The movable rod 62 is made of a flexible material. When the movement of the movable rod 62 drives the limit groove 621 to move to the bottom of the limit block 73, one end of the positioning rod 21 fits against the surface of the disc 19, and the positioning rod 21 is located between the two pressure plates 20. Then the limit block 73 moves downward to drive the movable rod 72 and the second rack 16 to move downward, so that the movable cylinder 13 rotates.

During the rotation of the protrusion 23, the pressure plate 20 is squeezed to make the two pressure plates 20 move toward the direction close to the positioning rod 21 until the pressure plate 20 abuts against the positioning rod 21. The abutment limit of the positioning rod 21 of the pressure plate 20 can ensure that the movable rod 62 will not be in a moving state, thereby further ensuring the stability of the cabinet door 3 in the open state.

[0040] The working principle of the present invention is as follows: in the initial state, the cabinet door 3 is in contact with the cabinet body 1, which can prevent external debris from entering the cabinet body 1. When the communication access device needs to be maintained and tested, the cabinet door 3 needs to be opened, and the movable plate 12 needs to be moved laterally along the notch 102. The movement of the movable plate 12 along the notch 102 and the movable groove 613 will drive the movable rod 62 to move laterally along the fixed cylinder 61. When the cabinet door 3 is in a closed state, the bottom of the limit block 73 slides and contacts with the part of the movable rod 62 that does not have the limit groove 621. The spring 11 is in a compressed state. The movement of the movable rod 62 will drive the connecting rod 63 and the first rack 8 to move, thereby driving the first gear 9 and the vertical rod 41 to rotate. The rotation of the vertical rod 41 will drive the rotating plate 4 2 rotates, thereby driving the cabinet door 3 to rotate. The rotation of the cabinet door 3 will drive the other two deflection rods 43 to rotate together. The heights of the deflection rods 43 should be set to different heights, so as to avoid mutual collision between the two deflection rods 43 during the rotation of the cabinet door 3. The number of deflection rods 43 is designed to be two, which can improve the stability of the cabinet door 3 during the rotation process. When the cabinet door 3 is opened, the limit groove 621 part of the movable rod 62 moves to the bottom of the limit block 73. Under the action of the spring 11, the ring 10, the movable rod 72 and the limit block 73 will be driven to move downward until the limit block 73 is engaged with the limit groove 621. At this time, the movable rod 62 cannot continue to move, which can ensure that the cabinet door 3 is in a stable state when it is opened. At the same time, the movable rod 62 The movement of the rod 62 will also drive the movable cylinder 13 and the positioning plate 14 to move. The positioning plate 14 is placed horizontally during the movement, and the square groove 151 of the circular plate 15 is also opened horizontally. Therefore, the positioning plate 14 will pass through the square groove 151 during the movement. When the positioning plate 14 passes through the square groove 151, the limiting groove 621 just moves to the bottom of the limiting block 73. Under the action of the spring 11, the limiting block 73 and the moving rod 72 will move downward. The downward movement of the moving rod 72 will drive the second rack 16 to move downward along the groove 614 and the vertical groove 711. The downward movement of the second rack 16 will cause the second gear 17 to rotate. The rotation of the second gear 17 will drive the movable cylinder 13 to rotate 90 degrees, so that the positioning plate 14 turns from horizontal to vertical. The positioning plate 14 cannot pass back through the square groove 151, and the positioning plate 14 abuts against one side of the circular plate 15, which can further ensure that the movable rod 62 cannot continue to move. In addition, the movement of the movable rod 62 drives the movable cylinder 13, the cross bar 18, the disc 19 and the pressure plate 20 to move synchronously. The pressure plate 20 is made of elastic material. When the movement of the movable rod 62 drives the limiting groove 621 to move below the limiting block 73, one end of the positioning rod 21 fits with the surface of the disc 19, and the positioning rod 21 is located between the two pressure plates 20. Subsequently, the limiting block 73 moves downward to drive the movable rod 72 and the second rack 16 to move downward, causing the movable cylinder 13 to rotate. The rotation of the movable cylinder 13 drives the rotating ring 22 and the protrusion 23 to rotate.During the rotation of the protrusion 23, the pressing plate 20 is pressed to move the two pressing plates 20 toward the direction close to the positioning rod 21 until the pressing plate 20 abuts against the positioning rod 21. The abutment limit of the positioning rod 21 by the pressing plate 20 can ensure that the movable rod 62 will not be in a moving state, further ensuring the stability of the cabinet door 3 in the open state.
