When a criminal inserts a technical tool into the keyhole in the outdoor lock core body, the technical tool will push the outdoor lock core body to contact the early warning device ⑨, and the early warning device ⑨ will send out an alarm signal, which can serve as a warning to the criminal, greatly reducing the possibility of further crimes, thereby improving the safety performance. Expandably, when the owner of the door lock inserts the key matching the door lock into the keyhole in the outdoor lock core body, the key will also push the outdoor lock core body to contact the early warning device ⑨, so that the early warning device ⑨ sends out an alarm signal, but since the owner of the door lock is the one who wants to open the door at this time, even if the alarm signal is sent, it will not affect the owner's door opening action, and will not affect the unlocking.

[0021] Specifically, one side of the safety lock core is connected to the indoor area, and the other side is connected to the outdoor area. Taking the side of the safety lock core connected to the indoor area as the indoor side and the side connected to the outdoor area as the outdoor side as an example, the outdoor lock core body is arranged on the outdoor side of the safety lock core, and the lock shaft ④ is arranged on the indoor side of the safety lock core. Furthermore, the outdoor lock core body and the lock shaft ④ are axially arranged, and the center lines are on the same straight line. A keyhole is arranged in the outdoor lock core body, and the extension direction of the keyhole is consistent with the center line direction of the outdoor lock core body and the lock shaft ④, so as to facilitate better unlocking. When a key or technical tool is inserted into the keyhole in the outdoor lock core body, it will push the outdoor lock core body forward toward the indoor side, that is, close to the lock shaft ④. The early warning device ⑨ is set in the lock shaft ④. The specific setting position is not unique. In this embodiment, the early warning device ⑨ can be set at the center line position of the lock shaft ④. When a technical tool or key is inserted into the keyhole, the key or technical tool pushes the outdoor lock core body to approach the lock shaft ④. Since the center lines of the lock shaft ④ and the lock shaft ④ are on the same straight line, when the early warning device ⑨ is set at the center line position of the lock shaft ④, it can more sensitively monitor the approach of the outdoor lock core body, improve the accuracy of the early warning, and further improve the safety performance of the safety lock core. It can be understood that in other embodiments, the early warning device ⑨ can also be set at other positions of the lock shaft ④, as long as the technicians in this field think it can be achieved.

[0022] In one embodiment, see Figure 1 The outdoor lock cylinder body includes the lock core ③ and the clutch There is a key hole and clutch in the lock core ③. Movable connection with lock core ③, clutch The movement direction of the keyhole matches the insertion direction of the technical tool. When a technical tool is inserted into the keyhole, the early warning device ⑨ engages with the clutch part. Or the lock ③ contacts and sends out an alarm signal.

[0023] Specifically, the structure of the outdoor lock core body is not unique. In this embodiment, the outdoor lock core body includes a lock core ③ and a clutch member. , clutch parts Relative to the lock core, position ③ can be moved, the clutch The movement direction of the clutch matches the insertion direction of the technical tool, that is, when the technical tool or key is inserted into the keyhole, the clutch The lock cylinder ③ can also move toward the lock axis ④. When a technical tool or key is inserted into the keyhole, the lock cylinder ③ moves toward the lock axis ④. When the lock cylinder ③ touches the warning device ⑨, it is connected with the warning device ⑨. At this time, the warning device ⑨ sends an alarm signal and sends a prompt message that an object has been inserted into the safety lock cylinder. The lock cylinder ③ can also move toward the lock axis ④. When a technical tool or key is inserted into the keyhole, the lock cylinder ③ moves toward the lock axis ④. When the lock cylinder ③ touches the warning device ⑨, it is connected with the warning device ⑨. At this time, the warning device ⑨ sends an alarm signal and sends a prompt message that an object has been inserted into the safety lock cylinder.

[0024] Lock core ③ and clutch parts The connection method is not unique. For example, the inner wall of the lock core ③ is provided with a groove, and the extension direction of the groove matches the insertion direction of the technical tool or key. The outer surface of the clutch is provided with a protrusion matching the shape, size and extension direction of the groove, and the protrusion can slide in the groove to make the clutch It can move toward the lock shaft ④ or away from the lock shaft ④. It can be understood that in other embodiments, the outdoor lock core body can also be other structures, and the safety lock core can also include other structures, as long as those skilled in the art consider it feasible.

[0025] In one embodiment, the early warning device ⑨ includes a detection device and an alarm component. The detection device is arranged on the lock shaft ④. When a technical tool is inserted into the keyhole, the detection device contacts the outdoor lock core body. The alarm component is connected to the detection device. The alarm component sends an alarm signal when the detection device contacts the outdoor lock core body.

