Abstract

本发明公开了一种弹簧拉钩,包括固定管(1)和弹簧(2),所述弹簧(2)的上端固定在固定管(1)的顶部,下端从固定管(1)内穿出,并与拉钩(3)连接,所述弹簧(2)收紧时位于固定管(1)内的部分上还设有一限位板(4)。本发明由于设置了限位板,在弹簧拉伸到一定程度之后,限位板会抵住固定管的底部,因此弹簧不会被彻底拉开,避免了被拉松。

Description

弹簧拉钩
技术领域
本发明涉及一种弹簧拉钩。
背景技术
现有的弹簧拉钩在拉力足够大的情况下,都能够将弹簧拉开,但若是弹簧经常被拉伸至最长,会导致弹簧被拉松。
发明内容
本发明为了解决目前弹簧拉钩上的弹簧容易被拉松的问题,为此提供了一种弹簧拉钩,包括固定管1和弹簧2,所述弹簧2的上端固定在固定管1的顶部,下端从固定管1内穿出,并与拉钩3连接,所述弹簧2收紧时位于固定管1内的部分上还设有一限位板4。
本发明弹簧拉钩,所述限位板4位于固定管1的上半部分内。
本发明有益效果是:
本发明由于设置了限位板,在弹簧拉伸到一定程度之后,限位板会抵住固定管的底部,因此弹簧不会被彻底拉开,避免了被拉松。
附图说明
本发明将通过例子并参照附图的方式说明,其中:
图1是本发明的示意图。
具体实施方式
本说明书中公开的所有特征,或公开的所有方法或过程中的步骤,除了互相排斥的特征和/或步骤以外,均可以以任何方式组合。
本说明书中公开的任一特征,除非特别叙述,均可被其他等效或具有类似目的的替代特征加以替换。即,除非特别叙述,每个特征只是一系列等效或类似特征中的一个例子而已。
如图1所示的弹簧拉钩,包括固定管1和弹簧2,所述弹簧2的上端固定在固定管1的顶部,下端从固定管1内穿出,并与拉钩3连接,所述弹簧2收紧时位于固定管1内的部分上还设有一限位板4,所述限位板4位于固定管1的上半部分内。本发明由于设置了限位板,在弹簧拉伸到一定程度之后,限位板会抵住固定管的底部,因此弹簧不会被彻底拉开,避免了被拉松。
本发明并不局限于前述的具体实施方式。本发明扩展到任何在本说明书中披露的新特征或任何新的组合,以及披露的任一新的方法或过程的步骤或任何新的组合。

Claims (2)

1.一种弹簧拉钩,其特征是:包括固定管(1)和弹簧(2),所述弹簧(2)的上端固定在固定管(1)的顶部,下端从固定管(1)内穿出,并与拉钩(3)连接,所述弹簧(2)收紧时位于固定管(1)内的部分上还设有一限位板(4)。
2.根据权利要求1所述的弹簧拉钩,其特征是:所述限位板(4)位于固定管(1)的上半部分内。
