Description

Technical Field

[0001] The utility model belongs to the field of experimental auxiliary equipment, in particular to a quick box loading device suitable for pipette gun tips. Background Art

[0002] The pipette is a liquid transfer instrument commonly used in scientific research institutions such as universities and research institutes. Bulk gun tips are widely used in universities and research institutes. It is necessary to manually insert the gun tips into the gun tip box, and the process is repeated and time-consuming. There is an auxiliary box loader in the prior art. The box loader has a groove with a corresponding interval with the holes of the gun tip box. The bulk gun tips need to be poured into the box loader in advance, and the box loader is repeatedly shaken to make the tip of the gun tip roll into the groove, and then the gun tips in the groove are separated by a separator to correspond to the gun tip box, and then the subsequent auxiliary box entry is performed. The device needs to be shaken repeatedly to make the gun tip enter the groove, but when the size of the loaded gun tip is small, because the size of the corresponding groove is also very small, it is difficult to roll the gun tip into the groove even if it is shaken and rolled many times in time, which increases the operation time. And the number of gun tips required to be loaded into the gun tip box each time is large, and each box entry operation needs to repeat the shaking step, which consumes the operator's physical strength, which is relatively inconvenient and needs to be improved. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a quick box loading device suitable for pipette tips.

[0004] The utility model adopts the following technical solutions:

[0006] Preferably, the installation groove and the conveying groove bottom sides are formed with limited segments inwardly, a clearance space for the tip of the gun head to pass through is formed between the two limited segments, and the top surface of the limited segment is clamped with the end of the gun head.

[0007] Preferably, a partition is provided at the connection between the installation groove and the conveying groove, and a clearance passage is formed between the bottom of the partition and the top of the limiting section, through which only the tip of the gun head can pass vertically downward.

[0008] Preferably, the pushing and combing mechanism includes a sliding rod and a pushing rod. The sliding rod is slidably arranged on the top of the rear loading box perpendicular to the extension direction of the installation groove. A sliding groove is formed downwardly through the top surface of the sliding rod, and the sliding groove is arranged along the extension direction of the sliding rod. There are several pushing rods, which are slidably arranged in the sliding groove, and the bottom extends downward into the conveying groove to push the gun head in the conveying groove to move with the movement of the sliding rod.

[0009] Preferably, one end of the rear loading box is connected to the front loading box, and the other end is tilted downward in a direction away from the front loading box. The top surface of the rear loading box is parallel to the horizontal plane, and the bottom is tilted downward.

[0010] Preferably, bar magnets are arranged on both sides of the top surface of the rear carrying box, and the sliding rod is made of a magnetic material that can be adsorbed by the magnets. The sliding rod is adsorbed on the bar magnet and can be movably arranged on the top surface of the rear carrying box.

[0011] Preferably, a plurality of evenly spaced partition rods are provided on the partition plug plate, and spaces for accommodating gun tips are formed between adjacent partition rods. A plurality of fixing blocks are provided at the bottom of the front loading box, and fixing holes opposite to the partition rods are provided on the fixing blocks. The partition rods are fixed to the bottom of the front loading box through the fixing holes and evenly space the gun tips in the mounting grooves.

[0012] Preferably, the length of the partition rod gradually shortens along the arrangement direction, and the length of the partition rod at the shortest point is greater than the width of the front loading box, and a continuous inclined surface is formed at the end of the partition rod.

[0013] Preferably, the fixing blocks are symmetrically arranged at the bottom of the front loading box, and the spacing between the fixing blocks on both sides is equal to the width of the gun tip box. Limiting blocks are formed on the opposite surfaces of a pair of fixing blocks away from the through hole direction, and the limiting blocks contact the gun tip box to align the front loading box with the gun tip box.

[0014] Preferably, it also includes a shielding mechanism arranged on the front loading box to shield the through hole, the shielding mechanism includes buckles located on both sides of the through hole, an extension plate extending outward from the bottom of the front loading box, and a baffle that can be raised and lowered and arranged between the two buckles to shield the through hole.

