Description
Technical field
The invention belongs to aircraft door mechanism the design of lockup equipment field, more particularly to a kind of mechanism locking device.
Background technology
Mechanism locking device is widely used in the design of hatch door mechanism, is mainly used in functional entity being locked in a certain shape
State, it is ensured that mechanism prevents misoperation in the stability of the state.When functional entity is moved, it has to be possible to smoothly unblock,
Avoid the occurrence of clamping stagnation situation.Retaining mechanism will also avoid load transmission to mechanism element as far as possible while locking function is realized
On, mechanism the excessive situation of stand under load, reducing mechanism reliability is occurred.The design of existing hatch door retaining mechanism, often relative to work(
Energy mechanism self contained function, adds the complexity of mechanism.
The content of the invention
The technical problem to be solved in the present invention is, retaining mechanism and functional entity is shared a driving, and make control
Device can realize that order is operated, it is ensured that the security of unblock.
A kind of mechanism locking device, including locking key, extension spring, clamping plate are provided for the technical solution of the present invention that solves the above problems,
The locking key is fixed on clamping plate by rotating shaft, and the locking key includes hammerlock, lock nest and cam arm on hammerlock, the lock
Arm is connected with extension spring one end, and the other end of the extension spring is fixed on clamping plate, when the locking device locking, and the extension spring is received
Tightly, the lock nest links closely lock shaft.
It is preferred that, the locking device of technical solution of the present invention also includes initiatively rocking arm, from motion rocker arm, crank, connecting rod, described
Initiatively rocking arm from the coaxial dead axle of motion rocker arm with being fixed on the clamping plate, and there is the roller of projection the initiatively rocking arm front end, described
Roller from it is described from motion rocker arm lower end notch protrusion, it is described to be connected from motion rocker arm front end with the connecting rod moving axis, the connecting rod and
The crank is connected by lock shaft, and the other end of the crank is connected on clamping plate, described to be constituted from motion rocker arm, connecting rod and crank
Four-bar mechanism, initiatively rocking arm around axle travel forward when, the roller promotes the locking key to rotate around the axis stretching extension spring, and lock nest takes off
Unlocking axle, the initiatively rocking arm, which moves forward, contacts the antetheca of the notch, promotes the four-bar mechanism motion, completes solution
Lock；When initiatively rocking arm is moved behind axial direction, the locking key loses thrust, and the hammerlock for driving the locking key is shunk in the extension spring
(101) travelled forward around axle, the lock nest fastening lock shaft completes locking.
Unique lock nest of the invention and Cam Design, can be by locking devices and work(while effectively locking is ensured
The motion synthesis of energy mechanism so that retaining mechanism and functional entity share a driving, simplify mechanism.Its control device energy
Enough realization orders are operated, it is ensured that the security of unblock.
Brief description of the drawings
Specific embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings, wherein：
Fig. 1 is locking device composition schematic diagram；
Fig. 2 is that locking device is locked motion process schematic diagram；
Fig. 3 is that locking device is locked schematic diagram；
Fig. 4 is locking device unblock schematic diagram.
Embodiment
The specific embodiment of the invention is discussed in detail below in conjunction with the accompanying drawings：
Middle clamp plate 7 of the present invention is mechanism kinematic bearing, and initiatively rocking arm 2 and the rotating shaft from motion rocker arm 3 are consolidated by a bearing pin
It is scheduled on clamping plate 7,
The principle of locking of locking device is as follows：Initiatively rocking arm 2 is rotated first, by roller 8 thereon with from motion rocker arm 3
The rear wall of notch 9 contacts to drive it to rotate so that the four-bar mechanism fortune constituted from motion rocker arm 3, connecting rod 5, crank 4, clamping plate 7
It is dynamic.In motion process, the lock shaft 11 of crank 4 contacts promotion with the hammerlock 101 of locking key 1, and it 10 is rotated around the shaft, due to extension spring 6
To the active force of hammerlock 101, the lock shaft 11 of crank 4 can be in shape of fitting all the time with the hammerlock 101 of locking key 1 in motion process
State, is shown in Fig. 2.When the lock shaft of mechanism kinematic to crank 4 enters the lock nest 102 of locking key 1, under the active force of extension spring 6, locking key 1
Lock nest 102 lock shaft 11 of crank 4 can be clasped, realize locking to four-bar mechanism, see Fig. 3.
The unblock principle of locking device is as follows：Cam arm 103 of the roller 8 first with locking key 1 first on initiatively rocking arm 2 connects
Touch, promote locking key 1 10 to rotate around the shaft, depart from the lock shaft 11 of lock nest 102 and crank 4 and unlock.Because now initiatively rocking arm 2 exists
Moved out of motion rocker arm 3 notch 9, the four-bar mechanism motion where it will not be driven, it is ensured that first unlock, figure is shown in rear motion
4.When initiatively rocking arm 2 move to when the antetheca of notch 9 of motion rocker arm 3 is contacted drive four-bar mechanism motion.Initiatively rocking arm 2
On roller 8 continue on the cam arm 103 of locking key 1 move.
