[0025] A protection component and a water toxicity analyzer thereof, such as Figure 1 , Figure 2 and Figure 3As shown, it includes a protective shell 10, which forms a box structure with an opening at the top. A sealing cover is hinged on the top of the protective shell 10, which is locked to the protective shell 10 by a buckle to form a sealed chamber. A buffer sponge is installed in the cavity of the protective shell 10, and the sponge is provided with a groove for placing the instrument. The buckle is any model disclosed in the prior art. The protective shell 10 and the sealing cover form a sealed chamber to protect the instrument, which will not be elaborated here.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, the bottom surface of the protective shell 10 is provided with an anti-tilt structure for supporting the protective shell 10, and the anti-tilt structure includes a support body 20, a slide rod 21 and an adjusting screw 25. The support body 20 is fixedly connected to the slide rod 21, and the slide rod 21 is slidably connected to the protective shell 10. The slide rod 21 can slide to the oblique rear of the sealing cover to inhibit the protective shell 10 from tipping backward. The adjusting screw 25 is threadedly connected to the support body 20, and the end of the adjusting screw 25 can touch the ground to form a supporting point. The slide rod 21 forms a rectangular rod structure, and the support body 20 is a rectangular block structure. The end face of the slide rod 21 is fixedly connected to the support body 20. The wall surface of the support body 20 is provided with a threaded hole adapted to the adjusting screw 25, and the threaded hole passes through the support body 20. The adjusting screw 25 is connected to the threaded hole. In this solution,

[0027] By setting the sliding rod 21, the support body 20 is pulled to drive the sliding rod 21 to slide to the rear of the protective shell 10, and the bottom surface of the support body 20 can contact the ground to form a support. When the sealing cover is flipped open, the protective shell 10 can be prevented from tipping backward as a whole, thereby achieving protection for the instruments in the protective shell 10 and having a more stable placement effect. By turning the adjusting screw 25, the end surface of the adjusting screw 25 can contact the ground to adapt to the unevenness of the ground. Even if the support body 20 is above a pit on the ground, the adjusting screw 25 can replace the support body 20 to contact the ground to form a support to prevent the protective shell 10 from tipping backward. In order to ensure the support effect in all directions, four anti-tilt structures can be set on the bottom surface of the protective shell 10, and the four anti-tilt structures are cross-distributed, thereby achieving support and anti-tilt in four directions. The bottom surface of the protective shell 10 is fixedly connected with a supporting foot.

[0028] like Figure 4 and Figure 5As shown, the anti-tilt structure also includes a storage tube 22 and an elastic member 23. The storage tube 22 is fixedly connected to the protective shell 10, and the elastic member 23 is fixedly connected to the slide bar 21. The slide bar 21 can slide along the storage tube 22, and the elastic member 23 can resist the storage tube 22 to limit the sliding of the slide bar 21. The storage tube 22 forms a square tube structure, and the slide bar 21 is adapted to the chamber of the storage tube 22 and slides in the chamber of the storage tube 22. An avoidance groove is provided on the top surface of the slide bar 21, and the elastic member 23 is located in the avoidance groove. One of the end faces of the elastic member 23 is fixedly connected to the inner wall surface of the slide bar 21, and the other end face of the elastic member 23 extends to the outside of the avoidance groove to form a protrusion. Pressing the free end of the elastic member 23 can make the elastic member 23 is deformed and bent toward the avoidance groove. As a supplement to the above scheme, by setting a storage tube 22, the storage tube 22 can provide a limit for the slide bar 21 and store the slide bar 21, so that the slide bar 21 maintains a linear displacement. When the support body 20 is pulled to move, the support body 20 drives the slide bar 21 to slide in the cavity of the storage tube 22, and the position of the support body 20 is adjusted. An elastic member 23 is set. When the slide bar 21 is pushed into the cavity of the storage tube 22, the elastic member 23 itself has a certain elasticity. The elastic member 23 extending upward by tilting contacts the inner top surface of the storage tube 22. The friction between the elastic member 23 and the storage tube 22 limits the sliding of the slide bar 21, thereby locking the position of the slide bar 21, which has a better storage and positioning effect.

[0029] like Figure 4 As shown, the top surface of the elastic member 23 is fixedly connected with a contact block 24, and the contact block 24 can resist the inner wall surface of the storage tube 22 to limit the sliding of the slide bar 21. The contact block 24 is a rubber ball, and the elastic member 23 pushes the contact block 24 to resist the inner top surface of the storage tube 22, so that the slide bar 21 and the storage tube 22 have more sufficient contact force. The contact block 24 can limit the sliding of the slide bar 21 in the cavity of the storage tube 22 to achieve the purpose of locking the position. When the slide bar 21 slides into the cavity of the storage tube 22, it can prevent the slide bar 21 from sliding out of the cavity of the storage tube 22. At the same time, it can lock the distance between the support body 20 and the storage tube 22 to achieve the purpose of adjusting the position of the support body 20.

[0030] A water quality toxicity analyzer, not shown in the figure, includes an analyzer body. The outside of the analyzer body is provided with all the above-mentioned protective components. The analyzer body is placed in the cavity of a protective shell 10. By placing the analyzer in a sponge groove in the cavity of the protective shell 10, the sponge can protect the analyzer body, and an anti-tilt structure is provided on the bottom surface of the protective shell 10, so that when the sealing cover is opened to use the analyzer body, the protective shell 10 is supported and anti-tilted, thereby reducing the probability of the protective shell 10 tipping over and causing the analyzer body to fall and be injured.

[0031] The working principle of the utility model is as follows: the free end of the elastic member 23 is pressed, the elastic member 23 is deformed and bent downward in the avoidance groove, and the abutment block 24 is separated from the inner wall surface of the storage tube 22, and the support body 20 is pulled to drive the slide bar 21 to slide to the rear of the protective shell 10, and the bottom surface of the support body 20 can contact the ground to form a support, and the adjusting screw 25 is rotated, and the end surface of the adjusting screw 25 can contact the ground to adapt to the unevenness of the ground, and when the sealing cover is flipped open, the protective shell 10 can be prevented from tilting backward as a whole;

[0032] When storing, the free end of the elastic member 23 is pressed to push the support body 20 so that the slide bar 21 enters the cavity of the storage tube 22. The free end of the elastic member 23 is released, the elastic member 23 restores its deformation, and the contact block 24 contacts the top surface of the storage tube 22 to lock the position of the slide bar 21.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
