[Solution] A swivel mounting structure (200) is fitted onto the outside of a connector (100), and a ceiling lamp is connected to a mounting surface via the connector. The swivel mounting structure is provided with a boss that can rotate relative to the connector. The boss rotates relative to the connector to a first state to secure the swivel mounting structure to the connector. The boss rotates relative to the connector to a second state to press against the connector, thereby separating the swivel mounting structure from the connector. In this invention, a first rotational state corresponding to the attachment and fixation and a second rotational state corresponding to the removal and separation are set. When the swivel mounting structure and the connector are to be removed, the boss in the second rotational state is rotated until it presses against the connector, thereby separating the swivel mounting structure and the connector.

[0020] Those skilled in the art will understand that all terms (including technical and scientific terms) used herein have the same meaning as understood by those skilled in the art unless otherwise defined. It should also be understood that terms as defined in a general dictionary are understood to have a meaning consistent with the meaning in the context of the prior art, and are not to be construed in an idealized or overly formal sense unless specifically defined herein.

[0021] 1, the present disclosure provides a rotating mounting structure for a ceiling lamp, the rotating mounting structure 200 being detachably connected to an additional connector 100 (e.g., a conventional general-purpose lamp core base), one end of the connector 100 being detachably connected to an additional lamp core (not shown) (the specific manner of detachable connection may be referred to the prior art and will not be described in detail herein), and the other end of the connector 100 being fixedly connected (e.g., screwed) to a mounting surface (not shown, e.g., a ceiling), so that the ceiling lamp including the rotating mounting structure can be fixed to the mounting surface via the connector 100. As shown in FIG. 1, the rotating mounting structure 200 may be a lamp base, and the lamp base is detachably connected to an additional lamp shade 300 (the specific manner of detachable connection may be referred to the prior art and will not be described in detail herein) and forms a mounting chamber (not shown), which is used to accommodate at least a part of the connector 100. As shown in FIG. 1, the outer end of the mounting chamber of the connector 100 is provided with a threaded hole 150, which allows the connector 100 to be connected to a mounting surface by threading, and the inner end of the mounting chamber of the connector 100 can be detachably connected to an additional lamp core (not shown).

[0022] As shown in FIGS. 2 and 3 , the rotating mounting structure 200 is fitted to the outside of the connector 100, and the rotating mounting structure 200 is provided with bosses (including a first boss 210 and a second boss 220, which may be fixedly connected to the rotating mounting structure 200 so as to be integrally molded with the rotating mounting structure 200). The first boss 210 and the second boss 220 can simultaneously rotate relative to the connector 100 between a first position a1 and a second position a2 (corresponding to a first state) and between the second position a2 and a third position a3 (corresponding to a second state) (in the embodiment of the present disclosure, the c1 direction shown in FIG. 2 is the rotation direction from separation to locking), and the second position a2 is located between the first position a1 and the third position a3. In other words, when the first boss 210 and the second boss 220 simultaneously rotate between the first position a1 and the second position a2, they are both in the first state relative to the connector 100. When the first boss 210 and the second boss 220 simultaneously rotate between the second position a2 and the third position a3, they are in a second state relative to the connector 100. In this embodiment, the rotatable mounting structure 200 is rotatable between the first position a1 and the third position a3, which requires the rotatable mounting structure 200 to pass through the second position a2, relative to the connector 100, but is not rotatable between the first position a1 and the third position a3, which does not require the rotatable mounting structure 200 to pass through the second position a2, relative to the connector 100. When the rotatable mounting structure 200 rotates between the first position a1 and the second position a2, the rotatable mounting structure 200 and the connector 100 are fixed, i.e., cannot be removed or separated. When the rotatable mounting structure 200 rotates between the second position a2 and the third position a3, the bosses press against the connector 100, allowing the rotatable mounting structure 200 to be separated from the connector 100. Furthermore, in this embodiment, when the rotating mounting structure 200 is in the first position a1, the first boss 210 and the second boss 220 abut against the connector 100. When the rotating mounting structure 200 is in the second position a2, the rotating mounting structure 200 is fixed to the connector 100. When the rotating mounting structure 200 is in the third position a3, the first boss 210 and the second boss 220 continue to press against the connector 100, allowing the rotating mounting structure 200 to be separated from the connector 100. The second position a2 in this embodiment is a non-separation position. Furthermore, in some embodiments, the rotating mounting structure 200 can be separated from the connector 100 when the rotating mounting structure 200 is in the second position a2.

