[0030] See attached document Figures 1 to 8 This utility model provides a more detailed description of a pull-type magnetic door lock.

[0031] A pull-type magnetic door lock includes a lock body 1 and an inner panel 2 and an outer panel 3 respectively disposed on both sides of the lock body 1. The lock body 1 includes a lock shell 11 and a bolt 12 slidably disposed on the lock shell 11. An unlocking slider 13 that cooperates with the bolt 12 is slidably disposed inside the lock shell 11. An inner pull plate 21 and an outer pull plate 31 are rotatably disposed on the inner handle and the outer handle respectively. An inner push rod 211 is connected to the lower end face of the inner pull plate 21, and an outer push rod 311 is connected to the lower end face of the outer pull plate 31. The outer pull plate 31 and the inner pull plate 21 have the same structure, and the outer push rod 311 and the inner push rod 211 have the same structure. One end of the inner push rod 211 passes through one side of the lock shell 11 and cooperates with the unlocking slider 13, and one end of the outer push rod 311 passes through the other side of the lock shell 11 and cooperates with the unlocking slider 13.

[0032] The inner pull plate 21 drives the inner push rod 211 to swing downward, and the inner push rod 211 pushes the unlocking slider 13 to retract the lock tongue 12 into the lock shell 11. The outer pull plate 31 drives the outer push rod 311 to swing downward, and the outer push rod 311 pushes the unlocking slider 13 to retract the lock tongue 12 into the lock shell 11.

[0033] When performing the unlocking operation, simply pull the inner pull plate 21 or the outer pull plate 31 outward. The inner push rod 211 or the outer push rod 311 drives the unlocking slider 13 to slide, causing the unlocking slider 13 to drive the bolt 12 back into the lock case 11, thus realizing the unlocking operation of the door lock. This method replaces the traditional door lock unlocking method of turning the door handle, effectively solving the problem that after a period of use, the door handle will wobble and sag due to spring fatigue. At the same time, the door lock unlocking operation is made simpler by pulling the inner pull plate 21 or the outer pull plate 31. In addition, the inner push rod 211 and the outer push rod 311 are not linked and operate independently, making it easier to pull the inner pull plate 21 and the outer pull plate 31.

[0034] The inner push rod 211 is provided with a first return spring 212 on its lower side to drive the inner push rod 211 to reset. The two ends of the first return spring 212 are fixed to the inner panel 2 and respectively placed on both sides of the inner push rod 211. When the inner push rod 211 swings downward, it will pull the first return spring 212 downward. After unlocking, the inner pull plate 21 is released, and the inner push rod 211 drives the inner pull plate 21 to swing in the opposite direction under the drive of the first return spring 212 to achieve automatic reset.

[0035] The lower side of the outer push rod 311 is provided with a second return spring 312 that drives the outer push rod 311 to reset. The two ends of the second return spring 312 are fixed to the outer panel 3 and are respectively placed on both sides of the outer push rod 311. When the outer push rod 311 swings downward, it will pull the second return spring 312 downward. After unlocking, the outer pull plate 31 is released, and the outer push rod 311 drives the outer pull plate 31 to swing in the opposite direction under the drive of the second return spring 312, so as to achieve automatic reset.

[0036] The unlocking slider 13 is provided with a third return spring 15. The upper end of the third return spring 15 is fixed to the lock housing 11, and the lower end is fixed to the unlocking slider 13. The inner push rod 211 or the outer push rod 311 pushes the unlocking slider 13 to slide, and the unlocking slider 13 pulls the third return spring 15 downward. After unlocking is completed, the unlocking slider 13 slides upward under the drive of the third return spring 15 to achieve reset.

[0037] In order to better drive the unlocking slider 13 to reset, there are two third reset springs 15, with the two third reset springs 15 respectively located on both sides of the unlocking slider 13; so that the unlocking slider 13 is more stable during sliding and avoids tilting.

[0038] The upper end of the unlocking slider 13 is provided with a mating hole 131 that passes through both sides. The ends of the inner push rod 211 and the outer push rod 311 are placed side by side in the mating hole 131. When the inner pull plate 21 or the outer pull plate 31 is pulled, the inner push rod 211 or the outer push rod 311 pushes the unlocking slider 13 to slide, thereby realizing the unlocking operation.

[0039] The lock housing 11 is rotatably provided with an unlocking component 14. One end of the unlocking component 14 is hinged to the unlocking slider 13, and the other end cooperates with the bolt 12. The unlocking slider 13 drives the unlocking component 14 to rotate, and the unlocking component 14 pushes the rear end of the bolt 12 towards the bolt 12, causing the bolt 12 to retract into the lock housing 11, thereby unlocking the door lock.

[0040] The upper surfaces of the inner panel 2 and the outer panel 3 are both recessed downwards and provided with a handle 4, which makes it easy for the user to hold the handle 4 and pull the inner pull plate 21 and the outer pull plate 31 outwards.
