[0030] 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.

[0031] Reference Figure 1-Figure 3 , the utility model provides an embodiment: a control box for a generator, including a control box 1, wherein electronic components are installed in the control box 1, which is usually composed of a microprocessor or a dedicated integrated circuit. It is responsible for receiving signals from various sensors, performing data processing and analysis, and issuing control instructions. This is the prior art and will not be described in detail here. The outer wall of the control box 1 is in contact with a control cover 2. The control cover 2 will have some logos and indicator light windows so that the operator can understand the operating status of the generator. This is the prior art and will not be described in detail here. The outer wall of the control cover 2 is fixedly connected to a fixed block 3, which mainly supports and connects the entire connecting rod 4 and the sunshade 8. The inner wall of the fixed block 3 passes through and is rotatably connected to the connecting rod 4. The inner wall of the connecting rod 4 is provided with a positioning mechanism. The left end of the connecting rod 4 is fixedly connected to the sunshade 8. The sunshade 8 is made of opaque material and can prevent light from directly penetrating the sunshade 8. The outer wall of the control cover 2 is provided with a display screen 9, through which the operation of the generator can be observed. The outer wall of the control cover 2 is provided with a connecting component.

[0032] Reference Figure 3-Figure 5 The connecting assembly includes an insert frame 10, which is fixedly connected to the outer wall of the control cover 2. The side wall of the insert frame 10 is plugged with a cross block 11, as shown in FIG. Figure 5As shown, the left end of the cross block 11 has raised portions corresponding to the vertical opening of the cross slot, and the right end of the cross block 11 corresponds to the horizontal opening of the cross slot. In the initial state, the cross block 11 is completely inserted into the cross slot. Figure 4 As shown, a cross slot is provided on the insertion frame 10, and a pressing plate 13 is fixedly connected to the right end of the cross block 11. The pressing plate 13 can be pressed to move the pressing plate 13 with the cross block 11. The left end of the pressing plate 13 is elastically connected to the control box 1 through a positioning spring 12. The left end of the pressing plate 13 is fixedly connected to one end of the positioning spring 12. When the pressing plate 13 moves to the right, the positioning spring 12 is compressed. When resetting, the elastic force of the positioning spring 12 is used to reset the pressing plate 13. The other end of the positioning spring 12 is fixedly connected to the side wall of the control box 1. The cross block 11 passes through and is slidably connected to the inner wall of the control box 1. A notch corresponding to the cross block 11 is provided on the control box 1, which can meet the needs of the cross block 11 to move horizontally along the notch, and the insertion frame 10 is plugged into the inner wall of the control box 1.

[0033] Reference Figure 1-Figure 3 The positioning mechanism includes a moving plate 6, which passes through and is slidably connected to the inner wall of the connecting rod 4. A notch is provided on the connecting rod 4, which allows the moving plate 6 to move vertically along the connecting rod 4. The top of the moving plate 6 is fixedly connected to the limiting block 7, which is inclined. When the inclined surface is squeezed, the limiting block 7 slides on the inner wall of the connecting rod 4. The bottom end of the moving plate 6 is elastically connected to the connecting rod 4 through a return spring 5. The bottom end of the moving plate 6 is fixedly connected to one end of the return spring 5. When the connecting rod 4 moves downward, the return spring 5 is compressed. When it is reset, The elastic force of the return spring 5 is used to restore the movable plate 6. The other end of the return spring 5 is fixedly connected to the inner wall of the top end of the connecting rod 4. The limit block 7 passes through and is slidably connected to the inner wall of the connecting rod 4. The limit block 7 is plugged into the inner wall of the fixed block 3. The fixed block 3 is provided with three groups of notches corresponding to the limit blocks 7, which can meet the one-way limitation of the limit blocks 7 and the shading plate 8 by their insertion. The outer wall of the shading plate 8 contacts the outer wall of the control cover 2. The button part of the control cover 2 can be protected by the shading plate 8 to avoid accidental touch affecting the operation of the generator.

[0034] Working principle: First, when you need to observe the display screen 9, you only need to flip the shading plate 8 clockwise from the bottom end of the shading plate 8, so that the shading plate 8 and the connecting rod 4 rotate along the inner wall of the fixed block 3 as the center, which will make the inner wall notch of the fixed block 3 squeeze the inclined surface of the limit block 7, so that the limit block 7 moves downward with the movable plate 6 and compresses the reset spring 5, so that the limit block 7 is retracted into the notch of the connecting rod 4. When the limit block 7 and the inner wall notch of the next fixed block 3 coincide with each other, the reverse elastic force of the reset spring 5 is used to bring the movable plate 6 and the limit block 7 back to their original position, so that the limit block 7 is plugged into the inner wall notch of the fixed block 3, so that the shading The plate 8 is in a horizontal position, and the shading plate 8 is used to block the light to prevent the staff from seeing the values on the display screen 9 clearly. When it is necessary to prevent the shading plate 8 from blocking the light and observe the display screen 9, it is only necessary to continue to flip the shading plate 8 clockwise to flip the shading plate 8 to the vertical position. After the observation is finished, the movable plate 6 can be pressed to move the movable plate 6 with the limit block 7 downward and compress the return spring 5 to separate the limit block 7 and the inner wall notch of the fixed block 3, and then the shading plate 8 is rotated counterclockwise to rotate along the inner wall of the fixed block 3 as the center. During the rotation, the hand continues to press the movable plate 6 to allow the shading plate 8 to return to the vertical position. Figure 1 In the initial state shown, the movable plate 6 is finally released and the reverse elastic force of the reset spring 5 is used to bring the movable plate 6 and the limit block 7 back upward, so that the limit block 7 can be plugged into the inner wall groove of the fixed block 3.

[0035] When it is necessary to disassemble the control cover 2 and maintain the electronic components in the control box 1, it is only necessary to press the pressing plate 13 to move the cross block 11 to the left and compress the positioning spring 12, so that the protruding part of the left end of the cross block 11 leaves the vertical opening of the cross slot of the plug-in frame 10. At this time, the right end of the cross block 11 and the horizontal opening of the cross slot of the plug-in frame 10 are still in the overlapped state. At this time, move the control cover 2 and the plug-in frame 10 outward to separate the cross slot of the plug-in frame 10 from the right end of the cross block 11, and the plug-in frame 10 from the inner wall of the control box 1. After the maintenance is completed, the control cover 2 needs to be disassembled. During installation, press the pressing plate 13 in advance so that the right end of the cross block 11 is aligned with the cross slot of the subframe 10. Insert the subframe 10 into the inner wall of the control box 1 and insert the right end of the cross block 11 into the horizontal opening of the cross slot of the subframe 10. When the vertical opening of the cross slot of the subframe 10 is aligned with the raised portion at the left end of the cross block 11, release the pressing plate 13 and use the reverse elastic force of the positioning spring 12 to move the pressing plate 13 and the cross block 11 to the right and reset them, so that the raised portion at the left end of the cross block 11 is locked into the vertical opening of the cross slot of the subframe 10.
