Fig. 9 is the perspective schematic view of rack 202 according to an embodiment of the invention.
In some embodiments of the invention, a pair of of rack 202 in lazy-tongs is respectively provided with along the front end of pull-out direction
There is anodontia section 202a, when shifting sledge 102 is drawn out to extreme position forward with respect to sliding rail rack 101, to make a pair of of gear
201 depart from a pair of of rack 202 in anodontia section 202a.It that is to say, in the case where pulling out limiting condition, gear 201 can be with respect to rack 202
It is moved along multiple directions, from the limitation of tooth form engagement.
In the prior art, when forceding back towards sliding rail rack 101 after shifting sledge 102 is drawn out again, since a pair is mobile
Lateral separation between slide 102 is generally large, therefore is easy to the nonsynchronous phenomenon of two wood side-guides occur.In the prior art,
Understand by carrying out the synchronization of slide to slide increase by 201 rack 202 of meshed gears combination always, but in this case,
If the gear 201 and rack 202 and the gear 201 of opposite side and the position of engagement of rack 202 in certain one side be not corresponding, can aggravate
The asynchrony phenomenon of slide or even it is damaged slide.
The lazy-tongs of the present invention after shifting sledge 102 is pulled out from sliding rail rack 101, to be connected with the two respectively
Gear 201 and rack 202 do not engage, the rack 202 not rotation of limiting gear 201 or moving direction.Work as shifting sledge as a result,
102 when being pushed into sliding rail rack 101 again, and the engagement of 201 rack 202 of a side gear or contact position can be with another side gears
The position of 201 racks 202 is adjusted.More precisely, the engagement of two side gears, 201 rack 202 or contact position can be mutual
Influence is mutually adjusted, so that lazy-tongs realize that engagement locating self-adjustable is whole.
Specifically, if since thrust is uneven slide is made to generate inclination, make the gear 201 on one side shifting sledge 102 first
It is engaged in the gear 201 on opposite side shifting sledge 102 with rack 202, the rack 202 of the engagement side can be in gear 201
Rotation direction generates certain resistance and it is prevented to be rotated further when having deflection.At this point, due to another side gear 201 not with rack
202 engagements, therefore will not be subject to resistance, so as to be relatively easily rotated further until another side gear 201 also with rack
202 occur engagement and with having occurred and that meshed gears 201 is located at same lateral position before this.Position after self-adjusting
In same lateral position two gears 201 can in the case where keeping meshing state, by connecting rod 203 rotate synchronously to
The rear end of rack 202, thereby guarantee that two wood side-guides slide synchronism, avoid two wood side-guides push-in initial position (namely
It is the extreme position pulled out) asynchronous and 201 rack of gear, 202 position of engagement the problem of can not corresponding to for generating.
The lazy-tongs for slide of the present invention can be used for synchronous both sides tooth in the push-in initial position adjustment of slide
The position relationship of 201 corresponding racks 202 is taken turns, so that two side gears 201 remain same in the push-on process of slide
Heart shaped state, it is ensured that the synchronous operation of two wood side-guides.
In some embodiments of the invention, the rear end of a pair of of rack 202 along pull-out direction is both provided with anodontia section
202a, when shifting sledge 102 is urged rearwardly into respect to sliding rail rack 101 to extreme position, to make a pair of of gear 201 in no-teeth
Section 202a departs from a pair of of rack 202.It that is to say, the rear and front end per toothed rack 202 is respectively provided with anodontia section 202a.The nothing of rear end
The effect of tooth section 202a is similar to the anodontia section 202a of front end.
Specifically, in the lazy-tongs of the prior art, when pull door body (or the drawer protecgulum for using slide guiding mobile
When structures) due to slide it is asynchronous and generate inclination when, shifting sledge 102 still can be in larger external force in some cases
Lower slider is promoted to the rear end of sliding rail rack 101.But since pull door body is always in heeling condition, when one side, door body is extensive
It is multiple to closed position when, opposite side door body can due to 201 rack 202 of gear side set and be turned off the conflict power of door body one side without
Method completely closes.The one side door body that is to say to be bonded with babinet 1 and opposite side door body can there are gaps between babinet 1.
Different from the prior art, the anodontia section 202a of 202 rear end of lazy-tongs rack of the invention allows gear 201
It moves freely or rotates, that is to say that the conflict power for being turned off door body one side can almost promote to be not turned off door body one side without resistance
Gear 201 is moved to the correct position of engagement, thus adjusts two side gears 201 to positioned at same lateral position, ensures both sides
Door body can normal switching-off.
In some embodiments of the invention, anodontia section 202a can be configured to the center of rotation when gear 201 in rack
When projection on 202 is located in the middle part of anodontia section 202a, gear 201 is allowed to be freely rotated.It that is to say, anodontia section 202a has
The space that gear 201 is allowed to be freely rotated in situ, so that gear 201 is by being freely rotated the dislocation realized in a lateral direction
Adjustment.
