For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Combine the following Figures 1 to 5 A rotating assembly provided by an embodiment of the present invention is described.

[0041] like Figures 1 to 4 As shown, an embodiment of the present invention provides a rotating assembly 1 suitable for adjusting the position of a main body of a lamp, that is, when the rotating assembly 1 rotates, the main body 2 of the lamp can rotate along with the rotating assembly 1 to change the lighting direction of the lamp.

[0042] The rotating assembly 1 includes: a base 11, a turntable 12, a rolling member 13 and a limiting member 14. The turntable 12 is used to connect the main body 2 of the lamp and adjust the position of the main body 2. The turntable 12 is rotatably arranged on the base 11, and a first limiting groove 121 is provided on the turntable 12; the rolling member 13 is rollably arranged between the base 11 and the turntable 12, and the rolling member 13 abuts against the base 11 and the turntable 12. The limiting member 14 is arranged in the first limiting groove 121 and connected to the base 11. The limiting member 14 is slidably matched with the first limiting groove 121. When the turntable 12 rotates relative to the base 11, one end of the limiting member 14 slides in the first limiting groove 121.

[0043] Specifically, the base 11 is arranged at the bottom, the turntable 12 is arranged at a distance from the base 11, the main body 2 of the lamp is arranged on the turntable 12, and the rolling member 13 is rollably arranged between the base 11 and the turntable 12, that is, the turntable 12 is rotatably arranged on the base 11 through the rolling member 13. The turntable 12 is provided with a first limiting groove 121, and the first limiting groove 121 can be located on a side of the turntable 12 close to the base 11 or penetrate the entire turntable 12. The two ends of the limiting member 14 are respectively arranged on the first limiting groove 121 and the base 11.

[0044] When the rotation of the main body 2 needs to be controlled, the turntable 12 can be directly controlled to rotate relative to the base 11. Driven by the turntable 12, the rolling member 13 rolls between the base 11 and the turntable 12. The rolling of the rolling member 13 ensures smooth and stable rotation. At the same time, since one end of the limiter 14 slides in the first limiter groove 121, and the other end of the limiter 14 is always connected to the base 11, the turntable 12 and the base 11 can rotate in a preset rotation path under the restriction of the limiter 14. The limiter 14 limits the rotation to a certain extent, thereby ensuring that the main body 2 can move in a preset running track.

[0045] The rotating assembly provided by the present invention is configured such that a turntable 12 for connecting the main body 2 is arranged on the base 11, a first limiting groove 121 is arranged on the turntable 12, and a rolling member 13 is arranged between the base 11 and the turntable 12; the limiting member 14 is arranged in the first limiting groove 121 and connected to the base 11, so that during the rotation of the turntable 12 relative to the base 11, the rolling member 13 rolls between the base 11 and the turntable 12, and the limiting member 14 can slide under the restriction of the first limiting groove 121, so that the main body 2 can slide on the turntable 12, thereby effectively ensuring the rotation effect of the main body 2.

[0046] It should be noted that if it is necessary to reduce the friction of the rolling element 13 and the weight of the entire rotating assembly 1, the base 11 and the rotating disk 12 can be made of polyoxymethylene resin. If it is necessary to increase the durability of the entire rotating assembly 1, the base 11 and the rotating disk 12 can also be made of metal.

[0047] In one embodiment, Figures 1 to 6 As shown, one of the base 11 and the turntable 12 is provided with a second limiting groove 111, and the other of the base 11 and the turntable 12 is provided with a third limiting groove 122 corresponding to the second limiting groove 111, that is, the second limiting groove 111 and the third limiting groove 122 are respectively provided in the base 11 and the turntable 12, and the orthographic projection of the third limiting groove 122 is within the projection range of the second limiting groove 111, and the rolling element 13 is provided in the second limiting groove 111 and the third limiting groove 122. In the process of rotation of the turntable 12 relative to the base 11, the rolling element 13 rolls in the second limiting groove 111 and the third limiting groove 122 at the same time, and the second limiting groove 111 rotates relative to the rolling element 13.

[0048] Specifically, in this embodiment, a second limiting groove 111 is provided on the side of the base 11 close to the turntable 12, and a third limiting groove 122 is provided on the side of the turntable 12 close to the base 11. The rolling element 13 is arranged in both the second limiting groove 111 and the third limiting groove 122. When the turntable 12 rotates relative to the base 11, the third limiting groove 122 pushes the rolling element 13 to roll in the second limiting groove 111, thereby reducing the rotation resistance and ensuring smooth and stable rotation.

[0049] Furthermore, in another embodiment, a plurality of rolling elements 13 are provided, a second limiting groove 111 is provided in an annular manner on one side of the base 11 close to the turntable 12, and a plurality of third limiting grooves 122 are provided on one side of the turntable 12 close to the base 11. The plurality of third limiting grooves 122 are evenly distributed along the annular shape and are all within the projection range of the second limiting groove 111.

