组合式塑胶栈板 技术领域
本发明涉及仓储物流设备技术领域，尤其涉及一种组合式塑胶栈板。
背景技术
栈板是为方便零散物品的摆放和出货要求而制成的底座，放置在地面上可以避免物品受潮或受损，也可以与叉车、货架等物流设备配套作为物流单元使用，以便于货物装卸和搬运，是现代化物流仓储中必不可少的物流设备之一。目前，常用的栈板主要有木制栈板和塑胶栈板，其中，塑胶栈板因其质轻、耐腐蚀和使用寿命长等特点被广泛应用。但是，塑胶栈板通常采用注塑的方式一体成型，需要用很大的机器才能生产，而且多种类型的卡板需要做多套大型的模具，此外，材质多为塑料，容易变形，承重能力不强，卡板脚局部损坏则整个栈板无法正常使用，降低了使用寿命，使得生产成本较高。
发明内容
本发明针对上述问题，提出了一种可以根据需要自由组装且承重能力强的组合式塑胶栈板。

可选地，所述组合式塑胶栈板还包括若干底铺板，若干所述支撑脚沿第一水平方向和第二水平方向成排设置，若干底铺板沿第一水平方向和/或第二水平方向可拆卸地设置于所述支撑脚的底部。
可选地，所述底铺板的内部嵌有金属加强件，增加底铺板的结构强度，使得上货架时的结构牢靠。金属加强件为钢管。
可选地，所述支撑脚的底部设有横截面为圆形的卡柱，所述卡柱设有若干沿其圆周方向排布的第四卡脚，所述底铺板设有若干与所述第四卡脚相对应的卡槽，所述第四卡脚和所述卡槽配合卡定。
可选地，所述金属加强件包括管状的金属加强管以及内嵌于所述金属加强管内的支撑件，所述支撑件侧部抵顶在所述金属加强管的内壁上。
可选地，所述金属加强管的横截面为矩形，所述支撑件包括至少一个第一支撑部以及至少一个第二支撑部，所述第一支撑部和所述第二支撑部相互垂直设置。
可选地，所述金属加强管套设有若干定位扣件，所述定位扣件外侧面部分向外凸起形成定位部。
可选地，所述面板上和/或面板的边沿设有应力释放区。该应力释放区可以为圆孔或者圆弧槽，可以防止面板注塑成型后应力集中。
具体地，面板的边沿设有圆弧槽，圆弧槽的数量可以为双数个，双数个圆弧槽在面板的边沿对称设置，可以均匀地降低应力集中，避免面板不 均匀变形。其中，圆弧槽为圆形弧状或椭圆弧状，该圆弧槽也可以是和圆弧和圆孔组合的结构。面板上设有圆孔，圆孔可以是圆形或者椭圆形，具体根据面板的受力方向和位置选择开孔部位，圆形孔一般应开在低应力区，如果必须开在高应力区，则采取椭圆形孔，椭圆形的长轴与主应力方向平行，可以有效降低应力集中系数。
本发明的有益效果是：本发明提供的组合式塑胶栈板，面板和支撑脚之间为可拆卸结构，可以对支撑脚和面板进行随意组装，可以满足不同的存储需求，且支撑脚损坏时只需要更换支撑脚即可，不需要对整个塑胶栈板进行更换，节省了资源和维护成本。塑胶栈板的各部分可以分开生产制造，当需要生产不同类型的卡板时，调整其中的某个或几个模具即可，注塑设备和模具的通用性更高，可以有效降低生产成本。面板的内部镶嵌有金属加强件，可以有效地增强面板的结构强度，保证面板的使用寿命，此外由于金属加强件是在面板注塑时内嵌于面板内部的，可以有效地避免金属加强件氧化腐蚀的问题。支撑脚的侧面向内设置有第一凹槽，支撑脚的侧边向外凸形成有加强棱，即支撑脚的侧面为曲折的结构，支撑脚的结构强度高、支撑结构更稳定。

具体实施方式
下面结合各附图，通过具体实施例，对本发明进行详细、完整的描述。
