DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0038] Example 1

[0039] like Figures 1 to 14 As shown, the lighting device of the present invention includes a lighting fixture 2, a movable part 3, a lower base 4 and an upper base 5. The lighting fixture 2 is arranged at the lower end of the movable part 3, the movable part 3 is arranged between the upper base 5 and the lower base 4, and the upper base 5 is located on the lower base 4.

[0040] like Figure 1 As shown, an insertion hole 7 for accommodating the lighting device 1 is provided in the middle of the ceiling 6. The lighting device 1 can be installed on the ceiling 6 by simply pushing the lighting device 1 into the insertion hole 7. When removing the lighting device 1, it can be removed from the insertion hole 7 by simply pushing the lighting device 1 upward again.

[0041] The lamp 2 consists of a lamp body 8 and a lamp cover 9. The lamp body 8 is provided with a first external thread 10, and the lamp cover 9 is provided with a first internal thread 11 that mates with the first external thread 10. A ball head slot 13 is formed in the center of the lamp body 8, which mates with a ball head 12. The lamp cover 9 is provided with a small hole 15 that mates with a second rod 14. The bottom of the small hole 15 is provided with a spherical surface 16 that mates with the ball head 12. By rotating the lamp cover 9, the lamp cover 9 is connected to the lamp body 8, and the ball head 12 is simultaneously restrained in the ball head slot 13 by the lamp cover 9. The lamp 2 can be rotated on the ball head 12 to adjust the illumination angle.

[0042] During installation, first insert the movable part 3 from the bottom of the lamp cover 9, then place it in the middle of the upper base 5 and the lower base 4, then install the limiter 17 to the upper end of the movable part 3, and then match the ball head groove 13 on the lamp body 8 with the ball head 12 for installation, and then match the first external thread 10 on the lamp body 8 with the first internal thread 11 on the cover body for installation.

[0043] The movable member 3 cooperates with the lamp 2, and the lower end of the movable member 3 passes through the lamp cover 9 and is placed in the middle of the lamp body 8. The movable member 3 is composed of a first rod 18, a second rod 14, and a ball head 12 from top to bottom. The diameter of the first rod 18 is smaller than that of the second rod 14. A third through-hole 19 is formed in the middle of the movable member 3 to cooperate with the lamp 2. The third through-hole 19 is used for the connection wire of the lamp 2 to pass through the third through-hole 19 in the middle of the movable member 3 to reach the upper end of the ceiling 6 and connect to the laid external wires.

[0044] A guiding slope 20 is formed between the first rod 18 and the second rod 14 , and the guiding slope 20 cooperates with a retaining member 22 in the limiting assembly 21 .

[0045] The movable member 3 is provided with a first annular groove 24 and a second annular groove 25 that cooperate with the positioning assembly 23 . The first annular groove 24 is located at the upper end of the second annular groove 25 .

[0046] A first annular groove 24 and a second annular groove 25 are provided on the second rod body 14. A first push slope 26 is provided on the first annular groove 24, and a second push slope 27 is provided on the second annular groove 25. The first push slope 26 is adjacent to the second annular groove 25, and the second push slope 27 is adjacent to the first push slope 26. The first push slope 26 and the second push slope 27 are used to cooperate with the push ball 38.

[0047] Since the first annular groove 24 and the second annular groove 25 cooperate with each other, when the positioning assembly 23 cooperates with the second annular groove 25, the movable member 3 is pushed upward, and the positioning assembly 23 maintained in the first annular groove 24 enters the second annular groove 25. When the positioning assembly 23 in the second annular groove 25 needs to enter the first annular groove 24, the movable member 3 can be pulled to move downward. The movable member 3 is then restricted by the limiting member 17, which limits the distance the movable member 3 can be pulled downward, thereby maintaining the positioning assembly 23 from the second annular groove 25 into the first annular groove 24.

[0048] At the same time, a positioning plate (not shown) can be provided on the second rod 14 to cooperate with the limiting plate 28, thereby limiting the distance that the movable member 3 can be pushed upward, ensuring that when the movable member 3 is pushed upward, it is restricted by the positioning plate, thereby achieving rapid positioning. It is ensured that when the positioning plate contacts the limiting plate 28, the positioning assembly 23 is exactly located in the second annular groove 25.

[0049] A stopper 17 is provided at the upper end of the movable member 3. A threaded portion 29 is provided on the first rod 18. The stopper 17 is mounted on the threaded portion 29 to limit the distance the movable member 3 can be pulled downward. The minimum distance of the stopper 17 is greater than the inner diameter of the first through-hole 30 and the second through-hole 31.

