Description
Technical field
The utility model is related to medicine equipment, more particularly to stethoscope, specially one-time formed stethoscope head body.
Background technology
The speed conducted in the high material of density by sound is fast, it is small to decay, therefore the stethoscope head body of prior art is prepared using high density material, such as copper, titanium alloy, stainless steel, steel, kirsite.
As shown in Figure 1, No. 200920040508.9 Chinese patent, the cavity 2 for axis of rotation is drilled with listening head body 1, and insertion listening head body 1 is respectively in the first voice guide hole 41 and the second voice guide hole 42 of the both sides of cavity 2, the first voice guide hole 41 and the second voice guide hole 42 are used to the sound being collected into being conducted to user by rotating shaft；And insertion listening head body 1 is respectively in the first positioning hole 31 and the second positioning hole 32, rotating shaft of the both sides of cavity 2, the voice guide hole in rotating shaft is respectively turned on the first positioning hole 31 or the second positioning hole 32, high frequency audio or bass are listened to for switching；And the fixing hole 51 of insertion side listening head body 1, fixing hole 51 is used to dispose the alignment pin to make listening head body 1 and rotating shaft fix in the axial direction.
In the process in each hole of listening head body 1, side as drill bit drills through listening head body 1 forms the first positioning hole 31, then proceed to penetrate opposite side the second positioning hole 32 of formation that cavity 2 bores listening head body 1, because listening head body 1 is prepared for high density material, its hardness is higher so that drill bit is during running at high speed, when especially processing the second positioning hole 32, drill bit is easily offset, and causes the center of the first positioning hole 31 and the holes of the second positioning hole 32 not on an axis.
As shown in Fig. 2 the first positioning hole 31 and the second positioning hole 32 are circular hole, when steel ball 34 can coincide with the first positioning hole 31, rotating shaft 3 is turned on the first voice guide hole 41.As shown in Figure 3, when rotating shaft 3 need to such as be turned on the second voice guide hole 42, need rotating shaft 3, steel ball 34 is set to match fixation with the second positioning hole 32, but due to and the first positioning hole 31 and the holes of the second positioning hole 32 center not on an axis so that steel ball 34 can not coincide with the second voice guide hole 32 so that resistance of the rotating shaft 3 in rotation process suffered by forward and reverse is different, rotating shaft 3 is caused to rotate not smooth, rotating shaft can not be accurately positioned switching.
Secondly as listening head body 1 is prepared using high density material, in the case of same recruitment, the high cost of drilling is processed, and yield poorly.
