[0002] Chandeliers are high-end decorative lighting fixtures suspended from indoor ceilings. Whether suspended by wires or iron rods, they cannot be hung too low, as this would obstruct normal vision or cause glare. Therefore, existing chandeliers are usually designed to be adjustable, meaning that during installation, the height of the chandelier can be adjusted according to the height of the room to ensure the lighting height of the chandelier and facilitate indoor lighting.
[0003] Existing adjustable chandeliers mainly consist of a lamp body, a mounting box, and an adjustment mechanism located within the mounting box. During use, the adjustment mechanism is used to adjust the height and horizontal position of the lamp body for convenient operation. However, existing mounting boxes are typically fixed to the ceiling using bolts. When the internal adjustment mechanism or other components require maintenance, the bolts must be removed first, followed by disassembling the mounting box. Therefore, this presents two problems: firstly, it makes disassembly inconvenient and inefficient; secondly, during installation, installers must manually support the mounting box, making installation difficult, time-consuming, and labor-intensive, thus hindering quick assembly and disassembly, and consequently impacting the lamp's usability and maintenance.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 1-5As shown, an adjustable chandelier includes a mounting box 2. The top of the mounting box 2 is provided with a fixing plate 1, and the bottom is provided with a lamp post 3. A lamp holder 4 is installed at the bottom of the lamp post 3. A light bulb and a lampshade 5 are detachably installed at the bottom of the lamp holder 4, and the light bulb is inside the lampshade 5. The mounting box 2 is also provided with a driving component that moves and adjusts the lamp post 3. It also includes a connection structure for quick assembly and disassembly between the mounting box 2 and the fixing plate 1. The connection structure includes a connecting ring 10 installed at the bottom of the fixing plate 1 and insert blocks 11 fixed on both sides of the mounting box 2. The connecting ring 10 is fitted on the top of the mounting box 2, and slots 13 for inserting the insert blocks 11 are opened on both sides of the inner wall of the connecting ring 10. The connecting ring 10 is also provided with a locking component 14 for limiting and fixing the insert blocks 11 to the connecting ring 10.
[0017] Depend on Figure 2 and Figure 4 It is known that the driving component includes two support plates 9 symmetrically fixed inside the mounting box 2, a lead screw 7 is installed between the two support plates 9, and a motor 6 for driving the lead screw 7 to rotate is fixed on one side of one of the support plates 9. A lead screw seat 8 is connected to the lead screw 7 by thread. The top end of the upper rod 31 is fixed to the bottom of the lead screw seat 8. An oblong hole for the upper rod 31 to move is opened at the bottom of the mounting box 2.
[0018] Depend on Figures 4-8 It is known that the locking assembly 14 includes a mounting cavity 145 opened in the connecting ring 10 and a movable pull plate 141 located at the bottom of the connecting ring 10. A first spring 146 is fixed to the inner wall of the mounting cavity 145, and one end of the first spring 146 is connected to a moving block 144 that can move along the mounting cavity 145. A locking block 142 that can extend to the outside of the mounting cavity 145 is installed on one side of the moving block 144. A locking groove 143 for the locking block 142 to be inserted is opened in the insert block 11. A sliding rod is connected between the pull plate 141 and the moving block 144. A slot 147 for the sliding rod to move is opened on the connecting ring 10.
