Abstract

The utility model relates to a book rack for reading use, comprising a book supporting board, book clamps and a support frame, wherein, the top and the bottom ends of the book supporting board are respectively provided with a book clamp, and the book clamp is composed of a support abutment, a main press arm hinged with the support abutment, an auxiliary press arm hinged with the front end part of the main press arm, and a tension spring. The support frame is a bottom board which is hinged with the rear part of the bottom of the book supporting board, a support leg split into a top and a bottom parts is hinged between the outer end of the support frame and the middle upper part of the book supporting board. The utility model has the advantages of simple structure, reliable tension without rebound, convenient and laboursaving conversion of tension, powerful setting out of clamping books, thoroughly exposure of writing near to the point of a book slot, and arbitrary selection of the angle of the bookshelf. The bookshelf can be used for people to read and learn conveniently.

Description

Rack for reading book

The utility model relates to cultural goods, particularly a kind of rack for reading book.

Rack for reading book is a kind ofly to be used for folding up books, and remove from hand-held, the instrument of being convenient to read.In the prior art, rack for reading book generally is made up of three parts: i.e. book clamp, book resting plate and support.Book clamp wherein mostly is elastic force type, or friction-type, screw thread formula or the like.Their shortcoming is, what have can pine slow-witted (impersonal force control, book clamp is in unclamped state), but the folder book is unable; The folder book that has is strong, but can not stay by pine; What have can stay by pine, and the folder book is strong, but the degree of tightness conversion is wasted time and energy.And the support of rack for reading book generally also is to have only an angle.Therefore necessary improvement.

The purpose of this utility model be intended to overcome above-mentioned shortcoming of the prior art, and it is rational in infrastructure to propose a kind of book clamp, and the support angle is adjustable rack for reading book arbitrarily.

The purpose of this utility model can realize by following proposal.

Rack for reading book comprises book resting plate, book clamp and support.Respectively there is a book clamp at the two ends up and down that it is characterized in that said book resting plate, book clamp is by the bearing that is fixed on the book resting plate, the main pressure arm hinged with rear portion on the bearing, the vertical hinged secondary pressure arm of main pressure arm front end and be connected bearing with main pressure arm between the extension spring composition.Said support is a hinged base plate at the rear portion, the end of book resting plate, a hinged supporting leg that is divided into two sections that hinge is arranged at the middle part between the middle and upper part of its outer end and book resting plate.

Below in conjunction with embodiment of the present utility model and accompanying drawing, rack for reading book is described in detail.

Fig. 1 rack for reading book front view;

Fig. 2 rack for reading book side view.

The utility model rack for reading book also comprises book resting plate, book clamp and support several sections.Its book resting plate 4 respectively is fixed with a book clamp at upper/lower terminal.Book clamp is made up of bearing 5, main pressure arm 2, secondary pressure arm 1 and extension spring 6.Bearing is connected with axle 7 with the following rear portion of main pressure arm at last rear portion.The plane of main pressure arm front end is located with a hinged secondary pressure arm of bearing pin, and secondary pressure arm is the hook-shaped of symmetry.Be connected the extension spring between bearing and the main pressure arm, can make main pressure arm be pressed on the book or pine slow-witted (resting on non-compacted position).For main pressure arm can be stopped in position, also have one to open limited shoulder 3 at main pressure arm rear lower.Extension spring also can be substituted by nonmetallic elastic class pulling force thing.

The support of rack for reading book is a hinged base plate 11 at the rear portion, the end of book resting plate.It can be a triangle.A hinged supporting leg that is divided into two sections that hinge 9 is arranged at the middle part between its outer end and the book resting plate.8, the 10 usefulness hinges of supporting leg up and down of support connect, between the two by the fixing relative position of frictional force.Upper and lower supporting leg can be that a side is two, and a side is one; Also can be that both sides are one.

The utility model in use, earlier the base plate with support is opened to suitable position, at this moment the supporting leg up and down of support is by the folding stretching, extension holding state that becomes, book resting plate relies on then up and down that the frictional force between the supporting leg axial region rests on required angle.Folding up of book then is pulled upwardly with the major and minor pressure arm of hand with book clamp, and when the parallel lines of main pressure arm rotational angle and book resting plate surpassed 90 °, under the effect of extension spring, main pressure arm was to layback, and is parked in the limited shoulder place.This is that the pine of main pressure arm is slow-witted.After having turned over page, spur major and minor pressure arm downwards, secondary pressure arm just can be pressed in the two ends up and down of page tightly under the effect of extension spring.

The utility model is simple in structure, opens when it uses, and the time spent can not fold.In the use, pine stays reliably not resilience, and the degree of tightness conversion is laborsaving quick, and the folder book is open and flat strong, and the writing at close book seam place fully appears, and the bookshelf angle can be selected arbitrarily.This bookshelf will be convenient for people to study and learning greatly.

Claims

1 one kinds of rack for reading book, comprise book resting plate, book clamp and support, respectively there is a book clamp at the two ends up and down that it is characterized in that said book resting plate, book clamp is by the bearing that is fixed on the book resting plate, the main pressure arm hinged with rear portion on the bearing, the vertical hinged secondary pressure arm of main pressure arm front end and be connected bearing with main pressure arm between the extension spring composition; Said support is a hinged base plate at the rear portion, the end of book resting plate, a hinged supporting leg that is divided into two sections that hinge is arranged at the middle part between the middle and upper part of its outer end and book resting plate.

2 according to the described bookshelf of claim 1, it is characterized in that the main pressure arm rear lower of said book clamp has one to open limited shoulder.

3 according to claim 1 or 2 described bookshelves, it is characterized in that the supporting leg up and down of said support connects with hinge, between the two by the fixing relative position of frictional force.
