Description

一种捆绑器 技术领域
本发明属于运输捆绑技术领域，涉及一种捆绑器。
背景技术
捆绑器是手驱动的张力设备，捆绑器通过将绑带的其中一端卷绕收回来实现捆绑收紧。
捆绑器结构较成熟，例如中国专利文献公开的一种结构改良的手拉器【授权公告号CN 202368808 U】，包括有手柄、卷轴、棘轮、以及控制拉板，卷轴两端穿过手柄的两块侧板，两个棘轮套设于卷轴左右两侧，控制拉板位于手柄的两块侧板之间，其中部具有开口，开口处的后端设有第一扳动片，控制拉板的前端具有凹进部，凹进部的内侧设有第二扳动片。卷轴用于卷绕绑带，在收紧绑带时通过转动手柄带动棘轮转动，棘轮转动带动卷轴转动，卷轴转动使得卷绕在卷轴上的绑带收卷将绑带收紧。
目前卷轴通常采用两根半月轴组成，两根半月轴之间具有间隙，两根半月轴相对的侧面为平面，两根半月轴上相对远离的周面为光滑的弧面，半月轴上弧面和平面之间通过圆弧面过度。绑带在卷绕在卷轴上时其端部先穿过两根半月轴的间隙，绑带的端部贴靠在其中一根半月轴的弧面上，然后绑带再一圈一圈的卷绕在两根半月轴上，位于最内圈的绑带将绑带的端部压紧在弧面上，且位于外圈的绑带会对位于内圈的绑带施加压紧力，因此位于最内圈的绑带受到的压紧力较大，会紧紧的贴靠在弧面上。在捆绑器收紧绑带使得绑带绷紧时，由于绑带绷的较紧，会使得卷绕在两根半月轴上的绑带在棘轮每转动一个齿时会相对两根半月轴出现细微的周向转动的情况，在松开绑带后卷绕在两根半月轴上的 绑带又会复位；由于半月轴上的弧面为光滑的，位于最内圈的绑带与弧面之间仅通过摩擦力来实现周向定位，摩擦力较小，因此位于最内圈的绑带在收紧绑带时会相对半月轴有细微的周向转动，松开绑带后又会复位，在此过程中绑带会与半月轴之间具有摩擦，会造成绑带的磨损，长时间使用后会导致绑带断裂的情况，其中最容易出现磨损的一段是与半月轴上圆弧面贴靠的一段。
发明内容
本发明的目的是针对现有的技术存在上述问题，提出了一种捆绑器，本发明解决的技术问题是使得绑带与带轴始终保持同步转动。
本发明的目的可通过下列技术方案来实现：
一种捆绑器，包括支架、手柄和带轴，所述支架和手柄通过带轴枢接，所述带轴上固定有棘轮，所述手柄上设有能卡接在棘轮上并能带动棘轮正转的推板，所述支架上设有能防止棘轮反转的止动板，所述带轴包括两根半月轴，两根所述半月轴之间具有供绑带穿过的间隙，两根半月轴上相对远离的周面为呈弧面的贴靠面，其特征在于，所述贴靠面上具有若干凸起部，所述凸起部之间为可供绑带在形变后嵌入的嵌入部。
支架上远离带轴的一端固定有固定轴，捆绑器在使用时需要采用长绑带和短绑带来实现捆绑，其中短绑带的一端与固定轴固定，短绑带的另一端固定有挂钩，长绑带的一端与带轴连接，长绑带的另一端固定有挂钩，在捆绑货物时长绑带的挂钩和短绑带的挂钩钩住，再通过扳动手柄使得棘轮转动带动带轴转动，带轴转动会收紧长绑带，因而使得长绑带和短绑带能捆紧货物。
绑带与带轴连接时其端部穿过两根半月轴的间隙后贴靠在其中一根半月轴的贴靠面上，绑带再一圈一圈的绕在两根半月轴上，此时绑带处于绷紧状态，通过外圈的绑带将内圈的绑带压紧从而 避免绑带从两根半月轴上脱离，与两根半月轴的贴靠面贴靠位于最内圈的绑带与凸起部抵靠，由于最内圈的绑带受到外圈绑带的压力最大，且由于凸起部之间具有嵌入部，因此，最内圈的绑带会发生形变并嵌入嵌入部内形成形变段，形变段会在两根半月轴转动时与凸起部抵靠，因此能避免最内圈的绑带在两根半月轴转动时与半月轴之间出现位移，因此绑带与两根半月轴始终保持同步转动，也就避免了最内圈绑带与半月轴之间的摩擦导致绑带磨损断裂的情况，提高绑带的使用寿命。
