Abstract
Description
Technical Field
[0001] This utility model relates to the field of water quality testing equipment technology, and in particular to a water quality testing sample preservation mechanism. Background Technology
[0002] When collecting water samples from rivers or streams outdoors, the water quality is affected by various factors such as seasonal changes, rainfall, and human activities. A single sampling is insufficient to fully reflect the true water quality, so multiple samplings are usually required. The collected samples are mostly collected in test tubes and stored in a box. When testing, they are taken out together and used. As a result, there are many samples in the box. Also, for the same batch of water samples, it is sometimes necessary to repeat the test and take the average data to reduce experimental errors. When many water samples are stored in the same box, it is easy to cause confusion or omission during testing. In order to avoid forgetting which samples have been tested and how many times they have been tested, the conventional method is to label the surface of the test tubes. However, because there are many test tubes and they are densely distributed, the labels can be obscured by adjacent test tubes, making it difficult to identify samples that have been tested and making it difficult to quickly find the samples to be tested, resulting in low testing efficiency. Utility Model Content
[0003] In view of this, the purpose of this utility model is to propose a water quality test sample preservation mechanism to solve the technical problem that existing water quality sample preservation boxes are prone to repeated testing or omission of the same sample during testing due to the large number of samples.
[0004] To achieve the above objectives, this utility model provides a water quality testing sample preservation mechanism, comprising:
[0005] Box body;
[0006] At least one support plate disposed in the box body for supporting the water sample storage container;
[0007] The port has two sleeves with guide rail surfaces. The two sleeves are fixedly connected and a guide gap is formed between their guide rail surfaces. The sleeves are fixedly connected to the support plate and elastically connected to the box.
[0008] A first marking portion is provided at the upper end of the sleeve;
[0009] A movable shaft with a second marking section at the top is fitted in a sleeve, and its lower end can extend out of the sleeve and contact the bottom of the box. The movable shaft can be raised and lowered in the sleeve by placing and removing the water sample storage container from the support plate.
[0010] A drive member is provided on the surface of the movable shaft and can move synchronously with it. The drive member can slide along the guide gap to convert the lifting motion of the movable shaft into rotational motion, so that the second marking part rotates relative to the first marking part to indicate the number of pick-up and drop-off.
[0011] As a preferred embodiment of this utility model, the first marking part is a pointer set at the top of the sleeve, and the second marking part is a digital wheel set at the top of the movable shaft. The number on the digital wheel corresponds to the number of times the water sample storage container on the support plate is picked up and put down.
[0012] As a preferred embodiment of this utility model, the sleeve has an observation port at its top, and a transparent plate is provided at the observation port.
[0013] As a preferred embodiment of this invention, a connecting rod for connecting the two sleeves is provided between them.
[0014] As a preferred embodiment of this utility model, a first limiting member is provided at the lower end of the sleeve, a second limiting member is provided at the bottom of the box, and a spring is provided between the first limiting member and the second limiting member to connect the two.
[0015] As a preferred embodiment of this utility model, a stop bar is provided at the bottom of the movable shaft, and the radius of the stop bar is smaller than the radius of the movable shaft.
[0016] As a preferred technical solution of this utility model, the interior of the box is provided with a plurality of first partitions and second partitions. The first partitions and second partitions can cooperate with each other to divide the interior of the box into a plurality of independent chambers, and a support plate is provided in each independent chamber.
[0017] As a preferred technical solution of this utility model, the support plate is provided with positioning holes for limiting the water sample storage container.
