Description

Technical Field

[0001] The invention relates to the field of stage lighting, in particular to a stage lighting which can be conveniently switched and extended. Background Art

[0002] Stage lighting is one of the means of stage art modeling. It requires the use of stage lighting equipment, such as lighting fixtures, slides, wash lights, lighting control systems, etc. It displays the environment, creates the atmosphere, highlights the central characters, creates a sense of stage space and time, shapes the external image of the stage performance, and provides necessary lighting effects as the plot develops and changes.

[0003] A Chinese patent with related announcement number CN108266706A discloses a stage lighting mobile device, including a travel track; a support base supported by the travel track and capable of moving along the travel track, the support base being used to install a lamp holder; a rack arranged on the travel track, the extension direction of the rack being consistent with the extension direction of the travel track; a gear arranged on the support base and meshing with the rack; and a power mechanism arranged on the support base and used to drive the gear to rotate.

[0004] With regard to the above-mentioned related technologies, in order to achieve the purpose of moving on the track, the existing stage lights need to install a driving motor in the base of each stage light, which has a high cost for realizing the movement of the stage lights. It is also easy to cause greater pressure on the track support structure due to the extra weight generated by the additional driving motor installed in the base of each stage light. In addition, since the existing stage lights cannot be switched on the straight track due to mutual obstruction, when it is necessary to switch the position of each stage light, the stage light that needs to be adjusted can only be removed and then reinstalled. Switching the position of the stage lights requires a lot of time and labor costs. In summary, the cost of realizing the switching and extension of stage illumination lights along the track by the existing technology is high. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a stage lighting that can be easily switched and extended, so as to solve the technical problem of high cost in the prior art of switching and extending the stage lighting along the track.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a stage lighting that can be conveniently switched and extended, comprising a slide rail, one side of the slide rail is connected to at least one offset platform, and the other side is fixedly connected to a driving platform, two driving chains with opposite movement directions are arranged in the driving platform along the length direction, and also includes a moving platform, the moving platform is used to install the stage lighting and can slide in the slide rail, the moving platform is installed with an insert structure that cooperates with the two driving chains respectively in the direction of the driving platform, and also includes a slide plate, which can push the moving platform onto the offset platform.

[0007] By adopting the above technical solution, when the plug-in structure is inserted into the corresponding driving track, the driving chain is used to drive each moving stage, and there is no need to install a driving motor on the moving stage. At the same time, a dislocation table is set on one side of the slide rail, and the moving stage moved to the corresponding position of the dislocation table is temporarily moved to the dislocation table by using a telescopic rod, so that it is dislocated with other moving stages on the track, thereby conveniently realizing the switching of the arrangement and combination of stage lights on the track, and realizing the convenient switching and extension of stage lights at a relatively low cost.

[0009] As a preferred embodiment, there is no need to install a drive motor on the moving stage. When the moving stage needs to be moved, it is only necessary to operate the drive chain. The moving stage that needs to be moved can be driven by the drive chain by rotating the plug plate to insert the corresponding plug into the drive chain, thereby greatly reducing the cost of moving the stage lighting.

[0010] The present invention is further configured as follows: a fixed plate is fixedly connected to a side of the moving platform facing the driving platform, at least one control box is installed on the fixed plate, the plug plate is slidably connected to the control box, and a friction plate for contacting the driving platform is arranged between the first plug block and the second plug block, a fixed iron sheet is fixedly connected to the back side of the plug plate, an electromagnet for attracting the fixed iron sheet is installed in the control box, a spring in a compressed state is installed between the plug plate and the inner wall of the control box, one side of the plug plate is fixedly connected to the rotating shaft of the bidirectional motor, and the bidirectional motor is slidably installed on the outer wall of the control box, when the first plug block is inserted to cooperate with the first driving chain, the second plug block and the friction plate are both away from the driving platform, and when the second plug block is inserted to cooperate with the second driving chain, the first plug block and the friction plate are both away from the driving platform.

[0011] Preferably, the friction force generated by the contact between the friction plate and the driving platform plays a role in preventing the moving platform from sliding.

