Description

Technical Field

[0001] The utility model belongs to the technical field of pipettes, and particularly relates to a novel tip box holder. Background Art

[0002] A pipette is a type of liquid transfer device, commonly used in laboratories for the transfer of small or trace amounts of liquid. Pipettes of different specifications are used with different sizes of pipette tips. Of course, the pipette tips of the same pipette can also be matched with different sizes of tips, and several tips are stored in a tip box. Usually, the tip box is placed on the laboratory bench. When in use, the tip box is opened to expose the tips, and then the pipette tip is aligned with and inserted into the tip, and then taken out for liquid aspiration or drainage.

[0003] In the routine operation process of the laboratory, when an operator inserts a pipette tip, the following situations usually occur:

[0004] 1. If the force when inserting the pipette tip into the tip is too large, it will cause the entire tip box to be lifted when it is lifted, resulting in the scattering of tips, causing pollution, reducing efficiency and wasting resources;

[0005] 2. When there are only one or two rows of tips left, or when the operator uses too much force, too quickly or unevenly, there is also a risk of tipping over the tip box. Moreover, it is very easy to cause the pipette tip to break or deform, resulting in its inability to be used normally, not only wasting the pipette tip resources, but also possibly contaminating the experimental samples due to the broken fragments or deformed pipette tips, thus affecting the accuracy of the experimental results.

[0006] Therefore, it is necessary for us to design a novel tip box fixing device to solve these problems. Summary of the Utility Model

[0007] The problem to be solved by the utility model is to provide a novel tip box holder, which can not only avoid the waste and pollution caused by the scattering of tips, but also greatly reduce the damage to the pipette tips, thereby ensuring the experimental progress and experimental results.

[0008] To solve the above technical problems, the technical solution adopted by the utility model is: a novel tip box holder, including a movable support frame, an open receiving cavity provided on the movable support frame for carrying the tip box, and a clamping component provided on the movable support frame and inserted into the receiving cavity. When the tip box is placed in the receiving cavity, its outer wall applies pressure to the clamping component and causes the clamping component to elastically deform, thereby realizing the relative fixation of the tip box and the support frame.

[0009] Further, the clamping component includes a mounting member disposed on the movable support frame, and an elastic clamping member connected to the mounting member and abutting against the outer wall of the tip cartridge. An external force is applied to the elastic clamping member through the tip cartridge to cause it to deform, thereby realizing the clamping of the tip cartridge and the movable support frame.

[0010] Further, the elastic clamping member includes a first connecting piece abutting against the outer wall of the tip cartridge, and an arc-shaped connecting piece disposed at the end of the first connecting piece away from the mounting member. The arc-shaped connecting piece bends outward relative to the tip cartridge.

[0011] Further, the elastic clamping member further includes a second connecting piece connecting the mounting member and the first connecting piece, which is a U-shaped structure with an opening facing the mounting member.

[0012] Further, the accommodating cavity is provided with stepped protrusions connected in sequence and increasing in height gradually. It includes a first step abutting against the outer wall of the tip cartridge, a third step provided with the mounting member, and a second step disposed between the first step and the third step. When the arc-shaped connecting piece receives an external force from the tip cartridge, it can abut against the side wall of the second step and move away from the second step when the external force is withdrawn.

[0013] Further, a card slot recessed in the direction away from the tip cartridge is provided on the side wall of the second step, which is adapted to the end of the arc-shaped connecting piece away from the first connecting piece.

[0014] Further, the side walls of the first step enclose the accommodating cavity, and a first notch recessed outward is provided thereon.

[0015] Further, a second notch communicating with the first notch is provided on the second step.

[0016] Further, a third notch recessed toward the bottom of the tip cartridge is provided on the third step.

[0017] Further, a bottom supporting panel abutting against the bottom of the tip cartridge is provided in the accommodating cavity, and a blind hole recessed in the direction away from the tip cartridge is provided thereon.

