Description
Technical field
The present invention relates to desk lamp magnifier technical field, be specially a kind of portable desk lamp magnifier.
Background technology
Magnifier is used to observe the simple visual optical device of object detail, is the much smaller collecting lens of the distance of distinct vision of focal distance ratio eye.Object size of imaging on human eye retina is proportional to the angle (visual angle) that eye is opened by thing.Visual angle is bigger, as also bigger, more can differentiate the details of thing.Shift near object and can increase visual angle, but be subject to the restriction of eyes focusing ability.Use magnifier, make it against eyes, and within thing being placed on its focus, become a upright virtual image.The effect of magnifier is to amplify visual angle.
Existing desk lamp magnifier, in order to be convenient for carrying, is all that employing is folding.Mainly including hinged successively base, Collapsible rack and installing frame, enlarging lens is embedded in installing frame, and what be provided with after folding that one piece of installing frame of magnifier is overlapped is arranged on topmost.But going to see some things sometimes for hand-held magnifier, at this moment, this desk lamp magnifier just seems very inconvenient, and, the existing general brightness of desk lamp magnifier is fixing, it is impossible to regulate brightness.
Summary of the invention
Present invention aims to above-mentioned the deficiencies in the prior art, it is provided that a kind of portable desk lamp magnifier.
The technical scheme is that and be achieved in that: a kind of portable desk lamp magnifier, including base, first support, second support and amplification picture frame, described first support one end is hinged with base, described base and amplification picture frame are all circular ring structure, described second support one end is hinged with the first support other end, the described second support other end is hinged with amplification picture frame, described second support can fold in the first support, it is installed with magnifier in described amplification picture frame, described amplification picture frame is provided with LED bulb, described second support is provided with on and off switch, described second internal stent is provided with battery, described battery is that LED bulb is powered.
Preferably, described base is provided with the groove corresponding with described amplification picture frame.
Preferably, described on and off switch adopts single-pole double-throw switch (SPDT), including common port, the first gating branch road and the second gating branch road.
Preferably, described LED bulb has 10, its negative pole is all electrical connected with battery cathode, described on and off switch common port and anode are electrical connected, described first gating branch road is electrical connected by the positive pole of diode with 5 in described 10 LED bulb, and the positive pole of described 10 LED bulb is electrical connected each through diode and the second gating branch road.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is easy to use, simple in construction, easy to carry, table magnifier can be regarded and use, it is also possible to use as hand magnifier, be also equipped with two kinds of brightness of illuminations.

Fig. 3 is LED bulb power supply circuit.
In figure: 1, base, 11, groove, the 2, first support, the 3, second support, 31, on and off switch, 32, battery, 4, amplify picture frame, 41, LED bulb, 5, magnifier.
Detailed description of the invention
Refer to Fig. 1-3, the present invention provides a kind of technical scheme: a kind of portable desk lamp magnifier, including base 1, first support 2, second support 3 and amplification picture frame 4, described base 1 and amplification picture frame 4 are all circular ring structure, described first support 2 one end is hinged with base 1, described second support 3 one end is hinged with first support 2 other end, described second support 3 other end is hinged with amplification picture frame 4, described second support 3 can fold in the first support 2, it is installed with magnifier 5 in described amplification picture frame 4, described amplification picture frame 4 is provided with LED bulb 41, described second support 3 is provided with on and off switch 31, described second support 3 is internally installed battery 32, described battery 32 is powered for LED bulb 41.Described base 1 is provided with the groove 11 corresponding with described amplification picture frame 4, when the second support 3 is folded in the first support 2, amplifies picture frame 4 and can buckle in base 1.Described on and off switch 31 adopts single-pole double-throw switch (SPDT), including common port, the first gating branch road and the second gating branch road.Described LED bulb 41 has 10, its negative pole is all electrical connected with battery 32 negative pole, described on and off switch 31 common port and battery 32 positive pole are electrical connected, described first gating branch road is electrical connected by the positive pole of diode with 5 in described 10 LED bulb 41, and the positive pole of described 10 LED bulb 41 is electrical connected each through diode and the second gating branch road.
Need further illustrate be, this portable desk lamp magnifier has two kinds of forms, both can regard table magnifier to use, hand magnifier can also be regarded use, when by first support the 2, second support 3 and amplification picture frame 4 all expansions, table magnifier being regarded and use, when the second support 3 is folded in the first support 2, when amplification picture frame 4 buckles in base 1, the first support 2 and the second support 3 use as handle, now use as hand magnifier.
Embodiment provided above is the better embodiment of the present invention, only it is used for the present invention is conveniently described, not the present invention is done any pro forma restriction, any art has usually intellectual, if in the scope without departing from the carried technical characteristic of the present invention, utilize disclosed technology contents to be made the Equivalent embodiments that local is changed or modified, and without departing from the technical characteristic content of the present invention, all still fall within the scope of the technology of the present invention feature.
