[0043] Embodiment 1 of the present utility model is referred to Figures 1-7 As shown, a folding door magnetic lock mechanism is disclosed, including a lock slot device 1 and a magnetic lock device 2, wherein one of the lock slot device 1 and the magnetic lock device 2 is mounted on the folding door body, and the other is mounted on a track or a door frame, wherein the lock slot device 1 has a concave accommodating space 11, wherein a first magnetic attraction portion 111 is arranged in the accommodating space 11, wherein the magnetic lock device 2 comprises: a lock housing 21, a lock tongue 22 that can extend from the lock housing 21, a first reset member 23, an unlocking trigger member 3, and a second reset member 24, wherein the lock tongue 22 is movably limited in the lock housing 21, wherein a second magnetic attraction portion 221 that attracts the first magnetic attraction portion 111 is arranged on the lock tongue 22, and when the magnetic lock device 2 and the lock slot device 1 are engaged, the lock tongue 22 is locked. When relative to each other, the first magnetic attraction portion 111 and the second magnetic attraction portion 221 trigger the attraction for sliding the lock tongue 22 into the accommodating space 11. Preferably, the first magnetic attraction portion 111 and the second magnetic attraction portion 221 are both provided with magnets, and the first reset member 23 provides a reset force for the lock tongue 22 to slide into the lock shell 21, and the unlocking trigger member 3 is used to provide an unlocking force for the lock tongue 22 to separate from the accommodating space 11, and the second reset member 24 is used to provide a reset force for the unlocking trigger member 3; wherein, when unlocking, the unlocking force triggering the unlocking trigger member 3> the attraction between the first magnetic attraction portion 111 and the second magnetic attraction portion 221> the reset force of the second reset member 24> the reset force of the first reset member 23.

[0044] Preferably, the first return member 23 is a spring, and / or the second return member 24 is a spring. The spring has excellent elastic restoring force and can quickly return to its original shape and size after being acted upon by an external force. At the same time, the manufacturing cost of the spring is relatively low and it is easy to obtain.

[0045] It should be noted that, see Figures 2-4 As shown, the magnetic lock device 2 is provided with a lock body assembly part 25, and the lock slot device 1 is provided with a lock slot assembly part 12. One of the magnetic lock device 2 and the lock slot device 1 is assembled on the folding door through the locking member 4, and the other is assembled on the folding door frame or track through the locking member 4. Preferably, the lock body assembly part 25 is an inclined locking screw hole, which is arranged on one side of the lock shell 21 and inclined toward the door frame or folding door. The two can be directly fixed by screwing in the locking member 4. The locking member 4 is preferably a screw with threads, and the lock slot assembly part 12 is a screw hole, which is directly passed through the screw hole by the locking member 4 to be fixed to the door frame or folding door. Since the magnetic lock device 2 and the lock slot device 1 are respectively fixed on the door and the door frame or track, the cooperation between them is more compact and stable. This helps to ensure the effective transmission of magnetic force and the accurate insertion of the lock tongue 22 during locking, thereby improving the locking effect and safety performance.

[0046] By assembling the lock slot device 1 and the magnetic lock device 2 on the folding door body and the track or door frame respectively, the exposure problem of the traditional hook-shaped lock structure is avoided. Whether it is a child or an adult, it is not easy to directly contact the sharp or protruding lock structure in daily activities, thereby greatly reducing the risk of accidental collision. In this embodiment 1, the lock slot device 1 is assembled at the bottom of the folding door, and the magnetic lock device 2 is arranged in the track below the folding door. When in use, when the magnetic lock device 2 of the folding door slides to overlap with the lock slot device 1, the magnetic attraction between the two attracts the lock tongue 22 of the magnetic lock device 2 to the accommodation space 11 of the lock slot device 1. At this time, the folding door is locked and cannot slide. When unlocking is required, the unlocking trigger 3 is manually triggered to pull the lock tongue 22 back out of the accommodation space 11. At this time, the folding door can be unlocked and can slide. The unlocking trigger 3 can be linked with the door handle to realize the trigger unlocking. For example, the door handle can be turned to pull the unlocking trigger 3 through the pull rope, thereby driving the lock tongue 22 to descend and escape from the accommodation space 11 to realize the unlocking operation. Since the magnetic lock device 2 can be automatically locked after closing the door, the user experience is greatly improved, and when unlocking, the user can directly realize the unlocking operation by triggering the unlocking trigger member 3, which is convenient to operate.

