Description

Technical Field

[0001] The utility model relates to the technical field of physical experiments, in particular to a multi-layer supporting rod structure. Background Art

[0002] In some physical experiments, some equipment is needed to be used for testing in order to obtain data. However, during the use of these devices, they need to be fixed and stabilized to ensure the accuracy of the data obtained.

[0003] The existing authorization publication number "CN208422169U" includes a base, a support frame, a vertical scale, a mounting sleeve, a fixing bolt, a fixing rod, a fixing clamp, a support rod, an anti-slip sleeve, a frosted plate, a horizontal scale, a level and an adjustment leg. The beneficial effects of the utility model are: the mounting sleeve is sleeved on the support frame and can move up and down freely on the support frame, which can drive the fixing rod and the support rod to move up and down, so as to facilitate the needs of the experiment. A plurality of fixing clamps are evenly fixed on the bottom of the fixing rod, which can effectively fix devices such as a dot timer and a dynamometer. A vertical scale is fixed on the surface of the support frame and a horizontal scale is fixed on the base next to the frosted plate, which is convenient for measuring horizontal and vertical distances during experiments without using a ruler separately. An inward concave groove is left on the base and a level is installed in the groove, so it is very convenient to observe whether the base is horizontal.

During the experiment, if affected by external force, the object will shake and cannot maintain its horizontal state, which in turn affects the accuracy of the experimental data. In addition, the manuscript device simply places some experimental equipment, and some equipment needs to ensure stability, and it cannot adapt to the experimental equipment. Utility Model Content

The clamping plate 24 and the mounting plate 11 are hinged to each other, and a plurality of sets of through grooves 10 are evenly provided on the mounting plate 11.

[0029] Working principle: During the gravity acceleration test, the funnel is placed between the two groups of clamping blocks 95, and then the bidirectional threaded rod 91 is rotated. During the rotation process, the two groups of second side plates 92 and the second sliding rod 93 are driven to approach each other. During the approach process, the two groups of clamping blocks 95 clamp the funnel, and then the two groups of clamping plates 24 are flipped so that the two groups of clamping plates 24 do not clamp the bottom of the funnel. Then the funnel is vertical under the action of gravity. During the vertical process, the clamping plates 24 are released again, and then the second spring 25 drives the two groups of clamping plates 24 to move. At this time, the clamping plates 24 clamp the bottom of the funnel, thereby ensuring the stability of the funnel and preventing the funnel from deflecting. Then, when the stroboscopic instrument is used for testing, it can prevent the dripping water from scattering everywhere and affecting the data.

[0030] During the plane mirror imaging experiment, the plane mirror is first placed inside the two groups of support frames 17, and then the two groups of movable plates 6 are pulled to move, so that the first slide bar 4 is no longer inserted into the inside of the jack 23, thereby releasing the fixed state of the sleeve 5, and then the sleeve 5 is pulled downward. When the sleeve 5 moves downward, the pressing plate 3 presses the top of the glass to ensure the parallel state of the plane mirror. If the plane mirror is unstable, the threaded rod 19 at any position is rotated, and then the threaded rod 19 drives the top plate 20 to move upward, and pushes a corner of the plane mirror during the upward movement, thereby adjusting the plane to ensure the stability of the plane mirror.

[0031] During the imaging process of the convex lens, the candle, convex mirror and light screen are first clamped in the placement groove 15 respectively, and then the multiple sets of mounting seats 13 are pulled to adjust their positions. During the adjustment process, the first magnet 14 is adsorbed on the second magnet 16, thereby ensuring the stability during the placement process, and through the action of the connecting groove 21, it can also ensure that the mounting seat 13 always moves along a straight line.
