Furthermore, the threaded connection is prone to loosening during long-term use, which further affects the sealing performance. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a waterproof sealing structure for embedded LED lamps. This solves the problem that the waterproof sealing structure of existing LED lamps mostly adopts a single sealing gasket or a simple threaded connection, which has the problem of insufficient sealing reliability. Moreover, the threaded connection is prone to loosening during long-term use, which further affects the sealing performance.
[0005] In view of this, the present invention provides a waterproof sealing structure for an embedded LED lamp, including a lamp body and a sealing cover installed at the bottom of the lamp body, wherein a sealing mechanism is provided between the sealing cover and the lamp body;
[0006] The sealing mechanism includes a rotating shaft, a retaining plate, and a sealing gasket. The bottom of the lamp body has an installation groove, and the sealing cover is installed in the installation groove. A groove is formed on one side of the inner wall of the installation groove. The rotating shaft is rotatably connected in the groove. A torsion spring is installed at the connection between the rotating shaft and the inner wall of the groove. The retaining plate is fixedly installed on the side wall of the rotating shaft. The surface of the sealing cover has a groove that matches the retaining plate. The groove is an arc-shaped groove, and the depth of the groove gradually decreases from one end to the other. The sealing gasket is fixedly installed on the inner wall of the sealing cover.
[0007] Optionally, a spring is fixedly installed on the top of the inner wall of the mounting groove, and a pressure plate is fixedly installed on the spring.
[0008] Optionally, a threaded groove is provided on one side of the inner wall of the mounting groove, and a thread that matches the threaded groove is provided on the side wall of the sealing cover.
[0009] Optionally, the center of the sealing cover is made of transparent material, and the cross-section of the edge of the sealing cover is U-shaped.
[0010] Optionally, a protrusion is fixedly installed on the side wall of the sealing cover near the bottom, and a plurality of protrusions are provided.
[0011] Optionally, the sealing cover has an installation cavity that communicates with the interior of the lamp body. A waterproof and breathable membrane is fixedly installed at one end of the installation cavity where it communicates with the interior of the lamp body. A screen is fixedly installed on the inner wall of the installation cavity. The screen is located at the bottom of the waterproof and breathable membrane, and the bottom of the screen is filled with a filler.
[0012] Optionally, the bottom of the mounting cavity is provided with a drain hole that communicates with the outside, and the drain hole is located at the bottom of the screen.
[0013] As can be seen from the above technical solutions, the embodiments of this utility model have the following advantages:
[0014] 1. This utility model discloses a waterproof sealing structure for an embedded LED lamp. The sealing mechanism involves aligning the sealing cover with the mounting groove and inserting it. Rotating the sealing cover secures it to the mounting groove via a threaded connection. During this process, a retaining plate contacts the groove under the force of a torsion spring. As the sealing cover is gradually tightened, it engages with the groove, fixing the cover in place. The retaining plate exerts continuous pressure on the sealing cover, ensuring a tight fit between the sealing gasket on the inner wall of the sealing cover and the bottom of the lamp body, preventing the sealing cover from loosening. This achieves double fixing, effectively blocking external moisture and dust from entering.
[0015] 2. This utility model discloses a waterproof sealing structure for an embedded LED lamp, employing a waterproof and breathable membrane design. This design allows for gas exchange between the lamp body and the mounting cavity, balancing internal air pressure and preventing the absorption of moisture due to negative pressure caused by temperature changes. It also prevents external liquid water from entering the lamp body. A screen is used to hold the filler, which can be a moisture-absorbing material such as silica gel desiccant. This filler can absorb trace amounts of moisture entering the mounting cavity through the waterproof and breathable membrane, preventing condensation inside the lamp. When the filler reaches saturation, the moisture can be naturally discharged through the drain hole, allowing for moisture removal without disassembling the sealing cover, further enhancing the lamp's waterproof durability.
[0016] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0023] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.
[0024] The following describes in detail, with reference to the accompanying drawings, a waterproof sealing structure for an embedded LED lamp according to an embodiment of the present invention.
[0025] Example 1
[0026] For easier understanding, please refer to Figures 1 to 4 An embodiment of the waterproof sealing structure of an embedded LED lamp provided by this utility model includes a lamp body 1 and a sealing cover 2 installed at the bottom of the lamp body 1. A sealing mechanism is provided between the sealing cover 2 and the lamp body 1.
[0027] The sealing mechanism includes a rotating shaft 12, a clamping plate 13, and a sealing gasket 15. The bottom of the lamp body 1 has an installation groove 9, and the sealing cover 2 is installed in the installation groove 9. A groove 10 is provided on one side of the inner wall of the installation groove 9. The rotating shaft 12 is rotatably connected in the groove 10. A torsion spring is installed at the connection between the rotating shaft 12 and the inner wall of the groove 10. The clamping plate 13 is fixedly installed on the side wall of the rotating shaft 12. The surface of the sealing cover 2 has a groove 14 that fits the clamping plate 13. The groove 14 is an arc-shaped groove, and the depth of the groove 14 gradually decreases from one end to the other. The sealing gasket 15 is fixedly installed on the inner wall of the sealing cover 2.
