Abstract

The present invention relates to the technical field of stage lights, and specifically provides a support device and a stage light for a stage light, including a base and a U-shaped support frame. The U-shaped support frame is rotatably connected to the top of the base. Telescopic support foot mechanisms are symmetrically arranged on the opposite side walls of the base. Two liftable moving wheel mechanisms are symmetrically arranged at the bottom of the base. A driving mechanism connected to the support foot mechanisms and the moving wheel mechanisms is arranged in the inner cavity of the base. When the stage light is moving, the present invention can move through the moving wheel mechanisms, and the support feet are in a contracted state during movement, reducing the floor area of the base and facilitating movement. When the stage light is in use, the moving wheel mechanisms can be raised into the base and the support foot mechanisms can be unfolded for support, increasing the support moment of the support feet, thereby improving the stability of the stage light during use. At the same time, only one set of driving mechanisms can be used to perform two actions, not only reducing the cost but also improving the action efficiency.

Description

Technical Field

[0001] The present invention relates to the technical field of stage lights, and specifically relates to a support device and a stage light for a stage light. Background Art

[0002] Currently, stage lights are lights used in live performances to enhance the on-site visual effects and set off the on-site atmosphere. They include various types of lamp bodies such as laser lights, neon lights, and searchlights. And with the development of social economy, more and more concerts, roadshows and other activities are held, and the holding of these activities all require stage lights to set off the atmosphere. Therefore, a stage light that can be easily moved is needed for use. In order to facilitate movement and carrying, existing stage lights often install moving wheels at the bottom of the stage light to facilitate movement (such as the patent application number: 201721348689.2) or install handles on the side wall of the stage light to facilitate carrying (such as the patent application number: 202220918650.4). When moving wheels are installed at the bottom of the stage light, the moving wheels need to be locked one by one when the stage light is in use, which is time-consuming and laborious and will cause the stage light to be unstable during use. When carrying with a handle, it increases the labor intensity of the staff. For this reason, we have proposed a support device and a stage light for a stage light to be put into use to solve the above problems. Summary of the Invention

[0030] 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 making creative efforts belong to the scope of protection of the present invention.

[0031] Please refer to Figures 1-8 , the present invention provides a technical solution:

[0032] A support device for a stage light, including a base 1 and a U-shaped support frame 2. The U-shaped support frame 2 is rotatably connected to the top of the base 1. A partition board 11 is arranged between the inner cavity side walls of the base 1, and the partition board 11 divides the inner cavity of the base 1 into an upper cavity and a lower cavity;

[0033] On the opposite sides of the base 1, there are symmetrically arranged retractable support foot mechanisms 3. At the bottom of the base 1, there are symmetrically arranged two liftable mobile wheel mechanisms 4. The support foot mechanisms 3 and the mobile wheel mechanisms 4 are both located inside the lower cavity of the base 1. Inside the cavity of the base 1, there is a drive mechanism 5 connected to the support foot mechanisms 3 and the mobile wheel mechanisms 4. The drive mechanism 5 drives the support foot mechanisms 3 to expand and contract while driving the mobile wheel mechanisms 4 to lift. And when the support foot mechanisms 3 extend to the support position, the mobile wheel mechanisms 4 rise into the base 1. When the mobile wheel mechanisms 4 descend to contact the ground, the support foot mechanisms 3 contract to the opposite side walls of the base 1.

[0034] The support foot mechanism 3 includes a fixed block 31 installed at the bottom of the inner cavity of the base 1. The fixed block 31 is rotatably connected through a first lead screw 32. A first threaded sleeve 33 is threadedly connected to the outer wall of the first lead screw 32. One end of the first threaded sleeve 33 away from the first lead screw 32 is vertically connected to a first connecting plate 34. At the opposite ends of one side surface of the first connecting plate 34 away from the first threaded sleeve 33, there are symmetrically connected connecting rods 35. One end of the connecting rod 35 penetrates through the side wall of the base 1 and is connected to a support foot 36. The side wall of the base 1 is provided with a first opening 12 that cooperates with the connecting rod 35.

