Description

Technical Field

[0001] This application relates to the field of lighting fixtures, and more particularly to a hanging rotating decorative lamp. Background Technology

[0002] Traditional hanging rotating decorative lights consist of a lamp frame from which decorative elements are suspended. A light source is fixedly mounted on the lamp frame, and a drive motor is also fixedly mounted on the lamp frame. The output shaft of the drive motor is connected to the decorative elements, thus enabling the decorative elements to rotate and serve a decorative purpose. However, in the above-mentioned traditional hanging rotating decorative lights, the decorative elements do not have a light source installed on them. Because the decorative elements rotate relative to the lamp frame, it is also difficult to install a light source on the decorative elements. In other words, the decorative elements cannot emit light and only serve a decorative purpose, resulting in a generally poor aesthetic appeal for the decorative lights. Utility Model Content

[0037] Reference Figure 1A protective shell 110 is fixedly installed on the lamp holder 1. Specifically, a mounting ring is installed on the lamp holder 1, and a mounting ear is integrally formed on the outer surface of the protective shell 110. The mounting ear has a mounting hole for the mounting ring to pass through, thereby installing the protective shell 110 on the lamp holder 1. The protective shell 110 can be made of plastic or metal.

[0038] Reference Figure 2 The protective shell 110 is generally spherical. The protective shell 110 includes a detachably connected first shell 111 and a second shell 112. The first shell 111 and the second shell 112 are both hemispherical structures with one open end and an inner cavity. The first shell 111 and the second shell 112 can be fastened together to form the protective shell 110. The first shell 111 and the second shell 112 can be fixed by means of bolt connection or snap-fit ​​connection.

[0039] Reference Figure 2 and Figure 4 The first shell 111 has a positioning rod 150 integrally formed on its inner wall, and the second shell 112 has a positioning post 160 integrally formed on its inner wall. The positioning post 160 has a positioning groove 161 for the positioning rod 150 to be inserted into.

This feature facilitates the installation and maintenance of internal components, improves production efficiency and maintenance convenience, and enhances the sealing and structural strength of the shell.

[0040] Reference Figure 4 A mounting base 120 is fixedly installed in the inner cavity of the protective shell 110. The mounting base 120 can be made of plastic or metal. A limiting post 130 is integrally formed on the inner wall of the protective shell 110, and a limiting groove 131 is formed on the limiting post 130. A limiting ear 140 for inserting into the limiting groove 131 is integrally formed on the mounting base 120. Through slots and through holes for screws are respectively formed on the bottom wall of the limiting groove 131 and on the limiting ear 140, thereby realizing the detachable connection between the limiting ear 140 and the limiting post 130. With this structure of mounting base 120 and limiting post 130, the drive source 6 and the fixing component 4 are stably fixed. The detachable connection between the limiting ear 140 and the limiting groove 131 simplifies the installation and replacement process of internal components. The limiting ear 140 is inserted into the limiting groove 131 to achieve initial positioning and improve the ease of installation. This design improves the overall structural rigidity and vibration resistance, reduces noise and displacement during operation, and facilitates maintenance and adjustment, thereby reducing production costs.

[0041] Reference Figure 2The drive source 6 is fixedly mounted on the mounting base 120, which serves to fix and support the drive source 6. The drive source 6 is a motor, which has a stable driving force. The drive source 6 includes a rotatable output shaft 61, and the mounting base 120 has a through hole for the output shaft 61 to pass through. In addition to a motor, the drive source 6 can also be other devices that can provide rotational power, such as a pneumatic motor.

[0042] Reference Figure 2 The fixing member 4 is fixedly installed on the surface of the mounting base 120 away from the drive source 6. The mounting base 120 serves to fix and support the fixing member 4. The fixing member 4 also has a through hole for the output shaft 61 to pass through.

[0043] Reference Figure 2 The fixing component 4 is a circuit board, which has good electrical connection performance and integration. Two conductive plates 7 are provided, one large and one small, and are coaxially arranged. The annular conductive plate 7 is usually made of a highly conductive metal, such as copper. Besides the circuit board, the fixing component 4 can also adopt other structures with supporting and conductive functions, such as a plastic plate with a conductive coating.

[0044] Reference Figure 1 and Figure 2 A wiring socket 9 is fixedly installed on the fixing component 4. The wiring socket 9 contains pins soldered to the fixing component 4. The fixing component 4 and the light source 3 on the lamp holder 1 are electrically connected to the wiring socket 9 via wires (not shown in the figure). The wiring socket 9 provides a standardized connection interface, facilitating quick plugging and unplugging and replacement of the light source 3. This feature simplifies the installation and maintenance process, reduces tool dependence, improves product maintainability and user experience, and reduces the risk of failure due to wiring errors.

[0045] Reference Figure 2 The fixing component 4 and the driving source 6 are electrically connected to the wiring socket 9 via wires. The fixing component 4 supplies power to the driving source 6, ensuring a stable power supply for the driving source 6 while controlling the rotation of the rotating component 5. This design avoids power interruptions or voltage fluctuations that may occur due to power source separation, eliminates the need for an independent power supply for the driving source 6, simplifies the structure, and improves the working efficiency and reliability of the driving source 6. This ensures the synchronization of the rotation and illumination of the decorative component 2, enhancing the overall harmony of the decorative effect.

