Description

The moving plate locking mechanism of punching-binding machine of document

It is mechanical with the bookbinding punching that the utility model relates to office, more specifically refers to a kind of moving plate locking mechanism of punching-binding machine of document.

Punching-binding machine of document is a kind of common instrument in modern office, in utilizing punching-binding machine of document punching binding process, during with bookbinding glue ring bookbinding paper document, please earlier referring to Fig. 1, along with the downward pressing of handle 1, handle 1 drives moving plate 2 move left and right, bookbinding glue ring (the glue ring is not shown in the diagram) is opened, the paper that will own beat behind the bookbinding hole this moment is inserted in the glue ring, treat openhanded open handle 1 after, because the effect of the spring 3 that links to each other with handle 1, handle 1 resets, and moving plate 2 also returns to original state.Obviously, the shortcoming that this perforating binding machine exists is, in the process that handle 1 presses down, the operator makes the hand of handle 1 downward pressing can not leave handle 1, if leave handle 1, then handle 1 will reset, moving plate 2 also resets thereupon, and open bookbinding glue ring also can be closed simultaneously.Therefore, use the operator of this perforating binding machine must treat that the paper document bookbinding could release handle after finishing, that is to say that operator's hand can not leave handle, otherwise do not wait binding papers intact, bookbinding glue ring is just closed, justs think, if the operator is in forwarding, having phone to connect or being in a hurry needs to handle, then the work of binding half can only be stopped, behind pending the finishing, restart stapling operation again.This perforating binding machine can not adapt to the fast pace of current office, high efficiency requirement, and very inconvenience operates also.

For this reason, the purpose of this utility model is the shortcoming that exists in the above-mentioned perforating binding machine, proposes a kind of moving plate locking mechanism of punching-binding machine of document, and after perforating binding machine uses this mechanism, it will be more flexible using.

To achieve these goals, the utility model adopts following technical scheme: the moving plate locking mechanism of this document perforating binding machine comprises rise lock, a spanner, a back-moving spring, the said lock that rises is to be hubbed at a bend piece that is fixed on the pivot of binder frame, the end face of one end is the arc surface of evagination, the medial surface of end face lower end is the arc surface of indent, the other end and back-moving spring join, and offer a groove in the inboard, middle part of the lock that rises; Described spanner is hubbed at one and is fixed on another pivot of binder frame, and spanner top is that straight portion, bottom are circle portion, and circle portion is provided with a tenon.

Because the moving plate locking mechanism of the utility model is made of a rise lock, a spanner, a back-moving spring, the said lock that rises is to be hubbed at a bend piece that is fixed on the pivot of binder frame, the end face of one end is the arc surface of evagination, the medial surface of end face lower end is the arc surface of indent, the other end and back-moving spring join, and offer a groove in the inboard, middle part of the lock that rises; Described spanner is hubbed at one and is fixed on another pivot of binder frame, and spanner top is that straight portion, bottom are circle portion, and circle portion is provided with a tenon.This mechanism places the moving plate below of perforating binding machine, the end face and the moving plate bottom surface certain clearance of lock keep rising when non-locking, when pulling spanner, tenon on the spanner arc sections breaks away from the inboard groove in lock middle part that rises, owing to strain the effect of tension spring, the lock end face that rises pushes up mutually with the lower surface of moving plate, when release handle simultaneously, moving plate can travelling backwards, thereby has just guaranteed that bookbinding glue ring is no longer closed yet.Therefore, in forwarding, in the time of will interrupting the situation of bound document as if appearance, operator's suspense file bookbinding at leisure, and then continue bookbinding, after perforating binding machine uses this mechanism, use more flexible.

Below in conjunction with drawings and Examples, the utility model is done one explains:

Fig. 1 is the motor-driven plate action of an existing punching binding schematic diagram.

Fig. 2 is a locking mechanism structural representation of the present utility model.

Fig. 2 is a locking mechanism operating state schematic diagram of the present utility model.

See also shown in Figure 2, moving plate locking mechanism of the present utility model comprises rise lock 4, a spanner 5, a back-moving spring 6, the said lock 4 of rising is for being hubbed at a bend piece that is fixed on the pivot 41 of binder frame, the end face of one end is the arc surface 42 of evagination, the medial surface of end face lower end is the arc surface 43 of indent, the other end 44 joins with back-moving spring 6, and the other end of back-moving spring 6 is fixed in the binder frame, offers a groove 45 in the inboard, middle part of the lock 4 that rises.

Described spanner 5 is hubbed at one and is fixed on another pivot 51 of binder frame, spanner top is that straight portion 52, bottom are circle portion 53, circle portion 53 is provided with a tenon 54, this tenon 54 can enter in the inboard groove 45 in the lock middle part of rising, and the curvature of the interior concaved circular cambered surface 43 of the described lock 4 end face lower end medial surfaces that rise is identical with the curvature of the round portion 53 of described spanner 5 bottoms.

Locking mechanism of the present utility model when non-locking, the end face 42 and moving plate 2 bottom surface certain clearance of the lock 4 that keeps rising, the moving plate of the perforating binding machine of this moment is as original puncher.When needs lock, when pulling spanner 5 (among the figure shown in the arrow), tenon 54 on the spanner arc sections breaks away from the inboard groove 45 (please cooperate referring to Fig. 3) in lock middle part that rises, because the effect of tension tension spring 6, the lock end face 42 that rises pushes up mutually with the lower surface of moving plate 2, so, when release handle 1 (among Fig. 2 and Fig. 3 show), moving plate 2 can travelling backwards, and because the round portion 53 of spanner 5 is fastened on the interior recess of lock 4 inboards of rising, spanner 5 also rests on this position.The fixing of moving plate 2 also just guaranteed that bookbinding glue ring again can be not closed because of release handle 1.If when needing to continue operation, as long as after pulling spanner 5 and tenon 54 on its arc sections being entered rise in the inboard groove 45 in lock middle part, perforating binding machine then can be proceeded punching binding again, and this mechanism arrangement is behind perforating binding machine, for operator's use provides great convenience.
