While existing lighting fixtures can achieve lamp head rotation, their internal structures are relatively complex, and the positioning effect during lamp head rotation is poor.

[0003] Therefore, existing technologies suffer from poor performance of rotatable lamps.

[0007] In a preferred embodiment of this application, when at least one of the first mating structure and the second mating structure is at least two and the rotating component rotates to different positions, the second mating structure mates with different first mating structures or the first mating structure mates with different second mating structures, so that the rotating component remains in different positions.

[0009] In a preferred embodiment of this application, when the follower rotates with the rotating body, the follower moves relative to the positioning member in a direction that is closer to or farther away from the positioning member in the axial direction of the rotating body.

[0010] In a preferred embodiment of this application, one of the first mating structure and the second mating structure is a positioning groove and the other is a positioning protrusion. When the first mating structure and the second mating structure are mated together, at least a portion of the positioning protrusion is located inside the positioning groove.

[0011] In a preferred embodiment of this application, the rotating device further includes a deformable member, which is sleeved on the rotating body and disposed on the side of the positioning member away from the follower member.

[0012] In a preferred embodiment of this application, the deformable member includes at least one of a spring and a silicone pad; or the rotating device further includes a washer and a retaining spring respectively sleeved on the rotating body, one end of the deformable member abutting against the side of the positioning member away from the follower, the other end of the deformable member abutting against the washer, the washer having at least one limiting protrusion abutting against the circumferential inner sidewall of the housing assembly, the retaining spring being disposed on the side of the washer away from the deformable member, and the circumferential sidewall of the rotating body being provided with a limiting flange corresponding to the side of the retaining spring away from the washer.

[0013] In a preferred embodiment of this application, there are four first mating structures, and the angle between the line connecting two adjacent first mating structures and the center of the follower is 90 degrees. There are two second mating structures, and the angle between the line connecting the two second mating structures and the center of the positioning member is 180 degrees. The two second mating structures simultaneously mate with different first mating structures.

[0014] In a preferred embodiment of this application, the rotating body and / or follower has a first stop protrusion, and the circumferential inner sidewall of the housing assembly has a second stop protrusion that mates with the first stop protrusion.

[0015] In a preferred embodiment of this application, the circumferential sidewall of the rotating body corresponding to the end of the follower away from the positioning member has a stop flange, and the follower engages with the stop flange.

[0016] This application also provides a lamp that includes the aforementioned rotating device.

One end of the rotating assembly is located inside the housing assembly, and the other end of the rotating assembly is located outside the housing assembly.

[0018] When using the rotating device of this application, since one end of the rotating component is located outside the housing component and the rotating component can rotate relative to the housing component, the lamp head portion of the lamp can be installed on the part of the rotating component located outside the housing component, thereby enabling the rotation adjustment of the lamp head. Simultaneously, during the rotation of the rotating component relative to the positioning component, since the rotating component and the positioning component have mutually cooperating first and second mating structures, the lamp head portion can be positioned at different positions through the cooperation of the second mating structure with different first mating structures or the cooperation of the first mating structure with different second mating structures. When the first and second mating structures are contacting end faces, the rotating component can remain at any position during the relative positioning rotation process, or in other words, the rotation angle of the rotating component can be infinitely adjusted. Therefore, the rotating device of this application can achieve the rotational positioning of the rotating component solely through the cooperation of the rotating component and the positioning component. Therefore, the rotating device of this application has the characteristics of being able to rotate and position, and having a simple structure. Furthermore, the rotating device of this application effectively solves the problem of poor performance of rotatable lamps in the prior art. Attached Figure Description

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] To address the problem of poor performance of existing rotatable lamps, this application provides a rotating device and a lamp.

[0030] Furthermore, the lamp in this application has the following rotating device 80. Simultaneously, the lamp head can be mounted on the rotating body 10 of the rotating device 80 and rotate together with the rotating body 10.

