[0019] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] Reference Figures 1 to 6 , an embodiment of a rotation adjustment structure of a lamp of the present invention is proposed, which is installed on the lamp. The lamp includes a lamp holder 101 and a light source body 102. The light source body 102 is provided with a mounting opening 103, and the lamp holder 101 is provided with a mounting cavity 104 corresponding to the mounting opening 103. The bottom of the mounting cavity 104 is provided with an opening 105.

[0021] The rotation adjustment structure includes a central axis column 106 inserted into the mounting port 103 and the opening 105 from the upper end. The upper end of the central axis column 106 is a card plate 107. The light source body 102 is provided with a groove 108 adapted to the card plate 107. The card plate 107 is against the upper end of the mounting port 103 and is embedded in the groove 108 to connect the central axis column 106 with the light source body 102. Rotating the light source body 102 drives the central axis column 106 to rotate. The rotation adjustment structure also includes a sleeve provided outside the central axis column 106 and located at the mounting port The rotating seat 109 and the adjusting seat 110 in the mounting cavity 104, and the elastic spring clamp 111 provided in the adjusting seat 110, the central axis 106, the rotating seat 109, and the adjusting seat 110 are all hollow structures for the wire to pass through. The rotating seat 109 is fixedly engaged with the central axis 106 to form a linkage connection. The adjusting seat 110 is fixedly engaged with the mounting cavity 104. The rotating seat 109 rotates with the rotation of the central axis 106. The spring clamp 111 plays a role in the rotation and positioning of the rotating seat 109.

[0022] The upper end of the central column 106 is equipped with several latches 112. The inner wall of the rotating base 109 is equipped with a retaining block 113 that engages with the latches 112. The lower end of the central column 106 is equipped with an annular groove 114 that mates with the opening 105 of the lamp holder 101. Below the annular groove 114 are several curved retaining blocks 115. The outer surface of the curved retaining blocks 115 is inverted conical to facilitate insertion through the opening 105 of the lamp holder 101. The central column 106, rotating base 109, and opening 105 of the lamp holder 101 described above form a coaxial double-clip structure, which is tightly and securely connected and will not come loose. The entire assembly process is completed by hand, without the need for screws or additional tools, resulting in highly efficient assembly. Moreover, the lower end of the central axis column 106 in this structure has an arc-shaped block 115, which is directly engaged and fixed with the opening 105 of the lamp holder 101 to form a straight-plug structure with a simpler structure and fewer components. This is conducive to the design of ultra-thin lamps and a wider design range.

[0023] A guide post 116 extends downward from the rotating seat 109. An arcuate groove 117 is provided on the adjustment seat 110, along which the guide post 116 moves in an arc. Several adjustment latches 118 are annularly distributed on the lower end surface of the rotating seat 109. The adjustment seat 110 is provided with a spring groove, within which is embedded a spring clip 111 that is elastic and interacts with the adjustment latch 118. When the rotating seat 109 is rotated, the spring clip 111 interacts with the adjustment latch 118 by elastic force. When the rotating seat 109 stops rotating, the top of the spring clip 111 snaps into the corresponding adjustment latch 118, thereby achieving rotational positioning of the adjustment latch 118. During this process, the spring clip 111 plays an important role in rotational positioning. This structural form not only ensures the stability of the adjustment latch 118 in a specific position, but also allows the adjustment latch 118 to be flexibly adjusted when needed to meet different usage requirements. In this embodiment, the light source body 102 can rotate 290 degrees left and right.

[0024] The outer wall of the rotating base 109 is provided with an annular groove 119, embedded within which is a waterproof damping ring 120 that creates frictional damping with the mounting cavity 104. The waterproof damping ring 120 provides both waterproofing and frictional damping. When embedded between the rotating base 109 and the mounting cavity 104, the waterproof damping ring 120, due to its elasticity, creates close contact with adjacent component surfaces. When relative motion occurs between the rotating base 109 and the mounting cavity 104, the friction between the waterproof damping ring 120 and the component surface impedes this motion, thereby creating a damping effect. The magnitude of this friction depends on factors such as the material properties of the waterproof damping ring 120, the degree of compression, and the roughness of the component surface. By providing damping, the waterproof damping ring 120 reduces unnecessary vibration and shaking between components. This makes the entire structure more stable and reduces the risk of fatigue and damage caused by vibration. Whether static or dynamic, it ensures that components remain correctly positioned, improving product reliability and service life. Furthermore, friction and collision between components often generate noise. The damping effect of the waterproof damping ring 120 can absorb and reduce this vibration energy, thereby reducing the noise level. This is especially important in noise-sensitive environments, such as homes, offices or medical equipment. It can provide a quieter operating environment and enhance the user experience. Moreover, compared with traditional damping devices, the use of the waterproof damping ring 120 as a damping element can simplify the design of the product. Without the need for additional complex damping mechanisms, the damping effect can be achieved by simply selecting the appropriate material and size of the waterproof damping ring 120. This not only reduces costs, but also reduces the volume and weight of the product, and improves the flexibility of the design. In summary, the waterproof damping ring 120 can not only play a role in waterproof sealing, but also provide damping functions at the same time, with diverse functions, which significantly improves the performance and reliability of the product.

