[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Refer to the instruction manual appendix Figures 1-5 An emergency door lock includes a lock cylinder 1, the lock cylinder 1 includes a housing 11, a lock frame 12 is slidably installed inside the housing 11, a lock tongue 13 is installed at the front end of the lock frame 12, a movable magnet 131 is installed inside the lock tongue 13, a rotatable latch 14 is rotatably installed inside the housing 11, the front end of the latch 14 has a top block 141, the rear side of the lock frame 12 has an inclined surface 121, and a tension spring 15 connects the front end of the latch 14 and the front end of the lock frame 12.

[0023] like Figure 3 As shown, in the open state, the latch 13 retracts into the housing 11. A latch box is installed on the door frame, and a magnet is installed inside the latch box. When the door is closed, the movable magnet 131 attracts the magnet, causing the latch 13 to be drawn into the latch box, thus achieving the purpose of locking the door (locking the door panel 7). At this time, the tension spring 15 is in a stretched state. A square rod 4 is inserted into the middle of the latch 14. When the door is opened, the square rod 4 is rotated, which drives the latch 14 to rotate. The latch 14 pushes the inclined surface 121 through the top block 141, causing the lock frame 12 to move. Thus, the lock frame 12 pulls the latch 13 out of the latch box on the door frame, achieving the purpose of opening the door.

[0024] like Figure 1 As shown, the emergency door lock also includes an inner locking component 2, which is used to install on the side of the door panel 7 located inside the room. The inner locking component 2 includes an inner panel 21 for installation on the door panel 7 and an inner handle 22 rotatably installed on the inner panel 21. One end of the square rod 4 is inserted into the end of the inner handle 22.

[0025] It should be noted that rotating the inner handle 22 from inside the door causes the square rod 4 to rotate, thereby achieving the purpose of opening the door.

[0026] like Figure 1 As shown, the emergency door lock also includes an outer locking component 3, which is used to install on the outdoor side of the door panel 7. The outer locking component 3 includes an outer panel 31 for installation on the door panel 7, and an outer handle 32 rotatably installed on the outer panel 31. One end of the square rod 4 is installed at the end of the outer handle 32.

[0027] It should be noted that when the outer handle 32 is rotated from the outside of the door, the outer handle 32 drives the square rod 4 to rotate, thereby achieving the purpose of opening the door.

[0028] like Figure 2 and Figure 3 As shown, an emergency unlocking assembly 5 is provided on the inner panel 21. The emergency unlocking assembly 5 includes a knob 51 rotatably mounted on the inner panel 21. A lever 52 is fixedly mounted on one end of the knob 51 inside the inner panel 21. A torsion spring 53 is mounted on the knob 51. The torsion spring 53 is used to reset the knob 51 after it is rotated. A lever 120 is fixedly mounted on the rear end of the lock frame 12. The lever 52 is used to move the lever 120.

[0029] It should be noted that when the knob 51 is turned, the knob 51 drives the lever 52 to rotate. The lower end of the lever 52 can push the lever 120 to move. The lever 120 directly drives the lock frame 12 to move, causing the lock frame 12 to bring the bolt 13 out of the rear box on the door frame, thus achieving the purpose of opening the door. Opening the door in this way does not require rotating the square rod 4 and the latch 14. When the lock cylinder 1 malfunctions due to internal rust or other reasons, and the inner handle 22 cannot be turned to open the door, the emergency unlocking component 5 can be used for emergency unlocking.

[0030] Furthermore, such as Figure 2 As shown, a groove 111 is provided on one side of the housing 11, and the lever 120 is slidably disposed in the groove 111.

[0031] It should be noted that when the lock frame 12 moves, the toggle block 120 slides inside the slide groove 111.

[0032] Refer to the instruction manual appendix Figure 4 A locking structure 6 is installed on the inner panel 21. The locking structure 6 includes a locking button 61 rotatably mounted on the inner panel 21 and a locking plate 62 slidably mounted inside the inner panel 21. The inner handle 22 has a groove 221 at one end inside the inner panel 21. The upper end of the locking plate 62 has a protrusion 621. When the protrusion 621 is inserted into the groove 221, the inner handle 22 is locked.

[0033] Furthermore, the locking structure 6 also includes a gear 63 rotatably mounted on the end of the locking button 61, a gear 64 rotatably mounted inside the inner panel 21 that meshes with the gear 63, a pin 65 fixedly mounted on one side of the gear 64, and a through groove 622 opened on the locking plate 62, with the pin 65 sliding inside the through groove 622.

[0034] It should be noted that when the locking button 61 is rotated, the locking button 61 drives the gear 1 63 to rotate, the gear 1 63 drives the gear 2 64 and the pin 65 on it to rotate. The pin 65 slides inside the through groove 622, so the locking plate 62 can be pushed up and down through the pin 65. When the locking plate 62 moves upward, the protrusion 621 is inserted into the groove 221, which can lock the inner handle 22, that is, lock the door. When the locking plate 62 moves downward, the protrusion 621 moves out of the groove 221, and the lock is released.

[0035] The above technical solution can lock the door by setting the locking structure 6. When the inner handle 22 and the outer handle 32 are rotated inside or outside the door, the door cannot be unlocked, thus improving security.

[0036] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
