A guide block 322 is fixedly welded on the end surface of the coiling ring 32, and a guide wheel 33 for changing the direction of the lifting rope 12 is rotatably connected on the guide block 322; the end face of the winding ring 32 is also fixedly welded with a guide frame 35, one end of the guide frame 35, which is far away from the winding ring 32, is close to the axis of the winding ring 32, the end part of the guide frame 35, which is far away from the winding ring 32, is fixedly connected with a rope guiding rod 351, and the guide frame 35 and the guide block 322 are located on the same side of the winding ring 32. From the power end of the lifting rope 12, the lifting rope 12 is firstly fixed with the mounting cover 2, then bypasses the limit stop 341, departs from the limit stop 341, reaches the guide block 322 and surrounds to the circumferential surface of the guide wheel 33, departs from the guide wheel 33, reaches the rope guide 351 and is lapped on the rope guide.

As shown in fig. 1, a driving motor 31 is fixedly installed in the installation cover 2, and the driving motor 31 is controlled by an external switch to start, stop or turn, and the control mode may be wireless signal transmission or wired electric connection. The output shaft of the driving motor 31 is coaxially and fixedly connected with a driving gear 311, a toothed ring portion 321 is integrally formed on one side of the outer ring of the winding ring 32, the driving gear 311 is meshed with the toothed ring portion 321, and the driving gear 311 is driven by the driving motor 31 to rotate so as to control the rotation and the static of the winding ring 32.

The guide wheel 33 comprises a main wheel 331, an auxiliary wheel 332 and a direction-changing wheel 333, wherein the rotation planes of the main wheel 331 and the auxiliary wheel 332 are parallel to the rotation plane of the winding ring 32, the main wheel 331 and the auxiliary wheel 332 are respectively positioned at two opposite sides of the lifting rope 12, and the wheel surfaces of the main wheel 331 and the auxiliary wheel 332 are abutted to the lifting rope 12; the turning plane of the direction-changing wheel 333 is perpendicular to the turning plane of the main wheel 331. The lifting rope 12 leaves the limit stop lever 341 and then goes to the guide wheel 33, passes between the main wheel 331 and the auxiliary wheel 332, and then passes around the direction-changing wheel 333 to reach the rope guide lever 351.

As shown in fig. 1 and 2, if the lifting rope 12 is wound around the main wheel 331 after being wound out of the limit stop 341, and the rotation direction of the winding ring 32 is the direction of the auxiliary wheel 332 relative to the main wheel 331, the winding and unwinding mechanism 3 controls the lifting rope 12 to wind around the limit stop 341, i.e., controls the lamp body 13 to ascend, and if the rope is wound around the main wheel 331 after being wound out of the limit stop 341, and the rotation direction of the winding ring 32 is the direction of the main wheel 331 relative to the auxiliary wheel 332, the winding and unwinding mechanism 3 controls the lifting rope 12 to lead out of the limit stop 341, i.e., controls the lamp body 13 to descend. The retracting mechanism 3 continues to move the lifting rope 12 to the guiding-out limit stop lever 341 until the lifting rope 12 is not wound on the limit stop lever 341 any more, the part of the lifting rope 12 outside the mounting cover 2 is in the state of the longest length, if the winding ring 32 is continuously rotated at the moment, the lifting rope 12 changes the guide wheel 33 wound by the lifting rope 12 (wound on the main wheel 331, changed on the auxiliary wheel 332 or wound on the auxiliary wheel 332, changed on the main wheel 331) along with the trend, and simultaneously changes the working mode of the winding ring 32 under the turning (the guiding-out lifting rope 12 is changed into the winding lifting rope 12).

Since the guide block 322 and the guide frame 35 both rotate synchronously with the winding ring 32, the relative positional relationship between the rope guiding rod 351 and the guide block 322 and the guide pulley 33 is in a relatively stationary state. The adjusting hole 21 is located right below the rope guiding rod 351, and the lifting rope 12 naturally hangs down after passing around the rope guiding rod 351 and passes through the adjusting hole 21.

The implementation principle of the installation structure for ceiling lamp lifting regulation is as follows:

when the lamp body 13 needs to be lifted, the driving motor 31 is started to rotate the winding ring 32, the guide wheel 33 generates a pulling effect on the lifting rope 12, meanwhile, the guide wheel 33 and the guide block 322 rotate along with the winding ring 32 to wind the lifting rope 12 onto the limit stop rod 341, so that the lifting rope 12 is wound, the length of the lifting rope 12 between the installation cover 2 and the lamp body 13 is reduced, and the lamp body 13 is lifted; when the lamp body 13 needs to be lowered, the driving motor 31 is controlled to rotate reversely, the winding ring 32 and the guide wheel 33 both rotate reversely to lead out the lifting rope 12 wound on the limit stop rod 341, and under the action of gravity of the lamp body 13, the lifting rope 12 leaving the limit stop rod 341 finally passes through the adjusting hole 21, so that the length of the lifting rope 12 between the mounting cover 2 and the lamp body 13 is increased, that is, the height of the lamp body 13 is lowered.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
