Abstract

本实用新型公开一种紧固件,包括螺栓、螺母,所述螺栓包括螺栓头、螺杆及螺纹体;所述螺母沿轴线开有一中心通孔,通孔一端加工成内六角,另一端设置为与螺纹体相配合的细牙螺纹,螺母外表面设置为粗牙螺纹。本实用新型的螺母外表面为粗牙螺纹,螺纹旋合接触面大,其与物体接触面紧固性好,使用的时候先用内六角扳手把螺母紧固到物体内,然后螺栓穿过另一物体后与螺母旋紧,从而拉紧式紧固实现两物体的锁紧。

Description

一种紧固件
技术领域
本实用新型涉及一种机械紧固件。
背景技术
目前,市场上的螺钉、螺栓,以直接配六角螺母等为主,这种连接方式,使用在夹紧紧固的部位完全没有问题,但如果使用在拉紧式紧固的部位,即实现两物体的拉紧式锁紧则无法使用。
发明内容
本实用新型的目的在于提供一种紧固件,能够较好的实现两个物体间的锁紧,紧固性好。
本实用新型的技术方案:一种紧固件,包括螺栓、螺母,所述螺栓包括螺栓头、螺杆及螺纹体;所述螺母沿轴线开有一中心通孔,通孔一端加工成内六角,另一端设置为与螺纹体相配合的细牙螺纹,螺母外表面设置为粗牙螺纹。
本实用新型的螺母外表面为粗牙螺纹,螺纹旋合接触面大,其与物体接触面紧固性好,使用的时候先用内六角扳手把螺母紧固到物体内,然后螺栓穿过另一物体后与螺母旋紧,从而拉紧式紧固实现两物体的锁紧。
附图说明
图1为本实用新型螺栓的结构示意图。
图2为本实用新型螺母的结构示意图。
图3为本实用新型锁紧两物体的示意图。
具体实施方式
如图1、2,一种紧固件,包括螺栓8、螺母1,所述螺栓8包括螺栓头7、螺杆6及螺纹体5,螺栓头7为标准头部梅花槽,螺纹体5为细牙螺纹;所述螺母1沿轴线开有一中心通孔,通孔一端加工成内六角4,另一端设置为与螺纹体5相配合的细牙螺纹3,螺母1外表面设置为粗牙螺纹2。
如图3,使用的时候,先用内六角扳手把螺母1紧固到物体A内,然后螺栓8穿过另一物体B,螺纹体5插入到螺母1内,拧动螺栓头7从而拉紧式紧固实现两物体的锁紧。螺母1外表面的粗牙螺纹旋合接触面大,其与物体接触面紧固性好。
