An anti-unhooking device attached to a lifting hook comprises a mounting part, an anti-unhooking stop lever and an anti-reverse part and is used for rotatably attaching the anti-unhooking device to the lifting hook. The mounting part comprises a clamping device and pivots, the clamping device is fixedly connected with the neck of the lifting hook along a clamping axis, and the pivots are perpendicular to the clamping axis and are integrally connected to the two sides of the clamping device; the anti-reverse-rotation part is in coupling connection with the anti-disengagement stop lever, and the anti-reverse-rotation part enables the anti-disengagement stop lever to hinder reverse rotation of the posture of converting the hook opening closing posture into the hook opening opening posture and not hinder forward rotation of the posture of converting the hook opening opening posture into the hook opening closing posture, so that normal closing is achieved, accidental opening is avoided forever, and great practical value is achieved.
一种附接到吊钩的防脱钩装置,包括安装部、防脱挡杆和防反转部,用于将防脱钩装置可旋转地附接到吊钩;安装部包括夹紧器和枢轴,夹紧器沿夹紧轴线固定连接吊钩颈部,枢轴垂直于夹紧轴线一体连接于夹紧器两侧;防反转部耦合连接防脱挡杆,防反转部使得防脱挡杆阻碍由闭合钩口姿态转变为打开钩口姿态的姿态反转,而不阻碍由打开钩口姿态转变为闭合钩口姿态的姿态正转实现了常态闭合,永不意外打开,有很大的实用价值。
