[0040] like Figure 1-3 As shown, a rotating fastener 1 comprises: an upper cover 11, the upper cover 11 having a first opening 111 and a first rotating guide piece 112; a base 12 detachably connected to the upper cover 11, the base 12 having a second rotating guide piece 121 extending in the direction of the upper cover 11 and opposite to the first rotating guide piece 112, when the upper cover 11 is connected to the base 12, a rotating guide groove 13 is formed between the first rotating guide piece 112 and the second rotating guide piece 121; a rotating member 14, a part of which is located in the inner cavity enclosed by the upper cover 11 and the base 12, and the rotating member 1 4 extends from the inner cavity through the first opening 111, and one end of the rotating member 14 extending from the inner cavity is provided with a cap 141 extending outward in a direction perpendicular to the axis of the rotating member 14, and the rotating member 14 has a plurality of rotating guide pillars 142 extending outward perpendicular to the axis of the rotating member 14 and arranged around the circumference of the rotating member 14, and the rotating guide pillars 142 are located in the rotating guide groove 13; an elastic member 15, one end of the elastic member 15 abuts against the rotating member 14, and the other end of the elastic member 15 abuts against the base 12, and the elastic member 15 can be a spring, for example. The rotating member 14 includes a first rotating member 143, a second rotating member 144, and a connecting unit 145 for connecting the first rotating member 143 and the second rotating member 144, such as a screw or a bolt, the connecting unit 145 passes through the second rotating member 144 and is connected to the first rotating member 143, and the rotating guide pillars 142 are located on the second rotating member 144.

[0041] like Figure 1-3 As shown, the first rotating guide plate 112 and the second rotating guide plate 121 respectively have convex portions 1121, 1211 and concave portions 1122, 1212 adjacent to the convex portions 1121, 1211, the convex portions 1121, 1211 and the concave portions 1122, 1212 adjacent to each other, the convex portion 1121 of the first rotating guide plate 112 is opposite to the concave portion 1212 of the second rotating guide plate 121, and the concave portion 1122 of the first rotating guide plate 112 is opposite to the convex portion 1211 of the second rotating guide plate 121, when the rotating member 14 is pressed down, the rotating guide column 142 will move from the concave portion 1122 of the first rotating guide plate 112 to the concave portion 1212 of the second rotating guide plate 121, and when the rotating member 14 is released, the rotating guide column 142 will move from the concave portion 1212 of the second rotating guide plate 121 to the other concave portion 1122 of the first rotating guide plate 112. The convex portion 1121 and the concave portion 1122 of the first rotation guide blade 112 and the convex portion 1211 and the concave portion 1212 of the second rotation guide blade 121 enclose a rotation guide groove 13 .

[0042] like Figure 1 As shown, the rotating guide pillars 142 are symmetrical with respect to the axis of the rotating member 14. The first rotating guide blade 112 and the second rotating guide blade 121 have four convex portions 1121, 1211 and four concave portions 1122, 1212 respectively, and the axes of two adjacent rotating guide pillars 142 form a 90° angle.

[0043] like Figure 1 As shown, one end of the first rotating member 143 close to the second rotating member 144 has a plurality of connecting grooves 1431, and one end of the second rotating member 144 close to the first rotating member 143 has connecting wings 1441 matching the connecting grooves 1431. Alternatively, one end of the first rotating member 143 close to the second rotating member 144 has a plurality of connecting wings, and one end of the second rotating member 144 close to the first rotating member 143 has a connecting groove matching the connecting groove.

[0044] like Figure 4 , 6 As shown in Figure 8, an LED lamp assembly includes: a rotating fastener 1; a light source assembly 2, the light source assembly 2 includes a light source board 21 and a substrate 22 for supporting the light source board 21; and a mounting seat 3, the mounting seat 3 has a receiving space 31 for receiving the light source assembly 2; wherein the substrate 22 is connected to the rotating fastener 1, and the mounting seat 3 includes a first connecting portion 32 that is engaged with the cap 141 of the rotating fastener 1. Both sides of the substrate 22 have fins 221 that slowly extend outward. The inner side of the receiving space 31 of the mounting seat 3 includes two opposite second connecting portions 33, and the two second connecting portions 33 are respectively engaged with the fins 221. The first connection part 32 includes a channel 321 for the rotation member 14 and its cap 141 to pass through. The channel 321 has a first width d1. The first connection part 32 is configured such that when the rotation member 14 is released, the second width d2 of the cap 141 in the width direction of the channel is greater than the first width d1. At this time, the rotation member 14 of the rotary fastener 1 is in a locked state, and the cap 141 cannot pass through the channel of the first connection part 32. When the rotation member 14 is pressed down, the third width d3 of the cap 141 in the width direction of the channel is less than the first width d1. At this time, the rotation member 14 of the rotary fastener 1 is in an unlocked state, and the cap 141 can pass through the channel of the first connection part 32.

[0045] The following describes in detail the installation and removal process of the LED lamp assembly:

[0046] like Figure 5As shown, the downward arrow indicates that the rotating member 14 of the rotating fastener 1 is pressed down, and the upward arrow indicates that the rotating member 14 of the rotating fastener 1 is released. When the rotating member 14 is pressed down, the rotating guide post 142 will move from the recess 1122 of the first rotating guide piece 112 to the recess 1212 of the second rotating guide piece 121. At this time, the position of the rotating member 14 is lower than the position in the initial state, and the cap 141 rotates 45 degrees relative to the position in the initial state. When the rotating member 14 is released, the rotating guide post 142 will move from the recess 1212 of the second rotating guide piece 121 to the other recess 1122 of the first rotating guide piece 112. At this time, the rotating member 14 continues to rotate 45 degrees, which is equivalent to a 90-degree rotation of the position in the initial state.

[0047] like Figure 6 As shown, when the light source assembly 2 needs to be installed in the mounting seat 3, the light source assembly 2 is directly pressed into the accommodating space 31 of the mounting seat 3 and pressed to the bottom. At this time, the cap 141 of the rotating member 14 of the rotating fastener 1 is pressed and rotated, so that the second width of the cap 141 in the width direction of the channel 321 is smaller than the first width (that is, the width of the channel 321), and the cap 141 can pass through the channel 321 of the first connecting portion 32. Then, the rotating fastener 1 is released, and the rotating member 14 of the rotating fastener 1 will rotate 90°, so that the third width of the cap 141 in the width direction of the channel 321 is larger than the first width (that is, the width of the channel 321), so that the cap 141 is stuck in the first connecting portion 32.

[0048] like Figure 7 and 8 As shown, when the light source assembly 2 needs to be removed from the mounting base 3, the light source assembly 2 is pressed to the bottom, so that the cap 141 of the rotating member 14 is pressed and rotated, so that the second width of the cap 141 in the width direction of the channel 321 is smaller than the first width (that is, the width of the channel 321), so that it can pass through the channel 321 of the first connecting portion 32.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
