Description

A kind of wedge buckle bookshelf and preparation method thereof

Technical field

The present invention relates to bookshelf technical field, more particularly to a kind of wedge buckle bookshelf and preparation method thereof.

Background technology

Books are indispensable parts in one family, and bookshelf is one of main furniture in the furniture of study, i.e., special For depositing the shelf of the books and other things concerned with books such as books, newpapers and periodicals, magazine.Books, which are thrown out without care, to be left about, and life can be allowed to become all confused, and this When, if bookshelf, whole books are organized in inside bookshelf, allows life to become clean quickly and understands.

Particularly with for student, it is necessary to bookshelf is classified to the books of study, it is easy-to-look-up, but traditional book Frame is generally fixed, and space-consuming is big, although and small-sized bookshelf is read at any time for people and study provide conveniently, It is that its general layout is relatively more fixed, it is impossible to meet the needs that student uses.

Existing bookshelf is mostly layer structure, and books can be placed in each layer, but on the shelf layer storage books when, Keeper is generally required by ladder in order to which books are put onto upper strata laminate, and its is troublesome in poeration, and ladder presence skews Possibility, potential safety hazard be present, and reader when choosing books because the position of upper strata books is higher, be not easy to read Person consults, and is equally stored inconveniently.In addition existing bookshelf is mostly that framework is made from timber, then is covered with three conjunctions above it The sheet material such as plate or plank and be made, its manufacturing cost is higher, and profile is big and heavy, mobile inconvenient；Also it is to use to have some bookshelves Plastics or metal are made, but its processing cost is higher, is unsuitable for popularization and application.

The bookshelf of traditional type is typically placed in parallel along a face wall, for the less family in part room, is taken excessive Space, the remaining space in room may be caused smaller, the books limited amount of placement, for the more family of books Speech, bookcase revolving can save space, have good storage to act on to books, and handsome in appearance.

C, wedge buckle bookshelf assembles：Several bullets that three up-to-standard bookshelves, the step B that step A is obtained are obtained Property keeper, three sets of bearing assemblies, U-bracket, several locating rods and base carry out assembling fixation, form wedge buckle book Frame.

One or more technical schemes provided by the invention, have at least the following technical effects or advantages：

As a result of a kind of wedge buckle bookshelf, including：Vertical rotating bookshelf, bottom bookcase revolving, lift supporting rod with And base, the vertical rotating bookshelf includes anterior vertical rotating bookshelf and rear portion vertical rotating bookshelf, in anterior vertical rotating It has been stamped and formed out the raised neck of 3-5 groups on bookshelf, rear portion vertical rotating bookshelf and bottom bookcase revolving, every group of projection neck Quantity is 3；The wedge buckle bookshelf also includes Mobile books frame, and swivel plate is hinged with the side of the Mobile books frame, described 3 wedge buckles are evenly arranged with the outside of swivel plate, 3 raised necks of 3 wedge buckles and one group of projection neck coordinate, so that Enable what Mobile books frame dismantled to be arranged on bookcase revolving.It is described fixed and the wedge buckle bookshelf also includes detent mechanism Position mechanism includes bottom rotary positioning mechanism, anterior rotary positioning mechanism and rear portion rotary positioning mechanism.

So that bookshelf becomes three-dimensional, it can be stored in multiple directions and compile books, fully save space, and height can Adjustment so that different crowd is suitable for using.

Comprise the following steps as a result of a kind of rotary preparation method：

1）Uncoiling feeding；

2）Rush technology hole；

3）It is punched profile；

4）Rush positioning round orifice；

5）Rush central shaft installing hole；

6）Stamped bumps neck；

7）Blanking；

Bookshelf is produced in enormous quantities in the same progressive die, substantially increases production efficiency, and bookshelf uses Stainless steel high intensity band punch forming, the mechanical strength of bookshelf is substantially increased, because the metallic luster of stainless steel causes book Frame is attractive in appearance and gets well cleaning, while the height of contour of bookshelf is symmetrical, very attractive in appearance.Simultaneously as employ with flexibly positioned The detent mechanism of part so that bookshelf can be positioned easily when rotated, and due to being provided with the raised neck of 3-5 groups on bookshelf, Allow to be hinged 3-5 book frame, be easy to the classification storage of books, and due to being hinged with rotation on the side of Mobile books frame Plate, on the outside of swivel plate on be evenly arranged with 3 wedge buckles, 3 raised necks cooperations of 3 wedge buckles and one group of projection neck, So that being arranged on bookcase revolving of can dismantling of Mobile books frame, and so that when rotated, book frame can be kept bookshelf all the time With plane-parallel, it is unlikely to so that books are trickled down.

Solve in the prior art the technology that bookshelf mechanical strength is not high, space availability ratio is not high and makes complexity to ask Topic, realizes that the high mechanical strength of wedge buckle bookshelf, space availability ratio be high, book frame is changed convenient and makes simple technology effect Fruit.
