When the mounting plate 4 is moved downward by the impact, the support rods 6 are impacted to bend the two movable rods 61 to each other, so that the support rods 6 are separated from the support plate 5, thereby smoothly tilting the support plate 5 downward. When two movable rods 61 buckle each other, can play the cushioning effect with the impact that receives on the mounting panel 4 to the power on bracing piece 6 striking ground reduces, makes toppling over of mounting panel 4 can be more steady.
Referring to fig. 5, the support plate 5 is further provided with a blocking plate 7 for blocking a vehicle from leaving the apron 1, the blocking plate 7 being mounted to the support plate 5. The supporting plate 5 is provided with a sliding groove 51 for installing the arresting plate 7, and the arresting plate 7 is slidably connected in the sliding groove 51. One end of the barrier plate 7 close to the bottom wall of the sliding chute 51 is abutted with a striking rod 8, and one end of the striking rod 8 extends out of the support plate 5. When the support plate 5 impacts the ground, the end of the impact rod 8 extending out of the support plate 5 abuts against the ground, so that the barrier plate 7 is driven to partially extend out of the sliding groove 51 to block the vehicle.
Referring to fig. 5, one end of the striker 8 located in the slide groove 51 is connected with a first stopper 81, and when the striker 8 rotates downward along with the support plate 5, the first stopper 81 abuts against the bottom wall of the slide groove 51, so that the striker 8 is prevented from being detached from the slide groove 51. The part of the barrier plate 7 located in the sliding groove 51 is connected with a second limiting block 71, and the sliding groove 51 is internally and tightly abutted with a stop block 52. The part of the receiving plate 9 located in the sliding groove 51 is connected with a third limiting block 93, and both the second limiting block 71 and the third limiting block 93 can be abutted against the stopper 52, so that the blocking plate 7 and the receiving plate 9 are prevented from being completely separated from the sliding groove 51.
Referring to fig. 5 and 6, a spring 53 for accelerating the arresting plate 7 to pop out of the chute 51 is installed in the chute 51, one end of the spring 53 abuts against the first stopper 81, and the other end of the spring 53 abuts against one side of the arresting plate 7 close to the striker 8. One end of the supporting plate 5 close to the surrounding plate 1 is clamped with a clamping block 54 for limiting the blocking plate 7 to slide out of the sliding groove 51, and when the clamping block 54 is clamped at the opening of the sliding groove 51, the spring 53 is in a compressed state. When the impact rod 8 impacts the ground, the blocking plate 7 impacts the blocking block 54, the elastic force of the spring 53 can drive the blocking plate 7 to slide out of the sliding groove 51 more quickly, and more parts of the blocking plate 7 can also slide out of the sliding groove 51, so that the blocking plate 7 can better intercept the vehicle.

when the vehicle is out of control to impact the coaming 1, the upper end of the coaming 1 inclines downwards towards the direction of a construction site to impact the mounting plate 4, the coaming 1 supports against the stress end 31 of the resistance-increasing ring 3, and the stress end 32 of the resistance-increasing ring 3 drives the extension end to penetrate out of the through groove 11. In the process that the mounting plate 4 is along with the continuous downward inclination of the coaming 1, the coaming 1 continuously applies pressure to the stress end 31 of the resistance-increasing ring 3, so that the extending ends 32 of the resistance-increasing rings 3 penetrate out of the through groove 11, and when the wheels of a vehicle roll the coaming 1, the extending ends 32 increase the friction force on the surface of the coaming 1, thereby reducing the speed of the vehicle.
When the impact rod 8 impacts the ground, the part of the coaming 1 which is subjected to the impact force is released, and when the support rod 6 impacts the ground, the part of the coaming 1 which is subjected to the impact force is further released.
When the impact rod 8 impacts the ground to abut against the ground, the blocking plate 7 impacts the block outside the sliding groove 51, and part of the blocking plate 7 is rapidly ejected out of the supporting plate 5 to block the vehicle impacting the upper enclosing plate 1 with the help of the elastic force of the spring 53. If the barrier plate 7 is impacted by a vehicle, the pressing plate 72 on the barrier plate 7 is impacted to impact the plastic film 92, the plastic film 92 has a buffering effect on the vehicle, and when the plastic film 92 is crushed, the impact force on the barrier plate 7 is released to a certain extent, so that the vehicle can be better prevented from rushing into a construction site.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
