如图1、2和3所示,所述的台框1有台板2安置面,左、右凸台式短边框13、14的顶面高于台板2的安置面,在前、后横档11、12上分别设有二个导向限位片,包括固定在前横档11上的第一、第二导向限位片51、52,和后横档12上的第三、第四导向限位片53、54;在第一、第二、第三、第四导向限位片51、52、53、54的下部分别固设有第一、第二、第三、第四弹簧卡扣61、62、63、64,所述的双面台板通过第一、第二、第三、第四导向限位片51、52、53、54的斜面将台板2置入台框时,由左、右凸台式短边框13、14和第一、第二、第三、第四导向限位片51、52、53、54对台板2的前后左右进行限位,可以限制所述双面台板2在水平方向上的移动;同时,台板2被第一、第二、第三、第四弹簧卡扣61、62、63、64卡紧固定在台框1上,即可限制所述双面台板2在垂直方向上的移动,如图2所示,当工作台板朝上,为工作台;当防滑板朝上为操作台。本实施例的弹簧卡扣为偏心轴弹簧扣,如图4所示。
本实施例所述的工作台板为密度板21,如图1所示,依序通过敲击板7、压板和紧固螺钉9与防滑板22固定连接,其中,所述的压板位置与第一、第二、第三、第四弹簧卡扣61、62、63、64匹配,包括第一、第二、第三、第四压板81、82、83、84,所述的密度板21和防滑板22均设有与上述弹簧卡扣位置相对应的第一、第二、第三、第四密度板卡槽211、212、213、214和与所述卡槽形状匹配的第一、第二、第三、第四防滑板卡槽221、222、223、224,密度板21与防滑板22贴合时,所述的密度板卡槽和防滑板卡槽位置相同,通过弹簧卡扣相互卡紧限位。

为方便带电操作,如图8所示,在一侧凸台式短边框的外侧设有插电板。
所述敲击板7为钢性材料,主要作为刀片切割的底板,或其他使用敲击工具的底板。比如可在所述敲击板7上,用榔头敲整铁丝等。
如图1和图9所示,所述的防滑板22为塑胶面板,其表面有网格状防滑纹225。
如图3、图5和7所示,为了保证所述的台框1的强度,所述的台框1中,前、后横档11、12之间连接有四个相互平行的第一、第二、第三、第四支撑杆151、152、153、154,一对短边框之间连接一根支撑轴16,所述的支撑轴16底 部固定有左、右卡扣161、162,如图5、6和7所示,用于固定折叠收拢的伸缩式折叠支撑架3时,分别固定左圆柱卡头3131和右圆柱卡头3231。

本实用新型提供所述的伸缩式折叠支撑架3为一可折叠、可收缩脚架,带有伸缩结构且至少可以进行一次伸缩的四个支撑柱,分别通过左、右横梁313、323由二二支撑柱构成左、右“H”形支撑架31、32,即设置在所述台框1的底部相对边,所述的左、右“H”形支撑架31、32分别铰接在台框1底部的左、右凸台式短边框13、14侧,其中:
左“H”形支撑架31有左“H”形支撑架第一、第二支撑柱311、312及左横梁313,在左横梁313上设有左圆柱卡头3131,与左卡扣161配合;
右“H”形支撑架32有右“H”形支撑架第一、第二支撑柱321、322及右横梁323,在右横梁323上设有右圆柱卡头3231,右卡扣162配合;

将所述伸缩式折叠支撑架3的四个支撑柱下方的伸缩部缩回并向内折叠时,所述的左一、左二带有单向折叠转轴的支杆3111、3121和右一、右二带有单向折叠转轴的支杆3211、3221沿折叠转轴折叠,带动伸缩式折叠支撑架3向内收拢,使左、右圆柱卡头3131、3231与支撑轴16上的卡扣161互相卡紧,伸缩式折叠支撑架3被收拢在台框1底部,固定在台框1底部的四个脚轮接触地面滚动。
作为工作台使用的安装方法:先将所述伸缩式折叠支撑架3撑开后,即将左“H”形支撑架第一、第二支撑柱311、312;右“H”形支撑架第一、第二支撑柱321、322拉伸,使双面台板2基本处于正常成年人身体的胯部位置,双面台板2中密度板21朝上,即算安装完成。如果有工具,可将工具等置于工作台面,或插在所述台框1的凸台式短边框的槽或孔内。本实施例中的产品完全可以支撑家用的小型机械类产品的重量。
如要收起,可将伸缩式折叠支撑架3折叠起,提拎把手10将其放入储物箱、 车厢或其他容置位置即可,方便收藏。
实施例2
请参阅图8为本实用新型作为工作台侧视示意图和图9为本实用新型小型脚手架具体实施例。
其他结构与实施例1相同,如图9所示,双面台板2中防滑板22朝上,本实用新型可以作为操作台或小型脚手架,操作人员可站立在防滑板22上,在实施例1的基础上,所述台框中,台框1中一横档的外侧装有把手10,方便伸缩式折叠支撑架折叠收缩后搬运。
将所述伸缩式折叠支撑架3撑开后,各支撑柱无需拉伸,配合双面台板2中的防滑板22,即可使用。
当左凸台式短边框13上设有存贮工具的槽或孔时,可在右凸台式短边框14外侧固定有狭条状电源插座板,方便使用带电操作的工具,如钻孔等。
由于防滑板22上带有网格状防滑纹225,作为脚手架使用时,不但结构稳固,而且板面防滑。
如果使用者需要从高度较高处拿取物品或进行其他动作,则使用者可站立于防滑板22上,但折叠式工作台太高会使人站立不稳。因此,所述支撑柱无需拉伸,一般正常成年人可轻松站上。相比于所述密度板21,防滑板22有网格状防滑纹225,站立在防滑板22上时更稳定。
