Description

Technical Field

[0001] The utility model belongs to the technical field of lighting fixtures, and in particular relates to a rotating shaft for a combined lamp panel and a lamp panel. Background Art

[0002] Table lamps are household appliances used for lighting in people's daily life. They usually include reading table lamps, decorative table lamps, study table lamps and portable table lamps. In the existing usage scenarios of table lamps, except for decorative table lamps, the structures of other types of table lamps need to consider issues such as luminous brightness and lighting range, so as to protect the user's eyes and increase the lighting area.

[0003] As people's living conditions gradually improve, indoor lamps in every household basically meet conventional lighting needs. Generally, table lamps are only used for decoration, or for reading and studying on desks. As an existing learning tool, table lamps themselves are awkward to use. During regular reading and learning, a single table lamp structure often cannot meet the lighting needs of users. The lighting area of ​​a single table lamp is often limited, and it can only illuminate part of the area, which can easily create a sense of claustrophobia. In order to ensure that users have a larger field of vision, the surrounding environment needs to be lit up. Users usually turn on the indoor lights and then turn on the table lamp at the same time to make up for the problem of insufficient light source in the desktop environment.

[0004] In order to solve the problem that a single desk lamp cannot fully illuminate the surrounding environment, existing products set two lamp surfaces on a single desk lamp, and increase the illuminated area of ​​the desk lamp by emitting light from the two lamp surfaces together. However, for desk lamps with multiple lamp surfaces, the light is often emitted on the same side, and the light source is relatively concentrated. Although some desk lamps have an angle adjustment function, they often focus the light source to increase the brightness, but cannot truly solve the problem of illuminating the surrounding environment together.

[0028] In general, compared with the prior art, the above technical solutions conceived by the utility model have the following beneficial effects:

[0029] (1) The rotating shaft for the combined lamp panel of the utility model is connected in series through a first connecting ring and a second connecting ring which are coaxially arranged side by side and a rotating shaft, so that the first connecting ring and the second connecting ring can rotate relative to each other along the rotating shaft to drive the first fixing part and the second fixing part connected thereto to rotate relative to each other, wherein the first fixing part is connected to the lamp panel through a first connecting port, and the second fixing part is connected to the lamp panel through a second connecting port; when the two lamp panels are driven to rotate by the first fixing part and the second fixing part, the two lamp panels are correspondingly flipped so that the corresponding light-emitting surfaces on the lamp panels are turned, thereby completing the illumination process of a conventional table lamp on a single surface. At the same time, the flipping design enables the two lamp panels to be combined to form a spherical light source with one up and one down, which can illuminate the entire surrounding environment.

[0030] (2) The rotating shaft for the combined lamp panel of the utility model has a damping surface arranged in the first connecting ring and a fitting surface arranged on the second rotating part. The friction between the damping surface and the fitting surface enables the first connecting ring and the second connecting ring to have a certain friction force when they rotate relative to each other, thereby allowing the lamp panel connected to the first fixing part and the second fixing part to stay at a set angle, so that the lamp panel connected to the rotating shaft for the combined lamp panel can be combined to form a variety of light-emitting modes; at the same time, the present application connects the first rotating part and the second rotating part by screws, and uses the screws to tighten to adjust the friction force between the damping surface and the fitting surface, thereby facilitating the angle adjustment of the lamp panel and facilitating the adjustment of the lamp panel to a set angle.

[0031] (3) The rotating shaft of the combined lamp panel of the utility model changes the wall surface where the first rotating part and the second connecting ring meet so that the two rotate synchronously; and a limit strip and a notch are provided on the wall surface where the first connecting ring and the second rotating part meet. By matching the limit strip with different notches, the first rotating part and the second connecting ring are locked at different angles, and the first connecting ring and the second connecting ring are locked at different angles, so that the two lamp panel structures connected thereto can be stably locked at different angles, thereby ensuring the stable use of the lamp panel.

[0032] (4) The rotating shaft for the combined lamp panel of the utility model adjusts the notch size of the outer peripheral wall of the second rotating part so that the first connecting ring and the second connecting ring are locked at the first notch, and the first connecting ring and the second connecting ring have a certain movable space at the second notch, so that the lamp panels connected to the two are locked when stacked on each other, ensuring stable lighting of the two lamp panels; when arranged side by side, they have a certain movable space, ensuring that the lighting brightness and angle of the lamp panels are adjustable, which is convenient for the use of the combined lamp panel in various scenarios.

