Abstract
Description
Technical Field
[0001] This utility model relates to the field of stage lighting technology, and more specifically, to a stage light with an integrated shaft sleeve and housing. Background Technology
[0002] In the field of stage lighting equipment, the base chassis is generally used to install electronic components such as power supplies and control panels, while the support arm can drive the lamp head to rotate in multiple dimensions around the base chassis. The support arm and the base chassis achieve horizontal rotation of the lamp head through the cooperation of a rotating shaft and a bushing. In existing solutions, relying on the supporting force of the base plate in the base chassis, the bushing can be selectively fixed to the base plate of the base chassis. However, a sheet metal platform needs to be built to install the bushing to ensure connection stability. But in this structure, the rotating shaft and bushing usually need to pass through the entire base chassis, dividing the internal space of the base chassis into multiple areas along the height of the base chassis. This significantly increases the difficulty of arranging power modules, control circuits, and other components, as well as the difficulty of cross-area wiring, thus increasing wiring complexity and potential safety hazards.
[0003] Furthermore, existing connections between the bushing and the base housing often employ detachable structures, such as bolt fixation. These connections are prone to loosening under long-term rotational loads, leading to decreased rotational accuracy of the support arm and even wobbling and abnormal noise, affecting equipment reliability. Moreover, to meet the waterproofing requirements for outdoor use or humid environments, multiple sealing rings are required at the bushing-base housing interface. This not only increases the number of parts and assembly steps but also risks degrading waterproofing performance due to aging of the sealing rings, potentially causing moisture damage to internal components. Therefore, optimizing the internal space layout of the base housing while ensuring rotational connection strength and waterproofing performance has become a pressing technical challenge in current stage lighting structural design. Utility Model Content
[0004] The present invention aims to overcome at least one defect (deficiency) of the prior art and provide a stage lamp with an integrated bushing and housing to improve the connection strength between the bushing and the housing.
[0005] The technical solution adopted by this utility model is to provide a stage light with an integrated bushing and housing, including a housing with a cavity, a support arm pivotally connected to the top of the housing, and a lamp head pivotally connected to the support arm. The cavity of the housing is formed by a top plate, a bottom plate, and a side plate. The housing and the support arm are pivotally connected to each other through a rotating assembly. The rotating assembly includes a bushing integrally formed on the top plate and a rotating shaft fixedly connected to a horizontal bracket of the support arm. The bushing and the rotating shaft are rotatably connected by a bearing.
[0006] In this technical solution, the integral connection between the bushing and the top plate greatly improves the firmness of the connection between the two, making it less prone to breakage, reducing maintenance costs, and saving complex processes such as connecting the bushing to the chassis and improving the sealing of the connection between the bushing and the chassis. This reduces the use of parts, improves production efficiency, and also avoids the use of the support arm due to the loose connection between the bushing and the chassis.
[0007] Furthermore, the top plate and the bushing are connected by a boss, and the top plate, the boss, and the bushing are integrally formed.
[0008] Furthermore, the side panel of the chassis includes a left panel and a right panel arranged opposite to each other, and the ends of the left panel and the right panel are integrally connected to the opposite sides of the top panel.
[0009] In this technical solution, since the chassis is connected to the support arm and contains various components, it has a certain weight. Connecting the top plate and the left and right plates as a whole helps to improve the connection firmness, thereby enhancing the load-bearing capacity and making it less prone to loosening and damage; it also reduces the installation process and the use of installation parts.
[0010] Furthermore, handles are provided on the left and right plates respectively.
[0011] In this technical solution, the handles on both sides provide support points on both sides when the chassis is moved, making it easier to move the chassis.
[0012] Furthermore, the top plate has a plurality of first reinforcing ribs on one side near the bushing, the first reinforcing ribs extending from the bushing toward the edge of the top plate. The top plate also has at least two sets of second reinforcing ribs extending perpendicular to the direction of the first reinforcing ribs on one side near the bushing.
[0013] In this technical solution, since the top plate is integrally connected with a bushing, and the bushing needs to support the rotation of the rotating shaft connected to the support arm, the top plate needs to provide sufficient support force. The crisscrossing arrangement of the first and second reinforcing ribs can increase the support capacity of the top plate and improve the overall working stability of the chassis.
[0014] Furthermore, the bushing is located inside the cavity of the chassis, the top plate is provided with a through hole for the rotating shaft to pass through, the rotating shaft passes through the through hole and is rotatably connected to the bushing, and the side of the top plate near the support arm is provided with a plurality of third reinforcing ribs extending from the through hole to the edge of the top plate.
[0015] In this technical solution, the third reinforcing rib can further enhance the support strength of the top plate, and the two adjacent third reinforcing ribs form an air duct, which can guide the airflow across the chassis surface in an orderly manner, which is beneficial to the heat dissipation of the chassis surface.
[0016] Furthermore, the top plate and the bushing are connected by a boss, and the top plate, the boss, and the bushing are integrally formed.
