[0003] In actual applications, it is often necessary to further process the water quality parameters collected by the water quality sensor. In this way, it is necessary to couple with the microprocessor together with the water quality sensor. The structure formed after the microprocessor is coupled with the water quality sensor often needs to be encapsulated in a hollow container for more convenient use. The hollow container is mainly formed by a box body with an open top and a top cover. At present, the box body and the top cover are often connected by several tension screws. The operation is cumbersome and time-consuming during assembly and disassembly, and special tools are also required. The operation is difficult. Moreover, in a poor environment, the tension screws are often corroded, and they often become loose after a long time. As a result, the connection stability between the box body and the top cover is weakened, and the sealing function is weakened, which is not suitable for the work of the microprocessor and the water quality sensor.

[0033] Next, the present utility model will be preferably described in conjunction with the drawings and embodiments.

[0034] Such as Figures 1 to 7As shown in the figure, a coupling device for a water quality sensor and a microprocessor according to the present utility model includes:

[0035] A box body 211 with an open top and a top cover 212. An opening 213 with a trapezoidal longitudinal section is formed in the top wall of the box body 211. A protruding member 214 with a trapezoidal longitudinal section is arranged on the bottom wall of the top cover 212, and the protruding member 214 matches the opening 213. Clamping interfaces 215 are formed on the outer walls of the four sides of the protruding member 214;

[0036] A display screen is embedded on one side wall of the box body 211. The display screen is connected to a microprocessor and a water quality sensor arranged in the box body. The probe of the water quality sensor extends out of the box body 211, and both the water quality sensor and the display screen are connected to the microprocessor.

[0037] In a preferred but non-limiting embodiment of the present utility model, the matching of the protruding member 214 and the opening 213 is as follows:

[0038] The protruding member 214 and the opening 213 can be combined in a manner of transitional fit.

[0039] In a preferred but non-limiting embodiment of the present utility model, hollow rectangular members 216 are assembled on the outer walls of the four sides of the box body 211. Clamping blocks 217 are arranged in the hollow rectangular members 216, and the clamping blocks 217 match the clamping interfaces 215.

[0040] In a preferred but non-limiting embodiment of the present utility model, the matching of the clamping block 217 and the clamping interface 215 is as follows:

[0041] The clamping block 217 and the clamping interface 215 can be combined in a manner of transitional fit.

[0042] In a preferred but non-limiting embodiment of the present utility model, a traction column 218 is arranged on the wall surface of the clamping block 217 farther from the clamping interface 215. A through hole is formed in the wall surface of the hollow rectangular member 216, and the head of the traction column 218 extends out of the through hole to the outer wall of the hollow rectangular member 216.

[0043] In a preferred but non-limiting embodiment of the present utility model, reciprocating cylinders 219 are assembled on two sides in the hollow rectangular member 216. The heads of the reciprocating cylinders 219 are connected to the clamping blocks 217. Disc springs 220 are wound around the outer walls of the reciprocating cylinders 219, and the two ends of the disc springs 220 are respectively in contact with the inner wall of the hollow rectangular member 216 and the clamping block 217.

[0044] When assembling the top cover 212, first insert the protruding part 214 at the lower part of the top cover 212 into the opening 213, and then let the two pairs of clamping blocks 217 be inserted into the two pairs of clamping ports 215 respectively. In this way, the top cover 212 can be stabilized in all directions around, improving the firmness of connection. And under the traction of the disc spring 220, the clamping blocks 217 can always be driven, so as to ensure the firmness of the connection between the clamping blocks 217 and the clamping ports 215, so that the top cover 212 will not become loose after assembly. When disassembling the top cover 212, just pull the traction column 218 outwards, so that the clamping blocks 217 are removed from the clamping ports 215, and then the top cover 212 can be directly taken off from the upper part of the casing 211. By arranging the reciprocating cylinder 219, the disc spring 220 can be positioned, preventing the disc spring 220 from being distorted during use, and improving its service function and service life.

The traction column 218 is rotatably connected to the clamping block 217. Since the number of components such as the clamping ports 215, the clamping blocks 217 and the traction column 218 is two pairs, the top cover 212 can be stabilized in all directions around, so as to ensure the firmness of the assembly of the top cover 212. When disassembling the top cover 212, the traction column 218 can be pulled outwards to pull the clamping block 217 out of the clamping port 215. At this time, the traction column 218 pulls the side piece 312 out of the side port 311. Then rotate the traction column 218 by a certain angle, so that the side piece 312 and the side port 311 cross each other. Then release the traction column 218, and the side piece 312 can stick to the outer wall of the hollow rectangular part 216 to position the clamping block 217, preventing it from being inserted into the clamping port 215 again. Therefore, the function of removing the two pairs of clamping blocks 217 from the two pairs of clamping ports 215 one by one can be achieved, and one person can complete the operation.

The offset pieces 512 and the inclined walls 511 are matched. After the top cover 212 is assembled on the cassette body 211, the offset pieces 512 and the inclined walls 511 are in contact with each other. Due to the arrangement of the inclined walls 511, the situation of liquid flowing in can be greatly isolated, so the sealing performance between the top cover 212 and the cassette body 211 can be further improved.

[0050] In a preferred but non-limiting embodiment of the present utility model, assembly pieces 611 are assembled on the two outer walls of the cassette body 211, and assembly openings 612 are formed in the assembly pieces 611. Through the arrangement of the assembly pieces 611 and the assembly openings 612, the cassette body 211 can be flexibly hung on the bearing wall.

[0051] In a preferred but non-limiting embodiment of the present utility model, the head of the clamping block 217 facing the protruding member 214 is an arched member. When assembling the top cover 212, the protruding member 214 is inserted into the opening 213. The lower part of the opening 213 presses the arched structure of the head of the protruding member 214, so as to drive the clamping block 217 to retract into the hollow rectangular member 216. Until the protruding member 214 is completely inserted into the opening 213 and the clamping interface 215 is aligned with the clamping block 217, under the drive of the disc spring 220, the clamping block 217 can be driven to actively insert into the clamping interface 215, improving the assembly efficiency of the top cover 212.

[0052] In a preferred but non-limiting embodiment of the present utility model, the model of the water quality sensor is MW-TDS101, the model of the display screen is LCD1602, and the model of the microprocessor is STC89C52.

[0053] As Figure 7 shown, it is a schematic circuit connection diagram of the water quality sensor, the display screen and the microprocessor. In this way, the water quality sensor can transmit the water quality data it collects to the microprocessor, and then the microprocessor transmits the water quality data to the display screen for display.

[0055] When assembling the top cover, the protruding member is inserted into the opening. The lower part of the opening presses the arched structure of the head of the protruding member, so as to drive the clamping block to retract into the hollow rectangular member.
