Description

Technical Field

[0001] The utility model relates to the technical field of liquid transfer guns, in particular to a magnetic universal liquid transfer gun rack. Background Art

[0002] Pipette is a key tool that is widely used in laboratories and can accurately measure low-dose solvents or samples. However, the current situation in the market regarding the storage of pipettes is not ideal. There are currently few models of pipette racks on the market, and the design is relatively simple, which does not fully consider the actual needs and user experience of the laboratory.

[0003] Specifically, the existing pipette holders have the following major defects:

[0004] 1. The base of the existing pipette holder is large, which will occupy a large area of ​​the fume hood or desktop, making the already limited experimental space even more scarce. In addition, the base of the pipette holder not only occupies valuable experimental space, but also may affect the air circulation in the fume hood, thereby having a potential negative impact on the experimental results.

[0005] 2. Existing pipette holders are easily knocked over during experimental operations and table cleaning. Due to design deficiencies, existing pipette holders often do not fully consider stability design. Once they are hit by external forces, they are easy to tip over, causing the pipette and the tip to fall, and may even cause contamination or damage to the experimental samples.

[0006] 3. Existing pipette racks are usually unable to store the matching pipettes and pipette tips together. In experiments, pipettes and pipette tips are often used together, but existing pipette storage methods often ignore this point. This causes the experimenter to find an additional storage location for the pipette tip when taking it, which not only increases the complexity of the operation, but may also affect the efficiency of the experiment. Summary of the invention

[0007] In view of the problems in the prior art that the pipette holder occupies a large area, is easy to tip over, and cannot accommodate the pipette and the gun head at the same time, the purpose of the utility model is to provide a magnetic universal pipette holder to at least partially solve the above problems.

[0008] To achieve the above purpose, the technical solution of the utility model is:

[0009] A magnetic universal pipette gun rack comprises two magnetic rods located at a distal end and arranged at intervals from each other, two support rods located at a proximal end and arranged at intervals from each other, a bottom plate whose four corners are respectively fixedly connected to the two magnetic rods and the two support rods, and a hanging plate connected between the two support rods; wherein a circle of enclosure is provided on the top surface of the bottom plate.

[0010] In some preferred embodiments, the hanging plates are arranged in an inclined manner.

[0011] In some preferred embodiments, the two support rods are parallel to each other and parallel to the hanging plate.

[0012] In some preferred embodiments, the hanging plate is detachably fixedly connected to the support rod.

[0013] In some preferred embodiments, the magnetic rod and the support rod are both detachably fixedly connected to the base plate.

[0014] In some preferred embodiments, a projection of a distal side wall of the magnetic rod on a horizontal plane protrudes beyond a distal edge of the bottom plate.

[0015] In some preferred embodiments, the magnetic rod is perpendicular to the bottom plate.

[0016] In some preferred embodiments, the distal side walls of the magnetic rods are each provided with an adsorption surface suitable for magnetic adsorption, and the adsorption surfaces on the two magnetic rods are located in the same plane.

[0017] In some preferred embodiments, a connecting rod is further included, and the connecting rod is fixed between the magnetic attraction rod and the adjacent support rod.

[0018] In some preferred embodiments, the connecting rod and the supporting rod, and the connecting rod and the magnetic rod can be detachably and fixedly connected.

[0019] By adopting the above technical solution, the beneficial effect of the utility model is that the magnetic universal pipette gun holder provided by the embodiment of the utility model does not need to be placed on the desktop, so it will not occupy valuable experimental space, and it only needs to be magnetically adsorbed on the wall of the fume hood, and it will not affect the air circulation in the fume hood, so it will not have a potential negative impact on the experimental results. In addition, because the pipette gun holder is magnetically adsorbed on the wall of the fume hood, it will not be accidentally knocked over, so that the pipette gun and the gun tip will not fall, and will not cause contamination or damage to the experimental sample. The utility model can store the matching pipette gun and the gun tip together, so that the experimenter does not need to find an additional storage location for the gun tip when taking the gun tip, so that the complexity of the operation will not be increased, and the efficiency of the experiment will not be affected.

[0027] Example

[0028] A magnetic universal pipette holder, such as Figure 1 and Figure 2 As shown, it includes a magnetic rod 1, a support rod 2, a base plate 3, a hanging plate 4 and a fence 5.

[0029] The magnetic rod 1 is configured as a rod-shaped structure made of magnetic material, such as a permanent magnetic rod, or a plastic rod or a metal rod with a permanent magnet embedded in a local position. This configuration allows the magnetic rod 1 to be adsorbed on the iron fume hood wall. Two magnetic rods 1 are configured, and the two magnetic rods 1 are arranged at a distance from each other on the far end side of the magnetic universal pipette holder, and the far end refers to the side of the magnetic universal pipette holder away from the user.

[0030] The support rod 2 is configured as a rod-shaped structure made of plastic or metal material. There are two support rods 2, and the two support rods 2 are arranged at a distance from each other on the proximal side of the magnetic universal pipette holder, where the proximal side refers to the side of the magnetic universal pipette holder close to the user. The other two magnetic rods 1 and the two support rods 2 are located at approximately the same height, thereby forming a three-dimensional space together.

[0031] The bottom plate 3 is configured as a rectangular plate, and its four corners are fixedly connected to the two magnetic rods 1 and the two support rods 2 respectively. For example, the bottoms of the two magnetic rods 1 are detachably fixedly connected to the two distal corners of the top surface of the bottom plate 3 by screws, and the bottoms of the two support rods 2 are detachably fixedly connected to the two proximal corners of the top surface of the bottom plate 3 by screws.

