[0001] The utility model relates to the technical field of lighting fixtures, in particular to an adjustable pendant lamp. Background Art

[0002] With the continuous subdivision and development of the needs of modern life, when users purchase lamps, in addition to considering the basic lighting function, they also pay attention to the role of the appearance of the lighting fixtures in creating an atmosphere.

[0003] A pendant lamp is a lamp suspended by an electric wire. To meet the requirements of different ceiling heights and installation heights, an adjustment device is needed to adjust the height of the pendant lamp and keep the pendant lamp hovering at a fixed height so that the height of the pendant lamp can be adjusted at any time.

[0031] In the description of the present utility model, unless otherwise clearly defined, words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0032] The following will be combined with Figures 1 to 3 to illustrate the embodiments of the present utility model.

[0033] This embodiment relates to an adjustable pendant lamp, which has the advantage of convenient adjustment of the hovering position.

[0034] An adjustable pendant lamp in this embodiment includes:

[0035] A fixing base 1, fixedly connected to the ceiling;

[0036] A wire winder 4, arranged on the fixing base 1;

[0037] The wire 2 has a tendency to be retracted driven by the reel 4, and the wire 2 includes a free end 21 led out from the reel 4;

[0038] The suspension wire block 3 is fixedly connected to the ceiling. An installation space 30 is provided in the suspension wire block 3. A horizontal wire inlet hole and a vertical wire outlet hole are provided on the suspension wire block 3. The wire inlet hole is located above the wire outlet hole, and both the wire inlet hole and the wire outlet hole communicate with the installation space 30;

[0039] The reversing wheel 33 is arranged in the installation space 30. The reversing wheel 33 covers the wire outlet hole. A wire routing gap is left between the reversing wheel 33 and both the wire inlet hole and the wire outlet hole. The free end 21 sequentially enters the installation space 30 from the wire inlet hole, winds around the reversing wheel 33, and then leads out downward from the wire outlet hole;

[0040] The lamp 5 is fixedly connected to the free end 21, and the lamp 5 is electrically connected to the wire 2.

[0041] Since the reversing wheel 33 covers the wire outlet hole, when the wire 2 routes along the outer periphery of the reversing wheel 33, a large frictional resistance is generated at the orifice of the wire outlet hole of the wire 2, offsetting the gravity of the lamp 5, so that the lamp 5 can hover. When adjusting, only by pulling the lamp 5 in different ways can the lamp 5 be raised or lowered, and the hovering position can be adjusted conveniently.

[0042] Adjusting the height of the lamp 5 is divided into two cases: upward adjustment and downward adjustment. The operation of downward adjustment is as follows: First, hold the lamp 5 with your hand and slowly pull it down, so that the wire 2 overcomes the wire retracting force provided by the reel 4. After pulling it down to the required position, when the frictional force between the wire 2 and the orifice of the wire outlet hole cancels out the wire retracting force, the lamp 5 will hover at the adjusted position. The operation of upward adjustment is as follows: First, hold the lamp 5 with your hand and quickly pull it down a short distance, and then quickly release the lamp 5. The lamp 5 can rise a short distance. After that, when the frictional force between the wire 2 and the orifice of the wire outlet hole cancels out the wire retracting force, the lamp 5 will hover at the upper position. Among them, the reason why quickly pulling down and releasing the lamp 5 can make the lamp 5 rise a short distance is that quickly pulling down the lamp 5 makes the wire 2 have a certain speed, and the frictional state between the wire 2 and the orifice of the wire outlet hole changes from static friction to dynamic friction. Under the action of the wire retracting force, the wire 2 can decelerate while rising until the rising speed of the wire 2 decelerates to a stop.

[0043] In order to reduce the wear of the wire 2, the reversing wheel 33 is rotatably arranged in the installation space 30. The reversing wheel 33 is rotatably installed in the installation space 30. The friction between the wire 2 and the reversing wheel 33 is rolling friction, and the wear of the wire 2 caused by the reversing wheel 33 is relatively small.

[0044] Specifically, a spring is further provided inside the wire reel 4. The fixed end of the wire 2 is fixedly connected to one end of the spring, and the other end of the spring is fixed inside the wire reel 4. The spring provides the elastic force for the recovery of the wire 2. In this embodiment, the spring is a scroll spring. A scroll spring is a spring formed by winding an equal cross-section slender material into a planar spiral shape, and is usually used to generate a torsional moment within its own plane to store energy. Compared with a cylindrical spring, the scroll spring has a smaller stiffness and a variable stiffness characteristic, and generally works under static load, and is suitable for application scenarios that require large loads and small spaces. After applying the scroll spring to this pendant lamp, when the lead-out length of the wire 2 changes, the change in the wire-receiving force (i.e., the pulling force on the lamp 5) is smaller, so that the lamp 5 can more stably maintain the hovering state before and after adjustment. After adopting the scroll spring, if it is impossible to lift the pendant lamp by quickly pulling it down, the pendant lamp can be directly held by hand and try to lift the pendant lamp directly.

[0045] To further reduce the wear of the wire 2, the wire hanging block 3 includes a fixed block 31 and a rotating block 32. The fixed block 31 is fixedly connected to the ceiling, the rotating block 32 is rotatably connected to the fixed block 31, and the installation space 30 is arranged inside the rotating block 32. Since the installation space 30 is arranged inside the rotating block 32, when the wire 2 enters from the wire inlet hole, the rotating block 32 can rotate around the fixed hole to adapt to the position of the wire 2, reducing the wear of the wire 2.

[0046] To facilitate the adaptation to lamps 5 of different weights, the pendant lamp further includes a cushion member 34. The cushion member 34 is located inside the wire outlet hole, and the cushion member 34 is detachably connected to the rotating block 32. After the cushion member 34 is arranged inside the wire outlet hole, the wire 2 abuts against the cushion member 34 at the wire outlet hole, and the frictional force of the wire 2 is provided by the cushion member 34. The magnitude of the frictional force is affected by the thickness of the cushion member 34. When it is necessary to replace a lighter lamp 5, replacing the cushion member 34 with a greater thickness can increase the frictional force of the wire 2 to balance the wire-receiving force, improving the adaptability of this pendant lamp.

[0047] The rotating block 32 is further provided with a clamping block. The cushion member 34 includes a first clamping block 341, a cushion block 342, and a second clamping block 343. The cushion block 342 is located inside the wire outlet hole. The first clamping block 341 and the second clamping block 343 are respectively connected to the upper end and the lower end of the cushion block 342. The first clamping block 341 and the second clamping block 343 jointly clamp the clamping block. The cushion member 34 is detachably connected in the form of clamping the clamping block by the first clamping block 341 and the second clamping block 343, which can conveniently realize the installation and disassembly of the cushion member 34. In this embodiment, a hollow hole 321 communicating with the installation space 30 is provided on the circumferential side wall of the rotating block 32. The clamping block is the part between the lower side of the hollow hole 321 and the bottom surface of the rotating block 32. The first clamping block 341 abuts against the lower side wall of the hollow hole 321, and the second clamping block 343 abuts against the bottom wall of the rotating block 32.

Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present utility model. These equivalent variations or substitutions are all included within the scope defined by the claims of the present utility model.