[0047] Example:

[0048] See also Figures 1 to 7The rotating shaft for the combined lamp panel in the embodiment of the utility model includes a first connecting portion and a second connecting portion, and the first connecting portion and the second connecting portion are arranged to rotate with each other; the first connecting portion includes a first connecting ring 1, and the side wall of the first connecting ring 1 is radially connected to a first fixing portion 2; the second connecting portion includes a second connecting ring 3, and the side wall of the second connecting ring 3 is radially connected to a second fixing portion 4; the first connecting ring 1 and the second connecting ring 3 are coaxially arranged side by side along a first direction, and a rotating shaft is passed between the first connecting ring 1 and the second connecting ring 3; at the same time, the first fixing portion 2 and the second fixing portion 4 are arranged side by side along a second direction, and the above-mentioned first direction is perpendicular to the second direction; further, a first connecting port 14 is opened on one side of the first fixing portion 2, and a second connecting port is opened on one side of the second fixing portion 4, and the first connecting port 14 and the second connecting port are arranged away from each other.

[0049] Specifically, the rotating shaft for the combined lamp panel in the present application is connected in series through a first connecting ring 1 and a second connecting ring 3 which are coaxially arranged side by side, and then through a rotating shaft, so that the first connecting ring 1 and the second connecting ring 3 can rotate relative to each other along the rotating shaft to drive the first fixing part 2 and the second fixing part 4 connected thereto to rotate relative to each other, wherein the first fixing part 2 is connected to the lamp panel through a first connecting port 14, and the second fixing part 4 is connected to the lamp panel through a second connecting port; when the two lamp panels are driven to rotate by the first fixing part 2 and the second fixing part 4, the two lamp panels are flipped accordingly, so that the corresponding light-emitting surfaces on the lamp panels are turned, which completes the illumination process of a conventional table lamp on a single side, and at the same time, the flipping design allows the two lamp panels to be combined to form a spherical light source with one up and one down, which can illuminate the entire surrounding environment, so that the lamp panel structure formed by the rotating shaft combination can not only meet the user's daily learning and reading needs, but also illuminate the entire surrounding environment, so that the user will not feel claustrophobic, thereby increasing the scope of application of the table lamp.

[0050] Furthermore, the first direction in the present application is the axial direction of the first connecting ring 1 and the second connecting ring 3; the second direction is one of the directions perpendicular to the radial direction of the first connecting ring 1 and the second connecting ring 3; and the third direction is a direction perpendicular to the plane where the first direction and the second direction are located.

[0051] Further, as a preferred embodiment of the present utility model, the rotating shaft in the present application includes a first rotating part 5 and a second rotating part 6 arranged axially along the first connecting ring 1, the first rotating part 5 is coaxially sleeved in the second connecting ring 3, the second rotating part 6 is coaxially sleeved in the first connecting ring 1, and the first rotating part 5 and the second rotating part 6 are detachably connected along the axial direction. When the conventional first connecting ring 1, the second connecting ring 3 and the rotating shaft structure are adopted, the first connecting ring 1 and the second connecting ring 3 cannot be relatively locked, and both can rotate relative to the rotating shaft, so that the lamp panel structure connected to the first fixing part 2 and the second fixing part 4 cannot be locked to the set position, and the two lamp panels cannot be combined to form a variety of light-emitting forms arranged in the same direction or oppositely. Therefore, the present application corresponds to setting the rotating shaft as a combination of the first rotating part 5 and the second rotating part 6, so that the first rotating part 5 and the second rotating part 6 can be designed separately, and the two lamp panels connected thereto are positioned at the set position and angle by the cooperation of the two rotating parts with the first connecting ring 1 and the second connecting ring 3 respectively.

[0052] Furthermore, in the present application, a damping surface 7 is provided radially inside the first connecting ring 1, the first rotating part 5 and the second rotating part 6 are arranged on both sides of the damping surface 7, and the damping surface 7 is provided with a first through hole along the axial direction of the first connecting ring 1; the second rotating part 6 is provided with a fitting surface 8 on the side facing the damping surface 7, and the fitting surface 8 is in contact with the damping surface 7, so that when the first connecting ring 1 and the second connecting ring 3 rotate relative to each other, relative friction is generated between the second rotating part 6 and the first connecting ring 1, thereby allowing the first connecting ring 1 and the second connecting ring 3 to stop at any angle, so that the lamp panel connected to the first fixing part 2 and the second fixing part 4 is fixed at any angle. At the same time, a second through hole is provided along the axial direction of the first connecting ring 1 on the fitting surface 8, and screws 9 are inserted into the first through hole and the second through hole, and the screws 9 connect the first rotating part 5 with the second rotating part 6. In the present application, a threaded hole is correspondingly provided on the first rotating part 5, and the screws 9 pass through the first through hole and the second through hole, thereby connecting the first rotating part 5 and the second rotating part 6 as a whole. The threaded connection makes the damping between the damping surface 7 and the fitting surface 8 adjustable so that the rotating shaft can adapt to lamp panels of different sizes, ensuring that the lamp panel can stay in any position while increasing the convenience of adjusting the lamp panel and avoiding difficulty in adjustment caused by excessive damping.

