[0034] The following is in conjunction with the appendix Figures 1-9 The present invention will be described in further detail below.

[0035] Example 1, a control box, referring to Figures 1-2 It includes a box 1, which is a rectangular metal shell, and the box 1 is provided with a hinged door 13;

[0036] The box 1 includes a back panel 11, and the back panel 11 and the door 13 are positioned in a front-to-back correspondence.

[0037] The back panel 11 is fitted with the panel 2;

[0038] Reference Figure 3 Panel 2 is a rectangular metal plate. All four edges of panel 2 are bent to form flanges 21. The flanges 21 face the back panel 11. The flanges 21 include side flanges 21, upper flanges 21 and lower flanges 21.

[0039] Panel 2 is equipped with an electronic control component 12 and a wire trough 6; the electronic control component 12 can be a controller, relay, switch, etc., and can be fixed by threaded nails.

[0040] Reference Figure 4 The back plate 11 is welded and fixed with an upper connecting block 31, and the insert rod 32 is fixed to the upper connecting block 31. There are two insert rods 32, and the insert rods 32 are vertically upward.

[0041] The upper flange 21 of panel 2 has an insertion hole 22 for inserting rod 32. The insertion hole 22 is an oval hole; the insertion hole 22 and the insertion rod 32 are set accordingly.

[0042] Insert the plug 32 into the plug hole 22 to suspend the panel 2 on the back plate 11;

[0043] There are two screws, number 42.

[0044] A lower connecting block 41 is welded and fixed to the back plate 11. The lower connecting block 41 has a threaded hole. A screw 42 is inserted under the panel 2. The screw 42 is connected to the threaded hole of the lower connecting block 41. When tightened, the head of the screw 42 presses against the panel 2. There are two screws 42.

[0045] Working principle: The assembler can first place the panel 2 on the operating table and install the electrical control components 12 and the wire trough 6 on the panel 2. The operating table has a more spacious assembly space than the inside of the box 1.

[0046] The assembled panel 2 can be installed on the back plate 11. After the insertion rod 32 and the insertion hole 22 are positioned, the screw 42 is tightened to fix the panel 2 and the back plate 11, which can be done relatively easily.

[0047] In this design, the insertion rod 32 is vertically upward, so the upper flange 21 of the panel 2 can be supported by the insertion rod 32. During the calibration process of the insertion rod 32 and the socket 22, the assembler can easily move the panel 2 to insert the insertion rod 32 into the socket 22.

[0048] Example 2, a control box, differs from Example 1 in that, see below. Figure 6 The side flange 21 of panel 2 has heat dissipation holes 7. The heat dissipation holes 7 are circular holes and are located at the upper and lower parts of the side flange 21. They are mainly used for heat dissipation of panel 2 because the components on panel 2 generate a certain amount of heat when they are working.

[0049] The ventilation holes 7 also serve to provide a place for assembly personnel to insert their fingers so that they can grip the panel 2.

[0050] After the components are installed, the overall weight of panel 2 increases. When the assembler hangs panel 2 into the housing 1, the fingers of the person holding panel 2 can be embedded into the heat dissipation hole 7, which can reduce the difficulty of holding it.

[0051] Since the heat dissipation hole 7 is located on the side flap 21, which is between the front panel 2 and the back panel 11, it is not easy for a finger inserted into the heat dissipation hole 7 to interfere with the contact between the front panel 2 and the back panel 11.

[0052] Reference Figure 7 and Figure 8 The lower connecting block 41 has a lower inclined surface 43 on its downward-facing side, and the lower flange 21 has an upper inclined surface 44. The upper inclined surfaces 44 and the lower flange 21 are fitted together.

[0053] When screw 42 is tightened, the upper inclined surface 44 and the upper inclined surface 44 press against each other, so that panel 2 will be subjected to a downward component force, which makes the vertical constraint of panel 2 more secure.

[0054] Example 3, a control box, differs from Example 2, as described below. Figure 3 The back panel 11 is fixed with a vertical connecting block 51. The vertical connecting block 51 has a side slope 52. The side flange 21 of the panel 2 abuts against the side slope 52. The purpose is to make the side of the panel 2 and the back panel 11 more firmly laterally constrained.

[0055] The contact method between the side flange 21 and the side slope 52 is the same as the contact method between the bottom flange 21 and the lower slope 43.

[0056] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
