A pulley 35 is rotatably connected to the surface of the adjustment plate 33. The mounting plate 31 and the adjustment... The surface of plate 33 is provided with adjustment grooves 36, and the interior of adjustment grooves 36 is rotatably connected with fixing bolts 37. The mounting frame 2 is provided with a mounting structure 4, which includes a fixing plate 41. A clamping plate 42 is installed on the top of the fixing plate 41. The interior of clamping plate 42 is rotatably connected with fixing bolts 43. A pulley 44 is fixedly connected to the surface of the fixing plate 41. A limit block 45 is fixedly connected to the surface of the fixing plate 41. A movable door 5 is slidably connected to the surface of the mounting frame 2. An electromagnetic lock 51 is fixedly connected to the top of the movable door 5. A fixing rod 52 is rotatably connected to the interior of the electromagnetic lock 51. A fixing ring 53 is fixedly connected to the top and bottom of the fixing rod 52. A pulley 54 is fixedly connected to the bottom of the fixing rod 52. The surface of the movable door 5 is provided with adjustment grooves 36, 37, 48, 59, 50, 51 ... The mounting bracket 2 has a movable groove 55. A fixed door 6 is rotatably connected to the bottom of the mounting bracket 2. A second fixed rod 61 is fixedly connected to the top and bottom of the fixed door 6. An electromagnetic lock 62 is fixedly connected to the top of the fixed door 6. The movable door 5 has an internal locking structure 7, which includes a lever 71. A plug rod 72 is fixedly connected to the top of the lever 71, and a spring 73 is fixedly connected to the bottom of the lever 71. With the locking structure 7, electromagnetic lock 51, and electromagnetic lock 62, the movable door 5 can rotate on the surface of the first fixed rod 52. When the electromagnetic lock is energized, electromagnetic lock 51 locks the movable door 5 to the bottom of the mounting bracket 2, restricting its movement and rotation. Electromagnetic lock 62 locks the fixed door 6 to the bottom of the mounting bracket 2, preventing the movable door 5 and the fixed door 6 from being damaged by external forces. In an emergency requiring the door to open horizontally, the electromagnetic lock 51 is disengaged. Motor 21 drives the synchronous belt 23 to rotate, moving the movable door 5 towards the fixed door 6. Electromagnetic lock 62 is de-energized, releasing the fixed door 6. The toggle plate 71 moves the insert rod 72 down from the circular groove 3, releasing the angle restriction on the movable door 5. This allows the movable door 5 and fixed door 6 to open horizontally at a 90-degree angle. The engagement structure 7, electromagnetic lock 51, and electromagnetic lock 62 work together to reduce the possibility of the automatic door being accidentally opened and to reduce the likelihood of malfunctions caused by accidental opening. An adjustment structure 3 is included. During installation, the adjustment knob 32 is screwed into the sleeve 34 on the adjustment plate 33, and the two ends of the synchronous belt 23 are respectively fitted onto the surfaces of pulley 22 and pulley 35.When the adjusting knob 32 is continuously turned, the adjusting plate 33 moves via the sleeve 34, thereby changing the position of the pulley 35 and thus altering the tension of the timing belt 23. The position of the adjusting knob 32 is fixed by the nut on it to prevent rotation of the adjusting knob 32 when the timing belt 23 pulls the pulley 35. After the adjustment is complete, the position of the adjusting plate 33 is fixed by the cooperation of the fixing bolt 37 and the adjusting groove 36. The tension of the timing belt 23 can be adjusted as needed, making it convenient to use.

[0024] Furthermore, motor 21, electromagnetic lock 51, and electromagnetic lock 62 are all electrically connected to an external power source. The external power source supplies power to and controls motor 21, electromagnetic lock 51, and electromagnetic lock 62. When the electromagnetic locks are energized, electromagnetic lock 51 locks the movable door 5 to the bottom of the mounting bracket 2, restricting the movement and rotation of the movable door 5. Electromagnetic lock 62 locks the fixed door 6 to the bottom of the mounting bracket 2. In an emergency, electromagnetic lock 51 is de-energized, causing the movable door 5 to separate from the mounting bracket 2. The movable door 5 can slide on the ground via pulley 54 and rotate around fixed rod 52. Electromagnetic lock 62 is de-energized, allowing the fixed door 6 to rotate. At the same time, opening limiters are installed on the movable door 5 and the fixed door 6 to limit the opening and closing angle of the door. This is existing technology and will not be described in detail later.

