[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0052] In the embodiments of the present invention, please refer to Figures 1 to 7 , a stage lamp hanging device, including a mounting plate 1 and a suspension rod 7. The mounting plate 1 is provided with mounting holes. The suspension rod 7 is located at the bottom of the mounting plate 1. The suspension rod 7 is used for hanging stage lamps, and further includes:

[0053] Connecting plate 2, connected to the bottom of the mounting plate 1;

[0054] Y-axis lifting mechanism 3, one end connected to the connecting plate 2, for driving the suspension rod 7 to move longitudinally in the Y-axis direction;

[0056] Fixed folding rod 6, connected to the suspension rod 7;

[0057] XZ-plane position adjusting mechanism 5, one end connected to the fixed folding plate 4 and the other end connected to the fixed folding rod 6, for adjusting the position of the suspension rod 7 in the XZ plane. The XZ-plane position adjusting mechanism 5 includes:

[0058] Rotating disk 51, rotatably connected to the top of the fixed folding plate 4;

[0059] The power adjustment assembly 52 is rotatably connected to the rotating disk 51 at one end and rotatably connected to the fixed folding rod 6 at the other end, and is used to drive the suspension rod 7 to move in the XZ plane;

[0060] The direction adjustment assembly 53 is connected to the rotating disk 51 at one end and connected to the fixed folding plate 4 at the other end, and is used to drive the rotating disk 51 to rotate, thereby adjusting the movement direction of the suspension rod 7;

[0061] The movement stability assembly 54 is connected to the rotating disk 51 at one end and connected to the fixed folding rod 6 at the other end, and is used to ensure the stability of the suspension rod 7 during movement.

[0062] Lower the height of the suspension rod 7 through the Y-axis lifting mechanism 3. After hanging the stage lamp on the suspension rod 7, raise the suspension rod 7 through the Y-axis lifting mechanism 3, so as to hang the stage lamp in the air. When it is necessary to adjust the position of the suspended lamp, according to the direction in which the suspended lamp is to move, drive the rotating disk 51 to rotate through the direction adjustment assembly 53, and then drive the power adjustment assembly 52 and the movement stability assembly 54 to rotate. The direction of the suspension rod 7 remains unchanged, and the power adjustment assembly 52 drives the suspension rod 7 to move in the XZ plane, thereby adjusting the position of the stage lamp, and the movement stability assembly 54 ensures the stable movement of the suspension rod 7.

[0063] As an embodiment of the present invention, please refer to Figures 1 to 5 , the Y-axis lifting mechanism 3 includes:

[0064] The driving member 31 is connected to the connecting plate 2;

[0065] The winding roller 32 is connected to the output end of the driving member 31;

[0066] The steel wire rope 33 is wound around the winding roller 32, and one end is connected to the winding roller 32 and the other end is connected to the fixed folding plate 4;

[0067] The limiting assembly 34 is connected to the connecting plate 2 at one end and connected to the fixed folding plate 4 at the other end, and is used to limit and fix the fixed folding plate 4.

[0068] When lowering the suspension rod 7, the driving member 31 drives the winding roller 32 to rotate, and the winding roller 32 unwinds the steel wire rope 33, so that the height of the fixed folding plate 4 decreases, thereby causing the height of the suspension rod 7 to decrease. After hanging and fixing the stage lamp on the suspension rod 7, the driving member 31 drives the winding roller 32 to rotate in the reverse direction, winds the steel wire rope 33, so that the height of the fixed folding plate 4 rises, thereby hanging the stage lamp in the air. The limiting assembly 34 limits the fixed folding plate 4 to prevent the position of the fixed folding plate 4 from shifting when the position of the suspension rod 7 changes. The driving member 31 can be a stepping motor, a servo motor, etc.

[0072] In the initial state, the lower insertion cylinder 342 is inserted into the upper cartridge 341. When the suspension rod 7 is lowered, the lower insertion cylinder 342 descends along with the fixed folding plate 4 and disengages from the upper cartridge 341. When the suspension rod 7 rises, the lower insertion cylinder 342 is inserted into the upper cartridge 341. When the bottom of the upper cartridge 341 abuts against the top of the fixed folding plate 4, the suspension rod 7 stops rising. The upper cartridge 341 and the lower insertion cylinder 342 cooperate to limit the position of the fixed folding plate 4, and the shape of the upper part being smaller and the lower part being larger at the top of the lower insertion cylinder 342 and the bottom of the upper cartridge 341 facilitates the insertion of the lower insertion cylinder 342 into the upper cartridge 341.

[0073] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 , the power adjustment component 52 includes:

[0077] The sliding folding rod 524 is connected to the toothed plate 523, and the sliding folding rod 524 penetrates through the rotating disk 51 and is slidably connected thereto;

[0078] The folding rod sleeve 525 has its top end connected to the toothed plate 523 and its bottom end rotatably connected to the fixed folding rod 6;

[0079] The first limiting sliding groove 526 is slidably connected to the bottom of the folding rod sleeve 525, and the first limiting sliding groove 526 is connected to the rotating disk 51.

The bottom ends of the two folding rods are both connected to the bearing sleeve, the top ends of the two folding rods are respectively connected to both ends of the toothed plate 523, and the bearing sleeve is rotatably connected to the fixed folding rod 6.

