Pin 18.
The described bearing of handle out of my cabin 3, lock rocking arm base 16 are separately fixed on hatch door, and described handle out of my cabin 2 is by rotating shaft 1
It is rotationally connected with on handle bearing 3 out of my cabin with embedding form and the rotation of rotating shaft 1 is by lock 4 restriction, rotating shaft 1 one end and rotating shaft out of my cabin
Rocker arm 5 one end is fixed hinged, and the rotating shaft Rocker arm 5 other end is hinged with connecting rod I 6 lower end, and connecting rod I 6 upper end is hinged with rocking arm 7 one end,
Rocking arm 7 other end is hinged with connecting rod II 8 lower end, and connecting rod II 8 upper end is hinged with inner handle rocking arm 9 one end, cabin, cabin inner handle rocking arm 9
The other end is fixed hinged with cabin inner handle 10, and connecting rod III 14 lower end is also articulated to the hinge of connecting rod II 8 upper end and cabin inner handle rocking arm 9
Contact, lock rocker-arm link 13 right-hand member in connecting rod III 14 upper end and left side is jointly hinged with lock rocker arm support 15 left end, the lock on right side
Rocker-arm link 13 left end is hinged with lock rocker arm support 15, and right-hand member is hinged with right lock pin 18 left end, the water of described lock rocker arm support 15
Flat axis one end is hinged with lock rocking arm base 16, and the other end and latch mechanism support 17 are hinged and can be around central axis.
Also including power assistant spring 19, power assistant spring 19 lower end is hinged with latch mechanism support 17, upper end and lock rocker arm support 15
The linkage section of bottom is hinged, swings along with the rotation of latch mechanism support 17 and is in compressive state all the time.
Also include the handle cover 11 being fixed on hatch door, described cabin inner handle 10 through the arc opening on handle cover 11 and
Can swing in opening, described handle cover 11 be additionally provided with the swing to cabin inner handle 10 and carries out spacing limited block.Described cabin
Inner handle 10 is coordinated with the profile of tooth on cabin inner handle rocking arm 9 by the grooved on its termination, and grooved width is more than profile of tooth width, from
And cabin inner handle rocking arm 9 can be driven to rotate and have a free travel when rotating cabin inner handle 10, as shown in Figure 9.
Locking state of the present utility model as in figure 2 it is shown, released state as shown in Figure 3.
The operation principle of this utility model mechanism is as follows:
1) in cabin, realize the unblock of hatch door and lock:
Now, lock 4 is in released state out of my cabin, and the position of cabin inner handle 10 is as shown in Figure 6；
Along the pressure handle head axially outward of cabin inner handle 10, handle head inward compression, cabin inner handle 10 is up pushed away, slips over
Limited block in handle cover 11 thus cabin inner handle 10 is unlocked, now cabin inner handle 10 is in the free travel stage, such as Fig. 7 institute
Show.Continuing up to promote cabin inner handle 10, now cabin inner handle 10 can drive cabin inner handle rocking arm 9 to rotate axially outward, enters
And drivening rod II 8, connecting rod III 14 move downward, connecting rod III 14 drives lock rocker arm support 15 to rotate counterclockwise vertically, passes through
The lock rocker-arm link 13 of left and right side drives left lock pin 12 respectively, and right lock pin 18 is along the axially inward movement of lock pin, thus by hatch door
Unlock.Meanwhile, connecting rod II 8 is moved downward by rocking arm 7 drivening rod I 6, thus drive handle 2 out of my cabin around the shaft 1 axial to
Outer rotation, is in the unlocked position.Power assistant spring 19 turns from left to right and eventually points to right direction under lock rocker arm support 15 drives,
Cabin door lock mechanism is kept to be in released state, as shown in Figure 5.
Cabin inner handle 10 is down pushed away, drives cabin inner handle rocking arm 9 to rotate axially inward, and then drivening rod II 8, even
Bar III 14 moves upward, and connecting rod III 14 drives lock rocker arm support 15 to rotate clockwise vertically, by lock rocker-arm link 13 respectively
Drive left lock pin 12, right lock pin 18 along lock pin axially outward movement, thus realize hatch door and lock；Meanwhile, connecting rod II 8 passes through rocking arm
7 drivening rods I 6 move upward, drive handle 2 out of my cabin around the shaft 1 rotation axially inwards；Continue down to promote cabin inner handle
10 so that it is cabin inner handle 10 is locked by the limited block slipped in handle cover 11, thus by hatch door lock into place, handle 2 is also out of my cabin
It is in the locked position, as shown in Figure 6；Power assistant spring 19 rotates under lock rocker arm support 15 drives from right to left, eventually points to a left side
Side to, keep this cabin door lock mechanism to be in locking state, as shown in Figure 4.The now power-assisted of power assistant spring 19 and cabin inner handle
The locking composition double insurance of 10, effectively prevents hatch door to be opened accidentally.
2) realize the unblock of hatch door out of my cabin and lock:
Now, cabin inner handle 10 is in released state, as shown in Figure 7；
Opening and lock 4 out of my cabin, will pull outward by handle 2 out of my cabin, handle 2 is down transported by rotating shaft Rocker arm 5 drivening rod I 6 out of my cabin
Dynamic, and then down moved by rocking arm 7 drivening rod II 8, connecting rod II 8 drives cabin inner handle rocking arm 9 to rotate axially outward, from
And drivening rod III 14 moves downward, connecting rod III 14 drives lock rocker arm support 15 to rotate the most counterclockwise along it, by lock rocking arm
Connecting rod 13 drives left lock pin 12, the axially inward movement of right lock pin 18 respectively, thus is unlocked by hatch door.Meanwhile, cabin inner handle shakes
Arm 9 drives cabin inner handle 10 to be rotated up, and cabin inner handle 10 is in hatch door unlocked position, as shown in Figure 8.Power assistant spring 19 is at lock
Turn from left to right under rocker arm support 15 drive and eventually point to right direction, keep this cabin door lock mechanism to be in released state, such as Fig. 5
Shown in；
To push away inside by handle 2 out of my cabin, handle 2 is up moved by rotating shaft Rocker arm 5 drivening rod I 6 out of my cabin, and then by shaking
Arm 7 drivening rod II 8 up moves, and connecting rod II 8 drives cabin inner handle rocking arm 9 to rotate axially inward, thus drivening rod III
14 move upward, and connecting rod III 14 drives lock rocker arm support 15 axially to turn clockwise along it, is carried respectively by lock rocker-arm link 13
Dynamic left lock pin 12, the axially outward movement of right lock pin 18, thus hatch door is locked.Meanwhile, hands in cabin inner handle rocking arm 9 drives cabin
Handle 10 rotates down, and makes cabin inner handle 10 be in hatch door upper lock position, as shown in Figure 7.Power assistant spring 19 is at lock rocker arm support 15
Rotate from right to left under drive, eventually point to left direction, keep this cabin door lock mechanism to be in locking state, as shown in Figure 4.Lock
Determine to lock 4 out of my cabin, this cabin door lock mechanism is locked.Now the power-assisted of power assistant spring 19 and lock 4 composition double insurance out of my cabin, the most anti-
Only hatch door is opened accidentally.
