The motor linkage gear is engaged with the motor driving gear 201 of the motor shaft of the motor, or the motor shaft of the motor is directly connected with the motor linkage gear. The tooth openings on the opposite sides of the tightening pulling rack and the door opening and closing swing rod rack are engaged with the gear rings on the two sides of the motor linkage gear at the same time. The motor is connected with the PCB circuit board 16 in the base of the automatic opening and closing tightening mechanism through a circuit. The two ends of the door opening and closing swing rod rack are respectively provided with a door opening and closing swing rod rack spring. The other side of the cabinet is provided with an upper lock catch assembly 22 and a lower lock catch assembly 25 above and below the door opening respectively. The cabinet door opening between the upper lock catch assembly and the lower lock catch assembly is provided with a lock pull rod 24. The steel wire rope 15 extending from one side of the base of the automatic opening and closing tightening mechanism passes through the guide and the tension screw of the lock pull rod at the end corner of the cabinet door opening at the same time. One end of the steel wire rope is connected with the swing lock tongue in the upper lock catch assembly and the lower lock catch assembly through a change of direction or a branch. The door panel of the door assembly corresponding to the upper lock catch assembly and the lower lock catch assembly is provided with a lock catch 2702. The other end of the steel wire rope is connected with one end of the tightening pulling sliding block 17 in the base of the automatic opening and closing tightening mechanism through the guide and the guide block 13. The other end of the tightening pulling sliding block is provided with a tightening pulling sliding block spring. The guide block is fixedly arranged in the base of the automatic opening and closing tightening mechanism. One end of the tightening pulling rack on one side of the cabinet door opening and closing swing rod is provided with a protruding square head 601. The tightening pulling sliding block above the square head is provided with a protruding lock tongue block 27. The rear part of the lock tongue block in the tightening pulling sliding block is provided with a lock tongue block spring. In the initial state, the square head of the tightening pulling rack is located on one side of the vertical edge of the lock tongue block. The end corner on the other side of the vertical edge of the lock tongue block is an inclined end corner. The two ends of the steel wire rope between the extending side of the steel wire rope and the guide block in the base of the automatic opening and closing tightening mechanism are connected through the steel wire rope tension spring 14.

[0031] Meanwhile, the tooth openings of the switch door gear and the switch door swing rack at the swing lever of the cabinet door switch are symmetrically engaged, and a sub rack 5 is arranged in the groove at the other end of the switch door swing rack. A sub rack spring is arranged in the groove at the corresponding side of the sub rack on the side of the steel wire rope extending out of the base. A section of reverse belt idle gap 401 is arranged at the tooth opening of the motor linkage gear at one side of the switch door swing rack. A door closing detection switch 12 is arranged in the base at the swing lever of the cabinet door switch, which is triggered when the swing lever of the cabinet door switch is closed. A door opening detection switch 18 is arranged in the base at the tightening pulling sliding block, which is triggered when the swing lever of the cabinet door switch is opened. A steel wire rope tightening detection switch 19 is arranged in the base at the tightening pulling rack, which is triggered when the tightening pulling rack tightens the steel wire rope. A sealing strip 23 is arranged at the door opening of the cabinet. Support seats 26 are arranged at the bottom corners of the cabinet. The PCB circuit board is provided with an infrared module. The upper and lower lock catch assemblies are retractable locks driven by the steel wire rope.

[0032] The cabinet door sends an opening or closing signal to the lock through an infrared signal. The opening and closing working principles are as follows: after receiving an opening instruction, the motor works to drive the steel wire rope retractable lock to unlock. After the retractable lock is unlocked, the motor drives the cabinet door switch swing lever to work to open the door assembly in the specified direction. After receiving a closing instruction, the motor works to drive the connecting rod to close the cabinet door, and then drives the retractable lock to lock, thereby completing the locking and closing work.

[0033] The specific operation of the cabinet door is as follows: when the door panel of the door assembly is closed by the cabinet door switch swing lever, the motor drives the motor linkage gear to rotate. The motor linkage gear drives the tightening pulling rack and the switch door swing rack to move in the opposite direction at the same time. The square head of the tightening pulling rack abuts against the vertical edge of the lock tongue block to drive the tightening pulling sliding block to move and tighten the steel wire rope. At the same time, the steel wire rope tightens to open the swing lock tongue in the upper and lower lock catch assemblies. Until the lock catch of the door panel is inserted into the swing lock tongue fixed in the upper and lower lock catch assemblies, the swing lock tongue is reset, and the door assembly is closed. The motor continues to drive the motor linkage gear to rotate. The square head of the tightening pulling rack passes the vertical edge of the lock tongue block. The tightening pulling rack is reset and retracted by the tightening pulling rack spring. The steel wire rope is loosened and reset. When the door panel of the door assembly is opened by the cabinet door switch swing lever, the motor drives the motor linkage gear to rotate in the opposite direction. The square head of the tightening pulling rack passes the inclined corner of the lock tongue block. The motor linkage gear rotates in the forward direction again to drive the tightening pulling sliding block to move and tighten the steel wire rope. The lock catch of the door panel is separated from the swing lock tongue in the upper and lower lock catch assemblies. At the same time, the motor linkage gear rotates in the opposite direction again until the door assembly is opened.

[0034] And further, in the case of the above-mentioned steel wire spring: when the door plate of the door assembly is closed by the cabinet door switch swing lever, the steel wire spring is pre-stretched, the lock piece of the door plate is directly inserted into the swing lock tongue of the upper and lower lock catch assemblies and is locked after swinging, and the steel wire spring is stretched and reset until the door assembly is closed, and the cabinet door switch swing lever triggers the door closing detection switch; when the door plate of the door assembly is opened by the cabinet door switch swing lever, the square head of the tightening pull rack is abutted against the vertical edge of the lock tongue block to drive the tightening pull block to move and tighten the steel wire and the steel wire spring, and then the steel wire and the steel wire spring continue to be tightened and trigger the door opening detection switch through the tightening pull block, the lock piece of the door plate is separated from the swing lock tongue of the upper and lower lock catch assemblies, and at the same time, the tightening pull rack is reset and withdrawn through the tightening pull rack spring, the square head of the tightening pull rack is over the vertical edge of the lock tongue block, and the door assembly is opened.

[0035] In summary, the cabinet door has the following advantages: 1. It has a quick unlocking function when the door is opened; 2. When closing the cabinet door, the door needs to be closed first and then tightened; 3. It is controlled by a motor gear box, a remote arm and a connecting rod to open and close left and right; 4. The tightening lock connection method adopts a steel wire connection method; 5. The opening and closing of the door needs to unlock the telescopic lock first, and then open the cabinet door, and the closing needs to close the door first, and then the telescopic lock is tightened to close the door.
