[0042] Embodiment 1

[0043] like Figures 1 to 11 As shown, a stage light of the present embodiment is easy to inspect and maintain, and its structure includes a support arm 2, a lamp head 1, a pivot bracket 3 and an air duct assembly. The pivot bracket 3 and the air duct assembly can be selectively arranged on the lamp head 1 or the support arm 2. The lamp head 1 is rotatably connected to the support arm 2 through the pivot bracket 3. In the present embodiment, the pivot bracket 3 and the air duct assembly are assembled on the lamp head 1. The pivot bracket 3 is provided with a pivot hole 5, an air guide cover 4 and a rotating assembly. The pivot hole 5 is arranged corresponding to the rotation axis of the lamp head 1. The air guide cover 4 is used to introduce or distribute the air flow in the stage light. The lower end of the air guide cover 4 is connected to the air outlet of the air duct assembly, and the rotating assembly is used to drive the lamp head 1 to rotate, and the rotating assembly is assembled between the air guide cover 4 and the pivot hole 5 of the pivot bracket 3. Specifically, the rotating assembly includes a transmission gear 6 and a toothed belt 18. The transmission gear 6 is fixedly connected to the rotation axis of the lamp head 1, and the transmission gear 6 has an air hole 17. In addition, the lower end of the air guide cover 4 is movably connected to the air duct assembly, and the side of the air guide cover 4 that abuts against the rotating assembly is detachably connected to the pivot bracket 3 .

[0044] It can be understood that the stage light structure of the present embodiment connects the air guide cover 4 to the air duct assembly movably, and allows the side of the air guide cover 4 that abuts against the rotating assembly to be detachably connected to the pivot bracket 3 in the stage light. Since the air guide cover 4 is assembled between the pivot holes 5 of the pivot bracket 3, when the rotating assembly needs to be inspected and repaired, the air guide cover 4 can be moved on the air duct assembly by simply dismantling the connection between the air guide cover 4 and the pivot bracket 3. At this time, the air guide cover 4 can be controlled to move away from the rotating assembly on the pivot bracket 3 without blocking the rotating assembly. Therefore, there is no need to completely disassemble the air guide cover 4 and the air duct assembly, and the rotating assembly can be inspected and maintained smoothly. To a certain extent, the disassembly process of the stage light rotating assembly during inspection and repair can be simplified, and the operation is more convenient.

[0045] In one embodiment, specifically, a soft sleeve 7 is provided between the air guide cover 4 and the air duct assembly. Optionally, the soft sleeve 7 of this embodiment is an elastic silicone sleeve, and the upper end pipe opening and the lower end pipe opening of the soft sleeve 7 are respectively sleeved on the air outlet of the air guide cover 4 and the air outlet of the air duct assembly close to the air guide cover 4. It can be understood that the air guide cover 4 is connected to the air duct assembly through the soft sleeve 7, so that the air guide cover 4 can be movably connected to the air duct assembly. During the maintenance of the stage light, after the connection between the air guide cover 4 and the pivot bracket 3 is disassembled, since the soft sleeve 7 cannot stably support the air guide cover 4, the air guide cover 4 can move freely at the air outlet of the air duct assembly, thereby facilitating the air guide cover 4 to leave the rotating assembly on the pivot bracket 3, and the air guide cover 4 will not block the rotating assembly. Therefore, there is no need to completely disassemble the air guide cover 4 and the air duct assembly, and the rotating assembly can also be smoothly inspected and maintained. At the same time, since the interior of the soft sleeve 7 allows air flow to pass through, it can also ensure that the air outlet of the air guide cover 4 and the air outlet of the air duct component can normally conduct air flow to each other.

[0046] In one embodiment, specifically, a plurality of first mounting holes 101 are provided on the side wall of the soft sleeve 7, and correspondingly, a plurality of second mounting holes 102 are also provided on the air guide cover 4. During assembly, after the second mounting holes 102 are coaxially connected with the first mounting holes 101, the soft sleeve 7 and the air guide cover 4 are screwed to each other through the first mounting holes 101 and the second mounting holes 102, thereby ensuring a firm connection between the air guide cover 4 and the soft sleeve 7.

[0047] In one embodiment, specifically, a convex ring 71 is formed on the outer wall of the soft sleeve 7, and correspondingly, the inner walls on opposite sides of the pivot bracket 3 are symmetrically provided with clamping grooves 31. When the soft sleeve 7 is assembled to the pivot bracket 3, the convex ring 71 of the soft sleeve 7 is fitted into the two clamping grooves 31, thereby facilitating a more stable installation of the soft sleeve 7.

[0048] In one embodiment, specifically, the side of the air guide cover 4 away from the transmission gear 6 is open, and the side of the air guide cover 4 away from the transmission gear 6 is connected to the cover plate 15, the air guide cover 4 and the cover plate 15 are sealed and assembled with each other, and the outer wall of the soft sleeve 7 is sealed and sleeved between the air guide cover 4 and the cover plate 15, so that the sealed connection between the soft sleeve 7 and the air guide cover 4 can be ensured to ensure that the airflow will not leak.

[0049] In one embodiment, specifically, the air duct assembly includes an air duct connecting plate 8, which is used to guide the airflow in / out of the air guide cover 4, the air duct connecting plate 8 is connected to the pivot bracket 3, and the air duct connecting plate 8 is formed with a clamp 9 at the air outlet position of the air duct assembly. When connected with the soft sleeve 7, the clamp 9 of the air duct connecting plate 8 is sleeved on the soft sleeve 7, which facilitates the stable docking of the soft sleeve 7 with the air duct assembly.

