Description

Technical Field

[0001] The utility model relates to the technical field of electric pipettes, and more specifically, to a fixing device for an electric pipette. Background Art

[0002] A pipette, also known as a pipette gun, is an instrument used to transfer liquids quantitatively. An electric pipette is a type of pipette. The working principle of an electric pipette is to use an electric current to drive the spring to expand and contract, thereby causing the piston to move up and down to discharge or absorb liquid. The biggest advantage of electric pipettes is that they have high repeatability and accuracy. They can automatically transfer liquids according to settings, saving manpower. They are suitable for laboratories with frequent daily pipetting. When an electric pipette needs to be temporarily placed, a fixture is required for placement.

[0003] The utility model patent with patent application number 202121627393.0 discloses a fixing device for an electric pipette, including a pipette body; a joint is provided on the bottom inner wall of an outer box, and a sliding hole is opened on the inner wall of one side of the outer box; a placement slot block, the placement slot block is movably plugged into the interior of the outer box, and an upper inclined surface block is fixedly connected to one side of the placement slot block; the pipette body is placed in the placement slot block, and the pipette body is pressed downward so that the pipette body is plugged into the joint, the lower inclined surface block clamps the upper inclined surface block to keep the body and the joint from separating, the outer rod plate is pulled to drive the lower inclined surface block to no longer clamp the upper inclined surface block, and the compression spring separates the pipette body and the joint, so that the pipette body can be easily removed.

[0004] However, in actual use, since the placement slot block is fixedly connected to the outer box, when it needs to be temporarily moved elsewhere for use, the fixing device needs to be moved as a whole, and the fixing device is connected to a power source, which is inconvenient to move, resulting in a limited range of use of the fixing device.

When the placement slot block 5 needs to be placed back, first slide the placement slot block 5 through the slide groove 3 and the slider 4 of the connecting frame 2 and install it back into the fixing device.

[0031] Reference Figure 4As shown, the movable mechanism includes a plurality of springs 7, and the plurality of springs 7 are all arranged inside the base frame 23, and one end of the plurality of springs 7 are all connected to the connecting plate 6. A hole slot 9 is provided on one side of the connecting frame 2, and a hole slot 2 10 is provided on one side of the placement slot block 5. The position of the hole slot 19 is lower than the hole slot 2 10, and a latch 11 is movably provided on the inner wall of the hole slot 19. The latch 11 is passed through the hole slot 19 of the connecting frame 2 and then through the hole slot 2 10, and at the same time, the placement slot block 5 is pressed down and the spring 7 is squeezed, so that the connector 8 contacts the bottom of the pipette body 22, and the pipette body 22 is charged.

The connecting tube 13 rotates left and right along the connecting block 12, and the plug plate 14 and the plug plate 2 16 rotate along the rotating rod 15.

[0037] The working principle of the utility model is as follows: first, the staff member passes the plug 11 through the hole slot 1 9 of the connection frame 2 and then through the hole slot 2 10, and at the same time presses down the placement slot block 5 and squeezes the spring 7, so that the connector 8 contacts the bottom of the pipette body 22, and charges the pipette body 22. When charging is not needed, first pull out the plug 11, and the spring 7 drives the placement slot block 5 to reset, so that the connector 8 leaves the pipette body 22 to cancel charging. When the pipette body 22 needs to be used in other positions, the rotating plug plate 14 and the plug plate 2 16 are rotated out of the stopper 17. Cancel the limit on the placement slot block 5, then remove the placement slot block 5 from the connecting frame 2 separately, then rotate the plug plate 2 16, and rotate it with the rotating rod 15, so that the plug plate 2 16 contacts the plane to support the placement slot block 5. When the placement slot block 5 needs to be placed back, first slide the placement slot block 5 through the slide groove 3 and the slider 4 of the connecting frame 2, and install it back into the fixing device, then rotate the plug plate 1 14 and the plug plate 2 16 through the connecting tube 13, and snap the plug plate 2 16 into the slot of the stopper 17 to limit the position of the placement slot block.