请参考图1-13所示，本发明提供一种组合式塑胶栈板，包括面板1以及若干可拆卸地设置于面板1的下侧面的支撑脚2，面板1的内部嵌有金属加强件3，每个支撑脚2均为长方体，每个支撑脚2的四个侧面均向内凹陷形成有第一凹槽21，每个支撑脚2的四个侧边形成有加强棱22，加强棱22与第一凹槽21的槽底通过圆弧顺滑过渡。
面板1和支撑脚2之间为可拆卸结构，可以对支撑脚2和面板1进行随意组装，可以满足不同的存储需求，且支撑脚2损坏时只需要更换支撑脚2即可，不需要对整个塑胶栈板进行更换，节省了资源和维护成本。塑胶栈板的各部分可以分开生产制造，当需要生产不同类型的卡板时，调整其中的某个或几个模具即可，注塑设备和模具的通用性更高，可以有效降 低生产成本。面板1的内部镶嵌有金属加强件3，可以有效地增强面板1的结构强度，保证面板1的使用寿命，此外由于金属加强件3是在面板1注塑时内嵌于面板1内部的，可以有效地避免金属加强件3氧化腐蚀的问题。支撑脚2的侧面向内设置有第一凹槽21，支撑脚2的侧边向外凸形成有加强棱22，即支撑脚2的侧面为曲折的结构，支撑脚2的结构强度高、支撑结构更稳定。
面板1为矩形面板，通过在面板1的下侧面安装的支撑脚2的数量不同可以相应的组装成四脚、五脚、六脚、八脚、九脚的塑胶栈板，以满足不同货物的存储需求。例如，请参考图3所示，当在面板1的四个角处分别设置有一个支撑脚2时，可以组装形成四脚塑胶栈板；请参考图4所示，当在面板1的四个角处分别设置有一个支撑脚2，且在面板1的中部设置有一个支撑脚2时，可以组装形成五脚塑胶栈板；请参考图5所示，当在面板1的两个长侧边分别设置有三个支撑脚2时，可以组装形成六脚塑胶栈板；当在面板1的四个角处和四个侧边处分别设置有一个支撑脚2，可以组装形成八脚塑胶栈板(图中未示出)；请参考图6所示，当在面板1的四个角处、四个侧边以及面板1的中部分别设置有一个支撑脚2，可以组装形成九脚塑胶栈板。
其中，金属加强件3呈目字型或田字型或日字型或口字型，多种不同类型的框架可以更好的适应塑胶栈板的使用要求。
一实施例中，请参考图1和图9所示，面板1的上侧面的边沿设有若干挡块4，挡块4与第一凹槽21相对应设置。一方面，挡块4设置于面板1的边沿且凸出于面板1，使得货物放置于面板1上时，挡块4对货物具有限位的作用，防止搬运时或者倾斜时货物滑落；另一方面，塑胶栈板之间堆叠时，挡块4可以插入第一凹槽21内，使得成堆堆叠的塑胶栈板的结构稳定、可靠。具体地，挡块4具有导入斜面41，以便挡块4卡入第一凹槽21内。
一实施例中，请参考图1、图7和图13所示，面板1的上侧面还设有若干用于防滑的防滑块5，防滑块5设有防滑凸纹51。在面板1上设置防滑块5，可以增加面板1和货物之间的摩擦阻力，防止搬运时或者倾斜时 货物滑动。具体地，防滑纹可以是矩形圈纹理或者其他结构的矩形纹理，对货物在四个方向上均具有防滑的作用。
一实施例中，请参考图9和图10所示，挡块4和面板1之间通过第一卡接结构6可拆卸地连接，第一卡接结构6包括第一卡位槽61、第一卡脚62以及第二卡脚63，第一卡脚62和第二卡脚63相互间隔，且第一卡脚62和第二卡脚63的朝向相背设置，第一卡脚62和第二卡脚63伸入第一卡位槽61内相配合卡定。第一卡脚62和第二卡脚63的朝向相背，使得挡块4和防滑块5卡入面板1的第一卡位槽61内时，两侧均能够很好地卡定，结构稳定，挡块4和防滑块5均不会晃动。此外，第一卡脚62和第二卡脚63相互之间有间隔，使得第一卡脚62和第二卡脚63的弹性变形空间相对更大，且不会相互干扰。第一卡脚62和第二卡脚63均设置有辅助卡入第一卡位槽61内的斜面设计以及用于与第一卡位槽61的槽壁配合卡定的台阶。
