A gear 220 is meshed between the first rack 120 and the second rack 210. When the second rack 210 is moved toward the side close to the main box body 100 by an external force, the gear 220 drives the first rack 120 to move in the opposite direction, and the locking assembly can lock the final position of the movement of the first rack 120.

[0026] When the gas pressure regulating cabinet of the above structure needs to be repaired, the cabinet door 110 is first opened to allow people to enter the first cavity 101 of the main box body 100, and then the locking assembly is unlocked to allow the sub-box body 200 to move again relative to the main box body 100, and finally the sub-box body 200 is pushed to move toward the side away from the main box body 100, so that the first rack 120 drives the gear 220 to rotate, thereby allowing the first rack 120 to move in the opposite direction, which is conducive to people pushing the sub-box body 200 open inside the main box body 100, so as to achieve the effect of increasing the internal space for people's activities, and thus facilitating people's subsequent repair and treatment. After the inspection and maintenance is completed, people leave the first cavity 101, and then push the sub-box 200 from the outside to move toward the side close to the main box 100, so that the sub-box 200 can be stored relative to the main box 100, which is beneficial to reducing the occupied space of the overall equipment. Finally, the first rack 120 triggers the locking assembly with the cooperation of the gear 220, so that the locking assembly is used to lock the final position of the movement of the first rack 120, which is beneficial to fix the final position of the sub-box 200 and ensure people's usage experience.

[0027] See also Figures 1 to 3 Further, the main box 100 is provided with a first mounting plate 130, the gear 220 is rotatably arranged on the first mounting plate 130, the first mounting plate 130 is provided with an elongated groove 131 parallel to the second rack 210, the first rack 120 is slidably matched with the elongated groove 131, and the locking assembly includes two mutually magnetically attracted first magnets 300 and second magnets 310, one of the first magnets 300 and the second magnets 310 is arranged at one end of the first rack 120, and the other is arranged at the side wall of the elongated groove 131. Specifically, when the sub-box 200 moves toward the side close to the main box 100, the second rack 210 drives the gear 220 to rotate, so that the first rack 120 moves toward the side close to the first magnet 300, so that the first magnet 300 and the second magnet 310 are mutually magnetically attracted, which is conducive to quickly locking the final position of the sub-box 200, and then facilitating the sub-box 200 to be stored in the main box 100. When maintenance is required, people drive the first rack 120 to move toward the side away from the first magnet 300, so that the first magnet 300 and the second magnet 310 are separated from each other, so that the sub-box 200 can be moved relative to the main box 100 again. The magnetic attraction method is simple in structure and unlocking is quick and convenient.

[0028] See also Figures 1 to 3 Furthermore, a waist-shaped hole 132 is provided on the bottom wall of the long groove 131, and the first rack 120 is provided with a screw 121 with one end passing through the waist-shaped hole 132.