[0023] The rotatable mounting structure for a ceiling lamp according to the present disclosure is configured to be fitted onto the outside of the additional connector so as to be rotatable relative to the connector, and is provided with a boss that is set to a first rotation state corresponding to mounting fixation and a second rotation state corresponding to removal and separation. When removing the rotatable mounting structure and the connector, the boss in the second rotation state is rotated until it presses the connector, thereby achieving separation of the rotatable mounting structure and the connector, thereby eliminating the need for additional sliding means, resulting in a simple structure and quick removal. Therefore, the rotatable mounting structure for a ceiling lamp according to the present disclosure solves the technical problem of related art, which requires additional sliding means to be provided on the ceiling lamp to remove the lamp, resulting in a complex structure and a time-consuming removal process.

[0024] 1, a through-hole 230 is formed in the middle of the rotatable mounting structure 200, and the rotatable mounting structure 200 is fitted onto the connector 100 through the through-hole 230. That is, the inner end of the connector 100 extends into the mounting chamber through the through-hole 230. As shown in FIGS. 2, 3, 4, and 5, the through-hole 230 includes a bottom surface BS and a side surface SS. A first boss 210 (protruding from the side surface SS) is provided on one side of the side surface SS, and a second boss 220 (protruding from the side surface SS) is provided on the other side opposite the side surface SS. The first boss 210 and the second boss 220 may be configured as mirror images. As shown in FIG. 3, the first boss 210 includes a first pressing surface 71 and a first contact surface 81 that are connected to each other, and the first pressing surface 71 intersects with the first contact surface 81, and the second boss 220 includes a second pressing surface 72 and a second contact surface 82 that are connected to each other, and the second pressing surface 72 intersects with the second contact surface 82.

[0025] As shown in FIGS. 2 and 3 , a first elastic protrusion 110 (protruding from the outer surface of the cylindrical end without the application of an external force) is provided on one side of the mounting chamber inner end of the connector 100 (which may be, but is not limited to, the cylindrical end shown in FIG. 1 ). The first elastic protrusion 110 can contract into the interior of the connector 100 when an external force is applied, and can rebound to protrude from the connector 100 when the external force is removed. The specific principles of the contraction and rebound of the first elastic protrusion 110 can be found in the prior art and will not be described in detail here. As shown in FIGS. 2 and 3 , a second elastic protrusion 120 (protruding from the outer surface of the cylindrical end) is provided on the other side opposite the mounting chamber inner end of the connector 100. The second elastic protrusion 120 can contract into the interior of the connector 100 when an external force is applied, and can rebound to protrude from the connector 100 when the external force is removed. The specific principles of the contraction and rebound of the second elastic protrusion 120 can be found in the prior art and will not be described in detail here. 7, the first elastic protrusion 110 includes a first bottom surface 111, a first force receiving surface 31, and a first limiting surface 41, which are connected to each other, and the first bottom surface 111, the first force receiving surface 31, and the first limiting surface 41 intersect with each other two by two, and the first limiting surface 41 is closer to the second boss 220 than the first force receiving surface 31, and the second contact surface 82 is closer to the first limiting surface 41 than the second pressing surface 72. As shown in FIG. 6, the second elastic protrusion 120 includes a second bottom surface 121, a second force receiving surface 32, and a second limiting surface 42 that are connected to each other, and the second bottom surface 121, the second force receiving surface 32, and the second limiting surface 42 intersect two by two, the second limiting surface 42 is closer to the first boss 210 than the second force receiving surface 32, and the first contact surface 81 is closer to the second limiting surface 42 than the first pressing surface 71.

