Abstract
The invention discloses a kind of teaching aid compasses, with fixing leg, drawing leg, scalable graduated scale, vacuum cup, hard gland, clamping nut, navigation button, stud, as a result of fixing leg top, clamping nut is set, clamping nut and Stud connection, stud is connected by screw thread with fixing leg inwall, stud bottom connects hard gland, hard gland is connected with vacuum cup, the structure that hard gland is flushed with vacuum cup edge, scalable graduated scale rotation during mapping, hard gland is set to push vacuum cup, discharge the air in vacuum cup and compress vacuum cup edge, strengthen fixation, fixing leg is set to be come off in picture bowlder, when being completed when mapping, teaching aid compasses are allow to be easy to be removed.
Description
The technical field present invention is directly related to a kind of teaching aid compasses.
Teacher often will be in blackboard upper drawing circle, but be due to that blackboard is very smooth in middle school geometry study for background technology
Hard, the compasses of general type are not allowed to be fixed easily, and the compasses with sucker are adsorbed onto after blackboard and are not easy to lift down, and school is sent out
Compasses it is generally large, it has not been convenient to carry, made troubles to teaching.
The content of the invention
Present invention aim to provide a kind of teaching aid compasses, he effectively can help teacher to use drawing with coloured chalk on blackboard
Circle, and take very convenient.
The object of the present invention is achieved like this：A kind of teaching aid compasses, with fixing leg, drawing leg, scalable quarter
Chi, vacuum cup, hard gland, clamping nut, navigation button, stud are spent, fixing leg top sets clamping nut, clamping nut
With Stud connection, stud is connected by screw thread with fixing leg inwall, stud bottom connection hard gland, hard gland and vacuum
Sucker is connected, and hard gland is flushed with vacuum cup edge, an elongated slot slideway is set in the middle of scalable graduated scale, fixing leg passes through
Navigation button is connected with scalable graduated scale elongated slot slideway, and scalable graduated scale one end is fixedly installed drawing leg, drawing leg and set
Put ledge for chalk on blackboard.
The present invention sets clamping nut, clamping nut and Stud connection as a result of fixing leg top, and stud passes through
Screw thread is connected with fixing leg inwall, stud bottom connection hard gland, and hard gland is connected with vacuum cup, hard gland and
Vacuum cup edge is flushed, and an elongated slot slideway is set in the middle of scalable graduated scale, and fixing leg passes through navigation button and scalable scale
Chi elongated slot slideway is connected, and the structure that drawing leg, drawing leg set ledge for chalk on blackboard is fixedly installed in scalable graduated scale one end, can stretch
When contracting graduated scale rotates, fixing leg drives stud to push hard gland, hard gland pushes vacuum with rotation by screw thread
Sucker, discharges the air in vacuum cup and compresses vacuum cup edge, strengthen fixation, fixing leg is being drawn bowlder not
Preferably come off, when being completed when mapping, scalable graduated scale is rotated in the opposite direction, fixing leg passes through thread belt with rotation
Dynamic stud lifts vacuum cup, makes vacuum cup be easy to be removed.
Appended drawings 1 are the structural representations of the present invention, and the invention will be further described below in conjunction with the accompanying drawings.
Embodiment accompanying drawing shows a kind of teaching aid compasses, with fixing leg 1, drawing leg 2, scalable quarter
Chi 3, vacuum cup 4, hard gland 5, clamping nut 6, navigation button 7, stud 8 are spent, the top of fixing leg 1 sets clamping nut 6,
Clamping nut 6 is connected with stud 8, and stud 8 is connected by screw thread with the inwall of fixing leg 1, the bottom of stud 8 connection hard gland 5,
Hard gland 5 is connected with vacuum cup 4, and hard gland 5 is flushed with the edge of vacuum cup 4, and a length is set in the middle of scalable graduated scale 3
Groove slideway, fixing leg 1 is connected by navigation button 7 with the scalable elongated slot slideway of graduated scale 3, and scalable one end of graduated scale 3 is fixed
Set drawing leg 2, drawing leg 2 that ledge for chalk on blackboard is set.
Operation principle：In mapping, the length of scalable graduated scale 3 is adjusted as needed, is fixed by navigation button 7, rotation can
Flexible graduated scale 3, fixing leg 1 drives stud 8 to push hard gland 5, hard gland 5 is pushed very with rotation by screw thread
Suction disk 4, discharges the air in vacuum cup 4 and compresses the edge of vacuum cup 4, fixing leg 1 is come off in picture bowlder,
When being completed when mapping, scalable graduated scale 3 is rotated in the opposite direction, fixing leg 1 drives stud with rotation by screw thread
8 lift vacuum cup 4, and the air inlet of vacuum cup 4 is removed.
