[0003]

[Problems to be solved by the invention]

 However, the gear box cover 12 and the end cover 14 of the electric fan described above are fixed or removed using screws 15. This mounting method using screws is expensive for the manufacturer, and requires a tool (driver) for the user to remove it, making the operation inconvenient and incompatible with the tide of the times.

[0004] Therefore, an object of the present invention is to improve an inconvenient assembling method using screws and to provide a gear box lid that can be easily attached to a gear box without tools.

[0005]

[Means for Solving the Problems]

 According to the gearbox lid of the electric fan according to the first aspect of the present invention, the end lid is provided with projecting plates at both ends. The protruding plate is provided with a vertical cut. Further, the gear lid has a vertical plate, and the vertical plate is formed with a hook. When assembling the end cover to the gear cover, push the protruding plate of the end cover into the inside of the vertical plate of the gear cover, and fit the hook of the vertical plate into the cutout of the protruding plate, so that the end cover is securely engaged with the gear. Assembled and fixed to the lid. To remove the end cover from the gear cover, pull the vertical plate outward and remove the hook from the cut edge of the protruding plate, and the end cover can be easily removed from the gear cover.

[0006] The cutouts of the protruding plates on both sides of the end cover can be easily fitted to the hooks of the gear cover, so that the end cover can be manually assembled to or removed from the gear cover without using any tools. Or it is possible.

[0007]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. The gearbox lid of the electric fan according to the present invention includes a gearbox lid 2 and an end lid 3 as shown in FIG.

The gear box cover as a gear cover of the electric fan is of a type in which a switch is provided at the rear end of the outer shell 16 as shown in FIGS. A gear box lid 12 is provided at the rear end of the gear box 11. After the power cord 13 is connected and passes through the gearbox lid 12, the end lid 14 is fixed to the gearbox lid 12 with screws 15. The other end of the power cord 13 is connected to a swivel button switch 17 at the end of the outer shell 16 after passing through the end cover 14. This switch 17 is used by the user to adjust the required wind speed.

The gear box lid 2 has a top plate 21, a protruding plate 22 provided on the top plate 21, and a hook 23 provided immediately adjacent to the protruding plate 22. The protruding plate 22 is assembled to the pull rod 18 of the head, and the bottom of the gear box lid 2 is fixed to the gear box 11. The gearbox lid 2 is further formed with two vertical plates 24 which are vertically parallel at both ends on the rear side, and each vertical plate 24 has several U-shaped notches. The power cord 13 is inserted between these holes 25 so that it can conform to the S mark and safety standards. Further, each vertical plate 24 is provided with a hook 26 at an intermediate portion thereof.

The end cover 3 has several vertical plates 31 on both sides, and each vertical plate 31 has several holes 32 formed therein. The power cord 13 of the switch 33 provided with the hole 32 on the rear side of the end cover 3 passes through. Further, a protruding plate 34 is provided in the middle of each vertical plate 31, and the protruding plate 34 is formed with a vertical cut 35. The end cover 3 can be easily assembled and fixed to the gear box cover 2 by fitting the cut 35 to the hook 26 of the gear box cover 2.

Next, a description will be given with reference to FIGS. When the end cover 3 is directly attached to the rear end of the gear box cover 2, that is, the vertical plate 31 of the end cover 3 is pushed into the inside of the vertical plate 24 of the gear box cover 2, and the hook 26 and the cutout 35 are connected. By fitting, the end lid 3 is directly fixed to the gearbox lid 2 and there is no need to use any tools. When the end cover 3 is to be removed from the gear box cover 2, the end cover 3 can be easily removed by pulling the handle 26 outward and removing the end cover 3 from the cutout 35. When assembling and removing the end cover 3 and the gear box cover 2, the power cord 13 is sandwiched in the U-shaped notch 25 of the gear box cover 2, so that it does not hinder the work.

[0012] The assembly and removal of the gearbox cover and the end cover of the present invention do not require any ordinary tools or specific tools, and the removal operation for combination or inspection is easy, and work can be performed even by a non-skilled worker. In addition, it can conform to the safety standard of S mark.