通过嵌入嵌入部内的绑带与凸起部抵靠使得绑带相对半月轴周向定位，相对通过摩擦的方式，凸起部所提供的阻力更大，能更容易将绑带周向定位在半月轴上，且绑带嵌入嵌入部是通过绑带自生绕卷所形成的压紧力实现，无需增加其它对应结构，因此结构简单。
增加的凸起部能增强半月轴的强度，使得半月轴在径向上的抗弯曲强度更大，能避免在收紧绑带时被绑带的收紧力压弯变形，由于半月轴不会被弯曲，也就是在使用过程中半月轴的贴靠面不会出现弯曲隆起的情况，因而降低由于半月轴弯曲形变带来对绷带划伤的风险，进一步避免了绑带被磨损导致断裂的情况，提高绑带的使用寿命。
作为第一种情况，在上述的捆绑器中，所述凸起部包括若干呈长条形的凸棱，所述凸棱的长度方向与半月轴的长度方形平行，相邻凸棱之间形成凹槽，所述凹槽为上述嵌入部。位于最内圈绑带的形变段嵌入相邻凸棱之间的嵌入部内，形变段的两端与相邻凸棱抵靠，在两根半月轴转动时形变段与半月轴转动方向一侧的凸棱抵靠，形变段被定位在凹槽内，使得绑带与两根半月轴始终保持同步转动，也就避免最内圈绑带相对半月轴之间出现位移，避免了绑带被半月轴磨损导致断裂的情况，提高绑带的使用寿命。
在上述的捆绑器中，所述凸棱的侧面为圆弧面。最内圈绑带 与凸棱的侧面贴靠，为圆弧面的凸棱侧面能使得绑带受到的压力均匀，同时使得绑带与侧面贴靠的一段和形变嵌入嵌入部的一端之间圆滑过渡，避免损坏绑带。
在上述的捆绑器中，相邻所述凸棱之间间隔的弧度大小均相同，贴靠面位于相邻凸棱之间的弧长大小为凸棱直径大小的1倍～2.5倍。相邻凸棱之间间隔弧度相同使得绑带的形变段长度均相同，在半月轴转动时位于最内圈绑带每一段的形变段提供的阻力均相同；同时在凸棱的直径与贴靠面位于相邻凸棱之间的弧长小于上述关系值时会由于嵌入部的空间不够导致最内圈绑带无法形变嵌入嵌入部；在凸棱的直径与贴靠面位于相邻凸棱之间的弧长大于上述关系值时会由于最内圈绑带嵌入嵌入部的形变段过长导致形变段自身支撑力较弱，在半月轴转动时形变段自身中段会相对半月轴出现位移，导致最内圈绑带相对半月轴出现位移的情况；而上述凸棱的直径与贴靠面位于相邻凸棱之间的弧长的关系值使得最内圈的绑带既能形变嵌入嵌入部，同时嵌入嵌入部的形变段自身长度适中，形变段自身支撑力较大，能在半月轴转动时形状保持不变，因而能使得绑带与两根半月轴始终保持同步转动，避免绑带磨损断裂。
在上述的捆绑器中，所述支架上开有枢接孔一，所述手柄上开有枢接孔二，两根所述半月轴穿过枢接孔一和枢接孔二，所述半月轴上凸棱的侧面能与枢接孔一的孔壁以及枢接孔二的孔壁贴靠。由于凸棱的侧面与枢接孔一的孔壁以及枢接孔二的孔壁接触面积较小，两根半月轴与支架和手柄的接触面较小，所受到的摩擦较少，因此两根半月轴在相对支架和手柄转动时受到的阻力也较小，从而能更轻松的使得两根半月轴相对支架转动，使得捆紧绑带更省力。
