Through the cooperation of the door lock reverse locking reminding device and the lock body 6, the door lock reminding device can remind the reverse locking or unlocking state when the lock body 6 is reverse locked or unlocked.

[0031] as Figures 2 to 7 indicated, a door lock reverse locking reminding device comprises a shell 1 and a rotating disc assembly 2, the rotating disc assembly 2 can rotate circumferentially relative to the shell 1, the rotating disc assembly 2 comprises an inner rotating disc 21 and an outer rotating disc 22, the inner rotating disc 21 can rotate circumferentially relative to the outer rotating disc 22, the shell 1 is provided with a display area 11, the inner rotating disc 21 is provided with a poking column 211, the outer rotating disc 22 comprises display marks 221 and two poking blocks 222 arranged at intervals, the poking column 211 is located between the two poking blocks 222, the poking column 211 can move to a reset position, a reverse locking position and an unlocking position with the rotation of the inner rotating disc 21, when the poking column 211 moves from the reset position to the reverse locking position or the unlocking position, the corresponding poking block 222 is pushed to push the outer rotating disc 22 to rotate and make the display marks 221 move to the display area 11, when the poking column 211 moves from the reverse locking position or the unlocking position to the reset position, the poking column 211 moves from one poking block 222 to the direction close to the other poking block 222. After the present utility model is adopted, since the outer rotating disc can rotate circumferentially relative to the inner rotating disc, the display marks are arranged on the outer rotating disc, the poking column on the inner rotating disc pokes the poking block on the outer rotating disc when the inner rotating disc rotates, so that the outer rotating disc rotates, the display marks appear on the display area of the shell, whether the reverse locking is successful can be confirmed by observing the display marks on the display area, after the inner rotating disc is reset, the outer rotating disc will not move with it, the display marks are still displayed on the display area, it is not necessary to confirm whether the reverse locking is successful repeatedly, time is saved.

[0032] Further, the toggle block 222 is provided with a notch 2221 matched with the toggle column 211. When the toggle column 211 moves from the anti-lock position or the unlock position to the reset position, the toggle column 211 moves from abutting one toggle block 222 to abutting another toggle block 222. When in the reset position, the toggle column 211 abuts the other toggle block 222, and there is no idle stroke between the toggle block 222 and the toggle column 211, and it is easier to perform anti-locking or unlocking next time.

[0033] As a specific embodiment, but not limited, in order to make the door handle 4 automatically reset after rotating anti-locking or unlocking, the door handle 4 is detachably fixed with the inner rotating disc 21, and the shell 1 is provided with an elastic member 3 for resetting the inner rotating disc 21 after rotating. The shell 1 is provided with an abutting column 12, and the inner rotating disc 21 is provided with an abutting block 212, and the elastic member 3 extends with elastic ribs 31 respectively abutting the abutting block 212 and the abutting column 12. Since the door handle 4 is fixed with the inner rotating disc 21, the shell 1 is fixed on the door, and the two ends of the elastic member 3 extend with elastic ribs 31, and each elastic rib 31 abuts the abutting block 212 and the abutting column 12 in turn. When the door handle is lifted or pressed, the door handle 4 drives the inner rotating disc 21 to rotate, and at this time, the elastic ribs 31 and the elastic member 3 have a restoring force to make the inner rotating disc 21 have a tendency to return to the original position, and when the door handle 4 is released, the door handle 4 will automatically reset. The toggle column 211 is arranged between the two toggle blocks 222. For example, when the door handle 4 is lifted to the anti-locking state, the toggle column 211 toggles one of the two toggle blocks 222, so that the outer rotating disc 22 rotates clockwise, and the display mark 221 is divided into an unlocking display mark and an anti-locking display mark. The outer rotating disc 22 rotates counterclockwise, and the anti-locking display mark 221 is displayed on the display area 11, so that the state of the door lock can be known by observing the display mark 221. When the door handle 4 is released, the door handle 4 returns to the original position, and since the two toggle blocks 222 form an adjustment stroke 225, the outer rotating disc 22 will not be toggled when the door handle 4 resets, so that the display mark 221 can always stay at the anti-locking display mark. When unlocking is needed, the door handle 4 is pressed to make the toggle column 221 toggle the other toggle block 222 to drive the outer rotating disc 22 to rotate clockwise, so that the unlocking display mark 221 is displayed on the display area 222. Alternatively, the two toggle blocks 222 can also be symmetrically arranged on the other side of the outer rotating disc 22, for adapting to the installation orientation of the door in different directions.

