The axial slide rails 51 are perpendicular to the surface of the wall substrate 2. The first rollers 52 slide along the axial slide rails 51, so that the dark door frame 4 can slide in the fixed frame 1, thereby pushing the door panel fixing plate 7 and the curved door panel 10 hidden in the curved decorative panel away from the wall substrate 2, so that there is no interference between the opening and closing of the curved door panel 10 and the curved decorative panel 9, thereby ensuring the beauty of the decorative effect.

[0047] The second sliding mechanism 8 includes a radial slide rail 81 and two second rollers 82. The radial slide rail 81 is fixedly mounted on the dark door frame 4. The second rollers 82 are fixedly mounted on the door panel fixing plate 7. The second rollers 82 are slidably arranged in the radial slide rail 81. The radial slide rail 81 is arranged perpendicular to the axial slide rail 51. The second rollers 82 slide along the radial slide rail 81, that is, the door panel fixing plate 7 can be opened and closed on the dark door frame 4.

[0051] The axis of the spring 63 and the axial slide rail 51 are parallel to each other;

[0052] The arc surface 13 on the curved door panel 10 overlaps with the arc surface 13 on the curved decorative panel 9, which is beneficial to the beautiful decorative effect.

[0053] Working principle: First, when the door needs to be opened, the curved door panel 10 is pushed inward, the spring 63 is compressed, and after being released, the spring 63 rebounds and elastically pushes the hidden door frame 4 to slide in the fixed frame 1, and the first roller 52 slides in the axial slide rail 51. When the hidden door frame 4 slides a certain distance, the first magnetic block 61 and the second magnetic block 62 are disengaged, and the first stop plate 11 stops the first roller 52. At this time, the curved door panel 10 hidden in the curved decorative panel 9 and the door panel fixing plate 7 protrude from the curved decorative panel 9. Secondly, the curved door panel 10 is pushed, and the door panel fixing plate 7 protrudes from the curved decorative panel 9. Plate 7 slides, the second roller 82 slides along the radial slide rail 81, and the second stop plate 12 stops the second roller 82, completing the opening of the manhole door, and entering the pipe well from the dark door frame 4 to perform operations, then, push the curved door panel 10 to reset, push the curved door panel 10 inward, and the dark door frame 4 slides along the fixed frame 1. When pushing, pay attention to the edge of the curved door panel 10 and the edge of the curved decorative panel 9 to match, finally, the first magnetic block 61 and the second magnetic block 62 are magnetically adsorbed, the surface of the curved door panel 10 and the surface of the curved decorative panel 9 coincide, and the closing of the manhole door is completed.
