Abstract
The utility model relates to the teaching support that a kind of blackboard is used, comprise blackboard, fixed head, described fixed head is connected with body of wall by a plurality of set bolts, described fixed head is provided with the first rotating sphere, the outside of described the first rotating sphere is provided with the first rotation ball cover, the described first outside of rotating ball cover is provided with first rotating arm, one end of described first rotating arm is provided with the second rotating sphere, the outside of described the second rotating sphere is provided with the second rotation ball cover, the described second outside of rotating ball cover is provided with the second turning arm, one end of described the second turning arm is connected with blackboard, and be provided with the hydraulic stem being arranged symmetrically with between described the second turning arm and blackboard.The utility model is simple in structure, reasonable in design, the utility model can be realized the left and right angular adjustment of blackboard, and highly regulates up and down, can make the student of front-seat both sides, classroom and rear row's student can clearly see the content that on blackboard, teacher writes, facilitate student's study.
Description
Technical field
the utility model relates to field of Educational Technology, relates in particular to the teaching support that a kind of blackboard is used.
Background technology
blackboard not refers in particular to the plate face of black, in traditional sense, say it be one can repeated writing plane, plate face is hard, is used for teaching.With plank or ground glass etc., make, can write in the above with chalk, current blackboard is to be all directly fixed on body of wall, there is like this shortcoming, be sitting in the content of courses that the student of front-seat both sides, classroom writes due to the reflective teacher who does not see on blackboard, the suspension height of blackboard is fixed simultaneously, is sitting in the content of courses that the student who arranges behind classroom is not easy to see blackboard downside, so just student's study has been caused to inconvenience.Therefore,, for addressing the above problem, spy provides a kind of new technical scheme.
Utility model content
the purpose of this utility model is in order to overcome the deficiencies in the prior art, the teaching support that provides a kind of blackboard to use.
the utility model is to be achieved through the following technical solutions:
the teaching support that a kind of blackboard is used, comprise blackboard, fixed head, described fixed head is connected with body of wall by a plurality of set bolts, described fixed head is provided with the first rotating sphere, the outside of described the first rotating sphere is provided with the first rotation ball cover, the described first outside of rotating ball cover is provided with first rotating arm, one end of described first rotating arm is provided with the second rotating sphere, the outside of described the second rotating sphere is provided with the second rotation ball cover, the described second outside of rotating ball cover is provided with the second turning arm, one end of described the second turning arm is connected with blackboard, and be provided with the hydraulic stem being arranged symmetrically with between described the second turning arm and blackboard.
as preferably, described first rotating arm and first rotates ball cover and is fixedly connected with, and described the second turning arm is fixedly connected with the second rotation ball cover.
as preferably, the length of described first rotating arm is greater than the second turning arm.
as preferably, described hydraulic stem and the second turning arm, blackboard are hinged.
compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, the utility model can be realized the left and right angular adjustment of blackboard, and highly regulate up and down, can make the student of front-seat both sides, classroom and rear row's student can clearly see the content that on blackboard, teacher writes, facilitate student's study.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
in figure: 1. blackboard; 2. fixed head; 3. set bolt; 4. the first rotating sphere; 5. first rotate ball cover; 6. first rotating arm; 7. the second rotating sphere; 8. second rotate ball cover; 9. the second turning arm; 10. hydraulic stem.
The specific embodiment
in order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
refer to Fig. 1, the teaching support that a kind of blackboard is used, comprise blackboard 1, fixed head 2, described fixed head 2 is connected with body of wall by a plurality of set bolts 3, described fixed head 2 is provided with the first rotating sphere 4, the outside of described the first rotating sphere 4 is provided with the first rotation ball cover 5, the described first outside of rotating ball cover 5 is provided with first rotating arm 6, first rotating arm 6 can be realized around the first rotation ball cover 5 swing of multi-angle, one end of described first rotating arm 6 is provided with the second rotating sphere 7, the outside of described the second rotating sphere 7 is provided with the second rotation ball cover 8, the described second outside of rotating ball cover 8 is provided with the second turning arm 9, the second turning arm 9 can be realized around the second rotation ball cover 8 swing of multi-angle, in actual use, the length of described first rotating arm 6 is greater than the second turning arm 9, the close body of wall of being convenient to like this blackboard 1 to try one's best folds, reduce taking of 1 pair of space of blackboard, one end of described the second turning arm 9 is connected with blackboard 1, and be provided with the hydraulic stem 10 being arranged symmetrically with between described the second turning arm 9 and blackboard 1, can realize stable support to blackboard 1.
its specific embodiment is: first fixed head 2 is fixed on body of wall by set bolt 3, and the support adjustment of at least two these supports of employing to blackboard 1, so not only can realize blackboard 1 left and right angular adjustment, the highly adjusting of adjusting and downward tilt up and down, can make the student of front-seat both sides, classroom and rear row's student can clearly see the content that on blackboard, teacher writes, facilitated student's study, when blackboard 1 is not used simultaneously, can also fold to reduce taking of space.
the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
