Moisture intrusion can easily lead to lens fogging and damage to optical components, affecting image quality and equipment lifespan. Traditional security lenses have a simple waterproof structure, relying mostly on simple sealing rings or adhesive, which is insufficient to meet the multiple waterproof requirements of long-term complex environments. Furthermore, the compatibility of various components and the rationality of the structure are insufficient, failing to effectively ensure stable operation of the lens under harsh conditions. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a multi-layer waterproof security lens that improves the overall waterproof performance and reliability.

[0005] The present invention adopts the following technical solution:

[0006] A multi-layer waterproof security lens includes a lens body, which comprises a lens barrel, a sealing element, a clamping ring, a front lens, an internal lens, and a filter. The top of the lens barrel has an annular groove. The sealing element is housed within the annular groove. The clamping ring is fitted onto the upper outer periphery of the lens barrel, and a first adhesive sealing layer is formed at the connection between the clamping ring and the bottom of the lens barrel. The front lens covers the top of the lens barrel and engages with the clamping ring. The internal lens is fixed inside the lens barrel, and a second adhesive sealing layer is formed at the connection between the internal lens and the bottom of the lens barrel. The filter is located at the bottom of the lens barrel, and a third adhesive sealing layer is formed at the connection between the filter and the lens barrel.

[0007] A further improvement to the above technical solution is that a dispensing groove is provided at the bottom of the lens barrel, and the dispensing groove is used to accommodate the third dispensing sealing layer.

[0008] A further improvement to the above technical solution is that a through-hole is provided inside the lens barrel, and the cavity is used to accommodate the internal lens.

[0009] A further improvement to the above technical solution is that the outside of the lens barrel is provided with a connecting part, and the surface of the connecting part is provided with connecting threads.

[0010] A further improvement to the above technical solution is that the lens barrel and the clamping ring are both injection-molded parts or metal parts.

[0011] A further improvement to the above technical solution is that the sealing element is an annular sealing ring, which includes an annular portion, an upper protrusion portion and a lower protrusion portion; the annular portion is integrally formed with the upper protrusion portion and the lower protrusion portion respectively; there are two upper protrusion portions and two lower protrusion portions, with the two upper protrusion portions arranged parallel to each other on the first side of the annular portion, and the two lower protrusion portions arranged parallel to each other on the second side of the annular portion.

[0012] A further improvement to the above technical solution is that the clamping ring includes an inner ring and an outer ring arranged coaxially; the top of the inner ring is provided with a receiving hole for adapting to the front lens, and the inner side of the receiving hole is provided with a fitting slope, which is adapted to the edge structure of the front lens; the bottom of the outer ring is provided with an outwardly extending annular flange edge.

[0013] A further improvement to the above technical solution is that the front-end lens is either a glass lens or a PC lens.

[0014] A further improvement to the above technical solution is that the front-end lens is one of a biconvex lens, a biconcave lens, or a crescent-shaped lens.

[0015] A further improvement to the above technical solution is that the number of internal lenses is set to several groups, and several internal lenses are stacked sequentially inside the receiving cavity; all internal lenses are either glass lenses or PC lenses.

[0016] The beneficial effects of this utility model are as follows:

[0017] This utility model's lens barrel, through the inclusion of an annular groove, a receiving cavity, an adhesive groove, and a connecting part, provides precise installation space for seals, internal lenses, and other components. The connecting threads of the connecting part facilitate assembly of the lens with external equipment. Injection molding or metal materials ensure structural strength and adaptability. Its multi-structure design allows for the orderly cooperation of various components, forming the basic carrier for achieving waterproof and optical functions. The seal uses an annular sealing ring with a multi-protrusion structure. These protrusions fit tightly with the annular groove and the front lens, significantly increasing the waterproof contact area, improving sealing reliability, and effectively preventing external moisture from intruding from the top. The coaxial inner and outer ring structure of the clamping ring has an inner ring that precisely fits the beveled surface of the front lens, ensuring stable lens installation and auxiliary sealing.