[0047] Specifically, in one embodiment, see Figure 6As shown, the lock housing 21 includes an outer housing 211 and a cover 212. The inner part of the outer housing 211 includes a bolt cavity 213 and an unlocking cavity 214. The bolt cavity 213 and the unlocking cavity 214 are adjacent and separated by a partition. The outer housing 211 where the unlocking cavity 214 is located is provided with two opposite rotating shaft grooves 215. The unlocking trigger 3 rotates within the rotating shaft grooves 215. The bolt 22 includes a sliding block 222 and a locking block 223. The sliding block 222 slides within the bolt cavity 213, and at least part of the sliding block 222 abuts against the cover 212. A clamping groove 224 is provided on the sliding block 222 for clamping with the unlocking trigger 3. The locking block 223 is fixedly connected to the sliding block 222 and can extend out of the bolt cavity 213 from the lock hole 2121. The stable sliding of the sliding block 222 within the bolt cavity 213 ensures the smoothness of the bolt 22 during the locking and unlocking processes. At the same time, the clamping groove 224 located within the bolt cavity 213 is not interfered, making the clamping and unlocking action between the clamping groove 224 and the unlocking trigger 3 more reliable. The cover 212 and the outer housing 211 are detachably connected, facilitating the repair of the interior of the outer housing 211. Preferably, the cover 212 and the outer housing 211 are fixedly connected by screws to cover the bolt cavity 213 and the unlocking cavity 214. The cover 212 is provided with a lock hole 2121 corresponding to the bolt cavity 213, facilitating part of the bolt 22 to extend out of the bolt cavity 213 from the lock hole 2121. The cover 212 can limit the whole bolt 22 to prevent the bolt 22 from detaching from the outer housing 211. In this Embodiment 1, the sliding block 222 and the locking block 223 are clamped and fixed. In other embodiments, the sliding block 222 and the locking block 223 can be integrally formed. Of course, other fixing methods can also be adopted, and this Embodiment 1 does not make specific limitations.

[0048] In one embodiment, referring to Figure 7As shown, the unlocking trigger 3 includes a rotating shaft rod 31, a trigger block 32, and an unlocking rotating block 33. Preferably, the rotating shaft rod 31, the trigger block 32, and the unlocking rotating block 33 are integrally formed. In other embodiments, they can also be adhesively connected, welded, or snap-connected. The rotating shaft rod 31 is provided with a first rotating portion 311 and a second rotating portion 312 that are respectively rotatably connected to two rotating shaft grooves 215. The trigger block 32 is connected to the rotating shaft rod 31 between the first rotating portion 311 and the second rotating portion 312. The trigger block 32 is sequentially provided with a second driving portion 322 and a first driving portion 321 along the axis of the rotating shaft rod 31 outward. At least a part of the first driving portion 321 extends into the lock tongue cavity 213 and is snap-connected to the lock tongue 22. In this Embodiment 1, the first driving portion 321 abuts and is snap-connected to the positioning groove 224 of the lock tongue 22. One end of the second reset member 24 abuts against the second driving portion 322, and the other end abuts against the cavity wall of the unlocking cavity 214. Optionally, in order to prevent the second reset member 24 from being pushed away from the compression track when being squeezed by the second driving portion 322, a first reset member mounting portion 323 can be provided below the second driving portion 322, and a second reset member mounting portion 2141 can be provided on the cavity wall of the unlocking cavity 214. Preferably, the second reset member 24 is a spring, and the first reset member mounting portion 323 and the second reset member mounting portion 2141 are snap bumps. The snap bumps can be inserted into one end of the spring to ensure that the lock tongue 22 can fall and reset under the action of the first reset member 23 and its own gravity when not magnetically attracted, avoiding jamming. The unlocking rotating block 33 is assembled at one end of the trigger block 32 and is exposed outside the outer housing 211. Optionally, the unlocking rotating block 33 extends outward along the axis of the rotating shaft rod 31, and the extended portion is provided with an installation hole 331. The installation hole 331 can be assembled with a pull rope, and the other end of the pull rope is connected to the handle. Thus, the handle can drive the pull rope to trigger the rotation of the rotating shaft rod 31, and then the lock tongue 22 can be pressed into the lock tongue cavity 213 through the first driving portion 321, and finally the lock tongue 22 can be unlocked. The rotational connection between the rotating shaft rod 31 and the rotating shaft groove 215 provides a stable rotation fulcrum for the unlocking trigger 3, enabling the trigger block 32 to rotate smoothly when subjected to an external force, thereby driving the unlocking action of the lock tongue 22, and the second reset member 24 can automatically reset the unlocking trigger 3 to the initial state to prepare for the next locking.

