Teaching is wanted high quality and high efficiency and is completed above-mentioned task, a vital aspect is to follow teaching rule, handle the relation that indirect experience and direct experience combine well, the relation of impart knowledge and raising political consciousness, impart knowledge and the relation developing intellectually, and the relation of performance teacher's leading role and mobilizing students enthusiasm, consciousness.
In teaching process, due to subject difference, the thickness of books is also different; in the time that books are blocked up, teacher usually can press and puts or press gear with hand with weight after opening; to prevent the automatic closure of books or page turning, watch but be not easy to like this teacher, affect teaching efficiency.
Utility model content
The purpose of this utility model is, for above-mentioned the deficiencies in the prior art, a kind of adjustable teaching frame that improves efficiency of teaching is provided, this teaching frame can be suppressed the books that open, prevent books automatic page turning, raise the height of books simultaneously, prevented that teacher's sight from not seeing book contents from books away from excessively.
The technical scheme that the adjustable teaching frame of the utility model raising efficiency of teaching adopts is as follows:
The utility model improves the adjustable teaching frame of efficiency of teaching, comprise base, on base, be provided with support bar, on support bar, be provided with book file platform, described book file platform comprises brace table, V-arrangement spring clip plate, angular adjustment bar, bearing pin and auricle, the quantity of auricle is two, two auricles are separately positioned on the left and right sides of post upper, the quantity of brace table is two, a brace table is articulated and connected by bearing pin and an auricle, be provided with an angular adjustment bar in each brace table bottom, between two brace tables, top is provided with V-arrangement spring clip plate.
Further, described angular adjustment bar comprises sleeve pipe and intubate, and sleeve pipe upper end is fixedly connected with brace table lower surface, and intubate is inserted into inside pipe casing, in intubate, be provided with a spring button, on sleeve pipe, be provided with several locating holes for passing for spring button along casing length direction.
Further, be provided with rubber layer in base lower surface.
Further, be provided with a card article in the relative outside of each brace table.
The advantage that the utility model improves the adjustable teaching frame of efficiency of teaching is, this teaching frame can be suppressed the books that open, and prevents books automatic page turning, has raised the height of books simultaneously, prevent that teacher's sight from not seeing book contents from books away from excessively, thereby improve the quality of teaching and efficiency.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model improves the adjustable teaching frame of efficiency of teaching.
Detailed description of the invention
As shown in drawings, the utility model improves the adjustable teaching frame of efficiency of teaching, comprises base 1, is provided with support bar 2 on base 1, is provided with book file platform on support bar 2. Book file platform is used for the books of opening to clamp, and prevents the books automatic page turning after opening. Base 1 is used for support bar 2 to support, and has fixation simultaneously, can prevent that the books that clamped by book file platform from toppling over because gravity reason causes support bar. Preferably, be provided with rubber layer 11 at base 1 lower surface. Rubber layer 11 can increase the frictional force of base 1 and lectern, makes to place more stable.
Book file platform comprises brace table 3, V-arrangement spring clip plate 4, angular adjustment bar, bearing pin 5 and auricle 6, the quantity of auricle 6 is two, two auricles 6 are separately positioned on the left and right sides of post upper, the quantity of brace table 3 is two, a brace table is articulated and connected by bearing pin and an auricle, be provided with an angular adjustment bar in each brace table 3 bottoms, between two brace tables 3, top is provided with V-arrangement spring clip plate 4. Two brace tables 3 are used for respectively the books both sides under open mode to support, V-arrangement spring clip plate 4 can carry out opening and closing people operation, clamp for the books middle part under open mode, and carry out tight fit by pulling force and the books of spring, prevent that clamping is loosening. By brace table 3 and auricle are articulated and connected, can regulate the support angle of brace table, and carry out the location of angle by angular adjustment bar.
Angular adjustment bar comprises sleeve pipe 7 and intubate 8, sleeve pipe 7 upper ends are fixedly connected with brace table 3 lower surfaces, intubate 8 is inserted into sleeve pipe 7 inside, is provided with a spring button 9 in intubate 8, on sleeve pipe 7, is provided with several locating holes 10 for passing for spring button along casing length direction. Thereby by regulating the go deep into length of intubate 8 in sleeve pipe 7 to drive brace table 3 to carry out angular adjustment, when adjusting, pressing spring button is retracted into spring button in intubate 8, again the position of intubate 8 is adjusted, the spring button being positioned at after adjusting to the right place in intubate 8 stretches out from a locating hole 10 corresponding with this place, thus the positioning action of playing.
Preferably, be provided with a card article 12 in the relative outside of each brace table 3. By card article 12 is set, can take the margin of books to be inserted in card article 12, prevent that page is curling.
