Abstract
An electrical flashlight comprises a barrel body, a luminous body and a light gathering element, wherein the barrel body is provided with a power supply placing cavity, and the luminous body and the light gathering element are connected on the barrel body. The electrical flashlight is characterized in that a leading element and a sliding element which can move along the axial direction of the barrel body on the leading element are arranged on the barrel body, the light gathering element is installed on the sliding element, relative displacement of the light gathering element and the luminous body along the axial direction of the barrel body can be realized along the movement of the sliding element, and when the sliding element moves to enable the luminous body to leave the light gathering element, and the sliding element can undraw a luminous body light transmitting zone in the radial zone corresponding to the luminous body position. The electrical flashlight utilizes the movement of the sliding element to realize corresponding displacement of the light gathering element and the luminous body along the axial direction of the barrel body, can realize the focusing function, also can undraw the luminous body light transmitting zone in the radial zone corresponding to the luminous body position for enabling light beams of the electrical flashlight to be transferred from the projection long the axial direction of the barrel body to the projection along the radial direction of the barrel body, the lighting zone of the electrical flashlight can be changed, and the uses can be wider.
Description
Technical field:
The utility model relates to a kind of lighting device, is a kind of torch specifically.
Background technology:
Existing torch has multiple structure, more traditional structure is a kind of flashlight made from metal material that comprises lamp holder, cylindrical shell, tail-hood, lamp holder is provided with reflector as collective optics, battery is installed in cylindrical shell, the front end of cylindrical shell is installed bulb, lamp holder directly is connected on the cylindrical shell and with bulb by screw thread and covers, and during focusing, directly the reflector of rotary lamp holder change lamp holder and the relative position of bulb are realized.
Yet, find in the use that existing torch is owing to form directed light beam, its field of illumination is limited to, and illumination functions is limited to.
Summary of the invention:
A kind of torch of providing the field of illumination variable is provided the purpose of this utility model.
A kind of torch, comprise cylindrical shell, illuminator and collective optics, described cylindrical shell has power supply and lays the chamber, and this illuminator and collective optics are connected on the cylindrical shell, it is characterized in that: cylindrical shell is provided with leading element and one can be at the axially movable element that slides of leading element upper edge cylindrical shell, described collective optics is installed in and slides on the element, do along drum shaft to relative displacement with the mobile realization collective optics and the illuminator that slide element, and, slide the radial zone of element and draw back an illuminator light transmission area in the corresponding illuminator of cylindrical shell position when sliding element operation when causing illuminator to leave collective optics.
Above-mentioned a kind of torch is characterized in that: when sliding element operation when causing illuminator to leave collective optics, described leading element is exposed,
Improvement as such scheme is characterized in that: described leading element is positioned at illuminator periphery and printing opacity, is the tubular design, forms described illuminator light transmission area; The described element that slides also is the tubular design, is enclosed within on the leading element.
Above-mentioned slide element operation and finish cause illuminator to enter the collective optics stroke after, slide element and will draw back an illuminator light transmission area sealing at the radial zone of the corresponding illuminator of cylindrical shell position.
Improvement as such scheme is characterized in that: described leading element with slide the element threaded engagement.
Improvement as such scheme is characterized in that: described leading element is being provided with friction non slip surface or tread plate with the mating surface that slides element.
Improvement as such scheme is characterized in that: slide element and be provided with friction non slip surface or tread plate at the mating surface with the leading element.
Above-mentioned collective optics is a reflector.
Advantage of the present utility model is: the utility model utilization is slided the mobile realization collective optics and the illuminator of element and is done along drum shaft to relative displacement, this process not only can realize the function of focusing, can also draw back an illuminator light transmission area at the radial zone of the corresponding illuminator of cylindrical shell position, make the torch light beam from along drum shaft to project along cylindrical shell projection conversion radially, the field of illumination of torch is changed, and it is more extensive that purposes becomes.When the torch light beam of torch during along radially projection of cylindrical shell, torch can vertically be placed, and uses as general lighting.
