1. Field of the Invention
The present invention relates to a flashlight, and more particularly to a flashlight with a telescopic head.
2. Description of Related Art
A conventional flashlight generally includes a cylindrical tube serving as a handle for the conventional flashlight. Two or more dry cell batteries are received in the cylindrical tube for providing electrical energy. An electrical circuit is established from one electrode of the battery through a conductor to a switch, then through a conductor to one electrode of a lamp bulb mounted in a front end of the cylindrical tube. The electrical circuit emerges through a second electrode of the lamp bulb to electrically contact with a conductor for conducting with the other electrode of the battery.
However, the conventional flashlight only provides an illumining effect. When an object, e.g. a sleeve, a screw or a nut, falls in a slit or in a dark nook, the dark nook might be lighted by the conventional flashlight. Therefore, the object still may not be attached. Furthermore, the slit of the dark nook is deeper than a lighting range of the conventional flashlight, the object falling in the slit is hard to be attached.
The present invention has arisen to mitigate and/or obviate the disadvantages of the conventional flashlight.
The main objective of the present invention is to provide an improved flashlight with a telescopic head for providing a telescopic rod having a magnetic head for telescopically magnetizing a screw.
To achieve the objective, the flashlight with a telescopic head in accordance with the present invention comprises a handle having a hollow structure for adapting to receive at least one battery. A switch is laterally disposed on the handle. The handle has a head mounted on one end thereof. The head has multiple lamps mounted therein and a transparent cover mounted thereon. A bouncing mechanism is mounted into the head and has an outer sleeve mounted therein. The outer sleeve has multiple guiders equally formed on an inner periphery thereof and multiple grooves defined therein. Each groove is formed between two adjacent guiders. Each guider has a slantwise bottom formed thereon and a slantwise shoulder notched in the slantwise bottom. The bouncing mechanism has a cam body coaxially and movably received in the outer sleeve. The cam body has multiple first flanges formed on an outer periphery thereof and corresponding to the multiple grooves for slidably moving in the outer sleeve along the multiple grooves. The cam body has a series of teeth formed on a bottom thereof. The bouncing mechanism has a rotatory cam coaxially and selectively received in the outer sleeve. The rotatory cam has multiple second flanges formed on an outer periphery thereof for corresponding to the multiple grooves. Each second flange has a top complementally corresponding to the slantwise shoulder of the guider for engaging to the slantwise shoulder. The rotatory cam has a series of second teeth formed on a top thereof. The bouncing mechanism has a spring disposed in the handle for connecting to a bottom of the rotatory cam and an interior of the handle. A telescopic rod is received in the head and the bouncing mechanism and has a head member disposed on one end thereof. The head member is abutted against a top of the cam body and has a magnetic head mounted thereon for adapting to magnetize a screw.
The multiple second flanges are respectively engaged to a corresponding one shoulder of the multiple guiders. The head member is downwardly pressed and abutted against the top of the cam body receiving in the outer sleeve. The series of first teeth of the cam body is downwardly and slantwise engaged with the second teeth of the rotatory cam to rotate the rotatory cam for detaching the multiple second flanges from the corresponding shoulder such that the rotatory cam is received in the outer sleeve and abutted against the cam body due to a restitution force of the spring for protruding the head member from the head.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
Referring to the drawings and initially to
The handle (1) has a hollow structure. At least one battery (20) is received in the handle (1) from the second end of the handle (1). A cap (111) is detachably mounted on the second end of the handle (1). A switch (12) is disposed on an outer periphery of the handle (1) and electrically contacts with the head (10) and the at least one battery (20) for selectively turning on/off the flashlight. The head (10) has multiple lamps (104) mounted therein and a transparent cover (105) mounted thereon such that light projected from the multiple lamps (104) passes through over the transparent cover (105). In the preferred embodiment of the present invention, the multiple lamps (104) are LEDs (Lighting Emitting Diode).The transparent cover (105) has a hole (1051) centrally defined therein for receiving a telescopic rod (101).
The bouncing mechanism (13) has an outer sleeve (131) mounted therein. The outer sleeve (131) has multiple guiders (1314) formed on an inner periphery thereof. Between each two adjacent guiders (1314) has a groove (1311) defined therein to form multiple grooves (1311). Each guider (1314) has a slantwise bottom (1313) formed thereon and a slantwise shoulder (1312) notched in the slantwise bottom (1313). The bouncing mechanism (13) has a cam body (1321) coaxially and slidably received in the outer sleeve (131). The cam body (1321) has multiple first flanges (13212) formed on an outer periphery thereof and corresponding to the multiple grooves (1311) for slidably moving in the outer sleeve (131) along the multiple grooves (1311). The cam body (1321) has a series of first teeth (13211) formed on a bottom thereof. The bouncing mechanism (13) has a rotatory cam (1322) coaxially and selectively received in the outer sleeve (131). The rotatory cam (1322) has multiple second flanges (13222) formed on an outer periphery thereof for slidably moving in the outer sleeve (131) along the multiple grooves (1311). A top of each second flange (13222) has a shape complementally corresponding to a shape of the slantwise shoulder (1312) of the guider (1314) of the outer sleeve (131) for engaging to the slantwise shoulder (1312). The rotatory cam (1322) has a series of second teeth (13221) formed on a top thereof. The bouncing mechanism (13) has a spring (133) connecting to a bottom of the rotatory cam (1322) and the spring (133) is compressively received in the handle (1).
The telescopic rod (101) is received in the hole (1051) in the transparent cover (105) of the head (10) and has one end connected to an interior of the handle (1) via the cam body (1321) and the rotatory cam (1322). The telescopic rod (101) has a head member (not numbered) disposed on the end thereof. An adjusting portion (1011) is disposed between the telescopic rod (101) and the head member and is bendable such that the head member is freely pivotable. The head member is abutted against a top of the cam body (1321). The head member has a lamp portion (102) disposed thereon and a magnetic head (103) disposed on the lamp portion (102) to illuminate in a slit and magnetize a screw. In the preferred embodiment of the present invention, the lamp portion (102) is a LED (Lighting Emitting Diode).
