DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] See also Figure 1-Figure 5 The utility model provides a technical solution: a water sampling component of a dissolved oxygen analyzer, comprising a display 1 and a contact 4 connected to the display 1, and the water sampling component of the dissolved oxygen analyzer also includes:

[0030] A rotating shaft 5 movably arranged in a rotating groove on the side of the display 1;

[0031] A slide bar 6 connected to the rotating shaft 5;

[0032] A clamping assembly movably connected to the slide bar 6, the clamping assembly is used to fix the contact 4, and a storage cavity 20 for storing the rotating shaft 5, the slide bar 6, the clamping assembly and the contact 4 is opened on the side of the display 1. Pressing the rotating shaft 5 to retract into the rotating groove can drive the slide bar 6, the clamping assembly and the contact 4 to enter the storage cavity 20 synchronously;

[0033] The above technical solution can be used to conveniently store the rotating shaft 5, the sliding rod 6, the clamping assembly and the contact 4 in the storage cavity 20 of the display 1 during transportation, forming an integrated structure, which is convenient for carrying and transportation.

[0034] like Figure 4 As shown, in this embodiment, the clamping assembly includes a clamping body 14, and the clamping body 14 is provided with at least two clamping structures, and the clamping structures include: a movable rod 15, which is slidably arranged in a movable groove 16 opened in the clamping body 14; a clamping plate 17, which is connected to one end of the movable rod 15; a connecting plate 18, which is connected to the other end of the movable rod 15; a first elastic member 19, one end of which is connected to the connecting plate 18, and the other end of the first elastic member 19 is connected to the clamping body 14; the clamping assembly also includes a sliding body 7 rotatably connected to the clamping body 14, and the sliding body 7 is provided with a sliding groove 8 for the sliding rod 6 to pass through;

[0035] The above technical scheme can be used to conveniently adjust the length and angle of the contact 4 relative to the sliding rod 6, so as to facilitate quick storage. When in use, first pull the sliding rod 6 to pull the rotating shaft 5 out of the sliding rod 6, push the sliding body 7 to slide along the sliding rod 6, adjust the clamp body 14 to a suitable distance, rotate the rotating shaft 5 to adjust the sliding rod 6 to a suitable angle, push the clamp plate 17 to loosen it, place the contact 4 between the clamp plates 17, loosen the clamp plate 17, and under the elastic action of the first elastic member 19, the clamp plate 17 clamps the contact 4, rotates the clamp body 14 to make the contact 4 vertical, uses a wire to connect the display 1 to the contact 4, pushes the contact 4 downward so that its end is inserted into the water sample, thereby performing detection. After the detection is completed, rotate the clamp body 14 to make the contact 4 and the sliding rod 6 parallel and overlap with each other, press the rotating shaft 5 to retract into the rotating groove, and the sliding rod 6, the clamping assembly and the contact 4 can be driven to enter the storage chamber 20 synchronously. There is no need to disassemble the sliding rod 6, the clamping assembly and the contact 4 for placement, which is convenient for carrying and transportation.

[0036] Further, such as Figure 5 As shown, the clamping assembly further includes: a slider 10, which is slidably disposed in the inner groove 9 provided in the sliding body 7; a pressure plate 12, which is connected to one end of the slider 10; a second elastic member 11, which is disposed in the inner groove 9 and abuts against the other end of the slider 10; and an anti-slip protrusion 13 is disposed on the surface of the pressure plate 12 to increase the friction coefficient between the pressure plate 12 and the slide rod 6;

[0037] The above technical solution can prevent the sliding body 7 from sliding due to accidental touch. Since the pressure plate 12 is provided, the second elastic member 11 can push the slider 10 to slide, and the slider 10 drives the pressure plate 12 to move, so that the pressure plate 12 is close to the slide rod 6, thereby preventing the sliding body 7 from loosening.

[0038] Further, such as Figure 1 and Figure 3 As shown, a storage cavity 2 is provided on one side of the display 1 to accommodate the wires of the contact 4, and a revolving door 3 is provided outside the storage cavity 2;

[0039] The above technical solution can be used to store the wires. After the detection is completed, the wires are unplugged and placed in the storage cavity 2.

[0040] Working principle: When in use, first pull the slide bar 6 to pull the shaft 5 out of the slide bar 6, push the sliding body 7 to slide along the slide bar 6, adjust the clamp body 14 to a suitable distance, rotate the shaft 5 to adjust the slide bar 6 to a suitable angle, push the clamp plate 17 to loosen it, place the contact 4 between the clamp plates 17, loosen the clamp plate 17, and under the elastic action of the first elastic member 19, the clamp plate 17 clamps the contact 4, rotate the clamp body 14 to make the contact 4 vertical, use a wire to connect the display 1 to the contact 4, push the contact 4 downward so that its end is inserted into the water sample, so as to perform detection. After the detection is completed, rotate the clamp body 14 to make the contact 4 and the slide bar 6 parallel to each other, unplug the wire, and put the wire into the storage cavity 2, press the shaft 5 to retract it into the rotating groove, which can drive the slide bar 6, the clamping assembly and the contact 4 to enter the storage cavity 20 synchronously, so that the instrument is integrated and easy to carry.
