The specific embodiment
are done further detailed explanation below in conjunction with concrete embodiment to this utility model, but are not limited to these embodiment.
" preceding " described in
this description refers to " left side " side among Fig. 2, and described " back " refers to " right side " side among Fig. 2.
are with reference to Fig. 2,3 and 4; According to the auriscope of present embodiment, comprise pedestal 1, be arranged on magnifier 2, lighting source 3, the support bar 6 on pedestal 1 top; The observation base 4 that the bottom is connected with support bar 6; And be arranged on and peep ear device 5 on the observation base 4, wherein, the optical axis of magnifier 2 coincides with the central shaft of peeping ear device 5; The observer can observe through magnifier 2 and peep the ear's image in the ear device 5, is parallel to each other between the optical axis of support bar 6, lighting source 3 and magnifier 2.
are according to present embodiment; The bottom of observation base 4 inwardly offers the first axial connecting hole 40; One end of support bar 6 is arranged on the pedestal 1; The other end can be plugged in first connecting hole 40 slidably, and the axial line of support bar 6 overlaps with the axial line of first connecting hole 40.Also offering axial second connecting hole, 60, the second connecting holes 60 on the end in first connecting hole 40 being plugged in of support bar 6 communicates with first connecting hole 40.This auriscope also comprises the threaded fastener 7 that is used for fixing observation base 4 and support bar 6; Threaded fastener 7 is that an end is provided with the nut that screw thread, the other end are provided with first protuberance 70 of its inner surface of protrusion in this example; The end with screw thread of this nut is threaded with the outer wall of first connecting hole 40 mutually; Support bar 6 has second protuberance 61 of its outer surface of protrusion, and is arranged with spacing collar 9 outside the support bar 6, and first protuberance 70 of nut promptly is stuck between the spacing collar 9 and second protuberance 61.And first protuberance 70 and second protuberance 61 offset with spacing collar 9 front and back, make this nut to rotate with respect to support bar 6, and can't take place axially to move.
in addition; Between observation base 4 and support bar 6, also be provided with an elastic component 8 in the present embodiment; It is stage clip; One end of this stage clip is against on the bottom surface of first connecting hole 40, and the other end is against on the bottom surface of second connecting hole 60, and the movement tendency that makes support bar 6 have with respect to observation base 4 outwards to deviate from from first connecting hole 40.The effect of this stage clip is a thread pitch of eliminating the screw thread contact portion of observation base 4 and threaded fastener 7 (being nut); Make between screw thread and the screw thread and closely offset; Can only rotate between nut and the observation base 4; And can not take place axial looseningly, and then make when regulating diopter more stable and accurate through screw thread rotation.
In
present embodiment; The axially extended groove W1 along support bar 6 has also been offered in the outside of support bar 6; And groove W1 terminates in the place ahead of spacing collar 9, is provided with the tenon M1 that also can move forward and backward along the length direction of groove W1 with the corresponding cooperation of groove W1 in first connecting hole 40.Groove W1 and with it the setting of the tenon M1 of corresponding matching can play guide effect; Make the observer between support bar 6 and the observation base 4 axial moving forward and backward can only take place when regulating carrying out diopter through nut rotation; Can not produce rotation or non axial departing from; And then the optical axis that makes magnifier 2 is stable with the concentricity of the central shaft of peeping ear device 5, not susceptible to.
The operation principle of the auriscope of
present embodiment is: lighting source 3 illuminates ear's image of peeping ear device 5 small bore end; This image is positioned near the focal plane of magnifier 2; The observer is through magnifier 2 pictures with the aid of pictures; Therefore different observers' diopter is different, needs to regulate magnifier 2 and the distance of peeping between the ear device 5 obtains distinct image, and this distance can or be revolved through precession and moved back threaded fastener 7 (being nut) and regulate.When swivel nut, axial moving forward and backward takes place with respect to support bar 6 in observation base 4, thereby the ear device 5 of peeping on the observation base 4 is changed with respect to the distance of magnifier 2, thereby can realize the diopter of magnifier 2 is regulated.In the present embodiment; Axial moving forward and backward can take place with respect to support bar 6 in observation base 4; Elastic component 8 (being stage clip) can be eliminated the thread pitch between observation base 4 and the nut; Make and can not take place axial looseningly between support bar 6 and the observation base 4, and the groove W1 on the support bar 6 cooperates with tenon M1 on the observation base 4 and plays guide effect, support bar 6 can not produced with respect to observation base 4 rotate or non axial departing from; This makes the auriscope of present embodiment not only can realize the continuous stepless adjusting of diopter; Also make the observer can obtain more reliable, clear and ear's image accurately; And diopter need not append locking after being transferred to the position, makes the use of auriscope more quick and convenient.
are as shown in Figure 4; The difference of the auriscope of the auriscope of present embodiment and embodiment 1 is: (they are oppositely arranged on the circumference of first connecting hole 40 to have offered axially extended two groove W2 along first connecting hole 40 in first connecting hole 40; 180 ° of distances); The outer setting of support bar 6 with the corresponding cooperation of groove W2 and can move forward and backward along the length direction of groove W2 two pin M2; Groove W2 and with it the pin M2 of corresponding matching equally also play the guiding role; Make the observer between support bar 6 and the observation base 4 axial moving forward and backward can only take place when regulating carrying out diopter through nut rotation, can not produce rotation or non axial departing from.Other part of auriscope is identical with embodiment 1 in this example.
are as shown in Figure 5; The difference of the auriscope of the auriscope of present embodiment and embodiment 1 is: elastic component 8 is extension spring; The two ends of this extension spring are fixing through two steady pins 80 that are separately positioned on first connecting hole 40 and second connecting hole, 60 bottom surfaces; Observation base 4 is strained with support bar 6 mutually, and its effect is to eliminate thread pitch equally, makes between support bar 6 and the observation base 4 before and after carrying out through the nut rotation can not taking place when diopter is regulated to become flexible.Other part of auriscope is identical with embodiment 1 in this example.
More than this utility model has been done detailed description; Its purpose is to let the personage that is familiar with this art can understand the content of this utility model and implements; Can not limit the protection domain of this utility model with this; All equivalences of doing according to the spirit of this utility model change or modify, and all should be encompassed in the protection domain of this utility model
