Embodiment

The utility model adopts integrated designing technique, the utilization optimal design method, and with all middle and primary schools' normal experiment project unified plannings, the technical parameter of the instrument that each is concrete is divided into " related design parameter " and " dereferenced design parameter ".Make the utility model be different from existing all other middle and primary schools' experimental apparatuss.Related design parameter is meant that these parameters and Other Instruments have mechanical connection or be electrically connected or being connected etc. of light.The dereferenced parameter is meant that this design parameter is that this instrument institute is exclusive, and is uncorrelated with Other Instruments.

The utility model is made up of pedestal, plug and experiment components and parts, wherein pedestal be used for each parts of this combination experiment instrument connection, deposit, and with being connected of other support or platform, be convenient to carrying out smoothly of each experiment.See Fig. 1.

Pedestal is plate-like shape, which is provided with many registration hole-circular hole 1 and many locating slot-dovetail grooves 2.Can splice between the pedestal, can three-dimensional join, each piece base plate all has positioning screw hole for four jiaos.Pilot hole-circular hole 1 on the described pedestal is regular layout or evenly arranges, the locating slot-dovetail groove 2 on the described pedestal open at base-plates surface and longitudinally, lateral arrangement.As Fig. 1, Fig. 2, Fig. 3.
