Specific embodiment:
The invention will be described in further detail with reference to the accompanying drawing.
Referring to shown in attached drawing 1~3, which is to limit voussoir 4 by fixing seat 1, connecting cylinder 2, rotary shaft 3,
Spring 5, adjusting screw rod 6, adjusting wedge 7, the composition such as mobile voussoir 8, pull rod 9.
Wherein fixing seat 1 is connect with connecting cylinder 2 by rotary shaft 3.
It is wherein opened on the downside of pull rod 9 there are two hole slot, it is in 90 degree that two holes, which intersect, and limit voussoir 4, bullet are equipped in the hole slot
Spring 5, mobile voussoir 8.9 bottom of pull rod is provided with a hole slot, which communicates with the hole slot that side is opened, and has spiral shell close to bottom hole slot
Line feature, installation and adjustment screw rod 6 in the hole slot, adjusting wedge 7.
Limit voussoir 4, which is mounted on pull rod 9, to be in contact with connecting cylinder 2 by lozenges, and the displacement of pull rod 9 is limited.
Limit voussoir 4 is in contact with connecting cylinder 2 by lozenges, provides extruding force by compressive state spring 5.
5 side of compressive state spring and limit voussoir 4 contact with each other extrudings, the other side with move voussoir 8 contact with each other it is crowded
Pressure.Mobile voussoir 8 passes through lozenges mutual extrusion with adjusting wedge 7.
Adjusting wedge 7 passes through 6 limiting displacement of adjusting screw rod.
Adjusting screw rod 6 is connected through a screw thread with pull rod 9.
Latch release mechanism working principle: being used as initial driving force by compressed spring 5, generates thrust to limit voussoir 4, makes
Voussoir 4 and 2 mutual extrusion of connecting cylinder are limited, the displacement of pull rod 9 is limited by lozenges.When the external force for acting on pull rod 9 reaches
When certain value, limit voussoir 4 is transmitted the force to, connecting cylinder 2 can generate extruding force to limit voussoir 4, when power is along 9 hole slot of pull rod
When the component in direction is greater than compression spring force, spring continuation is compressed, and limit voussoir 4 moves inwardly along 9 hole slot of pull rod, is drawn
Bar 9 starts to move upwards, and then separates with connecting cylinder 2.
Adjustable as 5 compressive state of initial driving force spring, when screw rod 6 moves upwards, band adjusting wedge 7 is moved upwards,
Adjusting wedge 7 is in contact with mobile voussoir 8 by Dovetail interface, and then is generated to mobile voussoir 8 and squeezed thrust, is reached to bullet
The amount of compression increases the state of spring 5.When otherwise screw rod 6 moves downward, reaches and state is reduced to 5 decrement of spring.
Latch release mechanism installation: first to limit voussoir 4, spring 5, adjusting screw rod 6, adjusting wedge 7, mobile voussoir 8,
Pull rod 9 is installed to designated position.The first step will limit voussoir 4, spring 5 when installation, and adjusting wedge 7 moves voussoir 8 and is mounted on drawing
In the mounting hole of bar 9, installation and adjustment screw rod 6, adjusting screw rod 6 is not installed in place.Pacify secondly by limit voussoir 4 and connecting cylinder 2
Dress.When installation, pull rod 9 is pushed up from 2 lower part of connecting cylinder, limit voussoir 4 is driven to arrive 2 restraining position of connecting cylinder, finally will
Adjusting screw rod 6 is installed to corresponding position.Last mounting-fixing base 1, connecting cylinder 2, rotary shaft 3.
