The specific embodiment
Lift a preferred embodiment below, and come the clearer the present invention that intactly illustrates by reference to the accompanying drawings.
As shown in Figure 1 to Figure 3, the electric tool with rotatable many lamps light structures provided by the invention comprises an interconnective instrument casing 1 and a torsion cap assemblies 2.Torsion cap assemblies 2 comprises torsion lid inner ring 21, torsion lid outer ring 22, clear lamp baffle 23 and torsion lid front shroud 24.Torsion cap assemblies 2 is provided with a lighting device 3, and lighting device 3 comprises metal spring leaf 34 in copper band 32 in the LED lamp driver plate 31,, the outer copper band 33,, an outer metal spring leaf 35, an interior elastic contact chip 36, an outer elastic contact chip 37 and some LED lamps 38.Instrument casing 1 is provided with a tool switch 11.Certainly, it will be appreciated by those skilled in the art that herein interior copper band 32 and outer copper band 33 are a kind of giving an example, also can adopt the conductive ring of other materials; Interior metal spring leaf 34 and outer metal spring leaf 35 also are a kind of giving an example, and also can adopt the conductive reed of other materials; Interior elastic contact chip 36 and outer elastic contact chip 37 then are that a kind of of elastic conducting strip gives an example; LED lamp 38 can also replace with laser head or neon lamp.
Wherein, interior copper band 32 is installed in the rear end of torsion lid inner ring 21, and outer copper band 33 is installed in the rear end draw-in groove of torsion lid outer ring 22.Some LED lamps 38 are installed on the LED lamp driver plate 31; and be installed in the front end of torsion lid inner ring 21; clear lamp baffle 23 is equipped with in the outside; the zone of corresponding LED lamp 38 is transparent region on the clear lamp baffle 23, by the assembling of torsion lid front shroud 24 torsion is covered inner ring 21, torsion lid outer ring 22 and clear lamp baffle 23 and combines composition torsion cap assemblies 2.Interior metal spring leaf 34 is installed in walking in the groove of torsion lid outer ring 22 with outer metal spring leaf 35.Copper band 32 in one end of interior metal spring leaf 34 connects, the other end connect the negative pole of LED lamp driver plate 31; One end of outer metal spring leaf 35 connects outer copper band 33, and the other end connects the positive pole of LED lamp driver plate 31.Interior elastic contact chip 36 1 ends that are installed in the instrument casing 1 are connected to tool switch 11 power supply cathode contacts by lead, and the other end is resisted against on the periphery of interior copper band 32; Outer elastic contact chip 37 1 ends are connected to tool switch 11 power supply cathode contacts by lead, and the other end is against the end face of outer copper band 33.Because of the elastic reaction of elastic contact chip, guarantee that they keep in touch state with interior copper band 32 and outer copper band 33 all the time.So, under normal circumstances, connect all the time to power supply power switch whole piece circuit from LED lamp 38, by the break-make of tool switch, guarantee the power supply of LED lamp 38, i.e. normal break-make.
In the electric tool that originally has rotatable many lamps light structures, when it need export different moments and the rotary torsion output device---during torsion cap assemblies 2, torsion cap assemblies 2 because with the LED lamp driver plate 31 of light fixture 3, interior copper band 32, outer copper band 33, interior metal spring leaf 34, outer metal spring leaf 35 is relatively-stationary, so rotate together, and interior elastic contact chip 36 and outer elastic contact chip 37 are because being fixed in the instrument casing 1, so slide on their each comfortable interior copper bands 32 and the outer copper band 33, because the elastic reaction of interior elastic contact chip 36 and outer elastic contact chip 37 self, torsion cap assemblies 2 rotates to arbitrary position, remain between interior elastic contact chip 36 and outer elastic contact chip 37 and interior copper band 32 and the outer copper band 33 and contact, and polarity remains constant, thereby guarantees the operate as normal of LED lamp 38.
As can be seen from the figure, there is no directly between the tool switch 11 on torsion cap assemblies 2 and the instrument casing 1 of rotation and be connected with lead, but with being slidingly connected between elastic contact chip and the copper band, so not only can realize 360 ° of rotations of torsion cap assemblies 2, nor can produce the generation of the situations such as lead winding, fracture even short circuit in the similar conductor connecting structure.
In the present embodiment, the quantity of LED lamp 38 is traditionally arranged to be 3～9, to guarantee the effect of floor light.
In sum, the electric tool with rotatable many lamps light structures of the present invention, simple in structure, easy to use, the reliability height is not limited by or not the space, low cost of manufacture, good illumination effect.
Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that this only illustrates, protection scope of the present invention is limited by appended claims.Those skilled in the art can make numerous variations or modification to these embodiments under the prerequisite that does not deviate from principle of the present invention and essence, but these changes and modification all fall into protection scope of the present invention.
