[0023] A control board 17 is provided inside the housing 14, and a shock-absorbing pad 18 is provided between the instrument housing 11 and the control board 17. The instrument housing 11 and the control board 17 are installed by bolts 19. The instrument housing 11 and the control board 17 are fixed by bolts 19 using front and rear double nuts 19 to tightly fit the rotary potentiometer body 12 to the instrument housing 11.

[0024] A connection slot 141 is provided at the rear end of the housing 14. The surface of the control board 17 is provided with an output terminal A121, an output terminal B122, a positive power supply electrode 15 and a negative power supply electrode 16. The output terminal A121 and the output terminal B122 can be arbitrarily selected for connection.

[0025] In this embodiment: the display screen 13 is linearly synchronized with the rotary potentiometer body 12, and the display screen 13 is designed to be installed on the instrument case 11. A hole can be easily opened on the device, and the installation on the device is more firm and durable. The instrument case 11 and the control panel 17 are fixed with bolts 19 using front and rear double nuts 19 to tightly fit the rotary potentiometer body 12 to the instrument case 11. When in use, the force point of the product will not be concentrated only on the knob shaft of the rotary potentiometer body 12. The rotary potentiometer body 12 is not easily damaged and is more durable. The visual potentiometer device 1 installs the output terminal A121 on the rotary potentiometer body 12 together with the rotary potentiometer body 12. Customers can choose the wiring installation method according to their own application requirements, which is more convenient and extensive to use.

[0026] Example 2: Please refer to Figure 2-4 A dustproof net B145 is installed at the rear end of the shell 14 and on the outside of the connecting groove 141, and an insert ring 146 is installed at the lower end of the dustproof net B145. A nut 147 is installed inside the insert ring 146. The insert ring 146 and the shell 14 are installed with the nut 147, and the connecting groove 141 is dustproofed with the dustproof net B145.

[0027] A rubber ring 148 is installed at the middle end of the dustproof net B145, and there are multiple groups of rubber rings 148. The multiple groups of rubber rings 148 are arranged corresponding to the middle ends of the output terminal A121, the output terminal B122, the positive power pole 15 and the negative power pole 16, so that the data line passes through the rubber ring 148 and is connected to the interface of the rotary potentiometer body 12, the positive power pole 15 or the negative power pole 16.

[0028] Grooves 142 are provided on both sides of the inner wall of the shell 14 and above the rotary potentiometer body 12. A dustproof net A144 is installed inside the grooves 142. A heat absorbing component 143 is installed inside the shell 14 and above the grooves 142. The grooves 142 are used to dissipate the heat generated by the operation of the internal components of the shell 14.

[0029] The heat absorption component 143 includes a U-shaped plate 1431 installed below the row groove 142, and a bevel groove 1432 is opened inside the U-shaped plate 1431, and the bottom end of the bevel groove 1432 is aligned with the bottom end of the row groove 142. The inner wall of the shell 14 and above the U-shaped plate 1431 are symmetrically installed with a heat absorption inclined plate A1433 and a heat absorption inclined plate B1434. The heat inside the shell 14 is absorbed by the heat absorption inclined plate A1433 and the heat absorption inclined plate B1434.

[0030] In this embodiment: the heat generated by the visualized potential device 1 during operation flows to the upper end of the upper shell 14. When the heat passes through the heat absorbing member 143, the heat absorbing inclined plate A1433 and the heat absorbing inclined plate B1434 absorb the heat. During long-term use, water droplets are generated on the outer surfaces of the heat absorbing inclined plate A1433 and the heat absorbing inclined plate B1434. The water droplets flow to the inside of the U-shaped plate 1431 along the inclined heat absorbing inclined plate A1433 and the heat absorbing inclined plate B1434. The U-shaped plate 1431 collects the water droplets. Since the bottom end of the inclined groove 1432 is inclined, the water droplets can be discharged to the inside of the discharge groove 142 and discharged therefrom, thereby discharging the heat. The dustproof net A144 inside 142 prevents the interior of the shell 14 from dust, performs dust-proof treatment on the parts, and protects the parts. When the visual potential device 1 is used, the nut 147 can be pulled out, and the lower end of the dustproof net B145 can be opened. The operator can pass the data cable through the rubber ring 148 and wrap the connecting end of the data cable around the outside of the output terminal A121, the output terminal B122, the positive power pole 15 or the negative power pole 16. After the data cable is connected, the nut 147 is inserted into the inside of the mounting ring 146 and fixed to the rear end of the shell 14. The dustproof net B145 covers the outside of the connecting groove 141 to prevent the interior of the shell 14 from dust.

[0031] Working principle: The rotary potentiometer body 12 is tightly attached to the instrument housing 11. When in use, the force point of the product will not be concentrated only on the knob shaft of the rotary potentiometer body 12. The rotary potentiometer body 12 is not easy to be damaged and is more durable. The visual potentiometer device 1 installs the output terminal A121 on the rotary potentiometer body 12 together with the rotary potentiometer body 12. Customers can choose the wiring installation method according to their own application requirements. It is more convenient and extensive to use. The heat path heat absorbing component 1 43, the heat absorbing inclined plate A1433 and the heat absorbing inclined plate B1434 absorb heat, and water droplets are generated on the outer surfaces of the heat absorbing inclined plate A1433 and the heat absorbing inclined plate B1434, and the water droplets flow to the inside of the U-shaped plate 1431 along the inclined heat absorbing inclined plate A1433 and the heat absorbing inclined plate B1434, and the U-shaped plate 1431 is used to collect the water droplets. Since the bottom end of the inclined groove 1432 is inclined, the water droplets can be discharged to the inside of the discharge groove 142 and discharged therefrom to discharge heat.
