Abstract
The utility model, which belongs to the physics education apparatus and equipment field, discloses a demonstrating instrument for a plane lifting principle. The demonstrating instrument comprises a pedestal box, a fan, and a plastic foam plane model. The fan is arranged at one side of the top of the pedestal box and a sliding rail that is perpendicular to the fan is arranged at the other side of the top of the pedestal box. A sliding plate capable of being slided left and right is arranged on the sliding rail; a forked tail-shaped spout is arranged above the sliding plate; a slide block that can be slided back and forth freely is arranged inside the forked tail-shaped spout; and two guide metal strips are arranged on the slide block and a plane model that can be slided up and down freely is arranged on the guide metal strips; and the outlet of the fan corresponds to the plane model. Compared with the prior art, the technology employed by the utility model enables the novel demonstrating instrument to have characteristics of reasonable design, simple structure, easiness of processing, convenience usage, low processing cost and obvious experiment effect and the like.
Description
Technical field
The utility model relates to the physics educational apparatus apparatus field, specifically airplane ascensional force principle demonstration device.
Background technology
Existing airplane ascensional force principle demonstration device receives the influence of supply voltage through regular meeting; Because the power of model quality and blower fan all is certain, the distance between blower fan and the model also is changeless, when mains fluctuations; Can influence the wind-force of blower fan; Cause experiment effect undesirable, can not clearly demonstrate, reduced quality of instruction to the student.
Summary of the invention
The technical assignment of the utility model is to above weak point, provide a kind of easy to use, processing cost is low, the tangible airplane ascensional force principle demonstration of experiment effect device.
The utility model solves the technical scheme that its technical matters adopted: this airplane ascensional force principle demonstration device comprises base box, blower fan and plastic foam model aircraft; Top one side of base box is provided with blower fan; Base box top opposite side is provided with the slide rail vertical with blower fan, and the slide plate that can horizontally slip is set on the slide rail, and the slide plate top is provided with the dovetail chute; Be provided with in the dovetail chute can before and after the slide block that is free to slide; Slide block is provided with two guiding bonding jumpers, and the guiding bonding jumper is provided with the model aircraft that can freely slide up and down, and the air port of blower fan is corresponding with model aircraft.
Described slide plate is provided with rotating shaft, and the bottom of dovetail chute is provided with swivelling chute, and swivelling chute cooperates with rotating shaft.
Described two guiding bonding jumper vertical level.
The airplane ascensional force principle demonstration device of the utility model is compared with prior art, have reasonable in design, simple in structure, be easy to processing, easy to use, characteristics such as processing cost is low, experiment effect is obvious.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is the structural representation of airplane ascensional force principle demonstration device.
Among the figure: 1, base box, 2, blower fan, 3, the dovetail chute, 4, slide block, 5, the guiding bonding jumper, 6, model aircraft, 7, slide plate, 8, slide rail, 9, rotating shaft, 10, swivelling chute.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
The airplane ascensional force principle demonstration device of the utility model; Its structure comprises base box 1, blower fan 2 and plastic foam model aircraft 6, and top one side of base box 1 is provided with blower fan 2, and base box 1 top opposite side is provided with the slide rail 8 vertical with blower fan 2; The slide plate 7 that can horizontally slip is set on the slide rail 8; Slide plate 7 tops are provided with dovetail chute 3, and slide plate 7 is provided with rotating shaft 9, and the bottom of dovetail chute 3 is provided with swivelling chute 10; Swivelling chute 10 cooperates with rotating shaft 9, through cooperate the suitably adjusting angle of swivelling chute 10 with rotating shaft 9; Be provided with in the dovetail chute 3 can before and after the slide block 4 that is free to slide; Slide block 4 is provided with two guiding bonding jumpers 5; Article two, guiding bonding jumper 5 vertical level, guiding bonding jumper 5 is provided with the model aircraft 6 that can freely slide up and down, and the air port of blower fan 2 is corresponding with model aircraft 6.
When the student does experimental demonstration, can be according to the variation of voltage, move left and right slide plate 7 with move forward and backward slide block 4, thereby keep tangible experiment effect.
Its processing and fabricating of airplane ascensional force principle demonstration device of the utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
