Description

Technical Field

[0001] The utility model relates to the technical field related to a heat dissipation mechanism of a fill light, in particular to a heat dissipation mechanism of a fill light. Background Art

[0002] Since multiple groups of lamp beads are arranged inside the fill light, a large amount of heat will be generated by the lamp beads during lighting. Most existing fill lights use a heat dissipation fan arranged inside the lamp housing to discharge the heat generated by the lamp beads through heat dissipation holes opened on the housing, thereby achieving a heat dissipation effect.

[0003] When the existing fill light is used for a long time, a large amount of dust will be attached to the heat dissipation fan and the heat dissipation holes on the shell. If the dust attached to the heat dissipation holes and the heat dissipation fan is not cleaned in time, the heat dissipation effect of the fill light will be affected. However, the shell and the shell cover of the existing fill light are mostly connected by bolts. When performing the dust cleaning operation, it is necessary to use external tools to tighten the bolts multiple times to disassemble the shell cover. After the dust cleaning is completed, the positioning bolts are tightened with external tools to install the shell cover. The operation is cumbersome and inconvenient to use. In addition, tools are needed to install and disassemble the shell cover, which limits its use. Utility Model Content

[0027] The locking member includes a rotating shaft 9 rotatably mounted on the shell cover 7, a first bevel gear 10 is fixedly mounted on one end of the rotating shaft 9, and a hand wheel is fixedly mounted on the other end extending to the outside of the shell cover 7. Threaded rods 11 are rotatably mounted on the shell cover 7 on both sides of the first bevel gear 10, and a second bevel gear 12 is fixedly mounted on one end of the two threaded rods 11 close to each other. The two second bevel gears 12 are symmetrically distributed on both sides of the first bevel gear 10 and are meshed with the first bevel gear 10. The ends of the two threaded rods 11 away from each other are threadedly mounted with an insert 13, and the insert 13 is threadedly mounted with the socket 14 on the same side.
