Embodiment of the present utility model is related to a kind of imaging lens 100, as shown in Figure 1-2, including with receiving space
13 lens barrel 1, and the lens set 10 for including at least one eyeglass in receiving space 13 is arranged on, lens barrel 1 is logical including offering
First barrel 11 of unthreaded hole 14, the second barrel 12 from the bending extension of the first barrel 11, the first barrel 11 and the second barrel 12 enclose
If form receiving space 13.
Imaging lens 100 also include being arranged on pressure ring 2 in receiving space 13, lens set 10 be folded in the first barrel 11 with
Between pressure ring 2, connecting portion 21 that pressure ring 2 includes abutting with the second barrel 12, from connecting portion 21 to the optical axis of close lens set 10
The flange 22 of the curved extension in 00 ' direction, flange 22 support lens set 10, and flange 22 surrounds a deep-slotted chip breaker 23 with connecting portion 21,
And deep-slotted chip breaker 23 is open and is directed away from the direction of first barrel 11.Further, the flange 22 is from the connecting portion 21
After the curved extension of optical axis direction to the close eyeglass, further towards the curved extension in image side direction so that the company
Socket part 21 forms the shape of semicircular ring with the flange 22.
Pressure ring 2 in present embodiment is provided in inside lens barrel 3, because the light outside lens barrel 1 is incident to from thing side
In lens barrel 1, and veiling glare is easily reflected to form inside lens barrel 1, in present embodiment, because pressure ring 2 includes and second
The connecting portion 21 that wall 12 abuts, the flange 22 of the curved extension in the direction of optical axis 00 ' from connecting portion 21 to close lens set 10, are turned over
Side 22 surrounds a deep-slotted chip breaker 23 with connecting portion 21, on the one hand, by the way that pressure ring 2 is arranged into connecting portion 21 and the structure of flange 22, from
And the skew wall structure of existing pressure ring 2 is instead of, lens barrel is reflexed to by the skew wall of pressure ring 2 in the prior art so as to avoid veiling glare
Image quality is influenceed in 1；Still further aspect, by setting deep-slotted chip breaker 23 on pressure ring 2, veiling glare can be caused in deep-slotted chip breaker 23
It is middle to pass through multiple reflections, so as to enhance the light absorptive of pressure ring 2, so as to weaken the veiling glare that interference is produced to imaging effect, and then
It ensure that good image quality.
It is noted that in the present embodiment, flange 22 can set flange and elliptic arc flange in the arc-shaped, separately
Outside, the radian of arc flange 22 can be 90 degree -180 degree, and technical staff can be selected according to being actually needed, herein no longer
Illustrate.
It should be noted that in the present embodiment, connecting portion 21 and flange 22 are integrally formed.It is arranged such, can simplifies
The processing and installation process of pressure ring 2, improve production and efficiency of assembling.In specific process, pressure ring 2 is using direct punching press
Mode is process, and automaticity is high.It is noted that technical staff can also use and divide according to being actually needed
Not Jia Gong connecting portion 21 and flange 22, the mode then assembled again produces pressure ring 2, no longer illustrates herein.
In addition, in present embodiment one, the pressure ring 2 is continuous cyclic structure.It is arranged such so that pressure ring 2 fills
With more convenient, raising efficiency of assembling.
Specifically, when pressure ring 2 is assembled in lens barrel 1, in the present embodiment, connecting portion 21 and flange 22 pass through
Glue is fixed with the second barrel 12, lens set 10.Specifically, first the connecting portion 21 of pressure ring 2 can be supported in the second barrel
On 12, flange 22 and the position of lens set 10 are then adjusted so that flange 22 is supported in lens set 10, then using gluing
Mode assembles pressure ring 2 in lens barrel 1, it is necessary to illustrate, in gluing procedures, unnecessary glue can penetrate into flange 22 with
The deep-slotted chip breaker 23 that connecting portion 21 surrounds, so that the fixed effect of pressure ring 2 is more preferable.Certainly, the pressure ring 2 also can by with institute
State the second barrel 12 and be interference fitted and the lens set 10 is fixed in the lens barrel 1.
It is noted that in the present embodiment, pressure ring 2 is plastic chuck ring or metal pressure ring.The structure of metal pressure ring
Intensity is more preferable, and the price of plastic chuck ring is cheaper, and technical staff can consider metal pressure ring and modeling according to being actually needed
The characteristics of expecting pressure ring selects the material of pressure ring 2, no longer illustrates herein.
It is understood that as shown in figure 1, in the present embodiment, the eyeglass in lens set 10 can be 4, also may be used
Be 2,3,5 or more, specific number, selection setting can be carried out according to different demands, in the present embodiment,
Lens set 10 includes 4 eyeglasses.
Further, in present embodiment, as shown in figure 1, imaging lens 100 also include being arranged in receiving space 13
Anti-dazzling screen 3, anti-dazzling screen 3 are located in the lens set 10 between any two adjacent mirror.Anti-dazzling screen 3 can reduce lens barrel wall 1
It is reflective, anti-dazzling screen 3 is set between each two eyeglass, it is possibility to have the intake for blocking some veiling glares of effect and in imaging lens
The reflection of first 100 internal light.In addition, imaging lens 100 also include the shadow shield 4 being arranged in receiving space 13, also, hide
Tabula rasa 4 can be folded between the adjacent eyeglass of any two, and the position of shadow shield 4 can be also configured as needed, this reality
Apply in mode, the position of shadow shield 4 is between two eyeglasses near image side, so as to further avoid veiling glare to imaging
The influence of quality.It is noted that as shown in figure 1, in present embodiment, between two adjacent mirrors near image side
The anti-dazzling screen 3 be located at the image side of the shadow shield 4, it is to be understood that the anti-dazzling screen 3 can also be located at the shadow shield
4 thing side.
As shown in Figure 3 and Figure 4, second embodiment of the present utility model is related to a kind of imaging lens 200.Fig. 3 is shown
Along the topology view of imaging lens 200 at the direction of optical axis 00 ' visual angle, Fig. 4 show the imaging lens along the direction of vertical optical axis 00 ' visual angle
First 200 topology view.The main distinction of second embodiment and first embodiment is：Pressure ring 2 is included around the eyeglass
The spaced multiple curved portions 20 of optical axis 00 ' of group 10, each curved portion 20 include a connecting portion 201 and connected certainly
The flange 202 that portion 201 extends.
By the above it is seen that, because pressure ring 2 includes spaced multiple curved portions 20, so that pressure ring
2 structure that can reflect veiling glare is reduced, so as to further avoid the reflection of veiling glare, so that image quality is more preferable.
In addition, in the present embodiment, multiple curved portions 20 can be placed equidistant, so that, the curved portion 20 of pressure ring 2
More preferable fixing len group 10, the number in curved portion 20 can be for 3,4 and more, in the present embodiment, curved portion
20 be 4, so as in the case where the fixed effect for ensureing lens set 10 is best, at utmost weaken the reflection of veiling glare, so as to
Ensure good image quality.
It will be understood by those skilled in the art that the respective embodiments described above are to realize specific implementation of the present utility model
Example, and in actual applications, can to it, various changes can be made in the form and details, without departing from spirit of the present utility model
And scope.
