[0023] Reference Figure 1-2 The figure shows a preferred embodiment of the present invention.

[0024] The tip box provided in this embodiment, which is convenient for taking out the pipette tips 14 , can be used to take out the pipette tips 14 .

[0025] The tip box for facilitating the removal of the pipette tip comprises a box body 11 and a cover plate 12. The box body 11 is provided with a plurality of insertion cavities 13, the plurality of insertion cavities 13 are arranged vertically, an insertion port is formed on the box body 11, the insertion port is connected to the insertion cavity 13, and an elastic structure is provided at the bottom of the insertion cavity 13; one side of the cover plate 12 is hinged to one side of the box body 11 to form a hinged side, the cover plate 12 is formed with a plurality of device removal ports corresponding to the insertion port, and the cover plate comprises a movable pressure cover 26 connected to the edge of the device removal port,

[0026] When the pipette tip 14 is inserted into the insertion cavity 13, the bottom of the pipette tip 14 presses against the elastic structure. When the cover plate 12 is sealed on the box body 11, the device removal port is opposite to the insertion port and is connected with the insertion port, and the movable pressure cover 26 is pressed down, the pipette tip 14 is driven by the elastic structure to bounce upward and push open the movable pressure cover 26.

[0027] By providing a box body 11 and a cover plate 12, a plurality of insertion cavities 13 for storing pipette tips 14 are formed on the box body 11, and the cover plate 12 is hinged to one side of the box body 11 to form a hinged side. When the cover plate 12 covers the box body 11, the device removal port formed on the cover plate 12 is connected with the insertion port formed on the box body 11, and the insertion port is connected with the insertion cavity 13, and an elastic structure is placed at the bottom of the insertion cavity 13. When the movable pressure cover 26 connected to the device removal port is pressed and moved downward, the pipette tip 14 moves downward, so that the elastic structure is compressed, and the elastic structure applies an upward restoring force to the pipette tip 14, so that the pipette tip 14 bounces upward, which is convenient for removal from the box body 11.

[0028] Specifically, the plurality of insertion cavities 13 are arranged in an array, which makes it very convenient to insert the pipette tip.

[0029] The cover plate 12 extends downward to form a plurality of clamping rings 16 surrounding the device taking port, and the lower end of the clamping ring 16 is connected with elastic glue, which can compress the upper surface of the box body 11 to prevent the cover plate 12 from moving when the pipette tip 14 protrudes upward.

[0030] The diameter of the removal port is larger than the outer diameter of the pipette tip 14, and the removal port is consistent with the inner diameter of the insertion port. A soft rubber ring 27 protrudes from the inner circumferential surface of the removal port. The diameter of the soft rubber ring 27 is 0.5mm-1mm larger than the outer diameter of the pipette tip 14. In this way, the soft rubber ring 27 can temporarily fix the pipette tip 14 after it pops up and will not fall back.

[0031] In addition, an adhesive layer 17 is provided on the edge of the movable pressure cover 26, and the adhesive layer 17 is arranged closely to the cover plate 12. When the pipette tip 14 is taken out, the movable pressure cover 26 can still seal the device removal port.

[0032] The elastic structure includes a protrusion 18, a return spring 19 and a fixed block 24. The fixed block 24 is fixedly connected to the bottom of the insertion cavity 13. The inner circumference of the return spring 19 surrounds the fixed block 24, and the lower end of the return spring 19 is fixedly connected to the fixed block 24. The protrusion 18 is connected to the upper end of the return spring 19, and the lower end of the pipette tip 14 contacts the upper end of the protrusion 18.

[0033] An embedding hole is formed on the lower surface of the protrusion 18, and the upper end of the return spring 19 is embedded in the embedding hole and fixedly connected to the inner circumference of the embedding hole.

[0034] A first convex ring is formed on the side of the protrusion 18, and a second convex ring is provided on the inner wall of the insertion cavity 13. The first convex ring and the second convex ring abut against each other, and the reset spring 19 is in a compressed state. When the movable pressure cover 26 is pressed down, the first convex ring and the second convex ring are disengaged, and the reset spring 19 drives the protrusion to move upward, pushing the pipette tip 14 upward.

[0035] A locking block 21 is connected to the edge of the box body 11 parallel to the hinged side, and a fastening ring 22 is connected to the edge of the cover plate 12 parallel to the hinged side. The fastening ring 22 is movably fastened to the locking block 21, so as to fasten the cover plate 12 to the box body 11.

[0036] In addition, a shielding edge 23 is extended outward from the edge of the cover plate 12 except the hinged side edge, and a fastening ring 22 is formed on the shielding edge 23 .

[0037] Yet another embodiment,

[0038] An outer convex layer is formed on the inner wall of the insertion cavity 13, and a protrusion 18 is provided in the insertion cavity 13. A return spring 19 is surrounded on the upper surface of the protrusion 18, wherein the lower end of the return spring 19 is connected to the protrusion 18, and the upper end of the return spring 19 is connected to the outer convex layer. When the movable pressure cover 26 is pressed down and pressed onto the pipette tip 14, the pipette tip 14 is driven to press the protrusion 18 downward, thereby pulling the return spring 19 to be tensioned, and the return spring 19 drives the protrusion 18 to reset, thereby driving the pipette tip 14 to pop up.

[0039] The outer side of the projection 18 is formed with a concave-convex ring connected with the return spring 19; the distance between the projection 18 and the bottom of the insertion cavity 13 is less than the thickness of the projection 18, so as to prevent the projection 18 from descending too long.

[0040] Yet another embodiment,

[0041] A fixing ring is formed on the upper surface of the protrusion 18 , and the fixing ring covers the lower part of the pipette tip 14 . When the protrusion 18 moves upward and pushes open the movable pressure cover 26 , the pipette tip 14 will not shake and can be taken out directly.

[0042] The inner diameter of the fixing ring is larger than the outer diameter of the pipette tip 14 , and the fixing ring spreads outward from top to bottom, so that the fixing ability of the pipette tip 14 can be enhanced.

[0043] The movable pressure cover 26 is transparent, so that the user can check whether the pipette tip 14 in the current insertion cavity 13 has been taken out.

[0044] There is another embodiment, in which both sides of the movable pressure cover 26 are hinged to the edge of the device taking port, and the middle of the movable pressure cover 26 is cracked. When the middle of the movable pressure cover 26 is pressed down, the protrusion 18 is driven by the reset spring 19 to move upward, driving the pipette tip 14 to move upward, so that the pipette tip 14 is pushed toward the center of the movable pressure cover 26 for easy removal.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
