Description

Technical Field

[0001] The utility model relates to the field of lenses, in particular to a lens assembly structure and a lamp. Background Art

[0002] Conventional lenses are made of glass or plastic, which is hard and can be fixed by clamping. Therefore, conventional lens brackets use a simple snap-on structure, and the bracket buckles the protrusions or steps on the lens to achieve an interference fit to assemble the lens and the bracket together.

[0003] However, the conventional lens and bracket assembly structure (simple snap-fit ​​structure) is difficult to clamp the lens when the lens strength is insufficient, which can easily cause the lens to separate from the bracket. For example, a silicone lens made of soft material is difficult to assemble between the lens and the bracket using the conventional lens and bracket assembly structure. The silicone lens is easily deformed by force and thus falls off the bracket. Utility Model Content

[0039] The utility model is described in detail below in conjunction with the accompanying drawings.

[0040] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0041] In the related art, conventional glass lenses or plastic lenses are hard, and the lenses themselves are not easily deformed. During assembly, a simple buckle structure is used to buckle the protrusions or steps on the lens by the bracket to achieve interference fit to assemble the lens and the bracket together without additional limit. If this assembly method is used on a soft silicone lens, when the silicone lens is deformed by external force, the simple buckle structure loses its buckle point and cannot effectively limit the silicone lens, and the silicone lens is easy to fall off the bracket. For this reason, the technical solution of this application is produced, and the following is combined with Figures 1 to 10 To elaborate.

[0042] Example 1

[0043] like Figures 1 to 5 As shown, a lens assembly structure described in the utility model includes a lens 2 and a bracket bowl 1, wherein the bracket bowl 1 is provided with a plurality of buckle parts 3, and the lens 2 is provided with corresponding buckle grooves 4, and the lens 2 is a soft material lens, for example, the lens 2 is a silicone lens, wherein the soft material lens is a lens with a soft material and insufficient strength compared to a conventional glass or hard plastic material lens.

[0044] like Figure 1 and Figure 2 As shown, in this embodiment, the lens 2 is a cup-shaped lens, and the support bowl 1 is a cup-shaped shell adapted for the cup-shaped lens.

[0045] like Figure 3 As shown, the buckle portion 3 includes a hook 31 and a first groove 32. Figure 4 As shown, the buckle slot 4 includes a convex rib 41 and a second groove 42 .

[0046] The hook 31 can be snapped into the second groove 42, and the rib 41 can be snapped into the first groove 32 to achieve the assembly of the lens 2 and the bracket bowl 1. Figure 5 shown.

[0047] like Figure 1 and Figure 2 As shown, the buckle parts 3 are evenly arranged along the circumference of the support bowl 1, and the buckle grooves 4 are evenly arranged along the circumference of the lens 2.
