It is equipped with flexible strip above the support tube, plugs and be fixed with locating rod in the upper end of support tube described in every, positions
Support tube is stretched out in the upper end of bar, and the upper end of every locating rod is connected with flexible strip.
In use, by sliding support pipe to change the height of locating rod, to form economic curve of different shapes, just
Understand and learn in student, improves efficiency of teaching.
Flexible strip, locating rod and support tube three fixation hold together, and adjust flexibility by sliding support pipe
The shape of item, effectively flexible strip to be avoided to fall off, so that some unnecessary operations are reduced, to improve the easy to operate of this sand table
Property.
Rubber sleeve and connecting tube offset to form certain friction, and make support tube by above-mentioned friction come positioning support pipe
Movement it is synchronous with limit carry out, to reduce operating procedure, to further increase operation convenience.
In above-mentioned economics simulation sand table, annular dovetail slot, and ring are offered on the lateral wall of above-mentioned support tube
Shape dovetail groove and support tube coaxial arrangement, have on the inner sidewall of above-mentioned rubber sleeve and the matched annular snap of annular dovetail slot
Button, and annular buckle is in annular dovetail slot.Using above-mentioned design, the connection for effectively increasing rubber sleeve and support tube is firm
Property, the job stability of Lai Tigao sand table.
In above-mentioned economics simulation sand table, the lateral wall of above-mentioned rubber sleeve is equipped with conquassation slot in a ring, pressure
Routed slot and rubber sleeve coaxial arrangement, and it is triangular in shape to be crushed section of the slot in rubber sleeve axial direction.Under conquassation slot effect, make rubber
Gum cover is more easily-deformable, the friction between Lai Tigao rubber sleeve and connecting tube, the effect that Lai Tigao support tube is positioned, to improve
The job stability of this sand table.
In above-mentioned economics simulation sand table, the flexible strip is connected by way of bonding with locating rod.
Compared with prior art, this economics simulation sand table has the advantage that
1, flexible strip, locating rod and support tube three fixation hold together, and soft to adjust by sliding support pipe
The shape of property item, effectively to avoid flexible strip from falling off, so that some unnecessary operations are reduced, to improve the operation side of this sand table
Just property.
2, rubber sleeve and connecting tube offset to form certain friction, and by above-mentioned friction come positioning support pipe, make to support
The movement of pipe is synchronous with limit to be carried out, to reduce operating procedure, to further increase operation convenience.
