The specific using process is as follows:
under the condition that no fire occurs, the rotating block 47 and the outer circle inner square sleeve 50 in the manual unlocking system of the movable bolt can not rotate together, the rotating block 47 is fixedly connected with the outdoor handle 2, the outer circle inner square sleeve 50 is fixedly connected with the power transmission rod 3, and the rotating block 47 and the outer circle inner square sleeve 50 are not fixed, so that the movable bolt can not be unlocked by the outdoor handle 2 under the normal condition.
When a fire disaster happens, the manual unlocking system of the movable bolt receives a signal and automatically starts the function, and the outdoor handle 2 controls the power transmission rod 3 to unlock.
When a fire disaster occurs and the manual unlocking system of the movable bolt receives a signal, the automatic control motor 42 rotates to drive the screw rod 44 to rotate, the screw rod 44 drives the push block 45 to move forward or backward, so as to drive the ejector pin 48 associated with the push block 45 to move, the ejector pin 48 moves to push the bolt 49 to move to be combined with the outer circle inner square sleeve 50, at the moment, the bolt 49 is connected with the outer circle inner square sleeve 50 and the rotating block 47 into a whole, and when the outdoor handle 2 connected with the rotating block 47 rotates manually, the rotating block 47, the bolt 49 and the outer circle inner square sleeve 50 are driven to rotate together, so as to drive the power transmission rod 3 connected with the outer circle inner square sleeve 50 to rotate together, and finally, the movable bolt (oblique bolt) is driven to retract to realize unlocking.
The working conditions of the existing full-automatic electronic anti-theft lock are as follows: indoor handle 1 drives indoor quick-open handle connecting seat 5 synchronous revolution through the mode of manual rotatory indoor handle 1 to drive and rotate together with the power transmission pole 3 that indoor quick-open handle connecting seat 5 links to each other, the rotatory movable spring bolt withdrawal that drives of power transmission pole 3 at last. When the hand stops exerting strength, the movable bolt resets, and the power conduction pole 3 resets is also driven to the power of the automatic reset of the spring in the movable bolt, and the power conduction pole 3 resets for reset through the indoor handle 1 that links to each other with indoor quick-open handle connecting seat 5.
The existing full-automatic electronic anti-theft lock has no handle or other device for opening the movable bolt.
On the basis of the existing full-automatic electronic anti-theft lock, the mechanical connection relationship between the unlocking device 4 and the outdoor handle 2 and the mechanical connection relationship between the outdoor handle 2 and the unlocking device 4 are added, so that the power transmission rod 3 can be controlled through the outdoor handle 2, and finally, the purpose of unlocking the movable bolt outdoors under the condition of fire is achieved.
The unlocking process is realized through the outdoor handle 2 as follows:
when no fire signal is sent, the bolt 49 is disconnected with the outer circle inner square sleeve 50, the bolt 49 is inserted into the pin seat 46, namely the bolt 49 connects the pin seat 46 and the rotating block 47 together, and the outdoor handle 2 is fixed and cannot rotate. At this time, the pin seat 46, the bolt 49 and the rotating block 47 are fixed into a whole, the pin seat 46 is fixed on the bottom plate 41, the bottom plate 41 is locked on the shell to be a fixing part, and finally the outdoor handle 2 fixed with the rotating block 47 is fixed, so that the purpose that the outdoor handle 2 cannot unlock the movable bolt under normal conditions is achieved, and meanwhile, the movable bolt cannot rotate to ensure that functions such as misoperation cannot be caused. When a fire signal is generated, the motor 42 rotates to drive the screw rod 44 to rotate, the screw rod 44 drives the pushing block 45 to displace and push against the ejector pin 48, the ejector pin 48 pushes the bolt 49 out of the pin seat 46, but the ejector pin 48 cannot go out of the range of the pin seat 46. At this moment, after the bolt 49 is ejected out, the bolt 49 is inserted into the outer circle inner square sleeve 50, the rotating block 47 and the outer circle inner square sleeve 50 are connected together through the bolt 49, the handle which is connected with the rotating block 47 outdoors can be rotated, the outdoor handle 2 is rotated to drive the rotating block 47 to rotate, so that the outer circle inner square sleeve 50 is driven, the power transmission rod 3 is driven to rotate, and finally the power transmission rod 3 rotates to drive the movable bolt in the lock body to retract, so that the purpose of opening the door is achieved.
When the hands of people do not act on the outdoor handle 2, the movable bolt automatically resets under the action of the spring force of the spring arranged in the movable bolt, and the movable bolt extends out. At the same time, the power transmission rod 3 is also simultaneously reset together, so that the outer circle and the inner square sleeve 50 are reset. At the moment, the outdoor handle 2 can circularly open the movable bolt for many times, so that the opening of the rescue evacuation channel cannot be influenced by the opening of the movable bolt under the condition of fire, and the fire rescue evacuation function is realized.
After fire or rescue is relieved, the full-automatic electronic anti-theft lock recovers normal work, a fire-fighting reset key is pressed, the motor 42 automatically starts to rotate after receiving a fire-fighting reset signal, the screw 44 is driven to rotate, the push block 45 moves backwards, the bolt 49 is reset through the spring (the spring is arranged at the step of the pin hole 474 in fig. 9, the spring is compressed when the bolt 49 extends into the rotating block 47, the bolt 49 is automatically popped out by the spring to realize reset after the push block 45 moves backwards, the bolt 49 can push the ejector pin 48 to reset in the process of retreating, after the bolt 49 is reset, one part of the bolt is in the pin seat 46, and the other part of the bolt is in the rotating block 47, so that the outdoor handle 2 is fixed and cannot be used, the movable bolt cannot be unlocked, and the normal anti-theft function of the full-automatic electronic anti-theft lock is not influenced under normal conditions.
