Abstract
The present invention discloses a kind of set lever mechanism of large caliber weapon, including handle, pull rod, handle jacket, positioning seat, handle head, tie down screw, positioning top, jacking block pin, fixed lever pin, positioning mandril, fixed link, return spring, reset jacking block；The present invention in limited handle jacket space by using the fixed set lever of fixed link under spring force effect；Positioning function will be realized in groove that the mandril inside locking head heads into fixed link by the jacking block in specific position, and only external force sphere of action that the groove of fixed link is pulled out to mandril, mandril can just eject jacking block, and set lever can just cancel positioning function.A kind of set lever structure of large caliber weapon of the invention is simple and convenient to operate and fixes reliably.
Description
Technical field
The present invention relates to the set levers of a kind of retaining mechanism, especially large caliber weapon.
Background technique
Conventional large caliber weapon is because entire weapon system quality is larger, in order to improve the people in daily workout and use process
Machine effect, design has retaining mechanism on height and orientation.The fixed circlip of only one installation on general retaining mechanism, warp
Long-time Reusability, circlip are easy to fail, and cause retaining mechanism that cannot be effectively fixed, often fall off in use process,
Influence the performance of weapon system.
Conventional large caliber weapon is during shooting, in order to effectively aim at and kill target, just with orientation
Retaining mechanism is opening mode, and weapon system is constantly aimed at and shot in shooting course, and retaining mechanism is in weapon system
High-frequency vibration under occur automatically lock often, cause weapon cannot flexibly and accurately run-home, bungle the chance of winning a battle.
Summary of the invention
In order to solve the problems, such as existing set lever mechanism it is daily be easy to fall off with actual combat automatically lock, the present invention provides
It is a kind of with the set lever mechanism for being reliably fixed and facilitating positioning function.
The technical solution of the present invention is as follows:
A kind of set lever mechanism, including handle 1, pull rod 2, handle jacket 3, positioning seat 4, handle head 5, tie down screw 6,
Positioning top 7 and fixed link 11；Handle 1 is fixedly connected with pull rod 2, and handle jacket 3 is fixedly connected with handle head 5；Pull rod 2 is set with
In handle jacket 3,2 front end of pull rod is connect with fixed link 11；Tie down screw 6 is provided with preformed hole, and 11 front end of fixed link is inserted in
In the preformed hole of tie down screw 6；For the suit of handle head 5 on tie down screw 6, handle head 5 can drive tie down screw 6 to rotate；Handle
Location hole is formed on first 5, positioning seat 4 is set to 6 top of tie down screw, and the location hole that handle head 5 is corresponded on positioning seat 4 is provided with
Positioning top 7, positioning 7 bottoms of top are connect by pressure spring with positioning seat 4.
The pull rod 2 be it is hollow, the middle part of pull rod 2 passes through gain 14 and is fixed on handle along gain 14, jacking block pin 8 is axially arranged with
On sleeve 3, centre is provided with return spring 12, and 12 one end of return spring is connect with fixed link 11, and the other end is connect with jacking block pin 8.
The handle head 5 location hole is equipped with slidable positioning mandril 10, positioning top 7 can will be under positioning mandril 10
End top is extremely contacted with fixed link 11；Fixed link 11 is equipped with the groove for accommodating 10 lower end of positioning mandril, and in the groove of fixed link 11
Two sides are equipped with guiding surface.
The 10 lower end section of positioning mandril is triangle, the ditch profile of fixed link 11 be it is trapezoidal, trapezoidal top can will
10 upper end of positioning mandril ejects location hole.
Set lever of the invention in limited handle jacket space by using the fixed link under spring force effect to fix
Set lever；Positioning function is realized in the groove that the mandril inside locking head is headed into fixed link by the jacking block in specific position
Can, only jacking block can just be ejected the sphere of action of the groove pull-out mandril of fixed link, mandril by external force, and set lever just can use
Disappear positioning function.Structure of the invention is simple and convenient to operate and fixes reliably.
Detailed description of the invention
Fig. 1 is the scheme of installation of set lever mechanism of the present invention；
Fig. 2 is that the set lever of set lever mechanism of the present invention installs diagrammatic cross-section.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
See Fig. 1, Fig. 2, set lever mechanism of the invention includes handle 1, pull rod 2, handle jacket 3, positioning seat 4, handle
First 5, tie down screw 6, positioning top 7, jacking block pin 8, fixed lever pin 9, positioning mandril 10, fixed link 11, return spring 12, reset top
Block 13.
7 positioning top 7, positioning top is mounted on positioning seat 4, and by ejecting outward under the action of spring force in positioning seat 4,
Positioning top 7 is pushed, should be able to be flushed with 4 outer end face of positioning seat, after release, positioning top 7 can automatic ejection.
In large caliber weapon system, handle 1 is rotated counterclockwise, drives tie down screw 6 to rotate counterclockwise, weapon can be locked
The retaining mechanism of system height or orientation；Handle 1 is rotated clockwise, drives tie down screw 6 to rotate clockwise, openable weapon system
The retaining mechanism of system height or orientation realizes the state conversion of retaining mechanism.
When need to open retaining mechanism when actual combat, handle 1 is rotated clockwise, tie down screw 6 is driven to rotate clockwise, is opened
The retaining mechanism of weapon system height or orientation, set lever are rotated to position location, and positioning mandril 10 is pushed up in positioning top 7
Enter in handle head 5, and set lever is positioned, set lever mechanism will not loosen under the high-frequency vibration of weapon system；Needing will
When retaining mechanism is locked, the preformed hole that handle 1 drives fixed link 11 to exit tie down screw 6 is pulled out；Simultaneously by positioning mandril
10 push up upwards, so that positioning top 7 is exited handle head 5, rotate counterclockwise handle 1, drive the rotation counterclockwise of tie down screw 6, locking
The retaining mechanism of weapon system height or orientation.