[0032] When connected, the projection of the distal side wall of the magnetic rod 1 on the horizontal plane protrudes beyond the distal edge of the bottom plate 3. This arrangement allows the distal side wall of the magnetic rod 1 to be unobstructed by the bottom plate 3, thereby being adsorbed on the wall of the fume hood. In addition, the distal side walls of the magnetic rod 1 are further configured to be provided with an adsorption surface (in a planar shape) suitable for magnetic adsorption, and the adsorption surfaces on the two magnetic rods 1 are located in the same plane. For example, the magnetic rods 1 are configured to be square rod-shaped structures. This arrangement allows the two magnetic rods 1 to be more firmly adsorbed on the wall of the fume hood. Of course, if the magnetic rod 1 is adsorbed by a permanent magnet embedded in a local position thereof, the permanent magnet needs to be embedded in the adsorption surface in a flush manner.

[0033] The two ends of the hanging plate 4 are respectively connected to the upper parts of the two support rods 2, such as mortise and tenon connections or screw connections, so that it can be easily disassembled. Usually, the hanging plate 4 is in the shape of a long strip, and its length direction is consistent with the horizontal direction, and the length direction of the hanging plate 4 is also parallel to the plane defined by the two magnetic rods 1 (it can also be said to be the wall surface of the fume hood wall). In addition, the board surface of the hanging plate 4 is inclined, and its reference state is that the two magnetic rods 1 are vertically adsorbed on the wall of the fume hood, and the board surface of the hanging plate 4 is inclined toward the proximal end along the top-down direction, so that the pipette gun hung on the hanging plate 4 is more inclined toward the user side, and vice versa, the intrusion distance of the pipette gun toward the side of the fume hood wall is reduced, so that the volume of the pipette gun holder in this embodiment can be reduced.

[0034] More preferably, the two support rods 2 are also arranged in an inclined shape, and the inclination direction and angle are the same as those of the hanging plate 4, that is, the two support rods 2 are parallel to each other and parallel to the hanging plate 4. In this way, the size of the pipette holder in this embodiment gradually decreases from bottom to top, thereby further reducing the volume of the pipette holder.

[0035] The enclosure 5 is also rectangular and fixed on the top surface of the bottom plate 3, and the magnetic rod 1 and the support rod 2 are arranged outside the enclosure range of the enclosure 5. In order to facilitate disassembly, a circle of slots matching the enclosure 5 is formed on the top surface of the bottom plate 3, and the enclosure 5 can be inserted into the slots. Of course, in other preferred embodiments, the enclosure 5 can also be integrally formed or welded with the bottom plate 3.

[0036] It is easy to understand that the open space formed by the bottom plate 3 and the enclosure 5 can be used to store pipette tips. In order to prevent the pipette tips from falling, the present embodiment further configures the bottom plate 3 to be perpendicular to the magnetic rod 1. In this way, when the magnetic rod 1 is vertically adsorbed on the wall of the fume hood, the bottom plate 3 is arranged horizontally, so that the pipette tips will not roll, gather and fall due to the tilt of the bottom plate 3.

[0037] It can be seen from the above structure that the magnetic rod 1 is only connected to the bottom plate 3. Therefore, in order to enhance the stability of the pipette gun holder, a connecting rod 6 is further fixed between each magnetic rod 1 and an adjacent support rod 2, that is, two connecting rods 6 are arranged on both sides of the length direction of the hanging plate 4, which will not affect the use of the hanging plate 4. In order to facilitate disassembly, the connecting rod 6 and the support rod 2, and the connecting rod 6 and the magnetic rod 1 are also configured to be detachably fixedly connected. For example, a plug hole adapted to the connecting rod 6 is opened on the magnetic rod 1 and the support rod 2, and then a pin hole connected to the plug hole is opened on the magnetic rod 1 and the support rod 2, and a pin hole is also opened on the connecting rod 6 accordingly, so that the connecting rod 6 is fixed to the magnetic rod 1 and the support rod 2 by a pin, and a pull ring, a pull rope or a protrusion suitable for pulling is set on the outside of the pin, so as to facilitate the removal of the pin for easy disassembly; or in other preferred embodiments, the connecting rod 6 and the support rod 2, and the connecting rod 6 and the magnetic rod 1 can also be configured to be fixed by screws.

[0038] The use process of the magnetic universal pipette gun holder provided by the embodiment of the utility model is as follows:

[0039] Before use, the pipette rack that is stored in scattered parts is assembled first, the enclosure 5 is fixed on the bottom plate 3, the hanging plate 4 is fixed between the two support rods 2, the two magnetic rods 1 and the two support rods 2 are fixed by the connecting rod 6, and finally the two connected magnetic rods 1 and the two support rods 2 are fixed on the bottom plate 3. When in use, the magnetic rod 1 is adsorbed on the wall of the fume hood and fixed. At this time, the hanging plate 4 is inclined to facilitate hanging a number of pipettes, and the bottom plate 3 is horizontal to facilitate storing a number of pipette tips.

[0040] Compared to the traditional pipette gun holder, the magnetic universal pipette gun holder provided by the embodiment of the utility model does not need to be placed on the desktop, so it will not take up valuable experimental space, and it only needs to be magnetically attached to the wall of the fume hood, and will not affect the air circulation in the fume hood, so it will not have a potential negative impact on the experimental results. In addition, because the pipette gun holder is magnetically attached to the wall of the fume hood, it will not be accidentally knocked over, so that the pipette gun and the gun tip will not fall, and will not cause contamination or damage to the experimental sample. The utility model can store the matching pipette gun and the gun tip together, so that the experimenter does not need to find an additional storage location for the gun tip when taking the gun tip, so that the complexity of the operation will not be increased, and the efficiency of the experiment will not be affected.

For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
