To achieve these goals, the technical solution of the utility model is as follows, and the syndeton of a kind of ear plug of stethoscope and ear-hang parts, is characterized in that, described syndeton comprises ear-hang pipe and earplug, and described earplug set is contained on ear-hang pipe.Whole technical scheme compact conformation, good airproof performance, cost is low.
Improve as one of the present utility model, described earplug one end is provided with counterbore, the other end is provided with the de-step of resistance, during assembling, whole earplug is directly sleeved on ear-hang pipe, and counterbore coordinates with ear-hang pipe, the assembling of earplug and ear-hang pipe, carry out hard-pressed bale ear-hang pipe by the tension force of earplug self, make its sealing effectiveness good, and difficult drop-off.
Improve as one of the present utility model, between described counterbore and the de-step of resistance, be provided with aperture.Sound directly enters earplug inner chamber through the aperture of earplug by the endoporus of ear-hang pipe, then the ear of people is entered, this technical scheme eliminates old metal earplug inner core, ear-hang pipe eliminates screw thread, decreases this procedure of screw thread, both improve production efficiency, reduce cost, additionally reduce the decay of sound, improve the definition of sound, further increase the auscultation effect of doctor.
Improve as one of the present utility model, the port of described ear-hang pipe is provided with chamfering.Arranging chamfering makes earplug not easily be scraped off.
Improve as one of the present utility model, described counterbore, aperture are all set to stepped.Make ear-hang pipe can not file brokenly soft earplug 5 and hurt ear like this, and play spacing effect when assembling.
Improve as one of the present utility model, the resistance of described earplug takes off step center and is provided with through hole.
Improve as one of the present utility model, the surrounding that described resistance takes off step arranges groove B, arranges the soft comfortable degree adding earplug like this, meets the requirement of human engineering, improve comfort level.
Improve as one of the present utility model, described earplug adopts elastomeric material, as silica gel material.The elasticity of silica gel earplugs is better, be conducive to assembling, and material is partially soft, to a kind of comfortable experience of wearer.
Relative to prior art, advantage of the present utility model is as follows: 1) this utility model overall construction design is ingenious, and compact conformation is practical; 2) this technical scheme carrys out hard-pressed bale ear-hang pipe by the tension force of earplug self, make its sealing effectiveness good, and difficult drop-off, 3) in this technical scheme, sound directly enters through the aperture of earplug the ear that then earplug inner chamber enters people by the endoporus of ear-hang pipe, this technical scheme eliminates existing metal earplug inner core, ear-hang pipe eliminates screw thread, decrease this procedure of screw thread, both improve production efficiency, reduce cost, additionally reduce the decay of sound, improve the definition of sound, further increase the auscultation effect of doctor; 4) counterbore in this technical scheme, aperture are set to stepped, make ear-hang pipe can not file brokenly soft earplug and hurt ear like this, and play spacing effect when assembling; 5) this technical scheme cost is lower, is convenient to apply on a large scale.
