[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the directions under normal use, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use.

[0026] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0027] like Figures 1 to 3 As shown, this embodiment of the present invention provides a rotating assembly 10, including a rotating member 11 and a rotating shaft 12. Two rotating members 11 are provided, each with a receiving groove 111 formed thereon. The openings of the two receiving grooves 111 face opposite directions, and a connecting hole 112 is provided through the bottom wall of each rotating member 11 forming the receiving groove 111. The rotating shaft 12 has a fixed end 121 and a through end 122 facing each other. The fixed end 121 is connected to either rotating member 11, and the through end 122 passes through the two connecting holes 112 and is connected to the other rotating member 11 via a locking member 13, thereby movably connecting the two rotating members 11. Furthermore, the fixed end 121 and the through end 122 are located in different receiving grooves 111 and are not exposed, while the locking member 13 and the through end 122 are located in the same receiving groove 111.

[0028] Specifically, the connection between the fixed end 121 of the rotating shaft 12 and any rotating component 11 is typically a fixed connection, while the connection between the through end 122 of the rotating shaft 12 and another rotating component 11 via the locking component 13 is typically a movable connection. This allows the rotating component 11 connected to the through end 122 to rotate relative to the rotating shaft 12, thereby achieving relative rotation between the two rotating components 11. After the relative position between the two rotating components 11 is adjusted, it can be stably maintained without any loosening, thus meeting the requirement for adjusting the position between the two rotating components 11.

[0029] Optionally, to connect the through end 122 and the rotating member 11, the locking member 13 can be a snap ring, with a groove in the through end 122 for the snap ring to engage. The groove limits the snap ring, and the snap ring abuts against the bottom wall of the receiving groove 111 formed by the rotating member 11. This restricts the axial movement of the rotating shaft 12 and the rotating member 11, preventing them from loosening, while allowing relative rotation between the rotating shaft 12 and the rotating member 11, thus achieving a movable connection. Alternatively, the locking member 13 can be a nut, with an external thread on the rotating shaft 12, allowing the nut to engage with the external thread of the rotating shaft 12. The end face of the nut abuts against the bottom wall of the receiving groove 111 formed by the rotating member 11. In this way, the nut and the fixed end 121 together clamp and limit the connection between the two rotating members 11, while also allowing relative rotation between the rotating shaft 12 and the rotating member 11.

[0030] Of course, not only can the connection between the through end 122 and the corresponding rotating member 11 be made using the above-described movable connection method, but the connection between the fixed end 121 and the corresponding rotating member 11 can also be made using the above-described movable connection method, thus enabling relative rotation of the two rotating members 11. It can be understood that for the connection between the fixed end 121 and one of the rotating members 11, and the connection between the through end 122 and the other rotating member 11, at least one of the two connections needs to be a movable connection.

[0031] The connecting hole 112 on the rotating component 11 is usually circular, and the main body of the rotating shaft 12 located between the fixed end 121 and the through end 122 is usually cylindrical. Thus, the axis of the rotating shaft 12 is the axis of the cylinder. When the rotating shaft 12 passes through the connecting hole 112 of the two rotating components 11 and connects to them, the two rotating components 11 can rotate freely around the axis of the rotating shaft 12. To improve the smoothness of rotation and facilitate the assembly of the rotating shaft 12 and the rotating component 11, the diameter of the connecting hole 112 can be set slightly larger than the diameter of the rotating shaft 12, creating a certain gap between the inner wall of the connecting hole 112 formed by the rotating shaft 12 and the rotating component 11. This makes it easier for the through end 122 to pass through the connecting hole 112, facilitating assembly and connection, and allowing the rotating component 11 to rotate more smoothly relative to the rotating shaft 12.

[0032] Optionally, to improve rotational stability, a friction structure can be provided between the rotating shaft 12 and the connecting hole 112. This friction structure can be made of a material with a high coefficient of friction, such as rubber. The friction structure can be provided on the rotating shaft 12 or on the inner wall of the rotating member 11 where the connecting hole 112 is formed. When the rotating shaft 12 and the rotating member 11 are connected, the friction structure can fill the gap between the rotating shaft 12 and the connecting hole 112, ensuring stable contact between the rotating member 11 and the rotating shaft 12, thereby improving rotational stability. Furthermore, the frictional force applied by the friction structure prevents the rotating member 11 from loosening, thus holding the rotating member 11 in the desired position. Alternatively, the portion of the structure on the rotating shaft 12 that passes through the connecting hole 112 can be made of a material with a high coefficient of friction, or the portion of the structure on the rotating member 11 that forms the connecting hole 112 can be made of a material with a high coefficient of friction, similarly achieving the effect of improving rotational stability and preventing the rotating member 11 from loosening.

