Problems solved by technology

However, there is still a problem in the elevator sill: the noise-absorbing strip is fixedly connected with the disassembly sleeve by glue. When the elevator door panel reciprocates, the noise-absorbing strip is prone to degumming, which affects the normal use of the elevator sill.

Embodiment Construction

[0028] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0029] Such as figure 1 Shown, this elevator sill is made up of sill body 1, sliding sleeve 2, rubber strip 3 etc. Wherein, the middle part of the sill body 1 is recessed downwards to form a strip-shaped chute 1a, and the sliding sleeve 2 is fixed in the chute 1a.

[0030] Specifically, the sliding sleeve 2 is elongated and arranged along the length direction of the sliding slot 1a. The cross section of the sliding sleeve 2 is concave, and the sliding sleeve 2 includes two vertically arranged side plates 2a and a bottom plate 2b between the two side plates 2a. Wherein, the bottom plate 2b is arranged along the horizontal direction, the bottom plate 2b abuts against the bottom wall of the chute 1a, and the bottom plate 2b...

Abstract

The invention provides an elevator sill, and belongs to the technical field of machines. The problem that an existing elevator sill is poor in noise absorbing effect is solved. The elevator sill comprises a sill body with a sliding groove. The sliding groove is in a long-strip shape. A sliding sleeve is fixedly connected in the sliding groove and comprises two side plates vertically arranged and a bottom plate located between the two side plates and horizontally arranged. Long-strip-shaped connecting grooves are formed in the inner side walls of the two side plates and are arranged in the length direction of the sliding groove. The bottom plate is correspondingly provided with connecting blocks matched with the connecting grooves. The connecting blocks are inserted in the connecting grooves in a connected manner. The bottom plate and the side plates are fixed together through welding. Rubber strips are arranged on the inner sides of the two side plates. Each rubber strip comprises a connecting part and an abutting part used for abutting against an elevator door plank. Long-strip-shaped dovetailed grooves are further formed in the inner side walls of the side plates and are arranged in the length direction of the sliding groove. The connecting parts are embedded in the dovetailed grooves. The elevator sill has the beneficial effect of being good in noise absorbing effect.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an elevator sill. Background technique [0002] Currently, elevator sills are fitted with elevator car doors for guidance and support. For the convenience of processing and anti-rust and anti-corrosion, aluminum materials or cast iron parts are generally used. These types of elevator sills have poor wear resistance and produce grooves after long-term wear. The deformation of the grooves seriously hinders the opening and closing of the door, and the opening and closing of doors The sound is loud, and the noise will affect people's normal life and work. [0003] For the above-mentioned problems, people have realized the deficiencies and made improvements, such as a kind of elevator sill with noise reduction effect disclosed in the Chinese patent library [application number: 201420378438.9; authorized announcement number: CN 204057604 U], including the sill Bracket, the sill bracke...
