The base 501 has a groove for the unlocking part 21 to slide up and down.

[0035] Specifically, the connecting rods 6 located on both sides of the longitudinal groove 112 have a second inclined surface 22 on the opposite side end face. The second inclined surface 22 is located on the top of the connecting rod 6 and is used to abut against the side wall of the opening 16.

[0036] Specifically, a pneumatic telescopic cylinder is provided inside the buffer trough 19. One end of the pneumatic telescopic cylinder is fixedly connected to the bottom of the base plate 20, and the other end is fixedly connected to the inner wall of the bottom of the buffer trough 19.

[0037] Specifically, a roller 24 is rotatably provided at one end of the locking plate 14 near the groove.

[0038] Specifically, iron plates 26 and magnetic attractors 25 are embedded in both ends of the connecting unit 7011, and adjacent guide groove units are fixed to each other by magnetic attractors 25 and iron plates 26.

[0039] Specifically, the lifting rod 502 has sockets 30 on both sides, and the base 501 has screw holes at the bottom corresponding to the sockets 30. The screw holes are threaded with guide rods 29. The lifting rod 502 is sleeved on the guide rods 29 through the sockets 30 and forms a sliding connection. The bottom ends of both sides of the base 501 extend downward, and the downward extension of the base 501 has slots for the two ends of the connecting plate to be inserted.

[0040] A specific application example of this embodiment is as follows:

[0041] Reference Figure 1As shown, the system includes a truss, which consists of columns 1 and a crossbeam 2 installed on the top of the columns 1. The stage lights are fixed to the steel pipes of the crossbeam 2 by light hooks. On small stages, the columns 1 and crossbeam 2 are fixedly spliced ​​together and can be erected directly after the stage lights are installed. On larger stages, the lifting and lowering of the crossbeam 2 is achieved by the cooperation of the square sleeve with the columns 1, and then by multiple people pulling the hoist chain to lift and lower the crossbeam 2. The above is the existing technology, so it will not be described in detail.

[0042] Reference Figure 2 , 3 The crossbeam 2 includes an outer frame 4 and an inner frame 5 fixed to the outer frame 4. The inner frame 5 includes a base 501 fixed to the outer frame 4 and a lifting rod 502 for mounting the lamp hook. The lifting rod 502 is located below the base 501. The base 501 contains a drive assembly 7 for driving the lifting rod 502 to rise and fall. The top of the lifting rod 502 has a connecting rod 6 connected to the base 501. The base 501 contains a fixing member for fixing the connecting rod 6. When the stage lamp body 3 rises to its highest position via the lifting rod 502 (e.g., Figure 3 As shown, the connecting rod 6 is inserted into the base 501 and secured by a fastener.

[0043] Reference Figure 3 , 4 The drive assembly 7 includes a symmetrically arranged chain connection part 701, a motor 702, and a bidirectional lead screw 703 fixed to the output end of the motor 702. The chain connection part 701 is composed of multiple sets of interconnected connecting units 7011. Adjacent connecting units 7011 are hinged together by hinges 8. The two ends of the connecting unit 7011 are provided with recesses for accommodating the hinges 8. The use of concealed hinges 8 for connection allows the two connecting units 7011 to fit together when they are spliced, which helps to reduce the gap at the splice of adjacent connecting units 7011 and improves the stability of the chain connection part 701 when pulling the lifting rod 502.

[0044] Reference Figure 3 , 4The connecting unit 7011 at one end of the chain connection 701 is equipped with a slider 9, and the connecting unit 7011 at the other end is fixed to the lifting rod 502. The slider 9 is sleeved on the bidirectional lead screw 703 and forms a threaded connection with the bidirectional lead screw 703. The base 501 is provided with a sliding groove 10 for the slider 9 to slide and a T-slot 11 for the connecting unit 7011 to slide. The sliding groove 10 and the T-slot 11 are interconnected. When the lifting rod 502 rises to its highest position, the sliders 9 on both sides are located at the two ends of the sliding groove 10, and are driven by the motor 702. The rotation of the bidirectional lead screw 703 can drive the two sliders 9 to slide towards each other or away from each other, thereby causing the two chain connecting parts 701 to slide in the T-slot 11 and controlling the length of the bottom end of the chain connecting part 701 extending out of the T-slot 11 to control the lifting rod 502. In the initial state, the two chain connecting parts 701 are partially located outside the T-slot 11 and connected to the top of the lifting rod 502, ensuring that the two chain connecting parts 701 form a Y-shape, making the extension and retraction of the bottom end of the two chain connecting parts 701 into the T-slot 11 more stable.

