Description

一种帐篷架杆的改进结构 技术领域
本发明涉及一种帐篷，特别是指一种帐篷架杆的改进结构。
背景技术
现有技术中较具代表性的帐篷是由帐篷支架加篷布组成，帐篷支架一般都包括有若干根支杆，各支杆的顶端通过一顶模块相互枢接在一起，各根支杆又均由至少两根管件组成，每个管件之间通过折叠关节连接在一起。
现有的一种帐篷架杆结构包括多根立杆和篷顶支架，立杆为伸缩杆，立杆和篷顶支架的顶部都直接与帐篷布接触并对帐篷布形成支撑，篷顶支架与每根立杆之间都连接有支撑顶杆组，每两根相邻的立杆之间都连接有侧顶杆组，每根立杆和与该立杆连接的每组侧顶杆组之间还连接有斜支杆，由于帐篷都是于户外使用，其结构必须便于收折携带，因此，该帐篷连接两立杆顶部的侧顶杆组是包括至少两根杆件及枢接件相互枢接。
上述现有的帐篷至少存在以下的不足：
首先，帐篷作为一种户外休闲用品，其空间越大，用户体验效果越好，上述帐篷支架的支撑顶杆组或者侧顶杆组常采用对称设置的交叉杆组，在两组相互铰接的交叉杆组的枢接处会形成一个往下的枢接点，这样会影响帐篷内部的空间，使帐篷空间变小。
其次，帐篷布在重力作用下容易形成凹坑，特别是高顶帐篷在雨天使用时，帐篷布于中心干与侧顶杆组的中间位置更容易在雨水的冲击下内凹形成积水，加重帐篷骨架的负重，在拆卸帐篷时也容易被积水溅到，影响帐篷的使用寿命。
再者，由于侧顶杆组是由至少两杆件枢接，上述帐篷内凹积水后，侧顶杆组的受力点全部移至两杆件的枢接点，即枢接件必须承受帐篷布及积水的重量，因此该枢接件极易折断，影响帐篷的使用寿命，这也是当下帐篷返修率相当高的部位，迫切需要改善。有些帐篷的侧杆组是采用相互对称的两根连杆铰接形成的连杆单元进行连接，但是这种结构的帐篷容易晃动，帐篷的稳定性不佳。
有鉴于此，本设计人针对上述帐篷结构设计上未臻完善所导致的诸多缺失及不便，而深入构思，且积极研究改良试做而开发设计出本发明。
发明内容
本发明的目的在于提供一种帐篷内部空间较大且帐篷布不易积水的帐篷架杆的改进结构。
本发明的另一目的在于提供一种帐篷稳定性较好的帐篷架杆的改进结构。
为了达成上述目的，本发明的解决方案是：
一种帐篷架杆的改进结构，其包括多根立杆、设置在帐篷顶部中心的顶模、连接相邻两立杆的多组侧杆组、以及连接各侧杆组与顶模的多组顶杆组；立杆的顶端安装有固定座，立杆的杆身上安装有可沿立杆滑动的滑动座，顶模上设有上连接巢及下连接巢，各组侧杆组包括两组一端相互铰接的连杆单元，各顶杆组包括一组连杆单元，各侧杆组的各连杆单元分别包括相互铰接且展开呈'X'型的一长杆及一短杆，侧杆组的两组连杆单元中的两根短杆一端相互铰接，形成下铰接点，两短杆的另一端分别铰接在相邻两根立杆的固定座上，侧杆组的两组连杆单元中的两根长杆一端相互铰接，形成上铰接点，另一端铰接在相邻两立杆的滑动座上，顶杆组的连杆单元包括两根相互铰接且展开呈'X'型的两连杆，其中一连杆一端与侧杆组的下铰接点铰接，另一端与顶模的上连接巢铰接，顶杆组的另一根连杆一端与侧杆组的上铰接点铰接，另一端与顶模的下连接巢铰接。
帐篷展开后，各侧杆组相互铰接的两连杆单元的两短杆形成180度的夹角，各侧杆组的两长杆夹角小于两短杆形成的夹角。
各侧杆组的各连杆单元的长杆及短杆的铰接点设于长杆与短杆的中心点处。
各侧杆组的两连杆单元呈对称设置，每一连杆单元的长杆及短杆的铰接点设于靠近立杆的一侧。
各侧杆组的两连杆单元呈对称设置，每一连杆单元的长杆及短杆的铰接点设于靠近上铰接点及下铰接点的一侧。
所述顶杆组的连杆单元的两根连杆为相互铰接的一长杆及一短杆。
所述顶杆组的连杆单元为两根于中心点相互铰接的等长的连杆。
所述顶模为一中心杆，该中心杆上设有所述上连接巢及下连接巢。
所述上连接巢可滑动的设置在中心杆的杆身上，下连接巢固定在中心杆的底端。
采用上述结构后，本发明帐篷架杆主要是将侧杆组的各连杆单元分别设计成相互铰接且展开呈'X'型的一长杆及一短杆，这样可保证各侧杆组的两短杆展开后的夹角大于两长杆展开后的夹角，且由于短杆是铰接在立杆的固定座上，可使得展开后的侧杆组两连杆单元的上、下铰接点会往上抬，而不会下陷，顶杆组的两连杆分别与上、下连接巢及侧杆组的上、下铰接点铰接，可使顶杆组的连杆单元与侧杆组的上、下铰接点保持一致，通过侧杆组连杆单元的不对称设计，可使得帐篷内部的空间增大，从而提高用户体验。并且将侧杆组的上铰接点上抬后会将帐篷布往上顶起，避免帐篷布下陷，从而可避免帐篷布积水。
