Abstract
The utility model relates to a physical teaching blackboard device, including the blackboard body who is the rectangle structure, the slider of blackboard body both sides is located the spout of guide rail, the guide rail upper end is equipped with the leading wheel, be equipped with the drive wheel on guide rail lower extreme one side, the drive wheel is arranged with the ratchet is coaxial, the ratchet contacts with the pawl, the pawl contacts with the flexure strip that sets up on the guide rail, the hoisting rope of blackboard body upper end is walked around the leading wheel and is connected with the drive wheel. The utility model discloses during the use, when mr's height is not enough, can break the pawl into two with one's hands, through the rotate clockwise drive wheel, the hoisting rope moved round the leading wheel this moment, blackboard body high decline this moment, and it is suitable when high to reach as blackboard body, unclamps the pawl, and ratchet, pawl can keep blackboard body's stability at this moment, vice versa, the area of writing of the mr make full use of blackboard of being convenient for like this is favorable to improving teaching effects, convenient operation, the practicality is good.
Description
Technical field
The utility model relates to instructional technology field, particularly relates to a kind of physics teaching blackboard device.
Background technology
Teaching is the distinctive personnel training activity of a kind of mankind that the religion of teacher and of student form.By this activity, teacher has object, planned and organized ground guiding student actively consciously to learn and accelerates to grasp Cultural Science rudimentary knowledge and basic skills, promotes that the many-sided quality of student improves comprehensively, makes them become people required for society.
Physics and all things on earth are all reasonable, the inherent law of self-explanatory characters' thing, the reason of things, be research material (quality) structure, matter interaction and the characteristics of motion natural science, be one with experiment and be viewed as basis natural science.The reason of instruction things in scientific circles.
At present, often need at blackboard in the process of physics teaching, teacher writes on blackboard, existing blackboard is generally fixedly connected with metope, when the height that is a teacher like this is inadequate, be difficult to the write area making full use of blackboard, so just easily often wiping, occupy the class period, reduce teaching efficiency.Therefore, for solving the problem, spy provides a kind of new technical scheme.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of physics teaching blackboard device.
The utility model is achieved through the following technical solutions:
A kind of physics teaching blackboard device, comprise the blackboard body of rectangular structure, the slide block of described blackboard body both sides is positioned at the chute of guide rail, described guide rail upper end is provided with directive wheel, side, described guide rail lower end is provided with driving wheel, and described driving wheel and coaxial ratchet are arranged, described ratchet contacts with ratchet, described ratchet contacts with the flexure strip be arranged on guide rail, and the hoisting rope of described blackboard body upper end is walked around directive wheel and is connected with driving wheel.
As optimal technical scheme of the present utility model, be welded to connect between described slide block and blackboard body.
As optimal technical scheme of the present utility model, described directive wheel is fixedly connected with between guide rail.
As optimal technical scheme of the present utility model, described flexure strip is fixedly connected with between guide rail.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the utility model is by arranging directive wheel, driving wheel, ratchet and ratchet, during such use, when teacher's height is inadequate, ratchet can be broken into two with one's hands, by rotating clockwise driving wheel, now hoisting rope moves around directive wheel, now blackboard body height declines, when blackboard body reaches suitable height, unclamp ratchet, now ratchet, ratchet can keep the stability of blackboard body, vice versa, be convenient to the write area that teacher makes full use of blackboard like this, be conducive to improving teaching efficiency, easy to operate, practicality is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. blackboard body; 101. slide block; 2. guide rail; 201. chute; 3. directive wheel; 4. driving wheel; 5. ratchet; 6. ratchet; 7. flexure strip.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of physics teaching blackboard device, comprise the blackboard body 1 of rectangular structure, the slide block 101 of described blackboard body 1 both sides is positioned at the chute 201 of guide rail 2, is welded to connect between wherein said slide block 101 and blackboard body 1.Described guide rail 2 upper end is provided with directive wheel 3, and wherein said directive wheel 3 is fixedly connected with between guide rail 2.Side, described guide rail 2 lower end is provided with driving wheel 4, described driving wheel 4 is coaxially arranged with ratchet 5, described ratchet 5 contacts with ratchet 6, described ratchet 6 contacts with the flexure strip 7 be arranged on guide rail 2, wherein said flexure strip 7 is fixedly connected with between guide rail 2, and the hoisting rope of described blackboard body 1 upper end is walked around directive wheel 3 and is connected with driving wheel 4.
Its detailed description of the invention is: when using like this, when teacher's height is inadequate, ratchet 6 can be broken into two with one's hands, by rotating clockwise driving wheel 4, now hoisting rope moves around directive wheel 3, and now blackboard body 1 highly declines, when blackboard body 1 reaches suitable height, unclamp ratchet 6, now ratchet 5, ratchet 6 can keep the stability of blackboard body 1, and vice versa, be convenient to the write area that teacher makes full use of blackboard like this, be conducive to improving teaching efficiency, easy to operate, practicality is good.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
