Description

Technical Field

[0001] This utility model relates to the technical field of stage light lifting and limiting devices, and in particular to a stage light lifting and limiting device. Background Technology

[0002] The stage light lifting limit device is a device that limits the stage light after it has been raised or lowered to a suitable position. The stage light is fixed to the lifting frame and raised or lowered by the lifting rod. Once it has been raised or lowered to the suitable position, it is fixed in place.

[0003] The inventors discovered during routine use of the stage light lifting limit device that when the stage light is fixed to the surface of the lifting rod, if the lifting rod is too long, it will cause the lifting rod to bend and deform, thereby changing the position of the light beam and resulting in the inability to achieve the expected effect, such as glare, thus causing problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a stage light lifting and limiting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a stage light lifting and limiting device, comprising a fixed rod, a support frame provided on the surface of the fixed rod, an adjusting ring rotatably connected to the surface of the fixed rod, a lifting rod provided inside the fixed rod, a threaded groove provided on the surface of the lifting rod, a rectangular plate provided at one end of the lifting rod, a U-shaped frame provided on the surface of the rectangular plate, a stage light provided on the surface of the U-shaped frame, a support device provided on the surface of the lifting rod, the support device comprising a bracket fixedly connected to the surface of the lifting rod, a support rod rotatably connected to the surface of the bracket, the other end of the support rod fitting against the surface of the rectangular plate, a slot provided at the bottom of the rectangular plate, a slider slidably connected to the surface of the support rod, and the slider being inserted into the slot.

[0006] The aforementioned components achieve the following effects: under the action of the support rod, the rectangular plate will not bend, thus avoiding deformation. When it is necessary to limit the lifting of the stage light, the adjusting ring is turned by hand to adjust the height of the lifting rod. After adjusting to the appropriate height, the lifting rod is limited by the adjusting ring. The stage light is then installed on the surface of the rectangular plate, the support frame is opened, and the fixing rod is erected on the stage surface, thereby achieving the function of limiting the lifting of the stage light.

[0007] Preferably, a spring is fixedly connected to the bottom of the slider, and the other end of the spring is fixedly connected to the bottom of the support rod.

[0008] The effect achieved by the above components is that, under the action of the spring, the slider can move upward and insert into the inside of the slot, thereby achieving the function of fixing the support rod.

[0009] Preferably, a locking rod is inserted into the side of the support rod, and one end of the locking rod is inserted into the interior of the slider.

[0010] The effect achieved by the above components is that, under the action of the lever, the position of the slider can be fixed, thus preventing the slider from moving downwards.

[0011] Preferably, a washer, which is a rubber ring, is fixedly connected to the top of the support rod.

[0012] The aforementioned components achieve the following effects: The washers prevent the support rod from directly contacting the bottom of the rectangular plate, avoiding rigid contact and deformation. When support is needed for the rectangular plate, the support rod rotates on the side of the bracket, bringing it into contact with the bottom of the rectangular plate. Again, the washers prevent direct contact and deformation. The spring allows the slider to move upwards and insert into the slot, thus fixing the support rod. After the slider is inserted into the slot, the locking rod is inserted into the slider, preventing downward movement and achieving the desired support.

[0013] Preferably, the surface of the rectangular plate is provided with a replacement device, the replacement device including a fixing plate fixedly connected to the side of the rectangular plate, a threaded rod rotatably connected to the surface of the fixing plate, and a pressing plate threadedly connected to the surface of the threaded rod, the pressing plate pressing against the surface of the U-shaped frame.

[0014] The effect achieved by the above components is that, under the action of the threaded rod, the extrusion plate can fix the U-shaped frame to the surface of the rectangular plate.

[0015] Preferably, a sliding rod is fixedly connected to the surface of the fixed plate, and a pressing plate is slidably connected to the surface of the sliding rod.

[0016] The effect achieved by the above components is that, under the action of the slide bar, the extrusion plate will not rotate with the rotation of the threaded rod.

[0017] Preferably, the surface of the U-shaped frame is provided with a through groove, the surface of the rectangular plate is provided with a circular groove, and a limiting rod is fixedly connected to the bottom of the extrusion plate. The limiting rod penetrates the through groove and is inserted into the interior of the circular groove.

[0018] The effect achieved by the above components is that, under the action of the limiting rod, the U-shaped frame will not slide on the surface of the extrusion plate, thereby achieving the limiting function.

[0019] Preferably, the side of the extrusion plate is threaded with a screw, which abuts against the surface of the threaded rod.

