A support body 10 is provided at one end of the mounting frame 5 away from the two connecting frames 4, the top of the mounting plate 9 near the left and right sides is fixedly connected with a connecting column 1, the tops of the two connecting columns 1 are fixedly connected with a connecting plate 16, the tops of the two connecting plates 16 near the periphery are fixedly installed with a hollow cylinder 11, the top centers of the two connecting plates 16 are fixedly installed with a damper 15, the tops of the two connecting plates 16 near the center are fixedly connected with a shock-absorbing spring 14, the tops of the two shock-absorbing springs 14 are fixedly installed with a mounting block 13, and the tops of the two mounting blocks 13 are fixedly connected with a limiting plate 12.

Specifically, the interiors of the two sliders 17 and the interiors of the two springs 7 are movably sleeved with the outer surface of the slide bar 3 near the left and right sides, respectively.

In this embodiment, it is convenient to move along the slide bar 3 after being subjected to subsequent force.

Specifically, rubber rings 18 are fixedly installed on the outer surface of the slide rod 3 close to the left and right sides, and opposite ends of the two rubber rings 18 are fixedly connected to adjacent ends of the two connecting seats 2 respectively.

Specifically, the rubber ring 18 can play a buffering role when the slider 17 contacts the connecting seat 2 along the sliding rod 3 , thereby reducing damage to the connecting seat 2 .

In this embodiment, it is convenient for the subsequent L-shaped mounting frame 5 to swing up and down, so that the force on the top of the support body 10 is buffered.

Specifically, the two dampers 15 are respectively located inside the two hollow cylinders 11, the two shock-absorbing springs 14 are respectively located inside the two hollow cylinders 11, the two dampers 15 are located inside the shock-absorbing springs 14, and the tops of the output ends of the two dampers 15 are respectively fixedly connected to the bottoms of the two mounting blocks 13.

In this embodiment, the damper 15 and the shock absorbing spring 14 are protected.

Specifically, the surfaces of the two mounting blocks 13 are movably sleeved with the interiors of the two hollow cylinders 11 .

Specifically, the tops of the two limiting plates 12 are fixedly connected to the bottom of the support body 10 near the left and right sides.

In this embodiment, the support body 10 can be limited in position, and the support body 10 can be limited in position while improving the shock absorption effect.

When in use, the object to be installed is installed or placed on the support body 10. When the support body 10 is affected by vibration, the pressure is transmitted to the two L-shaped mounting frames 5 and the two limit plates 12. The force of the L-shaped mounting frames 5 is transmitted to the connecting frame 4, and the two sliders 17 are pushed to move along the slide rod 3 toward the adjacent connecting seat 2. If the two sliders 17 contact the adjacent rubber rings 18 before contacting the adjacent connecting seat 2, the rubber rings 18 will buffer the impact force of the sliders 17, thereby extending the service life of the two connecting seats 2. The two sliders 17 slide to the opposite side to stretch the spring 7. When the sliders 17 contact the spring 7 When the tensile force decreases, the spring 7 uses its own elasticity to pull the slider 17 back. When the spring 7 and the slider 17 are pulled back and forth, the vibration of the support body 10 is buffered. The buffering can reduce the pressure of the vibration on the shock-absorbing spring 14 and the damper 15, and extend the service life of the shock-absorbing spring 14 and the damper 15. At the same time, the pressure is transmitted to the mounting blocks 13 through the two limit plates 12 respectively. When under pressure, the two mounting blocks 13 retract into the interior of the hollow cylinder 11, and then press toward the shock-absorbing spring 14 and the damper 15. The pressure is dispersed and absorbed by the shock-absorbing spring 14 and the damper 15, thereby improving the shock-absorbing effect of the support body 10.

In summary, the rail shock-absorbing support, by providing the spring 7, slider 17, slide bar 3 and L-shaped mounting frame 5, can buffer the vibration force exerted on the support body 10, and also reduce the direct impact of the vibration on the shock-absorbing spring 14 and the damper 15, thereby extending the service life of the shock-absorbing spring 14 and the damper 15. By providing the shock-absorbing spring 14, the damper 15 and the limiting plate 12, the shock-absorbing spring 14 can absorb energy when impacted and convert it into mechanical energy, thereby reducing vibration, making the vibration amplitude smaller and keeping it stable. The damper 15 can reduce the rebound force of the vehicle body when it is hit, thereby reducing the impact force exerted on the vehicle body and improving the riding comfort. The limiting plate 12 indirectly connects the mounting block 13 of the support body 10, the shock-absorbing spring 14, the damper 15 and the connecting column 1, thereby limiting the support body 10, preventing the support body 10 from being separated from the limit of the two L-shaped mounting frames 5 when vibrated, thereby avoiding affecting subsequent use. The rubber ring 18 can buffer the impact of the slider 17 on the connecting seat 2, reduce the collision damage between the slider 17 and the connecting seat 2, and extend the service life of the slider 17 and the connecting seat 2.
