Description

Technical Field

[0001] The utility model relates to the technical field of instrument detection, in particular to a sample fixing structure used for instrument detection and analysis. Background Art

[0002] Biological experiment refers to the process of purposefully observing and studying the structure and life activity phenomena of organisms that are difficult to observe under normal circumstances by using certain instruments, materials and drugs and scientific methods under specific environmental conditions.

[0003] In biological experiments, detection instruments are often used to analyze reagents, and most of the reagents are stored in test tubes. When the reagents are detected, the operator holds the detection instrument and the test tube in his hands respectively, and extends the probe of the detection instrument into the test tube. When the reagent in a test tube is detected, the detected test tube is put back in place, and the untested test tube is picked up, and the above steps are repeated. The reagent is tested again using the detection instrument, and the test tube is fixed manually. This leads to the following deficiencies in the detection of reagents: the test tube is limited manually, which requires the operator's hand to always hold the test tube. If the arm loses strength or accidentally overturns the test tube, it will cause the test tube to fall off and break; and the test tube is limited manually, which makes it impossible to simultaneously limit multiple test tubes during the detection of the reagent, which not only increases the operator's workload, but also affects the efficiency of reagent detection. Utility Model Content

[0010] Preferably, a clamping plate is fixedly mounted on the connecting rod 1 and the connecting rod 2, and a locking bolt matched with the fixed cylinder and the movable cylinder is threadedly connected on the clamping plate.

[0011] Preferably, the fixed plate is vertically arranged corresponding to the movable plate, and the clamp is a concave or arc-shaped structure adapted to the sample tube.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4 A sample fixing structure for instrument detection and analysis includes a base 1 and a clamp 14 for clamping a sample test tube. A symmetrically arranged fixing cylinder 3 is fixedly mounted on the base 1. A slider 6 is connected to the base 1 through a moving part. The clamp 14 is arranged on the base 1 to clamp the test tube, so that the reagent in the test tube does not need to be manually supported during detection, thereby ensuring the stability of the test tube during detection and effectively avoiding the test tube from tipping over due to manual support of the test tube;

[0022] The moving part includes a motor 2 fixedly mounted on the base 1, and a bidirectional screw 4 is fixedly connected to the output end of the motor 2. After the motor 2 is powered on, it can drive the bidirectional screw 4 to rotate on the base 1. This technical solution is a prior art and will not be elaborated on here. Two matching nuts 5 are provided on the sliding sleeve of the bidirectional screw 4, and a connecting rod 7 is movably installed on the nut 5, and a slider 6 is provided on the connecting rod 7;

[0023] The bidirectional screw rod 4 is arranged horizontally, and a long hole for guiding the slider 6 is provided on the base 1. The two ends of the connecting rod 7 are respectively connected with the nut 5 and the slider 6 pin. The long hole guides the slider 6, thereby limiting the moving direction of the nut 5.

[0024] The slider 6 is integrally connected with a connecting plate 8, and a moving cylinder 9 symmetrically arranged and corresponding to the fixed cylinder 3 is fixedly mounted on the connecting plate 8. The fixed cylinder 3 and the moving cylinder 9 are a circular structure with one side and an open top, and the connecting plate 8 and the slider 6 extend to the upper end position outside the base 1;

[0025] A connecting rod 10 is placed in the fixed cylinder 3, and a fixed plate 12 is integrally connected between two corresponding connecting rods 10. A connecting rod 2 11 is placed in the movable cylinder 9, and a movable plate 13 is integrally connected between two corresponding connecting rods 2 11. According to the specifications of the fixed plate 12 and the movable plate 13, multiple clamps 14 can be installed, so that the multiple clamps 14 can simultaneously limit the position of multiple test tubes, thereby making the reagent detection faster and more efficient.

[0026] A clamping plate 15 is fixedly installed on the connecting rod 10 and the connecting rod 2 11, and a locking bolt adapted to the fixed cylinder 3 and the movable cylinder 9 is threadedly connected to the clamping plate 15. A clamp 14 is respectively arranged on the fixed plate 12 and the movable plate 13. The fixed plate 12 and the movable plate 13 are arranged vertically correspondingly. The clamp 14 is a concave and arc-shaped structure adapted to the sample test tube.

[0027] As a supplementary explanation, before clamping the test tube, the specifications of the clamp 14 are selected according to the specifications of the test tube, so that the clamp 14 can limit the cylindrical or U-shaped test tube, and the connecting rod 10 and the connecting rod 2 11 can be quickly installed through the fixed cylinder 3 and the movable cylinder 9, thereby increasing the adaptability of the fixing device.

[0028] The functional principle of the utility model can be explained through the following operation modes:

[0029] Place the sample to be tested in a test tube, and select the specifications of the fixture 14 according to the specifications of the test tube;

[0030] When the test tube is a rectangular parallelepiped structure, the fixture 14 is selected to be a concave structure;

[0031] When the test tube is a tubular structure, the clamp 14 is selected to be an arc-shaped structure;

[0032] Lift the connecting rod 10 so that when the connecting rod 10 extends into the fixing tube 3, the fixing plate 12 and the clamp 14 are driven to move synchronously, and the connecting plate 8 and the fixing tube 3 are connected by a locking bolt;

[0033] Lift the second connecting rod 11 so that when the second connecting rod 11 extends into the moving cylinder 9, it drives the moving plate 13 and the clamp 14 on the other side to move synchronously, and use the locking bolt to connect the connecting plate 8 and the moving cylinder 9;

[0034] Repeat the above steps to install two sets of corresponding clamps 14 at the designated positions;

[0035] Place the test tubes containing reagents in the fixture 14 in the fixed plate 12;

[0036] The output end of the motor 2 drives the bidirectional screw 4 to rotate, and the bidirectional screw 4 drives the two nuts 5 to move toward or in opposite directions when rotating;

[0037] When the two nuts 5 move toward each other, they pull the connecting rod 7. The position difference generated when the connecting rod 7 is pulled can resist the slider 6, so that the slider 6 drives the connecting plate 8 to move when sliding in the long hole. When the connecting plate 8 moves, it drives the moving cylinder 9, the moving plate 13, and the clamp 14 to gradually approach the fixed plate 12, so that the two corresponding clamps 14 can simultaneously clamp multiple test tubes;

[0038] The multiple reagents on the base 1 are detected by a detection instrument.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