[0026] When the rotating mounting structure 200 is in the first position a1, the bottom surface BS of the through hole 230 abuts against the first bottom surface 111 and also abuts against the second bottom surface 121, thereby fixing the rotating mounting structure 200 and the connector 100, and at this time, the first elastic protrusion 110 and the second elastic protrusion 120 are both in a protruding state. The first contact surface 81 of the first boss 210 abuts against the second limiting surface 42 of the second elastic protrusion 120, and the second limiting surface 42 limits the movement of the second elastic protrusion 120 of the first boss 210 toward the second force receiving surface 32 (i.e., limits the movement of the first boss 210 toward the third position a3, which does not need to pass through the second position a2), and the second contact surface 82 of the second boss 220 abuts against the first limiting surface 41 of the first elastic protrusion 110, and the first limiting surface 41 limits the movement of the second boss 220 toward the first force receiving surface 31 of the first elastic protrusion 110 (i.e., limits the movement of the second boss 220 to the first position a1, which needs to pass through the second position a2).

[0027] When the rotatable mounting structure 200 moves away from the first position a1 and rotates between the first position a1 and the second position a2, the bottom surface BS of the through hole 230 abuts against the first bottom surface 111 and the second bottom surface 121, thereby fixing the rotatable mounting structure 200 and the connector 100. At this time, the first elastic protrusion 110 and the second elastic protrusion 120 are both in a protruding state. Then, the first contact surface 81 of the first boss 210 is no longer in contact with the second limiting surface 42 of the second elastic protrusion 120, and the second contact surface 82 of the second boss 220 is no longer in contact with the first limiting surface 41 of the first elastic protrusion 110.

[0028] When the swivel mounting structure 200 is in the second position a2, the first pressing surface 71 of the first boss 210 begins to contact the first elastic protrusion 110, and simultaneously the second pressing surface 72 of the second boss 220 begins to contact the second elastic protrusion 120. At this time, the bottom surface BS of the through hole 230 abuts against the first bottom surface 111 and also abuts against the second bottom surface 121, thereby fixing the swivel mounting structure 200 and the connector 100, and simultaneously the first elastic protrusion 110 and the second elastic protrusion 120 are both in a protruding state.

[0029] When the rotating mounting structure 200 moves away from the second position a2 and rotates between the second position a2 and the third position a3 (including when the rotating mounting structure 200 is in the third position a3), the first pressing surface 71 of the first boss 210 abuts against the first force receiving surface 31 of the first elastic protrusion 110 and presses the first force receiving surface 31, causing the first elastic protrusion 110 to enter a contracted state, and at the same time, the second pressing surface 72 of the second boss 220 abuts against the second force receiving surface 32 of the second elastic protrusion 120 and presses the second force receiving surface 32, causing the second elastic protrusion 120 to enter a contracted state. At this time, the bottom surface BS of the through hole 230 is no longer in contact with the first bottom surface 111, and is no longer in contact with the second bottom surface 121, thereby allowing the connector 100 to be ejected from the mounting chamber through the through hole 230, thereby realizing removal between the rotating mounting structure 200 and the connector 100. This removal is smooth and quick, and the structure is simpler than that of a ceiling lamp equipped with a sliding means.

[0030] When mounting a ceiling lamp on a mounting surface, the user first screws the connector into the mounting surface through the connector's screw hole, and then inserts the swivel mounting structure into the connector through the through-hole of the swivel mounting structure. At this time, the first boss presses the first elastic protrusion, causing it to contract, and the second boss presses the second elastic protrusion, causing it to contract, so that the swivel mounting structure and connector are between the second and third positions. The swivel mounting structure is then rotated (perhaps counterclockwise) to move the swivel mounting structure and connector between the first and second positions. At this time, the swivel mounting structure and connector are fixed and inseparable. Finally, an additional lamp core is connected to the connector, and then an additional lampshade is connected to the swivel mounting structure to complete the ceiling lamp installation.

[0031] When it is necessary to remove the ceiling lamp from the mounting surface, the user rotates the mounting member (may be rotated clockwise) to move the rotatable mounting structure and the connector between the second position and the third position, thereby removing the rotatable mounting structure and the connector from the mounting surface to complete removal of the ceiling lamp. After this, the user removes the lampshade from the rotatable mounting structure and then removes the lamp core from the connector.

