[0031] Specifically, in order to achieve the purpose of a small-volume rail joint, this embodiment does not set a driving structure such as a circuit board. The rotating component is used to contact the rail for conduction. The conductive component 1 includes a live wire, a neutral wire and a ground wire. A commonly used conductive metal sheet structure is adopted, which is electrically connected to the rotating component, so that the lamp can be powered by the conductive component 1 to form a single-loop conductive structure. Among them, the assembly of the rotating shell 5 and the conductive sheet 6 of the rotating component is the existing technology. The rotating shell 5 is provided with a corresponding mounting position to install the conductive sheet 6, and the conductive sheet 6 protrudes from the rotating shell 5, such as Figures 1 to 3 , by controlling the rotation of the rotating shell 5, it is possible to control whether the conductive sheet 6 is in contact with the track. The housing only needs to be provided with corresponding rotating slots 2 for installing the rotating shell 5 and conductive slots 3 for installing the conductive component 1. Therefore, the housing has a small volume, and can be applied to tracks with small installation space, and also to lamps with less conductive control requirements.

[0032] Furthermore, when the handle 4 is fixed in the handle groove, the positional relationship between the handle 4 and the housing is as follows: Figure 2 As shown, the outer side of the handle 4 is maintained in the same plane as the shell, so after the shell is installed on the track, the shell together with the handle 4 can be hidden in the track, making the appearance of the track more neat and the installation of the lamp more beautiful. Compared with the way in which the handle 4 of the track joint is exposed outside the track in the prior art, the hidden structure of this embodiment is more practical.

[0033] Among them, the handle 4 is provided with a lock groove 8 on both sides, the outer shell is provided with a lock block 9, the lock block 9 is located in the handle groove, and when the handle 4 is limited in the handle groove, the lock block 9 is limited in the lock groove 8; the handle 4 is hinged with the rotating shell 5 through the rotating shaft 10, and when the handle 4 locks the rotating shell 5, the outer side of the handle 4 is in the same horizontal plane as the outer side of the outer shell. Further, a protrusion 11 is installed on the top of the rotating shell 5, the other end of the rotating shell 5 contacts the inner side of the outer shell, and the top side of the protrusion 11 is in the same horizontal plane as the outer side of the outer shell; the outer periphery of the protrusion 11 is arc-shaped; the protrusion 11 is provided with a U-shaped groove 12, the rotating shaft 10 is located in the U-shaped groove 12 and both ends are connected to the protrusion 11.

[0034] Specifically, Figure 6 and Figure 2 , locking grooves 8 are provided on both sides of the handle 4, and locking blocks 9 are provided on the housing. When the rotating block needs to be locked, the handle 4 is rotated until the handle 4 fits the housing, and the two locking blocks 9 are respectively located in the two locking grooves 8, so that the handle 4 is difficult to move without the assistance of external force, thereby fixing the rotating block. Among them, since one end of the handle 4 equipped with the rotating shaft 10 is a U-shaped structure, the extension Figure 7 During the rotation in the opposite direction of the arrow, the handle 4 will be gradually tightened until it is fixed to the housing; and when it is necessary to unlock and rotate, the handle 4 is extended Figure 7 The rotating block is unlocked by rotating the handle 4 in the direction of the arrow, and then the rotating block is driven to rotate, thereby controlling the conductive sheet 6 to connect or disconnect with the guide rail; when the conductive sheet 6 is disconnected from the guide rail, the housing can be taken out, that is, the guide rail is taken out of this embodiment. In this embodiment, the rotating housing 5 is installed in the housing, and the handle 4 can also be kept at the same level as the surface of the housing, thereby realizing a hidden connection with the guide rail.

[0035] The shell of this embodiment includes an upper shell 13 and a lower shell 14, a first clip 15 is installed on one side of the upper shell 13, a first slot 16 is provided on the other side of the upper shell 13, a second slot 17 is opened on one side of the lower shell 14, a second clip 18 is installed on the other side of the lower shell 14, the first clip 15 is snapped into the second slot 17, and the second clip 18 is snapped into the first slot 16.

