[0039] Example 2

[0040] Based on example 1, as Figures 1 to 6The utility model provides a lamp rail, the rail body 1 is pivoted with the baffle 4. The rail body 1 is equipped with two second cavities 10 and two pivot shafts 6, and the second cavities 10 are located on both sides of the mounting cavity 2. The lower end of the second cavity 10 is provided with an opening, and the pivot shaft 6 is arranged in the second cavity 10. In the baffle assembly 3, the plurality of baffles 4 are divided into two groups and arranged oppositely. Each group is pivoted with the pivot shaft 6 on the side. The baffle 4 includes a first shielding part 7, a second shielding part 8, and a pivot part 9. The first shielding part 7 is perpendicular to the second shielding part 8. In the shielding state, the first shielding part 7 of the baffle 4 is arranged horizontally. The first shielding part 7 of the oppositely arranged baffles 4 collectively forms a shielding surface to shield the opening of the mounting cavity 2. At the same time, the first shielding part 7 of each group of baffles 4 shields the opening of the second cavity 10 on each side. The second shielding part 8 is arranged vertically and extends into the second cavity 10. When the baffle 4 is in the avoidance state, the first shielding part 7 of each group of baffles 4 is arranged vertically and extends into the mounting cavity 2. The second shielding part 8 is arranged horizontally and shields the opening of the second cavity 10 on each side. In the baffle 4, one end of the pivot part 9 is connected to the second shielding part 8, and the other end is pivoted to the pivot shaft 6. The pivot part 9 includes a C-shaped rotating part 16 arranged with an opening on one side. The inner side of the C-shaped rotating part 16 is adapted to the pivot shaft 6.

The second cavity 10 is used to accommodate the pivot shaft 6 and the pivot part 9, which separates the pivot part 9 from the first shielding part 7, so that the pivot part 9 will not hinder the installation of the lamp. The second shielding part 8 is arranged, so that no matter the baffle plate 4 is in the shielding state or the avoiding state, the opening of the second cavity 10 is shielded by the first shielding part 7 or the second shielding part 8, so that the pivot shaft 6 and the pivot part 9 in the second cavity 10 are not exposed outside the track body 1, improving the overall aesthetics. At least part of the C-shaped rotating part 16 is always located above the pivot shaft 6, so that the pivot part 9 remains connected with the pivot shaft 6 and will not fall off during normal use; the opening size of the C-shaped rotating part 16 is larger than the diameter of the pivot shaft 6, so that the pivot part 9 can be directly connected with the pivot shaft 6 at any position, and the installation is fast. The baffle plate 4 not in the installation position remains in the shielding state under the action of gravity, and the baffle plate 4 in the installation position will recover to the shielding state from the avoiding state under the influence of gravity after the lamp is removed from the track body 1.

The user can adjust the position of the baffle 4 according to the installation position of the lamp and the actual demand. The practicability of the lamp track is increased. The sheath ring 17 is arranged to prevent the baffle 4 from sliding off from the two ends of the pivot shaft 6. In another embodiment, the pivot shaft 6 is connected by a plurality of short shafts arranged at intervals. When the track is bent and deformed due to external force or other factors, the short shafts can be adjusted in angle relatively independently.
