Embodiment
To describe technology contents of the present utility model, the objects and the effects in detail, below in conjunction with embodiment and match somebody with somebody
Accompanying drawing is closed to be explained.
The design of the utility model most critical is：Blind hole is set on camera lens, focusing lever is connected in blind hole, is passed through
Focusing lever is operated, axial movement of the camera lens along accommodating chamber in accommodating chamber can be made.
It refer to Fig. 1, a kind of two-dimentional lens assembly that the utility model is provided, including camera lens 1 and place camera lens 1 and supply mirror
First 1 accommodating chamber 2 being axially moveable, the camera lens 1 is provided with blind hole 11, and the side wall of accommodating chamber 2 is provided with bar vertically
Shape through hole 21.
It was found from foregoing description, the beneficial effects of the utility model are：The two-dimentional lens assembly that the utility model is provided
It is that blind hole is set on camera lens, in conjunction with focusing lever, focusing lever is connected in blind hole, by operating focusing lever, camera lens can be made
Along the axial movement of accommodating chamber in accommodating chamber, and then the focus adjustment of camera lens is realized, it is convenient and swift.
Further, in addition to adjusting means, the adjusting means includes focusing lever, and one end of the focusing lever, which is located at, to hold
Receive outside chamber, the other end is connected in blind hole through through hole.
Further, the focusing lever includes screw rod 3, plectrum 4 and pin 5；The screw thread of plectrum 4 is socketed in screw rod 3
One end, the outer surface of the side wall of plectrum 4 is provided with nose bar 41, and the nose bar 41 is connected in blind hole 11 through through hole 21；Institute
Screw rod 3 is stated provided with annular groove 31；Annular groove 31 on the insertion of pin 5 screw rod 3 makes screw rod 3 axially retain motionless.
Seen from the above description, in the above-described embodiment, the annular groove inserted by pin on screw rod, may be such that and turn
During dynamic screw rod, screw rod is axially retaining motionless, and screw rod rotation can drive plectrum to move, so as to drive the nose bar on plectrum to drive
Camera lens is moved axially in accommodating chamber, realizes the focus adjustment of camera lens, convenient and swift, and degree of regulation is high, and fine setting can be achieved.
Further, the other end of the screw rod 3 is connected with focusing handle 6.
Seen from the above description, in the above-described embodiment, screw rod can be rotated by rotating focusing handle, handle and screw rod
T font structures are formed, it is convenient and laborsaving.
Further, the blind hole 11 is the annular groove that surrounding lens are set.
Seen from the above description, in the above-described embodiment, blind hole is designed as to the annular groove of surrounding lens setting,
During device for installing and adjusting, arbitrarily focusing lever can be connected, without finding blind hole position by spiral camera lens, therefore can carried significantly
Rise after the completion of installation effectiveness, and focusing, can be contacted toward injection glue in annular groove, glue with accommodating chamber side wall inner surfaces,
