[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] See also Figure 1-4 , which is a dual-function lock reminder device described in the present invention, includes an inner door panel body 11 and a lock handle 12 rotatably arranged on the inner door panel body 11, and the door panel body 11 is provided with a keyhole 14 and an anti-lock knob 15 below the lock handle 12.

[0031] The main innovation of the present invention is that a display window 13 is provided on the inner door panel body 11 above the lock handle 12, and a display window back plate 22 is provided on the back of the display window 13, and a movable display panel 16 is provided between the display window 13 and the display window back plate 22. A reminder mark 17 is provided on the upper part of the front side of the display panel 16 (or a reminder mark is provided on the entire part), such as a reminder word or a key, etc.

[0032] Two tension springs 24 are symmetrically fixed to the upper edge of the display panel 16 . The upper ends of the two tension springs 24 are respectively fixed to two tension spring brackets 23 provided on the inner door panel body 11 , and the lower ends are respectively fixed to the left and right sides of the upper side of the display panel 16 .

[0033] The inner door panel body 11 is provided with a one-way rotating wheel 28 between the two tension springs 24, and a bell spring 29 fixedly connected to the display board 16 is provided above the display board 16. When the bell spring 29 moves downward with the display board 16, the bell spring 29 can touch the one-way rotating wheel 28 to make a sound.

[0034] A rotating wheel 25 coaxial with the handle shaft 21 is provided on the handle shaft 21 rotatably connected to the lock handle 12 and the inner door panel body 11. As described in this embodiment, the rotating wheel 25 is sleeved on the outer periphery of the handle shaft 21, and a connecting rod is provided at the center of the rotating wheel 25 and crosses the center of the handle shaft 21, thereby realizing a coaxial fixed connection between the two.

[0035] A pull rope guide shaft 27 is fixed to the inner door panel body 11 between the rotating wheel 25 and the display panel 16. A pull rope 26 is also provided, one end of which is fixed in a groove provided at the edge of the rotating wheel 25, and the other end of which is fixedly connected to the display panel 16 after passing through the pull rope guide shaft 27. The pull rope 26 can be made of steel wire rope or other materials with good flexibility and rigidity.

[0036] The dual-function lock reminder device can be installed by using the lock handle to open the door with the right hand (see Figure 1-4 ), or the lock handle left-hand door installation method (see Figure 5 ), the specific working principle when used is as follows:

[0037] See also Figure 1-4 , the installation method of the lock handle opening the door with the right hand is explained, refer to Figure 1 , 3 , which are front and back state diagrams of the present invention before the door is opened. At this time, the display panel 16 is subjected to the tension of the two tension springs 24 above, and the portion with the reminder mark 17 located in the upper half (or the entire display panel) is located above the display window 13. At this time, the user cannot see the reminder mark 17.

[0038] When the user goes out, before opening the door, he presses the lock handle 12, and the handle shaft 21 drives the rotating wheel 25 to rotate, and the pull rope 26 connected to the rotating wheel 25 pulls the display panel 16 to move downward, and at the same time, the bell shrapnel 29 connected to the display panel 16 moves downward synchronously. When the lock handle 12 is pressed to the door opening state, the bell shrapnel 29 connected to the display panel 16 moves to the one-way rotating wheel 28, collides with it, and makes a sound, and at the same time, the text or key on the reminder mark 17 on the display panel 16 moves to the display window 13, and the operator (user) can see the reminder of the key or the key set there in the display window 13, so that the operator (user) is reminded not to forget to bring the key when going out through the dual functions of the ringtone and the text or key.

[0039] After opening the door, release the lock handle, the lock handle rebounds, and the linkage structure moves in the opposite direction under the action of two tension springs, and the lock returns to the state before the operation.

[0040] If the lock needs to be interchangeable between left and right hands, such as using the lock handle to open the door with the left hand, refer to Figure 5 , it is sufficient to just wrap the draw rope around the left or right side of the draw rope guide shaft 27 in the left-hand direction.

[0041] It can be seen that the dual-function lock reminder device has the following advantages compared with the prior art:

[0042] 1) When the user goes out, he only needs to press the lock handle to open the door, and a ring tone and text or key movement display will remind the user not to forget to bring the key when going out. This reminds the user both auditorily and visually, which is simple and effective.

[0043] 2) The present invention is applicable to any type of door lock, does not conflict with the original structure of the door lock, and does not hinder the function of the door lock itself;

[0044] 3) The present invention also solves the problem that the lock handle can still function normally after being interchanged between left and right.

[0045] In summary, the present invention adds a reminder function to the existing lock structure, and when the user goes out, it can remind the user both auditorily and visually, thereby simply and effectively preventing the user from forgetting the key. At the same time, it has the advantages of simple structure, easy operation, and low manufacturing cost.

[0046] Many specific details are described in the above description to facilitate a full understanding of the present invention. However, the above description is only a preferred embodiment of the present invention. The present invention can be implemented in many other ways different from those described herein, so the present invention is not limited to the specific implementation disclosed above. At the same time, any person familiar with the art can make many possible changes and modifications to the technical solution of the present invention using the methods and technical contents disclosed above without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of protection of the technical solution of the present invention.
