Description
Technical field
The utility model relates to a kind of buffer unit of slide rail.
Background technology
People are difficult to control to the dynamics of pulling out or pushing back when pulling out or push back drawer, in order to solve the problem that dynamics was pulled out or pushed back in above-mentioned control, on the retaining rail of quite a few slide rail buffer are installed on the market.Movable rail is flush-mounted on the retaining rail and by buffer and retaining rail and flexibly connects, and promptly buffer is fixedly installed on the retaining rail and with movable rail and is connected, and buffer drive activity rail slides on retaining rail.Above-mentioned buffer is generally cylinder or oil cylinder, adopts bigger cylinder or the oil cylinder of volume to be installed on the retaining rail, and ability assurance activity rail slides stable on retaining rail, but adopts volume bigger cylinder or oil cylinder cost big.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, cost is low and the buffer unit of the slide rail of good buffer effect.
Goal of the invention of the present utility model is achieved in that a kind of buffer unit of slide rail, the back-moving spring that comprises pedestal on the retaining rail of being located at slide rail, is located at the buffer on the pedestal and is connected with buffer with pedestal respectively, it is characterized in that: described buffer is provided with the slide block that is connected with back-moving spring, pedestal is provided with the chute adaptive with slide block, described slide block is installed on the chute, described chute end has the locating slot that flexibly connects with slide block, and the movable rail of described slide rail is provided with the hook that pulls out of adaptive slide block active buckle.
Described slider bottom is provided with the mount pad that is flush-mounted on the chute, and back-moving spring one end is installed on the pedestal, and the other end is connected with mount pad.
Described slide block and mount pad interconnect by connecting pin.
Described slide block end is provided with the alignment pin that flexibly connects with locating slot.
Also be provided with the mounting groove of adaptive buffer setting-in between described pedestal and the chute, the drive lower bumper by slide block slides on mounting groove.
Described pedestal, chute, locating slot and mounting groove are that one is connected.
Described buffer is a cylinder.
The utility model improves the buffer unit of prior art slide rail, on buffer, be provided with the slide block that is connected with back-moving spring, pedestal is provided with the chute adaptive with slide block, described slide block is installed on the chute, described chute end has the locating slot that flexibly connects with slide block, and the movable rail of described slide rail is provided with the hook that pulls out of adaptive slide block active buckle.Be connected with the buckle that pulls out hook by slide block, realize that movable rail and retaining rail on the slide rail are locked mutually when drawer is in closed condition, improve safety in utilization; After the user pulls the drawer out, slide block with pull out hook and be in released state, because the slide block end is provided with the alignment pin that flexibly connects with locating slot, at this moment, alignment pin is buckled on the locating slot, when the user pushes back drawer, after group hook on the movable rail collided slide block, alignment pin broke away from locating slot immediately, and slide block is buckled in again and pulls out on the hook, drive down slowly inwardly propelling by buffer, the buffer unit of the utility model slide rail by improving structure, dwindles the driving cylinder volume that is installed on the pedestal greatly, the input that reduces cost improves buffering effect greatly.
Description of drawings
Accompanying drawing 1 is the structure principle chart of the utility model most preferred embodiment;
Accompanying drawing 2 is a structural representation of the present utility model;
Accompanying drawing 3 is the structure enlarged drawing of slide block.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
With reference to the accompanying drawings shown in 1 to 3, the buffer unit of slide rail of the present utility model, comprise pedestal 1, buffer 2, back-moving spring 3, slide block 4, chute 11, locating slot 12, alignment pin 42 and pull out hook 5, wherein pedestal 1 is flush-mounted on the retaining rail 6 of slide rail, buffer 2 and back-moving spring 3 are installed on the pedestal 1, and this buffer 2 is cylinder or oil cylinder.Buffer 2 is provided with the slide block 4 that is connected with back-moving spring 3, this slide block 4 is fixedly connected on the piston rod 21 of buffer 2, slide block 4 bottoms are provided with mount pad 41, slide block 4 and mount pad 41 interconnect by connecting pin 7, this connecting pin 7 is connected with slide block 4 one, back-moving spring 3 one ends are installed on the pedestal 1, and the other end is connected with mount pad 41.Pedestal 1 is provided with chute 11, and slide block 4 is flush-mounted on the chute 11 by mount pad 41.Chute 11 ends are located at by locating slot 12 and slide block 4 flexibly connects, chute 11 and locating slot 12 combinations are the J type, alignment pin 42 is located at slide block 4 ends, slide block 4 is connected for one with alignment pin 42, locating slot 12 is adaptive mutually with alignment pin 42, slide block 4 is connected with locating slot 12 by alignment pin 42, makes drawer under open mode by alignment pin 42 and locating slot 12, for slide block 4 provides positioning function.What the movable rail 8 of slide rail was provided with adaptive slide block 4 active buckles pulls out hook 5, and this pulls out hook 5 and is installed on the movable rail 8 by riveted joint or screw ways of connecting.Also be provided with the mounting groove 13 of adaptive buffer 2 setting-ins between pedestal 1 and the chute 11, the drive lower bumper 2 by slide block 4 slides on mounting groove 13.Pedestal 1, chute 11, locating slot 12 and mounting groove 13 are connected for one.When drawer is under the closed condition, promptly the retaining rail 6 of slide rail is connected with movable rail 8 ends, at this moment, pulls out hook 5 and is in buckle state with slide block 4.When the user pulled out drawer, slide block 4 was pulled out on chute 11 outward by pulling out hook 5, and alignment pin 42 was buckled in the locating slot 12 when slide block 4 arrived locating slots 12, and promptly slide block 4 is positioned on the locating slot 12, at this moment, slide block 4 with pull out hook 5 and break off relations, drawer is opened.When user's closing drawers, promptly movable rail 8 advances toward retaining rail 6 ends, at this moment, after dialling 4 collisions of 81 pairs of slide blocks of hook, alignment pin 42 breaks away from locating slot 12 immediately, and slide block 4 is buckled in again and pulls out on the hook 5, drive down slowly inwardly propelling by buffer 2 and back-moving spring 3, drawer is closed.The buffer unit of the utility model slide rail by improving structure, dwindles buffer 2 volumes that are installed on the pedestal 1 greatly, and the input that reduces cost improves buffering effect greatly.
