[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Example 1:

[0021] Please see Figures 1-4 This utility model provides a technical solution: a surface-mount LED that is easy to assemble and disassemble, including a housing 1, a diode body 2 disposed on one side of the inner wall of the housing 1, a light-emitting component 3 mounted on the upper end of the diode body 2, a light-emitting component 3 mounted on the lower end of the diode body 2, a retaining plate 4 mounted on the lower end of the diode body 2; fixing plates 5 are mounted on both sides of the upper end of the retaining plate 4, a sliding plate 6 is mounted on one side of the fixing plate 5, a first spring 7 is disposed at one end of the sliding plate 6, a first toothed plate 8 is mounted on the other side of one sliding plate 6, a second toothed plate 9 is mounted on the other side of the other sliding plate 6, a limiting plate 10 is mounted on both sides of the first toothed plate 8 and the second toothed plate 9, a gear 11 is mounted on one side of the first toothed plate 8, an extension plate 19 is mounted on both sides of the lower end of the housing 1, and a base plate 20 is mounted on the lower end of the extension plate 19.

[0022] The slide plate 6 is fixedly connected to the fixed plate 5, and the slide plate 6 is slidably connected to the shell 1.

[0023] The first toothed plate 8 is slidably connected to the limiting plate 10, and the second toothed plate 9 is slidably connected to the limiting plate 10. Both the first toothed plate 8 and the second toothed plate 9 are meshed with the gear 11.

[0024] The diode body 2 is fixedly connected to the card plate 4, and the card plate 4 is slidably connected to the housing 1.

[0025] Specifically, when the diode body 2 needs to be installed, the diode body 2 is connected to the card plate 4, and then the card plate 4 is inserted into the housing 1. When the card plate 4 contacts the fixing plate 5, the inclined surface of the card plate 4 will press against the inclined surface of the fixing plate 5, causing the fixing plate 5 to push the sliding plate 6 to slide to both sides. As the sliding plate 6 slides, it will press against the first spring 7. The process stops when the bottom of the card plate 4 is completely in contact with the bottom of the housing 1. At this point, the fixing plate 5 will be positioned above the card plate 4, and then, under the elasticity of the first spring 7, the fixing plate 5 will fix the card plate 4. The installation of diode body 2 is completed. When it is necessary to disassemble diode body 2, rotate gear 11 clockwise to drive the first toothed plate 8 and the second toothed plate 9 to move. At this time, the first toothed plate 8 and the second toothed plate 9 will slide in the limiting plate 10 and squeeze the sliding plates 6 on both sides, so that the fixing plate 5 will lose its fixation on the card plate 4. Then, the diode body 2 and the card plate 4 can be removed. Then, rotate gear 11 counterclockwise to return gear 11 to its original position. This allows the surface mount LED to be quickly installed and removed from diode body 2, making it convenient to replace diode body 2.

[0026] Example 2:

[0027] Please see Figures 1-4 This utility model provides a technical solution: a surface-mount LED that is easy to install and remove. The housing 1 has a mounting bracket 12 that runs through both sides. The mounting bracket 12 has a mounting plate 13 that is installed on both sides. A sliding post 14 is installed at one end of the mounting plate 13. A slider 15 is installed on one side of the sliding post 14. A sliding box 16 is installed on one side of the slider 15. A second spring 17 is provided on the other side of the slider 15. A heat sink 18 is provided at one end of the mounting bracket 12.

[0028] Mounting bracket 12 is slidably connected to housing 1, and mounting bracket 12 is slidably connected to heat sink 18.

[0029] The sliding column 14 passes through the housing 1 and is slidably connected to the housing 1.

[0030] Specifically, by pulling the mounting plate 13, the mounting plate 13 is moved to one side, pulling the mounting bracket 12 to move as well. At the same time, when the mounting plate 13 moves, it will drive the sliding column 14 to move as well, causing the sliding column 14 to pull the slider 15 to slide inside the sliding box 16. Then, when the slider 15 moves, it will compress the second spring 17, thereby changing the distance between the mounting bracket 12 and the housing 1. After adjusting to a suitable distance according to the thickness of the heat sink 18, it stops. Then, the heat sink 18 is put in, and the mounting plate 13 is released. Under the elasticity of the second spring 17, the slider 15 drives the mounting plate 13 back to its original position through the sliding column 14, causing the mounting bracket 12 to push the mounting plate 13 into the housing 1, and making the heat sink 18 fit with the diode body 2. The same process is repeated when removing it, so that the surface mount LED can be quickly installed and removed with the heat sink 18, which facilitates heat dissipation of the diode body 2.

[0031] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
