[0039] Specifically, when the waterproof plate 6 hinders the maintenance of the staff, the push-pull rod 5 and the waterproof plate 6 can be driven to move synchronously by pushing and pulling the push-pull block 4. When the push-pull rod 5 moves, the ball 10 will be squeezed and disengaged from the reserved hole of the push-pull rod 5, so that the space occupied by the spring 8 in the cavity 7 can be reduced through the sliding column 9. In this way, the sliding column 9 and the ball 10 can be immersed in the depth of the cavity 7 so as not to hinder the sliding of the push-pull rod 5. When the maintenance is completed, when the push-pull block 4 pushes the push-pull rod 5 and the waterproof plate 6 back to their original position, the ball 10 is aligned with the reserved hole in the push-pull rod 5, so that the force on the ball 10 disappears. At this time, the spring 8 generates a reaction force due to its own restorability, and pushes the ball 10 back to the reserved hole of the push-pull rod 5 through the sliding column 9 to achieve engagement.

[0040] Reference Figure 2 and 4 A groove 13 is provided between the first box body 1 and the second box body 2, a groove 13 is provided between the first box body 1 and the second box body 2, a double-sided adhesive tape 16 is provided between the first sealing layer 14 and the second sealing layer 15, the first sealing layer 14 is filled with asphalt hemp, the second sealing layer 15 is filled with oil felt, a third sealing layer 17 is provided at the bottom of the first sealing layer 14, and the inside of the third sealing layer 17 is filled with polyurethane sealant;

[0041] Specifically, the first sealing layer 14 and the second sealing layer 15 can be pre-bonded together by a double-sided tape 16 to save time for the workers during the filling operation, and the first sealing layer 14 and the second sealing layer 15 bonded together can cooperate to achieve a sealing effect, thereby realizing the first sealing at the groove 13, and then a second sealing is performed by a third sealing layer 17 filled with polyurethane sealant to prevent the first sealing layer 14 and the second sealing layer 15 from insufficiently waterproof and tight, thereby preventing water from penetrating. In addition, the third sealing layer 17 is provided to some extent, which can reduce industrial costs to a certain extent.

[0042] Working principle: When the waterproof plate 6 hinders the maintenance of the staff, the push-pull block 4 can be pushed to drive the push-pull rod 5 and the waterproof plate 6 to move synchronously. When the push-pull rod 5 moves, the ball 10 will be squeezed and thus disengaged from the reserved hole of the push-pull rod 5, so that the slide column 9 and the ball 10 can all enter the cavity 7, allowing the push-pull rod 5 to slide smoothly. When the maintenance is completed, the push-pull rod 5 and the waterproof plate 6 are pushed back to their original positions by the push-pull block 4, and the ball 10 will be aligned with the reserved hole in the push-pull rod 5, so that the force on the ball 10 disappears. At this time, the spring 8 generates a reaction force due to its own restorability, and pushes the ball 10 back through the slide column 9 The push-pull rod 5 is engaged with the reserved hole, and the groove 13 is blocked by the waterproof plate 6 to prevent rainwater from directly eroding it. The interior is made of rubber material, and will not hinder the first box body 1 and the second box body 2 when they expand and contract due to heat and cold. When filling things into the groove 13, the first sealing layer 14 and the second sealing layer 15 can be pre-bonded together by the double-sided tape 16, so that the staff can directly fill it to achieve the first seal, and the third sealing layer 17 filled with polyurethane sealant can be used for secondary sealing, so as to prevent the problem of water penetration caused by insufficient waterproof sealing of the first sealing layer 14 and the second sealing layer 15.
