Description

执行器螺钉防掉装置
所属技术领域:
[0001] 本实用新型涉及一种设备连接部件螺钉防掉装置,特别涉及一种执行器螺钉防掉
>J-U ρςα装直。
背景技术:
[0002] 电动执行机构接线时需要把端盖打开,打开端盖要拆卸与箱体连接的内六角螺钉,由于现场工况复杂,与箱体连接的内六角螺钉经常会掉了,很难找到,给用户带来不便。
实用新型内容:
[0003] 针对现有上述产品的技术不足,本实用新型的目的就是提供一种执行器螺钉防掉装置,由端盖、内六角螺钉、箱体等组成。
[0004] 本实用新型解决其技术问题所采用的技术方案是:内六角螺钉连接端盖与箱体,端盖螺钉孔的孔口部分加工一小段螺纹,内六角螺钉的螺杆颈端部有一小节没有设制螺牙,螺杆钉头部设有圆形螺旋状的螺牙,螺杆钉头部各圆形螺牙呈同角度的排列。
[0005] 本实用新型有益效果:结构简单,使用方便。
[0006] 说明附图:
[0007] 图1为本实用新型的结构示意图;
[0008] 图中,1、端盖,2、内六角螺钉,3、箱体。
具体实施方式:
[0009] 如附图1所示,本实用新型由端盖1、内六角螺钉2、箱体3组成,端盖I与箱体3连接用内六角螺钉2固定,端盖I螺钉孔的孔口部分加工一小段螺纹,内六角螺钉2的螺杆颈端部有一小节没有设制螺牙,螺杆 钉头部设有圆形螺旋状的螺牙,且各圆形螺牙呈同角度的排列,打开端盖I要拆卸与箱体3连接的内六角螺钉2,这样拆卸后的内六角螺钉2就留在端盖I上面了,使用方便。

Claims (2)

1.一种执行器螺钉防掉装置,由端盖、内六角螺钉、箱体组成,其特征在于:内六角螺钉连接端盖与箱体,端盖螺钉孔的孔口部分加工一小段螺纹,内六角螺钉的螺杆颈端部有一小节没有设制螺牙,螺杆钉头部设有圆形螺旋状的螺牙。
2.根据权利要求1所述的执行器螺钉防掉装置,其特征在于:所述的螺杆钉头部各圆形螺牙呈同角度的排列。
