The sliding rail of the embodiment is used as a sliding rail of a drawer, and the working principle is as follows:
in the closed state of the drawer, the rebound device 34 and the buffer seat 35 are connected together by buckling the buckling column 3412 of the movable buckle 341 with the buckling groove 351, as shown in fig. 18.
When the drawer is required to be opened, the drawer panel is pressed first, the drawer drives the movable rail 2, the movable rail 2 pushes the rebound device 34 to slide backwards through the trigger switch 4, so that the buckling column 3412 of the movable pulling buckle 341 is separated from the buckling groove 351 and slides into the right guide groove 3510, then under the action of the elasticity of the spring 37, the rebound device 34 is separated from the buffer seat 35 and slides forward rapidly, meanwhile, the buckling column 3412 of the movable pulling buckle 341 slides out of the right guide groove 3510, in the forward sliding process of the rebound device 34, the column 381 of the coupling piece 38 is placed in the trigger channel 41 of the trigger switch 4, when the boss 382 slides to the side of the stop position 3111 at the front end of the guide groove 311, the rebound device 34 is abutted against the guide rod fixing seat 312 at the front end of the base 31, the rebound device 34 stops sliding, and the movable rail 2 automatically opens the drawer under the bouncing action of the rebound device 34, as shown in fig. 19. When the drawer is pulled further in the opening direction, the movable rail 2 continues to drive the trigger switch 4 to move forward, at this time, the coupling member 38 interacts with the post 381 in the trigger channel 41 to swing around the post 3421, so that the boss 382 is clamped into the stop position 3111, the rebound device 34 is kept at the original stop position, the trigger switch 4 pushes the pull rod fixing seat 36 to slide forward through the hook 362, the hook 362 slides on the convex strip 10, so that the pull rod 33 pulls the buffer seat 35 and the unidirectional rotation buffer 39 to close to the rebound device 34, when the buckling post 3412 of the movable buckle 341 contacts with the second inclined surface structure 3511 of the buffer seat 35, the second inclined surface structure 3511 guides the buckling post 3412 of the movable buckle 341 to slide in from the left guide groove 3510, the buckling post 3412 slides along the left guide groove 3510 to slide into the buckling groove 351 again to buckle with the buckling groove, meanwhile, the hook 362 also slides to a position at the avoiding hole 11, at this time, the hook 362 falls into the avoiding hole 11 under the action of the elasticity of the torsion spring 363 to separate from the trigger switch 4, the rebound device 34, the buffer seat 35 and the pull rod fixing seat 36 are all in a stop state, as shown in fig. 20, after that, the drawer drives the movable rail 2, the trigger switch 4 and the middle rail 5 to slide forwards continuously until the drawer is completely opened. Since the unidirectional rotation damper 39 is unidirectional damping, the unidirectional rotation damper 39 has no damping effect during the drawer opening process, and thus, the drawer opening process is smooth.
When the drawer is closed, the movable rail 2 drives the trigger switch 4 to slide backwards, when the trigger switch 4 slides to the position of the rebound device 34, the column 381 of the coupling member 38 slides back into the trigger channel 41, and swings around the column 3421 backwards due to the interaction of the trigger channel 41 and the column 381, so that the boss 382 is separated from the stop position 3111 and returns to the guide slot 311, at this time, under the rebound action of the inner spring 371, the rebound device 34 and the buffer seat 35 keep the connected state together and slide backwards under the driving of the pull rod 33 to return to the position contacting with the guide rod fixing seat 312 at the rear end of the base 31, and the pull rod fixing seat 36 also slides backwards to the position contacting with the guide rod fixing seat 312 at the front end of the base 31, and simultaneously, the rebound device 34 drives the movable rail 2 to slide backwards simultaneously through the trigger switch 4 and the coupling member 38, so that the drawer is automatically closed at the rear closing section. Since the gear 391 of the unidirectional rotation damper 39 is meshed with the rack 310 on the base 31 to generate a damping effect, the damper seat 35, the rebound damper 34 and the movable rail 2 slide backward slowly, so that the drawer moves slowly and smoothly in the closing direction until being completely closed in the rear closing section, thereby achieving the damping function.
The embodiments of the present invention described above do not limit the scope of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit principles of the present invention should be included in the scope of the claims of the present invention.
