Detailed ways

The present invention is further described in conjunction with Fig. 1-Fig. 6:

The mechanical unlocking mechanism in an emergency includes a door body, a trigger mechanism component, and a modified lock component. Both the trigger mechanism assembly and the retrofit lock assembly are secured to the door body. When the trigger block 10 in the trigger mechanism assembly is pressed, the trigger mechanism assembly will be triggered, and the mechanical movement will be transmitted to the refit lock assembly through the connecting rod 7 . The modified lock assembly usually has the function of opening and closing the lock normally, and it will be opened by mechanical trigger in an emergency.

The trigger mechanism assembly is composed of a trigger block 10 , a linkage base 11 , a trigger power spring 12 , a linkage 8 , a trigger block base 9 and a connecting rod 7 that is pulled laterally. The trigger block 10 can slide up and down in the cylindrical groove on the linkage base 11, and cannot rotate. The linkage base 11 is fixed on the door body 1 with screws through three through holes; the linkage 8 is fixed on the trigger block base 9, and can rotate around the cylindrical protrusion on the trigger block base 9, one end of the linkage piece 8 is connected with the connecting rod 7, and the connecting rod 7 can freely rotate around the rotating shaft on the linkage piece 8, and the other end of the linkage piece 8 The protrusion 18 is in contact with the small protrusion 17 on the trigger block 10; one end of the trigger power spring 12 is connected to the linkage 8, and the other end is connected to the door body, and the trigger power spring 12 is in a tensioned state. When the trigger block 10 is pressed, the large protrusion 18 on the linkage 8 loses the blocking of the small protrusion 17 on the trigger block, and rotates counterclockwise around the cylindrical protrusion on the trigger block base 9 under the pulling force of the trigger power spring 12 , thereby driving the connecting rod 7 to move to the right. The trigger block 10, the trigger block base 9, the linkage 8 and the linkage base 11 are all made of hard steel. The installation direction of the trigger power spring 12 is along the tangential direction of the linkage 8, and spring steel is used as the material, and the length is about 0.08 meters. The middle part of the connecting rod 7 is made of tensile steel, and the two ends are made of hard steel. The total length of the connecting rod 7 is about 0.3 meters, and the direction is roughly horizontal.

The modified lock assembly is composed of a lock block fixture 14, a lock core 15, a lock block 16, a lock block slider 2, a lock block trigger 3, a small spring 4, a fixed part 5, a limit slide 6, a connecting rod 7 and a transverse The large spring 13 of stretching constitutes. The lock block fixture 14 is fixed on the door body by 4 screws; the lock block 14 is fixed with a lock core 15, and the lock core 15 can rotate after inserting the key under normal conditions, and the raised lock block protrusion 29 on the lock block 15 Push the lock block sliding assembly 2 to slide up and down in the chute in the lock block 16, the material of the lock core 15 is copper, and the material of the door body 1 and the lock block fixing part 14 is steel. The large spring 13 is respectively fixed on the door body 1 and the lock block 16 by pins. The large spring 13 is in a tensioned state, and the lock block 16 can be pulled laterally to the right to slide in the two transverse cylindrical grooves on the door body 1 to realize unlocking. Function. Big spring 13 material is spring steel, and length is about 0.08 meter, is installed horizontally along the sliding direction of lock block 16. The fixing part 5 and the locking block 16 are welded together without relative movement. The materials of the fixing part 5 and the locking block 16 are all steel. The locking block triggering part 3 slides in the long hole 20 on the fixing part 5 , the diameter of the long hole 20 is about 0.015 meters, and the direction of the long hole 20 is the same as the sliding direction of the locking block sliding part 2 . The small spring 4 is sleeved on the triggering piece 3 of the locking block, and the two ends of the small spring 4 are against the boss 26 and the fixing piece 5 on the triggering piece 3 of the locking block respectively. The small spring 4 is under pressure during normal state, and the material is spring steel, the static length is about 0.05 meters, and the length after being compressed is about 0.02 meters. The lock block slider protrusion 23 on the lock block slider 2 can slide in the short slide groove 24 on the lock block trigger member 3 . The material of the trigger part 3 of the lock block is steel, the diameter of the place where the spring is installed is about 0.01 meter, the diameter of the step is about 0.015 meter, and the length of the short chute 24 is about 0.01 meter. The protrusion at the left end of the connecting rod 7 can slide laterally in the long chute 21 on the limit slide 6, and the right side of the slot hole 22 on the limit slide 6 blocks the slot 25 on the lock block trigger 3. Left side, so that the lock block trigger 3 cannot slide down. The limit sliding piece 6 is a hard steel sheet, the diameter of the grooved hole 22 is 0.01 meter, the length is 0.005 meter, and the length of the long chute 21 is 0.05 meter. Under the normal state, the lock block assembly can slide left and right simultaneously, and the connecting rod 7 does not move, and the projection on the left end of the connecting rod 7 and the long chute 21 on the limit sliding plate 6 have relatively sliding in a small range. When the connecting rod 7 is pulled to move a large distance to the right, it will pull the limit sliding piece 6 to slide to the right relative to the lock block 16 in the transverse chute 19 on the lock block 16, so that the locking groove on the lock block trigger part 3 25 loses the blocking of the grooved hole 22 on the limit sliding piece 6, and the trigger piece 3 of the lock block slides down along the long hole 20 on the fixing piece 5 under the action of the small spring 4, and the trigger piece 3 of the lock block slides the lock The lock block slider projection 23 on the block slider 2 makes the lock block slider 2 slide downwards to achieve the same movement effect as the unlocking of the lock cylinder 15 .

The installation method of the present invention is similar to common mechanical locks, and the lock can be opened automatically only by pressing the mechanical trigger button at the center of the door body during use. In addition, the operation is simple and the cost is relatively low, and it can be used for daily house anti-theft and emergency escape in situations such as earthquakes and fires. It has great application prospect and broad market promotion prospect.
