Abstract

本发明涉及固定连接件技术领域,具体涉及一种连接牢固的螺钉,包括具有外螺纹的螺杆,固定于螺杆一端的螺帽,在螺帽上开设有旋槽,所述螺帽上沿螺杆的轴线方向开设有两个让位孔,以及插入上述让位孔中的侧边锁紧螺钉。在对工件连接时,先有螺杆插入工件中进行固定连接,然后再将两个侧边锁紧螺钉通过让位孔旋进工件中,这样能够保证工件之间的连接牢固性,长时间使用也不会出现工件间松动现象。

Description

一种连接牢固的螺钉
技术领域
本发明涉及固定连接件技术领域,具体涉及一种连接牢固的螺钉。
背景技术
在日常生活中,需要采用螺钉对需要固定的工件进行连接;现有的螺钉包括螺杆、螺帽以及锥形旋进端,在对两工件进行固定连接时,连接不牢固,容易出现松动现象。
发明内容
针对上述技术问题,本发明提供一种连接牢固的螺钉,其可以将工件之间牢固的连接,保证工件间的连接牢固性。
实现本发明的技术方案如下:
一种连接牢固的螺钉,包括具有外螺纹的螺杆,固定于螺杆一端的螺帽,在螺帽上开设有旋槽,所述螺帽上沿螺杆的轴线方向开设有两个让位孔,以及插入上述让位孔中的侧边锁紧螺钉。
所述让位孔为让位台阶孔,让位台阶孔的台阶面对侧边锁紧螺钉的螺帽形成支承。
所述侧边锁紧螺钉的长度为上述螺杆长度的1/3至1/2。
采用了上述方案,在对工件连接时,先有螺杆插入工件中进行固定连接,然后再将两个侧边锁紧螺钉通过让位孔旋进工件中,这样能够保证工件之间的连接牢固性,长时间使用也不会出现工件间松动现象。
附图说明
图1为本发明的结构示意图;
具体实施方式
下面结合附图和具体实施例对本发明进一步说明。
参见图1,一种连接牢固的螺钉,包括具有外螺纹1的螺杆2,固定于螺杆一端的螺帽3,螺杆的另一端为锥形旋进端4,在螺帽上开设有旋槽5,用于起子端部的插入进行旋转,螺帽上沿螺杆的轴线方向开设有两个让位孔6,以及一一对应插入上述让位孔中的两个侧边锁紧螺钉7。具体实施中,让位孔为让位台阶孔,让位台阶孔的台阶面8对侧边锁紧螺钉的螺帽9形成支承,这样防止侧边锁紧螺钉到位后还继续下降;侧边锁紧螺钉的长度为上述螺杆长度的1/3至1/2。

Claims (3)

1.一种连接牢固的螺钉,包括具有外螺纹的螺杆,固定于螺杆一端的螺帽,在螺帽上开设有旋槽,其特征在于,所述螺帽上沿螺杆的轴线方向开设有两个让位孔,以及插入上述让位孔中的侧边锁紧螺钉。
2.根据权利要求1所述的一种连接牢固的螺钉,其特征在于,所述让位孔为让位台阶孔,让位台阶孔的台阶面对侧边锁紧螺钉的螺帽形成支承。
3.根据权利要求1所述的一种连接牢固的螺钉,其特征在于,所述侧边锁紧螺钉的长度为上述螺杆长度的1/3至1/2。
