[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 3 and Figure 4 As shown, the present invention provides a pipette tip storage box, which mainly protects the tip through a box body 1 and a box cover 2, and the box cover 2 does not need to be opened when taking out the tip.

[0028] The pipette tip storage box comprises a box body 1 and a box cover 2 arranged on the top of the box body 1, support plates 3 are fixedly connected to both sides of the inner wall of the box body 1, and the two support plates 3 are symmetrically arranged, and a main channel 4 is formed between the two support plates 3;

[0029] A through slot 5 is provided on one side of the box body 1, and the through slot 5 is arranged in the extending direction of the main channel 4. The height of the side of the support plate 3 close to the through slot 5 is lower than the height of the side away from the through slot 5, so that the gun head placed in the main channel 4 slides toward the through slot 5 under the action of gravity, and a support block 6 is fixedly connected to the side of the support plate 3 close to the through slot 5, and the support block 6 is arranged in the through slot 5, and the distance between the two support blocks 6 is equal to the width of the main channel 4;

[0030] A placement block 7 is fixedly connected to one side of the box body 1 where the through slot 5 is provided. A clamping slot 8 is provided on the top of the placement block 7 , and the clamping slot 8 is communicated with the through slot 5 .

[0031] The width of the main channel 4 and the width of the card slot 8 are both larger than the diameter of the middle extension tube 02 , but smaller than the diameter of the pipette connecting tube 01 .

[0032] The current storage box can hold multiple gun tips at one time and is sealed only by the cover 05. Each time the cover 05 is opened, all the gun tips are exposed, and external dust can easily enter the interior of the gun tips, and the gun tips are easily contaminated before use. Therefore, it is necessary to develop a storage box that does not require the cover 05 to be opened to expose all the gun tips when in use.

[0033] In this embodiment, the box body 1 and the box cover 2 are provided to seal the unused gun tips so that they are not easily contaminated. The gun tips are placed inside the main channel 4 which is inclined downward. When taking them, only one gun tip slides into the card slot 8 to be taken out for use at a time. There is no need to open the box cover 2 to expose multiple gun tips at the same time, thereby improving the protection effect of the gun tips.

[0034] In actual use, 1. Open the box cover 2. Put the gun head Figure 1 As shown, they are placed in the main channel 4 in sequence, with the pipette connecting tube 01 at the top of the main channel 4 and the rest of the pipette tip inside the main channel 4;

[0035] 2. Since the main channel 4 is tilted downward, the gun heads slide down one by one, so that the first gun head slides into the slot 8;

[0036] 3. After placing a plurality of gun tips in the main channel 4 in sequence, close the box cover 2, and the pipette gun takes the gun tip from the card slot 8;

[0037] 4. After the gun tips in the card slot 8 are taken out, due to the gravity of the gun tips, the gun tips in the main channel 4 slide down one by one, pass through the through groove 5 and slide into the card slot 8, so that they can be taken out one by one by the pipette gun, so that the gun tips can be taken out one by one without opening the box cover 2, and when taking out the gun tips, there is no need to expose all the gun tips in the box body 1.

[0038] As a preferred embodiment of this embodiment, in order to place more gun heads inside the box 1 and make better use of the space, further, as Figure 4 As shown, the height of the side of the support plate 3 close to the main channel 4 is lower than the height of the side away from the main channel 4, and a plurality of branch channels 9 are opened on the two support plates 3, and the branch channels 9 are all connected to the main channel 4;

[0039] The branch channels 9 on the two support plates 3 are staggeredly distributed on both sides of the main channel 4, so that the branch channels 9 on the two support plates 3 are not on the same straight line.

[0040] The width of the branch channel 9 is larger than the diameter of the middle extension tube 02 , but smaller than the diameter of the pipette connecting tube 01 .

[0041] By providing the branch channel 9 inclined downward, when placing the gun heads, the gun heads are placed in the branch channel 9 in sequence, so that more gun heads can be accommodated in the box body 1.

[0042] In actual use, the gun tips in the branch channel 9 slide into the main channel 4 in sequence, and the gun tips inside the main channel 4 slide into the card slot 8 in sequence. The gun tips in the branch channel 9 away from the through slot 5 slide into the main channel 4 in sequence first.

[0043] In order to further improve the sealing performance of the box body 1, Figure 5 As shown, a sealing cover 10 is slidably connected to the top of the placement block 7, and a limiting groove 11 is provided on the top of the card slot 8, and the width of the limiting groove 11 is greater than the diameter of the pipette connecting tube 01. The sealing cover 10 seals the through groove 5 and protects the gun head inside the card slot 8.

[0044] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
