[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] like Figure 1-5 As shown, a displacement measuring device includes several electrical components 7, and the electrical components 7 include capacitors, resistors, relays, diodes, triodes, connectors, etc. These are commonly used components on electronic boards and are used to ensure the smooth operation of the electronic boards. In addition, the electrical components 7 also include ultrasonic modules, display modules, temperature sensors and chips. The chip part uses a single-chip microcomputer Arduino, which is cheap and has relatively abundant IO pins, and can fully meet the requirements of this displacement test. The measurement principle of the chip is to output a signal to the ultrasonic module US-100 through the digital IO output signal, trigger a 40Khz ultrasonic signal, and then introduce the ultrasonic signal into the single-chip microcomputer through the input IO point. By measuring the time difference twice, the distance measured by the word can be calculated. The formula is as follows:

[0024] H = 340m / s*t;

[0025] If the heights of the two measurements are h1 and h2 respectively, then the unit time difference within the △t time is (h1-h2) / △t; for the measuring cylinder, the unique height value corresponds to the unique capacity, so h1 corresponds to v1, h2 corresponds to v2, and the unit time measuring cylinder price change rate = (v1-v2) / △t. Through the LCD1602 display module connected to the Arduino system, the displacement value can be accurately displayed on the display screen, and the process operator can accurately read the displacement of the chemical pump:

[0026] In order to facilitate the connection of these electrical components 7, specifically: it also includes an insulating plate 1, a connecting strip 5 is installed on one side of the surface of the insulating plate 1, and a bottom card seat 15 and a high card seat 16 are fixedly connected on both sides of the surface of the connecting strip 5, and an electrode seat 6 corresponding to a plurality of electrical components 7 and electrically connected through a wire is inserted between the bottom card seat 15 and the high card seat 16, and a conductive seat 12 is fixedly connected to the electrode seat 6, and a plurality of insulating pressure plates 13 are installed on the electrode seat 6 through an elastic hinge, and the insulating pressure plate 13 is used to press the wire tightly on the conductive seat 12. 7 is electrically connected to an electrode holder 6, and one end of the connecting wire is electrically connected to the electrical device 7, and the other end is tightly attached to the surface of the conductive holder 12 through the insulating pressure plate 13. In addition, the surface of the conductive holder 12 is serrated, and other wires can be independently installed using the teeth on its surface, and then the electrical devices 7 with different functions can be connected through other wires to form a complete circuit. In addition, the height difference between the bottom holder 15 and the high holder 16 can allow personnel to directly pull out the electrode holder 6 at the corresponding position, and the electrode holder 6 itself is made of insulating material.

[0027] In order to facilitate the installation of the electrical device 7, it is further discussed that: a plurality of through holes 2 are provided on the surface of the insulating plate 1, and a plurality of T-shaped columns 3 inserted into the through holes 2 are provided around each electrical device 7 on the insulating plate 1, and a metal wire 8 for fixing the electrical device 7 is provided between two T-shaped columns 3 on the same side at both sides of the electrical device 7, and a winding column 4 for connecting the end face of the metal wire 8 is fixedly connected to the bottom surface of the T-shaped column 3, and a through groove 17 is provided on the side of the T-shaped column 3, and a V-shaped block 9 is symmetrically installed in the through groove 17. As shown in the figure, the head of the T-shaped column 3 is located on one side of the insulating plate 1, and the V-shaped block 9 is located on the other side of the insulating plate 1. On the other side of the insulating board 1, the elastic hinge can be used to realize that the corner of the V-shaped block 9 extends out of the through slot 17 and fits with the other side of the insulating board 1, so it is easy to fix the T-shaped column 3 on the insulating board 1. Conversely, when removing the T-shaped column 3, it is only necessary to press the V-shaped block 9 so that the V-shaped block 9 is stored in the through slot 17. When the T-shaped column 3 is fixed around the electrical component 7 on the insulating board 1, the metal wire 8 is used to pass through two adjacent T-shaped columns 3 and is wound around the electrical component 7, and the two ends of the metal wire 8 are wound around the winding column 4 on the corresponding T-shaped column 3, and the metal wire 8 can be used to fix the electrical component 7 on the insulating board 1.

[0028] In order to facilitate the disassembly and assembly of the electrode holder 6: the bottom holder 15 and the high holder 16 are both arranged in an L-shaped position, and are staggered with one side facing away from the insulating plate 1. One side of the electrode holder 6 is inserted into the high holder 16, and the other side is embedded with a friction pad 10 inserted into the bottom holder 15. A spring rod 14 is fixedly connected between the friction pad 10 and the inner wall of the electrode holder 6, and a handle 11 is fixedly connected to the surface of the friction pad 10 and is slidably connected to the electrode holder 6. The friction pad 10 is driven by the sliding handle 11 to force the spring rod 14 to elastically shrink and be stored in the electrode holder 6. The friction pad 10 and the bottom clamping seat 15 can be staggered, that is, the electrode seat 6 and the bottom clamping seat 15 can be matched with each other. The formed gap is convenient for sliding the electrode seat 6, so that the electrode seat 6 can be separated from the high clamping seat 16. The electrode seat 6 in the middle position can be removed without moving the electrode seats 6 in other positions. When the electrode seat 6 is between the high clamping seat 16 and the bottom clamping seat 15, the elastic force of the spring rod 14 is used to push the friction pad 10 to fit tightly against the inner wall of the bottom clamping seat 15, and the friction force is used to fix the electrode seat 6 at the corresponding position on the surface of the connecting strip 5.

[0029] Working principle: fix the corresponding electrical components 7 on the insulating plate 1 through the T-column 3, and install the corresponding number of electrode seats 6 on the connecting strip 5, use the wires to contact the electrical components 7 and the conductive seats 12 on the electrode seats 6 to achieve electrical connection, and use the insulating pressure plates 13 at other positions on the conductive seats 12 to press other wires, and use other wires to connect the electrical components 7 that need to be matched, so as to realize the assembly of the electronic board. When the line is damaged, only the damaged wire needs to be replaced.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
