Description

Newton pendulum ball

Technical Field

The utility model relates to a desktop presentation device, especially a Newton's pendulum ball.

Background

Newton's pendulum ball is often used for demonstrating the experiment of conservation of momentum, several spheroids in the apparatus are hung through the lifting rope that the end fixedly connects with support of both sides separately, arrange closely each other between the spheroids, and all spheroids must be on the collinear alignment, so the requirement for fixed precision of the lifting rope is very high; the existing conventional manufacturing method is that a groove is formed in the corresponding position of a support, then a lifting rope is wound in the groove for several circles, the lifting rope is adjusted to a proper length to enable all spheres to be identical in height and to be located in a straight line, and then the lifting rope is fixed in the groove by glue.

Disclosure of Invention

The utility model aims to solve the technical problem that a newton pendulum ball that the manufacturing process is comparatively quick and conveniently adjust lifting rope length is provided.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a Newton's pendulum ball, is in including base, parallel arrangement the support of base both sides and a plurality of front and back closely arrange the spheroid, the spheroid hang the setting through the lifting rope and be located both sides the support between, two tip of lifting rope respectively with be located different sides the leg joint, the support on evenly be provided with along the fore-and-aft direction with the pinhole that spheroidal transverse position and quantity correspond, the pinhole in detachable fastening insert and be equipped with the fixed pin, the fixed pin run through along the axial and be provided with the perforation, the lifting rope pass the perforation after the bend stretch into and press from both sides tightly in the lateral wall of fixed pin with the pore wall of pinhole between, the lifting rope around establishing and tying up tightly be in the lateral wall of fixed pin on.

The fixed pin interference fit insert locate the pinhole in, the lateral wall of fixed pin be provided with the guide way and establish the groove around, the lifting rope pass the perforation back edge the guide way buckle and stretch into around establishing the inslot, the lifting rope stretch into the part of guide way press from both sides tightly in the tank bottom of guide way with the pore wall of pinhole between, the lifting rope stretch into around establishing the inslot the part around establishing the inslot establish tightly in around establishing the inslot. The operation is more convenient, and other conventional fastening modes can be adopted to realize the detachable fastening connection of the fixing pin and the pin hole.

The ball body is provided with a suspension block, the suspension block is provided with a suspension hole, and the lifting rope penetrates through the suspension hole. The suspension block has a certain length, is convenient to install the ball body, is relatively firm in connection and has long service life.

Compared with the prior art, the utility model has the advantages that firstly, the ball body is hung on the lifting rope, the two ends of the lifting rope are respectively passed through the through holes of the fixed pins, the ball body is bent, stretched and wound on the side wall of the fixed pins and tightly tied, then the fixed pins are tightly inserted into the pin holes, the lifting rope is tightly clamped between the side wall of the fixed pins and the hole wall of the pin holes at the moment, the fixed installation of the lifting rope is realized, when the height of the ball body is found to be inconsistent after the ball body is installed, only the fixed pins are required to be pulled out to adjust the hanging length of the lifting rope, the rest part of the lifting rope is continuously wound on the side wall of the fixed pins and then is continuously inserted into the pin holes, the quick adjustment of the height of the ball body can be realized, finally, after a plurality of adjustments, all the ball bodies are positioned on the same height, the manufacturing process is relatively quick, the length adjustment of the lifting rope is convenient, and a user can also freely adjust to observe other phenomena; because the ball body is hung on the lifting rope and the lifting rope can be conveniently detached, the ball body can be detached and replaced with other suspensible ornaments or infant toys such as a small bell when needed, and then the lifting rope is installed, so that various ornaments or infant sounding toys can be manufactured by DIY, the functions can be expanded, the application range is greatly expanded, the product sales volume is effectively increased, and the idle rate is reduced.
