Abstract

The utility model discloses a book case manufactured by a special process. The book case has a middle stem with bamboo-shaped bulges. The book case comprises a front cover, a back cover and the middle stem, wherein the middle stem is arc-shaped, and the bamboo-shaped bulges are formed on the middle stem. The bamboo-shaped bulges are formed by a bamboo-shaping concave-convex mould. The bamboo-shaping concave-convex mould is mainly used in the process and with a constant temperature heating system to guarantee the shaping effect, the defect in the prior manufacturing method is overcome, production efficiency and uniformity are improved, and labor intensity is reduced.

Description

A kind of book case

One, technical field

The utility model relates to a kind of book cover, especially relates to a kind of book case.

Two, background technology

Book has dividing of bound book and paperbound.Bound book just is that from the paperbound main distinction front cover of book is different.The front cover of paperbound is softcover, and the front cover of bound book is hard front cover, is called book case.The structure of book case generally comprises front cover, central diameter, back cover.

Front cover: the front that refers to book.

Central diameter: refer to book case when laid out flat, the distance between front cover and the back cover cardboard.

Back cover: the bottom surface or the quilt cover that refer to book.

In above-mentioned three key elements, wherein crucial with the comparison of central diameter.Because middle path portion is frequent force part in the whole book case, to make not in placely, the material at central diameter place occurs to wear and tear even break, and affects the use value of books.In order to address this is that, a kind of " ring " book case has appearred, and so-called " ring " book case refers to the bossed moulding as the ring shape in central diameter place of book case.The effect of " ring " makes book elegant in appearance, and the protection central diameter is not worn.The method that " ring " done in existing market has two kinds, and a kind of is to make when sticking with paste shell, and namely shell processed is extruded ring behind the sticking joint of central diameter cardboard; Another kind is to be sticked with ring behind the temporary fixed central diameter cardboard in the back of bookblock, covers with front cover again joint is extruded.No matter use any method, the book capsule that has glued ring all will carry out manual extruding with special instrument at the ring of the middle part of the side, and ring is protruded, can involucrum after the typing firmly.The method of these two kinds making " ring " because take craft as main, has that typing is poor, uniformity is short of, inefficient defective.

Three, summary of the invention

The utility model provides a kind of book case that utilizes special process to make central diameter Bamboo-shaped protuberance, and this technique mainly is to adopt ring typing concave-convex mold, is equipped with constant-temperature heating system and guarantees fixed effect.Can overcome the defective of existing production method, enhance productivity and uniformity, reduction labour intensity.The purpose of this utility model is achieved through the following technical solutions:

A kind of book case is comprised of front cover, back cover and central diameter, it is characterized in that: the Bamboo-shaped protuberance is arranged on the described central diameter.

Foregoing book case, described central diameter is arcuation.

Foregoing book case, described Bamboo-shaped protuberance forms by ring typing male and female mold.

The utility model has following good effect:

1, improved the uniformity of production efficiency and central diameter shape;

2, labour intensity and production cost have been reduced.

Four, description of drawings

The structural representation of Fig. 1: embodiment 1;

Fig. 2: ring typing male and female mold structure chart.

Five, the specific embodiment

Embodiment 1: an embodiment of the present utility model as shown in Figure 1, 2, this book case, formed by front cover 1, back cover 2 and central diameter 3, described central diameter 3 is Bamboo-shaped protuberance 4 on arcuation and its, described Bamboo-shaped protuberance 4 is to form by ring typing male and female mold 5, and the central diameter 3 of book case is consistent with the surface configuration of ring typing male and female mold 5.Central diameter 3 with book case during making places on the ring typing male and female mold 5, under external force, has occurred Bamboo-shaped protuberance 4 on the central diameter 3 of book case, adopts constant-temperature heating system to guarantee fixed effect again.Because Bamboo-shaped protuberance 4 is to form by ring typing male and female mold 5, therefore the Bamboo-shaped of a plurality of book cases protuberance 4 has a uniformity, reduce simultaneously labour intensity, improved production efficiency, adopted constant-temperature heating system can guarantee that the fixed effect of Bamboo-shaped protuberance 4 has stability.

Claims (3)

1. a book case is comprised of front cover, back cover and central diameter, it is characterized in that: the Bamboo-shaped protuberance is arranged on the described central diameter.

2. book case according to claim 1, it is characterized in that: described central diameter is arcuation.

3. book case according to claim 1 and 2 is characterized in that: described Bamboo-shaped protuberance forms by ring typing male and female mold.
