本发明提出一种用于吊扇的扇叶安装结构100。
请结合参照图1至图4，在本发明一实施例中，该用于吊扇的扇叶安装结构100，包括叶叉底座10、扇叶30以及弹性卡扣组件50。
其中，叶叉底座10设置有至少一个插销11，扇叶30上设有插接孔31以及至少一个安装孔33，插销11卡入所述安装孔33内。弹性卡扣组件50的一部分穿过插接孔31与叶叉底座10固定连接，且弹性卡扣组件50弹性卡持在扇叶30的背离叶叉底座10的一侧表面上。也就是说，弹性卡扣组件50和叶叉底座10固定连接，当扇叶30安装于叶叉底座10时，弹性卡扣组件50部分穿过插接孔31，且弹性卡扣组件50穿过插接孔31的部分弹性卡持于扇叶30背离叶叉底座10的表面。
在实际安装过程中，叶叉底座10的一端与吊扇通过电机驱动的转子进行固定连接，叶叉底座10的另一端与扇叶30进行卡持固定，其中扇叶30的数量一般为3片以上，且3片以上的扇叶30均匀间隔设置。在电机的驱动下，通过转子带动扇叶30以转子为旋转中心进行旋转，以鼓动室内空气以实现室内空气的对流。
可以理解的是，本发明的用于吊扇的扇叶安装结构100可应用于普通吊扇，即具有驱动室内空气流动的吊扇，当然也可应用于灯和吊扇相结合而具有装饰性功能的吊扇灯。其中，扇叶30的材料可以选用金属合金，如此吊扇的风力较强劲；当然，扇叶30还可以选用强度较高的木质复合板，并且可以在扇叶30的表面形成有纹理图案，美观的同时，运行过程中也较安静。叶叉底座10的材料可以是金属材料如铸铁等，通过压铸方式生产制成，叶叉底座10的表面还可以做成旧古铜色，使得吊扇的整体更加美观。
本发明技术方案通过在扇叶30与叶叉底座10之间设置插接配合的插销11和安装孔33的基础上，还在叶叉底座10设置弹性卡扣组件50，并在扇叶30上开设有与弹性卡扣组件50相配合的插接孔31，当扇叶30安装于叶叉底座10时，插销11插入安装孔33的同时，弹性卡扣组件50也部分穿过插接孔31，并弹性卡持于扇叶30背离叶叉底座10的表面，在插销11和安 装孔33以及弹性卡扣组件50和插接孔31的配合下，扇叶30和叶叉底座10紧固连接，并且相对于现有扇叶和叶叉底座的通过多个螺钉或螺栓连接方案，本发明实现了扇叶30和叶叉底座10之间的插接配合，扇叶30和叶叉底座10的组装以及拆卸的方便性得到大大提高。
本实施例中，如图1、图3和图4所示，插销11设置有三个，安装孔33的数量和插销11的数量相匹配，即安装孔33的数量和插销11的数量相等，三个插销11呈等边三角形设置，弹性卡扣组件50位于等边三角形的中心。由此，插销11和弹性卡扣组件50通过上述排布设置，在吊扇使用过程中，扇叶30和叶叉底座10的连接处受力均匀，连接结构牢固。可以理解的是，插销11的数量也可以是3个以上，并且弹性卡扣组件50应位于这多个插销11所构成形状的中心。
请结合参照图2和图3，具体地，弹性卡扣组件50包括导轨51、至少一个卡扣53以及至少一个弹性件55，导轨51与叶叉底座10固定连接，卡扣53与导轨51滑动配合，弹性件55弹性抵持所述卡扣53，卡扣53的一部分穿过插接孔31，并在弹性件55的弹性抵持作用下卡持在扇叶30的背离叶叉底座10的一侧表面上。当扇叶30安装于叶叉底座10时，卡扣53部分穿过插接孔31，在弹性件55的弹性抵持作用下，卡扣53穿过插接孔31的部分卡持于扇叶30背离叶叉底座10的表面。
在扇叶30安装于叶叉底座10时，卡扣53穿过插接孔31的过程中，卡扣53沿导轨51进行线性滑动，并在卡扣53部分穿过插接孔31之后，弹性件55在卡扣53的带动下发生形变而产生弹力作用力反作用于卡扣53，卡扣53则具有沿导轨51返回初始位置(背离插接孔31的圆心方向)的运动趋势，使得卡扣53容置于插接孔31内的部分弹性抵持于插接孔31的孔壁，而卡扣53穿过插接孔31的部分则牢固卡持于扇叶30背离叶叉底座10的表面。本实施例弹性卡扣组件50通过卡扣53、导轨以及弹性件55的组合，卡扣53穿过插接孔31过程中卡扣53产生线性滑动进行避位的过程稳定，扇叶30和叶叉底座10的插接过程更顺畅。
可以理解的是，弹性卡扣组件50的结构还可以是其他形式，如弹性卡扣组件50可以是和叶叉底座10固定连接的至少一个金属钩状件，金属钩状件可以是与叶叉底座10一体成型，也可以是通过焊接方式固定连接叶叉底座10。在扇叶30安装于叶叉底座10的过程中，金属钩状件产生向插接孔31圆心方向弯折的弹性形变，并且钩状部部分穿过插接孔31后，在金属钩状件自身弹性形变的作用下，金属钩状件的钩状部卡持于扇叶30背离叶叉底座10的表面，实现扇叶30和叶叉底座10的固定连接。或者，在其他实施例中，弹性卡扣组件50还可以是两个端部与叶叉底座10铰接而具有一定转动能力的金属钩状件，并且两个金属钩状件之间还设置有扭转弹簧或者压簧，在两金属钩状件件的钩状部穿过插接孔31 之后，在扭转弹簧或压簧的弹力作用下，金属钩状件的钩状部牢固卡持于扇叶30背离叶叉底座10的表面。