[0050] In one embodiment, further, the air duct connecting plate 8 is integrally formed with an obliquely extending bending plate 81, and the outer edge of the bending plate 81 is sealed against the inner wall of the pivot bracket 3, thereby improving the air tightness of the air duct assembly in the pivot bracket 3, helping to prevent water vapor from leaking through the air duct to the inside of the pivot bracket 3, and preventing water vapor from entering the transmission gear 6, toothed belt 18 and even motor 19 in the rotating assembly in the pivot bracket 3.

[0051] In one embodiment, specifically, the air duct assembly also includes an air guide cavity 10 and an air duct baffle 11. The air guide cavity 10 is formed in the pivot bracket 3, and the air duct baffle 11 covers the cavity opening of the air guide cavity 10, so that it is convenient to form an air duct in the pivot bracket 3; and the air duct baffle 11 cooperates with the clamp 9 of the air duct connecting plate 8 to achieve mutual sealing and docking with the pipe opening of the soft sleeve 7, so that it can ensure that the pipe opening of the soft sleeve 7 is sealed and docked with the air guide cavity 10 in the pivot bracket 3; in addition, a ventilation hole 12 is also opened on the air duct baffle 11, so that the air guide cavity 10 can be connected with the outside, so that the airflow can flow into or out of the air guide cavity 10 through the ventilation hole 12.

[0052] In one embodiment, specifically, the outer wall of the lamp holder 1 is provided with a heat dissipation hole 13, and the heat dissipation hole 13 is connected with the ventilation hole 12 of the air guide cavity 10 inside the lamp holder 1, and a heat dissipation fan 14 installed inside the lamp holder 1 is provided between the ventilation hole 12 and the heat dissipation hole 13. Therefore, after the heat dissipation fan 14 is started, the airflow can flow between the ventilation hole 12 and the heat dissipation hole 13, and the airflow in the stage lamp can be discharged to the outside through the air guide cover 4, the soft sleeve 7, the ventilation hole 12 of the air guide cavity 10 and the heat dissipation hole 13, so as to realize the flow of airflow inside the stage lamp and achieve the purpose of heat dissipation. Of course, after the heat dissipation fan 14 is started, the external air can also be drawn into the lamp holder 1, and the airflow entering the lamp holder 1 from the heat dissipation hole 13 can enter the interior of the stage lamp through the ventilation hole 12, the air guide cavity 10, the soft sleeve 7 and the air guide cover 4, which can also achieve the effect of heat dissipation.

[0053] In one embodiment, optionally, the ventilation holes of the air guide cover 4 are provided with docking protrusions 16 extending along the direction close to the support arm 2, and the air holes 17 are step-shaped. When the air guide cover 4 is installed in the pivot bracket 3, the docking protrusions 16 of the air guide cover 4 are fitted and sleeved in the air holes 17, thereby making the assembly of the air guide cover 4 more stable.

[0054] In one embodiment, specifically, the outer periphery of the transmission gear 6 is meshed with a toothed belt 18, a motor fixing plate 21 is fixed on the pivot bracket 3, a motor 19 is mounted on the motor fixing plate 21, a driving gear 20 is sleeved on the rotating shaft of the motor 19, and the driving gear 20 and the toothed belt 18 are meshed with each other, so when the motor 19 is started, the transmission gear 6 can be driven to rotate through the toothed belt 18, and then the lamp head 1 can be driven to rotate.

[0055] In one embodiment, specifically, two third mounting holes 103 are integrally formed on the pivot bracket 3, and fourth mounting holes 104 are integrally formed on opposite sides of the air guide cover 4. During assembly, the third mounting hole 103 and the fourth mounting hole 104 are coaxially butted against each other, so that the pivot bracket 3 and the air guide cover 4 can be screwed to each other through the third mounting hole 103 and the fourth mounting hole 104. In addition, a fifth mounting hole 105 is integrally formed on the pivot bracket 3, and a sixth mounting hole 106 is provided on the air duct connection plate 8. The fifth mounting hole 105 and the sixth mounting hole 106 are coaxially butted against each other, so that the air duct connection plate 8 can be fixedly mounted on the pivot bracket 3 by screw connection.

[0056] Embodiment 2

[0057] The structure of this embodiment is similar to that of the first embodiment, except that the air guide cover 4 is not movably connected to the air duct assembly through the soft sleeve 7, but the air guide cover 4 is rotatably pivoted to the air duct assembly, that is, a pivot shaft is provided between the air guide cover 4 and the air duct assembly, so that the movably connected air guide cover 4 and the air duct assembly can be realized. When performing the maintenance work of the stage light, after the connection between the air guide cover 4 and the pivot bracket 3 is disassembled, since the air guide cover 4 is rotatably pivoted to the air duct assembly, the air guide cover 4 can freely move at the air outlet of the air duct assembly, so that the air guide cover 4 is easy to leave the rotating assembly on the pivot bracket 3, and the air guide cover 4 will not block the rotating assembly, so there is no need to completely disassemble the air guide cover 4 and the air duct assembly, and the rotating assembly can be smoothly inspected and maintained.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
