[0003] However, at present, various test sites are often troubled by a series of problems such as imperfect equipment in on-site professional laboratories, or the lack of temporarily purchased test equipment and drugs, which hinder the progress of the tests and ultimately prolong the project cycle. At the same time, there are many inconveniences when conducting some experiments. For example, when conducting a coagulation sedimentation experiment, it is necessary to stir the sewage evenly. In the prior art, large-scale coagulation test stirring equipment is generally used and paddles are used for stirring. This method has a large stirring equipment that is not convenient for storage and transportation, and the operation is complex.

[0004] For another example, when conducting volumetric analysis experiments such as total hardness and chloride ions, the burette needs to be vertically clamped on the burette stand through a burette clamp, and the reagent is titrated into a conical flask using the burette, and then the flask is manually shaken while titrating to make the solution mix evenly. However, manual shaking of the flask not only increases labor, but also it is difficult to ensure uniform mixing of the solution by manual operation, and the test error is large.

[0005] Therefore, based on the experience and practice of being engaged in the relevant industry for many years, the inventor of the present invention proposes a portable test box to overcome the defects of the prior art. Summary of the Invention

[0037] For a clearer understanding of the technical features, objectives, and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0038] As Figures 1 to 3 shown, this embodiment provides a portable test box, which includes two pivotally connected first storage boxes 1 and second storage boxes 2. Both the first storage box 1 and the second storage box 2 are box-like structures with one end open, and the open ends of the two are arranged in an opposing and mating manner. The interior of the first storage box 1 has a first storage slot 11, and the interior of the second storage box 2 has a plurality of second storage slots 21. A partial area on the outer surface of the bottom of the first storage box 1 forms a physicochemical reaction area 12, in which a container bottle can be placed, and a magnetic rotor can be placed inside the container bottle. A motor and a permanent magnet are provided in the first storage slot 11. The output shaft of the motor is fixedly connected to the permanent magnet, and the permanent magnet is arranged facing the physicochemical reaction area 12.

[0039] Among them, the above physical and chemical reaction area 12 can be a plane. For the above magnetic rotor, it is generally a granular body composed of a magnet and a plastic layer wrapped on the outer wall of the magnet, which can rotate under the action of a magnetic field. Its specific structure is the prior art and will not be elaborated here. The first storage tank 11 is mainly used to store various devices, such as the above-mentioned motor and permanent magnet. The second storage tank 21 is mainly used to store different detection instruments and reagents, such as conical flasks, magnetic rotors, burettes, and various solvents. The conical flask can generally be used. Place the devices that are not often taken out during the experiment in the first storage tank 11, and place those that need to be taken out and used frequently in the second storage tank 21, which is more convenient for storage and use.

[0040] Generally, both the first storage box 1 and the second storage box 2 include a box structure with one end open, which is enclosed by a bottom surface and side surfaces around. The outer wall of the bottom surface of the first storage box 1 constitutes the outer surface of the bottom of the first storage box 1. The entire test box has a storage position and a working position. After the first storage box 1 and the second storage box 2 are unfolded relative to each other, the entire test box is in the working position, as Figure 1 shown. At this time, the bottom surface of the first storage box 1 and the bottom surface of the second storage box 2 are in the same plane and are butted to form a test tabletop, and detection tests can be performed on this test tabletop; when the experiment is over, fold the first storage box 1 and the second storage box 2 relative to each other, and the entire test box is in the storage position, as Figure 2 shown. At this time, the entire test box occupies less space and is more convenient for storage and carrying.

[0041] When the test box is in the working position, if it is needed to cooperate in the coagulation and sedimentation experiment, first place the conical flask in the physical and chemical reaction area 12, add relevant reagents into the conical flask, and put a magnetic rotor into the conical flask. Then start the motor, and the motor drives the permanent magnet to rotate and generate a rotating magnetic field. Under the action of the rotating magnetic field, the magnetic rotor in the conical flask will be driven to rotate, thus playing a role in stirring. It should be noted that during operation, the rotation speed of the magnetic rotor is relatively small, which will only drive the solution to rotate and will not cause the conical flask to shake.

[0042] Therefore, in the portable test box of this embodiment, various devices can be stored in the first storage tank 11, and the instruments and reagents for the measured items can be stored in the second storage tank 21, which can meet the detection needs of the project and constitute a highly integrated small laboratory. When in use, unfold the first storage box 1 and the second storage box 2 to serve as a test tabletop for the experiment, and the test requirements can be met without excessive engineering investment. After the experiment is over, fold the test box to facilitate storage and is more convenient to transport to other projects for use. It is simple and convenient, saves resources, and greatly improves work efficiency.

