Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, specifically to an anti-tipping pipette tip box. Background Technology

[0002] In routine laboratory operations, pipette tip holders are commonly used consumable storage containers. Traditional pipette tip holders are typically rectangular in shape, making them prone to tipping over due to impacts or uneven work surfaces, leading to tip spillage and contamination, which affects the accuracy of experimental results. Some tip holders address stability issues by using counterweights or increasing the weight of the holder, but this sacrifices portability. Therefore, developing a stable yet portable tip-proof pipette tip holder is of significant practical importance. Utility Model Content

[0003] The present invention aims to provide an anti-tipping pipette tip box, which significantly improves stability by optimizing the structural design and adding suction cup adsorption function, while maintaining portability, thus providing convenience for experimental operations.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An anti-tipping pipette tip box includes a box body, a tip plate embedded in the box body, and tip holes arranged in an array on the tip plate; a suction cup is fitted on the lower surface of the box body, and pressing the box body can cause the suction cup to adhere to the table surface; the side length of the upper surface of the box body is smaller than the corresponding side length of the lower surface of the box body.

[0006] Preferably, the top of the box is provided with a lid, which is flip-top connected to the box. When closed, the lid and the box together form a cavity for storing the gun head.

[0007] Preferably, a first retaining plate is provided on the outer wall of the flip-up side of the box lid, and a third protrusion is provided on the side of the first retaining plate facing the inside of the box lid. A slot is provided on the top of the outer wall of the box body, and a second protrusion is provided on the inner wall of the slot. After the box lid is closed, the first retaining plate is embedded in the slot and the third and second protrusions are misaligned and engaged.

[0008] Preferably, five suction cups are provided, and the five suction cups are distributed at the four corners and the center of the lower surface of the box.

[0009] Preferably, a stud is vertically fixed to the top of the suction cup, a threaded hole that engages with the stud is provided on the lower surface of the box, and a protruding plate is radially fixed to the side wall of the stud facing the suction cup.

[0010] Preferably, a groove is provided on the top inner side of the box, and a second retaining plate is movably embedded in the groove. A shaft is provided on both side walls of the second retaining plate, and the shaft is rotatably embedded in the inner wall of the groove. A support plate that is horizontally bent towards the inside of the box is provided at the bottom end of the second retaining plate. A rubber pad is provided on the upper surface of the support plate. A first protrusion is provided at the bottom of the side of the second retaining plate facing the inside of the box. The gun head plate can be inserted between the rubber pad and the first protrusion.

[0011] Preferably, the bottom end of the second card plate and the connection point of the tray plate are curved in an arc shape towards the inside of the groove, and the second card plate is in a vertical state when the curved part abuts against the inner side wall of the groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model uses a lid that, when closed, forms a cavity with the box body to store the gun head on the gun head plate. The flip-top lid, along with the engagement of the first locking plate and the slot, and the staggered engagement of the second and third protrusions, facilitates the opening and closing of the lid.

[0014] This invention utilizes a suction cup at the bottom of the box. When the box is pressed, the gas inside the suction cup is expelled, creating a vacuum that allows the box to adhere to the work surface. This physical adhesion replaces traditional weight-adding methods, reducing the risk of the box tipping over. The box's upper surface has a smaller side length than the corresponding lower surface, resulting in an overall expanding shape from top to bottom (narrower at the top and wider at the bottom). This increases the contact area with the work surface, and combined with the vacuum adhesion from the suction cup, significantly improves the stability of the gun tip box during use, reducing the risk of tip spillage and contamination due to the box tipping over.

[0015] This invention utilizes a second locking plate. The two ends of the pipette tip plate abut against the rubber pads on the support plate and are pressed downwards, causing the second locking plate to rotate. After the curved part connecting the support plate and the second locking plate abuts against the inner wall of the groove, the second locking plate can be in a vertical position. Simultaneously, the pipette tip plate can be pressed and embedded between the first protrusion and the rubber pad, achieving a locking and fixing of the pipette tip plate. This prevents the pipette tip plate from shaking or lifting with the pipette tip due to friction between the pipette tip and the pipette tip plate when handling the pipette tip. When the second locking plate is pushed outwards towards the box, the corresponding side of the pipette tip plate can be pushed upwards out of the box, facilitating quick assembly and disassembly of the pipette tip plate. The overall structure is simple, highly stable, and provides convenience for experimental operations.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0027] Example

[0028] Please see Figures 1 to 8 The present invention preferably provides the following technical solution: a tip box for preventing tipping of liquid transfer nozzles, comprising a box body 1, a nozzle plate 3 embedded in the box body 1, and nozzle holes 8 arranged in an array on the nozzle plate 3; a box cover 2 is provided on the top of the box body 1, the box cover 2 is flip-top connected to the box body 1, and the box cover 2 and the box body 1 together form a cavity for storing nozzles after the box body 1 is closed.

[0029] In a further embodiment, a suction cup 6 is fitted on the lower surface of the box body 1. Pressing the box body 1 can cause the suction cup 6 to adhere to the table surface. Five suction cups 6 are provided, and the five suction cups 6 are distributed at the four corners and the center of the lower surface of the box body 1, which can stably adhere the box body 1 to the table surface. Physical adsorption replaces the traditional weight-adding solution, reducing the risk of the box body 1 tipping over.

