[0028] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0029] The existing stage light shaft structure is usually a split type. During the installation process, a separate aluminum alloy shaft needs to be assembled onto the sheet metal base bracket of the stage light and then fixed with screws. This structure has some drawbacks in practical applications: (1) The assembly process is cumbersome, which increases the assembly cost; (2) The split shaft and sheet metal base bracket make the parts processing more difficult, resulting in high processing costs and long cycles; (3) The large number of parts and the variety of materials increase the procurement and management costs.

[0030] Example 1

[0031] like Figures 1-3 As shown in the figure, this embodiment provides a stage lamp shaft assembly structure, characterized in that it includes:

[0032] A support frame 1 is provided with a shaft structure 11, which is integrally formed with the support frame 1. The shaft structure 11 has a first end and a second end that are disposed opposite to each other.

[0033] The shaft structure 11 is used to connect with the rocker arm 2. The first end of the shaft structure 11 extends into the rocker arm 2, and the rocker arm 2 is sleeved around the shaft structure 11. A pressure ring 23 is provided on the first end of the shaft structure 11, and a fixed connecting plate 12 is provided around the second end of the shaft structure 11.

[0034] It also includes a connecting bolt 4, one end of which passes through the pressure ring 23, the axial structure 11 and is threadedly connected to the fixed connecting plate 12.

[0035] Specifically, in practical applications, high-strength, wear-resistant alloy plastics with good insulation properties are selected as the materials for manufacturing the support frame 1 and the shaft structure 11. For example, polycarbonate alloy plastics reinforced with glass fiber are selected. This material possesses both the high toughness and good molding and processing properties of polycarbonate, and also has high strength and wear resistance due to the reinforcement of glass fiber, which can meet the mechanical performance requirements of the stage lamp shaft assembly structure during long-term use. The rocker arm 2 is made of aluminum alloy, which reduces the overall weight while ensuring strength and improving the flexibility of the stage lamp. The connecting bolts 4 are made of stainless steel to prevent rust and corrosion and ensure the reliability of the connection.

[0036] During assembly, the manufactured rocker arm 2 is fitted onto the first end of the shaft structure 11, ensuring a smooth fit. Next, the pressure ring 23 is installed on the first end of the shaft structure 11, ensuring a tight fit between the pressure ring 23 and the rocker arm 2. Then, the fixed connecting plate 12 is installed around the second end of the shaft structure 11, and a connecting bolt 4 is threaded through the pressure ring 23 and the shaft structure 11 to connect with the fixed connecting plate 12.

[0037] In traditional stage light shaft assembly structures, the shaft and support frame 1 are separate parts, requiring multiple assembly processes such as positioning, alignment, and fixing. In this embodiment, however, the shaft structure 11 and support frame 1 are integrally formed, reducing the number of parts and assembly steps. In actual production, assembly workers do not need to spend a significant amount of time aligning and connecting the shaft and support frame 1, greatly shortening assembly time. The integral molding process reduces processing steps, such as the separate processing and surface treatment of the shaft and support frame 1 in traditional processes. This not only reduces processing costs but also decreases the scrap rate during processing. Furthermore, the reduction in the number of parts lowers raw material procurement costs and inventory management costs.

[0038] More specifically, the shaft structure 11 is disposed on the top of the support frame 1, and the shaft structure 11 and the support frame 1 are integrally formed by injection molding;

[0039] A mounting groove is provided at the junction of the support frame 1 and the second end of the shaft structure 11, and the fixed connecting plate 12 is disposed in the mounting groove. Furthermore, a protrusion is provided on the side wall of the mounting groove, the protrusion protruding from the edge of the mounting groove towards the center.

[0040] Since the shaft structure 11 and the support frame 1 are integrally formed, the process of machining and surface treating these two parts separately is reduced, thus lowering processing costs. The protrusions on the side wall of the mounting slot can automatically engage when the fixed connecting plate 12 is installed, achieving rapid positioning. Compared with traditional assembly methods, workers do not need to spend time aligning the position of the fixed connecting plate 12, further improving assembly efficiency.

[0041] Furthermore, the fixed connecting plate 12 is provided with a plurality of connecting holes, which are arranged in a ring on the fixed connecting plate 12. A plurality of connecting bolts 4 are provided, and one end of the plurality of connecting bolts 4 is threadedly connected to the connecting holes.

[0042] The axis of the connecting bolt 4 is parallel to the axis of the shaft structure 11.

[0043] Multiple annularly arranged connecting holes and multiple connecting bolts 4 on the fixed connecting plate 12 work together to make the connection between the fixed connecting plate 12 and the shaft structure 11 more stable. Compared with a single connecting bolt 4, multiple connecting bolts 4 can evenly distribute the force, avoiding structural damage or loosening caused by excessive local stress. Under the conditions of frequent rotation and vibration of the stage lights, this multi-point connection method can effectively reduce stress concentration at the connection points and extend the service life of the assembly structure.

[0044] Furthermore, it also includes a base plate 3, the bottom of which is disposed on the side of the support frame 1 opposite to the axial structure 11.

[0045] The addition of base plate 3 provides a more stable support foundation for the entire stage light's central assembly structure. During stage light operation, especially under conditions of frequent angle adjustments or external vibrations, base plate 3 can distribute the pressure from the central structure 11 and other components, preventing deformation or displacement of the support frame 1 and making the entire assembly structure more stable and reliable. Base plate 3 also facilitates connection to the stage light's mounting base.

[0046] Example 2

[0047] This embodiment provides a stage lamp, including the stage lamp axis assembly structure described above.

[0048] like Figures 1-3 As shown, specifically, the support frame 1 is provided with a first mounting position, in which a first drive motor 5 is provided. The axis of the first drive motor 5 is parallel to the axis of the shaft structure 11, and a first synchronous gear 51 is provided at the output end of the first drive motor 5.

[0049] A transmission gear 22 is provided on the rocker arm 2, and the transmission gear 22 is located on the periphery of the shaft structure 11; a synchronous belt 52 is provided between the transmission gear 22 and the first synchronous gear 51.

[0050] The structure of the first drive motor 5, the first synchronous gear 51, the synchronous belt 52, and the transmission gear 22 works together to enable the first drive motor 5 to drive the rocker arm 2 to rotate. The rocker arm 2 is used to mount the lamp head of the stage light, thus enabling the lamp head to rotate. This multi-angle rotation design greatly enriches the range of light projection angles of the stage light, meeting the needs of various complex stage lighting effects. For example, in a large-scale musical performance, the stage light can be flexibly adjusted to achieve rapid sweeping, focusing, and changing of light on the stage, bringing a more stunning visual experience to the audience.

[0051] Furthermore, a second drive motor 21 is provided on the rocker arm 2. The axis of the second drive motor 21 is perpendicular to the axis of the shaft structure 11, and a second synchronous gear 211 is provided at the output end of the second drive motor 21. The second synchronous gear 211 can be used to connect with an external structure. For example, in one embodiment, the second synchronous gear 211 is connected to an external structure so that the second drive motor 21 drives the second synchronous gear 211, causing the rocker arm 2 to rotate in the vertical direction, further enriching the illumination angle of the stage lights.

[0052] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0053] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0054] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