[0020] The aforementioned components achieve the following effects: Under the action of the screws, the position of the extrusion plate is adjusted to a suitable height and then fixed, thus achieving the function of fixing the extrusion plate. When the stage light needs to be replaced, the threaded rod is turned by hand to move the extrusion plate, thereby separating the limiting rod from the circular groove. The U-shaped frame can then be removed, and the new stage light's U-shaped frame is placed on the surface of the rectangular plate, aligning the through groove with the circular groove. The threaded rod is turned by hand, causing the extrusion plate to move smoothly downwards under the action of the sliding rod, thus allowing the limiting rod to insert into the circular groove to fix the U-shaped frame. After the extrusion plate and the U-shaped frame are in contact, the screw is screwed into the extrusion plate, with one end of the screw abutting against the surface of the threaded rod, thereby fixing the extrusion plate and achieving the function of replacing the stage light.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting up a support device, when a rectangular plate needs to be supported, the support rod is rotated on the side of the bracket, so that the support rod is in contact with the bottom of the rectangular plate. Under the action of the washer, the support rod will not directly contact the bottom of the rectangular plate, avoiding rigid contact and deformation of the support rod. Under the action of the spring, the slider can move upward and insert into the inside of the slot, thereby fixing the support rod. After the slider is inserted into the slot, the locking rod is inserted into the slider to prevent the slider from moving downward, thus achieving the supporting function. This solves the problem of the lifting rod sagging and deforming due to its long length and the number of stage lights. Attached Figure Description

[0028] Working principle: When it is necessary to limit the lifting of the stage light 6, the adjusting ring 5 is rotated by hand to adjust the height of the lifting rod 4. When the appropriate height is reached, the lifting rod 4 is limited by the adjusting ring 5, the stage light 6 is installed on the surface of the rectangular plate 7, the support frame is opened, and the fixed rod 1 is erected on the stage surface, thereby achieving the function of limiting the lifting of the stage light 6.

[0029] Reference Figure 2 The support device 2 includes a bracket 21 fixedly connected to the surface of the lifting rod 4. A support rod 22 is rotatably connected to the surface of the bracket 21. The other end of the support rod 22 is attached to the surface of the rectangular plate 7. A slot is provided at the bottom of the rectangular plate 7. A slider 23 is slidably connected to the surface of the support rod 22. The slider 23 is inserted into the slot. A spring 24 is fixedly connected to the bottom of the slider 23. The other end of the spring 24 is fixedly connected to the bottom of the support rod 22. A locking rod 26 is inserted into the side of the support rod 22. One end of the locking rod 26 is inserted into the slider 23. A washer 25, which is a rubber ring, is fixedly connected to the top of the support rod 22.

[0030] Working principle: When the rectangular plate 7 needs to be supported, the support rod 22 is rotated on the side of the bracket 21, so that the support rod 22 is in contact with the bottom of the rectangular plate 7. Under the action of the washer 25, the support rod 22 will not directly contact the bottom of the rectangular plate 7, avoiding rigid contact and deformation of the support rod 22. Under the action of the spring 24, the slider 23 can move upward and insert into the slot, thereby fixing the support rod 22. After the slider 23 is inserted into the slot, the locking rod 26 is inserted into the slider 23 to prevent the slider 23 from moving downward, thus achieving the supporting function.

[0031] Reference Figure 3 A replacement device 3 is provided on the surface of the rectangular plate 7. The replacement device 3 includes a fixed plate 31 fixedly connected to the side of the rectangular plate 7. A threaded rod 32 is rotatably connected to the surface of the fixed plate 31. A pressing plate 34 is threadedly connected to the surface of the threaded rod 32. The pressing plate 34 presses against the surface of the U-shaped frame. A sliding rod 33 is fixedly connected to the surface of the fixed plate 31. The pressing plate 34 is slidably connected to the surface of the sliding rod 33. A through groove is opened on the surface of the U-shaped frame. A circular groove is opened on the surface of the rectangular plate 7. A limiting rod 36 is fixedly connected to the bottom of the pressing plate 34. The limiting rod 36 penetrates the through groove and is inserted into the interior of the circular groove. A screw 35 is threadedly connected to the side of the pressing plate 34. The screw 35 abuts against the surface of the threaded rod 32.

[0032] Working principle: When the stage light 6 needs to be replaced, the threaded rod 32 is turned by hand to move the pressing plate 34, thereby separating the limiting rod 36 from the circular groove. The U-shaped frame is then removed, and the U-shaped frame of the new stage light 6 is placed on the surface of the rectangular plate 7, aligning the through groove with the circular groove. The threaded rod 32 is turned by hand to make the pressing plate 34 move smoothly downward under the action of the sliding rod 33, thereby inserting the limiting rod 36 into the interior of the circular groove to fix the U-shaped frame. After the pressing plate 34 and the U-shaped frame are in contact, the screw 35 is screwed into the interior of the pressing plate 34, so that one end of the screw 35 abuts against the surface of the threaded rod 32, thereby fixing the pressing plate 34 and achieving the purpose of replacing the stage light 6.
