A limiting component is installed on the inner side of the storage rack, and the bottom end of the storage tube can be inserted into the limiting component. The storage mechanism also includes a limiting sleeve, which is detachably installed on the outer wall of the storage tube. Through the storage box and storage mechanism, the limiting component and the limiting sleeve cooperate to fix the storage tube on the storage rack. The elastic support block and the limiting component can improve the shock absorption performance of the device, and the limiting sleeve can improve the stability of the connection between the storage rack and the storage tube, effectively protecting the storage tube and preventing damage during transportation. This facilitates water quality testing. The limiting strip and the locking block can improve the stability between the storage rack and the storage box, and the handle and the fixing block facilitate the removal of the storage rack.

[0004] In the aforementioned prior art, test tubes containing water samples can be placed inside a limiting device and a limiting sleeve. However, this device has a poor sealing effect on the test tubes containing water samples. If shaking or bumping occurs during transportation, the water sample stored in the test tube is prone to leakage, resulting in sample loss and affecting the water quality testing. Therefore, a water sample storage device for water quality testing is needed to meet people's needs. Utility Model Content

[0008] Preferably, the sealing structure includes a positioning cover plate, which is movably installed in a positioning groove. A rubber sleeve is installed inside the positioning cover plate and is movably fitted onto the water sample storage tube.

[0009] Preferably, the extrusion structure includes a beveled extrusion ring, which is installed at one end of a connecting rod. Both the connecting rod and the beveled extrusion ring are slidably installed inside the positioning cover plate. A rubber ring is fixedly fitted on the rubber sleeve, and the beveled extrusion ring corresponds to the rubber ring.

An L-shaped clamping plate is rotatably sleeved on the fixed shaft, and a slot is opened on the inner wall of the positioning groove. The L-shaped clamping plate corresponds to the slot.

[0012] Preferably, one end of the torsion spring is installed on the inner wall of the L-shaped plate, and the other end of the torsion spring is installed on the fixed shaft, with the torsion spring sleeved on the fixed shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, after the water sample storage tube is filled with water quality test samples, its bottom end can be placed in the rubber pad, and then the positioning cover plate can be inserted into the positioning groove and the rubber sleeve inside the positioning cover plate can be fitted onto the opening of the water sample storage tube to seal the opening of the water sample storage tube, preventing the sample in the water sample storage tube from flowing out due to shaking during transportation. After the sealing is completed, the L-shaped card plate can be inserted into the card groove by rotating the screw, which can prevent the positioning cover plate from falling out of the positioning groove, thereby restricting the position of the water sample storage tube and improving the stability of the water sample storage tube.

Detailed Implementation

[0022] 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.

[0023] Example 1: Please refer to Figures 1-5 This utility model provides a technical solution: a water sample storage device for water quality testing, including a storage box 100; a fixing plate 200 is installed inside the storage box 100, and a plurality of positioning structures are connected to one side of the fixing plate 200. A plurality of positioning grooves 300 are opened on the fixing plate 200, and a sealing structure is connected inside the positioning grooves 300. A connecting rod 400 is connected to the sealing structure, and a squeezing structure is connected to the connecting rod 400. A squeezing rod 500 is connected to the squeezing structure, and a limiting structure is connected to the squeezing rod 500. In use, the water sample storage tube can be placed on the positioning structure, and then the opening of the water sample storage tube is sealed by the sealing structure. The squeezing structure can squeeze the sealing structure, making the sealing structure fit more tightly with the water sample storage tube, while the limiting structure can prevent the sealing structure from loosening from the water sample storage tube, thus achieving the sealing and fixing of the water sample storage tube.

[0024] Furthermore, the positioning structure includes a base 201, which is installed on one side of the fixing plate 200. A rubber pad 202 is installed inside the base 201, and a water sample storage tube 203 is movably sleeved on the rubber pad 202. When storing the water sample storage tube 203, the bottom end of the water sample storage tube 203 can be inserted into the rubber pad 202 on the base 201 to position the water sample storage tube 203.

[0025] Furthermore, the sealing structure includes a positioning cover plate 301, which is movably installed in the positioning groove 300. A rubber sleeve 302 is installed inside the positioning cover plate 301. The rubber sleeve 302 is movably fitted onto the water sample storage tube 203. The positioning cover plate 301 is aligned with the positioning groove 300 and inserted. At the same time, the positioning cover plate 301 drives the rubber sleeve 302 to fit over the opening of the water sample storage tube 203, thereby sealing the opening end of the water sample storage tube 203 with the rubber sleeve 302.

