The second embodiment of the mechanical actuation anti-theft lock has the following action processes:

firstly, controlling the retraction of the oblique tongue by a handle shaft: in a normal state, since the coupling latch 14 is coupled to the latch slide plate 15, the latch 14 is always in an extended state by the return spring i 151 provided in the latch slide plate 15. When the door needs to be opened, the handle is pressed down, the handle shaft 12 rotates, the lock handle driving plate 7 also synchronously rotates, and the push rod 71 pushes the rolling shaft II 152 on the back surface of the latch bolt sliding plate 15, so that the latch bolt 14 is pulled to retract.

Secondly, the lock cylinder controls the main bolt to extend outwards: when a key is inserted into the lock cylinder 11 to rotate, the small gear on the lock cylinder 11 drives the large gear 6 to rotate, and when the large gear rotates 180 degrees, the gear pin 61 on the rear surface of the large gear 6 enters the U-shaped opening groove for alignment, so that two gears of the main lock tongue 13 are extended.

For guaranteeing that the in-process that the main spring bolt stretches out fixes a position main slide, 5 sides of main slide have set up main slide locating plate 17, and the bottom back of main slide locating plate 17 is equipped with spacer pin I171, is equipped with three open slot in 5 bottoms of main slide, and every gear that stretches out of main spring bolt, spacer pin I171 all insert the open slot that corresponds the gear in, realize respectively on the gear that 5 locks of main slide correspond.

Meanwhile, in order to ensure that the two gear pins 61 of the bull gear are in a horizontal state in a non-working state, a gear positioning plate 18 is arranged between the main sliding plate positioning plate 17 and the main sliding plate 5. The horizontal plane of gear locating plate 18 receives gear round pin 61 external force effect of rotation action down, and the downward movement, the main slide locating plate 17 is pressed downwards to spacer pin II 182 of gear locating plate 18 front end simultaneously, and spacer pin I171 breaks away from the open slot of main slide 5 bottom, and main slide 5 is non-locking state, and main slide 5 drives the main spring bolt and moves, and after removing another gear, main slide locating plate 17 is under the traction of reset spring III 181, and spacer pin I171 inserts again in the open slot of another gear.

Thirdly, the lock cylinder controls the retraction of the main bolt: the step and the master lock tongue extension controlled by the lock cylinder are in a reverse process.

Fourthly, the handle shaft 12 controls the main bolt to rapidly extend and retract: the handle shaft 12 rotates and simultaneously drives the lock handle driving plate 7 to rotate, the top of the manual driving plate 16 rotates the manual driving plate 16 under the driving of the push-pull part 73, and a sliding rod 161 on the manual driving plate 16 is connected with the main sliding plate 5, so that the main bolt 13 is quickly extended; on the contrary, the handle shaft rotates in the opposite direction, and the return part of the lock handle driving plate 7 drives the manual driving plate 16 to rotate in the opposite direction, so that the main bolt 13 is quickly retracted. The main sliding plate positioning plate 17 needs to move downwards in the process of rapid extension and retraction of the lock tongue, the limiting pin I171 unlocks the main sliding plate 5, a specific unlocking structure is realized through the positioning groove 71 in the lock handle driving plate 7, the original position of the lock handle driving plate 7 is that the bearing 81 on the main sliding plate opening piece 8 is embedded into the positioning groove 71, when the lock handle driving plate 7 rotates, the bearing 81 is separated from the positioning groove 71 and touches the main sliding plate opening piece 8 to rotate, so that the tail end of the main sliding plate opening piece 8 pushes the stop pin II 172 in the middle of the main sliding plate positioning plate 17, and the main sliding plate positioning plate 17 moves downwards to unlock the main sliding plate 5.

Fifthly, extending a self-priming lock tongue: only when the main bolt 13 is fully extended, the back of the main sliding plate 5 is provided with a stop pin I51 to push the self-priming drive plate 4 to rotate, the upper end of the self-priming drive plate 4 stirs the swing rod 3, and the roller I31 above the swing rod 3 presses down the root of the self-priming bolt 1, so that the front end of the self-priming bolt 1 is lifted up to achieve the self-priming effect of the door leaf and the door frame.

The cam lock tongue extends outwards and is locked: in the process that the main lock 13 is extended, the main sliding plate 5 also moves outwards, and meanwhile the bottom of the main sliding plate 5 is clamped on the end face of the cam head 201, so that the cam head 201 is pushed to extend out of the lock box, at the moment, the moving sliding groove 231 which is obliquely arranged is arranged on the top and bottom hook 23 and driven by the pin to move downwards, the top and bottom hook 23 extends out of the lock box, the opening window 232 on the top and bottom hook 23 pushes the rotating shift lever 22, and the rotating locking of the cam lock tongue 20 is realized.
