Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
Referring to Fig. 1, Fig. 2, the buffer unit of this furniture slide rail, comprises and determines slide rail 7 and moving slide rail 8, determines to be fixedly installed fixed mount 1 on slide rail 7, is provided with travelling carriage 2 on fixed mount 1, on travelling carriage 2, rotates and is provided with snap close 6; On moving slide rail 8, be fixedly installed slide block 5, on slide block 5, being provided with slotted eye 5.1 touches and is connected in the time that moving slide rail 8 closes to LAP with the upper convex portion 6.1 of snap close 6 upper surface settings, snap close 6 bottom surfaces are provided with lower protuberance 6.2, and turn over and sink to determining the hole portion 7.1 arranging on slide rail 7 and being separated with slotted eye 5.1 in the time that moving slide rail 8 opens to LAP.
Specifically, the rotating shaft 6.3 of snap close 6 be parallel to determine the horizontal plane of slide rail 7, perpendicular to the symmetrical centre face of determining slide rail 7, and be flush-mounted on the fitting recess 2.1 of travelling carriage 2 and the two is rotationally connected.The front end face of the corresponding slide block 5 of snap close 6 is provided with crashproof portion 6.4, when moving slide rail 8 cuts out, is connected with the crashproof portion 6.4 of snap close 6 by slide block 5.On moving slide rail 8, be provided with pilot hole 8.1, the corresponding pilot hole 8.1 of slide block 5 is provided with assembling auxiliary section 5.2, the two secure fit, and the moving corresponding slide block 5 of slide rail 8 is also provided with open slot 8.2.Determine to be provided with groove position 7.2 on slide rail 7, fixed mount 1 is fixed on groove position 7.2; On fixed mount 1, be provided with dovetail groove 1.1, the corresponding dovetail groove 1.1 of travelling carriage 2 is provided with flank 2.2, and the two is slidably matched.
In said structure, on travelling carriage 2, be provided with return unit, return unit one end is connected with travelling carriage 2, and the other end is with fixed mount 1 or determine slide rail 7 and be connected; Described return unit is reset damper 3 and/or back-moving spring 4.Specifically, on travelling carriage 2, be provided with the return unit of two, be respectively reset damper 3 and back-moving spring 4; The cylinder body of reset damper 3 is flush-mounted on fixed mount 1, and the end of its piston rod is flush-mounted on travelling carriage 2, and the two ends of back-moving spring 4 are individually fixed on fixed mount 1 and travelling carriage 2, makes slide rail 8 steady, smooth and easy in the time opening and closing.
