Description
Technical field
The utility model relates to the technical field of sliding rail, specifically a kind of mute sliding rail of multistage buffering.
Background technique
The three section sliding rails that existing drawer uses, function is simple, and comfort lacks, and opposite manufacturing cost is lower, due to price
Cheaply, by the favor of low end client.But this type sliding rail generally open and close drawer process there are biggish shocks
Noise, with the increase of number of use, sliding rail stability dramatic decrease, noise also comes bigger, and component is easily damaged, and leads to sliding rail
It cannot use, there is not being durable property and serious security risk.
For this purpose, there is a kind of novel double-damping structure sliding rail in the later period again, it is characterized in that double locking plates to double retainers simultaneously
It contacts and hits, due to retainer plastic cement material, in addition sliding rail space limits, although such double-damping structure can inhibit part
Noise, but it is not soft enough, and cushion stroke is also shorter, softly or is energetically occurring obvious noise under impact events, is keeping simultaneously
The decline of frame service life.So such double buffering sliding rail noise reduction effect is bad, service life is shorter.
With the development of sliding rail product, there is a kind of buffering holding frame sliding track with rack-and-pinion, such cunning again in market
Rail has certain reduction noise function, and stability is also relatively good, but there are following for this kind of double buffering rack-and-pinion synchronous sliding track
It is insufficient:
1) rack-and-pinion double buffering synchronous sliding track can not increase cushion stroke under spatial margins and equivalent material, use tooth
Wheel rack gear occurs shaking in its motion process, have some setbacks, and when buffering is unable to reach soft noise reduction effect, and impact noise is bright energetically
Aobvious, comfort level is obviously insufficient.
2) spare and accessory parts that rack-and-pinion double buffering synchronous sliding track uses increase, and manufacturing process is complicated, and cost is high, together
When there is also and there is gear bounce and drawer to occur when opening entirely jumping tooth, sweep tooth phenomenon under sliding rail loading condition, it is serious compared with
It is easy to appear gear breaking under hitting energetically, is reduced the service life.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of mute sliding rail of multistage buffering, knot
Structure is simple, in a limited space in increase cushion stroke and flexible multistage superposition buffering, reduce that active rail is opposite with middle rail to transport

Elastomer 41 and first end elastomer 42, to be formed with first breeze way.As active rail 3 continues to slide, as the first guarantor
After holding the first front end elastomer 41 and the first rear end elastomer 42 compression a small distance of frame 4, the second scotch of active rail 3
11 contact with the second front end elastomer 51 of the second retainer 5, the second rear end elastomer 52 and the middle rail 2 of the second retainer 5
4th limited block 9 contact, to be formed with successively superposition breeze way.Make to form multistage flexible in a limited space and be superimposed to delay
Punching increases cushion stroke in the confined space, realizes gradually multistage superposition buffering, effectively the double buffering side instead of hitting simultaneously
Formula, noise reduction and reduction stop collision vibrating effect are more significant.
Moreover, the first front end elastomer 41 of the first retainer 4 and the compression of the first rear end elastomer 42 and to limit process
When, the second front end elastomer 51 of the second retainer 5 is gradually superimposed with 52 bounce of the second rear end elastomer, is protected with protection first
Frame 4 is held, buffering effect is significant, and realizes and resist protection, promotes the durability and comfort of sliding rail, and simplify structure, reduces system
This is caused, strong applicability.
Shown in referring to Figure 2 to Figure 4, first retainer 4 is the first elastic shelf, after the first front end elastomer 41 and first
End elastomer 42 is integrally formed respectively in the front and rear end of the first elastic shelf；Second retainer 5 is the second elastic shelf, before second
End elastomer 51 and the second rear end elastomer 52 are integrally formed respectively in the front and rear end of the second elastic shelf.Moreover, described
One retainer 4 and the second retainer 5 are respectively equipped with the rolling column 17 and roller ball 18 being slidably connected with active rail 3 and middle rail 2, rolling
Dynamic column 17 and roller ball 18 are separately mounted to horizontal block and the left and right sides of the first retainer 4 and the second retainer 5.Improve structure
Stability promotes operation smoothness, it is ensured that sliding rail uses quality.
It is sliding equipped with the lower layer with bidirectional elastic between the middle rail 2 and the connection of retaining rail 1 shown in referring to Figure 2 to Figure 4
Retainer 12.Middle rail 2 is equipped with limited block 14 after lower layer's front limited block 13 and lower layer, and the sliding with middle rail 2 makes lower layer's front limit
Block 13 is connect with lower layer's front end elastomer 121 of lower layer retainer 12, or makes limited block 14 and lower layer's retainer 12 after lower layer
Bottom endwall elastomer 122 connects.Under the action of having lower layer's retainer 12 of bidirectional elastic, the slow of sliding rail is further increased
