When dynamic certain angle, the limit shaft 83 can prevent the resetting cam 81 from being rotated further and compress the scotch 60.Pass through
The limited post 71 and limit shaft 83 can effectively limit the upper pendulum of scotch and lower swinging, to ensure to lock and unlock
The normal use of function.
Preferably, the locking spring 72 is set on limited post 71, so that 100 structure of unlocking device for locking is more
It is succinct, is conducive to reduce its volume.
In other embodiments, the limit method of other forms can also be taken to limit the amplitude of fluctuation of scotch 60
Degree, for example limited post is respectively set at scotch both ends, limit the amplitude of pendulum or the bottom on both ends.
The course of work of the utility model binder and its unlocking device for locking is as follows：
Incorporated by reference to Fig. 2, when binder original state, 60 both ends of scotch are applied by locking spring 72 and resetting cam 81 respectively
The active force added, both ends keep horizontality, and the connecting rod 41 of platen head 40 can pass through the cylinder of scotch 60 at this time
Stop hole 62.
After user starts binding instructio, motor 31 works, and drill elevating mechanism 30 executes lowering action (action A).
Drill elevating mechanism 30 moves down, and squeezing platen head 40 by power transmission spring 21 moves down, and until that will be in sheets, data compression is
Only, reset lever 50 moves downward under the drive of nut 51 ' at this time, and return pin 53 is made to be detached from the notch of resetting cam 81, stop
No longer by the upward pressure on top surface of resetting cam 81,60 one end of scotch is swung up and (is executed dynamic by 72 pressure of locking spring block 60
Make B), the cylindrical stop hole 62 of such scotch 60 will block the connecting rod 41 being connect with platen head 40, to lock platen
First 40, stably fix data of being in sheets.
Then, drill elevating mechanism 30 rises, when the drive rising predetermined altitude of reset lever 50 of fixed plate 32, specifically,
The lifting position of the process can be accurately controlled by position microswitch, at this point, the one end of scotch 60 far from connecting rod 41 is basic
Not by the upward pressure on top surface of resetting cam 81, platen head 40 is locked always.Binder drills to data of being in sheets, riveting pipe etc.
Bind operation.
It after the completion of binding operation, is controlled by chip program, motor 31 works, and driving drill elevating mechanism 30 executes rising
Action (action C), drill elevating mechanism 30 rises predetermined altitude, such as several millimeters again, and reset lever 50 is by larger at this time
Upward pulling force, by 53 top pressure resetting cam 81 of return pin around the rotation of camshaft 82 (action D), and then scotch 60 is driven to hold
E is made in action, and the one end of scotch 60 far from connecting rod 41 is rotated up, scotch 60 close to one end of connecting rod 41 it is natural around the shaft to
Until horizontal position, the connecting rod 41 being connect with platen head 40 is no longer stopped 62 clamping of cylindrical stop hole of block 60 for lower rotation,
Connecting rod 41 is released, and platen head 40 is automatic to reset upwards under the pressure effect of resetting spring 22.
It should be noted that in the present embodiment, retaining mechanism and unlocking mechanism impose backwards to scotch 60 respectively
The active force of stitching plate 11 is to lock and reset platen head, and in other embodiments, retaining mechanism and resetting-mechanism can also
The power towards stitching plate 11 is imposed to scotch 60 to realize the locking and reset of platen head, but directly drill is utilized to lift respectively
The decline and vertical motion of mechanism 30 impose the power backwards to stitching plate 11 to lock and unlock platen head to scotch 60, can make
Obtaining binder has relatively simple structure, to reduce failure rate and manufacturing cost.
In conclusion compared with the existing technology, the Advantageous of the utility model binder and its unlocking device for locking is imitated
Fruit includes but not limited to：
First, by the way that the scotch similar to lever and the trepanning on scotch is arranged, and the both ends of lever are applied respectively
Power realizes the connecting rod (the connecting rod other end is fixedly attached to platen head) for locking and unlocking and stretching into hole, improves binder and fixes platen
The stability of head prevents that opposite sliding occurs in forwarding, improves bookbinding quality and bookbinding effect；It reduces and automatically resets
Mortality, be obviously improved the batch binding efficiency of binder.
Second, distinguish applied force by the both ends to scotch and realize locking and unlocking platen head, takes full advantage of lever
Principle will lock and unlock applied power centrifugation in the both ends of lever, to borrow the existing drill lifting of binder
The action of mechanism realizes that platen head automatically resets so that binder has simple structure, reduces the generation of failure, reduces manufacture
Cost, at the same it is user-friendly.
Third, setting position-limit mechanism prevent the scotch amplitude of oscillation is excessive from causing stuck, enhance the reliability of bookbinding；Meanwhile
The function that limit and locking reinforcing are realized using only screw plus spring set of device, saves space, increases the zero of binder
Part integrated level.
4th, unlocking mechanism borrows the action that the intrinsic driving drill of binder rises, and drives rotatable resetting cam
It rotates and then compresses scotch, the connecting rod for making its release lock, contact wear is small to be not easy by compressing for resetting cam and scotch
Fatigue can extend the service life of unlocking mechanism, ensure the stability of unlocking mechanism.
Some exemplary embodiments provided by the utility model are described in detail above, for the one of this field
As technical staff have change in specific embodiments and applications based on the idea of the embodiment of the present invention
Place, in conclusion the content of the present specification should not be construed as a limitation of the present invention.