[0015] From the above description of the utility model, it can be known that before the gun head is put into the box, it is first poured into the rear loading box. Since the upper end of the conveying groove of the rear loading box is larger, the gun head can fall directly into the conveying groove, and then the gun head is driven to move forward by the combing mechanism to move in the conveying groove. During the movement, the gun head gradually adjusts its posture in the conveying groove with the conveying groove gradually narrowing under the push of the combing mechanism until the tip faces downward and falls into the bottom of the conveying groove, and finally enters the front loading box to be separated by the partition plate. When entering the box, align the front loading box with the gun tip box and place the gun head into the hole of the gun tip box. After removing the partition plate, push the front loading box to move along one side so that the gun head moves horizontally out of the through hole of the front loading box and falls into the gun tip box. Compared with the prior art, the utility model has the following beneficial effects: by pouring the gun head into the rear loading box in advance, and conveying the gun head through the conveying trough which is wide at the front and narrow at the back, wide at the top and narrow at the bottom, the gun head can automatically fall into the bottom of the conveying trough in the correct posture during the movement, and the gun head can be quickly adjusted to the correct posture without shaking, so as to ensure that the gun head entering the front loading box has the correct posture, and the operation is simple, and the operation before entering the box can be completed by repeatedly pouring the gun head and driving the combing mechanism, which has high work efficiency and high practicality;

[0016] The distance between the partition and the limit section is very small, so that only the gun head with the correct posture (the tip is facing down) can enter the front loading box, and the gun head with the wrong posture will remain in the rear loading box;

[0017] Since the conveying trough is radially distributed in a fan shape, the push rod can be movably arranged in the slide trough to adapt to the movement in the conveying trough;

[0018] The rear loading box is tilted downward, so that the gun head that has not entered the front loading box can fall back to the bottom of the rear loading box as the combing mechanism is pushed backward. When the gun head is poured in for the second time, the gun head can be moved again in the conveying trough with the new gun head to adjust its posture again. The tilting setting can make the gun head fall back normally and participate in the second conveying without manual adjustment, which further improves the work efficiency.

[0019] The sliding rod is attached to the rear loading box by a bar magnet to prevent the sliding rod from falling off during movement and improve the stability of the device;

[0020] The separation rod is gradually shortened and a continuous inclined surface is formed at the end, so as to facilitate the separation of the gun heads closely attached to the installation groove in sequence;

[0021] The fixing block can not only fix the partition plate, but also play the role of positioning the gun head box, and also ensure the stability of the front loading box when it is pulled out;

[0022] The shielding plate shields the through hole to prevent the gun tip entering the mounting groove from being discharged from the through hole when the gun tip is not inserted into the box. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The present invention is further described below through specific implementation methods.

[0033] Reference Figures 1 to 7 As shown, a quick box loading device suitable for pipette tips includes a front loading box 1, a rear loading box 2, a pushing and combing mechanism 3, and a partition insert 4.

[0034] A plurality of installation slots 11 distributed longitudinally are arranged in the front loading box 1. The installation slots 11 are connected vertically and correspond to the holes in each column on the gun tip box one by one. A through hole 12 communicating with the installation slot 11 is arranged on the front side of the front loading box 1. A shielding mechanism 13 is arranged on the front loading box 1. The shielding mechanism 13 includes buckles 131 located on both sides of the through hole 12, an extension plate 132 extending outward from the bottom of the front loading box 1, and a baffle 133 that can be raised and lowered and arranged between the two buckles 131 to shield the through hole 12, so as to prevent the gun tip entering the installation slot 11 from being discharged from the through hole 12 when it is not in the box.

[0035] The rear loading box 2 is connected to the rear end of the front loading box 1, and has a conveying groove 21 formed inside that corresponds to and is connected to the installation groove 11. The cross-section of the conveying groove 21 gradually decreases from top to bottom to the same width as the installation groove 11. The conveying groove 21 is radially distributed in a fan shape and the width of the top end gradually increases in the direction away from the front loading box 1.

[0036] Specifically, the two sides of the bottom of the installation groove 11 and the conveying groove 21 are formed with limited segments 14 inwardly, and a clearance space for the tip of the gun head to pass through is formed between the two limited segments 14, and the top surface of the limited segment 14 is clamped with the end of the gun head. A partition 15 is provided at the connection between the installation groove 11 and the conveying groove 21, and a clearance channel 16 is formed between the bottom of the partition 15 and the top of the limited segment 14, which is only for the tip of the gun head to pass vertically downward. The spacing between the partition 15 and the limited segment 14 is very small, so that only the gun head with the correct posture (the tip is facing downward) can enter the front loading box 1, and the gun head with the wrong posture remains in the rear loading box 2. At the same time, the arrangement of the extension plate 132 does not affect the conveying of the needle by the clearance space, and does not affect the discharge of the needle from the through hole 12 out of the front loading box 1.

