[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 - Figure 3 This utility model provides an embodiment of an optical signal switching box, including a box 1 for accommodating a converter 3 and a converter 3 for implementing signal conversion. The converter 3 is existing technology, which can start working as soon as it is powered on, and can be implemented by those skilled in the art. Due to the existence of existing technology, this case will not describe it in detail. The rear end of the box 1 is hinged with a box cover 2 for closing the top opening of the box 1. The bottom end of the inner wall of the box 1 is fixedly connected with a support frame 4 for limiting the movement trajectory of the support plate 5. The inner wall of the support frame 4 is inserted with a support plate 5 for supporting the converter 3. The top end of the support plate 5 is equipped with a fixing frame 7 for fixing the converter 3. The converter 3 is placed on the top end of the support plate 5. The converter 3 can be fixed by fixing the fixing frame 7 to the top end of the support plate 5 with bolts. The bottom end of the inner wall of the support frame 4 is provided with a support component 6 for supporting the support frame 4. The left end of the box 1 is provided with an inlet 10 for facilitating the access of external lines to the device.

[0031] Reference Figure 1 - Figure 3The support assembly 6 includes a sliding rail 61 for supporting the movement of the slider 62. The bottom end of the sliding rail 61 is fixedly connected to the bottom end of the inner wall of the support frame 4. The top end of the sliding rail 61 is slidably connected to a slider 62 for pushing a hinge rod 64. The top end of the slider 62 is hinged to a hinge rod 64 for transmitting motion. The top end of the hinge rod 64 is hinged to a push plate 65 for pushing the support plate 5 upward. The push plate 65 slides on the right end of the support frame 4, and the support frame 4 restricts the push plate 65 to move only vertically up and down. The right end of the slider 62 is fixedly connected to a support spring 6 for pushing the slider 62. 3. The right end of the support spring 63 is fixedly connected to the inner wall of the sliding track 61 near the right end. The support spring 63 will push the slider 62 to the left at all times. The bottom of the inner wall of the support frame 4 is fixedly connected to multiple sets of guide rods 8. The support plate 5 slides on the outer wall of the guide rods 8. The guide rods 8 can guide the support plate 5 to move vertically up and down. The top of the guide rods 8 is threaded with a sealing cap 9 to close the opening at the top of the guide rods 8. When it is necessary to completely remove the support plate 5, the sealing cap 9 at the top of the guide rods 8 can be removed by screwing first. Then the support plate 5 can be moved upward to remove it from the inside of the box 1.

[0032] Reference Figure 2 - Figure 4 The rear end of the support frame 4 is slidably connected to a buckle 41 for restricting the movement of the support plate 5. When the support plate 5 is at its lowest point, the buckle 41 can block the top of the support plate 5 so that it cannot move upward. The buckle 41 is L-shaped and has a slope at its rear end. When the slope is squeezed, the buckle 41 will be forced to move forward. The rear end of the buckle 41 is fixedly connected to a positioning block 43 for fixing the support plate 5. The front end of the support plate 5 is provided with a positioning groove 51 for accommodating the positioning block 43. The positioning groove 51 and the positioning block 43 are adapted to each other. When the support plate 5 moves upward until it contacts the bottom end of the sealing cap 9, the positioning groove 51 is just aligned with the positioning block 43. When the positioning block 43 is inserted into the interior of the positioning groove 51, the support plate 5 will be restricted from moving up and down. The front end of the buckle 41 is fixedly connected to a fixing spring 42 for pushing the buckle 41. The front end of the fixing spring 42 is fixedly connected to the inner wall of the support frame 4. The fixing spring 42 will push the buckle 41 backward at all times.

[0033] Working principle: When wiring is required, first open the cover 2, then move the latch 41 forward. At this time, the latch 41 will no longer block the support plate 5. The support spring 63 will push the slider 62 to the left, causing it to move to the left. The slider 62 moving to the left will push the hinge rod 64 to the left and rotate it. The hinge rod 64 moving to the left will push the push plate 65 to move upward. The push plate 65 moving upward will push the support plate 5 to move upward until the top of the support plate 5 contacts the bottom of the sealing cap 9. As the support plate 5 moves upward, it will also move the converter 3 upward and away from the inside of the box 1. Then the latch 41 can be released. The fixing spring 42 will push the latch 41 backward, causing the positioning block 43 to insert into the positioning groove 51 and fix the support plate 5. At this time, wiring can begin.

[0034] After the wiring is completed, the buckle 41 can be moved to move the positioning block 43 out of the positioning groove 51. Then, the support plate 5 can be pressed down to move it back to the lowest position. After that, the buckle 41 can be released. The buckle 41 will move backward under the action of the fixing spring 42 and block the top of the support plate 5. At this time, the support plate 5 will be fixed and cannot be moved. Then, the cover 2 can be rotated to close the box body 1 again.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