[0031] As shown in Figures 1 to 7, the rotating assembly includes a housing assembly 20, a rotating component 1, and a positioning member 40. One end of the rotating component 1 is located inside the housing assembly 20, and the other end of the rotating component 1 is located outside the housing assembly 20. At least a portion of the rotating component 1 is rotatable relative to the housing assembly 20, and the portion of the rotating component 1 located inside the housing assembly 20 has a first mating structure 31. The positioning member 40 has a second mating structure 41, and at least one of the first mating structure 31 and the second mating structure 41 is at least two; or the first mating structure 31 and the second mating structure 41 are both one and are contacting end faces. The positioning member 40 is sleeved on the cylindrical portion 14 of the rotating component 1, and the rotating component 1 is rotatable relative to the positioning member 40.

[0032] When at least one of the first mating structure 31 and the second mating structure 41 is at least two, the first mating structure and the second mating structure are not end face mating. When the rotating assembly 1 rotates to different positions, the second mating structure 41 mates with different first mating structures 31 or the first mating structure 31 mates with different second mating structures 41, so that the rotating assembly 1 is kept in different positions.

[0033] When using the rotating device of this application, since one end of the rotating component is located outside the housing component and the rotating component can rotate relative to the housing component, the lamp head portion of the lamp can be installed on the part of the rotating component located outside the housing component, thereby enabling the rotation adjustment of the lamp head. Simultaneously, during the rotation of the rotating component relative to the positioning component, since the rotating component and the positioning component have mutually cooperating first and second mating structures, the lamp head portion can be positioned at different positions through the cooperation of the second mating structure with different first mating structures, or the cooperation of the first mating structure with different second mating structures, or different first mating structures with different second mating structures. When the first and second mating structures are contacting end faces, the rotating component can remain at any position during the relative positioning rotation process, or in other words, the rotation angle of the rotating component can be infinitely adjusted. Therefore, the rotating device of this application can achieve the rotation positioning of the rotating component solely through the cooperation of the rotating component and the positioning component. Thus, the rotating device of this application has the characteristics of being able to rotate and position, and having a simple structure. Furthermore, the rotating device of this application effectively solves the problem of poor performance of rotatable lamps in the prior art.

[0034] Specifically, the rotating assembly 1 includes a rotating body 10 and a follower 30. In one specific embodiment of this application, the rotating body 10 includes a cylindrical portion 14 and a mounting portion 15 connected to each other. One end of the rotating body 10 is located inside the housing assembly 20, and the other end of the rotating body 10 is located outside the housing assembly 20, and at least a portion of the rotating body 10 is rotatable relative to the housing assembly 20; the follower 30 has a first mating structure 31, and the follower 30 is sleeved on the cylindrical portion 14 of the rotating body 10 and rotates relative to the positioning member 40 together with the rotating body 10. Furthermore, when the follower 30 rotates to different positions with the rotating body 10, the second mating structure 41 engages with different first mating structures 31 or the first mating structure 31 engages with different second mating structures 41, so that the rotating body 10 and the follower 30 are held in different positions.

[0035] When using the rotating device of this application, since one end of the rotating body 10 is located outside the housing assembly 20 and the rotating body 10 can rotate relative to the housing assembly 20, the lamp head portion of the lamp can be installed on the part of the rotating body 10 located outside the housing assembly 20, thereby enabling the rotation adjustment of the lamp head. Simultaneously, during the process of the rotating body 10 driving the follower 30 to rotate relative to the positioning member 40, since the follower 30 and the positioning member 40 have mutually cooperating first and second mating structures 31, the lamp head portion can be positioned at different positions through the cooperation of the second mating structure 41 with different first mating structures 31, or the cooperation of the first mating structure 31 with different second mating structures 41, or the cooperation of different first mating structures 31 with different second mating structures 41. Therefore, the rotating device of this application can achieve the rotational positioning of the rotating body 10 solely through the cooperation of the follower 30 and the positioning member 40. Therefore, the rotating device of this application has the characteristics of being able to rotate and position, and having a simple structure. Furthermore, the rotating device of this application effectively solves the problem of poor performance of rotatable lamps in the prior art. When the first mating structure and the second mating structure are contacting end faces, the surface of the follower 30 and the positioning member 40 that are in contact with each other is the first mating structure and the second mating structure.

