Abstract

The invention discloses a mechanical stopping device for a home elevator. The mechanical stopping device for the home elevator comprises a fixed plate, an in-situ switch, a working switch and a transverse guiding part are arranged on the fixed plate, a sliding sinker bar is arranged in the transverse guiding part and fixedly provided with a sinker bow, and a part of the sinker bow is positioned between the in-situ switch and the working switch and used for being matched with the in-situ switch and the working switch. According to the mechanical stopping device, the sliding sinker bar and the transverse guiding part are matched to form a withdrawal structure, so that the whole stopping device is small in volume, compact in structure, and small in occupied space in installation, and has enough safety.

Description

technical field [0001] The invention relates to the technical field of home elevators, and more specifically relates to a mechanical stop device for home elevator maintenance. Background technique [0002] With the development of urbanization, the market of home elevators is developing very fast. In order to ensure the personal safety of maintenance personnel during the repair and maintenance of home elevators, the General Administration of Quality Supervision, Inspection and Quarantine and the Standardization Committee issued GB in May 2008. / T21739-2008 "Manufacturing and Installation Specifications for Home Elevators", this specification has clear regulations on the top floor and pit space of home elevators. When the top floor and pit space of home elevators cannot ensure the safety of maintenance personnel, it is necessary to A mechanical stop is installed as an auxiliary device to ensure this safe space. [0003] The patent application number is CN201120350578.1, and t...