在本发明的一些实施例中，卡扣53包括彼此相连的滑动部531和扣合部533，滑动部531和导轨51中的其中一个上形成有滑槽511，滑动部531和导轨51中的另一个设在滑槽511内，扣合部533卡持在扇叶30的背离叶叉底座10的一侧表面上。
请结合参照图2和图3，具体而言，卡扣53包括相连接的滑动部531和扣合部533，导轨51形成有滑槽511，滑动部531容置于滑槽511内，当扇叶30安装于叶叉底座10时，扣合部533卡持于扇叶30背离所述叶叉底座10的表面。本实施例导轨51通过钣金件弯折形成，或者通过压铸一体成型。滑槽511在导轨51的长度方向上两端贯通，卡扣53由滑动部531和扣合部533整体构成L形，并且滑动部531呈倒T形，滑槽511的槽壁形成有与滑动部531的T形台阶相扣合的挡边(未标示)，在卡扣53安装过程中，卡扣53可由导轨51端部的开口滑入滑槽511内，安装过程中较方便，并且在卡扣53安装完成后，通过滑槽511和滑动部531的T形状结构配合，将滑动部531限位于滑槽511内，如此卡扣53不易脱离滑槽511，卡扣53和导轨51的连接结构更稳固。
可以理解的是，在其他实施例中，也可以是滑动部531具有T形的滑槽511，而导轨51具有T形的横截面，如此实现导轨51和卡扣53的牢固连接。
为了实现卡扣53与插接孔31对接过程的顺畅，本实施例在扣合部533的侧面形成为导引斜面5331。如图2和图3所示，扣合部533的侧面沿远离叶叉底座10的方向、朝向靠近插接孔31的中心轴线的方向倾斜延伸。
进一步地，卡扣53为两个，两个卡扣53相对设置，弹性件55位于两个卡扣53之间，且且弹性件55的两端分别弹性止抵在两个卡扣53之间，即弹性件55的两端分别弹性抵接两个卡扣53。更进一步地，每一卡扣53的扣合部533在水平面的投影大致呈半圆形状，两个卡扣53相对设置，在两个卡扣53穿过插接孔31的过程中，由于插接孔31的孔壁对导引斜面5331的挤压使得两个卡扣53沿着导轨51相向靠近滑动，在扣合部533穿过插接孔31之后，在弹性件55的作用下，两卡扣53在背离插接孔31圆心方向上相互远离滑动，并且在卡扣53滑动至插接孔31的边缘时，两卡扣53的扣合部533分别卡持于插接孔31的相对两侧，通过两个卡扣53的卡持作用，扇叶30与叶叉底座10的连接结构较稳固。
当卡扣53设为一个时，弹性件55可一端抵持于卡扣53，另一端抵持于叶叉底座10上的结构，使得卡扣53沿导轨51滑动避位并将扣合部533穿过插接孔31之后，在弹性件55的弹性作用下，卡扣53沿导轨51向背离插接孔31圆心方向滑动，从而卡扣53的扣合部533卡持于扇叶30背离叶叉底座10的表面。
可选地，弹性件55为两个，弹性件55为弹簧，两个卡扣53的彼此相对的表面上分别设有两个安装槽5311，每个安装槽5311的底壁上设有连接柱5313，每个弹性件55的一端设在对应的安装槽5311内并套设在连接柱5313外。如图2和图3所示，弹性件55为弹簧，且弹簧为两个，每一卡扣53的滑动部531凹设有安装槽5311，安装槽5311的底壁凸设有连接柱5313，每一个弹簧的一端容置于安装槽5311内并套设于连接柱5313。本实施例将弹簧套设于连接柱5313，并且弹簧的端部容置于安装槽5311内，在弹簧压缩变形以及弹簧弹性复位过程中，弹簧不易掉落。
请再次结合参照图2和图3，进一步地，叶叉底座10设置有固定框13，导轨51容置于固定框13所成围的空间内。本实施例叶叉底座10于固定框13所围成的槽的槽底壁设置有螺接孔15，导轨51开设有连接孔513，导轨51通过螺钉17与连接孔513和螺接孔15的配合固定连接于叶叉底座10。通过固定框13的设置，当卡扣53在滑槽511内滑动至滑槽511的端口时，固定框13对卡扣53进行限位，并且将导轨51容置于固定框13内，固定框13也对导轨51实现限位固定，在扇叶30安装过程中，导轨51不会因对接过程中有外力的存在产生扭转晃，整个固定结构更牢固。
本实施例固定框13与叶叉底座10为一体成型，整体呈方形结构，可以理解的，于其他实施例中，固定框13可以是两块相对设置的限位板，导轨51的滑槽511两端的开口和正对两限位板设置，如此设置可以进一步节省叶叉底座10的材料降低成本。更进一步的，在其他结构中，也可以将导轨51与叶叉底座10一体成型，而不设置固定框13，导轨51的滑槽511的开口可通过两个与叶叉底座10可拆卸连接的限位板进行限位，防止卡扣53滑动过程中滑出滑槽511。
本发明还提出一种吊扇，该吊扇包括用于吊扇的扇叶安装结构100，该用于吊扇的扇叶安装结构100的具体结构参照上述实施例，由于本吊扇采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
