Embodiment 1

[0024] refer to figure 2 , 3 And 4, according to the otoscope of present embodiment, comprise base 1, the magnifying glass 2 that is arranged on base 1 top, illumination source 3, support bar 6, the observation base 4 that bottom is connected with support bar 6, and be arranged on The ear speculum 5 on the observation seat 4, wherein the optical axis of the magnifying glass 2 coincides with the central axis of the ear speculum 5, the observer can observe the ear image in the ear speculum 5 through the magnifying glass 2, the support rod 6, the lighting The optical axes of the light source 3 and the magnifying glass 2 are parallel to each other.

[0025] According to this embodiment, the lower part of the viewing base 4 is provided with an axial first connecting hole 40 inwardly, one end of the support rod 6 is arranged on the base 1, and the other end is slidably inserted in the first connecting hole 40 and the axis of the support rod 6 coincides with the axis of the first ...

Embodiment 2

[0030] Such as Figure 4 As shown, the difference between the otoscope of this embodiment and the otoscope of Embodiment 1 is that: two grooves W2 extending along the axial direction of the first connecting hole 40 are provided in the first connecting hole 40 (they are in the The circumference of the first connecting hole 40 is oppositely arranged, the distance is 180°), and the outside of the support rod 6 is provided with two pins M2 corresponding to the groove W2 and capable of moving forward and backward along the length direction of the groove W2, the groove W2 and the The corresponding matching pin M2 also acts as a guide, so that the observer can only move back and forth axially between the support rod 6 and the observation seat 4 when the observer rotates the nut to adjust the diopter, and there will be no rotation or non-axial movement. Deviate. Other parts of the otoscope are the same as in Embodiment 1 in this example.

Embodiment 3

[0032] Such as Figure 5As shown, the difference between the otoscope of this embodiment and the otoscope of Embodiment 1 is that the elastic member 8 is a tension spring, and the two ends of the tension spring are respectively arranged in the first connection hole 40 and the second connection hole. The two fixed pins 80 on the bottom surface of the hole 60 are fixed to tighten the observation seat 4 and the support rod 6, and its function is to eliminate the thread gap, so that when the diopter is adjusted by rotating the nut between the support rod 6 and the observation seat 4 No back and forth loosening will occur. Other parts of the otoscope are the same as in Embodiment 1 in this example.

Abstract

The invention relates to a medical otoscope. The medical otoscope comprises a base, magnifying glass, an illumination light source, a support bar, an observation seat and an ear speculum, wherein a first connecting hole is arranged at the lower part of the observation seat, the axial lead of the first connecting hole is overlapped with the axial lead of the support bar, one end of the support barcan be slidingly inserted in the first connecting hole, and the part at which the observation seat is connected with the support bar is fixed with a threaded fastener. In the medical otoscope provided by the invention, since the support bar can be slidingly inserted into the first connecting hole, the continuous stepless regulation of the viewing angle of the otoscope can be realized and the regulation of the viewing angle is more accurate, compared with the structure in the prior art, in which the viewing angle can only be regulated by one thread pitch or more thread pitches between the observation seat and the support bar. Meanwhile, when the viewing angle is regulated, the observation seat needs not to be rotated, and the support bar can be moved back and forth only by rotating the threaded fastener; and after the regulation of the viewing angle is completed, further locking is not needed, so that the operation of the viewing angle regulation is more convenient and rapid.

Description

technical field [0001] The invention relates to a medical otoscope for checking and diagnosing ear diseases, in particular to a diopter adjustment mechanism of the otoscope. Background technique [0002] The medical otoscope uses the magnifying glass installed on the otoscope to magnify the image of the ear to facilitate the doctor's inspection. During the inspection, the doctor needs to adjust the diopter of the magnifying glass. The otoscope in the prior art mainly adopts the diopter adjustment mechanism of screw connection, and the diopter of the doctor is adjusted by rotating the nut. Such as figure 1 , the existing otoscope includes a magnifying glass A, an observation seat B, a nut C, a support rod D, an ear speculum E and an illumination light source F, the observation seat B and the support rod D are threadedly connected, and the nut C is arranged on the support rod D When using the outside of the threaded connection, the doctor uses the magnifying glass A to obser...
