Description

可折叠跳板 技术领域
本发明涉及一种跳板，尤其是一种可折叠跳板。
背景技术
目前跳板多用于车辆的装载或者维修时的抬高，但是由于跳板长度太长，不方便保管储存，所以后来陆续使用可折叠的跳板，来减少占用空间和搬运空间。
有时跳板一端通常安装一个斜板用于轮胎爬坡，而为了轮胎止动，会在跳板上安装一个挡件，当车轮行进至挡件处时，即行进到位。
现有折叠跳板虽能实现折叠功能，除了相连的各个节板外的其他部件只能拆卸另放，费时费力还易丢，当需要使用时还需要通过螺栓固定至节板上，拆装费时费力。
发明内容
针对现有技术中存在的不足，本发明提供一种可折叠跳板，采用转动连接的斜板，并且翻转后直接隐藏在跳板内，操作省时省力，防止丢失。
本发明采用的技术方案是：一种可折叠跳板，包括第一节板、第二节板、斜板；
所述第一节板的一端通过转接件转动连接第二节板的一端；所述转接件具有设定高度，以使得第一节板向第二节板翻转折叠后在两者之间具有容置空间；
所述斜板的一端转动连接在第一节板的另一端；所述斜板能够向第一节板背面方向翻转，且所述容置空间能够容纳翻转折叠后的斜板。
进一步地，所述斜板的一端连有用于限制转角的搭边。
进一步地，还包括挡件；所述挡件底部设有快拆连接件，所述第一节板背离斜板的一端正面设有与快拆连接件适配的快拆固定部。
进一步地，挡件底部的快拆连接件为卡钉；第一节板一端正面的快拆固定部为第一卡孔。
进一步地，所述第一卡孔包括相通的导入孔部和定位孔部；第一卡孔的定位孔部的横向尺寸小于其导入孔部，且第一卡孔的定位孔部相对于其导入孔部位于第一卡孔背离斜板的一侧。
进一步地，所述容置空间位于背离斜板的一端设有用于存放挡件的挡件容置部。
进一步地，在挡件容置部，第二节板的一端背面设有与挡件的快拆连接件适配的快拆固定部。
进一步地，第二节板一端背面的快拆固定部为第二卡孔；所述第二卡孔包括相通的导入孔部和定位孔部；第二卡孔的定位孔部的横向尺寸小于其导入孔部，且第二卡孔的导入孔部相对于其定位孔部位于第二卡孔背离斜板的一侧。
进一步地，所述挡件底部设有向其背面凸出的弹性件。
进一步地，还包括第三节板；所述第三节板的一端与第二节板的另一端转动连接，第三节板的长度小于第二节板，以使得第三节板向第二节板背面方向翻转折叠后，在容置空间背离斜板的一端留有挡件容置部。
进一步地，还包括挂臂，挂臂的一端与第二节板的侧面转动连接，挂臂另一端为活动端且设有挂孔，第一节板和/或第二节板侧面设有与挂臂挂孔适配的挂钉。
本发明的优点：
转接的斜板与第一节板始终相连，翻转后隐藏在容置空间内，不占用外部空间，不需要反复拆装，无需单独拿取和存放；
斜板另一端设搭边，使得斜板转过一定角度后，搭边直接与第一节板搭接，不需要额外配置固定件来固定斜板的位置，结构简单稳定，而且搭边不影响车轮行进，使得空间布置更加合理；
采用快拆式的挡件代替螺栓固定式的挡件，减少拆装所耗时间，另外不使用时挡件可以快速固定在容置空间的容置部内，无需单独拿取和存放，以免挡件丢失；
弹性件提供弹力，使得挡件与接触面件始终处于弹性支撑状态，挡件和与其相连的第一节板或第二节板静摩擦力增加，挡件不易脱落。

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，以下结合附图及实施例，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。
本发明提供一种可折叠跳板，包括第一节板1、第二节板2、第三节板3、斜板4、挡件5以及挂臂6。
请参阅附图1，所述第一节板1的一端通过转接件转动连接第二节板2的一端；所述转接件具有设定高度，以使得第一节板1向第二节板2翻转折叠后在两者之间具有容置空间；具体地，转接件包括分别连接于第一节板1一端和第二节板2一端的成对设置的延伸板7、8，两块延伸板7、8分别铆接或焊接于第一节板1一端和第二节板2一端，延伸板7、8也可以与第一节板1或第二节板2一体构造；两块延伸板7、8之间通过螺栓螺母转动连接。
所述斜板4的一端转动连接在第一节板1的另一端；所述斜板4能够向第一节板1背面方向翻转，且所述容置空间能够容纳翻转折叠后的斜板4；具体地，斜板4与第一节板1之间可以通过转轴、销轴、螺栓螺母或其他能够实现旋转的零部件连接；或者，直接在斜板4内侧设两个内凸的凸起，在第一节板1外侧设与凸起对应的凹槽、销孔或连接孔，同样能够实现斜板4的转动，从而当不需要使用斜板4时，斜板4可以直接翻转隐藏在容置空间内且不占用外部空间，方便收纳且不会丢失。
作为本发明的一个实施例，所述斜板4的一端连有用于限制转角的搭边401；其中搭边可以与斜板4一体成型，也可以通过其他如焊接、铆接、螺栓固定等安装方式固定在斜板4上；当斜板4转过一定角度后，搭边401搭载于第一节板1上的边缘位置；另外，为了提高搭边401的强度，减少变形量，还可以在搭边401和斜板4之间设一条加强板。