[0012] The present invention is further configured such that the length of the offset platform is greater than that of the moving platform, a groove is provided along the length direction on one side of the moving platform away from the driving platform, a protrusion that can slide in the groove is fixedly connected to the slide board, a telescopic rod is fixedly installed on the bottom surface of the slide rail, the telescopic end of the telescopic rod is fixedly connected to the slide board, and the offset platform is provided with a slide board track for sliding the part of the slide board connected to the telescopic rod.

[0013] Preferably, when the telescopic rod is extended or retracted, the convex head on the slide plate can be used to drive the moving platform to slide along the retracting direction of the telescopic rod.

[0014] The present invention is further configured such that a conductive track is provided on one side of the slide rail close to the driving platform along the length direction, and a conductive head for matching the conductive track is fixed on the side of the moving platform.

[0015] Preferably, the moving platform uses a conductive head in cooperation with a conductive track to supply power to electrical equipment on the moving platform.

[0016] The present invention is further configured such that a roller is rotatably connected to the bottom surface of the moving platform, and the rolling direction of the roller is the same as the moving direction of the moving platform.

[0017] Preferably, the roller can effectively reduce the friction resistance when the platform moves along the direction of the slide rail.

[0018] The present invention is further configured such that two control boxes parallel to each other are installed on the fixed plate, the plug plates in the control boxes are fixedly connected by a transmission rod, the control box is provided with a transmission rod sliding groove for the transmission rod to slide along the sliding direction of the plug plates, and one end of the transmission rod is connected to the output end of the bidirectional motor.

[0019] Preferably, two groups of control boxes can further ensure that the platform can move smoothly.

[0020] The present invention is further configured such that one end of the slide rail provided with the driving platform is lower than one end provided with the offset platform.

[0021] As a preferred embodiment, it is convenient for the moving platform to be reset from the offset platform to the inside of the slide rail.

[0022] The present invention is further configured such that the moving platform and the stage lighting located on the offset platform will not interfere with other moving platforms and the stage lighting.

[0023] As a preferred embodiment, it is prevented that the moving stage or the stage lighting on the moving stage collides with other moving stages or the stage lighting on the moving stage after being moved to the offset stage.

[0024] In summary, the present invention mainly has the following beneficial effects:

[0025] 1. The present invention uses two drive chains moving in opposite directions to cooperate with the plug-in structure on the moving stage. When the plug-in structure is inserted into the corresponding driving track, the drive chain is used to drive each moving stage, and there is no need to install a driving motor on the moving stage. At the same time, a dislocation platform is set on one side of the slide rail, and the moving stage moved to the corresponding position of the dislocation platform is temporarily moved to the dislocation platform by using a telescopic rod, so that it is dislocated with other moving stages on the track, thereby conveniently realizing the switching of the arrangement and combination of stage lights on the track, and realizing the convenient switching and extension of stage lights at a relatively low cost.

[0026] 2. The present invention controls the movement and rotation of the plug plate through an electromagnet and a bidirectional motor. Under normal circumstances, the friction plate on the plug plate contacts the driving platform to position the moving platform. When the position of the moving platform needs to be adjusted, the electromagnet is energized and the bidirectional motor rotates, so that one of the plug-in structures of the plug plate is inserted into the corresponding drive chain, thereby realizing the convenient movement of the moving platform. When the moving platform needs to stop sliding, the bidirectional motor is reset and the electromagnet is powered off. The plug plate moves toward the driving platform under the action of the spring elastic force, so that the friction plate and the driving platform are restored to contact, thereby preventing the moving platform from continuing to slide due to its own inertia, thereby improving the accuracy of the moving platform movement.

[0027] 3. The present invention sets the slide rail as an inclined structure so that the side of the slide rail provided with the conductive track is lower than the side connected with the misalignment platform. In the resetting process after the dislocation movement of the moving platform, it is convenient to insert the conductive head on the moving platform more accurately into the conductive track to better restore the power supply to the moving platform. At the same time, the rollers arranged on the bottom surface of the moving platform can also further improve the stability of the moving platform during movement and reduce the friction resistance of the moving platform in the slide rail.

