The guide rail buffer device adopts the hydraulic piston structure to realize the buffer function with the hydraulic oil, effectively buffer and counteract the resilient force during closing the drawer, thus the closing of drawer can be more smooth, less impact force, no noise caused by collision, with high safety and reliability; the guide rail buffer device can be used for wide range of acting forces, no high damping force and drawer unclosed state caused, and a widely application is provided.
Description
Technical field
The utility model relates to the guide rail technology, particularly a kind of guide rail buffer unit.
Background technology
Existing guide rail comprises orbit determination, moving rail, slide assemblies, resilience mechanism, orbit determination is connected by slide assemblies with moving rail, orbit determination is fixed on the locating rack, moving rail is fixedly mounted on the drawer, between orbit determination and moving rail, be provided with resilience mechanism, when closing drawers arrives certain position, drawer can be closed under the effect of resilience mechanism automatically, but, resilience mechanism can produce collision because spurring when drawer springs back to the end, cause sound, particularly the sound that causes when the pulling force of resilience mechanism is big is bigger to user's influence.In order to overcome this shortcoming, provide a kind of " guide rail that has buffer unit " in the patent No. for 02227175.9 Chinese utility model, feature is that a fixed head is set on retaining rail, buffer unit is installed on fixed head, movable rail is provided with a catch, one magnet is set, the cooperating of catch with magnet on buffer unit; Described buffer unit is pneumatic type structure or spring structure, and the buffer unit of described pneumatic type structure is made up of overcoat, movable post, piston, rubber ring, end cap; The buffer unit of described spring structure is made up of overcoat, movable post, spring, end cap; The action principle of this guide rail is: when drawer is closed to certain position, the catch that is provided with on the movable rail is run into the magnet and the adhesive of buffer unit, under the pulling of resilience mechanism, movable rail drives drawer moves in buffer unit, because the plenum space that in buffer unit, forms or the cushioning effect of spring, slowed down the translational speed of movable rail, up to whole drawer is closed; The buffer unit of this guide rail can be implemented in the process that the automatic resilience of drawer closes its buffering is avoided sending the sound, but also there is shortcoming and defect in its structure: wherein the buffer unit of pneumatic type structure is owing to only rely on the air column in the overcoat to produce cushioning effect, so its cushion effect that can provide is less, buffering effect is relatively poor, for the guide rail that uses the bigger resilience mechanism of pulling force and inapplicable; And for the buffer unit of spring structure, its cushioning effect that provides realizes by spring, the active force of spring is opposite with the active force of guide rail resilience mechanism, thereby slow down its rebound velocity, this structure cooperates with active force between the resilience mechanism for spring has relatively high expectations, if the active force of spring is bigger, the active force of resilience mechanism is less then can not realize closing of drawer, if the active force of spring is too small, the active force of resilience mechanism is bigger, the buffering effect of being realized is also relatively poor so, and closing velocity is fast, and impulsive force is big; In addition, this guide rail not only needs to install buffer unit, also needs to cooperate location and installation magnet, magnet and buffer unit mating reaction could realize its effect purpose with buffer unit.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of simple, good buffer effect, little, safe and reliable guide rail buffer unit of impulsive force installed is provided.
The purpose of this utility model is achieved through the following technical solutions: this guide rail buffer unit is installed on the orbit determination of guide rail, with be fixed on moving rail on the catch effect of matching, comprise oil cylinder cover, oil cylinder spring, piston, piston rod, described oil cylinder spring and piston are arranged in the oil cylinder cover, oil cylinder spring one end apical grafting is inboard at the oil cylinder cover, other end apical grafting is on piston, and described piston is connected with the piston rod that passes the oil cylinder cover.
Be provided with the passage that is communicated with piston two end spaceses in the described piston.
Be provided with sealing ring between described piston and the oil cylinder cover.
The end that described piston rod is positioned at the oil cylinder cover is connected with card, is used to prevent that piston rod from skidding off in the oil cylinder cover.
Be provided with sealing ring between described oil cylinder cover and the piston rod.
The end binding that described piston rod stretches out the oil cylinder cover has cushion pad.
This guide rail buffer unit can be applicable to have two joints or the three joint drawer guideways of automatic resilience function.
Action principle of the present utility model is: when drawer is closed to certain position, under the pulling of resilience mechanism, catch on the moving rail that is connected with drawer contacts with piston rod, the motion in the oil cylinder cover of pushing piston bar, piston rod roof pressure piston simultaneously overcomes the slip in the oil cylinder cover of the interior oil pressure of oil cylinder cover, oil in the oil cylinder cover overlaps an end spaces by the passage in the piston from oil cylinder simultaneously and flow to other end space, the speed that pressure oil provides the damping opposite with the drawer closing direction that drawer is closed in process of flowing simultaneously slows down, thereby realizes the purpose to its buffering; When drawer was opened again, piston slowly resetted again under the rebound effect of oil cylinder spring, and the pressure oil in the oil cylinder cover also backflows by the passage in the piston simultaneously.
The utility model has following advantage and effect with respect to prior art: this guide rail buffer unit adopts the fluid pressure type piston structure, utilize hydraulic oil to realize buffering, because hydraulic oil can provide bigger damping, so can cushion counteracting preferably to the active force of closing drawers or drawer resilience, make drawer close mild more suitable cunning of closed procedure, impulsive force is little, can not send sound because of collision, and is safe and reliable; The situation that damping force causes drawer not close greatly can not take place in active force wider range that this guide rail buffer unit is suitable for, and adaptive surface is wider.
