The sealing box 100 of the embodiment is fixedly connected to one side of the door body facing the box body, as shown in fig. 1 and 2, the sealing box 100 comprises a cabinet body 10 and a cover body 20, the cabinet body 10 is connected to the door body, the cabinet body 10 comprises a cabinet body 11 enclosing an opening 111 and a guide rail groove 12 arranged at the opening 111, and the cabinet body 11 encloses a storage space 110; the cover 20 is provided with two fans, the two fans of cover 20 are arranged in parallel, the two fans of cover 20 comprise sliding parts 22 arranged in the guide rail grooves 12, and the sliding parts 22 are used for sliding along the guide rail grooves 12.

When the door body is in a closed state, the cover body 20 seals the storage space 110, and the two cover bodies 20 are propped against each other;

When the door is in an open state, the cover 20 is exposed outward, and when the cover 20 is required to open the storage space 110, at least one of the two covers 20 moves in a direction away from the other cover 20.

Further, in order to optimize the movement of the cover 20, the guide rail groove 12 includes an upper guide rail groove 122 and a lower guide rail groove 121 which are disposed opposite to each other up and down, and the sliding portion 22 includes an upper sliding portion 222 disposed in the upper guide rail groove 122 and a lower sliding portion 221 disposed in the lower guide rail groove 121, so that the smooth movement of the cover 20 can be ensured. This design helps to reduce friction of the sliding portion 22 and improves the operation efficiency of the cover 20. The surface of the rail groove 12 may be made of a smooth material such as an aluminum alloy with a low friction coefficient, polytetrafluoroethylene, or the like to ensure smoothness of sliding.

The cabinet 10 further includes a closing stopper 13 provided at a middle position of the upper rail groove 122, so that the firmness of the cover 20 in the closed state can be ensured, and as shown in fig. 2, 5 and 7, the closing stopper 13 includes stopper grooves 131 of the cover 20 facing both sides, respectively, and the sliding portion 22 includes stopper pieces insertable into the stopper grooves 131. The design of the closing stop 13 ensures that when the cover 20 is closed, the stop block and the stop groove 131 lock with each other, limiting the movement of the sliding part 22, forming a reliable stop mechanism, thus maintaining a stable state of the cover 20.

Further, the sliding portion 22 includes a sliding body 2211, and a plurality of sliding wheels 2212 rotatably connected to the sliding body 2211, as shown in fig. 4, 5 and 7, the sliding wheels 2212 are installed in the guide groove 12, and at least one sliding wheel 2212 and the stop block are configured as the same structure. In this embodiment, at least one slide wheel 2212 is configured identically to the stop block, and is configured as a slide wheel 2212 to ensure that it is securely retained within the stop groove 131 during sliding. The slide body 2211 may be connected to a frame 23 below. To enhance the durability of the cover 20, the slide wheel 2212 may be made of a high strength, abrasion resistant material, such as nylon or polyamide. The surface of the slide wheel 2212 may be provided with an anti-slip coating to ensure smoothness during movement.

The closing stop 13 comprises a socket 132, as shown in fig. 7, the distance of the socket 132 being smaller than the diameter of the slide wheel 2212 at the height of the socket 132, the socket 132 restraining the slide wheel 2212 with a tendency for the slide wheel 2212 to remain in the stop groove 131.

Further, each of the sliding parts 22 includes at least two sliding wheels 2212, and the cover 20 is restrained from moving only in the extending direction of the guide rail groove 12 by sliding of at least two sliding wheels 2212 of the upper sliding part 222 and at least two sliding wheels 2212 of the lower sliding part 221 within the guide rail groove 12, as shown in fig. 2, 4 and 5. The number and arrangement of the pulleys 2212 can meet the requirements of the constraint cover 20, and in addition, can better accommodate uneven loads that may be present.

In the present embodiment, by sliding the plurality of slide wheels 2212 of the upper slide portion 222 and the lower slide portion 221 within the guide rail groove 12, the movement of the cover 20 only in the extending direction of the guide rail groove 12 can be restrained better, ensuring smooth opening and closing of the cover 20. The restriction of the upper and lower rail grooves 122 and 121 by four slide wheels 2212 for each cover 20 is completed, so that the position and movement of the cover 20 are limited, and the running stability of the cover 20 and the durability of the sealing box 100 are improved.

In addition, a lubrication system can be added in the guide rail groove 12 to reduce friction of the sliding part 22 and further improve the movement efficiency of the cover 20.

The cabinet 10 further includes a guide wheel 15, as shown in fig. 3 and 5, the guide wheel 15 is disposed between the cabinet body 11 and the cover 20, and when the cover 20 moves between the open storage space 110 and the closed storage space 110, the cover 20 rolls against the guide wheel 15. The function of these guide wheels 15 is to ensure that the cover 20 rolls smoothly against each other when opened and closed, avoiding unnecessary resistance caused by friction. The guide wheel 15 is made of a lightweight but strong material such as a high strength plastic or aluminum alloy in consideration of the force and pressure it receives during the movement of the cover 20. The design of the guide wheel 15 needs to take into account the forces and pressures experienced during the movement of the cover 20 to ensure durability and reliability of the guide wheel 15.

The cabinet 10 further includes an opening stopper 14 provided at a distal end portion of the guide rail groove 12, and when the cover 20 is opened to the maximum position, the sliding portion 22 abuts against the opening stopper 14 as shown in fig. 3 and 5.
