Description

Technical Field

[0001] The invention relates to the technical field of lamps, and in particular to a chandelier capable of adjusting the height of the lamp. Background Art

[0002] Lamps are a general term for lighting tools, which are divided into chandeliers, table lamps, wall lamps, floor lamps, etc. They refer to appliances that can transmit light, distribute and change the distribution of light from a light source. They include all parts needed to fix and protect the light source except the light source, as well as the line accessories necessary to connect to the power supply.

[0003] Among them, a chandelier is a kind of lamp hanging from the ceiling. Compared with ordinary fluorescent lamps or incandescent lamps, chandeliers can have a better decorative effect. Therefore, in order to enhance the living experience, users often choose chandeliers, which can be hung with wires or iron rods.

[0004] Most chandeliers are hung directly on the ceiling through fixing devices, but people have higher and higher requirements for lighting. The requirements for lighting are different in different usage conditions. For example, when eating at the table, a halo of light needs to be focused on the center of the breakfast table to focus vision and adjust the dining mood. At this time, the chandelier needs to be positioned lower. However, after the meal, when people are chatting at the table, the lower position of the chandelier will affect people's sight. At this time, the chandelier needs to be adjusted upward. In the prior art, the fixed setting of the chandelier affects the practicality and convenience of the chandelier. Summary of the invention

The reserved groove 2 generates suction, which further improves the collection effect of the reserved groove 2 on dust particles, and guides the dust particles into the dust box 3.

[0055] The working principle of the present invention is as follows: when installing the chandelier, the driving motor 9 is fixedly installed in the ceiling, and the mounting ring 14 is movably installed in the ceiling. When people use it in daily life, they turn on the light source inside the chandelier body 1 by controlling the switch to play a lighting role. When people need to adjust the height of the chandelier body, they start the driving motor 9 by controlling the switch, thereby driving the driving shaft 10 to rotate, and the outer wall of the driving shaft 10 is threadedly connected with the inner wall of the telescopic cylinder 11, and the telescopic cylinder 11 is limited by the limiting rod 13, so that the telescopic cylinder 11 moves downward, thereby driving the chandelier body 1 to move downward, and then adjusting the height of the light source;

[0056] When the driving shaft 10 rotates, the driving gear 12 is driven to rotate, and the first tooth plate 27 is initially meshed with the driving gear 12, so the first tooth plate 27 is displaced, thereby driving the limit shaft 26 to be displaced, and through the cooperation between the limit block 24 and the limit groove 28, the limit shaft 26 moves a certain distance and then rotates ninety degrees, thereby driving the fixing rod 29 to rotate with the limit shaft 26 as the center of the circle;

[0057] When the telescopic cylinder 11 moves downward, the second tooth plate 35 is driven to move downward, and the second tooth plate 35 is meshed and connected with the second transmission gear 32, so the second transmission gear 32 rotates, thereby driving the second transmission shaft 31 to rotate, and the second transmission shaft 31 and the contraction cylinder 33 are connected by a synchronous belt, so the contraction cylinder 33 rotates synchronously, and because the inner wall of the contraction cylinder 33 is threadedly connected with the outer wall of the telescopic column 34, the telescopic column 34 moves, and at the same time, the limit shaft 26 and the fixed rod 29 are turned over, so that the first tooth plate 27 is separated from the driving gear 12, and the inner wall spring of the mounting block 25 pulls the limit shaft 26 to reset and move, and because the telescopic column 34 blocks the fixed rod 29, the limit shaft 26 is not reset;

[0058] When people turn off the light source inside the chandelier body 1 and start the driving motor 9 to reset the chandelier body 1, the second tooth plate 35 is driven to reset, so that the telescopic column 34 is reset and moved, and the blocking of the telescopic column 34 on the fixed rod 29 is released, and the spring pulls the limit shaft 26 to reset and move, thereby driving the first tooth plate 27 to move;

[0059] When the first tooth plate 27 moves, the first tooth plate 27 is meshed and connected with the first transmission gear 22, so the first transmission gear 22 rotates, thereby driving the first transmission shaft 21 to rotate, and then driving the transmission bevel gear 23 to rotate, and the transmission bevel gear 23 is meshed and connected with the linkage bevel gear 19, so the linkage bevel gear 19 rotates, thereby driving the linkage shaft 18 to rotate, because the linkage shaft 18 is connected to the mounting ring 14 through synchronous driving, the mounting ring 14 rotates, thereby driving the connecting rod 15 to rotate, and then driving the scraper 16 to move, and the scraper 16 cleans the outer wall of the upper end of the chandelier body 1 when moving, and the scraper 16 is inclined, and the dust particles pushed by the scraper 16 are displaced toward the reserved groove 2, and the reserved groove 2 collects the dust particles;

[0060] When the scraper 16 is displaced, the support rod 17 is driven to move, and after the chandelier body 1 is reset, one end of the support rod 17 enters between the two groups of protrusions on the outer wall of the movable gear ring 14, thereby driving the movable gear ring 14 to rotate, and the inner wall of the movable gear ring 14 is meshed and connected with the movable gear 6, so the movable gear 6 rotates, thereby driving the movable shaft 5 to rotate, and then driving the fan 7 to rotate, so that suction is generated in the installation groove 8, and the suction is guided to the reserved groove 2 through the dust box 3. The reserved groove 2 generates suction, which further improves the collection effect of the reserved groove 2 on dust particles, and guides the dust particles into the dust box 3, thereby completing the cleaning of the upper end outer wall of the chandelier body 1, and improving the convenience of cleaning the upper end outer wall of the chandelier body 1;

[0061] The present invention arranges a driving shaft 10 and a telescopic cylinder 11. The driving shaft 10 rotates to drive the telescopic cylinder 11 to move, thereby adjusting the height of the chandelier body 1, thereby improving the practicality and convenience of the chandelier. The scraper 16 is arranged to continue to clean the upper end of the chandelier body 1, thereby avoiding people from climbing up and down to clean the chandelier, thereby improving the convenience of cleaning the chandelier.
