Below with reference to a kind of pull assembly 1 of Fig. 1-Fig. 2 description according to first aspect present invention embodiment.
According to the pull assembly 1 of the embodiment of the invention, comprise the first tooth bar 11a and the second tooth bar 11b, the first slide rail 12a and the second slide rail 12b, the first gear train 13a and the second gear train 13b, and synchronizing bar 14.
As shown in Fig. 1 and Fig. 2, the first tooth bar 11a and the second tooth bar 11b extend along fore-and-aft direction respectively.Among the first slide rail 12a and the second slide rail 12b each include outer rail 121 and with respect to outer rail 121 movably in rail 122, and the first slide rail 12a and the second slide rail 12b extend along fore-and-aft direction respectively.
The first gear train 13a and the second gear train 13b correspondingly are installed in respectively on the interior rail 122 of the first slide rail 12a and the second slide rail 12b, for example on the interior rail 122 of the first slide rail 12a and the second slide rail 12b, be respectively equipped with axis hole, among the first gear train 13a and the second gear train 13b each comprises at least two gears of engagement successively, comprises last gear 131 that is positioned at rearmost end and the front gear that is positioned at last gear 131 front sides at least in two gears at least.Be understandable that, front gear 132 described herein is so long as be positioned at the gear of last gear 131 front sides and get final product, for example when the first gear train 13a or the second gear train 13b comprise at least three gears, front gear 132 can be the gear that is positioned at front side, also can be the gear in the middle of being positioned at.
Wherein last gear 131 and first a tooth bar 11a of its respective side and an engagement among the second tooth bar 11b, so that motion and interior rail 122 the moving synchronously with respect to outer rail 121 of last gear 131 on tooth bar, particularly, the last gear 131 among the first gear train 13a and the first tooth bar 11a mesh and other gears and 131 engagements of last gear and unsettled (promptly not meshing with the first tooth bar 11a), and last gear 131 among the second gear train 13b and second tooth bar 11b engagement, and other gears and 131 engagements of last gear and unsettled (promptly not meshing) with the second tooth bar 11b.
The two ends of synchronizing bar 14 are connected so that the synchronized movement between the first gear train 13a and the second gear train 13b with front gear 132 among the first gear train 13a and the second gear train 13b respectively.That is to say, by synchronizing bar 14, make motion and last gear 131 in two gear train 13bs and the synchronized movement second tooth bar 11b between of last gear 131 between the first tooth bar 11a among the gear train 13a that wins, so that the slide rail of both sides moves forward and backward simultaneously, improve motion along the slippage degree, reduce rocking of causing because the motion of two wood side-guides is inconsistent.To sum up, in the first gear train 13a or the second gear train 13b, have only a gear to be connected respectively, and have a gear to be meshed in addition with the tooth bar of respective side with synchronizing bar 14.
Thus, as shown in Figure 1, when the user applies forward pulling force respectively to the interior rail 122 of the first slide rail 12a and the second slide rail 12b, interior rail 122 travels forward with respect to outer rail 121, the last gear 131 of the first gear train 13a and the second gear train 13b travels forward on the first tooth bar 11a and the second tooth bar 11b respectively simultaneously simultaneously, when last gear 131 arrive its corresponding sides tooth bar foremost the time, reach its range according to the pull assembly of the embodiment of the invention.Otherwise the pull assembly retracts to its minimum stroke to the interior rail 122 of the first slide rail 12a and the second slide rail 12b along moving then in the other direction.
Perhaps, when on synchronizing bar 14, applying moment of torsion automatically by motor, the front gear 132 that synchronizing bar 14 drives the first gear train 13a and the second gear train 13b rotates, front gear 132 drives last gear 131 and travels forward on the tooth bar of respective side, when last gear 131 arrive its corresponding sides tooth bar foremost the time, reach its range according to the pull assembly of the embodiment of the invention.Otherwise applying when moving in the other direction then on synchronizing bar 14, the pull assembly retracts to its minimum stroke.
Thus, with respect to traditional be the pull mode of same synchromesh gear with tooth bar meshed gears and the gear that is connected with synchronizing bar, stroke according to the pull assembly of the embodiment of the invention has extended, and the lengthening distance is made as D, suppose that two centre-to-centre spacing after the gears engaged are d, each number of gears that comprises among the first gear train 13a and the second gear train 13b is n, then the * d of the distance D of the stroke of pull assembly lengthening=(n-1).Pull assembly according to the embodiment of the invention, the synchromesh gear group that comprises at least two gears by employing, and with tooth bar meshed gears and the gear that is connected with synchronizing bar is not same, movement travel can effectively extend, solved much the defective of the various inconveniences that cause inadequately owing to movement travel, can avoid the drawer can not or to be inconvenient to take out when for example being used in the refrigerator pull drawer according to the pull assembly of the embodiment of the invention.
In one embodiment of the invention, each among the first gear train 13a and the second gear train 13b comprises two meshed gears successively respectively.At this moment, pull assembly elongation distance D=(2-1) * d is a gear centre apart from d.
In another embodiment of the present invention, each among the first gear train 13a and the second gear train 13b comprises three meshed gears successively respectively, and wherein front gear 132 can be the gear that is positioned at front side, also can be the gear in the middle of being positioned at.At this moment, pull assembly elongation distance D=(3-1) * d is two gear centres apart from d.
In some embodiments of the invention, interior rail 122 is located in the outer rail 121 slidably by ball, and promptly the first slide rail 12a and the second slide rail 12b can be respectively ball slide rail.
