Description
Technical field
The utility model relates to a kind of Hanging chart stand, specifically a kind of school wall map frame of the usefulness that is used to impart knowledge to students.
Background technology
Hanging chart stand is many school teachers one of frequent teaching aids that use in teaching, and in a lot of course teachings, teacher's custom utilizes chart to show that the cooperation explanation increases teaching efficiency.Chart itself has advantages such as vision is good, price is low, easy to use, even if today that multimedia is popularized, in view of wall chart easy to use, that teaching efficiency is good is still adopted by numerous teacher.But at present the Hanging chart stand that uses is woodenly to make or simply be welded with metal mostly, the profile clumsiness, rough surface, it is big to take up room, it is very not attractive in appearance to be placed on the classroom, and arbitrarily lifting of height, is unfavorable for that the teacher gets figure, wall chart and student viewing, be difficult to see whole charts if particularly back row student wall chart is too low, influence teaching efficiency.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and providing a kind of can conveniently impart knowledge to students, and improves the school wall map frame of teaching efficiency.
The purpose of this utility model is achieved in that this school wall map frame is made up of base, standpipe, support bar, cross bar, sleeve, geometrical clamp, standpipe is vertically fixed on above the plinth, on the tube wall of the top of standpipe, be provided with fastening turn-knob, in standpipe, be with the external diameter support bar identical with the standpipe internal diameter, be provided with a plurality of annular grooves on the support bar outer wall uniformly, the support bar lower end is connected with the spring upper end of standpipe inner bottom surface, and the fastening turn-knob that is fastened in the support bar outer wall annular groove is fixed as one support bar and standpipe; Post upper is connected with cross bar, and a plurality of outer walls that are being slidingly connected on the cross bar are connected with the sleeve of geometrical clamp, all is respectively equipped with fastening bolt on each sleeve.
When specifically using the utility model,, can become flexible the distance between the fastening bolt adjustment geometrical clamp on the sleeve, clamp wall chart with geometrical clamp and get final product according to the size of wall chart; The wall chart that raises if desired can become flexible fastening turn-knob, under the elastic force effect of spring, can adjust the height of support bar easily.
Advantage of the present utility model: simple in structure, easy to use, good looking appearance, the support bar fixation, the height lifting is convenient, and helping the teacher, to get figure, wall chart and student with the aid of pictures; Distance between the geometrical clamp is arbitrarily adjustable, can make things convenient for the wall chart of the different wide cuts of teacher's clamping in the above, and convenient teaching improves teaching efficiency.
