Description

一种包装结构
本申请要求于2017年1月20日提交中国专利局、申请号为201710049665.5、发明名称为“电子膨胀阀的包装结构”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及产品包装技术领域，特别是涉及一种用于电子膨胀阀的包装结构。
背景技术
请参考图1，图1为现有技术中一种典型电子膨胀阀的结构示意图。
如图所示，电子膨胀阀100的外形大体呈丁字形结构，包括阀体101、设于阀体101上的外壳105，以及与阀体101连接的第一接管102、第二接管103，外壳105内设有磁转子104；其中，阀体101、外壳105、磁转子101及第一接管102同轴设置，第二接管103连接于阀体101的侧面，与阀体101轴线大体垂直设置。
另外，除上述结构外，还有部分电子膨胀阀100的第二接管会设为弯折结构，其中一部分管段的轴线仍与阀体101轴线垂直设置，另一部分折弯的管段大体与第一接管102平行。
通常，电子膨胀阀100在出厂时会将阀的开度调整到指定位置，在后续装配时无需重新开阀复位，这样就要求电子膨胀阀100的包装结构能够对阀进行很好的定位，以免运输过程中因振动导致阀的开度变化。
请一并结合图2，图2为现有技术中一种电子膨胀阀的包装结构的示意图。
如图所示，该包装结构为防尘帽部件200，其具有至少两个相连的防尘帽201；包装时，将与防尘帽201数目相同的电子膨胀阀100同向、并排放置，相邻两电子膨胀阀100通过外壳105内部的磁转子104相吸在一起，防尘帽部件200的各防尘帽201依次套在各电子膨胀阀100的接管上以固定电子膨胀阀100；由于电子膨胀阀100有两个接管，所以包装时每组电子膨胀阀100通过两个防尘帽部件200来包装固定；装箱时，将固定 好的各组电子膨胀阀100放入包装箱的各隔间内。
该种包装结构虽然能够很好地对电子膨胀阀100进行定位，但是由于包装时，需要将两个以上的电子膨胀阀100同向并排放置好后，才能套入防尘帽部件，包装时比较费力，应用时，需要同时拿取两个以上的电子膨胀阀100，非常不方便。
此外，对于在阀体101上外套线圈固定架106结构的电子膨胀阀100来说，如图1所示，上述防尘帽部件200则无法适用。
有鉴于此，如何改进现有电子膨胀阀的包装结构，以降低电子膨胀的包装难度，提高包装效率，且便于电子膨胀阀的拿取，是本领域技术人员目前需要解决的技术问题。

各支撑部301均具有交替排列的第一凹部311a和第二凹部311b，第一凹部311a和第二凹部311b均用于支撑电子膨胀阀100的外壳105；其中，相邻的第一凹部311a和第二凹部311b的中心距与电子膨胀阀100的外壳的外径相同。
各支撑部301的两侧均分设有第一卡置部302和第二卡置部303，以图3所示示图方位，第一卡置部302位于支撑部301的左侧，第二卡置部303位于支撑部301的右侧；其中，第一卡置部302具有多个第一卡槽321，分别与第一凹部311a的位置对应，第二卡置部303具有多个第二卡槽331， 分别与第二凹部311b的位置对应；第一卡槽321和第二卡槽331均用于卡置电子膨胀阀100的第一接管102，即与阀体101轴线重合的接管。
支撑部301与第一卡置部302之间具有用于容纳电子膨胀阀100的第二接管103的第一容纳空间，支撑部301与第二卡置部303之间具有用于容纳电子膨胀阀100的第二接管103的第二容纳空间305。
可以理解，当电子膨胀阀100的外壳105由第一凹部311a支撑时，其第一接管102卡置在与第一凹部311a位置对应的第一卡槽321内，其第二接管103容置在第一容纳空间；当电子膨胀100的外壳105由第二凹部311b支撑时，其第一接管102卡置在与第二凹部311b位置对应的第二卡槽331内，其第二接管103容置在第二容纳空间305。
需要说明的是，从结构来说，第一凹部311a和第二凹部311b、第一卡置部302的第一卡槽321和第二卡置部303的第二卡槽331，及第一容纳空间和第二容纳空间305的结构相同或相似，此处的“第一”和“第二”仅是为了描述技术方案的清楚及方便，不表示顺序，更不应理解为某种限定。
