Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a pipette tip storage box. Background Art

[0002] Pipette tips are tools used by pipettes to absorb and transfer liquids. They are the most commonly used consumable equipment in laboratories and are usually stored in tip storage boxes.

[0003] A tip storage box, also known as a tip box, is a common device used to store tips in biological and medical laboratories. It is generally a rectangular box body with a lid hinged on the box body, a tray placed inside the box body, and a number of through holes on the tray. When the tips are not in use, they can be inserted into the through holes for neat and orderly arrangement and sealed by closing the lid. When the tips are needed, the lid can be opened to expose the tips for easy access. However, when the lid is opened to take out the tips, all the tips will be directly exposed to the air, increasing the possibility of the tips being contaminated by external impurities, which can easily lead to experimental failure. Therefore, unused tips need to be cleaned when they are used next time, which makes the operation more troublesome, time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of the utility model is to provide a pipette tip storage box in order to solve the above-mentioned problem, which effectively reduces the possibility of the tips being contaminated by external impurities, is convenient to operate, and saves time and effort.

DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figure 1-3As shown, a pipette tip storage box includes a box body 1 and a box cover 2, and the box body 1 and the box cover 2 are made of polypropylene material, which has high strength and good wear resistance, thereby ensuring the structural strength of the storage box and making the storage box have good durability. A support plate 3 is arranged inside the box body 1, and a plurality of through holes 4 are opened on the support plate 3. A baffle plate 5 is arranged inside the box body 1, and the baffle plate 5 is located above the support plate 3. A through hole 6 is opened on the baffle plate 5 corresponding to the through hole 4. A sealing component is arranged at the top of the baffle plate 5 corresponding to the through hole 6. The sealing component includes a connecting seat 7, and a sealing plate 8 for closing the through hole 6 is slidably connected in the connecting seat 7. A slide groove 1 is opened on the connecting seat 7 along the length direction. 2, and a push plate 13 penetrating the slide groove 12 is provided on the top of the sealing plate 8. When the sealing plate 8 needs to be pushed out or into the connecting seat 7, the push plate 13 can be pushed to slide in the slide groove 12. The slide groove 12 can limit the sliding direction of the push plate 13, and the push plate 13 can be used as a force point for pushing the sealing plate 8 to slide, so that the operation becomes easier and more labor-saving. A plurality of sockets 11 for inserting the sealing plate 8 are provided on the top of the baffle 5. When the sealing plate 8 is slid out of the connecting seat 7 and the through hole 6 is closed, the sealing plate 8 can also be inserted into the socket 11. The sealing plate 8 is limited by the socket 11, which can prevent the sealing plate 8 from retracting into the connecting seat 7 due to shaking, thereby preventing the sealing from failing. Thereby, the sealing effect of the sealing plate 8 on the through hole 6 is improved. A pushing assembly is provided on the inner bottom wall of the box body 1 at the position corresponding to the through hole 4. The pushing assembly includes a bracket 9 and an elastic member for pushing the bracket 9 to pop up. When the suction head is placed in the storage box, the suction head can be passed through the through hole 6 and inserted into the through hole 4, so that the bottom end of the suction head contacts the bracket 9 and the top end of the suction head is retracted into the through hole 6. Then, the sealing plate 8 can be slid out of the connecting seat 7 and close the through hole 6, so that the suction head is locked under the baffle 5, so that the suction head is isolated from the outside world. When the required suction head needs to be taken, it is only necessary to slide the sealing plate 8 at this position into the connecting seat 7 so that the sealing plate 8 is away from the through hole 6, thereby opening the through hole 6. , the elastic member can push the bracket 9 to pop up, thereby pushing the top of the suction head out of the through hole 6 for easy taking. Through this arrangement, when taking the suction head alone, the remaining unused suction heads will not be directly exposed to the air, thereby effectively reducing the possibility of the suction head being contaminated by external impurities, eliminating the cumbersome operation of cleaning the suction head, and the operation is more convenient, saving time and effort. A embedding groove 18 is provided on the top of the bracket 9. When the suction head is placed inside the box body 1, the bottom of the suction head will be inserted into the embedding groove 18 and conflict with the bracket 9. The limiting position of the embedding groove 18 can make the contact between the suction head and the bracket 9 more firm, making it difficult for the bracket 9 to detach when the suction head is pushed up, thereby ensuring the lifting effect of the bracket 9.

[0022] See also Figure 3 , Figure 4As shown, the elastic member includes a limiting sleeve 14, and a spring 15 is arranged inside the limiting sleeve 14, one end of the spring 15 is fixedly connected to the inner bottom wall of the limiting sleeve 14, and the other end is fixedly connected to the bottom of the bracket 9. After the suction head is placed inside the box body 1 and sealed by the sealing plate 8, the bottom end of the suction head will contact the bracket 9, so that the spring 15 is compressed and deformed. When the sealing plate 8 is retracted and the perforation 6 is opened, the spring 15 is freed from the pressure constraint and will return to its original shape, so that the bracket 9 can be automatically pushed upward to pop out, and then the top of the suction head is pushed out from the perforation 6. The efficiency is high, the operation is convenient and simple, and the limiting sleeve is used. The setting of 14 can limit the extension and contraction direction of the spring 15 to prevent the spring 15 from being bent due to excessive deformation, thereby extending the service life of the spring 15. A slideway 16 is provided on the inner wall of the limiting sleeve 14 along the length direction, and a slider 17 slidably connected to the inside of the slideway 16 is provided on the side wall of the bracket 9. When the bracket 9 moves up and down, the slider 17 will slide along the slideway 16. The slideway 16 limits the slider 17, so that the movement direction of the bracket 9 can be limited, thereby making the movement of the bracket 9 smoother, and further making the operation of pushing out or inserting the suction head easier and more labor-saving.

[0023] See also Figure 1 , Figure 2 As shown, a plurality of sealing petals 10 are arranged inside the perforation 6. The sealing petals 10 are fan-shaped and elastic. The sealing petals 10 are in contact with each other in a natural state to achieve the closure of the perforation 6. After the pipette tip is placed inside the box body 1 and sealed by the sealing plate 8, the mutual contact between the sealing petals 10 can achieve a further sealing effect, thereby completely isolating the entry of external impurities and effectively ensuring the sealing effect.
