[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-4As shown, an expandable optical cross-box includes a base 1, a C-shaped box 2 is arranged above the base 1, the width of the base 1 is greater than the width of the C-shaped box 2, sealing plates 3 are arranged on both sides of the C-shaped box 2, a first expansion plate 4 is arranged on the back of the C-shaped box 2, the first expansion plate 4 is tightly attached to the back of the C-shaped box 2, the surface of the sealing plate 3 is flush with the surface of the first expansion plate 4, a connecting component is installed between the first expansion plate 4 and the sealing plate 3, and a second expansion plate 5 is arranged on the top and bottom of the C-shaped box 2, and the second expansion plate 5 is installed and connected to the connecting component.

[0020] When it is necessary to increase the internal space of the initial optical cross-box, one side can be widened as selected. At this time, the connection component on the other side needs to be unlocked, and then the sealing plate 3 at this position is pulled to drive the first expansion plate 4 and the two second expansion plates 5 to move, thereby increasing the overall space and providing enough space to install the remaining equipment inside.

[0021] The connecting component includes an X-shaped plug-in plate 6, and the side of the sealing plate 3, the first expansion plate 4 and the back of the C-shaped box 2 are all provided with a half-X-shaped card slot 7, the shape of the card slot 7 is the left half of the X-shape, the card slot 7 of the first expansion plate 4 and the card slot 7 of the sealing plate 3 form an X-shape, and the card slot 7 of the C-shaped box 2 and the sealing plate 3 form an X-shape, the X-shaped plug-in plate 6 is inserted into the inside of the card slot 7, and the X-shaped plug-in plate 6 is inserted into the X-shaped groove formed by the sealing plate 3 and the first expansion plate 4, and the X-shaped groove formed by the sealing plate 3 and the C-shaped box 2 in sequence, so that the stability of the installation can be guaranteed.

[0022] When the space needs to be expanded, first move the X-shaped plug-in plate 6 on one side to the inside of the X-shaped groove formed by the first expansion plate 4 and the sealing plate 3, then move the X-shaped plug-in plate 6 on the other side to make it completely out of the card slot 7, then push the first expansion plate 4 to move to a suitable position, and then insert the X-shaped plug-in plate 6 at this position into the X-shaped groove formed by the sealing plate 3 and the C-shaped box 2 to complete the expansion. The structure is simple and the operation is convenient.

[0023] There are multiple card slots 7 in a rectangular array on the surfaces of the sealing plate 3, the first expansion plate 4 and the C-shaped box 2. There are multiple X-shaped plug-in plates 6 to ensure stable installation. Multiple X-shaped plug-in plates 6 are fixedly connected by a connecting plate 8. Two grooves 9 are provided on the surface of the second expansion plate 5. Both ends of the connecting plate 8 are provided with protrusions 10, which are stuck in the grooves 9. When the X-shaped plug-in plate 6 is away from the inside of the card slot 7, the protrusion 10 will be away from the inside of the groove 9, and when the sealing plate 3 is moved, it will move with the connecting plate 8.

[0024] The top and bottom of the C-shaped box 2 are both provided with guide grooves 11, and the cross-section of the guide groove 11 is set to be trapezoidal. A guide rod 12 is fixedly installed on the surface of the second expansion plate 5, and the shape of the guide rod 12 is adapted to the shape of the inner wall of the guide groove 11. The guide rod 12 is stuck inside the guide groove 11. When the second expansion plate 5 moves, the guide rod 12 moves inside the guide groove 11, which can prevent the second expansion plate 5 from deflecting.

[0025] Two internal thread blocks 13 are respectively installed on the surfaces of the two sealing plates 3, and the internal threads of the internal thread blocks 13 are installed with threaded rods 14. The bottom of the threaded rods 14 rests on the upper surface of the base 1, which can ensure the stable placement of the C-type box 2. When the sealing plate 3 needs to be moved, the threaded rods 14 are rotated to make its bottom away from the surface of the base 1.

[0026] The depth of the slot 7 located in the sealing plate 3 is greater than the depth of the slot 7 in the first expansion plate 4 and the C-shaped box 2 .

[0027] It should be noted that the utility model is an expandable optical cross-box. When in use, first rotate the threaded rod 14 to move its bottom away from the surface of the base 1, move the X-shaped plug-in plate 6 on one side to the inside of the X-shaped groove composed of the first expansion plate 4 and the sealing plate 3, and then move the X-shaped plug-in plate 6 on the other side to make it completely out of the interior of the card slot 7. When the X-shaped plug-in plate 6 is away from the interior of the card slot 7, the protrusion 10 will be away from the interior of the groove 9, and when the sealing plate 3 is moved, it will move with the connecting plate 8, and then push the first expansion plate 4 to move to a suitable position, and then insert the X-shaped plug-in plate 6 at this position into the interior of the X-shaped groove composed of the sealing plate 3 and the C-shaped box body 2, thereby increasing the overall space and providing sufficient space to install the remaining equipment inside it, and finally reverse the threaded rod 14 so that its bottom is against the surface of the base 1.
