The cross section of the sliding groove is a dovetail groove, and the cross section of the sliding block is a dovetail block.

And a limit switch is fixed at the bottom end of the sliding chute, and is connected with the driving motor and controls the driving motor to stop working.

The inhaul cable is a metal inhaul cable.

The utility model has the positive effects that: the lamp holder is reasonable in structure and convenient and fast to operate, the adjusting arm can rotate around the rotating shaft as a center according to needs, so that the illumination range of the lamp holder is adjusted, and the lamp holder is stable and reliable to use, strong in applicability and good in practicability.

Drawings

In order that the present disclosure may be more readily and clearly understood, reference is now made to the following detailed description of the present disclosure taken in conjunction with the accompanying drawings, in which:

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic structural diagram of the utility model after adjustment.

Detailed Description

(example 1)

FIGS. 1 and 2 show an embodiment of the present invention, wherein FIG. 1 is a schematic structural view of the present invention; FIG. 2 is a schematic view of the structure of the present invention after adjustment

See fig. 1 and 2, a support arm type ceiling lamp, including inhaling footstock 1, lamp stand 2 and lamp holder 3, lamp holder 3 is fixed on lamp stand 2 inhale the symmetrical side of footstock be fixed with support arm 4 the both ends of support arm are fixed with drive roller 5 respectively the lamp stand with inhale and be provided with regulating arm 6 between the footstock the lamp stand with inhale, the top of regulating arm is passed through rotation axis 7 and is connected inhale the bottom surface center of footstock, the top surface of lamp stand is connected through round pin axle 8 the bottom of regulating arm spout 9 has been seted up respectively to the symmetrical side of regulating arm be provided with slider 10 in the spout, for the stability that improves the use, the cross-section of spout is the forked tail groove, just the cross-section of slider is the forked tail shape piece. A return spring 11 is fixed between the slide block and the top end of the sliding groove, a driving motor 12 is fixed on the ceiling seat, a pull cable 13 is fixed between the slide block and the driving motor, the middle of the pull cable 13 is located on the transmission roller, and in the embodiment, the pull cable is a metal pull cable. One end of the inhaul cable is fixed on the sliding block, the other end of the inhaul cable is fixed on a main shaft of the driving motor, and a control switch 14 for controlling the driving motor to rotate forwards or backwards is fixed on the ceiling seat.

When driving motor is rotatory, one of them cable is in the shrink state, another cable is in the extension state, two sliders can remove in the spout under the pulling effect of cable this moment, one rises in the spout, another will down in the spout to make the regulating arm rotatory, when driving motor reversal, the cable is not hard up, in this embodiment, control switch is hand switch or remote switch, for prior art's structure, and driving motor also is prior art's structure, its connected mode with control switch also is prior art's conventional mode. In the embodiment, the positions of the rotating shafts of the two inhaul cables at the driving motor are different, and the two inhaul cables are separated at a certain interval, so that the two inhaul cables cannot influence each other when being wound and loosened.