[0036] It should be noted that in this application, the rotating body can be made of metal, while the follower and positioning parts can be made of plastic. This arrangement aims to effectively prevent the positioning part from directly contacting the metal material through the cooperation between the follower and positioning parts, thereby reducing damage to the positioning part and extending its service life. Of course, in this application, the rotating body and follower can also be manufactured using a one-piece molding process.

[0037] It should be noted that, although the positioning member 40 is sleeved on the cylindrical part 14 of the rotating body 10 in this application, the positioning member 40 will not rotate with the rotating body 10. In order to achieve this effect, a protrusion that abuts against the inner sidewall of the housing assembly 20 can be provided on the circumferential sidewall of the positioning member 40, or the positioning member 40 can be set as a polyhedral structure. Of course, a connecting member can also be provided between the positioning member 40 and the housing assembly 20, as long as it can be ensured that the positioning member 40 will not rotate with the rotating body 10.

[0038] Optionally, both the follower 30 and the positioning member 40 are disposed inside the housing assembly 20.

[0039] Optionally, when the follower 30 rotates with the rotating body 10, it moves relative to the positioning member 40 in the axial direction of the rotating body 10, either towards or away from the positioning member 40. With this configuration, when the user operates the rotating body 10 to rotate relative to the housing assembly 20, the movement of the follower 30 relative to the positioning member 40 along the axial direction of the rotating body 10 provides the user with tactile and auditory feedback, making it easier for the user to determine whether the rotating body 10 has reached the correct position, thus enhancing the user experience. Of course, since the follower 30 and the positioning member 40 move relative to each other, the actual movement can be that the positioning member 40 moves within the housing assembly 20 along the axial direction of the rotating body 10 (i.e., the positioning member 40 moves up and down). Therefore, in this embodiment, the positioning member 40 has a cuboid structure, ensuring that while it can move along the axial direction of the rotating body 10, it also prevents the positioning member 40 from rotating with the rotating body 10 by engaging with the inner wall of the housing assembly 20.

[0040] Optionally, one of the first mating structure 31 and the second mating structure 41 is a positioning groove, and the other is a positioning protrusion. When the first mating structure 31 and the second mating structure 41 are mated together, at least a portion of the positioning protrusion is located inside the positioning groove. In a specific embodiment of this application, the follower 30 is located at the end of the positioning member 40 near the rotating body 10 outside the housing assembly 20. Alternatively, in this embodiment, the follower 30 is positioned above the positioning member 40. Furthermore, as shown in Figures 1, 4, and 5, the first mating structure 31 is a positioning groove, and the second mating structure 41 is a positioning protrusion. Of course, the relative position between the follower 30 and the positioning member 40 can be changed according to the actual usage. Preferably, the positioning groove and the positioning protrusion each have an arc-shaped chamfer, thereby ensuring that the positioning protrusion can more easily enter or exit the positioning groove during the process of the follower 30 rotating together with the rotating body 10. That is to say, in this application, the rotational positioning of the rotating body 10 can be achieved through the mutual cooperation of the positioning groove and the positioning protrusion. Furthermore, since the positioning protrusion makes a sound as it enters the positioning slot, it can serve as a reminder to the user.

[0041] Optionally, the rotating device further includes a deformable member 50, which is sleeved on the cylindrical portion 14 of the rotating body 10 and disposed on the side of the positioning member 40 away from the follower member 30. By providing the deformable member 50, the deformation of the deformable member 50 can provide clearance space for the movement of the positioning member 40, thereby ensuring that the positioning protrusion can more easily enter or exit the positioning groove.

