[0028] Reference Figure 1-Figure 4 According to an embodiment of the utility model, an easy-to-clean and detachable spotlight radiator includes a barrel 11, a downwardly opening receiving groove 12 is provided in the barrel 11, and the receiving groove 12 is used to install the light-emitting unit, which generates heat when working. In order to facilitate heat dissipation, the upper side surface of the barrel 11 is an inclined surface 13, and a plurality of groups of heat dissipation fins 14 are provided on the inclined surface 13 at equal angles on the left and right. The setting of the inclined surface and the heat dissipation fins 14 is beneficial to cooling the inside of the receiving groove 12.

[0029] To facilitate cleaning, the heat sink fins 14 are designed to be detachable, that is, the inclined surface 13 is provided with a plurality of installation grooves 15 that penetrate upward to accommodate the heat sink fins 14, and the cylinder 11 is provided with a locking mechanism for pressing the heat sink fins 14 located in the installation grooves 15.

[0030] In this embodiment, the locking mechanism includes a slide groove 16 arranged in the side of each of the mounting grooves 15, and a through hole penetrating all the slide grooves 16 and the mounting grooves 15 is provided in the cylinder 11. A threaded shaft 17 passing through all the through holes is rotatably connected in the cylinder 11, and a through groove for accommodating the threaded shaft 17 is provided in the bottom surface of the heat dissipation fin 14. A pressure plate 18 is slidably connected in the slide groove 16, and the pressure plate 18 is threadedly connected to the threaded shaft 17, and the threaded shaft 17 extends to the outside of the cylinder 11, and a handle 19 is fixed to the end of the threaded shaft 17.

[0031] When the heat sink fin 14 needs to be locked, the staff inserts the heat sink fin 14 downward into the mounting groove 15. At this time, the position of the through groove in the heat sink fin 14 is just matched with the threaded shaft 17. Then, the handle 19 is rotated to make the pressure plate 18 move horizontally, thereby pressing the heat sink fin 14.

[0032] In order to make the heat dissipation fin 14 more stable when being pressed by the pressure plate 18, a slot 20 for accommodating the pressure plate 18 is provided in the side of the heat dissipation fin 14, and the depth of the slot 20 is not greater than the left and right widths of the pressure plate 18, that is, the pressure plate 18 can act as a latch when entering the slot 20 to prevent the heat dissipation fin 14 from escaping from the mounting slot 15.

[0033] In the second embodiment of the easy-to-clean and detachable spotlight radiator, it also includes a boss 21. The inclined surface 13 is also provided with a socket connected to the accommodating groove 12. The boss 21 is vertically inserted into the socket. The boss 21 is provided with a wire groove 24 that passes through from top to bottom. The wire harness connected to the light-emitting unit in the accommodating groove 12 can pass through the wire groove 24.

[0034] In order to facilitate the fixing of the boss 21, a positive locking plate 22 pressed against the boss 21 is integrally formed on the middle heat dissipation fin 14, and lateral locking plates 23 pressed against the boss 21 are integrally formed on the heat dissipation fins 14 located on the left and right sides of the positive locking plate 22.

[0035] With such a design, when installation is required, the staff first presses the boss 21 into the socket, and then vertically installs each of the heat sink fins 14. At this time, the boss 21 is locked in position by the heat sink fins 14. Thereafter, the staff rotates the knob 19 so that both the heat sink fins 14 and the boss 21 are locked in position.

[0036] In order to arrange the wires neatly, a wire buckle 25 is also installed in the wire groove 24.

[0037] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
