Detailed Description

As shown in fig. 1, an instrument positioning and fixing support for teaching experiments comprises an arched support frame 1 and horizontal support legs 2 supported at the lower end of the support frame 1, triangular reinforcing plates 12 are respectively fixed at bending positions on two sides of the top of the support frame 1, the strength of the support frame 1 can be enhanced by the triangular reinforcing plates 12, an anti-skid rubber pad 13 is respectively arranged on the lower surface of each support leg 2, the anti-skid rubber pads 13 are convenient to place on a table top for use and are more stable, and an anti-skid dropping function is achieved;

a tripod head stabilizer 4 capable of freely rotating is fixed in the middle of the top of the support frame 1 through a fixing cylinder 3, the tripod head stabilizer 4 is a three-axis stabilizer (such as a shadow RONIN-S, a smart cloud Z1-Rider-M, a flying science MINI3Dpro three-axis airborne brushless tripod head stabilizer and the like in the Xinjiang, the existing three-axis stabilizer is mature in structure and control and can be better applied), a vertical frame 5 is fixed on the upper surface of the horizontal end of a third axis, the tripod head stabilizer 4 is controlled through tripod head electric control, a dual-motor control circuit for a rocker arm electric tripod head and a remote control industrial camera tripod head is specially developed, an electronic brake and electronic damping technology is created, most direct current speed reducing motors in import and domestic are compatible, various rocker universal directions are compatible, and all curve parameters can be adjusted according to the preference of a user; stepless speed regulation (different from sectional speed regulation, and two paths of speed regulation are independently adjustable), starting damping and stopping damping are respectively adjustable (from zero damping to 2 seconds of continuous stepless adjustment), and when the electric quantity of the battery is insufficient, small-amplitude operation torque compensation can be started; overcurrent, locked rotor and limit multiple protection are adopted to prevent the motor from being burnt, advanced SMT surface mounting factory flow line production is realized, a control unit provided by Philips of an MCU manufacturer does not use crystal oscillation, low-temperature vibration stopping and dead halt are avoided, and the navigation mark plug is adopted for leading wires conveniently;

automatically controlled main control leveling of cloud platform, make frame 5 be in vertical state, effectively prevent that the test tube from empting and drop, on the other hand, it shakes the test tube with the hand to rock frame 5 dummy when needing, frame 5 level and inside the latter half be fixed with horizontally picture peg 6, vertical division has a plurality of jacks 7 that supply the test tube to pass on the picture peg 6 respectively, be fixed with a plurality of levels and the transparent limiting plate 8 that is parallel to each other in the frame 5 of picture peg 6 below respectively, it has the trompil that just the diameter is the same with picture peg 6 jack 7 alignment respectively to open on every transparent limiting plate 8, the vertical portion in both sides of frame 5 is provided with scale mark 9 respectively, every adjacent limiting plate 8 equidistance just corresponds with scale mark 9.
