Description

Technical Field

[0001] This utility model belongs to the field of floor lamp technology, and specifically relates to floor lamps. Background Technology

[0002] In traditional floor lamp designs, the lighting fixture is typically fixed to the top of the lamp post. While this design is simple and sturdy, it reveals certain limitations in practical use. Because the fixture lacks a tilting function, users cannot flexibly adjust the direction of the light or the size of the projected area to suit specific lighting needs. This fixed lighting method strictly limits the illuminated area, making it difficult to meet the diverse lighting requirements of various scenarios.

[0003] For example, in different life scenarios such as reading, working, or relaxing, users often need to adjust the direction of the floor lamp's illumination according to the width and position of the desk to achieve the best lighting effect. However, because the lighting fixtures of existing floor lamps cannot be tilted, users have to adjust their own position or add additional auxiliary lighting equipment to ensure that the entire desk is illuminated, which undoubtedly increases the inconvenience and cost of use. Utility Model Content

[0004] The purpose of this invention is to overcome the problem that existing floor lamps lack a tilting adjustment function, which results in the inability to adjust the offset distance of the lighting area according to needs, and to provide a floor lamp with a tilting adjustment function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A floor lamp includes a lighting device, a lamp post, and a base. The lower end of the lamp post is connected to the base, and the upper end of the lamp post is rotatably connected to the lighting device via a rotating connection structure, allowing the lighting device to tilt relative to the lamp post around a horizontal axis, thereby adjusting the offset distance of the lighting area. The rotating connection structure includes a first adapter seat at the upper end of the lamp post, a second adapter seat inside the lighting device, and a rotating positioning structure. A first rotating shaft extending into the second adapter seat is fixedly installed on one side of the first adapter seat, and a positioning block is fixedly installed on the first rotating shaft. The second adapter seat has a rotating block that fits against the positioning block and is sleeved on the first rotating shaft. The rotating positioning structure is located between the rotating block and the positioning block to achieve rotational positioning between them. When the lighting device rotates relative to the base, the rotational positioning structure achieves the rotational positioning of the lighting device.

[0007] Compared to existing technologies, this utility model's floor lamp features a lighting device that is rotatably connected to the upper end of the lamp post via a rotating connection structure. This allows the lighting device to tilt relative to the lamp post around a horizontal axis, enabling users to adjust the lighting angle and the size of the projected illumination surface according to different positions on the desktop. This significantly overcomes the limitations of traditional floor lamps with fixed lighting directions. This design not only enhances the practicality of the lighting device but also significantly improves the user's lighting experience in various life scenarios. Users no longer need to adjust their position due to a fixed lighting device or purchase additional auxiliary lighting equipment, effectively reducing usage costs and inconvenience. It also meets diverse lighting needs.

[0008] Furthermore, the rotation positioning structure includes a plurality of positioning grooves arranged circumferentially on the outside of the positioning block and positioning protrusions on the rotating block. When the lighting device rotates relative to the positioning block, the positioning protrusions cooperate with any positioning groove to achieve rotation positioning of the lighting device. With this arrangement, the lighting device can be tilted step by step when the angle is adjusted, and the rotation positioning effect is good.

[0009] Furthermore, the rotation positioning structure includes a positioning protrusion on the positioning block and several positioning grooves arranged circumferentially on the outer side of the rotating block. When the lighting device rotates relative to the positioning block, the positioning protrusion cooperates with any positioning groove to achieve rotation positioning of the lighting device. With this arrangement, the lighting device can achieve step-by-step tilting when the angle is adjusted, resulting in good rotation positioning effect.

[0010] Furthermore, at least two sets of the plurality of positioning grooves are located on the positioning blocks in a rotationally symmetrical arrangement, and at least two sets of the positioning protrusions are located on the rotating blocks in a rotationally symmetrical arrangement; with this arrangement, the rotating positioning structure has two sets, which makes the rotational positioning stability of the lighting device better.

[0011] Furthermore, it also includes a first connecting pin, with a first threaded portion and a first pin head at each end. The middle part of the first connecting pin is the first rotating shaft, which is non-circular. The rotating block has a first circular hole in its middle that fits into the first rotating shaft, allowing the rotating block to rotate circumferentially relative to the first rotating shaft. The positioning block has a first fixing hole in its middle that matches the shape of the first rotating shaft, preventing the positioning block from rotating relative to the first rotating shaft. With this arrangement, the positioning block is kept in a limited stationary state, while the rotating block remains rotatable, ensuring a rotational positioning effect between the two.

[0012] Furthermore, the first threaded portion is provided with a first nut, a first positioning sleeve is provided between the rotating block and the first nail head, and a plurality of first washers are provided between the first nut and the positioning block. By locking the first nut, the positioning block and the rotating block are brought into contact. With this arrangement, the limiting effect between the plurality of first washers and the first positioning sleeve ensures that the rotating block and the positioning block are relatively close together.