[0033] Optionally, the connection between the fixed end 121 and the rotating member 11 can be indirect through a connector, which can be designed with reference to the locking member 13. Of course, the connection between the fixed end 121 and the rotating member 11 can also be direct, for example, by using a fixed connection method such as adhesive bonding, or by providing a slot on the rotating member 11 so that the fixed end 121 can be inserted into the slot. This solution will be described in detail in the following embodiments.

[0034] It should be noted that, as Figure 3 As shown, the fixed end 121 and the through end 122 are respectively located in the receiving groove 111 formed by different rotating parts 11, and the locking part 13 is located in the receiving groove 111 where the through end 122 is located. Specifically, the depth of the receiving groove 111 can be designed according to the size of the fixed end 121, the through end 122 and the locking part 13, so as to ensure that the fixed end 121, the through end 122 and the locking part 13 do not protrude from the receiving groove 111.

[0035] The rotating assembly 10 provided in this embodiment of the utility model includes a rotating shaft 12 and two rotating parts 11. The two rotating parts 11 are respectively formed with receiving grooves 111 with openings facing opposite directions, and connecting holes 112 are respectively provided on the bottom wall of the receiving grooves 111. The fixed end 121 of the rotating shaft 12 is connected to one of the rotating parts 11, and the through end 122 passes through the connecting holes 112 of the two rotating parts 11 and is connected to the other rotating part 11 through the locking member 13, so that at least one rotating part 11 can rotate around the axis of the rotating shaft 12, thus realizing the movable connection of the two rotating parts 11. The structure is simple and the assembly operation is convenient. Meanwhile, this utility model embodiment also adopts a method in which both the fixed end 121 and the through end 122 are located in the receiving groove 111, and the locking member 13 connecting the through end 122 and the rotating member 11 is also located in the receiving groove 111. That is, neither the rotating shaft 12 nor the locking member 13 will protrude outside the receiving groove 111. In this way, when using the rotating assembly 10, the rotating shaft 12 and the locking member 13 are not easily observed by the user, resulting in a high degree of structural aesthetics. Moreover, the rotating shaft 12 and the locking member 13 are not easily subject to collisions or friction with the outside world, thereby ensuring the reliability of the rotating assembly 10.

[0036] In the application of the rotating assembly 10, two rotating parts 11 are typically connected to two structures that need to rotate relative to each other, thereby driving the relative rotation of the two structures through the rotating parts 11. Taking the application of the rotating assembly 10 in a lamp as an example, the two rotating parts 11 can be connected to the lamp holder and the lamp head of the lamp respectively, enabling the lamp head to rotate relative to the lamp holder to adjust the lighting direction of the lamp. Of course, it is understandable that the application scenarios of the rotating assembly 10 are quite extensive and not limited to lamps.

[0037] In some embodiments, such as Figure 1 and Figure 2 As shown, the rotating component 11 includes a body 113 and a fixing plate 114. The fixing plate 114 is connected to the body 113. The body 113 forms the sidewall of the receiving groove 111, and the fixing plate 114 forms at least part of the bottom wall of the receiving groove 111. A connecting hole 112 is formed through the fixing plate 114. Optionally, the fixing plate 114 and the body 113 can be connected and fixed by means of threaded connection, snap-fit ​​connection, adhesive bonding, etc.

[0038] It is understood that the bottom wall of the receiving groove 111 can be formed entirely by the fixing plate 114, or the fixing plate 114 can form part of the bottom wall, and the body 113 can form another part of the bottom wall. For example, in Figure 1 and Figure 2 In the rotating assembly 10 shown, the fixed plate 114 forms part of the bottom wall of the receiving groove 111, and a connecting hole 112 is opened on this part of the bottom wall to meet the structural requirements required during assembly.

