Description
Technical field
The utility model belongs to teaching technique with the apparatus field, is specifically related to a kind of Teaching of Economics picture device.
Background technology
Long-term giving lessons in practice; teacher draws for student in datagram process at use T-square; teacher's end product error that often can mobile ruler makes to paint is larger; and teacher needs larger space to deposit; teacher in use ruler crossbeam is easy to injure arm, and inconvenient operation of teacher use and plotting error are large.
Summary of the invention
The purpose of this utility model is: draw for student in datagram process at use T-square in order to solve teacher, teacher is without the mobile ruler datagram of can painting out, and can reduce the error of drawing and producing, teacher can rotate T-square crossbeam to prevent from injuring arm at any time, facilitate operation of teacher to use and reduce plotting error, its technical scheme is as follows:
A kind of Teaching of Economics picture device, it comprises fixing horizontal piece 1, track runner 2, movable vertical chi 3, movable switch block 4, fixing inserting column 5, flexible arm-tie 6, spring stack 7, it is characterized in that: on described fixing horizontal piece 1, top end surface middle and front top end surface middle are respectively provided with track runner 2, the inner movable vertical chi 3 that is fixedly fitted with of described track runner 2 of upper surface, track runner 2 inside of front surface are fixedly fitted with movable switch block 4, the front top end surface of described movable switch block 4 is fixedly fitted with fixing inserting column 5, and described fixing inserting column 5 penetrates described movable switch block 4 and inserts described movable vertical chi 3 inside, described fixing inserting column 5 outer tip end surface are fixedly connected with flexible arm-tie 6, the rear top end surface left and right edges of described flexible arm-tie 6 middle is respectively fixedly connected with spring stack 7, described movable switch block 4 is made up of with the traveller that after described slide plate, middle, top end surface below is fixedly connected with slide plate, described slide plate and described movable vertical chi 3 are mutually permanently connected by described traveller, described traveller overall diameter size is identical with described track runner 2 inner widths, described fixing inserting column 5 side top end surface belows contact with top end surface on described fixing horizontal piece 1, described movable vertical chi 3 sizes are identical with described track runner 2 interior size on fixing horizontal piece 1 upper surface, the described fixing rear top end surface of horizontal piece 1 is fixedly connected with several suckers.
The beneficial effects of the utility model are: draw for student in datagram process at use T-square in order to solve teacher, teacher is without the mobile ruler datagram of can painting out, and can reduce the error of drawing and producing, teacher can rotate T-square crossbeam to prevent from injuring arm at any time, facilitates operation of teacher to use and reduces plotting error.
Brief description of the drawings:
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention:
With reference to a kind of Teaching of Economics picture device described in Fig. 1, it comprises fixing horizontal piece 1, track runner 2, movable vertical chi 3, movable switch block 4, fixing inserting column 5, flexible arm-tie 6, spring stack 7, it is characterized in that: on described fixing horizontal piece 1, top end surface middle and front top end surface middle are respectively provided with track runner 2, the inner movable vertical chi 3 that is fixedly fitted with of described track runner 2 of upper surface, track runner 2 inside of front surface are fixedly fitted with movable switch block 4, the front top end surface of described movable switch block 4 is fixedly fitted with fixing inserting column 5, and described fixing inserting column 5 penetrates described movable switch block 4 and inserts described movable vertical chi 3 inside, described fixing inserting column 5 outer tip end surface are fixedly connected with flexible arm-tie 6, the rear top end surface left and right edges of described flexible arm-tie 6 middle is respectively fixedly connected with spring stack 7, described movable switch block 4 is made up of with the traveller that after described slide plate, middle, top end surface below is fixedly connected with slide plate, described slide plate and described movable vertical chi 3 are mutually permanently connected by described traveller, described traveller overall diameter size is identical with described track runner 2 inner widths, described fixing inserting column 5 side top end surface belows contact with top end surface on described fixing horizontal piece 1, described movable vertical chi 3 sizes are identical with described track runner 2 interior size on fixing horizontal piece 1 upper surface, the described fixing rear top end surface of horizontal piece 1 is fixedly connected with several suckers.
When use, first pull flexible arm-tie 6 that fixing inserting column 5 is pulled out in movable vertical chi 3, then rotating flexible arm-tie 6 makes rail slider 4 drive movable vertical chi 3 to rotate, movable vertical chi 3 produces in track runner 2 simultaneously, then unclamping flexible arm-tie 6 makes spring stack 7 arm-tie 6 that will stretch retract reset condition, fix inserting column 5 inserts in movable vertical chi 3 simultaneously, finally the sucker at fixing horizontal piece 1 rear will be fixed to horizontal piece 1 is fixed on blackboard and can uses, and the fixing horizontal piece 4 interior slip of track runner 2 forwardly of can sliding, the movable vertical chi 3 interior slip of track runner 2 up simultaneously.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art make in essential scope of the present utility model, also should belong to protection domain of the present utility model.
