Description
技术领域
本发明涉及一种膨胀螺丝,尤其是能固化在墙体内的膨胀螺丝。
背景技术
目前,一般的膨胀螺丝,螺钉一头是螺纹,一头是椎度,外面包一铁皮,铁皮圆筒一半有若干切口,固定物件后,螺纹处与铁皮圆筒间有一定的空隙,可以晃动,一般用于防护栏、雨蓬、空调等在水泥、砖等材料上的紧固,但它的固定并不十分可靠,如果载荷有较大震动,可能发生松脱,因此不推荐用于安装吊扇等;一般的膨胀螺丝只有在椎度的大边挤压铁皮,铁皮的积压变形是一定的,产生的摩擦阻力有限,载荷过大也不宜使用。锤击式膨胀螺栓由衬套和锤击钉组成,衬套的前端为开设有若干条沿中心轴线方向的槽缝的膨胀部,衬套沿中心轴线方向设置有一容置锤击钉的穿置洞道,穿置洞道在衬套的膨胀部处设置有一与锤击钉的推进端匹配的封闭端,锤击式膨胀螺栓的衬套变形是一定的,产生的摩擦阻力有限,载荷过大不宜使用;而螺纹处与墙上的洞有一定的空隙,可以晃动,如果载荷有较大震动,可能发生松脱,因此不推荐用于安装吊扇等;如果墙体的硬度很大,锤击钉难于穿过衬套的封闭端,此时锤击钉随时会后退脱落。
发明内容
本发明的目的在于克服现有技术存在的不足之处,而提供一种能够固化在墙体内且带胶的膨胀螺丝,该装置具有结构简单、使用操作方便、使用范围广、固定效果好的优点。
为实现上述目的,本发明的技术解决方案是:
带胶的膨胀螺丝由衬套、螺丝钉、胶体组成,旋转螺丝钉,螺丝钉向衬套内移动,尖端刺破胶体外膜,挤压胶体,软胶被挤入内螺纹与螺丝钉螺纹间、槽缝内、螺丝钉与膨胀片内壁间、衬套与洞内壁间的空间,尖端继续向下移动,挤压膨胀片向外膨胀,涨满整个洞,衬套就抽不出来了,同时钉头压住被固定件,过一段时间后胶凝固,这样膨胀螺丝就被固化在洞内。
本发明的有益效果是:
结构简单:由衬套、螺丝钉、胶体组成。
使用操作方便:首先把带有胶体的衬套用力塞入洞内,再将螺丝钉穿入固定件内,最后,把螺丝钉旋转入衬套。
使用范围广:可用于防护栏、雨蓬、空调等在水泥、砖等材料上的紧固,也可以用于负荷有较大震动的物件,如安装吊扇等,而且较大负荷的固定也能应用。
固定效果好:胶凝固后,膨胀螺丝就被固化在洞内。

图2是本发明衬套塞入墙体的洞示意图。
图3是本发明螺丝钉旋转入衬套示意图。
图4是本发明软胶分布示意图。
具体实施方式
如图1所示,带胶的内螺旋式膨胀螺丝由衬套(1)、螺丝钉(8)、胶体(13)组成,胶体(13)在衬套(1)内下部,螺丝钉(8)旋转在衬套(1)内;衬套上部(7)内面有内螺纹(2),衬套(1)下部被槽缝(3)分割成多块膨胀片(4),多块膨胀片(4)略微向外分开,膨胀片(4)的下部是尖端(6),在尖端(6)的上方是摩擦带(5);螺丝钉(8)的上端为钉头(9),螺丝钉(8)的中端为螺纹(11),螺丝钉(8)的下端为钉尖(10);胶体(13)由软胶(14)和胶体外膜(15)组成,胶体外膜(15)包裹软胶(14)。
如图2所示,在A中,在墙体(16)内打一个洞(17);在B中,把带有胶体(13)的衬套(1)用力塞入洞(17)口,洞(17)口挤压尖端(6),尖端(6)向内收缩;在C中,带有胶体(13)的衬套(1)被塞入洞(17)内,膨胀片(4)反弹挤压洞(17)内壁。
如图3所示,在D中,螺丝钉(8)穿入被固定件(12),再把螺丝钉(8)旋转入衬套(1);在E中,螺丝钉(8)继续向下旋转,钉尖(10)刺破胶体(13)的胶体外膜(15),软胶(14)被挤出;在F中,螺丝钉(8)继续向下旋转,软胶(14)继续被挤出,软胶(14)被挤入内螺纹(2)与螺丝钉螺纹(11)间、槽缝(3)内、衬套(1)与洞(17)内壁间的空间;在G中,螺丝钉(8)继续向下旋转,软胶(14)继续被挤入内螺纹(2)与螺丝钉螺纹(11)间、槽缝(3)内、衬套(1)与洞(17)内壁间的空间,尖端(6)继续向下移动,同时积压膨胀片(4)向外膨胀,涨满整个洞,此时,衬套(1)就抽不出来了,同时,钉头(9)压住被固定件(12)。
如图4所示,软胶(14)被挤入内螺纹(2)与螺丝钉螺纹(11)间、槽缝(3)内、螺丝钉(8)与膨胀片(4)内壁间、衬套(1)与洞(17)内壁间的空间。
以上所述,仅为本发明较佳实施例而已,故不能以此限定本发明实施的范围,即依本发明申请专利范围及说明书内容所作的等效变化与修饰,皆应仍属本发明专利涵盖的范围内。
