Description

A kind of bail type simple loose-leaf bookbinding folder

The utility model relate to a kind of be specifically applied to various loose-leaf files, paper bookbinding folder, refer to a kind of bail type simple loose-leaf bookbinding folder especially.

In routine work and life, various loose-leaf files or paper are bound, become a kind of requisite routine work, people are in order to finish this work easily, invent out the convenient and practical loose-leaf binder of many kinds, as various mechanical circlip type loose-leaf binders, this class loose-leaf binder has solved need of work preferably, but it is comparatively complicated to exist structure simultaneously, the deficiency that use cost is higher and service life is short, people have invented some more simple loose-leaf binders again for this reason, " plastics loose-leaf binder " as China Patent No. 88207222 indications, provided the very simple and lower loose-leaf binder of use cost of a kind of structure, though solved above-mentioned deficiency preferably, but exist and use inconvenience, bookbinding deficiency such as weak effect and can't replace existing various loose-leaf binder, and the recent various retainings that emerge in large numbers time higher loose-leaf device, though the bookbinding effect is very attractive in appearance, easy to use, but has bookbinding cost height simultaneously again, inconvenient insert or subtract the deficiency of page or leaf, thereby also fail to solve effectively the deficiencies in the prior art.

The purpose of this utility model just is to provide a kind of bail type simple loose-leaf bookbinding folder, with bookbinding structure and simple bayonet lock locate mode by its unique doubling, the function of use and the advantage that have not only kept prior art preferably, also have simultaneously easy to use, be easy to insert or subtract page or leaf, bookbinding is effective, use cost is low and applied widely advantage, overcome the deficiencies in the prior art effectively.

The purpose of this utility model realizes in the following manner: a kind of bail type simple loose-leaf bookbinding folder, mainly form by upper clip, lower clamping piece and bayonet lock, it is characterized in that lower clamping piece is provided with the bayonet lock more than three or three, thereon on the intermediate plate corresponding to the position of bayonet lock, have corresponding pin hole, be carved with two folding lines between upper clip and lower clamping piece, the width between two folding lines is corresponding to the thickness that can adorn loose-leaf.

Adopt a kind of bail type simple loose-leaf bookbinding folder of the present utility model, owing to adopted the bookbinding structure and the simple bayonet lock locate mode of unique doubling, thereby the function of use and the advantage of prior art have not only been kept preferably, also have simultaneously easy to use, be easy to insert or subtract page or leaf, bookbinding is effective, use cost is low and applied widely advantage, having overcome the deficiencies in the prior art effectively, is a kind of very desirable simple loose-leaf bookbinding folder.

Description of drawings:

Fig. 1 is a kind of example structure schematic diagram of the present utility model;

Fig. 2 is a bayonet lock structural representation of the present utility model;

Fig. 3 is a pin hole schematic diagram of the present utility model.

Wherein: 1-upper clip, 2-lower clamping piece, 3-folding line, 4-bayonet lock, 5-pin hole, 6-centre mark, 7-draw-in groove, 8-bayonet lock hoop.

Below in conjunction with accompanying drawing the utility model is described in further detail.

As shown in the figure, bail type simple loose-leaf bookbinding folder of the present utility model, mainly form by upper clip (1), lower clamping piece (2) and bayonet lock (4), it is characterized in that on lower clamping piece (2), being provided with the bayonet lock (4) more than three or three, the bottom of above-mentioned bayonet lock (4) is a cylinder, its top has draw-in groove (7), and its top perimeter is smooth arc transition; In the last position of upper clip (1) corresponding to bayonet lock (4), have corresponding pin hole (5), this inner rim place, hole is provided with the bayonet lock hoop (8) corresponding to above-mentioned draw-in groove (7), offer two folding lines (3) that are used for doubling between upper clip (1) and lower clamping piece (2), the width between two folding lines (3) is corresponding to the thickness that can adorn loose-leaf; Also be provided with the centre mark (6) of location in the center of last per two bayonet locks (4) of lower clamping piece (2).In enforcement of the present utility model, the spacing between the above-mentioned bayonet lock is identical with commercially available portable puncher spacing, is that the loose-leaf of required bookbinding punches and binds so that can utilize it easily.

In use, can adopt existing commercially available portable puncher easily, the loose-leaf that will be in sheets punches, then loose-leaf is placed on the lower clamping piece of this bookbinding folder, and make bayonet lock pass loose leaf paper, then with its upper clip along the folding line doubling, make pin hole cooperate the positioning instant can with bayonet lock.
