DETAILED DESCRIPTION

[0023] During installation, align the LED module 1 with the positioning pin 5 and insert it. At this time, the L-shaped handle 7 is in the initial state. Turn the L-shaped handle 7 to make the connecting rod 6 drive the conical plug 8 to pull down, so that the side wall of the positioning pin 5 separated by the separation groove 9 produces a local tilt expansion, so that the positioning pin 5 has a fixing effect on the LED module 1. At the same time, a pulling force is generated between the L-shaped handle 7 and the conical plug 8, which reduces the installation gap between the LED module 1 and the heat sink 2, making heat transfer more efficient, and increasing the contact area with the air through the heat sink fins 3, greatly improving the heat dissipation effect. During replacement, turn the L-shaped handle 7 to a horizontal position, so that the conical plug 8 moves up, and the expanded outer wall of the positioning pin 5 returns to its initial state, thereby releasing the fixation between the LED module 1 and the heat sink 2, and then realizing the replacement of the LED module 1.

[0024] Specifically, in this embodiment, two positioning holes 10 are provided on the LED module 1 , and two positioning pins 5 are respectively fitted into the corresponding positioning holes 10 . The positioning holes 10 facilitate the installation and positioning of the LED module 1 on the heat sink 2 .

[0025] Specifically, in this embodiment, a first through hole 11 is opened on the bottom end of the mounting block 4 , and the connecting rod 6 is slidably fitted in the first through hole 11 , and the first through hole 11 provides a space for the connecting rod 6 to slide in the mounting block 4 .

[0026] Specifically, in this embodiment, a second through hole 12 is opened on the top of the mounting block 4. The inner diameter of the second through hole 12 is larger than the inner diameter of the first through hole 11 and is connected to the first through hole 11. The second through hole 12 provides space for the connecting rod 6 to slide in the mounting block 4.

[0027] Specifically, in the present embodiment, a rotation groove 13 is opened on one side of the L-shaped handle 7, the connecting rod 6 is located in the rotation groove 13, and a support shaft 14 is arranged between the inner walls on both sides of the rotation groove 13. The support shaft 14 is rotatably installed in the outer wall of the connecting rod 6 near the bottom. The support shaft 14 provides a rotation fulcrum for the L-shaped handle 7, and enables the L-shaped handle 7 to produce a pushing and pulling effect on the connecting rod 6 in the horizontal and vertical states.

[0028] Specifically, in the present embodiment, a conical hole 15 is provided on the top end of the positioning pin 5, and the conical plug 8 is fitted in the conical hole 15. A third through hole 16 is provided on the bottom end of the positioning hole 10. The top end of the third through hole 16 is communicated with the conical hole 15, and the bottom end of the third through hole 16 is communicated with the second through hole 12, and has the same inner diameter as the second through hole 12. Several dividing grooves 9 are communicated with the conical hole 15 and the third through hole 16. The conical hole 15 provides space for the conical plug 8 to move in the positioning pin 5, thereby achieving the effect of tension on the conical plug 8 and expansion of the outer wall of the positioning pin 5.

[0029] Specifically, in the present embodiment, a spring 17 is sleeved on the outer wall of the connecting rod 6, one end of the spring 17 is mounted on the end where the conical plug 8 is connected to the connecting rod 6, and the other end of the spring 17 is mounted on the end where the second through hole 12 is connected to the first through hole 11. When the L-shaped handle 7 is rotated to a vertical state, the spring 17 is compressed, and the reaction force after compression causes the conical plug 8 to tend to move upward. Through the connection with the connecting rod 6, the L-shaped handle 7 in the vertical state is tightly fitted on the bottom end of the mounting block 4, thereby further improving the firmness of the LED module 1 after installation.

[0030] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
