The square tongue plate 32 is fixed to the rear of the square tongue 31. The square tongue plate 32 has a pin hole A321, and the square tongue actuating block 34 has a pin hole B341. The rotating pin 33 hinges pin holes A321 and B341 together, allowing them to rotate relative to each other around the rotating pin 33. The square tongue plate 32 has a smooth groove 322 and two actuating grooves 323. The square tongue actuating block 34 has a magnetic tongue actuator 342, a buffer groove 343, and a key actuating block 344. The buffer groove 343 has buffer curved surfaces 3431 at both ends. The smooth groove 322 and the buffer groove 343 are positioned correspondingly and are both threaded onto studs 52 on the bottom assembly 5, sliding along the studs 52.

[0050] The square core pusher assembly 6 includes a square core pusher A62, a square core pusher B63, and two elastic retaining rings 61. The lower end of the square core pusher A62 is provided with a handle head 621, and the upper end is provided with a limiting handle 622. The square core pusher B63 is provided with retaining ring grooves 631 on both sides for securing the elastic retaining rings 61.

[0051] The magnetic tongue assembly 4 includes a magnetic tongue component 42 and a magnetic tongue magnet 41. The magnetic tongue magnet 41 is placed inside the magnetic tongue component 42. A positioning handle 421 is provided at the upper rear end of the magnetic tongue component 42 to keep the magnetic tongue component 42 flush with the end face of the lock body liner 21 when it is retracted. A magnetic tongue box 422 is provided at the upper front end of the magnetic tongue component 42 to fix the magnetic tongue magnet 41. The magnetic tongue magnet 41 can drive the magnetic tongue component 42 to extend and lock the door. A fixed shaft 424 is provided in the middle of the magnetic tongue component 42. The two ends of the fixed shaft 424 are respectively embedded in the magnetic tongue pivot hole A511 of the box bottom 51 and the magnetic tongue pivot hole B71 of the box cover 7. The magnetic tongue component 42 can rotate around the fixed shaft 424. The lower part of the magnetic tongue component 42 is the working end, which is provided with a tumbler working surface 423, a tumbler working groove 425, and a deadbolt block 426. The tumbler working groove 425 is provided with a square tongue locking protrusion 4251 and a magnetic tongue opening protrusion 4252. The tumbler working surface 423 cooperates with the handle tumbler 621 to realize the function of unlocking with the handle. The deadbolt block 426 cooperates with the deadbolt protrusion 324 on the square tongue plate 32 to lock the magnetic tongue component 42. The square tongue locking protrusion 4251 in the tumbler working groove 425 cooperates with the magnetic tongue tumbler 342 to realize the function of locking the square tongue 31. The magnetic tongue opening protrusion 4252 in the tumbler working groove 425 cooperates with the magnetic tongue tumbler 342 and the square tongue assembly 3 to realize the function of unlocking the magnetic tongue component 42 with the key.

[0052] The torsion spring 53 is fixed to the stud 52 of the bottom assembly. Its shorter end rests on the square core toggle assembly 6 to provide initial elastic force for the handle to reset. The other end of the torsion spring 53, near the spiral, is stuck on the bottom 51 of the box and extends a longer section to rest on the upper side of the square tongue toggle block 34 of the square tongue assembly 3 to provide initial elastic force for the magnetic tongue toggle head 342.