[0035] Specifically, at the bottom of the inner cavity of the base 1, there is a limit slide rail 37 that is slidably connected to the first connecting plate 34.

[0036] As can be seen from the above description: The limit slide rail can play a role in assisting the support and limiting the sliding of the first connecting plate.

[0037] Specifically, the mobile wheel mechanism 4 includes a second lead screw 41. The second lead screw 41 is rotatably connected to the bottom of the partition 11. A second threaded sleeve 42 is threadedly connected to the outer wall of the second lead screw 41. The bottom of the second threaded sleeve 42 is fixedly connected to a second connecting plate 43. At the opposite ends of the bottom of the second connecting plate 43, there are symmetrically installed mobile wheels 44. The bottom of the base 1 is provided with a second opening that cooperates with the mobile wheels 44.

[0038] As can be seen from the above description: The self-locking function between the lead screw and the threaded sleeve can ensure the stability of the mobile wheels.

[0039] Specifically, the drive mechanism 5 includes a drive motor 51. The drive motor 51 is installed on the partition 11. The outer wall of the output end of the drive motor 51 is respectively connected with a driving sprocket 52 and a driving bevel gear 53. And the driving bevel gear 53 is located below the driving sprocket 52. The driving sprocket 52 is connected to two driven sprockets 55 through a chain 54. And the two driven sprockets 55 are respectively fixedly connected to the outer walls of the two second lead screws 41. The driving bevel gear 53 is meshed with two driven bevel gears 56. And the two driven bevel gears 56 are respectively installed on the outer walls of the two first lead screws 32.

[0040] As can be seen from the above description: The driving motor can drive the driving sprocket and the driving bevel gear to rotate respectively, and drive the moving wheel mechanism and the supporting leg mechanism to move through the driving sprocket and the driving bevel gear respectively, so as to realize the simultaneous movement of the two and improve the efficiency.

[0041] Specifically, two limit posts 45 are symmetrically and slidably connected to opposite ends of the second connecting plate 43, and the limit posts 45 are fixedly connected between the bottom of the partition plate 11 and the bottom of the inner cavity of the base 1. A second spring 46 is sleeved on the outer wall of the limit post 45, and the second spring 46 is located between the second connecting plate 43 and the partition plate 11.

[0042] As can be seen from the above description: The stability of the up-and-down lifting of the second connecting plate can be ensured by the action of the limit post and the second spring, and the second spring can provide a certain supporting force to ensure the balance of both ends of the second connecting plate.

[0043] Specifically, the supporting leg 36 includes a fixed sleeve 361, the fixed sleeve 361 is installed at the top of the connecting rod 35, a slider 362 is slidably connected between the side walls of the inner cavity of the fixed sleeve 361, a support column 363 is fixedly connected to the bottom of the slider 362, and the support column 363 penetrates through the inner cavity of the connecting rod 35. A first spring 364 is connected between the top of the slider 362 and the top of the inner cavity of the fixed sleeve 361.

[0044] As can be seen from the above description: The first spring is arranged inside the supporting leg, so that it can play a buffering role, thereby ensuring the stability of the stage light during operation.

[0045] Specifically, the first opening 12 is adapted to the supporting leg 36, a first inclined surface 13 is provided at the bottom of the first opening 12, a second inclined surface 365 is provided at the bottom of the support column 363 and is matched with the first inclined surface 13. When the supporting leg 36 contracts, the support column 363 is compressed through the cooperation of the first inclined surface 13 and the second inclined surface 365 and is clamped into the first opening 12.

[0046] As can be seen from the above description: When the supporting leg contracts, the supporting leg can be clamped into the first opening, thereby further reducing the area of the base and facilitating movement in a narrow space.

[0047] Specifically, the inside of the support column 363 is a hollow structure, and the bottom of the support column 363 is communicated with a suction cup 366. The top of the support column 363 is communicated with a vacuum suction pipe 367 made of a soft material. One end of the vacuum suction pipe 367 away from the suction cup 366 passes through the top of the fixed sleeve 361 and is connected with a micro vacuum pump, and the micro vacuum pump is arranged in the lower cavity of the base 1.

