[0028] Bolts 2 are provided on the surface of the fixing plate 1, and the fixing plate 1 is installed on the equipment by means of the bolts 2. The shell 3 and the fixing plate 1 are rotatably connected, so that the shell 3 can be rotated downward by ninety degrees after the restriction of the restriction mechanism is released, and the side of the shell 3 close to the fixing plate 1 is set to an open state, and the control panel 4 is inserted into the shell 3 from the front side of the shell 3. The controller components are fixed on the control panel 4, so when the shell 3 is rotated downward by ninety degrees, the controller components can be directly exposed. At the same time, the control panel 4 is directly inserted into the shell 3, and the heat dissipation mechanism is installed on the shell 3, so the control panel 4 can be directly pulled out. With this split structure, it is convenient to replace or repair the components and the heat dissipation mechanism of the control panel 4 separately, which is convenient for operation, enhances the flexibility of the overall operation, and reduces the replacement and maintenance costs.

[0029] Reference Figure 1 , Figure 2 , Figure 4 The heat dissipation mechanism includes a motor 8. Two circular holes are provided at the upper and lower ends of the shell 3, and filters 10 are provided inside the circular holes. A connecting frame is fixedly connected to the circular hole at the top of the shell 3. The motor 8 is installed on the top of the shell 3. The output end of the motor 8 is connected to the connecting shaft 13. The other end of the connecting shaft 13 rotates through the connecting frame and then extends into the shell 3. A turntable 12 and a fan blade 11 are installed in sequence on the connecting shaft 13 in the shell 3. The two turntables 12 are connected by a belt drive.

[0030] When the heat dissipation mechanism is in use, the motor 8 is directly started, the motor 8 drives the connecting shaft 13 to rotate, the connecting shaft 13 drives the turntable 12 to rotate, and the two connecting shafts 13 rotate synchronously through the belt and the turntable 12, so that the two fan blades 11 can be driven to rotate synchronously, thereby achieving the purpose of dissipating the heat of the control panel 4 components inside the shell 3, the circular holes have a ventilation effect, the internal filter 10 serves the purpose of filtering dust, and the connecting frame serves the purpose of installing the connecting shaft 13.

[0031] Reference Figure 7The limiting mechanism includes an L-shaped rod 5 and a rotating rod 6. The L-shaped rod 5 is installed on the fixed plate 1 on both sides of the upper end of the shell 3, and the rotating rod 6 is rotatably connected to the grooves on both sides of the upper end of the shell 3, and the other end of the rotating rod 6 is adaptively connected to the L-shaped rod 5.

[0032] When the limiting mechanism is in use, when it is necessary to rotate the shell 3 downward, first rotate the two rotating rods 6 upward to release the two rotating rods 6 from the restriction of the L-shaped rod 5. At this time, the shell 3 can be directly rotated downward. When it is necessary to fix the shell 3 on the fixing plate 1, the two rotating rods 6 can be rotated to the inside of the L-shaped rod 5, and the L-shaped rod 5 is used to restrict the rotating rod 6, so that the shell 3 cannot rotate downward.

[0033] Reference Figure 3 The control panel 4 is fixed with two plug rods 7 at the bottom of one side close to the housing 3, and a plug hole is provided on the bottom wall of the housing 3, and the plug hole and the plug rod 7 are adapted to be plugged and connected. The control panel 4 is fixed to the housing 3 by the plug rod 7, which serves the purpose of stable connection.

[0034] Reference Figure 5 A receiving groove 15 is provided on the surface where the shell 3 and the upper part of the control panel 4 meet. After the T-shaped block 16 is slidably installed in the receiving groove 15 through the spring 14, one end of the T-shaped block extends out of the shell 3 and is adapted to be connected with the limiting groove provided on the upper end surface of the control panel 4.

[0035] The top of the control panel 4 is restricted by a T-shaped rod to enhance the stability of the control panel 4 after insertion. The spring 14 can cause the T-shaped rod to be subjected to a downward force, thereby preventing the T-shaped rod from easily leaving the restriction groove at the top of the control panel 4.

[0036] Reference Figure 2 , Figure 3 A groove is provided on the bottom wall of the shell 3, and a fixing block 9 is installed on the control panel 4 at a position corresponding to the groove, and the surface of the fixing block 9 is a concave arc structure.

[0037] A space for the wire to pass through is formed between the groove and the fixing block 9 , so that the wire can enter and exit the interior of the housing 3 conveniently.

[0038] Reference Figure 3 The surface of the fixing block 9 is provided with a rubber pad, and the setting of the rubber pad makes the wire subject to extrusion force, thereby reducing the phenomenon that the wire is pulled outside and causes the wire to fall off from the internal components.