[0045] Reference Figure 3 , 4 The T-slot 11 includes a transverse groove 111 for the horizontal sliding of the connecting unit 7011, and a longitudinal groove 112 for the longitudinal sliding of the connecting units 7011 of the chain connecting parts 701 on both sides after they are in contact. The front and rear width of the slide groove 10 is smaller than the front and rear width of the T-slot 11, so that the connecting unit 7011 will not be lifted into the slide groove 10 due to mutual squeezing force when the slider 9 drives the connecting unit 7011 to slide. The longitudinal groove 112 makes the connecting units 7011 on the chain connecting parts 701 on both sides contact each other and extend stably downward, thus playing a guiding role.

[0046] Reference Figure 4 , 5 Multiple sets of connecting rods 6 are provided along the length of the lifting rod 502. The base 501 is provided with slots 12 for inserting the connecting rods 6. The base 501 is provided with a sliding groove 13 that is connected to the slots 12. The fixing component includes a locking plate 14 that is horizontally slidably disposed in the sliding groove 13. The end faces of the connecting rods 6 located on both sides of the longitudinal groove 112 that are far apart from each other are provided with a bayonet 15. The locking plate 14 is provided with multiple through holes 16 for the connecting rods 6 to pass through. A spring 17 is provided on one side of the sliding groove 13 to drive the side wall of the through hole 16 to engage with the bayonet 15. When the lifting rod 502 is raised to the highest position, each set of connecting rods 6 is inserted into the slot 12. The springs 17 on both sides will push the locking plates 14 on both sides to slide towards the side that is close to each other, so that the side wall of the through hole 16 engages with the bayonet 15 of the connecting rod 6, thereby forming a snap-fit ​​on the connecting rod 6, so that the weight of the lifting rod 502 and the stage light is distributed and supported.

[0047] Reference Figure 4 , 5A fixing block 18 is located at the top of the lifting rod 502 directly below the longitudinal groove 112. A buffer groove 19 is located within the fixing block 18, and a base plate 20 slides vertically within the buffer groove 19. The bottom ends of the connecting units 7011 at one end of the chain-type connecting parts 701 on both sides are fixedly connected to the base plate 20. One set of connecting units 7011 in the chain-type connecting parts 701 is provided with an unlocking part 21 that drives the fixing member to disengage from the connecting rod 6. In this embodiment, the unlocking part 21 is a set of isosceles trapezoidal blocks. The two sides of the unlocking part 21 are provided with inclined surfaces for abutting against the locking plate 14 and driving the side wall of the passage 16 to disengage from the bayonet 15. When the lifting rod 502 rises to its highest point, the connecting unit 7011 with the unlocking part 21... Located directly above the locking plate 14, when the chain connecting parts 701 on both sides move downward in the longitudinal groove 112, the inclined surface of the unlocking part 21 will push the locking plate 14 to slide away from the longitudinal groove 112, causing the side wall of the through 16 to disengage from the latch 15, thereby allowing the connecting rod 6 to slide out of the slot 12; wherein, the buffer groove 19 can provide a certain space for the chain connecting part 701 to slide downward, so that the chain connecting part 701 slides a certain distance before the locking plate 14 disengages from the connecting rod 6, avoiding jamming; the base 501 is provided with a groove for the unlocking part 21 to slide up and down, the width of the groove is smaller than the width of the longitudinal groove 112, so that the connecting unit 7011 slides stably.

