[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 - Figure 3This utility model provides an embodiment of a water quality testing sample storage box, including a receiving box 1 for holding sample containers. The upper surface of the receiving box 1 is provided with a clamping assembly 2 for stably holding sample containers of different sizes and preventing them from shaking. The clamping assembly 2 includes a rotating disk 21 for driving a guide rod 23 to move back and forth by rotating itself. The lower surface of the rotating disk 21 is rotatably connected to the upper surface of the receiving box 1. The inner wall of the rotating disk 21 is provided with a groove 22 for pushing the guide rod 23 by its own shape. The inner wall of the groove 22 is slidably connected to the guide rod 23 for transmitting the force of the rotating disk 21 to a connecting rod 25. The lower surface of the guide rod 23 is fixedly connected to a connecting rod 25 for connecting the guide rod 23, a fixing block 26, and a support spring 24 together. The rear surface of the 5 is fixedly connected to a fixing block 26, which is made of rubber and is used to adhere to the surface of the sample container to fix the sample container. The front surface of the connecting rod 25 is fixedly connected to a support spring 24, which is used to continuously support the connecting rod 25 and make the sample container stably clamped by the fixing block 26. The front surface of the support spring 24 is fixedly connected to the inner wall of the receiving box 1. The outer wall of the connecting rod 25 is slidably connected to the inner wall of the receiving box 1. The inner wall of the receiving box 1 is provided with a second sliding groove 27 for supporting the back and forth movement of the guide rod 23. The guide rod 23 is slidably connected to the inner wall of the second sliding groove 27. The front surface of the receiving box 1 is provided with an unlocking component 3 for easy unlocking of the receiving box 1 by the operator. The upper surface of the receiving box 1 is rotatably connected to a box cover 4. The front surface of the box cover 4 is provided with a locking component 6 for locking the receiving box 1.

[0030] Reference Figure 1 - Figure 3 The slide 22 is designed in an arc shape so that the rotating disk 21 can drive the guide rod 23 to move when it rotates. The front surface of the housing 1 is fixedly connected to a handle 5 for easy gripping by the operator. The fixing block 26 is designed in a U shape so that the sample container is clamped at multiple points, which is better than the three-point clamping. It maintains six lines of contact. The locking component 6 includes a fixing plate 61 for supporting the reset spring 62. The rear surface of the fixing plate 61 is fixedly connected to the front surface of the lid 4. The inner wall of the fixing plate 61 is fixedly connected to the reset spring 62 for continuously supporting the insert block 63. The upper end of the reset spring 62 is fixedly connected to the insert block 63. The outer wall of the insert block 63 is slidably connected to the inner wall of the fixing plate 61.

[0031] Reference Figure 1 - Figure 3The upper surface of the insert 63 is provided with a slope near the front end, so that when the insert 63 contacts the outer wall of the receiving box 1, it can retract into the inner wall of the fixing plate 61 without any operation, and push out the button 32 under the action of the return spring 62 after movement. The unlocking component 3 includes a hollow base 31 for supporting the sliding of the button 32. The rear surface of the hollow base 31 is fixedly connected to the front surface of the receiving box 1. The inner wall of the hollow base 31 is slidably connected to a button 32 for pressing the button 32 to push the insert 63 into the inner wall of the fixing plate 61 when locked, so as to realize the unlocking operation. The front surface of the receiving box 1 is provided with a slot 33 for accommodating the fixing plate 61. The outer wall of the fixing plate 61 is inserted into the inner wall of the slot 33, and the outer wall of the insert 63 is inserted into the inner wall of the hollow base 31.

[0032] Working principle: First, rotate the rotating disk 21. The rotation of the rotating disk 21 drives the guide rod 23 to move backward. The movement of the guide rod 23 drives the connecting rod 25 to move. At this time, the support spring 24 undergoes elastic deformation. When the rotating disk 21 drives the guide rod 23 to fully open, press down on the rotating disk 21 and place the water quality test sample container at the center of the multiple sets of connecting rods 25. Gradually reduce the pressure on the rotating disk 21. Under the action of the support spring 24, the connecting rod 25 drives the guide rod 23 to move in the opposite direction and drives the rotating disk 21 to rotate, making the fixing block 26 tightly closed. The device fits snugly against the sample container, securing it securely. It can also hold large or small sample containers stably. When locking the lid 4, the fixing plate 61 gradually inserts into the slot 33. The insert 63 has a slope, so that when the insert 63 contacts the slot 33, it gradually retracts into the inner wall of the fixing plate 61. When fully closed, the return spring 62 inside the fixing plate 61 pushes the insert 63 out. The insert 63 drives the button 32 to move forward, thus securing the device. To unlock, simply press the button 32 simultaneously.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
