[0017] Beneficial effects

[0018] This utility model provides a waterproof ceiling light. Compared with the prior art, it has the following advantages:

[0019] 1. This waterproof ceiling light rotates by turning the anti-slip ring, which in turn drives the screw to rotate. Since the lifting block is restricted by the outer wall of the shell, the lifting block will move upward along the screw after the screw rotates. The lifting block will move along with the rubber top frame until the rubber top frame presses against the ceiling, thereby sealing the gap between the shell and the ceiling and effectively preventing moisture and dust from entering.

[0020] 2. This waterproof ceiling light uses an assembly plate fixed to the ceiling to determine the overall position of the device. When it is necessary to replace the lamp body on the sealing component mounting plate, the pull rod can be pulled to move the slider. The slider will then move the pin to disengage from the inside of the limit rod, thus removing the restriction on the limit rod and disassembling the entire sealing component for easy replacement of the lamp body. After the lamp body is replaced, the limit rod can be reinserted into the top block, and the spring force will press the pin tightly into the inside of the limit rod to re-fix it.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0034] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] Reference Figures 1 to 10 This application provides a waterproof ceiling light, including a housing 1. A sealing component 2 is provided on the outer wall of the housing 1. A convenient replacement component 3 is provided on the top of the sealing component 2. The sealing component 2 includes a protrusion 21, which is fixedly connected to the outer wall of the housing 1. A screw 22 is rotatably connected to the top of the protrusion 21. A lifting block 24 is threadedly connected to the outer wall of the screw 22. A rubber top frame 25 is fixedly connected to the top of the lifting block 24, which is used for sliding connection to the outer wall of the housing 1. An anti-slip rotating ring 23 is fixedly connected to one end of the screw 22. An insert 27 is fixedly connected to one end of the lifting block 24, and an inner groove 26 is formed inside one end of the other lifting block 24, allowing the insert 27 to be inserted into the inner groove 26. A cross bracket 28 is fixedly connected between the inner walls of the housing 1, and a mounting plate 213 is fixedly connected to the bottom of the cross bracket 28. The housing 1 has an airtight groove 212 inside. The sealing assembly 2 also includes a lampshade 29. The lampshade 29 is movably connected to a bolt 210, which is threaded inside the housing 1. The top of the lampshade 29 is fixedly connected to a frame 211, which can be inserted into the airtight groove 212.

[0036] In specific implementation: by turning the anti-slip rotating ring 23, the screw 22 is driven to rotate. Since the lifting block 24 is restricted by the outer wall of the housing 1, the lifting block 24 will move upward along the screw 22 after the screw 22 rotates. The lifting block 24 will move together with the rubber top frame 25 until the rubber top frame 25 presses against the roof, thereby sealing the gap between the housing 1 and the roof and effectively preventing water vapor and dust from entering. When the lifting block 24 moves, it will drive the insert block 27 to slide in the inner groove 26. This can effectively restrict the two lifting blocks 24 so that their movement is more stable. The cross bracket 28 can enhance the strength of the housing 1. The bottom of the mounting plate 213 is used to install the lamp body. The lamp cover 29 is also used to seal the bottom of the housing 1. The insert frame 211 is inserted into the airtight groove 212, which can effectively improve the airtightness of the edge of the lamp cover 29. The bolt 210 is used to fix the lamp cover 29.

[0037] Reference Figures 1 to 10 In one aspect of this embodiment, the convenient replacement component 3 includes a top block 31, with an assembly plate 32 fixedly connected to the top of the top block 31. The assembly plate 32 is fixedly connected to the top of a wall. A limit rod 33 is fixedly connected to the top of the cross bracket 28, and the limit rod 33 is inserted into the interior of the top block 31. A slider 34 is slidably connected inside the top block 31. A pin 35 is fixedly connected to one side of the slider 34, and the pin 35 can be inserted into the interior of the limit rod 33. A spring 37 is fixedly connected to the other side of the slider 34, with one end of the spring 37 fixedly connected to the inner wall of the top block 31. A pull rod 36 is fixedly connected to one side of the slider 34, and the pull rod 36 passes through one side of the top block 31 and is movably connected.

[0038] In practice: By fixing the assembly plate 32 to the roof, the overall position of the device is determined. When it is necessary to replace the lamp body on the mounting plate 213 of the sealing component 2, the pull rod 36 can be pulled to move the slider 34. The slider 34 will then move the pin 35 to disengage it from the inside of the limiting rod 33, thereby releasing the restriction on the limiting rod 33 and disassembling the entire sealing component 2 for easy replacement of the lamp body. After the lamp body is replaced, the limiting rod 33 can be reinserted into the top connecting block 31. The spring force applied by the spring 37 will tightly push the pin 35 into the inside of the limiting rod 33, thereby re-fixing it.

[0039] All electrical devices in this plan are powered by an external power source.

[0040] Working Principle: During installation, the lampshade 29 is first fixed to the bottom of the housing 1 using bolts 210. At this time, the insert frame 211 on the top of the lampshade 29 will be inserted into the airtight groove 212 inside the housing 1. With the tight cooperation between the two, the airtightness of the edge of the lampshade 29 is effectively improved, initially blocking the intrusion of moisture and dust from the bottom. Next, by turning the anti-slip rotating ring 23, the screw 22 is rotated. Since the lifting block 24 is restricted by the outer wall of the housing 1 and cannot rotate, it can only move upward along the screw 22, thereby driving the rubber top frame 25 to move upward synchronously until the rubber top frame 25 tightly presses against the roof, sealing the gap between the housing 1 and the roof, further preventing moisture and dust from entering. During this process, when the lifting block 24 moves, it will drive the insert block 27 to slide in the inner groove 26. Through the cooperation between the insert block 27 and the inner groove 26, the movement trajectory of the two lifting blocks 24 is restricted, ensuring smooth movement and reducing shaking, and ensuring the pressing effect of the rubber top frame 25. Meanwhile, the cross bracket 28 on the inner wall of the housing 1 enhances the structural strength of the housing 1, and the mounting plate 213 at its bottom is used to install the lamp body, providing a stable mounting base for the lamp body;

[0041] The entire device is fixed to the roof in a defined position by the assembly plate 32. The limiting rod 33 at the top of the cross bracket 28 is inserted into the top connecting block 31, achieving the initial connection between the sealing assembly 2 and the roof fixing structure. When it is necessary to replace the lamp body on the mounting plate 213, pulling the pull rod 36 causes the slider 34 to slide within the top connecting block 31. As the slider 34 compresses the spring 37, it causes the pin 35 to disengage from the limiting rod 33, releasing the restriction on the limiting rod 33. At this time, the entire sealing assembly 2 can be disassembled and separated for easy replacement of the lamp body. After the lamp body is replaced, the limiting rod 33 is reinserted into the top connecting block 31, the pull rod 36 is released, the spring 37 returns to its original deformation and generates elastic force, pushing the slider 34 back to its original position, causing the pin 35 to be firmly pushed back into the limiting rod 33, completing the re-fixation of the sealing assembly 2 and enabling convenient replacement of the lamp body.
