[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] Combine Figure 1 - Figure 5 A lamp structure that is easy to wire includes a lampshade 1, the top of the lampshade 1 is connected to the wire 2, the lampshade 1 is located at the bottom of the ceiling 3, three connecting chains 5 are fixedly connected to the top of the lampshade 1, the same end of the two connecting chains 5 is fixedly connected to a connecting disk 6, the top of the connecting disk 6 is fixedly connected to two connecting blocks 1 7, the bottom of the ceiling 3 is fixedly connected to two connecting blocks 2 8, a fixed pulley 9 is rotatably connected between the two connecting blocks 2 8, a movable pulley 14 is rotatably connected between the two connecting blocks 1 7, the bottoms of the two connecting blocks 2 8 are fixedly connected to a connecting frame 10, the bottom of the connecting frame 10 is fixedly connected to a connecting ring 11, the inside of the connecting ring 11 is connected to a connecting ring 2 12, and the outer surface of the connecting ring 2 12 is fixedly connected to a cable 13.

[0026] During actual operation, when the lamp tube needs to be replaced or installed, the cable 13 is loosened and lengthened, so that the fixed pulley 9 and the lampshade 1 and the parts fixedly connected thereto move downward together until they move to the ground. At this time, the wire 2 can be connected to the external power supply line, and the lamp tube can be replaced and installed. When the suspended lamp is installed, there is no need to use external climbing tools to install the lamp, which not only facilitates the installation of the suspended lamp, but also facilitates the connection of the wire 2 to the external power supply line.

[0027] It should be noted that the length of the wire 2 is longer than the length between the lampshade 1 and the ground, and a certain length of the wire 2 needs to be reserved.

[0028] See Figure 1 - Figure 3 The two connecting chains 5 on both sides are symmetrical to each other along the connecting chain 5 in the middle, and the cable 13 is wound around the movable pulley 14 and the fixed pulley 9.

[0029] See 1 and Figure 4 A fixing box 4 is provided on one side of the lampshade 1. The interior of the fixing box 4 is rotatably connected to a wire pulley 16. A connecting groove 15 is provided inside the fixing box 4 through the outer surface. The fixing box 4 is installed on the external wall and close to the ground.

[0030] See Figure 1 and Figure 4 One end of the cable 13 passes through the connecting groove 15 and is wound around the outer surface of the pulley 16.

[0031] See Figure 4 and Figure 5 A hexagonal groove 18 is provided at the rear part of the interior of the fixed box 4, and a hexagonal groove 18 is also provided at the rear part of the interior of the spool 16. A hexagonal rod 17 is slidably connected to the interior of the two hexagonal grooves 18. One end of the hexagonal rod 17 passes through the interior of the spool 16 and the front part of the fixed box 4. A rotating groove 22 is provided inside the wall of the fixed box 4. The outer surface of the round rod 19 is located inside the rotating groove 22 and passes through the front part of the fixed box 4 for rotation. A ring 20 is provided for rotation. The outer surface of the ring 20 is located inside the rotating groove 22 and is symmetrically fixedly connected to two plug-ins 21. A slot 23 is provided at the front part of the fixed box 4.

[0032] Specifically, when the lampshade 1 needs to be lowered, the ring 20 is first rotated 90 degrees clockwise so that the plug 21 is facing the slot 23, and the round rod 19 is pulled to slide the hexagonal rod 17. The hexagonal rod 17 is separated from the hexagonal slot 18 provided at the rear part of the fixing box 4, and the two plugs 21 and the ring 20 slide along the slot 23 to the front of the fixing box 4. At this time, the round rod 19 is rotated counterclockwise again, and the hexagonal rod 17 cooperates with the hexagonal slot 18 provided inside the wire wheel 16 to drive the wire wheel 16 to rotate counterclockwise together, thereby loosening and lengthening the wire wheel 13. When the lampshade 1 needs to be raised, the round rod 19 is rotated clockwise to drive the pulley 16 to rotate clockwise, and the cable 16 is gradually wound around the outer surface of the pulley 16, thereby lifting the lampshade 1. When it is raised to a predetermined height, the round rod 19 is pushed again to reconnect the hexagonal rod 17 with the hexagonal slot 18 opened at the rear part of the fixing box 4, and the ring 20 is rotated ninety degrees counterclockwise so that the plug 21 is no longer facing the slot 23, thereby making the round rod 19 unable to slide anymore, and the pulley 16 unable to rotate. Therefore, its cable 13 cannot move, thereby fixing the height of the lampshade 1.

[0033] See Figure 4 and Figure 5 The slot 23 is connected to the rotating groove 22, and the ring 20 and the two insert blocks 21 are adaptively matched with the slot 23 as a whole.

[0034] See Figure 4 The length of the hexagonal rod 17 is less than the overall length of the two hexagonal slots 18 .

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
