[0029] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the utility model.

[0030] Please refer to Figures 1-3 The utility model provides a kind of technical scheme: a sill device applied to straight elevator, comprising:

[0031] Sill support frame 1 is provided with mounting groove 2 on the sill support frame 1;

[0032] Buffer component 3 is attached to the surface of mounting groove 2;

[0033] Sill body 4 is detachably connected on the sill support frame 1 by at least two fastening components 5, the buffer component 3 is located between the sill support frame 1 and the sill body 4, and the surface of the sill body 4 is provided with wear-resistant coating.
