The two external teeth 18 are respectively meshed with one side of the gear 10. The ends of the two plug rods 6 close to the gear 10 are sleeved with second springs 17. The two ends of the second spring 17 are respectively connected and fixed to the inner wall of the cabinet door 2 and the rod body of the plug rod 6. The ends of the two plug rods 6 away from the gear 10 extend outward and slide through the inner wall of the cabinet door 2 on the corresponding side. The centers of the extended ends of the two plug rods 6 are aligned, and the ends of the extended ends of the two plug rods 6 are respectively slidably inserted into the shaft sleeves 7 on the corresponding side; In this embodiment, one side of the cabinet door 2 is connected together by the cooperation and limit use of two plug rods 6 and corresponding suspensions 5. When the handle 3 is turned counterclockwise, the two plug rods 6 are driven to move inward at the same time through the cooperation of the gear 10 and the two external teeth 18. One end of the two plug rods 6 are respectively disengaged from the corresponding suspensions 5, and one side of the cabinet door 2 is no longer limited. At this time, pulling the handle 3 outward can rotate the cabinet door 2 from the current side to the other side to open it. Similarly, when the cabinet door 2 needs to be opened from another direction, the plug rod on the other side can be separated from the suspension, and then the handle 3 is pulled outward. The cabinet door 2 can be opened outward from two different directions, which is more convenient to use and is convenient for users to inspect and maintain the electrical components in the cabinet.

[0036] See also Figures 9 to 12 , the two ends of the side panel 20 facing the cabinet body 1 are respectively fixed with a first bracket 23 and a second bracket 24, one end of the first bracket 23 is rotatably connected with a roller 25, and a track 21 is fixed to the rear side of the cabinet body 1, and the track 21 is a similar L-shaped structure, wherein the long end of the L-shaped track 21 includes an inclined upward section and a horizontal section, and a guide groove 22 is opened on the long end of the track 21, and the track 21 and the roller 25 are correspondingly arranged, and the wheel body of the roller 25 is limited and rollingly connected in the guide groove 22, when the side panel 20 stands vertically on one side of the cabinet body 1, the roller 25 is located at the leftmost end of the guide groove 22, and when the side panel 20 is folded upward inside the cabinet body 1, the roller 25 is located at the rightmost end of the guide groove 22; A first connecting rod 27 and a second connecting rod 29 are provided on one side of the side plate 20 corresponding to the track 21. One end of the first connecting rod 27 is connected and fixed to one end of the second connecting rod 29, and the two are inclined at a certain angle. The connecting end of the first connecting rod 27 and the second connecting rod 29 is rotatably connected to the lower end of the track 21 through a pin shaft 28. The end of the second connecting rod 29 away from the first connecting rod 27 is rotatably connected to the second bracket 24. A lever 26 is fixed to the end of the first connecting rod 27 away from the second connecting rod 29, and the front side of the first connecting rod 27 away from the end of the second connecting rod 29 is rotatably connected to the second connecting shaft 32. A positioning seat 30 is fixed below the rear side of the cabinet 1 corresponding to the track 21. The front side of the positioning seat 30 is rotatably connected to the first connecting shaft 31. The first connecting shaft 31 and the second connecting shaft 32 are correspondingly arranged, and a third spring 33 is arranged between the two. The third spring 33 is a spring with hooks at both ends. The two ends of the third spring 33 are respectively hung and fixed on the first connecting shaft 31 and the second connecting shaft 32 through corresponding hooks. When the side panel 20 is completely vertically positioned at one side of the cabinet 1, the roller 25 moves to the leftmost end of the guide groove 22. At this time, the lever 26 is in a vertically upward state and the second connecting shaft 32 is located at the upper left of the first connecting shaft 31. The third spring 33 is driven by the second connecting shaft 32 to tilt and stretch to the upper left. Under the spring tension and the limiting effect of the guide groove 22 on the roller 25, the side panel 20 and the connecting rod structure are locked and positioned at the same time. The side panel 20 is fixed to one side of the cabinet 1 to encapsulate the cabinet 1. When the lever 26 is turned downward again, the side panel 20 is driven to flip inward and finally fold upward at the top of the cabinet 1 through the cooperation of the first connecting rod 27, the second connecting rod 29 and the pin 28. When the side panel 20 is folded, one side of the cabinet 1 is opened, and the operable space inside the cabinet becomes larger, which can facilitate the user to inspect and maintain the electrical components inside the cabinet. When the side panel 20 is in the folded state, the second connecting shaft 32 is located at the upper right of the first connecting shaft 31, and the straight-line distance between the two is relatively shortened at this time. The third spring 33 located between the first connecting shaft 31 and the second connecting shaft 32 will shrink accordingly. At this time, under the tension of the spring and the limiting effect of the guide groove 22 on the roller 25, the side panel 20 and the connecting rod structure are locked and positioned at the same time again. By changing the stretching direction of the spring, the side panel 20 can be locked accordingly when it is in different positions, and the spring only stretches during the turning process. When the side panel 20 is in a fixed position, the spring only maintains the corresponding stretching state and does not move. In this case, the spring is not easy to be fatigued and damaged, and has a longer service life.

[0037] See also Figures 13-14 The ventilation mechanism 19 includes a housing 34 and a ventilation assembly 35 disposed inside the housing 34.

The first crank 36 is fixed to the inside of the housing 34 by a bracket, one end of the third crank 38 is rotatably connected to the front side of one end of the first crank 36, one end of the fourth crank 39 is rotatably connected to the front side of the other end of the third crank 38, one end of the second crank 37 is rotatably connected to the front side of the other end of the fourth crank 39, and the other end of the second crank 37 is rotatably connected to the first crank 36 away from the front side. A connecting seat 41 is fixed to one end of the third crank 38 and one side of the third crank 38. A worm 42 is rotatably connected to the connecting seat 41. The worm 42 is vertically arranged and a fan blade 45 is fixed to the top of the worm 42. A motor 40 is installed at the bottom of the connecting seat 41. One end of the output shaft of the motor 40 is connected and fixed to one end of the worm 42. A worm wheel 43 is fixed to the rear of the fourth crank 39 corresponding to one end of the third crank 38 through a transmission shaft. The worm wheel 43 is meshed and connected with a worm thread 44 on the worm 42. In this embodiment, when the motor 40 drives the worm 42 to rotate, the worm wheel 43 meshing with the worm thread 44 rotates at the same time, and drives the fourth crank 39 to rotate. The two ends of the fourth crank 39 are respectively connected to the second crank 37 and the third crank 38 for rotation, and the other ends of the second crank 37 and the third crank 38 are respectively connected to the first crank 36 for rotation, and the first crank 36 is fixed in the outer shell 34. Therefore, when the fourth crank 39 rotates, it will drive the second crank 37 and the third crank 38 to swing back and forth, and then drive the connecting seat 41 on one side of the third crank 38 to swing back and forth synchronously, so that the worm 42 and the fan blades 45 on the connecting seat 41 swing back and forth synchronously, and the fan blades 45 perform an arc-shaped swinging motion while rotating. The wind blown out by the fan blades 45 forms a fan-shaped wind domain and flows upward from the bottom of the cabinet 1, blowing air evenly to the inside of the cabinet 1, which is conducive to uniform heat dissipation inside the cabinet.
