本发明的拉杆式行李箱的拉杆具有提手位置、推行位置和拉行位置，在提手位置时拉杆可以直接用作提手，从而箱体不需要再另行装配行李箱提手，简化了设计，节约重量和成本，同时在推行位置便于箱体的推行，三级位置便于行李箱拉行。
此外，由于拉杆的竖杆设置于箱体框架的两侧(这种设置使得拉杆与普通拉杆箱的拉杆相比，显得拉杆的两个竖杆之间的距离更宽，因此称为宽拉杆)，拉杆的横杆设置于框架的顶部并且当拉杆未拉出时横杆完全嵌入箱体里面，可以实现纯平的顶部，此时顶部可以用来放置笔记本操作，使用者也可以坐在箱体顶部，坐起来 很舒服。
其次，由于拉杆的竖杆设置于箱体框架两侧，可以让箱子里面，两个面都是纯平的，因此，拉杆不会占用箱体的有效利用空间，从而可以节约很多内部空间(传统的拉杆会侵占很多背部空间)，使得箱体内的使用空间更大，便于存放更多的物品。
再次，由于宽拉杆在使用过程中，例如需要将拉杆箱携带上下楼梯等，可以胳膊穿进去，方便提拉操作，节约体力。
最后，宽拉杆的内管是一根一体化弯管，不会断裂，而传统拉杆是使用两根管子通过一个横梁链接，容易断裂。

具体实施方式
以下将结合附图对本发明的较佳实施例进行详细说明，以便更清楚理解本发明的目的、特点和优点。应理解的是，附图所示的实施例并不是对本发明范围的限制，而只是为了说明本发明技术方案的实质精神。
在下文的描述中，出于说明各种公开的实施例的目的阐述了某些具体细节以提供对各种公开实施例的透彻理解。但是，相关领域技术人员将认识到可在无这些具体细节中的一个或多个细节的情况下来实践实施例。在其它情形下，与本申请相关联的熟知的装置、结构和技术可能并未详细地示出或描述从而避免不必要地混淆实施例的描述。
在整个说明书中对“一个实施例”或“一实施例”的提及表示结合实施例所描述的特定特点、结构或特征包括于至少一个实施例中。因此，在整个说明书的各个位置“在一个实施例中”或“在一实施例”中的出现无需全都指相同实施例。另外，特定特点、结构或特征可在一个或多个实施例中以任何方式组合。
在以下描述中，为了清楚展示本发明的结构及工作方式，将借助诸多方向性词语进行描述，但是应当将“前”、“后”、“左”、“右”、“外”、“内”、“向外”、“向内”、“上”、“下”等词语理解为方便用语，而不应当理解为限定性词语。
图1-3是本发明拉杆箱100的主视图，其示拉杆分别处于提手位置、推行位置以及拉行位置的状态，图4是本发明拉杆箱100的侧视图。如图1-4所示，拉杆箱100包括箱体20和拉杆10，根据拉杆10从箱体20伸出的长度不同拉杆依次具有提手位置A、推行位置B以及拉行位置C，当拉杆10处于提手位置A时，通过拉杆10能够将箱体20提起。
当拉杆10处于提手位置A时，拉杆10从箱体20内伸出的第一长度最短。当拉杆10处于拉行位置C时，拉杆10从箱体20内伸出的第三长度最长。当拉杆10处于推行位置B时，拉杆10从箱体20内伸出的第二长度位于第一长度和第三长度之间。
图5示出拉杆箱100的立体图，图6示出图5的拉杆箱的箱体20的立体图，其中，拉杆已经被拆下，图7示出拉杆箱100的又一立体图，其中拉杆未被拉起，如图5-7所示，拉杆箱100包括位于四周的框架21以及位于箱体框架21的前表面的前面板22和位于箱体框架21的后表面的后面板23，框架21、前面板22和后面板23合围成箱体20。拉杆10包括横杆12和竖杆11，横杆12位于箱体框架21的顶部以及竖杆11位于箱体框架21的两侧。通过图5可以清楚看出，本发明的拉杆 与普通的拉杆箱相比，拉杆的横杆要长得多，大致与箱体等宽，因此也称作宽拉杆。
如图6-7所示，在框架的顶部设有凹槽23，当拉杆10未被拉出时，横杆12嵌入凹槽23内，从表面上看，拉杆10与箱体20结合成一体，整个拉杆箱外观非常简洁。
图8示出本发明一个实施例中的拉杆箱100A的立体分解图，在图8所示的实施例中，前面板22和后面板23可拆卸地连接在箱体框架21的前表面和后表面。此种方式便于箱体面板的更换，用户还可以根据个人喜好更换不同颜色的面板。
