一种组合螺丝,包括一第一螺丝及一较所述第一螺丝规格较小的第二螺丝,所述第一螺丝上开设有一收容孔,所述第二螺丝收容于所述收容孔内并与所述第一螺丝锁合在一起。所述组合螺丝可为机构设备提供备用螺丝。

Description

组合螺丝
技术领域
本发明涉及一种螺丝,特别涉及一种组合螺丝。
背景技术
螺丝是许多机构设备中最基本的组件之一,许多机构设备在组装零件时,都需要使用至少两种专用型号的螺丝,以将分离的零件固定在一起。例如,在电脑以及服务器的机箱内,通常具有很多规格大小不同的螺丝,用以固定散热器,主板,硬盘,光驱以及扩展卡等不同组件,而小规格的螺丝因为体积小等原因很容易丢失,当使用者或者维修人员在拆装电脑以及服务器时,经常因为小规格螺丝的丢失而无专用的备用螺丝,造成维护的困扰。
发明内容
鉴于以上内容,有必要提供一种组合螺丝,在小规格螺丝丢失时可及时找到相同规格的备用螺丝。
一种组合螺丝,包括一第一螺丝及一较所述第一螺丝规格较小的第二螺丝,所述第一螺丝上开设有一收容孔,所述第二螺丝收容于所述收容孔内并与所述第一螺丝锁合在一起,所述第一螺丝包括一第一螺帽及一外表面切削有螺纹的第一螺杆,所述第一螺帽及第一螺杆连为一体,所述第二螺丝包括一第二螺帽及一外表面切削有螺纹的第二螺杆,所述第二螺帽及第二螺杆连为一体,所述收容孔自所述第一螺帽延伸至所述第一螺杆内,所述收容孔在所述第一螺帽内的部分用于收容所述第二螺帽,所述收容孔在所述第一螺杆内的部分用于收容所述第二螺杆,所述第一螺帽的上表面上沿所述收容孔外围对称开设有两沟槽,所述第二螺帽的中心处开设有相互对应的两沟槽,所述第二螺帽上的每一沟槽与所述第一螺帽上对应的一沟槽相连通。
一种组合螺丝,包括一第一螺丝及一较所述第一螺丝规格较小的第二螺丝,所述第一螺丝上开设有一收容孔,所述第一螺丝包括一第一螺帽及一外表面切削有螺纹的第一螺杆,所述第一螺帽及第一螺杆连为一体,所述第二螺丝包括一第二螺帽及一外表面切削有螺纹的第二螺杆,所述第二螺帽及第二螺杆连为一体,所述收容孔自所述第一螺帽延伸至所述第一螺杆内,所述收容孔在所述第一螺帽内的部分用于收容所述第二螺帽,所述收容孔在所述第一螺杆内的部分用于收容所述第二螺杆,所述第一螺帽的上表面上沿所述收容孔外围对称开设有两沟槽,所述第二螺帽的中心处开设有相互对应的两沟槽,所述第二螺帽上的每一沟槽与所述第一螺帽上对应的一沟槽相连通,当所述第二螺丝收容锁合于所述收容孔内可作为备用螺丝,所述第二螺丝从所述收容孔取出可单独使用。
所述组合螺丝中的第二螺丝既可锁合在所述第一螺丝中以备急需,也可从所述第一螺丝中取出单独使用,避免了当丢失小规格的螺丝时而找不到相同规格的备用螺丝的麻烦。
附图说明
图1是本发明组合螺丝较佳实施方式的立体分解图。
图2是本发明组合螺丝较佳实施方式的立体组合图。
图3是沿图2中III-III线的剖面图。
具体实施方式
下面结合附图及较佳实施方式对本发明作进一步详细描述:
请参照图1、图2及图3,本发明组合螺丝的较佳实施方式包括一第一螺丝10及一第二螺丝20。所述第一螺丝10为一大规格的螺丝,所述第二螺丝20为一小规格的螺丝,所述第一螺丝10包括一螺帽12及一外表面切削有螺纹的螺杆14,所述螺杆14与所述螺帽12连为一体。所述第二螺丝20包括一螺帽22及一外表面切削有螺纹的螺杆24,所述螺杆24与所述螺帽22连为一体,本实施方式中,所述螺帽12及14大致为圆锥状,所述第二螺丝20较所述第一螺丝10的尺寸小。
所述第一螺丝10内设有一收容孔16,所述收容孔16自所述螺帽12延伸至所述螺杆14内,所述收容孔16在所述螺帽12内的部分大致呈圆锥状,可收容第二螺丝20的螺帽22,所述收容孔16在螺杆14内的部分设有螺纹,可旋转锁合第二螺丝20的螺杆24。所述螺帽12的上表面上沿所述收容孔16的外围对称开设有两沟槽122,本实施方式中,当第二螺丝20旋转锁合于第一螺丝10时,所述收容孔16与所述第一螺丝10的中心轴互相重合,一螺丝刀伸入所述两沟槽122可旋转锁合第一螺丝10。
所述第二螺帽22的中心处开设有两两对应并相互连通成十字形的缺槽222及沟槽224,当所述第二螺丝20作为一备用螺丝时,其通过所述螺杆24上的螺纹锁合于所述第一螺丝10的收容孔16内,当所述第一、第二螺丝10及20锁合在一起时,所述螺杆24收容于所述收容孔16在所述螺杆14内的部分,所述螺帽22收容于所述收容孔16在所述螺帽12内的部分,每一沟槽122与一对应的沟槽224相连通,因此,使用一尺寸较大的螺丝刀伸入沟槽122及224可旋转锁合所述第一螺丝10,无需取出所述第二螺丝20。
当需要单独使用所述第二螺丝20时,可使用一尺寸较小的螺丝刀伸入沟槽224,从所述第一螺丝10中旋转地取出所述第二螺丝20。
因此,当机构设备中的第二螺丝20,即较小规格的螺丝丢失时,可从所述第一螺丝10中取出所述第二螺丝20来使用,为所述机构设备的后续维护带来方便。
