Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lighting technology, specifically relating to an angle adjuster for lighting fixtures. Background Technology
[0002] Existing adjusters employ simple bushing or friction-based positioning structures, lacking a reliable meshing and fixing design. During long-term use, the adjusted angle is prone to shift due to the lamp's own weight, vibration, or changes in ambient temperature, causing the illumination position to deviate from the preset target. This problem severely impacts the user experience and display effect.
[0003] Existing regulators generally lack clear angle measurement markings, and the adjustment process relies on the user's subjective judgment or external auxiliary tools (such as protractors), making it impossible to intuitively obtain the adjustment angle parameters. For example, when adjusting a light fixture from 30° to 45°, the user can only estimate the angle by visually observing the light projection range, making it difficult to achieve precise positioning. Some regulators with coarse scales have excessively large scale intervals (e.g., each division represents 10°) and lack clear indicating components, still failing to meet the needs of scenarios with high angle accuracy requirements, such as medical lighting and precision instrument operation lighting.
[0004] Therefore, the shortcomings of existing lamp angle adjusters in terms of structural stability and adjustment accuracy have become a key bottleneck restricting the upgrading of lamp functions and scene adaptation. There is an urgent need to develop an angle adjuster that is structurally robust, precisely adjustable, and easy to operate in order to meet the usage needs of diverse lighting scenarios. Utility Model Content
[0005] This addresses the technical problems of poor structural stability and adjustment accuracy in existing angle adjusters.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an angle adjuster for a lamp, comprising an adjusting body and an adjusting cover. The adjusting body has protruding teeth on the surface facing the adjusting cover, and a scale portion is provided on the outer periphery of the teeth. The adjusting cover has protruding second teeth on the surface facing the adjusting body, and the second teeth engage with the teeth of the adjusting body. The adjusting cover has a scale indicator component disposed on the surface of the scale portion.
[0007] Furthermore, the inner side of the adjusting body is provided with a recessed groove, and the inner circumference of the adjusting cover is provided with a protruding positioning part, which is located in the recessed groove.
[0008] Furthermore, the main body and the cover are fixedly connected by fasteners.
[0009] The present invention has the following advantages: the adjusting body and the adjusting cover are connected by meshing teeth, making the structure of the adjuster more robust and stable; and the scale indicator component is located on the surface of the scale section, making the angle adjustment more precise.

[0015] like Figures 1 to 4 As shown, an angle adjuster for a lamp includes an adjustment body 10 and an adjustment cover 20. The adjustment body 10 has protruding teeth 11 on the surface facing the adjustment cover 20, and the outer periphery of the teeth 11 has a scale portion 12. The inner side of the adjustment body has a recessed groove 13.
[0016] The adjustment cover 20 has a raised second tooth 21 on its surface facing the adjustment body 10. The second tooth 21 engages with the tooth 11 of the adjustment body 10. The adjustment cover 20 has a scale indicator component 22, which is located in the scale portion 12. The inner circumference of the adjustment cover 20 has a raised positioning portion 23, which is located in the recessed groove 13.
[0017] In practice, the adjusting body 10 and the adjusting cover 20 are fixedly connected by fasteners. When the angle between the adjusting body 10 and the adjusting cover 20 needs to be adjusted, the fasteners between the adjusting body 10 and the adjusting cover 20 are loosened first, and the adjusting body 10 and the adjusting cover 20 can be rotated to adjust the angle. When the adjusting body 10 and the adjusting cover 20 are rotated, the positioning part 23 of the adjusting cover 20 rotates along the side wall of the recessed groove 13, making the rotation operation between the adjusting body 10 and the adjusting cover 20 more convenient. The scale indicator part 22 is provided on the surface of the scale part 12, so that the user can clearly see the angle parameters between the adjusting body 10 and the adjusting cover 20, making the angle adjustment more accurate. After the angle is adjusted, the fasteners between the adjusting body and the adjusting cover are fixed to complete the angle adjustment.
[0018] In summary, the angle adjuster of this utility model has a meshing connection between the adjusting body 10 and the adjusting cover 20 through teeth, making the structure of the adjuster more robust and stable. The scale indicator component 22 is provided on the surface of the scale part 12, making the angle adjustment more precise.
