Technical Field

The invention relates to the technical field of demonstration equipment, in particular to a vehicle inertia demonstration device.

Background

Inertia and centrifugation phenomena are key points and difficult points of physics in middle schools, and the understanding of inertia can only be obtained through observing phenomena to draw an intuitive conclusion, so that students can learn in interest, and the understanding of knowledge is deepened. In order to help teachers to effectively teach, a series of demonstration devices are provided, in the prior art, patent publication numbers CN106023733A, CN202058349U, CN204884352U, CN204680270U and the like are all studied on inertia phenomena, however, the above patents have not been studied on vehicle inertia and demonstration between mass and vehicle inertia, which hardly arouses interest of students, and the whole structure is too simple, and the demonstration is performed by teachers on a platform, and some students may not see clearly, which affects teaching quality.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a vehicle inertia demonstration device which is large in size and more intuitive.

In order to achieve the purpose, the invention adopts the following technical scheme: a vehicle inertia demonstration apparatus, characterized by: the device comprises an adjustable bracket, two synchronous track platforms, a bottom supporting wheel, a supporting rod, an adjusting rod, a moving wheel and a guide groove; two synchronous track platform installations are in the adjustable support, the bottom sprag wheel sets up adjustable support's one end, the bracing piece is two, and the top articulates respectively adjustable support's bottom, it is two to remove the wheel, connects together through synchronizing shaft, the bottom of bracing piece through the axle sleeve with synchronizing shaft connects, it is two to adjust the pole, the bottom of adjusting the pole through the axle sleeve with synchronizing shaft connects, and the top of adjusting the pole links together through a connecting rod, the connecting rod passes the guide way, the both ends of connecting rod through lock nut with the connecting rod with the guide way is fixed.

Preferably, the two track platforms are arc-shaped, and two sides of the two synchronous track platforms are bent upwards and fixed with the adjustable support through bolts.

Preferably, the adjustable support is internally provided with a connecting plate, the connecting plate is provided with a connecting groove, and two sides of the two synchronous track platforms are connected together through bolts and the connecting groove.

The adjustable support has the advantages that the size of a desk can be made, the adjustable support can be placed on a platform or on the ground, the adjustable support can be seen by students in back rows according to the designed volume sizes of different places in actual operation, the angle of the adjustable support can be adjusted within the range of 9-28 degrees, the demonstration of the influence of gravity acceleration on the speed of a vehicle is increased, and the whole demonstration process is more visual.

Detailed Description

the following detailed description of the preferred embodiments will be made with reference to the accompanying drawings. As shown in fig. 1-3, a vehicle inertia demonstration device comprises an adjustable bracket 1, two synchronous track platforms 2, bottom support wheels 3, support rods 4, an adjusting rod 5, moving wheels 6 and a guide groove 7; two synchronous track platform is installed in adjustable support, the bottom sprag wheel sets up adjustable support's one end, the bracing piece is two, and the top articulates respectively adjustable support's bottom, it is two to remove the wheel, links together through synchronizing shaft 8, the bottom of bracing piece pass through the axle sleeve with synchronizing shaft connects, it is two to adjust the pole, the bottom of adjusting the pole pass through the axle sleeve with synchronizing shaft connects, and the top of adjusting the pole links together through a connecting rod 9, the connecting rod passes the guide way, the both ends of connecting rod pass through lock nut with the connecting rod with the guide way is fixed. The two track platforms are arc-shaped, and two sides of the two synchronous track platforms are bent upwards and fixed with the adjustable support through bolts.

The height of the adjustable support of the device can be adjusted within a range of 9-28 degrees, the larger the angle is, the faster the speed of the two trolleys is, and the farther the two trolleys run, during the experiment, the two trolleys with certain weight are placed on two synchronous track platforms, the balancing weight is installed on one trolley, so that the two trolleys slide downwards from the same height, and the sliding distance is compared, so that a student visually observes the inertia experiment.

In addition, the inside of adjustable support is equipped with connecting plate 10, is equipped with the spread groove on the connecting plate, and the both sides of two synchronous track platforms are passed through the bolt and are linked together with the spread groove. The advantage that sets up like this is convenient for adjust synchronous track platform, and two synchronous track platforms are all made by corrosion resistant plate, can be through the bolt position of adjusting from top to bottom in the spread groove, make synchronous track platform be a straight line, can make synchronous track platform be an pitch arc, can observe like this to walk the dolly of straight line and arrive the bottom earlier, or walk curved dolly and arrive earlier.

The adjustable support can be manufactured into a desk, and can be seen by students in the back row, the angle of the adjustable support can be adjusted within the range of 9-28 degrees, the demonstration of the influence of gravity acceleration on the speed of a vehicle is increased, and the whole demonstration process is more visual.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
