Bar, makes external thread rod top be fixed in nut so that light curtain is fixing in the enclosure, fixes afterwards
The calvus of plate is fixed in elevator door so that light curtain can fixedly secure, and ensures that elevator is normally pacified
The advantage of row for the national games.
The technology solution of the present invention is as follows:
A kind of elevator light curtain, including shell, light curtain and rear fixed plate, described shell be by
Some small shells form, and light curtain is pasted with a straight plate, is fixed with an active in the middle of straight plate
Axle, driving shaft top is provided with an interior hexagonal counterbore, driving shaft is fixed with a driving gear,
Straight plate is respectively provided on two sides with bearing, bearing is inserted with an external thread rod, external thread rod is rotary with
One driven gear, the driven gear of both sides engages each other with driving gear, external thread rod top
Being inserted in nut, nut is fixed on inside rear fixed plate, and rear fixed plate is provided with calvus.
In technique scheme, the small shell of described shell is in-between by bottom small shell
Shell fragment is stuck in the groove of top small shell.
In technique scheme, described driving shaft and driving gear, external thread rod and driven gear
Between be fixed by bonded.
In technique scheme, the hand of spiral of the external thread rod of described straight plate both sides is contrary.
In technique scheme, described interior hexagonal counterbore faces the through hole of rear fixed plate.
The beneficial effects of the present invention is:
Present configuration is simple, easy to use, and turn driving shaft drives two external thread rods,
External thread rod top is made to be fixed in nut so that light curtain is fixing in the enclosure, rear fixed plate
Calvus is fixed in elevator door so that light curtain can fixedly secure, and ensures elevator normal safe fortune
OK.