[0018] With the above technical solution, a clamping component is provided on the support frame, and the relative fixation of the tip box and the movable support frame is realized by means of its elastic deformation. Even if the force of inserting the gun head into the tip is too large, it will not cause the movement of the entire tip box when lifted. The relatively fixed tip box is more stable, avoiding the possibility of tipping over. This design provides relatively stable operating conditions for the operator. Regardless of the number of tips in the tip box, it will not cause the tip box to tip over, nor will it damage the gun head. In addition, each part of the elastic clamping member is closely attached to other components through elastic deformation, forming a stable connection structure, which is not only firm and reliable, but also can adapt to a certain amount of deformation, preventing loosening or falling off caused by slight differences between components.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present utility model will be further described below in conjunction with the embodiments and the drawings:

[0024] The technical solution adopted by the present utility model is: as Figure 1 and Figure 2As shown in the figure, a new type of tip box holder includes a movable support frame 100, an open receiving cavity 400 provided on the movable support frame 100 for carrying the tip box 200, and a clamping component 300 provided on the movable support frame 100 and inserted into the receiving cavity 400. When the tip box 200 is placed in the receiving cavity 400, its outer wall applies pressure to the clamping component 300 and causes the clamping component 300 to elastically deform, thereby realizing the relative fixation of the tip box 200 and the support frame 100. In this embodiment, the movable support frame 100 includes a support frame body and universal wheels provided at the bottom of the support frame body, and the receiving cavity 400 is provided inside the support frame body. During use, the position of the tip box 200 can be flexibly adjusted according to the experimental position, which is very convenient, time-saving and labor-saving, and avoids contamination caused by direct human contact with the tip box. Specifically, a receiving cavity 400 recessed inward is provided at the top of the support frame body. When the tip box 200 is placed into the receiving cavity 400 from top to bottom, an outward pressure is applied to the clamping component 300 through its outer wall. Under the action of the external force, the clamping component 300 elastically deforms, and based on Newton's third law, an equal and opposite reaction force is generated on the tip box 200, thereby temporarily fixing the tip box 200 in the receiving cavity 400. Even if the force of inserting the tip into the tip is too large, it will not cause the entire tip box 200 to move when lifted. The relatively fixed tip box 200 is more stable, avoiding the possibility of tipping over. This design provides relatively stable working conditions for the operator. Regardless of the number of tips in the tip box, it will not cause the tip box to tip over or damage the tips. It should be noted that the technical solution of this application does not specifically limit the shape and material of the movable support frame 100, as long as it is ensured that the support frame body has an appropriate weight, which can safely carry the tip box and effectively prevent tipping accidents caused by external forces.

[0025] Preferably, as Figure 3 shown in the figure, the clamping component 300 includes a mounting member 310 provided on the movable support frame 100 and an elastic clamping member 320 connected to the mounting member 310 and abutting against the outer wall of the tip box 200. An external force is applied to the elastic clamping member 320 by the tip box 200 to cause it to elastically deform, thereby realizing the clamping of the tip box 200 and the movable support frame 100. The relatively fixed tip box 200 and the support frame 100 can ensure stability during use, avoiding the occurrence of tipping accidents and helping to improve experimental efficiency.

[0026] Preferably, the elastic clamping member 320 includes a first connecting piece 321 abutting against the outer wall of the tip cartridge 200, and an arc-shaped connecting piece 322 provided at the end of the first connecting piece 321 away from the mounting member 310. In this embodiment, the first connecting piece 321 is also an arc-shaped structure, and its radian is smaller than that of the arc-shaped connecting piece 322. The end of the arc-shaped connecting piece 322 away from the first connecting piece 321 faces away from the accommodating cavity 400, so as to Figure 3 Taking the elastic clamping member 320 on the right side in Figure 3 as an example, during the process of the first connecting piece 321 deforming and moving to the right, the end of the arc-shaped connecting piece 322 away from the first connecting piece 321 moves in a direction gradually away from the accommodating cavity 400. Here, the left side of the first connecting piece 321 has a certain contact surface with the outer wall of the tip cartridge 200, which can stably support and temporarily fix the tip cartridge 200 in the accommodating cavity 400. During the connection process, each part of the elastic clamping member 320 is closely attached to other components through elastic deformation to form a stable connection structure. This connection method is not only firm and reliable, but also can adapt to a certain amount of deformation, preventing loosening or falling off caused by slight differences between components.

[0027] Preferably, the elastic clamping member 320 further includes a second connecting piece 323 connecting the mounting member 310 and the first connecting piece 321, which is a U-shaped structure with an opening facing the mounting member 310. In this embodiment, the end of the second connecting piece 323 away from the mounting member 310 is sequentially connected to the first connecting piece 321 and the arc-shaped connecting piece 322. When the first connecting piece 321 is externally squeezed, its elastic deformation can absorb part of the energy, thereby playing a role in buffering and shock absorption.