[0048] Reference Figure 4 The connecting rods 6 located on both sides of the longitudinal groove 112 have a second inclined surface 22 on their opposite ends. The second inclined surface 22 is located on the top of the connecting rod 6 and is used to abut against the side wall of the through 16. When the lifting rod 502 rises and the connecting rod 6 is inserted into the slot 12, the second inclined surface 22 will abut against the locking plate 14 before the unlocking part 21, so as to avoid the unlocking part 21 contacting the locking plate 14 first and causing jamming. The second inclined surface 22 abuts against the side wall of the through 16 and drives the locking plate 14 to slide away from the longitudinal groove 112. After the connecting rod 6 slides to the top, the locking plate 14 will automatically lock into the slot 15 under the action of the spring 17.

[0049] Reference Figure 4 The buffer groove 19 is equipped with a pneumatic telescopic cylinder. One end of the pneumatic telescopic cylinder is fixedly connected to the bottom of the base plate 20, and the other end is fixedly connected to the inner wall of the bottom of the buffer groove 19. After the chain connection part 701 drives the base plate 20 to move a certain distance in the buffer groove 19 and the locking plate 14 disengages from the locking rod 6, the pneumatic telescopic cylinder can prevent the lifting platform from suddenly falling down a certain distance, which would cause instability, and make the chain connection part 701 more stable when it drives the lifting rod 502 to move down.

[0050] Reference Figure 4 , 6A roller 24 is rotatably provided at one end of the locking plate 14 near the groove. Generally, the roller 24 is located outside the locking plate 14, which can reduce the friction with the locking plate 14 when the chain connection 701 moves downward.

[0051] Reference Figure 4 The two ends of the connecting unit 7011 are respectively embedded with iron plates 26 and magnets 25. Adjacent guide groove units are fixed to each other by magnets 25 and iron plates 26. The top of the connecting unit 7011 of the chain connecting part 701 on one side is provided with a second magnet 27, and the top of the connecting unit 7011 of the chain connecting part 701 on the other side is provided with an iron plate 28. When the two chain connecting parts 701 on both sides are in contact and move outside the T-slot 11, the cooperation between the magnets 25 and iron plates 26 and the cooperation between the second magnets 27 and the plates 26 makes the parts of the chain connecting parts 701 on both sides outside the T-slot 11 more stable and maintain a vertical downward state. When the lifting rod 502 is driven to rise and fall, it is more stable and less prone to shaking.

[0052] Reference Figure 2 , 5 The lifting rod 502 has sockets 30 on both sides. The base 501 has screw holes at the bottom corresponding to the sockets 30. The screw holes are threaded with guide rods 29. The lifting rod 502 is sleeved on the guide rods 29 through the sockets 30 and forms a sliding connection. The bottom ends of both sides of the base 501 extend downward. The downward extension of the base 501 has slots for the two ends of the connecting plate to be inserted. When it is necessary to lower the lifting rod 502 to maintain the stage light body 3, the guide rods 29 can be removed. The guide rods 29 pass through the sockets 30 through the lifting rod 502 and are threaded into the screw holes, making the lifting rod 502 more stable when it descends. After the lifting rod 502 is raised to the top and fixed, the guide rods 29 can be removed to avoid affecting the use of the stage space.

[0053] The implementation principle of a stage lamp with a lifting structure in this application embodiment is as follows:

[0054] When stage lights need maintenance, the guide rod 29 can be threaded into the screw hole. The drive motor 702 drives the bidirectional lead screw 703 to rotate. Under the action of the slider 9, the two chain connecting parts 701 on both sides move downwards at the contact part of the longitudinal groove 112, thereby driving the lifting rod 502 to fall to the lower end, so that the stage light body 3 can be maintained. Since the stage light body 3 is located at a lower position, the maintenance items of the stage light body 3 can be carried out directly without disassembly, which greatly improves the convenience of maintenance. After maintenance, the motor 702 reverses to drive the chain connecting part 701 to slide into the T-slot 11, thereby driving the lifting rod 502 to rise to the highest position. Then, the guide rod 29 can be removed to complete the maintenance of the stage light body 3.