其中，防滑块5和面板1之间也可以采用第一卡接结构6连接。
具体地，第一卡脚62和第二卡脚63可以设置于挡块4和防滑块5上，第一卡位槽61设置于面板1上；但不限于此，第一卡脚62和第二卡脚63也可以是设置在面板1上，第一卡位槽61设置于支撑脚2上，均可以实现面板1和挡块4、防滑块5之间的卡接连接，本发明对此不作具体限定。
一实施例中，请参考图2、图9和图10所示，面板1和支撑脚2通过第二卡接结构7可拆卸地连接，第二卡接结构7包括第三卡脚71、卡位柱72以及第二卡位槽73，第三卡脚71具有卡位台阶711和卡入头部712，且卡位台阶711与卡位柱72配合限位，卡入头部712具有卡入斜面713，卡入头部712的部分插入第二卡位槽73内，使得第三卡脚71和第二卡位槽73之间可以在水平方向上形成限位结构，卡入头部712设置的卡入斜面713设置使得卡入头部712无法完全伸入第二卡位槽73内，再配合卡位台阶711和卡位柱72的限位结构，能够在竖直方向上形成限位结构，进而保证面板1和支撑脚2之间形成的第二卡接结构7稳定。同时，卡入斜面713的设计，使得第三卡脚71卡入时更为顺畅。第三卡脚71的背面可以设置有加强筋714，使得第三卡脚71具有较高的结构强度，加强筋 714上的斜面设计也可以限制第三卡脚71伸入第二卡位槽73的深度。具体地，第三卡脚71可以设置于支撑脚2上，卡位柱72和第二卡位槽73相对应于第三卡脚71设置于面板1上；但不限于此，第三卡脚71也可以是设置在面板1上，卡位柱72和第二卡位槽73相对应于第三卡脚71设置于支撑脚2上，均可以实现面板1和支撑脚2的卡接连接，本发明对此不作具体限定。
一实施例中，请参考图7和图8所示，组合式塑胶栈板还包括若干底铺板8，若干支撑脚2沿第一水平方向X和第二水平方向Y成排设置，若干底铺板8沿第一水平方向X和/或第二水平方向Y可拆卸地设置于支撑脚2的底部。
请参考图16所示，底铺板8的内部嵌有金属加强件3，可以增加底铺板8的结构强度，使得上货架时的结构牢靠。金属加强件3为钢管，钢管沿底铺板8的长度方向布设。底铺板8的边沿也设置有圆弧槽和圆孔的组合，防止注塑成型后底铺板8的应力集中。
具体地，支撑脚2的数量可以为九个，九个支撑脚2排列成3x3的结构，请参考图7所示，所有的底铺板8均沿第一水平方向或者沿第二水平方向排布时可以形成川字结构的塑胶栈板；请参考图8所示，所有的底铺板8沿第一水平方向和第二水平方向排布时可以形成田字形结构的塑胶栈板。
但不限于此，请参考图5和图6所示，支撑脚2的底部也可以只设置有与其底部形状相适应的底脚板9，使得支撑脚2可以根据需要调整成单个支脚、川字或者田字结构，支撑脚2和底脚板9、底铺板8之间不同的组合方式可以涵盖所需的所有非套叠类型的栈板。请参考图17所示，底脚板9的底面设有安装孔91，用于安装防滑垫。防滑垫为硅胶或橡胶等软质材料的，可以增加底脚板9和地面之间或者叠放时底脚板9和与其接触的面板1之间的摩擦作用。
其中，底铺板8的两侧具有朝向地面向下倾斜的倾斜面，以便叉车插入。
