Summary of the invention
Simple, time saving and energy saving, the accurate slope measuring demonstrator efficiently of a kind of structure that the purpose of this utility model is to overcome above-mentioned shortcoming and provides.
The utility model object and solve its technical problem underlying and realize by the following technical solutions:
Slope measuring demonstrator of the present utility model, comprise inclined-plane assembly, slope measuring assembly, wherein: slope measuring assembly is releasably contained in assembly top, inclined-plane, inclined-plane assembly fills casket by skewback, aobvious number plate and aobvious number plate and forms, aobvious number plate is installed on bottom skewback, skewback fills casket one end rotary type with aobvious number plate and is connected, and it is inner that aobvious number plate is placed in aobvious number plate dress casket; Slope measuring assembly comprises installs casket, protractor and swing ball, installs casket and is contained in skewback top, and protractor is loaded on by installing plate and installs casket inner tip, and swing ball is connected to protractor center by cycloid.
Above-mentioned slope measuring demonstrator, wherein: aobvious number plate dress casket top is plane.
Above-mentioned slope measuring demonstrator, wherein: aobvious number plate is provided with scale, and the side that aobvious number plate and skewback are fixed is zero groove.
Above-mentioned slope measuring demonstrator, wherein: one end that skewback is connected with installation casket is provided with fixture block.
Above-mentioned slope measuring demonstrator, wherein: protractor is provided with scale, and middle part is zero groove, and reading increases successively to both sides.
The utility model compared with the existing technology has obvious advantage and beneficial effect.From above technical scheme, in slope measuring demonstrator of the present utility model, aobvious several plate of inclined-plane assembly is installed on bottom skewback, skewback fills casket one end rotary type with aobvious number plate and is connected, it is inner that aobvious number plate is placed in aobvious number plate dress casket, is placed on surface level, dug by the other end of skewback before measuring by aobvious several plate dress casket, the plane indication angle at aobvious number plate dress casket top is the gradient on inclined-plane, simple possible; The protractor of slope measuring assembly is loaded on by installing plate installs casket inner tip, swing ball is connected to protractor center by cycloid, protractor is provided with scale, and middle part is zero groove, reading increases successively to both sides, due to gravity straight down, cycloid present position is vertical curve, be close on inclined-plane by slope measuring assembly, after swing ball is stable, the angle of cycloid indication is the gradient on this inclined-plane; When gradient measurer and incline configuration use, by corresponding geometric relationship, draw plane indication angle on aobvious several plate at aobvious number plate dress casket top, equal with cycloid angular dimension of indication on protractor, the slope measuring process on inclined-plane can be demonstrated out; One end that skewback is connected with installation casket is provided with fixture block, ensure that the stability that inclined-plane assembly is connected with slope measuring assembly.In a word, the utility model structure is simple, time saving and energy saving, accurately efficient, is applicable to promoting the use of of teaching process slope measuring.
