Summary of the invention
The present invention proposes a kind of general economical M12 lens base, and cost is low, and energy compatible M12 series camera lens, its structure is optimized for Shooting Technique, not easily produces shrinking deformation, and can ensure with external optical drive mechanism the levelness connecting face when producing.
The present invention by the following technical solutions.
A kind of general economical M12 lens base, described lens base is through injection moulding integrated molding, it comprises lens interface and base, lens interface adopts the barrel of band M12 × 0.5 specification screw thread to coordinate with all M12 specification camera lenses, and the upper and lower symmetria bilateralis of barrel sidewall offers two locking through holes for fixed lens position; It is central and one-body molded with base that barrel is positioned at base upper surface, base central authorities offer the light hole passed through for camera light, described light hole is communicated with barrel, the base left and right sides is arranged with base fixed via, the base lower surface place of base fixed via side is provided with and subtracts glue blind hole, the corner place of base lower surface be provided with connect with external optical drive mechanism by face recess.
Described lens base enters order on light direction at lens interface and is divided into main body withdrawing pattern section and leans on face recess molding section two parts, the described face recess that leans on is positioned at by face recess withdrawing pattern section, when lens base is shaping with Shooting Technique, described main body withdrawing pattern section is through main body withdrawing pattern stripping forming, and the described face recess withdrawing pattern Duan Jing that leans on is by face recess withdrawing pattern stripping forming.
Described lens base is with plastic rubber shaping.
In the present invention, lens base is through injection moulding integrated molding, it comprises lens interface and base, and lens interface adopts the barrel of band M12 × 0.5 specification screw thread to coordinate with all M12 specification camera lenses, and the upper and lower symmetria bilateralis of barrel sidewall offers two locking through holes for fixed lens position; It is central and one-body molded with base that barrel is positioned at base upper surface, base central authorities offer the light hole passed through for camera light, described light hole is communicated with barrel, the base left and right sides is arranged with base fixed via, the corner place of base lower surface be provided with connect with external optical drive mechanism by face recess; Owing to adopting Shooting Technique to produce, therefore its cost is lower, and this structure has good versatility, and be provided with the good compatible M12 camera lens of barrel energy, base position is also provided with and can docks with main flow optical lens driving mechanism by face recess.
In the present invention, the base lower surface place of base fixed via side is provided with and subtracts glue blind hole, and this design effectively can eliminate the shrinking deformation phenomenon produced in Shooting Technique, and the size of finished product base can be conformed to original design, ensures the focusing ability of finished product.
In the present invention, lens base enters order on light direction at lens interface and is divided into main body withdrawing pattern section and leans on face recess molding section two parts, the described face recess that leans on is positioned at by face recess withdrawing pattern section, when lens base is shaping with Shooting Technique, described main body withdrawing pattern section is through main body withdrawing pattern stripping forming, the described face recess withdrawing pattern Duan Jing that leans on is by face recess withdrawing pattern stripping forming, this design makes product can control to lean on the draft depths of face recess withdrawing pattern section when producing in batches, owing to working as draft depths enough hour, by face recess namely without the need to designing draw taper, and be conducive to the driving stability of improving product when docking with optical lens driving mechanism without the driving of gradient by face, therefore this design of this product improves the compatibility of product to optical lens driving mechanism further.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in more detail:
Accompanying drawing 1 is the schematic diagram of product of the present invention;
Accompanying drawing 2 is elevational schematic view of product of the present invention;
Accompanying drawing 3 is partial schematic diagrams of product of the present invention;
In figure: 1-lens interface; 2-barrel; 3-base; 4-locks through hole; Light hole on 5-base; 6-base fixed via; 7-subtracts glue blind hole; 8-is by face recess.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of general economical M12 lens base, described lens base is through injection moulding integrated molding, it comprises lens interface 1 and base 3, lens interface 1 adopts the barrel 2 of band M12 × 0.5 specification screw thread to coordinate with all M12 specification camera lenses, and the upper and lower symmetria bilateralis of barrel 2 sidewall offers two locking through holes 4 for fixed lens position; It is central and one-body molded with base 3 that barrel 2 is positioned at base 3 upper surface, base 3 central authorities offer the light hole 5 passed through for camera light, described light hole 5 is communicated with barrel 2, base 3 left and right sides is arranged with base fixed via 6, the base lower surface place of base fixed via 6 side is provided with and subtracts glue blind hole 7, the corner place of base lower surface be provided with connect with external optical drive mechanism by face recess 8.
