Abstract
The utility model discloses a kind of rail structure and apply its telescopic ladder made, this rail structure comprises sliding track body, described sliding track body offers chute, the two ends in described track length direction form guide part, the middle part of described chute forms sliding part, and the width of described sliding part is greater than the width of described guide part; By by chute not needing pinpoint middle part widen, well decrease friction and wear unnecessary when tool part moves in chute, tool part is slid freely, enhance the stability that it runs.In addition, also structure is simple, cost of production is low for this rail structure, and especially, this rail structure is not only confined in described telescopic ladder field, and it can be applicable to all need and arranges in the tooling device of slide rail, and application is widely, practical.
Description
Technical field
The utility model relates to ladder technical field, specifically provides a kind of rail structure and applies its telescopic ladder made.
Background technology
Slide rail common on the market, the width of the chute that it is arranged is all wide, but when reality uses, object not easily slides in the chute of said structure, and accordingly, the stability that object runs then is difficult to be guaranteed.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of rail structure and applies its telescopic ladder made, and not only structure is simple for this rail structure, cost of production is low, and also well achieve object slip steady and smooth, stability is high.
The utility model in order to the technical scheme solving its technical problem and adopt is: a kind of rail structure, it coordinates the movement being used for tool part, comprise sliding track body, described sliding track body offers chute, the two ends in described track length direction form guide part, the middle part of described chute forms sliding part, and the width of described sliding part is greater than the width of described guide part.
As further improvement of the utility model, described sliding track body comprises two support frames be arranged side by side, this two support frame is has uncovered rectangular box structure, a side on this two support frame another and along its length also runs through the described chute offering and extend along this side length direction respectively, and this two chute is also in the same plane.
As further improvement of the utility model, described chute is strip through-hole structure.
The utility model additionally provides a kind of telescopic ladder, this telescopic ladder comprises several bench, and rail structure as described above, wherein, each bench includes two armrest parts and the stampeding section being connected this two armrest part, with user to for benchmark, below bench in adjacent two bench can be stretched out and bounce back in the bench of top, the bench being positioned at the top in this some bench another forms the first bench, two armrest parts of described first bench are movable to be respectively inserted in two support frames of described rail structure, and also can slide in this two support frame respectively location stretch out and bounce back.
As further improvement of the utility model, two armrest parts of described first bench are respectively arranged with slide block, this two slide blocks correspondence is slidably mounted in this two chute.
The beneficial effects of the utility model are: this rail structure is not by will chute need pinpoint middle part widen, well decrease friction and wear unnecessary when tool part moves in chute, tool part is slid freely, enhances the stability that it runs.In addition, also structure is simple, cost of production is low for this rail structure, and especially, this rail structure is not only confined in described telescopic ladder field, and it can be applicable to all need and arranges in the tooling device of slide rail, and application is widely, practical.

Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
A kind of rail structure provided by the utility model, it coordinates the movement being used for tool part, it comprises sliding track body 1, described sliding track body offers chute 10, the two ends of described chute 10 length direction form guide part 100, the middle part of described chute 10 forms sliding part 101, and the width of described sliding part 101 is greater than the width of described guide part 100.By chute not needing pinpoint middle part widen, well decrease friction and wear unnecessary when tool part moves in chute, tool part is slid freely, enhance the stability that it runs.
Preferably, described sliding track body comprises two support frames be arranged side by side 11, this two support frame 11 is has uncovered rectangular box structure, a side on this two support frame 11 another and along its length also runs through the described chute 10 offering and extend along this side length direction respectively, and this two chute 10 is also in the same plane.Another preferred, described chute 10 is strip through-hole structure.
Referring to Fig. 3, the embodiment of a kind of telescopic ladder utilizing described rail structure to make of the present utility model is described in detail.This telescopic ladder comprises several bench and rail structure as described above, wherein, each bench includes two armrest parts 2 and the stampeding section 3 being connected this two armrest part, with user to for benchmark, below bench in adjacent two bench can be stretched out and bounce back in the bench of top, the bench being positioned at the top in this some bench another forms the first bench, two armrest parts of described first bench are movable to be respectively inserted in two support frames 11 of described rail structure, and also can slide this two support frame 11 in respectively and locate stretch out and bounce back.
Preferably, two armrest parts of described first bench are respectively arranged with slide block, this two slide blocks correspondence is slidably mounted in this two chute 10.The chute two ends of this rail structure are narrow, middle wide, and namely can not make the first bench sideslip, impact uses; Be beneficial to again opening or packing up of the first bench, it is easily convenient to operate.
In the utility model, this rail structure is not only confined in above-mentioned telescopic ladder field, and it can be applicable to all need and arranges in the tooling device of slide rail, and application is widely, practical.
