双向斜舌磁吸静音机械锁体
By designing a beveled structure and magnetic locking sleeve on the bolt, combined with a silent pad and a dual spring system, the bolt automatically adapts and closes the door silently. This solves the problems of inconvenient installation and noise in traditional lock bodies in two-way opening scenarios, improving the user experience and the stability of the lock body.

AI Technical Summary
Traditional door locks require manual adjustment of the bolt installation direction in two-way opening scenarios, which is inconvenient to install, noisy, and affects user experience and lock reliability.
A bidirectional inclined tongue magnetic silent mechanical lock body was designed, which adopts an inclined structure on both sides of the lock tongue and a magnetic sleeve, combined with a silent pad and a double spring system to achieve automatic adaptation of the lock tongue and silent closing. Through the magnetic attraction between the magnetic plate and the magnetic sleeve and the elastic buffer of the spring, the lock tongue is ensured to slide smoothly into the lock slot and noise is reduced.
It can adapt to left-hand and right-hand opening without manually changing the direction of the bolt, reducing installation complexity and noise, improving user experience and the stability and durability of the lock body, and is especially suitable for places with high requirements for quiet operation.

Abstract
Claims
1. Bidirectional oblique tongue magnetic attraction mute mechanical lock body, comprising a lock shell (1) and a matching lock catch groove (2), characterized in that: The lock case (1) is provided with a latch rod (15), and a latch (12) is installed at one end of the latch rod (15). Both sides of the latch (12) are inclined structures. A magnetic engaging sleeve (13) is fitted on the latch (12). A magnetic engaging piece (22) is installed on the inner wall of the lock slot (2). After the latch (12) enters the lock slot (2), it is attracted into the bottom of the lock slot (2) by the magnetic attraction of the magnetic engaging piece (22) and the magnetic engaging sleeve (13). A sound-absorbing pad (14) is provided on the outer wall of the magnetic engaging sleeve (13).
2. The bidirectional latchbolt magnetic silent mechanical lock body according to claim 1, characterized in that: The latch groove (2) is installed on the door frame via the latch groove mounting plate (21), and the lock shell (1) is installed on the door body via the lock shell mounting plate (11).
3. The bidirectional latchbolt magnetic silent mechanical lock body according to claim 1, characterized in that: The latch rod (15) is fitted with a first spring (151) and a second spring (152). A spring stop (153) is provided on the latch rod (15) at the first spring (151) and the second spring (152). The spring stop (153) is fixed on the inner wall of the lock shell (1).
4. The bidirectional latchbolt magnetic silent mechanical lock body according to claim 3, characterized in that: When closing the door, the first spring (151) drives the latch (12) into the lock slot (2). Through the magnetic attraction of the magnetic attraction piece (22) and the magnetic attraction sleeve (13), the latch (12) is attracted into the bottom of the lock slot (2). At this time, the latch rod (15) overcomes the elastic force of the second spring (152) and moves outward from the lock shell (1). The second spring (152) is in a compressed state. When opening the door, the lock cylinder in the lock shell (1) drives the latch rod (15) to retract. The magnetic attraction piece (22) disengages from the magnetic attraction sleeve (13). Under the elastic action of the second spring (152), the latch rod (15) retracts quickly, causing the latch (12) to separate from the lock slot (2).
5. The bidirectional latchbolt magnetic silent mechanical lock body of claim 1, wherein: The lock housing (1) is provided with a sliding baffle (16). When the door is closed, the sliding baffle (16) slides down to lock one end of the latch rod (15). When the door needs to be opened, the sliding baffle (16) slides up to unlock the latch rod (15).
6. The bidirectional latchbolt magnetic silent mechanical lock body according to claim 5, characterized in that: A guide block (3) is provided on the outer side of the sliding baffle (16), and a guide hole is provided on the side wall of the lock shell (1). The guide block (3) slides linearly along the guide hole. A rotary drive (4) is provided at the lower part of the sliding baffle (16). Protrusions are provided on the left and right sides of the rotary drive (4). The rotary drive (4) rotates and engages with the lock shell (1). The rotary drive (4) rotates and drives the protrusions to move the sliding baffle (16) upward, thereby realizing the unlocking operation of the latch rod (15).
7. The bidirectional latchbolt magnetic silent mechanical lock body according to claim 6, characterized in that: A torsion spring (17) is installed on the inner wall of the lock housing (1) at the upper end of the sliding baffle (16). The torsion spring (17) drives the sliding baffle (16) to automatically press down and lock the latch rod (15).
8. The bidirectional latchbolt magnetic silent mechanical lock body of claim 1, wherein: The locking tongue rod (15) is fitted with a guide seat (154), which is fixed inside the lock housing (1), and the locking tongue rod (15) passes through the guide seat (154).
