本申请提出一种折叠式支架，适用于支撑乐谱、书本或文件夹等物品。
参考图1和图2，在本申请一实施例中，该折叠式支架包括脚架组件10、拉杆组件20和承托组件30；拉杆组件20具有相对的第一端和第二端，脚架组件10设于拉杆组件20的第一端上；承托组件30可折叠地设置于拉杆组件20的第二端上，承托组件30具有展开状态和收拢状态；在展开状态时，承托组件30打开并形成用于承托物品的承托面101，如图2所示；在收拢状态时， 承托组件30合拢并整体构成杆状结构，如图1所示。
本实施例中，脚架组件10可为三脚架或多脚架等，用于将拉杆组件20和承托组件30支撑于地面或桌面上，脚架组件10可滑动套设于拉杆组件20的下端。
拉杆组件20可包括多个拉伸杆，能够调节支撑高度，以方便用户使用。
承托组件30可包括多个支杆或支撑板，可通过旋转机构、滑动机构、铰接机构等实现承托组件30在展开状态和收拢状态之间切换，此处不做具体限定。
本实施例中，承托组件30可包括主支架31、第一连杆组件32、第二连杆组件33和第三连杆组件34。需要说明，为了构成能够支撑起乐谱或书本等物品的承托面101，本折叠式支架的承托组件30可至少包括两连杆组件，即第一连杆组件32和第二连杆组件33，各连杆组件可间隔设置于主支架31上，此处，对连杆组件的数量不做限定。
本实施例中，主支架31通过旋转轴311旋转设置于拉杆组件20的第二端上。第一连杆组件32可转动设置于主支架31的顶部；第二连杆组件33可转动设置于主支架31的中部；第三连杆组件34可转动设置于主支架31的底部。在展开状态时，第一连杆组件32、第二连杆组件33和第三连杆组件34展开并形成承托面101；在收拢状态时，第一连杆组件32、第二连杆组件33和第三连杆组件34分别贴靠于主支架31上并构成杆状结构。
在本申请的技术方案中，该折叠式支架包括脚架组件10、拉杆组件20和承托组件30；拉杆组件20具有相对的第一端和第二端，脚架组件10设于拉杆组件20的第一端上；承托组件30可折叠地设置于拉杆组件20的第二端上，承托组件30具有展开状态和收拢状态；在展开状态时，承托组件30打开并形成用于承托物品的承托面101；在收拢状态时，承托组件30合拢并整体构成杆状结构。如此，实现了可折叠收纳和展开，用户携带便利、使用方便，也有利于厂家包装和转运。
需要说明，由于承托组件30可折叠地设置于拉杆组件20上，在合拢承托组件30后，如图1所示，可进一步地折叠收纳于拉杆组件20的一侧，尽可能地缩小了整个支架收纳后的长度大小。
为了进一步地提高该支架收纳和展开的便利性，并提升其支撑物品的稳 定性，参考图2至图10，在一实施例中，第一连杆组件32包括第一顶杆321和第二顶杆322，第一顶杆321和第二顶杆322分别转动设置于主支架31的顶部。第二连杆组件33包括第一中杆331和第二中杆332，第一中杆331和第二中杆332分别转动设置于主支架31的中部。第三连杆组件34包括第一底杆341和第二底杆342，第一底杆341和第二底杆342分别转动设置于主支架31的底部。
参考图10，在展开状态时，第一顶杆321、第一中杆331和第一底杆341分别位于主支架31的同一侧，第二顶杆322、第二中杆332和第二底杆342分别位于主支架31的另一侧，以展开形成承托面101。
主要参考图5，在收拢状态时，第一顶杆321、第二顶杆322、第一中杆331、第二中杆332、第一底杆341和第二底杆342分别贴靠于主支架31上，以使承托组件30构成杆状结构。
主要参考图8，本实施例中，第一中杆331和第二中杆332均可为拉伸杆，以调节承托面101的长度大小来匹配不同长度的物品。如此，可以满足更多规格的乐谱、书本或文件夹等物品的支撑需求，提高了该折叠式支架的适用性。
如图2所示，在一实施例中，承托组件30还可包括夹紧组件，夹紧组件包括用于夹紧物品两侧边缘的第一压紧件和第二压紧件，第一压紧件设于第一中杆331的端部，第二压紧件设于第二中杆332的端部。
本实施例中，第一压紧件和第二压紧件均包括上壳411、下壳412、压块413和扭转弹簧，上壳411固定于拉伸杆的表面，上壳411与下壳412连接并固定于拉伸杆的背面，上壳411设有供扭转轴两端插设的两插孔，扭转弹簧套设于转动轴上且其一端与压块413抵接，扭转弹簧的另一端与上壳411抵接，压块413的端部与上壳411通过扭转轴连接。如此，可进一步地提升该折叠式支架支撑物品的稳固性，能够有效地避免物品滑落。
