[0002] A shock absorber is an important device widely used in many fields. Its functions include reducing impact force and protecting equipment or personnel safety.

[0023] In this embodiment, a second spring 13 is provided at the lower end of the top plate 12. One end of the second spring 13 is fixedly connected to the top plate 12, and the other end of the second spring 13 is fixedly connected to the second gear 9.

[0024] Specifically, the second spring 13 undergoes elastic deformation under stress to mitigate the impact force generated during the collision.

[0025] In this embodiment, a rotating ring 14 is rotatably connected to the outer side of the top plate 12. A second electric telescopic rod 15 is installed at the lower end of the rotating ring 14. The output shaft of the second electric telescopic rod 15 is fixedly connected to a storage box 16. A rotating rod 17 is slidably connected to the inner side of the storage box 16. The rotating rod 17 is made of soft material. The upper end of the rotating rod 17 is fixedly connected to the rotating ring 14, and the lower end of the rotating rod 17 is fixedly connected to the first gear 8.

[0026] Specifically, the rotating rod 17 drives the rotating ring 14 to rotate on the outside of the top plate 12, and at the same time drives the output shaft of the second electric telescopic rod 15 to extend, causing the storage box 16 to move along the rotating rod 17.

[0027] In this embodiment, a groove is provided on the outer side of the rotating rod 17, and a limiting strip 19 is slidably connected to the inner side of the groove. A blade 18 is fixedly connected to the outer side of the limiting strip 19, and the upper and lower ends of the blade 18 are in contact with the storage box 16.

[0028] Specifically, the chute drives the limit bar 19 to rotate, and the limit bar 19 drives the blade 18 to rotate, stirring the anti-rust coating inside the storage box 16.

[0030] Specifically, temperature sensor 21 detects the ambient temperature, and nozzle 20 sprays an anti-rust coating onto the second spring 13.

[0031] In this embodiment, a mounting plate 22 is fixedly connected to the outer side of the support ring 3, and a motor 23 is mounted on the upper end of the mounting plate 22. A third gear 24 is fixedly connected to the output shaft of the motor 23, and the outer side of the third gear 24 meshes with the double-sided gear 7.

[0032] Specifically, the motor 23, which is fixedly mounted on the mounting plate 22, is driven to rotate. The output shaft of the motor 23 drives the third gear 24 to rotate, and the third gear 24 drives the double-sided gear 7 to rotate.

[0033] Working principle: In use, the base pad 1 is installed at the bottom of the elevator shaft, driving the output shafts of the two sets of first electric telescopic rods 2 to extend. The output shafts of the first electric telescopic rods 2 drive the support ring 3 to move, and the support ring 3 drives the slide rod 4 below to move. The slide rod 4 moves inside the limit sleeve 5, causing the first spring 6 to elastically deform according to the position of the support ring 3. The output shafts of the first electric telescopic rods 2 are stopped according to the working conditions. The base 10 and the top plate 12 are used to fix the position of the second spring 13. The lower end of the guide cylinder 11 is connected to the slide rod 4. When the elevator car falls out of control and exceeds the lower limit, the bottom of the elevator contacts the top plate 12. The top plate 12 drives the guide cylinder 11 to slide inside the base 10. The second spring 13 is subjected to force and undergoes elastic deformation to alleviate the impact force generated during the impact. At the same time, the first spring 6 is also subjected to force and undergoes elastic deformation to further reduce the impact force. When the weather is cold in winter, the temperature sensor 21 detects the ambient temperature and drives the motor 23 fixedly installed by the mounting plate 22 to operate through the controller. The output shaft of motor 23 drives the third gear 24 to rotate, which in turn drives the double-sided gear 7 to rotate. The double-sided gear 7 further drives the first gear 8 to rotate outside the second gear 9. At this time, the first gear 8 can both revolve and rotate on its own axis. While the first gear 8 is rotating, it drives the rotating ring 14 to rotate outside the top plate 12 through the rotating rod 17. At the same time, it drives the output shaft of the second electric telescopic rod 15 to extend and move the storage box 16 along the rotating rod 17. The first gear 8 revolves around the second gear 9, and the output shaft of the second electric telescopic rod 15 extends and retracts, driving the nozzle 20 to move around 13, evenly spraying the anti-rust coating onto the second spring 13 to prevent the spring from rusting due to condensation and humid air. When the first gear 8 drives the rotating rod 17 to rotate, the outer groove of the first gear 8 drives the limiting strip 19 to rotate. The limiting strip 19 drives the blade 18 to rotate and stir the anti-rust coating inside the storage box 16, preventing it from settling and solidifying due to cold weather, reducing the workload of the workers and increasing the practicality of the device.

[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
