Example

[0031] Refer to the attached Figures 1 to 7 A pipette tip storage box includes a box body 1, a storage cavity 2 is provided in the box body 1, a box cover 3 is provided at the upper end of the box body 1, and a pipette tip outlet 4 is provided at one side of the lower end of the box body 1. Figure 2 As shown, three staggered feeding chutes 5 are arranged in the accommodating chamber 2 from top to bottom, and the pipette tip 9 can automatically slide down from the top feeding chutes 5 to the next feeding chutes 5 in sequence under the action of gravity, until it slides to the bottom of the bottom feeding chutes 5. The problem of messy accumulation of pipette tips 9 in the traditional accommodating method is avoided, and the user does not need to search among a pile of tips, and can quickly obtain the pipette tip 9 in the material taking position.

[0032] A limiting block 8 is provided at the bottom of the lowermost material discharge chute 5, a supporting frame 7 is provided on the outer side of the limiting block 8, and a material picking component 6 is provided below the limiting block 8. The material picking component 6 places a pipette tip 9 at the lower end onto the supporting frame 7 each time.

[0033] The unloading chute 5 includes an inclined chute plate 51 and a limit bar 53 . The limit bar 53 is arranged above the chute plate 51 in parallel. The limit bar 53 is fixed in the accommodating cavity 2 through a connecting block 52 .

[0034] The material picking assembly 6 includes a lifting block 61, a connecting base 62, a supporting seat 63 and a rocker 64. The lifting block 61 is movably arranged on the limit block 8 and is located below a pipette tip 9 at the lowest end. The connecting base 62 is installed at the bottom of the box body 1 by bolts, and the supporting seat 63 is fixed on the connecting base 62. The middle section of the rocker 64 is rotatably installed on the supporting seat 63 by a pivot 65.

[0035] One end of the rocker plate 64 is arranged below the lifting block 61 , and a pressing plate 66 is arranged at the other end. A return spring 67 is fixedly mounted on the lower surface of the rocker plate 64 near one end of the pressing plate 66 , and the return spring 67 is fixed on the connecting base 62 .

[0036] A material unloading slope 81 is provided at the upper end of the limit block 8, guide blocks 613 are provided at both ends of the lifting block 61, guide grooves 82 matching with the guide blocks 613 are provided on both sides of the limit block 8, and a lifting slope 611 and a partition block 612 are provided at the upper end of the lifting block 61. The lifting slope 611 is located below a pipette tip 9 at the lowest end, and the partition block 612 is located below between the two pipette tips 9 at the lowest end.

[0037] Working principle:

[0038] The pipette tip 9 is placed in the top unloading chute 5, and the slide plate 51 of the unloading chute 5 is tilted. Under the action of gravity, the pipette tip 9 begins to slide down along the slide plate 51. The limit bar 53 is fixed in the accommodating chamber 2 through the connecting block 52 and is parallel to the top of the slide plate 51, which limits the pipette tip 9 and prevents it from stacking during the sliding process, which is not conducive to subsequent single use, and ensures that the pipette tip 9 can slide smoothly along the slide plate 51 to the next unloading chute 5 in turn, and thus passes through three staggered unloading chutes 5 in turn until it slides to the bottom of the bottom unloading chute 5.

[0039] When the pipette tip 9 reaches the bottom of the lowermost unloading chute 5, the stopper 8 blocks and positions it. When the pipette tip 9 needs to be taken, the operator presses the pressing plate 66, and the pressing plate 66 drives the seesaw 64 to rotate around the pivot 65. The end of the seesaw 64 close to the pressing plate 66 descends, and the other end lifts the lifting block 61. The lifting block 61 cooperates with the guide grooves 82 on both sides of the stopper 8 through the guide blocks 613 at both ends of the lift block 61 to achieve the upward and downward movement guidance, so that it can stably move on the stopper 8.

[0040] Since the lifting slope 611 of the lifting block 61 is located below the lowest pipette tip 9, when the lifting block 61 moves upward, the lowest pipette tip 9 is lifted up to leave the bottom of the lowest material discharge chute 5. At the same time, the partition block 612 on the lifting block 61 is located below the two lowest pipette tips 9, which can prevent other pipette tips 9 from moving together when one pipette tip 9 is lifted up.

[0041] After the pipette tip 9 is lifted up, the lifting slope 611 tilts downward, so the pipette tip 9 rolls downward, passes through the unloading slope 81 at the upper end of the limit block 8, and then continues to roll, and is then rolled onto the support frame 7 for easy access by the user. After the pressing plate 66 is released, the rocker 64 returns to its initial position under the action of the return spring 67, and the lifting block 61 also returns to its initial position.

[0042] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
