[0035] Refer to the attached Figures 1 to 10 A further detailed description is made of a push-button magnetic-absorption door lock of the present utility model. A push-button magnetic-absorption door lock includes a lock body 1 and an inner handle 2 and an outer handle 3 respectively arranged on both sides of the lock body 1. The lock body 1 includes a lock case 11 and a lock tongue 12 arranged on the lock case 11. A magnet is arranged inside the lock tongue 12, and the lock tongue 12 will automatically extend out of the lock case 11 and be placed inside the fastening box under the magnetic absorption of the magnet in the fastening box inside the door frame;

[0036] An unlocking slider 13 is slidably arranged inside the lock case 11. An unlocking member 131 cooperating with the lock tongue 12 is arranged on the unlocking slider 13. Unlocking buttons 5 are arranged on one side of each of the inner handle 2 and the outer handle 3. A square shaft 133 is inserted through the unlocking slider 13, and both ends of the square shaft 133 penetrate out of the lock case 11 and are respectively connected to the two unlocking buttons 5. When the unlocking button 5 is pressed, the unlocking button 5 drives the unlocking slider 13 to slide through the square shaft 133, so that the unlocking member 131 drives the lock tongue 12 to retract into the lock case 11;

[0037] This door lock is provided with unlocking buttons 5 for unlocking on the inner handle 2 and the outer handle 3. People inside and outside the door press the corresponding unlocking buttons 5. The unlocking buttons 5 will drive the unlocking slider 13 to slide through the square shaft 133, so that the unlocking member 131 on the unlocking slider 13 drives the lock tongue 12 to overcome the magnetic force of the magnet in the fastening box and retract into the lock case 11, realizing the unlocking operation of the door lock; it is used to replace the existing unlocking method of unlocking the door lock by turning the door handle. The inner handle 2 and the outer handle 3 of this door lock are directly fixed on the door panel and are only used to pull the door panel, with a firm structure; effectively solving the problem that after the existing door lock is used for a period of time, the door handle will swing up and down and droop due to spring fatigue; at the same time, the unlocking operation of the door lock can be realized by pressing the unlocking button 5, making the unlocking operation of the door lock more convenient.

[0038] Wherein the unlocking member 131 is rotatably arranged inside the lock case 11. One end of the unlocking member 131 is hinged to the unlocking slider 13, and the other end is matched with the lock tongue 12. The unlocking slider 13 drives the unlocking member 131 to rotate. One end of the unlocking member 131 facing the lock tongue 12 pushes the rear end of the lock tongue 12, so that the lock tongue 12 retracts into the lock case 11, and the unlocking of the door lock can be realized;

[0039] Another setting method of the unlocking member 131 of the door lock: The unlocking member 131 is fixedly arranged on the unlocking slider 13 (or integrally arranged with the unlocking slider 13), and the unlocking member 131 is provided with a matching portion that cooperates with the lock tongue 12; the unlocking slider 13 drives the unlocking member 131 to slide, so that the matching portion on the unlocking member 131 pushes the lock tongue 12 to retract into the lock case 11, and the unlocking of the door lock can be realized.

[0040] In order to realize the anti-lock of the door lock, an anti-lock member 16 is rotatably arranged on the lock body 1, and a linkage plate 161 is connected to the anti-lock member 16; an anti-lock knob 21 is rotatably arranged on the inner handle 2, a lock core 31 is arranged on the outer handle 3, and both ends of the linkage plate 161 pass through the lock case 11 and are respectively connected to the anti-lock knob 21 and the lock core 31; an anti-lock groove 132 adapted to the anti-lock member 16 is arranged on the unlocking slider 13. By driving the anti-lock member 16 to rotate through the anti-lock knob 21 or the lock core 31, when the anti-lock member 16 is placed in the anti-lock groove 132, the anti-lock member 16 is in the anti-lock position, so that the unlocking slider 13 cannot slide on the lock case 11, thereby locking the unlocking slider 13, and thus the unlocking button 5 cannot drive the unlocking slider 13 to unlock, realizing the anti-lock of the door lock;

[0041] When unlocking the door lock, the anti-lock member 16 is driven to rotate in the reverse direction through the anti-lock knob 21 or the key inserted into the lock core 31. One end of the anti-lock member 16 rotates out of the anti-lock groove 132, so that the anti-lock member 16 is in the unlocking position, realizing the unlocking of the door lock; when the anti-lock member 16 continues to rotate, it will push the unlocking slider 13 to slide, driving the unlocking member 131 to push the lock tongue 12 to retract into the lock case 11, realizing the direct unlocking operation of the door lock, without pressing the unlocking button 5 additionally, making the unlocking operation more convenient when the door lock is in the anti-lock state.

[0042] Wherein an elastic member for driving the unlocking slider 13 to reset is arranged in the lock case 11. The elastic member includes a reset tension spring 15 and a first reset spring 14. One end of the reset tension spring 15 is connected to the lock case 11, and the other end is connected to one end of the unlocking slider 13; one end of the first reset spring 14 abuts against the lock case 11, and the other end abuts against the other end of the unlocking slider 13; when the unlocking button 5 drives the unlocking slider 13 to slide, one end of the unlocking slider 13 pulls the reset tension spring 15, and at the same time the other end compresses the first reset spring 14; after the unlocking button 5 is released, one end of the unlocking slider 13 is pulled by the reset tension spring 15, and the other end is automatically reset under the elastic force of the first reset spring 14.

[0043] A positioning torsion spring 17 for positioning the anti-lock member 16 is provided on the lock housing 11. One end of the positioning torsion spring 17 is connected to the lock housing 11, and the other end is connected to the anti-lock member 16. The anti-lock member 16 can be locked in the anti-lock position. When unlocking, it is necessary to overcome the pulling force of the positioning torsion spring 17 to drive the anti-lock member 16 to rotate out of the anti-lock groove 132, preventing the anti-lock member 16 from rotating out of the anti-lock groove 132 by itself and improving the structural stability of the door lock.

[0044] Second return springs 4 for driving the unlocking button 5 to return to its original position are provided on both the inner handle 2 and the outer handle 3. One end of each second return spring 4 abuts against the inner handle 2 or the outer handle 3, and the other end abuts against the unlocking button 5. When the unlocking button 5 is pressed, the unlocking button 5 compresses the second return spring 4. After the unlocking button 5 is released, the unlocking button 5 automatically returns under the elastic force of the second return spring 4.

[0045] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
