Abstract
The utility model relates to a stretchable multipurpose book end which comprises a rectangular standing plate, a front supporting plate and a back supporting plate. The two sides of the bottom edge of the standing plate are connected with the front supporting plate and the back supporting plate through shafts respectively, two storage grooves are formed in the front end face of the front supporting plate, an elastic rope is connected to the interior of each storage groove, and the other end of each elastic rope is connected with a right-angle hook; two elastic clamping sheets are installed on the surface of the back supporting plate side by side; limiting chucks are connected to the two longitudinal edges of the lateral plate face, facing the front supporting plate, of the standing plate through shafts respectively, one limiting chuck is of a right-angle triangular plate structure, and the other limiting chuck is of an acute-angle triangular plate structure; a transparent insertion sleeve is installed on the surface of the side, facing the back supporting plate, of the standing plate; an insertion groove is formed from the top of the standing plate downwards, a two-section type push-and-pull plate is inserted into the insertion groove, and a loosening-and-tightening rotary knob is installed at positions, corresponding to the insertion groove, of lateral faces of the standing plate. The stretchable multipurpose book end has the advantages of being exquisite in structure, convenient to use and the like.
Description
Technical field
The utility model relates to a kind of teaching aid, especially a kind of book end.
Background technology
At present, people often deposit fixedly books or data with book end in study and work.Known, book end is mainly comprised of longitudinal riser and cross-brace plate two parts, but riser and the gripper shoe of book end all adopt built-in structure now, cannot change shape, take up room larger when independently depositing book end.In addition, known book end function is too single, is only suitable for using when putting books, people, reads or listens class hour that other helps cannot be provided.
Summary of the invention
The utility model object is to provide a kind of flexible multipurpose book stand that changes volume, also can offer help when listening to the teacher reading.
For achieving the above object, adopted following technical scheme: the utility model comprises rectangular riser, front end panel and rear bearing sheet, the both sides on riser base respectively axle connect front end panel and rear bearing sheet, at the front end face of front end panel, offer two accumulator tanks, in each accumulator tank, connect stretch cord, the stretch cord other end connects right angle hook; On the surface of rear bearing sheet, two spring clips are installed side by side; Riser on two longitudinal edges of front end panel side plate face respectively axle connect spacing dop, one of them spacing dop is right angle trigonometry chip architecture, another spacing dop is acute angle triangular plate structure; Transparent sleeve is installed on the surface of rear bearing sheet one side at riser; From the top of riser, offer slot downwards, assign two-part pull plate in slot, in riser side, corresponding slot position is installed degree of tightness knob.
The course of work is roughly as follows:
During normal use, user launches front end panel, then right angle trigonometry sheet is gone between riser and front end panel, by right angle trigonometry sheet restriction riser, rotates, and just can now books be placed on front end panel to the normal function of performance book end.Read while using, user all launches front and back gripper shoe, again acute angle triangular plate is gone between riser and front end panel, riser is turned to front end panel, utilize acute angle triangular plate to make riser keep heeling condition as restriction dop, now books can be launched, books base is placed on rear bearing sheet, books are leaned against to riser surface, and then open spring clip, and utilize spring clip to push down the base of books, books are fixed, now books are oblique placement, not only keep fixing but also be convenient to user's reading or write.While using as sight protectio instrument, front end panel can be launched, right angle trigonometry sheet is gone between riser and front end panel, keeping riser is vertical state, maintenance front end panel is level, from the accumulator tank of front end panel, take out right angle hook, first riser is placed on the table over against user, again right angle hook is hung on user's table limit, loosening degree of tightness knob is adjusted pull plate again, after pull plate height is determined, the epimere plate body of pull plate is gone to level, make epimere plate body and hypomere plate body in vertical state, and epimere plate body is towards user chest, by pull plate, limit user's forward lean, avoid user's eye and desktop to cross closely and the safety that affects one's power of vision.In addition, user can just insert the card form displaying articles such as card, photograph in transparent sleeve, makes book end have aesthetic feeling and sight.
Compared with prior art, the utlity model has following advantage:
1, simple, convenient and practical, can deposit books, also can be used as oblique reading tool and use;
2, adjustable height, the bad habit while reading for limiting people, avoids eye and books or desktop excessively near;
3, there is good sight, can be used as photo frame and use.
Accompanying drawing explanation
Fig. 1 is structure diagram of the present utility model.
Drawing reference numeral: 1 is that riser, 2 is that front end panel, 3 is that rear bearing sheet, 4 is that accumulator tank, 5 is that stretch cord, 6 is that right angle hook, 7 is that spring clip, 8-1 are that right angle trigonometry sheet, 8-2 are that acute angle triangular plate, 9 is that transparent sleeve, 10 is that two-part pull plate, 11 is degree of tightness knob.
the specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
In structure diagram of the present utility model as shown in Figure 1, the utility model comprises rectangular riser 1, front end panel 2 and rear bearing sheet 3, in the both sides on riser base, difference axle connects front end panel and rear bearing sheet, at the front end face of front end panel, offer two accumulator tanks 4, in each accumulator tank, connect stretch cord 5, the stretch cord other end connects right angle hook 6; On the surface of rear bearing sheet, two spring clips 7 are installed side by side; Riser on two longitudinal edges of front end panel side plate face respectively axle connect spacing dop, one of them spacing dop is right angle trigonometry sheet 8-1 structure, another spacing dop is acute angle triangular plate 8-2 structure; Transparent sleeve 9 is installed on the surface of rear bearing sheet one side at riser; From the top of riser, offer slot downwards, assign two-part pull plate 10 in slot, in riser side, corresponding slot position is installed degree of tightness knob 11.
Above-described embodiment is described preferred embodiment of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
