[0028] The technical solutions in the embodiments of the utility model will be apparently and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the protection scope of the utility model.

[0029] Reference Figure 1-3 And Figure 5 A door lock for reminding of not closing door, including: housing 1, one side of the housing 1 is provided with mounting groove 11, lock tongue 2, elastic retractable setting in the mounting groove 11, the lock tongue 2 relative to the housing 1 can be inserted into mounting groove 11 and extend out mounting groove 11, marking piece 3, setting in the outer wall of the lock tongue 2 near mounting groove 11 one end, first sensor 4, setting in the mounting groove 11, for detecting whether the lock tongue 2 is completely extended the mounting groove 11, second sensor 5, setting in the mounting groove 11, for detecting whether the lock tongue 2 is completely retracted the mounting groove 11, execution piece 6, setting in the housing 1, for alarming, controller, with first sensor 4, second sensor 5 and execution piece 6 electric connection, when satisfying the second sensor 5 and the first sensor 4 in turn respectively detect the lock tongue 2 retraction and extend the mounting groove 11 condition, the controller does not control the execution piece 6 work, not satisfying the condition, the controller controls execution piece 6 work.

[0030] It can be understood that the first sensor 4 and the second sensor 5 can be laser or infrared sensors, and the marker 3 is a radiation plate; the first sensor 4 and the second sensor 5 can also be magnetic sensors or inductive sensors, and the marker 3 is a metal sheet or a magnetic material, but not limited to this. The execution member 6 can emit light alarm using an LED lamp, can also use a loudspeaker to generate an alarm, and of course can also be connected to a mobile phone APP for wireless alarm, but not limited to this. The controller can be an AND logic gate, the first sensor 4 and the second sensor 5 are two input ends, and an output end is set, and the output is the execution member 6. Only when both input ends are high level, the output will be high level, and then the execution member 6 alarm work. Of course, the controller can also use a microcontroller, and the output ends of the first sensor 4 and the second sensor 5 are connected to different GPIO pins of the microcontroller; and the program is written to check the state of the two pins. Only when the first sensor 4 and the second sensor 5 detect the marker point (i.e. both GPIO pins read high level), the execution member 6 alarm work is triggered by another GPIO pin output signal, but not limited to this.

[0031] In this way, when the door is closed, the second sensor 5 and the first sensor 4 can detect whether the lock tongue 2 has made the work of retracting the installation groove 11 and extending the installation groove 11 in turn. When the lock tongue 2 does not meet the condition of retracting and extending in turn, it means that the lock tongue 2 is not completely locked, and the controller controls the execution member 6 to alarm and remind. When the lock tongue 2 meets the condition of retracting and extending in turn, it means that the lock tongue 2 has been locked, and the execution member 6 does not alarm and remind. In this way, it can be truly detected whether the door is closed, and the safety of the user is guaranteed.

[0032] In some embodiments, referring to Figure 2-3 , the first sensor 4 corresponds to the marker 3 when the lock tongue 2 completely extends the installation groove 11. Further, the second sensor 5 is arranged on the side of the first sensor 4 close to the deep part of the installation groove 11, and the second sensor 5 corresponds to the marker 3 when the lock tongue 2 completely retracts the installation groove 11. Further, the first sensor 4 and the second sensor 5 are magnetic sensors, and the marker 3 is a magnet. In this way, the first sensor 4 and the second sensor 5 are non-contact inductive. And the positions of the first sensor 4 and the second sensor 5 are fixed. Only when the lock tongue 2 is completely retracted and completely extended, the marker 3 can be detected, and the accuracy of the position detection of the lock tongue 2 is ensured.

[0033] In some embodiments, referring to Figure 4The installation groove 11 is further provided with an abutting piece 7, and a spring 8 is connected between the abutting piece 7 and the lock tongue 2. Further, the second sensor 5 is a pressure sensor and is arranged on the abutting piece 7 and is used for detecting the spring pressure. Here, the abutting piece 7 can be a block structure or a disc structure, and a guide rod or an extension rod can be further arranged on the block structure. In the process of retracting the lock tongue 2, the spring 8 is compressed, the spring pressure acts on the pressure sensor, and the deeper the lock tongue 2 is retracted, the greater the spring pressure on the pressure sensor is, but when a certain pressure value is reached, it represents that the lock tongue 2 is completely retracted. In this way, the retracting state of the lock tongue 2 can also be determined.

[0034] Preferably, the executing piece 6 is a display lamp and / or a sound emitter. Here, the executing piece 6 can be arranged at a more conspicuous position, for example, on a handle or on a door panel with a height adapted to the eye level of a person.

[0035] The above is only a preferred specific implementation of the present application; however, the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes to the technical range disclosed in the present application according to the technical scheme and the improvement concept of the present application, and all of them should be covered in the protection scope of the present application.
