DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. EMBODIMENT

[0025] Please refer to Figures 1 to 5 , the embodiment provides a technical scheme: the anti-dropping silk screen lens ring, including

[0028] The edge of the silk screen lens ring body 1 is provided with a blocking structure.

[0029] In the embodiment, preferably, the glue layer 12 and the glue layer 14 are respectively at the bottom and the bottom of the acrylic plate layer 13, and the PET bottom plate 11 is arranged at the bottom of the glue layer 12.

[0030] In this embodiment, preferably, the tempered glass layer 15 is arranged on top of the upper glue layer 14, and the top of the tempered glass layer 15 is provided with an AF oil coating layer 16.

[0031] In this embodiment, preferably, the reinforcing structure 17 includes a central glue groove 171 formed inside the edge of the acrylic plate layer 13, and the two ends of the central glue groove 171 are provided with glue inlet holes 172, and the upper and lower surfaces of the acrylic plate layer 13 are provided with tapered entrances 173 communicating with the glue inlet holes 172. The design of the reinforcing structure 17 allows the glue to enter the central glue groove 171 through the tapered entrances 173 and the glue inlet holes 172 during the glue coating process. After the upper glue layer 14 and the lower glue layer 12 are cured, the glue previously entered into the central glue groove 171, the glue inlet holes 172 and the tapered entrances 173 is also cured. At this time, the cured glue in the central glue groove 171, the glue inlet holes 172 and the tapered entrances 173 forms an anchor-like structure, which allows the upper glue layer 14 and the lower glue layer 12 to be stably glued to the surface of the acrylic plate layer 13, thereby preventing the acrylic plate layer 13 from falling off due to glue opening.

[0032] In this embodiment, preferably, the blocking structure includes a limiting baffle 31 arranged on the side of the silk screen lens ring body 1 and a fitting pad 32 mounted on the edge of the top surface of the silk screen lens ring body 1. The limiting baffle 31 and the fitting pad 32 are in an integrated structure, and the bottom end of the limiting baffle 31 is attached to the side of the optical equipment lens base plate 5. The limiting baffle 31 can effectively limit and prevent the silk screen lens ring body 1 from moving or deflecting when subjected to lateral force or vibration during use or fitting, thereby further preventing the silk screen lens ring body 1 from falling off.

[0033] In this embodiment, preferably, the bottom end of the limiting baffle 31 is provided with a plurality of anti-skid grooves 311, which can prevent the limiting baffle 31 from slipping after being attached to the optical equipment lens base plate 5.

[0034] In this embodiment, preferably, the bottom surface of the fitting pad 32 is provided with an integrated T-shaped clamp head 321, both of which are made of rubber material and can elastically deform when subjected to pressure. The top edge of the silk screen lens ring body 1 is provided with a T-shaped clamping groove 33 for the T-shaped clamp head 321 to be clamped into, so that the fitting pad 32 can be stably clamped on the top of the silk screen lens ring body 1 through the T-shaped clamp head 321, ensuring the installation stability of the fitting pad 32 and the limiting baffle 31. When the fitting pad 32 and the limiting baffle 31 need to be removed later, the fitting pad 32 can be easily lifted to make the T-shaped clamp head 321 elastically deform and be pulled out of the T-shaped clamping groove 33, so that the fitting pad 32 and the limiting baffle 31 can be easily removed, facilitating the subsequent disassembly, maintenance or replacement of the blocking structure.

[0035] In this embodiment, preferably, the thickness of the PET base plate 11 is 0.18mm, the thickness of the glue layer 12 is 0.23um, the thickness of the acrylic plate layer 13 is 1.35mm, the thickness of the glue layer 14 is 0.18mm, the thickness of the tempered glass layer 15 is 0.33um, the tempered glass layer 15 is high-aluminum glass, the light transmittance of the tempered glass layer 15 is ≥95% (test standard ASTM D1003), the surface hardness of the tempered glass layer 15 is 9H (test standard JIS K5600-5-4), the edge strength of the tempered glass layer 15 is >20KG (test standard ISO 1288-1), the contact angle of the AF oil coating layer 16 is 0.8-0.9KA, KA is the abbreviation of "Kilo-Angle", which means that the coating can make the water droplets form a contact angle of 80°-90° on the surface, the larger the contact angle, the stronger the hydrophobicity, and the better the anti-fingerprint effect.
