Description

Technical Field

[0001] This utility model relates to an elastic snap-on vertically suspended pipette device, belonging to the field of experimental equipment. Background Technology

[0002] A volumetric pipette is a widely used glass volumetric instrument in laboratories for accurately transferring a certain volume of solution. It is a measuring instrument, and there are single-mark volumetric pipettes and graduated volumetric pipettes. The volume specifications range from 0.1 mL to 100 mL. The shape can be a straight tube or a tube that is bulging in the middle and thin at both ends. The upper neck of the tube is engraved with graduation marks, and the lower end is a pointed tip.

[0003] As a fundamental tool, the correct use, cleaning, and storage of pipettes have a significant impact on the accuracy of experimental data and quantitative analysis. After use, pipettes need to be cleaned and stored on a shelf to avoid damage from impacts or contamination from contact with surrounding items. Residual liquid in the pipettes after use should also be kept away from contaminating surrounding items or affecting subsequent solution extraction.

[0004] Currently, most pipettes are stored in trapezoidal, disc-shaped, or vertical configurations, which present problems such as easy contamination, easy damage, large space occupation, inconvenience in use, difficulty in draining residual water after cleaning, and easy bacterial growth. Meanwhile, large-capacity pipettes have problems such as a high center of gravity, instability, and lack of a dedicated drainage structure. Utility Model Content

[0005] The technical problem to be solved by this utility model is that existing pipettes are easily contaminated and damaged when placed, are inconvenient to use, are not easy to drain water, and are unstable when placed.

The end of the crossbar is rotatably connected to the rotating sleeve, and turning the rotating sleeve can drive the crossbar to move upward along the adjusting rod axis.

[0010] Furthermore, the end of the crossbar in the above-mentioned device is provided with a through hole, the axis of the through hole is perpendicular to the length direction of the crossbar, the rotating sleeve is a T-shaped structure, and the small end of the rotating sleeve passes through the through hole and is in clearance fit with the through hole.

The crossbar 3 passes through the strip-shaped through holes 11 along the width direction of the U-shaped opening. Several elastic snaps 6 are provided on the crossbar 3 at intervals. The adjustment component can adjust the distance between the crossbar 3 and the upper end of the bracket 1. Those skilled in the art will understand that this device mainly includes a support 1, a crossbar 3, and an adjustment assembly. The support 1 is used for support and fixation, and is preferably made of a material with a certain strength, such as steel or composite material. To facilitate the setting of the crossbar 3, it is actually preferred that a U-shaped opening is opened on one side wall of the support 1, and strip-shaped through holes 11 are opened on both sides of the U-shaped opening, so that the crossbar 3 passes through the strip-shaped through holes 11 along the width direction of the U-shaped opening, and both ends extend out of the support 1. Several elastic buckles 6 are provided at intervals on the crossbar 3. The elastic buckles are made of plastic or metal material with elastic recovery force, and are in the shape of a circular or elliptical arc structure with an opening, or two elastic clips made of plastic or metal material with elastic recovery force are fixed on the crossbar 3 to form a groove structure with an opening, which is used to clamp the holding space of the pipette. The diameter of the clamping space is slightly smaller than the diameter of the pipette, so as to use elasticity to achieve a stable clamping of the pipette. The inner wall is provided with a silicone anti-slip layer to prevent the pipette from slipping and avoid scratching. The adjustment mechanism is used to adjust the distance between the crossbar 3 and the upper end of the bracket 1 to accommodate pipettes of different lengths. Ideally, the bracket 1 can be fitted with anti-slip rubber pads at the four corners to prevent slippage. To accommodate different pipette sizes, the elastic clips 6 are spaced 1-3cm apart and arranged in a row for easy categorization and storage. This structure requires no drilling and can be placed directly on a lab bench, making it easy to move and suitable for laboratories where wall mounting is inconvenient. Alternatively, it can be fixed to a lab wall with expansion screws at a height of 1.3 meters from the ground. The elastic clips 6 are spaced 3cm apart to prevent pipettes from colliding. In use, the pipette tip is hung vertically upwards for convenient and quick access and return, effectively reducing contamination and damage while saving bench space.
