具体实施方式
下面结合各附图，对本实用新型做详细描述。
请参考图1-8所示，本实用新型提供一种悬臂伞，包括：立柱1、伞篷4和悬臂3，悬臂3一端通过壳体2可转动地连接立柱1，另一端连接伞篷4，通过转动悬臂3带动伞篷4转动使得伞篷4开口相对水平方向转动一个角度。
所述悬臂伞还包括限位件5，限位件5一端与悬臂3固定连接，另一端伸入所述壳体2内，所述壳体2内壁设有第一限位部201，所述限位件5上设有第二限位部51，所述第一限位部201与所述第二限位部51相配合限制悬臂在其周向方向的转动范围。
本实用新型中，转动悬臂3使得伞篷4开口发生转动时，限位件5随着转动，并带着第二限位部51转动，通过第一限位部201对第二限位部51的限制从而限制悬臂3的转动范围，从而实现了对伞篷4开口朝向的转动限位。本实用新型通过设置限位件5可以避免使用者将伞篷4转向至仰角过大的位置，从而避免在受到较大外力(风力)情况下发生倾翻的问题。
进一步地，所述壳体2包括滑块壳体21和悬臂壳体22，所述滑块壳体21可滑动地设于立柱1上，所述悬臂壳体22可枢转地安装于滑块壳体21一端，所述第一限位部201设于所述悬臂壳体22上，第二限位件5安装于所述悬臂壳体22内。这样的结构设置使得悬臂3可以相对立柱1收拢在一起，便于收纳；还可以使得悬臂3相对立柱1张开一定夹角，从而给伞篷4提供较好的支撑结构，便于展开伞篷4。
一实施例中，请参考图2-8所示，所述第一限位部201为沿悬臂壳体22内壁周向设置的限位凹槽，所述第二限位部51的端部插入所述限位凹 槽中，所述第二限位部51的移动范围被限制在限位凹槽的两端之间。
另一实施例中，请参考图9-11所示，所述第一限位部201为沿悬臂壳体22内壁周向设置的至少两个限位凸台，至少两个限位凸台之间形成限位空间200，所述第二限位部51的端部插入所述限位空间200中，所述第二限位部51的移动范围被限制在两个相邻的限位凸台之间。
一实施例中，请参考图7、8所示，所述第二限位部51为穿设于所述限位件5上的限位插销。本实施例中，限位插销插入限位凹槽中，使得限位插销只能在限位凹槽内移动。
另一实施例中，请参考图9-11所示，所述第二限位部51为形成于所述限位件5表面的限位凸起。如图10所示，限位凸起靠于限位凸台一侧，此时，悬臂不能继续顺时针转动，只能反向转动，直到限位凸起被另一侧的限位凸台挡住。
进一步地，悬臂伞还包括限位显示件6，所述限位显示件6固定于悬臂3的一端。图7所示实施例中，所述限位插销51穿过所述限位显示件6从而将限位显示件6固定于悬臂3上。所述限位显示件6一端伸入悬臂壳体22内，另一端从悬臂壳体22中露出，所述限位显示件6露出悬臂壳体22的一端设有第一限位显示块61，所述悬臂壳体22的端部设有两个间隔设置的第二限位显示块62，所述第一限位显示块61位于两个第二限位显示块62之间，第一限位显示块61在两个第二限位显示块62之间可活动的范围与第二限位部51在悬臂壳体22内可活动的范围一致，也就是，第一限位显示块61在两个第二限位显示块62之间可活动的范围与限位插销在限位凹槽中可活动的范围一致。
转动悬臂3时，第二限位部51在悬臂壳体22内移动(即限位插销在限位凹槽中移动)，同时第一限位显示块61在两个第二限位显示块62之间移动，通过第一限位显示块61的移动位置提示第二限位部51在悬臂壳体22内移动的位置(即限位插销在限位凹槽中移动的位置)。
