具体实施方式
以下将结合附图所示的具体实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
以本实施方式中设置于冰箱的冷藏间室为例，如图1和图2，搁物架装置包括搁物架组件1、滑道组件2和同步组件3，其中，滑道组件2设置于冷藏间室箱体的后背板处，同步组件3设置于冷藏间室箱体的后背板上或滑道组件2上，搁物架组件1配合滑道组件2，可调整高度地设置于冷藏间室的储存空间中，并且搁物架组件1能够通过与同步组件3的配合，在调整高度过程中保持搁物架组件1整体平衡。搁物架组件1可为一个或多个，滑道组件2也可设置一条或多条。
如图1所示，在本实施方式中，滑道组件2在冷藏间室竖直方向上布置，当搁物架组件1装配于滑道组件2且相对滑道组件2静止时，搁物架组件1的搁架本体11为水平布置。在冷藏间室箱体的后背板为竖直设置时，搁架本体11垂直于后背板设置。如此，可使得放在搁架本体11上的物品更加稳定。
在本实施方式中，搁物架组件1可在滑道组件2上移动，即在冷藏间室箱体上沿竖直方向移动。多个搁物架组件1可通过移动来调整之间的间距，以及搁物架组件1和冷 藏间室箱体的顶板、底板的间距，以适应储存更多不同高度的物品。在此过程中，同步组件3通过与搁物架组件1两端连接，进而达到平衡搁物架组件1的效果，使得上下移动过程中更为平稳。
如图2所示，在本实施方式中，搁物架组件1包括搁架本体11和至少两个支架12。支架12分别固定在搁架本体11两侧，从而提升整体结构的稳定性。当然在其他实施方式中，也可以存在支架12为三个以上的情况，从而进一步保持搁架本体11在移动过程中的稳定性。
在本实施方式中，滑道组件2包括轨道槽21、止挡位22、滑动板23和弹性组件26。
进一步的，在本实施方式中，滑道组件2在搁架本体11两侧、配合支架12设置有第一滑道组件2a和第二滑道组件2b，可以理解的，第一滑道组件2a包括第一轨道槽21a和第一滑动板23a，第二滑道组件2b包括第二轨道槽21b和第二滑动板23b。如前所述，滑道组件2沿竖直方向布置，上述轨道槽21及滑动配合于轨道槽21内的滑动板23，同样沿竖直方向布置。
如图2和图3所示，止挡位22和滑动板23设置于轨道槽21的内部，滑动板23与轨道槽21滑动连接。
其中，轨道槽21沿竖直方向，间隔布置有至少两个止挡位22，并可根据可调搁物架装置应用的需要，控制其疏密程度，从而与支架12可选择地限位固定。在本实施方式中，止挡位22贴近轨道槽21后背面设置。当然，在其他实施方式中，止档位22也可以贴近轨道槽21的侧面设置。
在本实施方式中，在轨道槽21沿竖直方向布置时，止挡位22设置于条状止挡部220内，条状止挡部220贴近轨道槽21内后背面设置，如此，在保持止挡效果的同时，不影响滑动板23与轨道槽21发生相对运动，也能够方便拆卸和更换。当然也存在其他实施方式，如将止挡部220贴近轨道槽21内部两侧设置，同样能够实现对支架12进行止挡的效果。
进一步的，在本实施方式中，止挡部220下端设有托槽，能够与轨道槽21下端口固定，进而将轨道槽21下端封闭，起到对轨道槽21内部滑动板23限位的作用。进一步的，在轨道槽21内部两侧布置有滑轨211。当然，在其他如在轨道槽21内部两侧布置止挡位22的实施方式中，滑轨211可以固定于轨道槽21后背面。
在本实施方式中，滑轨211包括内轨2111和外轨2112，内轨2111和外轨2112之间通过滚珠滑动连接。内轨2111与滑动板23固定，外轨2112与轨道槽21内部侧壁固定连接。
其中，滑动板23在受力上下移动过程中，能够带动内轨2111并通过其与外轨2112之间的滚珠，进而与外轨2112及与其固定轨道槽21发生相对运动。
在本实施方式中，滑动板23内部设有与支架12上挂钩进行卡扣连接的滚轮235，滚轮235两端固定于滑动板23凹槽内，并且该滚轮235能够以其两固定端连线为轴旋转，滚轮235和挂钩的配合结构能够在搁物架组件1上下移动过程中提供滑动板23竖直方向的支持力。
进一步的，如图3，同样与滑动板23相连并为滑动板23提供作用力的，还有弹性组件26，弹性组件26具有第一端261和第二端262，弹性组件第一端261设置于轨道槽21顶端，弹性组件第二端262处于自由状态，可以通过施加拉力，引发弹性组件26弹性形变，进而拉动第二端262将其连接于滑动板23的顶端，为滑动板23朝向弹性组件26第一段261的弹性恢复力。
