The working principle is as follows: as shown in fig. 1, 5, and 6, when the guide rail is closed, the return slider 23 and the rebound slider 29 return, and the rebound tension spring 5 is in a stretched state. Meanwhile, the reset hanging needle 31 on the inner rail is hung and buckled in the hanging and buckling groove 27 of the reset hanging block 26, the locking effect on the inner rail is achieved, the drawer is prevented from being opened under the non-operation condition, therefore, the tightness of the closed drawer is favorably kept, and dust and other sundries are prevented from entering the drawer.

When the drawer needs to be opened, a user presses the drawer to force the movable inner rail to move inwards, the reset hanging needle on the inner rail pushes the reset sliding block 23 to move towards the rebound sliding block 29, and the pressing gap between the reset sliding block 23 and the rebound sliding block 29 is compressed. When the reset slider 23 moves to a certain extent in the direction of the rebound slider, the reset slider contacts the push rod 57. When the reset slider continues to move, the pushing rod 57 is forced to move backwards, so as to push the first pushing rod 64 in the linkage mechanism 6 to move towards the direction of the synchronizing shaft and drive the synchronizing shaft to rotate. In the rotating process of the synchronizing shaft, the synchronizing shaft on the other side is synchronously driven to rotate through a connecting rod outside the synchronizing shaft, so that the guide rails on two sides of the drawer are synchronously unlocked. Simultaneously with the rotation of the synchronizing shaft, the second driving platform on the synchronizing shaft pushes the second push rod 65 to move reversely, so as to push the swing arm 66 to perform a yawing action. During the swing of the swing arm 66, the first slide groove 69 provided on the third push rod 68 via the driving column 67 thereon moves, thereby driving the third push rod 68 to move linearly.

As shown in FIG. 6, when the track is closed, the head of the third push rod 68 extends into the swing stroke of the trigger 58, and a limit stop 691 provided on the head of the third push rod 68 is disposed below the trigger 58 to limit the swing stroke of the trigger 58. At this time, the trigger is in a horizontal state, and the guide post 53 of the rebound catch block 52 catches on the trigger to lock the relative position between the rebound slider and the housing. When the drawer is pressed to be closed, the third push rod 68 moves, the limit platform 691 arranged on the head of the third push rod is separated from the trigger, the trigger loses the limit and deflects, and therefore the trigger is separated from the rebound hanging block, and the rebound hanging block and the rebound sliding block lose the limit. The rebound hanging block and the reset slide block move outwards under the action of the rebound tension spring 5, so that the outer rail is pushed to be opened outwards by the reset slide block and the rebound slide block.

In the opening process of the reset sliding block, under the action of the rebound tension spring, the reset hanging block 26 on the reset sliding block is forced to move from the guide slide rail 24 to the tripping slide rail 25, when the reset hanging block enters the tripping slide rail, the reset hanging block deflects, and the needle hanging groove on the reset hanging block is separated from the reset hanging needle, so that the guide rail can be completely opened, and the effect shown in fig. 10 is achieved.

When the guide rail is closed, the user pushes the guide rail backwards with force, the rebounding hook mechanism 4 on the inner rail is in contact with the rebounding locking block 56 on the rebounding hanging block 52, and the user pushes the rebounding sliding block 29 to move backwards and reset during the process of pushing the guide rail backwards with force, and the rebounding hanging block 52 is separated from the rebounding hook 44 on the rebounding hook mechanism 4 until the rebounding hanging block 52 deflects and is buckled with the trigger 58 again. The guide rails continue to close inwardly. When the guide rail is opened, the rebound slider stretches the return tension spring 51 and the rebound tension spring 5 to generate elasticity in the process of moving, so that the guide rail is opened in a rebound mode and closed in an automatic reset mode.

When the guide rail is closed to a certain stroke, the reset hanging needle 32 on the outer rail collides with the reset hanging block 26, and the reset hanging block 26 is forced to swing from the inside of the tripping slide rail 25 into the guide slide rail 24. The hanging and buckling groove 27 on the reset hanging block 26 is buckled with the reset hanging needle 32 again. After the reset hanging block 26 deflects, the reset hanging block 26 loses the traction effect on the reset slider 23, the reset slider 23 and the reset hanging block 26 move towards the closing direction under the action of the reset tension spring 51, and in the process of moving backwards, the guide rail is pulled to be completely closed through the linkage effect of the reset hanging block 26 and the reset hanging needle 32.

Wherein, it is required to be noted that: the sliding plate 41 is provided with a plurality of blocks which are in butt joint in front and back and are distributed on the side wall of the inner rail 13 in parallel, and each sliding plate 41 is provided with a rebound hook 44. Therefore, the side wall of the outer rail in the scheme is provided with the plurality of rebounding hooks 44 which are distributed at equal intervals, so that when the guide rail is opened to the opening degree and closed inwards, the rebounding hooks 44 can be in butt joint with the rebounding hanging blocks 52 on the rebounding slide block 29 in time to push the rebounding slide block to reset. Therefore, when the guide rail is not required to be closed every time, the guide rail is required to be opened to the maximum stroke, the rebounding hook 44 is forced to exceed the maximum stroke of the rebounding hanging block 52, the guide rail can be pushed backwards, the rebounding hook is forced to be hooked with the rebounding hanging block, and then the rebounding slider can be pushed to reset. Therefore, the drawer can be conveniently closed by a user at any opening degree, the reset of the rebound slider can be realized, and the use of the user is greatly facilitated.

Compared with the prior art, the structure in this case has presses the bounce-back and opens the function, can promote user operation impression and furniture grade, and during the guide rail, has the automatic re-setting function simultaneously for the drawer can the automatic operation to the closed condition, and the guide rail closes the back, has self-locking function, consequently when carrying furniture, the drawer can not open automatically, so can extensively use widely.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