[0053] like Figure 4 As shown, when the magnetic tongue 42 is not extended, the fixing shaft 424 of the magnetic tongue 42 is engaged in the magnetic tongue pivot hole A511 of the bottom of the box 51 and the magnetic tongue pivot hole B71 of the cover of the box 7 (see reference). Figure 1 The front of the magnetic tongue component 42 is flush with the lock body liner 21, and the positioning handle 421 is positioned on the magnetic tongue limiting block 512 of the bottom of the box 51. The square core jack assembly 6 is embedded in the jack hole A513 of the bottom of the box 51 and the jack hole B72 of the cover 7 (see reference). Figure 1 Under the elastic force of the torsion spring 53, the limiting handle 622 at the upper end of the square core lever A62 rests against the magnetic tongue limiting block 512 on the bottom of the box 51; the magnetized square core lever assembly 6 and the magnetic tongue magnet 41 attract each other, keeping the magnetic tongue 42 in a retracted state; the elastic retaining ring 61 nested on the square core lever assembly 6 can prevent the square core lever assembly 6 from directly rubbing against the bottom of the box 51 and the box cover 7 when rotating, thus avoiding noise. The square tongue 31 remains in the retracted state, and the anti-locking protrusion 324 on the square tongue plate 32 is away from the anti-locking block 426 at the lower end of the magnetic tongue 42, so the magnetic tongue 42 is in a free state without anti-locking. At this time, the magnetic tongue lever head 342 is locked in the square tongue locking protrusion 4251 in the lever working groove 425, the square tongue assembly 3 is locked, and the square tongue 31 cannot be extended, which can avoid the square tongue 31 accidentally extending and causing adverse effects on the use of the door lock.

[0054] like Figure 5 As shown, after the door is closed, the magnetic tongue magnet 41 in the magnetic tongue assembly 4 attracts the snap box magnet 11 in the snap box assembly 1. The magnetic tongue 42 rotates around the fixed shaft 424 and extends out, snapping into the snap box 13 to lock the door. When snapped in, the magnetic tongue 42 contacts the muffler 12 to prevent collision noise. At this time, the magnetic tongue lever 342 moves away from the square tongue locking protrusion 4251 and can slide within the lever working groove 425, releasing the lock on the square tongue assembly 3, allowing the square tongue 31 to extend.

[0055] like Figure 6 As shown, when the door needs to be locked after closing, the square tongue 31 is pulled out, and the locking protrusion 324 on the square tongue plate 32 approaches the lower end of the magnetic tongue 42 and presses against the locking block 426, so that the magnetic tongue 42 cannot rotate around the fixed shaft 424. The magnetic tongue box 422 will not be able to retract, thus achieving the purpose of locking the magnetic tongue 42.

[0056] like Figure 7As shown, when the square tongue 31 is not extended (or has been retracted), when the handle is used to unlock the door through the square core mortise assembly 6, the handle head 621 contacts the mortise working surface 423 on the magnetic tongue component 42. When the square core mortise assembly 6 is rotated, the handle head 621 slides along the mortise working surface 423, driving the magnetic tongue component 42 to rotate around the fixed shaft 424 as the fulcrum. According to the lever principle, the magnetic tongue box 422 is retracted.

[0057] like Figure 8 As shown, when both the magnetic tongue 42 and the square tongue 31 are extended, a key is required to unlock the door. The key lever (not shown) moves the actuation groove 323 below the square tongue plate 32. The smoothing groove 322 and the buffer groove 343 slide along the stud 52 on the bottom assembly 5, retracting the square tongue assembly 3 inward and retracting the square tongue 31, thus opening the square tongue 31. During this process, the magnetic tongue lever 342 slides within the lever working groove 425 to the magnetic tongue opening protrusion 4252. When the key lever (not shown) is rotated further, the key lever... The key lever 344 below the square tongue lever 34 is moved. The square tongue lever 34 uses the rotating pin 33 as a fulcrum. The buffer curved surface 3431 at the end of the buffer groove 343 at one end of the fulcrum slides upward along the stud 52, while the magnetic tongue lever 342 at the other end of the fulcrum slides downward. This causes the magnetic tongue opening protrusion 4252 to move the magnetic tongue component 42 downward. The magnetic tongue component 42 rotates around the fixed shaft 424, causing the magnetic tongue box 422 to exit from the buckle box 13 and return to the bottom assembly 5, thus realizing the function of the key opening magnetic tongue component 42.

[0058] As can be seen from the above embodiments, the silent magnetic lock body provided by the present invention, through the cooperation of the square latch assembly and the magnetic latch assembly, allows the square latch to be pulled out only after the magnetic latch is extended, and the magnetic latch is locked after the square latch is extended. To open, the square latch is retracted with a key, and then the magnetic latch can be opened with either the key or the handle. The magnetic lock body of the present invention has a simple structure, achieving locking and unlocking functions through the mutual cooperation of the square latch assembly and the magnetic latch assembly.
