Outside is provided with the first lens, and the other end of the cylinder is internal thread segment, is provided on the inner peripheral surface of the internal thread segment
Internal thread is provided with external screw thread on the outer circumference surface of the screwed pipe, and the screwed pipe stretches into the internal thread segment, the spiral shell
Line pipe is connected through a screw thread with the internal thread segment, and second that radially protruding is provided on one end inner wall of the screwed pipe is convex
Edge, described state are provided with the second lens on the outside of the second flange, first lens and the second lens are coaxial.
In a preferred embodiment of the present invention, the other end of the screwed pipe is provided with the portion of screwing.
The beneficial effects of the invention are as follows：The lens distance regulating mechanism of the present invention is for installing two lens, and two
The distance between lens can be adjusted.
Description of the drawings
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other
Attached drawing, wherein：
Fig. 1 is the structural schematic diagram of the lens distance regulating mechanism of the present invention.
The label of each component is as follows in attached drawing：1, the first lens, the 2, first flange, 3, cylinder, 4, internal thread segment, 5, screw thread
Pipe, the 6, second lens, the 7, second flange, 8, screw portion.
Specific implementation mode
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
All other embodiment that technical staff is obtained without making creative work belongs to the model that the present invention protects
It encloses.
Referring to Fig. 1, the embodiment of the present invention includes：A kind of lens distance regulating mechanism comprising cylinder 3 and screwed pipe 5,
The first flange 2 of radially protruding is provided on one end inner wall of the cylinder 3, the outside of first flange 2 is provided with first
The other end of lens 1, the cylinder 3 is internal thread segment 4, and internal thread is provided on the inner peripheral surface of the internal thread segment 4, described
External screw thread is provided on the outer circumference surface of screwed pipe 5, the screwed pipe 5 stretches into the internal thread segment 4, the screwed pipe 5 with
Internal thread segment 4 is connected through a screw thread, and the second flange 7 of radially protruding is provided on one end inner wall of the screwed pipe 5, described to state
The outside of second flange 7 is provided with the second lens 6, and first lens, 1 and second lens 6 are coaxial.
The fixation of first lens 1 is pasted onto on the lateral surface of the first flange 2, and the fixation of the second lens 6 is pasted onto the second flange 7
On lateral surface, the position of the first lens 1 is fixed, and rotation, which screws portion 8, makes screwed pipe 5 rotate, before screwed pipe 5 is in internal thread segment 4
Into or retreat, to change the distance between the second lens 6 and the first lens 1, and this distance adjust easily very accurately.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
