[0014] A usage method of a door body and wall connection structure for decoration includes the following steps: S1: Install a plurality of connecting hinges equipped with self-adjusting torsion mechanisms and monitoring and display mechanisms between the door frame and the door panel by screws. Specifically, there are a plurality of mounting holes on the surfaces of the door leaf of the door body and the door frame leaf, and screws are provided inside the mounting holes, so that the door leaf of the door body is fixedly connected to the door panel and the door frame leaf is fixedly connected to the door frame through screws, and the upper and lower ends between the door leaf of the door body and the door frame leaf are rotatably connected through a first pin and a second pin respectively; S2: When the door panel is opened, the door panel is attracted and fixed to the wall by the door suction. At this time, the torsion value of the spring is the largest. When the door panel is closed, the door panel is separated from the wall by the door suction, and the door leaf of the door body in the connecting hinge rotates relative to the door frame leaf. Then, the door leaf drives the limit block and the pressure sensor to rotate relative to the spring. At this time, the spring can push the pressure sensor under the limiting action of the positioning block fixedly provided at the upper end of the multi-sided transmission sleeve and gradually reduce its own torsion value; S3: The spring can assist the rotation of the door panel during closing, reduce the closing force of the door panel, and facilitate the door panel to be attracted by the magnet provided inside the lock box and the lock body to achieve the automatic closing effect of the door panel. One end of the pressure sensor is provided with a contact head, and the upper end of the spring is inserted into the inner side of the positioning groove and is in close contact with the contact head. Then, the pressure sensor can monitor the torsion value of the spring through the contact head; S4: When the torsion value of the spring is lower than the first set value when the door panel is opened, a red light is displayed through the display lamp to facilitate reminder operations and at the same time start the motor. The motor drives the transmission column to rotate under the support of the door frame leaf. The transmission column is threadedly connected to the multi-sided transmission sleeve. Then, the transmission column drives the multi-sided transmission sleeve to linearly slide inside the fixed base and pushes the spring to contract through the positioning block, thereby facilitating the automatic adjustment of the elastic force of the spring and keeping the auxiliary force for closing the door panel unchanged; S5: When the torsion value of the spring is lower than the second set value when the door panel is closed, a white light is displayed through the display lamp. At this time, the door panel is manually opened to provide sufficient operating space. The locking rod and the first pin are disassembled, and the guide post is pulled out from the inside of the first pin. Then, the limit block slides and separates relative to the door leaf of the door body, facilitating the disassembly and replacement of the spring and maintaining the auxiliary closing effect of the spring on the door panel.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the door panel is fixed to the wall by the door suction in the present invention, the torsion value of the spring is the largest. When closing the door panel, the door panel is separated from the wall by the door suction. The door body blade drives the limit block and the pressure sensor to rotate relative to the spring. At this time, under the limiting action of the positioning block fixedly arranged at the upper end of the multi-sided transmission sleeve, the spring can push the pressure sensor and gradually reduce its own torsion value. The spring can assist the rotation of the door panel when closing, reduce the closing force of the door panel, and facilitate the door panel to be attracted by the magnet arranged inside the lock box and the lock body, realizing the automatic closing effect of the door panel; 2. In the present invention, the pressure sensor can monitor the torsion value of the spring through the contact. When the torsion value of the spring is lower than the first set value of the pressure sensor when the door panel is opened, the display lamp displays red light for reminder operation. The motor drives the multi-sided transmission sleeve through the transmission column to push the spring to contract through the positioning block, thereby facilitating the automatic adjustment of the elastic force of the spring and keeping the auxiliary force for closing the door panel unchanged. When the torsion value of the spring is lower than the second set value when the door panel is closed, the display lamp displays white light, the locking rod and the first pin are disassembled, and the guide column is pulled out from the inside of the first pin, facilitating the disassembly and replacement of the spring and maintaining the auxiliary closing effect of the spring on the door panel.
