Embodiment 1: As shown in Figures 1 to 3, A lock with a mechanical lock mortise includes a main lock mortise 4 and a multipoint hook 3 connected to the main lock mortise 4; the main lock mortise 4 includes a lock mortise seat 1, the lock mortise seat 1 is sequentially provided with a stopper installation slot 11, a lock bolt installation slot 12, a paddle installation slot 13, a first guide bar 14, and a second guide bar 15 from top to bottom, a lock mortise cover plate 2 sealed on the lock mortise seat 1 by screws; the multipoint hook 3 includes a connecting rod 31 and a multipoint hook lock mortise 32 connected up and down with the connecting rod 31; the multipoint hook lock mortise 32 is provided with a multipoint hook lock bolt 321 and a multipoint hook paddle 322.

As a preferred solution, a main paddle 16 is installed on the paddle installation slot 13, the main paddle 16 is buckled with a lock bolt paddle 17, and the main paddle 16 is provided with a square-shaft hole 18 for inserting a square shaft on the connecting part of the main paddle 16 and the lock bolt paddle 17; specifically, the upper end of the main paddle 16 is provided with a first arc-shaped protrusion 161; the bottom end of the lock bolt paddle 17 is provided with a second arc-shaped protrusion 172; the second arc-shaped protrusion 172 is buckled on the first arc-shaped protrusion 161 to form an incomplete ring, so that when the lock bolt paddle 17 rotates counterclockwise, due to the gap between the first arc-shaped protrusion 161 and the second arc-shaped protrusion 172, the lock bolt paddle 17 will not drive the main paddle 16 to move at the same time, only when the second arc-shaped protrusion 172 contacts the first arc-shaped protrusion 161, the main paddle 16 will drive the lock bolt paddle to rotate around the square-shaft hole 18 at the same time.

As a preferred solution, two limit blocks 121 are provided on the lock bolt installation slot 12, the limit block 121 is mounted with a lock bolt of lock mortise 19, a lock bolt spring 20 is also fixedly provided between the lock bolt 19 and the lock mortise seat 1; in a natural state, under the elastic force of the lock bolt spring 20, the lock bolt of lock mortise 19 will pop out on the side of the lock mortise seat 1, the upper surface of the lock bolt of lock mortise 19 is also provided with an arc slot 191; Since the curvature of the slot wall of the arc-shaped slot 191 is different, after inserting the square shaft 171 into the square-shaft hole 18, install the door handle on the square shaft 171 and press the door handle down, the main paddle 16 will rotate clockwise, thereby driving the lock bolt paddle 17 to rotate clockwise. After the front end of the lock bolt paddle 17 gradually slides along the side wall of the arc-shaped slot 191 into the hook slot 192 at the end of the arc-shaped slot 191, the lock bolt paddle 17 is engaged with the hook slot 192, and the lock bolt paddle 17 drives the lock bolt of lock mortise 19 moves in the direction of the lock bolt spring 20. As a further specific implementation scheme of the above-mentioned door opening action, a multipoint hook slider 23 is movably installed on the first guide bar 14, a square protrusion 231 is provided on the multipoint hook slider 23, and a mounting hole 232 is also provided on the side of the multipoint hook slider 23. the mounting hole 232 is fixedly connected with the connecting rod protrusion 311 on the connecting rod 31; The square shaft drives the main paddle 16 to rotate clockwise, thereby driving the lock bolt paddle 17 to drive the lock bolt of lock mortise 19 to move in the direction of the lock bolt spring 20, the installation position of the main paddle 16 is at the lower end of the square protrusion 231, so the main paddle 16 will push the square protrusion 231 upward along the direction of the lock bolt 19, driving the multipoint hook slider 23 to move on the first guide block 14 toward the lock bolt 19, thereby the connecting rod 31 connected to the multipoint hook slider 23 will rise, and the multipoint hook lock bolt 321 connected to the connecting rod 31 will also retract; thus the door opening action is realized; it should be noted that after unlocking, when the door handle is released, the lock bolt of lock mortise 19 is ejected to the side of the lock mortise seat 1 by a small part through the resilience of the lock bolt spring 20 and the locking position of the lock bolt stopper 21.

The lock bolt paddle 17 will rotate counterclockwise and come out of the hook slot 192 at the end of the arc slot 191. Since there is a gap between the first arc-shaped protrusion 161 and the second arc-shaped protrusion 172, when the lock bolt paddle 17 rotates within the above gap stroke, the lock bolt paddle 17 will not drive the main paddle 16 to move synchronously. In order to prevent the lock bolt paddle 17 from touching the multipoint hook slider 23 when the lock bolt spring 20 is ejected, the main paddle 16 will idly rotate to a certain angle when rotating counterclockwise. When idling, the multipoint hook slider 23 will not be moved downward by the main paddle 16.

