Embodiment 1

[0016] The slider for the steam suspension experiment includes a slider body 1. The slider body 1 is a rectangular block, and the bottom of the rectangular block is provided with a groove that is sunk into the inside of the rectangle block. The inside of the slider body 1 becomes a hollow structure, and the groove reduces the sliding. Due to the weight of the block body 1 itself, the groove is hemispherical, and the gas blows up the slider body 1 from the bottom. Due to the existence of the hemispherical groove, its contact area is more increased, so that the support slider does not need a large Gas power can achieve suspension. The upper center of the slider body 1 is provided with a cylindrical fixing hole 2 recessed into the slider body 1. The slider is used to complete various experiments. It is necessary to install various measurement physical quantities on the upper part of the slider body 1. For experimental equipment, the fixing hole 2 provides a place for it to be plac...

Embodiment 2

[0018] The four sides of the slider main body 1 near the bottom edge are provided with a rectangular plate 6 with the same length as the side. The lower surface of the rectangular plate 6 is flush with the lower surface of the slider main body 1. The area blown by the airflow bears more buoyancy from the airflow, reducing the airflow required by the airflow per unit area, thereby reducing energy consumption. The connection of the rectangular plate 6 at the bottom of the slider body 1 is connected by an arc, and four The arrangement of the rectangular plate 6 does not close the corners of the slider main body 1 , and the material of the rectangular plate 6 and the slider main body 1 is the same.

Embodiment 3

[0020] The front and rear ends of the slider main body 1 are provided with horizontal cylindrical connecting rods 7, the connecting rods 7 carry the connecting function, and the end of the connecting rods 7 away from the slider main body 1 is provided with a ring protrusion 8, the protrusion 8 is better The fixed connection block prevents it from slipping. The connecting rod 7 is respectively connected to the front connecting block 9 and the rear connecting block 10. The material of the front connecting block 9 and the rear connecting block 10 is the same as that of the slider main body 1, and the density of the same material is the same, so that the output of the air flow can be controlled more conveniently. The front connecting block 9 is the same as the rear connecting block 10. The cutting surface of the front connecting block 9 is a right-angled trapezoid, and the upper bottom surface of the right-angled trapezoid is provided with arc edges, which is more conducive to the ...

Abstract

The invention relates to the technical field of experimental devices, specifically to a slider used for a steam suspension experiment. The slider for the steam suspension experiment comprises a slider main body which is a rectangular block, wherein the bottom part of the rectangular block is provided with a groove which is sunken to the interior of the rectangular block; the groove is of a hemispherical shape; the position of the center of the upper part of the slider main body is provided with a cylindrical fixed hole which is sunken into the slider main body; a circular-ring-shaped fixed clip is arranged in the fixed hole; a plurality of fixed sheets which obliquely extend upward from the edge of the bottom part of the fixed clip are arranged on the fixed clip; one surface, far away from the inner wall of the fixed hole, of each fixed sheet is provided with a fixed clip ball; and the fixed clip is made of plastic. The slider used for the steam suspension experiment provided by the invention solves the problems of overmuch required power and overlarge air resistance for slider suspension in the prior art, and has extensive application range in various laboratories.

Description

technical field [0001] The invention belongs to the technical field of experimental devices, in particular to a slider for steam suspension experiments. Background technique [0002] In the steam suspension experiment, there is an air hole in the lower part of the guide rail. Due to the existence of the air pump, the gas is continuously ejected from the inside of the air hole. The slider on the upper part of the guide rail is continuously ejected upward due to the gas, and a relatively thin layer is formed between the lower surface of the slider and the guide rail. Due to the existence of the air film, when the slider is suspended, when the slider moves, the resistance caused by friction is almost negligible. The laboratory usually uses this principle to carry out various experiments. [0003] Most of the traditional sliders are solid, and a relatively large gas output must be used to provide sufficient power, which will inevitably cause some gas to be wasted. The suspensio...