作为第二种情况，在上述的捆绑器中，所述凸起部包括若干斜凸棱一和若干斜凸棱二，所述斜凸棱一和斜凸棱二之间相互交 叉形成网状结构，相邻的斜凸棱一与相邻的斜凸棱二之间形成凹坑，所述凹坑为上述嵌入部。位于最内圈绑带在外圈压力的作用下嵌入凹坑内，嵌入凹坑内的绑带其形状与凹坑相匹配，嵌入凹坑内的绑带每个边均与对应斜凸棱一和斜凸棱二抵靠，在两根半月轴转动时嵌入凹坑内的绑带与半月轴转动方向一侧的斜凸棱一和斜凸棱二抵靠，嵌入凹坑内的绑带被定位在凹坑内，使得绑带与两根半月轴始终保持同步转动，也就避免最内圈绑带相对半月轴之间出现位移，避免了绑带被半月轴磨损导致断裂的情况，提高绑带的使用寿命。
在上述的捆绑器中，所述斜凸棱一的侧面和斜凸棱二的侧面均为圆弧面。最内圈绑带与斜凸棱一和斜凸棱二的侧面贴靠，为圆弧面的斜凸棱一侧面和斜凸棱二侧面能使得绑带受到的压力均匀，同时使得绑带上与斜凸棱一和斜凸棱二贴靠的一段和形变嵌入凹坑的绑带之间圆滑过渡，避免损坏绑带。
在上述的捆绑器中，相邻所述斜凸棱一之间间距大小均相同，相邻所述斜凸棱二之间间距大小均相同，且相邻所述斜凸棱一之间间距大小与相邻所述斜凸棱二之间间距大小相同。该结构使得形成的凹坑其每个侧边的长度均相同，也就使得嵌入凹坑内的绑带与斜凸棱一和斜凸棱二抵靠时受到的反作用力相同，在两根半月轴转动时，避免嵌入凹坑内的绑带因受力不同出现进一步形变导致绑带出现位移的情况，使得绑带能相对两根半月轴周向定位，保证绑带的使用寿命。
作为第三种情况，在上述的捆绑器中，所述凸起部包括若干呈半球型的凸点，若干所述凸点沿贴靠面的长度方向等间距分布，若干所述凸点沿贴靠面的圆弧方向等弧度分布，相邻所述凸点之间形成上述嵌入部。位于最内圈绑带在外圈压力的作用下嵌入凸点之间的嵌入部内，嵌入嵌入部内的绑带其形状与嵌入部相匹配，嵌入嵌入部内的绑带会与对应凸点抵靠，在两根半月轴转动时嵌 入嵌入部内的绑带与半月轴转动方向一侧的凸点抵靠，嵌入嵌入部内的绑带被定位在嵌入部内，使得绑带与两根半月轴始终保持同步转动，也就避免最内圈绑带相对半月轴之间出现位移，避免了绑带被半月轴磨损导致断裂的情况，提高绑带的使用寿命。
在上述的捆绑器中，所述凸点呈半球形。该结构的凸点使得绑带能覆盖在其上，且避免局部应力集中导致绑带被刺穿的情况，避免损坏绑带。
与现有技术相比，本捆绑器使得绑带与两根半月轴始终保持同步转动，避免了最内圈绑带与半月轴之间的摩擦导致绑带磨损断裂的情况，具有提高绑带的使用寿命的优点。

具体实施方式
以下是本发明的具体实施例并结合附图，对本发明的技术方案作进一步的描述，但本发明并不限于这些实施例。
实施例一
如图1和图2所示，捆绑器包括支架1、手柄2和带轴3，带轴3包括两根半月轴31，两根半月轴31之间具有供绑带8穿过的间隙32，支架1的一端和手柄2的一端通过带轴3枢接，支架1上开有枢接孔一11，手柄2上开有枢接孔二21，两根半月轴31穿过枢接孔一11和枢接孔二21；支架1上远离带轴3的一端固定有固定轴12，带轴3上固定有棘轮4，棘轮4位于支架1和手柄2之间，棘轮4的中部开有两个半月孔，两根半月轴31分别穿过半月孔，手柄2上设有能卡接在棘轮4并能带动棘轮4正转的推板22，推板22能相对手柄2滑动实现与棘轮4的脱离或者啮合，支架1上能防止棘轮4反转的止动板13，止动板13和支架1之间具有弹簧14，在棘轮4转动是棘轮4能推动止动板13压缩弹簧14，在棘轮4转动到位后在弹簧14的作用下止动板13重新卡入棘轮4内。
