An office lighting device with adjustable height, as shown in fig. 1-5, comprises a roof 1, a suspended ceiling 21 arranged on the roof, and a mounting rack 4 arranged on the roof above the suspended ceiling, the invention has the innovation that: the bottom surface of the mounting frame is provided with at least two hoisting rods 3, the lower end of each hoisting rod is provided with a bending edge 18, each bending edge is internally provided with a guide pillar 13 capable of vertically sliding, the upper ends of all the guide pillars are provided with limiting mechanisms 12, and the lower ends of all the guide pillars are connected with the upper end surface of a lamp 22. The bottom surface of the mounting rack is provided with a vertical screw rod 10 which is sleeved in a nut 14 arranged on the upper end surface of the lamp and is driven by a motor 2 to rotate.
In this embodiment, the light fixture may be embedded in the opening of the ceiling plate, or may be directly embedded in the opening 34 of the ceiling framework in the same size and shape as the ceiling plate.
The number of the hoisting rods can be 2-4, preferably 2, and the hoisting rods are symmetrically arranged, wherein the two symmetrical hoisting rods can be symmetrically arranged at two symmetrical diagonal positions of a square or a rectangle, and can also be symmetrically arranged at two symmetrical sides of the square or the rectangle. The limiting mechanism is a limiting block which is integrally or detachably arranged at the upper end part of each guide pillar. The limiting block can be directly meshed and connected into the upper end of the guide pillar, or embedded into the upper end of the guide pillar and fixed with the guide pillar and the guide pillar through bolts.
The lower end of the guide post can be in limited sleeving with a rotating cover 19 with an internal thread, an installing post with an external thread is arranged at the position aligned with the upper end face of the lamp, when the guide post is pressed on the upper end face of the installing post, the rotating cover is rotated to enable the internal thread of the rotating cover to be in meshing sleeving with the external thread of the installing post, and after all the rotating covers are screwed down, the guide post and the lamp are stably connected. Of course, a fixing structure in which the guide post is embedded in the mounting post and connected with the mounting post through a bolt is also possible.
The upper end of the screw is rotatably arranged in a hoisting frame 7 arranged on the bottom surface of the mounting frame, the outer edge of the screw below the hoisting frame is in driving connection with a motor through a driving mechanism 11, the outer edge of the screw below the driving mechanism is sleeved with a nut, the nut is embedded in a nut frame 16 arranged on the upper end surface of the lamp, and a supporting leg 17 at the lower end of the nut frame is connected with the upper end surface of the lamp. The concrete structure is as follows: any side edge of the hoisting frame is provided with an opening 30, the opening is used for embedding the screw rod into the hoisting frame, a bearing groove 26 is arranged on the hoisting frame beside the opening, a bearing is embedded in the bearing groove, a rotating ring of the bearing is pressed on the bottom surface of an end plate 8 arranged at the upper end part of the screw rod, and the screw rod downwards passes through a round hole 35 of the hoisting frame below the bearing groove and then downwards extends and is sleeved with a screw nut. To ensure the safety of the upper end of the screw, a stop plate 31 may be mounted at the opening 30 by means of the bolt 29 to limit the bearing in the bearing groove.
The nut frame upper end is provided with nut groove 28 and mounting groove 27 from top to bottom, and the nut is embedded in nut groove and the mounting groove, and the mounting panel 15 that the nut outer fringe was counterpointed and is set up is embedded in the mounting groove of nut side.
