As a detailed explanation: a short installation groove for matching with the second rotating rod 811 is opened on one side of the right movable side panel 705 close to the inside of the communication cabinet body 2.

[0024] The present invention also discloses a method for using a communication cabinet that is easy to maintain, which specifically includes the following steps: S1, routine inspection and maintenance: by opening the auxiliary cabinet door 17, the interior of the communication cabinet body 2 is exposed, and then routine inspection and maintenance are carried out; S2, maintenance space expansion: start the servo motor 704 in the space expansion mechanism 7, so that the servo motor 704 synchronously drives the front cabinet door 5 and the rear cabinet door 6 to be synchronously expanded forward and backward. During the expansion of the front cabinet door 5 and the rear cabinet door 6, the two movable side panels 705 on the same side are synchronously driven to move and expand in the opposite direction on the side of the communication cabinet body 2; The specific steps are: Figure 1 , Figure 2 , Figure 4 , Figure 5 and Fig.11As shown, the servo motor 704 is started, prompting the servo motor 704 to drive the front corner rod 4 to rotate forward ninety degrees, and the front corner rod 4 drives the front cabinet door 5 to unfold forward ninety degrees. The rotation of the front corner rod 4 synchronously drives the front first gear 701 to rotate, and the front first gear 701 engages with the left tooth limit block 703, prompting the frame 702 to move forward. The forward movement of the frame 702 will drive the right tooth limit block 703 to engage with the rear first gear 701, prompting the rear corner rod 4 to drive the rear cabinet door 6 to rotate backward ninety degrees synchronously to unfold; like Figure 4 , Figure 7 , Fig.11 and Fig.12 As shown, during the rotation and expansion of the rear cabinet door 6, the rear cabinet door 6 synchronously pulls the second mounting frame 713 and the second connecting rod 714 to move. During the movement of the second connecting rod 714, the first mounting frame 712 and the slide groove plate 711 are lateral slidingly matched, and the slide groove plate 711 and the V-shaped groove frame 710 are vertically slidably matched to provide a compensation distance for the change of the rotation angle during the movement of the second connecting rod 714, until the rear cabinet door 6 is rotated backward to ninety degrees, wherein the second connecting rod 714 moves with the rear cabinet door 6, and through the first mounting frame 712, the second connecting rod 714 is vertically matched to the V-shaped groove frame 710. When the V-groove frame 710 is pulled backward by the mounting frame 712 and the slide plate 711, the V-groove frame 710 will simultaneously push the guide roller sleeve 709 laterally through the gradually changing wide-distance inclined groove, causing the guide roller sleeve 709 to drive the L-shaped curved rod 708 to move laterally. When the L-shaped curved rod 708 moves laterally, the first connecting rod 707 that is pushed will change its angle, causing the first connecting rod 707 to push the movable side panel 705 to slide and unfold on the side of the communication cabinet body 2, thereby exposing the side operating space of the communication cabinet body 2.

[0025] S3, auxiliary expansion of the tool table: while the space expansion mechanism 7 synchronously drives the front cabinet door 5, the rear cabinet door 6 and the movable side panel 705 to expand, the space expansion mechanism 7 synchronously drives the multi-surface placement mechanism 8 to carry out linkage, so that the long frame 802 and the short frame 812 in the multi-surface placement mechanism 8 are synchronously expanded vertically in different directions; The specific steps are: Figure 2 , Figure 6 , Figure 7 , Fig. 9 , Fig.10 and Fig.12As shown, when the movable side plate 705 is pushed by the first connecting rod 707 to slide on the side of the communication cabinet body 2, the movable side plate 705 synchronously drives the Z-shaped rod 808 and the ball 809 to move. When the sliding stroke of the movable side plate 705 ends, the ball 809 slides to the inclined surface of the inclined pad 810 at the same time, prompting the ball 809 to drive the Z-shaped rod 808 and the storage slide column 805 to rise. The rise of the storage slide column 805 synchronously drives the first tooth plate 807 to rise, prompting the first tooth plate 807 to mesh with the second gear 803. After the first tooth plate 807 and the second gear 803 are meshed, the second gear 803 will drive the placement long frame 802 to flip and unfold by 90 degrees through the first rotating rod 801, which provides convenience for the subsequent placement of maintenance tools on both sides of the communication cabinet body 2. When the above-mentioned storage slide column 805 moves, the right storage slide column 805 will also synchronously drive the second tooth plate 814 to rise, prompting the second tooth plate 814 to engage with the third gear 813. After the second tooth plate 814 and the third gear 813 are engaged, the third gear 813 will drive the short placement frame 812 to flip ninety degrees through the second rotating rod 811, thereby providing convenience for the placement of maintenance tools on the front and rear sides of the communication cabinet body 2.

A method for using a communication cabinet that is easy to maintain, characterized in that: The specific steps include: S1, routine inspection and maintenance: opening the auxiliary cabinet door (17) to expose the interior of the communication cabinet body (2) for routine inspection and maintenance; S2, maintenance space expansion: start the servo motor (704) in the space expansion mechanism (7), so that the servo motor (704) synchronously drives the front cabinet door (5) and the rear cabinet door (6) to be synchronously expanded forward and backward, and during the expansion of the front cabinet door (5) and the rear cabinet door (6), the two movable side panels (705) on the same side are synchronously driven to move and expand in the opposite direction on the side of the communication cabinet body (2); S3, auxiliary unfolding of the tool table: while the space unfolding mechanism (7) synchronously drives the front cabinet door (5), the rear cabinet door (6) and the movable side panel (705) to unfold, the space unfolding mechanism (7) synchronously drives the multi-faceted placement mechanism (8) to perform linkage, so that the long frame (802) and the short frame (812) in the multi-faceted placement mechanism (8) are synchronously unfolded vertically in different directions.