[0043] In addition, the test chamber has a physical and chemical reaction zone 12, which can be used to place container bottles. By driving a permanent magnet to rotate with a motor to generate a rotating magnetic field, the magnetic rotor in the container bottle can be driven to rotate, realizing uniform stirring of the solution, replacing a dedicated coagulation test stirring device. All the devices or instruments for realizing stirring are integrated in the test chamber, which is more convenient for storage and carrying and is also easy to operate. The entire test chamber has a simple structure and is easy to operate. It can complete tests without the need to equip a professional laboratory and is suitable for various complex on-site working environments. According to the types of instruments and reagents stored, it can meet the detection of conventional items such as chloride ions, total hardness, COD, total phosphorus, total nitrogen, and total iron on site, effectively improving the efficiency of water quality adjustment work.

[0044] In a specific implementation manner, in order to reduce operation errors during the analysis experiments of volumetric method items such as total hardness and chloride ions, as Figure 1 , Figure 4 and Figure 5 shown, an installation hole 13 is opened at the bottom of the first storage box 1 and near the physical and chemical reaction zone 12. A support rod 3 can be inserted and fixed in the installation hole 13. The part of the support rod 3 extending outside the first storage box 1 can fix a burette, and the burette is arranged facing the container bottle.

[0045] Among them, the above-mentioned installation hole 13 is opened on the bottom surface of the first storage box 1. During use, first insert and fix the support rod 3 in the installation hole 13, and place the support rod 3 perpendicular to the bottom surface of the first storage box 1. Then clamp the burette on the support rod 3 through a burette clamp. The burette is placed perpendicular to the bottom surface of the first storage box 1 and the liquid dropping port of the burette faces the container bottle. Then add relevant reagents into the container bottle, put a magnetic rotor into the container bottle, start the motor, the motor drives the permanent magnet to rotate and generate a rotating magnetic field. Under the action of the rotating magnetic field, the magnetic rotor in the container bottle will be driven to rotate, thereby playing a role in stirring and realizing the experimental process of titration while stirring. This process replaces the work of manually shaking the bottle, making the reaction more uniform and reducing the error of manual operation. After the test, the support rod 3, burette, burette clamp, and container bottle can be stored in the second storage groove 21, which is more convenient.

[0046] To facilitate the installation and fixation of the support rod 3, as Figure 4 and Figure 5 shown, an external thread 31 is provided on the outer wall of one end of the support rod 3. The installation hole 13 is an internal thread hole. One end of the support rod 3 is inserted into the installation hole 13 and is threadedly connected to the installation hole 13. The inner surface of the bottom of the first storage box 1 (i.e., the inner wall of the bottom surface of the first storage box 1) is threadedly fastened to the support rod 3 through a nut 32.

[0047] Furthermore, in order to facilitate the use of this test bench to cooperate with the analysis experiments of photometric method items such as total nitrogen, ammonia nitrogen, total phosphorus, and total iron, asFigure 1 and Figure 6 As shown in Figure 6 , on another part of the outer surface of the bottom of the first storage box 1, an installation groove 14 is formed, and the installation groove 14 constitutes a colorimetric cell. A colorimetric cuvette is detachably fixed in the colorimetric cell. An ultraviolet-visible light source is also provided in the first storage tank 11. A through hole 141 is opened on one of the cell walls of the colorimetric cell. The through hole 141 is arranged opposite to the colorimetric cuvette, and the end of the ultraviolet-visible light source is inserted into the through hole 141. A light-shielding cover can be placed at the notch of the installation groove 14.

[0048] Specifically, the above-mentioned installation groove 14 is formed on the outer wall of the bottom surface of the first storage box 1. The colorimetric cuvette is a transparent glass container. The ultraviolet-visible light source is placed parallel to the bottom surface of the first storage box 1, and the end is inserted into the through hole 141, so as to be able to face the colorimetric cuvette directly, so that ultraviolet light can pass through the glass material of the colorimetric cuvette and irradiate on the reagent contained in the colorimetric cuvette. To facilitate the fixing of the colorimetric cuvette in the colorimetric cell, as Figure 6 shown in Figure 6 , generally a fixing block 142 is fixed in the colorimetric cell. The fixing block 142 has a plugging groove 1421, and the colorimetric cuvette can be inserted into the plugging groove 1421. Of course, other structures can also be used for the fixing of the colorimetric cuvette. This embodiment is only for illustration.

[0049] When in use, when wanting to detect the concentration of a sample to be measured, the sample to be measured can be first added into the colorimetric cuvette, and then the colorimetric cuvette is fixed in the colorimetric cell. The wavelength of the ultraviolet-visible light source is adjusted to the required value. After powering on the ultraviolet-visible light source, cover the light-shielding cover at the notch of the installation groove 14, and then the absorbance of the sample to be measured can be measured (using this method, the absorbance of substances in the wavelength range of 190nm to 760nm can be measured. The specific measurement process is the prior art and will not be elaborated here). After that, by analyzing the measured absorbance, the concentration value corresponding to the sample to be measured can be obtained. After the test is over, the colorimetric cuvette, the light-shielding cover, etc. can be stored in the second storage tank 21.

