Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 are referred to, the utility model provides a kind of technical scheme：A kind of cam-type elevator governor, including bottom plate
1 and first fly jib 7, shell 6 is welded with bottom plate 1, and fast pulley 2 is installed inside shell 6, the middle part of fast pulley 2 is provided with solid
Determine ratchet 3, the outside of fast pulley 2 is mounted with rope sheave 5, and rope sheave 5 and fast pulley 2 are that engineering plastic materials are formed, and fixed
Ratchet 3 is provided with eight in the inner annular of fast pulley 2, and the center of fast pulley 2 is hinged with adjustable spring 4, the front end of adjustable spring 4 and the
The end of two fly jib 13 is hinged, and the middle part of the second fly jib 13 is attached by anchor 8, and the rear end of the first fly jib 7 passes through first
