Abstract
Description
An adjustable pipette holder Technical Field
[0001] This utility model relates to the field of pipette holder technology, and in particular to an adjustable pipette holder. Background Technology
[0002] In biochemistry and molecular biology laboratories, pipettes are commonly used experimental tools. Pipettes are currently the most frequently used tool for quantitative liquid transfer in biomedical research, commonly used for transferring small or trace amounts of liquid in the laboratory. They can transfer liquid from one container to another within a certain volume range, enabling simple and rapid liquid transfer. In the laboratory, pipettes are used frequently, and depending on the experiment, multiple pipettes of different capacities are usually used. Therefore, pipettes of different capacities need to be stored separately; generally, laboratories use dedicated pipette racks to store pipettes.
[0003] However, existing pipette holders are usually fixed, with pipettes maintained at a fixed height and angle. This prevents flexible adjustment of the pipette's position and angle according to experimental needs, leading to inconvenience and poor ease of use in experiments. Especially when frequent pipette changes or adjustments are required, the inability of existing pipette holders to adjust the pipettes placed on them results in low pipette usage efficiency, consequently reducing experimental efficiency. Summary of the Invention
[0004] To address the technical problem that existing technologies cannot flexibly adjust the position and angle of the pipette according to experimental needs, resulting in inconvenience and low efficiency in the use of the pipette, and consequently low experimental efficiency, this utility model provides the following technical solution.
[0005] This utility model discloses an adjustable pipette holder, comprising a base and a column fixedly connected to the base. A lifting column is slidably connected to the column. The lifting column includes a column body slidably connected to the column and a movable block located on one side of the lower part of the column body. The column has a lifting groove slidably connected to the column body and a movable groove located on one side of the lifting groove for the movable block to slide up and down. An adjusting component is fixedly connected to the movable block. The adjusting component includes a telescopic sleeve with a spring on its outer periphery fixedly connected to the movable block. A locking block is fixedly connected to the other end of the telescopic sleeve. Positioning grooves matching the locking block are provided on both sides of the movable groove. A turntable is rotatably connected to the upper part of the column body. Several support arms are provided on the outer periphery of the turntable. A fixing clip for holding a pipette is provided at the end of each support arm away from the turntable.
[0006] As a further technical solution, the locking block has a groove on the side facing the movable block that is fixedly connected to the telescopic sleeve and matches the shape of the movable block.
[0007] As a further technical solution, the lifting groove is provided with a number of limiting slide grooves, and the outer wall of the column is provided with a number of limiting slide columns that match the limiting slide grooves.
[0008] As a further technical solution, the upper end of the column is provided with a threaded end, and the threaded end is threadedly connected with a locking nut.
[0009] As a further technical solution, the fixing clamp includes a fixing plate fixedly connected to the support arm and a hanging groove located at the upper end of the fixing plate, and a clamping ring is provided at the lower end of the fixing plate.
[0010] As a further technical solution, the clamping ring is a ring structure made of elastic material.
[0011] The beneficial effects of this invention are as follows: The column is slidably connected to a lifting column, which is connected to an adjusting component. This adjusting component effectively positions the column and lifting column longitudinally, allowing the lifting column to move up and down relative to the column. This enables flexible adjustment of the height of the lifting column and pipette according to experimental needs. Several fixing clamps are connected to the upper end of the column via a turntable. The turntable can drive the fixing clamps and pipette to rotate 360 degrees, thus allowing flexible adjustment of the angle between the pipette and the experimenter according to experimental needs, improving the convenience and efficiency of pipetting, and consequently enhancing the convenience and efficiency of experimental operations.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0020] As shown in Figure 1, this utility model discloses an adjustable pipette holder, comprising a base 1 and a column 2 fixedly connected to the base 1. The base 1 has a disc-shaped structure for stable support on an experimental table. The column 2 is vertically mounted on the upper part of the base 1. A lifting column 3 is slidably connected to the column 2, allowing the lifting column 3 to move up and down relative to the column 2. The upper part of the lifting column 3 is provided with a fixing clip 7 for holding the pipette. The fixing clip 7 can rotate horizontally, thereby allowing adjustment of the height and angle of the pipette.
