Description

一种无工具连接器 技术领域
本发明涉及一种型材框体之间的的连接器，尤其是一种无需工具的快速连接器。
背景技术
在搭建展示用的框架需要将各种型材互相之间连接在一起，连接件一般是一种连接锁，用于锁紧各种型材加以连接，制造结构复杂，成本高，同时一般需要工具加以固定，影响快速装卸。本公司曾经公开过一种快速的无工具的簧片锁，可以起到快速连接锁定型材的作用。但是由于该锁具在使用中，存在固定不到位，同时也存在不够美观，初始定位繁琐的问题。
发明的内容
本发明所要解决的技术问题是针对上述现有技术的不足，提供一种具有衬套结构的无工具连接器，连接更快捷、可靠，可直接与搭建结构中型材或装配部件锁定连接。
本发明的技术方案如下：
一种无工具连接器，该连接器包括衬套和锁体两部分组成，锁体活动的嵌入在衬套内，衬套是中空扁圆筒形结构，衬套右端有耳部，所述的衬套的侧壁是双层结构，内有左端闭合的孔道，所述的侧壁上还有一个长孔，位于所述孔道开口的右侧，锁体的侧壁有圆孔，连接杆穿过锁体的圆孔活动销接在所述的长孔内，将锁体和衬套嵌合。
由于连接件和圆孔是精密配合的，锁体与连接件相对位置是固定的，而销入在衬套上的长孔内，这样锁体就可以沿着衬套的长孔方向左右移动一定的范围。
衬套的耳部是用来从右边和型材的边缘固定的。
其中，锁体也是中空的扁筒结构，右端有盖板，左端有锁爪，中段有拉杆，拉杆穿过盖板与锁紧把手活动偏心铰接，锁爪连接在拉杆的另一端，锁紧把手通过偏心翻转可以带动拉杆，使锁爪达到闭合或张开状态。
进一步的，拉杆的中段有弹簧。这样当放松状态是，拉杆被弹簧弹回，就可以轻松的回缩。
进一步的，衬套的孔道内有弹簧。这样，在安装之初，放松锁体时，锁体被弹簧的弹出，直至连接杆抵住长孔的外端，这时锁爪就回缩在衬套内，不会妨碍两个型材框架的靠拢。当需要锁紧前，只要向左压缩锁体时，整个锁体可以向衬套内运动，连接杆运动至长孔的另一端，这时锁爪伸出相应的距离，这个距离可以使得锁爪卡在两个型材的外面，以便下一步的固定。
优选的，连接杆是平端螺杆。
进一步而言，衬套耳部还有螺钉孔。在安装时，用于将衬套固定在型材的一侧，更加牢固，也方便定位。
优选的，所述的盖板两边还有螺钉固定孔，盖板和锁体通过自攻螺钉固定。盖板是把手翻转运动的依靠基准，设置盖板也更美观。
进一步而言，锁体的拉杆左端部有两个相互交叉的锁定钩，交叉点的右侧有一个销接在锁体上的挡柱，所述的锁定钩的左端部还有一个回折部，所述的回折部插入在一个封闭腔体内，腔体的开口可以容纳回折部进出。这样的结构，可以使得；拉杆在回缩时，回折部可以卡主封闭腔体的内壁，不能随便移动，而在放松时，可以自由进出内壁，从而可以使得拉杆可以翻转锁定。
优选的，锁爪是三块活动簧片。可以张开和夹紧，张开时，张开的厚度超过两块型材的厚度，夹紧时可以将型材牢牢的锁定在一起。
本发明的有益效果：
1、本发明设计的技术方案，将锁体嵌合在衬套内，这样在使用时，先将衬套通过耳部固定在需要连接的型材一侧，这时锁体和锁爪弹缩在衬套内，不妨碍两个型材的拼接，然后按压锁体，锁体向衬套内运动，这是锁爪伸出一段距离，可以将两个型材卡入锁爪内，然后翻转把手，把手拉动拉杆将锁爪张开的部位锁紧，就可以将两个型材拼接。
2、本发明的简单快捷，实现了无工具的型材锁紧。相比原有连接器，安装更为便利。

具体实施方式
下面结合附图进一步对本发明中的技术方案进行描述。
一种无工具连接器，该连接器包括衬套11和锁体2两部分组成，锁体2活动的嵌入在衬套11内，衬套11是中空扁圆筒形结构，衬套11右端有耳部9，所述的衬套11的侧壁是双层结构，内有左端闭合的孔道14，所述的侧壁上还有一个长孔16，位于所述孔道14开口的右侧，锁体2的侧壁有圆孔17，连接杆13穿过锁体2的圆孔17活动销接在所述的长孔16内，将锁体2和衬套11嵌合。
其中，锁体2也是中空的扁筒结构，右端有盖板15，左端有锁爪1，中段有拉杆7，拉杆7穿过盖板15与锁紧把手5活动偏心铰接，锁爪1连接在拉杆7的另一端，锁紧把手5通过偏心翻转可以带动拉杆，使锁爪1达到闭合或张开状态。
其中，拉杆7的中段有弹簧一8。衬套的孔道内有弹簧二12。 连接杆13是平端螺杆。衬套耳部9还有螺钉孔一10。盖板15两边还有螺钉固定孔二，盖板15和锁体2通过自攻螺钉二6固定。锁体2的拉杆7左端部有两个相互交叉的锁定钩，交叉点的右侧有一个销接在锁体上的挡柱3，锁定钩的左端部还有一个回折部，回折部插入在一个封闭腔体内，腔体的开口可以容纳回折部进出。锁爪1是三块活动簧片。
组装时，如图3所示，将锁体2嵌入到衬套11内，再在衬套11的孔道14内放入弹簧二12，而后使用连接杆13塞入锁体2的圆孔17和衬套11的长孔16中。
使用时，第一步，如图4所示，将连接器放置在框体型材的一侧，用螺钉一4从耳部9的螺钉孔一10钻入到型材边框上，固定连接器。而后第二步如图5所示，按压锁体2，将锁爪1伸出，然后把第二件框体型材卡入在锁爪1内，再是第三步，如图6所示，翻转把手5，拉紧拉杆7，锁爪1夹紧，从而将两个框体的型材连接在一起，整体的效果如图7所示。
