Embodiment
With reference to Fig. 1-Fig. 7, the utility model will be further described.
A kind of hand-held fundus camera camera lens positioning self-lock device, including alignment pin 10, alignment pin 10 include base 11
And the first projection 12 and the second projection 13 that vertical interval is arranged on base 11, the periphery sheathed spring of base 11, alignment pin
10 and spring be fixed in the groove 51 of the outer face of the collar 50 for connection lens 30 and main frame 40, the first projection 12 from
Passed through in the breach opened up on the shell of main frame 40, include the back-up ring 60 of annular, the edge breach of back-up ring 60, back-up ring 60
On the shell for abutting in main frame 40, and the first projection 12 from the breach at the edge of back-up ring 60 through it is rear it is exposed outside, the first projection
12 are arranged in the outer ring of the second projection 13, and locating slot 31, the first projection 12 are set on the end face for the camera lens 30 being connected with main frame 40
It is engaged with locating slot 31, alignment pin 10 is moved with the deformation of spring.
The utility model is by setting an alignment pin 10 and being fixed in main frame 40, in addition in the end face of camera lens 30
Upper setting locating slot 31, during assembling, hand-held camera lens 30 is put to the junction with main frame 40, camera lens 30 is rotated, alignment pin
10 base outer perimeter can follow spring that resilient movement occurs together because being arranged with spring, and camera lens 30 is rotated to alignment pin 10
When locating slot 31 on first projection 12 and camera lens 30 is engaged, the positioning and locking of camera lens 30, camera lens 30 and main frame are just realized
Just will not occur circumferential in rotary moving between 40, now can also send slight clickly sound, it was demonstrated that camera lens 30 and main frame 40 it
Between connected so that the connection between camera lens 30 and main frame 40 is more firm.When needing to pull down camera lens 30, pressing positioning
First projection 12 of pin 10, alignment pin 10 is moved to the first projection 12 and locating slot 31 departs from, you can pull down camera lens 30.Whole dress
Put simple in construction, the groove 51 and back-up ring 60 set on the outer face by collar 50 realizes the firm of alignment pin 10 and spring
It is fixed.
It is used as further preferred scheme：The base 11 of the alignment pin 10 includes connecting plate 111 and cylindricality fixed seat
112, the first projection 12, the second projection 13 are connected with the two ends of connecting plate 111 and are arranged in the same of the plate face of connecting plate 111 respectively
Side, fixed seat 112 are arranged in the opposite side of the plate face of connecting plate 111, and spring is set in the periphery of fixed seat 112.
