Description

Liquid transfer device support

Technical Field

The utility model relates to an experimental apparatus, in particular to a pipette bracket.

Background

A pipette, also called a pipette gun, is an instrument for quantitatively transferring liquid. In the case of analytical testing, a pipette is generally used to remove small or minute amounts of liquid. The pipettes can be classified into gas piston pipettes and external piston pipettes according to the principle. A pipette, also called a pipette, is a metering tool that removes liquid from an original container into another container over a range of ranges. Is widely used in the fields of biology, chemistry and the like.

In laboratory experiments, the operation is generally carried out on an aseptic operation table, the area of a table top is limited, the occupied area of the existing pipetting gun rack is large, and most of areas such as long rows and circles are likely to have a large amount of redundancy, so that the utilization rate of the table top is greatly reduced.

Chinese patent (CN 211677843U) provides a pipette, which comprises a support frame and a tightening device, and clamps the pipette on the support frame, but in practical use, the following problems are also involved: the volume is overlarge in use, the area of a table surface occupied by one liquid dispenser is completely the same as that of a plurality of liquid dispensers, and the area of a test table is excessively occupied.

In order to solve the above problems, the applicant proposes a pipette holder.

Disclosure of Invention

The utility model aims to provide a pipette support, which solves the problem that no matter how many pipettes are used in the prior art, the whole space of the pipette support is occupied.

In order to achieve the above purpose, the present utility model provides the following technical solutions:

the utility model provides a pipettor support, includes the base and sets up in the support frame of base upper surface, the support frame include pillar and a plurality of bracing piece, a plurality of the bracing piece rotates and cup joints on the pillar, the bracing piece is kept away from the pillar end and is provided with places the ring, bracing piece upper surface and lower surface are provided with arc spacing groove and stopper respectively.

Optionally, a damping ring is further arranged on the contact surface of the support rod and the support post.

Optionally, the base is further provided with a balancing weight groove.

The beneficial effects are that: 1. through the balancing weight groove that sets up the base, solved in use pipettor and placed too much and toppled over easily, placed too little problem that the not good transport of base bearing.

2. Through setting up the support frame, realized not needing to occupy a large amount of upper spaces when using a small amount of pipettors, only need the problem of a small amount of upper spaces, solved the support and taken up too big space problem among the prior art.

Detailed Description

The following description of the preferred embodiments of the present utility model refers to the accompanying drawings, which make the technical contents thereof more clear and easier to understand. This utility model may be embodied in many different forms of embodiments and should not be construed as limited to the embodiments set forth herein.

In the drawings, like structural elements are referred to by like reference numerals and components having similar structure or function are referred to by like reference numerals. The dimensions and thickness of each component shown in the drawings are arbitrarily shown, and the present utility model is not limited to the dimensions and thickness of each component. The thickness of the components is exaggerated in some places in the drawings for clarity of illustration.

Example 1

The utility model provides a pipettor support, includes base 1 and sets up in the support frame 2 of base 1 upper surface, and support frame 2 includes pillar 21 and a plurality of bracing piece 22, and a plurality of bracing pieces 22 rotate and cup joint on pillar 21, and the bracing piece 22 is kept away from pillar 21 end and is provided with places the ring 221, and bracing piece 22 upper surface and lower surface are provided with arc spacing groove 223 and stopper 224 respectively.

In the utility model, a rotatable supporting frame 2 is adopted, each supporting rod 22 can rotate independently, in use, a plurality of supporting rods 22 are needed to rotate out, and 7 supporting rods 22 are preferably arranged in the embodiment.

According to the utility model, the arc-shaped limit grooves 223 and the limit blocks 224 arranged on the support rods 22 are mutually matched, and the limit blocks 224 freely slide in the limit grooves 223, so that the placing rings 221 of each support rod 22 cannot interfere with each other after being unfolded, and the using area of the support is reduced.

In the utility model, the damping ring 222 is arranged between the support rod 22 and the support column 21, and the damping ring 222 does not drive other support rods 22 to rotate due to small rotation when the support rod 22 is pulled out, so that the process of finishing is reduced in use, and the unfolded shape of the support frame 2 is not influenced due to a small action in use.

In the embodiment, the base 1 is preferably provided in a sector shape with an angle of 90 degrees, and the shape of the base is beneficial to being used singly and placed at the corner of the operating platform; the combined type pipette can also be used in combination, and the combined type pipette can be transversely formed into a strip shape or a round shape, so that the combined type pipette can adapt to the change of the number of pipettes in use, and in actual operation, the number of pipettes is different from two to tens of pipettes, and the combined type pipette can be effectively used with an actual use field Jing Tiege.

In the utility model, the upper surface of the base 1 is also provided with the balancing weight groove 11, in actual use, if the base 1 is not heavy enough, the base can be easily toppled over after a plurality of pipettes are hung, but if the base 1 is too heavy, the base 1 is not easy to move, and in biological and chemical laboratories, sterile environment needs to be ensured, and the cleaning of a test bed can be influenced by the too heavy base 1.

The balancing weight groove 11 can be added with balancing weights under the condition of using more liquid movers, the gun heads of the liquid movers placed at the lowest layer can not be influenced to touch the balancing weights, meanwhile, the cleaning links after the test are difficult to move, the balancing weights are only required to be lifted one by one, and the whole liquid movers are movable at the sides of the support frame.

Working principle: in use, according to the requirements of the use scene, a corresponding number of brackets are selected, and a small number of pipettes select one bracket, so that the brackets can be prevented from being attached to the corners of the sterile operation table, the placement space is reduced; after the usage amount is increased, a plurality of brackets can be combined for use; if the number of the pipettes is too large in use, the balancing weights can be placed in the balancing weight grooves 11, so that the gravity center can be stabilized and the bracket cannot fall down; the used and to-be-used pipettes are hung on the placing ring 221 when in use.
