In the process of chemiluminescence analysis, accurate, fast and stable transportation of samples is the key to ensure the accuracy of the analysis results. The existing sample conveying mechanism has certain defects when conveying samples. For example, in the Chinese patent with the publication number of "CN 207248899 U", a sample conveying system for a chemiluminescence instrument is disclosed. The device is independently formed into a module, and has a horizontal conveying channel and a control system; the conveying channel includes a sample feeding interconnection structure, a sample loading area, a sample processing area, a sample withdrawal area, and a sample withdrawal interconnection structure in sequence along the X direction; the sample loading area has a sample loading conveyor belt mechanism for conveying the test tube rack forward along the Y direction, and the sample loading conveying mechanism has a second micro switch, and the second micro switch automatically controls the start of the sample loading conveyor belt mechanism. When the device conveys samples, although the test tube rack can be transported, a limit structure adjusted according to the test tube rack is not set, and the test tube rack is prone to tipping during movement, causing the sample to be contaminated or unusable. The stability of the device in conveying the test tube rack is poor, and the conveying efficiency is low. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 one Figure 6 As shown, the utility model provides the following technical solutions: a sample conveying mechanism for a chemiluminescent instrument, comprising a loading member and a conveying member for conveying samples along a horizontal path, a loading cavity for driving the sample to move up and down relative to a horizontal plane is formed on the loading member, and the loading member is installed at the discharge end of the conveying member;

[0027] Two movable guide members are symmetrically installed above the conveying member, and the moving directions of the two guide members are perpendicular to the horizontal path. The two guide members move to make them contact with the symmetrical sides of the sample, and the two guide members form a guide for the sample to move along a preset direction, which is parallel to the horizontal path.

[0028] In this embodiment, when personnel need to transport samples, a test tube rack containing multiple test tube samples is placed on the conveying member. After the test tube rack is placed, the guide member moves relative to the conveying member until the two guide members contact the two sides of the test tube rack on the conveying member. The conveying member works to drive the test tube rack to move between the two guide members until the test tube rack moves above the loading member. In the process of the test tube rack moving from the conveying member to the loading member, the guide member limits the test tube rack to prevent the test tube rack from falling during the movement. The loading member works to push the test tube rack upward, and the personnel can take the test tube rack and transfer it to the chemiluminescence instrument for testing, thereby improving the transportation efficiency of the test tube rack.

[0029] Specifically, in one embodiment, regarding the above-mentioned conveying member:

[0030] like Figure 1-Figure 6 As shown, the conveying member includes a base frame 3, the top of the base frame 3 is sunken to form a mounting cavity 15, the interior of the mounting cavity 15 is symmetrically connected to two transmission rollers 18, and a conveyor belt 14 is sleeved between the two transmission rollers 18;

[0031] The base frame 3 is fixedly connected with a motor 2 , and an output end of the motor 2 is connected to a driving roller 18 .

[0032] In this embodiment, the drive roller 18 is supported by the installation cavity 15 on the base frame 3, and the conveyor belt 14 is supported by the drive roller 18. The test tube rack to be transported is placed on the conveyor belt 14, and the drive roller 18 is driven by the motor 2 to rotate in the installation cavity 15, so that the drive roller 18 drives the conveyor belt 14 to rotate, and the conveyor belt 14 drives the test tube rack to move in the direction of the upper material.

[0033] Specifically, in one embodiment, regarding the above-mentioned loading piece:

[0034] like Figure 1-Figure 6 As shown, the loading part includes a side frame 17, which is horizontally fixedly connected to one side of the base frame 3, and an electric push rod 10 is fixedly connected to the bottom of the side frame 17, a loading plate 8 is arranged above the side frame 17, and a moving rod 11 is connected to the telescopic end of the top of the electric push rod 10, and the free end of the moving rod 11 moves through the side frame 17 and is fixedly connected to the bottom of the loading plate 8.

[0035] In this embodiment, when the conveyor belt 14 drives the test tube rack to move to the loading plate 8, the side frame 17 is supported by the base frame 3, and the electric push rod 10 is supported by the side frame 17. The electric push rod 10 drives the moving rod 11 to move, so that the moving rod 11 drives the loading plate 8 to move up and down, and the loading plate 8 drives the test tube rack to move up and down, so that personnel can take the test tube rack on the loading plate 8.

[0036] In addition, in the present invention, in order to support the base frame 3 and the side frame 17, as shown in FIG. Figure 1-Figure 6 As shown, the bottom of the base frame 3 and the side frame 17 are fixedly connected with a bottom rod 16.