为保护弹性组件第二端262的外观及功能，弹性组件第二端262与滑动板23固定重叠部分设有固定片263，弹性组件第二端262、滑动板23上端以及固定片263对应位置上分别设置有大小相等的螺丝孔，通过螺丝固定形成一体结构，延长弹性组件26使用寿命。
在本实施方式中，轨道槽21还包括用于固定弹性组件26的弹性组件固定座213，弹性组件固定座213内设有一可容置弹性组件第一端261的收容部。在本实施方式中，收容部内设置有一横向杆，弹性组件26设置为中空缠绕状，横向杆插入中空部且两端固定连接弹性组件固定座213壳体，以使弹性组件26连接弹性组件固定座213。
进一步的，弹性组件固定座213可与轨道槽21的顶端卡扣连接，弹性组件固定座213与轨道槽21和止挡部220底部托槽构成一封闭空间，从而限制滑动板23的移动位置，防止其从轨道槽21上下端口脱离。该封闭结构内部固定有滑轨211、滑动板23、滑动板23内部的滚轮235以及与滑动板23相连的弹性组件26的第二端262。
如图2至图4所示，进一步的，将上述滑动板23安装于对应的轨道槽21内，使搁架组件1中支架12上的挂钩与滑动板23内部滚轮235形成配合，进而可以将搁架组件1装配于滑道组件2。可以理解的是，在搁物架组件1装配于滑道组件2，并到达相对静止状态后，轨道槽21与搁架本体11相垂直设置。搁架本体11通过支架12与滑动板23相对固定设置，滑动板23可滑动地装配于轨道槽21上。
如此，便可实现调整搁物架组件1过程中轻便省力的效果，然而在调整过程中可能出现两滑动板23位移不等，从而致使搁架本体11整体不平衡的现象，因此本实施方式中，搁物架装置进一步设置有同步组件3。
如图5所示，在本实施方式中，第一滑动板23a包括分别位于其上端及下端的第一上固定部231和第一下固定部232，第二滑动板23b包括分别位于其上端及下端的第二上固定部233和第二下固定部234，同步组件3包括第一张紧件311、第一滑轮321和第二滑轮322，第一张紧件311一端固定于第一上固定部231，另一端分别经过第一滑轮321和第二滑轮322，固定于第二下固定部234，如此，在第一滑动板23a向上运动时，通过第一滑轮321和第二滑轮322的传动，配合第一张紧件311的移动，使第二滑动板23b与第一滑动板23a保持运动方向及位移相同。
通过上述同步组件3的设置，即可解决在第一滑动板23a和第二滑动板23b在带动支架12两侧上下移动过程中，由于移动位置灵活，导致滑动板位移长度并不相等，支架12移动不同步以致与其相连接的搁架本体11倾斜，进而为用户带来不便的问题，同时通过设置第一张紧件311，为第一滑动板23a提供了竖直方向的拉力，从而使得第一滑动板23a在运动过程中，更为轻便，提升了用户体验。
更具体的，第一张紧件311包括位于第一上固定部231及第一滑轮321之间的第一段311a，以及位于第二滑轮322与第二下固定部234之间的第二段311b，举例来说，当第一滑动板23a沿竖直方向向上位移，位移长度为L0时，第一段311a缩短，长度为L0，由于第一滑轮321和第二滑轮322固定，两滑轮之间的距离恒定不变，第一张紧件311位于两滑轮之间的部分长度不变，因此，第二段311b伸长，长度同样为L0，从而保证了第二滑动板23b能够沿竖直方向位移与第一滑动板23a相同的长度L0。
优选的，如图2和图5所示，第一段311a与第二段311b沿竖直方向延伸，当然在其他实施方式中，轨道槽21以及其内部的滑动板23并非沿竖直方向布置时，第一段311a与第二段311b的延伸方向也可以为其他方向，只要是与第一滑动板23a和第二滑动板23b行进方向相同的方向，均可作为第一段311a和第二段311b的延伸方向。可以理解的，在本实施方式中，如若第一段311a和第二段311b并非沿竖直方向延伸，或者在其他轨道槽21并不沿竖直方向布置的实施方式中，如若第一段311a和第二段311b并不处于第一滑动板23a和第二滑动板23b的行进方向，那么第一张紧件311便会为与其相连的滑动板23提供沿水平方向或垂直于滑动板23行进方向的分力，从而导致滑动板23与轨道槽21发生挤压，产生更大的滑动摩擦力，不仅会缩短装置的使用寿命，还会使滑动过程变得十分困难。
在本实施方式中，为了进一步防止第一张紧件311与轨道槽21或滑动板23发生干涉，从而缩短第一张紧件311的使用寿命，进一步的，同步组件3包括第三滑轮323以及第四滑轮324，第一张紧件311一端固定于第一滑动板23a的第一上固定部231，另 一端分别通过第一滑轮321、第三滑轮323、第四滑轮324和第二滑轮322，固定于第二滑动板23b的第二下固定部234，其中，第一张紧件311除包括上述第一段311a和第二段311b以外，进一步的还包括，位于第一滑轮321与第三滑轮323之间的第三段311c、位于第三滑轮323与第四滑轮324之间的第四段311d，以及位于第四滑轮324与第二滑轮322之间的第五段311e。
