Description

Technical Field

[0001] The invention relates to the technical field of laboratory equipment for a clinical laboratory, and in particular to a fast loading and sample adding pipette tip device for a clinical laboratory. Background Art

[0002] In modern laboratories, pipette tips are frequently used laboratory consumables, and the efficiency and convenience of their loading and storage are crucial to the smooth conduct of laboratory work. The traditional storage method of pipette tips is relatively simple, usually just placing the tips in ordinary boxes or racks, lacking effective fixing measures. In actual operation, when staff use pipette tips, they are prone to tipping and scattering, which not only wastes time to organize, but also may cause pipette tip contamination, affecting the accuracy of experimental results.

[0003] At the same time, pipettes and sample tips are often stored separately, which requires staff to frequently go back and forth to find pipettes and suitable tips during the experiment, increasing the operation steps and time costs. Moreover, ordinary storage devices are not easy to move, which will cause great inconvenience to staff when experiments need to be conducted in different areas of the laboratory. Based on these problems; It is particularly urgent to develop a device that can quickly load sample tips and facilitate the storage of pipettes and the overall movement of the device. This is the background for the birth of the rapid loading sample tips device for this laboratory. Summary of the invention

[0004] Purpose of the invention: The purpose of the present invention is to improve the efficiency of loading and taking out the sample pipette tip; another purpose of the present invention is to provide a method for integrated storage and convenient movement of the pipette gun and the sample pipette tip.

[0005] Technical solution: A fast loading and adding sample pipette tip device for laboratory, comprising a storage cavity, wherein a plurality of card slots are symmetrically provided inside the storage cavity, a plurality of tip storage plates are snap-connected inside the storage cavity, a plurality of tip storage ports are symmetrically provided on the upper surface of the tip storage plate, and spring slots are symmetrically provided on the outer wall of the storage cavity, the spring slots are slidably connected with card rods, the opposite ends of the card rods are provided with circular grooves, the circular grooves are slidably connected with disks, the opposite sides of the disks are fixedly connected with cylinders, the opposite ends of the cylinders are fixedly connected to the inner walls of the adjacent card slots, and a spring is fixedly connected between the circular grooves and the disks.

[0007] Furthermore, the upper surface of the storage cavity is symmetrically fixedly connected with a guide block, the upper surface of the storage cavity is snap-connected with a top plate, and the lower surface of the storage cavity is symmetrically provided with guide holes, which are snap-connected with the guide block.

[0008] Furthermore, the outer wall of the storage cavity is symmetrically fixedly connected with a locking cavity, the locking cavity is provided with a transverse groove, the interior of the transverse groove is symmetrically provided with movable grooves, the interior of the movable grooves is slidably connected with short rods, the opposite ends of the short rods are commonly fixedly connected with an extrusion plate, the left side of the extrusion plate is fixedly connected with an extrusion block, and the interior of the locking cavity is locked with a locking plate.

[0009] Furthermore, a limiting groove is provided on the outer side wall of the locking plate, a long plate is slidably connected inside the limiting groove, a wedge block is fixedly connected to the right side of the long plate, and a spring 2 is fixedly connected between the outer side wall of the long plate and the limiting groove.

[0012] Beneficial effects: The device has multiple symmetrical card slots inside the storage chamber, which can be snapped together to connect multiple head storage plates. The head storage openings on the upper surfaces of the head storage plates are used to place sample pipette tips. A snap-in rod is slidably connected in the spring slot of the outer wall, and the head storage plate is snapped and fixed by the elastic force of spring 1 to prevent it from moving in the storage chamber. When the head storage plate needs to be taken out, the snap-in rod can be disengaged from the head storage plate by slidingly connecting the vertical plate and the slide slot and squeezing and pulling the vertical plate inward. The operation is simple and convenient, which greatly improves the efficiency of loading and taking sample pipette tips, meets the needs of rapid operation in the laboratory, reduces operation time, and improves work efficiency.

