Semi-automatic biochemical analyzers are clinically used to measure the levels of various components in human blood and urine, quantifying biochemical analysis results and providing reliable numerical evidence for the diagnosis of various patient diseases. They are essential routine testing equipment in clinical practice.

[0003] According to the Chinese patent publication number CN205538643U, a sample injection device for a biochemical analyzer includes a cuvette system and a sample injection system. The sample injection system includes two specimen placement rods that are parallel to each other and form a movable channel between the two rods, a base disposed below the specimen placement rods, a movable rod that is parallel to the specimen placement rods and located above the specimen placement rods, a linear stepper motor disposed at one end of the movable rod, a specimen moving member disposed at the other end of the movable rod, a spring disposed parallel to the two specimen placement rods, and a baffle mounted at the end of the spring adjacent to one end of the specimen moving member.

[0004] In the above scheme, a placement plate and a through hole are used to place the test tubes containing biochemical materials, resulting in the following disadvantages in the early stage: when the test tube is inside the through hole, it may shake inside the through hole due to insufficient position, affecting the monitoring and analysis of the test tube. Utility Model Content

[0005] The purpose of the utility model is to provide a sample injection device for a biochemical analyzer, so as to solve the problem that the sample injection device may shake inside a through hole due to an insufficiently firm position, thereby affecting the monitoring and analysis of a test tube.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical solution: a sample feeding device for a biochemical analyzer, comprising a feeding frame, a sliding plate is slidably provided on the top surface of the feeding frame, a plurality of storage holes are provided on the top surface of the sliding plate, a plurality of fixed plates are fixed to the bottom surface of the sliding plate, an extrusion plate is slidably provided on one side of the fixed plate, a sliding rod is fixed on one side of the extrusion plate, a sliding hole is provided on one side of the fixed plate, the sliding hole and the sliding rod are slidably inserted, a spring is surrounded by the surface of the sliding rod, one section of the spring is fixed to one side of the extrusion plate, and the other end of the spring is fixed to one side of the fixed plate.

[0007] Preferably, two threaded rings are fixed to the ground of the sliding plate, a driving motor is fixed to one side of the feed frame, a rotating hole is opened on one side of the feed frame, the output shaft of the driving motor is rotatably inserted into the rotating hole, a section of the output shaft of the driving motor is fixed with a threaded rod, and the threaded rod is threadedly connected to the threaded ring.

[0008] Preferably, two limiting grooves are provided on the top surface of the feed frame, and two limiting bars are fixed to the ground of the sliding plate, and the limiting grooves and the limiting bars are slidably arranged.

[0009] Preferably, a supporting folding plate is fixed to the ground of the sliding plate, and a plurality of elastic pads are fixed to the inner ground of the supporting folding plate.

[0010] Preferably, support plates are fixed on both sides of the bottom surface of the feed frame.

[0011] Preferably, a stabilizing plate is provided below the feed frame, and both sides of the top surface of the stabilizing plate are respectively fixed to the bottom surfaces of the two support plates.

[0012] Compared with the prior art, the sample injection device for a biochemical analyzer using the above technical solution has the following beneficial effects:

[0013] 1. When the biochemical sample is transported into the biochemical analyzer, the staff will first prevent the biochemical sample from entering the storage hole. When the test tube containing the biochemical sample is placed into the storage hole, as the test tube goes deeper into the storage hole, the test tube will exert a force on the two squeezing plates to move away from each other, thereby pushing the squeezing plates toward the two fixed plates and compressing the spring, thereby pushing the two squeezing plates closer to each other and exerting a squeezing force on the test tube, thereby increasing the firmness of the test tube in the storage hole.

[0014] Second, when the sliding plate slides on the top surface of the feed frame, it will drive the limit bar to slide synchronously inside the limit groove. When the biochemical sample tube is placed inside the storage hole, the bottom of the test tube is on the top surface of the elastic pad, preventing the test tube from hitting the support folding plate due to bumps during movement, thereby increasing the safety of the test tube during movement;

[0015] 3. When transporting the biochemical sample tubes to the biochemical analyzer, the staff will use the support plate to increase the height of the feed frame, so that the biochemical sample tubes can be lifted to the height of the biochemical analyzer feed port, and the stabilizing plate can be used to increase the stability of the biochemical sample during movement.
