Description

Technical Field

[0001] The utility model belongs to the technical field of chemiluminescence analyzers, and in particular relates to a sample injection device for a chemiluminescence analyzer. Background Art

[0002] A chemiluminescence analyzer is an analytical instrument based on the principle of chemiluminescence, which involves the release and detection of photons during a chemical reaction. The operating principle of a chemiluminescence analyzer is based on the chemiluminescence reaction. In a specific chemical reaction, certain substances (such as luminescent substances) react with chemical reagents (such as oxidants), releasing photons. These photons are then captured by a detector and converted into electrical signals, which are then used to analyze the concentration levels of the reactants.

[0003] However, the existing device has no limiting function for the test tube during use, so it is easy for the test tube to fall off when the device changes direction, which will have a certain impact on the on-site environment. At the same time, it is difficult to seal the top of the test tube during use, which can easily cause the reagent to spill. Therefore, further improvement is needed. Utility Model Content

A lifting plate 4 is fixedly connected to the outer side of the plurality of connecting pieces 3, and a plurality of slots 5 are provided inside the connecting piece 3, and

[0031] The anti-slip mechanism is provided outside the slot 5 and includes:

[0032] Anti-slip pads 6 are provided on both sides of the top of the empty slot 5, wherein the top of one anti-slip pad 6 is slidably connected to the top of the connector 3, and the top of the other anti-slip pad 6 is fixedly connected to the top of the connector 3. One side of the outer side of the two anti-slip pads 6 is fixedly connected to the housing 7. The anti-slip pads 6 are used to wrap the test tube;

[0033] A clamping plate 8 is fixedly connected to both sides of the exterior of one of the housings 7, a spring 9 is fixedly connected to one side of the two clamping plates 8, a cylinder 10 is fixedly connected to the outer ends of the two springs 9, and a plate 11 is fixedly connected to the exterior of the two cylinders 10, and a rod 12 is fixedly connected to the top of one of the housings 7;

[0034] Multiple rod bodies 12 are fixedly connected to each other with two fixed rods 15, one of the fixed rods 15 is fixedly connected to a fixed plate 16 on the outside, a sliding column 17 is slidably connected to the inside of the fixed plate 16, and a sliding plate 18 is fixedly connected to the top of the sliding column 17. A limiting block 19 is fixedly connected to one side of the outside of the connecting member 3, and the anti-slip mechanism is used to limit the test tube.

[0035] There are two limit bars in a single group, and the outer surface of the connector 3 contacts the inside of the two limit bars, which can facilitate the connector 3 to perform the limiting work.

[0036] One of the shells 7 is slidably connected to the top of the connector 3 , and the bottoms of the two plates 11 are fixedly connected to both sides of the top of the connector 3 , respectively, which facilitates the fixing of the plates 11 .

[0037] The plurality of empty slots 5 are arranged and distributed in a linear shape, and the cross section of the limiting block 19 is set to be U-shaped, which can facilitate the arrangement and insertion of reagent tubes.

[0038] The sliding post 17 extends into the interior of the limiting block 19 , and the outer surface of the sliding post 17 contacts the interior of the limiting block 19 , which facilitates the sliding operation of the sliding post 17 .

[0039] The multiple springs 9 are all in a compressed deformation state, and the two clamping plates 8 are in contact with the top of the connecting member 3, which can facilitate the movement of the clamping plates 8.

[0040] The two anti-slip pads 6 are in contact with each other and are arranged in a perfect circle, which can facilitate the anti-slip pads 6 to wrap the test tube.

[0041] It should be noted that the existing device has no limit function for the test tube during use, so the test tube is easily dropped when the device changes direction, which will have a certain impact on the on-site environment. At the same time, it is difficult to seal the top of the test tube during use, which may easily cause the reagent to spill.

[0042] In this embodiment, when it is necessary to inject reagents, the staff first needs to place the installed test tube inside the empty slot 5 for injection, and then lift the lifting plate 4 to drive the connecting member 3 to move. During the movement, the connecting member 3 will synchronously enter between the two limit bars for limit sliding. After that, the staff can open the body 1 to inject the reagents inside for observation.

[0043] When the test tube needs to be taken out, the staff lifts the lifting plate 4 to drive the connecting part 3 out of the interior of the body 1, and then lifts the sliding plate 18 upward. During the lifting process, the sliding plate 18 will synchronously drive the sliding column 17 to move and leave one side of the limit block 19. At this time, since the sliding column 17 is no longer limited by the limit block 19, the spring 9 will quickly stretch and drive the card plate 8 to move. During the movement, the card plate 8 will drive the connected shell 7 to move. During the movement, the shell 7 will synchronously drive the anti-slip pad 6 to move. At this time, one of the anti-slip pads 6 will leave the outer side of the test tube, and then the test tube will be in an unlocked state, which makes it easy to take out the test tube.

[0044] In a further preferred embodiment of the present invention, the exterior of each of the plurality of rods 12 is provided with an anti-spill mechanism, which includes:

[0045] The connecting rod 13 has a bottom portion fixedly connected to the top portion of the rod body 12 .

[0046] The connecting rod 13 is configured to be L-shaped, and a sealing plate 14 is fixedly connected to one side of the outside of the connecting rod 13 , which facilitates the fixing of the connecting rod 13 .

[0047] The blocking plate 14 is located at the top of the empty slot 5 , and the blocking plate 14 and the empty slot 5 are in the same plane, which can facilitate the blocking work of the test tube by the blocking plate 14 .

[0048] In this embodiment, when a new test tube needs to be injected and the reagent inside needs to be prevented from spilling out, the staff needs to lift the sliding plate 18 upward to drive the sliding column 17 to move, and then insert the sliding column 17 into the interior of the limit block 19. During this process, the sliding column 17 will drive the fixed plate 16 to move, and the fixed plate 16 will synchronously drive the fixed rod 15 to move during the movement. The fixed rod 15 will synchronously drive the rod body 12 and the connecting rod 13 to move during the movement. At the same time, the connecting rod 13 will drive the blocking plate 14 to block the opening at the top of the test tube. During the movement of the rod body 12, it will also drive the shell 7 and the card plate 8 to move, the spring 9 to compress, and the anti-slip pad 6 to wrap the test tube, thereby locking the test tube and preventing the reagent from spilling out.

[0049] In summary, during the movement of the rod 12 , the housing 7 and the clamping plate 8 are driven to move, the spring 9 is compressed, and the anti-slip pad 6 wraps the test tube, thereby achieving the locking of the test tube.

[0050] Compared with related technologies, the invention can not only limit the test tube, but also seal the opening.
