Detailed description of the invention
Below in conjunction with accompanying drawing, concrete further instruction is done to the utility model.The concealed synchronous guide track of a kind of novel three joint, it comprises the outer rail 1 be set with successively, middle rail 2 and interior rail 3, interior rail 3 will be provided with pearl frame 4 with middle rail 2, middle rail 2 will be provided with lower pearl frame 5 with outer rail 1, upper and lower pearl frame is provided with ball and needle roller and plays the effect that supporting guide slides, it is characterized in that: between described upper pearl frame 4 and lower pearl frame 5, have gear teeth wheels 6, gear teeth wheels 6 engage with upper pearl frame 4 upper rack 41 and with the lower tooth bar 51 that lower pearl frame 5 is arranged, and gear teeth wheels 6 are fixed on middle rail 2.
Described gear teeth wheels 6 comprise pedestal 61 and rotating shaft 62 provided thereon, rotating shaft 62 are rotatably mounted with the first different gear 63 of the number of teeth by shaft coupling and the second gear 64, two gear engages with upper rack 41 and lower tooth bar 51 respectively.
The first described gear 63 and the gearratio of the second gear 64 are 0.6:1.
Described pedestal 61 both sides are provided with fast-assembling buckle 65 and are fastened with the mounting groove 21 be arranged on middle rail 2.
Described fast-assembling buckle 65 is provided with two, is symmetrically distributed in pedestal 61 both sides.
Described upper pearl frame 4 upper rack 41 is one-body molded, and lower pearl frame 5 is one-body molded with lower tooth bar 51.
Described upper rack 41 and corresponding first gear 63 of lower tooth bar 51 and the second gear 64 front-back staggered are arranged.
Operation principle: in this case, upper pearl frame 4 and lower pearl frame 5 are respectively arranged with upper rack 41 and lower tooth bar 51, and wherein in order to strengthen the stability of product and reduce production cost, the tooth bar in this case and pearl frame adopt integrative-structure to make.
In the guide rail of traditional common, due to outer rail, middle rail, and interior rail adopts the structure of wrapping up successively, after therefore going up pearl frame and lower pearl frame and guide rails assembling, its internal structure reality is for have misplaced up and down.Therefore be subject to the impact of this structure, directly between upper and lower pearl frame, gear synchronous device can not be installed.Therefore the concealed synchronous guide track occurred on the market all needs to do larger change to the structure of itself, as interior rail, middle rail, outer rail Cross-section needs to avoid gear synchronous structure, also needs to arrange separately rack and pinion cooperation in addition and can realize its synchronizing function.Therefore structure, the manufacturing process complexity of this kind of concealed synchronous guide track, cause its research and development in early stage, later stage production cost is all relatively high.The most important thing is that its structure is different from existing concealed synchronous guide track, cause the spare and accessory parts of being correlated with can not be general, cause manufacturer to need design separately to produce relative part, give and produce, warehousing management be made troubles.
For the problem of prior art, propose new solution in this case, based on existing asynchronous hidden guide, rail in not changing, interior rail, under the prerequisite of outer rail structure, upper and lower pearl frame is integrally provided with upper rack and lower tooth bar with it.Because upper and lower tooth bar is front-back staggered structure by the impact of existing structure, therefore devise gear train structure cleverly in this case.Gear train is provided with and is connected to the first gear in same rotating shaft and the second gear, two gears engage with the first tooth bar and the second tooth bar respectively, and are quick installed on middle rail by buckle structure by gear train.The structure of Double-gear is solving while the dislocation of upper and lower tooth bar can not directly be engaged by individual gears, because gear train is fixed on middle rail, therefore can drive pearl frame during pinion rotation, lower pearl frame and the motion of middle rail simultaneously, thus realize three joint guide rail synchronizing functions.Solving traditional hidden guide can only the synchronous drawback of binodal.
In addition, in order to make in drawer guideway motion process, the middle rail that bearing capacity is stronger is protruding (when guide rail is protruding at first, just, rail and interior rail outwards move, and rail support force is weak in interior rail support force ratio), the first gear 63 on the gear train in this case and the gearratio of the second gear 64 are 0.6:1.Therefore guide rail is in motion process, and the movement velocity of middle rail can be faster than the movement velocity of interior rail, make it stretch out at first, thus to avoid in conventional synchronization guide rail that rail is consistent with middle rail movement velocity causes interior rail often stressed, affects its service life.Therefore can extensively promote the use of.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; as the setting of gear train gearratio, the syndeton etc. between tooth bar and pearl frame, these changes and improvements all fall within the scope of claimed the utility model.
