Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to a water sample storage device for testing. Background Technology

[0002] Water quality testing refers to the systematic analysis and evaluation of physical, chemical, and biological indicators in water bodies to determine whether the water body meets the standards and requirements for a specific purpose. Water quality testing typically includes the detection of indicators such as suspended solids, dissolved solids, pH value, dissolved oxygen, organic matter, heavy metals, bacteria, and viruses in water.

[0003] After water samples are taken, they generally cannot be tested immediately and need to be transported to a designated testing institution. In order to ensure that the water samples do not change during storage, special storage devices are needed to store and protect the sample tubes containing the water samples. Some water samples also need to have reagents added during storage to ensure that the ions to be tested in the water samples do not precipitate and avoid affecting the laboratory test results.

[0004] Existing water sample storage devices have a designated area inside for storing the necessary reagents, and several holes are provided for storing water sample tubes. However, these devices lack clamping and securing for the reagents and water sample tubes, causing the tubes and reagent bottles to shake during transport. The shaking tubes may collide with each other and eventually be damaged, making them inconvenient to use. Utility Model Content

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example

[0024] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present utility model. This embodiment provides a water sample storage device for testing, including a box 1, an insulation layer 3 inside the box 1, a cover 2 hinged to the top of the box 1, a fixing sleeve 4 inside the box 1, an insertion hole inside the fixing sleeve 4, an adjustment component 5 inside the box 1, and a fixing component 6 inside the cover 2. Adjustment component 5 includes a rotating shaft 501 movably connected inside the housing 1. A transmission bevel gear 507 is fixedly installed on the outer surface of the rotating shaft 501. Two threaded rods 506 are movably connected inside the housing 1. One end of each threaded rod 506 is fixedly installed with a driven bevel gear 508 that meshes with the transmission bevel gear 507. A threaded sleeve 503 is meshed with the outer surface of the threaded rod 506. An L-shaped plate 505 is provided above the threaded sleeve 503.

[0025] Specifically, a worm gear 511 is fixedly installed on the outer surface of the rotating shaft 501, and a transmission rod 510 is movably connected inside the housing 1. A worm 509 that meshes with the worm gear 511 is fixedly installed on the outer surface of the transmission rod 510. The unidirectional transmission characteristic of the worm gear 511 and the worm 509 prevents the reagent bottle from squeezing the L-shaped plate 505 in the opposite direction, thus preventing the L-shaped plate 505 from becoming loose. The top of the transmission rod 510 passes through the upper surface of the housing 1 and is fixedly connected to an internal hexagonal nut. The internal hexagonal nut facilitates the rotation of the transmission rod 510.

[0026] Specifically, a groove is provided at the bottom of the inner cavity of the box 1. A threaded rod 506 is movably connected inside the groove. An insert plate 502 is fixedly installed inside the groove. A movable seat 504 is fixedly installed between the threaded sleeve 503 and the L-shaped plate 505. The movable seat 504 has an insertion port that mates with the insert plate 502. The movable seat 504 can mate with the inner wall of the groove. Through the mate between the insert plate 502 and the movable seat 504, the movement of the movable seat 504 is limited. The insertion port inside the movable seat 504 is close to the upper surface of the movable seat 504. As the reagent bottle placed on the upper surface of the insert plate 502 moves with the L-shaped plate 505, the movable seat 504 can be inserted under the reagent bottle and thus squeezed and fixed by the L-shaped plate 505.

[0027] Specifically, the outer surface of the L-shaped plate 505 is provided with several flexible strips. The flexible strips facilitate the L-shaped plate 505 to squeeze and fix the reagent bottle, avoiding damage to the reagent bottle caused by hard squeezing.

[0028] Furthermore, an internal hexagonal nut is fixedly installed on the top of the transmission rod 510. By rotating the internal hexagonal nut on the top of the transmission rod 510 with a tool, the rotation of the transmission rod 510 drives the worm gear 509 to rotate. Through the cooperation of the worm gear 509 and the worm wheel 511, the rotating shaft 501 is driven to rotate. When the rotating shaft 501 rotates, the driven bevel gear 508 is driven to rotate through the transmission bevel gear 507, so that the threaded rods 506 on both sides rotate synchronously. Through the rotation of the threaded rods 506, the threaded sleeve 503 is driven to move, which in turn drives the moving seat 504 to move. In turn, the moving seat 504 drives the L-shaped plate 505 to move along the oblique line in the rectangular cavity, thereby gradually approaching the reagent bottle and squeezing the reagent bottle to fix the reagent bottle in the rectangular cavity and prevent it from shaking. Example

[0029] Reference Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The fixing component 6 includes two elastic clamping plates 601 fixedly installed on the inner wall of the insertion hole of the fixing sleeve 4. A compression spring 603 is provided at the bottom of the insertion hole cavity. A top piece 602 is fixedly installed at the top of the compression spring 603. A pressure plate 607 is provided inside the cover 2. Four sliding blocks 610 are slidably connected to the upper surface of the pressure plate 607. A rotating rod 611 is hinged to the upper surface of the sliding block 610. A movable frame 612 is provided through the top of the rotating rod 611 through the cover 2. A pin is provided between the movable frame 612 and the rotating rod 611. The rotating rod 611 is hinged to the cover 2.

[0030] Specifically, a sub-hole is provided at the bottom of the inner cavity of the internal insertion hole of the fixed sleeve 4, and a limit rod 604 is fixedly installed on the lower surface of the top piece 602. The limit rod 604 and the sub-hole cooperate to stabilize the lifting of the top piece 602.

