As a kind of improvement of the present invention, be provided with the draw-in groove that is used in conjunction with projection on the described tin of bar.The cooperation of draw-in groove and projection is installed and to be played the effect of accurate location, prevents that sealing ring from skidding and stop up sound channel when listening the bar rotation, and further guarantees sealing ring and listen being tightly connected of bar.
As a kind of improvement of the present invention, be provided with the step with sealing ring medial wall interference fit on described tin of bar, this step the sealing that has guaranteed that tin bar is connected with sealing ring is set.
As a kind of improvement of the present invention, be provided with through hole on the described tin of bar, the through hole on described tin of bar and the through hole on the sealing ring are used in conjunction with, and keep unimpeded.
As a kind of improvement of the present invention, the material of described sealing ring is poly-fluorine material, and this material has guaranteed that double head model stethoscope sealing ring when often switching is not easy to wear, further keeps sealing effectiveness.
As a kind of improvement of the present invention, described hermetically-sealed construction is applicable on the can link of double head model stethoscope.
Sealing ring of the present invention adopts the connected mode of interference fit with listening bar and can, good sealing effect, by special inside and outside structural design so that can, listen between the bar at acoustic hole and can not produce Lou sound and gas leakage during at acoustic, thereby avoid the too much decay of sound in the acoustic process, increase loudness, thereby improve stethoscopic performance, provide reliable foundation for medical personnel make pathological analysis accurately.
