State is linked, the spring abrupt release elastic potential energy on strike bar drives strike bar motion to clash into the frizzen of rope brake, folder rope
Device works, and elevator stops.
Further, swivel nut is provided between the hook and body, screw is provided with swivel nut, screw one end is consolidated with body
Fixed connection, the other end makes hook to be rotated around screw through hook.
Further, the fixing point in the zip fixed plate, on hook at the mode connects for screw of the bearing of zip and hook,
Between 3 points, at an angle, optimize torque and the arm of force, the friction between zip and zip sleeve can be prevented effectively from, while
Make zip to the triggering pulling force minimum linked up with, improve sensitiveness and stability.
Further, it is described strike bar below be fixedly connected with reset lever, can external force drive reset lever, make strike bar
Reset is linked with hook.
Further, the body is U-shaped, and strike bar passes through the relative both sides of body.
Further, bearing is provided with the bearing location-plate and fixes block, guiding is played a part of to hook.
Further, by front end for the square steel and back segment push rod of cambered surface are constituted, bearing location-plate is located at square steel to the strike bar
End, on push rod, one end is offseted spring housing with square steel, and the other end is fixed with this body phase.
Compared with prior art, Advantageous Effects of the present invention are mainly reflected in：
1st, the present invention installs bearing by strike bar, hook is connected by bearing element with strike bar, hits bar
There was only force of rolling friction between hook, can be prevented effectively from different power mixes what trigger mechanism sensitiveness and stability were caused
Influence.
2nd, by setting extension spring on hook, the extension spring other end is connected the present invention with body, difference may be selected and determines power
Extension spring is fixed to hook, it is to avoid elevator rocking in self-operating itself pulls to hook, causes elevator all standing, has
Effect improves the anti-interference of trigger mechanism, while retaining sensitiveness, extension spring in addition can also be led to when hook resets with strike bar
Crossing spring force allows hook to be linked automatically with bearing.
3rd, novel in structural design of the invention, simple, has the advantages that easy to assembly.
