As used in this utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0032] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0033] See also Figure 1 and Figure 2 The utility model embodiment provides a track spotlight, including: a rotating arm 1, having a first connecting edge 11 and a second connecting edge 12 relative to each other; a rear cover assembly 2, having a third connecting edge 21 and a fourth connecting edge 22 relative to each other; a rotating member 3, passing through the third connecting edge 21, the first connecting edge 11, the second connecting edge 12 and the fourth connecting edge 22 in sequence, and the rear cover assembly 2 is rotatably connected to the rotating arm 1 through the rotating member 3; a spotlight 4, connected to the rear cover assembly 2; wherein the third connecting edge 21 is in contact with the first connecting edge 11, and the second connecting edge 12 is not in contact with the fourth connecting edge 22.

[0034] In this embodiment, in the prior art, the rotational connection between the rear cover assembly and the rotating arm often adopts a bilateral or multilateral contact method to ensure the stability of the connection. However, this method will not only cause the connection to become loose due to friction and wear during long-term rotation, but also has extremely high assembly dimensional accuracy requirements, and problems may arise due to improper assembly. Therefore, the utility model adopts a single-sided contact rotation method, that is, the third connecting edge 21 and the first connecting edge 11 remain in contact during the rotation process, while the second connecting edge 12 and the fourth connecting edge 22 remain non-contact. This rotational connection method not only solves the problem that the rear cover assembly 2 will become loose after long-term rotation, but also reduces the difficulty of assembly between the rear cover assembly 2 and the rotating arm 1, and reduces problems caused by improper assembly.

[0035] Further, such as Figure 3 As shown, the track spotlight further includes a fastener 5 , which is adjustably connected to one end of the rotating member 3 , and the fastener 5 and one end of the rotating member 3 form a rotating space 51 , and the third connecting edge 21 and the first connecting edge 11 are both located in the rotating space 51 .

[0036] In this embodiment, the fastener 5 may be a locking nut, and the rotating member 3 may be a rotating shaft. The rotating member 3 is provided with a thread that cooperates with the locking nut, so that the fastener 5 can rotate on the rotating member 3. When the fastener 5 rotates in the rotating space 51, the fastener 5 makes the third connecting edge 21 contact with the first connecting edge 11, and at the same time, when the rear cover assembly 2 rotates around the rotating arm 1 to adjust the angle, the fastening force of the fastener 5 on the rotating assembly prevents the rear cover assembly 2 from being loosened so easily when the angle of the spotlight 4 is adjusted.

[0037] It should be noted that the design of the rotating member 3 needs to take into account sufficient strength and durability to withstand the weight of the track spotlight and the wear and tear of long-term use. At the same time, the material and fastening degree of the rotating member 3 and the fastener 5 are also important factors affecting the smoothness and stability of adjustment.

[0038] Therefore, the fastener 5 and the rotating member 3 are made of plastic. First, the fastener 5 made of plastic can better provide fastening force for the fastener 5, so that the rear cover assembly 2 is not easy to loosen when the angle is adjusted for a long time. Secondly, the plastic material has good corrosion resistance and wear resistance, so that the fastener 5 and the rotating member 3 can be used for a long time without being damaged, thereby extending the service life of the entire track spotlight. Finally, the plastic material is lighter than the metal material, which helps to reduce the weight of the entire track spotlight and facilitates installation.

[0039] Furthermore, the track spotlight further comprises a first gasket 6, which is sleeved on the rotating member 3 and located between the first connecting edge 11 and the third connecting edge 21, and both sides of the first gasket 6 are smooth. In this embodiment, the first gasket 6 with both sides being smooth provides a smooth and friction-reducing effect for the contact between the first connecting edge 11 and the third connecting edge 21, and solves the problem of mutual wear when the first connecting edge 11 and the third connecting edge 21 are in contact. Specifically, the first gasket 6 is a copper gasket.