[0028] like Figures 1 to 5The image shows an embodiment of the present invention, relating to a multi-layer waterproof security lens, including a lens body 10. The lens body 10 includes a lens barrel 20, a sealing element 30, a clamping ring 40, a front lens 11, an internal lens 12, and a filter 13. The top end of the lens barrel 20 has an annular groove 21. The sealing element 30 is housed inside the annular groove 21. The clamping ring 40 is fitted onto the upper outer periphery of the lens barrel 20, and a first adhesive sealing layer 14 is formed at the connection between the clamping ring 40 and the bottom of the lens barrel 20. The front lens 11 covers the top end of the lens barrel 20 and engages with the clamping ring 40. The internal lens 12 is fixed inside the lens barrel 20, and a second adhesive sealing layer 15 is formed at the connection between the internal lens 12 and the bottom of the lens barrel 20. The filter 13 is disposed at the bottom end of the lens barrel 20, and a third adhesive sealing layer 16 is formed at the connection between the filter 13 and the lens barrel 20.

[0029] Specifically, this embodiment integrates a lens barrel 20, a sealing element 30, a clamping ring 40, a front lens 11, an internal lens 12, and a filter 13 to form a complete lens body 10. Through the coordinated use of multiple structures such as the annular groove 21 and adhesive sealing layers, multiple layers of waterproofing are formed from the top, inside, and bottom, ensuring the overall waterproofing of the lens and the stability of the optical components. This solves the problem of single-layer waterproofing in traditional lenses and improves adaptability to complex environments and imaging reliability. In this embodiment, the first adhesive sealing layer 14, the second adhesive sealing layer 15, and the third adhesive sealing layer 16 are all sealing adhesive layers.

[0030] like Figure 4 As shown, a dispensing groove 22 is formed at the bottom of the lens barrel 20, which is used to accommodate the third dispensing sealing layer 16. Specifically, in this embodiment, the dispensing groove 22 precisely accommodates the third dispensing sealing layer 16, specifically strengthening the bottom waterproofing, and working with the filter 13 to seal the bottom gaps, preventing water from entering from the bottom, making up for the shortcomings of bottom waterproofing, improving the multi-layer waterproofing system, and enhancing the overall sealing performance of the lens.

[0031] like Figure 2 As shown, the lens barrel 20 has a through-cavity 23 inside, which is used to accommodate the internal lens 12. Specifically, the through-cavity 23 provides a suitable installation space for the internal lens 12, ensuring stable assembly of the internal lens 12, facilitating the stacking of multiple lens groups, optimizing the internal optical path design, assisting in waterproofing with the adhesive layer, and providing a structural basis for optical correction, thereby improving image quality and the rationality of the internal structure.

[0032] like Figure 2As shown, the lens barrel 20 has a connecting part 24 on its exterior, and the surface of the connecting part 24 is provided with connecting threads (not shown in the figure). Specifically, the connecting part 24 and connecting threads (not shown in the figure) facilitate the assembly of the lens with external devices such as gimbals and protective covers. The connecting threads (not shown in the figure) enhance the connection stability and sealing, adapt to the installation requirements of different security scenarios, and expand the application range of the lens. At the same time, the structure of the connecting part 24 strengthens the overall strength of the lens barrel 20 and indirectly assists in waterproofing.

[0033] like Figure 1 As shown, the lens barrel 20 and the clamping ring 40 are both injection-molded parts or metal parts. Specifically, the use of injection-molded parts or metal parts adapts to different production needs and environments. Injection-molded parts are lightweight and easy to mold, while metal parts have high strength and good weather resistance, flexibly meeting cost and performance requirements, ensuring the structural strength and waterproof stability of the lens, and improving product versatility and production adaptability.

[0034] like Figure 4 and Figure 5 As shown, the sealing element 30 is an annular sealing ring, which includes an annular portion 31, an upper protrusion 32, and a lower protrusion 33. The annular portion 31 is integrally formed with the upper protrusion 32 and the lower protrusion 33. There are two upper protrusions 32 and two lower protrusions 33, with the two upper protrusions 32 arranged parallel to each other on the first side of the annular portion 31, and the two lower protrusions 33 arranged parallel to each other on the second side of the annular portion 31. Specifically, the annular portion 31, the upper protrusion 32, and the lower protrusion 33 constitute a special annular structure of the sealing element 30. The multi-protrusion structure effectively enhances the fit and sealing with the annular groove 21 and the front lens 11. The integral forming ensures the structural strength and waterproof consistency. Waterproofing is strengthened from the key gap at the top, resisting water infiltration and improving the reliability and durability of the top waterproofing.