[0050] Since a single rolling element 13 is difficult to ensure the stability between the base 11 and the turntable 12, it is generally necessary to set a plurality of symmetrically arranged rolling elements 13 to ensure the stability of the base 11 and the turntable 12 during rotation. In this embodiment, four rolling elements 13 are provided, and four third limiting grooves 122 are provided on the four edges of one side of the turntable 12. The base 11 is provided with second limiting grooves 111 corresponding to the four third limiting grooves 122, and the second limiting grooves 111 are arranged in an annular shape. When the turntable 12 rotates relative to the base 11, the four rolling elements 13 roll in the second limiting grooves 111 under the push of the corresponding third limiting grooves 122.

[0051] In one example, if Figures 1 to 6As shown, the base 11 and the turntable 12 both adopt a circular ring structure, and the first limiting groove 121 is arranged in a ring shape at the edge of one side of the turntable 12. Therefore, when the turntable 12 rotates relative to the base 11, since one end of the limiting member 14 slides in the first limiting groove 121, and the other end of the limiting member 14 is always connected to the base 11, the turntable 12 and the base 11 can rotate in a preset annular path under the restriction of the limiting member 14, and the limiting member 14 has a certain limit on the rotation, thereby ensuring that the main body 2 can move in a preset annular track.

[0052] Since the limitation of a single limit member 14 can easily cause instability on both sides of the turntable 12 when it rotates, according to needs, the first limit groove 121 includes: a plurality of sliding sections arranged in sequence and spaced apart, a plurality of limit members 14 are provided, and the plurality of limit members 14 are arranged in a one-to-one correspondence with the plurality of sliding sections, and one end of each limit member 14 is arranged in the corresponding sliding section.

[0053] In this embodiment, Figure 2 As shown, the first limiting groove 121 includes two sliding sections, namely the first sliding section 1211 and the second sliding section 1212, and the first sliding section 1211 and the second sliding section 1212 extend in a semi-circular shape. The limiting member 14 is provided with two, namely the first limiting member 141 and the second limiting member 142. One end of the first limiting member 141 is arranged on the first sliding section 1211, and the other end of the first limiting member 141 is connected to the base 11. One end of the second limiting member 142 is arranged on the second sliding section 1212, and the other end of the second limiting member 142 is connected to the base 11. Under the restriction of the first limiting member 141 and the second limiting member 142, the turntable 12 can rotate in a small range (less than 180 degrees) relative to the base 11.

[0054] In other embodiments, the first limiting groove 121 may be further divided into more sliding sections to further ensure the stability of the rotating disk 12 during rotation.

[0055] Based on the above embodiments, in one embodiment, Figures 1 to 6 As shown, a long stepped groove 1210 is provided in the first limiting groove 121, and the stepped groove 1210 extends along the annular track of the first limiting groove 121, one end of the limiting member 14 is clamped in the stepped groove 1210, the limiting member 14 and the stepped groove 1210 are slidably matched, and the other end of the limiting member 14 passes through the stepped groove 1210 and is connected to the base 11. By providing the stepped groove 1210, it is possible to ensure that the limiting member 14 moves along the stepped groove 1210.

[0056] When the rotation of the main body 2 needs to be controlled, the turntable 12 can be directly controlled to rotate relative to the base 11. Driven by the turntable 12, the rolling element 13 rolls between the base 11 and the turntable 12. The rolling of the rolling element 13 ensures smooth and stable rotation. At the same time, since one end of the limiter 14 slides in the step groove 1210, the step groove 1210 can accurately limit the limiter 14, and the other end of the limiter 14 is always connected to the base 11, so that the turntable 12 and the base 11 can rotate in a preset rotation path under the restriction of the limiter 14. The step groove 1210 cooperates with the limiter 14 to limit the rotation to a certain extent, thereby ensuring that the main body 2 can move in a preset running track.

[0057] It should be noted that, in order to simplify the overall structure, the step groove 1210 may not be provided in the first limiting groove 121. One end of the limiting member 14 is directly provided in the first limiting groove 121, and the other end of the limiting member 14 is connected to the base 11. In this case, the limiting member 14 is provided between the base 11 and the turntable 12.

[0058] Based on the above embodiments, in one embodiment, Figures 1 to 6 As shown, the rolling member 13 is a ball bearing, which is spherically arranged between the base 11 and the turntable 12, and can be made of stainless steel balls, plastic balls or other materials. The limiting member 14 is a screw, and the screw is selected to be a model of M3*6. The screw includes a stud part and a nut part connected to each other, wherein the nut part is arranged in the stepped groove 1210 of the first limiting groove 121, and the stud part passes through the stepped groove 1210 to connect with the base 11.

