[0002] In daily life, doors are important partitions and passages between indoor and outdoor areas. The correct and safe opening and closing of doors is crucial to ensuring personnel safety, maintaining the indoor environment, and preventing accidents. However, traditional door closing methods often rely on door locks or simple latch mechanisms, which may not be able to effectively prevent doors from closing accidentally when faced with some uncontrollable external factors.

[0003] Especially in windy weather conditions, strong winds can sometimes overcome the resistance of door locks or latches, causing the door to close unexpectedly, which can cause inconvenience to people inside and may even cause safety hazards. In addition, for families with children or pets, the door closing unexpectedly may also bring additional risks, such as children being trapped indoors and pets being unable to enter and exit in time.

[0004] In order to solve this problem, people began to explore various door closing auxiliary devices, aiming to provide a solution that can enhance the stability of the door and prevent accidental closing. However, existing devices often have problems such as complex structure, inconvenient installation, cumbersome operation or poor effect, and cannot meet people's comprehensive needs for safety, convenience and reliability.

[0026] Combined with Figure 1 To Attachment Figure 5As shown, this embodiment provides a door closing confirmation device, including a card plate 3, which is clamped on the upper part of the door panel 1. The card plate 3 is provided with a plurality of screw holes and is fixedly connected to the door panel 1 by screws. The card plate 3 is fixedly connected to a positioning tube 4 with a closed bottom on the inner side of the door panel 1. The top of the positioning tube 4 is lower than the top of the door panel 1. A top rod 5 is sleeved inside the positioning tube 4. A spring 6 is provided between the bottom of the top rod 5 and the bottom of the positioning tube 4. A wire through hole is provided at the bottom of the positioning tube 4. The pull rope is fixedly connected to the bottom of the top rod 5 and passes through the spring 6 and the wire through hole.

[0027] It can be understood that the present embodiment provides a door closing confirmation device, including a card plate 3 that is clamped on the upper part of the door panel 1, and the card plate 3 is provided with a plurality of screw holes, the screw holes including a first screw hole 11 that is provided on the card plate 3 and located on the inner side of the door panel 1 and a second screw hole 14 that is located on the outer side of the door panel 1, and is fixedly connected to the door panel 1 by fasteners such as screws, so that the device can be firmly installed on the door and will not fall off easily due to the use of the door or external factors. A bottom-closed positioning tube 4 is fixedly connected to the inner part of the door panel 1 of the card plate 3, and the top of the positioning tube 4 is designed to be lower than the top of the door panel 1 to ensure that there is no interference with the door frame when the device is working. A push rod 5 is sleeved inside the positioning tube 4, and the push rod 5 can move up and down in the positioning tube 4. A spring 6 is provided between the bottom of the push rod 5 and the bottom of the positioning tube 4, and the function of the spring 6 is to provide an upward thrust for the push rod 5, so that it can remain in a state of extending out of the positioning tube 4 when there is no external force. The bottom of the positioning tube 4 is also designed with a wire through hole, which allows a pull rope to pass through. One end of the pull rope is fixedly connected to the bottom of the top rod 5, and the other end passes through the spring 6 and the wire through hole and extends to the outside of the positioning tube 4. When the user needs to close the door, the pull rope can be pulled to overcome the thrust of the spring 6 to retract the top rod 5 into the positioning tube 4, thereby allowing the door to close. When external force (such as strong wind, etc.) tries to close the door, the top rod 5 will extend out of the positioning tube 4 under the action of the spring 6, blocking the closing of the door, thereby preventing accidents. The present invention provides a door closing confirmation device, which is installed at the upper end of the door. When the pull rope is not subjected to tension, the push rod 5 extends out of the positioning tube 4 under the action of the spring 6, and the push rod 5 is stuck on the outside of the door frame. At this time, the door cannot be closed; when the pull rope is subjected to force and the force is greater than the resistance of the spring 6, the push rod 5 is pulled into the positioning tube 4, and the door can be closed. This solution completely blocks the possibility of closing the door due to external factors such as strong wind other than human power, so that there are more opportunities and possibilities to discover dangerous sources such as children playing near the door, so as to achieve the purpose of safely closing the door.
