Abstract

Przedmiotem zgłoszenia jest rura Kundta przeznaczona do badania drgań i wizualizacji mechanicznej fali stojącej, mająca zastosowanie w laboratoriach naukowych, zwłaszcza fizycznych oraz do celów edukacyjnych. Rura Kundta zawiera rurę (1) szklaną umieszczoną poziomo na dwóch wspornikach (2), znajdujących się na końcach rury (1) i mających kształt prostokątnych, pionowo ustawionych płyt z otworami, przez które przechodzi rura (1). Dolne końce wsporników (2) są połączone na wcisk z podstawą (4), mającą kształt prostokątnej, poziomo umieszczonej płyty (4). Jeden z końców rury (1) jest zamknięty zatyczką naprężacza w kształcie walca z kołnierzem, przyklejoną do tego końca rury (1) oraz zaopatrzoną w dwa przelotowe otwory i przez każdy z tych otworów przechodzi jedna ze stalowych strun (6) albo (7), umieszczonych wewnątrz rury (1) w płaszczyźnie pionowej i skierowanych równolegle do osi rury (1). Zatyczka naprężacza jest zaopatrzona w gwint zewnętrzny, na który jest wkręcane cylindryczne pokrętło (8) z gwintem wewnętrznym i radełkowaną powierzchnią zewnętrzną. W pokrętle (8) znajduje się cylindryczny uchwyt z kołnierzem umieszczonym wewnątrz pokrętła (8) i z dwoma przelotowymi otworami, przez które przechodzą końce strun (6, 7). Końce strun (6, 7), wystające z otworów uchwytu są połączone galwanicznie mosiężną zworą. Przeciwległy koniec rury (1) jest zamknięty zatyczką wejściową w kształcie walca z kołnierzem, przyklejoną do tego końca rury (1) i zaopatrzoną w dwa przelotowe otwory.The subject of the application is a Kundt tube intended for testing vibrations and visualization of mechanical standing waves, used in scientific laboratories, especially physical ones, and for educational purposes. The Kundt tube contains a glass tube (1) placed horizontally on two supports (2), located at the ends of the tube (1) and having the shape of rectangular, vertically placed plates with holes through which the tube (1) passes. The lower ends of the brackets (2) are press-fitted to the base (4), which has the shape of a rectangular, horizontally placed plate (4). One of the ends of the pipe (1) is closed with a tension plug in the shape of a cylinder with a collar, glued to this end of the pipe (1) and equipped with two through holes, and one of the steel strings (6) or (7) passes through each of these holes, placed inside the pipe (1) in a vertical plane and directed parallel to the axis of the pipe (1). The tension plug is equipped with an external thread on which a cylindrical knob (8) with internal thread and a knurled external surface is screwed. The knob (8) has a cylindrical handle with a collar located inside the knob (8) and two through holes through which the ends of the strings (6, 7) pass. The ends of the strings (6, 7), protruding from the handle holes, are galvanically connected with a brass armature. The opposite end of the pipe (1) is closed with a cylindrical input plug with a collar, glued to this end of the pipe (1) and provided with two through holes.
