DETAILED DESCRIPTION

[0022] In order to facilitate a better understanding of the present invention, the following examples are used to illustrate the present invention in conjunction with the accompanying drawings. These examples belong to the protection scope of the present invention, but do not limit the protection scope of the present invention.

[0023] Example 1

[0024] A colorimetric tube colorimetric detection device, such as Figure 1-Figure 3 As shown, it includes a body 1, a detection component 2, the detection component 2 includes a light source system 21, a detector 22, and a display 23 which are arranged on the body 1 at a distance; it also includes: a sealing frame 11, which is arranged on the body 1, and the detection component 2 is located in the area enclosed by the sealing frame 11 and the body 1; a tube mounting component 3, including a tube mounting plate 31 embedded in the body 1, and a tube hole 32 is provided on the tube mounting plate 31; the tube mounting plate 31 is partially located in the body 1 between the light source system 21 and the detector 22; the light emitted by the light source system 21 toward the detector 22 is above the tube hole 32.

[0025] like Figure 1-Figure 2 As shown, the door leaves 12 are disposed on both sides of the sealing frame 11 so that only one pipe hole 32 is provided in the area enclosed by the two sets of door leaves 12 .

[0026] The light source system and detector are arranged on the top of the body; the display is arranged on one side of the body for displaying the data of spectroscopic colorimetric analysis; the light source system mainly includes light source, spectrometer and other components; the light source system, detector and display are all existing products, which are installed and connected using existing technology to achieve the purpose of spectroscopic colorimetry.

[0027] The sealing frame, door leaf and machine body are combined so that the light source system is in a closed and light-proof area; under the premise of ensuring the sealing effect, the sealing frame and the machine body can be movably connected so that the sealing frame can be removed during inspection or maintenance.

[0028] The tube holes on the tube tray are used to place colorimetric tubes, and the colorimetric tubes containing sample solutions can be placed directly in the tube holes. During colorimetric analysis, the light emitted from the light source system passes through the colorimetric tube solution above the tube holes and is then received by the detector. Therefore, the part of the colorimetric tube that is not in the tube holes should have a certain sample solution height to meet the colorimetric requirements.

[0029] like Figure 1 , Figure 2 , Figure 5As shown, the tube loading plate 31 is an annular structure, and the detector 22 and the rotating device 41 are located inside the annular structure.

[0030] like Figure 2 As shown, there are a plurality of pipe holes 32 equidistantly spaced in the radial direction of the pipe loading disk 31 .

[0031] like Figure 1-Figure 2 As shown, the detection device also includes: a rotating component 4, including a rotating device 41 arranged in the body 1, and a rotating gear 42 is provided on the output shaft of the rotating device 41; the rotating gear 42 is provided with a rack on the inner side of the tube loading disk 31, so that the rotating gear 42 drives the tube loading disk 31 to rotate through gear meshing.

[0032] like Figure 1 , Figure 2 As shown, the sealing frame 11 and the door leaf 12 are at appropriate heights, allowing the colorimetric tube to enter and exit the sealing frame 11.

[0033] The rotating device can be a motor; an installation groove is opened on the body in the sealing frame area, and the rotating device (i.e., the motor) is installed in the groove, and its output shaft is connected to the rotating gear, and the rotating gear is meshed with the rack on the side of the tube loading disk on its side. The rack can be set only in a partial height area of ​​the side of the tube loading disk, and the top of the tube loading disk is flush with the body; a cover can be set on the top of the installation groove to cover the rotating device.

[0034] In the process of analyzing samples in the laboratory, it is often encountered that a large number of samples need to be tested and analyzed. In order to improve efficiency, multiple tube holes can be set at equal intervals on the tube loading tray, and then the colorimetric tube samples to be analyzed are placed in the tube holes in turn; when the colorimetric analysis of a colorimetric tube sample is completed, the rotating device is started to drive the tube loading tray to rotate to a suitable angle, and push open the door leaf on one side to enter the optical path in the sealed frame for colorimetry; after the colorimetry is completed, the rotating device is started again, and the rotating gear is engaged to make the tube loading tray rotate a certain angle again, so that the colorimetric tube that has been tested moves forward and pushes open the door leaf on the other side to leave the sealed frame area, and the next colorimetric tube to be analyzed pushes open the door leaf and enters the optical path again; the above operation is repeated until all the colorimetric tubes on the tube loading tray are analyzed; during the detection process, the colorimetric tube sample that has been tested on the tube loading tray can be taken out, and then the marked colorimetric tube sample with detection can be put in to improve the detection efficiency.