本实施例中，设有可视的第一限位显示块61和第二限位显示块62，通过第一限位显示块61的移动位置可以判断出限位插销在限位凹槽中的位置，避免了限位插销已经移动到限位凹槽端部后继续移动限位插销(即 转动悬臂3)，可避免用力过大而造成的悬臂壳体22内部结构的破坏。
限位件5、限位显示件6和悬臂3上均设有插销孔510，限位插销从插销孔510中插入即可连接并相对固定限位件5、限位显示件6和悬臂3，安装非常方便。
进一步地，所述限位件5上设有数条凸棱52，可以减轻限位件5的重量，同时节省材料，降低成本。进一步地，限位件5通过铆钉与悬臂3固接，可确保限位件5与悬臂3之间连接牢固。
进一步地，所述悬臂伞还包括斜杆13，斜杆13的一端枢接于立柱1的上端，另一端枢接于悬臂3，从而将悬臂3吊起，起到支撑悬臂3的作用。
伞篷4包括伞骨和篷布，其结构与现有的伞篷结构相同，在此不作赘述。
所述悬臂伞还包括伞篷开合机构和伞篷转向机构。
伞篷开合机构设于滑块壳体21内，用于控制伞篷4的开合。伞篷开合机构包括开合转轮71和张紧绳，开合转轮71可转动地安装于所述滑块壳体21内，张紧绳的一端缠绕于开合转轮71上，另一端穿过悬臂3连接伞篷4，通过转动所述开合转轮71收紧或放松所述张紧绳从而控制伞篷4的开合。开合转轮71具有露出滑块壳体21的一端，从而方便该端连接摇手柄75，通过摇手柄75控制所述开合转轮71转动。
伞篷转向机构设于悬臂壳体22内，用于控制悬臂3的旋转以转动伞篷4的开口的朝向。伞篷转向机构包括蜗杆73和蜗轮74，蜗杆73可转动地安装于悬臂壳体22内，且蜗杆73具有露出悬臂壳体22的一端，该端用于连接摇手柄75，从而摇手柄75控制蜗杆73转动。所述蜗轮74套设于限位件5的外侧，并与限位件5固接，蜗轮74与蜗杆73相啮合，由蜗杆73驱动蜗轮74转动。当蜗杆73连接摇手柄75时，转动摇手柄75，摇手柄75驱动蜗杆73转动，蜗杆73驱动蜗轮74转动，蜗轮74带动限位件5转动，限位件5带动悬臂3转动，从而使得伞篷4的开合朝向发生转动。
所述悬臂伞还包括可拆卸地连接于开合转轮71或蜗杆73的摇手柄 75，将摇手柄75连接于开合转轮71或蜗杆73时，可控制伞开合或控制伞篷4开口的转向。
所述悬臂壳体22的外表面设有指示伞篷4开口朝向的转动方向的指示标识220，所述指示标识220包括指示箭头和/或文字，从而可以提示使用者将伞篷4转至开口朝向需要的方向。
请参考图2所示，所述悬臂伞还包括设于滑块壳体21内的滑块定位机构8，该滑块定位机构8用于将滑块壳体21固定于立柱1的任意位置，使得悬臂3可相对立柱1张开不同大小的夹角，从而可以调整伞篷4的高度。
一实施例中，请参考图12-15所示，所述滑块定位机构8包括定位齿条81、定位块82和把手85。定位齿条81设于立柱1一侧，定位块82沿着靠近或远离定位齿条81的方向可移动地安装于滑块壳体21内。所述定位块82朝向所述定位齿条81的一端设有固定齿821，所述固定齿821与所述定位齿条81面接触咬合以固定所述定位块82。把手85的一端可转动地安装于所述滑块壳体21，把手85的另一端连接所述定位块82以带动所述定位块82移动。所述固定齿821的齿数为两个以上，保证了足够的支撑强度，从而支撑悬臂3，进而使得连接悬臂3的伞篷4保持稳定。
本实施例中，通过转动把手85可以带动定位块82移动，从而定位块82靠近或远离定位齿条81，当定位块82靠近齿条，固定齿821与定位齿条81面接触咬合时，定位块82固定在立柱1上的某一位置，也就使得滑块定位机构8及滑块壳体21固定在立柱1上的某一位置；当定位块82远离齿条时，固定齿821与定位齿条81分开，则滑块壳体21可以沿着立柱1移动，从而调整滑块壳体21的位置。由于固定齿821与定位齿条81之间通过面接触咬合，并且固定齿821的齿数为两个以上，这样的结构受力点分散到定位齿条81中，且保证了足够的支撑强度，可以稳固地安装伞篷4，当伞篷4受风吹时，不容易损坏该结构。
