Abstract
The utility model discloses a drawer slide rail self-closing buffering device, which is easy to install and convenient to use. The drawer slide rail self-closing buffering device mainly comprises an upper guide rail, a lower guide rail, a slider, a boss and a buffering device, and is characterized in that the slider is provided with a rectangular groove corresponding to a rectangular projection on the boss; and when the drawer is pushed to a certain position, the projection on the boss on the lower guide rail cooperates with the groove in the slider, which pushes the boss to shift slowly by the action of a spring and a damping element, and the buffering self-closing is thus realized. The smart structure of the drawer slide rail self-closing buffering device enables the drawer to give out no noise during opening and closing without the utilization of any fastener.
Description
Technical field
The utility model relates to furniture buffer unit field, specifically is the self-closing buffer unit of a kind of drawer sliding rail.
Background technology
At home to open and close what pursue be comfortable to the switch of drawer, and the keying of drawer is enough to make its switch freedom smooth and easy with two pairs of guide rails that cooperate up and down, but very easily clash into when closing, and the generation noise, what is more because bump bounce-back and drawer is resetted fully, cause poorly sealedly, dirt is hidden in gas leakage.Be head it off, the Chinese utility model patent specification of the CN201316024Y that on September 30th, 2009 was announced discloses the self-closing buffer unit of a kind of drawer, noise when being used for reducing closing drawers, but the buffer unit complex structure that it provided, inconvenience is installed, and needs the securing member of similar bolt to be connected and installed.
The utility model content
Technical problem to be solved in the utility model provides a kind of installation process does not have any securing member, eliminate the self-closing buffer unit of drawer sliding rail of closing noise, good buffer effect.
For solving above technical problem, the self-closing buffer unit of a kind of drawer sliding rail described in the utility model comprises upper rail, lower guideway, boss and buffer unit, for solving above technical problem, a kind of drawer sliding rail buffer unit described in the utility model comprises upper rail, lower guideway, boss and buffer unit, buffer unit is connected with upper rail by self buckle, and boss passes through T type groove and is connected with lower guideway; Groove fit on boss and the slide block also moves with the elongated slot of slide block along undersetting; Upper bracket is connected with baffle plate by self buckle and has limited except that all frees degree along undersetting moves; End socket is fixed by snap on undersetting and slide block is enclosed in the elongated slot of undersetting; Slide block is connected on upper bracket by between centers crack, hole; The two ends of cylinder and spring are connected with lower carriage with upper bracket respectively; A rectangular recess is arranged on the slide block.
Buffer unit is made up of upper bracket, undersetting, end socket, cylinder, slide block and spring.
Duty lower spring length is greater than length under the nature.
When spring length was maximum, it can rotate along the deep-slotted chip breaker on the undersetting around the axle that is mated.
The below of boss has T type projection, and cooperates with opening on the lower guideway.
Adopt the drawer sliding rail buffer unit of this programme, when contacting with the protruding block of slide block, under the effect of spring tension owing to the roller on the lower guideway, slide block rotates around the upper bracket axle and along deep-slotted chip breaker, rectangular recess until slide block cooperates with the rectangular preiection of boss, and at this moment, slide block is under the effect of spring force, driving boss and drawer moves, along with the increase of displacement, spring force is gradually little, and damping action is obvious, thereby the buffering of realization, interference abates the noise.

The specific embodiment
Shown in Fig. 1 to 8, the self-closing buffer unit of drawer sliding rail described in the utility model comprises upper rail 3, lower guideway 13, boss 7 and buffer unit, and wherein buffer unit is made up of upper bracket 1, undersetting 2, end socket 4, cylinder 6, slide block 8 and spring 5.When promoting drawer, drawer drives connected lower guideway 13, lower guideway 13 drives boss 7 mounted thereto and moves, when the roller on the lower guideway 13 22 contacted with the protruding block 21 of slide block 8, under the effect of spring tension, slide block rotated around upper bracket axle 9 and along deep-slotted chip breaker 18, rectangular recess 11 until slide block 8 cooperates with the rectangular preiection 23 of boss 7, at this moment, slide block 8 drives boss 7 and drawer and moves under the effect of spring force.Along with the increase of displacement, spring force is gradually little, and damping action is obvious, thus the buffering of realization.When slide block 8 moves to certain distance, under the effect of end socket 4, stop to move, realize resetting.During the pull drawer, under the effect of external force (pulling power), drawer drives lower guideway 13 and boss 7 mounted thereto moves, and boss 7 drive slide blocks 8 move along the elongated slot 12 of undersetting 2.When moving to certain distance, slide block 8 rotates around upper bracket axle 9 and along deep-slotted chip breaker 18, thereby breaks away from boss 7, and drawer continues outer drawing.And the like, the buffering of realization drawer opening-closing process.