[0017] In this technical solution, since the rotating shaft rotates relative to the bushing via bearings, the bushing is continuously subjected to force from the rotating shaft during the operation of the stage lights. Therefore, the bushing needs to be firmly connected to the top plate to prevent damage. The protrusion provided in this solution increases the contact area between the top plate and the bushing, significantly enhancing the connection strength between the bushing and the top plate and improving the firmness of the connection.
[0018] Furthermore, a gap is provided between the bottom end of the bushing and the base plate. Preferably, the gap between the bottom end of the bushing and the base plate is less than half the distance between the top plate and the base plate.
[0019] In this technical solution, the bottom end of the bushing is suspended, which avoids the bushing dividing the inside of the chassis cavity into different spaces. The internal parts, modules and circuits can be connected through the interval, which optimizes the spatial layout and reduces the complexity and difficulty of wiring.
[0020] Furthermore, the rotating assembly also includes a bearing pressure plate, which is connected to the top plate or bushing, and the edge of the bearing pressure plate abuts against the outer ring of the bearing.
[0021] Furthermore, it also includes a drive assembly for driving the rotating shaft to rotate relative to the bushing. The drive assembly includes a drive motor, a drive wheel, a belt, and a driven wheel, all located inside the cavity of the housing. The driven wheel is fixedly connected to the end face of the rotating shaft away from the support arm. The drive motor drives the drive wheel, and the drive wheel drives the driven wheel to rotate via the belt.
[0022] Furthermore, the bushing is located within the cavity of the chassis. This arrangement makes the structure more compact and reduces the overall space occupied by the chassis.
[0023] Furthermore, the bushing integrated housing includes a bushing and at least two bearings. The bushing is disposed outside the rotating shaft and between two adjacent bearings, and the upper and lower edges of the bushing abut against the inner ring of the bearing.
[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0025] (1) In this utility model, the integral connection between the bushing and the top plate greatly improves the firmness of the connection between the two, making it less prone to breakage, reducing maintenance costs, and saving complex processes such as connecting the bushing to the chassis and improving the sealing of the connection between the bushing and the chassis. This reduces the use of parts, improves production efficiency, and also avoids the loose connection between the bushing and the chassis, which would affect the use of the support arm.
[0026] (2) In this utility model, a gap is set between the bottom end of the bushing and the base plate to avoid the bushing dividing the interior of the chassis cavity into different spaces. The internal parts modules and lines can be arranged through the gap, which optimizes the spatial layout and reduces the complexity and difficulty of wiring. Attached Figure Description

Detailed Implementation
[0035] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.
[0036] Example 1
[0037] Combination Figures 1 to 6 This embodiment provides a stage light with an integrated bushing and housing, including a housing 400 having a cavity, a support arm 510 pivotally connected to the top of the housing, and a lamp head 700 pivotally connected to the support arm. The cavity of the housing 400 is formed by a top plate 100, a bottom plate 300, and side plates. The housing 400 and the support arm 510 are pivotally connected to each other via a rotating assembly. The rotating assembly includes a bushing 110 integrally formed on the top plate 100 and a rotating shaft 500 fixedly connected to a horizontal bracket of the support arm 510. The bushing 110 and the rotating shaft 500 are rotatably connected via a bearing 520. For example, there are multiple side plates, and the top plate 100 and the side plates are made of aluminum alloy or magnesium alloy. The rotating shaft 500 is fixedly connected to the support arm 510 to prevent loosening during rotation. The support arm 510 is a U-shaped support arm, and the lamp head 700 is pivotally connected to the inner side of the U-shaped support arm.
[0038] The bushing 110 is integrally connected to the top plate 100, which greatly improves the strength of the connection, makes it less prone to breakage, reduces maintenance costs, and saves on complex processes such as connecting the bushing 110 to the chassis and improving the sealing of the connection. This reduces the number of parts used, improves production efficiency, and also prevents the connection between the bushing 110 and the chassis from becoming loose and affecting the rotational movement between the chassis 400 and the support arm 510. Preferably, the bushing 110 can be integrally formed outside or inside the cavity of the chassis 400 according to design requirements. In this embodiment, the bushing 110 is located inside the cavity of the chassis 400 and is formed by a recess on one side of the top plate 100 near the support arm 510 towards the other side, making the structure compact and reducing the overall space occupied by the chassis 400.
[0039] Preferably, the side panels include a left panel 210 and a right panel 220 arranged opposite to each other. The ends of the left panel 210 and the right panel 220 are integrally connected to the opposite sides of the top panel 100, and each of the left panel 210 and the right panel 220 is connected to a handle 211. The handles 211 on both sides provide two support points when the chassis is moved, facilitating the movement of the chassis. Furthermore, since the chassis is connected to the support arm 510 and contains various components, it has a certain weight. Integrating the top panel 100 with the left and right panels helps to improve the connection's firmness, thereby enhancing its load-bearing capacity and preventing loosening and damage.