[0028] 4. The present invention uses an inclined slide structure so that both ends of the slide can be connected to the side parts of the slide rail, which can limit the position of the moving platform when the slide does not move, and effectively prevent the insert block from being separated from the drive chain when the moving platform passes the corresponding position of the slide.

[0029] 5. The present invention arranges a groove along the moving direction on the edge of the moving stage, and fixes a convex head that can slide and fit in the groove on the slide. When the telescopic rod is not extended, the convex head will not affect the movement of the moving stage. After the moving stage moves to the corresponding position of the offset stage, the telescopic rod is extended to bring the moving stage to the offset stage through the convex head on the slide board and the groove of the moving stage, so that the moving stage and other moving stages on the slide rail are mutually offset, which is convenient for switching the arrangement order of the stage lights.

[0043] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0044] The following describes an embodiment of the present invention based on its overall structure.

[0045] First embodiment:

[0046] A stage lighting that can be easily switched and extended, please refer to Figure 1-11, including a slide rail 1, one side of the slide rail 1 is connected to at least one offset platform 4, and the other side is fixedly connected to a driving platform 3. Specifically, the connection position and the number of the offset platforms 4 can be adaptively adjusted according to the number and size of the stage lights on the slide rail 1. In the present embodiment, the offset platform 4 is arranged at a position close to the end of the slide rail 1, and the number is one. Two drive chains with opposite movement directions are arranged in the driving platform 3 along the length direction. Specifically, the ends of the two drive chains with opposite movement directions are provided with drive motors to make the two drive chains move in a circular motion. The two drive chains with opposite movement directions play a role in pushing the moving platform 2 to slide forward or reversely along the slide rail 1. The moving platform 2 also includes a moving platform 2, which is used to install the stage light and can slide in the slide rail 1. The top surface of the moving platform 2 is provided with a mounting surface for installing the stage light. The moving platform 2 is installed with a plug-in structure respectively cooperating with the two drive chains in the direction of the driving platform 3. The moving platform 2 also includes a slide plate 6, which can push the moving platform 2 onto the offset platform 4 to achieve the replacement of adjacent stage lights.

[0047] In the above embodiments, please refer to Figure 6-9 The driving platform 3 is provided with a first driving chain 301 and a second driving chain 302 which are parallel to each other along the length direction. The moving platform 2 is rotatably connected with an insert plate 9. The top and bottom ends of the insert plate 9 are respectively fixedly connected with a first insert block 902 for cooperating with the first driving chain 301 and a second insert block 903 for cooperating with the second driving chain 302. Specifically, when the first insert block 902 is plugged into and matched with the first driving chain 301, the moving platform 2 is driven by the moving first driving chain 301 to slide forward on the slide rail 1. When the second insert block 903 is plugged into and matched with the second driving chain 302, the moving platform 2 is driven by the moving second driving chain 302 to slide reversely on the slide rail 1. There is no need to install a driving motor on the moving platform 2. When the moving platform 2 needs to be moved, it only needs to make the driving chain work. The moving platform 2 that needs to be moved can insert the corresponding insert block into the driving chain by rotating the insert plate 9, and the driving chain can be used to drive the moving platform 2 to move, thereby greatly reducing the cost of moving the stage lighting.

[0048] Specifically, the first drive chain 301 and the second drive chain 302 are both roller chain structures. In order to prevent the first drive chain 301 and the second drive chain 302 from deforming and bending due to their own weight, a supporting structure for supporting the first drive chain 301 and the second drive chain 302 is also provided in the drive platform 3, so that one side of the first drive chain 301 and the second drive chain 302 faces the moving platform 2 for plug-in cooperation with the plug-in structure on the moving platform 2.

[0049] In the above embodiments, please refer to Figure 1-5The length of the offset platform 4 is greater than that of the moving platform 2, so as to prevent the moving platform 2 from being blocked by the edge of the slide rail 1 and being unable to slide into the offset platform 4. A groove 201 is provided along the length direction on the side of the moving platform 2 away from the driving platform 3, and a protrusion 601 that can slide in the groove 201 is fixedly connected to the slide plate 6. When the slide plate 6 is not sliding, the moving platform 2 can slide through the slide plate 6 in the slide rail 1 without being blocked. A telescopic rod 5 is fixedly installed on the bottom surface of the slide rail 1, and the telescopic end of the telescopic rod 5 is fixedly connected to the slide plate 6.