[0013] Furthermore, two second adapter seats are provided, located on either side of the first adapter seat. The rotation positioning structure is located in one of the second adapter seats, and the other second adapter seat is provided with an elastic reset structure. The elastic reset structure includes a first connecting seat in the first adapter seat, a second connecting seat in the second adapter seat, a second rotating shaft connected to the first connecting seat, and a torsion spring. The second connecting seat is rotatably sleeved on the second rotating shaft, and the two torsion arms of the torsion spring are respectively connected to the first connecting seat and the second connecting seat. By providing an elastic reset structure, the user can operate the device more easily when tilting it back to the horizontal position.

[0014] Furthermore, it also includes a second connecting pin, with a second threaded portion and a second pin head at each end. The middle part of the second connecting pin is the second rotating shaft, which is non-circular. The middle part of the second connecting seat has a second circular hole that fits into the second rotating shaft, allowing the second connecting seat to rotate circumferentially relative to the second rotating shaft. The middle part of the first connecting seat has a second fixing hole that matches the shape of the second rotating shaft, preventing the first connecting seat from rotating relative to the second rotating shaft. With this arrangement, the first connecting seat is kept in a limited stationary state, while the second connecting seat remains rotatable, ensuring that the two can achieve relative rotation and drive the torsion spring.

[0015] Furthermore, the second threaded portion is provided with a second nut, the first connecting seat is limited to the inside of the second nail head, the torsion spring is provided between the first connecting seat and the second connecting seat, and a plurality of second washers are provided between the second nut and the second connecting seat. By locking the second nut, the first connecting seat and the second connecting seat are fixed on the second connecting nail. With this arrangement, the relative distance between the first connecting seat and the second connecting seat and the torsion spring is ensured by the limiting effect of the plurality of second washers and the second fixed nail.

[0016] Furthermore, the lighting device is rectangular, and its short side is rotatably connected to the upper end of the lamp post via a rotating connection structure. Attached Figure Description

Detailed Implementation

[0028] The specific embodiments of this utility model are described below with reference to the accompanying drawings. In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] The technical solution of this utility model is described below with reference to the accompanying drawings:

[0030] See Figures 1 to 10 The floor lamp of this utility model includes a lighting device 1, a lamp post 2, and a base 3. The lower end of the lamp post 2 is connected to the base 3, and the upper end of the lamp post 2 is rotatably connected to the lighting device 1 through a rotating connection structure, so that the lighting device 1 can swing relative to the lamp post 2 around a horizontal axis 401, thereby adjusting the offset distance of the lighting area of ​​the lighting device 1. The rotating connection structure includes a first adapter 5 at the upper end of the lamp post 2, a second adapter 6 inside the lighting device 1, and a rotating positioning structure 40. A first rotating shaft 49 extending into the second adapter 5 is fixedly provided on one side of the first adapter 5. A positioning block 61 is fixedly provided on the first rotating shaft 49. The second adapter 6 is provided with a rotating block 48 that is relatively close to the positioning block 61 and sleeved on the first rotating shaft 49. The rotating positioning structure 40 is provided between the rotating block 48 and the positioning block 61 to realize the rotational positioning between the two. When the lighting device 1 rotates relative to the lamp post, the rotational positioning of the lighting device 1 is realized through the action of the rotating positioning structure 40.

[0031] Compared with existing technologies, the floor lamp of this invention features a lighting device 1 that is rotatably connected to the upper end of the lamp post 2 via a rotating connection structure. This allows the lighting device 1 to tilt relative to the lamp post 2 around a horizontal axis 401, enabling users to adjust the illumination angle and the size of the projected surface of the lighting device 1 according to different positions on the desktop. This significantly overcomes the limitations of traditional floor lamps with fixed lighting directions. This design not only enhances the practicality of the lighting device 1 but also significantly improves the user's lighting experience in different life scenarios. Users no longer need to adjust their own position or purchase additional auxiliary lighting equipment due to the fixed lighting device 1, thus effectively reducing usage costs and inconvenience. It also meets diverse lighting needs.

[0032] See Figure 9 and Figure 10 The floor lamp of this invention features a lighting device 1 that can be tilted relative to the lamp post 2 around a horizontal axis 401. This allows the user to adjust the lighting angle and the size of the projected image on the illuminated surface according to different positions on the desktop. Specifically, it utilizes the principle that the farther the light projection from the desktop, the larger the projected image; conversely, the closer the light projection is to the desktop, the smaller the projected image. For example, when the user is using a small desktop, tilting the lighting device 1 to a position closer to the desktop allows the light to be projected onto the entire desktop surface (e.g., ...). Figure 9 (Effect) When the user is using a large desktop, by tilting the lighting device 1 to increase the distance between the lighting device 1 and the desktop, the angle of the illuminated surface of the lighting device 1 can be adjusted, and the light projection area of ​​the lighting device 1 can be increased, so that the light can be fully projected onto the entire desktop (e.g., Figure 10 Effect).

[0033] See Figures 1 to 6 In one embodiment, the rotation positioning structure 40 includes a plurality of positioning grooves 481 arranged circumferentially on the outside of the positioning block 61 and positioning protrusions 66 on the rotating block 48. When the lighting device 1 rotates relative to the positioning block 48, the positioning protrusions 66 cooperate with any positioning groove 481 to achieve rotation positioning of the lighting device 1. With this arrangement, the lighting device 1 can be tilted step by step when the angle is adjusted, and the rotation positioning effect is good.