[0018] The beneficial effects of this utility model are as follows: This utility model sets up a sleeve with a guide rail surface, so that the sleeve is fixedly connected to the support plate, and a movable shaft is slidably arranged in the sleeve. By setting a driving component on the surface of the movable shaft, when the water sample storage container is put into and taken out of the support plate, the driving component can work with the guide rail surface to drive the movable shaft to rotate. The number of times the container is put into and taken out is recorded by the marking part on the surface of the movable shaft and the sleeve, so as to remind the testing personnel to prevent missed detection.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0027] like Figure 3 and Figure 4As shown, a water quality testing sample preservation mechanism includes: a box body 1; at least one support plate 5 disposed in the box body 1 for supporting a water sample storage container 4; two sleeves 7 with guide rail surfaces 8 at their ends, the two sleeves 7 being fixedly connected and forming a guide gap between their guide rail surfaces 8, the sleeves 7 being fixedly connected to the support plate 5 and elastically connected in the box body 1; a first marking part 14 disposed at the upper end of the sleeves 7; a movable shaft 10 with a second marking part 13 disposed at its top end, the movable shaft 10 being sleeved in the sleeves 7 and its lower end being able to extend out of the sleeves 7 and contact the bottom of the box body 1, the movable shaft 10 being able to move up and down in the sleeves 7 by placing and removing the water sample storage container 4 from the support plate 5; a driving member 11 disposed on the surface of the movable shaft 10 and able to move synchronously with it, the driving member 11 being able to slide along the guide gap to convert the lifting motion of the movable shaft 10 into rotational motion, so that the second marking part 13 rotates relative to the first marking part 14 to indicate the number of times it is picked up and placed;
[0028] The above technical solution can automatically mark water samples that have been tested and record the number of tests for the same water sample. In use, the water sample storage container 4 containing the water sample is placed on the support plate 5. The weight of the water sample storage container 4 will cause the support plate 5 to overcome the elastic force and move downward, thereby causing the support plate 5 to drive the sleeve 7 to move downward. This will cause the movable shaft 10 inside the sleeve 7 to move downward synchronously. When the bottom end of the movable shaft 10 touches the bottom end of the box 1, as the sleeve 7 continues to move downward, the lower end of the movable shaft 10 retracts into the sleeve 7 until it can no longer move downward. The driving component 11 on the surface of the movable shaft 10 slides along the guide rail surface 8 on the surface of the sleeve 7, thereby driving the movable shaft 10 to rotate horizontally. The second marking part 13 at the upper end of the movable shaft 10 will rotate relative to the first marking part 14 at the upper end of the sleeve 7. The number corresponding to the second marking part 13 and the first marking part 14 at this time is 0, indicating that the water sample storage container 4 has not been taken out for testing.
[0029] When it is necessary to test the water sample storage container 4, the water sample storage container 4 is taken out. As the water sample storage container 4 leaves the support plate 5, the support plate 5 automatically resets under the action of elasticity. Under its own gravity, the bottom end of the movable shaft 10 gradually extends out of the sleeve 7. The driving component 11 slides along the guide rail surface 8, thereby driving the movable shaft 10 to continue to rotate. The second marking part 13 and the first marking part 14 correspond to 0 to 1 at this time.
[0030] After the test is completed, the water sample storage container 4 is placed back on the support plate 5. The weight of the water sample storage container 4 will cause the support plate 5 to move down against the elastic force. The second marking part 13 at the upper end of the movable shaft 10 will rotate relative to the first marking part 14 at the upper end of the sleeve 7. The number corresponding to the second marking part 13 and the first marking part 14 at this time is 1, thereby indicating to the tester that the sample has been tested once, preventing missed detection.
[0031] like Figure 4As shown, in this embodiment, the first marking part 14 is a pointer set at the top of the sleeve 7, and the second marking part 13 is a digital wheel set at the top of the movable shaft 10. The number on the digital wheel corresponds to the number of times the water sample storage container 4 on the support plate 5 is taken out and put in. The sleeve 7 has an observation port 9 at its top, and a transparent plate is provided at the observation port 9.
[0032] The above technical solution enables the use of a circular digital wheel on the movable shaft 10, which, in conjunction with the pointer at the top of the sleeve 7, indicates the number of tests.
