Description

A kind of book cover

Technical field

It the utility model is related to a kind of study article, and in particular to a kind of book cover.

Background technology

Books and homework book are wrapped up commonly using book cover, are avoided for protection books or homework book, students in middle and primary schools Crimping or breakage occur for books and homework book.For convenience of parcel, there is the book cover by cutting and impression is handled in the market, But it has been observed that easily there is wrapping up not tight, front cover and is easy to abjection, cover because of Product Design Problems in existing book cover product The problem of deforming bulge.In order to solve the problems, such as that parcel is not tight, portioned product is fixed using double faced adhesive tape etc., but using two-sided Glue be easy to cause the problem of product cannot be reused or be unable to unloading, its use still has inconvenience.

Utility model content

The purpose of this utility model is that in view of the problems of the existing technology, there is provided one kind cladding is firm and attractive and durable Book cover.

For this reason, the utility model adopts the following technical solution：

A kind of book cover, including two interconnections and symmetrical cover face, the top margin in the cover face and base difference Equipped with the first folding part, the junction in the cover face and the first folding part is equipped with prefabricated profiled first broken line, the cover The outer side edges in face are equipped with the second folding part, and cover face and the junction of the second folding part are equipped with prefabricated profiled second broken line；Institute Two vertex for stating the second folding part side are respectively equipped with fastener, and the fastener is by the top of the second folding part outer side edges Angle is formed after cropped, and first folding part is equipped with the opening being adapted with fastener.

Further, the fastener is to cut off a triangle respectively on its both sides by the apex angle of the second folding part side Formed after notch.

Further, the angle on the inside of the triangular gap is 5-20 °.

Further, the top margin of second folding part and base tilt slightly inwards compared with the first broken line.

Further, the opening on first folding part and the angle on cover face top margin or base are 30-60 °.

Further, spine portion is equipped between the two covers face.

Further, the junction in the spine portion and cover face is equipped with prefabricated profiled third fold line.

Further, the inner side edge of first folding part is arc-shaped.

Further, the outer side edges of first folding part tilt slightly inwards compared with the second broken line.

Further, the outer layer in one of cover face is printed with Periodical front cover information.

The beneficial effects of the utility model are：Coat compact, the front cover of books or homework book is not easy, and cover will not Appearance is slided and shifted, and covered effect is good；The indeformable not bulge of cover, will not cause cover backfin or damage during flipbook It is bad；Fastener is not easy to deviate from after the first folding part opening is inserted into, and locking consolidates；, can without using the bonding glue such as double faced adhesive tape Realize the reuse of product and removing for cover can be facilitated；The design of arc-shaped side edges is not only beautiful, but also during flipbook not It is easy to cause the scuffing of finger；Overall structure is simple and practical, is extremely suitable for students in middle and primary schools' use.

Fig. 3 is I partial enlarged view in Fig. 1；

Fig. 4 is the usage state diagram of the utility model；

In figure, 1- covers face, 2- spines portion, the first folding parts of 3-, the first broken lines of 4-, the second folding parts of 5-, the second foldings of 6- Line, 7- fasteners, 8- openings, 9- triangular gaps, 10- third fold lines, 11- books.

Embodiment

As shown in Figs. 1-3, a kind of book cover, including two interconnections and symmetrical cover face 1, the top margin in cover face 1 The first folding part 3 is respectively equipped with base, the junction of 1 and first folding part 3 of cover face is equipped with prefabricated profiled first broken line 4, the outer side edges in cover face 1 are equipped with the second folding part 5, and the junction of 1 and second folding part 5 of cover face is equipped with prefabricated profiled the Two broken lines 6；Two vertex of 5 side of the second folding part are respectively equipped with fastener 7, and fastener 7 is by the outside of the second folding part 5 The apex angle on side is formed after cropped, and the first folding part 3 is equipped with the opening 8 being adapted with fastener 7.Specifically, fastener 7 is Formed after cutting off a triangular gap 9 respectively on its both sides by the apex angle of 5 side of the second folding part.As shown in figure 3, triangle The angle of the included angle A of the inner side of v notch v 9 is 5-20 °, preferably 10 °；Angle of the outside of triangular gap 9 close to the second broken line 6 For 90 °.

To prevent that the outer edge of the first folding part 3 and the second folding part 5 is bad by folding during cladding, the first folding part 3 Outer side edges tilt slightly inwards compared with the second broken line 6, the top margin of the second folding part 5 and base compared with the first broken line 4 slightly inwards Tilt.Opening 8 and the angle on 1 top margin of cover face or base on first folding part 3 are 30-60 °, preferably 45 °；And opening 8 Length be slightly larger than fastener 7 width, to facilitate the insertion of fastener 7.Spine portion 2, spine are additionally provided between two cover faces 1 Portion 2 and the junction in cover face 1 are equipped with prefabricated profiled third fold line 10.To prevent during flipbook finger to scratch and playing U.S. Sight acts on, and the inner side edge of the first folding part 3 is arc-shaped, and the inner side edge of the first folding part 3 is set close to spine portion 2.Such as Fig. 1 Shown in 2, the outer layer of the book cover is identical with the structure of internal layer, and difference is, the outer layer in one of cover face is also Periodical front cover information is printed with, the identification of books can be facilitated and beautiful effect can be reached.

As shown in figure 4, in use, books 11 are positioned on cover face 1, respectively will along the first broken line 4 and the second broken line 6 First folding part 3 and the second folding part 5 inwardly fold into, and the second folding part 5 is covered in the top of the first folding part 1.Then will Fastener 7 is inserted into the opening 8 on the first folding part 3（See Fig. 4 dotted portions）, due to base and the first broken line 4 of fastener 7 It is adapted and fastener 7 has the small design feature in the big the inner in outer end, so that fastener 7 is not easy to deviate from from opening 8.

Compared to similar-type products, the utility model cladding is compact, and cover is not easy to slide and shifts, and without using bonding Glue, it is simple and practical in structure, it is firm durable, it is extremely suitable for students in middle and primary schools' use.