继续参见图1-8，作为一种优选的方式，拉杆10的竖杆11位于箱体框架21两侧的中部。如此设置，便于当拉杆10处于提手位置时提起拉杆箱100，并且由于拉杆10处于箱体框架的中部，因此，提起时便于保持箱体的平衡。
在一个实施例中，箱体框架21包括相互独立的第一部分(即箱体主体)和第二部分(即箱盖)，第一部分和第二部分之间通过铰链可转动地连接。其中，第一部分的厚度大于箱体框架第二部分的厚度，拉杆设置于箱体框架21的第一部分(即箱体主体)上，其中，竖杆设置于箱体框架21的第一部分的两侧，横杆设置于第一部分的顶部。
如图5所示，拉杆12的中部设有控制键121，操作该控制键121使得拉杆处于提手位置A、推行位置B或拉行位置C。虽然图中示出控制键121处于横杆12的中部，然而，本领域的技术人员可以理解，控制键也可以设置在拉杆的其他位置。图示的实施例中，控制键121通过按压的方式操作。当拉杆10未从箱体20内拉出时，拉杆10完全嵌入箱体20内。
当拉杆10未从箱体20拉出时，按压一下控制键121，可以将拉杆移动到提手位置A，再次按压控制键121，可以将拉杆12从提手位置A移动到推行位置B，再次按压控制键121，可以将拉杆从推行位置B移动到拉行位置C。
下面参照图9-12发明的拉杆10进行说明。图9是拉杆10的立体图，图10是拉杆10的剖视图，图11是图10的E部分的放大图，图12是拉杆10的立体分解图。如图9-11示，拉杆10包括把手组件13、传动组件14、内管15、外管16以及档位组件15，内管15包括一体形成的顶部的横管151和两侧的立管152，传动组件14安装于内管15内，把手13安装于内管15的顶部横管151外，内管15两侧的立管152分别容纳于两根外管16内，档位组件15安装于外管16的底部并与传动组件14配合，把手13与传动组件14联动并通过传动组件14驱动档位组件15 运动，从而使得拉杆10分别处于提手位置、推行位置或拉行位置。由于内管15是一根一体化弯管，不易断裂，而传统拉杆使用两根管子通过一个横梁链接，则容易断裂。
具体地，把手13包括把手上部131和把手下部132，把手上部131和把手下部132分别安装于内管15的顶部横管151的上方和下方，并相互扣合从而将内管15的顶部横管151容纳于把手13的内部。控制键17安装于把手的中部，具体地，把手上部131的中部设有控制键槽(图未示)，控制键17容纳于控制键槽内。
传动组件14包括传动杆141、拐角传动块142、钢线143以及传动脚144，传动杆141安装于内管15的顶部横管151内，拐角传动块142的下端与钢线的上端连接，拐角传动块142的上端与传动杆141的端部配合，钢线143安装于内管15的立管152内并在下端连接传动脚144，传动杆141的运动通过拐角传动块142传递给钢线143，从而带动传动脚144运动。
外管16从下往上设有分别拉杆的未伸出位置、提手位置、推行位置以及拉行位置对应的孔161、162、163和164，档位组件15的定位件152分别与孔161、162、163、164配合从而使得拉杆位于未伸出位置、提手位置、推行位置和拉行位置。
档位组件15包括换向件151、定位件152、限位件153以及第一弹性件154，限位件153沿竖直方向设有限位件安装槽1531以及沿水平方向设有定位件安装槽1532，换向件151安装于限位件安装槽1531内且换向件151的上端与传动角块144的下表面接触，第一弹性件154和定位件152安装于定位件安装槽1532内且第一弹性件154位于定位件152的后方，定位件152在第一弹性件154的弹力作用下能够向限位件153的外部凸出从而容纳于分别与未伸出位置、提手位置、推行位置或拉行位置对应的外管16的孔161、162、163、164内。
换向件151的下端设有导向斜面1511，定位件152设有与导向斜面配合的换向斜面1521，当换向件151向下运动时，导向斜面1511与换向斜面1521配合从而迫使定位件152向后运动退回限位件153的内部。