[0049] Due to different installation sites of the folding door, there will be different distances between the door frame and the folding door. In order to adapt to the magnetic attraction locking effect of the lock tongue 22 of the magnetic attraction lock device 2 that can be triggered under folding doors and door frames with different distances, a lock tongue adjusting device 5 is provided on the magnetic attraction lock device 2. The lock tongue adjusting device 5 is used to adjust the position of the lock tongue 22 after being reset by the first reset member 23, and can adjust the lowest distance that the lock tongue 22 extends according to the distance between the folding door and the door frame, so as to achieve the magnetic attraction locking effect in the closed state.

[0050] In a specific embodiment, referring to Figure 6 as shown, the bolt adjusting device 5 includes a driving plate 51 and an adjusting member 52. The driving plate 51 has a driving inclined surface 511. An abutting surface 225 with the same slope as the driving inclined surface 511 is provided on the bolt 22. The driving plate 51 is partially bent, and the adjusting member 52 is inserted through the bent part of the driving plate 51 to drive the driving plate 51 to move. Preferably, the adjusting member 52 is an adjusting screw, and the adjusting screw is connected to the lock housing 21. At the same time, a snap ring is provided on the adjusting screw to keep the adjusting member 52 and the adjusting screw relatively stationary. By rotating the adjusting screw, the driving plate 51 can be driven to move in a direction perpendicular to the sliding direction of the bolt 22. In this Embodiment 1, the adjusting screw drives the driving plate 51 to slide horizontally, so as to drive the longitudinal adjustment of the bolt 22, so that the bolt 22 can achieve the effect of magnetic attraction in the accommodation space 11.

[0051] In order to make the magnetic lock device 2 and the lock groove device 1 face each other when the folding door needs to be locked during the sliding process, referring to Figures 4-6 as shown, a baffle 26 is provided on the magnetic lock device 2 for abutting and positioning with one end of the lock groove device 1. When one end of the lock groove device 1 abuts against the baffle 26, the first magnetic attraction part 111 and the second magnetic attraction part 221 trigger the attraction force. That is, by setting the baffle 26, it can be avoided that the folding door slides excessively when closing and exceeds the magnetic attraction range, improving the locking rate of the magnetic lock and achieving an effective limiting effect. In this Embodiment 1, the baffle 26 is arranged on a separate assembly part, and this assembly part is fixed to the lock housing 21 by screws.

[0052] In summary, a folding door magnetic lock mechanism provided by the present utility model has the following technical effects:

[0053] 1. By arranging the magnetic lock device 2 at the top or bottom of the folding door, the potential safety hazard of the traditional hook-shaped lock structure being exposed outside is avoided, reducing the chance of children or other family members coming into contact with the sharp lock structure during daily activities, thereby reducing the risk of accidental collision and injury. Similarly, due to the relatively concealed installation position of the magnetic lock device 2, the failures and replacement requirements caused by wear are reduced, greatly reducing the risk of damage to the lock structure due to external forces and extending the service life of the lock mechanism;

[0054] 2. The magnetic attraction lock device 2 can be locked by magnetic attraction.
