[0003] In current technology, ceiling light fixtures in some residences, offices, and shopping malls typically consist of two parts: a supporting shell and a protective cover. During installation, plastic clips are commonly used to tightly connect the supporting shell and the protective cover. This connection method provides a certain degree of sealing and is waterproof and dustproof, effectively extending the lifespan of the lamp core.

[0004] However, some plastic lampshades have a separate support shell and protective cover design. During subsequent use, if it's necessary to replace the lamp core or clean the plastic lampshade, the protective cover must be disassembled and set aside before cleaning the inside of the lampshade can be carried out. This design is difficult and inconvenient for plastic lampshades installed at high locations, making it impractical in actual use. Therefore, to address these issues, a waterproof and dustproof sealed plastic lampshade is proposed. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Specific implementation examples are given below.

[0027] Please see Figure 1 - Figure 6This utility model provides a waterproof and dustproof sealed plastic lampshade, including a supporting shell 1; a protective cover 2 is in contact with the bottom of the supporting shell 1; a fixing block 3 is fixedly connected to the side wall of the supporting shell 1; a rotating cylinder 31 is rotatably connected to the middle of the fixing block 3; a sliding rod 34 is slidably connected to the inner wall of the rotating cylinder 31; a fixing plate 32 is fixedly connected to the bottom of the sliding rod 34; a pull handle 33 is fixedly connected to the bottom of the fixing plate 32; the side wall of the sliding rod 34 is fixedly connected to the side wall of the protective cover 2; a spring 37 is fixedly connected to the inner wall of the sliding rod 34; The top of the spring 37 is fixed to the inner wall of the rotating cylinder 31; a fixing ring 42 is fixed to the top of the protective cover 2; a sealing ring 41 contacts the side wall of the fixing ring 42; a sealing groove 5 is provided on the inner wall of the support housing 1; the sealing ring 41 contacts the inner wall of the sealing groove 5. During operation, when it is necessary to open the protective cover 2 to inspect or clean the lamp wick inside the support housing 1, simply pull the handle 33. The handle 33 will drive the fixing plate 32 and the protective cover 2 to move synchronously, and the protective cover 2 will drive the fixing ring 42 and the... The sealing ring 41 moves synchronously. Being made of rubber, the sealing ring 41 is elastic and deforms under pressure from the inner wall of the supporting housing 1 during movement, ensuring it can smoothly detach from the inner wall of the sealing groove 5. Simultaneously, the fixing plate 32 drives the sliding rod 34 to slide along the inner wall of the rotating cylinder 31. The sliding rod 34 also stretches the spring 37 until the protective cover 2 is fully open. At this point, the protective cover 2 can be rotated, rotating around the center of the rotating cylinder 31 until it is fully rotated to one side of the supporting housing 1. Then, the handle 33 can be released, and the spring 37 will pull the sliding rod 34 back to its original position. The fixing ring 42 will then be positioned on the bottom surface of the supporting housing 1, preventing the protective cover 2 from rotating back to its original position. This allows the user to inspect the lamp core without being affected by the protective cover 2, ensuring the entire process is safer than traditional methods that require repeated disassembly and reassembly of the protective plate, thus improving user safety during high-altitude operations.

[0028] Furthermore, such as Figure 2 - Figure 3 and Figure 6As shown, the top of the fixing ring 42 contacts the circular ring 4; a rectangular shell 44 is fixedly connected to the inner wall of the circular ring 4; a push plate 47 is slidably connected to the inner wall of the rectangular shell 44; a locking block 48 is fixedly connected to the side wall of the bottom end of the push plate 47; a limiting shell 45 is fixedly connected to the inner wall of the fixing ring 42; the bottom of the push plate 47 contacts the inner wall of the limiting shell 45; a limiting groove 49 is formed on the inner wall of the limiting shell 45; the locking block 48 contacts the inner wall of the limiting groove 49; a positioning ring 43 is fixedly connected to the bottom of the circular ring 4; the positioning ring 43 is inserted into the inner wall of the top end of the sealing ring 41. During operation, after the sealing ring 41 has been used for a period of time, aging problems may occur, and it needs to be replaced. The push plate 47 drives the locking block 48 to move until the locking block 48 disengages from the inner wall of the limiting groove 49. At this point, the push plate 47 can pull the ring 4 to remove the ring 4. The ring 4 will drive the positioning ring 43 to move, causing the positioning ring 43 to disengage from the inner wall of the sealing ring 41. Then the sealing ring 41 can be removed. When installing a new sealing ring 41, it needs to be placed on the side wall of the fixing ring 42, and then the ring 4 is placed on top. During this process, the push plate 47 will insert into the inner wall of the limiting shell 45 and cause the locking block 48 to lock into the inner wall of the limiting groove 49. This completes the disassembly and assembly of the sealing ring 41, ensuring the stability of the sealing ring 41 while enabling its quick replacement, thus improving its practicality.

