[0021] A fall-proof gas spring comprises a gas spring body, which comprises a pressure cylinder 1 and a piston rod 2. A collar 5 is detachably mounted on the outer side of the upper end of the pressure cylinder 1. A plurality of evenly distributed inclined plane blocks 6 are arranged on the upper end of the collar 5. A spring 9 is arranged on one side of the inclined plane block 6. A connecting rod 10 is fastened to the upper end of the inclined plane block 6. An arc-shaped clamping plate 11 is fastened to the end of the connecting rod 10 away from the inclined plane block 6. A moving ring 12 is arranged above the end of the collar 5. The moving ring 12 reciprocates linearly along the axis of the collar 5 to drive the inclined plane blocks 6 to move synchronously toward or away from each other.

[0022] Specifically, the collar 5 is fixedly installed on the outer side of the upper end of the pressure cylinder 1, and then after the piston rod 2 is extended and retracted, the movable ring 12 moves linearly along the axis of the collar 5 and squeezes the inclined surface of the inclined surface block 6 at the same time. The inclined surface block 6 is squeezed and moves synchronously toward each other and stretches the spring 9. The inclined surface block 6 drives the arc clamping plate 11 to move synchronously toward each other through the connecting rod 10 to clamp the outer side of the piston rod 2. If the piston rod 2 fails and falls, the clamping of the arc clamping plate 11 can ensure that the position of the piston rod 2 remains unchanged and protect the supported object from damage. The purpose of this design is to clamp and fix the piston rod 2 through the synchronous movement of the arc clamping plate 11 to ensure that the piston rod 2 does not fall due to failure and avoid damage to the supported object. In addition, the collar 5 can be disassembled for easy maintenance.

[0023] Further, such as Figure 1-3 As shown, the following preferred technical solutions are provided:

[0024] A limit ring 3 is fixedly connected to the outer side of the upper end of the pressure cylinder 1, and a rubber gasket 4 is attached to the upper end of the limit ring 3. The outer side of the upper end of the pressure cylinder 1 is threadedly connected to the inner side of the collar 5. The purpose of this design is to ensure that the collar 5 can be disassembled and assembled on the outer side of the upper end of the pressure cylinder 1, and the deformation of the rubber gasket 4 is used to improve the installation stability of the collar 5.

[0025] Further, such as Figure 1-4 As shown, the following preferred technical solutions are provided:

[0026] A fixing plate 8 is provided on one side of the inclined plane block 6, and the fixing plate 8 is fixedly connected to the upper end of the collar 5. A sliding rod 7 is fixedly connected to the side of the inclined plane block 6. The sliding rod 7 is slidably connected to the inside of the fixing plate 8, and the inclined plane block 6 is slidably connected to the upper end of the collar 5. A spring 9 is sleeved on the outer side of the sliding rod 7, and the two ends of the spring 9 are respectively fixedly connected to the side of the inclined plane block 6 and the side of the fixing plate 8. The purpose of such design is to ensure that when the inclined plane block 6 is squeezed or pulled by the spring 9 to restore its deformation, it can drive the arc-shaped clamping plate 11 to move toward or away synchronously.

[0027] Further, such as Figure 1-4As shown, the following preferred technical solutions are provided:

[0028] A plurality of evenly distributed fixed columns 13 are fixedly connected to the upper end of the collar 5, and the fixed columns 13 are slidably connected to the inside of the moving ring 12. A motor 15 is also fixedly installed on the upper end of the collar 5, and a screw rod 14 is fixedly connected to the output end of the motor 15. The screw rod 14 is threadedly connected to the inside of the moving ring 12, and the moving ring 12 is in contact with the inclined surface block 6. The purpose of such design is that the motor 15 drives the screw rod 14 to rotate, thereby driving the moving ring 12 to reciprocate in a straight line, and then driving the inclined surface block 6 to move toward or away synchronously.

[0029] Further, such as Figure 2 As shown, the following preferred technical solutions are provided:

[0030] An anti-slip pad is attached to the inner side of the arc-shaped clamping plate 11 . The purpose of this design is to improve the clamping stability of the arc-shaped clamping plate 11 .

[0032] The outer side of the collar 5 is formed with a plurality of evenly distributed anti-skid protrusions 16. The purpose of such design is to facilitate the rotation of the collar 5 and improve the anti-skid performance.

[0033] To summarize: the collar 5 is fixedly installed on the outside of the upper end of the pressure cylinder 1, and then after the piston rod 2 is extended and retracted, the movable ring 12 moves linearly along the axis of the collar 5 and squeezes the inclined surface of the inclined surface block 6 at the same time. The inclined surface block 6 is squeezed and moves synchronously toward each other and stretches the spring 9. The inclined surface block 6 drives the arc clamping plate 11 through the connecting rod 10 to move synchronously toward each other to clamp the outside of the piston rod 2. If the piston rod 2 fails and falls, the clamping of the arc clamping plate 11 can ensure that the position of the piston rod 2 remains unchanged and protect the supported object from damage. The purpose of this design is to clamp and fix the piston rod 2 through the synchronous movement of the arc clamping plate 11 to ensure that the piston rod 2 does not fall due to failure and to avoid damage to the supported object. In addition, the collar 5 can be disassembled for easy maintenance.