[0019] When in use, the chandelier can be connected to the power supply first, and then the fixing plate 1 can be installed on the ceiling with fasteners (such as expansion bolts) to complete the installation of the chandelier. Then, the chandelier can be turned on by the external switch (installed on the wall), and the light bulb in the lampshade 5 will emit light to provide indoor lighting. Furthermore, during the use of the chandelier, the motor 6 can drive the lead screw 7 to rotate, so that the lead screw 7 drives the lamp post 3 to move horizontally through the lead screw seat 8 that cooperates with it. Then, the lamp post 3 drives the lamp seat 4 and the bulb on it to move horizontally, thereby adjusting the lighting position of the chandelier, increasing the lighting range of the chandelier, and making the use of the chandelier more convenient. When the drive component needs maintenance, the two pull plates 141 on the same side can be pulled towards each other, causing the moving block 144 to move along the mounting cavity 145 and drive the locking block 142 into the mounting cavity 145. At this time, the moving block 144 compresses the first spring 146, causing the first spring 146 to contract. Then, the mounting box 2 is pulled down to remove the insert block 11 from the slot 13, thus disassembling the mounting box 2 from the fixing plate 1. Then, the drive component in the mounting box 2 can be maintained. In the maintenance process, the moving block 144 is first pulled by the pull plate 141, causing the moving block 144 to drive the locking block 142. The fastening block 142 is retracted into the mounting cavity 145, and then the mounting box 2 is inserted into the bottom of the fixing plate 1 through the insert block 11 and the slot 13. Then, the pull plate 141 is released, so that the moving block 144, under the action of the first spring 146, inserts the locking block 142 into the locking groove 143 to lock and limit the insert block 11, thus completing the installation between the mounting box 2 and the fixing plate 1. This enables quick assembly and disassembly between the mounting box 2 and the fixing plate 1, facilitating the wiring and power connection of the chandelier and the maintenance of the internal components of the mounting box 2. This, in turn, helps to improve the installation and maintenance efficiency of the chandelier, making it easier to use.
[0020] Furthermore, such as Figures 4-6 As shown, an anti-detachment block 12 is integrally formed on one side of the insert block 11, and a slot is provided on the connecting ring 10 for inserting the anti-detachment block 12, and the slot is connected to the slot 13.
[0021] When the insert 11 is inserted into the slot 13, the anti-disengagement block 12 can be inserted into the slot cavity to limit the insert 11, so that the mounting box 2 can be hung on the bottom of the fixing plate 1 through the connecting ring 10, thereby facilitating the installation of the chandelier.
[0022] Meanwhile, in this embodiment, such as Figures 1-3 As shown, the lamp post 3 includes an upper rod 31, a connecting rod 32, and a lower rod 33 connected end to end. Each end of the connecting rod 32 and the lower rod 33 is provided with a threaded portion 34, and the inner walls of each end of the upper rod 31 and the connecting rod 32 are provided with internal threads that mate with the threaded portions 34. Specifically, the upper rod 31, the connecting rod 32, and the lower rod 33 are hollow, and both the upper rod 31 and the fixing plate 1 are provided with wire holes to facilitate wire threading and power connection for the chandelier.
[0023] During the use of the chandelier, the height of the chandelier can be adjusted according to the height of the room. When the room height is low, the lower rod 33 can be directly screwed to the bottom of the upper rod 31 through the screw connection part 34. If the room height is high, the connecting rod 32 can be screwed to the bottom of the upper rod 31 through the screw connection part 34, and then the lower rod 33 can be screwed to the bottom of the connecting rod 32. This allows the height of the lamp holder 4 to be adjusted, which facilitates the height adjustment of the chandelier and is beneficial to the use of the chandelier.
[0024] Additionally, in this embodiment, as Figures 4-7As shown, the insert block 11 is also provided with a snap-fit member 15 to limit the locking block 142. The snap-fit member 15 includes a cavity 151 opened inside the insert block 11. A second spring 152 is fixed on the inner wall of the cavity 151. One end of the second spring 152 is connected to a movable plate 153 that can move along the cavity 151. A snap-fit block 154 that can extend into the locking groove 143 is installed on one side of the movable plate 153. A snap-fit hole 155 for snap-fit block 154 is opened on one side of the locking block 142.
[0025] When the locking block 142 is inserted into the locking groove 143 in the insert block 11 and the insert block 11 is locked in place, the locking block 154 corresponds to the locking hole 155 and is locked into the locking hole 155 under the action of the second spring 152, so as to lock the locking block 142 in place and limit it, so that the locking block 142 is stably inserted into the locking groove 143, thereby increasing the stability of the locking block 142 when it is inserted into the locking groove 143, and thus achieving a stable installation between the mounting box 2 and the fixing plate 1. When the mounting box 2 and the fixing plate 1 are disassembled, the locking block 142 is pulled out from the locking groove 143 by the pull plate 141. At this time, the locking block 154 is subjected to force and squeezes the second spring 152, causing the second spring 152 to contract and drive the locking block 154 to retract into the locking hole 155, thereby releasing the limitation on the locking block 142 and facilitating the disassembly of the mounting box 2 and the fixing plate 1.
[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
