Description

分步释放拉紧机机壳
技术领域
本实用新型涉及一种手动捆绑工具，分步释放拉紧机中的主要部件，分步释放拉紧机机壳。由其组装成的拉紧机，特别适用于运输车辆在运输货物时，使货物捆绑牢靠，并可防止释放操作时货物突然倾翻事故的发生。
背景技术
专利号01274274.0“二次释放拉紧机”虽也提供了一种既有拉紧功能，又具有分次释放功能的拉紧机，但机壳结构还不够完善。
发明内容
本实用新型所要解决的技术问题是：提供一种分步释放拉紧机机壳，设计合理、完善，用其安装在分步释放拉紧机上，使其既有拉紧机功能，又有缓慢释放功能，并缓慢释放效果好，能确保卸货安全，使用更安全、可靠。
本实用新型解决上述技术问题所采用的技术方案为：分步释放拉紧机机壳，机壳边缘上有锁定槽和松驰槽，所述的松驰槽旁还有释放槽，机壳上还有由释放槽和在释放槽边处，还连接可转动的与拉紧机上棘齿配合的滑齿，构成的缓释装置，而滑齿的顶点高于棘齿或与其持平。
与现有技术相比，本实用新型的优点在于：因在机壳的头部增加了一个带弧形的滑槽作为释放槽，并在释放槽处还连接可转动并与棘齿配合的滑齿构成的缓释装置，用其进行分步释放。在此释放槽内将拉紧机上的大挡板来回摇动几次，棘齿会一齿一齿放松，则绑带也随之释放一个齿距的长度，一点点放松，使绑带缓慢放松，待绑带上张力较小时，再进行第二步释放。将大挡板固定在松驰槽内，棘齿才处于完全释放状态，安全放松绑带，货物才会被松绑。采用分步释放，逐步释放绑带的张力，就可防止货物突然松绑，突然倾斜、倾翻、倒塌而造成的伤人，损、毁货物的事故，并此装置简单、易制造、加工，只需增加滑齿这一简单零件。选用此结构的机壳组装拉紧机，缓慢释放效果好，并大大提高了其的使用安全可靠性，为拉紧机更新换代的理想部件。
附图说明

图2.本实用新型的使用状态图。
图3.释放过程示意图a、b、c、d、e。
具体实施方式
以下结合附图实施例对本实用新型作进一步详细描述。
机壳8，中间截面为  形，两端开口无底面，两侧壁上有大、小通孔和长条形滑槽，一开口端头部边缘有一松驰槽1，其相邻处还有一释放槽3，其下方有通孔6和弧形定位槽2，与松驰槽1相对应处有一锁定槽7。
滑齿4，中间有通孔，一端为圆弧形与棘齿10配合，一端为弯折形。
释放槽3，为在机壳8头部边缘上开有的圆弧形滑槽，其圆弧形与棘齿10圆弧形方向一致并形状相匹配或形状不一样，并圆弧形长度为棘齿10齿长度的2-3倍。
用铆钉5将滑齿4，固定在机壳8头部边缘释放槽3下方的通孔6内，并将滑齿4的一弯折端，插入机壳8上的定位槽2内，滑齿4可绕铆钉5转动，并与棘齿10配合，滑齿4的顶点高于棘齿10或与棘齿10持平。
将带有释放装置的机壳8与棘齿10、手柄12用两半轴9连接成整体，并和其它部件装配成分步释放拉紧机。
若要卸货，需先给货物松绑，先扳起拉紧机的手柄12，将大挡板11从锁定槽7中拉出，转动手柄12，将大挡板11先放置在释放槽3内，继续向前推动手柄12，大挡板11沿释放槽3逆时针方向滑动，并滑越过滑齿4的最高顶点，如图3a所示，继续推动手柄12，使大挡板11逆时针方向滑动，直到释放槽3的底部，如图3b所示，棘齿10在绑带拉力的作用下，顺时针方向转动，其上的齿推动大挡板11沿释放槽3顺时针方向滑动，直到碰到滑齿4，嵌在棘齿10的齿与滑齿4间，如图3c所示，继续顺时针方向搬动手柄12，大挡板11推动滑齿4，并沿滑齿4的顶点越过滑齿4，滑入释放槽3，直到碰到槽边被顶住，绑带被放松了一个齿距的长度，如图3d所示。
反复上述操作，棘齿10一齿齿顺时针方向向后转动，绑带也缓慢被放松，若将大挡板11插入松驰槽1内，带子完全放松，拉动绑带，棘齿10与两半轴9一起转动，从而将绑带从两半轴9中脱出，货物松绑，如图3e所示。
