Description

Technical Field

[0001] This utility model relates to the field of cell preparation technology, and in particular to a gun head locking mechanism for a cell preparation staining machine. Background Technology

[0002] Cell slide staining systems include sample preparation, staining, rinsing, and drying. These processes require precise aspiration and dispensing of various reagents, including fixatives, staining solutions, and buffers, to ensure accurate processing and staining of cell samples. As a key component of the pipette, the stability of the pipette tip is crucial for accurate reagent aspiration and dispensing. The precise quantity of reagents required in cell slide staining necessitates a pipette tip locking mechanism that ensures a tight connection between the tip and the pipette, preventing leakage and inaccurate aspiration volumes. This ensures the reproducibility and accuracy of experimental results. Furthermore, when processing multiple samples, avoiding cross-contamination between different samples is critical. A reliable pipette tip locking mechanism prevents accidental contamination of the tip during replacement and operation, and also prevents cross-contamination caused by reagent leakage during aspiration and dispensing. In addition, given the large volume of samples processed in laboratories, the pipette tip locking mechanism should facilitate quick tip replacement to improve efficiency. Its stability and reliability also reduce operational interruptions and repetitive work caused by loose or detached pipette tips.

[0003] With the deepening of cell biology and pathology research, the performance requirements for cell slide staining machines are becoming increasingly higher. The pipette tip locking mechanism is also constantly evolving to meet new demands. New locking mechanisms adopt intelligent designs that can automatically identify the specifications and types of pipette tips and perform adaptive locking. Some mechanisms also use more advanced materials and manufacturing processes, improving corrosion resistance and wear resistance and extending service life. However, when using clamps and clips to fix pipettes, the force is not easy to control, which can easily cause excessive compression of the pipette, leading to cracks or even breakage of the pipette. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a pipette tip locking mechanism for a cell slide staining machine, which aims to improve the problem that when using clamps and buckles to fix pipettes in the prior art, the force is not easy to control, which can easily cause excessive compression of the pipette, resulting in cracks or even breakage of the pipette.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pipette head locking mechanism for a cell slide staining machine, comprising a staining machine housing, a liquid storage tube slidably connected to the top of the staining machine housing, a pipette head shell fixedly connected to the bottom of the liquid storage tube, a vacuum generating device disposed inside the pipette head shell, an adsorption chamber connected to the rear side of the vacuum generating device, a sealing column fixedly connected to the bottom of the vacuum generating device, multiple air channels opened at the top of the sealing column, a connecting pipe fixedly connected to the middle of the sealing column, the top of the connecting pipe communicating with the bottom of the liquid storage tube, a collar fixedly connected to the bottom of the connecting pipe, a pipette engaged on the outer wall of the collar, and an adjustment mechanism disposed on the top of the staining machine housing for adjusting the staining position.

[0006] As a further description of the above technical solution:

[0007] The adjusting mechanism includes a connecting block, the inner wall of which is fixedly connected to the outer wall of the liquid storage tube. A sliding groove is provided at the top center of the dyeing machine box, and the outer wall of the connecting block is slidably connected to the inner wall of the sliding groove. A motor is fixedly connected to the rear top of the dyeing machine box, and a gear is fixedly connected to the output end of the motor. A toothed strip is meshed with the outer wall of the gear, and an L-shaped plate is fixedly connected to the bottom center of the toothed strip. The bottom of the L-shaped plate is fixedly connected to the rear side of the connecting block.

[0009] A transparent plate is fixedly connected to the front right end of the dyeing machine housing, and a nameplate is fixedly connected to the front top of the dyeing machine housing.

[0010] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this invention, the pipette is initially engaged from the bottom of the connecting tube using a collar. Then, a vacuum generator is used to generate suction, which draws air between the sealing column and the pipette from the air channel into the adsorption chamber, enabling the sealing column and the pipette to adsorb each other. This strengthens the fixation of the pipette and prevents excessive mechanical compression and damage to the pipette, thus extending its service life. At the same time, the adsorption process avoids liquid contamination and ensures the accuracy of experimental results.

