The utility model object realizes with the following methods: a kind of structure-improved of three joint drawer guideways, it comprises the outer rail distributed successively from outside to inside, middle rail and interior rail, be provided with by some needle rollers of locating rack supporting and location between middle rail and interior rail, reset buffer is installed in outer rail, it is characterized in that: described middle rail is integrally bent into the first side plate by sheet material, top board, second side plate, and base plate, above-mentioned four form not closed " mouth " shape cross section, and the turning point between the second described side plate and top board is provided with the guide groove of inside arc depression;
Described outer rail is bent into the first outer panel by sheet material equally, first roof sheet and the second outer panel form opening channel-shaped cross section, first and second outer panel above-mentioned is provided with the first bearing plate and the second bearing plate to direction bending in groove, the first guide portion is formed between the second described bearing plate and guide groove, first ball is installed in this groove, form the second gathering sill between the first described side plate and the second outer panel of outer rail, the second ball is installed in above-mentioned gathering sill.
First side plate of described middle rail is also installed with some other wheels, other wheel is pressed on the second bearing plate of outer rail.
Described other wheel is the metal bearing be fixed on by rivet on middle rail.
Described other wheel is one, is arranged on the medium position of middle rail.
Described other wheel is two, and head and the tail are distributed on middle rail.
Described other wheel is three, be distributed in the head of middle rail, in, afterbody.
Described guide groove diameter is more than or equal to the first ball diameter.
The first described ball and the second ball are arranged on pearl nest frame, and pearl nest frame top is provided with some needle rollers Free-rolling between outer rail and interior rail.
The beneficial effects of the utility model are: 1) utilize structure more simple, and the other wheel that production cost is lower replaces rail structure in traditional double inner groovy, has structure reliably firm, yield rate advantages of higher.2) in, rail structure is easy to process, and technique is simple, and production efficiency is high, is conducive to improving the market competitiveness.

Detailed description of the invention
Below in conjunction with accompanying drawing, concrete further instruction is done to the utility model.A kind of structure-improved of three joint drawer guideways, it comprises the outer rail 1, middle rail 2 and the interior rail 3 that distribute successively from outside to inside, be provided with between middle rail 2 and interior rail 3 by some needle rollers 41 of locating rack 4 supporting and location, reset buffer 5 is installed in outer rail 1, it is characterized in that: described middle rail 2 is integrally bent into the first side plate 21 by sheet material, top board 22, second side plate 23, and base plate 24, above-mentioned four form not closed " mouth " shape cross section, and the turning point between the second described side plate 23 and top board 22 is provided with the guide groove 25 of inside arc depression;
Described outer rail 1 is bent into the first outer panel 11 by sheet material equally, first roof sheet 12 and the second outer panel 13 form opening channel-shaped cross section, first and second outer panel 11,13 above-mentioned is provided with the first bearing plate 14 and the second bearing plate 15 to direction bending in groove, the first guide portion is formed between the second described bearing plate 15 and guide groove 25, first ball 6 is installed in this groove, form the second gathering sill between the first described side plate 21 and the second outer panel 13 of outer rail, the second ball 61 is installed in above-mentioned gathering sill.
First side plate 21 of described middle rail 2 is also installed with some other wheels 7, other wheel is pressed on the second bearing plate 15 of outer rail 1.
Described other wheel 7 is the metal bearing be fixed on by rivet 71 on middle rail.
Described other wheel 7 is one, is arranged on the medium position of middle rail.
Described other wheel 7 is two, and head and the tail are distributed on middle rail.
Described other wheel 7 is three, be distributed in the head of middle rail, in, afterbody.
Described guide groove 25 diameter is more than or equal to the first ball diameter.
The first described ball and the second ball are arranged on pearl nest frame, and pearl nest frame top is provided with some needle rollers 41 Free-rolling between outer rail 1 and interior rail 3.
Operation principle: in the utility model, complicated for solving rail structure processing technology in traditional double indent, production cost is high, the drawback under yield rate, and the middle rail structure of this single concave has been invented in design.The second side plate 23 in this in rail and the turning point between top board 22 are provided with the guide groove 25 of inside arc depression, first ball is installed in this guide groove, ball is by this guide groove, second bearing plate 15 and outer rail second outside in the guide portion that formed between 13, spacing this ball that can make from three directions is free to slide between middle rail and outer rail, plays the effect of sliding support.At the opposite side of middle rail, the guide groove caved inward then is not set, and use flat design instead, at its sidewall, other wheel is installed, and in this place, the second ball is installed between rail and outer rail, ball ensures the slip of sidewall between interior rail and middle rail, other wheel is then free to slide on the first bearing plate 14 of outer rail, realizes the location, three directions of external, middle rail, meets the motion needs of slide rail.Wherein for ensureing service life and the economic benefit of other wheel, generally arranging 1 to 3 metal bearing is advisable, if only arrange 1, is arranged on the medium position of middle rail, mainly bears downward pressure, realizes the normal operation of slide rail.