[0050] In detail, generally, a standard solution is first purchased, and the standard solution is diluted to obtain diluted solutions with different concentrations. Each diluted solution is added into the colorimetric cuvette respectively. Using the above operations, the absorbance corresponding to the diluted solution can be measured. After measuring the absorbances of multiple groups of diluted solutions, the relationship curve between the concentration value and the absorbance of the standard solution can be obtained. After that, when wanting to detect the concentration of an unknown-concentration sample to be measured, the above operation steps can be used to measure the absorbance of the sample to be measured, and then the measured absorbance is compared with the relationship curve between the concentration value and the absorbance of the standard solution, and the concentration value of the sample to be measured can be obtained.

[0051] In practical applications, to facilitate the adjustment of the rotation speed of the motor and the wavelength of the ultraviolet-visible light source, as Figure 1As shown, the entire test chamber further includes a first control panel 4 and a second control panel 5 provided on the side of the first storage box 1. The first control panel 4 is electrically connected to the motor, and the second control panel 5 is electrically connected to the ultraviolet-visible light source.

[0052] Specifically, generally the first control panel 4 has a first display screen. The first display screen has a start button and a stop button, and the rotational speed value of the motor can also be input on the first display screen to facilitate the control of the operation of the motor. In this way, when the start button is pressed, the first control panel 4 controls the operation of the motor to drive the permanent magnet to rotate. Generally, the second control panel 5 has a second display screen. The second display screen also has a start button and a stop button, and the wavelength of the ultraviolet-visible light source can also be input on the second display screen. The specific control processes are all prior arts and will not be elaborated here.

[0053] Furthermore, for the convenience of power supply to the relevant equipment in the test chamber, such as Figure 1 As shown, a power interface 15 is provided on the side of the first storage box 1. The power interface 15 is electrically connected to the motor, the ultraviolet-visible light source, the first control panel 4, and the second control panel 5. By connecting an external power supply through this power interface 15, the above-mentioned equipment can be powered.

[0054] In the specific implementation process, in order to better protect the equipment, instruments, or medicaments stored in the first storage slot 11 and the second storage slots 21, a first cover plate is detachably provided at the notch end of the first storage slot 11, and a second cover plate is respectively detachably provided at the notch ends of each second storage slot 21.

[0055] Generally, since the equipment in the first storage slot 11 is not required to be taken out during the test and only needs to be checked or taken out occasionally during maintenance, the first cover plate at the notch of the first storage slot 11 is generally rarely disassembled after being fixed and can be kept closed during the test. However, the instruments and medicaments in the second storage slots 21 need to be taken out for use during the test. Therefore, when the instruments or drugs need to be taken out from the notch of each second storage slot 21, the second cover plate is disassembled, and the second cover plate is fixed and closed again after the test. Through the settings of the first cover plate and the second cover plate, it can be ensured that the internal equipment, instruments, or medicaments will not topple during the movement process, playing a certain protective role.

[0056] In addition, in order to facilitate the fastening of the nut 32 on the inner surface of the bottom of the first storage box 1 when the above-mentioned support rod 3 needs to be installed during the test, the first cover plate can be made into a special shape to make way for the installation hole 13, making it more convenient to install the nut 32. The specific shape of the first cover plate is determined according to needs, and the present invention does not limit this.

[0057] Furthermore, for the convenience of processing and installation, such as Figure 3As shown in the figure, a plurality of partition plates 22 are detachably provided in the second storage box 2. Each partition plate 22 divides the interior of the second storage box 2 into a plurality of second storage slots 21, and each second cover plate is detachably connected to the corresponding partition plate 22. When installing the partition plate 22, a support leg storage space 61 and a fixing rod storage space are also left in the second storage box 2. At the same time, how each second storage slot 21 is specifically divided can be planned according to actual needs, and the present invention does not limit this.

[0058] More specifically, generally, opposite ends of each partition plate 22 respectively protrude outward to form a plurality of first bumps and a plurality of second bumps. A plurality of first slots are opened on the inner wall of the bottom surface of the second storage box 2, and each first bump can be inserted into the corresponding first slot to realize the fixation of each partition plate 22 to the second storage box 2. A plurality of second slots are respectively opened on each second cover plate, and each second bump can be inserted into the corresponding second slot to realize the fixation of each second cover plate to each partition plate 22. In this way, each partition plate 22 can be inserted into the corresponding first slot according to needs, or its insertion position can be freely adjusted to adjust the space of the second storage slot 21. Of course, the fixing method of each partition plate 22 to the second storage box 2 and the fixing method of each second cover plate can also adopt other structures, and this embodiment is only for illustrative purposes.