[0039] In the above embodiments, by forming at least a portion of the bottom wall of the receiving groove 111 on the fixed plate 114, and by opening the connecting hole 112 on the fixed plate 114, when the locking member 13 connects the through end 122 to the corresponding rotating member 11, it can directly contact the fixed plate 114 without directly contacting the body 113. This reduces the squeezing wear of the locking member 13 on the body 113 and improves the service life of the body 113. Furthermore, the connection between the fixed plate 114 and the body 113 can be a detachable connection method such as a threaded connection or a snap-fit ​​connection. When the fixed plate 114 is worn or deformed, it is easy to disassemble and replace, which can better ensure the reliability of the connection.

[0040] In some embodiments, such as Figure 1 and Figure 2 As shown, the rotating assembly 10 also includes a cover plate 115, which is connected to the rotating component 11 and covers the opening of the receiving groove 111. Specifically, when the rotating component 11 includes a body 113 and a fixing plate 114, the cover plate 115 is connected to the body 113. To facilitate disassembly and maintenance, the connection between the cover plate 115 and the rotating component 11 can typically be a detachable connection method such as a threaded connection, a snap-fit ​​connection, or a magnetic connection.

[0041] The above embodiment uses a cover plate 115 to cover the opening of the receiving groove 111, which can shield the structure inside the receiving groove 111, further improving the aesthetics of the rotating assembly 10, enhancing the protection of structures such as the rotating shaft 12 and the locking member 13, and the cover plate 115 can prevent external debris from entering the receiving groove 111, preventing external debris from contaminating the internal space of the receiving groove 111, and improving the reliability of the overall structure rotation.

[0042] In some embodiments, such as Figure 1 and Figure 2 As shown, the cover plate 115 has at least one first insertion portion 1151 on the side facing the receiving groove 111, and a second insertion portion 1131 corresponding to the first insertion portion 1151 is provided in the receiving groove 111. Each first insertion portion 1151 is inserted into the corresponding second insertion portion 1131 to fix the cover plate 115 to the rotating member 11. It can be understood that the second insertion portion 1131 can be provided on the side wall of the rotating member 11 forming the receiving groove 111 or on the bottom wall, as long as it can achieve the function of being inserted into the first insertion portion 1151.

[0043] Optionally, multiple first insertion portions 1151 and second insertion portions 1131 may be provided respectively to enhance the stability of the cover plate 115. When multiple first insertion portions 1151 and second insertion portions 1131 are provided respectively, the shapes of each first insertion portion 1151 may be the same or different, as long as the shape of the second insertion portion 1131 is adapted to the shape of the first insertion portion 1151. For example, when the first insertion portion 1151 is a slot, the corresponding second insertion portion 1131 is a plug block, which can satisfy the one-to-one plugging of the first insertion portion 1151 and the second insertion portion 1131.

[0044] The above embodiment provides a specific scheme for connecting and fixing the cover plate 115 and the rotating member 11. By using a one-to-one corresponding insertion of the first insertion part 1151 and the second insertion part 1131, a detachable connection between the cover plate 115 and the rotating member 11 can be achieved, facilitating the disassembly of the cover plate 115 for maintenance or replacement. Of course, when the cover plate 115 and the rotating member 11 are connected by a non-detachable connection such as adhesive bonding, the first insertion part 1151 and the second insertion part 1131 can also be correspondingly inserted to achieve the installation and positioning function of the cover plate 115. In addition, by setting the first insertion part 1151 on the side of the cover plate 115 facing the receiving groove 111, and the second insertion part 1131 on the side wall of the rotating member 11 forming the receiving groove 111, after the cover plate 115 is installed, both the first insertion part 1151 and the second insertion part 1131 are hidden in the receiving groove 111 and not exposed, which can better maintain the simplicity and aesthetics of the external structure.

[0045] In some embodiments, such as Figure 1 and Figure 2 As shown, along the axial direction of the rotating shaft 12, the projected shape of the fixed end 121 is a polygon or a non-circular curved shape. A fixing groove 1132 is provided on the body 113 or fixing plate 114 connected to the fixed end 121, and the connecting hole 112 communicates with the fixing groove 1132. The contour shape of the fixing groove 1132 matches the contour shape of the fixed end 121, and the fixed end 121 is located within the fixing groove 1132. Specifically, since the bottom wall of the receiving groove 111 can be formed by the fixing plate 114, or by a combination of the fixing plate 114 and the body 113, and the fixed end 121 is located within the receiving groove 111, a fixing groove 1132 can be provided on the body 113 or fixing plate 112 to receive the fixed end 121 and limit the connection position of the fixed end 121, thereby achieving a reliable connection. The connecting hole 112 is connected to the fixing groove 1132, and the connecting hole 112 and the fixing groove 1132 can be arranged coaxially. Thus, after the through end 122 of the rotating shaft 12 passes through the connecting hole 112, the fixing end 121 can be positioned and limited within the fixing groove 1132. This design has a simple overall structure, is convenient for limiting installation, and has good reliability.