[0048] As can be seen from the above description: When the supporting leg is supporting, the suction cup can be evacuated through the micro vacuum pump and the vacuum suction pipe, so that the suction cup firmly adsorbs on the ground and ensures the stability of the support of the supporting leg.

[0049] Specifically, a spring button switch that cooperates with the micro vacuum pump is provided on the inner wall of the base 1. When the support foot mechanism 3 extends to the support position, the first connecting plate 34 abuts against the spring button switch and presses the spring button switch.

[0050] As can be seen from the above description: It is possible to achieve automatic opening and closing of the micro vacuum pump, thereby avoiding the use of complex circuits for control, simplifying the equipment program, and reducing the equipment cost.

[0051] A stage light includes a support device. A stage light body 6 is installed on the U-shaped support frame 2 of the support device, and the stage light body 6 is rotatably connected to the U-shaped support frame 2.

[0052] Please refer to Figures 1-5 Figures 7-8: An embodiment of the present invention is as follows:

[0053] As Figure 8 shown: A stage light includes a support device and a stage light body 6. The installation method between the stage light body 6 and the U-shaped support frame 2 on the support device and the operation method of the stage light body 6 are both prior arts and will not be described in detail in this embodiment;

[0054] As Figure 1 and 2 shown, the support device includes a base 1 and a U-shaped support frame 2. The U-shaped support frame 2 is rotatably connected to the top of the base 1. A partition 11 is provided between the side walls of the inner cavity of the base 1. The partition 11 divides the inner cavity of the base 1 into an upper cavity and a lower cavity;

[0055] As Figure 4 shown, the support foot mechanism 3 includes a fixed block 31 installed at the bottom of the inner cavity of the base 1. The fixed block 31 is rotatably connected through a first screw rod 32. A first threaded sleeve 33 is threadedly connected to the outer wall of the first screw rod 32. One end of the first threaded sleeve 33 away from the first screw rod 32 is vertically connected to a first connecting plate 34. Opposite ends of one side surface of the first connecting plate 34 away from the first threaded sleeve 33 are symmetrically connected with connecting rods 35. One end of the connecting rod 35 penetrates through the side wall of the base 1 and is connected to a support foot 36. The side wall of the base 1 is provided with a first opening 12 that cooperates with the connecting rod 35. A limit slide rail 37 that slidably connects with the first connecting plate 34 is provided at the bottom of the inner cavity of the base 1;

[0056] As Figure 7As shown in the figure, the support foot 36 includes a fixed sleeve 361 which is installed at the top of the connecting rod 35. A slider 362 is slidably connected between the inner cavity side walls of the fixed sleeve 361. A support column 363 is fixedly connected to the bottom of the slider 362, and the support column 363 penetrates through the inner cavity of the connecting rod 35. A first spring 364 is connected between the top of the slider 362 and the top of the inner cavity of the fixed sleeve 361. The inside of the support column 363 is a hollow structure, and the bottom of the support column 363 communicates with a suction cup 366. The top of the support column 363 communicates with a flexible vacuum suction pipe 367. One end of the vacuum suction pipe 367 away from the suction cup 366 passes through the top of the fixed sleeve 361 and is connected to a micro vacuum pump, and the micro vacuum pump is arranged in the lower cavity of the base 1. A spring button switch which cooperates with the micro vacuum pump is arranged on the inner wall of the base 1. When the support foot mechanism 3 extends to the support position, the first connecting plate 34 abuts against the spring button switch and presses the spring button switch.

