In a specific embodiment of the present invention, the lens barrel mounting base 1 belongs to imaging mechanism, it is spiral shell in a band first
Line and the 4th externally threaded mounting base for assembling lens assembly 5, first internal thread is first auxiliary section, described
4th external screw thread is the 4th auxiliary section, and the lens barrel mounting base 1 further includes the first location structure, the first positioning knot
Structure includes banking pin 4, and in this embodiment, which is connected to lens barrel mounting base 1 by spiral way, will be spacing
Nail 4 is regarded as with the lens barrel mounting base 1 to be integrated, and first location structure further includes first boss wall.
The resilient latching member 2 is that a periphery is all round table surface and its front and back end marginal belt is jagged, can be sent out after stress
Raw elastically-deformable thin-walled workpiece, does not limit its specific material, it is desirable to which energy elastic deformation, the resilient latching member 2 is also
Including with matched second location structure of the first location structure, and second location structure further includes and 4 phase of banking pin
The limit hole of mating, the limit hole are two or more in notch, and second location structure further includes and described first
The matched second boss wall of boss wall.
The camera lens lock sleeve 3 is feature lock sleeve, on the one hand its inner surface is fixed on institute using thread forms
State the front end face of lens barrel mounting base 1, i.e., described camera lens lock sleeve 3 includes the second auxiliary section, and second auxiliary section for institute
The second external screw thread that the first internal thread matches is stated, on the other hand needs and the round table surface interworking of resilient latching member 2 is so that described
Resilient latching member 2 can be locked with stress, its appearance can be designed according to global design style.
The lens assembly 5 is the body tube of the 3rd internal thread to be matched by a band with the 4th external screw thread and interior
Portion's eyeglass etc. forms, i.e., described 3rd internal thread is the 3rd auxiliary section, is a group that is replaceable, needing focal adjustment
Part.
Concrete operating principle is as follows：
Two banking pins 4 are installed in lens barrel mounting base 1, the lens barrel mounting base 1 is provided with right with the banking pin 4
The threaded hole answered, can hand twist banking pin 4 to lens barrel mounting base 1, then the banking pin 4 and the lens barrel mounting base 1 are seen
As one；Resilient latching member 2 is sleeved on banking pin 4, resilient latching member 2 is round table-like, can be sleeved on the notch of its big end
On banking pin 4, and the second boss wall is socketed on outside the first boss wall of lens barrel mounting base 1；Camera lens lock sleeve 3 is mounted in
In lens barrel mounting base 1, the second external screw thread of the inner surface of 3 one end of camera lens lock sleeve and the first internal thread of lens barrel mounting base 1 are mutual
Match somebody with somebody, 3 inner surface other parts of camera lens lock sleeve are interior round table surface, the outer round table surface interworking with the resilient latching member 2, and taper
Unanimously；Camera lens lock sleeve 3 is when screwing in lens barrel mounting base 1, it is only necessary to 1 to 2 circle screw threads are screwed in, it is spacing without being firmly screwed into
Place；Lens assembly 5 is loaded into lens barrel mounting base 1, holds primary mirror drum outer wall, screws in lens barrel mounting base 1, under the lens assembly 5
Side is provided with O-ring seals, the sealing being used between lens barrel mounting base 1, and resistance when appropriate increase lens focusing；Rotation
Index glass head assembly 5, accommodating to suitable position can stop；Revolved toward the direction turn camera lens lock sleeve 3 close to lens barrel mounting base 1
The tight camera lens lock sleeve 3, the interior round table surface of camera lens lock sleeve 3 can promote the outer round table surface of resilient latching member 2, but because elasticity
The big end of locking member 2 is spacing by lens barrel mounting base 1, and band notch above resilient latching member 2, therefore in resilient latching member 2
Wall understands deformation retract and the resilient latching member 2 will not rotate, and such resilient latching member 2 just can hold the lens assembly tightly
5, so as to limit the movement of the lens assembly 5, also it is achieved that the locking of lens assembly 5；It is opposite, if to screw out or more
Change lens assembly 5, it is only necessary to loosen camera lens lock sleeve 3, make the no longer stress deformation of resilient latching member 2, make resilient latching member 2 and mirror
Gap is produced between head assembly 5, then lens assembly 5 is screwed out into lens barrel mounting base 1 and can be achieved to screw out or replace lens assembly 5
.
This lens changeable, be easy to focus and that locks realizes mechanism and installation method, can convenient changing, focusing and lock
Tight camera lens, improves operating efficiency, will not additionally, due to the thread pitch avoided between traditional locking nut and lens assembly 5
Cause 5 optical axis direction of lens assembly to deviate, influence of the retaining mechanism to the focusing result of lens assembly 5 can be reduced, realize complete manual
Focusing, without instrument.
As it will be easily appreciated by one skilled in the art that the foregoing is merely illustrative of the preferred embodiments of the present invention, not to
The limitation present invention, all any modification, equivalent and improvement made within the spirit and principles of the invention etc., should all include
Within protection scope of the present invention.
