Abstract
The utility model provides a multifunctional drawing rule and belongs to the technical field of teaching aids. The multifunctional drawing rule adopts the following structure that a left sliding sleeve and a right sliding sleeve are sleeved on a rule body of a straight rule; the left sliding sleeve and the right sliding sleeve are connected with the straight rule in a sliding mode; fastening bolts are respectively arranged on the left sliding sleeve and the right sliding sleeve and are screwed with and abutted against the rule surface of the straight rule; a left bunch seat is arranged on the top surface of the left sliding sleeve; a left sucker is arranged on the bottom surface of the left sliding sleeve; a right bunch seat is arranged on the top surface of the right sliding sleeve; a right sucker is arranged on the bottom surface of the right sliding sleeve; a soft rope is connected between the left bunch seat and the right bunch seat; a chalk tube is in connection on the soft rope in a penetrating manner; and a pressing rope spring fastener is arranged on the chalk tube. According to the multifunctional drawing rule, the left and the right suckers are simultaneously adsorbed on a blackboard by utilizing the sliding connection of the left and the right sliding sleeves; the straight rule can be firmly fixed; the functions of the multifunctional drawing rule can be expanded in various aspects; and the multifunctional drawing rule is simple and convenient and integrates multiple functions into one whole body.
Description
Technical field
The utility model relates to the teaching equipment technical field, specifically a kind of multifunctional drawing ruler.
Background technology
General, in the teaching of blackboard writing on the blackboard, draw ellipse, all be to utilize compasses mostly, on two pin of compasses, fasten a rope; Outwards support rope on one side with chalk and on blackboard, stay person's handwriting on one side, promptly get the first half of an ellipse, do same action in two underfooting sides of compasses again; Oval the latter half, so oval drafting is very loaded down with trivial details, and teacher's dynamics is required also than higher; Accidentally then can depart from by person's handwriting, or chalk fractures, bring negative influence to teaching.
Summary of the invention
The technical assignment of the utility model is the deficiency that solves prior art, and a kind of multifunctional drawing ruler is provided.
The technical scheme of the utility model realizes by following mode, this multifunctional drawing ruler, and its structure is on the blade of ruler, to be socketed with left sliding sleeve and right sliding sleeve; Left side sliding sleeve, right sliding sleeve and ruler are slidingly connected; Be respectively arranged with fastening bolt and the straight related scale apical grafting of screwing on a left side sliding sleeve and the right sliding sleeve, left sliding sleeve end face is provided with left wire mount, and left sliding sleeve bottom surface is provided with left sucker; Right sliding sleeve end face is provided with right wire mount; Right sliding sleeve bottom surface is provided with right sucker, is connected with tightrope between left wire mount and the right wire mount, and cross-under has the chalk pipe on the tightrope.
The chalk pipe is provided with presses the rope snak link.
The beneficial effect that the utility model is compared with prior art produced is:
This multifunctional drawing ruler utilizes being slidingly connected of left and right sliding sleeve, is adsorbed on left and right sucker on the blackboard simultaneously, can fixedly secure ruler, when avoiding singlehanded fixedly ruler because the phenomenon that the strength of style of writing is rotated ruler causes the picture straight line to be failed; And ruler can press the rope snak link that the chalk pipe is drawn ellipse on blackboard through pressing, when the needs draw circles after being adsorbed on the blackboard; Only need down, singly be adsorbed on the blackboard through chalk pipe draw circles, need not to push under the situation of pressing the snak link of restricting with a sliding sleeve with one of them sliding sleeve dismounting; Press the fixedly position of chalk pipe on tightrope of rope snak link, to guarantee that radius is constant, its function can many-sidedly be expanded; Simple and convenient, one-object-many-purposes.
This multifunctional drawing ruler is reasonable in design, simple in structure, safe and reliable, easy to use, be easy to safeguard, has good value for applications.