[0028] It should be noted that when installing the sealing cover 2, the sealing cover 2 is aligned with the mounting groove 9 and inserted. The sealing cover 2 is threaded into the mounting groove 9 by rotating it. During this process, the retaining plate 13 will contact the retaining groove 14 under the force of the torsion spring. As the sealing cover 2 is gradually tightened, it will be inserted into the retaining groove 14 to fix the sealing cover 2. The retaining plate 13 will generate a continuous pressing force on the sealing cover 2, causing the sealing gasket 15 on the inner wall of the sealing cover 2 to fit tightly against the bottom of the lamp body 1, preventing the sealing cover 2 from loosening, thereby achieving double fixation and effectively blocking external moisture and dust from entering. When disassembling, the retaining plate 13 is pushed out of the retaining groove 14 by the stepped depth structure inside the retaining groove 14 by forcefully rotating the sealing cover 2, thereby unlocking.
[0029] In some embodiments, such as Figure 3 As shown, a spring is fixedly installed on the top of the inner wall of the mounting groove 9, and a pressure plate 11 is fixedly installed on the spring. A threaded groove is opened on one side of the inner wall of the mounting groove 9, and a thread that matches the threaded groove is opened on the side wall of the sealing cover 2.
[0030] It should be noted that the setting of the spring and pressure plate 11 allows the pressure plate 11 to press tightly against the top of the sealing cover 2 under the action of the spring after the sealing cover 2 is inserted into the mounting groove 9, further enhancing the clamping force between the sealing cover 2 and the lamp body 1, and achieving double sealing in conjunction with the sealing mechanism; the sealing cover 2 is threadedly connected in the mounting groove 9 through the threaded groove and threads.
[0031] In some embodiments, such as Figure 3 As shown, the center of the sealing cover 2 is made of transparent material, the cross-section of the edge of the sealing cover 2 is U-shaped, and a protrusion 16 is fixedly installed on the side wall of the sealing cover 2 near the bottom. Several protrusions 16 are provided.
[0032] It should be noted that the center of the sealing cover 2 is made of transparent materials such as high-transmittance tempered glass or PC material, which can ensure that the light from the LED lamps can pass through normally without affecting the lighting effect; the U-shaped cross-section design at the edge can increase the contact area between the sealing cover 2 and the mounting groove 9, improve the fit of the sealing gasket 15, and enhance the structural strength of the edge of the sealing cover 2; the protrusions 16 are evenly distributed on the bottom of the side wall of the sealing cover 2, which makes it easy for operators to use tools to clamp or manually grasp, thereby easily rotating the sealing cover 2 to complete the installation and disassembly, improving the convenience of maintenance.
[0033] Example 2
[0034] In some embodiments, such as Figure 3As shown, the sealing cover 2 has an installation cavity 3 that communicates with the interior of the lamp body 1. A waterproof and breathable membrane 8 is fixedly installed at one end of the installation cavity 3 where it communicates with the interior of the lamp body 1. A screen 5 is fixedly installed on the inner wall of the installation cavity 3. The screen 5 is located at the bottom of the waterproof and breathable membrane 8. The bottom of the screen 5 is filled with filler 6. A drain hole 4 that communicates with the outside is opened at the bottom of the installation cavity 3. The drain hole 4 is located at the bottom of the screen 5.
[0035] It should be noted that the waterproof and breathable membrane 8 is made of breathable but waterproof materials such as polytetrafluoroethylene, which enables gas exchange between the interior of the lamp body 1 and the mounting cavity 3, balances the internal air pressure, and prevents the absorption of water vapor due to negative pressure caused by temperature changes. At the same time, it blocks external liquid water from entering the interior of the lamp body 1. The screen 5 is used to hold the filler 6, which can be made of moisture-absorbing materials such as silica gel desiccant. It can absorb the trace amount of moisture that enters the mounting cavity 3 through the waterproof and breathable membrane 8, preventing moisture from condensing inside the lamp. When the filler 6 is saturated with water, it can be naturally discharged through the drain hole 4. Water can be cleaned without disassembling the sealing cover 2, further improving the waterproof durability of the lamp.
[0036] Working principle: During installation, first fix the sealing gasket 15 to the inner wall of the sealing cover 2, then align the sealing cover 2 with the mounting groove 9 of the lamp body 1, rotate the sealing cover 2 through the protrusion 16, and initially fix it with the threaded engagement. During this process, the clamping plate 13 will contact the clamping groove 14 under the action of the torsion spring. As the sealing cover 2 is gradually tightened, it will be inserted into the clamping groove 14 to fix the sealing cover 2. The clamping plate 13 will generate a continuous pressing force on the sealing cover 2, causing the sealing gasket 15 on the inner wall of the sealing cover 2 to fit tightly with the bottom of the lamp body 1, preventing the sealing cover 2 from loosening, thereby achieving double fixation and effectively blocking external moisture and dust from entering.
[0037] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
