Abstract

本发明涉及固定连接件技术领域,具体涉及一种螺钉,包括螺杆,固定设置于螺杆一端的螺帽,螺杆的另一端为锥形端,所述螺帽的外径是螺杆外径的3倍—4倍,所述螺帽上开设有十字型槽口,在十字型槽口中装配有具有十字型旋动槽的旋动块。将螺帽的外径设置成螺杆外径的3至4倍,这样在旋动螺钉时,很容易将螺杆旋进工件中,同时采用具有十字型旋动槽的旋动块装配于螺帽上的十字型槽口中,这样在十字型旋动槽损坏后,只要将旋动块更换即可,继续进行操作,节省螺钉,便于对工件的装拆。

Description

一种螺钉
技术领域
[0001] 本发明涉及固定连接件技术领域,具体涉及一种螺钉。
背景技术
[0002] 在日常生活中,需要采用螺钉对需要固定的工件进行连接,现有的螺钉在安装时,由于螺帽尺寸不大,在旋转时,费力,不容易旋紧,且旋动槽是开设在螺帽上,这样在旋动槽损坏后,无法旋紧螺钉,导致该螺钉的报废,同时也不便于对工件的装拆。
发明内容
[0003] 针对上述技术问题,本发明提供一种螺钉,便于将螺钉旋紧,在旋紧槽损坏后,还可以更换继续旋动螺钉,便于对工件的装拆。
[0004] 实现本发明的技术方案如下:
[0005] 一种螺钉,包括螺杆,固定设置于螺杆一端的螺帽,螺杆的另一端为锥形端,所述螺帽的外径是螺杆外径的3倍一4倍,所述螺帽上开设有十字型槽口,在十字型槽口中装配有具有十字型旋动槽的旋动块。
[0006] 所述旋动块的高度低于或等于十字型槽口的深度。
[0007] 采用了上述方案,将螺帽的外径设置成螺杆外径的3至4倍,这样在旋动螺钉时,很容易将螺杆旋进工件中,同时采用具有十字型旋动槽的旋动块装配于螺帽上的十字型槽口中,这样在十字型旋动槽损坏后,只要将旋动块更换即可,继续进行操作,节省螺钉,便于对工件的装拆。
附图说明
[0008] 图1为本发明的结构示意图;
[0009] 图2为图1的俯视结构示意图;
具体实施方式
[0010] 下面结合附图和具体实施例对本发明进一步说明。
[0011] 参见图1、2,一种螺钉,包括螺杆1,固定设置于螺杆一端的螺帽2,螺杆的另一端为锥形端3,螺帽的外径是螺杆外径的3倍一4倍,螺帽上开设有十字型槽口 4,在十字型槽口中装配有具有十字型旋动槽5的旋动块6。为了旋动块装入十字槽口中不会滑出且容易受力,旋动块的高度低于或等于十字型槽口的深度。旋动块为与十字型槽口相应的十字型。

Claims (2)

1.一种螺钉,包括螺杆,固定设置于螺杆一端的螺帽,螺杆的另一端为锥形端,其特征在于,所述螺帽的外径是螺杆外径的3倍一4倍,所述螺帽上开设有十字型槽口,在十字型槽口中装配有具有十字型旋动槽的旋动块。
2.根据权利要求1所述的一种螺钉,其特征在于,所述旋动块的高度低于或等于十字型槽口的深度。