[0026] Furthermore, the extrusion structure includes a beveled extrusion ring 401, which is installed at one end of a connecting rod 400. Both the connecting rod 400 and the beveled extrusion ring 401 are slidably installed inside the positioning cover plate 301. A rubber ring 402 is fixedly fitted on the rubber sleeve 302, with the beveled extrusion ring 401 corresponding to the rubber ring 402. A linkage plate 403 is installed at one end of the connecting rod 400, and a screw 404 is installed in the internal thread of the linkage plate 403. The screw 404 is rotatably installed on the positioning cover plate 301. Rotating the screw 404 can drive the linkage plate 403 to move, so that the linkage plate 403 drives the beveled extrusion ring 401 to extrude the rubber ring 402 through the connecting rod 400. The rubber ring 402 will deform under the extrusion and press against the rubber sleeve 302, so that the rubber sleeve 302 can fit tightly against the outer surface of the water sample storage tube 203, improving the sealing effect.

[0027] Furthermore, the linkage plate 403 has a threaded hole 405 inside, and the screw 404 is threadedly installed in the threaded hole 405. When the screw 404 rotates, it can drive the linkage plate 403 to move toward the positioning cover plate 301 through the threaded engagement with the threaded hole 405.

[0028] Example 2: As Figures 2-5To restrict the position of the positioning cover 301 and prevent it from becoming detached from the water sample storage tube 203, a limiting structure is arranged on the squeezing rod 500. This limiting structure includes a fixed shaft 501, which is installed inside the positioning cover 301 and contacts one end of the squeezing rod 500. The squeezing rod 500 is installed on the bottom side of the linkage plate 403. An L-shaped retaining plate 502 is rotatably sleeved on the fixed shaft 501. A retaining groove 503 is formed on the inner wall of the positioning groove 300. Corresponding to the slot 503, one end of the torsion spring 504 is installed on the inner wall of the L-shaped plate 502, and the other end of the torsion spring 504 is installed on the fixed shaft 501. The torsion spring 504 is sleeved on the fixed shaft 501. During the descent, the linkage plate 403 will drive the pressing rod 500 to press against the L-shaped plate 502. When the L-shaped plate 502 is pressed, it will rotate, so that one end of the L-shaped plate 502 enters the slot 503, preventing the positioning cover plate 301 from falling out of the positioning groove 300. The remaining features are the same as in embodiment 1.

[0029] The working principle is as follows: When storing the water sample storage tube 203, first insert the bottom end of the water sample storage tube 203 into the rubber pad 202 on the base 201, then align the positioning cover plate 301 with the positioning groove 300 and insert it. At the same time, the positioning cover plate 301 causes the rubber sleeve 302 to be placed over the opening of the water sample storage tube 203, thus sealing the opening of the water sample storage tube 203 with the rubber sleeve 302. Figure Four In this state, the screw 404 can be rotated. When the screw 404 rotates, it can drive the linkage plate 403 to move towards the positioning cover plate 301 through the threaded engagement with the threaded hole 405. This causes the linkage plate 403 to drive the connecting rod 400 to move, and the connecting rod 400 to drive the inclined extrusion ring 401 to slide inside the positioning cover plate 301. The continuously sliding inclined extrusion ring 401 will cause its inclined surface to press against the rubber ring 402. The rubber ring 402 will deform under the pressure and press against the rubber sleeve 302, so that the rubber sleeve 302 can fit tightly against the outer surface of the water sample storage tube 203, improving the sealing effect. At the same time, during the descent, the linkage plate 403 will drive the extrusion rod 500 to press against the L-shaped clamping plate 502. The L-shaped clamping plate 502 is compressed. The rotating screw 404 on the fixed shaft 501 compresses the torsion spring 504, causing the rotating L-shaped clamping plate 502 to move one end into the clamping groove 503 until one side of the L-shaped clamping plate 502 is in contact with the inner top wall of the clamping groove 503. This achieves the limiting operation of the positioning cover plate 301, preventing the positioning cover plate 301 from falling out of the positioning groove 300. When it is necessary to open the positioning cover plate 301, simply rotate the screw 404 in the opposite direction to disengage the inclined extrusion ring 401 from the extrusion of the rubber ring 402. At the same time, the extrusion rod 500 will disengage from the extrusion of the L-shaped clamping plate 502, and the compressed torsion spring 504 will be released, causing the L-shaped clamping plate 502 to flip and reset, thus releasing the L-shaped clamping plate 502 from the clamping groove 503 so that the positioning cover plate 301 can be pulled out.