该包装结构在包装电子膨胀阀100时，相邻的两电子膨胀阀100水平相向放置，这里的水平指的是电子膨胀阀100的阀体101轴线呈水平状态放置，相向指的是两个电子膨胀阀100的朝向相反；如上包装结构的具体描述，由于卡置电子膨胀阀100的第一接管102的卡置部交替设于支撑部301的两侧，所以依次放置电子膨胀阀100后，相邻的电子膨胀阀100即为水平相向状态。
具体地，以相邻的两电子膨胀阀100在包装结构中的放置为例说明，其中一个电子膨胀阀100的外壳105由支撑部301的第一凹部311a支撑，第一接管102卡置在对应于该第一凹部311a的第一卡槽321内，这样，第二接管103就可置于支撑部301与第一卡置部302之间的第一容纳空间内，相应地，与该电子膨胀阀100相邻的另一个电子膨胀阀100的外壳105由与第一凹部311a相邻的第二凹部311b支撑，第一接管102则卡置在对应于该第二凹部311b的第二卡槽331内，这样，第二接管103就可置于支撑部301与第二卡置部303之间的第二容纳空间305内；由于相邻的第一凹部311a和第二凹部311b的中心距与电子膨胀阀100的外壳105的外径相 同，所以，如上放置后，相邻两电子膨胀阀100的两外壳105会紧密接触，同时依靠两者内部的磁转子104相互吸合而紧密贴合，这样，在运输过程中可以防止出现转子转动导致电子膨胀阀100的出厂开度发生变化。
装满电子膨胀阀100的包装结构的本体可参考图4理解，该实施例中，包装结构的本体300中容纳的是图5所示的电子膨胀阀100结构，即第二接管103为横接管的结构；图4中，电子膨胀阀100a放置于支撑部301的第一凹部311a及对应的第一卡槽321、第一容纳空间内，与其相邻的电子膨胀阀100b放置于支撑部301的第二凹部311b及对应的第二卡槽331、第二容纳空间305内。
如上，包装时，各电子膨胀阀100是相互独立的，只要将电子膨胀阀100的各部分对应放入包装结构中的相应部位即可，同样，拿取时单独拿取，不受其他阀件的影响，与现有技术中将两个以上电子膨胀阀100捆绑包装和拿取相比，本申请提供的包装结构使得电子膨胀阀100的包装和拿取更方便，效率更高。
另外，结合图4，电子膨胀阀100放置于包装结构的本体300中后，阀体101上固设的线圈固定架106位于支撑部301与卡置部之间的容纳空间内，且相邻的两电子膨胀阀100是水平相向设置，线圈固定架106的设置不会影响两电子膨胀阀100的外壳105的紧密接触，也就是说，线圈固定架106不会影响电子膨胀阀100的定位，该种包装结构可适用于具有线圈固定架106的电子膨胀阀100的包装运输。
如图3所示，本实施例提供的包装结构的本体300具有两组支撑部301、卡置部(包括第一卡置部302和第二卡置部303)和容纳空间(包括第一容纳空间和第二容纳空间305)，一个本体300能够放置较多的电子膨胀阀100。应当理解，实际设置时，根据需要，包装结构的本体300可以只具有一组支撑部301、卡置部和容纳空间，当然也可以具有更多组支撑部301、卡置部和容纳空间。
该实施例中，第一卡置部302的第一卡槽321用于卡置电子膨胀阀100的第一接管102，在实际设置时，可以使第一卡置部302与支撑部301之间的距离适当，以使电子膨胀阀100的外壳105置于支撑部301的第一凹部311a，第一接管102卡置于第一卡槽321时，电子膨胀阀100的阀体101 的端面与第一卡置部302朝向支撑部301的端面抵接，以起到对阀体101限位的作用。相应地，第二卡置部303与支撑部301之间也具有适当的距离，以使第二卡置部303朝向支撑部301的端面能够抵接阀体101的端面，以对阀体101限位。
另外，实际设置时，第一卡置部302的第一卡槽321和第二卡置部303的第二卡槽331也可用于卡置电子膨胀阀100的阀体101，显然，是将阀体101靠近第一接管102的端部卡置于卡槽内，以免与第二接管103造成干涉。
进一步地，在第一容纳空间的底部设有多个第一凹腔，分别与第一凹部311a位置对应，在第二容纳空间305的底部设有多个第二凹腔，分别与第二凹部311b位置对应，第一凹腔和第二凹腔用于对电子膨胀阀100的第二接管103进行限位。这样，电子膨胀阀100放置在本体300中后，除了与相邻的电子膨胀阀100因电磁力吸合在一起外，其第二接管103的位置也被限定，定位更可靠。
