下面将参考附图并结合实施例来详细说明本发明。
实施例一
参阅图1和图3,本发明实施例中,一种有利于脊椎的健康成长儿童健康学习椅,包括座板1和底座11,所述座板1的上侧设置有扶手2,座板1的左端设置有支撑架3,所述支撑架3上设置有滑套4,所述滑套4通过第一紧固螺栓5与支撑架6固定,滑套4上连接有靠背6,座板1的右端设置有支撑柱7,所述支撑柱7上设置有升降杆8,升降杆8与支撑杆7通过第二紧固螺栓9连接,升降杆8的上端设置有限位板10,可以对人们的身体进行限位,保证坐姿,保护身体的健康。
所述底座11的上侧左右对称的设置有支撑板13,支撑板13的上部转动连接有转轴14,转轴14的左端设置有调节轮15,转轴14上设置有左螺纹部16和右螺纹部17,左螺纹部16和右螺纹部17上螺纹连接有调节座18,调节座18上侧均设置有第一连接座20,第一连接座20上铰链有调节杆19,调节杆19的上端通过第一连接座20与座板1连接,所述左螺纹部16和右螺纹部17的螺纹旋向相反。本装置的结构设置,需要调节椅子的高度时,通过调节轮15带动转轴14旋转,转轴14上的调节座18就会相向运动或者反向运动,调节方便,通过螺纹调节,调节精度高,并且稳定性好,安全性高,不会出现滑动的情况。
调节杆19的中部设置有防护机构30,防护机构930的另一端与座板1连接,所述防护机构30包括第一伸缩杆25,第一伸缩杆25的两端设置有限位座26,第一伸缩杆25的外侧设置有减震弹簧27,限位座26的外侧设置有连接块28,连接块28上铰链有第二连接座29,两个第二连接座29分别与调节杆19和座板1连接。该装置的结构设置,在使用时,防护机构30可以给调节座18提供一个反向力,中和调节座18在受到压力时,对转轴14施加的横向力,对转轴14进行保护,延长装置的使用寿命。
实施例二
参阅图2,在实施例一的基础上,所述底座11的下侧四角设置有行走机构12,所述底座11的下侧开设有空腔21,行走机构12包括与空腔21连接有第二伸缩杆22,所述第二伸缩杆22的外侧设置有回位弹簧23,第二伸缩杆22的下端设置有滑板,滑板的下侧设置有万向轮24。该结构的设置,在人们坐在椅子上时,万向轮24由于重力的作用,缩进空腔21内,使得椅子不能移动,将椅子位置固定,便于人们保持坐姿,人们起来后,万向轮24就会在回位弹簧23的作用下伸出空腔21,实用性强。
以上所述仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
