Upwards it is communicated with gathering sill；Be installed in fixing seat after A gear and the assembling of B gear, and by salient point and
Turn hole locating rotation.
Described A gear and B gear stretch out in fixing seat up and down.
Described gear mechanism is inserted on middle rail in the gear hole arranged；Fixing seat front and back end is provided with hook portion
Rail inwall in buckling.
Described upper rack is fixed in active rail, and lower tooth bar reciprocates between middle rail and retaining rail.
The present invention arranges gear mechanism, and gear mechanism includes A gear and B gear, is respectively adopted many
Limit shape post and polygonal hole closely cooperate assembling, and when active force is more than certain value, polygonal hole is magnified,
Two gears rotate relative to skidding, and when active force is less than certain value, two gear synchronous rotate, this change,
Ensure that two gears intermesh in correct position with upper lower tooth, adapt to the needs of slide rail different phase, have
Imitate protects wheel and rack, and the opening and closing with drawer in season is more smooth and easy.It has simple and reasonable,
Assembling is simple, dependable performance, the feature of length in service life.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
Seeing Fig. 1, this is for the gear mechanism 3 of slide rail, including mutually nested active rail A, middle rail B and
Retaining rail C, is provided with upper rack 1, is provided with between middle rail B and retaining rail C between active rail A and middle rail B
Lower tooth bar 2；Being engaged with gear mechanism 3 between upper rack 1 and lower tooth bar 2, gear mechanism 3 arranges two gears and divides
Nie He upper rack 1 and lower tooth bar 2；Two gears use polygon posts and polygonal hole to closely cooperate assembling,
Active force is more than certain value, and two gears rotate relative to skidding, and active force is less than certain value, two gear synchronous
Rotate, it is achieved active rail A is run with the synchronization of middle rail B or dislocation, it is ensured that two gears coordinate with upper and lower tooth bar
Again can be in correct position.Thus slide rail can be continuing with again three joint synchronous effect and functions, tooth bar,
Gear is hardly damaged.
Seeing Fig. 2-3, gear mechanism 3 includes A gear 3.1 and the B of band polygonal hole of band polygon post
Gear 3.2, also includes the fixing seat 3.3 for fixing two gears.Polygon post on A gear 3.1 is inserted
It is located at the polygonal hole of B gear 3.2, to realize closely cooperating assembling, and is coaxially disposed, the most polygon
Shape post is correspondingly arranged with polygonal hole, i.e. limit number is identical.The polygonal hole of B gear 3.2 is being rotated
When power is more than certain value, naturally magnify, make A gear 3.1 skid with B gear 3.2 and rotate.
Fixing seat 3.3 is logical in being, inwall left and right sides is coaxially respectively arranged with salient point 3.31 and turns hole 3.32,
Its transfer hole 3.32 is upwards communicated with gathering sill, first A gear 3.1 and B gear 3.2 is assembled, then
Integral installation is in fixing seat 3.3, and passes through salient point 3.31 and turn hole 3.32 locating rotation.A gear
3.1 and B gears about 3.2 stretch out in fixing seat 3.3.
Seeing Fig. 4-6, gear mechanism 3 is inserted on middle rail B in the gear hole a arranged；Fixing seat 3.3
Front and back end is provided with hook portion 3.33 rail B inwall in buckling.
Seeing Fig. 7, upper rack 1 is fixed on active rail A inner roof wall, and lower tooth bar 2 is placed in middle rail B with solid
Reciprocating between orbit determination C, gear mechanism 3 is placed between upper and lower tooth bar, and A gear 3.1 and lower tooth
Wheel 2 engagement, B gear 3.2 engages with upper rack 1.By effect active rail A, make gear mechanism 3
Receive revolving force effect, and reach different effects according to the size of revolving force.
