DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0019] Referring to Figs. 1-3 A drawer type photovoltaic direct current power distribution cabinet includes a cabinet body 1, three drawer bodies 2 are arranged on the cabinet body 1, handles 16 are arranged on the three drawer bodies 2, two mounting slots 7 are arranged on the side wall of the cabinet body 1, the two mounting slots 7 are located below the upper two drawer bodies 2 respectively, and support mechanisms are arranged on the two mounting slots 7.

[0020] The support mechanism includes a threaded rod 15 rotatably connected to the inner wall of one side of the mounting groove 7. A movable block 14 threadedly connected to the outer side of the threaded rod 15 is provided. Two first fixing blocks 3 are fixedly installed on one side of the outer wall of the cabinet 1. A first rotating shaft 8 is rotatably connected between the two first fixing blocks 3. A support plate 4 is fixedly installed on the outer wall of the first rotating shaft 8. Two second fixing blocks 9 are fixedly installed on the side wall of the support plate 4 near the mounting groove 7. A second rotating shaft 10 is rotatably connected between the two second fixing blocks 9. The movable block 14 is located near the support plate 4. A third fixing block 13 is fixedly installed on one side wall of the support plate 4. A third rotating shaft 12 is rotatably connected between the two third fixing blocks 13. One end of a connecting rod 11 is fixedly installed on the outer side wall of the second rotating shaft 10. The other end of the connecting rod 11 is fixedly installed on the outer side wall of the third rotating shaft 12. Anti-slip protrusions 5 are evenly distributed on the side wall of the support plate 4 away from the mounting groove 7. One end of the threaded rod 15 passes through the inner wall of one end of the mounting groove 7 and a knob 6 located outside the mounting groove 7 is fixedly installed. The moving block 14 is slidably connected to the inner bottom of the mounting groove 7.

[0021] In use, this utility model allows electrical components inside the cabinet 1 to be pulled out for maintenance by setting the drawer body 2. When it is necessary to pull out the upper drawer body 2 to inspect the internal electrical components, the threaded rod 15 is rotated by turning the knob 6. When the threaded rod 15 rotates, the moving block 14 will not rotate because it is threadedly connected to the threaded rod 15 and slidably connected to the inner bottom of the mounting groove 7. This allows the moving block 14 to move closer to or away from the support plate 4. When the moving block 14 moves closer to the support plate 4, its connecting rod 11 will rotate. The rotation of the connecting rod 11 causes the support plate 4 to rotate around the first pivot 8, thereby allowing the support plate 4 to rotate to a horizontal state to provide auxiliary support for the pulled-out drawer body 2. This avoids the problem that the drawer body 2 and the internal electrical components are too heavy and the staff may not be able to hold it steadily, causing the drawer body 2 to fall and be damaged. The anti-slip protrusions 5 on the support plate 4 can enhance the anti-slip effect and improve the stability of the auxiliary support.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
