[0002] With the continuous improvement of social security awareness and the rapid development of smart home technology, the intelligence and security of door lock systems have become important requirements in modern life. Although traditional mechanical locks provide basic protection functions to a certain extent, they have limitations in dealing with illegal intrusions, unexpected situations or diversified user needs, especially in terms of instant notification, remote monitoring and intelligent management.

[0003] In recent years, various types of smart door locks have gradually replaced traditional mechanical locks and become the mainstream choice for homes, offices and even public facilities because they integrate advanced sensor technology, communication technology and control logic, and realize functions such as remote control, real-time alarm, and user identification records. However, there is still room for improvement in the unlocking status monitoring and abnormal alarm of various existing door lock bodies. Although many door lock bodies integrate unlocking functions such as mechanical keys, electronic key verification, and password input, the physical operation monitoring of the lock core itself is not detailed enough, especially in the case of malicious damage, forced prying, etc., it may not be able to notify the user in a timely and accurate manner.

[0004] In response to this technical problem, the present application makes improvements so that users can timely understand the switch lock information of the unlocking core. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example:

[0027] like Figures 1 to 6As shown, the utility model discloses a lock body with unlocking reminder function, including a lock body shell 1, a side panel 2 is fixedly connected to the left side of the lock body shell 1, a lock tongue 3 is slidably connected to the side panel 2, and a mounting cavity 11 is provided in the lock body shell 1, an unlocking rod 4 is provided in the mounting cavity 11, a linkage mechanism is provided between the unlocking rod 4 and the lock tongue 3, and a lock core 5 is fixedly installed on the lock body shell 1, the lock core 5 penetrates into the mounting cavity 11, the lock core 5 includes a rotating part 51 located in the mounting cavity 11, the mounting cavity 11 is provided with a micro switch 6 on the left side of the rotating part 51, and a mounting device for fixing the micro switch 6 is fixedly connected to the lock body shell 1 The unlocking lever 4 is located at the upper left side of the rotating part 51. When the lock tongue 3 is unlocked, the lock cylinder 5 is rotated to rotate the rotating part 51 on the lock cylinder 5 so as to push the unlocking lever 4 upward. The unlocking lever 4 causes the linkage mechanism to drive the lock tongue 3 to retract into the mounting cavity 11 for unlocking. When the lock cylinder 5 is rotated to reset the rotating part 51, the lock tongue 3 is reset, and the linkage mechanism and the unlocking lever 4 are also reset. It should be noted that the lock cylinder 5 is a prior art, and its structure of driving the rotating part 51 to rotate by the key is also a well-known common sense. Its specific structure will not be repeated here, and the linkage mechanism described in the utility model is not limited to the attached Figure 6 As long as the unlocking rod 4 is pushed upward, the lock tongue 3 can be driven to unlock. The unlocking rod 4 and the linkage mechanism are not the content to be protected by the present invention, so the present invention will not focus on describing its structure. The focus to be protected by the present invention is that the rotating part 51 on the lock cylinder 5 must pass through the micro switch 6 during the process of rotating toward the unlocking rod 4. Therefore, when the lock cylinder 5 is unlocked under normal or abnormal conditions, the micro switch 6 will be triggered and send a signal, thereby starting the reminder function.

[0028] Among them, the micro switch 6 includes a switch body 61 and a presser foot 62. In order to facilitate the installation of the micro switch 6, a mounting groove 71 is opened on the side of the mounting frame 7 facing the lock body shell 1. The switch body 61 is fixedly installed in the mounting groove 71, and the presser foot 62 passes through the lock body shell 1 and extends toward the lower side of the unlocking rod 4, so that the rotating part must touch the presser foot 62 when rotating toward the unlocking rod 4, and the presser foot 62 is rotatably connected to the roller 63 on the end close to the unlocking rod 4. The roller 63 is convenient for contacting the rotating part 51 on the lock core 5, thereby improving the service life of the micro switch 6.

[0029] Furthermore, a mounting hole 21 is provided on the side panel 2, and a threaded hole 52 corresponding to the mounting hole 21 is provided on the lock core 5, and a fixed threaded column 8 is provided on the mounting hole 21, and the fixed threaded column 8 is threadedly engaged with the threaded hole 52, so that the lock core 5 is fixed to the lock body shell 1. In addition, a passage groove 72 for the fixed threaded column 8 to pass through is provided on the mounting frame 7, and the fixed threaded column 8 passes through the passage groove 72 to press the mounting frame 7 onto the lock body shell 1, wherein the mounting frame 7 can fix the micro switch 6 well, and the lock core 5 and the mounting frame 7 can be fixed to the lock body shell 1 at the same time through the action of the fixed threaded column 8, achieving the effect of killing two birds with one stone, and the structure is firmly fixed, and can effectively prevent the lock core 5 and the mounting frame 7 from being disassembled and damaged from the outside when the doors and windows installed with the utility model are closed, thereby improving the anti-theft performance of the utility model.

[0030] In order to further improve the firmness of the installation of the mounting frame 7, a positioning column 12 is fixedly connected to the lock body shell 1, and a positioning hole 73 for the positioning column 12 to pass through is opened on the mounting frame 7. The utility model further strengthens the structural strength of the mounting frame 7 fixed to the lock body shell 1 through the provision of the positioning column 12.

[0031] In the utility model, a cover plate 9 is provided on the lock body shell 1, and a plurality of screw hole columns 13 are fixedly connected to the side of the installation cavity 11 of the lock body shell 1. The cover plate 9 is provided with connecting holes 91 corresponding to the screw hole columns 13. The cover plate 9 can be fixed to the lock body shell 1 by passing a screw through the connecting hole 91 and being threadedly connected to the screw hole column 13.

[0032] Among them, a positioning hole 92 is opened on the cover plate 9 for the positioning column 12 to be inserted therein. In addition, an insertion column 74 is fixedly connected to the mounting frame 7. The insertion column 74 and the positioning hole 92 are respectively located on the upper and lower sides of the fixed threaded column 8. Such an arrangement can ensure the firmness of the installation of the mounting frame 7. A first socket 14 is opened on the lock body shell 1 for inserting one end of the insertion column 74, and a second socket 93 is opened on the cover plate 9 for inserting the other end of the insertion column 74. In addition, a resist column 75 is fixedly connected to the mounting frame 7. The resist column 75 is used to contact the cover plate 9. In this way, the mounting frame 7 is firmly and reliably installed between the lock body shell 1 and the cover plate 9, thereby effectively ensuring the stability of the installation of the micro switch 6 and preventing the micro switch 6 from shifting in position, thereby affecting the monitoring of the lock cylinder 5.
