Detailed description of the invention

The embodiment recorded at this is specific detailed description of the invention of the present utility model, is used for illustrating design of the present utility model, is all explanatory and exemplary, should not be construed as this utility model embodiment and the restriction of this utility model scope.In addition to the embodiment recorded at this, those skilled in the art can also use other technical scheme obvious based on the application claims and description disclosure of that, and these technical schemes include using the technical scheme making any obvious substitutions and modifications to the embodiment recorded at this.

The accompanying drawing of this specification is schematic diagram, aids in illustrating design of the present utility model, the shape of each several part and mutual relation thereof.Note that the structure of each parts for the ease of clearly showing this utility model embodiment, do not draw according to identical ratio between each accompanying drawing.Identical reference marker is used for representing identical part.

Camera lens module 1 described in the utility model, it includes barrel 10, be arranged on barrel 10 in the most spaced first lens 21 and the second lens 22, the adjustment unit 30 being arranged between the first lens 21 and the second lens 22 and be arranged at the stopper 40 below described second lens 22.

Described barrel 10 includes the first barrel 11, the second barrel 12 bending downwards extension from described first barrel 11 that horizontal direction extends and is enclosed, by described first barrel 11 and the second barrel 12, the receiving space 13 being set as, and described first barrel 11 is provided with the light hole 111 connected with described receiving space 13.

First lens 21 and the second lens 22 are contained in the receiving space 13 of described barrel 10, and the first lens 21 and the optical axis of the second lens 22 are positioned at same straight line with the central shaft of described barrel 10.Described first lens 21 include the first optical surface 211 and are arranged at the first periphery 212 of described first optical surface 211 surrounding, and described second lens 2 include the second optical surface 221 and are arranged at the second week edge 222 of described second optical surface 221 surrounding.

Adjustment unit 30 is arranged between the first periphery 212 and the second week edge 222 of the second lens 22 of the first lens 21, described adjustment unit 30 includes brake sack the 31, first dark slide 32 and the second dark slide 33, the internal diameter of described brake sack 31 is less than described dark slide 32, the internal diameter of 33, the thickness of described brake sack 31 is less than the thickness of described dark slide 32,33.
