Abstract
The utility model discloses an electromagnetic damping demonstration device, comprising base plates, a vertical plate, and magnet pieces. The bottom of the vertical plate is connected with the base plates through screws. A side surface of the vertical plate is connected with an aluminium pipe and an organic pipe which are parallel with each other through connection fixing devices. The bottoms of the aluminium pipe and the organic pipe are respectively sleeved with a sleeve. The number of the magnet pieces is two. The connection fixing device is a U-shaped snap-gauge, and the U-shaped snap-gauge is fixedly connected with the vertical plate through screws. Each of the aluminium pipe and the organic pipe is fixed on the vertical plate through two U-shaped snap-gauges. Beneficial effects of the device is that the device is simple in structure, reasonable in design, low in manufacturing cost, simple in operation, and convenient in use, and the device makes students understand electromagnetic induction phenomenon.
Description
Technical field
The utility model relates to experiment instrument tool technical field, relates in particular to a kind of electromagnetic damping presentation device.
Background technology
At present, in teaching when children learn these knowledge of electromagnetic induction phenomenon, it is larger that difficulty is understood in discovery, and be exactly with experiment, this principle to be described with existing technology, experimental facilities neither be fine, do also accurate not, and can not make children more deep understand this principle, thereby more teaching brings difficulty.
Utility model content
For the deficiencies in the prior art, the utility model provides electromagnetic damping presentation device.
To achieve these goals, the utility model solves scheme that its technical matters is taked: electromagnetic damping presentation device, comprise base plate, riser and magnet piece, riser bottom is fixedly connected with base plate by screw, the side of riser is connected with aluminum pipe parallel to each other and organic pipe by being connected and fixed device, each cover of the bottom of aluminum pipe and organic pipe has a sleeve, riser is transparent poly (methyl methacrylate) plate, on base plate, be lined with sponge, aluminum pipe and organic pipe are provided with scale, and base plate bottom surface is provided with for holding the sucker of desktop.
Described magnet piece has 2.
The described device that is connected and fixed is U-shaped clamp.
Described U-shaped clamp is fixedly connected with by screw with riser.
Described aluminum pipe and organic pipe are respectively fixed on riser by two U-shaped clamps.
On riser, be provided with the whether vertical pendant of a measurement riser, can judge that whether riser is vertical.
Base plate is provided with weighs the whether level meter of level of base plate, can judge whether level of whole instrument.
On the sidewall of aluminum pipe and organic pipe, be provided with speed detector, can measure the travelling speed of magnet piece.
The beneficial effects of the utility model: this utility model is simple in structure, reasonable in design, low cost of manufacture; Simple to operate, use easily, more can allow student understand electromagnetic induction phenomenon.
Accompanying drawing explanation
Fig. 1 is STRUCTURE DECOMPOSITION schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, electromagnetic damping presentation device, comprise base plate 1, riser 2 and magnet piece 3, riser 2 bottoms are fixedly connected with base plate 1 by screw, the side of riser 3 is connected with aluminum pipe parallel to each other 5 and organic pipe 6 by being connected and fixed device 4, each cover of the bottom of aluminum pipe 5 and organic pipe 6 has a sleeve 7, described magnet piece 3 has 2, described is connected and fixed device 4 for U-shaped clamp, described U-shaped clamp is fixedly connected with by screw with riser 3, and described aluminum pipe 5 and organic pipe 6 are respectively fixed on riser by two U-shaped clamps.
During use, only use riser 2 is placed in horizontal table top, there is base plate 1 vertical 2 plate bottoms by screw lock, on riser 2, by being connected and fixed device 4, be connected with aluminum pipe parallel to each other 5 and organic pipe 6, bottom at aluminum pipe 5 and organic pipe 6 is placed with sleeve 7, then by first allowing magnet piece 3 vertically place and entered by another mouth of pipe on organic pipe 6, unclamp magnet piece 3, magnet piece 3 falls at organic pipe 6 from static beginning, magnet piece falls in the sleeve of base plate 17 in 3 very short times, then take magnet piece 3 away, aluminum pipe 5 is interior carries out above-mentioned the same action by magnet piece 3.The impact of more different materials on magnet.
The beneficial effects of the utility model: this utility model is simple in structure, reasonable in design, low cost of manufacture; Simple to operate, use easily, more can allow student understand electromagnetic induction phenomenon.
