Abstract

The present invention relates to a coupling/uncoupling assembly for a slide and a drawer, and more particularly, to a coupling/uncoupling assembly for a slide and a drawer, in which the slide is coupled to a bottom of the drawer. An engaging/disengaging assembly is secured to the bottom of a drawer near the front end thereof and is then used to engage the drawer to a slide that is approximately C-shaped in cross-section. The combining/separating assembly has one elastic column capable of being forced to move and one end of the elastic column has one wedge corresponding to the clamping hole. When the drawer is combined with the sliding rail, the elastic column is inserted into one end of the sliding rail, the wedge is clamped in a clamping hole close to the end of the sliding rail, and if the drawer is to be unlocked, the end of the elastic column is applied with force, so that the wedge is separated from the clamping hole, and the drawer and the connecting/disconnecting component can be separated from the end of the sliding rail.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A coupling/uncoupling assembly 100 for coupling a drawer to and uncoupling a drawer from a slide rail is shown in FIGS. 1 and 2 according to a preferred embodiment of the present invention. The connecting/disengaging assembly 100 includes a connecting plate 10 , a plug 20 , an elastic column 30 and a pressing portion 40 . The connecting plate 10 is provided with two oblique perforations 11, so when the connecting plate 10 is attached to a vertical wall of the panel of a drawer, the user can pass the screws through the two holes from the bottom of the drawer (combining/disengaging assembly 100). The holes 11 are punched obliquely to fix the coupling/uncoupling assembly 100 on the drawer.

The plug 20 includes a fixing portion 21 connected to the connecting plate 10 and an insertion portion 22 narrowed by the fixing portion, wherein a step 23 is formed at the junction of the fixing portion 21 and the insertion portion 22 . The fixing part 21 is further provided with two through holes 24, so that the coupling/uncoupling assembly 100 can be further fixed on the drawer by means of screws.

The pressing portion 40 includes a sliding plate 41 perpendicularly protruding from the elastic post 30 away from the plug 20 and a handle 42 located at an end of the sliding plate 41 .

The elastic post 30 includes a post body 31 and an enlarged wedge 32 at the end of the elastic post. The front end of the wedge 32 has an inclined surface 33, and three pairs of spaced abutting surfaces A, B, C are located behind the inclined surface. The three pairs of abutting surfaces are mutually symmetrical across the slide plate 41 .

A slide rail 50 adapted to cooperate with the coupling/decoupling assembly 100 is shown in FIGS. 2 and 3 . The slide rail 50 has a horizontal top plate 51, a first extending portion 52 protruding vertically from the top plate along one side of the top plate and having an L-shaped section, and a second extending portion symmetrical to the first extending portion located on the other side of the top plate 53, so the end of the slide rail has an opening 54 defined by the horizontal top plate, the first extension and the second extension. The first extending portion 52 is further provided with a clamping hole 55 and a sliding slot 56 connected from the end of the slide rail to the clamping hole.

The combination/disengagement assembly 100 is made of plastic material (such as nylon), so when the elastic column 30 and the insertion portion 22 are simultaneously inserted into the opening 54 at the end of the slide rail 50 and a part of the sliding plate 41 of the pressing portion is When received in the slide slot 56 , the elastic column 30 elastically presses against the first extension portion 52 . When the elastic column 30 and the insertion part 22 continue to enter the slide rail 50, the step 23 of the plug 20 will contact the end of the slide rail 50, and the wedge 32 of the elastic column 30 will pop out of the clamping hole 55 of the slide rail, and at the same time a wedge of the wedge will The abutting surface A will contact the locking hole 55 adjacent to a hole wall of the sliding groove 56 , so the coupling/unlocking assembly 100 is coupled to the end of the sliding rail 50 . Due to manufacturing errors, the clamping hole 55 may be located farther from the end of the slide rail 50 than an ideal position. In this case, the coupling/uncoupling assembly 100 can still be used, because B or C of the three pairs of abutment faces can still protrude beyond the catch hole 55 when the step 23 of the plug 20 touches the end of the slide rail 50 mesh with it.

The coupling/uncoupling assembly 100 that is coupled to the end of the slide rail 50 can be easily untied, including pushing the handle 42 toward the direction of the insertion portion 22, so that the wedge 32 is disengaged from the locking hole 55, so that the The coupling/uncoupling assembly 100 can be withdrawn from the opening 54 at the end of the slide rail 50 .