显然，第一凹腔和第二凹腔应当与第二接管103的结构相适配，即，若电子膨胀阀100的第二接管103为图5所示的直管形式，那么第一凹腔和第二凹腔均设为与第二接管103的端部适配的圆形凹腔，在放置电子膨胀阀100后，其第二接管103能够插入第一凹腔或第二凹腔以实现定位。若电子膨胀阀100的第二接管为弯管形式，那么第一凹腔和第二凹腔与弯折的第二接管适配，使得电子膨胀阀放置后，弯折的第二接管能够卡入第一凹腔或第二凹腔内，以实现限位。
具体的方案中，第一卡置部302和第二卡置部303的外侧，即远离对应的支撑部301的一侧，均具有用以抵接电子膨胀阀100的第一接管102的止挡部，以限制电子膨胀阀100在水平方向的移动。
具体地，该实施例中，以图3所示本体300的方位为基准，右边的支撑部301的第二卡置部303的外侧有本体300的纵向侧壁306，实际中，为简化本体300的结构和节省材料，可将该纵向侧壁306作为卡置在该第二卡置部303的电子膨胀阀100的第一接管102的止挡部；结合图4，右边的支撑部301的第一卡置部302的外侧有位于左边的支撑部301的第二卡置部303，为缩小空间，可将左边的支撑部301的第二卡置部303作为 卡置在右边的支撑部301的第一卡置部302的电子膨胀阀100的第一接管102的止挡部。
相应地，对于放置在左边的支撑部301的电子膨胀阀100而言，本体300左边的纵向侧壁306可作为卡置在左边的第一卡置部302的电子膨胀阀100的第一接管102的止挡部，靠近右边的第一卡置部302可作为卡置在左边的第二卡置部303的电子膨胀阀100的第一接管102的止挡部。
如上设置后，参考图4，电子膨胀阀100装满后，靠近中间的两列电子膨胀阀100的第一接管102大体共用本体300的同一空间，能够减小本体300的横向尺寸。
可以理解，若本体300设置有更多支撑部301及其相对应的结构时，止挡部的设置也可与上类似设置。
当本体300只设有一个支撑部301及其相对应的结构时，本体300的两个纵向侧壁形成上述止挡部，分别抵接支撑于同一支撑部301的朝向相反的两电子膨胀阀100的第一接管102。
当本体300设有两个以上的支撑部301时，止挡部还可以如下设置：本体300的两纵向侧壁306仍为靠近纵向侧壁306放置的电子膨胀阀100的第一接管102的止挡部；两个支撑部301之间具有两个卡接部，分别形成该两个支撑部301中一者的第一卡置部，另一者的第二卡置部，可以在该两个卡接部之间设置隔板，该隔板的两侧壁作为靠近其放置的电子膨胀阀100的第一接管102的止挡部。
与前述图4所示本体300相比，相当于拉大两个支撑部301之间的第一卡置部302和第二卡置部303之间的距离，在两者之间设置用于止挡的隔板。
具体的方案中，本体300可以为纸浆模制品，也可以为吸塑板制品，参考图3，具体设置时，可以在本体300的纵向侧壁306上设置若干竖向延伸的筋部361，以提高本体300的强度；其中，筋部361的数量和排布可根据需要来设置，只要不影响电子膨胀阀100的放置即可。
具体的方案中，包装结构除了上述本体300外，还设有盖板400，以封堵本体300的开口，本体300装满电子膨胀阀100后可以盖上盖板400，如图6所示，这样，方便在外包装箱内放置多层包装结构，盖板400可以 看做是本体300与本体300之间的分隔。
具体的方案中，包装结构还包括多个防尘盖500，用于套装在电子膨胀阀100的第一接管102和第二接管103的管口，以防止灰尘或杂物进入阀内部。显然，各防尘盖500相互独立，以避免各电子膨胀阀100的包装相互干扰。
具体的方案中，包装结构还包括保护薄膜，用包裹放置于本体300内的所有电子膨胀阀100。具体操作时，先将保护薄膜放置于空的本体300的凹槽内，再依次装入电子膨胀阀100，装满后，再将保护薄膜折叠以完全包裹电子膨胀阀100，这样，能够起到防尘、防潮的作用。
具体地，保护薄膜可以设为塑料薄膜，以防止在折叠包裹时破损。
请参考图7，图7为本发明所提供包装结构的本体的第二实施例的结构示意图。
该实施例中，包装结构的本体300’也设有两个支撑部301’，同样地，该两个支撑部301’平行且间隔预定距离设置。
各支撑部301’均具有交替排列的第一凹部311a’和第二凹部311b’，第一凹部311a’和第二凹部311b’均用于支撑电子膨胀阀100的外壳105；其中，相邻的第一凹部311a’和第二凹部311b’的中心距与电子膨胀阀100的外壳的外径相同。
