Description

双保险半圆头方颈螺栓
技术领域:
本实用新型涉及一种螺丝钉,具体涉及一种双保险半圆头方颈螺栓。
背景技术:
螺栓在机械行业使用是很广泛的,圆头螺栓一般是固定在设备零部件的平面内,并穿过零部件,另一螺栓钉头用螺帽固紧。但在长期使用过程中,由于受外力或设备本身震动,使螺栓出现松动,或用扳手旋紧螺帽时会打转螺栓,严重时在造成重大安全隐患,给用户造成经济损失。
实用新型内容:
针对现有上述产品的技术不足,本实用新型的目的在于提供一种双保险半圆头方颈螺栓,其由半圆端头、螺颈、螺杆、销孔等组成。
本实用新型解决其技术问题所采用的技术方案是:半圆头端头、螺颈、螺杆为一体式结构,半圆头端头与螺杆连接处设计成直角结构,螺杆上段设有一节螺颈,螺颈上没有设置螺牙,螺颈是四方体形状;螺杆下段设置圆形螺牙,且各圆形螺牙呈同角度的排列,下段螺杆的螺杆钉头设有倒角,螺杆钉头下方0.5cm处设置销孔。
本实用新型的有益效果是:稳定、紧固时间寿命长、耐用,结构紧凑,实用效果好。
附图说明:
图1为本实用新型整体结构示意图;
图2为本实用新型半圆端头结构示意图;
图中,1、半圆端头2、螺颈3、螺杆4、销孔5、螺杆钉头
具体实施方式:
如图所示,本实用新型产品其由半圆端头1、螺颈2、螺杆3、销孔4、螺杆钉头5组成。整只螺栓插入设备零部件中,只有半圆端头1留在设备零部件的平面外,半圆端头1与螺杆3连接处设计成直角结构,螺杆3上段设有一节螺颈2,螺颈2上没有设置螺牙,螺颈2是四方体形状,容易卡住圆形螺栓孔,使螺栓稳定,在扳手旋紧螺帽,不会出现螺栓打转情况;螺杆3下段设置圆形螺牙,且各圆形螺牙呈同角度的排列,下段螺杆的螺杆钉头5设有倒角,螺杆钉头5下方设置销孔4与螺帽中孔配套,销钉插入螺帽中孔穿过销孔4,使螺栓紧固更好,对需紧固物体起到双保险作用,整体结构紧凑,操作更为省力,以提高实用效果。