[0053] Further, as a preferred embodiment of the utility model, the first rotating part 5 in the present application is a columnar structure along the axial direction, and the first rotating part 5 has at least two planes in the circumference, and the inner circumferential wall surface of the second connecting ring 3 is mutually engaged with the outer circumferential wall surface of the first rotating part 5. As mentioned above, the present application requires that the first connecting ring 1 and the second connecting ring 3 can rotate relative to each other, and at the same time, the two can be stopped at any angle, wherein the first connecting ring 1 and the second rotating part 6 realize damping rotation through the cooperation of the damping surface 7 and the fitting surface 8. If the second connecting ring 3 and the first rotating part 5 can rotate arbitrarily, the first connecting ring 1 and the second connecting ring 3 cannot stop at any angle. Based on this, the present application sets at least two plane structures on the outer periphery of the first rotating part 5, and the planes are offset against the planes of the inner periphery of the second connecting ring 3 to avoid the relative rotation of the first rotating part 5 and the second connecting ring 3. Optionally, the outer periphery of the first rotating part 5 in the present application can be set to a polygon, a thread, a bevel gear structure, etc., as long as other forms that ensure the relative locking of the first rotating part 5 and the second connecting ring 3 are all acceptable.

[0054] Furthermore, the inner circumferential wall surface of the first connecting ring 1 is provided with at least one limiting strip 10, and the limiting strip 10 protrudes from the inner wall of the first connecting ring 1, and the outer circumferential wall surface of the second rotating part 6 is provided with at least two notches 11 matching the limiting strip 10, and the two notches 11 are distributed in different directions of the outer circumference of the second rotating part 6. Although the above-mentioned damping rotation form can keep the first connecting ring 1 and the second connecting ring 3 at different angles, its stability is poor. During the long-term use of the lamp panel, it will cause relative wear between the damping surface 7 and the fitting surface 8, and finally make the lamp panel unable to be locked at the set angle. Based on this, the present application corresponds to setting a limiting strip 10 on the inner circumferential wall surface of the first connecting ring 1, and corresponding to setting a notch 11 on the outer circumferential wall surface of the second rotating part 6. When the limiting strip 10 is stuck in the notch 11, the first connecting ring 1 and the second connecting ring 3 are relatively locked, thereby fixing the two lamp panels at different angles. When the light-emitting form of the lamp panel needs to be changed, the first connecting ring 1 and the second connecting ring 3 rotate relative to each other, and the limiting strip 10 is disengaged from one of the notches 11 and then falls into the other notch 11, locking the first connecting ring 1 and the second connecting ring 3 at another angle, thereby realizing the locking of the lamp panels at different angles. Preferably, the two notches 11 are distributed at two positions in the same radial direction, so that a single limiting strip 10 can match the two notches 11 respectively, thereby realizing the locking of the two connecting rings at different angles.

[0055] Of course, in addition to the above-mentioned matching form of a single limiting strip 10 and two notches 11, a plurality of limiting strips 10 and a plurality of notches 11 may also be matched to achieve locking of the two lamp panels at different angles.

[0056] Further, as an optional embodiment of the utility model, the outer peripheral wall surface of the second rotating part 6 in the present application has a first notch 11 and a second notch 11, and the limit strip 10 can match the first notch 11 and the second notch 11 respectively. In addition, the opening width of the first notch 11 is the same as the width of the limit strip 10, and the opening width of the second notch 11 is not less than the width of the limit strip 10. When the direction and angle of the two lamp panels are limited by the rotating shaft connection, when the two lamp panels are stacked on each other, the two lamp panels are in a stable position. At this time, the two lamp panels do not need to have space for movement. The two lamp panels can be locked by the limitation of the first notch 11 and the limit strip 10, which is convenient for the collection and placement of the lamp panels. When the first connecting ring 1 and the second connecting ring 3 rotate 180° relative to each other, the two lamp panels change from being stacked on each other to being arranged side by side. At this time, the limit strip 10 falls into the second notch 11. In actual use, when the two lamp panels are in a straight state, the user needs to adjust the angle of the lamp panel appropriately according to the actual situation. If the second notch 11 completely locks the limit strip 10, it is not convenient to adjust the angle of the lamp panel. Therefore, the width of the second notch 11 can be appropriately adjusted so that the second notch 11 is larger than the width of the limit strip 10, and the limit strip 10 can move slightly in the second notch 11. Then, the damping surface 7 and the fitting surface 8 cooperate to lock the angle of the lamp panel, so as to achieve a small adjustment of the lamp panel in a straight state.

