The present invention proposes a kind of linkage drawer sliding rail.
Referring to Figure 1 and Fig. 2, the linkage drawer sliding rail of the embodiment of the present invention includes the dynamic sliding rail 2 being connected with drawer and family
It is specifically connected to determine sliding rail 1 and be set to dynamic sliding rail 2 and determine the intermediate sliding rail 4 between sliding rail 1, dynamic 2 bottom of sliding rail and first
The clamping of retainer 3 is connected, and dynamic sliding rail 2 is connected by the first retainer 3 with the opposite sliding of intermediate sliding rail 4, determines at the top of sliding rail 1 and the
The clamping of two retainers 5 is connected, and is connected by the second retainer 5 with the opposite sliding of intermediate sliding rail 4 so that determining sliding rail 1, wherein intermediate
Sliding rail 4 is equipped with linkage mechanism 6, is equipped with Double-gear inside linkage mechanism 6 and is equipped with the first rack gear 31 with 3 bottom of the first retainer respectively
And second 51 engaged transmission of the second rack gear that is equipped at the top of retainer 5, and the top plate 41 of linkage mechanism 6 and intermediate sliding rail 4
It is connected with 42 grafting of side plate.
Fig. 3 to 5 is referred to, specifically, the linkage mechanism 6 of the present embodiment includes the internal fixed frame for being equipped with installation space
61, the inside of fixed frame 61 is equipped with the first gear 62 and second gear 66 for synchronizing and being axially driven, and 62 He of first gear
Mutually isolated by fixed frame intermediate bulkhead 67 between second gear 66, in addition 61 side of fixed frame will equipped with side enclosure 63
The axial end portion of first gear 62 surrounds, and 61 bottom of fixed frame is equipped with bottom enclosure 64 and wraps 62 bottom periphery of first gear
It encloses, top enclosure 65 is equipped at the top of fixed frame 61 and surrounds the top peripheral of second gear 66, at the same time first gear 62
At least top hollow out and with the engaged transmission of the first rack gear 31, at least bottom of second gear 66 be equipped with engraved structure and with the second rack gear
66 engaged transmissions, the top plate 41 of intermediate sliding rail 4 are equipped with top mounting holes 411 and are equipped with side mounting hole 421 in side plate 42, and
And top mounting holes 411 are connected to side mounting hole 421 and form installation slotted eye, fixed frame 61 can directly be plugged in installation slotted eye
It is interior, and fixed frame 61 contacts with the top plate 41 of intermediate sliding rail 4 and side plate 42 be connected simultaneously.
421 bottom edge of side mounting hole of the present embodiment offsets with 64 bottom surface of bottom enclosure of fixed frame 61, therefore passes through
Fixed frame 61 is inserted directly into the installation positioning for realizing 61 up and down direction of fixed frame in installation slotted eye.To realize fixed frame 61
It is more reliable between intermediate sliding rail 4 to be connected, the width of the side mounting hole 421 of the present embodiment along intermediate 4 extending direction of sliding rail
Less than the width of 411 corresponding direction of top mounting holes, and 61 side of fixed frame is provided with elastomeric element 68 and intermediate sliding rail 4
The clamping limit of 41 inner wall of top plate, and the front and back sides of elastomeric element 68 are limited by 421 edge of top mounting holes.Specifically,
The elastomeric element 68 of the present embodiment is opening up U-shaped elastomer block, U-shaped elastomer block side and 61 side stationary phase of fixed frame
Even, the end side elasticity of U-shaped elastomer block passes through top mounting holes 411 and offsets with 41 inner wall of top plate of intermediate sliding rail 4.
Preferably, in other embodiments of the invention, U-shaped elastomer block other side edge is equipped with upward-extending plate and is more than
41 top surface of top plate, so that in later maintenance, it is only necessary to by extension board to overturning in the middle part of fixed frame 61, enable fixed frame 61
Top mounting holes 411 are enough upward through, that is, linkage mechanism 6 may make to detach intermediate sliding rail 4 outward and be updated or safeguard.Separately
Outside, in other embodiments of the invention, the bottom enclosure of fixed frame 61 is wide at the top and narrow at the bottom skewed and pacifies with side
When filling the cooperation of 421 two sides edge of hole to be connected, therefore fixed frame 61 is inserted into from top to bottom inside installation slotted eye, pass through upper width
Under narrow incline structure, so that fixed frame 61 is more easily carried out centering when being connected with intermediate sliding rail 4 and guarantee installation relation more
It is reliable.
In addition, the second gear 66 of the present embodiment is fixedly linked with the one end for connecting splined shaft 69, connection splined shaft 69
After the other end passes through fixed frame intermediate bulkhead 67, then stretch in the centre bore of second gear 66,64 bottom sides of bottom enclosure
It is inserted into the limiting slot 52 of 5 side of the second retainer along lower limit block 641 is equipped with.
The present embodiment is arranged by top mounting holes 411 and side jointly by the top plate 41 and side plate 42 in intermediate sliding rail 4
The linkage mechanism 6 for being equipped with Double-gear is directly plugged in installation slotted eye in by the installation slotted eye that mounting hole 421 collectively constitutes
Between sliding rail 4 be connected, wherein being linked by the realization that offsets of 64 bottom surface of bottom enclosure of fixed frame 61 and 421 bottom surface of side mounting hole
About 6 mechanism positions, and is cooperated by top mounting holes 411 to elastomeric element 68 or side enclosure 63 and realizes gear
The front and back of structure 6 limits, then is clamped and is limited with top plate 42 after top mounting holes 411 by 68 elasticity of elastomeric element, final real
Existing linkage mechanism 6 is installed with the intermediate fastening of sliding rail 4, thus the present embodiment do not need compared with the prior art by two groups of positioning elements it
Between clipping room away from strict control, make to manufacture and install simpler and reliable.
Referring to Figure 1 to Fig. 6, in addition, the linkage mechanism 6 of the present embodiment while top plate 41 and side plate with intermediate sliding rail 4
42 connected realization installations only can be realized more reliable and secured by being clamped installation with single plate body compared with the prior art
Installation, and do not allow to easily cause siding that deformation occurs and influences the accurate of subsequent transmission in installation process.At the same time, this implementation
The end that the elastomeric element 68 of example is connected with 41 clamping of top plate of intermediate sliding rail 4 passes through positioning step slot first and realizes and top plate 42
Location and installation, and elastomeric element 68 can upwardly extend and be more than 41 top surface of top plate, and user can safeguard or more in the later period
When new, linkage mechanism 6 is set to pass through top mounting holes 411 by the elastomeric element 68 of compression or common clamping two sides, thus convenient
Maintenance and reduction use cost.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all at this
Under the design of invention, using equivalent structure transformation made by description of the invention and accompanying drawing content, or directly/it is used in it indirectly
He is included in scope of patent protection of the invention relevant technical field.
