Position ratchet 21 is connected together with locating slot 20, and slide bar 10 passes through locating slot 20, positioning ratchet 21 and third in the process of moving
The phenomenon that unidirectional movement of slide bar 10 is realized in mutual cooperation between spring 22, and slide bar 10 is effectively avoided to fall after rise, driving machine
Handwheel 17 is installed on the side outer wall of structure 9, and is embedded with unlock at the position of 17 side of handwheel on 9 outer wall of driving mechanism
It is fixed to reach absorption with this by changing the position of unlock magnetic bar 23 to increase attraction suffered by positioning ratchet 21 for magnetic bar 23
The purpose of position ratchet 21, so that the unlock of positioning ratchet 21 and locating slot 20 is realized, to guarantee that single unit system can go on smoothly solution
Lock operation, handwheel 17 and cam 8 are rotatablely connected by shaft, and unlock magnetic bar 23 is located at the remotely located ratchet 21 1 of third spring 22
At end position.
For the ease of realizing the falling of slide bar 10, in the present embodiment, it is preferred that the first spring 6 is altogether there are two settings, and two
A first spring 6 is located at the two sides of slide bar 10.
Stabilization when in order to guarantee that attachment base 2 slides, in the present embodiment, it is preferred that longitudinal chute 11 and longitudinal sliding block 13
It is convex structure.
In order to guarantee that the locking bar 4 of 1 two sides of linkage mechanism can be locked effectively, in the present embodiment, it is preferred that horizontal concrete chute 14
Altogether there are four settings, and four horizontal concrete chutes 14 are located at the two sides of longitudinal chute 11 two-by-two for one group.
For the ease of unlocking the positioning of magnetic bar 23, in the present embodiment, it is preferred that be all provided on the two sides outer wall of unlock magnetic bar 23
It is equipped with Elastic buckle.
The working principle and process for using of the utility model: when carrying out this using novel locking, drive is rotated clockwise
9 side handwheel 17 of motivation structure, handwheel 17 are rotated by shaft band moving cam 8, and cam 8 is contacted with slide plate 7 in the course of rotation,
To push slide plate 7 to move up, and slide plate 7 pushes slide bar 10 to move up during moving up, and compresses the first of 10 two sides of slide bar
Spring 6, slide bar 10 pass through the inside of limit sleeve 5, and pass through locating slot 20, positioning ratchet 21 and third in the process of moving
The phenomenon that unidirectional movement of slide bar 10 is realized in mutual cooperation between spring 22, and slide bar 10 is effectively avoided to fall after rise, and slide bar
10 push the generation of sliding slot 11 movement along longitudinal direction of attachment base 2 inside linkage mechanism 1 in the process of moving, and attachment base 2 is in movement
During drive 12 synchronizing moving of the first mounting base so that producing relative rotation between the first mounting base 12 and connecting rod 3, and lead to
It crosses connecting rod 3 and pushes the second mounting base 16 transversely generation of sliding slot 14 transverse shifting, and the second mounting base 16 is carrying out transverse shifting
During the locking bar 4 of 1 two sides of linkage mechanism is released, to realize the locking of single unit system, and when being unlocked, need
The unlock magnetic bar 23 of 17 side of handwheel is first pushed into the inside of limit sleeve 5, to reduce unlock magnetic bar 23 and positioning ratchet 21
The distance between, pass through suction after suction increases to achieve the purpose that increase unlock magnetic bar 23 and positioning 21 attraction of ratchet indirectly
The attraction of power compresses third spring 22 so that positioning ratchet 21 is close to unlock magnetic bar 23, to realize positioning ratchet 21 and fixed
Position slot 20 between unlock, contact slide bar 10 unidirectional restriction, rotate counterclockwise handwheel 17 at this time, can by slide plate 7 with it is convex
The falling of slide bar 10 is realized in revolution between wheel 8, and the return of locking bar 4 is realized by the movement of the 1 each structure in inside of linkage mechanism,
To reach unlock operation, and the first spring 6 is also formed with certain screen resilience during slide bar 10 is fallen after rise, increases slide bar
10 during falling structure itself screen resilience, guarantee with lesser rotatory force can be realized the blocking device unlock behaviour
Make, in addition when the recovery of slide bar 10 to initial position, the return pin 18 on slide bar 10 is just moved to 21 place of positioning ratchet
At position, second spring 19 rebounds at this time, pushes positioning ratchet 21 further close to unlock magnetic bar 23, to increase third bullet
The decrement of spring 22, so that the bounce of third spring 22 increases and is more than the clamping force for unlocking Elastic buckle on magnetic bar 23, because
And the Elastic buckle unlocked on magnetic bar 23 is made to lose snap-in function under the promotion of bounce, magnetic bar 23 is unlocked at this time to be then in
Removable state, the rebound of third spring 22 is to realize the reset for unlocking magnetic bar 23, to guarantee whole after completing unlocking operation
The internal structure of body device can set back.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
