DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] This embodiment provides a motor control device, which is used to control the on and off of the electric energy inside the motor, thereby realizing the control of the motor. The device can facilitate the disassembly of the fixing plate 1 and the outer shell 2, and is very convenient and quick to repair components such as the main board inside the outer shell 2, thereby ensuring the use effect of the motor control device.

[0023] See also Figure 1 to Figure 4 A motor control device includes a fixed plate 1, a shell 2 is arranged on the front of the fixed plate 1, a sealing ring is arranged between the fixed plate 1 and the shell 2, which can ensure the sealing between the fixed plate 1 and the shell 2, and a main board and other control components are installed inside the shell 2, which can facilitate the control of the motor.

[0024] A group of mounting plates 9 are fixedly connected to the outer surface of the fixing plate 1. A mounting hole 10 is opened on the front of each mounting plate 9. Fixing bolts are passed through the inside of the mounting hole 10 so that the fixing bolts are connected to external equipment, which can facilitate the installation of the device.

[0025] Two symmetrical tensioning components 3 are installed between the fixed plate 1 and the outer shell 2. The tensioning component 3 includes a hollow groove 301 and a connecting plate 302. The hollow groove 301 is opened on the outer surface of the fixed plate 1, and the connecting plate 302 is installed on the outer surface of the outer shell 2. The outer surface of the connecting plate 302 is provided with a square groove 303. The inner wall of the hollow groove 301 is rotatably connected with a rotating shaft 304. The outer surface of the rotating shaft 304 is installed with a tension bolt 305. The end of the tension bolt 305 away from the rotating shaft 304 is threadedly connected with a nut 306, and the nut 306 is in contact with the connecting plate 302.

[0026] Tightening the nut 306 can pull the connecting plate 302 and the rotating shaft 304, which can facilitate the installation between the fixing plate 1 and the outer shell 2. When the fixing plate 1 and the outer shell 2 need to be disassembled, loosening the nut 306 and then rotating the tension bolt 305 can release the limit between the fixing plate 1 and the outer shell 2, which can facilitate the disassembly between the fixing plate 1 and the outer shell 2.

[0027] A display screen 4 is fixedly embedded on the front of the housing 2. The display screen 4 can be used to conveniently observe the control status of the motor. A knob switch 5 is installed on the front of the housing 2. Turning the knob switch 5 can conveniently control the motor.

[0028] Two symmetrical heat dissipation grooves 6 are provided on the right side of the shell 2, and filter screen 1 7 is installed on the inner walls of the two heat dissipation grooves 6. Two symmetrical exhaust components 8 are installed on the left side of the shell 2. The exhaust components 8 include an air outlet pipe 801, a filter screen 2 802 and an exhaust fan 803. The air outlet pipe 801 is fixedly embedded in the left side of the shell 2, and the filter screen 2 802 and the exhaust fan 803 are both installed on the inner wall of the air outlet pipe 801.

[0029] The exhaust fan 803 can discharge the air inside the shell 2 through the air outlet 801, so that the external air can enter the inside of the shell 2 through the heat dissipation slot 6, which can effectively dissipate the heat inside the shell 2 and ensure the heat dissipation effect of the device. The filter 1 7 and filter 2 802 can prevent dust in the air from entering the inside of the shell 2, thereby preventing dust from damaging the components inside the shell 2.

[0030] The upper surface and the bottom surface of the shell 2 are fixedly embedded with heat conducting plates 11, and a group of heat dissipating fins 12 arranged at equal distances are installed on the side of the two heat conducting plates 11 away from each other. The heat conducting plates 11 can transfer the heat inside the shell 2 to the heat dissipating fins 12, which can facilitate the heat dissipation of the inside of the shell 2 and ensure the heat dissipation effect of the device.

[0031] Working principle: When the device is in use, a fixing bolt is passed through the inside of the mounting hole 10 so that the fixing bolt is connected to an external device, which can facilitate the installation of the device. The motor to be controlled is electrically connected to the main board inside the housing 2 through a wire, so that the device can control the motor. The exhaust fan 803 can exhaust the air inside the housing 2 through the air outlet 801, so that the external air can enter the inside of the housing 2 through the heat dissipation slot 6, which can effectively dissipate the heat inside the housing 2 and ensure the heat dissipation effect of the device. When the housing needs to be repaired, When repairing the components such as the main board inside 2, first rotate the two nuts 306. By utilizing the threaded fit between the tension bolts 305 and the nuts 306, the nuts 306 can be rotated to move away from the connecting plate 302. Then, the tension bolts 305 can be rotated around the rotating shaft 304 inside the empty groove 301, so that the tension bolts 305 can be disengaged from the inside of the square groove 303, and the limit on the housing 2 can be released, so that the fixing plate 1 and the housing 2 can be easily disassembled, and the interior of the housing 2 can be easily repaired.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
