However, it should be understood that these descriptions are only for further explaining the features and advantages of the present utility model, rather than limiting the patent requirements of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0013] The present utility model will be further described below in conjunction with the drawings and preferred embodiments.

[0014] Embodiment 1

[0015] See Figure 1 and Figure 2As shown in the figure, a hall lighting adjustment device involved in this embodiment includes a frame 1 hoisted on the ceiling of the wall. Below the frame 1, there is a central lamp holder 2 for installing panel lights, a movable lamp holder 3 arranged outside the central lamp holder, and a fixed lamp holder 4 arranged outside the movable lamp holder. A suspension rod 5 is connected between the fixed lamp holder 4 and the frame 1. Telescopic rod assemblies 6 are connected between the central lamp holder 2 and the frame 1, and between the movable lamp holder 3 and the support 1. A traction cable 8 is passed through the frame 1, with one end connected to the central lamp holder 2 and the other end connected to a traction machine 7. The traction cable 8 is wound around the traction wheel of the traction machine 7. The traction machine 7 is fixed above the frame 1. A guide wheel 9 rotatably connected to the frame 1 is drivingly connected to the traction cable 8. On the outer side of the central lamp holder 2, there is a first retaining ring 10. On the inner side of the movable lamp holder 3, there is a second retaining ring 11 that blocks the upward movement of the first retaining ring. On the outer side of the movable lamp holder 3, there is a third retaining ring 12. On the inner side of the fixed lamp holder 4, there is a fourth retaining ring 13 that blocks the upward movement of the third retaining ring.

[0016] Further, the telescopic rod assembly 6 includes a number of tube sleeves 61 that are sleeved on each other in sequence from the outside to the inside and move axially relative to each other. The tube sleeves 61 are coaxially arranged. At the bottom of the upper tube sleeve among two adjacent tube sleeves 61, there is an inner retaining ring 62. At the top of the lower tube sleeve among two adjacent tube sleeves 61, there is an outer retaining ring 63. The outer retaining ring 63 is arranged above the inner retaining ring 62 that matches it. The top of the uppermost tube sleeve 61 is connected to the frame 1. The bottom of the lowermost tube sleeve 61 is connected to the central lamp holder 2 or the movable lamp holder 3.

[0017] Further, the central lamp holder 2 is in the shape of a circular sheet, and the movable lamp holder 3 and the fixed lamp holder 4 are both in the shape of a circular ring sheet.

[0018] Further, the central lamp holder 2, the movable lamp holder 3, and the fixed lamp holder 4 are coaxially arranged.

[0019] Further, the frame 1 is provided with a hoisting ear plate 14.

[0020] In this implementation scheme, by the traction machine 7 paying out the traction cable 8, the central lamp holder 2 connected thereto moves downward to the lowest position. At this time, the telescopic rod assembly 6 connected to the central lamp holder 2 extends to the longest. The movable lamp holder 3 also moves downward to the lowest position. At this time, the telescopic rod assembly 6 connected to the movable lamp holder 3 extends to the longest. The central lamp holder 2, the movable lamp holder 3, and the fixed lamp holder 4 are respectively arranged at different floor heights. Panel lights are arranged on the three of them, so that each light-emitting source is located at different vertical heights.

[0021] The winding traction cable 8 is driven by a traction machine 7 to move the central lamp holder 2 connected thereto upward. During this process, the first retaining ring 10 will encounter the second retaining ring 11. Continuing to move upward will cause the movable lamp holder 3 to also move upward. The traction cable 8 continues to wind until the third retaining ring 12 encounters the fourth retaining ring 13. At this time, the traction machine 7 stops winding. The central lamp holder 2, the movable lamp holder 3, and the fixed lamp holder 4 are arranged at the same vertical height. Panel lights are arranged on the three of them, so that each light-emitting source is located at the same vertical height.

[0022] The exhibition hall lighting adjustment device involved in the present invention realizes the lifting of the central lamp holder through the winding and unwinding of the traction cable. During the lifting process, the movable lamp holder can be linked to achieve the effect that the central lamp holder, the movable lamp holder, and the fixed lamp holder are arranged in a stacked manner or located on the same horizontal plane. By changing the light-emitting position of the light source, different display product effects can be achieved. The overall function is perfect and the practicability is strong.
