Description
Technical field
The utility model relates to a kind of head lamp, specifically a kind ofly can conveniently adjust brightness and range of exposures, and head lamp easy to use.
Background technology
People such as mountain-climbing, encamp or catch fish and shrimp etc., do other activity in order to vacate both hands when carrying out night outdoor leisure activity, all can dress a head lamp at head usually, and it is a kind of more satisfactory illuminations that uses.Existing head lamp kind is many, and the most frequently used is the head lamp that adopts light emitting diode, and this head lamp has long advantage of power saving, brightness height and life-span.But existing brightness and the range of exposures of the head lamp of light emitting diode of adopting can not be adjusted, and running into need concentrate brighter irradiation or spread darker irradiation the time, and this head lamp just can not meet the demands.
The utility model content
The purpose of this utility model provides a kind ofly can conveniently adjust brightness and range of exposures, and head lamp easy to use.
The purpose of this utility model is achieved through the following technical solutions.
A kind of head lamp, comprise headband, support, battery case, stationary pipes and light emitting source, headband is located in the hole on the support, battery case and support articulate, stationary pipes is installed on the battery case, light emitting source is installed in the stationary pipes, it is characterized in that: described stationary pipes wears a sliding tube that can slide outward on stationary pipes, and convex lens are installed in the sliding tube.
The end of described stationary pipes is provided with external screw thread, and a protecgulum is threaded on the stationary pipes, and convex lens are between stationary pipes and protecgulum.
The inwall of described sliding tube is provided with a collar flange, and convex lens are installed in the end of stationary pipes by a pressure ring, and the outer rim of pressure ring is fastened on the annular lip.
Be provided with a waterproof apron between described protecgulum and sliding tube.
The articulated section of described battery case is provided with a positioning block, and the articulated section of support is provided with an alignment pin, and locating piece is connected on the alignment pin.
The utility model compared with prior art has the following advantages.
When head lamp described in the utility model slides on stationary pipes relatively by sliding tube, can change the distance between convex lens and the light emitting source, thereby change brightness and range of exposures, it is very convenient to operate; The waterproof apron that is provided with between protecgulum and sliding tube has good waterproof effect, is suitable for using when weather is not good; The articulated section of battery case and support is provided with alignment pin and the locating piece that is connected together mutually, can reach the purpose at angle of inclination, location, so that adjust the irradiating angle of light emitting source when luminous.

The specific embodiment
Below in conjunction with accompanying drawing the utility model head lamp is described in further detail.
To shown in Figure 5, head lamp described in the utility model mainly is made up of with light emitting source 60 headband 80, support 70, battery case 20, stationary pipes 40, sliding tube 50 as Fig. 1.The periphery of support is provided with several perforation 72, and headband is located in the perforation, and headband is the elastic force elastic cord, is convenient to head lamp is worn on the head.Headband comprises level and vertically disposed headband, and an end of horizontal headband is provided with guiding mechanism 81.One end of vertical headband 82 is located in the perforation of support upper limb, and the other end is provided with guiding mechanism 821.Horizontal headband ring set is on user's head, and vertical headband is crossed on user's the head.The lower edge of support is provided with articulated section 71, and the articulated section is provided with alignment pin 73, and alignment pin is a shell fragment.The inside of battery case is provided with the cavity that is used to place battery 30, and the battery in the cavity is electrically connected with the switch 21 on the battery case, has a through hole 22 on the front panel of battery case.Battery case is provided with a back of the body and covers 23, the bottom of back of the body lid is provided with articulated section 231, and the articulated section is provided with a positioning block 232, and the surface of locating piece is provided with several sawtooth that is used to locate, sawtooth on the locating piece and support alignment pin articulate mutually, reach the purpose at inclination angle, location.Be respectively equipped with a perforation 24 on the two side of battery case, the both sides of back of the body lid correspondence respectively are provided with a fixture block 233, and back of the body lid is inserted in to finish in the perforation to install by fixture block with battery case and is connected.One end of stationary pipes outwards passes from the through hole of battery case front panel, makes stationary pipes expose to battery case, and an end of stationary pipes is fixed on the battery case, and the other end is provided with internal thread 41, outer wall upper ring cap one elastic force ring 42 of stationary pipes.Light emitting source is installed on the internal thread of stationary pipes by a pressure ring 61, and the outer rim of pressure ring is fastened on the collar flange 51 on the inwall of sliding tube, reaches spacing anti-skidding purpose.Light emitting source is electrically connected with battery and switch.The sliding tube ring set is in the outside of stationary pipes, sliding tube slides before and after can doing on stationary pipes, and the inwall of sliding tube is provided with a collar flange 52, and an end of sliding tube is provided with external screw thread 52, external screw thread is threaded with a protecgulum 53, is provided with convex lens 54 between protecgulum and sliding tube.Elastic force ring outside the stationary pipes occurs rocking to reduce sliding tube when sliding in order to increase the contact point between sliding tube and the stationary pipes.Be provided with a waterproof apron 55 between protecgulum and sliding tube, waterproof apron has good waterproof effect, is suitable for using when weather is not good.
People are when using the utility model head lamp, and the user only need spur or promote sliding tube, change the relative position between sliding tube and the stationary pipes.When sliding tube and stationary pipes relative distance were far away, the distance between convex lens and the light emitting source also became far, and at this moment, the effect of generation light focusing makes the brightness lifting and range of exposures diminishes; When sliding tube and stationary pipes relative distance were nearer, the distance between convex lens and the light emitting source also became closely, at this moment, produced the effect of light diffusion, made the brightness attenuating and range of exposures becomes big.The user can make battery case rotate with respect to the articulated section of support by promoting battery case, and the pin that is positioned of the sawtooth on the locating piece blocks, to produce the variation effect of various angles.
