1. A portable pilgrimage pendulum is characterized in that: the base is provided with a plurality of accommodating grooves, telescopic vertical columns are hinged in the accommodating grooves respectively, a rectangular groove is formed in the central position of one side of the base, a cycloidal telescopic vertical column is hinged in the rectangular groove, a cross beam is fixed at the top of the cycloidal telescopic vertical column, the tail end of the cross beam is connected with one end of a cycloidal, and the other end of the cycloidal is connected with a pendulum ball.

2. The portable pendulum of claim 1 wherein the receiving groove has a length that is the same as the length of the telescopic post when it is contracted, and the elongated groove has a length that is the same as the length of the white line when it is contracted.

Technical Field

The invention relates to the technical field of demonstration equipment, in particular to a portable pilgrimage pendulum.

background

The pilgrimage pendulum is a demonstration instrument for demonstrating that human eyes are sensitive to hysteresis phenomena of low-brightness light and high-brightness light. The existing Poisson pendulum demonstration instrument comprises a large-size Poisson pendulum main body upright rod box, a pendulum ball swings in a plane between two rows of metal rods, and a light attenuation mirror is worn to observe the track of the pendulum ball. The Pushi pendulum demonstration instrument has the advantages of high manufacturing cost, poor economical efficiency, large volume and weight, inconvenience in carrying and use.

Disclosure of Invention

The invention aims to overcome the defects of the technology and provide a portable pilgrimage pendulum which is large in size and more intuitive.

In order to achieve the purpose, the invention adopts the following technical scheme: a portable pilgrimage pendulum is characterized in that: the base is provided with a plurality of accommodating grooves, telescopic vertical columns are hinged in the accommodating grooves respectively, a rectangular groove is formed in the central position of one side of the base, a cycloidal telescopic vertical column is hinged in the rectangular groove, a cross beam is fixed at the top of the cycloidal telescopic vertical column, the tail end of the cross beam is connected with one end of a cycloidal, and the other end of the cycloidal is connected with a pendulum ball.

Preferably, the length of the accommodating groove is the same as the length of the telescopic upright post after being reduced, and the length of the long groove is the same as the length of the white line after being reduced.

The telescopic vertical column in the device is placed into the containing groove when being retracted, and the small balls and the cycloid are also placed into the corresponding holes on the plate, so that the device is convenient to carry, the volume and the weight of the device are greatly reduced, and the price of the device is greatly reduced; simultaneously, this application simple structure, easy and simple to handle, the practicality is strong, is fit for being used for the physics teaching of middle school and university, also is suitable for the show in science and technology museum.

Detailed Description

The following detailed description of the preferred embodiments will be made with reference to the accompanying drawings. As shown in fig. 1-4, a portable pilfer pendulum, including base 1, evenly open on the base has a plurality of holding tank 2, it has scalable stand 3 to articulate respectively in the holding tank, and scalable stand divide into several sections, is similar to the antenna structure, reduces the back, can put into the holding tank after turning an angle with scalable stand the central point of base one side puts and is equipped with rectangular groove 4, rectangular inslot articulates there is flexible stand 5 of cycloid, and the structure of flexible stand of cycloid is the same with the structure of scalable stand, just will be longer than the length that scalable stand stretches out, also can put into rectangular inslot after reducing, the top of the flexible stand of cycloid is fixed with crossbeam 6, the crossbeam end is connected with 7 one end of cycloid, the cycloid other end is connected with pendulum ball 8. The length of the accommodating groove is the same as the length of the telescopic upright post after being reduced, and the length of the long groove is the same as the length of the white line after being contracted.

When in use, all the upright posts are vertically pulled open to demonstrate the pilgrimage phenomenon (the vision delay of the dark lens to human eyes)

When the device is not used, all the upright posts are retracted and placed in the grooves, and the small balls and the cycloid are also placed in corresponding holes on the plate, so that the device is convenient to carry.

When the telescopic upright column in the device is retracted, the telescopic upright column is placed into the accommodating groove, and the small balls and the cycloid are also placed into corresponding holes on the plate, so that the device is convenient to carry, the volume and the weight of the device are greatly reduced, and the price of the device is greatly reduced; simultaneously, this application simple structure, easy and simple to handle, the practicality is strong, is fit for being used for the physics teaching of middle school and university, also is suitable for the show in science and technology museum.

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.
