[0036] During the installation of the embedded ceiling lamp, the lampshade 3 is rotated to make the positioning groove 16 correspond to the positioning block 15, and then the lampshade 3 is pushed into the installation groove 2, and the positioning block 15 will move into the positioning groove 16 to position the lampshade 3. The top of the lampshade 3 will push the ejecting plate 6 and the hanging rod 19 to move upward together. The hanging rod 19 will gradually move into the second sliding groove 17 under the action of the fourth guide groove 18, and the hanging rod 19 will move out of the upper position of the lampshade 3. The upward movement of the ejecting plate 6 will drive the sliding block 5 to move together. After the upper end of the lampshade 3 contacts the ejecting plate 6, the clamping plate 7 will be in the position of the clamping interface 9. During the movement of the sliding block 5, the clamping plate 7 will be driven to move together. The clamping plate 7 will be in the first guide groove 8 moves into the card interface 9, the card plate 7 limits the lampshade 3 to keep the lampshade 3 stable. During the movement of the sliding block 5, the guide rod 13 first moves along the second guide groove 10, and then when the guide rod 13 moves to the first connecting position of the second guide groove 10 and the third guide groove 11, the depth of the third guide groove 11 is shallower than the second guide groove 10, and the guide rod 13 moves along the second guide groove 10 to the bottom of the second guide groove 10, and then the guide rod 13 moves to the connecting position of the second guide groove 10 and the third guide groove 11 and moves to the bottom of the third guide groove 11 beyond the connecting position. The lampshade 3 cannot continue to be pushed into the installation groove 2 due to the restriction of the guide rod 13 and the third guide groove 11. The guide rod 13 will not move into the second guide groove 10 again, and the guide rod 13 will move into the groove 12 along the third guide groove 11, and the lampshade 3 will be in a stable state. The lampshade 3 can be installed and removed quickly and conveniently by pressing, which is conducive to the quick and convenient installation of the embedded ceiling lamp, reducing the installation steps and installation time of the embedded ceiling lamp, and there is no need to disassemble the top plate, etc., reducing additional steps. Subsequently, when the lampshade 3 needs to be disassembled, the lampshade 3 is pushed upward and then slowly released. The guide rod 13 will be in the torsion spring 14 The first guide slot 8 is used to lock the lampshade 3 and the second guide slot 8 is used to lock the lampshade 3. When the lampshade 3 is installed, the second guide slot 8 is used to lock the lampshade 3. When the lampshade 3 is installed, the second guide slot 8 is used to lock the lampshade 3.

[0037] During the installation of the built-in ceiling lamp, after the lampshade 3 is installed, when the lampshade 3 is shaken or pressed upward, it is possible that the lampshade 3 will fall off. As a further solution of the present invention, a third slide groove 21 is provided on the side of the first slide groove 4, and a limit block 22 is elastically slidably connected in the third slide groove 21. The width of the ejection plate 6 and the clamping plate 7 is smaller than the width of the clamping interface 9, and a clearance groove 23 is provided on the side of the positioning groove 16;

[0038] The limiting block 22 will be squeezed into the third slide groove 21 by the side of the lampshade 3 again, the positioning block 15 will move back into the positioning groove 16, and then the lampshade 3 will be pushed upward to remove the lampshade 3.

[0039] During the process of disassembling the lampshade 3, one side of the lampshade 3 will be hung by the hanging rod 19 through the hanging buckle, but the lampshade 3 cannot be dragged upward when disassembling the lampshade 3. The lampshade 3 will fall off directly and swing downward, thereby leaving the position of the hanging rod 19. As a further solution of the present invention, a protrusion 24 is fixedly connected to the surface of the hanging rod 19;

[0040] During the removal of the lampshade 3, the hanging rod 19 and the protruding block 24 will move into the hanging opening 20. Then, when one side of the lampshade 3 is detached from the mounting groove 2, the lampshade 3 on the side away from the scraper rod will flip downward, and the protruding block 24 will block the lampshade 3, thereby preventing the lampshade 3 from directly detaching from the surface of the hanging rod 19 due to shaking after removal, causing the lampshade 3 to fall and be damaged.

[0041] During the installation of the lampshade 3, after the upper end of the lampshade 3 is moved into the installation groove 2, the interior of the lampshade 3 cannot be observed, and the installation position is easily offset. As a further solution of the present invention, the bottoms of the left and right sides of the positioning block 15 are inclined surfaces, and the upper sides of the positioning groove 16 are inclined surfaces;

[0042] During the installation of the lampshade 3, the positioning block 15 can move into the positioning groove 16 through the inclined surfaces on both sides of the upper end of the positioning groove 16, increasing the range in which the positioning groove 16 and the positioning block 15 can guide the positioning of the lampshade 3, reducing the difficulty of installation and ensuring quick installation.

[0043] During the installation of the lampshade 3, when the lampshade 3 moves into the installation groove 2, the position of the lampshade 3 is offset when it is pushed upward, which can easily cause the lampshade 3 to get stuck. As a further solution of the present invention, a plurality of extrusion springs 25 are fixedly connected to the top of the inner wall of the installation groove 2;

[0044] During the installation of the lampshade 3, after the lampshade 3 enters the installation groove 2, the upper end of the lampshade 3 will contact the extrusion spring 25, and then during the upward movement of the lampshade 3, the reaction force of the extrusion spring 25 on the lampshade 3 can push the other side when the upward pushing position of the lampshade 3 is offset, thereby preventing the lampshade 3 from being stuck in the installation groove 2 due to the tilt of the lampshade 3, and the extrusion spring 25 can push out the lampshade 3 that cannot be installed in the installation groove 2, thereby preventing the lampshade 3 from being unable to be installed and unable to automatically fall off from the installation groove 2.

[0045] During the process of disassembling the lampshade 3, dust will be on the surface of the lampshade 3, and dust will fall after disassembly to affect manual operation. As a further solution of the present invention, an annular scraper 26 is fixedly connected to the inner wall surface of the mounting groove 2;

[0046] During the process of disassembling the lampshade 3, the lampshade 3 slowly moves downward from the mounting groove 2, and dust on the surface of the lampshade 3 is scraped off by the scraper 26, so as to prevent the falling dust from affecting the manual operation during the disassembly process.

[0047] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
