DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example: Reference Figure 1-4 The new type of power cabinet shown in the figure includes a box body 1 and a box door 2. The box body 1 and the box door 2 are hingedly connected. Pulley grooves are provided on the inner walls of both sides of the box body 1. A mounting plate 3 is slidably installed in the two pulley grooves through a sliding assembly. Two square through-holes are provided on the top of the mounting plate 3. A rotating shaft 6 is rotatably installed on the opposite inner walls of the two square through-holes. A rotating rod 7 is fixedly sleeved on the two rotating shafts 6. A third pulley 8 is rotatably installed on the two rotating rods 7. The two third pulleys 8 are respectively slidably installed in the two pulley grooves. The sides of the two rotating rods 7 are opened. A pin hole 9 is provided, and two fixing blocks 13 are installed at the bottom of the mounting plate 3. Circular holes are provided on the sides of the two fixing blocks 13. Pin shafts 14 matching the two pin holes 9 are slidably installed in the two circular holes. A transmission groove is provided at the bottom of the mounting plate 3, and a screw 10 is installed on the relative inner walls of the transmission groove for common rotation. One end of the screw 10 extends out of the transmission groove and is provided with a rotating assembly. A square block 12 is threadedly installed on the screw 10, and the square block 12 is connected to the two pin shafts 14 by a connecting assembly. A buffer assembly is provided at the bottom of the box body 1.

[0022] When the third pulley 8 slides out of the pulley groove, the rotating rod 7 rotates downward again due to the action of gravity on the rotating shaft 6. When the mounting plate 3 slides until the rotating rod 7 and the mounting plate 3 are in a vertical state, the screw 10 is driven to rotate by the rotating assembly, and then the square block 12 is driven to move along the screw 10 in the direction away from the knob 11, and then the two connecting assemblies drive the two pin shafts 14 to move away from each other, so that the two rotating rods 7 are limited by the cooperation of the two pin shafts 14 and the two pin holes 9. At this time, the mounting plate 3 is supported by the two third pulleys 8 and the sliding assembly. This not only allows the mounting plate 3 to be pulled and drawn to a greater extent, but also does not cause damage to the mounting plate 3, making it easier to install and maintain.

[0023] like Figure 3As shown, the sliding assembly includes two first pulleys 4 and two second pulleys 5. Four rectangular holes are opened on the top of the mounting plate 3. The two first pulleys 4 and the two second pulleys 5 are respectively rotatably installed in the four rectangular holes. The two first pulleys 4 and the two second pulleys 5 are respectively slidably installed in the two pulley grooves. The advantage of this arrangement is that through the arrangement of the two first pulleys 4 and the two second pulleys 5, it can make it more convenient and labor-saving when pulling the mounting plate 3.

[0024] like Figure 4 As shown, the rotating assembly includes a knob 11, and the end of the knob 11 is fixedly connected to one end of the screw 10. The advantage of this arrangement is that the screw 10 can be driven to rotate by the knob 11, which is convenient to operate.

[0025] like Figure 4 As shown, the connecting assembly includes a connecting rod 15, one end of the connecting rod 15 is rotatably mounted on the end of the pin shaft 14, and the other end of the connecting rod 15 is rotatably mounted on the side of the square block 12. The advantage of this arrangement is that through the arrangement of the connecting rod 15, the synchronous movement of the pin shaft 14 can be achieved through the movement of the square block 12.

[0026] like Figure 1 As shown, the buffer assembly includes four damping telescopic columns 16, one end of the four damping telescopic columns 16 is fixedly installed on the bottom of the box body 1, and the other end of the four damping telescopic columns 16 is fixedly installed with a shock-absorbing plate 17, and the top of the four shock-absorbing plates 17 is provided with a compression unit. The advantage of this arrangement is that through the arrangement of the damping telescopic columns 16, it can play a better buffering and protection role during the placement and transportation of the power cabinet.

[0027] like Figure 1 As shown, the compression unit includes a compression spring 18, one end of the compression spring 18 is fixedly mounted on the top of the shock-absorbing plate 17, and the other end of the compression spring 18 is fixedly mounted on the bottom of the box body 1. The advantage of this arrangement is that the compression spring 18 can play a second buffering role when the power cabinet is placed, thereby better protecting the internal components.

[0028] like Figure 1 As shown, a rain shield 19 is provided on the top of the box body 1, and through holes are opened on the inner walls on both sides and the top inner wall of the box body 1. Filter plates 20 are fixedly installed in the three through holes. The advantage of this arrangement is that the rain shield 19 can protect the power cabinet when it rains and prevent rainwater from entering the interior and causing damage.

[0029] Working principle: When in use, first pull the mounting plate 3 outward from the box body 1 along the pulley groove. When the third pulley 8 slides out of the pulley groove, the rotating rod 7 rotates downward again due to the action of gravity on the rotating shaft 6. At this time, the mounting plate 3 is supported by the first pulley 4 and the second pulley 5. When the mounting plate 3 continues to slide outward until the rotating rod 7 and the mounting plate 3 are in a vertical state, turn the knob 11, and the knob 11 drives the screw 10 to rotate, thereby driving the square block 12 to move along the screw 10 in the direction away from the knob 11, and then drives the two pin shafts 14 to move away from each other through the two connecting rods 15, so that the two pin shafts 14 cooperate with the two pin holes 9. When the two rotating rods 7 are limited, the mounting plate 3 is supported by the third pulley 8 and the first pulley 4. This not only allows the mounting plate 3 to be pulled and drawn to a greater extent, but also, due to the supporting effect of the two first pulleys 4 and the two third pulleys 8, no damage is caused to the mounting plate 3, making it easier to install and maintain. When use is finished, the mounting plate 3 is pushed in the reverse direction. When the second pulley 5 slides into the pulley groove, the knob 11 is rotated in the reverse direction to drive the two pins 14 to move toward each other, thereby releasing the limit on the two rotating rods 7 and continuing to push the mounting plate 3. Since the side of the rotating rod 7 conflicts with the pulley groove, it will eventually drive the rotating rod 7 to rotate in the reverse direction and reset.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
