Description

Technical Field

[0001] The utility model relates to the technical field of cell identification pipettes, and particularly relates to a cell identification pipette with a heat preservation structure. Background Technique

[0002] A pipette, also called a pipetting gun, is a measuring tool that transfers liquid from an original container to another container within a certain range of measuring ranges. It is widely used in the fields of biology, chemistry, etc. Cell identification experiment is a commonly used experimental method in biomedical research, which is used to detect and analyze the morphological, quantitative, functional and structural characteristics of cells. A pipette is needed to transfer samples in cell identification experiments.

[0003] At present, although the cell identification pipette can conveniently transfer sample liquids, the general pipette does not have a heat preservation outer shell structure. When the transfer time is long, the temperature of the sample may change, which may affect the experimental results. Based on this, we propose an improvement on a cell identification pipette with a heat preservation structure. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a cell identification pipette with a heat preservation structure, which can effectively solve the technical problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A cell identification pipette with a heat preservation structure includes a heat preservation outer shell and a pipette body. The heat preservation outer shell includes an outer shell one and an outer shell two. A heat preservation sleeve is movably sleeved between the outer shell one and the outer shell two. The heat preservation sleeve is movably sleeved on the outer end of the pipette body. Bottom supports are fixedly connected to the inner walls near the lower end surfaces between the outer shell one and the outer shell two. The heat preservation sleeve is arranged above the bottom supports. A rectangular opening is formed on the outer wall of the heat preservation sleeve. A viewing window is fixedly arranged on the outer wall of the outer shell one.

[0007] As a further scheme of the utility model, sleeve blocks and fixing blocks are respectively fixedly connected to the outer walls on both sides of the outer shell one and the outer shell two. An installation groove is formed in the sleeve block. An installation block is fixedly connected to one side of the fixing block. The installation block is slidably sleeved in the installation groove.

[0008] As a further scheme of the utility model, a clamping groove is formed at the upper end of the installation block. A sleeve is fixedly connected to the upper end of the sleeve block. A screw rod is threadedly sleeved on the sleeve. A clamping block is rotatably sleeved at the lower end of the screw rod. The clamping block is slidably sleeved in the clamping groove.

[0009] As a further scheme of the utility model, the clamping block is slidably sleeved in the sleeve, and the clamping block penetrates through the sleeve block and extends into the installation groove.

[0010] As a further solution of the present utility model, the contact surface between the lower end of the clamping block and the mounting block is of an inclined surface structure, and the outer walls on both sides of the clamping block are slidably attached to the inner wall of the clamping groove.

[0011] As a further solution of the present utility model, the two base trays are made of two identical semi-circular structures, and the inner diameters of the two base trays are smaller than the outer diameter of the heat-insulating sleeve.

[0012] As a further solution of the present utility model, the front area of the rectangular opening is larger than the front area of the viewing window, which is larger than the front area of the display window of the pipette body, and the heat-insulating sleeve is made of heat-insulating material.

[0013] The beneficial effects of the present utility model are as follows:

[0014] By setting the heat-insulating outer shell and the heat-insulating sleeve structure, the heat-insulating sleeve is fixed by the heat-insulating outer shell, and the pipette body is insulated by the heat-insulating sleeve, which can effectively improve the temperature stability of the sample liquid during transfer, avoid large temperature changes, and affect the experimental results;

[0015] By sleeving the mounting block in the mounting groove and using the clamping block to sleeve the clamping groove to fix the mounting block, the disassembly and assembly between the first outer shell and the second outer shell can be conveniently realized, so that the heat-insulating sleeve structure can be replaced at any time according to needs, improving the heat-insulating effect. Moreover, the contact surface between the lower end of the clamping block and the upper end of the mounting block is of an inclined surface structure. As the screw is tightened, the clamping block presses the mounting block to move towards the sleeve block side, so that the first outer shell and the second outer shell can be fastened together, enabling the heat-insulating sleeve to be tightly pressed on the outer wall of the pipette, avoiding gaps and affecting the heat-insulating effect, and having practicability.

