Description

Technical Field

[0001] This utility model relates to the field of experimental instrument technology, specifically to a cell preservation solution addition mechanism. Background Technology

[0002] There are many types of experimental instruments, which are widely used in various scientific research and experimental fields. Cell preservation solution is a liquid used to preserve cells obtained after sampling from living organisms. It is a commonly used consumable experimental instrument and is mainly used in cell detection technology.

[0003] Currently, existing technologies use pipettes to extract cell preservation solution and add it to test tubes or beakers. However, pipettes lack a fixing structure, requiring the hand to maintain the suction posture after aspiration to prevent the cell preservation solution from dripping out of the pipette. Therefore, a cell preservation solution adding mechanism is proposed. A compression spring pushes a pin rod to move through a limiting ring, inserting the pin rod into a locking hole. This fixes the upward-moving collar, preventing the cell preservation solution from dripping out of the conical tube head and the suction tube. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a cell preservation solution adding mechanism. A compression spring pushes a pin rod to move through a limiting ring, inserting the pin rod into a locking hole. This fixes the upward-moving collar, preventing the cell preservation solution from dripping from the conical tube head and the suction tube.

[0005] The technical solution adopted by this utility model to solve its technical problem is a cell preservation solution addition mechanism, including a suction tube, a collar sleeved on the outside of the suction tube, an n-shaped connecting rod connected to the top of the collar through a threaded groove, and a piston block connected to the bottom of the n-shaped connecting rod inside the suction tube through a threaded groove.

[0006] A fixing component is provided on one side of the collar. The fixing component includes a cylinder connected to one side of the collar through a threaded groove. A pin is sleeved on one end of the cylinder, and a compression spring is sleeved on the outer side of the pin inside the cylinder.

[0007] By adopting the above technical solution, when the collar moves upward, the piston block moves upward through the n-shaped connecting rod, drawing the cell preservation solution into the suction tube. The compressed spring pushes the pin rod to move, fixing the collar after it has moved up and down.

[0008] Specifically, a limiting ring is fixedly sleeved on the outer side of the cylinder at one end of the compression spring, and a limiting block is connected to the outer end of the pin rod through a threaded groove.

[0009] Specifically, the bottom end of the suction tube is connected to a tapered tube head via a threaded groove.

[0010] Specifically, structural blocks are provided at the bottom and top of both sides of the suction tube, and limit strips are provided on both sides of the suction tube between the structural blocks. Limit grooves are opened on both sides inside the collar, and the limit grooves are sleeved on the outside of the limit strips.

[0011] Specifically, the suction tube has equidistant locking holes on one side that correspond to the locking pin.

[0012] Specifically, a protective tube is provided at the top of the suction tube, and the n-shaped connecting rod passes through the protective tube.

[0013] The beneficial effects of this utility model are:

[0014] The cell preservation solution adding mechanism of this utility model involves inserting the bottom end of a conical tube head into a container containing cell preservation solution, pushing the collar upward to move the piston block upward via an n-shaped connecting rod, thereby drawing the cell preservation solution into the suction tube through the conical tube head. A compression spring pushes the pin rod to move through a limiting ring, so that one end of the pin rod is inserted into the corresponding locking hole, which can fix the collar after it moves upward and prevent the cell preservation solution drawn into the suction tube and the conical tube head from dripping.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] The compression spring pushes the pin rod to move via the limiting ring, inserting the pin rod into the locking hole. This secures the moved collar, preventing the cell preservation solution from dripping from the conical tube head and the aspiration tube. Figure 1-4 As shown, the cell preservation solution adding mechanism of this utility model includes a suction tube 1, a collar 2 sleeved on the outside of the suction tube 1, an n-shaped connecting rod 3 connected to the top of the collar 2 through a threaded groove, and a piston block 4 connected to the bottom of the n-shaped connecting rod 3 inside the suction tube 1 through a threaded groove.

[0023] A fixing component 5 is provided on one side of the collar 2. The fixing component 5 includes a cylindrical body 501 connected to one side of the collar 2 through a threaded groove. A pin rod 502 is sleeved on one end of the cylindrical body 501. A compression spring 503 is sleeved on the outer side of the pin rod 502 inside the cylindrical body 501.

[0024] When in use, when the collar 2 moves upward, it drives the piston block 4 to move upward through the n-shaped connecting rod 3, drawing the cell preservation solution into the suction tube 1. The compression spring 503 pushes the pin rod 502 to move, fixing the collar 2 after it has moved up and down.

[0025] For example, such as Figure 4 As shown, the present invention also includes a limiting ring 504 fixedly sleeved on the outer side of the cylinder 501 at one end of the compression spring 503, and a limiting block 505 connected to the outer end of the pin rod 502 at the outside of the cylinder 501 through a threaded groove.

[0026] During use, the compression spring 503 pushes the pin rod 502 to move through the limiting ring 504. The limiting ring 504 and the limiting block 505 can prevent the pin rod 502 from falling out of the cylinder 501.

[0027] For example, such as Figure 2 As shown, the present invention also includes a tapered tube head 6 connected to the bottom end of the suction tube 1 via a threaded groove.

[0028] When in use, the piston block 4 moves upward and draws the cell preservation solution into the suction tube 1 through the conical tube head 6.

[0029] For example, such as Figure 1 As shown, the present invention also includes structural blocks 7 at the bottom and top of both sides of the suction tube 1, limiting strips 8 on both sides of the suction tube 1 between the structural blocks 7, and limiting grooves 9 on both sides inside the collar 2, the limiting grooves 9 being sleeved on the outside of the limiting strips 8.

[0030] When in use, the limiting strip 8 and the limiting groove 9 can prevent the collar 2 from rotating outside the suction tube 1, and the structural block 7 can prevent the collar 2 from falling off from the outside of the suction tube 1.

[0031] For example, such as Figure 1 As shown, the present invention also includes, on one side of the suction tube 1, there are equidistant locking holes 11 corresponding to the plug rod 502.

[0032] When in use, the opening of the locking hole 11 facilitates the insertion of the end of the pin 502.

[0033] For example, such as Figure 1 As shown, the present invention also includes a protective tube 10 provided at the top of the suction tube 1, and the n-shaped connecting rod 3 passing through the protective tube 10.

[0034] When in use, the protective tube 10 can prevent the n-shaped connecting rod 3 from tilting.

[0035] When using this utility model, the operator holds the suction tube 1 and inserts the bottom end of the conical tube head 6 into the container containing the cell preservation solution. The limiting block 505 pushes the pin rod 502, causing one end of it to move out of the locking hole 11 and the collar 2 to move upward. The upward movement of the collar 2 causes the piston block 4 to move upward through the n-shaped connecting rod 3, thereby drawing the cell preservation solution into the suction tube 1 through the conical tube head 6.

[0036] After the collar 2 moves upward and the cell preservation solution is drawn into the suction tube 1, the limiting block 505 is released, and the compression spring 503 pushes the pin rod 502 to move through the limiting ring 504, so that one end of it is inserted into the corresponding card hole 11, which can fix the collar 2 after it moves upward and prevent the cell preservation solution drawn into the suction tube 1 and the conical tube head 6 from dripping.

[0037] When the collar 2 moves up and down, the limiting grooves 9 on both sides inside the collar 2 slide outside the limiting strip 8, which can prevent the collar 2 from rotating. The structure block 7 can prevent the collar 2 from falling off the suction tube 1. The protective tube 10 can improve the structural stability of the n-shaped connecting rod 3.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
