The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.

[0019] See also Figures 1 to 3 In an embodiment of the utility model, a self-locking door lock device includes a door panel 2 and a door panel 3, a door lock 5 is provided at the middle position of the door panel 2, the door lock 5 includes a door lock fixing plate 1 501, a door lock fixing plate 2 502 is provided on one side of the door lock fixing plate 1 501, a door lock movable tongue spring 503 is provided between the door lock fixing plate 1 501 and the door lock fixing plate 2 502, a positioning column 504 is provided at one end of the outer side of the door lock movable tongue spring 503, a rotating shaft 505 is provided inside the door lock movable tongue spring 503, a door frame 1 is provided on the outer side of the door panel 1 2 and the door panel 2 3, and a door bolt 7 is provided at the middle position of the door panel 2 3.

[0020] The principle of self-locking door locks is mainly based on mechanical structure and electronic control technology. In terms of mechanical structure, self-locking door locks usually include one or more lock tongues, which can automatically pop out and lock the door frame when the door is closed, thereby locking the door. If the door is not closed, the lock tongue cannot be popped out and the door cannot be locked; this design can prevent unauthorized entry and provide a certain degree of anti-theft function. In terms of electronic control technology, some self-locking door lock systems may include a door magnetic sensor, which can detect whether the door is closed; if the door is closed, the system will automatically pop out the lock tongue and lock the door; if the door is not closed, the system cannot perform the door locking operation; in addition, self-locking door locks may also include an electronic self-locking function, which allows the lock to remain locked under certain conditions even if the operator leaves.

[0021] Please refer to Figure 1 The thickness of the door lock fixing plate 1 501 and the door lock fixing plate 2 502 are both 3-6 mm, the width of the door lock fixing plate 1 501 and the door lock fixing plate 2 502 are both 40-80 mm, and the door lock fixing plate 1 501 and the door lock fixing plate 2 502 are both fixed on the door panel 1 2, which ensures the rigidity of the door lock 5 when in use, thereby increasing the service life of the device.

[0022] Please refer to Figure 1 The top of the door panel 1 2 and the door panel 2 3 are both provided with an observation window 4, which facilitates the observation of the internal and external environment and is highly practical.

[0023] Please refer to Figure 3 The outer side of the door lock movable tongue spring 503 is provided with a bevel, and the angle of the bevel is 40-60 degrees. The inner side of the door lock movable tongue spring 503 is provided with an "L"-shaped bayonet. The bevel facilitates the movement of the door bolt 7, and the L-shaped buckle ensures the firmness of the locking and is more practical.

[0024] Please refer to Figure 2 and 3 The diameter of the positioning column 504 is 4 mm, and the diameter of the rotating shaft 505 is 10-12 mm. The positioning column 504 and the rotating shaft 505 are welded to the door lock fixing plate 1 501 and the door lock fixing plate 2 502. The positioning column 504 limits the door lock active tongue spring 503, and the connection is ensured to be firm through welding.

[0025] Please refer to Figure 1 and 2 The thickness between the door lock fixing plate 1 501 and the door lock fixing plate 2 502 and the door lock movable tongue spring 503 is 2 mm. A through hole is provided inside the door lock movable tongue spring 503, and the diameter of the through hole is 1 mm. The door lock movable tongue spring 503 is rotatably fixed between the door lock fixing plate 1 501 and the door lock fixing plate 2 502 through the rotating shaft 505 and the through hole. The friction is reduced through the gap between each other to increase the service life of the device.

[0026] Please refer to Figure 1 , 2 A clamping block 6 is provided at the middle position of the door bolt 7, and the door bolt 7 is fixed to the door panel 2 3 through the clamping block 6, thereby ensuring the rotation of the door bolt 7 and performing connection and fixing at the same time.

[0027] Please refer to Figure 1 , 2 And 3, the door panel 1 2 is locked and connected with the door panel 2 3 through the door bolt 7 and the door lock movable tongue spring 503, which can realize self-locking and is convenient for use.

[0028] The working principle of the utility model is as follows: when people enter the door, they rotate the bolt 7, the bolt 7 is disengaged from the self-locking of the door lock 5, then they pull open the door panel 1 2 or the door panel 2 3 to enter the building, and then they pull the bolt 7 inside the door, so that the bolt 7 pushes the door lock movable tongue spring 503 to rotate, and the door lock movable tongue spring 503 rotates along the rotating shaft 505 between the door lock fixing plate 1 501 and the door lock fixing plate 2 502, and the bolt 7 enters the L-shaped slot inside the door lock movable tongue spring 503, so that the door lock is self-locking. When people come out of the indoor of the building, they need to rotate the bolt 7 downward and push the door panel outward to walk out. The people who walk out push the door panel to make the bolt 7 enter the L-shaped slot of the door lock movable tongue spring 503, so that the door lock is self-locking. This device is easy to use, simple to operate, and relatively convenient to maintain and install. At the same time, it solves the problems that the door cannot be self-locked after being closed, it is easy to be blown open by wind, and the door panel is damaged, and it is suitable for use with all flat opening doors.

[0029] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