[0059] The present invention also provides a lamp, such as Figures 1 to 6 As shown, the lamp includes a main body 2 and a rotating assembly 1. The rotating assembly 1 includes: a base 11, a turntable 12, a rolling member 13 and a limiting member 14. The turntable 12 is used to connect the main body 2 of the lamp and adjust the position of the main body 2. The turntable 12 is rotatably arranged on the base 11, and a first limiting groove 121 is provided on the turntable 12; the rolling member 13 is rollably arranged between the base 11 and the turntable 12, and the rolling member 13 abuts against the base 11 and the turntable 12. The limiting member 14 is arranged in the first limiting groove 121 and is connected to the base 11. The limiting member 14 is slidably matched with the first limiting groove 121. During the rotation of the turntable 12 relative to the base 11, one end of the limiting member 14 slides in the first limiting groove 121.

[0060] When the rotation of the main body 2 needs to be controlled, the turntable 12 can be directly controlled to rotate relative to the base 11. Driven by the turntable 12, the rolling member 13 rolls between the base 11 and the turntable 12. The rolling of the rolling member 13 ensures smooth and stable rotation. At the same time, since one end of the limiter 14 slides in the first limiter groove 121, and the other end of the limiter 14 is always connected to the base 11, the turntable 12 and the base 11 can rotate in a preset rotation path under the restriction of the limiter 14. The limiter 14 limits the rotation to a certain extent, thereby ensuring that the main body 2 can move in a preset running track.

[0061] The lamp provided by the present invention is configured such that a turntable 12 for connecting a main body 2 is arranged on a base 11, a first limiting groove 121 is arranged on the turntable 12, and a rolling member 13 is arranged between the base 11 and the turntable 12, one end of the limiting member 14 is arranged in the first limiting groove 121, and the other end of the limiting member 14 is connected to the base 11, so that when the turntable 12 rotates relative to the base 11, the rolling member 13 rolls between the base 11 and the turntable 12, and the limiting member 14 can slide under the restriction of the first limiting groove 121, so that the main body 2 can slide on the turntable 12, thereby effectively ensuring the rotation effect of the main body 2.

[0062] To coordinate the installation of the main body 2 and the rotating assembly 1, as Figure 7 , Figure 8 and Fig. 9 As shown, the lamp also includes: a base 3 and a cover plate 4.

[0063] Among them, a receiving groove 31 is constructed on one side of the base 3, and the other side of the base 3 is connected to the main body 2. The cover plate 4 is arranged at the notch of the receiving groove 31, and the cover plate 4 is used to close the entire receiving groove 31. The rotating component 1 is arranged in the receiving groove 31, and the turntable 12 and the base 11 are both arranged in the receiving groove 31. The turntable 12 is connected to the bottom of the receiving groove 31, and the side of the base 11 away from the turntable 12 is connected to the cover plate 4.

[0064] Specifically, a gasket 5 is provided on one side of the cover plate 4 away from the base 3, and the cover plate 4 can be set on the ground through the gasket 5. The base 3 is set on the cover plate 4, and the upper surface of the base 3 is connected to the main body 2. When it is necessary to control the rotation of the main body 2, since the main body 2 is set with the turntable 12 through the base 3, the main body 2 can be directly rotated, and the main body 2 drives the turntable 12 to rotate through the base 3. The base 11 is fixed under the restriction of the gasket 5 on the cover plate 4, so that the turntable 12 can be controlled to rotate relative to the base 11. Under the drive of the turntable 12, the rolling member 13 rolls between the base 11 and the turntable 12, and the rolling of the rolling member 13 ensures smooth and stable rotation. At the same time, since one end of the limiter 14 slides in the first limiter groove 121, and the other end of the limiter 14 is always connected to the base 11, the turntable 12 and the base 11 can rotate in a preset rotation path under the restriction of the limiter 14, and the limiter 14 plays a certain limit on the rotation, thereby ensuring that the main body 2 can move under the preset running track.

[0065] Furthermore, if Fig. 9 As shown, the lamp further includes: a functional module 6. The functional module 6 is electrically connected to the main body 2. The functional module 6 can be a power supply or other functional device used in conjunction with the main body 2. The turntable 12 is provided with a first notch, the base 11 is provided with a second notch corresponding to the first notch, the bottom of the accommodating groove 31 cooperates with the cover plate 4 to form an installation cavity at the first notch and the second notch, and the functional module 6 is arranged in the installation cavity, and the functional module 6 is electrically connected to the main body 2.

[0066] In this embodiment, the turntable 12 and the base 11 both adopt a circular ring structure, a circular first notch is provided at the center of the turntable 12, a circular second notch is provided on the base 11, the bottom of the accommodating groove 31 closes the side of the first notch away from the second notch, and the cover plate 4 closes the side of the second notch away from the first notch, thereby forming a cylindrical installation cavity. The functional module 6 is arranged in the cylindrical installation cavity. When the turntable 12 rotates relative to the base 11, the turntable 12 will not come into contact with the functional module 6 in the installation cavity.

[0067] It is understandable that the rotating assembly 1 provided by the present invention is also applicable to other structural products with uncertain dimensions and requiring the ability to rotate, in addition to lamps, and this is not limited here.

[0068] The above described embodiments are merely illustrative, and some or all of the modules may be selected according to actual needs to achieve the purpose of the embodiments. Those skilled in the art may understand and implement the embodiments without creative effort.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
