Description

一种新型防松脱紧固件
技术领域
本实用新型涉及紧固件技术领域，具体是一种新型防松脱紧固件。 
背景技术
在紧固件技术领域，通过螺纹紧固件的连接是人们在日常生产和生活中常见的一种机械联接方式，由于螺纹的锁紧是由螺杆牙齿和螺母牙齿之间的摩擦力保证的，因而在轻载荷下和轻微振动下，他们之间不会产生相对移动，但是在重荷载下，特别是在交变载荷和横向的振动下，构件在工作时受到连续、频繁的振动，导致内外螺纹之间的间隙变大，使螺纹之间的摩擦力消失，造成了螺母的松脱，影响其使用寿命。 
发明内容
本实用新型所要解决的技术问题是提供一种安装方便，使用寿命长的新型防松脱紧固件。 
本实用新型是通过以下技术方案来实现的： 
本实用新型的一种新型防松脱紧固件，包括螺栓主体和螺母主体，所述螺母主体内设有通孔，所述螺栓主体下方设有螺杆，所述螺杆底端设有凸块，所述凸块上端连接有弹性立柱，所述弹性立柱设置在螺杆内部，所述螺杆顶部设有螺头，所述螺头底部两端设有弹片。
进一步地技术方案，所述螺杆上和通孔内均设有螺纹。 
进一步地技术方案，所述弹性立柱与螺杆之间设有间隙。 
本实用新型的有益效果是：本实施结构简单，使用寿命长，可靠性高，不易松脱，使用安全的紧固件，材料成本低。 
附图说明
为了易于说明，本实用新型由下述的具体实施例及附图作以详细描述。 
图1为本实用新型的一种新型防松脱紧固件结构示意图。 
具体实施方式
如图1所示，本实用新型的一种新型防松脱紧固件，包括螺栓主体2和螺母主体5，所述螺母主体5内设有通孔6，所述螺栓主体2下方设有螺杆3，所述螺杆3底端设有凸块4，所述凸块4上端连接有弹性立柱7，所述弹性立柱7设置在螺杆3内部，所述螺杆3顶部设有螺头1，所述螺头1底部两端设有弹片8。 
其中，所述螺杆3上和通孔6内均设有螺纹。 
所述弹性立柱7与螺杆3之间设有间隙。 
本实用新型的有益效果是：本实施结构简单，使用寿命长，可靠性高，不易松脱，使用安全的紧固件，材料成本低。 
    以上所述，仅为本实用新型的具体实施方式，但本实用新型的保护范围并不局限于此，任何不经过创造性劳动想到的变化或替换，都应涵盖在本实用新型的保护范围之内。因此，本实用新型的保护范围应该以权利要求书所限定的保护范围为准。
