Description

Multi-functional hand-held illumination bars

Technical field

The utility model relates to a kind of hand-held electric lighting, and particularly a kind of is the multi-functional hand-held illumination bars of illuminating source with the light emitting diode.

Background technology

Along with the appearance of high brightness LED, the electric lighting that exploitation is made light source with the light emitting diode of this high brightness, power saving is paid attention to by people.At present, the multi-functional hand-held illumination bars of domestic appearance is exactly a kind of electric lighting.The multi-functional hand-held illumination bars of this class, has a transparent cylinder, cylinder one end has an optically focused head and is enclosed within the outer fixed cover that is threaded with cylinder of optically focused head, a sealing ring is arranged between optically focused head and cylinder end face, the cylinder other end has the barrel-shaped handle that is threaded, seal by the sealing ring between cylinder and the handle, cylinder and handle constitute in the inner chamber a link, on this link circuit board is arranged, battery compartment, charging socket, several high brightness LEDs and a push type change-over switch are housed on the circuit board,, make the change-over switch conversion by the push-botton operation on the handle, thereby realize optically focused hair light, illuminate distant object, the road surface, or circuit board top luminous tube is luminous, illumination nearby, or all luminous tube is luminous on the circuit board, improves brightness of illumination.Also have a jack corresponding on the handle,, realize the battery charge in the battery compartment with being electrically connected of the charging socket on the output plug that makes things convenient for charger and the link with charging socket.

Yet the multi-functional hand-held illumination bars of this class because the button on its handle adopts conventional structure, exists cylinder bore and the extraneous gap of linking up.In the jack on the simultaneously corresponding handle wall dust plug is only arranged with charging socket, run into the rainy day use, or fall into because of carelessness in the puddle, water or steam very easily enter the inner chamber of illumination bars by above-mentioned gap, cause inner element leakage, corrosion, battery discharge, even control malfunctioning.

The utility model content

At above-mentioned existing in prior technology problem, the purpose of this utility model provides that a kind of water resistance is good, the multi-functional hand-held illumination bars of reliable operation.

Technical solution of the present utility model is: a kind of multi-functional hand-held illumination bars, has a transparent cylinder, cylinder one end has an optically focused head and is enclosed within a fixed cover that is threaded with cylinder on the optically focused head, a sealing ring that between optically focused head and cylinder, has and optically focused head front window rear surface and cylinder end face closely to contact, the cylinder other end has a barrel-shaped handle that is threaded, and a compacted sealing ring is arranged between the screw thread seam face of this handle and the cylinder end face; In the inner chamber that cylinder and handle constitute a link is arranged, the circuit board that is roughly parallel to cylinder axis is arranged on the link, battery compartment, charging socket, described circuit board comprises several high brightness LEDs and a push type change-over switch, on the described handle with circuit board on push type change-over switch corresponding position a button is arranged, this button has a guide hole and the seat hole coaxial with guide hole on the handle wall, a push rod that can contact with the push type change-over switch is arranged in the guide hole, the spring that its both ends of the surface of overcoat contact with shaft shoulder face on bottom surface, seat hole and the push rod respectively on the push rod, the shaft shoulder portion overcoat of described push rod has gentle/flexible sealing cap, be pressed with a pressing plate on the brim of a hat of sealing cap, make the brim of a hat face closely contact and seal with seat aperture side face; On the described handle wall with link on the charging socket corresponding position jack is arranged, there is the device of a salable jack at this jack place.

Described salable jack devices has a cover plate that is rotationally connected with handle wall, between cover plate and jack, be connected on the cover plate with described jack tight-lipped connect airtight to touch have gentle/flexible seal, have away from the position of turning cylinder at described cover plate and to bend to the clamp of its cross section for " U " shape structure, the free margins lateral surface center of clamp is connected with a sawtooth projection, there is a snap close this sawtooth projection corresponding position with clamp on the handle wall, the sty of the sawtooth projection on the described clamp contacts with the snap close face, thereby makes jack keep sealing state.When the free margins of stirring clamp dwindled the opening size of its U-shaped structure, the disengaging of the sty of the sawtooth projection on the clamp contacted with the snap close face, and the cover plate release is opened, and jack exposes.

After adopting said structure, because one in push rod shaft shoulder overcoat on the button has gentle/flexible sealing cap, be pressed with a tight pressing plate that contacts of seat aperture side face that makes on the brim of a hat face and the handle on the brim of a hat of sealing cap, the inner chamber of illumination bars is isolated from the outside, good sealing effect, reliable operation.Owing to be provided with a salable jack devices at the jack place of handle, good seal not only, and the battery charge in the illumination bars is connected also convenient especially.
