Abstract

本实用新型公开一种防寒、耐高温防盗螺母,在螺母(2)的螺纹孔的内壁上设有径向“C”形槽(6),在“C”形槽(6)的槽底面处设有轴向柱(5),轴向柱(5)与螺母(2)连为一体,在“C”形槽(6)内设有弹簧(4)和钢珠(3),弹簧(4)和钢珠(3)在轴向柱(5)旋进方向一侧,弹簧(4)在钢珠(3)与轴向柱(5)之间,当螺栓到达“C”形槽(6)处时,螺栓的螺纹带动钢珠(3)压缩弹簧(4),使钢珠(3)处于低位,不影响螺母(2)的旋进,当螺母(2)反向旋出时,钢珠(3)在弹簧(4)的弹力作用下处于高位,阻止螺母(2)的旋出,起到防盗作用。是一种无论是在寒冷的冬季还是在火烧的情况下,均不能旋出,始终能够起到防盗作用的防盗螺母。

Description

防寒、耐高温防盗螺母
技术领域
本实用新型涉及一种防盗螺母,尤其是一种防寒、耐高温防盗螺母。
背景技术
目前,市售的防盗螺母的“C”形槽内用胶固定有橡胶弹簧挡块,即相当于本实用新型的“轴向柱”。橡胶弹簧挡块在寒冷的冬季会***发脆,用力旋动螺母,橡胶弹簧挡块会变成碎块,从而使螺母失去防盗作用;橡胶弹簧挡块在遇到高温使会***,同样能够使螺母失去防盗作用。因此,设计一种防寒、耐高温防盗螺母,是目前需要解决的技术问题。
发明内容
本实用新型所要解决的技术问题是提供一种防寒、耐高温防盗螺母。
本实用新型解决其技术问题的技术方案是:
防寒、耐高温防盗螺母,在螺母的螺纹孔的内壁上设有径向“C”形槽,在“C”形槽的槽底面处设有轴向柱,轴向柱与螺母连为一体,在“C”形槽内设有弹簧和钢珠,弹簧和钢珠在轴向柱旋进方向一侧,弹簧在钢珠与轴向柱之间,当螺栓到达“C”形槽处时,螺栓的螺纹带动钢珠压缩弹簧,使钢珠处于低位,不影响螺母的旋进,当螺母反向旋出时,钢珠在弹簧的弹力作用下处于高位,阻止螺母的旋出,起到防盗作用。
优选地,在螺母的螺纹孔内套装有胶塞,当螺母旋进螺栓上时,螺栓逐步将胶塞顶出,方便安装。
与现有技术相比,本实用新型无伦是在寒冷的冬季还是在火烧的情况先,均不能旋出,始终能够起到防盗作用;又由于设有胶塞,容易形成成套产品,不但便于经营,而且方便安装。
附图所示
图1是本实用新型的结构示意图的主视图(剖视图);
图2是图1的A-A向剖面图。
具体实施方式
如图所示,防寒、耐高温防盗螺母,在螺母2的螺纹孔的内壁上设有径向“C”形槽6,在“C”形槽6的槽底面处设有轴向柱5,轴向柱5与螺母2连为一体,在“C”形槽6内设有弹簧4和钢珠3,弹簧4和钢珠3在轴向柱5旋进方向一侧,弹簧4在钢珠3与轴向柱5之间,当螺栓到达“C”形槽6处时,螺栓的螺纹带动钢珠3压缩弹簧4,使钢珠3处于低位,不影响螺母2的旋进,当螺母2反向旋出时,钢珠3在弹簧4的弹力作用下处于高位,阻止螺母2的旋出,起到防盗作用。
在螺母2的螺纹孔内套装有胶塞1。
加工时,首先从螺母的顶端向“C”形槽处钻轴向盲孔,使轴向盲孔轴向穿过“C”形槽,然后将加工好的轴向柱放进轴向盲孔内,再将轴向盲孔封堵。

Claims (2)
