Description

Technical Field

[0001] The utility model relates to the technical field of floor lamps, in particular to a floor lamp with a rotatable lamp head. Background Art

[0002] With the improvement of living quality, people have put forward higher requirements for the flexibility and diversity of home lighting. Traditional floor lamps usually consist of a support frame and a lamp head fixed at the top. For example, a floor lamp disclosed in a Chinese patent with the patent application number CN202320030736.8 includes a cover plate, and further includes: a lamp head disposed on one side of the cover plate and fixed to one side of the cover plate; a lamp pole disposed on one side of the cover plate, with one end of the lamp pole connected to the cover plate; and a lamp pole socket disposed on one side of the lamp pole, with the other end of the lamp pole fixedly connected to the lamp pole socket. This floor lamp has the advantages of being placed in areas other than the desk, preventing it from being knocked and causing the floor lamp to fall backward, and the two anti - falling parts can be supported and opened to 90 degrees to prevent the lamp from falling backward. In the above structure, since the lamp head is fixedly connected to the lamp pole, the light can only shine towards the bottom surface, and the light angle cannot be adjusted, making the use not flexible enough, with high limitations and lack of practicality. Summary of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a floor lamp with a rotatable lamp head.

[0023] As Figures 1 to 5 shown, this embodiment discloses a floor lamp with a rotatable lamp head, which includes a lamp base 1, a lamp post 2 fixed on the lamp base 1 and extending vertically upward, a support beam 3 fixed at the top of the lamp post 2 and extending horizontally forward, and a lamp head 4 movably installed at the front end of the support beam 3. The lamp head 4 has a rectangular structure and emits light in a rectangular range to one side. The support beam 3 and the lamp head 4 are connected by a rotating member 5. The rotating member 5 includes a first rotating seat 51, a second rotating seat 52, and a third rotating seat 53. One end of the first rotating seat 51 is fixedly connected to the support beam 3, and the other end is rotatably connected to the top of the second rotating seat 52 through a first rotating shaft 54. The first rotating shaft 54 is arranged in the horizontal direction from left to right; the bottom of the third rotating seat 53 is fixedly connected to the middle of the lamp head 4, and the top of the third rotating seat 53 is rotatably fitted on the second rotating seat 52 to form a second rotating shaft 55. The second rotating shaft 55 is perpendicular to the first rotating shaft 54. When it is necessary to adjust the light angle, the lamp head 4 can be rotated around the first rotating shaft 54 to make the second rotating seat 52 rotate relative to the first rotating seat 51, thereby changing the irradiation angle of the light. The lamp head 4 is rotated around the second rotating shaft 55 to make the third rotating seat 53 rotate relative to the second rotating seat 52, thereby changing the light irradiation range. The two rotating shafts can achieve multi-angle combinations to realize irradiation at various angles, which is more flexible and practical.

[0024] In this embodiment, in order to increase the range of angle adjustment of the lamp head 4, one end of the first rotating seat 51 is inserted into the front end of the support beam 3 and fixed, and the other end extends forward to form a hinge portion. The hinge portion is symmetrically arranged up and down, so that after the second rotating seat 52 is hinged on the hinge portion, it can rotate 180° up and down around the first rotating shaft 54; moreover, the length of the support beam 3 extending forward is greater than the diagonal length of the lamp head 4, avoiding the lamp head 4 hitting the lamp post 2 when rotating around the second rotating shaft 55, so that the lamp head 4 can rotate 360° around the second rotating shaft 55360°.

[0025] In this embodiment, in order to rotatably mate the third rotating seat 53 with the second rotating seat 52, a downwardly opening rotating groove 520 is provided at the bottom of the second rotating seat 52. A limiting block 521 is provided in the rotating groove 520. A through hole is formed in the middle of the third rotating seat 53 to form an annular structure. A limiting groove 530 with a diameter larger than the through hole is further provided on the inner side of the third rotating seat 53. After the third rotating seat 53 with the limiting groove 530 facing downward is placed into the rotating groove 520, the limiting block 521 passes through the through hole and abuts against its limiting groove 530 to limit the third rotating seat 53 in the rotating groove 520. At this time, the limiting block 521 is fixed to the second rotating seat 52 by screws to complete the installation.

[0026] In this embodiment, the lamp head 4 includes an annular rectangular frame body 41, a light emitting panel 42 installed on the front side of the frame body 41, a rear cover plate 43 installed on the rear side of the frame body 41, an LED light strip 44 installed on the rear cover plate 43, and a frame cover 45 fixed to the rear end of the frame body 41. A limiting structure 411 is provided along the edge at the front end of the frame body 41. The light emitting panel 42 is placed from the rear side of the frame body 41 and abuts against the limiting structure 411. A connecting portion 412 is provided along the limiting structure 411 in a circle on the inner side of the frame body 41. The rear cover plate 43 abuts against the connecting portion 412 to make the LED light strip 44 irradiate the light emitting panel 42. A number of through holes 430 are provided on the rear cover plate 43. A number of pressing rods 450 corresponding to the through holes 430 are provided at the bottom of the frame cover 45. When the frame cover 45 is fixed to the frame body 41, the pressing rods 450 at the bottom pass through the through holes 430 and press against the rear side of the light emitting panel 42 to form a limit. Specifically, the frame cover 45 is fixed to the connecting portion 412 by bolts to fix the rear cover plate 43.

[0027] Further, since the third rotating seat 53 needs to be fixed in the middle of the lamp head 4, a fixing beam 46 is further provided in the middle at the rear side of the lamp head 4. Both ends of the fixing beam 46 are fixed to the frame body 41. The third rotating seat 53 is connected above the fixing beam 46. Specifically, when the rear cover plate 43 is installed, the fixing beam 46 abuts against the upper side of the rear cover plate 43. The front and rear ends of the fixing beam 46 are fixed to the connecting portion 412 by bolts. After the frame cover 45 is installed, the fixing beam 46 and the rear cover plate 43 are pressed and fixed together.

[0028] Further, in order to improve the diversity of light irradiation, a backlight is further provided on the rear cover plate 43. Specifically, at least one installation groove 431 extending along the length direction is provided on the rear cover plate 43 and a backlight plate 47 is fitted to the notch of the installation groove 431. A backlight LED light strip 48 irradiating towards the rear side of the lamp head 4 is provided in the installation groove 431. The backlight plate 47 is adhered to the notch of the installation groove 431 by an adhesive to cover the backlight LED light strip 48.
