Description

Technical Field

[0001] This utility model relates to the field of test tube fixation technology, and in particular to a test tube fixation device for a dry immunoassay analyzer. Background Technology

[0002] Dry fluorescence immunoassay analyzers are mainly used to measure bioactive compounds in very low concentrations. Chemiluminescence immunoassay combines highly sensitive chemiluminescence assays with highly specific immunoreactions, and is used for the detection and analysis of antigens, haptens, antibodies, hormones, enzymes, fatty acids, vitamins, and drugs. Dry fluorescence immunoassay analyzers require test tubes to store the samples to be tested. These tubes are secured using test tube racks. Traditional test tube racks are of two types: one type connects directly to the dry fluorescence immunoassay analyzer and is inserted into the analyzer via slots, allowing the analyzer's own pipette tip to directly draw samples from the tubes; the other type is separate from the analyzer and is a standard test tube rack placed outside the analyzer.

[0003] Existing tube fixing devices for dry immunoassay analyzers are inconvenient for securing multiple tubes during actual use. Tubes that are not properly secured are susceptible to shaking or bumping due to external forces, affecting their usability. Therefore, we propose a tube fixing device for dry immunoassay analyzers to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of fixing multiple test tubes during actual use, and the fact that test tubes without proper fixing can be shaken or bumped by external forces, affecting their use. Therefore, this invention proposes a test tube fixing device for a dry immunoassay analyzer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A test tube fixation device for a dry immunoassay analyzer, comprising:

[0007] The system comprises a base, a limiting plate, a fixing sleeve, a clamping sleeve, a horizontal plate, an adjusting plate, and a plug rod. The limiting plate is fixedly connected to the top of the base. There are four fixing sleeves and four clamping sleeves, which are equidistantly fixedly connected to the top of the base. The four clamping sleeves are equidistantly slidably connected to the top of the base. The horizontal plate is slidably connected to the top of the base, and the rear side of the horizontal plate is fixedly connected to the front side of the clamping sleeve. The right side of the horizontal plate extends to the outside of the base. The left side of the adjusting plate is fixedly connected to the right side of the horizontal plate. The plug rod is slidably connected to the rear side of the adjusting plate. A slot is provided on the right side of the base, and the plug rod engages with the slot.

[0008] A snap-fit ​​mechanism is connected to the insertion rod, and the snap-fit ​​mechanism is used to move the insertion rod to fix the clamp.

[0009] As a preferred embodiment of this utility model, the locking mechanism includes: a movable frame, an inclined plate, and an adjusting rod;

[0010] The movable frame is slidably connected to the rear side of the adjusting plate, the inclined plate is slidably connected to the rear side of the adjusting plate, and the top of the inclined plate is fixedly connected to the top of the movable frame. The adjusting rod is fixedly connected to the bottom of the insert rod, and the rear side of the adjusting rod is rotatably connected to an adjusting wheel, the outer wall of the adjusting wheel being in active contact with the top of the inclined plate.

[0011] In a preferred embodiment of this utility model, a control plate is slidably connected to the right side of the adjustment plate, and the left side of the control plate is fixedly connected to the right side of the movable frame.

Beneficial effects

[0015] 1. The adjustment plate facilitates the movement of the horizontal plate, which in turn moves the clamp. The clamp and the fixed sleeve work together to hold and fix the test tube. The insertion rod and the slot work together to fix the horizontal plate and thus the clamp.

[0016] 2. When the control panel is moved, the moving frame will move upward. The movement of the moving frame will compress the return spring, which will deform and store force. At the same time, the movement of the moving frame will cause the inclined plate to move upward. The movement of the inclined plate will contact the adjusting wheel and push the adjusting wheel to move laterally, thereby causing the adjusting rod and the insert rod to move to the right. The movement of the insert rod will compress the push spring, and at the same time, the movement of the insert rod will disengage from the slot, thereby unlocking the horizontal plate and the clamp.

[0017] This invention uses a simple structure to fix the adjusting plate, thereby fixing or unlocking multiple clips. Through the cooperation between the clips and the fixing sleeve, it achieves the effect of fixing or unlocking multiple test tubes at the same time, which is convenient to use and prevents the test tubes from shaking or bumping into each other due to external forces, thus having good practicality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0024] Reference Figures 1-4 A test tube fixation device for a dry immunoassay analyzer, comprising:

[0025] The base consists of a base 1, a limiting plate 2, a fixing sleeve 3, a clamping sleeve 4, a horizontal plate 5, an adjusting plate 6, and a plug rod 12. The limiting plate 2 is fixedly connected to the top of the base 1. There are four fixing sleeves 3 and four clamping sleeves 4. The four fixing sleeves 3 are fixedly connected to the top of the base 1 at equal intervals. The four clamping sleeves 4 are slidably connected to the top of the base 1 at equal intervals. The horizontal plate 5 is slidably connected to the top of the base 1, and the rear side of the horizontal plate 5 is fixedly connected to the front side of the clamping sleeve 4. The right side of the horizontal plate 5 extends to the outside of the base 1. The left side of the adjusting plate 6 is fixedly connected to the right side of the horizontal plate 5. The plug rod 12 is slidably connected to the rear side of the adjusting plate 6. A slot is provided on the right side of the base 1, and the plug rod 12 engages with the slot.