优选的，为了避免第一张紧件311与搁物架装置其他组件发生干涉导致磨损，第四段311d沿竖直方向延伸，第五段311e沿水平方向延伸，当然在其他实施方式中，特别在滑道组件2并不沿竖直方向布置的实施方式中，第四段311d也可以沿其他方向延伸，只要保持其与滑道组件2中轨道槽21以及滑动板23平行，或与竖直方向具有其他避免干涉的角度均可，可以理解的，第五段311e在其他实施方式中也可以存在其他布置方式。
如图5所示，为了更好地保持第一滑动板23a和第二滑动板23b移动过程中的同步性，可以在第二滑动板23b的第二上固定部233和第一滑动板23a的第一下固定部232之间，布置与第一张紧件311、第一滑轮321和第二滑轮322，相对应的第二张紧件312、第六滑轮326和第五滑轮325，如此，第二张紧件312一端固定于第一下固定部232，另一端分别通过第五滑轮325、第六滑轮326，固定于第二上固定部233，其中，第二张紧件312包括位于第一下固定部232及第五滑轮325之间的第六段312a，以及位于第六滑轮326与第二上固定部233之间的第七段312b，优选的，第六段312a和第七段312b沿竖直方向延伸。
与第一张紧件311、第一滑轮321和第二滑轮322类似的，在第一滑动板23a沿竖直方向向上移动时，第六段312a伸长，第七段312b缩短，且第六段312a伸长的长度与第七段312b缩短的长度相同，进而使与第七段312b相固定的第二滑动板23b能够沿竖直方向位移与第一滑动板23a相同的长度。
可以理解的，为了避免第二张紧件312与搁物架装置其他组件发生干涉，同步组件3还包括第七滑轮327和第八滑轮328，进一步的，第二张紧件312一端固定于第一滑动板23a第一下固定部232，另一端通过第五滑轮325、第七滑轮327、第八滑轮328和第六滑轮326，固定于第二滑动板23b的第二上固定部233。
更具体的，第二张紧件312包括位于第五滑轮325与第七滑轮327之间第八段312c，位于第七滑轮327与第八滑轮328之间的第九段312d，以及位于第八滑轮328和第六滑轮326之间的第十段312e，优选的，第九段312d沿竖直方向延伸，第八段312c沿水平方向延伸。
在本实施方式中，第一张紧件311和第二张紧件312及对应的滑轮组共同组成了同步组件3，但是在实际移动过程中第三段311c和第十段312e若同样处于水平状态或与水平方向具有其他相同角度时，可能存在干涉，导致第一张紧件311与第二张紧件312之间发生相互摩擦进而导致磨损，因此第三段311c与第十段312e可以保持一定角度或距离，从而避免干涉，在本实施方式中，第三滑轮323位于第六滑轮326下方靠近第一滑动板23a一侧，第八滑轮328位于第一滑轮321下方靠近第二滑动板23b一侧，从而使第三段311c与第十段312e形成X形交叉结构，进一步减少第一张紧件311与第二张紧件312之间的干涉。可以理解的，将第三滑轮323和第八滑轮328分别固定于第六滑轮326和第一滑轮321下方的相应位置，同样能够实现上述技术效果。相对应的，在本实施方式中第七滑轮327固定于第五滑轮325靠近第二滑动板23b一侧，第四滑轮324固定于第二滑轮322靠近第一滑动板23a一侧。
当然，还存在其他实施方式，如将第三滑轮323固定于第六滑轮326下方远离第一滑动板23a一侧，第四滑轮324固定于第二滑轮322远离第一滑动板23a一侧，以及对应的，将第八滑轮328固定于第一滑轮321下方远离第二滑动板23b一侧，第七滑轮327固定于第五滑轮325远离第二滑动板23b一侧，或者将第三滑轮323和第八滑轮328分别固定于第六滑轮326和第一滑轮321上方的相应位置，从而使第三段311c与第十段312e形成X形交叉结构，均能实现上述预期技术效果。
在本实施方式中，滑轮设置于相应的轨道槽21上，更具体的，将上述第一滑轮321、第八滑轮328设置于第一滑动板23a上方的第一轨道槽21a表面，将第五滑轮325、第七滑轮327设置于第一滑动板23a下方的第一轨道槽21a表面，与此相对应的，将上述第六滑轮326、第三滑轮323以及第二滑轮322、第四滑轮324分别设置于第二滑动板23b上方和下方的第二轨道槽21b表面，如此不仅能够提高滑轮结构的稳定性，而且使得搁物架装置的安装和拆卸过程更为方便，避免对冰箱内壁造成损坏。
