[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a dustproof distribution box suitable for outdoor environments, comprising a box body 1 and a box door 2. A sealing frame 14 is installed on the inner side of the box door 2, which is inserted into the box body 1 and contacts the inner side of the box body 1. The inner side of the box door 2 abuts against the opening end face of the box body 1. Pressing mechanisms that drive the box door 2 to move toward the box body 1 are installed on both sides of the box body 1. A connecting groove 10 is provided at one end of the box body 1, and a connecting plate 3 is installed at one end of the box door 2. The connecting plate 3 extends to the outside of the connecting groove 10, and a positioning block 9 is installed on the inner side of the connecting plate 3. A connecting block 8 is installed at the end of the connecting plate 3 away from the box door 2 through a hinge. Both the positioning block 9 and the connecting block 8 are slidably disposed in the connecting groove 10.

[0020] In this embodiment, the connecting groove 10 has two protruding limiting parts 11 on both sides of the opening facing the door 2. The connecting block 8, the positioning block 9 and the connecting groove 10 are all arranged in a trapezoidal structure. The positioning block 9 has parallel surfaces 12 on both sides that pass through the limiting parts 11.

[0021] In this embodiment, the clamping mechanism includes a first fixing block 5, a second fixing block 4, a screw 7, a sealed bearing 13, and a handwheel 6. The first fixing block 5 is installed on the side of the door 2, and the second fixing block 4 is installed on the side of the box body 1, and is arranged opposite to the first fixing block 5. The second fixing block 4 is provided with screw holes. The sealed bearing 13 is embedded in the center of the first fixing block 5. The screw 7 is installed in the inner ring of the sealed bearing 13. One end of the screw 7 is threaded into the screw hole, and the other end is fixedly connected to the handwheel 6.

[0022] In this embodiment, the outer side of the sealing frame 14 is provided with a plurality of frame-shaped grooves, and a sealing ring 15 is installed inside each groove. The outer side of the sealing ring 15 is in contact with the inner side of the housing 1. After the sealing ring is pulled outward, it can be removed from the groove, which facilitates the replacement of the sealing ring.

[0023] In this embodiment, the inner side of the connecting plate 3 is in contact with the outer wall of the box 1, so that the connecting plate can move stably along the outer wall of the box.

[0024] During use, the door can move horizontally towards the box body, allowing the sealing frame to enter the box body. The inner side of the door then contacts the opening end of the box body. When in contact, the handwheel can be rotated, which drives the screw, allowing the screw to be threaded into the screw hole. The screw presses the door tightly against the box body, ensuring a tight seal between the box body and the door, greatly reducing the probability of gaps. The sealing frame increases the contact area between the box body and the door, and together with the sealing ring, it can better intercept external impurities, preventing impurities from entering the interior of the box body.

[0025] When parts need to be disassembled or repaired, the screw can be unscrewed from the screw hole and the door can be moved outward along the connecting groove. The movement of the door moves the sealing frame. After the sealing frame is moved out of the box, the connecting plate continues to move until the positioning block moves out of the connecting groove along the channel between the limiting parts. After the positioning block is no longer limiting, the connecting plate can rotate downward around the hinge, so that the opening of the box can be fully opened, facilitating the operation inside.

[0026] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
