  As shown in FIGS. 3 to 10, according to the automatic closing device for the built-in drawer slide rail of the present invention, the drawer slide rails are at least the inner slide rail 1, the middle slide rail 2, the outer slide rail 3, and the inner slide rail 1. And a second slide inner bush 20 provided between the middle slide rail 2 and the outer slide rail 3. The above-mentioned inner slide rail 1 is attached to a predetermined position (not shown) of the inner side wall 4 (FIG. 4) of the space for accommodating the drawer of the cabinet, and the upper side of the outer slide rail 3 is below the drawer 5. Once connected, the drawer 5 is pulled outward and pushed inward.

  The automatic closing device includes an interlocking block 31, an automatic closing slide hook 6, and an automatic closing sheet 7.

  The interlock block 31 is fixed to the outer slide rail 3, and the interlock bar 311 is located at a predetermined height of the side wall 32 of the outer slide rail 3.

  The automatic closing slide hook 6 is fixed to one side 601 of the spring 60.

  The automatic closing sheet 7 is fixed to a predetermined portion of the bottom end surface 13 of the inner slide rail 1.

  When the outer slide rail 3 is moved backward together with the drawer 5, the interlocking rod of the interlocking block 31 provided thereon drives the 311 automatic closing slide hook 6 and the automatic closing slide hook 6 slides. In conjunction with the rail 3, the spring 60 automatically recovers rearward by the force of the spring 60, thereby achieving the effect of automatic closing.

The features of the present invention are as follows.
The automatic closing slide hook 6 is provided with a front guide post 61 and a rear guide post 62 on one side, and is pivotally mounted in a slide groove 701 provided on an adjacent wall surface on one side of the slide groove 70 of the automatic close sheet 7. 8 and 9, the automatic closing slide hook 6 slides back and forth in the sliding groove 70 of the automatic closing sheet 7, and a guide slope 63 inclined forward and downward is provided on the front side thereof. Is provided with a positioning groove 64, and a positioning hook 65 is separately extended downward at the bottom on the rear side to be connected to one side 601 of the spring 60, and further connected to the automatic closing sheet 7 by the spring 60. ing.

  The automatic closing sheet 7 has a sliding groove 70 in the same direction as the reciprocating direction of the drawer 5 in the front-rear direction, and a sliding groove 701 in the same direction is provided on an adjacent wall surface on one side in the sliding groove 70. A stopper surface 7011 is provided on the rear side, a lower positioning sliding groove 7012 bent downward is extended and formed on the front side, and a hook 7013 is provided on an adjacent side wall on the rear side of the sliding groove 701 so that the spring 60 The other side 602 is locked and positioned, and a stopper surface 702 is provided on an upper portion near the rear side of the slide groove 701 to be used for contact above the rear end surface 66 of the automatic closing slide hook 6. .

  Due to the above-described feature, when in the closed state, the rear guide post 62 of the automatic closing slide hook 6 is blocked by the stopper surface 7011 on the rear side of the sliding groove 701 of the automatic closing sheet 7 (FIG. 8), and the automatic closing slide is performed. The upper end of the rear end surface 66 of the hook 6 is blocked by the stopper surface 702 on the rear side of the sliding groove 70 of the automatic closing sheet 7, and the interlocking rod 311 of the interlocking block 31 of the outer slide rail 3 engages with the positioning groove 64 of the automatic closing slide hook 6. Located within. When the drawer 5 is pulled out with the outer slide rail 3, the interlocking block 31 drives the automatic closing slide hook 6, and the automatic closing slide hook 6 is moved by the front guide column 61 and the rear guide column 62 to close the automatic closing sheet 7. When the front guide column 61 reaches the front side of the slide groove 701, the slide rod 701 slides forward into the lower positioning slide groove 7012, the rear side of the automatic closing slide hook 6 rises, and the front The guide column 61 is positioned in the lower positioning slide groove 7012 (FIG. 9), and the interlocking rod 311 of the outer slide rail 3 is separated from the positioning groove 64 of the automatic closing slide hook 6 and continuously slides forward. Conversely, when the drawer 5 is returned to the original position rearward with the outer slide rail 3, the front side of the interlocking rod 311 contacts the front side of the automatic closing slide hook 6 and its positioning recess along the guide slope 63. The front end of the automatic closing slide hook 6 rises, and at the same time, the front guide column 61 on the front side thereof is moved downward to slide into the lower positioning sliding groove. It slides upward along 7012 to disengage from the positioning of the lower positioning slide groove 7012 and slides toward the rear side of the slide groove 701 by the elastic recovery force of the spring 60, and the rear guide post 62 slides the slide groove 701. , And the automatic closing function is achieved.

  Further, the lower part of the slide groove 70 of the above-mentioned automatic closing sheet 7 presents a downward open state, and a sealing part 703 having an appropriate area is provided above and behind the sliding groove 70 to increase the positioning effect of the spring 60 and to remove the spring 60 during use. To prevent.

  Further, the lower end of the lower positioning sliding groove 7012 that is bent downward and extended in front of the sliding groove 701 of the automatic closing sheet 7 communicates with the bottom end surface 74 of the automatic closing sheet 7 to exhibit a downward open state. It is convenient to attach the automatic closing slide hook 6 of the front guide pillar 61 and the rear guide pillar 62 at the time of attachment.

The present invention has the following functions.