各支撑部301’的两侧分设有第一容纳部和第二容纳部，其中，第一容纳部具有多个第一容纳位302a’，分别与各第一凹部311a’的位置对应，第一容纳位302a’用于容置由第一凹部311a’支撑的电子膨胀阀100的除外壳105外的其他主要结构，如阀体101、第一接管102和第二接管103。
类似地，第二容纳部具有多个第二容纳位302b’，分别与各第二凹部311b’的位置对应，第二容纳位302b’用于容置由第二凹部311b’支撑的电子膨胀阀100的除外壳105外的其他主要结构，如阀体101、第一接管102和第二接管103。
具体的方案中，第一容纳位302a’和第二容纳位302b’均包括放置阀体101的阀体容置部、放置第一接管102的第一接管容置部322’及放置第二接管103的第二接管容置部323’。
其中，第一接管容置部322’呈台阶状结构，包括靠近阀体容置部的高 台阶面3221’和远离阀体容置部的低台阶面3222’，这样设计，方便第一接管102的管口套设防尘盖500后，能够被平稳地支撑；可以理解，第一接管102的管口套设防尘盖500后，防尘盖500部位的尺寸大于第一接管102主体的尺寸，这样，高台阶面3221’可以用于支撑第一接管102靠近阀体101的部分，防尘盖500由低台阶面3222’支撑，能够提高电子膨胀阀100在包装结构内的稳定性和安全性。
具体地，第二接管容置部323’可以设为斜面结构，这样设计，有助于降低本体300’的整体高度，在相同包装数量下能够降低包装箱的整体高度。
具体的方案中，在第一容纳位302a’的阀体容置部与对应的第一凹部311a’之间设有容置槽303’，用以嵌置对应位置的电子膨胀阀100的线圈固定架106；同样地，在第二容纳位302b’的阀体容置部与对应的第二凹部311b’之间也设有容置槽303’，用以嵌置对应位置的电子膨胀阀100的线圈固定架106。
如上设置后，电子膨胀阀100放置后，线圈固定架106卡嵌在容置槽303’内，能够防止电子膨胀阀100沿轴线方向来回移动，磨损阀体结构。
具体地，该容置槽303’还具有与线圈固定架106的外周贴合的弧形槽段，这样可以防止电子膨胀阀100的阀体101相对转动，避免损伤阀结构。
具体的方案中，该包装结构用于包装如图10所示的电子膨胀阀100时，在第一容纳位302a’和第二容纳位302b’均设有隔挡件，该电子膨胀阀100的第二接管103为弯管结构，包括横管段和竖管段。
其中，放置电子膨胀阀100后，该隔挡件能够将第一接管102和第二接管103的竖管段隔开，隔挡件的设置能够对电子膨胀阀100起到限位的作用，防止电子膨胀阀100在包装结构内晃动。
具体的方案中，在第一容纳位302a’和第二容纳位302b’远离支撑部301’的一侧均设有抵接第一接管102的止挡部。
该实施例中，以图7所示本体300’的方位为基准，前侧支撑部301’的第一容纳位302a’的前侧为本体300’的纵向侧壁，实际中，为简化结构和节省材料，该纵向侧壁可作为放置在该第一容纳位302a’的电子膨胀阀100的第一接管102的止挡部；前侧支撑部301’的第二容纳位302b’的后侧设置有止挡部，以抵接放置在该第二容纳位302b’的电子膨胀阀100的第一 接管102，该止挡部具体为靠近后侧的多个与第二容纳位302b’对应的隔挡柱305’。
需要特别指出的是，该实施例中，为简化结构，靠近后侧的一排隔挡柱305’还作为后侧支撑部301’的第一容纳位302a’的隔挡件。
如图7所述，该实施例中，前侧支撑部301’的第一容纳位302a’的隔挡件具体为隔挡板304’，该隔挡板304’具体与前侧的纵向侧壁固接；从图7所示看，可以理解，隔挡板304’的设置相当于将第一容纳部分隔为多个相对独立的腔室，位于两端部的腔室内分别容纳的是对应位置的电子膨胀阀100的第一接管102和第二接管103，其余腔室内容纳的是对应位置的电子膨胀阀100的第一接管102和相邻位置电子膨胀阀100的第二接管103。
应当理解，上述隔挡板304’实际上也可以用隔挡柱来替代，相较而言隔挡板304’的板状结构能够增强本体300’整体的强度。
对于后侧的支撑部301’而言，其具体结构与上述类似，不再赘述。
具体的方案中，本体300’可以为纸浆模制品，也可以为吸塑板制品。
