Both sides of the upper end of the lower seat 3 and the bottom end of the upper support rod 8 are fixedly installed with protective pads 10, which can reduce the force of the collision when the upper support rod 8 contacts the lower seat 3. The protective pad 10 is a silicone protective pad. The silicone protective pad 10 is made of silicone material, which has certain tension, flexibility, excellent insulation, pressure resistance, high temperature resistance, low temperature resistance, stable chemical properties, environmental protection and safety, and no odor. A slide groove 31 adapted to the lower support rod 9 is opened on one side of the upper end of the lower seat 3, and blocks 61 are fixedly installed on both sides of the upper end of the gasket 6. A slot 21 adapted to the block 61 is opened at the lower end of the upper seat 2, and the block 61 is movably connected to the slot 21 through a fastening nut.

[0028] As an optional technical solution of the present invention, there are two telescopic rods 4 , the upper ends of the two telescopic rods 4 are movably connected to the lower ends of the gaskets 6 , respectively, and the two telescopic rods 4 can ensure the stability of the reinforcement device 1 .

[0029] As an optional technical solution of the present invention: there are two fixing rods 5, the lower ends of the two fixing rods 5 are fixedly connected to the two sides of the upper end of the lower seat 3 respectively, and the two fixing rods 5 can make the reinforcement device 1 more firmly fixed.

[0030] As an optional technical solution of the present invention: there are four gaskets 6, and the four gaskets 6 are movably connected to the upper ends of the telescopic rod 4 and the fixed rod 5 through nuts respectively. The gaskets 6 can ensure that the telescopic rod 4 and the fixed rod 5 will not be in direct contact, thereby reducing the hard friction between the telescopic rod 4 and the fixed rod 5.

[0031] As an optional technical solution of the present invention: there are two upper support rods 8, and the upper ends of the two upper support rods 8 are fixedly connected to the two sides of the lower end of the upper seat 2 respectively. The two upper support rods 8 make the structure more stable.

[0032] As an optional technical solution of the present invention: there are two lower support rods 9, the upper ends of the two lower support rods 9 are fixedly connected to the two sides of the lower end of the elastic block 7 respectively, and the two lower support rods 9 limit the deformation degree of the reinforcement device 1 to prevent the reinforcement device 1 from being damaged due to excessive deformation.

[0033] As an optional technical solution of the present invention: the upper support rod 8 is located on one side of the telescopic rod 4, and the lower support rod 9 is located on one side of the upper support rod 8. Such a position relationship can ensure that the reinforcement device 1 is more stable.

[0034] As an optional technical solution of the present invention: the upper support rod 8 and the lower support rod 9 are both L-shaped. The L-shaped support rod can increase the impact resistance effect while ensuring better stability of the reinforcement device 1. The lower end of the lower support rod 9 is fixedly installed with a limiting block 91.

[0035] As an optional technical solution of the present invention: the limit block 91 is integrally formed with the lower support rod 9, and the limit block 91 can ensure that the lower support rod 9 will not directly pop out of the inside of the slide groove 31 when the spring bounces up, thereby increasing the stability of the reinforcement device 1 and making the reinforcement device 1 more secure. The limit block 91 is located inside the slide groove 31.

[0036] As an optional technical solution of the present invention: the length of the fastening nut is greater than the length of the gasket 6, so that it can be ensured that the fastening nut can fix both blocks 61 to the slot 21, and the fastening nut passes through the slot 21 and the block 61.

[0037] In summary, the bridge base uses an impact-resistant reinforcement device. When in use, when the reinforcement device 1 is subjected to force, the upper seat 2 is forced to move downward, and the upper seat 2 drives the upper support rod 8 and the telescopic rod 4 to move downward at the same time. The telescopic rod 4 enters the interior of the fixed rod 8, and the upper support rod 8 moves downward to compress the compression spring. The elastic block 7 is forced to move downward, and the upper support rod 8 and the elastic block 7 simultaneously move the upper support rod 9 downward. When the upper support rod 8 contacts the lower seat 3, the lower support rod 9 can still move downward, and the lower support rod 9 drives the limit block 91 to move downward in the slide groove 31 to compress the compression spring until the upper support rod 8 contacts the lower seat 3. When the lower support rod 9 and the upper support rod 8 fit together, the reinforcement device 1 is deformed by the impact force. When the force disappears, the compression spring force disappears, and the reinforcement device 1 returns to its original state. Restricted by the limiting block 91, the lower support rod 9 returns to its original position and will not slide out of the interior of the slide groove 31. When it is necessary to remove the gasket 6, the fastening nut is unscrewed, and then the gasket 6 is moved downward to pull the block 61 out of the interior of the slot 21, and the gasket 6 is removed for replacement. Because the fastening nut is installed on the outside, it is more convenient to remove the gasket 6. While removing the gasket 6, the upper seat 2 can also be replaced.

Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.