[0081] When the position of the stage lamp needs to be adjusted, the second driving member 521 drives the first gear 522 to rotate. The first gear 522 drives the toothed plate 523 to move. The toothed plate 523 drives the sliding folding rod 524 to move. The sliding folding rod 524 ensures the stability of the toothed plate 523 during movement. The toothed plate 523 drives the folding rod sleeve 525 to move linearly along the first limiting sliding groove 526. The folding rod sleeve 525 drives the fixed folding rod 6 and the suspension rod 7 to move linearly synchronously, thereby adjusting the position of the stage lamp. The second driving member 521 can be a stepping motor, a servo motor, etc.

[0082] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 , the direction adjustment assembly 53 includes:

[0086] When the position of the stage lamp needs to be adjusted, according to the position to be adjusted of the stage lamp, the third driving member 531 drives the second gear 532 to rotate. The second gear 532 drives the external toothed ring 533 to rotate. The external toothed ring 533 drives the rotating disk 51 to rotate in the XZ plane. The rotating disk 51 drives the first limiting sliding groove 526 to rotate synchronously, so that the position where the stage lamp is to reach is located on the extending direction of the first limiting sliding groove 526, and the suspension rod 7 does not rotate. The third driving member 531 can be a stepping motor, a servo motor, etc.

[0087] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 , the movement stability assembly 54 includes:

[0088] A transmission mechanism 541, one end of which is connected to the rotating disk 51;

[0089] A rotating limiting rod 542, passing through the fixed folding plate 4 and rotatably connected thereto. The rotating limiting rod 542 is connected to the other end of the transmission mechanism 541;

[0092] Rotate the connecting rod 545, the top end is rotatably connected to the bottom of the second limiting sliding groove 544, and the bottom end is connected to the fixed folding rod 6.

[0093] During the rotation of the rotating disk 51, through the transmission of the transmission mechanism 541, the rotating limiting rod 542 connected thereto is driven to rotate. The rotating limiting rod 542 drives the sliding block 543 and the second limiting sliding groove 544 to rotate synchronously. At the same time, the suspension rod 7 is limited by the folding rod sleeve 525, the rotating connecting rod 545 and the rotating limiting rod 542 and will not rotate. The second limiting sliding groove 544 and the first limiting sliding groove 526 rotate synchronously, and the two are in a parallel state or on the same horizontal straight line. When the folding rod sleeve 525 drives the fixed folding rod 6 to move linearly along the first limiting sliding groove 526, the fixed folding rod 6 drives the second limiting sliding groove 544 to move linearly along the sliding block 543 through the rotating connecting rod 545, ensuring the stability of the suspension rod 7 during the movement process, and can also connect and reinforce and limit the suspension rod 7. The transmission mechanism 541 can adopt a belt transmission mechanism, a gear transmission mechanism, etc.

[0096] The suspension rod 7 is reinforced by the provided reinforcing rod 8 to ensure the suspension strength.

[0097] The working principle of the present invention is: The first driving member 31 drives the winding roller 32 to rotate. The winding roller 32 pays out the steel wire rope 33, so that the height of the fixed folding plate 4 decreases, and thus the height of the suspension rod 7 decreases. After the stage lamp is suspended and fixed on the suspension rod 7, the first driving member 31 drives the winding roller 32 to rotate in the reverse direction, winds the steel wire rope 33, so that the height of the fixed folding plate 4 rises, and thus the stage lamp is suspended in the air. When the suspension rod 7 rises, the lower insertion cylinder 342 is inserted into the upper clamping cylinder 341. When the bottom of the upper clamping cylinder 341 abuts against the top of the fixed folding plate 4, the suspension rod 7 stops rising. The upper clamping cylinder 341 and the lower insertion cylinder 342 cooperate to limit the position of the fixed folding plate 4;

[0098] When the position of the stage lighting fixture needs to be adjusted, according to the position to be adjusted of the stage lighting fixture, the driving member three 531 drives the gear two 532 to rotate, the gear two 532 drives the external gear ring 533 to rotate, the external gear ring 533 drives the rotating disk 51 to rotate in the XZ plane, the rotating disk 51 drives the limiting sliding groove one 526 to rotate synchronously, so that the position where the stage lighting fixture is to reach is located on the extending direction of the limiting sliding groove one 526; during the rotation of the rotating disk 51, through the transmission of the transmission mechanism 541, the rotating limiting rod 542 connected thereto is driven to rotate, the rotating limiting rod 542 drives the sliding block 543 and the limiting sliding groove two 544 to rotate synchronously. At the same time, the suspension rod 7 is limited by the folding rod sleeve 525, the rotating connecting rod 545 and the rotating limiting rod 542 and will not rotate. The limiting sliding groove two 544 and the limiting sliding groove one 526 rotate synchronously, and the two are in a parallel state or on the same horizontal straight line;

[0099] The driving member two 521 drives the gear one 522 to rotate, the gear one 522 drives the toothed plate 523 to move, the toothed plate 523 drives the sliding folding rod 524 to move, the sliding folding rod 524 ensures the stability of the toothed plate 523 during movement, the toothed plate 523 drives the folding rod sleeve 525 to move linearly along the limiting sliding groove one 526, the folding rod sleeve 525 drives the fixed folding rod 6 and the suspension rod 7 to move linearly synchronously, thereby adjusting the position of the stage lighting fixture. When the folding rod sleeve 525 drives the fixed folding rod 6 to move linearly along the limiting sliding groove one 526, the fixed folding rod 6 drives the limiting sliding groove two 544 to move linearly along the sliding block 543 through the rotating connecting rod 545, ensuring the stability of the suspension rod 7 during movement.