[0046] Reference Figure 1 and Figure 2The rotating component 5 is also a circuit board, located on the side of the fixed component 4 away from the drive source 6. A wiring socket 9 with the same structure as the wiring socket 9 on the fixed component 4 is also fixedly mounted on the rotating component 5. The rotating component 5 is electrically connected to the light source 3 on the decorative component 2 via a wire and the wiring socket 9 (not shown in the figure). Besides a circuit board, the rotating component 5 can also be other structures capable of mounting conductive pins 8 and achieving rotational conductivity, such as a rotating disk with conductive pins.

[0047] Reference Figure 2 The conductive feet 8 on the rotating component 5 are also made of a highly conductive metal. The conductive feet 8 are elastic and welded to the rotating component 5. The conductive feet 8 are inclined towards the fixing component 4 and fit against the conductive sheet 7 to ensure good electrical contact. When the rotating component 5 rotates, the conductive feet 8 slide on the annular conductive sheet 7, maintaining the electrical connection.

[0048] Reference Figure 5 An anti-rotation plane 612 is formed on the circumferential sidewall of the output shaft 61. An anti-rotation groove 51 is provided on the rotating component 5 for the output shaft 61 to insert and pass through, and the anti-rotation groove 51 extends through the two opposing end faces of the rotating component 5. The groove wall of the anti-rotation groove 51 fits and abuts against the anti-rotation plane 612, enabling the drive source 6 to drive the rotating component 5 to rotate. This effectively prevents relative rotation between the rotating component 5 and the output shaft 61, ensures accurate transmission of drive torque, reduces energy loss and component wear, improves rotational smoothness and control accuracy, thereby extending the service life of the drive source 6 and the rotating component 5.

[0049] Reference Figure 1 and Figure 5 The output shaft 61 has a threaded groove 611 (thread not shown in the figure) on its axial end face. The hanging rotating decorative light also includes a hanging ring 100 with external threads, which is threadedly connected to the output shaft 61. A through hole is provided on the second housing 112 for the hanging ring 100 to pass through, and the decorative piece 2 is suspended on the hanging ring 100. This threaded connection provides a stable suspension mechanism, allowing the decorative piece 2 to be reliably suspended and achieving a flexible connection between the decorative piece 2 and the output shaft 61. The decorative piece 2 can rotate and sway freely, enhancing its aesthetics. Simultaneously, the threaded design enhances installation convenience, prevents the decorative piece 2 from loosening during rotation, and improves safety.

[0050] Reference Figure 2 and Figure 5A limiting ring 170 is fitted onto the output shaft 61, located on the side of the rotating component 5 away from the fixed component 4. A nut 180 is also threaded onto the threaded section of the lifting ring 100, located on the side of the limiting ring 170 away from the rotating component 5. The two axial end faces of the limiting ring 170 respectively abut against the rotating component 5 and the nut 180. The end face of the rotating component 5 near the fixed component 4 forms a shoulder clearance fit with the anti-rotation plane 612, thereby limiting the rotation of the rotating component 5 axially. This design allows for flexible adjustment of the height and position of the decorative component 2, enhancing installation adaptability.

[0051] The assembly principle of a hanging rotating decorative lamp according to an embodiment of this application is as follows: First, the drive source 6 and the fixing component 4 are fixedly installed on the mounting base 120. Next, the rotating component 5 is sleeved on the output shaft 61, the limiting ring 170 is sleeved on the output shaft 61, and the hanging ring 100 with a nut 180 is threadedly fixed on the output shaft 61. Then, wires are connected to achieve electrical connection between the light source 3 on the lamp holder 1 and the light source 3 on the decorative component 2. Next, the mounting base 120 is fixedly installed on the first petal housing 111, and then the second petal housing 112 is fixedly connected to the first petal housing 111. Finally, the protective shell 110 is connected to the lamp holder 1, and the decorative component 2 is suspended on the hanging ring 100.

[0052] This hanging rotating decorative light solves the problem of traditional decorative lights where the light source 3 is difficult to install due to the rotation of the decorative part 2 by setting light sources 3 on both the lamp holder 1 and the decorative part 2, and achieving electrical connection with the annular conductive plate 7 on the fixing part 4 and the conductive foot 8 on the rotating part 5. When the driving source 6 drives the rotating part 5 and the decorative part 2 to rotate, the light source 3 on the decorative part 2 can continuously emit light, which works in conjunction with the light source 3 on the lamp holder 1 to create a unique dynamic decorative effect, greatly improving the aesthetics of the decorative light. At the same time, the reasonable design and coordination of various components, such as the detachable structure of the protective shell 110, the setting of the mounting base 120 and the limiting post 130, improve the production efficiency, maintenance convenience and overall stability of the product, and enhance the practicality and reliability of the product, representing a significant improvement and enhancement compared to traditional hanging rotating decorative lights.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