[0036] Specifically, Figures 1 to 5 As shown, by setting the first clip 15 and the second clip 18, correspondingly cooperating with the first slot 16 and the second slot 17, the positioning and fixation of the upper shell 13 and the lower shell 14 during assembly are achieved, making the assembly of the upper shell 13 and the lower shell 14 simpler and does not require the assistance of other parts, which is convenient for production.

[0037] This embodiment also provides a lamp connection assembly for connecting the lamp to the track joint, such as Figures 8 to 10As shown, the lamp connection assembly includes a rotating member 19 and an assembly member 20 . The housing is provided with a lamp connection groove 21 . The assembly member 20 is used to be installed in the lamp connection groove 21 . The assembly member 20 is provided with a mounting hole 22 . The rotating member 19 can be rotatably assembled in the mounting hole 22 .

[0038] Among them, the assembly 20 is provided with a movable groove 23, and the movable groove 23 is equipped with a ball 24. The outer periphery of the rotating member 19 is provided with a limit member 25; the rotating member 19 rotates, driving the limit member 25 to rotate, and when the limit member 25 rotates to the movable groove 23, it drives the ball 24 to move until the ball 24 moves to the end of the movable groove 23 and no longer moves, so that the limit member 25 and the rotating member 19 stop rotating, and the outer periphery of the rotating member 19 is provided with a rubber ring 26, and the outer periphery of the rotating member 19 is provided with a first annular groove 27, and the assembly 20 is provided with a second annular groove 28, and the rubber ring 26 is limited between the second annular groove 28 and the first annular groove 27.

[0039] Specifically, Fig. 9 As shown, the rotating member 19 is rotatably connected to the assembly member 20, and the outer periphery of the rotating member 19 is provided with threads, so that it can be connected to the lamp and make the lamp rotate. The provision of the rubber ring 26 can increase the resistance between the rotating member 19 and the assembly member 20. At the same time, a C-shaped buckle 29 is also provided below the rotating member 19. The rotating member 19 is provided with a third annular groove for installing the C-shaped buckle 29, and is located below the assembly member 20. The C-shaped buckle 29 and the assembly member 20 are in abutment connection, so the rotation resistance of the rotating member 19 can be further increased by the C-shaped buckle 29, so that the rotating member 19 can be rotated and fixed at a certain required angle, that is, the lamp can be rotated and fixed at a certain angle. The specific rotation resistance of the rotating member 19 can be achieved by adjusting the resistance between the C-shaped buckle 29 and the assembly member 20.

[0040] Furthermore, in this embodiment, the cooperation between the ball bearing 24 and the stopper 25 can realize a 360-degree rotation angle range of the rotating member 19. The rotating member 19 rotates, driving the stopper 25 to rotate. When the stopper 25 moves to the movable groove 23, it pushes the ball bearing 24 to move in the movable groove 23. Fig.10 As shown in the figure, when the ball 24 is pushed to the end of the movable groove 23, the ball 24 stops moving and the rotating member 19 stops rotating; the rotating member 19 is controlled to rotate in the opposite direction until the ball 24 is pushed to move to the other end of the movable groove 23 to complete the rotation. That is, the angular range in which the rotating member 19 can rotate depends on the angle of rotation in two directions. Therefore, as long as the size of the movable groove 23 is controlled so that the length of the movable range of the ball 24 in the movable groove 23 is greater than the width of the ball 24 plus the limiting member 25, as long as the limiting member 25 can be moved from the movable groove 23, the rotating member 19 can rotate in the opposite direction. Fig.10By turning the rotating member 19 to point a, rotating one circle and returning to point a, a 360-degree rotation range of the rotating member 19 can be achieved, thereby achieving a 360-degree rotation of the lamp, satisfying more lighting angles, and having wide practicality.
