Referring to fig. 1 to 9, the working principle of the rebound mechanism with synchronous start-stop in the present embodiment is as follows:
when the drawer is in the closed state, the tail end of the hook 5232 movably connected with the anti-falling member 5231 extends into the second sliding track groove 512, the tail end of the hook 5232 is clamped on the left arc surface of the limit projection 5124, the synchronous stop block 534 is downwards clamped into the positioning clamping groove 5211 of the first triggering member 521, so that the triggering member 52 and the synchronous member 53 are connected to form an integral structure, and meanwhile, the positioning groove 528 at the right lower corner of the triggering member 52 and the positioning groove 528 at the right lower corner of the fixing member 51 are respectively clamped with the end part of the tension spring 59, and the tension spring 59 is in the maximum stretching state.
When the user needs to directly withdraw the drawer outwards, the user only needs to apply an outwards pulling force to the drawer, so that the drawer drives the movable slide rail 2 to outwards move, and the starting piece connected with the movable slide rail 2 is directly clamped into the gap between the trigger piece 52 and the rebound stop block 529 when the drawer is in a closed state. When the user directly pulls out the drawer, because the two sides of the top end of the rebound stopper 529 are respectively inclined surfaces, the starting piece can move upwards along the inclined surface of the top end of the rebound stopper 529, and the rebound stopper 529 downwards overcomes the rebound spring 5292, accordingly, the end of the rebound guide pin 5291 passing through the middle part of the rebound stopper 529 slides into the avoidance track groove 5111 from the horizontal track groove 5112, the starting piece can smoothly pass through the rebound stopper 529 in a straight line and outwards move from the gap between the triggering piece 52 and the rebound stopper 529, and the user can conveniently pull out the drawer. When the user needs to push the drawer into the furniture body for resetting, the user only needs to directly apply inward thrust to the front panel of the drawer, so that the starting piece gradually moves towards the gap between the trigger piece 52 and the rebound check block 529, the starting piece compresses the rebound check block 529 to move towards the avoidance track groove 5111 through the inclined surface at the top end of the rebound check block 529, and therefore the drawer can be smoothly clamped into the gap between the trigger groove 526 of the trigger piece 52 and the rebound check block 529 through the rebound check block 529, and the drawer drawing function is normally used when the rebound function is not needed by the drawer.
When the user needs to eject the drawer outwards through the rebound function, the front panel of the drawer is pushed towards the inner direction of the drawer, so that the movable slide rail 2 moves a small distance towards the inner part of the furniture body along with the drawer. When the drawer is in a closed state, the starting piece connected with the movable slide rail 2 is clamped into a gap between the triggering groove 526 of the triggering piece 52 and the rebound stop block 529, the starting piece is propped against the triggering groove 526 of the triggering piece 52, a user pushes the triggering piece 52 to move inwards by pushing the drawer, and then the tail end of the hook 5232 is propped against the first inner wall surface 5125 and moves upwards continuously to slide into the first horizontal track groove 5121. Because the drawer is in the maximum tension state when the drawer is in the closed state, the tension springs 59 of the trigger piece 52 and the fixing piece 51 are respectively tensioned, and after the tail end of the hook 5232 slides into the first horizontal track groove 5121, the trigger piece 52 loses the clamping action of the hook 5232, the tension springs 59 rapidly contract and deform, and then the trigger piece 52 is pulled to move towards the right end of the fixing piece 51 rapidly, when the trigger piece 52 moves towards the right side of the fixing piece 51 rapidly, the end of the rebound guide pin 5291 is clamped into the first sliding track groove 511, and when the rebound guide pin 5291 moves from the horizontal track groove 5112 to the inclined track groove 5113 which is inclined downwards, the rebound guide pin 5291 drives the rebound stop 529 to move downwards, so that the trigger piece 52 applies rapid outward pushing force to the trigger piece, and the trigger piece is released from the gap between the trigger groove 526 and the rebound stop 529 to move outwards rapidly, and correspondingly, the trigger piece also pushes the movable slide rail 2 to move outwards due to the inertia effect, namely the drawer gradually pops outwards, and moves outwards, the tail end of the hook 5291 moves from the horizontal track groove 5112 to the inclined downwards, and the hook moves from the first horizontal track groove 5112 to the second horizontal track groove 5123, and the second horizontal track 5123 can move further from the first horizontal track groove 5123.