特别是，当本发明的各侧杆组的两短杆若形成180度的直线状态时，两根短杆将相邻的两根立杆顶死，可避免帐篷产生晃动，因此帐篷的整体稳定性更好。

具体实施方式
为了进一步解释本发明的技术方案，下面通过具体实施例来对本发明进行详细阐述。
如图1至图7所示，本发明揭示了一种帐篷架杆的改进结构，其包括多根立杆1、设置在帐篷顶部中心的顶模2、连接相邻两立杆1的多组侧杆组3、以及连接各侧杆组3与顶模2的多组顶杆组4；立杆1的顶端安装有固定座11，立杆1的杆身上安装有可沿立杆1滑动的滑动座12，顶模2上设有上连接巢21及下连接巢22，各组侧杆组3包括两组一端相互铰接的连杆单元31，各顶杆组4包括一组连杆单元41，各侧杆组3的连杆单元31分别包括相互铰接且展开呈'X'型的一长杆311及一短杆312，及各顶杆组4的连杆单元包括两根相互铰接且展开呈'X'的连杆411、412，侧杆组3的两组连杆单元31中的两根短杆312一端相互铰接，形成下铰接点313，两短杆312的另一端分别铰接在相邻两根立杆1的固定座11上，侧杆组3的两组连杆单元31中的两根长杆311一端相互铰接，形成上铰接点314，另一端铰接在相邻两立杆1的滑动座12上，顶杆组4的其中一连杆411一端与侧杆组3的下铰接点313铰接，另一端与顶模2的上连接巢21铰接，顶杆组4的另一连杆412一端与侧杆组3的上铰接点314铰接，另一端与顶模2的下连接巢22铰接。
本发明关键在于：将侧杆组3的各连杆单元31分别设计成相互铰接且展开呈'X'型的一长杆311及一短杆312，这样可保证各侧杆组3的两短杆312展开后的夹角大于两长杆311展开后的夹角，且由于短杆312是铰接在立杆1的固定座11上，可使得展开后的侧杆组3两连杆单元31的上、下铰接314、313点会往上抬，而不会下陷，顶杆组4的两连杆411、412分别与上、下连接巢21、22及侧杆组3的上、下铰接点314、313铰接，可使顶杆组4的连杆单元41与侧杆组3的上、下铰接点314、313保持一致，通过侧杆组3连杆单元31的不对称设计，可使得帐篷内部的空间增大，从而提高用户体验。并且将侧杆组3的上铰接点314上抬后会将帐篷布往上顶起，避免帐篷布下陷，从而可避免帐篷布积水。
为了增加帐篷的稳定性，各侧杆组3相互铰接的两连杆单元31的两短杆312形成180度的夹角，各侧杆组3的两长杆311夹角小于两短杆312形成的夹角。这样，两根短杆可将相邻的两根立杆顶死，可避免帐篷产生晃动，因此帐篷的整体稳定性更好。
如图3所示，各侧杆组3的各连杆单元31的长杆311及短杆312的铰接点315可设于长杆311与短杆312的中心点处。
如图4所示，各侧杆组3的两连杆单元31呈对称设置，每一连杆单元31的长杆311及短杆312的铰接点315设于靠近立杆1的一侧，各顶杆组的长杆及短杆的铰接点设于靠近侧杆组的一侧，这样形成的上铰接点314高度较高，防积水的效果较好。
如图5所示，各侧杆组的两连杆单元31呈对称设置，每一连杆单元31的长杆311及短杆312的铰接点315设于靠近上铰接点314及下铰接点313的一侧，此种方式，侧杆组3形成的上铰接314上抬的高度较小，防积水的效果相较于图3及图4所示的实施例较差一些。
本发明各顶杆组4的连杆单元41的两根连杆411、412可为与侧杆组3相同的两根相互铰接的一长杆及一短杆。也可采用两根等长的连杆相互铰接形成连杆单元41，该连杆单元的两根连杆41可于各连杆411、412的中心点铰接。
如各图所示，本发明的较佳实施例中，所述顶模2为一中心杆，该中心杆上设有所述上连接巢21及下连接巢22。上连接巢21可滑动的设置在中心杆的杆身上，下连接巢22固定在中心杆的底端。
上述实施例和图式并非限定本发明的产品形态和式样，任何所属技术领域的普通技术人员对其所做的适当变化或修饰，皆应视为不脱离本发明的专利范畴。