本实施例中，压块413可采用亚克力等透明材质，以在夹持乐谱或书本等物品的边缘时，能够有效地透过夹紧组件查看其下方遮挡的文字或图片等内容，极大地提升了用户使用体验。
为了进一步地提升该折叠式支架的适用性，以适配更多规格的物品，参考图2和图3，在一实施例中，主支架31沿其长度方向设有滑槽31a，第一 顶杆321和第二顶杆322的端部通过滑动旋转机构滑动设置于滑槽31a中，以调节承托面101的宽度大小来匹配不同宽度的物品。
主要参考图3，本实施例中，滑动旋转机构可包括滑动设置于滑槽31a内的滑动块51、第一齿块52和第二齿块53和第一固定块54，第一齿块52的一端与第一顶杆321固定，第一齿块52的另一端通过第一转轴可转动地固定于滑动块51与第一固定块54之间，第二齿块53的一端与第二顶杆322固定，第二齿块53的另一端通过第二转轴可转动地固定于滑动块51与第一固定块54之间。如此，可在实现第一连杆组件32折叠收纳和展开功能同时，也提升了支架的适用性。
在使用时，结合图1和图5，可先将承托组件30向上转动打开，并将脚架组件10向下滑动打开，将脚架组件10置于地面上；参考图5和图6，再将第一顶杆321和第二顶杆322旋转打开；参考图6和图7，然后将第一底杆341和第二底杆342旋转打开；参考图7和图8，将第一中杆331和第二中杆332旋转打开；参考图8和图9，再根据物品的长度，拉伸第一中杆331和第二中杆332的长度，以调节承托面101的长度；参考图9和图10，再根据物品的宽度，滑动第一顶杆321和第二顶杆322，以调节承托面101的宽度；最后，再将乐谱等物品放置于承托面101上，并分别用第一压紧件和第二压紧件夹紧物品的两侧边即可。
参考图3，在一实施例中，滑动旋转机构还可包括两摩擦块55，滑动块51包括滑动上壳和滑动下壳，滑动上壳与滑动下壳围设形成安装腔，两摩擦块55置于安装腔，且安装腔的两侧槽壁分别设有供两摩擦块55外端通过的避让口，两摩擦块55的一端套设有弹性件56，两摩擦块55的另一端与滑槽31a的两槽壁分别抵接。
可以理解的是，通过设置摩擦块55与滑槽31a的槽壁弹性抵接，可以用于保护滑动块51，以避免滑动块51在滑动过程中与滑槽31a的槽壁产生磨损，提高了滑动块51使用寿命，并能够满足滑动块51在滑槽31a内滑动的顺畅性。
参考图2，在一实施例中，第一底杆341和第二底杆342均设有用于托举物品底部的托板343，以进一步地提升该折叠式支架支撑物品的稳定性。
为了实现第三连杆组件34的收纳和展开功能，参考图2和图4，在一实 施例中，第一底杆341和第二底杆342的端部通过旋转组件设置于主支架31上，旋转组件包括设于主支架31上的支撑块61、第三齿块62、第四齿块63和第二固定块64，第三齿块62的一端与第一底杆341固定，第三齿块62的另一端通过第三转轴可转动地固定于支撑块61与第二固定块64之间，第四齿块63的一端与第二底杆342固定，第四齿块63的另一端通过第四转轴可转动地固定于支撑块61与第二固定块64之间。
同样地，本实施例中，第二连杆组件33也可采用与第三连杆组件34连接的旋转组件类似的连接结构，来实现旋转展开和收纳，此处不做具体限定。
参考图10，当承托组件30处于展开状态时，第一顶杆321和第二顶杆322的中心线可处于同一条线上并可与主支架31的中心线相垂直或略微倾斜；第一中杆331和第二中杆332的中心线可处于同一条线上并可与主支架31的中心线相垂直或略微倾斜；第一底杆341和第二底杆342的中心线可处于同一条线上并可与主支架31的中心线相垂直或略微倾斜。
参考图5，当承托组件30处于收拢状态时，第一顶杆321、第二顶杆322与主支架31的中心线相重合或平行；第一中杆331、第二中杆332与主支架31的中心线相重合或平行；第一底杆341、第二底杆342与主支架31的中心线相垂直或略微倾斜。
以上所述仅为本申请的可选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请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申请的专利保护范围内。
