Ceiling Lighting Device Sliding Lock Mechanism

The patent replaces the traditional screw-based mechanical adjustment system with a push-button actuated system. The push button (23) connects to a rod (24) that moves laterally to engage or disengage from grooves (19) in the lighting body (17), eliminating the need for screws and screwdrivers while maintaining reliable positioning.

The lighting body (17) features self-aligning grooves (19) that automatically engage with the rod (24) when the push button is actuated. The grooves are positioned to guide the rod into place, allowing the system to self-lock without requiring precise manual alignment or complex adjustment procedures.

The patent divides the fixing mechanism into independent functional elements: the push button (23), the rod (24), and the grooves (19). This segmentation allows the rod to be independently actuated to release the lighting body, enabling maintenance without disassembling the entire fixture while maintaining secure locking during operation.

The rod (24) is designed as a separate, movable component that can be independently extracted or actuated through the push button mechanism. This allows the locking function to be engaged or disengaged without removing the lighting body or disassembling the frame, facilitating easy maintenance and replacement.

The patent combines multiple positioning functions into a single rod (24) that engages with grooves (19) at different locations. Actuating one push button (23) simultaneously controls the rod's lateral movement, which in turn engages or disengages all positioning points at once, eliminating the need to adjust multiple individual screws sequentially.

The grooves (19) are pre-positioned in the lighting body (17) at the exact locations where positioning is required. The rod (24) is designed with corresponding engagement features that automatically align with these pre-positioned grooves, ensuring precise positioning is achieved instantly upon actuation without requiring iterative adjustment.