It should be noted that, in order to prevent the multipoint hook slider 23 from falling down due to gravity, a spring mounting hole 233 is also provided on the top surface of the multipoint hook slider 23. A multipoint hook slider spring 234 is also installed in the spring mounting hole 233, and a multipoint hook slider steel ball 235 is fixed on the multipoint hook slider spring 234.When the multipoint hook slider 23 is in the upper limit position, the multipoint hook slider steel ball 235. 235 will be clamped in the first hole 26 on the lock mortise cover 2. When the multipoint hook slider 23 is at the lower limit, the multipoint hook slider steel ball 235 is clamped in the second hole 27 on the lock mortise cover 2. As a preferred solution, a trapezoidal limit block 111 is provided at one end of the bolt stopper installation slot 11 close to the lock bolt of lock mortise 19. A lock bolt stopper 21 is also provided on the trapezoidal limit block 111 at one end far away from the lock bolt of lock mortise 19, the lock bolt stopper 21 is arranged in an inverted V shape, and is overlapped on the trapezoidal limit block 111. Among them, the lock bolt stopper 21 can be divided into an abutment part 211 and a elastic top 212, and a bolt stopper spring 22 is provided between the rear end of the elastic top 212 and the inner side wall of the lock mortise seat 1. In a natural state, the elastic top 212 of the lock bolt stopper 21 protrudes from the side of the lock mortise seat 1, the abutment part 211 abuts against the inverted angle 193 of the side of the lock bolt of lock mortise 19, so as to prevent the lock bolt of lock mortise 19 from being completely ejected outward under the action of the lock bolt spring 20. When closing the door, the squeezing force of the door panel will push the elastic top 212 of the lock bolt stopper 21 to move in the direction of the bolt stopper spring 22, and the lock bolt stopper 21 will move in the diagonally upward direction. When the abutting part 211 and the inverted angle 193 of the side of the lock bolt of lock mortise 19 are not in the same horizontal plane (that is, the abutting part 211 no longer blocks the inverted angle 193 of the side of the lock bolt of lock mortise 19); The inverted angle 193 is unhooked, and then the lock bolt of lock mortise 19 is pushed out by the lock bolt spring 20. thereby completing the automatic lock of the lock bolt of lock mortise 19. When the lock bolt of lock mortise 19 is ejected, it will not generate any external force to the multipoint hook slider 23; therefore, the multipoint hook lock bolt 321 can maintain the retracted state. When the door handle is lifted, the main paddle 16 will continue to be pressed down, thereby to push the multipoint hook slider 23 to slide down, and the multipoint hook slider 23 drives the connecting rod 31 to slide down. Thereby, the multipoint hook lock bolt 321 is driven to pop out, and the doorislocked. It should be noted that when the door is opened, the lock bolt of lock mortise 19 retracts into the lock bolt spring 20. The inverted angle 193 of the lock bolt of lock mortise 19 will be caught by the abutment part 211 (the elastic top 212 of the lock bolt stopper 21 will protrude from the side of the lock mortise seat 1). Meanwhile, the lock bolt of lock mortise 321 of the multipoint hook will remain in the original position; the automatic lock will not be affected. As a preferred solution, a lock cylinder slider 24 is slidably provided on the second guide bar 15, a side of the lock cylinder slider 24 is provided with an oblique slot 241, and one side of the oblique slot 241 is provided with a lock cylinder 25. A convex block 251 is provided on the side of the lock cylinder 25, after the key is inserted into the convex block 251 and the oblique slot 241, the key can be turned clockwise or counterclockwise, the convex block 251 will rotate around itself. The convex block 251 rotates clockwise while generating thrust on the side surface of the oblique slot 241, so that the lock cylinder slider 24 slides in the direction of the lock bolt of lock mortise 19. In this embodiment, the specific setting position of the main paddle 16 is in the area between the square protrusion 231 and the lock cylinder slider 24. Therefore, when the lock cylinder slider 24 moves in the direction of the lock bolt of lock mortise 19,it contacts with the main paddle 16 and drives the main paddle 16 to move in the direction of the lock bolt of lock mortise 19, and it also can drive the multipoint hook slider 23 move toward to the lock bolt 19.

While the main paddle 16 moves clockwise, the lock bolt paddle 17 also moves clockwise, thereby driving the lock bolt of lock mortise 19 to slide in the direction of the lock bolt spring 20 to realize the unlocking of the lock mortise and the locking of the unlocked lock bolt 19.

The above are only preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modification, equivalent replacement, improvement, etc., made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
