Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, the utility model provides a buffer device for elevator base, including the buffering piston rod 8 that casing 1 and its inside slip were provided with, on casing 1's lower extreme fixed connection to base 2, the upper end fixedly connected with buffering roof 4 of buffering piston rod 8, the fixed dust-retaining sleeve 5 that is provided with in 4 downside borders of buffering roof, the fixed outer lasso 7 that is provided with in the upper end outside of casing 1, casing 1 between outer lasso 7 and the buffering roof 4 and the nested spring 9 in the buffering piston rod 8 outside, outer lasso 7 and dust-retaining sleeve 5 adopt clearance fit each other.
The outer side of the outer collar 7 is provided with a rubber collar 6 for ensuring a sealing of the contact portion between the outer collar 7 and the dust sleeve 5.
More than three reinforcing ribs 3 which are uniformly distributed by taking the shell 1 as the center are fixedly connected between the shell 1 and the base 2. The stability of being connected between casing 1 and the base 2 can be increased, the slope because of the atress is too big between casing 1 and the base 2 is avoided.
