As a modification of the present invention, described convex tendon is arranged in sealing ring around, described convex tendon and the hole wall close contact of listening bar, and the magnitude of interference is 0.05-0.15mm, preferably 0.1mm.Adopt the hermetically-sealed construction of the connected mode of interference fit can guarantee can and the sealing of listening bar, in the time listening bar to rotate switching sound channel, the problem of having avoided stethoscope gas leakage or having leaked sound.
As a modification of the present invention, described in listen and on bar, be provided with the draw-in groove being used in conjunction with projection.The effect of playing accurate location is installed in draw-in groove and protruding cooperation, prevents that sealing ring from skidding and stopping up sound channel in the time listening bar rotation, and further guarantees sealing ring and listen being tightly connected of bar.
As a modification of the present invention, described in listen the step being provided with on bar with sealing ring medial wall interference fit, the arranging of this step guaranteed the sealing of listening bar to be connected with sealing ring.
As a modification of the present invention, described in listen and on bar, be provided with through hole, described in listen the through hole on through hole and the sealing ring on bar to be used in conjunction with, keep unimpeded.
As a modification 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 in often switching is not easy to wear, further keeps sealing effectiveness.
As a modification 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, make can, listen between bar and can not produce Lou sound and gas leakage at acoustic hole during at acoustic by special inside and outside portion structural design, thereby avoid the too much decay of sound in acoustic process, increase loudness, thereby improve stethoscopic performance, provide reliable foundation for medical personnel make pathological analysis accurately.
