DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 , a fast heat dissipation transformer box, comprising a box body 1 and a box top 2, first connecting rods 3 are rotatably installed on the inner side walls of the long sides of the box body 1, two slide rails 4 are arranged on the bottom end of the box top 2, two first connecting rods 3 are arranged on the first sliding shafts 5, the two first sliding shafts 5 are respectively slidably installed in the slide rails 4 at corresponding positions, two second connecting rods 6 are rotatably installed on the bottom end of the box top 2, the two second connecting rods 6 are respectively cross-rotatably connected with the first connecting rods 3 at corresponding positions, and second sliding shafts 7 are arranged on one side of the two second connecting rods 6, sliding grooves 8 are opened on the inner side walls of the long sides of the box body 1, and the two second sliding shafts 7 are respectively slidably installed in the sliding grooves 8 at corresponding positions, electric push rods 9 are arranged on the inner side walls of the two long sides of the box body 1, and the telescopic axes of the two electric push rods 9 are respectively located at one end of the second connecting rod 6 at the corresponding position close to the second sliding shaft 7, and a temperature sensor 10 is arranged on the inner wall of the short side of one side of the box body 1, and the temperature sensor 10 is electrically connected to the two electric push rods 9.

[0022] When the temperature sensor 10 detects that the internal temperature of the box body 1 reaches a critical value, the telescopic shaft of the electric push rod 9 extends out and contacts the second connecting rod 6. Since the second connecting rod 6 is connected to the box top 2, the second connecting rod 6 rotates at the box top 2. At this time, the second sliding shaft 7 slides in the sliding groove 8, and due to the connection between the second connecting rod 6 and the first connecting rod 3, the first connecting rod 3 rotates on the inner wall of the box body 1, and the first sliding shaft 5 slides in the sliding rail 4, so that the box top 2 gradually rises, forming a gap between the top of the box body 1 and the top of the box body 1. At this time, the heat concentrated at the connection between the box body 1 and the box top 2 can be dissipated from the gap to the outside, thereby achieving the purpose of rapid heat dissipation. When the temperature sensor 10 detects that the internal temperature of the box body 1 drops below the critical value, the telescopic shaft of the electric push rod 9 is retracted, so that the second connecting rod 6 loses thrust. Under the action of gravity of the box top 2, the box top 2 gradually descends and merges with the box body 1.

[0023] Specifically, in this embodiment, a first positioning shaft 11 is provided on the inner wall of the box body 1 , one end of the first connecting rod 3 is rotatably mounted on the outer wall of the first positioning shaft 11 , and the first positioning shaft 11 provides a rotation fulcrum for the first connecting rod 3 at a fixed position.

[0024] Specifically, in this embodiment, a second positioning shaft 12 is provided on the central part of the first connecting rod 3, and the central part of the second connecting rod 6 is rotatably mounted on the outer wall of the second positioning shaft 12. The second positioning shaft 12 connects the first connecting rod 3 and the second connecting rod 6, so that the first connecting rod 3 and the second connecting rod 6 can cross-rotate to realize the lifting and lowering movement of the box top 2.

[0025] Specifically, in this embodiment, a connecting member 13 is provided on the bottom end of the box top 2 , and one end of the second connecting rod 6 is rotatably installed in the connecting member 13 . The connecting member 13 provides support for the rotation and lifting movement of the second connecting rod 6 .

[0026] Specifically, in this embodiment, a buffer pad 14 is provided on the bottom end of the box top 2, and the buffer pad 14 is located between the box body 1 and the box top 2. The buffer pad 14 provides a buffering effect for the descent of the box top 2 to prevent collision between the box top 2 and the box body 1.

[0027] Specifically, in this embodiment, a positioning rod 15 is slidably installed in each corner of the top of the box body 1, and several positioning rods 15 are installed on the bottom end of the box top 2. The positioning rods 15 further ensure the stability of the box top 2 in the vertical lifting direction.

[0028] Specifically, in this embodiment, a protective mesh cover 16 is provided on the bottom end of the box top 2, and the protective mesh cover 16 is wrapped around the upper outer wall of the box body 1, so that the gap between the raised box top 2 and the box body 1 can be protected by the protective mesh cover 16, which ensures the heat discharge while preventing dust and snakes, insects, rats and ants from entering the box body 1 and causing damage to the transformer.

[0029] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
