Description
Technical field
The utility model relates to the adjustable chair of a kind of telescopic.
Background technology
Chair is indispensable article during we live, in the city that population is more and more intensive, for public place or the less family of part floor space, often there is the situation that chair uses not, but arrange that more chair not only can take too many spatial area, and affect attractive in appearance.Waste the problem of taking up an area space when not using in order to solve existing chair, solution mostly is employing faldstool, and this kind of joint-stool is folded up comparatively hard, and after folding, almost use is little, when again needing to use, restores to the original state again difficultly.
Utility model content
Technical problem to be solved in the utility model is the defect existed for prior art, provides the chair that a kind of telescopic is adjustable, solves existing chair and takes up an area large, the folding rear disabled problem in space.
The utility model solves the problems of the technologies described above taked technical scheme: the chair that a kind of telescopic is adjustable, comprises chair frame, chair body plate, telescoping mechanism and scissor structure;
The bottom of described chair frame is as the support of chair and horizontal plane, and the top of chair frame is as the support of chair body plate;
The described bottom of chair body plate and the edge of back-rest are provided with guide rail, and the fork at scissor structure two ends is arranged in guide rail, thus are coupled together by adjacent chair body plate, and Far Left is fixedly connected with chair frame with rightmost chair body plate;
Described telescoping mechanism comprises extension sleeve and expansion link, and extension sleeve is fixedly mounted on the bottom of chair frame and the back of back-rest; Expansion link one end is fixedly connected with chair frame, and the flexible position of the other end is socketed in extension sleeve; When chair needs to extend, both sides chair frame promoted outward, the fork of scissor structure slides in guide rail, and the flexible position of simultaneous retractable bar is stretched out in extension sleeve, realizes chair length.
Further, described chair frame comprises left chair frame, middle chair frame and right chair frame, and extension sleeve is fixedly mounted in middle chair frame, and expansion link comprises left expansion link and right expansion link, left expansion link is fixedly connected with right chair frame with left chair frame respectively with one end of right expansion link, and the other end is socketed in extension sleeve.
Elongation and the compression of the utility model by adopting scissor structure and telescoping mechanism to realize chair, when chair needs to extend, both sides chair frame is promoted outward, the fork of scissor structure slides in guide rail, the spacing of the fork of scissor structure both sides reduces, the flexible position of simultaneous retractable bar is stretched out in extension sleeve, realizes chair length; When chair does not have so much people to use, both sides chair frame promoted in opposite directions, the fork of scissor structure slides in guide rail, the spacing of the fork of scissor structure both sides strengthens, the flexible position of simultaneous retractable bar is got back in extension sleeve, and chair recovers compression shape, still can sit.The utility model structure is simple, easy to use, has good use value and dissemination.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described further.
As Figure 1-Figure 4, the chair that a kind of telescopic is adjustable, comprises chair frame 1, chair body plate 2, telescoping mechanism 4 and scissor structure 3;
Described chair frame 1 comprises left chair frame 101, middle chair frame 102 and right chair frame 103, and the bottom of chair frame 1 is as the support of chair and horizontal plane, and the top of chair frame 1 is as the support of chair body plate 2;
The described bottom of chair body plate 2 and the edge of back-rest are provided with guide rail, the fork at scissor structure 3 two ends is arranged in guide rail, thus adjacent chair body plate 2 is coupled together, Far Left is fixedly connected with right chair frame 103 respectively at left chair frame 101 with rightmost chair body plate 2;
Described telescoping mechanism 4 comprises extension sleeve 402 and expansion link 401, and extension sleeve 402 is fixedly mounted on the bottom of middle chair frame 102 and the back of back-rest; Expansion link 401 comprises left expansion link and right expansion link, and left expansion link is fixedly connected with right chair frame 103 with left chair frame 101 respectively with one end of right expansion link, and the other end is socketed in extension sleeve 402.
Flexible principle of the present utility model is as follows:
When extending chair, chair frame 1 promoted outward, the fork of scissor structure 3 slides in guide rail, and the spacing of the fork of scissor structure 3 both sides reduces, and the flexible position of simultaneous retractable bar 401 is stretched out in extension sleeve 402, realizes chair length; During compression chair, both sides chair frame 1 promoted in opposite directions, the fork of scissor structure 3 slides in guide rail, and the spacing of the fork of scissor structure 3 both sides strengthens, and the flexible position of simultaneous retractable bar 401 is got back in extension sleeve 402, and chair then recovers to compress shape.