[0050] The lower base 4 is disposed on the movable member 3. A first through-hole 30 for accommodating the movable member 3 is defined in the center of the lower base 4. The lower base 4 is disposed at the upper end of the lamp 2 and is located in the center of the ceiling 6. A fixing hole 32 is also defined in the center of the lower base 4. The fixing hole 32 is disposed perpendicularly to and communicates with the first through-hole 30. A positioning assembly 23 is disposed in the fixing hole 32.

[0051] The lower base 4 is composed of a column 33 and a limiting plate 28. The diameter of the limiting plate 28 is larger than that of the column 33, and the fixing hole 32 is provided on the column 33. The diameter of the limiting plate 28 is larger than that of the insertion hole 7, and the diameter of the column 33 matches the insertion hole 7.

[0052] The column 33 is provided with a second external thread 34, and the upper base 5 is provided with a second internal thread 49 that cooperates with the second external thread 34. When the upper base 5 is rotated, the distance between the upper base 5 and the lower base 4 can be changed, thereby ensuring the distance between the retaining member 22 and the limiting plate 28, and adapting to ceilings 6 of different thicknesses.

[0053] The upper base 5 is provided with a guiding inclined surface 35 , which facilitates the insertion and installation in cooperation with the insertion hole 7 .

[0054] Example 2

[0055] The positioning assembly 23 includes a rotating member 36, a first spring 37, and a ball 38. The rotating member 36 is provided with a third external thread 39. The fixing hole 32 is provided with a third internal thread 40 that mates with the third external thread 39. The ball 38 mates with the first annular groove 24 and the second annular groove 25. The ball 38 is kept in position with the first annular groove 24 and the second annular groove 25 to prevent the position of the movable member 3 from changing.

[0056] The upper base 5 is disposed on the lower base 4. A second through-hole 31 is provided in the middle of the upper base 5 to cooperate with the first through-hole 30. The movable member 3 is disposed in the second through-hole 31. A mounting hole 41 is also provided in the middle of the upper base 5, perpendicular to and connected to the second through-hole 31. The mounting holes 41 are located on both sides of the second through-hole 31. A stopper assembly 21 is provided in the mounting hole 41 to cooperate with the suspended ceiling 6.

[0057] The retaining assembly 21 includes a mounting tube 42, a retaining member 22, and a second spring 43. The mounting tube 42 forms an interference fit with the mounting hole 41. A mounting chamber 44 is formed in the center of the mounting tube 42, and a through-hole 45 is provided in the mounting tube 42, communicating with the mounting chamber 44. The retaining member 22 comprises a retaining end 46 and a push end 47. The push end 47 has a tapered surface 48 that mates with the guide ramp 20. The retaining end 46 is positioned within the through-hole 45, and the push end 47 is positioned within the mounting chamber 44. The second spring 43 is positioned over the retaining end 46 and positioned between the through-hole 45 and the push end 47.

[0058] When the pushing end 47 contacts the first rod body 18, the movable part 3 is pushed upward, that is, the installation action of the lighting device 1, and the positioning assembly 23 in the first annular groove 24 is matched with the second annular groove 25. The guiding inclined surface 20 on the movable part 3 pushes the conical surface 48, so that the pushing end 47 is pushed, so that the entire retaining part 22 is movable in the installation chamber 44, and the limiting end 46 is moved out of the through hole 45 and placed on the ceiling 6. By extending the limiting end 46, it is located on the ceiling 6, thereby limiting the position of the lighting device 1.

[0059] When the lighting device 1 needs to be installed, it is only necessary to push the lamp 2 into the insertion hole 7, keep the positioning component 23 from entering the second annular groove 25 from the first annular groove 24, and push the limiting component 21 in the installation hole 41 through the movable part 3, so that the retaining part 22 is placed on the ceiling 6, limiting the position of the lighting device 1 and preventing the lighting device 1 from falling from the insertion hole 7.

[0060] To disassemble, one only needs to pull the lamp 2, causing it to drive the movable member 3 downward, and the retaining positioning assembly 23 to move from the second annular groove 25 into the first annular groove 24. This causes the retaining member 22 to no longer contact the second rod 14 but instead contact the first rod 18. Since the diameter of the first rod 18 is smaller than that of the second rod 14, the second spring 43 pushes the retaining member 22, causing it to enter the installation chamber 44 and break away from the ceiling 6.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