[0046] It should be noted that the projected shape of the polygon formed by the fixed end 121 refers to the shape being enclosed by multiple sides. These sides are not limited to straight lines; they can also be curved segments. For example, as... Figure 1 and Figure 2 As shown in the figure, the projected shape of the fixed end 121 along the axis of the rotating shaft 12 is formed by arcs and straight line segments, which is also a polygon described in this embodiment. Besides polygons, the shape of the fixed end 121 can also be a non-circular curved shape, that is, a non-circular shape formed by a curve, such as an ellipse or a rounded rectangle. Such shapes can also restrict the relative rotation between the rotating component 11 connected to the fixed end 121 and the rotating shaft 12. The contour shape of the fixing groove 1132 can be designed according to the contour shape of the fixed end 121, so that the shape of the fixing groove 1132 matches that of the fixed end 121.

[0047] In the above embodiments, by setting the shape of the fixed end 121 to a polygon or a non-circular curved shape, and adapting the outline shape of the fixed groove 1132 to the outline shape of the fixed end 121, the relative rotation between the rotating member 11 connected to the fixed end 121 and the rotating shaft 12 can be restricted when the fixed end 121 is inserted into the fixed groove 1132. Furthermore, the fixed end 121 can abut against the bottom wall of the fixed groove 1132. Combined with the through end 122 being connected to the body 113 of another rotating member 11 through the locking member 13, the relative fixation of the rotating shaft 12 and the two rotating members 11 in the axial direction can be achieved, preventing loosening when the two rotating members 11 rotate relative to each other, and ensuring a stable and reliable connection.

[0048] In some embodiments, such as Figure 1 and Figure 2 As shown, the through end 122 is provided with an external thread (not shown in the figure), and the locking member 13 is provided with a threaded hole 131. The threaded hole 131 is connected to the external thread, and the locking member 13 abuts against the bottom wall of the receiving groove 111 formed by the corresponding rotating member 11. Optionally, the locking member 13 can be made directly from a nut of a suitable specification, or it can be made by machining the threaded hole 131 on a non-standard workpiece.

[0049] It should be noted that the contact between the locking member 13 and the bottom wall of the receiving groove 111 formed by the rotating member 11 can be either the locking member 13 directly contacting the bottom wall of the receiving groove 111 formed by the rotating member 11, or it can be an indirect contact, that is, an intermediate structure is sandwiched between the locking member 13 and the bottom wall of the receiving groove 111 formed by the rotating member 11, and indirect contact is achieved through this intermediate structure.

[0050] In the above embodiments, by connecting the threaded hole 131 on the locking member 13 with the external thread on the through end 122, and by having the locking member 13 abut against the bottom wall of the receiving groove 111 formed by the corresponding rotating member 11, the loosening of the through end 122 in the axial direction of the rotating member 11 can be restricted, thereby achieving a reliable connection between the through end 122 and the rotating member 11, and further achieving a reliable connection between the two rotating members 11. This allows the two rotating members 11 to not only rotate and adjust their relative positions, but also to maintain a stable relative position at all times under the action of friction between the two rotating members 11, without loosening, thus meeting the usage requirement that the relative position can be stably maintained at all times after adjustment.

[0051] In some embodiments, such as Figure 1 and Figure 2 As shown, the rotating assembly 10 also includes a spring 14 and a washer 15. Regarding the specific positions of the spring 14 and the washer 15, optionally, in one embodiment, as... Figure 1 and Figure 2 As shown, along the direction from the through end 122 to the fixed end 121, the spring piece 14 and the washer 15 are sequentially disposed between the locking member 13 and the bottom wall of the corresponding rotating member 11 forming the receiving groove 111. The locking member 13 abuts against the bottom wall of the corresponding rotating member 11 forming the receiving groove 111 via the spring piece 14 and the washer 15. In another embodiment, along the direction from the fixed end 121 to the through end 122, the spring piece 14 and the washer 15 are sequentially disposed between the fixed end 121 and the bottom wall of the corresponding rotating member 11 forming the receiving groove 111. The fixed end 121 abuts against the bottom wall of the corresponding rotating member 11 forming the receiving groove 111 via the spring piece 14 and the washer 15. It is understood that the above two solutions do not conflict with each other and can be used individually or simultaneously.

