[0023] Specifically, the mounting outer ring 4 is composed of a front outer ring 41 and a rear outer ring 42, the first limiting ring 411 is formed on the front outer ring 41, the second limiting ring 421 is formed on the rear outer ring 42, an annular step 62 is provided on the rear end of the side surface of the sliding seat 6, the limiting ring 61 is placed on the annular step 62, and a pressure plate 63 for clamping the limiting ring 61 is fixed to the rear end of the sliding seat 6 by screws.

[0024] Specifically, the structure of the splicing of the front outer ring 41 and the rear outer ring 42: a plurality of connecting feet 422 are formed on the side surface of the rear outer ring 42, and a plurality of connecting grooves 412 matching the connecting feet 422 are opened on the front outer ring 41. The connecting feet 422 are placed in the connecting grooves 412 and fixedly connected to the front outer ring 41 by screws. The cooperation between the connecting feet 422 and the connecting grooves 412 plays a positioning role for the splicing of the front outer ring 41 and the rear outer ring 42, thereby ensuring the accuracy and stability of the splicing of the front outer ring 41 and the rear outer ring 42.

[0025] Specifically, in order to improve the heat dissipation performance of the spotlight, a partition 51 is formed on the inner wall of the telescopic inner ring 5, and the partition 51 divides the internal space of the telescopic inner ring 5 into an installation space 52 located at the front and a heat dissipation space 53 located at the rear. The bracket 1 is fixedly connected to the partition 51, so that the light source, the bracket 1, the lens 2 and the mask 3 are arranged in the installation space 52. A plurality of heat dissipation fins 54 located in the heat dissipation space 53 are formed on the partition 51, and a sealing plate 55 is fixedly connected to the rear port of the telescopic inner ring 5, and a plurality of heat dissipation holes 551 are opened on the sealing plate 55.

[0026] In the above embodiment, the spotlight is fixedly installed on the installation position such as the ceiling of the house by installing the outer ring 4. Under normal circumstances, the telescopic inner ring 5 extends into the installation outer ring 4, and the sliding seat 6 is limited by the interference fit between the limiting ring 61 and the inner wall of the installation outer ring 4, so that the telescopic inner ring 5 and the sliding seat 6 are stably maintained in the installation outer ring 4 to achieve the lighting effect. When the irradiation height of the spotlight needs to be adjusted, the telescopic inner ring 5 is pinched through the gap between the front end of the telescopic inner ring 5 and the front end of the installation outer ring 4. The front end of the ring 5 pulls the telescopic inner ring 5 outward, and the telescopic inner ring 5 drives the sliding seat 6 to slide outward in the installation outer ring 4, so as to adjust the length of the telescopic inner ring 5 extending out of the installation inner ring and adjust the irradiation height of the spotlight, so as to meet the lighting height requirements of different users and make the spotlight more practical. In the process of the sliding seat 6 sliding with the telescopic inner ring 5 in the installation outer ring 4, the limiting ring 61 always maintains an interference fit with the inner wall of the installation outer ring 4, and applies a limit to the sliding seat 6 after the sliding seat 6 slides into place to ensure the stability of the sliding seat 6 after it slides into place. To ensure the stability of the telescopic inner ring 5 after it is telescoped into place, the first limiting ring 411 and the second limiting ring 421 apply a limit to the sliding stroke of the sliding seat 6 in the installation outer ring 4, so that the sliding seat 6 remains in the installation outer ring 4 to slide, thereby ensuring the lighting effect after the telescopic inner ring 5 is telescoped and adjusted, and the installation outer ring 4 is divided into a front outer ring 41 and a rear outer ring for splicing, so that the sliding seat 6 is conveniently taken out from the installation outer ring 4, and after the sliding seat 6 is taken out from the installation outer ring 4, the pressing plate 6 is removed. 3, the limiting ring 61 can be disassembled and assembled, so that the limiting ring 61 can be replaced after being worn out due to long-term sliding, so as to ensure that the limiting ring 61 maintains an interference fit with the mounting outer ring 4, thereby ensuring the limiting effect of the limiting ring 61 on the sliding seat 6 and the telescopic inner ring 5, and ensuring the stability of the telescopic inner ring 5 after it is telescoped into place, and the heat dissipation fins 54 arranged in the heat dissipation space 53 and the heat dissipation holes 551 opened on the sealing plate 55 play a good heat dissipation role for the light source during operation, thereby ensuring the stability of the spotlight during operation.

