Abstract
The utility model provides an inclined plane demonstrator used for physics teaching and relates to a physics teaching demonstrator. The inclined plane demonstrator resolves a problem of uneasy adjustment of inclined angle existing in a conventional inclined plane demonstrating device used for physics teaching. The inclined plane demonstrator used for physics teaching comprises a pedestal, a substrate, and an inclined plane plate. The substrate is connected with the pedestal while the inclined plane plate is hinged to the pedestal. The inclined plane demonstrator used for physics teaching comprises a cylinder, a first supporting seat, and a second supporting seat. The first supporting seat is mounted on the top end face of the substrate, while the second supporting seat is mounted on the bottom end face of the inclined plane plate. The cylinder is disposed between the first supporting seat and the second supporting seat. The inclined plane demonstrator used for physics teaching employs the cylinder to adjust the inclined angle of the inclined plane plate, achieving easy adjustment of the angle of the inclined plane.
Description
Technical field
The utility model relates to a kind of physical teaching demonstration device, is specifically related to a kind of physics teaching inclined plane demonstrator, belongs to teaching technique with the apparatus field.
Background technology
In existing physics teaching, need the student is demonstrated in many situations, so that better Classroom theory knowledge is combined with practice, do not demonstrate the various physical phenomenons that relevant object produces on the inclined-plane and fairly perfect demonstration teaching aid also occurs now, such as the friction force of object, movement velocity etc.Teacher is familiar with physical phenomenon more intuitively for the student when the student being carried out the inclined-plane teaching at present, generally need to the student intuitively be observed, general way is to be combined into the apparatus with demonstration inclined-plane function by seeking suitable place or seeking different teaching aids, like this in the experimental demonstration teaching process, not only needing to spend the long time seeks suitable apparatus or place, and the apparatus of this combination is because bevel angle is difficult for fixing, easily failure in presentation process, so not only affect quality of instruction, but also reduced efficiency of teaching.
The patent No. is 200920281919.7, the applying date is that the utility model patent on November 30th, 2009 discloses a kind of " inclined plane demonstrating device for physics teaching ", this device solves adopt the combination apparatus to exist bevel angle be difficult for a fixing difficult problem, but a plurality of support slots have been offered on the inclined-plane of this device, be inserted into the angle of inclination of adjusting the inclined-plane in the different support slots by support bar, so that this device exists bevel angle to be difficult for the problem of regulating.
Summary of the invention
The purpose of this utility model is to exist bevel angle to be difficult for the problem of regulating in order to solve existing inclined plane demonstrating device for physics teaching, and then a kind of physics teaching inclined plane demonstrator is provided.
The technical solution of the utility model is: physics teaching comprises pedestal, substrate and skewback with inclined plane demonstrator, and substrate is fixedly connected with pedestal, and skewback is hinged on the pedestal; Described physics teaching also comprises cylinder, the first supporting base and the second supporting base with inclined plane demonstrator, the first supporting base is installed on the upper surface of substrate, the second supporting base is installed on the lower surface of skewback, and cylinder is arranged between the first supporting base and the second supporting base.
The utility model compared with prior art has following effect: the utility model utilizes cylinder to adjust the angle of inclination of skewback, is easy to bevel angle and regulates, and has not only improved quality of instruction, has also improved efficiency of teaching.The utility model also has advantages of simple in structure, easy to use in addition.