[0030] In this embodiment, a stud 14 is vertically fixed to the top of the suction cup 6, and a threaded hole 7 that is threaded to the stud 14 is opened on the lower surface of the box body 1. A protruding plate 15 is radially fixed on the side wall of the stud 14 facing the suction cup 6, which is conducive to the disassembly, cleaning, disinfection and assembly of the suction cup 6.

[0031] Furthermore, the side length of the upper surface of the box 1 is smaller than the corresponding side length of the lower surface of the box 1. This structural design makes the box 1 have an expanding shape from top to bottom, narrower at the top and wider at the bottom, which increases the contact area with the table surface. Combined with the vacuum adsorption of the suction cup 6, it greatly improves the stability of the gun head box during use and reduces the risk of the gun head scattering and contaminating due to the box 1 tipping over.

[0032] In a further embodiment, a first latching plate 4 is provided on the outer wall of the flip-up side of the lid 2. A third protrusion 18 is provided on the side of the first latching plate 4 facing the inside of the lid 2. A slot 16 is provided on the top of the outer wall of the box body 1. A second protrusion 17 is provided on the inner wall of the slot 16. After the lid 2 is closed, the first latching plate 4 is embedded in the slot 16 and the third protrusion 18 and the second protrusion 17 are misaligned and engaged. The flip-top lid 2, together with the engagement of the first latching plate 4 and the slot 16 and the misalignment and engagement of the second protrusion 17 and the third protrusion 18, facilitates the opening and closing of the lid 2.

[0033] In a further embodiment, a groove 9 is provided on the top inner side of the box body 1, and a second retaining plate 5 is movably embedded in the groove 9. Shafts 10 are provided on both side walls of the second retaining plate 5, and the shafts 10 are rotatably embedded in the inner wall of the groove 9. A support plate 11, horizontally bent towards the inside of the box body 1, is provided at the bottom end of the second retaining plate 5. A rubber pad 13 is provided on the upper surface of the support plate 11. A first protrusion 12 is provided on the bottom of the side of the second retaining plate 5 facing the inside of the box body 1. The gun head plate 3 can be inserted between the rubber pad 13 and the first protrusion 12. The connection between the bottom end of the second retaining plate 5 and the support plate 11 is curved in an arc shape towards the inside of the groove 9, and when this curved part abuts against the inner wall of the groove 9, the second retaining plate 5... In the vertical position, this structural design allows the second locking plate 5 to rotate after the two ends of the pipette tip plate 3 abut against the rubber pads 13 on the support plate 11 and are pressed downwards. The curved part connecting the support plate 11 and the second locking plate 5 abuts against the inner wall of the groove 9. The second locking plate 5 rotates to the vertical position, allowing the pipette tip plate 3 to be squeezed and embedded between the first protrusion 12 and the rubber pad 13, thereby locking and fixing the pipette tip plate 3. This avoids the phenomenon that the pipette tip plate 3 shakes or is lifted with the pipette tip due to the friction between the pipette tip and the pipette tip plate 3 when picking up the pipette tip. When the second locking plate 5 is pushed outwards towards the outside of the box 1 to rotate, the corresponding side of the pipette tip plate 3 can be pushed upwards out of the box 1, facilitating the quick assembly and disassembly of the pipette tip plate 3.

[0034] In use, the pipette tip plate 3 has several tip holes 8 for inserting pipette tips. When closed, the lid 2, together with the box body 1, forms a receiving cavity for storing the pipette tips on the lid 3. The flip-top lid 2, along with the engagement of the first locking plate 4 and the locking groove 16, and the staggered engagement of the second protrusion 17 and the third protrusion 18, facilitates the opening and closing of the lid 2. Furthermore, the suction cup 6 at the bottom of the box body 1, when pressed, releases gas to create a vacuum that adheres to the work surface. The structural design of the upper surface of the box body 1 having a smaller side length than the corresponding side length of the lower surface, and the overall shape of the box body 1 expanding from top to bottom (narrower at the top and wider at the bottom), increases the contact area with the work surface. Combined with the vacuum adhesion of the suction cup 6, this significantly improves the stability of the pipette tip box during use and reduces the risk of tip spillage and contamination caused by the box body 1 tipping over. Furthermore, the two ends of the pipette tip plate 3 are pressed against the rubber pads 13 on the support plate 11 and pressed downwards, causing the second locking plate 5 to rotate. After the curved part connecting the support plate 11 and the second locking plate 5 abuts against the inner wall of the groove 9, the second locking plate 5 is in a vertical state. At this time, the pipette tip plate 3 is pressed and embedded between the first protrusion 12 and the rubber pad 13, which can realize the locking and fixing of the pipette tip plate 3. This can prevent the pipette tip plate 3 from shaking or being lifted with the pipette tip due to the friction between the pipette tip and the pipette tip plate 3 when picking up the pipette tip. When the second locking plate 5 is pushed to rotate towards the outside of the box 1, the corresponding side of the pipette tip plate 3 can be pushed upwards out of the box 1, which facilitates the quick assembly and disassembly of the pipette tip plate 3.
