Safety lock for high-altitude operation safety device driven by clip and slot

Abstract

The invention discloses a safety lock utilizing drive fastening of a fastener and a fastening groove and used for a high-altitude operation safety device. The safety lock structurally comprises a lockbody, a control device, and a rope tying hole, wherein the rope tying hole is formed in the tail end of the lock body and penetrates through the lock body, the control device is arranged in an innercavity of the lock body, and the control device is in mechanical fit with the lock body. The safety lock has the beneficial effects that a spiral block is rolled through manually rolling to drive a threaded strip plate to ascend or descend so as to realize the aim that the fastener can ascend and descend along with the threaded strip plate to change between a state in which the fastener is fastened into a fastening groove structure or a state in which the fastener is separated from the fastening groove structure correspondingly, unlocking or locking of the safety lock is realized, so that thepotential safety hazard caused by the fact that an elastic element of the traditional safety lock is prone to damage and even loosens are avoided; and through utilizing the effects of the fixed lengthof a connecting line and the gravity of a pushing block, a movable fastening rod is pushed to move towards the retracting direction of a spring, so that rectangular protrusions on the movable fastening rod are fastened in protrusions on the fastener, and thereby greatly increasing biting force between a fastener head and the fastening groove structure and improving the safety coefficient of the safety lock.

Description

technical field [0001] The invention relates to the field of high-altitude operation safety devices, in particular to a safety lock for high-altitude operation safety devices which uses a clip and a slot to drive and engage. Background technique [0002] In the process of working at heights, in order to further protect the safety of the workers, the workers must wear a safety rope. The safety rope and the safety device are often connected through a safety lock, thereby improving the safety factor of the workers working at heights. Now Some high-altitude work safety devices have the following defects: [0003] Safety locks generally use elastic elements to snap back and forth to achieve the change of the open or closed state of the safety lock. However, after long-term use, the working state of the elastic elements is frequently replaced, which is likely to cause damage or even loosening of the elastic elements, resulting in the failure of the safety lock. There is a gap whe...

[0003] Safety locks generally use elastic elements to snap back and forth to achieve the change of the open or closed state of the safety lock. However, after long-term use, the working state of the elastic elements is frequently replaced, which is likely to cause damage or even loosening of the elastic elements, resulting in the failure of the safety lock. There is a gap when it is opened or closed normally, which poses a safety hazard
