Abstract
一种紧固组件,包括螺栓和螺母,其特征在于:在螺栓的螺纹部分轴向开设有多个直线型凹槽,形成尖锐的防倒齿。在螺母的上端面上开设有阀室,在阀室内设有防松动阀,防松动阀的中心处和阀室的底面铰接,在阀室的上端面上设有弹簧,弹簧一端连接防松动阀的一端,另一端连接阀室底面上靠近内径的边缘。其优点在于:解决了普通螺栓和螺母旋紧不牢固,容易松动的缺陷,结构简单,价格低廉,便于大批量生产,可以手动控制螺母的旋紧和松动。
Description
技术领域
本发明属于机械领域,特别涉及一种紧固组件。
背景技术
螺栓为机械零件,配用螺母的圆柱形带螺纹的紧固件。由头部和螺杆(带有外螺纹的圆柱体)两部分组成的一类紧固件,需与螺母配合,用于紧固连接两个带有通孔的零件。这种连接形式称螺栓连接。如把螺母从螺栓上旋下,又可以使这两个零件分开,故螺栓连接是属于可拆卸连接。螺母就是螺帽,与螺栓或螺杆拧在一起用来起紧固作用的零件,所有生产制造机械必须用的一种元件根据材质的不同,分为碳钢、不锈钢、有色金属(如铜)等几大类型。
发明内容
本发明的目的是提供一种紧固组件,解决了普通螺栓和螺母旋紧不牢固,容易松动的缺陷,结构简单,价格低廉,便于大批量生产。
采用的技术方案是:
一种紧固组件,包括螺栓和螺母,其特征在于:
在螺栓的螺纹部分轴向开设有多个直线型凹槽,形成尖锐的防倒齿。
在螺母的上端面上开设有阀室,在阀室内设有防松动阀,防松动阀的中心处和阀室的底面铰接,在阀室的上端面上设有弹簧,弹簧一端连接防松动阀的一端,另一端连接阀室底面上靠近内径的边缘。
其优点在于:解决了普通螺栓和螺母旋紧不牢固,容易松动的缺陷,结构简单,价格低廉,便于大批量生产,可以手动控制螺母的旋紧和松动。
附图说明
图1是螺栓的结构示意图。
图2是螺母的结构示意图。
图3是本发明的俯视的结构示意图。
具体实施方式
一种紧固组件,包括螺栓1和螺母2,其特征在于:
在螺栓1的螺纹部分轴向开设有多个直线型凹槽3,形成尖锐的防倒齿4。
