Household elevator with automatic telescopic toe guard

Abstract

The invention relates to the technical field of elevators, in particular to a household elevator with an automatic telescopic toe guard. The household elevator with the automatic telescopic toe guardcomprises a front positioning plate and a rear positioning plate which are arranged at the bottom of a lift car, side plates located on the two sides of the bottom of the lift car are arranged betweenthe front positioning plate and the rear positioning plate, a buffer plate is rotationally connected to the side plates through positioning shafts, a buffer shell with a second air cavity is arrangedon the side, close to the buffer plate, of the rear positioning plate, a second piston is slidably connected into the second air cavity, a buffer rod used for driving the second piston to move is arranged on the buffer plate, a first air cavity is formed in the buffer plate, a first piston is slidably connected into the first air cavity, the first piston is connected with a telescopic plate extending to the position below the buffer plate, and the first air cavity and the second air cavity are connected through an air guide pipe. According to the household elevator with the automatic telescopic toe guard, the toe guard is telescopic and suitable for shallow shaft pits, and when a passenger kicks on the toe guard by stretching the foot accidentally, great pain cannot be caused.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a home elevator with an automatic retractable toe guard. Background technique [0002] The national standard GB7588-2003 puts forward relevant requirements for elevator toe guards: each elevator should be equipped with toe guards, and the width should not be less than the entire clear width of the entrance of the elevator landing door, and the height should not be less than 0.75m. Its lowest position shall not be lower than 0.5m from the pit floor. [0003] The existing toe guard has a simple structure and is a non-retractable guard. The elevator toe guard is fixedly connected to the car sill bracket at the front end of the car floor to reduce the distance between the car floor and the floor door sill , effectively prevent people from accidentally falling into the elevator shaft when getting out of the elevator, and can meet the needs of most elevator shafts at present.

AI Technical Summary

Problems solved by technology

[0007] The present invention is mainly aimed at the fact that the pits of many domestic elevators are generally shallow. When the depth of the well pit is small, the traditional car toe guards will touch the ground of the pit when the elevator runs to the bottom, causing It is damaged and cannot meet the requirements of shallow pits; moreover, the existing toe guards are fixed on the car. When passengers accidentally stretch their feet and kick on the toe guards, it will cause greater pain and affect the experience of passengers. The problem is to provide a home elevator with automatic retractable toe guards, which are retractable and suitable for shallow well pits, and when passengers accidentally stretch their feet and kick on the toe guards, there will be no large damage. feeling of pain
