In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1-6, a single-ear hanging stethoscope comprises a radio receiver 110, a sound tube 120, and an ear cap 200, wherein the radio receiver 110 is used for collecting sound, the sound tube 120 is used for conducting sound to an ear plug 300, the ear cap 200 is fitted over the ear, and the ear plug 300 is mounted in the ear cap 200. When in use, the earplug is tightly attached to the outlet of the external auditory canal, thereby preventing the traditional earplug from being plugged into the ear to cause the hearing loss of a doctor.

The ear cap 200 comprises ear muffs 210 capable of completely covering the outside of ears, the inner sides of the ear muffs 210 are inner cavities 211, sponges 410 are filled in the inner cavities 211, and the sponges 410 are used for isolating the sounds outside the ear muffs 210 on one hand and enabling a user to feel more comfortable when the user uses the ear cap on the other hand.

The earplug 300 is fixed in the sponge 410, the earplug 300 is fixedly connected with one end of the connecting rod 320, the other end of the connecting rod 320 is provided with a connecting hole 321, the connecting hole 321 is inserted into the connecting head 330 or assembled by screwing threads, the connecting head 330 is fixed at one end of the sound transmission tube 120, so that the sound obtained by the radio 110 is transmitted to the connecting head 330 and then transmitted to the earplug 300 through the connecting head 330 and the connecting rod, and the earplug 300 transmits the sound to eardrum through the ear bone, so that a user can hear the sound.

The outside of the ear muff 210 is fixed with one end of the ear hook 220, and the other end of the ear hook 220 is an open end and forms a space with the outer wall of the ear muff 210. When the ear-muff type earphone is used, the ear-muffs 210 and the head 600 can be fixed relatively by hanging the ears on the ears, and the structure of the ear-muffs type earphone can directly adopt the existing ear-muff type earphone.

Because the whole earmuffs have certain weight, if the earmuffs are worn for a long time, the ears are pressed by the ear hooks, so that the user is very uncomfortable, and the ear bones and the skin at the ears of the user are easily damaged. To this end, the applicant further designs a support sleeve 520, an insertion rod 510 is arranged at an end of the support sleeve 520, an annular groove 511 is arranged on the insertion rod 510, an insertion inclined surface 512 is arranged at an end of the insertion rod 510, the insertion rod 510 is inserted into the inner sleeve 231 and assembled and fixed therewith, the inner sleeve 231 is arranged inside the connection sleeve 230, the connection sleeve 230 is fixed at one end of the ear hook 220, the connection sleeve 230 is assembled or welded and fixed with the ear muff, a sinking groove 232 is further arranged on the inner sleeve 231, the annular groove 231 is assembled with one end of the clamping rod 240 in a clamping manner, so that the insertion rod 510 is fixed relatively in the axial direction, the other end of the clamping rod 240 is arranged in the sinking groove 232 and assembled and fixed with the limit ring 250, an end surface of the limit ring 250 is tightly attached to the elastic plate 260, the elastic plate 260 is arranged in the sinking groove 232 and has elasticity, and in this embodiment; the fixing bolt 270 passes through the elastic plate 260 and is assembled and fixed with the catch lever 240.

After the cover 520 is supported in the installation, will support the cover 520 suit at the top of the head to form the fixed force to ear muff department through supporting the cover, also greatly reduced ear-hang is to the oppression of ear, thereby improves doctor's comfort level, similar with current earphone. Of course, two ends of the supporting sleeve 520 may be provided with ear cups, and then the sound-transmitting tube 120 is led out to be connected with the earplugs of the two ear cups, which is the same as the existing binaural stethoscope.

When the plugging rod 510 needs to be taken out, the clamping rod is pulled outwards in the axial direction by the fixing bolt 270 against the elastic force of the elastic plate 260 until the clamping rod is separated from the annular groove.

Preferably, the clamping rod 240 is provided with a matching inclined surface 241 at the end where the ring groove is assembled, and when the insertion rod is inserted, the matching inclined surface 241 is matched with the insertion inclined surface 512, so that an axially outward thrust is generated on the clamping rod, the clamping rod overcomes the elastic force of the elastic plate to move outward, and until the clamping rod is right opposite to the ring groove, the elastic plate drives the clamping rod to reset through the elastic force, so that the clamping rod is assembled with the ring groove in a clamping manner.

Preferably, the elastic plate 260 is provided at both ends thereof with elastic edges 261, respectively, and the outer sides of the elastic edges 261 are provided with snap protrusions 262, and the snap protrusions 262 are snap-fitted with snap grooves 233 provided on the side walls of the sunken grooves 232, thereby relatively fixing the elastic plate 260. Specifically, in the process of installing the elastic edge 261 into the sinking groove 232, the inner wall of the sinking groove 232 contacts with the catching protrusion 262, so that the elastic edge is pressed by the catching protrusion 262 to be elastically deformed until the catching protrusion 262 faces the catching groove 233, and at this time, the elastic edge elastically drives the catching protrusion 262 to move toward the catching groove 233, so that the catching protrusion 262 is in snap-fit with the catching groove 233.

The details of the present invention are well known to those skilled in the art.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