[0026] The snap-fit ​​mechanism is connected to the insertion rod 12 and is used to move the insertion rod 12 to fix the clamp 4.

[0027] Through the above mechanism: the adjusting plate 6 facilitates the movement of the horizontal plate 5, thereby moving the clamp 4; the clamp 4 cooperates with the fixed sleeve 3 to facilitate the clamping and fixing of the test tube; and the insertion rod 12 cooperates with the slot to facilitate the fixing of the horizontal plate 5 and thus the clamp 4.

[0028] As a preferred embodiment of the present invention, the snap-fit ​​mechanism includes: a movable frame 8, an inclined plate 10, and an adjusting rod 11;

[0029] The movable frame 8 is slidably connected to the rear side of the adjusting plate 6, and the inclined plate 10 is slidably connected to the rear side of the adjusting plate 6. The top of the inclined plate 10 is fixedly connected to the top of the movable frame 8. The adjusting rod 11 is fixedly connected to the bottom of the insertion rod 12, and the rear side of the adjusting rod 11 is rotatably connected to the adjusting wheel. The outer wall of the adjusting wheel is in movable contact with the top of the inclined plate 10. When the control plate 7 moves, it will drive the movable frame 8 to move upward. At the same time, the movement of the movable frame 8 will drive the inclined plate 10 to move upward. The movement of the inclined plate 10 will contact the adjusting wheel and push the adjusting wheel to move laterally, thereby driving the adjusting rod 11 and the insertion rod 12 to move to the right. The movement of the insertion rod 12 will compress the pushing spring 13. At the same time, the movement of the insertion rod 12 will disengage from the slot, thereby unlocking the horizontal plate 5 and the clamp 4.

[0030] As a preferred embodiment of this utility model, a control plate 7 is slidably connected to the right side of the adjustment plate 6, and the left side of the control plate 7 is fixedly connected to the right side of the movable frame 8, so that the movable frame 8 can be easily moved by the control plate 7.

[0031] As a preferred embodiment of this utility model, a support plate is fixedly connected to the rear side of the adjusting plate 6, the movable frame 8 passes through the support plate, and a return spring 9 is fixedly connected to the bottom of the support plate. The bottom of the return spring 9 is fixedly connected to the top of the movable frame 8. The elastic force of the return spring 9 facilitates pushing the movable frame 8 to reset.

[0032] As a preferred embodiment of this utility model, a push spring 13 is fixedly connected to the rear side of the adjusting plate 6. The left side of the push spring 13 is fixedly connected to the right side of the insertion rod 12. The elastic force of the push spring 13 facilitates the lateral movement and reset of the insertion rod 12.

[0033] As a preferred embodiment of this utility model, a sliding groove is provided on the right side of the adjusting plate 6, and a slider is fixedly connected to the left side of the control plate 7. The outer wall of the slider is slidably connected to the inner wall of the sliding groove. Through the cooperation of the sliding groove and the slider, the control plate 7 can be conveniently limited, so that the control plate 7 can move stably and vertically.

[0034] The working principle of this utility model is as follows: In actual use, when it is necessary to fix the test tube, first push the control plate 7 upward. When the control plate 7 moves, it will drive the moving frame 8 upward. The movement of the moving frame 8 will compress the return spring 9. At this time, the return spring 9 will deform and store force. At the same time, the movement of the moving frame 8 will drive the inclined plate 10 upward. The movement of the inclined plate 10 will contact the adjusting wheel and push the adjusting wheel to move laterally, thereby driving the adjusting rod 11 and the insertion rod 12 to move to the right. The movement of the insertion rod 12 will compress the pushing spring 13. At the same time, the movement of the insertion rod 12 will disengage from the slot, thereby unlocking the horizontal plate 5. At this time, pushing the adjusting plate 6 will drive the horizontal plate 5 to move, thus... Move the clamp 4 forward, and the test tube to be fixed can be inserted into the limiting plate 2, so that the test tube is between the clamp 4 and the fixing sleeve 3. Then push the adjusting plate 6 backward. The movement of the adjusting plate 6 will move the clamp 4 backward. The movement of the clamp 4 will push the test tube. The test tube is clamped and fixed by the cooperation of the clamp 4 and the fixing sleeve 3. Then release the control plate 7. The reset spring 9 will push the moving frame 8 downward. The reset of the moving frame 8 will drive the inclined plate 10 to reset. At the same time, push the spring 13 to push the insertion rod 12 to move laterally and engage with the slot to fix the adjusting plate 6, so that the clamp 4 is fixed and the test tube is kept stable, thereby achieving the effect of fixing multiple test tubes at the same time.