[0023] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As Figure 1-6 shown, a cell identification pipette with a heat-insulating structure includes a heat-insulating outer shell 1 and a pipette body 2. The heat-insulating outer shell 1 includes an outer shell one 11 and an outer shell two 12. A heat-insulating sleeve 3 is movably sleeved between the outer shell one 11 and the outer shell two 12. The heat-insulating sleeve 3 is movably sleeved outside the pipette body 2. Bottom supports 13 are fixedly connected to the inner walls of the outer shell one 11 and the outer shell two 12 near the lower end surface. The heat-insulating sleeve 3 is arranged above the bottom support 13. A rectangular opening 31 is formed in the outer wall of the heat-insulating sleeve 3. A window 14 is fixedly arranged on the outer wall of the outer shell one 11.

[0025] In this embodiment, sleeve blocks 15 and fixed blocks 16 are respectively fixedly connected to the outer walls on both sides of the outer shell one 11 and the outer shell two 12. An installation groove 19 is formed in the sleeve block 15. One side of the fixed block 16 is fixedly connected with a mounting block 17. The mounting block 17 is slidably sleeved in the installation groove 19. By sliding the mounting block 17 in the installation groove 19, the outer shell one 11 and the outer shell two 12 can be mutually butted.

[0026] In this embodiment, a card slot 18 is formed at the upper end of the mounting block 17. A sleeve 110 is fixedly connected to the upper end of the sleeve block 15. A screw 111 is threadedly sleeved on the sleeve 110. The lower end of the screw 111 is rotatably sleeved with a clamping block 112. The clamping block 112 is slidably sleeved in the card slot 18. By rotating the screw 111, the clamping block 112 can be driven to descend and be sleeved in the card slot 18.

[0027] In this embodiment, the clamping block 112 is slidably sleeved on the sleeve 110, and the clamping block 112 penetrates through the sleeve block 15 and extends into the installation groove 19. The lifting movement of the clamping block 112 is limited by the sleeve 110 to prevent it from rotating along with the screw 111.

[0028] In this embodiment, the contact surface between the lower end of the clamping block 112 and the mounting block 17 is an inclined surface structure. The outer walls on both sides of the clamping block 112 are slidably attached to the inner wall of the clamping groove 18. When the clamping block 112 descends, it can press the mounting block 17 to slide towards the sleeve block 15, so that when the screw 111 is tightened, the sleeve block 15 and the fixed block 16 can be pressed tightly, thereby pressing the outer shell one 11 and the outer shell two 12 tightly.

[0029] In this embodiment, the two bottom brackets 13 are made of two identical semi-circular structures. The inner diameter of the two bottom brackets 13 is smaller than the outer diameter of the heat preservation sleeve 3. The bottom brackets 13 are made of hard rubber blocks, which are mainly used to prevent the heat preservation sleeve 3 from sliding out from below the heat preservation shell 1.

[0030] In this embodiment, the front area of the rectangular opening 31 is larger than the front area of the viewing window 14, which is larger than the front area of the display window of the pipette body 2, facilitating the observation of the display window of the pipette body 2 through the viewing window 14. The heat preservation sleeve 3 is made of heat preservation materials.

[0031] It should be noted that the present utility model is a cell identification pipette with a heat preservation structure. When in use, the sample liquid is sucked into the liquid storage tube of the pipette through the pipette body 2 and stored, and then transferred; before transferring the solution, the heat preservation sleeve 3 is sleeved on the outer wall of the pipette body 2 from the bottom upwards. It should be noted that the heat preservation sleeve 3 completely or at least more than half covers the liquid storage tube, and the display window of the pipette body 2 is located within the visible area of the rectangular opening 31. Then, first, the outer shell one 11 is buckled to the outer end of the heat preservation sleeve 3 so that the viewing window 14 is aligned with the display window of the pipette body 2. Then, the outer shell two 12 is closed on the other side of the heat preservation sleeve 3. The mounting block 17 is sleeved in the mounting groove 19, and then the screw 111 is rotated to drive the clamping block 112 to descend and fit into the clamping groove 18. As the clamping block 112 gradually presses down, the mounting block 17 is gradually pressed into the inner side of the mounting groove 19, so that the outer shell one 11 and the outer shell two 12 can be tightly pressed on the outer end of the heat preservation sleeve 3, thus completing the installation.
