Description

Technical Field

[0001] This utility model belongs to the field of sample preservation technology, and specifically relates to a device for preserving test samples. Background Technology

[0002] Water quality testing is the process of analyzing the physical, chemical, and biological characteristics of water bodies to assess whether the water quality meets relevant standards. Water quality testing is a crucial part of environmental protection, as it can identify the root causes of water pollution and fundamentally improve water quality. Common water quality testing methods include spectroscopic methods, electrochemical methods, and biosensor methods. When testing water quality, it is necessary to use sample preservation devices to preserve the water samples.

[0003] Existing sample preservation devices are often a single, integrated box structure that typically lacks folding functionality. When a large number of samples are collected, multiple preservation boxes are often required to meet the usage needs. However, multiple preservation boxes are inconvenient to move and carry, and therefore require improvement. Utility Model Content

[0004] The purpose of this invention is to provide a sample storage device. When in use, the second and third boxes are stored inside the first box, thus requiring less space for transport and storage, and making it easier for staff to carry. When it is necessary to store a large number of samples at the same time, the second box can be unfolded for sample storage, making it more versatile and eliminating the need to carry multiple storage boxes at the same time.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A sample preservation device for testing, comprising

[0007] The first box has an opening on the front side and vertical grooves on the inner walls of both the left and right sides.

[0008] The second housing is slidably assembled inside the first housing, and through slots matching the positions of the vertical slots are provided on both the left and right sides of the second housing.

[0009] There are two sliders, which are respectively mounted up and down inside two through slots. The two sliders are close to each other and are fixedly installed on one side. A closed door is hinged to the top of the third box. A locking mechanism is provided between the third box and the first box.

[0010] As a preferred technical solution, the bottom sides of the interior of both the second and third boxes are fixedly installed with plug-in cotton, and the tops of the two plug-in cotton are provided with several plug-in holes.

[0011] As a preferred technical solution, the locking mechanism includes two mounting barrels. The upper and lower parts of the left side of the housing are respectively provided with a first through hole and a second through hole. The left side of the second housing is provided with a third through hole that matches the position of the second through hole. The lower left side of the third housing is provided with a fourth through hole that matches the position of the third through hole.

[0012] The two mounting barrels are respectively fixedly installed on the upper and lower left sides of the first housing. The two mounting barrels are respectively matched with the positions of the first through hole and the second through hole. Both mounting barrels are equipped with plug-in components inside.

[0013] As a preferred technical solution, both of the plug-in components include locking rods. The two locking rods are slidably assembled inside the two mounting barrels. One end of each locking rod passes through a first through hole and a second through hole, respectively. A spring is fixedly installed on the end of each locking rod away from the first housing. One end of each spring is fixedly connected to the inner wall of the two mounting barrels, respectively. A pull rod is fixedly installed on the end of each locking rod away from the first housing.

Detailed Implementation

[0026] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1-7 As shown, this utility model provides a sample preservation device, comprising:

[0028] The first box 1 has an opening 11 on the front side and vertical grooves 12 on the inner walls of both the left and right sides.

[0029] The second box 2 is slidably assembled inside the first box 1. The second box 2 has through slots 21 on both the left and right sides that match the position of the vertical slot 12.

[0030] There are two sliders 3, which slide up and down and are assembled inside the two through slots 21 respectively. The two sliders 3 are close to each other and are fixedly installed on one side. The top of the third box 31 is hinged and fitted with a closed door 32. A locking mechanism 33 is provided between the third box 31 and the first box 1. The locking mechanism 33 includes two mounting barrels 46. The upper and lower left sides of the box 1 are respectively provided with a first through hole 41 and a second through hole 42. The left side of the second box 2 is provided with a third through hole 43 that matches the position of the second through hole 42. The lower left side of the third box 31 is provided with a fourth through hole 45 that matches the position of the third through hole 43.

[0031] Two mounting barrels 46 are fixedly installed on the upper and lower left sides of the first housing 1, respectively. The two mounting barrels 46 are respectively matched with the positions of the first through hole 41 and the second through hole 42. Both mounting barrels 46 are equipped with plug-in components inside.

