Description
Technical field
The utility model relates to the technical field of schooling apparatus, especially a kind of simple mechanism for historical teaching that can CAL, be convenient to place study article.
Background technology
In the time that teacher carries out historical teaching, in the time of lectern teaching material, because the height of lectern is lower than people's height, all need to bend over, bow and see teaching material, because the lectern in school can not be adapted to the height of different people, such situation is not easy to teacher's teaching, can impact people's cervical vertebra simultaneously.
Student is in the time listening to the teacher or write, and textbook lies on desk, and due to the problem of angle, people bows to see books, and such mode also can increase the burden of cervical vertebra, watches books also very inconvenient.
Lectern, the desk of tilting are not universal, and arbitrarily adjusting angle of the desk of tilting.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem that the prior art solving in above-mentioned background technology exists, provide a kind of improved simple mechanism for historical teaching.
The utility model solves the technical scheme that its technical problem adopts: a kind of simple mechanism for historical teaching, comprise base, bracing frame, the backing plate of placing articles and helical axis, bracing frame is between base and backing plate, between described base and bracing frame, be provided with connecting rod, between bracing frame and backing plate, be provided with dwang, backing plate is set on dwang, bracing frame is made up of two gripper shoes, the end, two ends of gripper shoe respectively has a connecting hole that inserts helical axis, the termination, one end of connecting rod all has the hole corresponding with connecting hole with the end, one end of dwang, bracing frame and connecting rod, bracing frame is flexibly connected by helical axis with dwang, it is L-shaped that turnover is extended forward on the base of backing plate, form flange.
On described helical axis, be provided with the nut for fastening support frame and connecting rod, dwang.
The beneficial effects of the utility model are, of the present utility model simple in structure, easy to operate, can be according to actual conditions, backing plate is carried out to the adjusting of angle, what be convenient to teacher's historical teaching and student listens to the teacher, writes situation, designs hommization more, has alleviated the burden of cervical vertebra, practicality strengthens, the scope of application is extensive, and volume is small and exquisite, is convenient for carrying.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
In figure: 1. base, 2. bracing frame, 21. gripper shoes, 3. backing plate, 4. helical axis, 5. connecting rod, 6. dwang.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of simple mechanism for historical teaching, comprise base 1, bracing frame 2, the backing plate 3 of placing articles and helical axis 4, bracing frame 2 is between base 1 and backing plate 3, between base 1 and bracing frame 2, be provided with connecting rod 5, between bracing frame 2 and backing plate 3, be provided with dwang 6, backing plate 3 is set on dwang 6, bracing frame 2 is made up of two gripper shoes 21, the end, two ends of gripper shoe 21 respectively has a connecting hole that inserts helical axis 4, the termination, one end of connecting rod 4 all has the hole corresponding with connecting hole with the end, one end of dwang 6, bracing frame 2 and connecting rod 5, bracing frame 2 is flexibly connected by helical axis 4 with dwang 6.
On helical axis 4, be provided with the nut with connecting rod 5, dwang 6 for fastening support frame 2, adjusting after the angle of backing plate 3, fastening nut, can fix the position of dwang 6, has spacing effect.
It is L-shaped that turnover is extended forward on the base of backing plate 3, forms flange, can prevent books or other article landings.
Below use of the present utility model is further introduced:
After the utility model is placed on desk, according to actual situation, the height of for example people's height or desk and chair, unscrews nut, the angle of regulating rotary lever 6, and in the time that backing plate 3 reaches applicable position, fastening nut, fixed position.
Also angle that can regulating connecting rod 5, unscrews nut, the angle of regulating connecting rod 5, and in the time that backing plate 3 reaches applicable position, fastening nut, fixed position.
Dwang 6 can be threaded connection with backing plate 3, also can connect by the mode of other flexible connection.
The utility model is applicable to teacher's the listening to the teacher and the situation of writing of historical teaching situation, student, and is also applicable to other similar site and environment, and small volume, under varying environment, can use, and be convenient for carrying.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to claim scope.
