Description

[Detailed description of the invention] Longitudinal wave experimental device invented by the applicant
37759) vertical and transverse wave conversion hook is (a) as lightweight as possible;
(b) Same length as possible, (c) Vibration surface constant, (d) Vibration surface
In order to satisfy the following conditions: (e) it can rotate 90 degrees, (e) it has the rotational force to rotate the vibration direction of the main spring, and (f) the vibration does not stop even if it rotates 90 degrees, we suspended the main spring with a nylon thread. It was simply made into an elongated V-shape using Al foil. However, this did not provide sufficient rotational force, and rotation always required considerable skill.
That is, depending on the various main springs, there were cases in which the rotation did not occur. Also, Al foil is weak against twisting and bending deformation, but strong against tension and heat. It is extremely easy to puncture and tear due to the force of its application. Therefore, in terms of performance as well as durability, we wanted to make it easy to rotate and use it semi-permanently. As a result of various studies, the present applicant was able to easily achieve the objective by making the vertical and transverse wave conversion hook as follows. That is, the V-shaped suspended nylon thread 3 is reinforced with two, three, and nylon threads 7 as it goes toward the top. This makes it difficult to deform due to rotation and increases rotational force. Furthermore, by attaching a light and strong gauze 4 to the upper part, the rotational force was increased and at the same time it became less likely to tear. This made it possible to easily achieve the purpose with any rotation, without requiring any skill, no matter what type of main spring it was. The structure of the longitudinal and transverse wave conversion hook is shown in Figure 1. 1
is nylon thread, 2 is ring, 5 is hook, 6 is
AL foil, 8 is a support rod. This longitudinal and transverse wave conversion hook is converted into a second vertical and transverse wave conversion hook as shown in Figure 2.
Attach it to the longitudinal wave experimental apparatus as shown in the figure. The support rod 8 of the vertical and transverse wave conversion hook 3 is attached to the hook conversion body 16 suspended from the parallel rod 13 of the longitudinal wave experimental apparatus, and the hook 5 of the longitudinal and transverse wave conversion hook 3 is attached to the main spring 1 of the longitudinal wave experimental apparatus. .
