Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-7, the present invention provides a technical solution: the utility model provides a waterproof headlight button that is difficult for droing, includes circuit board 1, and display lamp 101 and two sets of switch 102 are installed to 1 upper end of circuit board, stopper 2 in the switch 102 upper end is installed, 2 externally mounted have silica gel cap 3 in the stopper, screw hole site 103 has been seted up on circuit board 1, is convenient for with circuit board 1 fixed mounting on the shell.

The vertical through-hole of having seted up in interior stopper 2 middle part, switch 102 upper end stretches into in the through-hole, is convenient for overlap interior stopper 2 in the switch 102 outside, equal integrated into one piece in both ends is provided with boss 201, upper end about the interior stopper 2 outer lane the boss 201 up end outside is equipped with inclined plane 202, interior stopper 2 upper end is the arc, 3 lower extremes of silica gel cap are the opening form, 3 interior tops of silica gel cap be equipped with the upper end boss 201 assorted recess, space and interior stopper 2 lateral wall phase-match between the 3 lateral walls of silica gel cap, because the 3 caps of silica gel cap have elasticity, the interior stopper 2 that has boss 201 can be followed 3 lower extremes of silica gel cap and is stuffed into in silica gel cap 3 equally, because the boss 201 up end outside of upper end is equipped with inclined plane 202, reduce the resistance when interior stopper 2 is stuffed into 3 to silica gel cap 3, after in the recess at top was arrived to boss 201 to silica gel cap 3 interior stopper, the silica gel cap 3 lateral wall retracted, thereby with interior stopper 2 tight fit in silica gel cap 3 for 3 is difficult for the lug 2 is difficult for drop, and the boss 201 of interior stopper is located the 3 lower extreme is located the boss, carries out the lower extreme of silica gel cap, carries out further tight fit.
