End 12 is included as end opening 121, as the bore of end opening 121 is more than the aperture of thing end perforate 112, is formed step-like, is made lens
Group can be installed and is fixed in lens barrel.Thing end in present embodiment, be formed in one structure as end, outer portion, it is not necessary to enters
The extra assembly work of row, and can be directly obtained by way of injection moulding.
As shown in figure 3, lens group 2 comprising lens 21, anti-dazzling screen 22, annular shading element 23, retaining ring 24 and other
Some lens.Specifically, the lens 21 in present embodiment are convex lens, include ring part 211 and dome portion 212, dome
Portion 212 protrudes from ring part 211, and dome portion 212 is connected and is projected in ring part 211 with ring part 211, dome portion 212 with
Ring part 211 is integral；Wherein, ring part 211 is arranged in lens barrel 1.It should also be understood by those skilled in the art that lens 21 are also
Can be planar lens or concave lens, to realize close effect.Anti-dazzling screen 22 and annular shading element 23 can be to spurious rays
Blocked, to improve image quality.Retaining ring 24 is arranged on the lower section of lens group and is fixedly connected with lens barrel 1, to prevent
Lens group 2 departs from lens barrel 1, plays a part of fixed lens group 2.
As shown in figure 4, pressure ring part 3 is arranged in lens barrel 1 in annular shape, pressure ring part 3 includes mounting opening 31, and installation is opened
The aperture in hole 31 is more than or equal to the diameter in dome portion 212, and pressure ring part 3 is connected to lens barrel, the part of dome portion 212 by a plastic structure
Protrude from mounting opening 31.Point plastic structure is prior art, is a kind of conventional gluing means, such structure causes pressure ring part
3rd, compact conformation between lens barrel 1 and lens group 2.It is understood that approximate effect can be also realized with other connected modes,
This is not stated with tired.
As shown in figure 1, anti-dazzling screen 4 is a thin slice, it includes shading perforate 41, and the aperture of shading perforate 41 is less than or equal to convex
The diameter in circle portion 212, and less than the aperture of thing end perforate 112, anti-dazzling screen 4 is located between thing end wall 111 and pressure ring part 3, convex
The part of circle portion 212 protrudes from shading perforate 41 and part is located in thing end perforate 112.
In summary it is seen that, on the basis of existing optical lens, pressure ring part 3 is set up in lens barrel 1, and in lens barrel 1
Anti-dazzling screen 4 is set up between pressure ring part 3, pressure ring part 3 is connected on lens barrel 1 and anti-dazzling screen 4 is clamped, the setting of anti-dazzling screen 4
Effectively reduce the veiling glare of light hole.Meanwhile, more preferably, the assembling with lens group 2 coordinates the circularity of the shading perforate 41 of anti-dazzling screen 4
Effect is more preferable.
It should be noted that the inner surface of thing end wall 111 includes hierarchic structure, hierarchic structure includes first step anchor ring
113rd, connection anchor ring 114, second step anchor ring 115, connection anchor ring 114 and first step anchor ring 113 and second step anchor ring 115
Connect respectively, the central shaft of first step anchor ring 113 and second step anchor ring 115 is overlapping, the diameter of first step anchor ring 113 is small
In the diameter of second step anchor ring 115, connection anchor ring 114 is parallel with central shaft；Pressure ring part 3 is connected on connection anchor ring 114, ring
Shape portion 211 is held on second step anchor ring 115.The setting of this hierarchic structure can provide one and place pressure ring part 3 and shading
The space of piece 4.
Second embodiment of the present utility model is related to a kind of optical lens.Second embodiment is big with first embodiment
Cause is identical, is in place of the main distinction：In the first embodiment, thing end wall is structure as a whole.And in the utility model second
In embodiment, as shown in Fig. 5,6,7, thing end wall 111 is included：Mounting ring 116 and lens barrel wall 117, thing end perforate 112 are opened in
On mounting ring 116, lens barrel wall 117 includes assembling perforate 118, and mounting ring 116 is embedded in assembling perforate 118 by attachment structure
Interior, hierarchic structure is arranged on mounting ring 116.Mounting ring 116, pressure ring part 3 is so set to constitute one detachably with anti-dazzling screen 4
Structure.Because the size of shading perforate 41 of anti-dazzling screen 4 determines the size of optical lens light hole, thus different screenings can be selected
The anti-dazzling screen 4 of light perforate 41 constitutes different demountable structures.When actually used, it can be selected to close according to the size of light hole
Suitable demountable structure.
It should also be noted that, mounting ring 116 is embedded in assembling perforate 118 by attachment structure, attachment structure is included：
The first convex tendon 1161 being arranged on the lateral surface of mounting ring 116, the first groove being arranged on the assembling medial surface of perforate 118
1181.In present embodiment, mounting ring 116 is integrally formed with the first convex tendon 1161, by applying straight down to mounting ring 116
Power after, the first convex tendon 1161 just engages because of its elastic deformation with the first groove 1181, and this kind of assembling mode is more convenient.First
Convex tendon 1161 is annular in shape, it may also be said to which projection of first convex tendon 1161 at thing end is in the annular of closure, and the first groove 1181 is in
The ring-type coordinated with the first convex tendon 1161, makes the contact area of the first convex tendon 1161 and the first groove 1181 bigger, and connection is more
It is stable, it is simple in construction, it is easy to assembling.It should be understood by one skilled in the art that the shape of the first convex tendon and the first groove is simultaneously
This is not limited to, other shapes also can reach propinquity effect.In addition, the vertical tangent-plane projection semicircular in shape of the first convex tendon 1161,
Make it easier to slip into the first groove 1181.
3rd embodiment of the present utility model is related to a kind of optical lens.3rd embodiment and second embodiment are big
Cause is identical, is in place of the main distinction：In the third embodiment, the first convex tendon 1161 is set on the lateral surface of mounting ring 116,
First groove 1181 is set on the assembling medial surface of perforate 118.And in the embodiment of the utility model the 3rd, such as Fig. 9,10 institutes
Show, set on the lateral surface of mounting ring 116 and second convex tendon 1182 is set on second groove 1162, the assembling medial surface of perforate 118.Such as
Shown in Fig. 8 circled portions, i.e., where the difference of the 3rd embodiment and second embodiment.
Specifically, mounting ring 116 is integrally formed with the second groove 1162, by applying straight down to mounting ring 116
Power after, the second convex tendon 1182 just engages because of its elastic deformation with the second groove 1162, and this kind of assembling mode is more convenient.Second
Convex tendon 1182 is annular in shape, it may also be said to which projection of second convex tendon 1182 at thing end is in the annular of closure, and the second groove 1162 is in
The ring-type coordinated with the second convex tendon 1182, makes the contact area of the second convex tendon 1182 and the second groove 1162 bigger, and connection is more
It is stable, it is simple in construction, it is easy to assembling.In addition, the vertical tangent-plane projection semicircular in shape of the second convex tendon 1182, makes it easier to slip into
In second groove 1162.
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.
