Description

Technical Field

[0001] The utility model belongs to the technical field of indoor lighting, and particularly relates to a lighting device with adjustable lighting range. Background Art

[0002] At present, the role of lighting fixtures is not limited to lighting, but also the eyes of the home. More often, it plays a decorative role. There are many varieties of lighting fixtures, including chandeliers, ceiling lamps, table lamps, and floor lamps.

[0003] Existing indoor lighting table lamps usually have fixed bulbs, which makes the bulbs unable to be adjusted, so that the lighting range of the table lamp is fixed. When the lighting range needs to be expanded, the main light in the room needs to be turned on again, which is inconvenient to operate and makes the table lamp inconvenient to use and cannot meet the needs of users. Therefore, we propose a lighting device with adjustable lighting range. Utility Model Content

[0004] The purpose of the utility model is to provide a lighting device with adjustable lighting range, by setting an adjustment component, specifically, rotating the handle to drive the threaded rod to rotate, then the threaded ring drives the lifting column to move upward or downward, and drives the light bulb to move together through the lamp holder, so as to adjust the lighting range. It can be adjusted according to different needs of users, and the operation is convenient. It solves the problem that the light bulbs of existing interior lighting table lamps are usually fixed, so that the light bulbs do not have the adjustment function, and the lighting range of the table lamp is fixed. When it is necessary to expand the lighting range, the main light in the room needs to be turned on again, which is inconvenient to operate.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a lighting device with adjustable lighting range, comprising a base, a support frame fixedly connected to the top of the base, an adjustment component arranged above the support frame, a connecting block fixedly connected to the top of the support frame, the adjustment component comprising an adjustment seat, a lampshade fixedly connected to the bottom of the adjustment seat, a fixed block fixedly connected to the top of the adjustment seat, a turning handle arranged above the fixed block, and the adjusting component is arranged, specifically, the turning handle is rotated to drive the threaded rod to rotate, and the threaded ring drives the lifting column to move upward or downward, and drives the light bulb to move together through the lamp socket, so as to adjust the lighting range, and can be adjusted according to different needs of users, and is easy to operate.

[0007] Furthermore, a movable groove is provided inside the adjustment seat, and the fixed block is hollowed out. The inner wall of the movable groove is slidably connected to a lamp socket, and a light bulb is fixedly connected to the bottom of the lamp socket. The lamp socket will drive the light bulb to move when it moves. When the light bulb moves downward, it will move away from the lampshade, thereby increasing the lighting area. When the light bulb moves upward, it will move closer to the lampshade, thereby reducing the lighting area.

[0008] Furthermore, a lifting column is fixedly connected to the top of the lamp socket, the lifting column is hollow, and three limiting grooves are opened on the outer surface of the lifting column. A threaded ring is fixedly connected to the top of the inner wall of the lamp socket. When the lifting column moves, the limiting groove will slide on the stabilizing frame, which can limit the lifting column and make the movement more stable.

[0009] Furthermore, a threaded rod is fixedly connected to the bottom center of the throttle, and a stabilizing frame is rotatably connected to the bottom of the threaded rod. An annular groove is provided at the bottom of the throttle, and the outer surface of the stabilizing frame is fixedly connected to the inner wall of the movable groove provided inside the adjustment seat. The outer surface of the stabilizing frame contacts the inner wall of the limiting groove, and the annular groove supports and limits the throttle by cooperating with the limiting ring, so that the throttle will not deviate when rotating in the original position.

[0010] Furthermore, the inner wall of the annular groove is rotatably connected to a limit ring, the bottom of the limit ring is fixedly connected to the top of the fixed block, the bottom of the threaded rod passes through the threaded ring and extends to the outside, the outer surface of the threaded rod is threadedly connected to the inner wall of the threaded ring, and the rotation of the threaded rod will drive the lifting column to move upward or downward through the threaded ring, thereby adjusting the position of the light bulb.

[0011] Furthermore, a connecting block 2 is fixedly connected to the right side of the adjustment seat, and a rotating hole is opened inside the connecting block 1 and the connecting block 2, and a rotating shaft is rotatably connected inside the rotating hole. A plurality of rubber protrusions are fixedly connected to the outer surface of the rotating shaft, and the outer surface of the rubber protrusions contacts the inner wall of the rotating hole. Since the rubber protrusions on the surface of the rotating shaft are made of rubber material and the surface is uneven, the friction force can be increased, so that after the adjustment seat drives the connecting block 2 to rotate, it will not be affected by the friction force and will not be offset by gravity, so that the adjustment seat is fixed, and the lighting range can be adjusted again.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model sets an adjustment component, specifically, the threaded rod is rotated by rotating the handle, and the threaded ring drives the lifting column to move upward or downward, and drives the light bulb to move together through the lamp holder. When the light bulb moves downward, it moves away from the lampshade, thereby increasing the lighting area. When the light bulb moves upward, it moves close to the lampshade, thereby reducing the lighting area. The lighting range can be adjusted according to the different needs of users and is easy to operate.