请参考图12所示，所述滑块壳体21可以包括第一滑块壳体211和第二滑块壳体212，第一滑块壳体211和第二滑块壳体212相配合形成壳体结构，进一步地，所述第一滑块壳体211和所述第二滑块壳体212通过螺 丝固定在一起，便于安装。
所述滑块定位机构8还包括弹性复位件83，连接所述滑块壳体21和所述定位块82以使得所述定位块82具有朝所述定位齿条81移动的趋势。初始位置时，如图14所示，固定齿821与定位齿条81相互咬合；此时按压把手85，把手85转动带动固定齿821远离限位齿，则弹性复位件83被压缩，如图15所示，此时可以调整滑块壳体21的位置。松开把手85后，由于弹性复位件83的作用，使得定位块82朝定位齿条81移动，固定齿821再次与定位齿条81咬合，如图14所示，从而固定住滑块壳体21及与之相连的结构。设置弹性复位件83可以实现定位块82的自动复位，松开把手85即可重新固定滑块壳体21，使用上更加方便。
进一步地，所述弹性复位件83为压簧，该压簧的两端分别抵住定位块82和滑块壳体21，并使得定位块82具有靠近定位齿条81移动的趋势，使得固定齿821与定位齿条81之间咬合更牢固。
请参考图13所示，所述定位块82两侧设有导向凸块822，所述滑块壳体21对应所述导向凸块822设有导向槽210，所述导向凸块822插入所述导向槽210内与所述导向槽210滑动配合。如此设计，有利于限制所述定位块82的移动方向，使得定位块82靠近定位齿条81时，固定齿821可以对准定位齿条81，更容易调整滑块定位机构8的固定位置。
所述滑块定位机构8还包括滚轮84，滚轮84可转动地安装所述滑块壳体21内，与所述立柱1滚动配合，便于调整滑块壳体21在立柱1上的安装位置。一实施例中，滚轮84的数量为四个，均匀分布于立柱1的四周，但不限于此。
所述把手85的一端设有转动凸台851，通过该转动凸台851可转动地安装于所述滑块壳体21。该转动凸台851结构非常简单，既可以固定住把手85的一端，又可以实现把手85的转动，使用非常方便。
一实施例中，所述把手85的另一端设有柱状凸起852，所述定位块82设有装配凹槽825，所述柱状凸起852插入所述装配凹槽825中以连接所述定位块82。该实施例结构简单，容易装配，只需要将把手85上的柱状凸起852插入定位块82的装配凹槽825中即可，非常方便。但不限于 此，在其他实施例中，所述把手85的另一端可以通过销子或铆钉与所述定位块82连接，同样非常方便实用。
进一步地，所述固定齿821为方形齿，所述定位齿条81的齿形与固定齿821的齿形相适应。方形齿的接触面积大，受力点不会集中在某一点，从而滑块壳体21可以稳固地固定在立柱1上的某一位置。
所述固定齿821的齿数越多，则固定齿821与定位齿条81之间的咬合越牢固，也就是滑块壳体21固定在立柱1上越稳固，则对于安装于悬臂3上的伞篷4的承受能力越强。优选地，所述固定齿821的齿数为三个，但不限于此，也可以是两个，或四个、或五个等等，本实用新型对此不作限制。
以上所述仅为本实用新型的优选实施例，并非因此即限制本实用新型的专利保护范围，凡是运用本实用新型说明书及附图内容所作的等效结构变换，直接或间接运用在其他相关的技术领域，均同理包括在本实用新型的保护范围内。