DETAILED DESCRIPTION

[0015] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] Example like Figure 1-7 As shown, a fast loading and adding sample suction tip device for laboratory is provided, comprising a storage chamber 1, wherein a plurality of card slots 2 are symmetrically provided inside the storage chamber 1, a plurality of storage tip plates 3 are connected in a card-engaging manner inside the storage chamber 1, a plurality of storage tip openings 4 are symmetrically provided on the upper surface of the storage tip plates 3, an outer wall of the storage chamber 1 is symmetrically provided with spring slots 5, a card-engaging rod 6 is slidably connected inside the spring slots 5, a circular slot 7 is provided at the opposite ends of the card-engaging rod 6, a circular disc 8 is slidably connected inside the circular slot 7, a cylinder 9 is fixedly connected at the opposite sides of the circular disc 8, the opposite ends of the cylinder 9 are fixedly connected to the inner side walls of the adjacent spring slots 5, a spring 29 is fixedly connected between the circular slot 7 and the circular disc 8, a slide slot 10 is provided on the inner upper surface of the spring slot 5, a vertical plate 11 is fixedly connected to the upper surface of the card-engaging rod 6, and the outer side walls of the vertical plate 11 are slidably connected to the inner side walls of the slide slot 10; When it is necessary to load the sample pipette tip, first slide the storage plate 3 into the storage chamber 1 along the card slot 2 inside the storage chamber 1. The multiple storage ports 4 symmetrically opened on the upper surface of the storage plate 3 are used to place the sample pipette tips. After placing the multiple layers of the storage plate 3, because the outer wall of the storage chamber 1 is symmetrically opened with spring grooves 5, the spring grooves 5 are slidably connected with the engaging rod 6. The circular groove 7 at the opposite end of the engaging rod 6 is slidably connected with a disc 8, and the disc 8 is fixed to the inner wall of the spring groove 5 through a cylinder 9. A spring 29 is fixedly connected between the circular groove 7 and the disc 8. The spring 29 is in a compressed state and will give the engaging rod 6 an elastic force to the outside. When the storage plate 3 completely slides into the card slot 2, the engaging rod 6 slides outward under the action of the spring 29, and the storage plate 3 is clamped and fixed to prevent it from moving in the storage chamber 1. When the pipette tip needs to be loaded, the head of the pipette gun contacts the sample loading pipette tip and loads them together. After one plate of sample loading pipette tips is used up, the next plate can be used to take out the storage plate 3. If you want to take out the storage plate 3, you can use the vertical plate 11. The vertical plate 11 is fixed on the upper surface of the clamping rod 6 and is slidably connected with the slide groove 10 opened on the upper surface of the spring groove 5. Pressing and pulling the vertical plate 11 inwards drives the clamping rod 6 to slide inwards against the elastic force of the spring 1 29, so that the clamping rod 6 is disengaged from the clamping of the storage plate 3. At this time, the storage plate 3 can be smoothly taken out to perform the operation of taking the sample loading pipette tip.

The snap-fitting cavity 14 is provided with a transverse groove 15. When the top plate 12 is covered, the snap-fitting plate 20 will extend into the interior of the snap-fitting cavity 14. At this time, the wedge-shaped block 23 will be snapped into the interior of the transverse groove 15. When it needs to be removed, the two squeeze plates 18 are squeezed at the same time, and the set squeeze blocks 19 will squeeze the two wedge-shaped blocks 23 respectively. At this time, the top plate 12 can be opened, and the handle 26 on the upper surface of the storage cavity 1 is convenient for moving the entire device.

[0018] In this embodiment, a fixing plate 24 is threadedly connected to the front surface of the storage chamber 1, and a pipette gun buckle 25 is fixedly connected to the front surface of the fixing plate 24; The pipette buckle 25 fixedly connected to the front surface of the fixing plate 24 can conveniently fix the pipette on the storage chamber 1, so that the pipette is integrated with the device for storing the sample pipette tip, which is convenient for taking and storing, and the handle 26 on the upper surface of the storage chamber 1 is convenient for moving the entire device.
