Problems solved by technology
The traditional shock-absorbing elevator buffer shaft is directly sleeved on the shock-absorbing shaft, and the shock-absorbing elevator buffer shaft is not provided with a shock-absorbing structure, resulting in damage to many elevator buffer shafts due to the inability to synchronize shock absorption during the shock-absorbing process; And the current elevator buffer shaft is a fully sealed structure. After the shock absorber is sleeved in it, it is not possible to add lubricating oil to the shock absorber.

Embodiment Construction
[0035] The present invention will be further described below in conjunction with drawings and embodiments.
[0036] Examples such as Figure 1 to Figure 9 Shown; an elevator buffer shaft, which includes: a shaft body 1; in the present invention, the shaft body 1 is an alloy shaft body, a stainless steel shaft body or an iron shaft body. Because the alloy shaft body, stainless steel shaft body or iron shaft body is not only low in cost, but also has a long service life.
[0037] The shaft body 1 is provided with a cavity part for sheathing and fixing the external damping shaft;
[0038] Also includes a shock absorbing structure;
[0039] The shock absorbing structure is located at the upper end of the shaft body 1 and is fixedly connected with the shaft body 1;
[0040] The shock absorbing structure includes a fixed shaft 7 and a first elastic component 5; the first elastic component 5 is located outside the fixed shaft 7;
[0041] The first elastic component 5 is located a...

The invention discloses an elevator buffer shaft, which comprises: a shaft body; inside the shaft body, there is a cavity for sheathing and fixing an external shock absorbing shaft; and a shock absorbing structure; the shock absorbing structure is located at the upper end of the shaft body And it is fixedly connected with the shaft body; the shock absorbing structure includes a fixed shaft and a first elastic component; the first elastic component is located outside the fixed shaft; the first elastic component is located at the upper end of the shaft body and is fixedly connected with the shaft body. The invention is provided with an oiling structure, which can add lubricating oil to the damping shaft sleeved in the cavity of the shaft body; the invention is also provided with an elastic fixing seat and a spring; the spring is fixed between the elastic fixing seats, and the to the damping effect.
Description
technical field [0001] The invention relates to the technical field of shock absorption, in particular to an elevator buffer shaft. Background technique [0002] Due to the advancement of modern technology, the standard of living is improving day by day, and the required product quality is also correspondingly improved. In terms of elevator buffer shafts, not only is it required to be strong and durable, but it must also be lightweight. The traditional shock-absorbing elevator buffer shaft is directly sleeved on the shock-absorbing shaft, and the shock-absorbing elevator buffer shaft is not provided with a shock-absorbing structure, resulting in damage to many elevator buffer shafts due to the inability to synchronize shock absorption during the shock-absorbing process; And the present elevator buffer shaft is a fully sealed structure, and after the shock absorber is sleeved therein, lubricating oil cannot be added to the shock absorber. Contents of the invention [0003]...
