Abstract

本实用新型公开了一种双头螺钉,包括螺柱,所述螺柱的另一端为自攻螺钉杆,螺柱与自攻螺钉杆之间设置径向通孔,径向通孔中过盈的装入定位杆,螺柱头上设置有“一”字或者“十”字槽。本实用新型可以用于替代预埋在塑料件中的螺钉嵌件,采用后续工艺安装双头螺钉,简化模具,提高生产效率,塑料件镀铬时,简化镀铬工艺,在螺钉丝牙损坏的情况下,可以替换该螺钉。

Description

双头螺钉
技术领域
本实用新型涉及紧固件,尤其是用于预埋在塑料件中的双头螺钉。
背景技术
塑料制品由于其强度较低,螺栓连接的地方经常采用螺钉嵌件预埋在塑料件中的方式,具有连接牢固的优点,但是,预埋位置比较固定,调整不方便,且模具成本较高、螺钉损坏时更换困难。
实用新型内容
本实用新型的目的是提供一种双头螺钉,替代预埋在塑料件中的螺钉嵌件,采用后续工艺安装双头螺钉,简化模具。
为了达到上述目的,本实用新型的双头螺钉,包括螺柱,所述螺柱的另一端为自攻螺钉杆,螺柱与自攻螺钉杆之间设置径向通孔,径向通孔中过盈的装入定位杆,螺柱头上设置有“一”字或者“十”字槽。
本实用新型可以用于替代预埋在塑料件中的螺钉嵌件,采用后续工艺安装双头螺钉,简化模具,提高生产效率,塑料件镀铬时,简化镀铬工艺,在螺钉丝牙损坏的情况下,可以替换该螺钉。
附图说明
下面结合附图和实施例对本实用新型作进一步说明。
图1是本实用新型的双头螺钉结构示意图;
图2是图1的左视图。
具体实施方式
图1、图2中,本实用新型的双头螺钉,包括螺柱1,螺柱1是普通螺纹,用于螺栓连接,螺柱1的另一端为自攻螺钉杆2,自攻螺钉杆2是锥螺纹,自攻螺钉杆2在后续工艺安装双头螺钉到塑料件上提供方便,同时,螺柱1头上设置有“一”字槽4,用螺丝刀可以方便的安装,“一”字槽4也可以设置成“十”字槽,螺柱1与自攻螺钉杆2之间设置了径向通孔5,径向通孔5中过盈的装入定位杆3,定位杆3限制自攻螺钉杆2的最终拧入深度,以保证外留的螺柱1的设计长度。

Claims (1)
