Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the desk lamp to the scalable adjusting of the present invention is described in further detail:
As shown in Fig. 1,7, the desk lamp of scalable adjusting of the present invention, comprises lamp socket 1, illuminating lamp 2.As shown in Fig. 1,2, lamp socket 1 is large semi-spherical shape, and its top is seat surface 20, and its underpart is base 21, and seat surface 20 can rotate on base 21.In lamp socket 1, be provided with the winding roll 3 that can rotate around axis, on winding roll 3, be wound with two winding 4, winding 4 is conductor, there is certain thickness and elasticity, and the weight of illuminating lamp 2 is limited, enough illuminating lamp 2 can be supportted aloft, play the effect of support bar, but there is good toughness, only can bend and can not be fractureed if be subject to the effect of extraneous stubborn power.
Winding 4 tail ends are connected with power line, and power line accesses in seat surface 20 from base 21, and winding 4 head ends are connected with the electrode of illuminating lamp 2.Utilize winding 4 as wire, power supply is conducted to illuminating lamp 2 from power line.Winding 4 surfaces are coated with a layer insulating, as insulated paint, cause short circuit phenomenon to prevent electric shock or winding 4 from contacting with winding 4.Winding roll 3 in lamp socket 1 has two, parallel being set in parallel of axis of two winding rolls 3.In the present embodiment, to adopt LED lamp be light emitting diode to illuminating lamp 2, and its operating current is little, and operating voltage is low, and the winding 4 that scribbles insulated paint is enough to reach withstand voltage standard.
A winding roll 3 can be set as required, and not shown, two winding 4 can be wound on a winding roll 3, in the time of winding roll 3 forward and backward, when two winding 4 are drawn simultaneously, when contracting, produce rotation thereupon.Also can arrange as required two with winding roll 3, on each winding roll 3, be wound with a winding 4.
As shown in Figure 4, be provided with wind spring 9 in lamp socket 1, wind spring 9 is for the steel coil strip with favorable elasticity is around forming.Wind spring 9 two ends are separately fixed on winding roll 3 and lamp socket 1, and wind spring 9 is arranged in the time that winding roll 3 is drawn rotation by winding 4, and wind spring 9 is in being rolled tightly state.Now, once winding 4 loses pulling force, wind spring 9 will open, and drive winding roll 3 to turn round, and winding 4 is reeled, and winding 4 is bounced back, and wind spring 9 progresses into relaxed state, has automatic packing up function.
Winding roll 3 is provided with axis hole 6, and wind spring 9 is wound in axis hole 6, and lamp socket 1 is provided with two back shafts 7.Two winding rolls 3 are separately fixed on two back shafts 7 in lamp socket 1 by axis hole 6 separately, and winding roll 3 can rotate around back shaft 7.
Wind spring 9 is wound on back shaft 7, on back shaft 7 and axis hole 6 inner sides, is equipped with draw-in groove, and the two ends of wind spring 9 are separately fixed on the draw-in groove of axis hole 6 inner sides and back shaft 7, and wind spring 9 is arranged in the time that winding roll 3 is drawn rotation by winding 4, and wind spring 9 is in being rolled tightly state.Now, once winding 4 loses pulling force, wind spring 9 will open, and drive winding roll 3 to turn round around back shaft 7, and winding 4 is reeled, and winding 4 is bounced back, and wind spring 9 progresses into relaxed state, has automatic packing up function.
Winding roll 3 is provided with pitch wheel 8, thereby ensure that two winding rolls 3 can synchronously rotate, as long as any one winding 4 is pulled outwardly and pulls, 4 of another winding can keep synchronously being taken out of, backrush is also the same, has avoided two winding 4 to pull out the inconsistent phenomenon of length and has occurred.
Winding 4 is tilting, and its side is perpendicular to horizontal plane setting.Because the gravity of illuminating lamp is pressed in downwards in winding 4, the side of winding 4 is perpendicular to horizontal plane setting can prevent that winding 4 from bending, and also has a good support force even if winding 4 is thin.