[0042] Preferably, the deformable element 50 includes at least one of a spring and a silicone pad. Furthermore, as shown in FIG1, when the deformable element 50 is a spring, the deformable element 50 may be a wave spring.

[0043] Optionally, as shown in FIG1, the rotating device further includes a washer 60 and a retaining spring 70 respectively sleeved on the cylindrical portion 14 of the rotating body 10. One end of the deformable member 50 abuts against the side of the positioning member 40 away from the follower 30, and the other end of the deformable member 50 abuts against the washer 60. The washer 60 has at least one limiting protrusion 61 that abuts against the circumferential inner sidewall of the housing assembly 20. The retaining spring 70 is disposed on the side of the washer 60 away from the deformable member 50, and a limiting flange 11 is provided on the circumferential sidewall of the rotating body 10 corresponding to the side of the retaining spring 70 away from the washer 60. Of course, in this application, a receiving groove for accommodating the retaining spring 70 and / or the washer 60 may also be provided on the circumferential sidewall of the rotating body 10.

[0044] In one specific embodiment of this application, as shown in Figures 4 and 5, there are four first mating structures 31, with the angle between the line connecting two adjacent first mating structures 31 and the center of the follower 30 being 90 degrees. There are two second mating structures 41, with the angle between the line connecting the two second mating structures 41 and the center of the positioning member 40 being 180 degrees, and the two second mating structures 41 simultaneously mate with different first mating structures 31. This arrangement ensures better rotational positioning of the rotating body 10, and also facilitates the assembly and positioning of the follower 30 and the positioning member 40 during assembly by using the engagement of the first mating structures 31 and the second mating structures 41.

[0045] Optionally, the rotating body 10 and / or the follower 30 have a first stop protrusion 32, and the circumferential inner sidewall of the housing assembly 20 has a second stop protrusion 21 that mates with the first stop protrusion 32.

[0046] Preferably, as shown in Figures 3 and 4, the first stop protrusion 32 is disposed on the outer periphery of the follower 30 and extends radially along the rotating body 10. Furthermore, in this embodiment, when the rotation direction of the rotating body 10 is different, the first stop protrusion 32 can abut against both ends of the second stop protrusion 21, thereby limiting the rotation angle of the rotating body 10. In a specific embodiment of this application, the rotation angle of the rotating body 10 is less than or equal to 270 degrees. Of course, depending on different usage requirements, the maximum rotation angle of the rotating body 10 can be changed by altering the circumferential extension length of the second stop protrusion 21 on the circumferential inner sidewall of the housing assembly 20.

[0047] Optionally, the circumferential sidewall of the rotating body 10 corresponding to the end of the follower 30 away from the positioning member 40 has a stop flange 12, and the follower 30 engages with the stop flange 12. Preferably, the stop flange 12 extends radially along the rotating body 10. Furthermore, the stop flange 12 has an engagement opening 121, and the follower 30 has an engagement protrusion 33 extending axially along the rotating body 10 and engaging with the engagement opening 121. Through the mutual engagement of the engagement protrusion 33 and the engagement opening 121, it can be ensured that the follower 30 can rotate together with the rotating body 10.

[0048] Optionally, the rotating body 10 has a wire passage 13 at one end within the housing assembly 20. By providing the wire passage 13, space can be provided for the lamp holder's wires, ensuring that the rotating body 10 does not interfere with the wires while rotating the lamp holder, thus guaranteeing the rotation effect of the rotating body 10.

[0049] Optionally, the housing assembly 20 is composed of two parts joined together.

[0050] As can be seen from the above description, the embodiments of this application achieve the following technical effects:

[0051] 1. Effectively solves the problem of poor performance of rotatable lamps in existing technologies;

[0052] 2. Simple structure and stable performance.

[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
