As shown in the figure: the refrigerator slide rail that this is simple in structure; Rail 1, outer rail 2, ball retainer 3 and end position-arresting card 4 in comprising; The rail 1 interior rail upper plate 1.2 that the tip edge one of rail header board 1.1 connects and stretches out forward that included in described; Bottom edge at interior rail header board 1.1 is connected with the interior rail lower plate 1.3 of stretching out forward; Front surface head end portion at interior rail header board 1.1 is provided with end position-arresting card plate 1.4; Offer first section button hole 1.5 of slide rail at interior rail header board 1.1 with the radicals by which characters are arranged in traditional Chinese dictionaries section that is connected of interior rail upper plate 1.2, offer slide rail rear button hole 1.6, be integrally formed with slide rail hook 1.7 at the tail end upper surface of interior rail upper plate 1.2 at the connecting portion rear of interior rail header board 1.1 and interior rail upper plate 1.2; Slide rail hook 1.7 is arranged on the afterbody of slide rail rear button hole 1.6, and described slide rail hook 1.7 vertically stretches out towards interior rail upper plate 1.2 head end portions after upwards earlier; Have on the refrigerator slide rail of length direction road 1.8 under the raceway at the upper surface of interior rail lower plate 1.3, have raceway upper track 1.9 under the refrigerator slide rail of length direction at the lower surface of interior rail lower plate 1.3;
Described outer rail 2 is included in the outer rail upper plate 2.2 that stretches out backward of the top ends one connection of outer rail header board 2.1; The outer rail lower plate 2.3 of stretching out backward that one connects in the bottom of outer rail header board 2.1; Be fixed with at the back surperficial tail end of outer rail header board 2.1 and draw anti-slip salient point 2.4 outside the outer rail; On outer rail header board 2.1, offer external equipment installing hole 2.5; Lower surface at outer rail upper plate 2.2 has raceway upper track 2.6 on the refrigerator slide rail that is provided with along its length direction; Upper surface in outer rail lower plate 2.3 has along road 2.7 under the raceway under the refrigerator slide rail of its length direction setting, and the head end portion of outer rail upper plate 2.2 is toward the bending of outer rail lower plate 2.3 direction arcs, and the 2.3 head end portion upper surfaces of the outer rail lower plate in the road 2.7 have outer rail indentation locking salient point 2.8 under the raceway under the refrigerator slide rail;
The tip edge one that described ball retainer 3 is included in retainer header board 3.1 connects the retainer upper plate 3.2 that upwards stretches out; Bottom edge one at retainer header board 3.1 connects the retainer lower plate 3.3 of upwards stretching out; Retainer upper plate 3.2 is parallel with retainer lower plate 3.3; On retainer upper plate 3.2 and retainer lower plate 3.3, all offer ball hole 3.4, all offer retainer header board breach 3.5 in the inner end and the outer end of retainer header board 3.1;
Said end position-arresting card 4 is included in the interior rail lower plate slot of offering on the position-arresting card body 4.1 4.2; The tail end of interior rail lower plate slot 4.2 is an opening; Upside or downside at interior rail lower plate slot 4.2 offer end position-arresting card plate slot 4.3; The head end of position-arresting card body 4.1 is wedge shape, position-arresting card body 4.1 rear surface levels to top rib and basal edge position be equipped with 4.4, two rear wall inclined-planes 4.4, rear wall inclined-plane and be the clamping shape toward its rear end by its front end;
In inserting, the head end portion of interior rail lower plate 1.3 in the rail lower plate slot 4.2, in the end position-arresting card plate 1.4 insertion end position-arresting card plate slots 4.3, places ball in the ball hole 3.4;
On the refrigerator slide rail under the raceway on road 1.8 and the refrigerator slide rail raceway upper track 2.6 cooperate, under the refrigerator slide rail under raceway upper track 1.9 and the refrigerator slide rail under the raceway road 2.7 cooperate, in outer rail 2 is slidingly mounted on through ball retainer 3 and ball on the rail lower plate 1.3.
Tail end is provided with sliding limiting plate 1.10 outside the ball retainer in the back surperficial stage casing of interior rail header board 1.1.
The width of rail upper plate 1.2 is greater than the width of interior rail lower plate 1.3 in said.
Said end position-arresting card plate 1.4 is arranged on the front surface head end portion near the interior rail header board 1.1 of rail lower plate 1.3.
Described retainer upper plate 3.2 is perpendicular to retainer header board 3.1; Described retainer lower plate 3.3 is perpendicular to retainer header board 3.1.
Be on the same straight line in the center of circle of the ball hole on the retainer upper plate 3.2 3.4, and this straight line parallel and described retainer header board 3.1; Be on the same straight line in the center of circle of the ball hole on the retainer lower plate 3.3 3.4, and this straight line parallel and described retainer header board 3.1.
Rail lower plate slot 4.2 is communicated with one with end position-arresting card plate slot 4.3 in described.
Tip edge and the equal one of bottom edge at position-arresting card body 4.1 front faces are connected with the antetheca rib 4.5 of protrusion forward, and the length direction of said antetheca rib 4.5 is a horizontally set.
During use, on the rail 1, interior rail 1 was installed on the refrigerator doors with slide rail hook 1.7 through first section button hole 1.5 of slide rail, slide rail rear button hole 1.6 in outer rail 2 was slidingly mounted on through ball retainer 3.Be fitted with end position-arresting card 4 on the end position-arresting card plate 1.4; When outside outer rail 2, drawing; Retainer header board breach 3.5 positions of the head end portion of ball retainer 3 and end position-arresting card 4 bump against; The outer rail of outer rail 2 tail ends draws the anti-slip salient point 2.4 and retainer header board breach 3.5 positions of the tail end of ball retainer 3 to bump against outward, has limited the maximum outer of outer rail 2 and has drawn stroke, has limited simultaneously when drawing outside the outer rail 2 from interior rail slippage; When outer rail 2 indentations, the outer rail indentation locking salient point 2.8 of end position-arresting card 4 and the head end portion of outer rail 1 and arc kink 2.9 have combined to limit the maximum indentation stroke of outer rail 2.
Go up the rolling in the raceway upper track 2.6 on road 1.8 and the refrigerator slide rail under the raceway on the refrigerator slide rail of row's ball on the ball retainer 3; Following row's ball on the ball retainer is rolling in the road 2.7 under the raceway under raceway upper track 1.9 and the refrigerator slide rail under the refrigerator slide rail, makes outer rail 2 on interior rail 1, to slide.
During outer rail 2 indentations; For the tail end that prevents outer rail 2 knocks refrigerator, plug-in mounting end position-arresting card 4 on the end position-arresting card plate 1.4 of the head end portion of interior rail 1, end position-arresting card 4 is with after the end of outer rail upper plate 2.2 contacts; Arc kink 2.9 toward the bending of outer rail lower plate 2.3 directions forces end position-arresting card 4 to compress outer rail lower plate 2.3; After end position-arresting card 4 is through outer rail indentation locking salient points 2.8,, can not skid off easily again after making end position-arresting card 4 pass through outer rail indentation locking salient points 2.8 because arc kink 2.9 be an arc; Outer rail 2 has so just been limited the maximum indentation stroke of outer rail 2 by locking.
After when outer rail 2 indentations during locking, have end position-arresting card 4 that two rear wall inclined-planes 4.4 and head end be wedge shape position-arresting card body 4.1 and just can partly clamp-on on the refrigerator slide rail of outer rail 1 under the raceway upper track 2.6 and refrigerator slide rail under the raceway in the road 2.7.