[0035] like Figure 2 As shown, the clamping ring 40 includes an inner ring 41 and an outer ring 42 coaxially arranged. The top of the inner ring 41 is provided with a receiving hole 43 for fitting the front lens 11, and the inner side of the receiving hole 43 is provided with a fitting slope 44, which fits the edge structure of the front lens 11. The bottom of the outer ring 42 is provided with an outwardly extending annular flange edge 45. Specifically, the fitting slope 44 of the inner ring 41 of the clamping ring 40 fits the edge of the front lens 11, ensuring the installation accuracy and sealing of the front lens 11. The annular flange edge 45 of the outer ring 42 strengthens the structural connection with the lens barrel 20 and the front lens 11, improves the stability of the top assembly and the waterproof synergy, optimizes the function of the clamping ring 40, and makes the top waterproofing and optical assembly more reliable.

[0036] like Figure 1As shown, the front-end lens 11 is either a glass lens or a PC lens. Specifically, the front-end lens 11 can be either a glass lens or a PC lens. Glass lenses have superior optical performance and strong weather resistance, while PC lenses are lightweight and low-cost, adapting to different cost and performance requirements. This ensures front-end imaging while flexibly balancing lens design with application scenarios, thus improving product adaptability.

[0037] like Figure 1 As shown, the front-end lens 11 is one of a biconvex lens, a biconcave lens, or a crescent-shaped lens. Specifically, the front-end lens 11 adopts multiple lens types such as biconvex, biconcave, and crescent-shaped to adapt to different optical path correction needs. Biconvex lenses focus light, biconcave lenses astigmatize light, and crescent-shaped lenses optimize aberrations. Together with the internal lens 12, they optimize the overall optical path, improve imaging clarity and image quality, and meet the diverse monitoring scenario needs such as strong light, weak light, and distortion correction.

[0038] like Figure 2 As shown, the number of internal lenses 12 is set to several groups, and several internal lenses 12 are stacked sequentially inside the receiving cavity 23; the internal lenses 12 are all one of glass lenses or PC lenses. Specifically, the stacking of multiple groups of internal lenses 12 and the choice of glass or PC material are optional. Multiple stacking optimizes the optical path, and the material is adapted to different costs and optical requirements. An adjustable optical structure is built inside the lens to improve image quality and functional expandability. At the same time, the adhesive layer is used to enhance internal waterproofing and structural stability.

[0039] The working principle of this utility model is as follows:

[0040] Waterproofing and imaging functions are achieved through the coordinated use of multiple components: The lens barrel 20 serves as the basic load-bearing structure, with an annular groove 21 to accommodate the sealing element 30, providing the first waterproof barrier for the top of the lens; the clamping ring 40 is fitted onto the upper part of the lens barrel 20, and its first adhesive sealing layer 14 at the bottom of the lens barrel 20 strengthens the waterproofing at the connection between the top and the lens barrel 20, while the inner ring 41 fits against the inclined surface 44 to adapt to the front lens 11, ensuring the installation stability and waterproofing of the front lens 11; the front lens 11 covers the top of the lens barrel 20 and engages with the clamping ring 40. It participates in top waterproofing and serves as the first component for optical imaging; the internal lens 12 is fixed in the receiving cavity 23 of the lens barrel 20 and cooperates with the second adhesive sealing layer 15 at the bottom to form a dual structure of waterproofing and optical correction inside the lens, and multiple stacks can optimize the optical path; the filter 13 is connected to the bottom end of the lens barrel 20 through the third adhesive sealing layer 16 to seal the bottom gap. Each component constructs a multi-layer waterproof defense line from the top, joint, inside and bottom, and at the same time, it uses the optical characteristics of different lenses to cooperate in imaging to achieve stable monitoring in complex environments.

[0041] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