[0028] Preferably, the accommodating cavity 400 is provided with stepped protrusions 410 that are sequentially connected and gradually increase in height. It includes a first step 411 abutting against the outer wall of the tip cartridge 200, a second step 412 abutting against the arc-shaped connecting piece 322, and a third step 413 provided with the mounting member 310. The arc-shaped connecting piece 322 can abut against the second step 412 and move away from the second step 412 when the external force is withdrawn.

[0029] Preferably, a card slot 4121 recessed in a direction away from the tip cartridge 200 is provided on the side wall of the second step 412, which is adapted to the end of the arc-shaped connecting piece 322 away from the first connecting piece 321. In this embodiment, when the first connecting piece 321 is compressed and deformed outward under the pressure from the tip cartridge 200, at the same time, the arc-shaped connecting piece 322 is inserted into the card slot 4121. The design of the card slot 4121 enables the arc-shaped connecting piece 322 to be firmly inserted into the side wall of the second step 412. This physical connection enhances the stability of the overall structure. When subjected to external forces, the cooperation between the card slot 4121 and the arc-shaped connecting piece 322 can reduce structural deformation and improve the overall impact resistance.

[0030] Preferably, the side walls of the first step 411 enclose a receiving cavity 400, and a first notch 4111 is formed on it and recessed outward. In this embodiment, when the tip cartridge 200 is placed in the receiving cavity 400, it is equivalent to dividing a large cavity into two parts. One part is used as the receiving cavity 400 for placing the tip cartridge 200, and the other part of the cavity is exposed on the outside. On the one hand, it reduces the contact area between the side wall of the first step 411 and the outer wall of the tip cartridge 200, and only a very small force needs to be applied to the tip cartridge 200 to take it out of the receiving cavity 200. On the other hand, an external force can be directly applied to the bottom of the tip cartridge 200 through this part of the cavity (i.e., the first notch 4111), making it easier to separate it from the movable support frame 100. In addition, the notch design can be used as a positioning point or guiding groove during installation to help the user accurately place the tip cartridge 200 in the appropriate position and improve work efficiency.

[0031] Preferably, a second notch 4121 communicating with the first notch 4111 is formed on the second step 412.

[0032] Preferably, a third notch 4131 recessed toward the bottom of the tip cartridge 200 is formed on the third step 413, reducing the obstruction to the tip cartridge 200. On the one hand, it is convenient for the operator to observe the usage situation of the tips in the tip cartridge 200 in a timely manner from multiple angles. On the other hand, it also helps to reduce the weight of the overall structure, making the movement smoother and more stable.

[0033] Preferably, a bottom supporting panel 430 abutting against the bottom of the tip cartridge 200 is provided in the receiving cavity 400, and a blind hole 431 recessed in the direction away from the tip cartridge 200 is formed on it. In this embodiment, the bottom supporting panel 430 is made of metal material, increasing the overall weight and giving the tip cartridge 200 stable support. It can not only safely carry the tip cartridge 200 but also effectively prevent the tipping accident caused by external force.

[0034] In this embodiment, when the tip cartridge 200 is placed in the receiving cavity 400, only part of the side wall of the first step 411 abuts against it, and the exposed first notch 4111 makes it easier for the tip cartridge 200 to be inserted into or pulled out of the receiving cavity 400, thus simplifying the installation and disassembly process. During use, the clamping component 300 and the receiving cavity 400 that match it can be flexibly selected according to the size of the tip cartridge 202. When maintenance or replacement of the clamping component 300 is required, the design of the elastic clamping member 320 makes this process simpler and faster, reducing the maintenance cost and time cost.

[0035] With the above technical solution, a clamping component is provided on the support frame, and the relative fixation of the tip box and the movable support frame is realized by means of its elastic deformation. Even if the force of inserting the gun head into the tip is too large, it will not cause the movement of the entire tip box when lifted. The relatively fixed tip box is more stable, avoiding the possibility of tipping over. This design provides relatively stable working conditions for the operator. Regardless of the number of tips in the tip box, it will not cause the tip box to tip over, nor will it damage the gun head. In addition, each part of the elastic clamping part is closely attached to other parts through elastic deformation, forming a stable connection structure, which is not only firm and reliable, but also can adapt to a certain amount of deformation, preventing loosening or falling off caused by small differences between parts.