[0027] Furthermore, the structure of the telescopic inner ring 5 connected to the sliding seat 6: the partition plate 51 is fixedly connected to a swing seat 56 located in the heat dissipation cavity, the sealing plate 55 is provided with a first notch 552 opposite to the swing seat 56, the sliding seat 6 is formed with a support arm 67 extending into the heat dissipation cavity through the first notch 552, the swing seat 56 is rotatably connected to the support arm 67, and the side wall of the heat dissipation cavity is provided with a second notch 57 located on one side of the support arm 67 and through which the support arm 67 can pass.

[0028] In the above preferred embodiment, after pulling the telescopic inner ring 5 so that the telescopic inner ring 5 is completely separated from the mounting outer ring 4, the telescopic inner ring 5 is moved to make the swing seat 56 swing on the support arm 67 to adjust the angle of the telescopic inner ring 5, thereby adjusting the illumination angle of the spotlight to meet the needs of different users for the lighting angle, so that the spotlight has better practicality, and the first notch 552 and the second notch 57 provide a swinging space for the telescopic inner ring 5 to swing on the support arm 67 with the swing seat 56, so that the swing amplitude of the telescopic inner ring 5 on the support arm 67 can reach a maximum of 90 degrees, so that the spotlight has a larger adjustment amplitude of the illumination angle to better meet the needs of different users for the illumination angle.

[0029] Preferably, the interior of the sliding seat 6 is hollow, and a first wire threading groove 64 is provided on the front end surface of the sliding seat 6, the first wire threading groove 64 is arranged through the support arm 67, a second wire threading groove 65 is provided on the pressure plate 63, and a wire pressing plate 66 is arranged in the sliding seat 6. The wiring of the light source passes through the partition 51 and extends into the heat dissipation space 53, and then passes through the second wire threading groove 65 and the first wire threading groove 64 in turn to pass out of the mounting outer ring 4. The wiring that passes through the second wire threading groove 65 and extends into the sliding seat 6 is clamped and fixed by the wire pressing plate 66, ensuring that the wiring of the light source remains relatively fixed with the light source when the sliding seat 6 and the telescopic inner ring 5 move, avoiding the wiring of the light source from falling off the light source, thereby ensuring the stability of the spotlight when it is working.

[0030] Preferably, a positioning groove 553 is formed on the rear end surface of the sealing plate 55, and a positioning column 68 that can be abutted against the bottom of the positioning groove 553 is formed on the front end surface of the sliding seat 6. When the telescopic inner ring 5 is reset and swung toward the sliding seat 6, the positioning column 68 extends into the positioning groove 553 and abuts against the bottom of the positioning groove 553, thereby limiting the reset swing of the telescopic inner ring 5, so that the telescopic inner ring 5 and the sliding seat 6 are kept on the same axis, which is convenient for extending the telescopic inner ring 5 to the sliding seat 6 into the mounting outer ring 4. After the telescopic inner ring 5 is extended into the mounting outer ring 4, a gap is created between the sealing plate 55 and the sliding seat 6 through the action of the positioning column 68, thereby ensuring the passability of the heat dissipation hole 551, thereby ensuring the heat dissipation effect on the spotlight when the heat dissipation hole 551 cooperates with the heat dissipation fins 54, and ensuring the stability of the spotlight when it is working.

[0031] 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, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
