Also include the box being fixed on pedestal, being placed with in described box can convex lens rigidly connected with movable pulley, when described convex lens replace the second weight block and movable pulley be rigidly connected time, described light source, convex lens, white screen center conllinear, for lens imaging lecture experiment.
As optimization, also it is placed with upper end in described container and exposes the straight-bar of liquid level, be used for demonstrating refraction effect.
As optimization, described left slider and be provided with on right slide block and mark closely screw, by the fixing left slider of holding screw and right slide block position on crossbeam, the demonstration of convenient experiment.
As optimization, described crossbeam and left column are provided with graduation mark, increase the quantization property of lecture experiment.
As optimization, the slide rail of described crossbeam also slipping the block having anti-locking pulley to swing, the groove that described block lower end is provided with and movable pulley thickness is adaptive, by groove card driving pulley, it is prevented that it swings, it is to avoid lens imaging experiment is disturbed.
As preferably, the liquid in described container is water, convenient acquisition, and is easy to observe.
This utility model beneficial effect: a set of apparatus for demonstrating can realize the kinds of experiments demonstrations such as fixed pulley, movable pulley, buoyancy, linker, convex lens and refraction effect, effectively reduce teaching aid kind, facilitate teacher to carry, be beneficial to contrast memory when Students ' Comprehensive is reviewed and observe.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is the schematic diagram in Fig. 1 after sequence 19 and sequence 6 reversing of position.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical scheme of utility model is described in detail.
A kind of multifunctional physics teaching apparatus for demonstrating as shown in Figure 1, including pedestal 1 and the support being fixed on pedestal 1, support includes the crossbeam 5 with slide rail, it is fixed with the left column 4 of light source 3 and is fixed with the right column 20 of white screen 15, crossbeam 5 and left column 4 are provided with graduation mark, the slide rail slip up of crossbeam 5 is connected to the left slider 8 with holding screw 10, right slide block 11 and block 9, left slider 8, right slide block 11 and block 9 can pass through holding screw 10 and fix its position on crossbeam 5, it is connected to fixed pulley 12 below right slide block 11, the rope 7 walking around fixed pulley 12 it is connected to below left slider 8, rope 7 end is connected to the first weight block 13, rope 7 is additionally provided with the movable pulley 14 with the second weight block 6 between left slider 8 and fixed pulley 12, the lower end of block 9 is provided with the groove adaptive with movable pulley 14 thickness, pedestal 1 immediately below the second weight block 6 is provided with container 16, clear water is filled in container 16, container 16 is internally provided with dividing plate 17, container 16 is divided into two parts by dividing plate 17, dividing plate 17 lower end not with the base contact of container 16, in order to carry out refraction experiment demonstration, in container 16, place straight-bar 18, it is possible to direct vision is to the upper and lower two-part difference of the water surface of straight-bar 18 place.
Pedestal 1 is further fixed on box 2, be placed with in box 2 can convex lens 19 rigidly connected with movable pulley 14, as in figure 2 it is shown, do convex lens experiment time, convex lens 19 replaces the second weight block 6 be rigidly connected with movable pulley 14, light source 3, convex lens 19, white screen 15 center conllinear.
