Abstract
The utility model provides a double-layer type slide way of a desktop which is double-movable for drawing and extending, comprising a parent track, a first child track and a second track. The front of the parent tract is fixedly provided with a group of pulleys mounted with flexible line body, and the backs of the first and the second child tracks are provided with a first linking element and a second linking element which are respectively linked with the upper line section and the lower line section of the flexible line body. The utility model is mainly that the parent track is provided with a mounting slide slot which is bended and molded as a whole at the upside and the downside, and the first and the second child tracks are also provided with a first mounting flange and a second flange which are bended and molded as a whole at the upside and the downside and are matched with the mounting slide slot of the parent track. The first child track and the second child track move oppositely, the first and the second mounting flanges can displace stably along the mounting slide slot of the parent trace, thus, the mutually matched mounting slide slot and mounting flanges can be directly bended and molded at the parent tract and the child tracks, which does not require fixedly arranging a trolley additionally and achieves the practical benefits of saving cost and improving assembly convenience.
Description
Technical field
The utility model relates to a kind of fit chute and fit flange that can directly bending forming cooperatively interacts between female rail and first and second sub-rail, and can make the steadily slippage on female rail of first and second sub-rail, with effective saving cost and the two-layer equation slide rail that can two moving pulls extends desktops that promotes the assembling convenience.
Background technology
Now, furniture is the amplification desktop, be to be provided with a left side, right board, but and the flexible slide rail of a pull of arranging in pairs or groups, make a left side, right board can stretch out and increase the usable floor area of desktop, the mode of the table of slide rail drive at present start has single action to move with two general the branch, and the slide rail of two moving designs is divided into two laminar slide rails and three-layer type slide rail, with two two moving laminar slide rails, see also Fig. 1～Fig. 2, it is the rail structure improvement patent case of No. 85218199 adjustable table body of TaiWan, China patent application of the previous application of applicant, include C type slide track seat 10 and two L type travelling carriages 20,30, described C type slide track seat 10 is to be installed with gear 11 in front, and last, the inner face of below panel offers corresponding one group of roller guide groove 12 and one group of tooth bar guide groove 13, and two L type travelling carriages 20, the 30th, corresponding overleaf C type slide track seat 10 tooth bar guide grooves 13 positions are respectively equipped with the tooth bar 21 in order to be engaged on gear 11,31, and be provided with a plurality of rollers 22 in corresponding C type slide track seat 10 roller guide grooves 12 positions, 32, described two L type travelling carriages 20,30 can utilize roller 22,32 sliding putting on the roller guide groove 12 of C type slide track seat 10, and make tooth bar 21,31 insert in tooth bar guide groove 13, and be engaged on gear 11 on, the below, make two L type travelling carriages 20,30 sliding the place aheads that are assembled in C type slide track seat 10 of putting, to be assembled into a slide rail, see also Fig. 2, Fig. 3, the L type travelling carriage 20 of described slide rail, 30 can distinguish the left side that locks up, right board 41,42, when user's pull left side table 41 and L type travelling carriage 20, the gear 11 that described L type travelling carriage 20 can utilize tooth bar 21 to drive C type slide track seat 10 rotates, make another tooth bar 31 of gear 11 transmissions do displacement in the other direction, described tooth bar 31 promptly drives L type travelling carriage 30 and does displacement in the other direction synchronously with right board 42, two L type travelling carriages 20,30 also can utilize each roller 22,32 along the roller guide groove 12 of C type slide track seat 10 and steadily displacement, make two L type travelling carriages 20,30 can drive a left side smoothly, right board 41,42 to outer displacement, and on a left side, right board 41,42 amplification one spaces, and, reach the purpose of finishing amplification desktop usable floor area for inserting a cover plate 43; But, though this a pair of laminar slide rail can utilize two L type travelling carriages 20,30 tooth bar 21,31 with the transmission that cooperatively interacts of the gear 11 of C type slide track seat 10, and make a left side, right board 41,42 outer synchronously moving with the amplification desktop, but described L type travelling carriage 20,30 for steadily slippage on C type slide track seat 10, but be installed with a plurality of rollers 22 overleaf, 32, and on C type slide track seat 10, offer roller guide groove 12, for the sliding roller 22 of putting, 32, so that L type travelling carriage 20,30 not only need set firmly tooth bar 21,31, must loaded down with trivial detailsly set firmly a plurality of rollers 22 one by one more, 32, cause the quite time-consuming inconvenience of assembling operation and reduce production capacity, and each L type travelling carriage 20, a plurality of rollers 22 of 30 configurations, 32 also quite increase the element cost.
Therefore, how to design a kind of except that have can the benefit of two moving amplification desktop usable floor areas, more can be easy to assembling, and effective cost-effective two-layer equation slide rail, be the target of dealer's design.
Summary of the invention
One of the purpose of this utility model provides a kind of two-layer equation slide rail that can two moving pulls extends desktops, be to be provided with first and second the sub-rail that to do displacement in the other direction synchronously in the place ahead of a female rail, it mainly is that upper and lower one bending forming at female rail has the fit slide rail, at the corresponding female rail fit runner position one bending forming of the upper and lower of first and second sub-rail the fit flange is arranged in addition, make first and second sub-rail can utilize first and second fit flange steadily in the fit chute slippage start of female rail, needn't set up a plurality of rollers in addition, reach cost-effective Practical Benefit.
Two of the purpose of this utility model provides a kind of two-layer equation slide rail that can two moving pulls extends desktops, include female rail and first and second sub-rail, it is fit chute and first and second fit flange that cooperatively interacts to be arranged direct one bending forming on female rail and first and second sub-rail, needn't a plurality of rollers of other loaded down with trivial details assembling, reach and be easy to assemble and improve the Practical Benefit of production capacity.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of two-layer equation slide rail that can two moving pulls extends desktops, include female rail and first and second sub-rail, the place ahead of described female rail is sliding first and second sub-rail that is equipped with start in the other direction, it is characterized in that: the upper and lower of described female rail and first and second sub-rail is that the one bending forming has fit chute and first and second fit flange that cooperatively interacts respectively, and first and second sub-rail is by the fit chute slide displacement of first and second fit flange along female rail.
Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be: fit chute and fit flange that can directly bending forming cooperatively interacts on female rail and first and second sub-rail, needn't set firmly roller in addition, reach and save cost and the Practical Benefit that promotes the assembling convenience.
