Description

Technical Field

[0001] This utility model relates to the field of pipette support technology, specifically an adjustable micropipettes support. Background Technology

[0002] In experiments such as molecular biology, cell culture, and clinical testing, micropipettes are among the most commonly used precision instruments. Traditionally, pipettes are often placed haphazardly on the lab bench, which has several drawbacks: First, pipettes are prone to rolling or slipping, potentially damaging the precision instrument; second, multiple pipettes mixed together are inconvenient to use, affecting experimental efficiency; and third, a fixed placement height may cause inconvenience for experimenters of different heights.

[0003] While some pipette holders exist in the current technology, most are single-function, only capable of simple storage. Some holders, although height-adjustable, use manual knobs, which are cumbersome and difficult to position accurately. Other rotatable holders lack stable positioning mechanisms, making them prone to displacement during operation. In addition, existing holders generally suffer from insufficient protection, and the electric components are susceptible to corrosion from common laboratory liquid splashes, affecting their service life. Therefore, traditional holders can no longer meet the needs of rapid and accurate retrieval and require improvement. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable micropipette holder to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable micropipette holder, including a holder base, a drive motor fixedly connected to the upper end face of the holder base, an electric telescopic rod fixedly connected to the output end of the drive motor, a plug block fixedly connected to the top end of the electric telescopic rod, a pipette placement rack detachably mounted on the plug block, and a protective component for sealing the electric telescopic rod on the pipette placement rack.

[0006] The protective component includes a protective cylinder fixedly connected to the lower end face of the pipette placement rack, and the electric telescopic rod is disposed inside the protective cylinder.

[0007] The upper end face of the support base is fixedly connected to a sleeve that is adapted to the protective cylinder, and the protective cylinder is slidably connected inside the sleeve.

[0008] The bracket base is fixedly connected to a placement seat, and the lower end face of the placement seat is fixedly connected to several anti-slip pads.

[0009] The upper end face of the plug block is provided with a slot, and the lower end face of the pipette holder is fixedly connected with a plug rod that matches the slot.

[0010] The slot has a limiting groove inside, and the bottom of the insertion rod is fixedly connected to a limiting block that matches the limiting groove.

[0011] The pipette placement rack has several placement slots, and a gripper is fixedly connected to the upper end face of the pipette placement rack.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention achieves convenient storage and retrieval of pipettes through an innovative support structure. Specifically, the support base is made of high-strength engineering plastic or aluminum alloy with an anti-corrosion treatment to ensure long-term stable use in laboratory environments. The drive motor's rotation angle can be precisely controlled to meet the precise positioning requirements of different experimental scenarios.

The electric drive method enables precise adjustment of height and angle, which is more convenient and efficient than traditional manual adjustment. The pipette rack adopts a split structure, which can be quickly replaced according to the size and specifications of different pipette models, greatly improving the flexibility of use. Each placement slot is embedded with a shock-absorbing silicone pad, which can not only securely fix the pipette but also effectively prevent scratches on the instrument surface. This makes the support particularly suitable for high-throughput experimental environments that require frequent use of various sizes of pipettes, significantly improving experimental efficiency and reducing the workload of operators.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: an adjustable micropipette holder, including a holder base 1, a placement seat 13 fixedly connected to the holder base 1, and several anti-slip pads 14 fixedly connected to the lower end face of the placement seat 13. The holder base 1 is the basic support platform of the entire holder, made of metal or high-strength engineering plastic. The placement seat 13 can be used to temporarily store small items such as pipette tips and spare pipette tip boxes, improving space utilization. The anti-slip pads 14 are made of rubber and have shock absorption function to prevent the holder from accidentally shifting when operating the pipette, which is especially suitable for smooth laboratory surfaces. A drive motor 2 is fixedly connected to the upper end face of the holder base 1, and an electric telescopic rod 3 is fixedly connected to the output end of the drive motor 2. A plug block 4 is fixedly connected to the top end of the electric telescopic rod 3, and a pipette placement rack 5 is detachably installed on the plug block 4.

