Furthermore, the bottom of the runway-shaped groove is provided with a strip-shaped groove with the shape matched with the shape and the thickness of the rubber plate, and the bottom of the strip-shaped groove is provided with a plurality of LED lamps arranged at intervals.
Furthermore, a positioning boss is arranged in the concave groove, and a through hole corresponding to the positioning boss in shape is arranged on the key baffle.
Furthermore, the shape of the key is circular, and the key baffle is provided with a sink groove which is tightly matched with the periphery of the key.
Further, the rubber plate is a TPU rubber plate.
The utility model discloses electric tool button waterproof construction's theory of operation: according to the tool, the rubber plate and the decorative plate which are integrally formed in an injection molding mode are overlapped in the runway-shaped groove, the rubber plate is formed in a double-color injection molding mode, the rubber plate has an elastic pressing effect and can rebound, and liquid cannot enter the tool through the position of the key after the rubber plate and the decorative plate are integrally formed in an injection molding mode, so that the waterproof effect of the tool is guaranteed; one side of the rubber plate facing the inside of the plastic shell is provided with a convex button corresponding to the position of the switch key, and the convex button can deform the rubber plate to contact the inside switch key by pressing the key, so that the tool is switched on and off.
Description of the drawings:
FIG. 1 is a schematic perspective exploded view of the present invention;
fig. 2 is a schematic sectional structure of the present invention.
The specific implementation mode is as follows:
in order to make the aforementioned and other features and advantages of the invention more comprehensible, embodiments accompanied with figures are described in detail below.
The utility model discloses electric tool button waterproof construction includes inside plastic casing 1 that is used for holding the electric actuator and establishes runway shape recess 2 on the plastic casing surface, and this plastic casing 1's appearance includes a cylinder physique, toper section and electronic end, and this runway shape recess 2 is established on the cylinder physique.
The tank bottom of runway shape recess 2 is equipped with perforation 3 and wears out fenestrate switch button 4, and this switch button 4 is established on the circuit board that is located plastic casing, the superpose is equipped with integrative injection moulding's rubber slab 5 (the rubber slab is the TPU rubber slab) in runway shape recess 2, and decorative board 6, and this decorative board 6 can be working of plastics or metal stamping workpiece, rubber slab 5 is equipped with the protruding button corresponding with switch button position towards the inside one side of plastic casing (this protruding button is located the back of rubber slab 5 in the picture, fails to show in the picture), be equipped with on the rubber slab depressed groove 7 and inlay the key baffle 8 in the depressed groove, key baffle 8 upper cover is equipped with button 9, be equipped with on the decorative board so that the fretwork hole 10 that key baffle passed.
In order to design reasonably and make the sealing effect better, the groove bottom of the runway-shaped groove is provided with a strip-shaped groove 11 with the shape matched with the shape and the thickness of the rubber plate, the groove bottom of the strip-shaped groove is provided with a plurality of LED lamps 12 arranged at intervals, and the LED lamps 12 are connected with the circuit board.
In order to realize the positioning of the key baffle 8, a positioning boss 13 is arranged in the concave groove, a through hole 14 corresponding to the positioning boss in shape is arranged on the key baffle, and the through hole 14 is matched with the positioning boss 13 to prevent the key baffle from rotating.
The shape of above-mentioned button is circular, be equipped with on the button baffle 8 with button periphery tight fit's heavy groove 15, this heavy groove 15 and button 9 tight fit realize rigid connection between them, when the operator pressed button 9, can transmit the power for rubber slab 5 and switch button 4.