[0034] Furthermore, to better detect the locking or unlocking of the door, the outer turntable 22 has a mounting groove 223 on its side wall. A limiting component 224 for positioning is provided within the mounting groove 223. The outer casing 1 has multiple limiting grooves 13 distributed circumferentially along its inner wall. When the outer turntable 22 rotates relative to the outer casing 1, the limiting component 224 can engage or disengage from the corresponding limiting groove 13. The limiting groove 13 is a hemispherical groove. The limiting component 224 includes a limiting spring 2241 and a limiting ball 2242. The limiting ball 2242 is located at one end of the limiting spring 2241, and the other end of the limiting spring 2241 is fixed to the bottom of the mounting groove 223. The outer casing 1 is provided with multiple limiting grooves 13, and the outer turntable 22 is provided with a limiting component 224. The limiting component 224 is composed of a limiting spring 2241 and a limiting ball 2242. When the outer turntable 22 rotates, the limiting spring 2241 will push out the limiting ball 2242 and engage it with the limiting groove. At this time, the rotation of the outer turntable 22 will be restricted, and the operator will feel whether it is locked or unlocked, which is more tactile and has a better operating experience.

[0035] As a specific implementation and not a limitation, to prevent the inner turntable 21 from rotating beyond its range under the influence of the door handle 4, the inner turntable 21 is provided with a limiting wall 214. The limiting wall 214 cooperates with the abutment post 12 to limit the rotational travel of the inner turntable 21. When the door handle 4 is lifted or pressed down, the inner turntable 21 rotates. When it rotates to the point where the limiting wall 214 abuts against the abutment post 12, the abutment post 12 restricts the rotation of the inner turntable 21, ensuring that the rotation of the inner turntable 21 does not exceed its rotational travel.

[0036] Furthermore, to facilitate the installation and fixation of the door handle 4 and the inner turntable 12, a groove 41 is provided on the front side wall of the door handle 4, and a plug-in block 213 is provided on the inner turntable 21. The plug-in block 213 cooperates with the groove 41 for fixation. A fixing ring 5 is included, and an annular groove 42 is provided at the front end of the door handle 4. The fixing ring 5 is used to cooperate with the annular groove 42 and fix the inner turntable 21 along the axial direction of the door handle 4. When installation is required, simply insert the plug-in block 213 along the groove 41 to restrict the inner turntable 21 from rotating along the circumferential direction of the door handle 4, and then install the fixing ring 5 into the annular groove 42 to fix the door handle 4 to the inner turntable 21.

[0037] The specific working principle of this embodiment is as follows: Figures 8 to 11 As shown in the diagram, the direction of the arrow indicates the direction in which the inner turntable will rotate. Figure 8 As shown, when the toggle switch is in the reset position, the display area shows the unlock indicator. When it is necessary to lock, as shown... Figure 9As shown by the upper door handle, the door lock is in the anti-lock state, the door handle drives the inner disc to rotate counterclockwise, the inner disc is provided with a dialing column, the dialing column is rotated to the anti-lock position, and the dialing column is abutted with the dialing block of the outer disc to drive the outer disc to rotate, the outer disc is provided with a display mark, the outer disc drives the anti-lock display mark to the display area, and the door handle is released. Figure 10 As shown, the door handle is automatically reset by the elastic element, the dialing column is rotated to the reset position, the outer disc is not moved at this time, and the display area still displays the anti-lock display mark.
