Embodiment 1

[0030] combine Figure 1 to Figure 3 As shown, a learning desk lamp for assisting in drawing, including a lamp holder 1, a lamp post 2 and a lampshade 3, a circle of grooves 4 (or a circle of protrusions, or other connecting structures) are formed along the outer surface of the lampshade 3, and the concave The bottom of the groove 4 is provided with a light-transmitting port 5, and a movable ring 6 is set on the groove 4. The movable ring 6 is provided with different light-transmitting geometric figures or lines 7, including triangles, quadrilaterals, circles, and ellipses. , pentagon, hexagon, etc., the lampshade 3 is provided with a light bulb 8, and an assembly for installing the light bulb 8 and driving the light bulb 8 to move up and down.

[0031] Wherein, the assembly includes a driving gear 9, a driven gear 10, a guide rail 11, a moving seat 12 and a tooth plate 13; The bulb 8 is installed on the front end side of the front end, the tooth plate 13 is connected to the ...

Embodiment 2

[0039] combine Figure 5 As shown, the structure of embodiment 2 is basically the same as that of embodiment 1, the only difference is that the assembly includes a slide bar 17, a moving seat 18, a bar magnet 19, an electromagnetic coil 20 and an adjustment knob 21; the slide bar 17 is vertically The erection is installed in the lampshade 3, the moving seat 18 is movably sleeved on the slide bar 17, the bulb 8 is installed on the front side of the moving seat 18, the bar magnet 19 is vertically connected to the rear end side of the moving seat 18, and the electromagnetic solenoid 20 is located directly below the bar magnet 19, and the electromagnetic solenoid 20 is connected with a power supply, and the adjusting knob 21 is arranged on the lamp holder 1 for adjusting the current size of the power supply connected to the electromagnetic solenoid 20.

[0040]After the electromagnetic coil 20 is energized, it produces a magnetic field similar to a bar magnet, and the direction of...

Embodiment 3

[0042] combine Image 6 As shown, the structure of embodiment 3 is basically the same as that of embodiment 1, the only difference is: the assembly includes a slide bar 22, a screw mandrel 23, a moving seat 24 and an adjustment knob 25; the slide bar 22 and the screw mandrel 23 are erected vertically side by side In the lampshade 3, the bulb 8 is installed on the front end side of the moving seat 24, and a threaded hole and a cylindrical hole are vertically opened on the moving seat 24, the slide bar 22 passes through the cylindrical hole, and the screw mandrel 23 passes through the threaded hole and forms Threaded connection, the top of the screw mandrel 23 passes through the lampshade 3, and the adjusting knob 25 is connected to the top of the screw mandrel.

[0043] When the height of the bulb 8 needs to be adjusted, the adjustment knob 25 only needs to be rotated to allow the screw mandrel 23 to rotate, so that the moving seat 24 and the bulb 8 can move up and down along t...

Abstract

The invention discloses a learning desk lamp for assisting drawing, which comprises a lamp holder, a lamp pole and a lampshade. A circle of grooves is formed along the outer surface of the lampshade. A movable ring is covered with different light-transmitting geometric figures or lines, and a light bulb is arranged in the lampshade, as well as an assembly for installing the light bulb and driving the light bulb to move up and down. The advantage of the present invention is that the desk lamp for learning can also project different geometric figures on the paper while providing lighting normally, and can directly trace according to the projection when drawing, which improves the drawing efficiency, and the drawing is more accurate and beautiful, and can be Effectively replace a variety of drawing tools; the size of the projected graphics can be adjusted, which cannot be realized by ordinary drawing tools, which greatly improves its practicability; the light source of the appropriate color can be selected according to the color of the projected area to make the projected graphics color The color contrast with the paper surface is larger, and the graphic display is clearer, which is conducive to tracing.

Description

technical field [0001] The invention relates to the technical field of desk lamps, in particular to a learning desk lamp for assisting drawing. Background technique [0002] Primary and middle school students often need to draw geometric figures in the learning process, especially in mathematics courses. In order to make the drawings accurate and beautiful, they need to use various auxiliary drawing tools, such as compasses, rulers and triangular rulers. This has also led to the fact that there are many school supplies for primary and middle school students, which are inconvenient to carry and easy to lose. Frequent repurchases require a lot of money. [0003] Desk lamp is an indispensable article in people's life and study, and every family needs to use it. However, traditional desk lamps can only achieve simple lighting functions and have limitations. To this end, we can study a multi-functional table lamp, which can replace traditional drawing tools by emitting light to...