[0032] 4 , the first pressing surface 71 includes a first inclined surface 711 and a second inclined surface 712 that are connected to each other and have different degrees of inclination. The first inclined surface 711 is located between the first contact surface 81 and the second inclined surface 712, and intersects with the first contact surface 81 and the second inclined surface 712. The first inclined surface 711 presses the first force-receiving surface 31 when the rotatable mounting structure 200 rotates between the second position a2 and the third position a3, prevents the corner between the first contact surface 81 and the first pressing surface 71 from damaging the surface of the first elastic protrusion 110, and ensures smooth rotation of the rotatable mounting structure 200.

[0033] 5 , the second pressing surface 72 includes a third inclined surface 721 and a fourth inclined surface 722 that are connected to each other and have different degrees of inclination. The third inclined surface 721 is located between the second contact surface 82 and the fourth inclined surface 722 and intersects with the second contact surface 82 and the fourth inclined surface 722. The third inclined surface 721 presses the second force-receiving surface 32 when the rotatable mounting structure 200 rotates between the second position a2 and the third position a3, preventing the corner between the second contact surface 82 and the second pressing surface 72 from damaging the surface of the second elastic protrusion 120 and ensuring smooth rotation of the rotatable mounting structure 200.

[0034] 2 and 3 , when the rotatable mounting structure 200 rotates between a first position a1 and a second position a2 relative to the connector 100, the rotatable mounting structure 200 can rotate between the first position a1 and a fourth position a4 and between the fourth position a4 and the second position a2 relative to the connector 100. The fourth position a4 is between the first position a1 and the second position a2, and the second position a2 is between the fourth position a4 and a third position a3. As shown in FIGS. 4 and 5 , the bottom surface BS of the through hole 230 includes a non-threaded segment NT and a threaded segment, and the threaded segment includes a first threaded segment T1 corresponding to (close to) the first boss 210 and a second threaded segment T2 corresponding to (close to) the second boss 220.

[0035] When the rotating mounting structure 200 is in the first position a1, the entire surface of the first screw segment T1 abuts against the second bottom surface 121 of the second elastic protrusion 120, and at the same time, the entire surface of the second screw segment T2 abuts against the first bottom surface 111 of the first elastic protrusion 110, locking the rotating mounting structure 200 and the connector 100 and preventing them from coming off.

[0036] When the rotating mounting structure 200 moves away from the first position a1 and rotates between the first position a1 and the fourth position a4, at least a portion of the surface of the first screw segment T1 abuts against the second bottom surface 121 of the second elastic protrusion 120, and at least a portion of the surface of the second screw segment T2 abuts against the first bottom surface 111 of the first elastic protrusion 110. At the same time, at least a portion of the first inclined surface 711 and at least a portion of the third inclined surface 721 abut against the connector 100, thereby locking the rotating mounting structure 200 and the connector 100 and preventing them from falling off.

[0037] When the rotary mounting structure 200 is in the fourth position a4, the end of the first screw segment T1 remote from the first contact surface 81 is located on the second limiting surface 42, and the end of the first screw segment T1 close to the first contact surface 81 is located between the second limiting surface 42 and the first contact surface 81, and the end of the second screw segment T2 remote from the second contact surface 82 is located on the first limiting surface 41, and the end of the second screw segment T2 close to the second contact surface 82 is located between the first limiting surface 41 and the second contact surface 82. At this time, the surface of the first screw segment T1 is no longer in contact with the second bottom surface 121 of the second elastic protrusion 120, and at the same time, the surface of the second screw segment T2 is no longer in contact with the first bottom surface 111 of the first elastic protrusion 110.

[0038] In the above embodiment of the present disclosure, by providing a fourth rotation position corresponding to the screw segment between the first rotation position and the second rotation position, the friction force between the screw segment and the elastic protrusion can strengthen the fixation between the rotary mounting structure and the connector, effectively preventing the two from falling off.

