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 structure of the present utility model is described Think, be all explanatory and exemplary, should not be construed as this utility model embodiment and the limit of this utility model scope System.In addition to the embodiment recorded at this, those skilled in the art can also be based on the application claims and description institute Disclosure uses other technical scheme obvious, and these technical schemes include using the embodiment recorded at this The technical scheme making any obvious substitutions and modifications.

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 mutually closes System.Note that the structure of each parts for the ease of clearly showing this utility model embodiment, between each accompanying drawing also Do not draw according to identical ratio.Identical reference marker is used for representing identical part.

Camera lens module 1 described in the utility model, it includes barrel 10, is arranged in barrel 10 between the upper and lower every setting The 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 It is arranged at the stopper 40 with fixing described second lens below described second lens 22.

Described barrel 10 includes the first barrel 11 that horizontal direction extends, bends downwards extension from described first barrel 11 The second barrel 12 and enclosed the receiving space 13 being set as, described first barrel by described first barrel 11 and the second barrel 12 11 are 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 It is positioned at same straight line with the central shaft of the optical axis of the second lens 22 Yu described barrel 10.Described first lens 21 include One optical surface 211 and be arranged at the first periphery 212 of described first optical surface 211 surrounding, described second lens 2 include Second optical surface 221 and be arranged at the second week edge 222 of described second optical surface 221 surrounding.

Adjustment unit 30 is arranged at the first periphery 212 and second week edge 222 of the second lens 22 of the first lens 21 Between, described adjustment unit 30 includes a brake sack 31 and a dark slide 32, described brake sack 31 and dark slide 32 are hollow annular structure, and the internal diameter of described brake sack 31 is less than the internal diameter of described dark slide 32, described brake sack 31 Thickness less than the thickness of described dark slide 32.As shown in Figures 1 and 2, during Fig. 2 gives Fig. 1 about part A it is The close-up schematic view of adjustment unit, in first embodiment of the present utility model, described brake sack 31 is installed on described The top of dark slide 32, as shown in Figure 3 and Figure 4, Fig. 4 gives in Fig. 3 about the part B i.e. local of adjustment unit Enlarged diagram, in the second embodiment of the present utility model, described brake sack 31 ' is installed under described dark slide 32 ' Side.Described brake sack 31 can absorb veiling glare, and described dark slide 32 has the effect being in the light, meanwhile, dark slide 22 The light reflected also can be blocked sheet 31 and absorb.Additionally, when lens molding it is difficult to ensure that the thickness of each lens is homogeneous, Therefore, when the lens thickness installed to barrel 10 is relatively thin, the relatively thick adjustment unit of thickness 30 can be selected Coordinated, on the contrary, when the lens thickness installed to barrel 10 is thicker, the tune that thickness is relatively thin can be selected Whole unit 30 is coordinated, the problem that lens edge thickness that so can be convenient, flexible is uneven.It is pointed out that Described brake sack can be punching press brake sack, and described dark slide can be plastic cement/metal dark slide.