[0032] In the initial state, the two plug-in components are respectively inserted into the first through hole 41 and the second through hole 42. After the lower plug-in component enters the second through hole 42, it will sequentially enter the third through hole 43 and the fourth through hole 45. In this state, the positions of the second box 2 and the third box 31 are locked. The second box 2 cannot slide outward, and the third box 31 cannot slide upward. The staff can directly use the carrying strap 51 to carry the first box 1 for position transfer or transportation. The operation is simple and convenient, and it occupies a small volume. When the sample to be preserved is small, the closed door 32 can be opened directly. The closed door 32 and the third box 31 are directly equipped with a door lock. After opening, the staff will sequentially insert the water sample into the several plug-in holes 35 opened by the plug-in cotton 34 inside the third box 31. Then close the closed door 32 and lock it.

[0033] When there are many samples to be preserved, the staff can disconnect the two plug-in components. The second box 2 can slide forward out of the first box 1, and the third box 31 can slide upward completely out of the second box 2. The staff should first control the third box 31 to slide completely upward out of the second box 2 and use the upper plug-in component to lock the connection, so that the third box 31 will not fall downward. Then, control the second box 2 to slide forward. The staff can then insert the samples one by one into the plug-in cotton 34 inside the second box 2. After installation, push the second box 2 back into its original position and use the lower plug-in component to lock it. In this way, the second box 2 can be unfolded and used for different numbers of samples to be preserved, which is highly applicable.

[0034] Both plug-in components include locking rods 47, which are slidably fitted inside the two mounting barrels 46. One end of each locking rod 47 passes through the first through hole 41 and the second through hole 42, respectively. A spring 48 is fixedly installed on the end of each locking rod 47 away from the first housing 1. One end of each spring 48 is fixedly connected to the inner wall of the two mounting barrels 46. A pull rod 49 is fixedly installed on the end of each locking rod 47 away from the first housing 1. One end of each pull rod 49 extends out of the mounting barrel 46 and is fixedly connected to a flexible strip 50.

[0035] In the initial state, under the action of the two springs 48, the two locking rods 47 are pushed to move, and the lower locking rod 47 enters the third through hole 43 and the fourth through hole 45, completing the locking of the third box 31. Then, the second box 2 and the third box 31 cannot move. The third box 31 is stored inside the second box 2, reducing the overall volume and making it easier to handle, store and transport. Due to the setting of the flexible belt 50, the staff can pull one of the pull rods 49 in sequence or pull both pull rods 49 at the same time to complete the synchronous unlocking according to the needs of use. After unlocking, the third box 31 can be pushed up and down. The third box 31 slides out of the second box 2 completely, and its fourth through hole 45 will be aligned with the upper locking rod 47. The staff can use the upper locking rod 47 to lock the position of the third box 31. After the sample is loaded into the second box 2, it is pushed back to the original position, and its third through hole 43 will be aligned with the lower locking rod 47. The staff can use the lower locking rod 47 to lock the position. The operation is simple and convenient.

[0036] Both the second box 2 and the third box 31 have insertion cotton 34 fixedly installed on their bottom sides. Several insertion holes 35 are arranged on the top of each insertion cotton 34. The insertion holes 35 are used for inserting the sample collection bottle. After insertion, the insertion holes 35 have a wrapping force, making them more stable.

[0037] The first box 1 is fixedly installed with shoulder straps 51 on both the left and right sides; the shoulder straps 51 make it easy for staff to move the first box 1.

[0038] The device is used as follows:

[0039] When in use, depending on the number of samples to be stored, when the number of samples is small, after the first box 1 is moved to the designated position, the sealing door 32 can be opened to directly insert the sample bottles into several insertion holes 35 for fixation. The second box 2 and the third box 31 are not in the unfolded state, which saves more space during relocation and transportation and is convenient to use. When more samples need to be stored, the staff pulls the two locking rods 47 at the same time to unlock, pushes the third box 31 upward first, and locks it with the upper locking rod 47. Then, after the second box 2 is pulled out and the samples are placed, the second box 2 is pushed into the first box 1 and locked with the lower locking rod 47. This can be used to store a larger number of samples. The operation is simple and convenient. The whole structure is integrated, which also facilitates transportation.

[0040] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
