Abstract

The utility model relates to a slide rail assembly which comprises an outer slide rail, a middle slide rail and an inner slide rail, wherein one side of the outer slide rail is fixedly arranged in a body with an opening, the middle slide rail is arranged in reciprocating slide in the outer slide rail, and the inner slide rail is arranged in reciprocating slide in the middle slide rail, one side of the inner slide rail is used for connecting an object so that the object internally enters and exits the body outside the opening. The slide rail assembly can extend and withdraw within a range from a minimum length to a maximum length, and the inner end of the inner slide rail protrudes from the inner end of the outer slide rail when the inner slide rail interlocks the middle slide rail and pushes the outer slide rail on a maximum travel so that the outer ends of the inner slide rail and the middle slide rail enter the interior of the outer slide rail. The utility model can greatly decrease the cost of length materials on the premise that the functions are not influenced.

Description

Slide rail set

Technical field

The utility model is relevant with rail structure, is meant the Tool Cabinet that generally is provided with several drawers or the structure of sliding rail assembly of file cabinet especially.

Background technology

Pressing, commonly use the push-pull configuration between drawer and casing, is to be provided with corresponding two tracks between the two, makes drawer be arranged at box house and does push pull maneuver by chimeric each other.

See also Figure 1A and Figure 1B, further person, one drawer 91 design usually has long depth, to increase the capacity that to take in article, and for make drawer 91 need not de-orbit can be fully or major part pull out a casing 92 outsides, further be provided with three tracks as a casing slide rail 93, one middle slide rail 94, a drawer sliding rail 95, each slide rail forms a slide rail set 9, slip after making up mutually by each slide rail, to drawer 91 need not be de-orbited and bigger displacement can be arranged pulling out casing 92 outsides fully, and can make drawer 91 unlikely disengaging casings 92 and drop; Wherein, be provided with a ball bearing 96,97 between aforementioned each slide rail,, make each slide rail be easy to each other slide and reduce noise to reduce frictional force between each slide rail.

Generally speaking, the length of this casing slide rail 93, middle slide rail 94 and drawer sliding rail 95 about equally, wherein, the length of this centre slide rail 94 is slightly smaller than the length of casing slide rail 93 and drawer sliding rail 95, when fully pushing casing slide rail 93 at the middle slide rail 94 of drawer sliding rail 95 interlocks, this drawer sliding rail 95 and middle slide rail 94 are to be incorporated in casing slide rail 93 inside, and with regard to the basis of length material, each slide rail all has approximately identical length material; In addition, this drawer 91 and casing 92 are the slide rail set that can obtain and be suitable for the manufacturing of different manufacturers, basically, as long as cording had identical length when these slide rail set fully pushed casing slide rail 93 at the middle slide rail 94 of drawer sliding rail 95 interlocks, in other words, the minimum length of these slide rail set is identical.

Summary of the invention

The specific embodiment

See also Fig. 2 A and Fig. 2 B, first embodiment of the utility model slide rail set 1, it includes slide rail 16 in an external slide rail 12, one middle slide rail 14 and.

This external slide rail 12 tools one suitable length, at long axis direction with before and after the one side and be located at a body 11 (as casing) with opening 111 regularly.

This centre slide rail 14 cordings, one suitable length and in long axis direction can be located at this external slide rail 12 slidingly back and forth.

Should in slide rail 16 cordings, one suitable length and in long axis direction can be located at this centre slide rail 14 slidingly back and forth, slide rail 16 1 sides are in order to connect an object 13 (as drawer) in this, make in this object 13 is outside this opening 111 this body 11 of coming in and going out.

This slide rail set is scalable and has a maximum length (outer, middle, interior slide rail draws back mutually to maximum) and a minimum length (outer, middle, interior slide rail is slippaged mutually together to minimum).

Wherein, push to this centre slide rail 14 of slide rail 16 interlocks in this and range this external slide rail 12, make should in slide rail 16 outer ends and this centre slide rail 14 outer ends enter this external slide rail 12 when inner, in this slide rail 16 inner be to protrude in this external slide rail 12 the inners.

The utility model is for the slide rail set of commonly using, first embodiment of the present utility model is the length that shortens this external slide rail 12 and this centre slide rail 14, when pushing this external slide rail 12 to this centre slide rail 14 of slide rail 16 interlocks in this and range, keep this centre slide rail 14 and be incorporated in this external slide rail 12 inside, should interior slide rail 16 parts be to be incorporated in this external slide rail 12 inside, should interior slide rail 16 another part be to protrude in this external slide rail 12 the inners, the minimum length of the utility model slide rail set still is equal to the corresponding minimum length of commonly using slide rail set, therefore, the utility model still obtains as commonly using the Telescopic of slide rail set, of the present utility model should in slide rail 16 also have as commonly using the loading capacity of slide rail set just like a cantilever beam, but the utility model has reduced material cost.

Aforementioned first embodiment of the present utility model (Fig. 2 A and Fig. 2 B), wherein, when slide rail 14 in the middle of interior slide rail 16 interlocks and range ground push external slide rail 12 (Fig. 2 B), the distance that interior slide rail 16 the inners protrude in external slide rail 12 the inners is greater than 1/10th of the minimum length of the utility model slide rail set.

Further the person is provided with a ball bearing at this external slide rail 12, this centre slide rail 14 and in being somebody's turn to do between the slide rail 16, and in order to reduce respectively frictional force between this slide rail, making respectively, this slide rail is easy to slide and reduce noise each other.

See also Fig. 3 A and Fig. 3 B, it is second embodiment of the present utility model, second embodiment system is developed by first embodiment, second this external slide rail 12 length system that implements is shorter than first these external slide rail 12 length of implementing, in other words, push to slide rail 14 in the middle of interior slide rail 16 interlocks and range external slide rail 12, when slide rail 16 outer ends and middle slide rail 14 outer ends enter external slide rail 12 inside in making (Fig. 3 B), middle slide rail 14 the inners are to protrude in external slide rail 12 the inners, slide rail 14 the inners in the middle of interior slide rail 16 inner systems protrude in, and the distance system that slide rail 16 the inners protrude in external slide rail 12 the inners in not needing is greater than 1/10th of the minimum length of the utility model slide rail set.

The utility model is taken off second embodiment, and wherein, interior slide rail 16 length are greater than middle slide rail 14 length, and middle slide rail 14 length are greater than external slide rail 12 length.

See also Fig. 4 A and Fig. 4 B, it is the 3rd embodiment of the present utility model, the 3rd embodiment is that certificate is by second embodiment, make interior slide rail 16 length of being somebody's turn to do of the 3rd enforcement system be shorter than interior slide rail 16 length of being somebody's turn to do of second enforcement, in other words, outside the interior slide rail 16 of second embodiment, bring in the length of slide rail 16 in shortening, then more reduce material cost.

More than notion of the present utility model be in external slide rail 12 and middle slide rail 14, to bring in and shorten its length but the length of slide rail 16 in keeping, and then shorten again this external slide rail 12 length and and then more again in this outer bringing in of slide rail 16 shorten its length to reduce material cost.