如图2至图6所示，两根半月轴31上相对的侧面为平面311，两根半月轴31上相对远离的周面为呈弧面的贴靠面312，平面311和贴靠面312之间通过过渡圆弧面313连接，贴靠面312上具有若干凸起部33，凸起部33之间为可供绑带8在形变后嵌入的嵌入部331。具体来说，凸起部33包括若干呈长条形的凸棱5，凸棱5的侧面为圆弧面，凸棱5的长度方向与半月轴31的长度方形平行，半月轴31上凸棱5的侧面与枢接孔一11的孔壁以及枢接孔二21的孔壁贴靠；相邻凸棱5之间间隔的弧度大小均相同，贴靠面312位于相邻凸棱5之间的弧长大小为凸棱5直径大小的1倍～2.5倍，本实施例一中，贴靠面312位于相邻凸棱5之间的弧长大小为凸棱5直径大小的1倍、1.5倍或者2.5倍，相邻凸棱5之间形成凹槽51，凹槽51为嵌入部331，
如图2和图3所示，绑带8与带轴3连接时其端部穿过两根半月轴31的间隙32后贴靠在其中一根半月轴31的贴靠面312上，绑带8再一圈一圈的绕在两根半月轴31上，此时绑带8处于绷紧状态，通过外圈的绑带8将内圈的绑带8压紧从而避免绑带8从两根半月轴31上脱离，与两根半月轴31的贴靠面312贴靠位于最内圈的绑带8与凸起部33抵靠，由于最内圈的绑带8受到外圈绑带8的压力最大，且由于凸起部33之间具有嵌入部331，因此，最内圈的绑带8会发生形变并嵌入嵌入部331内形成形变段81，形变段81会在两根半月轴31转动时与凸起部33抵靠，因此能避免最内圈的绑带8在两根半月轴31转动时与半月轴31之间出现位移，也就避免了最内圈绑带8与半月轴31之间的摩擦导致绑带8磨损断裂的情况，提高绑带8的使用寿命。
实施例二
本实施例同实施例一的结构及原理基本相同，不一样的地方在于：如图7所示，凸起部33包括若干斜凸棱一6和若干斜凸棱二61，斜凸棱一6的侧面和斜凸棱二61的侧面均为圆弧面，相邻斜凸棱一6之间间距大小均相同，相邻斜凸棱二61之间间距大小均相同，且相邻所述斜凸棱一6之间间距大小与相邻所述斜凸棱二61之间间距大小相同，斜凸棱一6和斜凸棱二61之间相互交叉形成网状结构，相邻的斜凸棱一6与相邻的斜凸棱二61之间形成凹坑62，凹坑62为嵌入部331。位于最内圈绑带8在外圈压力的作用下嵌入凹坑62内，嵌入凹坑62内的绑带8其形状与凹坑62相匹配，嵌入凹坑62内的绑带8每个边均与对应斜凸棱一6和斜凸棱二61抵靠，在两根半月轴31转动时嵌入凹坑62内的绑带8与半月轴31转动方向一侧的斜凸棱一6和斜凸棱二61抵靠，嵌入凹坑62内的绑带8被定位在凹坑62内，也就避免最内圈绑带8相对半月轴31之间出现位移，避免了绑带8被半月轴31磨损导致断裂的情况，提高绑带8的使用寿命。
实施例三
本实施例同实施例一的结构及原理基本相同，不一样的地方在于：如图8所示，凸起部33包括若干呈半球型的凸点7，凸点7呈半球形，若干凸点7沿贴靠面312的长度方向等间距分布，若干凸点7沿贴靠面312的圆弧方向等弧度分布，相邻凸点7之间形成上述嵌入部331。位于最内圈绑带8在外圈压力的作用下嵌入凸点7之间的嵌入部331内，嵌入嵌入部331内的绑带8其形状与嵌入部331相匹配，嵌入嵌入部331内的绑带8会与对应凸点7抵靠，在两根半月轴31转动时嵌入嵌入部331内的绑带8与半月轴31转动方向一侧的凸点7抵靠，嵌入嵌入部331内的绑带8被定位在嵌入部331内，也就避免最内圈绑带8相对半月轴31之间出现位移，避免了绑带8被半月轴31磨损导致断裂的情况，提高绑带8的使用寿命。
