The lock tongue spring 507 is clamped between the fixing plate 505 and the soundproof pad 506.

[0025] One end of the push piece 601 is provided with a connecting rod groove 602 which is adapted to be linked with the connecting rod 504, and the other end of the push piece 601 is provided with an axial cavity 603 which is adapted to be linked with the swing shaft 703. The door handle drives the paddle 701 to rotate, and the swing shaft 703 rotates and drives the axial cavity 603 to move left and right, thereby driving the push piece 601 to move left and right. The left and right movement of the push piece 601 drives the connecting rod 504 to move left and right, thereby driving the lock tongue 501 to move left and right. The left and right movement of the push piece 601 is consistent with the movement trajectory of the left and right movement of the lock tongue 501, so that the movement of the lock tongue assembly is very smooth and smooth, the feel of turning the door handle is smooth and comfortable, and the service life is long.

[0026] The mute pad 506 reduces the collision sound between the lock tongue 501 and the connecting rod groove 602 when the lock tongue 501 is extended, thereby playing a mute role.

[0027] The buckle box assembly includes a buckle plate 401 installed on the door frame, a buckle box 402 with a magnet cavity installed on the buckle plate 401, a buckle box magnet 403 embedded in the magnet cavity, and a silent gasket 404 embedded in the magnet cavity for reducing the collision sound of the lock tongue 501 with the buckle box 402 when it is extended.

The bottom plate 101 is provided with a push piece guide hole 103 that guides the left and right movement of the push piece 601, a nut hole 104 for installing the nut 701, and a tension screw hole column 105.

[0030] The slide assembly includes a slide 801 and a torsion spring 802 for restoring the slide 801. The slide 801 is provided with a protrusion 803, a first guide hole 804, and a second guide hole 805. The rotation of the lock core drives the slide 801 to move upward.

[0031] A limiting block 704 extends from the side of the paddle 701 .

[0032] The support column includes a first support column 106 located in the first guide hole 804, a second support column 107 located in the second guide hole 805, a third support column 108 and a fourth support column 109 that limit the limit block 704, one end of the return spring 702 is fixed to the peach 701 and the other end of the return spring 702 is fixed to the third support column 108, a mute sleeve 110 is provided on the third support column 108 to reduce the collision sound between the limit block 704 and the third support column 108, and the torsion spring 802 is fixed to the first support column 106. The first guide hole 804 can move along the first support column 106, and the second guide hole 805 can move along the second support column 107.

[0033] The locking plate 900 is provided with a first limiting groove 901 and a second limiting groove 902, both of which can be engaged with the protrusion 803. The locking plate 900 is provided with an anti-locking hook 903 which can be engaged with or disengaged from the third support column 108. The paddle 701 is provided with an anti-locking limiting block 705. When the anti-locking hook 903 is engaged with the third support column 108, the anti-locking hook 903 limits the anti-locking limiting block 705 to limit the rotation of the paddle 701. The locking plate 900 is provided with a third guide hole 904 and a fourth guide hole 905. The second support column 107 passes through the third guide hole 904, and the third guide hole 904 moves along the third support column 108. The fourth support column 109 passes through the fourth guide hole 905, and the fourth guide hole 905 moves along the fourth support column 109.

[0034] When the door is closed, the lock tongue assembly and the buckle box assembly are close to each other, the buckle box magnet 403 and the lock tongue magnet 503 attract each other and drive the lock tongue 501 to extend into the buckle box 402, thereby changing to a locked door state, and the suction force of the buckle box magnet 403 and the lock tongue magnet 503 causes the lock tongue spring 507 to be in a contracted state so that it has a rebound force.

[0035] When opening the door, the door handle drives the paddle 701 to rotate, the swing shaft 703 rotates and drives the shaft cavity 603 to move rightward, thereby driving the push piece 601 to move rightward, and the rightward movement of the push piece 601 drives the connecting rod 504 to move rightward, thereby driving the lock tongue 501 to disengage from the buckle box 402 and retract to the right. During the door opening process, the distance between the lock tongue assembly and the buckle box assembly gradually increases, and the mutual attraction between the buckle box magnet 403 and the lock tongue magnet 503 decreases. The suction force is less than the rebound force of the lock tongue spring 507. The rebound force of the lock tongue spring 507 resets the lock tongue assembly and converts it into the door opening state.