[0037] The pushing combing mechanism 3 is slidably arranged in the conveying groove 21 to push the gun head to move and adjust the position in the conveying groove 21. The pushing combing mechanism 3 includes a sliding rod 31 and a pushing rod 32. The sliding rod 31 is slidably arranged on the top of the rear carrier box 2 perpendicular to the extension direction of the installation groove 11. The top surface of the sliding rod 31 is formed with a sliding groove 33 through it downward, and the sliding groove 33 is arranged along the extension direction of the sliding rod 31; there are a plurality of pushing rods 32, which are slidably arranged in the sliding groove 33, and the bottom extends downward into the conveying groove 21 to push the gun head in the conveying groove 21 to move with the movement of the sliding rod 31. Since the conveying groove 21 is radially distributed in a fan shape, the pushing rod 32 can be movably arranged in the sliding groove 33 to adapt to the movement in the conveying groove 21. Specifically, one end of the rear carrier box 2 is connected to the front carrier box 1, and the other end is tilted downward in a direction away from the front carrier box 1. The top surface of the rear carrier box 2 is parallel to the horizontal plane, and the bottom is tilted downward, so that the gun head that has not entered the front carrier box 1 can fall back to the bottom of the rear carrier box 2 when the combing mechanism 3 is pushed to move backward, and can move again in the conveying groove 21 with the new gun head when the gun head is poured in for the second time to adjust the posture again. The tilting setting can make the gun head fall back normally and participate in the second conveying without manual adjustment, which further improves the work efficiency. Furthermore, bar magnets 22 are set on both sides of the top surface of the rear carrier box 2, and the sliding rod 31 is a magnetic material that can be adsorbed by a magnet. The sliding rod 31 is adsorbed on the bar magnetic strip and movably set on the top surface of the rear carrier box 2. The sliding rod 31 is adsorbed on the rear carrier box 2 through the bar magnet 22, so as to prevent the sliding rod 31 from falling off during the movement, thereby improving the stability of the device.

[0038] The partition plug plate 4 is slidably arranged at the bottom of the front loading box 1 to evenly separate the gun heads in the longitudinal direction. A plurality of evenly spaced partition rods 41 are arranged on the partition plug plate 4. Spaces for accommodating gun heads are formed between adjacent partition rods 41. A plurality of fixing blocks 17 are arranged at the bottom of the front loading box 1. The fixing blocks 17 are provided with fixing holes 18 opposite to the partition rods 41. The partition rods 41 are fixed to the bottom of the front loading box 1 through the fixing holes 18 and evenly separate the gun heads in the mounting grooves 11. The length of the partition rods 41 is gradually shortened along the arrangement direction, and the length of the partition rods 41 at the shortest point is greater than the width of the front loading box 1. The ends of the partition rods 41 are formed with continuous inclined surfaces, which facilitates sequentially separating the gun heads that are closely attached in the mounting grooves 11. Preferably, the fixing blocks 17 are symmetrically arranged at the bottom of the front loading box 1, and the spacing between the fixing blocks 17 on both sides is equal to the width of the gun tip box. Limiting blocks 19 are formed on the opposite surfaces of a pair of fixing blocks 17 away from the through hole 12. The limiting blocks 19 contact with the gun tip box to align the front loading box 1 with the gun tip box. The fixing blocks 17 can not only fix the partition plate 4, but also play a role in positioning the gun tip box, and can also ensure the stability of pulling out the front loading box 1.

[0039] Before the gun tip is put into the box, it is first poured into the rear loading box 2. Since the upper end of the conveying groove 21 of the rear loading box 2 is larger, the gun tip can directly fall into the conveying groove 21, and then the combing mechanism 3 is driven to move forward to drive the gun tip to move in the conveying groove 21. During the movement, the gun tip gradually narrows as the conveying groove 21 gradually adjusts its posture in the conveying groove 21 under the push of the combing mechanism 3 until the tip falls into the bottom of the conveying groove 21 with the tip facing downward, and finally enters the front loading box 1 to be separated by the partition plug 4. When entering the box, align the front loading box 1 with the gun tip box and place the gun tip into the hole of the gun tip box. After removing the partition plug 4, push the front loading box 1 to move along one side so that the gun tip moves out of the front loading box 1 horizontally from the through hole 12 and falls into the gun tip box. By pouring the gun heads into the rear loading box 2 in advance and conveying the gun heads through the conveying groove 21 which is wide at the front and narrow at the back, wide at the top and narrow at the bottom, the gun heads can automatically fall into the bottom of the conveying groove 21 in the correct posture during the movement. The gun heads can be quickly adjusted to the correct posture without shaking, ensuring that the posture of the gun heads entering the front loading box 1 is correct. The operation is simple, and the operation before entering the box can be completed by repeatedly pouring the gun heads and driving the combing mechanism 3. The work efficiency is high and the practicability is very high.

[0040] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of implementation of the present utility model. That is, equivalent changes and modifications made according to the scope of the patent application of the present utility model and the contents of the specification should still fall within the scope covered by the patent of the present utility model.
