Description

TECHNICAL FIELD

[0001] The application provides a deformable multifunctional pipette support, and belongs to the field of laboratory equipment. BACKGROUND

[0002] A pipette is the most commonly used experimental equipment in the disciplines of chemistry, biology and medicine. The pipette can be used for the suction and transfer of micro and trace volumes of liquid. The common type is an air displacement pipette, which works on the principle of using an adjustable piston to form a negative pressure to quantitatively suck different volumes of liquid. The pipette is a precision instrument, and different scales correspond to different suction volumes. Multiple pipettes need to be purchased to meet different experimental requirements. In addition, the pipette cannot be placed horizontally or upside down for a long time. Therefore, the pipette is generally placed on a dedicated pipette support. Currently, the commonly used pipette supports are straight plate type and rotary disc type. However, the two types of pipette supports cannot realize shape conversion, cannot overcome the defects of the prior art, and reduce the practicability. Therefore, the application provides a deformable multifunctional pipette support to solve the above problems. SUMMARY

[0003] The application aims to provide a deformable multifunctional pipette support, which realizes the rapid conversion of the pipette support between the straight plate type and the rotary disc type, so as to overcome the defects of the prior art, such as the large space occupied by the straight plate type pipette support, the easy falling and the inconvenience of high temperature and high pressure sterilization, and the inconvenience of rapid positioning and homing of the rotary disc type pipette support.

[0004] To achieve the above-mentioned purpose, the application realizes the technical scheme as follows:

[0005] A deformable multifunctional pipette support, comprising a rotatable base, a prismatic body, a top holding plate, an upper support plate and a middle support plate.

[0006] Further, the rotatable base comprises a base bottom and a base top.

[0007] The base bottom is made of hard plastic with a large specific gravity, so that the center of gravity is located at the base, for stabilizing the entire pipette support. Meanwhile, the bottom of the base bottom is provided with rubber anti-skid protrusions, so as to ensure that the base bottom will not slide randomly.

[0008] The rotating slide rail is embedded in the base bottom and can rotate freely by 360°. The outer side of the rotating slide rail is provided with a rubber ring in close contact. The rubber ring has irregular protrusions to increase the friction force, facilitating finger operation.

[0009] The base top is connected with the base bottom through the rotating slide rail. The center of the upper surface of the base top is provided with a hexagonal recess, which is used for fixing the prismatic body.

[0010] Further, the prismatic body comprises a trapezoidal prism and a bottom support leg.

[0011] The cross-section of the trapezoidal edge block is an isosceles trapezoid. The face containing the lower base of the isosceles trapezoid is the front face, the face containing the upper base is the back face, and the face containing the waist is the connecting face. The connecting faces of the six trapezoidal edge blocks are connected by hinges in sequence. The six trapezoidal edge blocks can be freely unfolded into a flat state or closed into a prism state.

[0012] Each trapezoidal block has three slots located at the top, upper, and middle of the front of the block, respectively, for connecting the top grip plate, the upper support plate, and the middle support plate.

[0013] The first magnetic module is located on the connecting surface on both sides of the trapezoidal prism block. Three first magnetic modules are distributed in sequence on the middle and lower parts of each connecting surface. When the prism-shaped main body is closed into a prism state, the hinges of the first magnetic module work together to tightly fit the six sets of trapezoidal prism blocks, ensuring the stability of the entire prism-shaped main body structure.

[0014] The upper end of the bottom support leg is hinged to the back of the trapezoidal block. After flipping, it forms a triangular support with the trapezoidal block. When the prism-shaped main body is unfolded into a flat state, it can be stably placed on the table.

[0015] Furthermore, the top grip plate includes a grip plate;

[0016] The grip plates are rectangular in shape and consist of six sets.

[0017] The second magnetic modules are located on both sides of the grip plate. Each set of grip plates has two magnetic modules. When the prism-shaped main body is unfolded into a flat state, the grip plates are sequentially attached and connected to ensure overall stability.

[0018] The grip plate has a buckle at the rear end for inserting the grip plate into the slot at the top of the trapezoidal block.

[0019] Furthermore, the upper support plate includes an upper support plate and an upper connecting plate;

[0020] The rear end of the upper support plate is vertically fixed to the upper end of the upper connecting plate. The front end of the upper support plate has an arc-shaped opening to support the main body of the pipette, which is suitable for pipettes of various sizes. The opening is covered with soft rubber to provide cushioning. There is a hole in the middle of the upper support plate to fix the handle of the pipette.

[0021] The upper connecting plate is equipped with an upper buckle for fitting into the slot at the top of the trapezoidal prism block;

[0022] The third magnetic modules are located on both sides of the upper support plate. When the prism-shaped main body unfolds into a flat state, the upper support plate is connected in sequence through the third magnetic modules.

[0023] Furthermore, the central support plate includes a central support plate and a central connecting plate;

[0024] The rear end of the middle support plate and the front end of the middle connecting plate are vertically fixedly connected; the width of the middle support plate is smaller than that of the upper support plate, and the front end of the middle support plate has an arc-shaped opening to support the pipette tip; the opening is covered with soft rubber to provide cushioning.

[0025] A central buckle is fixed on the central connecting plate for fitting into the slot in the middle of the trapezoidal prism block.

[0026] The technical effects of the present invention are as follows:

[0027] 1. The provided deformable multi-functional pipette holder, in its straight plate form, facilitates quick positioning of the pipette. The bayonet design ensures that the pipette is not easily dropped, while the soft rubber at the bayonet reduces surface wear on the pipette.

[0028] 2. The provided deformable multi-functional pipette holder is stable and reliable in turntable form, occupies little space, and can be easily sterilized together with the pipette under high temperature and high pressure, reducing the risk of pipette contamination.

[0029] 3. The provided deformable pipette holder can be quickly converted between straight and rotary types, which increases the applicability of the pipette holder and reduces the need for repeated purchases, thus saving costs. Attached Figure Description