[0035] Since the tube holes on the tube loading disk are arranged at equal intervals, in order to ensure that the time that the colorimetric tube to be tested is on the optical path can meet the detection requirements, the rotation speed of the motor can be set constant; when the motor rotates, the detection component is in standby mode; after the tube loading disk rotates for a certain period of time, the colorimetric tube to be tested enters the appropriate position of the sealing frame, at which time the motor is in standby mode and the detection component starts working; this process is repeated until the sample detection is completed.

[0036] Usage: Add the treated sample solution to a fixed volume into the colorimetric tube, and insert the colorimetric tube into each tube hole of the tube loading plate; turn on the power, the detection component enters the standby state, and the rotating device drives the tube loading plate to rotate; when a colorimetric tube pushes open the door leaf and enters the appropriate position in the sealing frame, the rotating device enters the standby state, the detection component starts, the light source system emits light, the light path passes through the colorimetric tube and is received by the detector, and the data is displayed on the display; after the detection is completed, the rotating device starts, and the detection component enters the standby state; the colorimetric tube after detection pushes open the door leaf to leave the sealing frame area, and the next colorimetric tube to be detected pushes open the door leaf to enter the sealing frame, and the above operation is repeated to perform sample detection.

[0037] Example 2

[0038] like Figure 1 , Figure 2 As shown, a torsion spring is provided between the door leaf 12 and the sealing frame 11, so that the door leaf 12 can be opened when subjected to external force, and can be reset and closed after the external force disappears.

[0039] like Figure 1 , Figure 5 As shown, the tube assembly 3 further includes: a clamping member 33, which is arranged along the circumference of the inner side of the tube hole 32 and is used to clamp the outer side wall of the colorimetric tube.

[0040] Doors are provided on both sides of the sealing frame, and the direction in which the doors open is consistent with the direction in which the tube loading disk rotates. In order to ensure that the sealing frame area is sealed and light-proof, and to facilitate the colorimetric tubes of the samples to be tested to enter and exit the sealing frame; therefore, opaque doors are provided on the sealing frame to ensure the accuracy of colorimetric analysis; the torsion springs provided between the door leaves and the sealing frame will deform when the door leaves are opened by external force, causing the door leaves to open; after the external force disappears, the door leaves will reset and close due to the action of the torsion springs; this ensures that during the rotation of the rotating device, the colorimetric tubes enter the light path or come out of the light path through the door leaves as the tube loading disk rotates, and after the entry and exit actions are completed, the door leaves are in a closed state to prevent light from passing through the sealing frame area.

[0041] Since the colorimetric tube is higher than the colorimetric cell, in order to ensure that the colorimetric tube loaded into the tube loading tray will not be knocked over or shaken when rotating, etc., and the tube diameters and tube heights of colorimetric tubes of different specifications are different, a clamping member 33 is provided at the tube hole.

[0042] like Figure 5 As shown, the clamping piece is arranged on the circumference of the inner side of the tube hole, including a spring and a clamping plate arranged at the end of the spring. The clamping plate can be provided with anti-slip grooves, and multiple groups of clamping pieces can be provided as needed; the colorimetric tube can be fixed by the clamping piece to prevent it from being knocked over or shaking when rotating, which can ensure the consistency of the optical path and can meet the needs of colorimetric tubes of different specifications, thereby improving the scope of application.

[0043] The light source system, detector, display, rotating device, etc. involved in the utility model are not innovative points created by the present invention, and the specific models are not described here, and the circuit connections of each component are all existing technologies.

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the statement "including an element defined by ... does not exclude the existence of other identical elements in the process, method, article or device including the element".
