Description

technical field [0001] The invention relates to a safety device, in particular to a safety gear used for a domestic elevator. Background technique [0002] At present, in order to save space and maximize space utilization, home elevators mostly use a backpack structure, which is very compact. In the limited elevator installation space, not only the counterweight device needs to be placed, but also many elevator safety components, such as safety gear, need to be installed. However, the currently used safety gear has a complex structure and a relatively large volume, which is very inconvenient for the installation of a home elevator, and even needs to occupy a limited space in the shaft. Contents of the invention [0003] The invention provides a safety gear, which has a novel structure, is simple in structure, small in size, takes up little space, is easy to install, and can provide safety guarantee for elevators. [0004] The present invention adopts following technical ...