[0022] Specifically, the drive motor 2 is connected to the electric telescopic rod 3 through the output shaft, which can drive the pipette holder 5 to rotate horizontally. This allows the experimenter to quickly adjust the orientation of the pipette in different operating positions, such as left-handed / right-handed or when multiple people are using it. When the drive motor 2 is in use, it can also be connected to an external speed controller or a preset program to achieve low-speed and smooth rotation and prevent the pipette from falling off due to inertia or stopping at a fixed point. Some high-end models can integrate an angle sensor to achieve precise indexing and positioning.

[0023] The electric telescopic rod 3 can raise and lower the pipette holder 5 through its telescopic movement to adapt to different laboratory bench heights or operator height requirements, such as switching between sitting and standing positions. It can be driven by a stepper motor or servo drive, and has a self-locking function to maintain hovering stability. It can also be equipped with scale markings or a linked digital display screen to accurately reproduce commonly used heights.

[0024] The pipette holder 5 has several placement slots 6, and a gripper 15 is fixedly connected to the upper end of the pipette holder 5. The placement slots 6 are fitted with elastic clips or sponge pads to accommodate different pipette models and prevent scratching the outer casing. The slots are arranged in a circular pattern around the pipette holder 5 for easy and quick placement and removal. The gripper 15 is covered with a non-slip texture or soft rubber to facilitate lifting the entire pipette holder 5 with one hand for transfer.

[0025] The upper surface of the connector block 4 has a slot 7, and the lower surface of the pipette holder 5 is fixedly connected to a rod 9 that matches the slot 7. The slot 7 has a limiting groove 8 inside, and the bottom of the rod 9 is fixedly connected to a limiting block 10 that matches the limiting groove 8. Specifically, the slot 7 and the rod 9 work together to achieve quick alignment and installation. The limiting groove 8 and the limiting block 10 prevent relative rotation between the pipette holder 5 and the connector block 4 when the pipette holder 5 rotates, ensuring effective power transmission from the drive motor 2. The limiting block 10 is made of wear-resistant nylon to reduce wear over long-term use and ensure optimal performance.

[0026] The pipette holder 5 is equipped with a protective component for enclosing the electric telescopic rod 3. This protective component includes a protective cylinder 11 fixedly connected to the lower end face of the pipette holder 5. The electric telescopic rod 3 is housed inside the protective cylinder 11. A sleeve 12, adapted to the protective cylinder 11, is fixedly connected to the upper end face of the support base 1. The protective cylinder 11 is slidably connected inside the sleeve 12. The protective cylinder 11 completely encloses the electric telescopic rod 3, preventing corrosion caused by splashing of experimental liquids such as acids, alkalis, and organic solvents. It also reduces dust ingress, minimizing its impact on the lifespan of the drive motor 2. A linear bearing is embedded in the inner wall of the sleeve 12, allowing for smoother raising and lowering of the protective cylinder 11, reducing the load on the electric telescopic rod 3, and extending its service life.

[0027] Furthermore, the support can also integrate a weight sensor to monitor the pipette placement and removal status, or be equipped with LED lighting strips to assist in darkroom operations.

[0028] Working Principle: When in use, the bracket must first be placed securely. During operation, the height of the pipette holder 5 can be adjusted by the lifting and lowering movement of the electric telescopic rod 3. The drive motor 2 rotates the entire bracket to adjust its direction. Specifically, during operation, the extension or retraction of the electric telescopic rod 3 can synchronously raise and lower the top insertion block 4 and the pipette holder 5. Simultaneously, the protective cylinder 11 slides along the sleeve 12. The drive motor 2, through its output shaft, can rotate the electric telescopic rod 3. The limiting groove 8 within the insertion block 4 and the limiting block 10 of the insertion rod 9 ensure that the pipette holder 5 also rotates accordingly. The pipette can be directly placed in the placement slot 6 for easy retrieval. When adjustments are needed, the quick-release design of the insertion rod 9 and slot 7 facilitates the replacement of the pipette holder 5 to meet different usage requirements. The anti-slip pad 14 at the bottom of the bracket base 1 ensures the overall stability of the bracket, making it suitable for various experimental scenarios.
