Description

一种门牌钉
技术领域
本发明涉及一种门牌钉,尤其涉及固定木门门牌使用的门牌钉。
背景技术
企事业单位、宾馆、宿舍等房门上都需要使用门牌,现今的门牌采用钉子钉在门上,但是这种实施方式不牢靠,随着门的热胀冷缩,和人为使用(关门,开门)会造成钉子脱落,从而使得门牌掉落,这时原先在门上的钉孔又无法再次使用,需要重新打孔,不但损坏门,还影响美观。
发明内容
本发明的目的是解决门牌因长期使用导致脱落的问题。
本发明采用的技术方案是:一种门牌钉,包括中空的外钉和套接在外钉内的内钉,所述的外钉钉杆上设有刀孔,外钉内壁靠近刀孔的左侧固连有挡片;所述的内钉的钉杆上设有与刀孔相适配的刀片。
作为本发明的进一步改进,刀片为可伸缩刀片。
作为本发明的进一步改进,刀片的刀头两侧设有倒钩。
作为本发明的进一步改进,内钉长于外钉。
作为本发明的进一步改进,内钉与外钉螺纹连接。
本发明的有益效果是:当该钉进入门板内,刀片可弹出,刀片上设有倒刺,可以防止钉子脱落,延长门牌实用寿命,不会在门上留下多处孔洞,不影响美观。
附图说明
图1为本发明示意图。
图2为本发明内钉示意图。
图3为本发明外钉内壁刀孔处示意图。
图中所示:1外钉,2刀孔,3内钉,4刀片,5挡片。
具体实施方式
下面结合附图,对本发明具体实施方式作详细说明。
如图1和图3所示,本实施例包括中空的外钉1和套接在外钉1内的内钉3,外钉1钉杆上设有刀孔2,外钉1内壁靠近刀孔的左侧固连有挡片5;所述的内钉3的钉杆上设有与刀孔2相适配的刀片4,内钉3长于外钉1,内钉3与外钉1螺纹连接。
如图2所示,刀片4为可伸缩刀片,刀片4的刀头两侧设有倒钩。
先用螺丝刀将门牌钉好,因为外钉1内壁靠近刀孔的左侧固连有挡片5,所以可以保证刀片4不会从刀孔2伸出,钉3长于外钉1,在钉好门牌时,用螺丝刀将内钉3逆时针旋转,内钉3上升,刀片4会从刀孔2处弹出,这时内钉3无法用螺丝刀旋转;刀片4直接嵌进门内,又因刀片4的刀头两侧设有倒钩,所以保证门牌钉不会因开关门或震动而掉落。
以上结合附图对本发明的实施方式作了说明,但是本发明不限于上述实施方式,在所属技术领域普通技术人员所具备的知识范围内,还可以在不脱离本发明宗旨的前提下做出各种变化。
