Technical Field

[0001] The utility model relates to the technical field of the structure of a sample tube fixing component, in particular to a sample tube fixing component of a flow cytometer. Background Art

[0002] Flow cytometers are used to analyze substances contained in cells collected from the human body, and then screen for human diseases. Flow cytometers need to be used together with sample tube fixing components to analyze cells collected in sample tubes. The function of the sample tube fixing component is to fix the sample tube with a large diameter and an arc-shaped bottom, so as to facilitate the subsequent flow cytometer to analyze the cells added to the sample tube.

[0003] A laboratory uses Figure 1 The sample tube fixing assembly shown is used to fix the sample tube with a large diameter and an arc-shaped bottom. The sample tube fixing assembly includes a machine table 1, two vertical plates 2 fixedly mounted on the top surface of the machine table 1, and adjusting screws 3 are rotatably installed in the two vertical plates 2. The nut of the adjusting screw 3 is located on the outer side of the vertical plate 2, and the threaded section of the adjusting screw 3 extends to the inner side of the vertical plate 2, and a nut 4 is threadedly connected on the extended end. A nylon block 5 is fixedly provided on the top surface of the nut 4, and an arc-shaped groove 6 is opened on the inner end surface of the nylon block 5. A light rod 7 is fixedly provided on the outer end surface of the nylon block 5, and the other end of the light rod 7 slides through the vertical plate 2; the arc-shaped grooves 6 of the two nylon blocks 5 are opposite to each other on the left and right.

[0004] The method for the sample tube fixing component to fix the sample tube with a large diameter and an arc-shaped bottom is:

[0005] S1. The worker takes out a sample tube 8, supports the curved surface at the bottom of the sample tube 8 on the machine table 1, and ensures that the sample tube 8 is between the two curved grooves 6. At the same time, the worker holds the sample tube 8 with his left hand. Figure 2 As shown;

[0006] S2. The worker uses his right hand to turn the adjusting screw 3 on the left side, and the adjusting screw 3 drives the nut 4 connected thereto to move rightward, and the nut 4 drives the nylon block 5 connected thereto to move rightward synchronously, and the arc groove 6 of the nylon block 5 moves toward the sample tube 8. When the arc groove 6 rests on the left outer cylindrical surface of the sample tube 8, the worker stops turning the adjusting screw 3;

[0007] S3. The worker turns the adjusting screw 3 on the right side with his right hand, and the adjusting screw 3 drives the nut 4 connected thereto to move to the left, and the nut 4 drives the nylon holding block 5 connected thereto to move to the left synchronously, and the arc groove 6 of the nylon holding block 5 moves toward the sample tube 8. When the adjusting screw 3 on the right side is turned a certain number of times, the sample tube 8 is just fixed between the two nylon holding blocks 5. When the holding is tight, the worker releases his left hand holding the sample tube 8.

[0008] S4. The worker operates the flow cytometer to analyze the cells in the sample tube 8.

[0009] However, although this sample tube fixing assembly can fix sample tubes with large diameters and curved bottoms, it still has the following technical defects in actual operation:

[0010] In steps S2-S3, the worker needs to turn the adjusting screw 3 twice to fix the sample tube 8 between the two nylon blocks 5, and it takes a long time to turn the adjusting screw 3 multiple times to close the two nylon blocks 5, thereby increasing the fixing time of the sample tube 8 and reducing the fixing efficiency of the sample tube 8. Therefore, there is an urgent need for a sample tube fixing component that can shorten the sample tube fixing time and improve the sample tube fixing efficiency. Utility Model Content

DETAILED DESCRIPTION

[0032] The utility model is further described below in conjunction with the accompanying drawings, and the protection scope of the utility model is not limited to the following:

[0033] like Figure 4~Figure 8As shown, a sample tube fixing assembly of a flow cytometer comprises a machine platform 1, a vertical plate 2 and a right clamping block 9 are fixedly provided on the top surface of the machine platform 1, an arc groove 6 is provided on the left end surface of the right clamping block 9, the vertical plate 2 is located on the left side of the right clamping block 9, a square rod 10 is slidably penetrated in the vertical plate 2, a square groove is provided in the vertical plate 2, the square rod 10 is slidably matched with the square groove, an inclined surface 11 is provided on the bottom surface of the left end portion of the square rod 10, a left clamping block 12 is fixedly provided on the right end portion of the square rod 10, an arc groove 6 is provided on the right end surface of the left clamping block 12, the arc groove 6 of the left clamping block 12 is opposite to the arc groove 6 of the right clamping block 9 left and right, a horizontal spring 13 is fixedly provided between the left end surface of the left clamping block 12 and the vertical plate 2; a plurality of supporting legs are fixedly provided on the bottom surface of the machine platform 1.

[0034] An iron plate 14 is welded to the bottom surface of the left end of the machine 1, and a rod 15 slides through the iron plate 14. A guide hole is opened in the iron plate 14, and the rod 15 slides through the guide hole. A magnetic block 16 and a lifting plate 17 are fixed to the bottom of the rod 15 in sequence. A vertical spring 18 is sleeved on the outside of the rod 15. The top of the vertical spring 18 is fixed to the bottom surface of the iron plate 14, and the bottom end of the vertical spring 18 is fixed to the top surface of the lifting plate 17. A wedge plate 19 is fixed to the top of the rod 15, and the wedge surface of the wedge plate 19 contacts the inclined surface 11 of the square rod 10.

[0035] A pull ring 20 is fixedly disposed at the bottom of the lifting plate 17. The bottom surface of the left holding block 12 is in contact with the top surface of the machine platform 1.

[0036] The working process of the utility model is as follows:

[0037] S1. The worker takes out a sample tube 8 and inserts the sample tube 8 from top to bottom into the arc groove 6 of the right clamping block 9. Fig. 9 As shown, the curved surface at the bottom of the sample tube 8 is supported on the machine table 1, and at the same time, the worker holds the sample tube 8 with his left hand;

[0038] S2. The worker lifts the pull ring 20 with his right hand, and the pull ring 20 drives the lifting plate 17 to move upward, and the lifting plate 17 compresses the vertical spring 18 upward. At the same time, the lifting plate 17 also drives the magnetic block 16 and the rod 15 to move upward synchronously, and the rod 15 drives the wedge plate 19 to move upward synchronously. The wedge surface of the wedge plate 19 pushes the inclined surface 11 of the square rod 10 upward. With the cooperation of the wedge surface and the inclined surface 11, the square rod 10 moves to the right, thereby driving the left holding block 12 to move to the right, and the arc groove 6 of the left holding block 12 moves toward the direction of the sample tube 8. At the same time, the left holding block 12 stretches the horizontal spring 13 to the right. When the magnetic block 16 is adsorbed and fixed on the iron plate 14, the sample tube 8 is just fixed between the left holding block 12 and the right holding block 9. Fig.10 As shown, after holding tightly, the worker releases his left hand holding the sample tube 8;

[0039] S3. The worker operates the flow cytometer to analyze the cells in the sample tube 8.

[0040] Among them, it can be seen from step S2 that the worker only needs to push up the pull ring 20 so that the magnetic block 16 is adsorbed and fixed on the iron plate 14, and the sample tube 8 can be fixed between the left clamping block 12 and the right clamping block 9 in a short time, thereby realizing the rapid fixation of the sample tube 8. It can be seen that the sample tube fixing assembly of the present invention is better than the above-mentioned Figure 1~Figure 3 The sample tube fixing assembly shown does not need to screw the adjusting screw 3 twice to fix the sample tube 8, thereby greatly shortening the fixing time of the sample tube 8 and further greatly improving the fixing efficiency of the sample tube 8.

[0041] When the sample tube 8 is to be taken away, the worker only needs to pull the pull ring 20 downward to separate the magnetic block 16 from the iron plate 14. Under the elastic restoring force of the horizontal spring 13, the left clamping block 12 moves to the left, and then the worker can take the sample tube 8 away.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