[0031] Specifically, a conical pressure plate 609 that mates with the internal insertion hole of the fixed sleeve 4 is fixedly installed on the lower surface of the pressure plate 607. A rectangular groove for placing sampling tools is opened inside the fixed sleeve 4. A rectangular cavity is reserved between the fixed sleeve 4 and the inner wall of the box 1. An extrusion plate 608 that mates with the rectangular groove and the rectangular cavity is fixedly connected to the lower surface of the pressure plate 607. The top of the insertion hole inside the fixed sleeve 4 is sealed and extruded by the conical pressure plate 609, and the rectangular groove and the rectangular cavity are sealed and extruded by the extrusion plate 608.

[0032] Specifically, the cover 2 has a rectangular through groove for the movement of the rotating rod 611. The rotating rod 611 is hinged to the inner wall of the rectangular through groove. The movable frame 612 has rectangular openings on both sides. The pin is fixedly installed inside the rectangular opening. The rotating rod 611 has a sliding through groove that cooperates with the pin. The upper surface of the pressure plate 607 has a limiting sliding groove that cooperates with the sliding block 610. The rectangular through groove facilitates rotation. The rotating rod 611 is hinged to the inner wall of the rectangular through groove, thus achieving the effect of a rotation fulcrum. When the movable frame 612 rises, it drives the pin to slide inside the sliding through groove of the rotating rod 611, thereby driving the rotating rod 611 to rotate. The top of the movable frame 612 is provided with a handle for lifting.

[0033] Specifically, a blind hole is provided on the upper surface of the pressure plate 607. Several tension springs 605 are fixedly installed between the top of the inner cavity of the cover 2 and the upper surface of the pressure plate 607. A limit block 606 is fixedly connected to the top of the inner cavity of the cover 2. The bottom end of the limit block 606 passes through the inside of the tension spring 605 and is inserted into the blind hole. When the rotating rod 611 rotates, it moves through the sliding block 610, which simultaneously drives the pressure plate 607 to press down, thereby driving the tension spring 605 to stretch high. When the pressure plate 607 is pressed down, the limit block 606 always remains inserted inside the blind hole. After the handle is released, the return action of the tension spring 605 realizes the reset of the handle and the pressure plate 607.

[0034] Furthermore, the pre-treated sampling tube is inserted into the insertion hole inside the fixing sleeve 4. During insertion, the elastic clamping plate 601 bends, thereby squeezing the sampling tube through the reset action of the elastic clamping plate 601, rotating and closing and locking the cover 2 and the box 1. Then, the handle on the top of the movable frame 612 is lifted, thereby driving the movable frame 612 to rise. The rise of the movable frame 612 drives the pin to move, thereby driving the rotating rod 611 to rotate through the cooperation of the pin with the sliding through groove inside the rotating rod 611. This causes the pressure plate 607 to move down, thereby causing the conical pressure plate 609 on the lower surface of the pressure plate 607 to squeeze the sampling tube in the insertion hole inside the fixing sleeve 4. The squeezing plate 608 squeezes and closes the rectangular groove inside the fixing sleeve 4 and the rectangular cavity reserved between the fixing groove and the box 1, finally fixing the sampling tube and reagent bottle, preventing the reagent bottle and sampling tube from shaking and being damaged during storage and transportation.

[0035] Working principle: When storing water samples to be tested, the water is collected into the sampling tube using a sampling tool. Then, reagents are added as needed. The pre-treated sampling tube is inserted into the insertion hole inside the fixing sleeve 4. During insertion, the elastic clamping plate 601 bends, and through the resetting action of the elastic clamping plate 601, the sampling tube is squeezed and fixed, preventing lateral movement within the insertion hole. The completed sampling device is then placed into the rectangular groove inside the fixing sleeve 4. After use... The reagent bottle is inserted into the rectangular cavity reserved between the fixing sleeve 4 and the box 1. Then, the internal hex nut at the top of the transmission rod 510 is rotated by a tool. The rotation of the transmission rod 510 drives the worm gear 509 to rotate. Through the cooperation of the worm gear 509 and the worm wheel 511, the rotating shaft 501 is driven to rotate. When the rotating shaft 501 rotates, the driven bevel gear 508 is driven to rotate through the transmission bevel gear 507, so that the threaded rods 506 on both sides rotate synchronously. Through the rotation of the threaded rods 506, the threaded sleeve is driven to rotate. The tube 503 moves, thereby driving the moving seat 504 to move via the threaded sleeve 503. The moving seat 504 then drives the L-shaped plate 505 to move along the oblique line within the rectangular cavity, gradually approaching the reagent bottle and squeezing it to fix the bottle within the rectangular cavity and prevent it from shaking. Then, the cap 2 and the box 1 are rotated to close and lock. Next, the handle at the top of the movable frame 612 is lifted, causing the movable frame 612 to rise. This rise then drives the pin shaft to move, thereby… The pin shaft engages with the sliding groove inside the rotating rod 611 to rotate the rod 611, thereby causing the pressure plate 607 to move downward. This causes the conical pressure plate 609 on the lower surface of the pressure plate 607 to squeeze the sampling tube inside the insertion hole of the fixing sleeve 4. The squeezing plate 608 squeezes and seals the rectangular groove inside the fixing sleeve 4 and the rectangular cavity reserved between the fixing groove and the box 1, thus fixing the sampling tube and reagent bottle and preventing the reagent bottle and sampling tube from shaking and being damaged during storage and transportation.