[0040] Preferably, the side panels include a front panel 230 and a rear panel 240, and the bottom plate 300 is integrally connected to the bottom of the front panel 230 and the rear panel 240. The integral connection between the bottom plate 300 and the front and rear side panels also improves the strength of the connection, and the side panels do not need to be separately connected to the top plate 100 and the bottom plate 300, thereby reducing installation steps; in addition, the integral connection also improves the sealing performance of the chassis.
[0041] In this embodiment, the top plate 100, left plate 210 and right plate 220 are integrally connected to form the top frame 130 of the chassis, and the bottom plate 300, front plate 230 and rear plate 240 are integrally connected to form the bottom frame of the chassis. The top frame 130 and the bottom frame of the chassis are connected to form a chassis 400 with a cavity.
[0042] Preferably, a display 231 is provided on the front panel 230. The display 231 facilitates the setting of the lamp mode and the real-time monitoring of the working status. Typically, the display 231 is connected to the circuit module inside the cavity.
[0043] Preferably, there is a gap between the bottom end of the bushing and the base plate.
[0044] A gap 410 is provided between the bottom end of the bushing 110 and the base plate 300 to avoid the bushing 110 dividing the interior of the chassis cavity into different spaces. The internal parts, modules and circuits can be connected through the gap 410, which optimizes the spatial layout and reduces the complexity and difficulty of wiring.
[0045] Preferably, the height of the gap 410 between the bottom end of the bushing 110 and the base plate 300 is less than half the height of the front plate 230. The height of the front plate 230 can be understood as the distance between the top plate 100 and the base plate 300. Setting the gap 410 to be less than half the height of the side plate optimizes the internal space layout of the cavity while ensuring that the bushing 110 has sufficient length to connect with the rotating shaft 500, improving the stability of the connection between the two, so as to support the smooth rotation of the support arm 510.
[0046] For example, the height of the interval 410 can be 1 / 5, 1 / 4, or 1 / 3 of the height of the front panel 230, etc.
[0047] Preferably, the system further includes a bearing pressure plate 521, which is connected to the top plate 100 or the bushing 110, and the edge of the bearing pressure plate 521 abuts against the outer ring of the bearing 520. The pressure plate prevents the bearing 520 from loosening during operation and improves its stability.
[0048] For example, the bearing pressure plate 521 is a circular ring, which allows the bearing 520 to be pressed in the circumferential direction, further improving its operational stability. The bearing pressure plate 521 can be disposed on the top of the bushing 110, the bottom of the bushing 110, or both. In this embodiment, the bearing pressure plate 521 is connected and fixed to the top of the bushing 110 by a pressure plate screw 522. Both the bearing pressure plate 521 and the top of the bushing 110 are provided with fixing holes that match the pressure plate screw 522. The fixing holes are arranged along the circumferential direction, which greatly improves the connection strength between the bearing pressure plate 521 and the bushing 110.
[0049] Preferably, the integrated bushing housing includes a bushing 530 and at least two bearings 520. The bushing 530 is disposed outside the rotating shaft 500 and between two adjacent bearings 520, with both the upper and lower edges of the bushing 530 abutting against the inner ring of the bearing 520. The two adjacent bearings 520 support each other through the bushing 530, thereby simultaneously improving the stability of the two bearings 520 during operation. For example, the number of bearings 520 can be two, three, or four, etc., with two bearings 520 provided on the rotating shaft 500, respectively fitted onto the upper and lower ends of the rotating shaft 500.
[0050] Preferably, the top plate 100 has a plurality of first reinforcing ribs 120 on one side near the bushing 110, and the first reinforcing ribs 120 extend from the bushing 110 toward the edge of the top plate 100. The top plate 100 also has at least two sets of second reinforcing ribs 121 extending in a direction perpendicular to the first reinforcing ribs 120 on one side near the bushing 110. The bushing 110 is located in the cavity of the housing 400, the top plate 100 has a through hole 140 for the rotating shaft 500 to pass through, the rotating shaft 500 passes through the through hole 140 and is rotatably connected to the bushing 110, and the top plate 100 has a plurality of third reinforcing ribs 122 extending from the through hole 140 toward the edge of the top plate 100 on one side near the support arm 510.
[0051] Preferably, the drive assembly 600 includes a drive motor 610, a drive wheel 620, a belt 630, and a driven wheel 640, all located within the cavity of the housing 400. The driven wheel 640 is fixedly connected to the rotating shaft 500. The drive motor 610 drives the drive wheel 620, and the drive wheel 620 drives the driven wheel 640 to rotate via the belt 630, thereby driving the rotating shaft 500 to rotate relative to the bushing 110.
[0052] For example, the drive motor 610 is connected to the base plate 300, and the drive motor 610 is connected to the mounting plate 611. The driven wheel 640 is connected and fixed to the rotating shaft 500 by a plurality of driven wheel screws 641, so that the two are firmly connected and the drive motor 610 can smoothly drive the rotating shaft 500.
[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the technical solution of this utility model, and are not intended to limit the specific implementation of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of this utility model should be included within the protection scope of the claims of this utility model.
