Description

A kind of automatic posture-correcting chair

Technical field

The utility model belongs to student with height adjustable seating technical field, and in particular to a kind of automatic posture-correcting chair.

Background technology

Student is the flower of motherland, even more a national hope；The desk and chair of student is that a student learns daily Too busy to get away apparatus, especially primary school period to senior high school period chair and desk for pupils, due to this stage student's growth and development compared with Soon, all there is the unmatched situation of height of the height and student of tables and chairs in many schools in the whole nation；Although annual country's input is a large amount of Fund for update to chair and desk for pupils；Important is the manufacturing firms of tables and chairs the most does not just account for when designing tables and chairs The problem of whether being matched to the height of tables and chairs with the height of student.

The height of tables and chairs and student mismatch can cause many problems, be easy to keep student's vertebra excessively preceding bent or even camel first The back of the body, bends body for a long time, can also influence lung's development, the ventilatory of lung and cardio-pulmonary function, leads to that thorax is small, lung capacity It is small, it is easy fatigue, disease-fighting capabilities decrease etc.；In addition from the perspective of skeletology, long-term, the consistent row of duration To may result in the deformation of bone, such as the people's shoulder for often shouldering thing can tilt, the human hand influential point of bone deformity write, then The shape of the improper face vertebra of long-term sitting posture also has undesirable influence；Secondly student's height and desk and chair height mismatch, The distance between eyes and books can be influenced, so as to cause myopia；The bad shadow of sitting posture again rings attention, the memory of student, Student can be made to feel fatigue and generate mood of being weary of studying.

The preferable school of some economic conditions at present, is equipped with for students, the chair that can highly adjust, these height The chair that can be adjusted is usually used, and the mode of bolt adjusting or hydraulically extensible carries out the height adjusting function of chair, The problem of being primarily present be：It is more complicated when 1, realizing that height is adjusted, and than relatively hazardous, hold during tightening bolt Easily injure the hand of student；2, the gear for adjusting height is less, does not adapt to the student of different heights, the demand to chair height； Inventor has developed a kind of automatic posture-correcting chair based on defect in the prior art.Existing in the prior art ask can be solved very well Topic.

Utility model content

In order to solve the above-mentioned technical problem the utility model, provides a kind of automatic posture-correcting chair, structure design is simple, science Rationally, more complicated when can solve height adjusting in the prior art, and than relatively hazardous, hold during tightening bolt The problem of easily injuring the hand of student, while the gear for also solving adjusting height is less, does not adapt to the student of different heights, it is right The problem of demand of chair height.

Technical solution used by the utility model is：A kind of automatic posture-correcting chair, including backrest, seat surface, pedestal, folding dress It sets, carriage, driving device；Backrest is fixed at the posterior edges position of seat surface, and the edge of backrest is provided with backrest branch Column, back bar are fixedly installed around three sides of backrest；Folding device is fixed at the junction of backrest and seat surface；Pedestal It is fixed at the lower part of seat surface, sliding panel is cross-shaped, is fixedly connected by two between pedestal and seat surface, two intersections The hinged place of sliding panel be provided with articulated shaft；Pedestal includes cross-brace body, and cross-brace body is provided with two, flat in left and right Row setting, longitudinal bracing body is provided with two, is arranged in parallel in front and back, two longitudinal bracing bodies two cross-brace bodies it Between, respectively with cross-brace body vertical connection, battery pack is fixed on two longitudinal bracing bodies；Folding device includes axis It holds, bearing is fixed at the centre position of two vertical back bars, before bearing passes through vertical back bar by pivot pin Afterwards, bearing is fixed, support connecting plate is being arranged in the both sides of two vertical back rest supports columns, and there are four fixed pillar settings, Close to the position of folding device, other two is fixed at vertical back bar for two front and rear sides for being fixed at seat surface Front and rear sides position, support connecting plate be fixedly connected on fixation pillar and vertical back bar on seat surface fixation pillar it Between, it supports on connecting plate equidistantly, is evenly arranged with adjustment hole；Carriage and driving device are fixed at cross-brace body Inside；Switch is fixed at the forward position of seat surface.
