Description

A small home elevator

technical field

The invention relates to an elevator, in particular to a small household elevator.

Background technique

Elevator refers to the transportation equipment used to carry people and goods on certain floors in the service and building. With the development of my country's economy and the aging problem is becoming more and more serious, more and more people want to install home elevators. However, At present, it is not common to install home elevators in our country. The main reason is that the size of existing elevators is too large. Most of them adopt elevator structures with shafts, machine rooms, and foundation pits. An elevator with a car size of 0.8m×0.8m , the outer dimension of the elevator must exceed 1.3m×1.3m, and the traditional elevator technology is complicated, which is not easy to install in existing houses. In the current home elevator design, how to fully enlarge the car area and reduce the area of the outer frame within the limited shaft area to provide customers with the most comfortable riding space is the main research direction of elevator engineers.

Contents of the invention

The present invention provides a small household elevator that takes up little space in the hoistway and has an ingenious overall structure.

The technical solution adopted by the present invention to solve its technical problems is:
