First eyeglass 3 includes the first noumenon 31 and extends what is formed from the image side surface of the first noumenon 31 towards image side direction Extension 35.

The first noumenon 31 is contained in the collecting with the extension 35 formation receiving space 4, second eyeglass 5 Space 4 is simultaneously abutted with the extension 35, and the 3rd eyeglass 7 is accommodated in the collecting close to the side of second eyeglass 5 Space 4.

Referring to Fig. 2, being the structural representation of the first eyeglass shown in Fig. 1.The first noumenon 31 includes the first optics Portion 311 and the first supporting part 313 set around first optical section 311, the extension 35 is from first supporting part The edge of 313 image side surfaces is formed towards the extension of image side direction.

Anti-dazzling screen 9 described in sandwiched between first supporting part 313 and second eyeglass 5.Certainly, also may be used between the two So that anti-dazzling screen need not be installed, melanism material is coated on both contact surfaces, makes the image side surface of first supporting part 313 Abutted against with the thing side of second eyeglass 5.

The direction of the interior side of thing without leave to the image side of the extension 35 keeps constant or gradually increased.

The extension 35 includes the inner surface 351 and the inner surface 351 coordinated with the end face of second eyeglass 5 Relative outer surface 353 and the bottom surface 355 of the connection inner surface 351 and the outer surface 353.

The inner surface 351 is inclined-plane, and the angle formed between the inner surface 351 and optical axis is more than or equal to 0 ° and is less than 90°。

Referring to Fig. 3, the structural representation of the 3rd eyeglass shown in Fig. 1；3rd eyeglass 7 includes the 3rd optical section 71 And the 3rd supporting part 73 set around the 3rd optical section 71, thing of the 3rd eyeglass 7 from the 3rd supporting part 73 Side faces away from the direction of the second eyeglass 5 and is recessed the resigning portion 75 to be formed and avoid the extension 35.

The resigning portion 75 is recessed to be formed from the edge of the 3rd supporting part 73 towards optical axis direction, it include with it is described The first bearing and leaning portion 751 that bottom surface 355 is abutted against and the second bearing and leaning portion 753 leant with the inner surface 351.

Anti-dazzling screen 9 described in sandwiched between 3rd supporting part 73 and second eyeglass 5.Certainly, between the two can be with Anti-dazzling screen need not be installed, i.e., the thing side of described 3rd supporting part 73 and the image side surface of second eyeglass 5 are abutted against.

First eyeglass 3, second eyeglass 5 and the 3rd eyeglass 7 make three pieces of eyeglasses by such a fit system Between eccentric stability improve, and the stability of assembling is improved, so as to improve the imaging product of the imaging lens 100 Matter.

Embodiment two

Referring to Fig. 4, the structural representation of the embodiment two of the imaging lens provided for the utility model.Embodiment two with The structure of embodiment one is identical, and its difference is：

3rd eyeglass 7a, the second eyeglass 5a and the first eyeglass 3a stack gradually setting along thing side to image side direction.

The first eyeglass 3a includes the first noumenon 31a and from the thing of the first noumenon 31a side towards thing side to prolonging Stretching the extension 35a, the first noumenon 31a to be formed includes the first optical section 311a and is set around the first optical section 311a The first the supporting part 313a, the first eyeglass 3a put is from the thing of the first supporting part 313a side towards the second eyeglass 5a directions Extend the extension 35a formed.

The 3rd eyeglass 7a includes the 3rd optical section 71a, the 3rd supporting part set around the 3rd optical section 71a 73a, the 3rd eyeglass 7a from the 3rd supporting part 73a image side face away from the second eyeglass 5a directions and are recessed to be formed Avoid the one end of the resigning portion 75a, the extension 35a of the extension 35a away from the first supporting part 313a with it is described Resigning portion 75a is abutted.

Certainly, in addition to embodiment one and embodiment two, in other embodiments, the imaging lens 100 can also include Multiple first eyeglasses 3, second eyeglass 5 and the 3rd eyeglass 7 are stacked with, to first eyeglass 3, described Two eyeglasses 5 and the 3rd eyeglass 7 are only intended to the title of difference herein, when having the 4th eyeglass, the 5th eyeglass and the 6th mirror , can be according to such a fit system by the way that three eyeglasses being disposed adjacent are fixed during piece.

Moreover, wherein second eyeglass 5 can be polylith mirrors more than two pieces of eyeglasses or two pieces of eyeglasses Piece is constituted, and more than three eyeglasses being disposed adjacent can be fixed according to such a fit system.

Compared with correlation technique, the first eyeglass 3 that the imaging lens 100 that the utility model is provided include stacking gradually, the Two eyeglasses 5 and the 3rd eyeglass 7, first eyeglass 3 include the first noumenon 31 and from the first noumenon 31 towards second mirror The direction of piece 5 extends the extension 37 to be formed, and the 3rd eyeglass 7 to form avoidance institute towards being recessed away from the direction of the second eyeglass 5 State the resigning portion 75 of extension 37, by the way that second eyeglass 5 is abutted with the extension 37, and by the extension 37 with The resigning portion 75 is abutted so that the extension 37 of first eyeglass 3 respectively with second eyeglass 5, the described 3rd Eyeglass 7, which is abutted, to be coordinated, and the bias between polylith eyeglass and the stability of assembling is improved, so as to effectively raise the imaging The image quality of camera lens 100.

Above-described is only embodiment of the present utility model, it should be noted here that for the ordinary skill of this area For personnel, on the premise of the utility model creation design is not departed from, improvement can also be made, but these belong to this practicality New protection domain.