[0040] Furthermore, the track spotlight further comprises a second gasket 7, which is sleeved on the rotating member 3 and arranged between the fastener 5 and the third connecting edge 21, and both sides of the second gasket 7 are non-smooth surfaces. In this embodiment, the second gasket 7 with both sides being non-smooth surfaces, when the fastener 5 is rotated and fastened toward the first connecting edge 11 on the rotating member 3, the second gasket 7 provides a large friction force between the fastener 5 and the third connecting edge 21, so that when the rear cover assembly 2 rotates around the rotating arm 1, the rotation contact surface is only generated at the contact surface between the first connecting edge 11 and the third connecting edge 21, achieving the effect of unilateral rotation, and more effectively solving the problem that the rear cover assembly 2 will become loose due to long-term rotation.

[0041] Specifically, the two sides of the second gasket 7 are toothed surfaces. In this embodiment, the toothed surface can generate more bite points when in contact through its uneven structure, thereby providing sufficient friction for the second gasket 7, and the toothed structure is easy to process. At the same time, the toothed surface also has a certain elasticity and adaptability, and can compensate for unevenness caused by processing errors or installation errors to a certain extent.

[0042] Further, the rotating arm 1 includes a rotating portion 13, a first connecting edge 11 and a second connecting edge 12 are arranged on both sides of the rotating portion 13, the rear cover assembly 2 includes a rotating groove 23, a third connecting edge 21 and a fourth connecting edge 22 are arranged on both sides of the rotating groove 23, and the rotating portion 13 is rotatably arranged in the rotating groove 23. In this embodiment, the rotating portion 13 realizes relative rotation with the rear cover assembly 2 through the rotating member 3. The first connecting edge 11 and the second connecting edge 12 are arranged on both sides of the rotating portion 13, and they interact with the third connecting edge 21 and the fourth connecting edge 22 of the rear cover assembly 2 during the rotation process to jointly maintain the rotation relationship between the rotating arm 1 and the rear cover assembly 2, and when the rear cover assembly 2 rotates around the rotating portion 13, the first connecting edge 11 contacts the third connecting edge 21, and the second connecting edge 12 does not contact the fourth connecting edge 22. This rotation connection method not only solves the problem that the rear cover assembly 2 will become loose after long-term rotation, but also reduces the difficulty of assembling the rear cover assembly 2 and the rotating arm 1, and reduces the problems caused by improper assembly.

[0043] Specifically, a first through hole 111 is provided on the first connecting edge 11, a second through hole 121 is provided on the second connecting edge 12, a third through hole 211 is provided on the third connecting edge 21, and a fourth through hole 221 is provided on the fourth connecting edge 22. One end of the rotating member 3 passes through the third through hole 211, the first through hole 111, the second through hole 121 and the fourth through hole 221 in sequence.

[0044] A nylon washer 8 and a flat washer 9 are further provided between the second connecting edge 12 and the fourth connecting edge 22 , and the second connecting edge 12 and the fourth connecting edge 22 are not in contact with each other.

[0045] When assembling the rotating arm 1 and the rear cover assembly 2, first install the nylon washer 8 into the side of the fourth connecting edge 22 close to the third connecting edge 21, then install the flat washer 9 into the side of the fourth connecting edge 22 away from the third connecting edge 21, then install the first gasket 6 between the first connecting edge 11 and the third connecting edge 21, and then install the second gasket 7 into the side of the first connecting edge 11 away from the third connecting edge 21, install the fastener 5 into one end of the rotating part 3, and finally pass one end of the rotating part 3 through the third through hole 211, the first through hole 111, the second through hole 121 and the fourth through hole 221 in sequence, and tighten the rotating part 3 with the fastener 5.

[0046] Further, such as Figure 4As shown, the track spotlight also includes a power head 100, and the rotating arm 1 also includes a connecting portion 14, one end of the connecting portion 14 is axially rotatably connected to the power head 100, and the other end of the connecting portion 14 is connected to the rotating portion 13. The connecting portion 14 can rotate 350 degrees along the rotation axis of the rotating arm 1, and the rear cover assembly 2 can rotate 90 degrees along the rotating portion 13.