一实施例中，请参考图9和图10所示，支撑脚2的底部设有横截面 为圆形的卡柱23，卡柱23设有若干沿其圆周方向排布的第四卡脚231，底铺板8设有若干与第四卡脚231相对应的卡槽81，第四卡脚231和卡槽81配合卡定。第四卡脚231和卡槽81均呈弧形，所有的第四卡脚231围成圆形结构，所有的第四卡脚231和其对应的卡槽81配合卡定的结构稳定，不容易晃动。所有的第四卡脚231的朝向可以是相同的，也可以是不同的，本发明实施例对此不作具体限定。
卡柱23可以是贯穿于支撑脚2设置的，即支撑脚2的两端可以都设置有卡柱23的结构，面板1上设有定位筒11，支撑脚2上端的卡柱23套入或者插入面板1的定位筒11，支撑脚2下端的卡柱23和底铺板8配合卡定。
但不限于此，请参考图18所示，卡柱23的横截面也可以为十字形或X字的交叉结构，十字形或X字形的卡柱23插入面板1的定位筒11内。其中，卡柱23的尺寸略大于定位筒11的内径，卡柱23和定位筒11之间的装配结构稳定，由于卡柱23和面板1的接触面积小，更容易将卡柱23插入。卡柱23的插入端设置有导入面，以便卡柱23能够顺畅地插入定位筒11内。
此外，支撑脚2和底脚板9之间也可以通过上述的第四卡脚231和卡槽81配合可拆卸地连接。
一实施例中，请参考图11和图12所示，金属加强件3包括管状的金属加强管31以及内嵌于金属加强管31内的支撑件32，支撑件32侧部抵顶在金属加强管31的内壁上。金属加强管31使用中空管状，可以在保持主体加强框架强度和刚性的同时，大幅度减少重量，节省材料，节约成本。
金属加强管31的横截面为矩形，支撑件32包括至少一个第一支撑部321以及至少一个第二支撑部322，第一支撑部321和第二支撑部322相互垂直设置，使得支撑件32的横截面为卄字型、十字型或者井字形结构，可以防止中空的金属加强管31在注塑压力下挤压变形，在金属加强管31的内部嵌入支撑件32在增强金属加强件3的强度和刚性的同时，又不会显著地增加金属加强件3的重量。
金属加强管31套设有若干定位扣件33，定位扣件33外侧面部分向外 凸起形成定位部331。定位扣件33优选使用卡扣的方式套设在主体加强框架上，结构简单，安装方便，也可以使用螺栓等其他可拆卸的连接方式。定位扣件33优选使用塑料制成。
在制造塑料品时进行注塑成型前，先把金属加强件3植入到模具预留的位置中，将定位扣件33扣接到模具内对应的卡扣部位，从而将金属加强件3相对模具固定，防止金属加强件3在随后的模具移动和注塑成型中相对模具出现错位，而且定位扣件33在注塑成型时可以将包裹金属加强件3的塑料分割成段，避免由于塑料注塑成型后，包裹的塑料发生收缩时被金属加强件3冲破、开裂。在面板1注塑时同步植入金属加强件3，金属加强件3在注塑成型时可以被塑料全覆盖，面板1的整体性更好，结构强度高。
在定位扣件33的一侧面开设断口槽332，使得定位扣件33可以从金属加强管31的中间部位直接卡扣进去，使用更为方便。
请参考图14和15所示，一实施例中，面板1上设有圆孔12，面板1的边缘设有圆弧槽13和圆孔的组合，防止注塑成型后面板1的应力集中。其中，面板1为矩形结构，面板1的四个边分别均匀设置有两个圆弧槽13，面板1内均匀设置有四个圆孔12，使得应力均匀化。
以上仅为本发明的优选实施例，并非因此即限制本发明的专利保护范围，凡是运用本发明说明书及附图内容所作的等效结构变换，直接或间接运用在其他相关的技术领域，均同理包括在本发明的保护范围内。
