Please refer to Fig. 1 to Fig. 12, which shows the structure of the embodiment selected for the present invention. This is for illustrative purposes only and is not limited by this structure in the patent application.

The present embodiment provides a drawer locking assembly for a cabinet. As shown in FIG. 1 , the cabinet 1 is surrounded by a back panel 11 and a plurality of side panels 12 on the top, bottom and sides of the back panel 11 . And having an opening 13 on the opposite side of the backboard 11 for the plurality of drawers 2 to be inserted into the cabinet 1 , the drawer latching assembly is attached to the back panel 11 in the cabinet 1 for locking The drawer 2 is in the cabinet 1, the drawer lock assembly comprises a linear slide rail 3, a plurality of guide members 4, a moving member 5 and a blocking member 6, wherein:

As shown in FIGS. 1 to 3, the linear slide 3 includes a rail seat 31 and a slider 32. The rail mount 31 is longitudinally disposed on a longitudinal base 14 of the back panel 11. The slider 32 can be The rail seat 31 is longitudinally slidably disposed.

As shown in FIGS. 1 to 3, the plurality of guide members 4 are disposed on the slider 32 and respectively correspond to a drawer 2, and each of the guide members 4 has an upper convex portion 41 and a lower convex portion 42, the upper convex portion. There is a sliding groove 43 between the lower convex portion 42 and the lower convex portion 42 for the corresponding drawer 2 to be placed on the rear side of the stopper rod 21, and the upper convex portion 41 has a stopper rod 21 inserted into the sliding groove 43. Upwardly supporting the guiding surface 411 of the slider 32, and the lower convex portion 42 has a guiding surface 421 for pressing the slider 32 downwardly when the blocking lever 21 slides out of the sliding slot 43, and The upper convex portion 41 has a blocking surface 412 on the rear side which is located at a blocking position of the blocking lever 21 when the sliding bar 32 is pressed down.

As shown in FIGS. 4 to 5, the moving member 5 is fixed to the top end of the slider 32; the blocking member 6 is disposed at the top end of the longitudinal base 14 and corresponding to the moving member 5, and the blocking member 6 is When the slider 32 slides longitudinally, the displacement of the moving member 5 is blocked, and the slider 32 is temporarily positioned after the stopper 21 supports or presses the slider 32.

As shown in FIGS. 4 to 5, the moving member 5 of the present embodiment has a bottom plate 51 fixed to the top end of the slider 32, and the bottom plate 51 has a first tooth portion 52 facing the blocking member 6 and having a tapered shape. The first tooth portion 52 has an upper abutting surface 521 and a lower surface 522. The blocking member 6 has a positioning seat 61 fixed to the top end of the longitudinal base 14, and a thimble 62 is laterally disposed in the positioning base 61. The ejector pin 62 is pressed by an elastic member 63 to be retractably supported in the direction of the moving member 5, and the ejector pin 62 has a second tooth portion 64 facing the end of the moving member 5, and the second tooth portion 64 has a When the slider 32 is erected, it abuts against the upper surface 641 of the lower surface 522, and the second tooth portion 64 has a lower surface of the upper surface 521 when the slider 32 is pressed down. Meet 642.

As shown in the second to fifth embodiments, the bottom plate 51 of the embodiment has two protrusions 511 on one side facing away from the blocking member 6, and the two protrusions 511 are on the other side and the other is on the bottom, and the two are spaced apart. An accommodating space 512 is formed at a distance, and the accommodating space 512 is disposed on the lock lever 15 disposed on the cabinet 1 to be inserted relative to the protruding portion 151 to restrict the slider 32 from being depressed. When not being propped up.

As shown in FIGS. 4 to 5, when each of the drawers 2 is locked in the cabinet 1, the blocking portion 151 of the lock lever 15 is inserted into the accommodating space 512 to position the slider 32. By rotating the lock lever 15, the blocking portion 151 can be moved out of the accommodating space 512, so that the slider 32 can be freely moved up and down.

When a certain drawer 2 is withdrawn from the cabinet 1, as shown in the sixth to the ninth, the lever 21 slides out from the inside of the sliding slot 43 as the drawer 2 slides, and the lower convex portion 42 The lower guiding surface 421 moves along the blocking lever 21, and the sliding bar 32 is pressed down until the blocking lever 21 completely slides out of the sliding slot 43; as shown in Figures 10 to 12, in the blocking When the rod 21 is gradually slid out from the inside of the sliding groove 43, the sliding member 32 is pressed down by the guiding member 4, and the moving member 5 is pressed against the second tooth portion by the lower blocking surface 522. 64 above the blocking surface 641 to gradually drive the blocking member 6 originally blocking the moving member 5 to retreat, and when the lower blocking surface 522 is separated from the upper blocking surface 641, the blocking member 6 is subjected to the elastic member 63 Pressing, the lower abutting surface 642 is pressed against the abutting surface 521 of the moving member 5, so that the sliding bar 32 is temporarily maintained in a depressed state, at this time, except for the drawer 2 of the cabinet 1 being withdrawn. The rear side of the drawer 2 is blocked by the blocking surface 412 of the convex portion 41 of the guiding member 4 on the rear side of the drawer 2, and the cabinet 1 can no longer be withdrawn.

On the other hand, when the drawer 2 pulled out of the cabinet 1 is moved back into the cabinet 1, since the slider 32 is at the height of the pressed state, when the lever 21 enters the chute 43 again, the When the blocking rod 21 contacts the upper guiding surface 411 of the upper convex portion 41 and enters the sliding groove 43 from the outside of the sliding groove 43, the sliding bar 32 is guided to lift the sliding bar 32 from the pressed state. At this time, the lower abutting surface 642 of the blocking member 6 is disengaged from the upper abutting surface 521 of the moving member 5, and is returned to block the lower surface 522 of the moving member 5 with the upper blocking surface 641 thereof, so that the drawer 2 is Revert to the state in which the cabinet 1 can be withdrawn.

From the above description, it is not difficult to find that the present invention has the advantage that the linear slide rail 3 is disposed in the longitudinal base 14 in the cabinet 1, and the plurality of guide members 4 are disposed on the slide bar 32 of the linear slide rail 3, And the moving member 5 coupled to the slider 32 interacts with the blocking member 6 to temporarily maintain the sliding bar 32 in the pressing or supporting state, so that the drawer locking assembly of the conventional cabinet is compared. In other words, it is easy to assemble, easy to assemble, and easy to lock.

The above description of the embodiments is intended to be illustrative of the present invention and is not intended to limit the scope of the present invention.

From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the aforementioned objectives, and has been in compliance with the provisions of the Patent Law, and has filed a patent application.
