Description

AREA OF THE UTILITY MODEL

[0001] The present utility model falls within the technical field of lighting devices and specifically concerns a desk lamp. STATE OF THE ART

[0002] A standard desk lamp generally consists of a lamp head, a lamp base, and a lamp rod mounted between the lamp head and the lamp base. During use, the lamp base is placed by the user on a table, the floor, or similar surface.

[0003] Existing desk lamps can be divided into desk lamps with multiple lamp rods and desk lamps with a single lamp rod.

[0004] Desk lamps with multiple lamp rods consist of at least two lamp rods that are connected to each other in a rotatable manner. The lamp rod closest to the lamp head is connected to the lamp head in a rotatable manner.

[0092] As in Fig. 13, in some embodiments of the present utility model, the fastening component 340 has a pressure groove 3401 on the side facing the lampshade 310, which corresponds to the locking groove 3102. The rotary component 330 is inserted into the locking groove 3102 and the pressure groove 3401, so that the rotary component 330 is rotatably mounted in the lampshade 310.

[0093] Furthermore, a snap arm 341 is arranged on the side of the fastening component 340 facing the lampshade 310, wherein the pressure groove 3401 is formed on the side of this snap arm 341 facing the lampshade 310. In addition, this snap arm 341 can interfere with the segment of the rotating body 331 between the two annular grooves 3311 (as in Fig. 9 and Fig. 18 shown).

[0094] As continued in Fig. 13, the fastening component 340 has a horizontal through-hole 3402 which corresponds to the horizontal threaded hole 312 in the lampshade 310, so that the cross bolt 382 is passed through the horizontal through-hole 3402 and screwed to the horizontal threaded hole 312 in order to fix the fastening component 340 to the lampshade 310.

[0095] It will continue on Fig. 13. In some embodiments of the utility model, the fastening component 340 is further provided with a plug-in connection hole 3403, while the intermediate disc 350 is provided with a plug-in block 351. This plug-in block 351 is inserted into the fastening component 340 and thus connects the intermediate disc 350 to the fastening component 340.

[0096] Preferably, both the plug connection hole 3403 and the plug block 351 are non-circular in order to prevent rotation of the intermediate disk 350 relative to the fastening component 340.

[0097] In addition, a cable passage 3511 is provided in the plug-in block 351 through which the cables originating from the rotating body 331 can be guided.

[0098] As continued in Fig. 13, the fastening component 340 in some embodiments of the present utility model has on its side facing the lampshade 310 a limiting projection 342 which is embedded in the limiting groove 3312 (see Fig. 17 and Fig. 18).

[0099] During the rotation of the desk lamp 001, the rotating member 330 cannot rotate due to its plug connection with the lamp rod 200. However, the fixing member 340 rotates, causing the limiting projection 342 to move in the limiting groove 3312. When the limiting projection 342 moves to one end of the limiting groove 3312 in the longitudinal direction, the lamp head 300 cannot rotate any further.

[0100] As in Fig. 5, Fig. 6, Fig. 14 and Fig. 15, the side housing 361 is provided with a first through hole 3611 corresponding to the first horizontal threaded bushing 313 on the lampshade 310, so that the first bolt 383 is passed through the first through hole 3611 and screwed to the first horizontal threaded bushing 313 to fix the side housing 361 to the lampshade 310.

[0101] As in Fig. 14 and Fig. 15, a second horizontal threaded column 3612 is arranged on the side of the side housing 361 facing the lampshade 310, while the fixing plate 365 is provided with a second through hole 3651, so that the second bolt 384 is passed through the second through hole 3651 and screwed to the second horizontal threaded column 3612 to fix the fixing plate 365 to the side housing 361.

[0102] Furthermore, the mounting plate 365 is provided with a bolt through hole 3652 which avoids the first bolt 383.

[0103] Additionally, the mounting plate 365 is positioned on the underside of the circuit board 364 and connected to the circuit board 364. Thus, the circuit board 364 is fixed to the side housing 361 via the mounting plate 365. The connection between the mounting plate 365 and the circuit board 364 can be realized by welding, gluing, snap-in connection, or other suitable methods.

[0104] As in Fig. 5, Fig. 14, Fig. 15 and Fig. As shown in Figure 17, the control knob 362 is disposed on the top of the side housing 361, while the decorative cover 370 has an escape hole 3702 for the control knob 362. This allows the control knob 362 to pass through the recessed hole 3702 or to be partially positioned in the escape hole 3702.

[0105] An assembly process of the lamp head 300 in some embodiments of the present utility model will be briefly explained below.

[0106] As in Fig. 14 and Fig. 15, first, the mounting plate 365, the circuit board 364 and the side housing 361 are fastened into a whole by means of the second bolt 384.
