[0022] 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.
[0023] Reference Figures 1 to 9 , an embodiment of the rotation adjustment structure of the 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, and the bottom of the mounting cavity is provided with an opening 105.
[0024] The rotation adjustment structure includes a central axis 106 inserted into the mounting port 103 and the opening 105 from the upper end. The upper end of the central axis 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 so that the central axis 106 is linked to the light source body 102. Rotating the light source body 102 drives the central axis 106 to rotate. The rotation adjustment structure also includes a rotating seat 109 and an adjustment seat provided outside the central axis 106 and located in the mounting cavity 104. The seat 110, the buckle cap 111 which is fixed at the end of the central axis 106 and located at the top of the lamp holder 101, and the elastic spring clip 112 which is arranged in the adjustment seat 110, the central axis 106, the rotating seat 109, and the adjusting seat 110 are all hollow structures for the passage of wires. The rotating seat 109 is fixed with the central axis 106 to form a linkage connection. The adjusting seat 110 is fixed with the mounting cavity 104. The rotating seat 109 rotates with the rotation of the central axis 106, and the spring clip 112 plays a role in rotational positioning of the rotating seat 109.
[0025] The upper end of the central axis 106 is provided with a plurality of first snap-in notches 113. The inner sidewall of the rotating base 109 is provided with a first latch 114 that engages with the first snap-in notches 113. The lower end of the central axis 106 is provided with a plurality of second snap-in notches 115. The buckle cap 111 is provided with a second latch 116 that engages with the second snap-in notches. The central axis 106, rotating base 109, and buckle cap 111 together form a coaxial double-snap mechanism, which is tightly and securely connected and prevents loosening. The entire assembly process is performed by hand, without the need for screws or additional tools, resulting in highly efficient assembly.
[0026] A guide post 117 extends downward from the rotating base 109. The adjustment base 110 is provided with an arcuate groove 118, along which the guide post 117 moves in an arc. Several adjustment latches 119 are annularly distributed on the lower end surface of the rotating base 109. The adjustment base 110 is provided with a spring groove 120, embedded within which is a spring clip 112 that is elastic and interacts with the adjustment latches 119. When the rotating base 109 is rotated, the spring clip 112 interacts with the adjustment latch 119 through elastic force. When the rotating base 109 stops rotating, the top of the spring clip 112 snaps into the corresponding adjustment latch 119, thereby achieving rotational positioning of the adjustment latch 119. During this process, the spring clip 112 plays an important role in rotational positioning. This structural form not only ensures the stability of the adjustment latch 119 in a specific position, but also allows the adjustment latch 119 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.
[0027] The outer wall of the rotating base 109 is provided with an annular groove 121, embedded within which is a waterproof damping ring 122 that creates frictional damping with the mounting cavity 104. The waterproof damping ring 122 provides both waterproofing and frictional damping. When embedded between the rotating base 109 and the mounting cavity 104, the waterproof damping ring 122, due to its elasticity, forms 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 122 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 122, the degree of compression, and the roughness of the component surface. By providing damping, the waterproof damping ring 122 reduces unnecessary vibration and shaking between components. This makes the overall 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 122 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 122 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 122. 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 122 can not only play a role in waterproof sealing, but also provide damping function at the same time, with diverse functions, which significantly improves the performance and reliability of the product.
[0028] An annular edge 123 extends downward from the mounting opening 103 of the light source body 102. An annular groove 124 is provided at the upper end of the rotating base 109 to mate with the annular edge 123. A waterproof ring 125 is provided within the annular groove 124. The annular edge 123 of the light source body 102 fits into the annular groove 124 of the rotating base 109. The waterproof ring 125 provides a waterproof function, preventing the wires located in the hollow portion from getting wet.
[0029] A guide slot 126 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 126 and the guide bar engage with each other to secure the adjustment seat 110 into the installation cavity 104 .
[0030] A pin 127 is provided inside the mounting opening 103 of the light source body 102 , and the rotating seat 109 has a pin groove 128 . The pin 127 is engaged in the pin groove 128 , thereby playing a guiding and engaging role.
[0031] During assembly, the middle shaft 106 is inserted into the mounting opening 103 from the upper end, and the rotating seat 109 is sleeved on the outside of the middle shaft 106. During this process, the pin groove 128 of the rotating seat 109 is engaged with the pin position 127 on the inner side of the mounting opening 103 to play a guiding and locking role, and the first bayonet 113 on the upper end of the middle shaft 106 is engaged with the first clamping block 114 on the inner side wall of the rotating seat 109; then, the adjusting seat 110 is installed into the mounting cavity 104. During this process, the guide slot 126 on the outer side wall of the adjusting seat 110 is engaged with the inner side wall of the mounting cavity 104. The guide bars engage with each other so that the adjustment seat 110 is engaged and fixed into the installation cavity 104, and then the rotating seat 109 is placed on the adjustment seat 110. The guide column 117 extending downward from the rotating seat 109 can move in an arc shape along the arc groove 118 of the adjustment seat 110. After the central axis 106 passes through the adjustment seat 110 and the opening 105 of the installation cavity 104 of the lamp holder 101, it is engaged and fixed with the buckle cap 111. The second bayonet 115 at the lower end of the central axis 106 is engaged and fixed with the second block 116 in the buckle cap 111, so that the components are engaged and connected in the longitudinal direction. In the above structure, the central axis 106, the rotating seat 109, and the buckle cap 111 form a coaxial double buckle structure, which is tightly and firmly combined and will not loosen. Moreover, the entire assembly process is completed by hand, 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 106 and the rotating seat 109 to rotate synchronously. The adjusting seat 110 and the lamp holder 101 are fixed. When the rotating seat 109 rotates, the spring clamp 112 interacts with the adjustment grid 119 by elastic force. When the rotating seat 109 stops rotating, the top of the spring clamp 112 is snapped into the corresponding adjustment grid 119, thereby achieving the rotational positioning of the adjustment grid 119. The light source body 102 can be flexibly adjusted to meet different usage requirements. In this embodiment, the light source body 102 can be rotated 290 degrees left or right.
[0032] The snap-fit structure is highly convenient to install, enabling quick 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 in large-scale production lines or 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. Precisely designed bayonet and latch blocks 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 generally 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 removable nature of the snap-fit structure provides 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, the product style design is also not restricted, and the design range is wide. The snap-fit structure can also achieve hidden connection, making the product appearance more simple and beautiful. In addition, the waterproof damping ring 122 integrates waterproofing and damping, effectively simplifying the structure, and has a high waterproof coefficient and high safety performance.
[0033] The utility model realizes a simple and reasonable structure and ingenious design. The central axis 106, the rotating seat 109, and the buckle cap 111 form a coaxial double-buckle structure, which is tightly and firmly combined and will not loosen. The entire assembly process is completed by hand, without the need for screws or additional tools. The assembly efficiency is high, the number of parts is small, the processing procedures are effectively simplified, and the material and transportation costs are saved. The appearance is simple and beautiful, the product size design and style design are not restricted, the design range is wide, and waterproof and damping are integrated, which further simplifies the structure and improves the waterproof coefficient and safety performance of the lamp's rotation adjustment structure.
