[0024] Preferred embodiments of the present disclosure

[0025] In order to better understand the purpose, structure and function of the present disclosure, the following is a further detailed description of the anti-falling device of a magnetic lock disclosed in the present disclosure in conjunction with the accompanying drawings.

[0026] As shown in Figures 1, 2 and 3, a magnetic lock anti-falling device is shown in an embodiment of the present disclosure. The magnetic lock includes a lock 12 fixed on a door frame 11 and a relay iron plate 21 fixed on a door body 22. The anti-falling device includes a lock anti-falling unit 01 and a relay iron plate anti-falling unit 02. The lock anti-falling unit 01 is used to prevent the lock 12 from falling, and the relay iron plate anti-falling unit 02 is used to prevent the relay iron plate 21 from falling.

[0027] Specifically, the magnetic lock includes a lock 12 and a relay plate 21. Generally, the lock 12 is fixed to the door frame 11, and the relay plate 21 is fixed to the door body 22. The falling of the magnetic lock includes the falling of the lock and the relay plate. Therefore, the anti-falling device of the magnetic lock of this embodiment includes a lock anti-falling unit 01 and a relay plate anti-falling unit 02. The lock anti-falling unit 01 is used to prevent the lock 12 from falling, and the relay plate anti-falling unit 02 is used to prevent the relay plate 21 from falling, thereby reducing safety accidents caused by the falling of the magnetic lock.

[0028] In a specific embodiment, as shown in FIG1 and FIG3 , the lock anti-fall unit 01 includes a first flexible connector 15 , one end of the first flexible connector 15 is fixed to the door frame 11 , and the other end of the first flexible connector 15 is connected to the lock 12 .

[0029] Specifically, the lock anti-fall unit 01 of this embodiment includes a first flexible connector 15, one end of which is fixed to the door frame 11, and the other end of which is connected to the lock. Therefore, when the lock fixing screw 17 between the lock and the door frame 11 loosens and the lock begins to fall, the first flexible connector 15 pulls the lock, thereby preventing it from falling.

[0030] In a specific embodiment, a threading hole is provided on the lock, and the other end of the first flexible connector 15 passes through the threading hole and is connected to a damping plate 16 . The damping plate 16 is used to prevent the lock from being separated from the first flexible connector 15 .

[0031] Specifically, for example, the lock is provided with a threading hole for the first flexible connector 15 to pass through. The other end of the first flexible connector 15 passes through the threading hole and is connected to the damping plate 16. The damping plate 16 cannot pass through the threading hole on the lock. Therefore, the damping plate 16 prevents the lock from being separated from the first flexible connector 15. Moreover, the damping plate 16 is located inside the lock and is concealed, which does not affect the appearance of the lock.

[0032] Therefore, when the lock fixing screw 17 between the lock and the door frame 11 loosens and the lock begins to fall, due to the presence of the damping plate 16, the lock can only be hung on the first flexible connector 15, thereby preventing the lock from falling.

[0033] As an alternative, the other end of the first flexible connector 15 and the lock may be fixedly connected, for example, by tying the other end of the first flexible connector 15 to the lock.

[0034] In a specific embodiment, one end of the first flexible connector 15 is connected to the first connector 14 , and the first connector 14 is fixed to the door frame 11 .

[0035] In this embodiment, one end of the first flexible connector 15 is fixed to the door frame 11 via a first connector 14. The first connector 14 may be a pin or a screw.

[0036] In a specific embodiment, for example, the first flexible connector 15 is a first flexible rope, and the first connector 14 is a first expansion bolt.

[0037] Again, during installation, the lock 12 is fixed to the lock mounting bracket 13 via the lock fixing screws 17, and the lock mounting bracket 13 is fixed to the door frame 11, thereby achieving the purpose of fixing the lock to the door frame 11. In combination with the first flexible connector 15 and the first connector 14, after the lock mounting bracket 13 is fixed to the door frame 11, the first connector 14 is first passed through the lock mounting bracket 13 and fixed to the door frame 11, one end of the first flexible connector 15 is tied to the first connector 14, and the other end of the first flexible connector 15 is passed through the threading hole on the lock and connected to the damping plate 16. Finally, the lock is fixed to the lock mounting bracket 13.

[0038] In the disclosed embodiment, the first flexible connector 15 is located between the lock and the door frame 11 , the first connector 14 is located inside the door frame 11 , and the damping plate 16 is located inside the lock. Therefore, they are all concealed installations and will not affect the appearance of the lock.

[0039] In a specific embodiment, as shown in Figures 2 and 3, the iron plate anti-fall unit 02 includes a second flexible connector 25, one end of the second flexible connector 25 is fixed to the door body 22, and the other end of the second flexible connector 25 is connected to the iron plate 21.

[0040] Specifically, the iron plate anti-fall unit 02 of this embodiment includes a second flexible connector 25, one end of which is fixed to the door body 22, and the other end of the first flexible connector 15 is connected to the iron plate. Therefore, when the iron plate begins to fall, the second flexible connector 25 pulls the iron plate to prevent it from falling.

[0041] In a specific embodiment, one end of the second flexible connector 25 is connected to the second connector 24 , and the second connector 24 is fixed to the door body 22 .

[0042] In this embodiment, the second flexible connector 25 is fixed to the door body 22 via the second connector 24 . The second connector 24 may be a pin or a screw.

[0043] In a specific embodiment, for example, the second connecting member 24 is a second expansion bolt, and the second flexible connecting member 25 is a second flexible rope.

[0044] In a specific embodiment, the iron plate 21 is connected to the iron plate mounting bracket 23 through the iron plate mounting bolts 26, the iron plate mounting bracket 23 is fixed to the door body 22, and the other end of the second flexible connector 25 passes through the iron plate mounting bracket 23 and is connected to the iron plate.

[0045] In this embodiment, the other end of the second flexible connector 25 passes through the iron plate mounting bracket 23 and is connected to the iron plate. Therefore, the second flexible connector 25 in this embodiment can also be used to prevent the iron plate mounting bracket 23 from falling. Specifically, one end of the second flexible connector 25 is fixed to the door body 22, and the other end of the second flexible connector 25 is connected to the iron plate. The second flexible connector 25 passes through the iron plate mounting bracket 23, and the iron plate cannot pass through the iron plate mounting bracket 23. Therefore, even if the iron plate mounting bracket 23 falls, the iron plate mounting bracket 23 can only be hung on the second flexible connector 25.

[0046] In a specific embodiment, the iron plate mounting bracket 23 is provided with a through hole for the second flexible rope to pass through.

[0047] The anti-falling device of the magnetic lock of the embodiment of the present disclosure has the advantage of easy installation, and there is no need to change the lock and the relay plate of the original magnetic lock; the anti-falling device of the magnetic lock of the embodiment of the present disclosure reduces the problem of injuring pedestrians below due to the falling of the lock or the falling of the relay plate.
