The utility model discloses a lock catch type camera lens base does not allow the prone to deviate and the operation of focusing more convenient when making the camera lens use.
Description
Technical field
This utility model is related to lens base, specifically a kind of lock catch type lens base.
Background technology
Lens base：For the mechanism member that is fixed on camera lens on imager chip it is possible to by adjusting camera lens and camera lens
Relative position between base so that lens imaging face is overlapped with imager chip, that is, is focused.
As shown in figure 1, traditional lens base 2 is typically threadedly connected with camera lens 1, and pass through threaded engagement
The position to determine camera lens for the number of turns, when lens imaging face is overlapped with the surface of imager chip, camera lens is in optimal focusing position
Put.Now it is necessary to fix camera lens with lens base relative position, to ensure camera lens and lens base during life-time service
It is relatively fixed.
In addition to screw thread, also bright finish coordinates connected mode between camera lens and lens base.But, both modes exist
After the completion of focusing, it is required for fixing the product after the completion of focusing again by way of extra, in case in life-time service process
Matching loose between middle camera lens and lens base, leads to bad, image blur of focusing.
At present, camera lens, after the completion of focusing, can be locked by most products in the side Positioning screw of lens base
Or with glue, camera lens and lens base are adhesively fixed.Although fixed easy to operate with Positioning screw, due to camera lens and mirror
Often there is certain gap between head base, after lens focusing puts in place, Positioning screw of screwing on, camera lens will tilt or toward one
Side offsets, and clearly one side of something is fuzzy or imaging surface edge has dark angle to lead to imaging surface one side of something.When being bonded with glue, also due to mirror
The presence in gap between head and lens base, the tension force that glue is formed in process of setting leads to camera lens deflection, causes imaging surface half
Side is clearly half of fuzzy.
Utility model content
This utility model, in order to overcome the deficiencies in the prior art, provides a kind of lock catch type lens base it is intended to solve tradition
Lens base use during camera lens easily offset, focus difficulty shortcoming.
In order to solve above-mentioned technical problem, the utility model proposes basic technical scheme be：
A kind of lock catch type lens base, including base body, this base body inwall is provided with female thread structure, its feature
It is, described lock catch type lens base also includes an internal diameter and base inner diameter size identical annular lock, described ring lock
Button is provided with the female thread matching with camera lens, completes to defocused, this ring lock of turn when camera lens screws in base with thread connecting mode
Button makes the upper surface of its lower surface and base body mutually extrude generation frictional force thus the position of fixed lens.
Further, described annular lock fixed lens after can click and enter glue in junction, for further fixed lens with
The position of annular lock.
Further, described annular lock side is provided with Positioning screw, for the position of further fixed lens and annular lock
Put.
The beneficial effects of the utility model are：
This utility model lens base is by setting up the position of annular lock fixed lens, the lower surface of this annular lock
Contact for whole loop with camera lens upper surface and mutually extruding produces frictional force, the position of annular lock in the presence of this frictional force
Once putting fixation would not slide easily so that will not being tilted easily or offset by the fixing camera lens of this annular lock.Additionally, adopting
With annular lock fixing mode, camera lens and lens base screw thread need not be accomplished completely the same, camera lens screw thread and mirror can be allowed
There is certain gap between head whorl of base, so on the one hand decrease camera lens (screw thread) and the difficult processing of lens base (screw thread)
Degree, improves the efficiency of production, on the other hand because allowing to loosen between camera lens and lens base, is easier, makes when turning
Obtain lens focusing more convenient to operate.

Specific embodiment
Below with reference to accompanying drawing 2 to 3 and embodiment, this utility model is described further, but should not be limited with this
Protection domain of the present utility model.
Referring to Fig. 2, a kind of lock catch type lens base, including base body 3, annular lock 2.
Described base body 3 is in sleeve-shaped, including a cylindrical tube 31 and a pedestal 32, described cylindrical tube
31 inwall is provided with female thread, for being connected with camera lens 1；Described annular lock 2 internal diameter sizes and cylindrical tube 31
Internal diameter size is identical, and described annular lock inwall is provided with the female thread matching with camera lens 1.
In the present embodiment, the installation process of lens base is as follows：First annular is latched and screw in toward the direction of lens barrel front end, such as
Shown in Fig. 3；Then camera lens is screwed in threadably cylindrical tube until imaging surface and the imager chip weight of camera lens
Complete during conjunction to focus, as shown in Figure 4；Again annular is latched the lower surface latching toward the direction turn of base body to annular and bottom
The upper surface of seat body mutually extrudes, as shown in figure 5, due to the effect of frictional force, annular lock will not easily respect thereto this
Body slides thus fixing camera lens.
Lead to camera lens to loosen for making annular loosen during latching in life-time service and run Jiao, also can be in annular lock and mirror
Glue on the junction point of head is so that the relative position that camera lens is latched with annular is fixed further.
Additionally, also can be in the side setting Positioning screw of annular lock, after the completion of lens focusing, toward the direction turn of base
After annular lock fixes camera lens, tighten this Positioning screw so that ring lock button is fixed further.
This utility model lock catch type lens base mainly adopt lock ring fixed position, rather than directly pass through camera lens screw thread and
The threaded adapter fixed position of base, need not accomplish that camera lens is completely the same with whorl of base, base therefore of the present utility model
Go for the camera lens of various different sizes.And due to can allow to have between camera lens screw thread and whorl of base certain between
On the one hand gap, so decrease camera lens (screw thread) and the difficulty of processing of base (screw thread), improve the efficiency of production, on the other hand
Because allowing to loosen between camera lens and base, more convenient when turning, therefore lens focusing is more convenient to operate.
The announcement of book and teaching according to the above description, this utility model those skilled in the art can also be to above-mentioned reality
The mode of applying is changed and is changed.Therefore, this utility model is not limited to specific embodiment disclosed and described above, right
Some modifications and changes of the present utility model should also be as falling in scope of the claims of the present utility model.Additionally, to the greatest extent
Employ some specific terms in pipe this specification, but these terms are merely for convenience of description, not to this utility model
Constitute any restriction.
