According to the utility model, the clamping groove is arranged in the lens barrel, and the glass lens can be directly supported on the groove wall of the clamping groove, so that the glass lens is separated from the plastic lens, the stability can be improved, and the glass lens and the plastic lens are not mutually influenced when inclining, so that the inclination accumulation is avoided, and the accumulation tolerance is avoided; the Tilt phenomenon can be effectively prevented and relieved.

Description

Technical Field

[0001] The utility model relates to the technical field of lenses, in particular to a lens barrel seat structure. Background Art

[0002] The lens barrel is a special metal or plastic cylinder used to fix the lens. The existing lens barrel structure is as follows Figure 1 As shown, the glass lens and the plastic lens are fixed in the lens barrel, but most of the existing glass lenses are stacked on one side of the plastic lens, and the glass lens directly rests on the plastic lens. Once the glass lens tilts, the glass lens will squeeze the plastic lens, causing the plastic lens to tilt together, resulting in a large cumulative tolerance, thereby causing a Tilt phenomenon. For lenses that are more sensitive to tilt, it will directly cause damage to the lens.

[0003] Therefore, the utility model provides a lens barrel seat structure. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a lens barrel seat structure to solve the problems raised in the above-mentioned background technology. The present invention can improve stability, and there will be no tilt accumulation, no cumulative tolerance, and can effectively prevent and reduce the Tilt phenomenon.

[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions: the lens barrel seat structure includes a lens barrel, a glass lens and a plastic lens are installed in the lens barrel, and a card slot is opened in the lens barrel, and the card slot corresponds to the glass lens.

[0006] Furthermore, the slot forms a step structure on the inner side of the lens barrel, and one side of the glass lens contacts the slot wall of the slot.

[0007] Furthermore, the glass lens and the plastic lens are both fixed in the lens barrel.

[0008] Furthermore, the side of the glass lens close to the slot wall is a planar structure, and the side of the glass lens away from the slot wall is a curved structure.

[0009] Beneficial effects of the utility model: the lens barrel seat structure of the utility model comprises a lens barrel, a glass lens, a plastic lens and a card slot.

[0010] A card slot is opened in the lens barrel, and the glass lens can be directly supported on the slot wall, so that the glass lens is separated from the plastic lens. This not only improves stability, but also the tilt of the glass lens and the plastic lens will not affect each other, so there will be no tilt accumulation, no cumulative tolerance, and can effectively prevent and reduce the Tilt phenomenon.

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0015] See also Figure 1 and Figure 2 The utility model provides a technical solution: a lens barrel seat structure, comprising a lens barrel 1, wherein a glass lens 2 and a plastic lens 3 are mounted in the lens barrel 1, and a card slot 4 is opened in the lens barrel 1, and the card slot 4 corresponds to the glass lens 2.

[0016] In this embodiment, the card slot 4 forms a step structure on the inner side of the lens barrel 1, one side of the glass lens 2 contacts the groove wall of the card slot 4, the glass lens 2 and the plastic lens 3 are both fixed in the lens barrel 1, the side of the glass lens 2 close to the groove wall of the card slot 4 is a flat structure, and the side of the glass lens 2 away from the groove wall of the card slot 4 is a curved structure.

[0017] Specifically, the glass lens 2 is directly supported on the groove wall of the card groove 4, that is, the glass lens 2 is directly supported on the lens barrel 1. At this time, the lens barrel 1 supports the glass lens 2 with high stability, and the glass lens 2 does not contact the plastic lens 3. The plastic lens 3 is fixed in the lens barrel 1 by glue dispensing, and there will be no cumulative tolerance, which can prevent and reduce tilting.

[0018] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
