Abstract
The invention belongs to the technical field of teaching aid, and more specifically relates to an adjustable support used for chemical experiment. The adjustable support comprises an annular holding surface and at least three uniformly distributed fixed rods fixed at lower part of the annular holding surface, the fixed rod comprises a pair of upper supporting arms, a pair of lower supporting arm, a pedestal, a screw and a nut cooperated to the screw, the ends of the pair of upper supporting arms respectively form gears and are engaged and pin-jointed on the fixed rod; the end of the pair of the lower supporting arms respectively form gears and are engaged and pin-jointed on the pedestal; the upper supporting arm at left side and the lower supporting arm are pin-jointed on the nut, the upper supporting arm at right side and the lower supporting arm are pin-jointed outside a through hole, the screw passes through the through hole and is fixed on the nut; accordingly, the adjustable support used for the chemical experiment is conveniently adapted to different heaters, classroom time can be saved, and the adjustable support has the advantages of reliability, safety and utility.
Description
Technical field
The invention belongs to teaching aid technical field, be specifically related to a kind of adjustable support being applied to chemical experiment.
Background technology
On laboratory, often tripod can be used.But existing support height is non-adjustable, can not adapt to the occasion of the heater of differing heights, this brings a lot of inconvenience to experiment.
Summary of the invention
The object of the invention is to overcome the nonadjustable problem of existing support height.
For this reason, the invention provides a kind of adjustable support being applied to chemical experiment, comprise annular support surface and be fixed at least three fixed bars of evenly arranging below annular support surface, described fixed bar also comprises: supporting arm, a pair lower support arm, base, screw mandrel and the nut that coordinates with screw mandrel on a pair, on a pair, supporting arm end becomes gear respectively and engages, and pin joint is on fixed bar; A pair lower support arm end becomes gear respectively and engages, and pin joint is on base; On left side, supporting arm and lower support arm pin joint are on nut, and on right side, supporting arm and lower support arm pin joint are outside through hole, and screw mandrel is fixed on nut through through hole.
Beneficial effect of the present invention: this adjustable support being applied to chemical experiment provided by the invention, comprise annular support surface and be fixed at least three fixed bars of evenly arranging below annular support surface, described fixed bar also comprises: supporting arm, a pair lower support arm, base, screw mandrel and the nut that coordinates with screw mandrel on a pair, on a pair, supporting arm end becomes gear respectively and engages, and pin joint is on fixed bar; A pair lower support arm end becomes gear respectively and engages, and pin joint is on base; On left side, supporting arm and lower support arm pin joint are on nut, and on right side, supporting arm and lower support arm pin joint are outside through hole, and screw mandrel is fixed on nut through through hole; Therefore, this is applied to the adjustable support of chemical experiment, can adapt to different heaters easily, save time in classroom, very reliably, safety, practical.
Below with reference to accompanying drawing, the present invention is described in further details.
Accompanying drawing explanation
Fig. 1 is the adjustable support structural representation being applied to chemical experiment;
Fig. 2 is the adjustable support partial enlarged drawing being applied to chemical experiment.
In figure: 1, annular support surface; 2, fixed bar; 3, upper supporting arm; 4, lower support arm; 5, base; 6, screw mandrel; 7, nut; 8, through hole.
Detailed description of the invention
Embodiment one:
Above-mentioned a kind of adjustable support being applied to chemical experiment as shown in Figure 1, comprise annular support surface 1 and be fixed at least three fixed bars 2 of evenly arranging below annular support surface 1, it is characterized in that: described fixed bar 2 also comprises: supporting arm 3, a pair lower support arm 4, base 5, screw mandrel 6 and the nut 7 that coordinates with screw mandrel 6 on a pair, on a pair, supporting arm 3 end becomes gear respectively and engages, and pin joint is on fixed bar 2; A pair lower support arm 4 end becomes gear respectively and engages, and pin joint is on base 5; On left side, supporting arm 3 and lower support arm 4 pin joint are on nut 7, and on right side, supporting arm 3 and lower support arm 4 pin joint are outside through hole 8, and screw mandrel 6 is fixed on nut 7 through through hole.
This adjustable support being applied to chemical experiment, can adapt to different heaters easily, save time in classroom, and it is more convenient that the program makes support use, not easily landing, very reliably, safety, practical.
More than exemplifying is only illustrate of the present invention, does not form the restriction to protection scope of the present invention, everyly all belongs within protection scope of the present invention with the same or analogous design of the present invention.