[0039] 4, in some embodiments of this example, the end of the first screw segment T1 away from the first contact surface 81 gradually extends away from the bottom surface BS of the through hole 230 to the end of the first screw segment T1 closer to the first contact surface 81. That is, the height between the end of the first screw segment T1 closer to the first contact surface 81 and the bottom surface BS of the through hole 230 is greater than the height between the end of the first screw segment T1 away from the first contact surface 81 and the bottom surface BS, thereby effectively preventing the rotatable mounting structure 200 from moving autonomously from the first position a1 to the fourth position a4 after the mounting between the ceiling lamp and the mounting surface is completed, thereby further strengthening the fixation between the rotatable mounting structure and the connector.

[0040] 5 , the end of the second screw segment T2 away from the second contact surface 82 gradually extends away from the bottom surface BS of the through hole 230 to the end of the second screw segment T2 closer to the second contact surface 82. That is, the height between the end of the second screw segment T2 closer to the second contact surface 82 and the bottom surface BS of the through hole 230 is greater than the height between the end of the second screw segment T2 away from the second contact surface 82 and the bottom surface BS, thereby effectively preventing the rotatable mounting structure 200 from moving autonomously from the first position a1 to the fourth position a4 after the mounting between the ceiling lamp and the mounting surface is completed, thereby further strengthening the fixation between the rotatable mounting structure and the connector.

[0041] In this embodiment, when the first boss 210 and the second boss 220 simultaneously rotate between the fourth position a4 and the second position a2, the first inclined surface 711 and the third inclined surface 721 are out of contact with the connector 100, thereby reducing rotational resistance and facilitating removal. At a1-a4-a2, the first boss 210 and the second boss 220 transition from a locking to a loosened state relative to the connector 100, and at a2-a4-a1, the first boss 210 and the second boss 220 transition from a loosened to a locking state relative to the connector 100. Furthermore, in the embodiment of the present disclosure, the rotational direction (a2-a4-a1) required for the rotatable mounting structure 200 to transition from a loosened state to a locking state relative to the connector 100 is clockwise (direction c1 shown in FIG. 2 ). If the rotation direction (a2-a4-a1) required for the rotational mounting structure 200 to transition from the loosened state to the locking state relative to the connector 100 is counterclockwise, refer to FIG. 8 for a schematic diagram of another structure of the rotational mounting structure 200. The direction c2 shown in FIG. 8 is the rotation direction (counterclockwise) from separation to locking. The rotational mounting structure shown in FIG. 8 is a mirror image of the rotational mounting structure shown in FIG. 2, and both fall within the scope of protection of the present disclosure.

[0042] In addition to the rotary mounting structure for a ceiling lamp according to the present disclosure, the present disclosure further provides a ceiling lamp including the rotary mounting structure described above, a connector, and an additional lamp core. The connector has a screw hole that is screwed and fixed to a mounting surface, and the lamp core is detachably connected to the connector (the specific connection manner can be referred to in the prior art and will not be described in detail here), so that the installation and removal operations of the ceiling lamp and the rotary mounting structure can be completed quickly and easily.

[0043] In summary, the present disclosure provides a rotatable mounting structure for a ceiling lamp and a ceiling lamp, wherein the rotatable mounting structure is fitted onto the outside of a connector, and the ceiling lamp is connected to a mounting surface via the connector. The rotatable mounting structure is provided with a boss that is rotatable relative to the connector. The boss rotates relative to the connector to a first state to secure the rotatable mounting structure to the connector. The boss rotates relative to the connector to a second state to press against the connector, thereby separating the rotatable mounting structure from the connector. In the present disclosure, the rotatable mounting structure is configured to be fitted onto the outside of an additional connector so as to be rotatable relative to the connector, and the boss is provided with a first rotational state corresponding to the mounting and fixing, and a second rotational state corresponding to the removal and separation. When the rotatable mounting structure and the connector are to be removed, the boss is rotated in the second rotational state until it presses against the connector, thereby separating the rotatable mounting structure and the connector. This eliminates the need for an additional sliding means, resulting in a simple structure and quick removal.