[0050] Furthermore, the offset platform 4 is provided with a slide track 401 for the sliding portion of the slide plate 6 connected to the telescopic rod 5. Specifically, in order to connect the telescopic rod located on the bottom surface of the slide rail 1 to the slide plate 6, the slide track 401 opened on the surface of the offset platform 4 is for the connecting portion of the slide plate 6 and the telescopic rod 5 to pass through. When the telescopic rod 5 is extended or retracted, the convex head 601 on the slide plate 6 can be used to drive the moving platform 2 to slide along the extension direction of the telescopic rod 5. The convex head 601 located in the groove 201 and the moving platform 2 are relatively stationary in the extension direction of the telescopic rod 5. Therefore, when the convex head 601 is located in the groove 201 of the moving platform 2, the extension or retraction of the telescopic rod 5 can be used to drive the moving platform 2 to move along the extension direction of the telescopic rod 5.

[0051] Specifically, the moving platform 2 and the stage lights on the offset platform 4 will not interfere with other moving platforms 2 and stage lights, so as to prevent the moving platform 2 or the stage lights on the moving platform 2 from colliding with other moving platforms 2 or the stage lights on the moving platform 2 after moving to the offset platform 4.

[0052] In order to reduce the friction resistance when the moving platform 2 moves along the slide rail 1, the bottom surface of the moving platform 2 is rotatably connected to a roller 202, and the rolling direction of the roller 202 is the same as the moving direction of the moving platform 2. When the slide plate 6 pushes the moving platform 2 to move onto the offset platform 4 or resets it from the offset platform 4 to the slide rail 1, sliding friction occurs between the roller 202 and the surface of the slide rail 1 or the offset platform 4.

[0053] In the above embodiments, please refer to Figure 6-11 A conductive track 12 is provided on one side of the slide rail 1 close to the driving platform 3 along the length direction, and a conductive head 13 for cooperating with the conductive track 12 is fixed on the side of the moving platform 2. The moving platform 2 uses the conductive head 13 to cooperate with the conductive track 12 to power the electrical equipment on the moving platform 2.

[0054] Second embodiment:

[0055] A stage lighting that can be easily switched and extended, please refer to Figure 1-11On the basis of the first embodiment, the difference from the first embodiment lies in that a fixing plate 7 is fixedly connected to the side of the moving platform 2 facing the driving platform 3, at least one control box 8 is installed on the fixing plate 7, a plug plate 9 is slidably connected in the control box 8, and a friction plate 901 for contacting the driving platform 3 is provided between the first plug block 902 and the second plug block 903, both sides of the plug plate 9 contact the inner wall of the control box 8, and the sliding direction of the plug plate 9 is orthogonal to the surface of the driving platform 3 facing the moving platform 2.

[0056] Furthermore, a fixed iron sheet 15 is fixedly connected to the back of the plug board 9, and an electromagnet 14 for attracting the fixed iron sheet 15 is installed in the control box 8. The control box is provided with a spring 16 in a compressed state between the plug board 9 and the inner wall of the control box 8. After the electromagnet 14 is energized, it can attract the fixed iron sheet 15, causing the plug board 9 to slide toward the direction of the electromagnet 14, further compressing the spring 16, but will not make the fixed iron sheet 15 fit the electromagnet 14, and the spring 16 also retains a compression margin. One side of the plug board 9 is fixedly connected to the rotating shaft of the bidirectional motor 10, and the bidirectional motor 10 is slidably installed on the outer wall of the control box 8. The bidirectional motor 10 can rotate forward or reverse, thereby achieving the purpose of inserting different plugs on the plug board 9 into the corresponding drive chains.

[0057] Specifically, when the first plug block 902 is inserted to cooperate with the first drive chain 301, the second plug block 903 and the friction plate 901 are both away from the drive platform 3. When the second plug block 903 is inserted to cooperate with the second drive chain 302, the first plug block 902 and the friction plate 901 are both away from the drive platform 3. The friction force generated by the contact between the friction plate 901 and the drive platform 3 prevents the moving platform 2 from sliding.