[0052] The above embodiments employ the placement of the spring piece 14 and the washer 15 between the locking member 13 and the bottom wall of the corresponding rotating member 11 forming the receiving groove 111, and / or between the fixed end 121 and the bottom wall of the corresponding rotating member 11 forming the receiving groove 111. Depending on the specific placement of the spring piece 14 and the washer 15, they can improve connection stability, buffer compressive force, and reduce wear on related structures. For example, when the spring piece 14 and the washer 15 are placed between the locking member 13 and the bottom wall of the receiving groove 111 forming the receiving groove 111, the spring piece 14 can undergo elastic deformation when compressed by the locking member 13, applying an elastic force that tightly engages the internal thread of the threaded hole 131 with the external thread of the through end 122, achieving a pre-tightening effect. This ensures a stable and reliable threaded connection, preventing loosening and maintaining a reliable relative position between the two rotating members 11. Furthermore, the gasket 15 can buffer the squeezing force exerted by the spring sheet 14 on the bottom wall of the receiving groove 111 of the rotating member 11, and distribute the pressure evenly, thereby reducing local squeezing wear on the rotating member 11.

[0053] In some embodiments, the spring 14 is a spiral spring, that is, a spring with a spiral shape. When the spiral spring is compressed, it can produce more obvious deformation to apply a greater elastic force. In this way, the preload of the threaded connection between the locking member 13 and the through end 122 can be further improved, the preload effect can be improved, and the connection structure can be more stable and reliable.

[0054] In some embodiments, such as Figure 1 and Figure 2 As shown, the rotating assembly 10 also includes a connecting shaft 16, which is disposed on any of the rotating parts 11 for connection to an external structure. The axis of the connecting shaft 16 is not parallel to the axis of the rotating shaft 12. Optionally, the axis of the connecting shaft 16 and the axis of the rotating shaft 12 can be perpendicular to each other or at other angles, as long as the two axes are not parallel.

[0055] The above embodiment employs a connecting shaft 16 on any one of the rotating parts 11, with the axis of the connecting shaft 16 not parallel to the axis of the rotating shaft 12. When the connecting shaft 16 is connected to an external structure, it allows relative movement between the external structure and the rotating part 11 on the connecting shaft 16. This further increases the flexibility of adjustment based on the relative rotational adjustment between the two rotating parts 11, enabling multi-directional rotational adjustment.

[0056] like Figure 4As shown, this embodiment of the utility model also provides a lamp 100, including a lamp holder 20, a lamp head 30, and the aforementioned rotating assembly 10. Any one rotating component 11 is connected to or integrally formed with the lamp holder 20, and the other rotating component 11 is connected to or integrally formed with the lamp head 30. When any one of the rotating components 11 is provided with a connecting shaft 16, one of the lamp holder 20 and the lamp head 30 can also be connected to the connecting shaft 16, and the other can be connected to or integrally formed with the rotating component 11 without a connecting shaft 16.

[0057] The lamp 100 provided in this embodiment of the present invention, by employing the aforementioned rotating component 10, can satisfy the relative rotation between the lamp head 30 and the lamp holder 20, realizing flexible adjustment of the lighting position of the lamp head 30, and maintaining good stability after adjustment without easy loosening. Furthermore, the rotating shaft 12, locking element 13, and other structures in the rotating component 10 are not exposed on the rotating component 11, making the external structure simple and aesthetically pleasing, and less susceptible to damage from external factors, thus improving the overall aesthetics and reliability of the lamp 100. In addition, when any of the rotating components 11 is provided with a connecting shaft 16, by connecting one of the lamp holder 20 and the lamp head 30 to the connecting shaft 16, and the other to or integrally formed with the rotating component 11 without the connecting shaft 16, the position of the lamp head 30 relative to the lamp holder 20 can be adjusted through relative rotation of the two rotating components 11, or through relative rotation of the connecting shaft 16 with the connected component. This provides better adjustment flexibility.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