档位组件15还包括第二弹性件155以及封头件156，封头件156固定安装于外管16下端的内部，第二弹性件155的上端与限位件153的底表面接触并支撑限位件153，第二弹性件155的下端安装于封头件156上。具体地，封头件156的丁端面上设有凸出部1561，第二弹性件155安装于凸出部1561上。
继续参照图10-11，换向件151设有沿竖直方向延伸的导向槽1513，导向槽1513 通过销1514安装在限位件153的换向件安装槽1531内，换向件151可沿销1514上下滑动。换向件151的侧面设有限位台阶1512，限位台阶1512与限位件153内的挡板1533配合，使得换向件151只能在限位件153内进行一定距离的竖直运动，该运动的行程即导向槽1531的深度。
定位件152的前端设有凸出部1522，该凸出部1522的尺寸与外管16上与拉杆未伸出位置、提手位置、推行位置以及拉行位置对应的孔161、162、163、164配合，从而在第一弹性件154的驱动下能够进入相应的孔161、162、163、164内。
图13-15示出拉杆10与箱体20的连接状态。图13是拉杆箱100的主视图，图14是沿图13的线A-A剖开的剖视图，图15是沿图13的线K-K剖开的剖视图。如图13-15所示，拉杆10通过分别通过位于上部的螺钉31和位于下部的螺钉32固定在箱体20内，其中，上部的螺钉31通过将外管16固定在箱体内固定拉杆，下部的螺钉32通过将固定件157固定在箱体内固定拉杆。
拉杆处于未伸出位置时，定位件152的凸出部1522容纳在外管16上的第一孔161内，当需要将拉杆拉出至提手位置时，按压控制键17，驱动传动杆141向下运动，该运动通过钢线143传递给传动脚144，传动脚144向下按压换向件151，换向件151向下运动并通过导向斜面1511与换向斜面1521的接触迫使换向件152克服第一弹性件154的弹力向后运动，从第一孔161内退出并退回到限位件153内，此时在第二弹性件155向上的弹力作用下整个限位件向上运动，并推动内管15向上运动，直到换向件152的凸出部1522运动到外管16的与提手位置对应的第二孔162，此时凸出部1522伸入第二孔162内限位，拉杆处于提手位置，不能再继续向上运动，此时握住把手13，可以将拉杆箱100提起，把手13起到了拉杆箱提手的作用。
需要推动拉杆箱时，再次按压控制键17，驱动传动杆141向下运动，该运动通过钢线143传递给传动脚144，传动脚144向下按压换向件151，换向件151向下运动并通过导向斜面1511与换向斜面1521的接触迫使换向件152克服第一弹性件154的弹力向后运动，从第二孔161内退出并退回到限位件153内，此时即可向上拉动把手使拉杆继续向上运动，直到换向件152的凸出部1522运动到外管16的与推行位置对应的第三孔163，此时凸出部1522伸入第三孔163内被限位，拉杆处于拉行位置，不能再继续向上运动，此时便于推动拉杆箱。、
当需要将拉杆变换到拉行位置时，操作方法和原理与上面的方法相同，此处不 再赘述。
此外，通过上文的描述可以清楚知道，在本实施例中，拉杆10的顶部横杆12包括把手13、传动杆141、拐角传动块142以及内管15的顶部横管151，而竖杆11在外延包括内管15的竖管152、外管16以及容纳于外管16和竖管152内的部分。
作为一种比较优选的方案，上述实施例中的第一弹性件和第二弹性可以是弹簧。然而，本领域的技术人员可以理解，第一弹性件和第二弹性件也可以选用本领域中常用的其它弹性装置。
本发明的拉杆式行李箱，拉杆的竖杆设置于箱体框架的两侧，同时拉杆具有提手位置、推行位置和拉行位置，在提手位置时拉杆可以直接用作提手，从而箱体不需要再另行装配行李箱提手，简化了设计，同时在推行位置便于箱体的推行，三级位置便于行李箱拉行。
以上已详细描述了本发明的较佳实施例，但应理解到，在阅读了本发明的上述讲授内容之后，本领域技术人员可以对本发明作各种改动或修改。这些等价形式同样落于本申请所附权利要求书所限定的范围。