[0058] When specifically switching the order of the stage lights on the slide rail 1, for example, the original arrangement order of the stage lights on the slide rail 1 is stage light a, stage light b, stage light a, stage light b, and when you want to switch the arrangement order of the stage lights on the slide rail 1 to stage light a, stage light a, stage light b, stage light b, you need to move the stage light a or the stage light b in the middle of the slide rail 1 to the offset table 4, and then the two identical stage lights are close to each other and away from different stage lights. At this time, the remaining two stage lights a, one stage light b, or one stage light a and two stage lights b on the slide rail 1 are respectively located on both sides of the offset table 4, and then the stage lights on the offset table are reset back to the slide rail 1, so that the switching of the stage lights can be conveniently completed.

[0059] The third embodiment:

[0060] A stage lighting that can be easily switched and extended, please refer to Figure 1-11On the basis of the second embodiment, the difference from the second embodiment is that two control boxes 8 parallel to each other are installed on the fixed plate 7, and the plug board 9 in the control box 8 is fixedly connected by a transmission rod 11. The control box 8 is provided with a transmission rod slide groove 802 for the transmission rod 11 to slide along the sliding direction of the plug board 9. Similarly, the transmission rod slide groove 802 can also allow the output shaft of the two-way motor 10 to slide. The sliding direction of the transmission rod 11 relative to the control box 8 is parallel to the axis of the spring in the control box 8. One end of the transmission rod 11 is connected to the output end of the two-way motor 10. The two-way motor 10 is slidably installed on the side wall of one of the control boxes 8. The control box 8 is fixedly connected to two motor guide blocks 801 on the side wall, so that the two-way motor 10 can slide in a direction parallel to the axis of the spring 16, and at the same time, the torque generated by the two-way motor 10 can drive the plug board 9 to rotate. The two groups of control boxes 8 can further ensure that the moving platform 2 can move smoothly.

[0061] Specifically, under the drive of the bidirectional motor 10, the two corresponding plug plates 9 on the same moving platform 2 will rotate simultaneously, so that the plug block of one section is inserted into the corresponding driving chain, so as to achieve the effect of the driving chain stably driving the moving platform 2 to move.

[0062] Furthermore, one end of the slide rail 1 on which the driving platform 3 is provided is lower than the end on which the offset platform 4 is provided. When the moving platform 2 in the offset platform 4 is reset to slide toward the slide rail 1, the movement of the bottom end of the moving platform 2 can be effectively avoided from being offset due to the effect of its own gravity, thereby facilitating the reset of the moving platform 2 from the offset platform 4 to the slide rail 1.

[0063] When the present invention is in operation, the electromagnet 14 in the moving platform 2 to be moved is energized, so that the plug plate 9 moves toward the electromagnet 14, and after the friction plate 901 is out of contact with the driving platform 3, the bidirectional motor 10 rotates to insert one of the plug-in structures into the corresponding driving chain, so that the movement of the moving platform 2 can be realized conveniently. When the moving platform 2 needs to stop moving, the bidirectional motor 10 is reset to make the plug-in structure out of the driving chain, and then the electromagnet 14 is powered off, and the plug-in plate 9 is reset by the elastic force of the spring 16, and the friction force generated by the contact between the friction plate 901 and the surface of the driving platform 3 is used to stop the moving platform 2, so as to prevent the moving platform 2 from continuing to slide due to inertia.

[0064] When it is necessary to adjust the arrangement sequence of the stage lights on the slide rail 1, the moving platform 2 corresponding to the stage light to be adjusted is first moved to the offset platform 4, and the telescopic rod 5 is extended to push the moving platform 2 onto the offset platform 4. The other moving platforms 2 on the slide rail 1 adjust their positions at this time. After the other moving platforms 2 move and adjust their positions, the telescopic rod 5 is retracted to reset the slide plate 6, so that the pushed moving platform 2 returns to the slide rail 1, so that the position switching of the stage lights on the slide rail 1 can be completed conveniently without disassembling the stage lights on the moving platform 2.

[0065] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
