Description

High-accuracy optical lens spacer ring structure

Technical field

The utility model is related to a kind of optical lens assembly, especially a kind of high-accuracy optical lens spacer ring structure.

Background technology

Lens spacing rings are generally used for the installation of camera lens auxiliary lens, such as optical filtering, UV mirrors, the inner ring of installation and camera lens Position, traditional spacer ring are typically directly to be connected using screw-thread fit, since installation site is less, install trouble more.

Invention content

For overcome the deficiencies in the prior art, the utility model provides a kind of high-accuracy optical lens spacer ring easy for installation Structure.

Technical solution adopted by the utility model to solve its technical problems is：

High-accuracy optical lens spacer ring structure, includes the inner ring and spacer ring of cyclic structure, and the outer wall of the inner ring is provided with External screw thread is provided with the internal thread coordinated with external screw thread on the inner wall of the spacer ring, and it is small that the inner ring front end is provided with an outer diameter In the annular guide protrusions of spacer ring internal diameter, the spacer ring is arranged relative at the end face of the side of inner ring and the inner port edge of spacer ring There is an annular guiding surface.

It is a baffle ring on front side of the spacer ring, is provided with the hoodle hole of at least two groups on the inside of the baffle ring, in the hoodle hole Configured with hoodle mechanism, the hoodle mechanism includes the spring and hoodle being arranged in hoodle hole, when inner ring and spacer ring assembling, The hoodle can top pressure on the front end face of inner ring.

The utility model has the beneficial effects that：High-accuracy optical lens spacer ring structure, including the inner ring of cyclic structure and every Circle, the outer wall of the inner ring is provided with external screw thread, the internal thread coordinated with external screw thread is provided on the inner wall of the spacer ring, described Inner ring front end is provided with the annular guide protrusions that an outer diameter is less than spacer ring internal diameter, end face of the spacer ring relative to the side of inner ring Be provided with an annular guiding surface at the inner port edge of spacer ring, the utility model by guide protrusions and annular guiding surface, Internal and external threads can be guided to enter cooperation position so that spacer ring is more readily packed into inner ring, quick and easy for installation.

Description of the drawings

The utility model is further illustrated with reference to the accompanying drawings and examples.

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the schematic cross-section of the utility model；

Fig. 3 is the structural schematic diagram of the utility model spacer ring.

Specific implementation mode

Referring to figs. 1 to Fig. 3, Fig. 1 to Fig. 3 is the structural schematic diagram of one specific embodiment of the utility model, as shown, High-accuracy optical lens spacer ring structure, includes the inner ring 1 and spacer ring 2 of cyclic structure, and the outer wall of the inner ring 1 is provided with outer spiral shell Line is provided with the internal thread coordinated with external screw thread on the inner wall of the spacer ring 2, and 1 front end of the inner ring is provided with an outer diameter and is less than The annular guide protrusions 11 of 2 internal diameter of spacer ring, the spacer ring 2 is relative at the end face of the side of inner ring 1 and the inner port edge of spacer ring 2 It is provided with an annular guiding surface 21, the utility model can guide internal and external threads by guide protrusions and annular guiding surface Into cooperation position so that spacer ring is more readily packed into inner ring, quick and easy for installation.

Preferably, 2 front side of the spacer ring is a baffle ring 22, and 22 inside of the baffle ring is provided with the hoodle hole of at least two groups, It is configured with hoodle mechanism in the hoodle hole, the hoodle mechanism includes the spring 31 being arranged in hoodle hole and hoodle 32, when When inner ring 1 and spacer ring 2 assemble, the hoodle 32 can top pressure on the front end face of inner ring 1 so that have between inner ring 1 and spacer ring 2 There is an outside elastic force so that cooperation more compact between internal and external threads is not susceptible to loosen.

Preferably, be provided with a ceramic layer on the front end face of the inner ring 1, with hoodle 32, avoid hoodle 32 roll when Scratch inner ring 1.

Preferably, it is provided with gasket on the medial surface of the baffle ring 22, to seal the gap between inner ring 1 and spacer ring 2, Prevent dust from entering in camera lens.

The preferred embodiments of the present invention have been specifically described above, certainly, the utility model can also use with The different form of the above embodiment, those skilled in the art under the premise of without prejudice to spirit of that invention made by etc. Same transformation or corresponding change, should all fall within the protection scope of the present invention.
