The present invention technical solution be：A kind of experiment with simple pendulum device by base leveling nut (1), base platform (2),
Square vertical support frame (3), vertical support frame both sides chute (4), the slide one (5) with wing screw, the cunning with wing screw
Seat two (6), with two wing nut Double-layer clamp board mounts one (7), with two wing nut Double-layer clamp board mounts two (8), thin cotton
Line (9), diameter 3cm steel balls (10), spirit level, timer (12), photoelectric sensor (13), graduated scale (14) composition.Its base
Central in-house spirit level (11), can cause simple pendulum device level by adjusting base nut (1), and thin cotton thread (9), which hangs on, matches somebody with somebody
Two wing nut Double-layer clamp board mounts one (7), through with two wing nut Double-layer clamp board mounts two (8), lower end suspension is straight
Footpath 3cm steel balls (10), in square vertical support frame (3) calibrated scale, steel ball (10) bottom is zero graduation, and changing pendulum length only needs
Slide with two wing nut Double-layer clamp board mounts two (8), while writing down with two wing nut Double-layer clamp board mounts two (8)
The concordant reading in lower section can read pendulum length.It is the week that photoelectric sensor (13) can be swung with accurate recording below steel ball (10)
Phase.Wherein, it is fixed on the slide two (6) with wing screw, can passes through with two wing nut Double-layer clamp board mounts two (8)
The slide two (6) with wing screw is slided up and down, changes the position of crossbeam；With two wing nut Double-layer clamp board mounts two (8),
Double-deck clamping plate can be fixed by wing nut to clamp cycloid；It is fixed on two wing nut Double-layer clamp board mounts two (8)
On slide one (5) with wing screw, change position is moved up and down by the slide one (5) with wing screw, while locking is matched somebody with somebody
Two wing nuts of two wing nut Double-layer clamp board mounts two (8), can arbitrarily change pendulum length, straight from graduated scale (14)
Connect reading；Graduated scale (14) is fixed in square vertical support frame (3), graduated scale minimum indexing 1mm, pendulum length can directly from
Read at two (8) lower end line balls of wing nut Double-layer clamp board mount two；Spirit level (11) is embedded on base platform (2), can
Directly to go out simple pendulum device base level condition from level bubble position display.
The present invention has advantages below compared with existing apparatus：
(1) spirit level built in is easy to simple pendulum device base Level tune,
(2) observe easy to adjust.Experimental provision vertical rack both sides are equipped with chute, are changed by sliding up and down regulation plastic clip
Become pendulum length and be easy to reading.
(3) photoelectricity door is installed below swing ball, can accurately readout interval number and cycle.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model device
Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
As shown in figure 1, the utility model is main by base leveling nut (1), base platform (2), square vertical support frame
(3), vertical support frame both sides chute (4), the slide one (5) with wing screw, the slide two (6) with wing screw, with two
Wing nut Double-layer clamp board mount one (7), with two wing nut Double-layer clamp board mounts two (8), thin cotton thread (9), diameter 3cm steel
Ball (10), spirit level (11), timer (12), photoelectric sensor (13), graduated scale (14) composition.During experiment, adjusting base is adjusted
Flush nut (1), makes spirit level (11) bubble being embedded on base platform (2) centrally located, adjusts the slide with wing screw
