Description
Technical Field
The utility model relates to a tool to lock field, concretely relates to be used as couple lock of two locks on door plant.
Background
On some heavier door plant of weight, especially the door that opens and shuts from top to bottom, if only set up one lock, then personnel are in the one-time of unblanking, and the door plant can be because the dead weight is too big fast downwardly rotating, causes personnel to pound the injury.
In the prior art, a simple hook lock is arranged on the door plate as a secondary lock, the hook lock is provided with a hook, and a baffle plate matched with the hook of the hook lock is arranged on a door frame; when the door panel is in a locking state, the hook of the hook lock is not contacted with the baffle on the door panel; when the first lock is opened, the door plate rotates downwards to a certain angle, the hook on the hook lock moves downwards along with the door plate and hooks the baffle on the door frame, so that the door plate cannot continuously fall, and the personnel are prevented from being injured by crashing; at the moment, a door gap is formed between the door plate and the door frame, and during unlocking, only a hand or a tool is required to extend into the door gap, and the hook lock is pulled open towards one side to enable the hook to be separated from the baffle plate, so that unlocking can be completed.
However, the hook lock has certain defects, the simple hook lock cannot stretch out and draw back, and in actual use, the situation that the gap between the baffle and the hook is not large enough to open the door seam exists, so that hands or tools cannot stretch into the hook lock, and the unlocking is difficult; the condition that the distance between the baffle and the hook is large can exist, when the door plate falls to reach a high speed, the hook can hook the baffle, the hook or the baffle is impacted greatly, and the service life of the hook lock is greatly shortened.
If the retractable hook lock is designed, the hook can be always hooked on the baffle due to the elastic connection between the hook and the door panel during unlocking, and inconvenience is brought to unlocking.
Therefore, how to solve the above-mentioned deficiencies of the prior art is a problem to be solved by the present invention.
