inside can be rotated and tightened during rotation. The elastic force generated during the tightening process is used to offset part of the collision pressure, which has certain protective performance.

[0027] Side extension protection components are provided on both sides of the contact baffle 3. The side extension protection components include a rotating connecting rod 25, and a protective inner plate 27 is provided on the inner side of the rotating connecting rod 25. A protective outer plate 30 is provided on the inner side of the protective inner plate 27. The side extension protection components are used for side extension protection during collision.

[0028] Specifically, such as Figure 2 As shown, rotating support blocks 24 are installed on both ends of the contact baffle 3, and fixed blocks 34 are connected to the upper and lower ends of the rotating support block 24. The rear end of the rotating support block 24 is connected to a cutting knife 35. The cutting knife 35 squeezes the connecting rope 33 after it rotates to cut it.

[0029] Specifically, such as Figure 8As shown, the rotating connecting rod 25 is connected to the inner side of the rotating support block 24, and the outer side of the rotating connecting rod 25 is connected with a retaining spring 26, and a straight guide groove 28 is provided on the inner side of the protective inner plate 27. The inner rear end of the straight guide groove 28 is fixedly connected with a magnetic stop block 29. The connection of the retaining spring 26 is used to limit the protective inner plate 27, and the straight guide groove 28 is used for sliding guidance of the protective outer plate 30.

[0030] Specifically, such as Figure 2 and Figure 8 As shown, a guide iron slider 31 is provided on the inner side of the protective outer plate 30, and a pushing elastic member 32 is connected to the rear end of the guide iron slider 31. Connecting ropes 33 are connected to the upper and lower ends of the protective outer plate 30. When the protective inner plate 27 rotates, the connecting rope 33 approaches the cutting knife 35 until it is cut off. At this time, the elastic force of the pushing elastic member 32 drives the guide iron slider 31 to slide on the inner side of the straight guide groove 28 until it is adsorbed and fixed at the magnetic stop block 29, thereby extending the protection of the protective inner plate 27.

[0031] In this embodiment: while the anti-collision buffer device is being buffered by the collision, the push plate 15 is driven to squeeze the protective inner plate 27 to both sides for expansion, and the protective outer plate 30 is ejected by the elastic force on the inner side of the protective inner plate 27, thereby further increasing the protection area and improving the protection area during collision. When the contact baffle 3 is collided, the movement of the push plate 7 drives the rotating support rod 10 to rotate, and the inner retaining spring 12 is deformed by the force, and a part of the pressure generated by the collision is offset by the elastic force of the deformed product, and the movable support block 21 is connected with the inner elastic connecting rod 18 for rotation, adjustment and extrusion, so that the unidirectional collision force can be dispersed for easy protection.

[0032] The specific scheme is as follows: first, the anti-collision buffer device is installed on the anti-collision buffer vehicle through the rear guard plate 2, and its position is adjusted by the cylinder system on the anti-collision buffer vehicle. During use, the contact baffle 3 is pasted with a warning sticker at the rear end for protection. When it is hit, it first collides with the contact baffle 3. At this time, the arc tube 6 first absorbs the force of the collision, offsets a part of it and then breaks. At this time, the contact baffle 3 is close to the protective pad box 1, and at the same time, the guide block 9 on the inside of the push plate 7 is adapted to the threaded guide groove 11 on the inside of the rotating support rod 10 for movement and adjustment, driving the rotating support rod 10 to rotate, and synchronously driving the rotating plates 13 at the upper and lower ends to rotate, and under the support and push of the rotating adjustment rods 14 in different directions on both sides, the push plate 15 slides to both sides to squeeze the protective inner plate 27. When the contact baffle 3 approaches the protective pad box 1, the elastic connecting rod 18 moves to the protective pad box 1 is squeezed inside. At this time, the movable support block 21 squeezes the reset elastic member 22 to both sides under the rotation connection, which can disperse and buffer the force in one direction. After the protective inner plate 27 is squeezed, it can rotate under the connection of the rotating support block 24 and the rotating connecting rod 25. At this time, the protective inner plate 27 is extended to both sides at a certain angle to increase the protection area. While the protective inner plate 27 rotates, the connecting rope 33 approaches the cutting knife 35. When the connecting rope 33 breaks, the pushing elastic member 32 on the inside of the protective outer plate 30 loses the traction tension. The elastic force will drive the guide iron slider 31 to slide inside the straight guide groove 28, and the protective outer plate 30 will continue to pop out along the edge of the protective inner plate 27 until the guide iron slider 31 contacts the magnetic stop block 29 and is adsorbed, thereby increasing the protection area and increasing the protection range for the front-end construction personnel.

[0033] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative; within the scope of the present invention, the technical features of the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.

[0034] The present invention is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
