Description

Technical Field

[0001] The utility model relates to the technical field of protective fences, in particular to a fence with a buffer protection mechanism. Background Technique

[0002] A fence is a common enclosing structure, often used to define boundaries and separate areas. It can clearly demarcate the boundaries between private property and public areas, indicate land ownership or usage rights, and at the same time prevent illegal intrusion. Fences can also be used to prevent wild animals from entering specific areas or to enclose livestock. And some fence designs are beautiful, so they can be used as decorations to enhance the beauty of the environment.

[0003] At present, some existing fences lack a buffer protection mechanism and are more likely to be damaged when impacted, requiring repair or replacement. Moreover, fences without a buffer device cannot effectively absorb the impact force, which may cause more extensive damage due to the impact force.

The second spring can generate a rebound force to resist the impact force after the buffer plate is impacted and drives the first slider to slide inward, thereby reducing the damage to the fence caused by the external impact. Two fence panels can be quickly connected through connecting bent rods. When the threaded screw rod rotates, it can drive the universal wheels to move up and down, so as to retract it when not in use.

Align the third slider with the third chute, quickly splice the railing, pull up the connecting bent rod, so that the first spring is compressed, release the connecting bent rod, and the first spring drives it to move in the reverse direction and snap into the C-shaped elastic plate. The airbag between adjacent railings can enhance the buffering capacity at the connection. Due to the certain elasticity of the C-shaped elastic plate, after being impacted, the connecting bent rod may be squeezed out of the C-shaped elastic plate to prevent adjacent railings from being damaged together.

[0027] 3. A fence with a buffer protection mechanism proposed in the content of the present utility model. Compared with the existing protective fences, through the settings of shock absorbers and shock springs, it is convenient to absorb and consume the energy generated by impacts. The second spring can generate a rebounding force to resist the impact force after the buffer plate is impacted and drives the first slider to slide inward, thereby reducing the damage to the fence caused by external impacts.

Based on the specific embodiments of the present utility model, all other specific embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0036] Reference Figures 1-5 , a specific embodiment provided by the present utility model:

[0037] A fence with a buffer protection mechanism, including a fence panel 1, a buffer plate 2 is provided at the front end of the fence panel 1, shock absorbers 4 are fixedly connected to the four corners at the front end of the fence panel 1, a shock absorption spring 3 is sleeved on the outer wall of the shock absorber 4, one side of the shock absorber 4 and the shock absorption spring 3 are fixedly connected to the buffer plate 2, a first sliding groove 5 is opened at the center of the rear end of the buffer plate 2, two first sliding blocks 6 are slidably connected to both sides inside the first sliding groove 5, a second spring 24 is fixedly connected between the two first sliding blocks 6. The arrangement of the second spring 24 facilitates the inward sliding of the first sliding block 6 when impacted to generate a reaction force to resist the impact force, reducing the damage to the fence caused by the external impact force. Two second sliding blocks 9 are slidably connected to both sides inside the front end of the fence panel 1, two second sliding grooves 8 are opened on both sides of the front end of the fence panel 1, and the second sliding blocks 9 are limited to slide inside the second sliding grooves 8. The arrangement of the second sliding grooves 8 facilitates the sliding of the second sliding blocks 9 inside them through the connecting rod 7 after the first sliding blocks 6 slide. A tension spring 10 is fixedly connected to the side of the second sliding groove 8 away from the center of the fence panel 1, and one side of the tension spring 10 is fixedly connected to the second sliding block 9. The arrangement of the tension spring 10 facilitates driving the second sliding block 9 to move in the reverse direction after the impact force disappears. The first sliding block 6 and the second sliding block 9 are connected by a connecting rod 7. Air bags 11 are fixedly connected to both sides of the front end of the fence panel 1, and an air inlet pipe 12 is fixedly connected to the upper end of the air bag 11. The arrangement of the air inlet pipe 12 facilitates inflating the air bag 11, enhancing the buffering capacity at the connection after inflation;

[0038] A third sliding groove 13 is opened on one side of the fence panel 1, a third sliding block 14 is fixedly connected to the side of the fence panel 1 away from the third sliding groove 13, a fixing plate 15 is fixedly connected to one side of the rear end of the fence panel 1, a connecting bent rod 17 is slidably connected inside the fixing plate 15, a limiting plate 19 is fixedly connected to the lower end of one side of the connecting bent rod 17, a first spring 18 is sleeved on the outer wall of one side of the connecting bent rod 17, the upper end of the first spring 18 is fixedly connected to the fixing plate 15, and the lower end of the first spring 18 is fixedly connected to the limiting plate 19. The arrangement of the first spring 18 facilitates pulling up the connecting bent rod 17 and then driving the connecting bent rod 17 to move in the opposite direction downward. A C-shaped elastic plate 16 is fixedly connected to the side of the rear end of the fence panel 1 away from the fixing plate 15, connecting plates 20 are fixedly connected to both sides of the rear end of the fence panel 1, a threaded screw rod 22 is threadedly connected inside the connecting plate 20, a universal wheel 21 is rotatably connected to the lower end of the threaded screw rod 22, and a rotating rod 23 is fixedly connected to the upper end of the threaded screw rod 22. The arrangement of the threaded screw rod 22 facilitates driving the universal wheel 21 to move up and down after rotation, so as to retract it during use and rotate it out during movement;

[0039] Gripping teeth 25 are fixedly connected to both sides of the lower end of the fence panel 1. The arrangement of the gripping teeth 25 facilitates connection with the ground.

The airbag 11 between adjacent railings 1 can enhance the buffering capacity at the connection. Since the C-shaped elastic plate 16 has a certain elasticity, after being impacted, the connecting bent rod 17 may be squeezed out of the C-shaped elastic plate 16 to prevent adjacent railings 1 from being damaged jointly. When the buffer plate 2 is impacted by the outside world, the shock absorber 4 and the shock-absorbing spring 3 can absorb and consume the energy generated by the impact, so that the fence system maintains a good buffering and protective effect. After the impact force disappears, the shock-absorbing spring 3 can return to its original shape and release the stored energy. When the buffer plate 2 moves under the impact, it will drive the first sliders 6 on both sides to move inward, squeezing the second spring 24 to generate a rebounding force to resist the impact force and reduce the damage of the outside impact force to the fence. At the same time, the connecting rod 7 drives the second slider 9 to move inside the second chute 8, squeezing the tension spring 10. After the impact force disappears, the second spring 24 drives the first slider 6 to move in the reverse direction and return to its original position. When it is necessary to move the fence to other places, rotate the rotating rod 23 to drive the threaded screw rod 22 to rotate, driving the universal wheel 21 to move downward, so as to push the fence to move it.
