Description

一种具有三角警告牌的平板手推车
技术领域
本发明属于平板手推车领域，更具体地说，尤其涉及一种适合放在汽车尾箱为广大司机使用的具有三角警告牌的平板手推车。
背景技术
平板手推车是一种平面运输设备，在小范围内作业具有方便性和实用性，其广泛地在仓库、制造工厂、百货公司、物流中心、货运站或配送途中之短程搬运使用。
中国发明专利，公告号为 CN205417687U ，发明名称为一种具有发光警示装置的平板手推车，公开了在平板手推车上设置三角警告牌的技术方案，但该技术方案公开的三角警告牌在符合机动车用三角警告牌尺寸标准的情况下，车体会比较大，不利于携带和存放，如果车体做的太小，三角警告牌的尺寸则会不符合机动车用三角警告牌尺寸标准，警告牌的理论边长为 500mm ± 50mm ，反射器宽度为 25~50mm ，外边沿宽度不得超过 5mm 。
发明内容
本发明的目的是为了解决上述存在的问题，克服车体体积受机动车用三角警告牌尺寸标准的限制无法做得更小的问题，提供一种三角警示牌在符合机动车用三角警告牌尺寸标准的前提下，车体可以做的比较小，便于存放和携带的具有三角警告牌的平板手推车。
本发明通过以下技术方案实现。
本发明是一种具有三角警告牌的平板手推车，包括把手、承重板和脚轮，脚轮固定在承重板的底部，把手通过固定结构固定在承重板的上部，所述承重板上设有能相对承重板翻转打开的盖板，该盖板上设有可折叠式三角警告牌。三角警告牌采用折叠式结构，可以在符合机动车用三角警告牌尺寸标准的前提下，车体可以做的更小，体积更轻，便于携带存放。
优选地，所述折叠式三角警告牌包括下边板、上角板、左角板及右角板，下边板固定在盖板的下部，上角板、左角板及右角板分别与盖板的上缘、左缘及右缘铰接、并能相对盖板转动收合在盖板外侧面和展开，上角板、左角板及右角板在展开状态时，上角板、左角板、右角板下边板及盖板的外侧面能共同形成反光的三角形框状结构。
优选地，所述盖板的左右上角位置分别具有左连接板和右连接板，上角板、左角板、右角板、下边板、左连接板和右连接板的外侧面共同围成反光的三角形框状结构，上角板的左右下缘分别与左连接板及右连接板的上缘铰接、并能相对左连接板及右连接板转动，左角板的上右缘与左连接板的左缘铰接，下右缘与盖板的左缘铰接、并能相对左连接板及盖板转动，右角板的上左缘与右连接板的右缘铰接、下左缘与盖板的右缘铰接、并能相对右连接板及盖板转动。通过以上结构，可以充分利用空间，上角板、左角板及右角板折叠收回后不超出盖板覆盖的面积，保证盖板能转动收合于承重板上。
优选地，所述左连接板的上缘与左缘相互垂直，右连接板的上缘与右缘相互垂直，下边板呈矩形形状，其水平设置。该设置是为了使上角板能竖向翻转折叠，左角板和右角板能水平向翻转折叠，折叠时可互不干扰。
优选地，所述左角板与右角板的宽度之和小于下边板的宽度，下边板的宽度小于盖板的宽度。以保证折叠时，上角板、左角板和右角板不重叠，完全折叠后处于同一平面，有利于方便固定、避免磕碰，同时，整个折叠式三角警告牌折叠后的高度及宽度与盖板的高度及宽度相当，方便盖板盖合。
优选地，所述折叠式三角警告牌的三个外角加工成圆弧状。以方便上角板、左角板和右角板三者完全折叠时，三者的外角与角板边缘之间留有让手指伸入的空位，方便将三者打开。
优选地，所述盖板通过设置在承重板上的水平转轴与承重板转动连接，盖板能以水平转轴为轴相对承重板向上翻转打开 90 度，同时，承重板上设有在盖板处于盖合状态时能将盖板锁定的锁定机构。盖板能翻转打开 90 度可以提供最佳的反射角度，保证警示效果，锁定机构可防止盖板在车体行进中由于颠簸产生震动造成损伤。
优选地，所述水平转轴上套装有弹簧，弹簧的一端与盖板相抵，弹簧的另一端与承重板相抵，以能在盖板相对承重板打开 90 度时为盖板提供支撑力。弹簧支撑可以提高折叠式三角警告牌工作时的稳定性，防止因风力等外力导致叠式三角警告牌的反射角度产生变化。
优选地，所述承重板的承重面与盖板对应的位置设有下沉的储物槽，盖板设在储物槽的开口处，盖板能打开和盖合储物槽的开口，盖板盖合时其上表面与承重板的承重面平齐。储物槽可提供储存空间，可放置一些小工具，或购物袋，为使用者提供便利。
优选地，所述储物槽的开口处设有承托杆，承托杆一端与开口一边的承重板部位铰接、并能相对承重板转动，另一端卡入开口另一相对边上设有的卡槽中、并能从卡槽中脱离。承托杆可为折叠后的上角板、左角板和右角板提供支撑固定，防止在车体移动过程中三者出现晃动造成损伤。
本发明的有益效果在于，（ 1 ）三角警告牌采用折叠式结构，可以在符合机动车用三角警告牌尺寸标准前提下，车体体积可以做的更小，重量更轻，便于携带和存放；（ 2 ）不仅可以满足日常运输需求，还可以在夜间车辆故障时作为三角警告牌使用，为过往车辆提供警示，警示效果明显，保证行车安全。
