Specific embodiments

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0021] Please refer to Figures 1 - 4, a description of a control cabinet assembly provided by an embodiment of the present utility model will be given now. A control cabinet assembly includes a control cabinet main body 1. The front end of the control cabinet main body 1 is rotatably connected to a closing door 2 through a hinge. Two fixing seats 8 distributed up and down are fixedly connected to the rear end of the closing door 2. Link rods 9 are rotatably connected to one ends of the two fixing seats 8 away from each other. Guide rails 7 are fixedly connected to the inner wall of the control cabinet main body 1. An installation frame 12 is slidably connected to the outer surfaces of the two guide rails 7. Sliding grooves 11 are formed in the upper and lower end surfaces of the installation frame 12. Sliding seats 10 are slidably connected to the interiors of the two sliding grooves 11. The two link rods 9 are respectively rotatably connected to the two sliding seats 10. Circular holes 16 are formed in the rear end surface of the control cabinet main body 1. Two mounting plates 13 are connected to the rear end of the control cabinet main body 1 through a plurality of connecting members. The two mounting plates 13 are respectively located directly behind the two circular holes 16. Heat dissipation fans 15 are fixedly connected to the front ends of the two mounting plates 13. The two heat dissipation fans 15 are respectively located in the two circular holes 16 and are simultaneously located behind the installation frame 12. The connecting members include nuts and threaded rods 14. A plurality of threaded rods 14 are fixedly connected to the rear end of the control cabinet main body 1. Through holes for the threaded rods 14 to pass through are formed in the rear end surface of the mounting plate 13. Nuts are threadedly connected to the circumferential surface of the threaded rods 14. The nuts are located behind the mounting plate 13. During operation, when the closing door 2 is opened and rotates around the hinge, the fixing seat 8 will be driven to rotate. With the cooperation of the link rod 9 and the sliding seat 10, the installation frame 12 is pulled to move forward along the guide rail 7. At the same time, the sliding seat 10 will also move along the sliding groove 11. Until the closing door 2 is completely opened, the installation frame 12 can move to the exact front end inside the control cabinet main body 1. At this time, the electrical components installed at the front end of the control cabinet main body 1 will move to the front end of the control cabinet main body 1. In addition, after using tools to block the closing door 2, the electrical components on the installation frame 12 can be repaired. (In the present utility model, the control cabinet main body 1, the installation frame 12, the link rod 9, the sliding groove 11, the sliding seat 10 and the fixing seat 8 constitute the control cabinet assembly).

[0022] A control cabinet assembly provided by the present utility model, compared with the prior art, can automatically drive the installation frame 12 to move forward along the guide rail 7 while opening the closing door 2 under the mutual cooperation of the fixing seat 8, the link rod 9, the sliding groove 11 and the sliding seat 10. When the closing door 2 is completely opened, the installation frame 12 can move to the exact front end inside the control cabinet main body 1, thereby facilitating the staff to repair the electrical components on the installation frame 12.

[0023] In another embodiment of the present utility model, please refer to Figure 3, a plurality of ventilation holes 18 are formed in the front end face of the mounting frame 12; a plurality of heat dissipation holes 6 are formed in the upper end face of the control cabinet main body 1. During operation, the wind generated by the heat dissipation fan 15 can enter the front end of the mounting frame 12 through the ventilation holes 18 or directly blow to the rear end face of the electrical components through the ventilation holes 18, so that the heat of the electrical components is dissipated outward through the heat dissipation holes 6. Thus, not only can the rear end of the electrical components be directly ventilated and cooled, but also the air circulation inside the control cabinet main body 1 can be accelerated, thereby reducing the probability of damage to the electrical components due to overheating.

[0024] In another embodiment of the present invention, please refer to Figures 1 to 3 , a support frame 3 is fixedly connected to the bottom end of the control cabinet main body 1. During operation, the support frame 3 can stably support the control cabinet main body 1, preventing the control cabinet main body 1 from directly contacting the ground and preventing dust or water on the ground from affecting the control cabinet main body 1.

[0025] In another embodiment of the present invention, refer to Figure 3 , two protective covers 17 are fixedly connected to the inner wall of the control cabinet main body 1. The two protective covers 17 are located between the circular holes 16 and the mounting frame 12. The two protective covers 17 are respectively located directly in front of the two circular holes 16, and the two heat dissipation fans 15 respectively extend into the two protective covers 17. Ventilation holes are formed in the front end faces of the two protective covers 17. During operation, the protective covers 17 are used to protect and block the heat dissipation fans 15. When the wires of the electrical components on the mounting frame 12 run to the rear side of the mounting frame 12 through the ventilation holes 18, the wires will not directly contact the heat dissipation fans 15, thereby preventing damage to the wires and electrical components.

[0026] In another embodiment of the present invention, please refer to Figures 1 to 3 , a support seat 4 is fixedly connected to the upper end of the control cabinet main body 1, and a top plate 5 is fixedly connected to the upper end of the support seat 4. The top plate 5 is located directly above the heat dissipation holes 6. During operation, the top plate 5 is used to protect the heat dissipation holes 6, preventing falling dust and impurities from entering the control cabinet main body 1 through the heat dissipation holes 6.

[0027] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
