[0002] With the increasing use of underwater auxiliary lighting, underwater viewing lighting, aquaculture lighting and other application scenarios, the demand for underwater lights is increasing day by day. Underwater lights are exposed to the harsh and complex underwater environment, water flow and pressure, underwater impurities and other factors for a long time. To ensure the normal operation of the internal light source and power supply circuit, they must be reliably sealed.

[0003] Traditional underwater lights usually achieve a sealing effect by tightening the end cap and bolts at the end of the cylinder to compress the sealing surface, or by using the pressure of the medium inside the cylinder to generate a compressive force on the sealing surface. These existing sealing methods have problems such as incomplete sealing, poor durability, and inconvenient assembly, which makes the lamps easily damaged by water, affecting the performance and lifespan, increasing maintenance costs and safety hazards. Therefore, there is an urgent need to innovate and optimize the sealing structure.

[0004] In view of the above-mentioned existing technologies, it is necessary to improve the sealing structure of the existing underwater lights by automation. To this end, the applicant has made a useful design, and the technical solution to be introduced below was produced in this context. Utility Model Content

[0018] The specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the description of the embodiments does not limit the technical solution. Any changes in form rather than substance based on the concept of the present invention should be regarded as within the scope of protection of the present invention.

[0019] In the following description, all concepts related to directionality (or orientation) such as up, down, left, right, front and back are with respect to the position state of the figure being described, and are intended to facilitate public understanding. Therefore, they should not be understood as special limitations on the technical solutions provided by the present invention.

[0020] See also Figure 1 and Figure 3 The utility model relates to a sealing structure of an underwater lamp, including a lamp tube 1, a front sealing ring 2, a plane lens 3, a sealing gasket 4, a front cover 5, a rear sealing ring 6, a rear cover plate 7 and a cable connector 8. The lamp tube 1, the front cover 5 and the rear cover plate 7 are made of aluminum alloy, which makes the underwater lamp as a whole light and has obvious heat dissipation effect. The surface of the aluminum alloy is also hard-oxidized, thereby improving the overall hardness and corrosion resistance of the lamp body.

[0021] See Figure 1 and Figure 3The plane lens 3 is arranged at the front end of the lamp tube 1. It adopts a high-transmittance plane lens, which can effectively transmit the propagation of light. It adopts a certain thickness so that it will not be crushed by high water pressure in deep water. The lamp tube 1 is formed with a lens installation cavity 13 at the front end opening for accommodating the plane lens 3. The rear end of the lens installation cavity 13 is formed with a circle of steps 14 to limit the plane lens 3. The step 14 is provided with a front sealing ring groove 141, and the front sealing ring 2 is embedded in the front sealing ring groove 141 and fixed by the front sealing ring groove 141 and the plane lens 3. When the plane lens 3 is squeezed downward, it can play an effective sealing role.

[0022] Furthermore, the lamp tube 1 is provided with a middle groove 15 in the middle of the outer wall, which can be used to fix the underwater light with a clamp-like accessory. The lamp tube 1 is provided with rear grooves 16 at intervals along the circumferential direction on the outer wall of the rear end, which facilitates the tightening and fixing of the lamp tube 1.

[0023] The front cover 5 is provided with a light-transmitting hole 51 in the middle to facilitate the passage of light. The outer wall of the front opening of the lamp tube 1 is formed with an outer thread 12, and the inner wall of the front cover 5 is formed with an inner thread 52. The front cover 5 is tightly connected to the front opening of the lamp tube 1 through threaded fit. The sealing gasket 4 is annular, arranged in the front cover 5 and pressed against the front side of the plane lens 3. The outer diameter of the sealing gasket 4 is the same as the inner diameter of the lens mounting cavity 13 of the lamp tube 1, and the inner diameter of the sealing gasket 4 is the same as the inner diameter of the front cover 5.

[0024] Furthermore, the front cover 5 is provided with positioning holes 53 on the outer end surface and at intervals around the light-transmitting hole 51, and the front cover 5 is provided with positioning grooves 54 at intervals around the circumferential direction on the side wall. The positioning holes 53 and positioning grooves 54 are used to cooperate with external tightening tools to facilitate the tightening and fixing of the front cover 5 and the lamp tube 1.

[0025] The rear cover plate 7 is pressed onto the rear end face of the lamp tube 1 through the connecting piece 9. In this embodiment, the connecting piece 9 is a hexagonal stainless steel screw with good corrosion resistance. Screw holes are correspondingly provided on the rear cover plate 7 and the lamp tube 1, which are tightened by screws for easy installation. The rear cover plate 7 is narrowed on the side facing the lamp tube 1 to form a boss 71. The boss 71 extends into the rear end opening of the lamp tube 1. The rear end opening of the lamp tube 1 is formed as an oblique opening 11 to facilitate the installation of the boss 71. The boss 71 is formed with a rear sealing ring groove 711 on the outer wall. The rear sealing ring 6 is embedded in the rear sealing ring groove 711 and protrudes from the rear sealing ring groove 711. When the rear cover plate 7 is tightened, the rear sealing ring 6 is tightly matched with the oblique opening 11 of the lamp tube 1, which can effectively prevent water. The rear cover 7 has a central connector hole 72 extending through the boss 71. The outlet end 81 of the cable connector 8 connects to the hole 72 via a threaded connection, allowing the cable to be introduced into the lamp tube 1 for easy installation. A connector seal 82 is also provided at the rear end of the outlet end 81, corresponding to the threaded connection. This seal also effectively prevents water from entering the wires and the interior of the lamp, ensuring safety.

[0026] The utility model adopts a multi-stage sealing design to construct a strict waterproof system, which can effectively cope with high water pressure and complex water flow, and has reliable waterproof durability, thereby achieving the purpose of the invention.
