[0033] The specific content of this utility model will be further explained in detail below with reference to the embodiments. Detailed Implementation

[0034] It should be noted that, unless otherwise specified, all mechanical equipment and parts in this utility model are based on existing mechanical equipment and parts.

[0035] Following the above technical solution, the following are specific embodiments of this utility model. It should be noted that this utility model is not limited to the following specific embodiments, and all equivalent modifications made based on the technical solution of this application fall within the protection scope of this utility model.

[0036] Example 1:

[0037] This embodiment provides a water quality testing device that facilitates probe replacement, including a slide rail 1, multiple sliders 2 mounted on the slide rail 1, and connectors 3 and probes 4 mounted on adjacent sliders 2, respectively. Figures 1 to 9 As shown, the male end face of the connector 3 is provided with a plurality of circumferentially distributed plug blocks 5 along its own central axis. The plug blocks 5 are provided with plug grooves 501 that are recessed inward from the end face of the plug blocks 5. The gap between the plurality of circumferentially distributed plug blocks 5 is the interface 6. The interface 6 is provided with a data transmission plug terminal 7.

[0038] like Figure 6 As shown, a snap-fit ​​assembly 502 is provided in the insertion slot 501.

[0039] like Figures 1 to 5 As shown, a docking block 8 corresponding to the docking interface 6 is provided in the middle of the female end face of the probe 4. A data transmission interface 9 corresponding to the data transmission plug terminal 7 is provided in the docking block 8. A latch 10 is also provided on the female end face of the probe 4. A latch hole 11 is provided on the latch 10. The position of the latch 10 corresponds to the position of the plug slot 501.

[0040] like Figures 1 to 9 As shown, the connector 3 and the probe 4 are connected to the locking hole via the snap-fit ​​assembly 502.

[0041] like Figure 6 As shown, the buckle assembly 502 includes an elastic element 50201, the position of which corresponds to the position of the insertion slot 501. A torsion spring 50202 is provided on one side of the elastic element 50201, and an L-shaped hook 50203 is sleeved on the torsion spring 50202. An electromagnetic coil 50204 is provided on the side of the hook 50203 for attracting or releasing the hook 50203. The electromagnetic coil 50204 causes the front end of the hook 50203 to exit or engage with the buckle hole 11.

[0042] like Figure 1 and Figure 2 As shown, the plug-in block 5 is also provided with a notch 503.

[0043] like Figure 1 and Figure 4 As shown, a boss 12 with the same shape as the notch 503 is also provided on the female end face of the probe 4. The mating and engaging of the notch 503 and the boss 12 can further ensure the airtightness and firmness of the connection. At the same time, the boss 12 is located on the outside of the female end face of the probe 4, which can protect the latch 10 from damage.

[0044] like Figure 8 As shown, the slider 2 is also equipped with clamping plates 13. Two clamping plates 13 are arranged on opposite sides of the top surface of the slider 2, and the surface of the clamping plates 13 is parallel to the sliding direction of the slide rail 1. The clamping plates 13 are arranged so that the top surface of the slider 2 is aligned with the two clamping plates 13. The shape of the U-shaped clamping cavity is adapted to the shape of the plug-in block 5 and the probe 4. When it is necessary to install the plug-in block 5 and the probe 4, the plug-in block 5 and the probe 4 can be inserted into the corresponding clamping cavity respectively, which makes the installation of the plug-in block 5 and the probe 4 convenient, time-saving and labor-saving.

[0045] like Figure 9 As shown, the slide rail 1 and the slider 2 are connected by a pulley group 14. A pulley group 14 is provided on both sides of the joint between the slide rail 1 and the slider 2. The pulley group 14 can slide along the slide rail 1, so that the slider 2 can slide more smoothly on the slide rail 1.

[0046] In this embodiment, two plug blocks 5 are preferred, which facilitates the manufacture of the plug 3 and also allows the plug 3 to firmly fix the probe 4.

[0047] In this preferred embodiment, the opposing surfaces of the plug-in block 5 are a first surface 504 and a second surface 505 that form an obtuse angle with each other. The first surface 504 and the second surface 505 give the axial cross-section of the plug-in block 5 a shape that is narrow in the middle and wide at both sides, thus creating a region in the interface 6 that is wide in the middle and narrow at both sides, facilitating the placement of the data transmission plug-in terminals 7. Simultaneously, the placement of the first surface 504 and the second surface 505 that form an obtuse angle corresponds to, for example... Figure 4 As shown, the radial cross-section of the mating block 8 on the probe 4 can also be adapted to this shape. When the mating block 8 is inserted into the mating interface 6, as... Figure 2 As shown, the first surface 504 can provide a downward blocking force to the mating block 8, and the second surface 505 can provide an upward blocking force to the mating block 8, so as to prevent the mating block 8 from slipping off from above or below, and to ensure that the mating block 8 can be firmly fixed.

[0048] In this embodiment, the control panel on the main body of the water quality testing device is connected to the drive mechanism, which is in turn connected to the slider 2. The control panel has a control button for controlling the drive mechanism, thereby controlling the slider 2 to slide. By pressing the control button, the drive mechanism can be driven to move the slider 2. In actual installation, the connector 3 is placed on one slider 2, and the probe 4 is placed on the other slider 2. The two sliders 2 are slidably mounted on the slide rail 1. By sliding the sliders 2, the connector 3 and probe 4 can slide along the slide rail 1. When the connector 3 and probe 4 move relative to each other, the latch 10 extends into the connector slot 501 on the connector block 3. The front end of the latch 10 abuts against the elastic element 50201, compressing the elastic element 50201. The electromagnetic coil 50204 releases the hook 50203. Figure 6 The position of the hook 50203, shown by the solid line, allows its front end to engage with the locking hole 11 on the latch 10, locking the latch 10 in place. The mating block 8 on the probe 4 engages with the mating interface 6 in the middle of the connector 3. The data transmission connector 7 within the mating interface 6 is inserted into the data transmission connector 9 within the mating block 8, ensuring the stability and reliability of the probe 4's measurement data transmission, thus achieving the locking and connection between the probe 4 and the connector 3. When the connector 3 and probe 4 move in opposite directions, the electromagnetic coil 50204 attracts the hook 50203, causing its front end to disengage from the locking hole 11 on the latch 10. Figure 6The position of the hook 50203 shown by the dotted line is such that the elastic element 50201 releases the compressive force, giving the latch 10 a pushing force, causing the latch 10 to exit the insertion slot 501. The mating block 8 on the probe 4 exits the mating interface 6 in the middle of the connector 3, and the data transmission plug terminal 7 set in the mating interface 6 exits the data transmission plug interface 9 set in the mating block 5, thus realizing the separation of the probe 4 from the connector 3.