下面通过举例，说明在同步组件3作用下搁物架组件1和滑道组件2中滑动板23的同步运动情况，如图2和图5所示，当抬动搁架本体11，通过搁架本体11两侧的支架12及其挂钩，从而带动滚轮235和滑动板23，沿竖直方向向上位移第一长度L1时，第一滑动板23a上端固定的第一张紧件311的第一段311a同样缩短第一长度L1，并通过第三段311c、第四段311d和第五段311e的传动，使得第二段311b伸长第一长度L1，与此相对应的，通过搁物架组件1与第一滑动板23a相连的第二滑动板23b；同时，在向上位移第一长度L1时，第二张紧件312通过第七段312b、第十段312e、第九段312d和第八段312c的传动，使第六段312a同样伸长第一长度L1。也即，通过第一张紧件 311和第二张紧件312的交叉联动，对第一滑动板23a和第二滑动板23b进行牵制，进而使其上下位移长度相同。
进一步的，当滑动板23固定于轨道槽21内时，第一上固定部231、第一下固定部232和第二上固定部233、第二下固定部234，分别位于第一滑动板23a和第二滑动板23b上下端靠近轨道槽21一侧边沿的中心位置，从而使得滑动板23在上下移动过程中，不致因第一张紧件311和第二张紧件312的拉动失去自身平衡。
在本实施方式中，第一张紧件31和第二张紧件32配置为同步钢丝，钢丝具有结构强度高的、使用寿命长的特点，能够为滑动板23提供更好的拉力和同步效果。
如图6和图7，对于搁物架组件1在滑道组件2上的固定方式，主要通过搁物架组件1的支架12与滑道组件2内部止挡位22以及滚轮235的配合实现。
如图6所示，为可调搁物架装置的静止状态，支架12在竖直方向、远离搁架本体11支撑面一端设有第一支撑部121，第一支撑部121优选设计为L形把手结构，与轨道槽21内部设置的止挡位22中的第一配合部221限位固定，优选第一配合部221为一凹槽，该凹槽用以配合L形把手结构的上下端面，其横截面为L形。
进一步的，支架12沿竖直方向上，靠近搁架本体11支撑面一处设有第二支撑部122，第二支撑部122为一凸起，凸起具有相对竖直方向倾斜的斜面，该斜面与止挡位22中的第二配合部222具有自锁角度，该自锁角度能够提供未承重状态下的搁物架组件1，以使其不致与条状止挡部220发生相对运动的摩擦力，另一方面，该配合结构能够一定程度上减少第一支撑部121和第一配合部221的磨损。
在静止状态下，止挡位22中第一配合部221与支架12上第一支撑部121限位固定，此时其与第一支撑部121下端面存在面接触，同时第二支撑部122与第二配合部222自锁，在搁架本体11表面承重时，由于杠杆原理，第一支撑部121和第二支撑部122会分别给予第一配合部221和第二配合部222一个水平的、朝向止挡位22内部的压力，对应分别得到第一配合部221和第二配合部222分别提供的方向相反的支持力，此时由于支撑部与止挡位22之间的具有摩擦系数，接触部位摩擦力增大，进而使得搁物架装置整体结构稳定。
在静止状态下，若将搁架本体11向上抬起，搁物架组件1以支架12上所限位固定的，靠近搁架本体11支撑面一端的滚轮235为旋转轴旋转一定角度，即可将搁物架装置切换为移动状态，即如图7所示。
此时，第一支撑部121与第一配合部221脱离，第二支撑部122与第二配合部222脱离，进而解除限位和自锁结构，进一步将搁架本体11沿竖直方向托起或推下，与支 架12固定的滑动板23即可沿轨道槽21在竖直方向上下移动，移动过程中，固定于轨道槽21顶端的弹性组件26持续为滑动板23提供弹性恢复力，从而使得移动过程中用户只需克服轨道槽21内的滑动摩擦力即可调整搁物架组件1的位置。
相比于现有技术而言，在本实施方式中，由于同时布置有弹性组件26和同步组件3，在搁物架组件1调整位置过程中，能够持续为滑动板23提供拉力，从而能够实现搁架本体11两侧平衡的同时，保证即使在搁架本体11支撑面上存在重物的情况下，仍能够仅通过上下抬动和拉动等简便操作，即可实现搁物架组件1位置的调整。
应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施方式中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
上文所列出的一系列的详细说明仅仅是针对本发明的可行性实施方式的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施方式或变更均应包含在本发明的保护范围之内。
