A kind of elevator cage door latch hook device, including mounting base, latch hook and extension spring, described latch hook are provided with hinge hole,
Latch hook is hinged with mounting base, and the side of hinge hole, which is provided with, carries hook-shaped side arm, and the top of opposite side is provided with major axis bearing arm, under
Side, which is provided with short axle bearing arm, major axis bearing arm and short axle bearing arm, is equipped with bearing, and the downside of short axle bearing arm is provided with caging bolt, spacing
Extension spring connecting hole is provided with by bolt；Described mounting base is provided with pivoted arm and extension spring fixed column, and pivoted arm two ends connect a left side respectively
Door knife and right door knife, are provided with extension spring between extension spring fixed column and described extension spring connecting hole, described major axis bearing arm is held with short axle
Arranged on left and right sides of the bearing respectively with right door knife on arm is tangent.
Pivoted arm limited post is provided with by pivoted arm on the mounting base, pivoted arm limited post is by limit shaft sleeve, limit shaft and six
Angle nut composition.
Described caging bolt is rubber hook bolt, is connected by stop nut with latch hook, spacing using rubber hook bolt
It is adjusted, rubber bolt need to only reverse the purpose that bolt can reach regulation latch hook, low cost, side because threaded during regulation
Convenient to operate.
Described bearing is connected by hex nut, screw with latch hook, and elastic washer, plain cushion are provided between bearing and latch hook
Circle.
Described latch hook is integral type structure, i.e., except bearing and its installed part, latch hook sheet passes through metal plate process as thin plate
Integrally formed single part, manufacture and mounting process are easy.
The utility model has significant advantage and beneficial effect compared with prior art：Bearing suits with right door knife door knife
Close and convenient adjustment, it is simple in construction, safe and reliable；Use rolling bearing, low noise, long lifespan；Use the spiral shell with Rubber end
Bolt is spacing, easy to adjust；Using new latch hook, door opening action is realized, meets new standard requirement, neither influences door opening action,
And simple in construction and practicality, it is lightweight, economize on resources；Utilize new latch hook, when the elevator is run, latch hook lockup state, gate
It can not open, security reliability is greatly improved；When elevator is in enabling area normal switch door, latch hook is lifted, and gate is normally-open
Close.