[0057] As Figure 3 shown in the figure, the moving wheel mechanism 4 includes a second lead screw 41 which is rotatably connected to the bottom of the partition plate 11. A second threaded sleeve 42 is threadedly connected to the outer wall of the second lead screw 41. A second connecting plate 43 is fixedly connected to the bottom of the second threaded sleeve 42. Two moving wheels 44 are symmetrically installed at the opposite ends of the bottom of the second connecting plate 43. A second opening which cooperates with the moving wheels 44 is formed at the bottom of the base 1. Two limiting columns 45 are symmetrically and slidably connected to the opposite ends of the second connecting plate 43, and the limiting columns 45 are fixedly connected between the bottom of the partition plate 11 and the bottom of the inner cavity of the base 1. A second spring 46 is sleeved on the outer wall of the limiting column 45, and the second spring 46 is located between the second connecting plate 43 and the partition plate 11.

[0058] As Figure 4 shown in the figure, the driving mechanism 5 includes a driving motor 51 which is installed on the partition plate 11. The outer wall of the output end of the driving motor 51 is respectively connected with a driving sprocket 52 and a driving bevel gear 53, and the driving bevel gear 53 is located below the driving sprocket 52. The driving sprocket 52 is connected to two driven sprockets 55 through a chain 54, and the two driven sprockets 55 are respectively fixedly connected to the outer walls of the two second lead screws 41. The driving bevel gear 53 is meshed with two driven bevel gears 56, and the two driven bevel gears 56 are respectively installed on the outer walls of the two first lead screws 32.

[0059] The specific application of the above stage light is as follows:

[0060] When the stage light needs to be moved, the driving motor 51 is started. The driving motor 51 drives the driving sprocket 52 and the driving bevel gear 53 to rotate respectively. The driving sprocket 52 drives two driven sprockets 55 to rotate through the chain 54, thereby driving two second lead screws 41 to rotate simultaneously, so that the second threaded sleeve 42 and the second connecting plate 43 descend under the limiting action of the limiting column 45, so that the moving wheels 44 (the moving wheels adopt universal wheels) pass through the second opening at the bottom of the base 1 and contact the ground to support the stage light. At the same time, the driving bevel gear 53 drives two groups of driven bevel gears 56 to rotate, so that the two first lead screws 41 drive the two first threaded sleeves 33 and the first connecting plate 34 to slide close to each other under the limiting action of the limiting slide rail 37, so that the first connecting plate 34 disengages from the spring button switch, causing the spring button switch to reset and close the micro vacuum pump, thereby canceling the vacuum suction of the suction cup 366, enabling the support feet 36 and the connecting rod 35 to contract along the side wall of the base 1 with the first connecting plate 34, thereby reducing the overall area of the base 1, and then moving through the moving wheels 44;

[0061] When the stage light is in use, the driving motor 51 (the driving motor 51 is a two-way motor) is started. The driving motor 51 drives the driving sprocket 52 and the driving bevel gear 53 to rotate respectively. Among them, the driving sprocket 52 drives the moving wheels 44 to rise and pass through the second opening of the base 1 into the interior of the base 1. At the same time, the driving bevel gear 53 drives two groups of support feet 36 to move in opposite directions, so as to extend. And after the moving wheels 44 rise to a certain height, the suction cup 366 at the bottom of the support feet 36 contacts the ground, enabling the support feet 36 to play a supporting role. And when the support feet 36 extend to the supporting position, the first connecting plate 34 contacts and presses the spring button switch inside the base 1, thereby turning on the micro vacuum pump. Through the micro vacuum pump and the vacuum suction pipe 367, the suction cup 366 is vacuum-sucked, so that the suction cup 366 firmly adsorbs the ground, ensuring the stability of the stage light during use (the structure when the support feet support is as Figure 3 shown);

[0062] In this embodiment, the upper cavity inside the base 1 is provided with a first power mechanism for the U-shaped support frame 360 to rotate and corresponding controller and other structures, and they are all prior arts and not improved in this embodiment, so they are not described in detail in this embodiment;

[0063] In this embodiment, both side walls of the U-shaped support frame 2 are provided with a second power mechanism for the stage light body 6 to flip and corresponding controller and other structures, and they are all prior arts and not improved in this embodiment, so they are not described in detail in this embodiment;

[0064] In this embodiment, when the stage light body 6 flips and jitters, the first spring 364 inside the support foot 36 can play a role in buffering and shock absorption, further improving the stability of the stage light during operation.