[0014] 2. The utility model sets a rotating shaft, specifically by pulling the adjustment seat upward or pressing downward, which can drive the connecting block 2 to rotate on the rotating shaft. Since the rubber protrusion is set with rubber material and the surface is uneven, the friction force can be increased, so that after the adjustment seat drives the connecting block 2 to rotate, it will not be affected by the friction force and will not be offset by gravity, so that the adjustment seat is fixed, so that the lighting range can be adjusted again.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] See also Figure 1-6 As shown, the utility model is a lighting device with adjustable lighting range, comprising a base 1, a support frame 11 is fixedly connected to the top, an adjusting component 12 is arranged above the support frame 11, a connecting block 13 is fixedly connected to the top of the support frame 11, the adjusting component 12 comprises an adjusting seat 121, a lampshade 122 is fixedly connected to the bottom of the adjusting seat 121, a fixing block 123 is fixedly connected to the top of the adjusting seat 121, and a turning handle 124 is arranged above the fixing block 123. By setting the adjusting component 12, specifically rotating the turning handle 124 to drive the threaded rod 241 to rotate, the threaded ring 215 drives the lifting column 213 to move upward or downward, and drives the light bulb 212 to move together through the lamp holder 211. When the light bulb 212 moves downward, it is away from the light shade 122, thereby increasing the lighting area. When the light bulb 212 moves upward, it is close to the light shade 122, thereby reducing the lighting area. The lighting range can be adjusted according to different needs of users, and the operation is convenient.

[0027] A movable groove is provided inside the adjustment seat 121 , and the fixed block 123 is hollowed out. A lamp socket 211 is slidably connected to the inner wall of the movable groove, and a light bulb 212 is fixedly connected to the bottom of the lamp socket 211 .

[0028] A lifting column 213 is fixedly connected to the top of the lamp socket 211 . The lifting column 213 is hollowed out and has three limiting grooves 214 on its outer surface. A threaded ring 215 is fixedly connected to the top of the inner wall of the lamp socket 211 .

[0029] A threaded rod 241 is fixedly connected at the center of the bottom of the turning handle 124 , a stabilizing frame 242 is rotatably connected to the bottom of the threaded rod 241 , and an annular groove 243 is formed at the bottom of the turning handle 124 .

[0030] The inner wall of the annular groove 243 is rotatably connected to the limit ring 125, the bottom of the limit ring 125 is fixedly connected to the top of the fixing block 123, the bottom of the threaded rod 241 passes through the threaded ring 215 and extends to the outside, and the outer surface of the threaded rod 241 is threadedly connected to the inner wall of the threaded ring 215.

[0031] A second connecting block 131 is fixedly connected to the right side of the adjustment seat 121. Both the first connecting block 13 and the second connecting block 131 are provided with rotating holes. A rotating shaft 132 is rotatably connected to the rotating hole. A plurality of rubber protrusions 133 are fixedly connected to the outer surface of the rotating shaft 132. The outer surface of the rubber protrusion 133 contacts the inner wall of the rotating hole. By setting the rotating shaft 132, specifically by pulling the adjustment seat 121 upward or pressing it downward, the second connecting block 131 can be driven to rotate on the rotating shaft 132. Since the rubber protrusion 133 is made of rubber material and has an uneven surface, the friction force can be increased, so that after the adjustment seat 121 drives the second connecting block 131 to rotate, it will not be offset by gravity due to the influence of the friction force, so that the adjustment seat 121 is fixed, and the lighting range is adjusted again.

[0032] The outer surface of the stabilizing frame 242 is fixedly connected to the inner wall of the moving groove opened inside the adjusting seat 121 , and the outer surface of the stabilizing frame 242 contacts the inner wall of the limiting groove 214 .

[0033] A specific application of this embodiment is:

[0034] When in use, the threaded rod 241 is driven to rotate by rotating the turning handle 124, and the bottom of the threaded rod 241 rotates on the stabilizing frame 242, thereby improving the stability of the threaded rod 241 when rotating. At the same time, the turning handle 124 rotates on the limiting ring 125, and the limiting ring 125 can limit and support the turning handle 124, so that the turning handle 124 will not deviate when rotating in the original position. The rotation of the threaded rod 241 will drive the lifting column 213 to move upward or downward through the threaded ring 215, and the stabilizing frame 242 will slide in the limiting groove 214 to limit the lifting column 213, so that the lifting column 213 moves in a straight line. The lifting column 213 drives the lamp holder 211 to move upward or downward together, and the bulb 212 moves together. When the bulb 212 moves downward When the bulb 212 moves upward, it moves away from the lampshade 122, thereby increasing the illuminated area. When the bulb 212 moves upward, it moves close to the lampshade 122, thereby reducing the illuminated area. The illumination range can be adjusted according to the different needs of the users. The operation is convenient. By pulling the adjustment seat 121 upward or pressing it downward, the connecting block 131 can be driven to rotate on the rotating shaft 132. At the same time, the rotating hole at the center of the connecting block 131 will contact and rub with the surface of the rubber protrusion 133. Since the rubber protrusion 133 is made of rubber material and has an uneven surface, the friction force can be increased, so that after the adjustment seat 121 drives the connecting block 131 to rotate, it will not be affected by the friction force and will not be offset by gravity, so that the adjustment seat 121 is fixed, thereby adjusting the illumination range again.