During the movement of the trigger 52 toward the right end of the fixed member 51 by the tension spring 59, since the synchronization stopper 534 of the synchronization member 53 is engaged downward into the positioning groove 5211 of the first trigger 521 by gravity in the initial state, the trigger 52 is moved rightward together with the synchronization member 53, but when the synchronization member 53 is moved rightward, the synchronization guide pins 535 which were engaged into the fourth sliding track groove 514 and the fifth sliding track groove 551 are moved from the synchronization horizontal track groove 5141 to the synchronization inclined track groove 5142, so that the synchronization guide pins 535 are also moved upward to release the engagement relationship with the positioning groove 5211. In the process of moving the synchronizing member 53 from the synchronizing horizontal track groove 5141 to the upward-inclined synchronizing inclined track groove 5142, the rack 531 at the lower part of the synchronizing member 53 is meshed with the gear at the end of the synchronizing gear member 56, so that the synchronizing gear member 56 is correspondingly sleeved with the synchronizing rod connecting member 58 for transmission, and finally, the sliding rails 1 mounted on two sides can realize synchronous operation through the synchronizing rods 6 arranged in the middle position.
When the drawer moves outwards to the limit position through the rebound function, a user only needs to apply continuous inward pushing force to the front panel of the drawer, because the end part of the rebound guide pin 5291 is clamped into the tail end of the inclined track groove 5113, and the positioning slide block 527 slides in cooperation with the third sliding track groove 513, the rebound stop 529 compresses the rebound spring 5292 and is at the lowest position, the starting piece can conveniently prop against the trigger groove 526 without compressing the rebound stop 529, and accordingly, the starting piece also pushes the trigger piece 52 to gradually move towards the left side of the fixed piece 51 along with the continuous movement of the movable slide rail 2, the tension spring 59 with two ends respectively clamped into the trigger piece 52 and the fixed piece 51 is gradually stretched, meanwhile, the tail end of the hook 5232 slides into the leftwards end position of the second horizontal track groove 5122 along the third inner wall surface 5127, after the user releases the pushing action to the drawer, the starting piece 59 has a reset trend, and accordingly, the trigger piece 52 is pulled to move towards the left side of the fixed piece 51, the corresponding hook 5224 is also pushed out of the inclined track groove 5122 from the corresponding groove 5124, the position of the hook 5232 is completely stretched out of the inclined track groove 5113, and the hook 5232 is completely stretched out of the position of the inclined track groove 5113, and the limit groove 5124 is completely matched with the hook 52, and the limit groove 5124 is completely stretched out of the position of the inclined track groove 5113, and the limit groove is completely stretched. In addition, the trigger piece 52 will also push the synchronous piece 53 to move to the left side during the left movement, the synchronous guide pin 535 will also move to the left side from the right end of the fifth sliding track groove 551, the synchronous stop 534 will be snapped into the positioning slot 5211 of the first trigger piece 521 again under the action of gravity, so as to realize that the synchronous piece 53 is connected with the trigger piece 52 again, the synchronous gear piece 56 meshed with the rack 531 at the lower part of the synchronous piece 53 will also move to the left side from the right side, the synchronous gear piece 56 will also drive the synchronous rod connecting piece 58 to rotate correspondingly, thus the working process opposite to the action during the outward movement of the drawer will occur, and the slide rail 1 at the left and right sides can realize the synchronous recovery action.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the specification and drawings of the present invention or direct/indirect application in other related technical fields are included in the scope of the present invention.
