Abstract
本发明公开了一种膨胀螺套,包含一第一膨胀筋和一第二膨胀筋,所述的第一膨胀筋上设有一第一卡齿,所述的第二膨胀筋上设有一第二卡齿,作为本发明较佳的实施例,所述的第一膨胀筋和第二膨胀筋上设有若干凹槽,作为本发明较佳的实施例,所述的第一卡齿和第二卡齿相互对称。由于本发明的膨胀螺套上设置了两个对称的卡齿,从而大大提高了膨胀螺丝的固定性能。
Description
技术领域
本发明涉及一种日常用品,更确切地说,是一种膨胀螺套。
背景技术
膨胀螺丝一般说的是金属膨胀螺丝,膨胀螺丝之固定乃是利用楔形斜度来促使膨胀产生摩擦握裹力,达到固定效果。螺钉一头是螺纹,一头有锥度。外面包一铁皮(有的是钢管),铁皮圆筒(钢管)一半有若干切口,把它们一起塞进墙上打好的洞里,然后锁螺母,螺母把螺钉往外拉,将锥度拉入铁皮圆筒,铁皮圆筒被涨开,于是紧紧固定在墙上,一般用于防护栏、雨篷、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。
在膨胀螺钉的使用过程中,很多脱落的情况都是由于膨胀螺套不能很好地固定螺丝有关。
发明内容
本发明主要是解决现有技术所存在的技术问题,从而提供一种可以有效提高膨胀螺丝固定性能的膨胀螺套。
本发明的上述技术问题主要是通过下述技术方案得以解决的:
一种膨胀螺套,包含一第一膨胀筋和一第二膨胀筋,所述的第一膨胀筋上设有一第一卡齿, 所述的第二膨胀筋上设有一第二卡齿。
作为本发明较佳的实施例,所述的第一膨胀筋和第二膨胀筋上设有若干凹槽。
作为本发明较佳的实施例,所述的第一卡齿和第二卡齿相互对称。
由于本发明的膨胀螺套上设置了两个对称的卡齿,从而大大提高了膨胀螺丝的固定性能。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案,下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。
图1为本发明的膨胀螺套的立体结构示意图;
图2为图1中的膨胀螺套的立体结构示意图,此时为另一视角。
具体实施方式
下面结合附图对本发明的优选实施例进行详细阐述,以使本发明的优点和特征能更易于被本领域技术人员理解,从而对本发明的保护范围做出更为清楚明确的界定。
本发明提供了一种可以有效提高膨胀螺丝固定性能的膨胀螺套。
如图1、图2所示,一种膨胀螺套1,包含一第一膨胀筋21和一第二膨胀筋22,所述的第一膨胀筋21上设有一第一卡齿31, 所述的第二膨胀筋22上设有一第二卡齿32。
如图1、图2所示,所述的第一膨胀筋21和第二膨胀筋22上设有若干凹槽4。
如图1、图2所示,所述的第一卡齿31和第二卡齿32相互对称。
该发明的膨胀螺套上设置了两个对称的卡齿,从而大大提高了膨胀螺丝的固定性能。
以上仅仅以一个实施方式来说明本发明的设计思路,在***允许的情况下,本发明可以扩展为同时外接更多的功能模块,从而最大限度扩展其功能。
以上所述,仅为本发明的具体实施方式,但本发明的保护范围并不局限于此,任何不经过创造性劳动想到的变化或替换,都应涵盖在本发明的保护范围之内。因此,本发明的保护范围应该以权利要求书所限定的保护范围为准。
Claims (3)
1.一种膨胀螺套(1),包含一第一膨胀筋(21)和一第二膨胀筋(22),其特征在于,所述的第一膨胀筋(21)上设有一第一卡齿(31), 所述的第二膨胀筋(22)上设有一第二卡齿(32)。
2.根据权利要求1所述的膨胀螺套,其特征在于,所述的第一膨胀筋(21)和第二膨胀筋(22)上设有若干凹槽(4)。
3.根据权利要求2所述的膨胀螺套,其特征在于,所述的第一卡齿(31)和第二卡齿(32)相互对称。
