Abstract
The invention relates to a part for a medical appliance, in particular to a part for a stethoscope. The invention discloses a connecting piece for the rotating shaft and listening head of a stethoscope, wherein a deformation slot is formed on the outer wall of a tubular connecting piece. In the invention, the inner wall of the connecting piece is prevented from deforming effectively when the connecting piece is mounted, so that the rotating shaft rotates more smoothly; and thus, the rejection rate is lowered, the matching precision is improved and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of fitting of medical apparatus, especially refer to a kind of stethoscopic accessory.
Background technology
As shown in Figure 1 and Figure 2, the connector of existing rotating shaft of stethoscope and can body, connector 3 is a tubulose, tubular connection 3 is provided with two dead in line through holes 4, is provided with two symmetric locating slots 5 in connector 3 one port part; During installation, earlier connector 3 is enclosed within an end of rotating shaft of stethoscope 1, one end that will package the rotating shaft of stethoscope 1 of connector 3 is again packed in the cavity 8 of can body 2, need after installing to guarantee that rotating shaft 1 can be rotated smoothly and can from the cavity 8 of can body 2, not come off that the external diameter of pipe of therefore general connector 3 is slightly larger than cavity 8 internal diameters.In installation process, connector 3 is owing to be squeezed and can deform, and prior art is that the internal diameter and the external diameter of connector 3 all deforms, and causes connector 3 bad with cooperating of rotating shaft 1, thereby influences the rotation of rotating shaft 1.
Summary of the invention
Goal of the invention of the present invention is, connector outer wall distortion when a kind of the installation is provided but deformation does not take place inwall can effectively improve the connector of rotating shaft of stethoscope rotating effect and quality of fit.
Goal of the invention of the present invention is achieved in that
The connector of a kind of rotating shaft of stethoscope and can body, described connector is a tubulose, is provided with two dead in line through holes on tubular connection, is provided with two symmetric locating slots in connector one end; On the outer wall of described tubular connection, be provided with the distortion groove.
Further: described distortion groove is a screw thread.
Further: described distortion groove is plural at least ring shaped slot.
The present invention has the following advantages:
1, effectively avoids prior art when mounted, caused the inside pipe wall distortion of connector after connector is squeezed, guaranteed the rotating shaft rotation smoothly, also guaranteed the quality of fit of rotating shaft and connector simultaneously.
2, rotating shaft of the present invention and can body be rotatably assorted more smoothly, quality of fit is higher, the acoustic better effects if.

The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing 3-9 and concrete embodiment.
Embodiment:
In conjunction with the accompanying drawings 3, Fig. 4 as can be known, the connector 3 of a kind of rotating shaft of stethoscope and can body, connector 3 is a tubulose.Tubular connection 3 is provided with two dead in line through holes 4 ', is provided with two symmetric locating slots 5 ' in connector 3 one ends.The outer wall of tubular connection 3 is provided with distortion groove 7.Distortion groove 7 is a ring shaped slot.
During installation, as can be known in conjunction with Fig. 4 to Figure 11;
Because of connector 3 fixing with cavity 8 in, and the external diameter of pipe of connector 3 is slightly larger than cavity 8 internal diameters, so after inserting cavity, connector 3 does not rotate with the can body, thereby to listen to double-tone be that the rotation of dependence rotating shaft realizes.In case rotating, rotating shaft freely will directly not influence the effect of audition.
And in the prior art, when being squeezed into cavity 8 owing to connector 3, the deflection of connector 3 can't shift, and causes the internal diameter of connector 3 and external diameter that deformation all takes place, and it is not smooth to cause rotating shaft to be rotated, thereby has influenced the effect of audition.And the present invention makes when connector 3 is squeezed into cavity 8 owing to be provided with ring shaped slot on the outer wall of connector 3, only ring shaped slot generation deformation on connector 3 outer walls, and the internal diameter of connector 3 is constant, thus better realized the purpose of audition.
Embodiment 2:
10,11 as can be known in conjunction with the accompanying drawings,
The connector 3 of a kind of rotating shaft of stethoscope and can body, connector 3 is a tubulose.Tubular connection 3 is provided with two dead in line through holes 4 ', is provided with two symmetric locating slots 5 ' in connector 3 one ends.The outer wall of tubular connection 3 is provided with distortion groove 7, and the distortion groove is a fine thread.
During installation, as can be known in conjunction with Fig. 4 to Fig. 9;
Rotating shaft 1, when treating that steel ball turns to the locating slot established on the connector 35 ' with rotating shaft 1, spring ejects steel ball and makes rotating shaft 1 location, at this moment, one of through hole 4 ' on voice guide hole 12 in the rotating shaft 1 and the connector 3 communicates, and with collection sound chamber 13 conductings of can body 2 one sides, realize leading note.
Because of connector 3 fixing with cavity 8 in, and the external diameter of pipe of connector 3 is slightly larger than cavity 8 internal diameters, so after inserting cavity, connector 3 does not rotate with the can body, thereby to listen to double-tone be that the rotation of dependence rotating shaft realizes.In case rotating, rotating shaft freely will directly not influence the effect of audition.
And in the prior art, when being squeezed into cavity 8 owing to connector 3, the deflection of connector 3 can't shift, and causes the tubulose internal diameter of connector 3 and external diameter that deformation all takes place, and it is not smooth to cause rotating shaft to be rotated, thereby has influenced the effect of audition.And the present invention makes when connector 3 is squeezed into cavity 8 owing to be provided with the distortion groove on the outer wall of connector 3, only fine thread generation deformation on connector 3 outer walls, and the internal diameter of connector 3 is constant, thus better realized the purpose of audition.