请参阅附图2-4，所述挡件5底部设有快拆连接件，所述第一节板1背离斜板4的一端正面设有与快拆连接件适配的快拆固定部；
作为本发明的一个实施例，挡件5底部的快拆连接件为卡钉501；第一节板1一端正面的快拆固定部为第一卡孔9；所述第一卡孔9包括相通的导入孔部901和定位孔部902；第一卡孔9的定位孔部902的横向尺寸小于其导入孔部901，且第一卡孔9的定位孔部902相对于其导入孔部901位于第一卡孔9背离斜板4的一侧；具体地，将卡钉501插入第一卡孔9的导入孔部901后滑向第一卡孔9的定位孔部902，由于第一卡孔9的定位孔部902的横向尺寸小于其导入孔部901，从而卡钉501无法从第一卡孔9的定位孔部902中拔出，当车轮来时与挡件5接触后，在卡钉501的限位下，挡件5始终与第一节板1卡接，挡件5不使用 时也可以快速拆卸。
请参阅附图5-6,所述容置空间位于背离斜板4的一端设有用于存放挡件5的挡件容置部；在挡件容置部，第二节板2的一端背面设有与挡件5的快拆连接件适配的快拆固定部；在挡件5不使用时，可以将挡件5隐藏在挡件容置部内，即不用单独存放和运输挡件5；
作为本发明的一个实施例，第二节板2一端背面的快拆固定部为第二卡孔10；所述第二卡孔10包括相通的导入孔部1001和定位孔部1002；第二卡孔10的定位孔部1002的横向尺寸小于其导入孔部1001，且第二卡孔10的导入孔部1001相对于其定位孔部1002位于第二卡孔10背离斜板4的一侧；具体地，挡件5从第一卡孔9内拆除后，将卡钉501插入第二卡孔10上的导入孔部1001后滑向第二卡孔10上的定位孔部1002，由于第二卡孔10的定位孔部1002的横向尺寸小于第二卡孔10的导入孔部1001，故卡钉501无法从第二卡孔10的定位孔部1002中拔出，当整个跳板被提起时，卡钉501始终卡在第二卡孔10的定位孔部1002，保持挡件5与第二节板2处于衔接的状态；
在本发明中，卡钉501、第一卡孔9和第二卡孔10的数量相等，且至少为两个，其中卡钉501可以制成与挡件5一体的结构，也可以与挡件5螺接，还可以采用焊接或销钉固定等方式连接；另外，第一卡孔9上的导入孔部901和定位孔部902、第二卡孔10上的导入孔部1001和定位孔部1002的形状可以为圆形或长圆形；
作为本发明的一个实施例，在第二节板2背面的挡件容置部铺设一块支撑板11，第二卡孔10设在支撑板11上，以此防止第二卡孔10对第二节板2造成影响或者破坏，支撑板11损坏也容易更换。
请参阅附图2，作为本发明的另一个实施例，所述挡件5底部设有向其背面凸出的弹性件502；弹性件502与卡钉501同侧，并且在卡钉501卡入第一卡孔9或者第二卡孔10内时，弹性件502与第一节板1或第二节板2或支撑板11接触并产生弹性形变，使得卡钉501与第一节1板或第二节板2或支撑板11之间的静摩擦力更大，松脱概率更低；
具体地，弹性件502为弧状的弹簧片。
请参阅附图7，所述第三节板3的一端与第二节板2的另一端转动连接，第三节板3的长度小于第二节板2，以使得第三节板3向第二节板2背面方向翻转折叠后，在容置空间背离斜板4的一端留有挡件容置部。
请参阅附图3或7，挂臂6的一端与第二节板2的侧面转动连接，挂臂6另一端为活动端且设有挂孔601，第一节板1和/或第二节板2侧面设有与挂臂6的挂孔601适配的挂钉101、201；具体地，挂臂6为弹性塑料件，折叠时挂臂6的活动端绕第二节板2转动至第一节板1 的挂钉101处时，稍向外拨动挂臂6使挂孔601和第一节板1上的挂钉101位置对应，然后将挂孔601挂入第一节板1上的挂钉101处，方便整体移动，此时第三节板3位于第一节板1和第二节板2之间，不会随意展开；展开状态下，用同样的方式将挂孔601挂入第二节板2上的挂钉201处，以使得挂臂6的活动端得到定位，从而不会随意摆动，安全可靠。
当本发明用于车辆抬高时，需要使用四个跳板，每个跳板只展开斜板4，安装挡件5至第一节板1一端的快拆固定部，并将斜板4至于车轮前，车轮沿斜板4和第一节板1滚动至挤压挡件5时停止，方便维护车辆底部；当用于两平台之间车辆过渡时，需要使用两个跳板，每个跳板完全展开，搭载于两平台之间，此时取下挡件5，连接挂臂6上的挂孔601与第二节板2上的挂钉201，车轮沿斜板4、第一节板1、第二节板2和第三节板3从一个平台行进至另一个平台；当不使用时，折叠斜板4、第一节板1和第三节板3，安装挡件5至第二节板2背面的挡件容置部，连接挂臂6上的挂孔601与第一节板1上的挂钉101，方便整体移动。
最后所应说明的是，以上具体实施方式仅用以说明本发明的技术方案而非限制，尽管参照实例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的精神和范围，其均应涵盖在本发明的权利要求范围当中。
