[0030] The inner cavity of the cabinet 1 is provided with a first support plate 4 and a second support plate 5 on the upper and lower sides respectively. The top side of the first support plate 4 and the second support plate 5 are respectively fixedly connected to a second limiting back plate 7 and a first limiting back plate 6. The top side of the second limiting back plate 7 is fixedly connected to a stabilizing block 8. The first support plate 4 and the second support plate 5 can support the installed equipment, and the second limiting back plate 7 and the first limiting back plate 6 can limit the installed equipment without affecting the normal heat dissipation of the equipment. The stabilizing block 8 is adapted to the stabilizing hook groove 3, which can improve the stability of the first support plate 4 after it is pulled out.

[0031] Limiting sliders 13 are symmetrically fixedly connected to the bottom ends of the second support plate 5 and the first support plate 4. Limiting grooves 12 are opened on both sides of the bottom of the inner cavity of the cabinet 1 and on both sides of the top of the partition frame 2. A stabilizing rod 14 is fixedly connected to the middle of the limiting groove 12. Folding support mechanisms are symmetrically arranged on both sides of the bottom of the second support plate 5. By sliding the limiting sliders 13 inside the limiting grooves 12 and cooperating with the stabilizing rods 14, the stability of the horizontal movement of the second support plate 5 and the first support plate 4 can be improved. By pulling the second support plate 5 and the first support plate 4 out of the cabinet 1, it is convenient to pull out the equipment installed in the inner cavity of the cabinet 1 for maintenance and installation, thereby improving the usage effect. The folding support mechanism can support the protruding end of the second support plate 5, thereby improving the stability of the second support plate 5.

[0032] As attached Figure 1 , 2 As shown, ventilation holes are provided on the side wall of the cabinet 1 near the mounting frame 9, and ventilation holes are also provided on the surfaces of the first limiting back plate 6 and the second limiting back plate 7. The ventilation holes improve the heat dissipation effect.

The stabilizing rod 14 passes through the limiting slider 13 and is slidably connected to the limiting slider 13. By allowing the limiting slider 13 to slide inside the limiting groove 12 and by cooperating with the stabilizing rod 14, the stability of the movement of the first support plate 4 and the second support plate 5 can be improved, and the first support plate 4 and the second support plate 5 can be moved more easily, thus improving the performance.

[0034] As attached Figures 1-3 As shown, the stabilizing block 8 corresponds to the stabilizing hook groove 3, and the stabilizing block 8 and the stabilizing hook groove 3 are adapted to each other. The top side of the second support plate 5 and the first support plate 4 are both fixedly connected to the limiting pull plate. By moving the stabilizing block 8 to the middle of the stabilizing hook groove 3, the second limiting back plate 7 can be supported, thereby improving the stability of the movement of the first support plate 4. The limiting pull plate also facilitates the movement of the first support plate 4 and the second support plate 5, improving the usage effect.

[0035] As attached Figures 5-7As shown, the folding support mechanism includes first grooves 15 formed on both sides of the bottom of the second support plate 5. A support rod 16 is rotatably connected to the middle of the first groove 15. A roller 17 is provided on the support rod 16 away from the rotating end. A connecting rod 19 is provided on one side of the connecting plate 20. Second grooves 18 are formed at the bottom of the second support plate 5 and the bottom of the support rod 16. The support rod 16 is placed through the first groove 15 and one end of the support rod 16 extends out to support one end of the second support plate 5, thereby improving the stability of the second support plate 5. The roller 17 ensures that the movement stability of the second support plate 5 is not affected.

[0036] As attached Figures 5-7 As shown, connecting plates 20 are symmetrically arranged at both ends of the connecting rod 19. Both ends of the connecting rod 19 extend into the interior of the connecting plate 20 and are fixedly connected to the limiting block 21. A spring 22 is provided in the middle of the connecting plate 20. By pulling the limiting block 21 through the spring 22, the two connecting plates 20 can be moved to the opposite side. After one end of the support rod 16 moves out of the interior of the first groove 15, the support rod 16 can be supported by the connecting plate 20. After the support rod 16 is unfolded, the rotation angle of the support rod 16 is greater than 90 degrees, which improves the support stability of the first groove 15.

[0037] As attached Figures 5-7 As shown, one end of the connecting plate 20 on one side of the connecting rod 19 is rotatably connected to the inner cavity of the second groove 18 at the bottom of the support rod 16, and one end of the connecting plate 20 on the other side is rotatably connected to the inner cavity of the second groove 18 at the bottom of the second support plate 5. The thickness of the inner cavity of the second groove 18 is the same as the thickness of the connecting plate 20. Through the second groove 18, when the two connecting plates 20 move to opposite sides, the spring 22 is squeezed and the connecting plate 20 is moved to the middle of the second groove 18, which limits the connecting rod 19 and the connecting plate 20 without affecting the stability of the second support plate 5.

[0038] The working principle of this utility model is as follows: When in use, the fan 10 is started and external air is introduced into the cabinet 1 through the dust filter 11 for ventilation and cooling.

[0039] When installing and maintaining equipment, open the cabinet, pull the limit plate to move the second support plate 5 and the first support plate 4 out of the cabinet 1, and place the stabilizing block 8 in the middle of the stabilizing hook groove 3. At this time, the support stability of the first support plate 4 on the equipment can be improved.

[0040] When one end of the second support plate 5 is moved out of the cabinet 1, the end of the support rod 16 near the roller 17 will automatically move out of the first groove 15. The spring 22 pulls the limit block 21, causing the two connecting plates 20 to fit together. At this time, the rotation angle of the support rod 16 is greater than 90 degrees. The support rod 16 and the connecting plate 20 can cooperate to support the moving end of the second support plate 5, improve the stability of the second support plate 5, facilitate the installation, disassembly and maintenance of the equipment, and improve the use effect.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
