Working principle: as shown in fig. 6, when the guide rail is closed, the buffer frame is located at the tail end of the sliding seat, the tail end of the rebound slider is pressed against the pressing button 44, and a pressing gap is left between the tail end of the buffer frame 5 and the tail end of the sliding seat 4. At this time, the main fastening post 87 is fastened in the reset fastening groove 111 on the reset fastening 11 on the inner rail, and at this time, the reset fastening 11 is restrained by the reset tension spring 6 on the buffer frame 5, and the inner rail is locked. Therefore, when the drawer body moves, the drawer cannot be opened under the operation of no external force, and the tightness of the closed drawer is maintained.
When it is desired to open the guide rail, as shown in fig. 10, the inner rail is pressed inwardly, which pushes the rebound slide 8 rearward by the rebound catch 10 thereon, forcing the rebound slide 8 to push the main catch post 87 rearward, forcing the driving post 88 on the back of the main catch plate 86 from the sub catch groove 43 into the escape groove 431. The main buckle 86 deflects, so that the main buckle post 87 of the shifting needle is separated from the reset buckle 11 and the reset buckle groove 111. At this time, the rebound tension spring 81 provided between the rebound slider and the slide base 4 pulls the rebound slider to move in the rail opening direction. The inner rail is hung and buckled with the poking needle 85 on the rebound slide block 8 through the rebound buckling groove 101 on the rebound buckle 10, so that the rebound slide block can push the inner rail to open outwards when moving outwards, and the function of pressing and rebound opening of the drawer guide rail is realized. Therefore, when a user operates the drawer provided with the guide rail, after the user lightly presses the drawer body, the built-in rebound mechanism can eject the drawer for a certain stroke, so that the operation texture of the user is improved
As shown in fig. 11, when the rebound slider moves outwards, the setting pin 85 moves from the lock groove 51 to the reset groove 52, wherein the track of the reset groove 52 and the track of the self-lock groove 51 have a lateral difference, so that when the setting pin 85 moves to the reset groove 52, the setting pin is separated from the rebound catch groove 101, and the inner rail is opened continuously. After the rebound is finished, the user can drag the guide rail outwards to enable the guide rail to be completely opened. When the guide rail is completely opened, the push button 9 positioned at the tail end of the inner rail is hung with the main button column 87, and the rebound frame is pulled to be opened outwards by utilizing the power of the outward movement of the inner rail.
As shown in fig. 12 and 13, when the guide rail is opened to a certain extent, the push button 9 pulls the rebound frame to be opened to the maximum extent through the main button post 87, at this time, the driving post 88 at the lower end of the main button post 87 slides from the sub button slot 43 on the guide rail 41 to be separated from the separation slot 431 and locks the buffer frame, so that the main button post 87 moves laterally, the main button post 87 is separated from the push button 9, and the inner rail is completely opened.

At this time, the inner rail is locked by the hooking pin and the hooking groove 425, and the locking function after the guide rail is closed is achieved. When the user needs to open the guide rail again, the inner rail is pressed inwards, the inner rail pushes the hanging needle to separate from the buckling groove 425, the hanging needle is guided into the return groove 427 under the action of the return stop block 426, and the inner rail is bounced and opened again by the rebound slide block under the action of the rebound spring 81, so that the effect that the guide rail needs to be closed again under the condition that the guide rail is not completely opened after the user presses the guide rail to realize bounced and opened is realized.
In this embodiment, when the guide rail is normally closed, as shown in fig. 23, the hanging needle 84 enters the guide groove 428 from the parallel groove 421, when the guide rail is pressed by the user to rebound and open, the inner rail pushes the hanging needle 84 to enter the homing groove 430 from the guide groove 428, when the rebound slide block rebounds and opens, the hanging needle is dragged to enter the guide groove 429 from the homing groove 430 to realize rebound and opening, when the drawer is pulled outwards continuously by the user to realize full opening of the guide rail, the hanging needle enters the parallel groove 421 from the guide groove 429 to realize full opening of the guide rail, and the track of the hanging needle moves 1, 2, 3 and 4 as shown in fig. 23.
When the guide rail is not fully opened by the user after the guide rail is pressed and rebounded, as shown in fig. 24, and when the guide rail needs to be closed at this time, the user only needs to push the guide rail inwards again, and pushes the rebounded sliding block to move inwards by using the inner rail, so that the hanging needle is forced to enter the hanging hook groove 432 from the position (4) of the guiding groove 429 and is hung and buckled in the hanging hook groove 433. At this time, the inner rail is locked by the hooking pin and the hooking groove 433, and the locking function after the guide rail is closed is achieved. When the user needs to open the guide rail again, the inner rail is pressed inwards, the inner rail pushes the hanging needle to separate from the hook groove 433, the hanging needle is guided into the unhooking groove 434 under the action of the return stop block, after the user loosens the hand, the inner rail is bounced and opened again by the rebound slide block under the action of the rebound spring 81, the hanging needle enters the homing groove 430 from the unhooking groove 434 under the dragging of the rebound slide block, then enters the guiding groove 429 into the parallel groove 421, and the movement track of the hanging needle moves in the direction of 4-5-6-7-8. The effect of needing to close the guide rail from a new state is also realized under the condition that the guide rail is pressed by a user to realize rebound opening and is not completely opened.
