2. Description of Related Art
A floodlight is a necessary commodity in daily life. Along with an increasing living standard, commodities are highly requested by people continuously. Such a type of floodlight cannot be replaced for a demand. Thus, features of high illumination, long operation time, and low weight are required for use. Along with a progressive technology, the existing product is continuously improved in appearance and inner structure and manufactured for various types. However, the product's shape and comfort index is less considered; for example, most of the floodlights are carried with one hand to illuminate and thus limited in use in some occasions.
A headlamp disclosed in patent No. 200420003520.X is structured with a lamp body, a head wrap, and a lamp receptacle and designed for the lamp body of which two sides are formed straps for a human head. The lamp receptacle is connected to the lamp body through a rotation part, freely revolves through a revolving handle grip, locates the rotation part. The headlamp has some defects: 1. arrangement of the head receptacle separate from the lamp body so that a lead wire is used to connect the two parts, in which the lead wire is exposed and thus is easily split; 2. fixing of the lamp receptacle to the head strap, being limited in occasions in use; 3. immediate battery charging or dry battery replacement being required, when the power runs out, because the lamp illuminates with a charging or dry battery, thereby the headlamp failing to normally illuminate in the limited conditions.
Consequently, because of the technical defects of described above, the applicant keeps on carving unflaggingly through wholehearted experience and research to develop the present invention, which can effectively improve the defects described above.
In this invention, a floodlight that may be easily taken from head is provided and serves as a headlamp that is charged by swaying with one hand and may be dismantled.
For achievement of the object, in a skill of this invention, the headlamp that may be dismantled comprises a fixture with a head strap, and a floodlight. The floodlight comprises a lamp body and a lamp receptacle, being characterized in that the head body and lamp receptacle of the floodlight is an all-in-one unit and the floodlight and the fixture mount may be dismantled from each other or inserted to match with each other. In the manner, the floodlight may be taken apart from the fixture mount to serve as an ordinary flashlight for an extra use of the headlamp.
For a further arrangement of this invention, a mounting plate is connected with a turning joint to the fixture mount and the floodlight may be dismantled and then inserted onto the mounting plate. The turning joint is on the fixture mount in an L shape. A guidance groove is formed at each of two sides of downsides of the mounting plate. A lead rail is formed on the lamp body of the corresponding floodlight that is inserted to match with the two sides of downsides. A shift limit lug is provided at a top of the downside of the mounting plate. A shift limit hole is formed in a position where the shift limit lug is corresponding to the lamp body for insertion and matching.

A shaft of the rocking handle is arranged near a side of the lamp receptacle of the housing. A receiving hole for a handle portion of the rocking handle is formed at an end tip near the downside of housing, and when the rocking handle is not used, the handle portion of rocking handle is set into the receiving hole. Thus, an electric power of the floodlight may be generated in conditions of no battery and AC power supply, and the floodlight is not limited to other conditions, thereby being adapt to outdoor illumination.
For a further arrangement of this invention, lead grooves are provided at the two sides of an end of handle portion of the rocking handle and at the two sides of the downside of mounting plate for insertion and matching. The shift limit lug of which a cross section is in a T shape is provided at the top of downside of the mounting plate, and the shift limit hole correspondingly wedged to match with the shift limit lug is provided on the rocking handle to prevent the floodlight from falling transversally. The shift limit hole comprises a center hole and an adjacent hole. The center hole is divided into a big-aperture port and a small-aperture port, the inner side of big-aperture port communicates that of the small-aperture port through their corresponding curved faces. The adjacent hole is formed outside of the two curved faces. The shift limit lug is placed from the big-aperture port of center hole and glides to the small-aperture port to transversally and longitudinally wedge to and match with the shift limit hole, which is a scientific way of achievement of simple manufacturing, material saving, higher fastness after installation; indeed, another manner may be applied; for example, the shift limit hole is just a hole, a material made into the part is certainly flexible, so it is not a bit affected.
For a next arrangement of this invention, two insertion bars are correspondingly provided at the side of mounting plate. A distance between the two insertion bars is equal to a duration of the handle portion of rocking handle. An insertion slot is formed in the accommodation hole for the handle portion of rocking handle at the end tip near the downside of the housing of lamp body.
