Detailed implementation manners

[0030] Refer to the attached Figures 1 to 9 A further detailed description is given to an ecological door lock of the present utility model.

[0031] An ecological door lock includes an inner handle 3 and an outer handle 4. The inner handle 3 is rotatably arranged on the inner base 1, the outer handle 4 is rotatably arranged on the outer base 2, and the inner handle 3 and the outer handle 4 are connected by a square shaft 6; an anti-lock component 31 is installed inside the inner handle 3, a locking component 41 is installed inside the outer handle 4, and the anti-lock component 31 is linked with the locking component 41 through a linkage plate 5; the anti-lock component 31 and the locking component 41 of this door lock are respectively arranged inside the inner handle 3 and the outer handle 4, reasonably utilizing the installation space of the door handle and simplifying the door lock structure; that is, it replaces the original setting method of arranging the locking component 41 and the anti-lock component 31 inside the lock body, can simplify the lock body structure and reduce the overall volume of the door lock; making the overall door lock structure simpler and the appearance more concise;

[0032] The anti-lock component 31 includes an anti-lock rotating member 311 rotatably disposed in the inner handle 3 and an anti-lock push plate 312 slidably disposed on the inner handle 3; one end of the anti-lock rotating member 311 is connected to the linkage plate 5, and the other end is linked to the anti-lock push plate 312 through a linkage rod 313; the anti-lock push plate 312 drives the anti-lock rotating member 311 to rotate, and the anti-lock rotating member 311 drives the locking component 41 through the linkage plate 5 to restrict the rotation of the outer handle 4; when performing the door lock anti-lock operation, only need to push the anti-lock push plate 312 to one side, the anti-lock push plate 312 drives the anti-lock rotating member 311 to rotate through the linkage rod 313, and the anti-lock rotating member 311 drives the linkage plate 5 to rotate, so that the locking component 41 restricts the rotation of the outer handle 4; thus preventing people outside the door from unlocking the door by rotating the outer handle 4; replacing the existing door lock's anti-lock operation by rotating a knob, which simplifies the anti-lock operation method.

[0033] One end of the anti-lock rotating member 311 opposite to the anti-lock push plate 312 is eccentrically provided with a first connecting column 3111, a first connecting hole at one end of the linkage rod 313 is rotatably disposed on the first connecting column 3111, and a second connecting hole at the other end is rotatably disposed on the second connecting column 3121 of the anti-lock push plate 312;

[0034] Pushing the anti-lock push plate 312 to slide relative to the anti-lock rotating member 311, the linkage rod 313 rotatably disposed on the anti-lock push plate 312 will move towards the anti-lock rotating member 311 under the push of the anti-lock push plate 312, and at the same time rotate relative to the anti-lock push plate 312 around the second connecting column 3121; during the process of moving towards the anti-lock rotating member 311, the linkage rod 313 pushes the anti-lock rotating member 311 to rotate, and at the same time rotates around the first connecting column 3111, converting the linear motion of the anti-lock push plate 312 into the rotational motion of the anti-lock rotating member 311;

[0035] Similarly, when pushing the anti-lock push plate 312 in the reverse direction, the anti-lock push plate 312 will pull the linkage rod 313 to move, driving the linkage rod 313 to drive the anti-lock rotating member 311 to rotate in the reverse direction, so that the anti-lock rotating member 311 drives the locking component 41 through the linkage plate 5 to release the lock on the outer handle 4.

[0036] One end of the anti-lock push plate 312 is provided with a pushing portion 3122, and a pushing and pulling window 32 is provided on the lower end surface of the inner handle 3, and the pushing portion 3122 passes through the pushing and pulling window 32 and is placed at the lower end of the inner handle 3; when performing the anti-lock or unlocking of the door lock, hold the inner handle 3 with one hand and gently push the pushing portion 3122 of the anti-lock push plate 312 to one side with a finger, which is simple and convenient to operate.

[0037] The inner handle 3 is provided with a chute 33 for the anti-lock push plate 312 to slide, enabling the anti-lock push plate 312 to slide smoothly on the inner handle 3 and making the structure of the door lock more stable.

[0038] The locking assembly 41 includes a square shaft sleeve 411, a locking cam 412, and locking balls that cooperate with the locking cam 412. One end of the square shaft sleeve 411 is fixedly connected to the outer handle 4, and the other end passes through the outer base 2 and is connected to the square shaft 6. The locking cam 412 is rotatably arranged in the square shaft sleeve 411, and one end of the locking cam 412 is connected to the linkage plate 5.

[0039] When the linkage plate 5 drives the locking cam 412 to rotate, the locking cam 412 causes the locking balls to be extruded outward, so that a part of the locking balls passes through the ball holes 4111 of the square shaft sleeve 411 and is placed in the locking grooves 21 of the outer base 2, locking the outer handle 4 on the locking seat to restrict the rotation of the outer handle 4 on the outer base 2, preventing people outside the door from rotating the outer handle 4 and thus unable to perform the door opening operation. At the same time, the inner handle 3 and the outer handle 4 are connected by the square shaft 6, and the inner handle 3 is also locked.

[0040] The locking cam 412 is provided with two cam surfaces 4121 adapted to the locking balls, and the cam surfaces 4121 are symmetrically arranged on the locking cam 412. When the linkage plate 5 drives the locking cam 412 to rotate, the cam surfaces 4121 extrude the locking balls outward.

[0041] The other end of the locking cam 412 is connected to the lock core 7, so that when the door lock is anti-locked, people outside the door can insert the door lock key into the lock core 7 and rotate the locking cam 412 to perform anti-locking or unlocking operations.

[0042] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea 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.
