以下结合附图和具体实施例对本发明进行详细描述，但不作为对本发明的限定。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，下面结合实施例及附图，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
图1为本发明一实施例中具有助力把手的冰箱的示意图；图2为图1中助力把手的分解示意图；图3为图1中助力把手在初始状态时的剖面示意图；图4为图1中助力把手在打开状态时的剖面示意图。
如图1所示，冰箱10包括门体1、箱体2及设置于门体1上的助力把手3，门体1的一侧枢接于箱体2，门体1可经由助力把手3相对箱体2打开，门体1还可闭合于箱体2上。
如图1至图4所示，助力把手3包括拉手杆31、推块4以及推杆5，拉手杆31上设置枢转轴33；推块4上设置枢转孔41，枢转轴33容置于枢转孔41中；其中，枢转孔41为跑道孔，当助力把手3处于初始状态时，枢转轴33位于跑道孔的第一端；当助力把手3的拉手杆31被拉开，枢转轴33带动推块4转动，枢转轴33移动至跑道孔的第二端，推块4的推抵端43推抵推杆5的前端，推杆5的后端朝向箱体2伸出并推抵箱体2，门体1相对箱体2打开。
推杆5的前端为靠近使用者的一端，推杆5的后端为远离使用者的另一端。
如图2所示，拉手杆31相对的两端分别设置弯折部32，弯折部32朝向推块4延伸，弯折部32上延伸装配凸起321，枢转轴33结合于装配凸起321上。
枢转孔41及推抵部43分别位于推块4相对两端部。其中，推块4还包括装配孔42，装配孔42与枢转孔41相互连通。弯折部32上的装配凸起321插入装配孔42中，枢转轴33进入枢转孔41中。
本实施例中，枢转孔41的数量例如是两个，两个枢转孔41分布于装配孔42的上侧与下侧，且分别与装配孔42相互连通。枢转轴33相对的两个端部分别突出于装配凸起321的上下表面，而容置于对应的枢转孔41中。
如图2与图3所示，枢转轴33与推块4的枢转孔41装配后，拉手杆31处于初始状态时，推杆4与装配凸起321处于同一直线上。枢转轴33位于枢转孔41的第一端，第一端靠近推块4的推抵端43。
如图2与图4所示，拉开拉手杆31，装配凸起321上的枢转轴33在推块4的枢转孔41中转动，同时，弯折部32朝向门体1倾斜，带动枢转轴33在枢转孔41的滑动，推动推块4转动，枢转轴33移动至枢转孔41的第二端，第二端与第一端相对。此时，推块4与弯折部32之间形成一夹角，夹角例如是钝角。推块4的推抵端43推抵推杆5的前端，并使得推杆5的后端伸出推抵箱体2。
拉手杆31与门体1之间设置基座7，基座7包括相互连通的第一容置部701与第二容置部702，第一容置部701位于门体1的前侧，第二容置部702位于门体1的侧边。其中，弯折部32、枢转轴33及推块4分别收纳于第一容置部701中；推杆5及复位弹簧6分别收纳于第二容置部702。
第一容置部701的前侧结合外盖8，外盖8上设置开孔81，弯折部32穿过开孔81进入第一容置部701中。
推杆5被推块4的推抵端43推动在第二容置部702中移动，推杆5上设置第一滑动部51，第二容置部702中设置第二容置部73，第一滑动部51例如是滑块，第二滑动部73例如是滑槽，滑块插入滑槽中，使得推杆5沿着第二容置部702进行滑动。在本发明其他实施例中，第一滑动部也可以是滑槽，第二滑动也可以是滑块。
推杆5与第二容置部702之间设置复位弹簧6，复位弹簧6相对的两端分别设置套设于第一定位柱72与第二定位柱52上，第一定位柱72形成于第二容置部702中的凸块71上，第二定位柱52设置于推杆5朝向第二容置部702的一侧。其中，第一定位柱72与第二定位柱52相对。
当拉动拉手杆31，弯折部32的装配凸起321中的枢转轴33在推块4的枢转孔41中转动，同时，弯折部32上枢转轴33从枢转孔41的第一端移动至第二端，使得推块4转动，推低端43推抵推杆5的前端，推杆5的第一滑动部51沿着第二容置部702中的第二滑动部73滑动，推杆5的远端伸出第二容置部702并推抵箱体2，此时，复位弹簧6被推杆5压缩。当松开拉手杆31，复位弹簧6从压缩态朝向伸展状态，提供弹性力作用于推杆5，推杆5的前端推抵推块4的推抵端43，推块4转动，带动枢转轴33移动至枢转孔41的第一端，弯折部32从倾斜位置恢复至与推块4位于同一直线上的位置，弯折部32带动拉手杆31恢复至初始位置。
上述推块4实质上相当于杠杆，即，拉手杆31拉开时，推块4被枢转轴33带动顺时针转动推抵推杆5的前端；其中，施加到拉手杆31拉力的力臂与作用到推杆5上推力的力臂成正比，因此，推块4是一个省力杠杆，使得助力把手3具有省力作用。
如图2至图4所示，推块4靠近推抵端43的位置具有斜面44，斜面44为推块4在第一容置部701中转动提供了转动空间，使得推块4转动推抵推杆5前端的过程更顺畅。另外，由于斜面44的存在，第一容置部701预留的供推块4转动的空间可缩减，有利于基座7的小型化，提升美观度。较佳的，斜面44靠近推抵部43设置。
第一容置部701中设置凸块74，在推块4转动的过程中，凸块7始终与推块4的后侧壁相互抵靠，提升推块4转动稳定性。
综上，本发明提出一种助力把手及冰箱，助力把手包括拉手杆、推块及推杆，拉手杆与推块相枢接，拉手杆上的枢转轴在推块的跑道孔中枢转，并带动推块转动，使得推块的推低端推动推杆的前端，推杆的后端朝向冰箱的箱体伸出，将门体从箱体上打开。由于推块作为杠杆使用，使得施加到拉手杆拉力的力臂与作用到推杆上推力的力臂成正比，实现助力把手省力作用。
综上，本发明提供一种助力把手及冰箱，助力把手的助力结构采用枢接的多个杠杆及连杆，一方面，延长了作用于推杆的力臂，实现省力效果；另一方面，在拉手杆较长的情况下，使得使用者拉动拉手杆的距离较小，避免出现需要使用者大力拉动拉手杆的现象。此外，将拉手杆设置成多个把手部联动的结构有助于实现更佳的省力效果。
当然，本发明还可有其他多种实施例，在不背离本发明精神及其实质的情况下，熟悉本领域的技术人员可根据本发明作出各种相应的改变和变形，但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