[0034] In an alternative embodiment (not shown), the rotation positioning structure 40 includes a positioning protrusion 66 on the positioning block 61 and a plurality of positioning grooves 481 arranged circumferentially on the outer side of the rotating block 48. When the lighting device 1 rotates relative to the positioning block 48, the positioning protrusion 66 cooperates with any positioning groove 481 to achieve rotation positioning of the lighting device 1. With this arrangement, the lighting device 1 can achieve step-by-step tilting when the angle is adjusted, resulting in good rotation positioning effect.

[0035] See Figures 2 to 6 In one embodiment, at least two sets of the plurality of positioning grooves 481 are arranged in a rotationally symmetrical manner on the positioning block 61, and at least two sets of the positioning protrusions 66 are arranged in a rotationally symmetrical manner on the rotating block 48. With this arrangement, the rotating positioning structure 40 is provided with two sets, which makes the rotational positioning stability of the lighting device 1 better.

[0036] See Figures 2 to 6 In one embodiment, the device further includes a first connecting pin 4, with a first threaded portion 41 and a first pin head 42 at both ends. The middle part of the first connecting pin 4 is a first rotating shaft 49, which is non-circular. The rotating block 48 has a first circular hole 64 in its middle that engages with the first rotating shaft 49, allowing the rotating block 48 to rotate circumferentially relative to the first rotating shaft 49. The positioning block 61 has a first fixing hole 482 in its middle that matches the shape of the first rotating shaft 49, preventing the positioning block 61 from rotating relative to the first rotating shaft 49. This configuration effectively keeps the positioning block 61 in a limited stationary state while the rotating block 48 remains rotatable, ensuring a rotational positioning effect between the two.

[0037] See Figures 2 to 6 In one embodiment, the first threaded portion 41 is provided with a first nut 43, a first positioning sleeve 44 is provided between the rotating block 48 and the first nail head 42, and a plurality of first washers 45 are provided between the first nut 43 and the positioning block 61. By locking the first nut 43, the positioning block 61 and the rotating block 48 are brought into contact. With this arrangement, the limiting effect between the plurality of first washers 45 and the first positioning sleeve 44 ensures that the rotating block 48 and the positioning block 61 are relatively close together.

[0038] See Figures 2 to 6 In one embodiment, two second adapter seats 6 are spaced apart, located on both sides of the first adapter seat 5. The rotation positioning structure 40 is located in one of the second adapter seats 6, and the other second adapter seat 6 is provided with an elastic reset structure 8. The elastic reset structure 8 includes a first connecting seat 81 located in the first adapter seat 5, a second connecting seat 82 located in the second adapter seat 6, a second rotating shaft 83 connected to the first connecting seat 81, and a torsion spring 84. The second connecting seat 82 is rotatably sleeved on the second rotating shaft 83, and the two torsion arms of the torsion spring 84 are respectively connected to the first connecting seat 81 and the second connecting seat 82. By providing the elastic reset structure 8, the user can operate the lighting device 1 more easily when it is reset to a horizontal position.

[0039] See Figure 2 , Figure 7 and Figure 8 In one embodiment, a second connecting pin 85 is further included. The two ends of the second connecting pin 85 are respectively provided with a second threaded portion 851 and a pin head 852. The middle part of the second connecting pin 85 is a second rotating shaft 83. The second rotating shaft 83 is non-circular. The middle part of the second connecting seat 82 is provided with a second circular hole 88 that fits with the second rotating shaft 83, so that the second connecting seat 82 can rotate circumferentially relative to the second rotating shaft 83. The middle part of the first connecting seat 81 is provided with a second fixing hole 89 that matches the shape of the second rotating shaft 83, so that the first connecting seat 81 cannot rotate relative to the second rotating shaft 83. With this arrangement, the first connecting seat 81 is kept in a limited stationary state, and the second connecting seat 82 is kept rotatable, ensuring that the two can achieve relative rotation and drive the torsion spring 84.

[0040] See Figure 2 , Figure 7 and Figure 8 In one embodiment, the second threaded portion 851 is provided with a second nut 86, the first connecting seat 81 is limited inside the second nail head 852, the torsion spring 84 is disposed between the first connecting seat 81 and the second connecting seat 82, and a plurality of second washers 87 are provided between the second nut 86 and the second connecting seat 82. By locking the second nut 86, the first connecting seat 81 and the second connecting seat 82 are fixed on the second connecting nail 85. With this arrangement, the relative distance between the first connecting seat 81 and the second connecting seat 82 and the torsion spring 84 is ensured by the limiting effect of the plurality of second washers 87 and the second nail head 852.

[0041] See Figure 1 and Figure 2 In one embodiment, the lighting device 1 is rectangular, and the short side of the lighting device 1 is rotatably connected to the upper end of the lamp post 2 via a rotating connection structure.
