Description

Structure is through improved rotary-type calculator device

The utility model relates to the counter of being located on the ring book, and referring in particular to a kind of counter that improves after the syndeton can be at this thin counter that rotates arbitrarily on this.

The existing counter of being located on the memo pad generally all is to be installed in this front cover that approaches this or the inboard of bottom surface, must open during use, like this, should go up some information states of record by thin this sometimes, and unintentionally can be completely exposed, so this structure is convenient very inadequately in the use.

Order of the present utility model is the syndeton of improving counter, and a kind of rotatable type calculator device easy to use is provided.

The purpose of this utility model is achieved in that structure is through improved rotary-type calculator device, it comprises overcoat, loose-leaf binder, counter and connecting piece, it is characterized in that: establish a duroplasts frame on the upper left side of overcoat, respectively establish a L shaped groove in the centre of two inboards up and down at the duroplasts frame, in the middle of two side inner edges of duroplasts frame, respectively establish a semicircle small salient point; And the middle up and down corresponding position on counter is provided with the rotating shaft that embeds L shaped groove, and the corresponding position is provided with and embeds the semicircle little concave point that semicircle small salient point is used in the middle of the two side outer rims.

Above-mentioned design, counter can be packed in the duroplasts frame in view of the above and can be done 360 degree rotations, and thin basis is not opened Shi Yineng and used, and has reached safe and secret effect easy to use.

Below by drawings and Examples the utility model is described further again.

Fig. 1 the utility model is opened the main schematic perspective view of looking in back;

Fig. 2 the utility model is opened back rotary stereo synoptic diagram;

Fig. 3 is Fig. 2 A partial enlarged drawing;

Fig. 4 the utility model closes and closes the back synoptic diagram.

As Fig. 1, the utility model comprises overcoat 1, loose-leaf binder 2,counter 3, establishes aduroplasts frame 13 on the upper left side ofovercoat 1, two inboards respectively is provided with a L shapedgroove 14 at the duroplasts frame about in the of 13.

As Fig. 2,3, respectively establish a semicirclesmall salient point 15 in the middle of the two side inner edges ofduroplasts frame 13, andcounter 3 is provided with semicircle littleconcave point 32 and rotatingshaft 31.

As Fig. 4, after overcoat 1 closed and closes,counter 3 is the time spent not, can make outside itsback 33 turns to.Time spent, in it can being turned to, convenient, safety.And can adorn beautiful pattern, more exquisite.
