[0002] A door lock is a commonly used door protection device to prevent illegal intrusion. It usually includes a lock body, an inner door handle and an outer door handle installed inside and outside the door, and an anti-locking mechanism. The anti-locking mechanism is an internal mechanism of the door lock set to improve indoor privacy.

[0003] For example, the Chinese utility model patent with the announcement number CN216043101U discloses a worm-type anti-locking mechanism of a door lock, including an inner door handle and an outer door handle, wherein the inner door handle is rotatably set on the inner panel, and the outer door handle is rotatably set on the outer panel, wherein the inner door handle and the outer door handle are connected by a square shaft; the inner door handle is equipped with an anti-locking assembly, and the outer door handle is equipped with a locking assembly, and the anti-locking assembly is linked to the locking assembly through a rotating rod; the anti-locking assembly includes an anti-locking worm connected to the rotating rod and an anti-locking worm that drives the anti-locking worm to rotate. The lock drive member, the anti-lock drive member is slidably set on the inner door handle, and one end thereof cooperates with the helical teeth of the anti-lock worm; only the anti-lock drive member needs to be pressed, and one end of the anti-lock drive member squeezes the helical teeth and drives the anti-lock worm to drive the rotating rod to rotate, and the locking assembly is driven by the rotating rod to lock the outer door handle; the anti-lock assembly of the door lock drives the anti-lock worm to rotate by pressing the helical teeth downward by the upper drive rod or pushing the helical teeth upward by the lower drive rod, so as to drive the rotating rod to rotate, but this method is prone to the problem of the anti-lock assembly running not being smooth, resulting in the door lock running being stuck.

DETAILED DESCRIPTION

[0023] Refer to the attached Figures 1 to 7 The anti-locking mechanism of the ecological door lock of the utility model is further described in detail.

[0024] A locking mechanism for an ecological door lock includes an inside handle 1, on which a locking assembly 2 is mounted. The locking assembly 2 includes a rotatable locking member 21, a slidable locking slide 22, and a linkage member 23. The lower end of the locking member 21 is connected to a linkage plate 3, wherein the other end of the linkage plate 3 is linked to a locking assembly on the outside handle. A linkage column 211 is eccentrically provided at the upper end. One end of the linkage member 23 is provided with a linkage long slot 232 adapted to the linkage column 211, and the other end is rotatably mounted on the locking slide 22.

[0025] When the door is locked, the anti-locking slide 22 only needs to be pushed to one side. The anti-locking slide 22 drives the anti-locking rotating member 21 to rotate through the linkage member 23. The anti-locking rotating member 21 drives the linkage plate 3 to rotate, so that the locking assembly in the outer handle locks the outer handle, thereby restricting the rotation of the outer handle and preventing the person outside the door from unlocking the door by turning the outer handle, thereby achieving anti-locking of the door lock; when the door is in the anti-locking state, the anti-locking slide 22 is pulled in the opposite direction. The anti-locking slide 22 drives the anti-locking rotating member 21 to rotate in the opposite direction through the linkage member 23. The anti-locking rotating member 21 drives the linkage plate 3 to rotate in the opposite direction, so that the locking assembly releases the lock of the outer handle, so that the person outside the door can unlock the door by turning the outer handle again;

[0026] The anti-lock rotating member 21 is driven by the anti-lock slide plate 22 and the linkage member 23, so that the anti-lock and unlocking operations of the door lock are smoother, solving the problem that the anti-lock mechanism of the existing door lock is prone to jamming, and the door lock structure is more reasonable.

[0027] The other end of the linkage member 23 is provided with a rotation hole 231, and the anti-locking slide plate 22 is provided with a rotation column 221 adapted to the rotation hole 231; the rotation hole 231 is sleeved on the rotation column 221, so that the linkage member 23 is rotatably set on the anti-locking slide plate 22;

[0028] The length of the linkage long slot 232 is greater than the length of the linkage column 211. When the anti-locking slide plate 22 slides relative to the anti-locking rotating member 21, the linkage member 23 will rotate relative to the anti-locking slide plate 22, causing the linkage column 211 to move back and forth relative to the linkage long slot 232. Under the pull of the linkage member, the linkage column will drive the anti-locking rotating member 21 to rotate in the inner handle 1; that is, when the linkage member 23 pulls the linkage column 211 to drive the anti-locking member to rotate, the linkage column 211 will move back and forth relative to the linkage long slot 232, avoiding jamming and making the anti-locking mechanism run more smoothly.

[0029] A push-pull button 222 is provided on one end of the anti-locking slide 22, and a push-pull window 11 is provided on the lower end surface of the inner handle 1. The push-pull button 222 passes through the push-pull window 11 and is placed at the lower end of the inner handle 1. When locking or unlocking the door lock, hold the inner handle 1 with one hand and gently push or pull the push-pull button 222 of the anti-locking slide 22 to one side with your finger. The operation is simple and convenient.

[0030] The inner handle 1 is provided with a sliding groove 12 for the anti-locking slide plate 22 to slide, so that the anti-locking slide plate 22 can slide smoothly in the inner handle 1, making the structure of the door lock more stable.

[0031] 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.
