第一实施例
请参阅图1，本实施例提供了一种旋转结构100，本实施例提供的旋转结构100能够保证椅背可相对于车座旋转360度的同时避免连接线200被绞断，从而提高了安全座椅10的使用寿命。
本实施例提供的旋转结构100主要应用于安全座椅10上，安全座椅10 主要安装在车上，小朋友坐车时，安全座椅10可以将小朋友固定在车上，提高小朋友坐车时的安全性能。
请参阅图1及图2，在本实施例中，旋转结构100包括安装座110、旋转件120及限位件130，旋转件120与安装座110转动连接，限位件130安装在安装座110上，限位件130选择性地与旋转件120抵持，以限制旋转件120相对于安装座110的转动。
在本实施例中，通常情况下，安装座110安装在车座上，安全座椅10的椅背安装在旋转件120上，当小朋友坐在安全座椅10的椅背上时，可以通过旋转件120相对于安装座110转动从而调节椅背与车座的角度。
在本实施例中，安装座110与椅背之间采用连接线200连接，当旋转件120相对于安装座110转动时，限位件130可以限制旋转件120相对于安装座110的旋转角度，避免旋转件120相对于安装座110连续旋转多圈，导致连接线200被绞断。本实施例提供的旋转结构100能够保证椅背可相对于车座旋转360度的同时避免连接线200被绞断，从而提高了安全座椅10的使用寿命。
请参阅图2及图3，在本实施例中，安装座110上设置有连接槽112，限位件130包括相互连接的连接段132及抵持段134，连接段132安装在连接槽112内，抵持段134选择性地与旋转件120抵持。
在本实施例中，限位件130的连接段132安装在连接槽112里面，将连接段132安装在连接槽112里能够提高限位件130与安装座110之间的固定效果，避免限位件130轻易从安装座110上脱落下来。
请参阅图4，其中，旋转件120上设置有连接件122，连接件122选择性地与抵持段134抵持，以限制旋转件120的转动。
请参阅图5及图6，在本实施例中，旋转件120与安装座110之间转动连接，旋转件120可以相对于安装座110顺时针方向转动或者逆时针方向转动。其中，顺时针方向与逆时针方向均以从安装座110的方向朝向旋转件120的方向上为准。
当旋转件120相对于安装座110顺时针转动，连接件122转动至抵持段134处时，连接件122与抵持段134相互抵持，旋转件120在顺时针方向上相对于安装座110停止转动。
同样，当旋转件120相对于安装座110逆时针转动，连接件122在逆时针方向上转动至抵持段134处时，连接件122与抵持段134相互抵持，旋转件120在逆时针方向上相对于安装座110停止转动。
在本实施例中，旋转件120可以在顺时针方向上及逆时针方向上均旋转一周，使椅背可以相对于车座调节至任意角度。
在本实施例中，连接段132与连接槽112滑动连接，连接段132可在连接槽112的延伸方向上滑动。当连接件122转动至抵持段134上，并与抵持段134相互接触时，旋转件120相对于安装座110继续转动，并带动限位件130在连接槽112内滑动，当限位件130在连接槽112内滑动到位后，连接段132与连接槽112的内壁抵持，抵持段134与连接件122相互抵持，从而限制旋转件120相对于安装座110的转动角度。
请参阅图2，在本实施例中，连接槽112具有止挡面114，在旋转件120抵持限位件130在连接槽112内滑动至止挡面114时，止挡面114与连接段132相互抵持，以限制旋转件120的转动。
在本实施例中，连接槽112的延伸方向与旋转件120的转动方向一致，止挡面114设置在连接槽112的延伸方向上。可以理解为止挡面114为连接槽112的延伸方向上的端面，当限位件130在连接件122的带动下运动至止挡面114处时，连接段132与止挡面114抵持，使旋转件120相对于安装座110停止，采用该种方式，当连接件122接触到限位件130后，限位件130在连接槽112内滑行一段距离，可以对旋转件120起到缓冲作用，避免限位件130与连接件122之间刚性直接碰撞，影响二者的使用寿命。
在本实施例中，止挡面114为两个，两个止挡面114分别在设置在连接槽112的延伸方向上的两端。
在本实施例中，两个止挡面114分别为连接槽112在其延伸方向上的两个端面，当旋转件120相对于安装座110顺时针方向旋转时，连接段132 与两个止挡面114中位于右边的止挡面114相互抵持。当旋转件120相对于安装座110逆时针方向旋转时，连接段132与两个止挡面114中位于左边的止挡面114相互抵持。
在本实施例中，连接槽112呈弧形。弧形的连接槽112与旋转件120的旋转方向对应，能够保证连接件122与抵持段134相互抵持。
需要说明的是，在本实施例中，连接槽112为弧形，但是不限于此，在本实用新型的其他实施例中，连接槽112还可以呈矩形等其他形状，与本实施例等同的方案，能够达到本实施例的效果的，均在本实用新型的保护范围内。
在本实施例中，安装座110上设置有导向槽116，连接槽112设置在导向槽116的底壁上，旋转件120上设置有连接件122，连接槽112设置在导向槽116内，并与限位件130选择性地配合。
在本实施例中，导向槽116呈环形，连接件122设置在导向槽116内，当旋转件120相对于安装座110转动时，连接件122在导向槽116的延伸方向上滑动。当连接件122在导向槽116内滑动至限位件130处时，与抵持段134相互接触，并带动连接段132在连接槽112内滑动，当滑动至止挡面114处时，连接段132与止挡面114抵持，使连接段132与连接件122相互抵持，从而使旋转件120停止转动，能够避免旋转件120相对于安装座110转动多圈，将连接线200绞断。
在本实施例中，连接槽112的延伸方向与导向槽116的延伸方向相同。
综上所述，本实施例提供的旋转结构100，在本实施例中，安装座110与椅背之间采用连接线200连接，当旋转件120相对于安装座110转动时，限位件130可以限制旋转件120相对于安装座110的旋转角度，避免旋转件120相对于安装座110连续旋转多圈，导致连接线200被绞断。本实施例提供的旋转结构100能够保证椅背可相对于车座旋转360度的同时避免连接线200被绞断，从而提高了安全座椅10的使用寿命。
第二实施例
本实施例提供了一种安全座椅10，本实施例提供的安全座椅10能够保证可相对于车座旋转360度的同时避免连接线200被绞断，从而提高了安全座椅10的使用寿命。
为了简要描述，本实施例未提及之处，可参照第一实施例。
在本实施例中，安全座椅10包括连接线200、椅背及第一实施例提供的旋转结构100，连接线200电连接安装座110及椅背，椅背安装在旋转件120上。
在本实施例中，旋转件120上设置有安装孔，连接线200穿过安装孔与椅背电连接。
以上所述仅为本实用新型的优选实施例而已，并不用于限制本实用新型，对于本领域的技术人员来说，本实用新型可以有各种更改和变化。凡在本实用新型的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本实用新型的保护范围之内。