The curved structure of winding 4 cross section.Because arc winding 4 is different to the buckling strength of two face directions, therefore two arc winding 4 are symmetrical arranged, can increase the bend resistance intensity of winding 4 to both sides, wave the both sides that can greatly reduce arc winding 4, has strengthened the rigid support intensity of winding 4.
In lamp socket 1, be provided with the card key 10 of suppressing on winding roll 3.In the time that suppressing of card key 10 acts on resistance on winding roll 3 and is greater than the backrush power of wind spring 9, can prevent that winding roll 3 from rotating, make winding 4 keep being supported on certain height.Unclamp card key 10, winding roll 3 can be by winding 4 backrush under the effect of wind spring 9 backrush power, and the length that can regulate winding 4 to stretch, plays the effect of automatic adjusting.
Winding roll 3 one sides are provided with ratchet 11, and card key 10 is suppressed on the ratchet of ratchet 11, and lamp socket 1 is provided with the button 12 linking with card key 10.After button 12 is pressed, can drive card key 10 to move, make card key 10 jack-up leave ratchet, now winding roll 3, in rotary state, can drive card key 10 to move after button 12 is upspring, and card key 10 is stuck on ratchet, and now winding roll 3 is in blocking state.Therefore can, by pulling winding 4 to adjust the height that illuminating lamp 2 rises, then adjust by pressing keys 12 height that illuminating lamp falls for 2 times, and be locked on the height of setting.
As shown in Fig. 2,3, be provided with a casing 5 at lamp socket 1, winding roll 3, winding 4, back shaft 7, wind spring 9, card key 10 are all arranged in casing 5, easy to assembly.
As shown in Figure 5, winding 4 head ends are provided with end axle 13, and end axle 13 is provided with.End axle 13 can be fixed together two winding 4 on the one hand, makes two winding 4 to be synchronously stretched and to shrink, and on the other hand for lampshade 19 provides an axle, this lampshade 19 can rotate around end axle 13, and illuminating lamp 2 is arranged on lampshade 19.Therefore, illuminating lamp 2 can rotate along with the rotation of lampshade 19, to change irradiating angle.
Lampshade 19 is provided with the conducting strip 14 being electrically connected with illuminating lamp 2, and conducting strip 14 is enclosed within on end axle 13 in the form of a ring, can rotate with lampshade 19 1 winding end axles 13, and winding 4 head ends are provided with the electrical contact 15 that can withstand on conducting strip 14 sides.Power supply reaches electrical contact 15 through winding 4, then reaches illuminating lamp 2 through conducting strip 14, and when lampshade 19 is in the time that end axle 13 rotates, 15 of electrical contacts keep in touch slip on the ring side of conducting strip 14, keep "on" position always, realize flexible lamp and connect.
Because winding 4 is arcuate structure; therefore be provided with intermediate plate 16 in each winding 4 both sides; two intermediate plates 16 add the both sides that are held in winding 4; arc winding 4 is fixed and can produce distortion on the one hand; two intermediate plates 16 can strengthen the rigidity intensity of winding 4 head ends on the other hand; be equivalent to increase the thickness of winding 4 head ends, made being flexibly connected between winding 4 and lampshade 19 and illuminating lamp 2 have a high intensity, the winding 4 that can avoid lampshade 19 to cause in the winding 4 frequent activities in end is out of shape.
End axle 13 includes nail axle 17 and the screw 18 with screw, after screw 18 screws in the screw of following closely axle 17, just intermediate plate 16, winding 4, lampshade 19 can be fixed together.
The desk lamp of the scalable adjusting of the present invention has the following advantages with respect to the desk lamp tool of prior art:
Lightness sensation in the upper and heaviness in the lower, puts steadily.The height of illuminating lamp is easy to adjust, and support portion can be packed up completely, takes up space little, is convenient for carrying, and deposits.When use, support portion can be launched again completely, makes the height adjustable range maximum of illuminating lamp.