[0025] Furthermore, the two ends of the synchronous belt 23 abut against pulley 22 and pulley 35 respectively. The adjusting plate 33 is mounted on the surface of the mounting plate 31 through the adjusting groove 36 and the fixing bolt 37. The sleeve 34 has a threaded groove inside. One end of the adjusting knob 32 passes through the mounting plate 31 and is rotatably connected in the threaded groove. The surface of the adjusting knob 32 is provided with a nut. During installation, the adjusting knob 32 is screwed into the sleeve 34 on the adjusting plate 33, and the two ends of the synchronous belt 23 are respectively fitted onto the surfaces of pulley 22 and pulley 35. When the adjusting knob 32 is continuously turned, the adjusting plate 33 can be moved through the sleeve 34, thereby changing the position of pulley 35 and thus changing the tension of the synchronous belt 23. The position of the adjusting knob 32 is fixed by the nut on the adjusting knob 32 to prevent the adjusting knob 32 from rotating when the synchronous belt 23 pulls pulley 35.

[0026] Furthermore, the surfaces of the fixing plate 41 and the clamping plate 42 are provided with threaded grooves. The fixing plate 41 and the clamping plate 42 are installed on the surface of the synchronous belt 23 by fixing bolts 43 and threaded grooves. Through the cooperation of fixing bolts 43 and threaded grooves, the fixing plate 41 and the clamping plate 42 are clamped on the surface of the synchronous belt 23. When the motor 21 drives the synchronous belt 23 to rotate through the pulley, the movable door 5 can be moved through the mounting structure 4, thereby realizing the sliding opening and closing of the movable door 5.

[0027] Furthermore, the slide rail 24 is semi-circular, the pulley 44 is rotatably connected to the surface of the slide rail 24, the protrusion 25 is rectangular, and the limiting block 45 is slidably connected to the surface of the protrusion 25. Through the cooperation of the pulley 44 and the slide rail 24, the movement of the movable door 5 is smoother. Through the cooperation of the limiting block 45 and the protrusion 25, the movement of the movable door 5 is limited to prevent it from shaking.

[0028] Furthermore, the surface of the mounting frame 2 is provided with a circular groove 1. The top of the second fixing rod 61 is rotatably connected to the circular groove 1, and the bottom of the second fixing rod 61 is rotatably connected to the ground. The top and bottom of the movable door 5 are provided with circular groove 2. The fixing ring 53 is rotatably connected to the circular groove 2. The first fixing rod 52 passes through the circular groove 2. The second pulley 54 is slidably connected to the ground. The top of the first fixing rod 52 is fixedly connected to the bottom of the fixing plate 41. The fixed door 6 can rotate at the bottom of the mounting frame 2 through the cooperation of the circular groove 1 and the second fixing rod 61. When the motor 21 drives the synchronous belt 23 to rotate through the pulley, the movable door 5 can be moved through the mounting structure 4. The second circular groove 2 and the fixing ring 53, along with the second pulley 54, support the movable door 5 and assist its movement.

[0029] Furthermore, the two ends of the spring 73 are fixedly connected to the bottom of the inner wall of the movable groove 55 and the bottom of the lever 71, respectively. The lever 71 is slidably connected in the movable groove 55. The bottom of the mounting bracket 2 is provided with a circular groove three. The insertion rod 72 passes through the top of the movable groove 55 and is inserted into the inside of the circular groove three. In case of emergency, when it is necessary to open the door horizontally, the electromagnetic lock two 62 is de-energized to release the fixed door 6. The lever 71 is moved to drive the insertion rod 72 to move down from the circular groove three, thereby releasing the angle restriction on the movable door 5. Then, the movable door 5 and the fixed door 6 can be opened horizontally at ninety degrees. Through the cooperation of the locking structure 7, the electromagnetic lock one 51 and the electromagnetic lock two 62, the possibility of the automatic door being opened accidentally is reduced.

[0030] Working principle: During installation, screw the adjusting knob 32 into the sleeve 34 on the adjusting plate 33. Place both ends of the timing belt 23 onto the surfaces of pulley 22 and pulley 35 respectively. Continuously turning the adjusting knob 32 moves the adjusting plate 33 via the sleeve 34, thereby changing the position of pulley 35 and thus altering the tension of the timing belt 23. The nut on the adjusting knob 32 secures its position, preventing rotation when the timing belt 23 pulls pulley 35. After the change is complete, the adjusting plate 33 is fixed in place by the cooperation of the fixing bolt 37 and the adjusting groove 36. The movable door 5 can be accessed via the fixing rod 52. When the surface rotates, and the electromagnetic lock is energized, electromagnetic lock 51 locks the movable door 5 to the bottom of the mounting bracket 2, restricting the movement and rotation of the movable door 5. Electromagnetic lock 62 locks the fixed door 6 to the bottom of the mounting bracket 2, preventing the movable door 5 and the fixed door 6 from opening under external force. In case of emergency, when it is necessary to open the door horizontally, electromagnetic lock 51 is disconnected, and the synchronous belt 23 is driven to rotate by motor 21, thereby moving the movable door 5 towards the fixed door 6. Electromagnetic lock 62 is de-energized, releasing the fixed door 6. The lever 71 is moved to move the insert rod 72 down from the circular groove 3, thereby releasing the angle restriction on the movable door 5, and thus allowing the movable door 5 and the fixed door 6 to open horizontally at a 90-degree angle.