[0021] As shown in Figures 2, 3, and 4, in a preferred embodiment, the lifting column 3 includes a column body 301 slidably connected to the column 2. The column body 301 can move up and down relative to the column 2. The column 2 is provided with a lifting groove 201 slidably connected to the column body 301. The inner wall of the lifting groove 201 is provided with a plurality of limiting grooves 202, and the outer wall of the column body 301 is provided with a plurality of limiting sliding columns 302 that match the limiting grooves 202. In this embodiment, there are two limiting grooves 202 and two limiting sliding columns 302, thereby ensuring that the column body 301 can move up and down stably relative to the column 2 and preventing it from deviating during the lifting process.
[0022] In a preferred embodiment, a movable block 303 is fixedly provided on one side of the lower part of the column 301. The movable groove 203 on one side of the lifting groove 201 allows the movable block 303 to slide up and down. An adjusting component 4 is fixedly connected to the movable block 303. The adjusting component 4 can lift the column 301 through the movable block 303, so that the lifting column 3 can move up and down. The adjusting component 4 can be locked on the outside of the column 2. Thus, the adjusting component 4 can keep the column 2 and the lifting column 3 relatively fixed.
[0023] In a preferred embodiment, the adjusting component 4 includes a telescopic sleeve 404 fixedly connected to the movable block 303. A spring 405 is provided on the outer periphery of the telescopic sleeve 404. A locking block 401 is fixedly connected to the other end of the telescopic sleeve 404 away from the movable block 303. A pull ring 402 is provided on the outer side of the locking block 401. Positioning grooves 204 matching the locking block 401 are provided on both sides of the movable groove 203. When adjusting the height of the column 301, pull the pull ring 402 horizontally outward, and the locking block 401 will move outward. Pull the locking block 401 up or down, and the locking block 401 will drive the telescopic sleeve 404 and the movable block 303 to move up or down, thereby moving the column 301 up or down, thus adjusting the height of the pipette at the top of the lifting column 3. After adjusting the height of the column 301, hold the column 301 to stabilize it, and then release the locking block 401. Under the action of the spring 405, the locking block 401 will press against the positioning groove 204, thereby keeping the lifting column 3 and the column 2 relatively fixed.
[0024] In a preferred embodiment, the locking block 401 has a groove 403 on the side facing the movable block 303, and the telescopic sleeve 404 is fixedly connected in the groove 403. The shape of the inner wall of the groove 403 matches the shape of the movable block 303, and the locking block 401 is more stable after it is pressed against the positioning groove 204.
[0025] As shown in Figures 1 and 5, in a preferred embodiment, a turntable 5 is rotatably connected to the upper part of the column 301. The turntable 5 can rotate 360 degrees relative to the column 301, thereby adjusting the angle of the pipette relative to the experimenter. The turntable 5 is rotatably connected to the outer wall of the column 301 via bearings. Several support arms 6 are provided on the outer periphery of the turntable 5. In this embodiment, there are six support arms 6, and each support arm 6 has a fixing clip 7 for holding the pipette at its end away from the turntable 5. The upper end of the column 301 has a threaded end 304 located above the turntable 5, and a locking nut 8 is threadedly connected to the threaded end 304. Rotating the support arms 6 causes the turntable 5 to rotate, which in turn causes the pipette placed on the fixing clip to rotate. After adjusting the angle of the pipette, tightening the locking nut 8 causes it to press downward against the turntable 5, preventing the turntable 5 from rotating erratically.
[0026] In a preferred embodiment, the fixing clip 7 includes a fixing plate 701 fixedly connected to the support arm 6 and a hanging groove 702 located at the upper end of the fixing plate 701. The lower end of the fixing plate 701 is provided with a clamping ring 703. The clamping ring 703 is a ring-shaped structure made of elastic material. The side of the clamping ring 703 away from the fixing plate 701 has an opening for the pipette handle to be inserted and clamped. The elastic material can be a metal spring or a plastic elastic material, and this utility model does not make any particular limitation on it.
[0027] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