[0029] Furthermore, such as Figure 5 As shown, the inner wall of the rotating cylinder 31 is provided with a sliding groove 36; a slider 35 is fixedly connected to the side wall of the sliding rod 34; the slider 35 is slidably connected to the inner wall of the sliding groove 36. During operation, when the sliding rod 34 slides on the inner wall of the rotating cylinder 31, it will drive the slider 35 to slide on the inner wall of the sliding groove 36. Through the cooperation between the slider 35 and the sliding groove 36, it is ensured that when the protective cover 2 is rotated, it can smoothly and stably drive the rotating cylinder 31 to rotate through the sliding rod 34, thus improving practicality.

[0030] Furthermore, such as Figure 2 and Figure 5 As shown, the fixed block 3 has an annular groove 39 in the middle; the top side wall of the rotating cylinder 31 is rotatably connected to a ball bearing 38; the ball bearing 38 rolls on the inner wall of the annular groove 39. When the rotating cylinder 31 rotates, it will drive multiple sets of ball bearings 38 to roll on the inner wall of the annular groove 39. Through rolling friction, the friction between the rotating cylinder 31 and the fixed block 3 can be reduced, and the smoothness of the rotation of the protective cover 2 can be improved.

[0031] Furthermore, such as Figure 3As shown, the side wall of the locking block 48 is provided with an inclined surface. During operation, the inclined surface ensures that when the push plate 47 is inserted into the inner wall of the limiting shell 45, the limiting shell 45 will be pushed along the inclined surface of the locking block 48 to move, so that the ring 4 and the fixing ring 42 can be quickly installed, improving convenience.

[0032] Furthermore, such as Figure 3 As shown, a second spring 46 is fixedly connected to the side wall of the push plate 47; the end of the second spring 46 is fixedly connected to the inner wall of the ring 4. When working, the second spring 46 has a certain elasticity, ensuring that when the ring 4 and the fixed ring 42 are installed together, the second spring 46 can push the push plate 47 through its own elasticity so that the locking block 48 is always locked in the inner wall of the limiting groove 49, ensuring the stability of its limiting.

[0033] Furthermore, such as Figure 3 As shown, multiple sets of positioning rings 43 are provided; multiple sets of positioning rings 43 are fixed to the top of the fixed ring 42; multiple sets of positioning rings 43 are inserted into the inner wall of the bottom end of the sealing ring 41. During operation, the multiple sets of positioning rings 43 can limit the upper and lower positions of the sealing ring 41, reduce the risk of slippage, and ensure its stability.

[0034] Working principle: When it is necessary to open the protective cover 2 to inspect or clean the lamp wick inside the support housing 1, simply pull the handle 33. The handle 33 will drive the fixing plate 32 and the protective cover 2 to move synchronously. The protective cover 2 will drive the fixing ring 42 and the sealing ring 41 to move synchronously. The sealing ring 41 is made of rubber and has a certain degree of elasticity. Therefore, it will be deformed by the pressure of the inner wall of the support housing 1 during movement, ensuring that it can smoothly detach from the inner wall of the sealing groove 5. At the same time, the fixing plate 32 will drive the sliding rod 34 to slide on the inner wall of the rotating cylinder 31, and the sliding rod 34 will stretch the spring 37 until the protective cover 2 is fully opened. Then the protective cover 2 can be rotated. The protective cover 2 will rotate around the center of the rotating cylinder 31 and drive the rotating cylinder 31 to rotate until the protective cover 2 is completely rotated to one side of the support housing 1. At this time, the handle 33 can be released. The spring 37 will pull the slide rod 34 and the protective cover 2 to reset through its own elasticity. At this time, the position of the fixing ring 42 will operate the bottom surface of the support housing 1, so the protective cover 2 cannot rotate back to the position that coincides with the support housing 1. The user can then inspect the lamp wick without being affected by the protective cover 2. This ensures that the entire process does not require repeated disassembly and installation of the protective plate as in the traditional method, thus improving the safety of the user when working at height.

[0035] After a period of use, the sealing ring 41 may age and need to be replaced. To do this, push the push plate 47 to move the locking block 48 until it disengages from the inner wall of the limiting groove 49. Then, pull the ring 4 with the push plate 47 to remove it. The ring 4 will move the positioning ring 43, disengaging it from the inner wall of the sealing ring 41. The sealing ring 41 can then be removed. When installing a new sealing ring 41, it needs to be fitted onto the fixing ring 4. The side wall of ring 4 is then covered with ring 4. During this process, the push plate 47 will be inserted into the inner wall of the limiting shell 45. The limiting shell 45 will be pushed along the inclined surface of the locking block 48 to move. The locking block 48 will drive the push plate 47 to move and squeeze the second spring 46 until the locking block 48 overlaps with the limiting groove 49. At this time, the second spring 46 will push the push plate 47 to reset through its own elasticity, so that the locking block 48 is locked in the inner wall of the limiting groove 49, ensuring that the ring 4 and the fixing ring 42 can be quickly installed, improving convenience.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
