[0025] Refer to the attached Figures 1 to 7 The utility model is further described in detail.

[0026] When the door is unlocked, the inner handle 2 and the outer handle 3 are respectively provided with an inner handle 2 and an outer handle 3, the lock body 1 including a lock shell 11 and a lock tongue 12 slidably provided on the lock shell 11; a magnet is provided in the lock tongue 12, and the lock tongue 12 automatically extends out of the lock shell 11 and is placed in the lock box under the magnetic attraction of the magnet of the buckle box in the door frame; an unlocking slider 13 and an unlocking member 14 are slidably provided in the lock shell 11, one end of the unlocking member 14 cooperates with the unlocking slider 13, and the other end cooperates with the lock tongue 12; an unlocking operating member 4 is slidably provided on the inner handle 2 and the outer handle 3, and one end of the unlocking operating member 4 extends into the lock shell 11 and is connected with the unlocking slider 13; when the unlocking operating member 4 is pressed, the unlocking operating member 4 drives the unlocking slider 13 to slide, and the unlocking slider 13 drives the unlocking member 14 to rotate and drives the lock tongue 12 to retract into the lock shell 11;

[0027] The door lock is provided with an unlocking operating member 4 for unlocking on the inner handle 2 and the outer handle 3. By pressing the unlocking operating member 4, the unlocking slider 13 is driven to slide and the unlocking member 14 is driven to rotate. The unlocking member 14 drives the lock tongue 12 to retract into the lock shell 11, thereby realizing the unlocking operation of the door lock. It is used to replace the existing door lock unlocking method of unlocking by rotating the door handle. The inner handle 2 and the outer handle 3 of the door lock are directly fixed to the door panel and are only used to pull the door panel, with a firm structure. It effectively solves the problem that the door handle will shake up and down and droop due to spring fatigue after the existing door lock has been used for a period of time. At the same time, the unlocking operation of the door lock is realized by pressing the unlocking operating member 4, making the unlocking operation of the door lock easier.

[0028] One end of the unlocking slider 13 is provided with a connecting hole 131 for connecting to the unlocking operating member 4, and the other end is provided with a reset spring; one end of the reset spring abuts against the lock housing 11, and the other end abuts against the unlocking slider 13; when the unlocking operating member 4 is pressed to unlock, the unlocking slider 13 will compress the reset spring, and when the unlocking operating member 4 is released, the reset spring drives the unlocking slider 13 to slide in the opposite direction, and drives the unlocking operating member 4 to automatically reset.

[0029] The unlocking operating member 4 includes a sliding plate 41, one end of which is connected to an unlocking button 43, and the unlocking button 43 passes through the unlocking window of the inner handle 2 or the outer handle 3; the other end is connected to a connecting plate 42, and the connecting plate 42 passes through the lock shell 11 and is inserted into the connecting hole 131, thereby realizing the linkage between the unlocking operating member 4 and the unlocking slider 13.

[0030] The inner handle 2 is provided with an anti-locking assembly 21, which includes a sliding anti-locking tooth plate 211 and a rotatable anti-locking member 212. An anti-locking button 2111 is provided on the end of the anti-locking tooth plate 211, and the anti-locking button 2111 passes through the anti-locking window 22 of the inner handle 2.

[0031] The anti-locking member 212 is provided with an inner anti-locking arm 2122 and a tooth portion 2121 engaged with the anti-locking tooth plate 211;

[0032] When the door is locked from the inside, it is only necessary to press the lock button 2111 downward, so that the lock tooth plate 211 drives the lock member 212 to rotate, so that the inner lock arm 2122 abuts against the lower end of the unlocking operating member 4 of the inner handle 2, thereby preventing the unlocking operating member 4 on the inner handle 2 from sliding downward; because the unlocking operating members 4 on the inner handle 2 and the outer handle 3 are jointly connected to the unlocking slider 13, people inside and outside the door cannot unlock the door by pressing the unlocking operating member 4 downward, thereby achieving the door lock.

[0033] When the person inside the door wants to unlock the door lock, he only needs to push the anti-lock button 2111 in the reverse direction to make the anti-lock tooth plate 211 slide upward, so that the anti-lock member 212 drives the inner anti-lock arm 2122 to rotate. The inner anti-lock arm 2122 will separate from the lower end of the unlocking operating member 4 on the inner handle 2, thereby unlocking the door lock.

[0034] The outer handle 3 is provided with an anti-lock lock cylinder 31, one end of which is connected to the anti-lock member 212 via a linkage plate, and the other end is provided with an external anti-lock arm 311; the external anti-lock arm 311 cooperates with the unlocking operating member 4 on the outer handle 3 to realize anti-locking of the door lock;

[0035] The person outside the door rotates the anti-lock lock cylinder 31 in the reverse direction with the key, so that the outer anti-lock arm 311 is separated from the unlocking operating member 4 on the outer handle 3, thereby unlocking the door lock.

[0036] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