[0057] Furthermore, the second connection part of the present application also includes a third connection ring 12 arranged side by side with the second connection ring 3, and the first connection ring 1 is clamped between the second connection ring 3 and the third connection ring 12, and the second connection ring 3 and the third connection ring 12 are connected as a whole through the second fixing part 4. When the first connection ring 1 and the second connection ring 3 are used to rotate relative to each other, the two cannot form a constraint, so that the relative rotation of the two is not stable enough. Based on this, the present application sets the third connection ring 12, and the first connection ring 1 is restricted by the second connection ring 3 and the third connection ring 12, so that the first connection ring 1 rotates along the set direction to ensure the stable rotation and matching of the lamp panel, maintain the overall beauty of the lamp, and avoid wear caused by long-term mismatch of various structural parts, etc., to ensure the service life of the lamp. At the same time, the clamping form of the second connection ring 3 and the third connection ring 12 can ensure that the first connection ring 1 does not deviate during the rotation process, ensure the friction between the damping surface 7 and the fitting surface 8, so that the two lamp panels can stay at the set angle, which is convenient for the use of the lamp.

[0058] Further preferably, in the present application, the second connecting ring 3 and the third connecting ring 12 are both provided with a cover 13 on the side facing away from the first connecting ring 1, and the cover 13 closes both ends of the second connecting ring 3 and the third connecting ring 12. The rotating shaft is arranged in the cylindrical space formed by the first connecting ring 1, the second connecting ring 3 and the third connecting ring 12. In order to avoid the rotating shaft being exposed to affect the appearance and to prevent external dust from entering the cylindrical space, the covers 13 are arranged at both ends of the second connecting ring 3 and the third connecting ring 12 to ensure the stable use of the rotating shaft in the cylindrical space.

[0059] Further preferably, in the present application, the first connection port 14 opens along the second direction, and at least one positioning column 15 is provided in the first connection port 14, and the positioning column 15 is provided with a threaded hole in the axial direction. A stable connection cannot be formed only by matching the opening and the protrusion. In order to prevent the lamp panel from being separated from the first fixing part 2, the present application sets a positioning column 15 on the first fixing part 2 and provides a threaded hole. When the lamp panel is matched with the first fixing part 2, the lamp panel and the first fixing part 2 are fixed by screws 9 to ensure a stable connection between the two. Optionally, two positioning columns 15 are arranged side by side in the first connection port 14, and threaded holes are provided in the two positioning columns 15, and the lamp panel and the first fixing part 2 are fixed by screws 9 to further enhance the stability of the connection between the lamp panel and the first fixing part 2.

[0060] Furthermore, since the first fixing part 2 and the second fixing part 4 in the present application are respectively used to connect two lamp panels, the structures of the first fixing part 2 and the second fixing part 4 in the present application are the same to achieve a stable connection between the fixing part and the lamp panel.

[0061] Furthermore, in the present application, the side wall of the first fixing part 2 is provided with a limiting groove and a limiting protrusion along the third direction, and the limiting groove and the limiting protrusion are arranged side by side. Since the first connecting ring 1 needs to drive the lamp panel to swing together during the rotation process, in order to avoid the gravity of the lamp panel being concentrated on the first connecting port 14 and to avoid stress concentration causing damage to the first fixing part 2, the present application corresponds to setting a limiting groove and a limiting protrusion on the side wall of the first fixing part 2, and the limiting groove and the limiting protrusion are matched with the lamp panel to increase the connection stability between the lamp panel and the first fixing part 2, and distribute the gravity of the lamp panel to a longer moment to avoid the problem of stress concentration.

[0062] Further, based on the rotation axis for combining lamp panels in the present application, the present application also includes a lamp panel, which includes a first lamp panel 16 and a second lamp panel 17, wherein the first lamp panel 16 has a first light-emitting surface, and the second lamp panel 17 has a second light-emitting surface. The first lamp panel 16 and the second lamp panel 17 are arranged side by side, and the first light-emitting surface and the second light-emitting surface are arranged away from each other. The above-mentioned rotation axis for combining lamp panels is arranged between the first lamp panel 16 and the second lamp panel 17, and the first lamp panel 16 is connected to the second fixing portion 4, and the second lamp panel 17 is connected to the first fixing portion 2. The first lamp panel 16 and the second lamp panel 17 are connected by the rotation axis to form two lamp panel structures that are arranged away from each other. When the first lamp panel 16 and the second lamp panel 17 are stacked on each other, the two emit light to form a spherical light source to illuminate the surrounding environment; when the second lamp panel 17 rotates 180°, the two light-emitting surfaces face downward at the same time, forming two light sources arranged side by side, so as to increase the illuminated area and brightness of the lamp panel on the desktop.

[0063] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