[0025] The mounting opening 103 of the light source body 102 extends downwardly from a circular edge 121. The upper end of the rotating base 109 is provided with an annular groove 122 that mates with the annular edge 121. A waterproof ring 123 is located within the annular groove 122. The annular edge 121 of the light source body 102 fits into the annular groove 122 of the rotating base 109. The waterproof ring 123 acts as a waterproof barrier to prevent the wires located in the hollow portion from getting wet.

[0026] A guide slot 124 is provided on the outer wall of the adjustment seat 110 , and a guide bar is provided on the inner wall of the installation cavity 104 . The guide slot 124 and the guide bar engage with each other to secure the adjustment seat 110 into the installation cavity 104 .

[0027] A pin 125 is provided inside the mounting opening 103 of the light source body 102 , and the rotating seat 109 has a pin groove 126 . The pin 125 is engaged in the pin groove 126 to play a guiding and engaging role.

[0028] During assembly, the central axis column 106 is inserted into the mounting opening 103 from the upper end, and the rotating seat 109 is sleeved on the outside of the central axis column 106. During this process, the pin groove 126 of the rotating seat 109 is engaged with the pin position 125 on the inner side of the mounting opening 103, thereby playing a guiding and locking role, and the bayonet 112 at the upper end of the central axis column 106 is engaged with the block 113 on the inner side wall of the rotating seat 109; then, the adjustment seat 110 is installed into the mounting cavity 104. During this process, the guide slot 124 on the outer side wall of the adjustment seat 110 is engaged with the guide bar on the inner side wall of the mounting cavity 104 to make the adjustment The seat 110 is snap-fitted into the mounting cavity 104, and then the rotating seat 109 is placed on the adjustment seat 110. The guide column 116 extending downward from the rotating seat 109 can move in an arc along the arc groove 117 of the adjustment seat 110. After the central axis column 106 passes through the adjustment seat 110, it continues to be snapped into the opening 105 of the mounting cavity 104 of the lamp holder 101. The outer side surface of the arc-shaped block 115 of the central axis column 106 is in the shape of an inverted cone, so that the arc-shaped block 115 can be smoothly inserted through the opening 105 of the lamp holder 101, and the annular groove 114 of the central axis column 106 is snapped into the opening 105. The central axis column 106, the rotating seat 109, and the opening 105 of the lamp holder 101 of the above structure form a coaxial double-clip structure, which is tightly and securely combined and will not loosen. Moreover, the entire assembly process is completed barehanded, without the need for screws or additional tools, and the assembly efficiency is high. In addition, when the angle needs to be adjusted, the light source body 102 is rotated left or right to adjust the direction of the light source body 102. The rotation of the light source body 102 drives the central axis column 106 and the rotating base 109 to rotate synchronously. The adjusting base 110 and the lamp holder 101 are fixed. When the rotating base 109 rotates, the spring clamp 111 interacts with the adjustment grid 118 by elastic force. When the rotating base 109 stops rotating, the top of the spring clamp 111 is snapped into the corresponding adjustment grid 118, thereby achieving the rotational positioning of the adjustment grid 118. The position of the light source body 102 can be flexibly adjusted to meet different usage requirements. In this embodiment, the light source body 102 can rotate 290 degrees left or right.

[0029] The snap-fit ​​structure is highly convenient to install, enabling rapid assembly of components without the need for complex tools or tedious manual labor. This significantly improves production efficiency and reduces assembly time and labor costs. Whether used on large-scale production lines or in small-scale manual assembly, the snap-fit ​​structure streamlines the installation process. Furthermore, the snap-fit ​​structure offers high stability, providing a secure connection once secured. The precisely designed snap-fit ​​notch 112 and snap-fit ​​block 113 ensure a tight fit between components, effectively preventing loosening and displacement. This stability ensures that the product will not malfunction due to component movement or separation during use, thereby enhancing product reliability and service life. Furthermore, the snap-fit ​​structure is highly removable and easy to maintain. While providing a secure fit, it can also be disassembled relatively easily for repairs or component replacement. This makes product maintenance more convenient and reduces repair costs. Compared to some permanent connection methods, the snap-fit ​​structure's removable nature offers greater flexibility for product upgrades and improvements. The modular structure allows components to be disassembled for packaging and shipping, reducing packaging volume and lowering packaging and transportation costs. The snap-fit ​​structure is cost-effective and generally does not require additional fasteners such as screws and nuts, reducing the number and cost of parts. The structure is simple and scientific, the design is ingenious, and the number of parts is small, effectively simplifying the processing steps and saving material costs. At the same time, the simplified assembly process also reduces management and logistics costs during the production process. In addition, the reliability of the snap-fit ​​structure reduces product quality issues and after-sales repair costs caused by connection problems. The snap-fit ​​structure has high design flexibility and can be flexibly designed and adjusted according to different product design requirements. It can adapt to parts of various shapes and sizes and can be used in combination with other connection methods, providing product designers with more creative space. Since no tools are required to reach into the product for screw assembly, the product size design is not restricted, and the product style design is also unrestricted, with a wide range of design options. The snap-fit ​​structure can also achieve hidden connections, making the product appearance more simple and beautiful. In addition, the waterproof damping ring 120 integrates waterproofing and damping, effectively simplifying the structure, and has a high waterproof coefficient and high safety performance.

[0030] The utility model realizes a simple and reasonable structure and ingenious design. The central axis column 106, the rotating seat 109, and the opening 105 of the lamp holder 101 form a coaxial double-buckle structure, which is tightly and firmly combined and will not loosen.
