The spring mounting column 14 is composed of a four-petal column. The end of the column is provided with a hook portion 1421 protruding outward to form a blocking portion. The spring mounting column 142 is sequentially sleeved with a rebound spring 20 and a spring pushing ring 19. The spring pushing ring 19 is provided with a pushing inclined surface 191 on one side facing the bottom of the insulating protection tube 14. A pair of elastic seats 147 cooperating with the spring pushing ring 19 are provided on the bottom wall of the inner cavity of the insulating protection tube 14 on the outer side of the rebound spring 20. Figure 8 As shown, the elastic seat 147 is provided with a guide push inclined surface 1471 that matches the push inclined surface 191, and the elastic seat 147 is provided with a fixed clamping foot 148, and the inner side of the end of the fixed clamping foot 148 is provided with an inner hook 1481, as shown in FIG.

In this embodiment, the insulating protection tube 14 and the spring mounting column 142, the elastic seat 147 and the fixed clamping feet 148 are plastic parts formed by one-time injection molding; the lower mounting tube 9 and the upper mounting tube 12 are both plastic parts.

[0023] In actual application, a pair of spring ears 22 are symmetrically arranged on the side surface of the outer tube 21, and a mounting spring 23 is arranged on the spring ears 22. An input cable 24 is arranged at the bottom of the outer tube 21 through a wire pressing cover 25; a mounting edge is arranged outwardly at the upper edge of the outer tube 21, and a plurality of magnets are usually arranged on the mounting edge along the circumference. A face ring part I composed of a face ring 1, a rubber pad 2, a transparent sheet 3 and a rubber ring 4 is also arranged on the outside of the light-emitting module. The face ring 1 is made of magnetic material. In this way, the entire downlight is arranged into three relatively independent face ring parts I, light-emitting module II and barrel part III - see Figure 2 shown.

[0024] When repairing the downlight using the installation structure of the light-emitting module of the present invention, the face ring part I is first removed, and then the entire light-emitting module II is pressed inward, so that the movable foot 123 installed at the bottom of the upper tube 12 pushes the fixed foot 148 outward and hooks it, and then continues to press inward. The movable foot 123 pushes the spring pushing ring 19 to continuously compress the rebound spring 20. Under the interaction of the pushing inclined surface 191 on the spring pushing ring 19 and the guiding pushing inclined surface 1471 on the elastic seat 147, the elastic seat 47 and the fixed foot 148 connected to the elastic seat 47 are pushed outward, so that the minimum spacing between the inner hooks 1481 of the fixed foot 148 ( The spacing between the inner hook tips of the inner hook 1481 is greater than the maximum spacing between the outer hooks 1231 of the movable foot 123 (the spacing between the outer hook tips of the outer hook 1231). At this time, let go, and the entire light-emitting module II is smoothly ejected for a distance under the action of the rebound spring 20. At this time, the guide block 121 installed on the upper cylinder 12 is still in the rear longitudinal guide groove 145, thereby effectively preventing the light-emitting module II from falling out of the outer cylinder 21. Then, the light-emitting module II is rotated so that the guide block 121 installed on the upper cylinder 12 is located in the front longitudinal guide groove 143, and the light-emitting module II is taken out of the insulating protection cylinder 14 as a whole; for the specific ejection process, see Figures 8 to 12 As shown, the action process of the self-locking rod 15 is shown in Figures 13 to 16 shown.
