Compared with the prior art, the portable book placement device has the advantages of reasonable design, simple structure and convenient using and the like, can achieve the effect not be achieved by a common sucker, is easy for smooth teaching, and effectively improves teaching efficiency and learning efficiency of students.
Description
Technical field
The utility model relates to a kind of teaching tool, a kind of specifically portable books apparatus for placing simple in structure.
Background technology
In the present school instruction, the teacher is at the enterprising andante book of blackboard be absolutely necessary content, especially math teacher, and often having a large amount of mathematical formulaes, stem, legend need write on blackboard or draw.At this moment the mathematics teacher is general selects one to hand book writing on the blackboard on the other hand; So just cause the teacher when writing or chart, hand can not be used flexibly, especially when teaching aids such as ruler, compasses all will use; This just brings very burden to teaching; Because the teaching aid that uses is more, just cause the efficient of writing lower easily simultaneously, teaching is caused certain influence.
Summary of the invention
The technical assignment of the utility model is the deficiency that solves prior art, and a kind of portable books apparatus for placing simple in structure is provided.
The technical scheme of the utility model realizes by following mode; This a kind of portable books apparatus for placing; Its structure comprises book supporting board, and said book supporting board is connected with a piston cylinder through upper connecting rod, lower connecting rod, is provided with piston in this piston cylinder; Piston passes this piston cylinder and at piston cylinder outer setting one pressure handle, the piston between this pressure handle and the piston cylinder is provided with back-moving spring.
The nozzle of said piston cylinder is a horn mouth.
Connect fixing through the universal ball that is connected between said book supporting board and upper connecting rod, book supporting board and the lower connecting rod.
Said upper connecting rod is an expansion link, and lower connecting rod is a fixed bar.
Overhanging vertical fixing one base in said book supporting board bottom.
The beneficial effect that the utility model is compared with prior art produced is:
Characteristics such as that a kind of portable books apparatus for placing of the utility model has is simple in structure, easy to use, be skillfully constructed; Its structure makes book supporting board be easy to be fixed on the planes such as blackboard or wall; Be easy to carry, realized the common sucker effect that is beyond one's reach, what be easy to impart knowledge to students carries out smoothly; Effectively improve efficiency of teaching and Students'learning efficient, have good value for applications.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Mark in the accompanying drawing is represented respectively:
1, horn mouth, 2, piston cylinder, 3, piston, 4, upper connecting rod, 5, universal connection ball, 6, lower connecting rod, 7, book supporting board, 8, base, 9, pressure handle, 10, back-moving spring.
The specific embodiment
Below in conjunction with accompanying drawing a kind of portable books apparatus for placing of the utility model is done following the detailed description.
Shown in accompanying drawing 1; This a kind of portable books apparatus for placing; Its structure comprises book supporting board 7, and said book supporting board 7 is connected with a piston cylinder 2 through upper connecting rod 4, lower connecting rod 6, is connected ball 5 connections and fixes through universal between book supporting board 7 and upper connecting rod 4, book supporting board 7 and the lower connecting rod 6; Wherein upper connecting rod 4 is an expansion link, and lower connecting rod 6 is a fixed bar; Be provided with piston 3 in the above-mentioned piston cylinder 2; This piston cylinder 2 passes and at piston cylinder 2 outer setting one pressure handle 9 in the bar portion of piston 3; Pressure handle 9 is arranged between upper connecting rod 4 and the lower connecting rod 6, and the piston 3 between said pressure handle 9 and the piston cylinder 2 is provided with back-moving spring 10, and the nozzle of above-mentioned piston cylinder 2 is a horn mouth 1; The fixing base 8 that also stretches out in book supporting board 7 bottoms, this base 8 and book supporting board 7 vertical settings.
Upper connecting rod 4, lower connecting rod 6 are welded on the piston cylinder 2.
Can earlier pressure handle be pressed for 9 times during use; Selection needs fixing blackboard or other planes then; At this moment piston 3 will slowly recover under the effect of back-moving spring 10, makes and produces negative pressure in the piston cylinder 2, and piston cylinder 2 is firmly fixing; At this moment the length that only needs to regulate upper connecting rod 4 is books fixedly, and whole use is flexible.
Claims (5)
