DETAILED DESCRIPTION

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0052] In the embodiment of the present invention, please refer to Figures 1 to 7 A stage lighting fixture suspension device comprises a mounting plate 1 and a suspension rod 7, wherein the mounting plate 1 is provided with a mounting hole, the suspension rod 7 is located at the bottom of the mounting plate 1, and the suspension rod 7 is used to suspend the stage lighting fixture, and further comprises:

[0053] A connecting plate 2 is connected to the bottom of the mounting plate 1;

[0054] A Y-axis lifting mechanism 3, one end of which is connected to the connecting plate 2, and is used to drive the suspension rod 7 to move longitudinally in the Y-axis direction;

[0058] The rotating disk 51 is rotatably connected to the top of the fixed folding plate 4;

[0059] A power adjustment assembly 52, one end of which is connected to the rotating disk 51, and the other end of which is rotatably connected to the fixed folding rod 6, for driving the suspension rod 7 to move in the XZ plane;

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

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

[0062] The height of the hanging rod 7 is lowered by the Y-axis lifting mechanism 3. After the stage lamp is hung on the hanging rod 7, the hanging rod 7 is raised by the Y-axis lifting mechanism 3, so that the stage lamp is suspended in the air. When the position of the hanging lamp needs to be adjusted, the direction adjustment component 53 drives the rotating disk 51 to rotate according to the direction in which the hanging lamp is to move, and then drives the power adjustment component 52 and the motion stabilization component 54 to rotate. The direction of the hanging rod 7 remains unchanged, and the power adjustment component 52 drives the hanging rod 7 to move in the XZ plane, so as to adjust the position of the stage lamp, and the motion stabilization component 54 ensures the stable movement of the hanging rod 7.

[0068] When the suspension rod 7 is lowered, the driving member 31 drives the winding roller 32 to rotate, and the winding roller 32 unwinds the wire rope 33, so that the height of the fixed folding plate 4 is lowered, thereby lowering the height of the suspension rod 7. After the stage lamp is hung and fixed on the suspension rod 7, the driving member 31 drives the winding roller 32 to rotate in the opposite direction, and winds the wire rope 33, so that the height of the fixed folding plate 4 is raised, thereby hanging the stage lamp in the air, and the limiting component 34 limits the fixed folding plate 4 to prevent the fixed folding plate 4 from shifting when the position of the suspension rod 7 changes.

[0072] In the initial state, the lower insert cylinder 342 is inserted into the upper cylinder 341. When the hanging rod 7 is lowered, the lower insert cylinder 342 descends with the fixed folding plate 4 and separates from the upper cylinder 341. When the hanging rod 7 rises, the lower insert cylinder 342 is inserted into the upper cylinder 341. When the bottom of the upper cylinder 341 abuts against the top of the fixed folding plate 4, the hanging rod 7 stops rising.

The top of the lower insert cylinder 342 is small at the top and large at the bottom, and the bottom of the upper cylinder 341 is small at the top and large at the bottom, which facilitates the insertion of the lower insert cylinder 342 into the upper cylinder 341.

The bearing sleeve is rotatably connected to the fixed folding rod 6.

[0081] When the position of the stage lighting fixture needs to be adjusted, the second driving member 521 drives the first gear 522 to rotate, the first gear 522 drives the tooth plate 523 to move, the tooth plate 523 drives the sliding folding rod 524 to move, the sliding folding rod 524 ensures the stability of the tooth plate 523 during movement, the tooth plate 523 drives the folding rod sleeve 525 to move linearly along the limiting slide groove 1 526, and the folding rod sleeve 525 drives the fixed folding rod 6 and the hanging rod 7 to move linearly synchronously, thereby adjusting the position of the stage lighting fixture. The second driving member 521 can be a stepping motor, a servo motor, etc.

The driving member 3 531 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 motion stabilization component 54 includes:

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

[0097] The working principle of the present invention is as follows: 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 is lowered, thereby lowering the height of the hanging rod 7. After the stage lamp is hung and fixed on the hanging rod 7, the driving member 31 drives the winding roller 32 to rotate in the opposite direction, and winds the steel wire rope 33, so that the height of the fixed folding plate 4 is raised, thereby hanging the stage lamp in the air. When the hanging rod 7 rises, the lower insert cylinder 342 is inserted into the upper clamp cylinder 341. When the bottom of the upper clamp cylinder 341 abuts against the top of the fixed folding plate 4, the hanging rod 7 stops rising, and the upper clamp cylinder 341 and the lower insert 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, the driving member 3 531 drives the gear 2 532 to rotate, the gear 2 532 drives the outer gear ring 533 to rotate, the outer gear ring 533 drives the rotating disk 51 to rotate in the XZ plane, and the rotating disk 51 drives the limiting slide groove 1 526 to rotate synchronously, so that the position to be reached by the stage lighting fixture is located in the extension direction of the limiting slide groove 1 526; during the rotation of the rotating disk 51, the rotating limiting rod 542 connected thereto is driven to rotate through the transmission of the transmission mechanism 541, and the rotating limiting rod 542 drives the sliding block 543 and the limiting slide groove 2 544 to rotate synchronously. At the same time, the hanging rod 7 will not rotate under the limitation of the folding rod sleeve 525, the rotating connecting rod 545 and the rotating limiting rod 542, and the limiting slide groove 2 544 and the limiting slide groove 1 526 rotate synchronously, and the two are in a parallel state or on the same horizontal straight line;

[0099] Driving member 2 521 drives gear 1 522 to rotate, gear 1 522 drives tooth plate 523 to move, tooth plate 523 drives sliding folding rod 524 to move, sliding folding rod 524 ensures the stability of tooth plate 523 during movement, tooth plate 523 drives folding rod sleeve 525 to move linearly along limiting slide groove 1 526, folding rod sleeve 525 drives fixed folding rod 6 and hanging rod 7 to move linearly synchronously, thereby adjusting the position of stage lighting fixtures, when folding rod sleeve 525 drives fixed folding rod 6 to move linearly along limiting slide groove 1 526, fixed folding rod 6 drives limiting slide groove 2 544 to move linearly along sliding block 543 by rotating connecting rod 545, thereby ensuring the stability of hanging rod 7 during movement.
