Pressing the button on the button module 2 locks the distance between the ultrasonic probe 4 and the object being measured, facilitating measurement and reading.

[0035] Therefore, the ultrasonic rangefinder demonstration teaching aid of this utility model modularizes electronic and structural components. When used as a demonstration teaching aid, it is easy to disassemble and assemble, which makes it convenient for teachers to explain and for students to operate, thereby increasing students' sense of participation in learning and making the teaching application effect more ideal.

[0036] Specifically, the ranging adapter plate 3 is provided with an interface, and the ultrasonic probe 4 is provided with a pin. The ultrasonic probe 4 is connected to the ranging adapter plate 3 via the pin in a pluggable manner, which facilitates disassembly and assembly.

[0037] Specifically, the mounting section includes a first mounting ring 7 and a second mounting ring 8. A first multi-hole mounting panel 9 is fixed inside the first mounting ring 7, and a second multi-hole mounting panel 10 is fixed inside the second mounting ring 8. The four-digit LED display module 1 and the button module 2 are detachably mounted on the first multi-hole mounting panel 9, and the ranging adapter plate 3 and the circuit board 6 are detachably mounted on the second multi-hole mounting panel 10. This structure of the mounting section facilitates the installation of the four-digit LED display module 1, the button module 2, the ranging adapter plate 3, and the circuit board 6.

[0038] The first connecting ear 701 is fixed at the bottom of the first mounting ring 7, and the second connecting ear 801 is fixed at the bottom of the second mounting ring 8. The first connecting ear 701 and the second connecting ear 801 are respectively located at the upper ends of the front and rear sides of the battery box 5, and the first connecting ear 701, the battery box 5 and the second connecting ear 801 are connected and fixed by bolts, which makes disassembly and assembly convenient.

The ranging adapter board 3 and the circuit board 6 are respectively mounted on the second multi-hole mounting panel 10 with screws, making them easy to install and remove.

[0040] Specifically, battery box 5 contains batteries that power the ultrasonic rangefinder demonstration tool. A switch is also located on battery box 5 to control the battery's power supply.

[0041] Specifically, the left and right sides of the first porous mounting panel 9 form a first side mounting gap 702 with the first mounting ring 7, and the lower side of the first porous mounting panel 9 forms a first lower mounting gap 703 with the first mounting ring 7.

The second annular cover plate 12 is detachably installed to the second mounting hole 804 by screws. Since both the first annular cover plate 11 and the second annular cover plate 12 are annular structures, they prevent the installation of the four-digit digital tube module 1, the button module 2, the ranging adapter board 3, and the circuit board 6, while also providing a certain degree of protection for the front and rear sides of the mounting part.

[0044] like Figure 7 and Figure 8 As shown, the circuit working principle on circuit board 6 is as follows: the power supplied by battery box 5 is input through the power interface on circuit board 6; the button interface on circuit board 6 is used to connect with the connection line of button module 2; circuit board 6 is provided with ECHO port and TRIG port respectively, which are used to connect with ECHO port and TRIG port of ranging adapter board 3 respectively through connection lines; circuit board 6 is provided with CLK port and DIO port respectively, which are used to connect with CLK port and DIO port of four-digit digital tube module 1 respectively through connection lines; the ultrasonic ranging chip U1 on circuit board 6 is used to process the measurement data of ultrasonic probe 4 and then display the measurement data through four-digit digital tube module 1.

[0045] In this embodiment, all connecting lines are 3-pin lines, and each 3-pin line has two OT terminals. Using 3-pin lines simplifies the connection of the lines, increases stability, and reduces the difficulty of operation.