[0059] In practical applications, the outer walls of the bottom surfaces of the first storage box 1 and the second storage box 2 should be smooth and flat to meet the flatness when unfolded as a test bench. Generally, an anti-corrosion coating is applied to the outer walls of the bottom surfaces of the first storage box 1 and the second storage box 2 to make them have strong wear resistance and strong acid and alkali corrosion resistance, meeting the workbench standards of professional laboratories. This anti-corrosion coating can adopt an epoxy resin coating with a thickness of 13 mm, or other anti-corrosion materials can be used according to needs. This embodiment is only for illustrative purposes.

[0060] In order to facilitate the operation of the operator after folding the test box, handles are provided on the outer walls of the sides of the first storage box 1 and the second storage box 2 opposite to the pivot connection positions.

[0061] Generally, in order to more intuitively distinguish the instruments or medicaments in the second storage slot 21, labels are pasted on each second cover plate to mark the names of the instruments or medicaments stored in the corresponding second storage slot 21.

[0062] Furthermore, in order to facilitate the test box to be more stably supported on the ground after being unfolded during use to meet the complex on-site working environment, as Figure 1 and Figure 3 shown, at least two telescopic support legs 6 are symmetrically hinged in the first storage box 1 and the second storage box 2 respectively, and support leg storage spaces 61 are respectively left in the first storage box 1 and the second storage box 2.

[0063] Specifically, the number of telescopic support legs 6 is determined according to needs. For example, in this embodiment, two telescopic support legs 6 are respectively provided in the first storage box 1 and the second storage box 2. When in use, after the test box is unfolded, each telescopic support leg 6 is bent and unfolded to a position perpendicular to the bottom surface of the first storage box 1 or the second storage box 2, and then it is extended and adjusted to a suitable height, and then the test can be started. After the test is completed, the telescopic support legs 6 can be retracted to the shortest, and then after being bent, they can all be put back into the support leg storage space 61 for storage, which is more convenient to operate. The telescopic support legs 6 can be adjusted in height arbitrarily, and the specific structure for realizing the telescoping is the prior art and will not be elaborated here.

[0064] In actual use, in order to make the telescopic support legs 6 more stable when supporting, as Figure 7 shown. The entire test box further includes fixing rods 7 having the same number as the telescopic support legs 6, and a fixing rod storage space is left in the second storage box 2. One end of each fixing rod 7 is detachably connected to the corresponding telescopic support leg 6, and the other end is detachably connected to the side surface of the first storage box 1 or the side surface of the second storage box 2.

[0065] Specifically, as Figure 7 , Figure 8 and Figure 9 shown, a card slot 71 is respectively formed on the side walls at both ends of each fixing rod 7, and a clamping block 8 is respectively provided on the side wall of the telescopic support leg 6, the side surface of the first storage box 1, and the side surface of the second storage box 2. Each clamping block 8 can be clamped in the card slot 71.

[0066] In this way, when in use, after each telescopic support leg 6 is adjusted to a suitable height, both ends of the fixing rod 7 are respectively fixed on the telescopic support leg 6 and the side surface of the first storage box 1 or the side surface of the second storage slot 21, and the fixing rod 7 is placed obliquely, enclosing a triangle with the telescopic support leg 6 and the side surface of the first storage box 1 or the side surface of the second storage slot 21, thereby playing a role in enhancing the structural stability. After the test is completed, the fixing rod 7 can be removed and then put back into the fixing rod storage space for storage, which is more convenient.

[0067] The shapes of the card slot 71 and the clamping block 8 can be determined according to actual needs, as long as it is convenient for the fixation and disassembly of the two. For example, in this embodiment, as Figure 8 and Figure 9 shown, the card slot 71 is a circular card slot, and the clamping block 8 includes a connecting rod 81 and a circular clamping cap 82 that are fixedly connected to each other. The connecting rod 81 is fixed to the side wall of the corresponding telescopic support leg 6, the side surface of the first storage box 1, or the side surface of the second storage slot 21, and the circular clamping cap 82 can be clamped in the corresponding circular card slot.

[0068] In addition, the material of the entire test box is preferably alloy material to make the overall structure more stable, durable and easy to carry.

[0069] In more detail, the operation process of the test box in this embodiment is as follows:

[0070] Open the test box, take out the instruments and reagents, and unfold the test box to the working position. After unfolding, it can be used as a test table. At the same time, bend the telescopic support leg 6 in the support leg storage space 61 to unfold it and adjust it to a suitable height, and then fix the fixing rod 7. At this point, the simple test bench is built and the operation is simple and convenient.

[0071] Various inspection tests can be carried out on the test bench. After the inspection task is completed, the test box can be folded to the storage position and recovered, and can be transported to other projects for use.

[0072] The above are only exemplary embodiments of the present invention and are not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