具体设置时，可以在本体300’的相对两侧壁上设置内凹台阶306’，具体地，两侧壁上的内凹台阶306’非对称设置，图7所示方案中，相对的两侧壁中，一者上设有一个内凹台阶306’，另一者上设有两个内凹台阶306’。
实际中，包装时，各本体300’叠置后放入外包装箱内，如上设计后，在叠置本体300’时，可以使一个本体300’的设有一个内凹台阶306’的侧壁与其相邻的一本体300’的设有两个内凹台阶306’的侧壁位于同一侧，这样，叠置后，相邻两本体300’的同侧的内凹台阶306’交错，方便拿取和搬运。
需要说明的是，前述第一实施例的本体300结构也可在侧壁上设置类似结构，以达到相同的效果；同样地，该实施例提供的包装结构也可设置盖板以封堵本体300’的开口，也可设置保护薄膜以包裹电子膨胀阀100。
请参考图8和图9，图8为本发明所提供包装结构的本体的第三实施例的结构示意图；图9为图8所示本体装满电子膨胀阀的结构示意图。
该实施例中，包装结构的本体300”也设有两个支撑部301”，同样地，该两个支撑部301”平行且间隔预定距离设置。
各支撑部301”均具有交替排列的第一凹部311a”和第二凹部311b”， 第一凹部311a”和第二凹部311b”均用于支撑电子膨胀阀100的外壳105；其中，相邻的第一凹部311a”和第二凹部311b”的中心距与电子膨胀阀100的外壳的外径相同。
各支撑部301”的两侧分设有第一容纳部和第二容纳部，其中，第一容纳部具有多个第一容纳位302a”，分别与各第一凹部311a”的位置对应，第一容纳位302a”用于容置由第一凹部311a”支撑的电子膨胀阀100的除外壳105外的其他主要结构，如阀体101、第一接管102和第二接管103。
类似地，第二容纳部具有多个第二容纳位302b”，分别与各第二凹部311b”的位置对应，第二容纳位302b”用于容置由第二凹部311b”支撑的电子膨胀阀100的除外壳105外的其他主要结构，如阀体101、第一接管102和第二接管103。
具体的方案中，第一容纳位302a”和第二容纳位302b”均包括支撑电子膨胀阀100的阀体101的阀体平面部321”，支撑电子膨胀阀100的第一接管102的接管平面部322”，以及支撑第二接管103的接管斜面部323”。
如上，将支撑第二接管103的部位设为斜面结构，能够降低本体300”的整体高度。
具体的方案中，第一容纳位302a”的阀体平面部321”与第一凹部311a”之间具有嵌置电子膨胀阀100的线圈固定架106的容置槽303”，第二容纳位302b”的阀体平面部321”与第二凹部311b”之间也具有嵌置电子膨胀阀100的线圈固定架106的容置槽303”。
这样，电子膨胀阀100放置后，线圈固定架106卡嵌在容置槽303”内，能够防止电子膨胀阀100在本体300’内动作，提高包装的可靠性和稳定性。
具体的方案中，本体300”可以为纸浆模制品，也可以为吸塑板制品。
如图所示，具体设置时，在本体300”的中部设有支撑台304”，在包装后，各本体300”叠置后，该支撑台304”能够起到一定的支撑作用，提高本体300”整体的强度；更具体地，还可在该支撑台304”的两侧设置多个支撑柱305”，以进一步提高本体300”的承重能力。
实际设置时，支撑台304”两侧的支撑柱305”可以非对称设计，叠置本体300”时，相邻两本体300”的侧边反向对应，也就是说，一本体300” 叠放时，相对其相邻的本体300”水平旋转180度，这样，相邻的两本体300”的支撑柱305”位置不会对应，相当于增加了支撑点，起到很好的撑重作用。
与前述第二实施例类似，也可以在本体300”的相对两侧壁上设置非对称布置的内凹台阶306”，同样地，该实施例中的包装结构也可设置盖板、保护薄膜等结构，这里不再赘述。
需要进行说明的是，以上实施例以一种具体的电子膨胀阀结构为例进行了说明，而本发明所记载的所有实施例，并不局限于某一种具体的电子膨胀阀，本领域技术人员可以理解，所有具有类似外观构造的各类电动阀，只要其内部设置有磁转子，且具有保持出厂开度要求，均可以采用本发明所提供的包装结构。即，本说明书中所述的电子膨胀阀是一个广义的概念，本说明书所记载的实施例主要是对包装结构进行说明，无法穷举也无必要穷举所有的电子膨胀阀内部构造。
以上对本发明所提供的用于电子膨胀阀的包装结构进行了详细介绍。本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。