[0036] When it is necessary to switch to the anti-locking state, the lock core is rotated to push the slide 801 upward, and the protrusion 803 of the slide 801 is separated from the first limiting groove 901 of the lock plate 900. At the same time, the external force drives the lock plate 900 to move to the left, and the slide plate 801 is reset by the rebound force of the torsion spring 802. The protrusion 803 of the slide 801 is engaged with the second limiting groove 902, so that the position of the lock plate 900 is locked and cannot move left or right. The left movement of the lock plate 900 limits the rightward movement of the lock tongue assembly. At the same time, the left movement of the lock plate 900 causes the anti-locking hook 903 to engage with the third support column 108 and the anti-locking hook 903 limits the anti-locking limit block 705, thereby limiting the rotation of the paddle 701.

[0037] When unlocking, the lock core is rotated in the opposite direction so that the lock core pushes the slide 801 upward, and the protrusion 803 of the slide 801 is separated from the second limiting groove 902. At the same time, an external force pushes the lock plate 900 to move to the right, and the slide 801 is reset by the resilience of the torsion spring 802. The protrusion 803 of the slide 801 is engaged with the first limiting groove 901, so that the position of the lock plate 900 is locked and cannot move left or right. The rightward movement of the lock plate 900 provides enough space for the rightward movement of the lock tongue assembly. At the same time, the rightward movement of the lock plate 900 causes the anti-locking hook 903 to disengage from the third support column 108 and the anti-locking hook 903 to disengage from the anti-locking limit block 705, so that the paddle 701 can be rotated.

[0038] In summary, the structure of the magnetic silent lock body is simple and reasonable, the conversion of various states and the transmission between components are smooth and stable, the operation is simple, and the practicability is strong.

[0039] The lining plate assembly includes a lining plate 301 with a lock tongue hole installed on the door panel, a lock tongue cover 302 installed on the inner side of the lining plate 301 and located at the lock tongue hole, and a lining plate support 303 installed between the base plate assembly and the cover plate 201.

[0040] The magnetic silent lock body is provided with multiple silent structures to ensure the silent effect when the lock body parts are working. The silent pad 506 of the lock tongue assembly reduces the collision sound between the lock tongue 501 and the connecting rod groove 602 when it is extended, and plays a silent role. The silent gasket 404 of the buckle box assembly is embedded in the magnet cavity, which can reduce the collision sound between the lock tongue 501 and the buckle box 402 when it is extended, and plays a silent role. The silent block 509 of the lock tongue assembly is embedded in the inner side of the lock tongue inner sleeve 502, which can reduce the collision sound between the lock tongue 501 and the fixed plate 505 when it is retracted, and plays a silent role. The third support column 108 is provided with a silent sleeve 110, which can reduce the collision sound between the limit block 704 and the third support column 108, and play a silent role. The multiple silent structures can ensure that the operations of closing, opening, locking and unlocking are all silent operations, and the silent effect is ideal.

[0041] The present invention realizes a structure that is simple and reasonable, with smooth and stable state conversion and component transmission, the movement of the lock tongue assembly is very smooth, the hand feel is smooth and comfortable when used, and the service life is long. The buckle box assembly is configured as an adjustable structure, so that the installation position of the buckle box 402 can be flexibly adjusted, making the installation work simple and convenient. The assembly of the buckle box magnet 403 is simple and firm, and it is provided with multiple silent structures, and the magnetic silent lock body has an ideal silent effect.

The leftward movement of the locking plate limits the rightward movement of the lock tongue assembly. At the same time, the leftward movement of the locking plate causes the reverse locking hook to engage with the third supporting column, and the reverse locking hook limits the reverse locking limit block, thereby limiting the rotation of the paddle. When unlocking, the lock core is rotated in the opposite direction to push the sliding plate upward, and the protrusion of the sliding plate is separated from the second limiting groove. At the same time, the external force drives the locking plate to move to the right, and the sliding plate is reset due to the rebound force of the torsion spring, and the protrusion of the sliding plate is engaged with the first limiting groove, so that the position of the locking plate is locked and cannot move left or right. The rightward movement of the locking plate provides sufficient space for the rightward movement of the lock tongue assembly. At the same time, the rightward movement of the locking plate causes the anti-locking hook to disengage from the third support column and the anti-locking hook to disengage from the anti-locking limit block, so that the paddle can be rotated.