[0026] Specifically, the structure of the early warning device ⑨ is not unique. In this embodiment, the early warning device ⑨ includes a detection device and an alarm component. The alarm component can monitor the contact between the detection device and the outdoor lock core body. When a key or a technical tool is inserted into the keyhole, the key or the technical tool will push the outdoor lock core body forward toward the indoor side, so that the outdoor lock core body contacts the detection device. The outdoor lock core body includes a lock core ③ and a clutch. For example, generally speaking, the clutch The clutch and the detection device are made of conductive materials. When in contact with the detection device, the clutch Connected with the detection device, in the clutch When connected to the detection device, the alarm component sends out an alarm signal. When the early warning device ⑨ includes a detection device and an alarm component, the detection device can detect whether the outdoor lock core body is close to and in contact with it. When the outdoor lock core body contacts the detection device, it means that a key or technical tool has been inserted into the keyhole and has pushed the outdoor lock core body forward. The alarm component can send out an alarm signal when the outdoor lock core body contacts the detection device, which serves to warn lawbreakers and remind the owner of the door lock. The detection device and the alarm component cooperate with each other to improve the safety performance of the safety lock core. It can be understood that in other embodiments, the early warning device ⑨ can also include other structures, as long as those skilled in the art believe that it can be implemented.

[0027] In one embodiment, see Figure 2 and Figure 3 The detection device is a probe, which is arranged in the lock shaft ④. The probe as a detection device can detect whether the outdoor lock cylinder body is approaching. When the outdoor lock cylinder body approaches and contacts the probe, the alarm component sends an alarm signal.

[0028] Specifically, the setting position of the probe is not unique. In this embodiment, a hollow cavity is provided in the lock shaft ④, and the probe is provided in the hollow cavity, which can not only protect the probe, but also reduce the volume of the safety lock core. Further, the setting direction of the probe is not unique. For example, the height direction of the probe is perpendicular to the insertion or withdrawal direction of the technical tool or key. When the technical tool or key pushes the outdoor lock core body close to the lock shaft ④, the probe can detect the approach of the outdoor lock core body on one side close to the outdoor lock core body in the entire height direction, making the detection of the insertion of the key or technical tool more sensitive, facilitating the alarm component to send an alarm signal in time, and improving the working performance of the safety lock core. Expandably, the material of the probe is not unique. For example, the probe can be a copper probe, which has high conductivity, long service life, and low cost of use, which can reduce the cost of use of the safety lock core. The shape of the probe is not unique. For example, the probe can be conical, and the bottom surface of the cone is provided in the lock shaft ④, with a large area and good fixing performance. The conical probe occupies a small volume and has sensitive detection. It is understandable that in other embodiments, the location, material or shape of the probe may be other, as long as those skilled in the art consider it feasible.

[0029] In one embodiment, the number of probes is more than two, and each probe is connected to the alarm component. When the number of probes is more than two, each probe can detect the approach of the outdoor lock cylinder body, thereby improving the detection success rate and reducing the occurrence of missed detection.

[0030] Specifically, the specific number of probes is not unique and can be adjusted by those skilled in the art according to actual conditions. When the number of probes is more than two, the setting position of each probe is not unique either. For example, each probe can be arranged in a row, and the direction of arrangement can be parallel to the direction in which the technical tool or key is inserted into the keyhole. In this case, the depth of the technical tool or key inserted into the keyhole can be determined according to the position of the probe connected to the outdoor lock cylinder body. In an extensible manner, the alarm component can send out different degrees of alarm signals according to the position of the probe connected to the outdoor lock cylinder body. When the outdoor lock cylinder body is only connected to the closest probe, it may be a case of misdetection, or the user accidentally takes the wrong key, and a less severe alarm signal is sent at this time. When the outdoor lock cylinder body is connected to the probe close to the indoor side, considering that the technical tool or key is inserted deeper, the outdoor person really wants to open the door, and a more severe alarm signal is sent to serve as a warning or reminder. Alternatively, each probe can be arranged in a row, and the direction of arrangement can be perpendicular to the direction in which the technical tool or key is inserted into the keyhole. In this case, as long as the outdoor lock cylinder body is close, the probes at each position may be connected to it, thereby improving the sensitivity of detection. It is understandable that in other embodiments, the probes may be arranged in other arrangements and may be adjusted according to actual needs as long as those skilled in the art consider it feasible.

[0031] In one embodiment, the alarm component includes a sound alarm and a light alarm connected to the detection device. When the alarm component includes a sound alarm, a sound can be emitted by the sound alarm, and the sound alarm has a good prompting effect and is convenient to use.

The alarm component can also include a sound alarm and a light alarm at the same time. When a technical tool is inserted into the keyhole, a sound alarm and a light alarm can be issued at the same time, thereby strengthening the alarm effect and improving the working performance of the safety lock core.

[0032] Specifically, the type of sound alarm is not unique. In this embodiment, the sound alarm can be a buzzer, which can realize the alarm function through the alarm sound, or the sound alarm can also send out some preset voice signals, such as "Who are you?", etc., which can have a deterrent effect on criminals. The type of light alarm is not unique either. For example, it can be a prompt light. The type of alarm signal sent by the prompt light is not unique either. For example, it can be the number of prompt lights, the color of the prompt light, or the flashing state of the prompt light, etc., to expand the scope of application of the safety lock core. When the alarm component includes both the sound alarm and the light alarm, the state of cooperation between the two devices can be adjusted according to the needs to improve the working performance of the safety lock core. For example, during the day, the sound alarm can be mainly used to send out the alarm signal, and the alarm effect is obvious. At night, the light alarm can be mainly used to send out the alarm signal. Under the premise of ensuring the alarm effect, it will not disturb the rest of the surrounding users and is convenient to use. It can be understood that in other embodiments, the alarm component can also include other types of devices as long as the technicians in this field think it can be realized.
