The specific embodiment
To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.
As Fig. 1～shown in Figure 6,1-adapter sleeve, 2-lamp cover, 3-lamp socket, 4-packing ring, 5-wiring board, 6-switch, 7-gear tooth, 8-tooth bar, 9-Connection Block, 10-elastic cord, 11-movable button, 12-lead, 13-battery case, 14-fluorescent tube, 15-omoplate, 16-back-up ring, 17-sleeve pipe, 18-LED lamp, 19-swivel nut, 20-packing ring, 21-optical lens, 22-bolt, 23-fastener, 24-rubber parts, 25-nut.
A kind of far and near light adjustable type head lamp is made of interconnected Connection Block 9, lamp socket 3, battery case 13 and elastic cord 10.Connection Block 9 and battery case 13 all adopt high-quality plastics to make to alleviate product weight and to prevent electric leakage.
Described Connection Block 9 rear ends connect three elastic cords 10, be respectively the side band of parcel head both sides and the heading tape at top, heading tape and wherein be equipped with the movable button 11 of length adjustment on side band, the other end of three elastic cords is connected on the battery case 13 simultaneously, adopt three joint dry cell power supplies in this battery case, on the wiring board 5 of power supply in lead 12 is connected lamp socket 3, be provided with rubber parts 24 at lead access lamp socket place and carry out the water-tight processing, this lead is fixed by the fastener on the elastic cord 10 23; Connection Block 9 front ends are provided with the hinged seat of disjunctor.
Described lamp socket 3 is fixed into one by the forward and backward lid of mutual fastening through screw, the hinged end that bonnet extends back is hinged in the hinged seat of Connection Block 9 through bolt 22 and nut 25, this hinged end outer surface is provided with along semicircle uniform a plurality of gear teeth 7, therefore the corresponding tooth bar 8 that is provided with on hinged seat with gear tooth engagement has had the position and lock function of rotational angle when lamp socket 3 when Connection Block 9 rotates.
The protecgulum bottom side of lamp socket 3 is provided with switch 6, this switch has high light, the low light level and three kinds of functions of flash of light, use these three kinds of functions must push tertiary switch, whenever after pushing switch, lamp socket all can be according to the order of high light, the low light level and flash of light corresponding ejaculation light, after three kinds of light all occurred once, by a switch, light promptly extinguished again.After if light extinguishes again successively push switch will repeat above-mentioned function course.
The protecgulum front side of lamp socket 3 is gluing to be fixed with the cylindrical shape fluorescent tube 14 that high-strength aluminum alloy material is made, this fluorescent tube front end screw joint casing 17, shoulder structure in having in the sleeve pipe, after on the interior shoulder high-power LED lamp 18 and packing ring 4 being installed successively, the swivel nut 19 that is threaded by the sleeve pipe front end screws again, can prevent that becoming flexible and causing damage from use appearring in the LED lamp, on the wiring board 5 of LED lamp 18 in lead 12 is connected lamp socket 3.
The described fluorescent tube 15 outer lamp covers 2 that are provided with, shoulder structure in having in this lamp cover, after on the interior shoulder packing ring 20 and hemispherical optical lens 21 being installed successively, the adapter sleeve 1 that is threaded by lamp cover front end screws again, can prevent that the light quality from use appearring becoming flexible and influencing in optical lens.This optical lens 21 adopts resin material to make, and has dropproof preferably damage performance and good light transmittance energy.Lamp cover 2 can adopt movable set outside fluorescent tube 14 or be threaded in structure outside the fluorescent tube, these two kinds of structures all can make the lamp cover along fluorescent tube move axially flexible or screw thread flexible, LED lamp 18 in the fluorescent tube 14 will change with optical lens 21 distances that lamp overlaps in 2 like this, can form the throw light of instant and near light.For example lamp overlaps 2 when protruding, the light of projection is the distance light of concentrating, and penetration power is strong, can shine farther distance, can or see through under the situation such as vehicle glass at the very low thick fog of visibility, dense smoke and can also illuminate target, be widely used in search, outdoor exercises etc.; During the inside indentation of lamp cover 2, the light of projection be the dipped beam of dispersion, carries out in-plant illumination use, is widely used in occasions such as reading, illumination, police service.Described lamp overlaps 2 rear ends and is provided with omoplate 15, fluorescent tube 14 outer surfaces are provided with back-up ring 16, be mainly used in that to prevent that lamp cover 2 from pulling out distance in the fluorescent tube 14 excessive and break away from and damage, back-up ring also plays and slows down the effect that lamp cover 2 is pulled out speed simultaneously, so lamp is enclosed within can control in the process of pulling out and pulls out distance, carry out the fine setting of instant and near light and regulate, and can effectively set and make eyes watch the long-pending and lamplight brightness of more comfortable face to be illuminated.Correspondingly overlap 2 surfaces at lamp and also be provided with and pull out the corresponding focal length of distance and identify (not shown) and anti-skid design.
The utility model structure is small and exquisite, good looking appearance, durability are good, the distance light projection distance is far away 4～5 times than dipped beam projection distance, can be worn over head by three elastic cords 10 during use, this structure not only has traditional high light, the low light level and three kinds of functions of flash of light, the regulatory function that also has far and near light, made things convenient for consumer's far away, near field to close the use needs, and can freely set face to be illuminated long-pending size and lamplight brightness, it is more comfortable that eyes are watched.