[0022] 2. In this utility model, the rotation of the gear is driven by the motor, and the rotation of the gear causes the rotation of the meshing toothed strip, thereby moving the L-shaped plate. The movement of the L-shaped plate causes the connecting block to move along the slide groove, thereby moving the dyeing machine box. This allows for adjustment of the position of the pipette, facilitating replacement and dyeing operations. At the same time, it provides a relatively stable power transmission, avoiding shaking and instability caused by manual operation. Attached Figure Description

An adjustment mechanism 2 is provided on the top of the staining machine housing 1. The adjustment mechanism 2 is used to adjust the staining position.

[0033] Specifically, the storage tube 3 is not only a container for storing the dyeing solution, but its bottom is also fixedly connected to the nozzle housing 4.

The bottom of the L-shaped plate 206 is fixedly connected to the rear side of the connecting block 201.

[0035] Specifically, the connecting block 201 can be fixedly connected to the outer wall of the liquid storage tube 3, ensuring the stability and synchronous movement between the connecting block 201 and the liquid storage tube 3. A sliding groove 202 is provided in the middle of the top of the dyeing machine box 1, providing a sliding path for the connecting block 201, so that the connecting block 201 can slide on the inner wall of the sliding groove 202, ensuring the adjustability of the adjustment mechanism 2. The outer wall of the gear 204 meshes with the toothed strip 205 to form a transmission system. The L-shaped plate 206 enables the toothed strip 205 to be fixedly connected to the rear side of the connecting block 201, achieving a synchronous movement effect.

[0036] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 A display screen 14 is fixedly connected to the front left side of the dyeing machine box 1. A heat sink 15 is fixedly connected to the left side of the dyeing machine box 1. A controller 22 is fixedly connected to the bottom of the front left side of the dyeing machine box 1.

Support columns 16 are fixedly connected to the bottom of the dyeing machine box 1 on all four sides. Anti-slip pads 17 are fixedly connected to the bottom of each support column 16.

[0037] Specifically, the display screen 14 provides an intuitive control interface for the operator, the heat sink 15 dissipates the heat generated by the chassis during operation to ensure stable operation of the equipment, and the controller 22 facilitates convenient control by the operator. In order to ensure the stability and durability of the dyeing chassis 1, support columns 16 are fixedly connected to all four sides of its bottom. These support columns 16 not only provide structural support, but also enhance the stability of the equipment in various working environments through the anti-slip pads 17 fixedly connected to their bottoms.

[0038] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3Two fixing blocks 18 are fixedly connected to the front end of the top inner side of the dyeing machine box 1. Lighting tubes 19 are fixedly connected between adjacent fixing blocks 18. A transparent plate 12 is fixedly connected to the right front end of the dyeing machine box 1.

[0039] Specifically, the lighting tube 19 ensures sufficient light during the dyeing process, the transparent plate 12 allows the operator to clearly observe the dyeing process, and for identification and explanation, a nameplate 13 is fixedly connected to the top front side of the dyeing machine housing 1, which records relevant equipment information. For safety and stability, an anti-slip plate 20 is fixedly connected to the bottom inner side of the dyeing machine housing 1 to prevent slippage during the dyeing process.

[0040] Working principle: The pipette 11 is initially engaged from the bottom of the connecting tube 9 through the collar 10. At this time, the top of the pipette 11 is in contact with the sealing column 7. Then, the vacuum generator 5 generates suction, which transmits the air between the sealing column 7 and the pipette 11 through the air channel 8 into the adsorption chamber 6, so that the sealing column 7 and the pipette 11 achieve adsorption and strengthen the fixation of the pipette 11. When it is necessary to remove the pipette 11, the gas in the adsorption chamber 6 is discharged to squeeze the pipette 11, making it easy to remove the pipette 11. This adsorption fixation method is relatively gentle and will not cause excessive mechanical compression and damage to the pipette 11, which helps to extend its service life. At the same time, during the adsorption process, a good seal is formed between the sealing column 7 and the pipette 11, which can prevent liquid leakage and the entry of outside air, avoid liquid contamination, and ensure the accuracy of experimental results.

[0041] The rotation of the gear 204 driven by the motor 203 causes the rotation of the meshing toothed strip 205, thereby moving the L-shaped plate 206. The movement of the L-shaped plate 206 causes the connecting block 201 to move along the slide groove 202, thereby moving the dyeing machine box 1. This allows for adjustment of the position of the pipette 11, facilitating replacement and dyeing operations. At the same time, it provides a relatively stable power transmission, avoiding shaking and instability caused by manual operation.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