[0033] like Figure 3 and Figure 4 As shown, in this embodiment, a connecting rod 18 for connecting the two sleeves 7 is provided between them;
[0034] The above technical solution can connect the sleeves 7, ensuring that the drive component 11 on the movable shaft 10 will not detach from the guide surface 8 between the sleeves 7.
[0035] like Figure 3 and Figure 4 As shown, in this embodiment, a first limiting member 15 is provided at the lower end of the sleeve 7, a second limiting member 16 is provided at the bottom of the box body 1, and a spring 17 for connecting the first limiting member 15 and the second limiting member 16 is provided between the two.
[0036] The above technical solution ensures that the support plate 5 can automatically reset after the water sample storage container 4 is removed from the support plate 5.
[0037] like Figure 3 and Figure 4 As shown, in this embodiment, a contact rod 12 is provided at the bottom of the movable shaft 10, and the radius of the contact rod 12 is smaller than the radius of the movable shaft 10.
[0038] The above technical solution can reduce the rotational friction of the movable shaft 10. Since the radius of the abutment rod 12 is small, the contact surface between the abutment rod 12 and the bottom of the box 1 is small, which makes the rotational resistance smaller and facilitates the rotation of the movable shaft 10.
[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the interior of the box 1 is provided with a plurality of first partitions 2 and second partitions 3. The first partitions 2 and second partitions 3 can cooperate with each other to divide the interior of the box 1 into a plurality of independent chambers, and a support plate 5 is provided in each independent chamber.
[0040] The above technical solution allows for convenient and neat placement of samples inside the box 1. If necessary, the independent chambers can also be labeled to correspond to the corresponding water sample storage container 4 to prevent misplacement.
[0041] like Figure 3 As shown, in this embodiment, the support plate 5 is provided with a positioning hole 6 for limiting the water sample storage container 4;
[0042] The above technical solution can easily and stably place the water sample storage container 4 on the support plate 5, preventing the water sample storage container 4 from falling.
[0043] Working principle: When in use, the water sample storage container 4 containing the water sample is placed into the positioning hole 6 on the support plate 5. The weight of the water sample storage container 4 will cause the support plate 5 to overcome the elastic force of the spring 17 and move downward, thereby causing the support plate 5 to drive the sleeve 7 to move downward. In turn, the sleeve 7 drives the movable shaft 10 inside to move downward synchronously. When the abutment rod 12 at the bottom of the movable shaft 10 touches the bottom of the box body 1, as the sleeve 7 continues to move downward, the lower end of the movable shaft 10 retracts into the sleeve 7 until it can no longer move downward. The driving component 11 on the surface of the movable shaft 10 slides along the guide rail surface 8 on the surface of the sleeve 7, thereby driving the movable shaft 10 to rotate horizontally. The second marking part 13 at the upper end of the movable shaft 10 will rotate relative to the first marking part 14 at the upper end of the sleeve 7. The number corresponding to the second marking part 13 and the first marking part 14 at this time is 0, indicating that the water sample storage container 4 has not been taken out for testing.
[0044] When it is necessary to test the water sample storage container 4, the water sample storage container 4 is taken out. As the water sample storage container 4 leaves the support plate 5, the support plate 5 automatically resets under the action of elasticity. Under its own gravity, the abutment rod 12 at the bottom of the movable shaft 10 gradually extends out of the sleeve 7. The driving component 11 slides along the guide rail surface 8, thereby driving the movable shaft 10 to continue to rotate. The second marking part 13 and the first marking part 14 correspond to 0 to 1 at this time.
[0045] After the test is completed, the water sample storage container 4 is placed back on the support plate 5. The weight of the water sample storage container 4 will cause the support plate 5 to move down against the elastic force. The second marking part 13 at the upper end of the movable shaft 10 will rotate relative to the first marking part 14 at the upper end of the sleeve 7. The number corresponding to the second marking part 13 and the first marking part 14 at this time is 1, thereby indicating to the tester that the sample has been tested once, preventing missed detection.

[0047] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
